Detailed Description
In order to further describe the technical means and effects adopted for achieving the preset aim of the invention, the following detailed description refers to the specific implementation, structure, characteristics and effects according to the present invention with reference to the accompanying drawings and preferred embodiments.
When the existing endoscope is used for performing tissue excision operation, on one hand, the large incision caused by the open operation is traumatic to a patient; on one hand, the doctor repeatedly performs complex operation of dividing tumors in the operation process; on the one hand, when the crushed tissues are divided, the problem of spreading and transferring the tissues in the body is solved, for example, the hysteromyoma removing operation under a hysteroscope adopts an electric crusher to crush and take out the self-retaining myoma, a large amount of tissue fragments are spread widely in the pelvic cavity and the abdominal cavity, and the tissue fragments enter the abdominal cavity of a human body and are easy to cause tissue transfer.
In view of the above, the technical scheme of the invention provides a tissue smashing and sucking device. The tissue disruption and suction device includes a puncture unit, a disruption and suction unit, and a shield. The isolation cover is provided with at least one opening. When the puncture part enters the vicinity of the tissue to be crushed of the human body, the isolation cover extends out of the puncture part, and the tissue to be crushed is covered through the opening on the isolation cover; then, the opening is tightened, and the pulverization suction portion is introduced into the inside of the shield, so that the tissue is pulverized and sucked out. The tissue disruption and suction device according to the present invention will be described in detail with reference to examples.
Example 1
Referring to fig. 1 and 2, fig. 1 is a schematic structural view of a tissue disruption and suction device according to an embodiment of the present invention; fig. 2 is a schematic view of the first opening of the tissue morcellating suction device of fig. 1 retracted to the penetrating portion. The tissue disruption and suction device 100 includes a puncture unit 110, a disruption and suction unit 120, and a shield 131. The second tissue 220 of a lesion grows on the surface of the first tissue 210 in the abdominal cavity of the patient 200, and the doctor needs to cut and free the second tissue 220 in the abdominal cavity, and then the second tissue is integrally put into the shielding cover 131 of the tissue morcellating and sucking device 100 of the present invention to break up and suck, and then sucked and drawn out from the body of the patient 200.
The piercing portion 110 has a hollow tubular lumen for piercing the patient 200. The location and angle of penetration may be determined via ultrasound imaging, X-ray imaging, or laparoscopy. The smashing and sucking part 120 is located in the inner cavity of the puncture part 110, and can be extended to the position of the second tissue 220 through the puncture part 110 to smash and suck out the second tissue 220. The comminution suction portion 120 may include at least one ultrasonic suction blade.
The ultrasonic suction knife can transmit longitudinal ultrasonic energy to tissues, and the cutting, hemostasis and fine separation can be performed by utilizing different actions of different tissues on the ultrasonic. The main principle is instantaneous impact acceleration, micro-acoustic flow and acoustic cavitation. The ultrasonic suction knife destroys and sucks out tissue cells with high water content, and simultaneously, can ensure that the tissue with high collagen content and stronger elasticity is intact, so that the operation is performed under the conditions of safety, little bleeding or no bleeding. For example, when cutting liver tissue, the ultrasonic suction knife only smashes and sucks liver tissue cells, so that blood vessels, bile ducts and the like in the liver tissue are kept intact, and bleeding can be avoided. When the brain tissue is cut, only the brain tissue cells are crushed and sucked, so that blood vessels, nerve fibers and the like in the brain tissue cells are preserved and unhappied, and therefore, the brain tissue can not bleed. When a tumor containing a capsule is resected, only the tumor tissue is crushed and sucked away, while the capsule remains intact, but it becomes loose and is very easily separated from the surrounding tissue.
The pulverizing suction unit 120 includes a treatment head tip, a negative pressure suction unit, and an energy emitting unit. Wherein the treatment head tip has a hollow tubular lumen and is capable of morcellating the second tissue 220 under the drive of the energy emitting portion.
The shielding cover 131 is in a bag shape, is positioned at the tail end of the puncture part 110, and can extend out of the inner cavity of the puncture part 110.
The cage 131 has a first opening 132 for the second tissue 220 to enter the cage 131, the first opening 132 having a circumference greater than or equal to 1 cm and less than or equal to 100 cm. The shielding cover 131 further comprises a second opening 136 for allowing the tip of the therapeutic head and/or the negative pressure suction part of the smashing suction part to enter the shielding cover 131, and after the tip of the therapeutic head and/or the negative pressure suction part enter the shielding cover, the second tissue in the shielding cover can be smashed, and the smashed second tissue is sucked out. The second opening 136 matches the cross-sectional shape and cross-sectional size of the treatment head tip to prevent the second tissue being morcellated from overflowing as much as possible. For the second tissues to be crushed with different sizes at different positions, the isolation covers 131 with different sizes can be selected. The first opening 132 and the second opening 136 may be hard openings.
The tissue morcellating suction device 100 further includes a pulling member (not shown) to which the first opening 132 is coupled, the pulling member pulling the first opening 132 into the hollow tubular lumen of the penetrating member 110, i.e., the first opening 132 is retracted, and the second tissue 220 is isolated from the body lumen, when the second tissue is introduced into the shield 131 through the first opening 132. When morcellating the second tissue, the physician first selects the second tissue morcellating suction device 100 having the appropriate shield 131 according to the size and shape of the second tissue; next, the puncture section 110 of the second tissue morcellating suction device 100 is punctured into the body of the patient 200 via the abdominal cavity of the patient 200.
The working process of the pulverizing and sucking apparatus of this embodiment is as follows:
a first tissue 210 of the patient 200 is grown with a second tissue 220, the second tissue 220 being partially embedded within the first tissue 210. When morcellating the second tissue, the physician first selects the tissue morcellating suction device 100 having the appropriate shield 131 according to the size and shape of the second tissue; then, the doctor releases the second tissue 220 by excision or the like, and pierces the puncture section 110 of the tissue reduction suction device 100 into the body via the abdominal cavity of the patient 200. As previously mentioned, the location and angle of penetration may be determined via ultrasound imaging, X-ray imaging, or laparoscopy. After the puncture section 110 reaches a predetermined position near the second tissue, the doctor controls the tissue morcellating suction device 100 to extend the shield 131 out of the lumen of the puncture section 110. After the shield 131 leaves the lumen of the puncture section 110, the first opening 132 is opened. Then, the first opening 132 encloses the second tissue 220 to be crushed inside the shielding cover 131. The first opening 132 of the shield is retracted by the pulling member into the lumen of the piercing portion 110 for cinching.
Then, the doctor controls the ultrasonic suction blade of the tissue morcellating suction device 100 to extend from the piercing portion 110 and the second opening 136 of the shield into the shield 131 to perform a second tissue morcellating and/or suction operation. At this time, since the first opening 132 and the second opening 136 of the bag-like shield are both located in the puncture section 110, the second tissue debris, body fluid, and the like do not ooze into the abdominal cavity.
Example two
Referring to fig. 3 and 4, fig. 3 is a schematic structural view of a tissue disruption and suction device according to another embodiment of the present invention; fig. 4 is a schematic view of the first opening of the tissue morcellating suction device of fig. 3 retracted to the penetrating portion.
The difference between this embodiment and the first embodiment is that the shielding cover 131 has only a first opening 132, and the traction component pulls the first opening into the hollow tubular cavity of the puncture part after the second tissue 220 enters the shielding cover 131, so as to isolate the second tissue from the body cavity. The treatment head tip of the crushing and sucking part enters the shielding cover through the part of the first opening 132 positioned in the inner cavity of the puncture part to perform crushing or sucking operation.
Example III
Referring to fig. 5, fig. 5 is a schematic structural view of a tissue disruption and suction device according to an embodiment of the present invention. The tissue morcellating suction device 100 includes a piercing portion 110, a morcellating suction portion 120, and a package spacer assembly 130. A second tissue 220 is grown on the surface of the first tissue 210 in the abdominal cavity of the patient 200, and a portion of the second tissue 220 protrudes from the first tissue 210 and a portion is embedded in the first tissue 210.
The puncturing portion 110 includes a hollow tubular interior for performing puncturing of the patient 200. The location and angle of penetration may be determined via ultrasound imaging, X-ray imaging, or laparoscopy. When puncturing is performed, the crushing suction part 120 and the package isolation assembly 130 are both positioned in the inner cavity of the puncturing part 110; when the tissue morcellating suction device 100 reaches a predetermined location, the morcellating suction portion 120 and the package spacer assembly 130 may extend from the lumen of the piercing portion 110.
The wrapping and isolating assembly 130 includes a telescopic portion 134 disposed between the inner cavity of the piercing portion 110 and the pulverizing and sucking portion 120, and an isolating cover 131 connected to the end of the telescopic portion 134, where the isolating cover 131 can extend out from the inner cavity of the piercing portion 110 and form an umbrella-shaped or ellipsoidal structure. When the puncture part 110 reaches a predetermined position, the telescopic part 134 of the wrapping and isolating assembly 130 extends to the position where the second tissue is located, so that the isolating cover 131 extends out of the inner cavity of the puncture part 110. The shield 131 has a resilient and expandable structure (described in detail below) that expands over the second tissue when it extends beyond the piercing portion 110. The cage 131 may be designed in different shapes and sizes depending on the second tissue type and the second tissue morphology.
The cage surrounding the isolation assembly 130 further includes a first opening 132, and the first opening 132 is located at the edge of the cage 131. For the second tissue embedded on the surface of the first tissue, the isolation cover 131 can be unfolded like an umbrella; for the second tissue protruding or hanging from the surface of the first tissue, the shielding cover 131 can be firstly opened by an umbrella shape at one end of the second tissue, and then the opening is tightened at the other end of the second tissue, so as to form an ellipsoidal structure. The details of the embodiments are described below. The first opening is made of an elastic material and is positioned at the edge of the isolation cover. The shield also has a second opening for the tip of the treatment head of the comminution suction and/or the negative pressure suction to enter the shield. The second opening is matched with the cross-sectional shape and the cross-sectional size of the tip of the treatment head.
The aspiration unit 120 is located within the lumen of the puncture unit 110 and can extend from the distal end of the puncture unit 110 to the second tissue 220. The crushing and sucking part 120 includes a treatment head tip, a negative pressure sucking part and an energy emitting part, wherein the treatment head tip has a hollow tubular cavity and is capable of crushing the second tissue under the driving of the energy emitting part.
The following describes the operation of the tissue morcellating suction device in accordance with this embodiment in combination with the detailed description.
A first tissue 210 of the patient 200 has a second tissue 220, the second tissue 220 being partially embedded within the first tissue 210. When morcellating the second tissue, the physician first selects the tissue morcellating suction device 100 having the appropriate shield 131 according to the size and shape of the second tissue; then, the doctor releases the second tissue 220 by excision or the like, and punctures the puncture section 110 of the second tissue reduction suction device 100 into the body of the patient 200 via the abdominal cavity of the patient 200. As previously mentioned, the location and angle of penetration may be determined via ultrasound imaging, X-ray imaging, or laparoscopy. After the puncture section 110 reaches a predetermined location near the second tissue, the physician controls the tissue morcellating suction device 100 to extend the shield 131, which encloses the isolation assembly 130, out of the lumen of the puncture section 110. After the shielding cover 131 leaves the inner cavity of the puncture part 110, the shielding cover is opened on the surface of the second tissue 220, and the edge of the shielding cover 131 is attached to the first tissue 210.
Then, the doctor controls the crushing suction part 120 of the tissue crushing suction device 100 to extend out of the puncture part 110, and performs a second tissue crushing operation; at the same time, an aspiration portion (not shown) aspirates the pulverized second tissue debris, body fluid, etc. out of the patient 200. At this time, since the spacer 131 is spread out of the second tissue 220, the second tissue debris, body fluid, and the like are less exuded into the abdominal cavity.
In the present embodiment, the shield 131 may have the following structure. Referring to fig. 6, fig. 6 is a schematic view of a wrapping and isolating assembly in a tissue morcellating suction device according to an embodiment of the present invention. The wrap isolation assembly 130 includes a telescoping portion 134, an isolation cover 131, and an elastic member 135. The isolation cover 131 comprises a plurality of flexible supports 137 and an elastic membrane, wherein the elastic membrane is covered on the flexible supports 137 and is fixedly connected with the flexible supports 137, and a second opening 136 is formed in the middle of the elastic membrane and used for passing through a crushing suction part, such as an ultrasonic suction knife and the like. An elastic member 135 is provided between the end of the flexible support 137 and the end of the flexible support 134, and when the flexible support 134 withdraws the shield 131 from the puncture part 110, the elastic member 135 springs open to separate the end of the flexible support 137 from the flexible support 134, so that the elastic membrane can be opened under the support of the flexible support 137.
The end of each flexible scaffold 137 facing the second tissue may also have a hard node so that the flexible scaffold 137 and the elastic membrane conform to the first tissue surface. The number of the flexible supports may be plural, for example, 6, 8 or 12, etc., and the plural and uniformly arranged flexible supports may make the shielding cover 131 regular hemispherical or umbrella-shaped.
The length of each telescoping portion 134 corresponding to flexible support 137 is individually controllable so that, for irregular first tissue 210 surfaces, a close fit of the edges of cage 131 thereto is still ensured as much as possible.
In other embodiments, the cage 131 may also be opened in other mechanical ways. For example, the flexible support 137 in the present embodiment may be replaced with a flexible board.
Example IV
Referring to fig. 7, fig. 7 is a schematic structural view of a tissue disruption and suction device according to another embodiment of the present invention. In this embodiment, a first tissue 210 of the patient 200 is grown with a second tissue 220, the second tissue 220 overhanging the surface of the first tissue 210. The tissue morcellating suction device 100 includes a piercing portion 110, a morcellating suction portion 120, and a package spacer assembly 130.
The difference between this embodiment and the third embodiment is that the package spacer assembly 130 further includes a first opening 132, and the first opening 132 is made of an elastic material and is located at the edge of the spacer 131. The first opening 132 has a circumference greater than or equal to 1 cm and less than or equal to 100 cm. The length of the first opening 132 may vary depending on where the edge of the cage 131 is located in the second tissue 220. When the shield 131 just protrudes from the puncture part 110, the length of the edge of the shield 131 increases, and the length of the first opening 132 also increases gradually; when the shielding cover 131 completely covers the second tissue 220, the first opening 132 is elastically contracted by itself, so that the edge of the shielding cover 131 is attached to the connection between the second tissue 220 and the first tissue 210. To this end, the debris is completely enclosed within the cage 131 when the second tissue is morcellated, without being widely dispersed within the pelvic cavity.
Example five
Referring to fig. 8, a schematic structural view of a tissue morcellating suction device according to a further embodiment of the present invention is shown in fig. 8. In this embodiment, a first tissue 210 of the patient 200 has a second tissue 220, and the second tissue 220 depends from the surface of the first tissue 210. The tissue morcellating suction device 100 includes a piercing portion 110, a morcellating suction portion 120, and a package spacer assembly 130.
The third embodiment is different from the third embodiment in that the package isolation assembly 130 further includes a first opening 132 and a traction wire 133. The first opening 132 is located at the edge of the shielding cover 131, and the pulling wire extends around the first opening 132 and through the shielding cover 131 and the inner cavity of the piercing part 110, and is connected to a pulling member (not shown). In this embodiment, the physician can control the amount of tightening of the first opening 132 via the pull wire.
Example six
The first embodiment is different from the first embodiment in that a pulling wire is also connected to the first opening of the bag-type isolation cover, and the first opening can be pulled into the inner cavity of the puncture part by the pulling wire.
Example seven
Referring to fig. 9, fig. 9 is a schematic structural view of a tissue morcellating suction device according to still another embodiment of the present invention, wherein a blocking ring is provided between a hollow cavity of the piercing portion and the ultrasonic suction blade. The tissue morcellating and aspirating device of this embodiment is similar to the sixth embodiment, except that a barrier ring 140 is disposed between the hollow tubular lumen of the piercing portion 110 and the tip of the therapeutic head of the morcellating and aspirating portion 120 (preferably an ultrasonic aspiration blade in this embodiment), and the barrier ring 140 has a small hole for passing the pull wire. The first opening 132 may be pulled through an aperture of the barrier ring 140 via a pull wire 133 into the hollow tubular lumen of the piercing portion 110. In this way, even if some of the tissue debris in the cage 131 leaks from the first opening 132, the barrier ring 140 may further organize the entry of such tissue debris into the body cavity.
Referring to fig. 10, fig. 10 is a schematic structural view of a tissue morcellating suction device having a plurality of baffle rings. In yet another preferred embodiment, a plurality of barrier rings 140 may also be provided between the hollow tubular lumen of the piercing portion 110 and the treatment head tip of the reduction suction portion 120. The first opening 132 can reach between any two barrier rings 140 under traction of the traction wire 133, which ensures better leakage isolation. The blocking ring 140 may be fixedly connected to the hollow tubular cavity of the puncture part 110 or to the tip of the treatment head of the pulverizing suction part.
The second tissue may be liver, uterus, spleen, etc. The comminution suction can be an ultrasonic energy based device or can be another type of device.
