Description

[0001] SINGLE PORT FOR LAPAROSCOPIC SURGERY [0002]

The present invention relates to a single port for laparoscopic surgery in which a surgical instrument or a camera is inserted into an incisional tissue layer during laparoscopic surgery.

The aging of the population, the cosmetic aspect of the patient, the recovery after surgery or the period of hospitalization caused the change from conventional open surgery to laparoscopic surgery. Currently, laparoscopic surgery is divided into single pass laparoscopic surgery and robotic surgery, which are defined as minimal invasive surgery.

Single channel laparoscopic surgery is performed through a single port for laparoscopic surgery, including a surgical instrument channel, a carrera channel, and gas inflow and outflow piping. There are many advantages in terms of cosmetic aspect of patients with single channel laparoscopic surgery, recovery after surgery or shortening of hospitalization period. However, if there are limitations, the operator has to overcome the limit and proceed with surgery.

Specifically, the conventional single port for laparoscopic surgery has a problem in that the distance between the channels in which a surgical instrument or a camera is inserted during surgery is narrow, and the distance between the surgical instruments including the camera during surgery or between the hands of the operator including the camera operator Occurs. That is, the surgical instrument or the camera inserted into the abdominal cavity of the operated person has a narrow motion angle with a narrow interval between the channels, and there is a problem that the hands of the operator or the camera operator outside the abdominal cavity collide with each other.

In addition, the single port for laparoscopic surgery is mounted horizontally on the abdominal incision tissue layer of the operated person, and the surgical instrument or camera is vertically inserted and inserted into the abdominal cavity of the operated subject. Thus, The organ located on the opposite side was difficult to operate. This is because the operator and the surgical site are located symmetrically with respect to the incision site. The conventional two-dimensional port has physical limitations in that it is difficult to operate due to the squeezing or crushing of the surgical instrument.

In addition, in order to overcome the above-mentioned pressing, the surgeon lifts the surgical instrument by itself and not only causes an excessive fatigue to the operator but also has a problem that the uppermost portion of the single port for laparoscopic surgery is peeled from the opposite side of the operator . In addition, there is a problem that it is difficult to secure the visibility of the surgeon because the inside of the abdominal cavity, which is generated by hemostasis with an energy device, which is a hemostasis device using energy such as electricity or ultrasonic waves, is not sufficiently removed.

In order to facilitate understanding of the features of the present invention, a single port for laparoscopic surgery according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Hereinafter, exemplary embodiments will be described on the basis of embodiments best suited for understanding the technical characteristics of the present invention, and the technical features of the present invention are not limited by the illustrated embodiments, And that the present invention may be implemented with other embodiments. Therefore, it is intended that the present invention covers the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents. In order to facilitate understanding of the embodiments to be described below, in the reference numerals shown in the accompanying drawings, the related components among the components that perform the same function in the respective embodiments are denoted by the same or extended line numbers.

FIG. 1 is a perspective view of a single port for laparoscopic surgery according to an embodiment of the present invention, FIG. 2 is an exploded perspective view of the single port for laparoscopic surgery shown in FIG. 1, FIG. 4 is a perspective view of a lower unidirector according to an embodiment of the present invention, and FIG. 5 is a cross-sectional view taken along line AA in FIG.

The single port for laparoscopic surgery according to an embodiment of the present invention includes a channel member 100, a upper undertractor 200, and a lower undertractor 300.

Hereinafter, a single port for laparoscopic surgery including a triangular shape will be described.

The channel member 100 may include a top plate 100 having a triangular shape. The triangular shape includes a shape which is substantially triangular in addition to the triangle. The generally triangular shape includes a shape in which a vertex portion of a triangle forms a curved line or a line segment portion of a triangle forms a curved line. The line segment portion is bent more smoothly than the vertex portion, . A plurality of channels may be formed in the upper plate 110.

The plurality of channels may be close to the corner side of the top plate 110 having a triangular shape. The channel includes a surgical instrument or a camera for viewing the abdominal cavity during surgery. When the plurality of channels are close to the side of the edge of the top plate 110, which is triangular, the distance between the surgical instruments inserted into the other channels may become distant, and interference between the surgical instruments or between the hands of the operator may be reduced.

The plurality of channels may include a surgical instrument channel 120 into which a surgical instrument is inserted and a camera channel 130 into which the camera is inserted. In general, the plurality of channels may be two surgical instrument channels 120 and one camera channel 130.

The camera channel 130 may include a camera insertion tube 132 extending downward by a predetermined distance. When the camera enters the abdominal cavity through the single-port camera channel 130 for laparoscopic surgery, the camera lens may encounter a single-port internal wall, surgical instrument, etc. for laparoscopic surgery. As a result, foreign substances such as blood, fat, moisture, and the like may be adhered to the lens of the camera, which may obscure the view of the operator through the camera. Therefore, the operator has to remove the camera from the abdominal cavity of the surgeon to clean the foreign body and perform the operation. However, if the camera insertion tube 132 is formed in the camera channel 130, contamination of the camera lens can be effectively prevented. The camera insertion tube 132 may extend downward to the lower surface 170 of the channel member 100.

The channel member 100 may include an in-flow channel 140 and an out-flow channel 150.

During laparoscopic surgery, smokes occur within the abdominal cavity. Such smog interferes with the operator's vision, so ventilation in the abdominal cavity is necessary.

For this ventilation, a single port for laparoscopic surgery generally has a gas intake tube for sending clear gas into the abdominal cavity and a gas exhaust tube for exhausting the gas in the abdominal cavity to the outside. However, the conventional laparoscopic single-port gas-insufflation tube does not have a separate tube directed into the abdominal cavity of the operated person. Accordingly, there is a problem that the gas introduced through the gas intake tube flows out immediately through the gas exhaust pipe formed adjacent to the gas exhaust tube, that is, the gas does not circulate throughout the peritoneal cavity and flows out immediately, and the smog in the peritoneal cavity can not be removed smoothly.

Accordingly, the single port for laparoscopic surgery according to an embodiment of the present invention may include a gas intake tube 140 extending downward from the incisional tissue layer of the operator, and a gas outlet end 142 of the gas intake tube 140 May extend radially. Smoke in the abdominal cavity can be smoothly removed by the gas intake tube 140.

The upper can retractor 200 may have a triangular annular shape. The triangular, triangular, triangular shape includes a generally triangular shape. The generally triangular shape includes a shape in which a vertex portion of a triangle forms a curved line or a triangle-shaped line segment portion forms a curved line. The line segment portion is bent more smoothly than the vertex portion, Shape. The upper can retractor 200 is coupled to the lower side of the channel member 100. A groove 212 may be formed on the upper surface of the upper can retractor 100. The groove 212 may have a triangular annular shape and a radially waved shape.

The channel member 100 may be made of a material that is softer than the upper wing retractor 200. At this time, a first inclined surface 214 and a second inclined surface 216 may be formed on the upper surface of the upper wound retractor 200 so as to be downward from both sides of one side of the triangular shape and meet at the center.

In this case, the space occupied by the first wing retractor 200 and the second wing retractor 200 by the first inclined surface 214 and the second inclined surface 216 is smaller than the space occupied by the upper wing retractor 200, It can be filled by a part.

The channel member 100 made of a soft material can be pressed more easily than the upper wound retractor 200 and the first and second inclined surfaces 214 and 216 can be inserted into the abdominal cavity The inserted surgical instrument can be laid down more obliquely. Therefore, the operation of the organ located in the symmetrical direction of the origin of the operator based on the incision can be made easier.

The channel member 100 may include a coupling protrusion 160 for supporting the upper wing retractor 200. The upper wing retractor 200 can be coupled to the lower side of the channel member 100 by the engaging projections 160. [

Referring to FIG. 5, the length l1 of the engaging protrusion 160 of the corresponding portion and the horizontal diameter 12 of the upper can retractor 200 may be the same. The same includes approximately the same case. The term generally refers to a case where the length 11 of the coupling protrusion 160 and the horizontal diameter 12 of the upper can retractor 200 are only slightly different from each other so that the same can be seen. When the length l1 of the coupling protrusion 160 is too short, the channel member 100 may easily be detached from the upper wing retractor 200 and may be disturbed during the operation, and the length l1 of the coupling protrusion 160 This is because it is not easy to connect the upper undator retractor 200 to the channel member 100 when the length is too long.

The lower undator retractor 300 may have a triangular annular shape. The triangular, triangular, triangular shape includes a generally triangular shape. The generally triangular shape includes a shape in which a vertex portion of a triangle forms a curve or a triangle-shaped line segment portion forms a curved line. The line segment portion is bent more smoothly than the vertex portion, Shape. The lower wound retractor 200 is engaged with the upper wound retractor 200. The sleeve 400 has a predetermined elasticity, and the hollow of the upper and lower undatored retractors 300 and 300, which are annular, is coupled to communicate with each other.

The channel member 100, the upper wound retractor 200 and the lower wound retractor 300 are sequentially connected to each other so that the channel member 100, to which the upper wound retractor 200 is coupled, And the lower undator retractor 300 may have the same directionality with each other.

That is, the upper and lower wound retractors 200 and 300 are coupled by the sleeve 400 such that their triangular shapes have the same directionality, and the upper wound retractor 200 is coupled to the channel member 100, And the triangular shape may be combined so as to have the same directionality.

When the laparoscopic single port for laparoscopic surgery is viewed from above, the triangular shape is positioned such that its corners are directed in the same direction.

Hereinafter, a single port for laparoscopic surgery refracted close to one side will be described. A duplicate description of the single port for laparoscopic surgery including the above-described triangular shape will be omitted.

The channel member 100 may be formed such that its lower surface is refracted with reference to a line near one side (the right side in FIG. 5). That is, the inclined portion 172 and the horizontal portion 174 may be formed on the lower surface of the channel member 100 on both sides with reference to the line. At this time, the horizontal portion 174 may be formed close to the one side surface. The one side may be a surface facing the operator during laparoscopic surgery.

As described above, the channel member 100 includes a tubular gas intake tube 140, the gas intake tube 140 extends downward from the incisional tissue layer of the operator, and the gas The outlet end 142 may extend radially.

At this time, two surgical instrument channels 120 may be formed close to the one side surface of the channel member 100. When the one side is a surface facing the operator during laparoscopic surgery, the two surgical instrument channels 120 are biased toward the operator.

Meanwhile, the two surgical instrument channels 120 are spaced apart from each other, and the gas inlet tube 140 may be formed between the two surgical instrument channels 120.

When the surgical instrument channel 120 and the gas intake tube 140 are formed at the above positions, interference between the surgical instrument and the gas outlet end 142 can be prevented. When the one side is the surface facing the operator in the laparoscopic surgery, the surgical instrument is directed to the opposite side of the operator based on the incision, and the gas outlet end 142 is directed toward the operator.

Meanwhile, when the two surgical instrument channels 120 are formed close to the one side surface, the camera channel 130 may be spaced apart from the one side surface. When the one side is the side facing the operator in laparoscopic surgery, the camera channel 130 is positioned in the opposite direction of the operator.

By forming the surgical instrument channel 120 and the camera channel 130 as described above, interference between the surgical instruments including the camera or between the hands of the operator including the camera operator can be minimized.

The one side is disposed so as to face downward, i.e., toward the legs of the operated person, for the tilting arrangement of the single port for laparoscopic surgery according to the present invention during the operation, which will be described later.

The upper plate 110 of the channel member 100 may be formed parallel to the inclined portion 172 due to the refraction of the lower surface. This is to make the surgical instrument and the camera inserted in the single port for laparoscopic surgery according to the present invention obliquely laid. The parallel includes a case of being substantially parallel. The generally parallel means that the upper plate 110 of the channel member 100 is not finely parallel to the inclined portion 172 so that it can be seen as in the parallel case. The details will be described later.

The upper can retractor 200 can be refracted with reference to a line close to one side (the right side in Fig. 5). That is, the upper wing retractor 200 may be formed with the inclined portion 232 and the horizontal portion 234 on both sides with reference to the line. At this time, the horizontal portion 234 may be formed close to the one side surface. The one side may be a side facing the operator during laparoscopic surgery.

The lower wound retractor 300 can be refracted with reference to a line close to one side (the right side in Fig. 5). That is, the lower wing retractor 300 may be formed with the inclined portion 322 and the horizontal portion 324 on both sides with reference to the line. At this time, the horizontal portion 324 may be formed close to the one side surface. The one side may be a side facing the operator during laparoscopic surgery.

The lower surface of the channel member 100, the upper undertractor 200 and the lower undertractor 300, which are refracted with reference to a line close to the one side surface, are sequentially connected, Lt; / RTI >

That is, the upper and lower wound retractors 200 and 300 are coupled by the sleeve 400 so that one side of the upper wound retractor 200 and the lower wound retractor 300 have the same directionality. When the upper wound retractor 200 is the channel member 100 And one side thereof may have the same directionality.

When the single port for laparoscopic surgery is viewed from above, the one side is positioned in the same direction.

On the other hand, the angle formed between the inclined portions 172, 232, and 322 of the channel member 100, the upper and lower undo retractors 200 and 300 with the horizontal portions 174, 234, a) may be preferably about 24 degrees.

Hereinafter, a single port for laparoscopic surgery including a triangular shape and being refracted close to one side will be described. The description of the single port for laparoscopic surgery including the above-described triangular shape or refracting close to one side will not be repeated.

The channel member 100 includes a top plate 110 having a triangular shape, and the bottom surface thereof may be refracted with reference to a line parallel to and adjacent to the one side 112 of the triangular shape. The triangular shape includes a shape which is substantially triangular in addition to the triangle. The generally triangular shape includes a shape in which a vertex portion of a triangle forms a curved line or a line segment portion of a triangle forms a curved line. The line segment portion is bent more smoothly than the vertex portion, . In addition, the parallel lines include substantially parallel lines. The substantially parallel line means a line that is not finely parallel to the one side 112 so as to be seen as the parallel line.

In this case, the surgical instrument channel 120 may be formed close to the one side 112. In addition, the camera channel 130 may be spaced apart from the one side 112.

The upper woven retractor 200 may have a triangular annular shape and may be bent with respect to a line parallel to and adjacent to the one side portion 210 forming the triangular shape. In the triangular annulus, the triangle includes a shape which is substantially triangular in addition to the triangle. The generally triangular shape includes a shape in which a vertex portion of a triangle forms a curved line or a line segment portion of a triangle forms a curved line. The line segment portion is bent more smoothly than the vertex portion, . In addition, the parallel lines include substantially parallel lines. The substantially parallel line means a line which is not parallel to the one side portion 210 so as to be viewed as the parallel line.

A groove 212 formed radially on the upper surface of the upper can retractor 200 may be formed at the center in the longitudinal direction of the side portion 210.

The first inclined surface 214 and the second inclined surface 216 formed on the upper can retractor 200 may be formed on the upper surface of the side portion 210. [

The lower undator retractor 300 has a triangular annular shape and can be refracted based on a line parallel to and adjacent to the one side 310 forming the triangle. In the triangular annulus, the triangle includes a shape which is substantially triangular in addition to the triangle. The generally triangular shape includes a shape in which a vertex portion of a triangle forms a curved line or a line segment portion of a triangle forms a curved line. The line segment portion is bent more smoothly than the vertex portion, . In addition, the parallel lines include substantially parallel lines. The substantially parallel line means a line that is not finely parallel to the one side portion 310 so as to be viewed as the parallel line.

On the other hand, one side 112 of the channel member 100, a side edge 210 of the upper side retractor, and a side edge 310 of the lower side retractor may have the same direction.

In this case, when the single port for laparoscopic surgery is viewed from above, one side 112 and two sides 210 and 310 are positioned in the same direction.

6 is a perspective view showing a state in which the upper radiator is bent when the sleeve is curled in the upper radiator.

When the operation is performed using the single port for laparoscopic surgery according to the present invention, the abdomen of the operated person is cut and the lower wound retractor 300 is inserted into the abdominal cavity of the operated person. Thereafter, the upper can retractor 200 is rotated several times in the direction of the arrow shown in Fig.

In this case, the sleeve 400 is dried on the outer surface of the upper undocked retractor 200, and the length of the sleeve 400 between the upper undocked retractor 200 and the lower undocked retractor 300 is shortened. As a result, the upper wound retractor 200 is brought into close contact with the inside of the incision tissue layer of the operated person, and the lower wound retractor 300 is brought into close contact with the inside.

On the other hand, since the sleeve 400 to be dried on the outer surface of the upper can retractor 200 has a predetermined elasticity, the upper can retractor 200 is pressurized in the center direction of the annular shape.

Therefore, the upper undator retractor 200 is folded about the groove 212. As a result, the side of the groove 212 is pressurized downward, and the pressure advantageously serves to tilt the single port for laparoscopic surgery according to the present invention during surgery. The tilting arrangement of the single port for laparoscopic surgery will be described later.

On the other hand, when the upper wing retractor 200 is a circular ring, the upper wing retractor 200 can be easily dried as shown in Fig. However, if the upper wing retractor 200 is a triangular annulus, it may not be easy to swing the upper wing retractor 200. Therefore, the groove portion 212 that is easily folded relative to other portions is formed, so that the upper woven retractor 200 can be easily dried.

FIG. 7 is a view showing the use state of the single port for laparoscopic surgery shown in FIG. 1. FIG.

In general, a single port for laparoscopic surgery is mounted on an incised tissue layer 600 by cutting the skin around the navel of the operator. In addition, the human organ (v) is located symmetrically with the operator relative to the incision site. Therefore, when the operator performs laparoscopic surgery using a single port for laparoscopic surgery, the surgical instrument 500 or the camera 510 inserted into the abdominal cavity through the single port for laparoscopic surgery should be laid down at an angle.

The single port for laparoscopic surgery according to the present invention is refracted on the basis of a line close to one side of the lower surface 170 of the channel member 100, the upper tractor 200 and the lower tractor 300. In the case where the single port for laparoscopic surgery according to the present invention includes a triangular shape, the side port 112 of the upper plate 110 of the single-port channel member 100 for laparoscopic surgery according to the present invention, 200 and the one side 310 of the lower wound retractor 300. In this case,

The single port for laparoscopic surgery according to the present invention can be disposed obliquely by the refraction. That is, the inclined portions 172, 232, and 322 of each of the channel member 100, the upper and lower undo tractors 200 and 300 are arranged at a predetermined angle with the ground, 174, 234, and 324 may be disposed substantially parallel to the ground.

By the inclined arrangement, the surgical instrument 500 or the camera 510 inserted into the abdominal cavity through the single port for laparoscopic surgery according to the present invention can be easily laid down at an angle.

As described above, the channel member 100 is refracted with reference to a line near its one side, and the top plate 110 of the channel member 100 is parallel to the inclined portion 172 due to the refraction . Since the upper plate 110 is formed as described above, the surgical instrument 500, the camera 510, and the like can be easily laid down at an angle.

6), the upper end retractor 200 is pressurized downward because the upper end retractor 200 is curled around the groove portion 212 by being engaged with the sleeve 400 having a certain elasticity. Thus, the single port for laparoscopic surgery according to the present invention can more easily maintain the inclined arrangement.

FIG. 8 is a view for explaining gas circulation in the abdominal cavity by the single port for laparoscopic surgery shown in FIG. 1. FIG.

As described above, during laparoscopic surgery, smokes occur in the abdominal cavity. Such smog interferes with the operator's vision, so ventilation in the abdominal cavity is necessary.

The single port for laparoscopic surgery according to the present invention may include a gas intake tube 140 extending downward from an incisional tissue layer 600 of an operator and a gas outlet end 142 of the gas intake tube 140, May extend radially.

In this case, the gas introduced into the abdominal cavity from the gas outlet end 142 is radially ejected from the lower side of the incisional tissue layer 600. When the gas outlet end 142 extends radially, the gas exhaust pipe 150 is positioned opposite the gas outlet end 142.

Accordingly, the gas blown from the gas outlet end 412 flows through the gas exhaust pipe 150 after circulating the entire inside of the abdominal cavity. Therefore, ventilation in the abdominal cavity can be performed more smoothly.

9 is a view for explaining a difference between a circular port and a triangular port for laparoscopic surgery.

A single port for laparoscopic surgery typically has three channels. The channel usually consists of two surgical instrument channels 120 and one camera channel 130. The greater the distance between the three channels, the less interference between the surgical instruments including the camera or between the hands of the operator including the camera operator, and the operator can easily perform the surgery.

On the other hand, as the area occupied by the single port for laparoscopic surgery is small, there is an advantage that the incision of the surgeon can be made less.

Referring to FIG. 9, when three channels 120 and 130 are all formed, a single port for laparoscopic surgery is circular, or a triangle or a channel has the same distance. Nevertheless, the area occupied by the triangle is much smaller than the area occupied by the circle.

In other words, compared to a circular single-port surgical port, the triangular laparoscopic single port can reduce the area occupied by a single port for laparoscopic surgery, while increasing the distance between channels.

That is, the single port for laparoscopic surgery, which is a triangle, has the effect of reducing the interference between the surgical instruments including the camera or between the hands of the operator including the camera operator, and at the same time, cutting the skin of the operator.

10 is a view for explaining blood flow circulation of an operator in accordance with a circular port and a triangular laparoscopic single port.

As described above, the single port for laparoscopic surgery is mounted around the navel of the operated person. The blood flow around the navel is largely divided into the blood flow from the lower side (the leg side of the operated person) to the uvula side and the upper side The blood flow in the direction of the umbilicus.

Referring to FIG. 10 (a), in the case of a circular laparoscopic single port, the flow from the lower side to the umbilical side is almost perpendicular to the single port for laparoscopic surgery. In addition, the blood flow from the upper side to the umbilical side is almost perpendicular to the single port for laparoscopic surgery. Therefore, the blood is not transmitted to the relatively large area (p1, p2), resulting in an ischemic phenomenon.

Referring to FIG. 10 (b), in the case of a triple laparoscopic single port, blood flow in the direction from the lower side to the umbilical end is almost perpendicular to the single port for laparoscopic surgery. However, blood flow in the direction from the upper side to the umbilical artery meets about 120 degrees with the single port for laparoscopic surgery, and the blood flow is hardly subjected to resistance by the single port for laparoscopic surgery. As a result, the ischemic phenomenon appears only at the points p3 and p4 having a relatively small area.

That is, the phenomenon of ischemic phenomenon can be remarkably reduced by the single port for laparoscopic surgery including the triangular shape according to the present invention.

11 is a perspective view of a single port for laparoscopic surgery according to another embodiment of the present invention.

Referring to FIG. 11, the single-port channel member 100 for laparoscopic surgery according to another embodiment of the present invention may further include a wrinkle portion 114. The corrugated portion 114 extends upward from the channel member 100. Further, the upper plate 110 of the channel member 100 is formed to extend from the corrugated portion 114.

The pleats 114 may have a bellows shape and may extend upwardly or downwardly.

Therefore, a surgical instrument or a camera inserted in the surgical instrument channel 120 or the camera channel 130 of the upper plate 110 can be operated in a wider range. Thereby, the surgical instrument or the camera is further slanted so that the angle of operation can be more easily maintained.

In addition, more flexible coping can be possible at the time of surgery of an organ biased to the left or right side of the operator.
