Technical Field
The invention relates to the field of medical instruments, in particular to a novel hepatic portal blocking belt.
Background
Nowadays, with the rapid development of medical technology, the current liver tumor treatment scheme is developed from traditional liver surgery treatment to multidisciplinary comprehensive treatment, but the preferred scheme for treating liver tumor is liver surgery, and the key point for safely implementing hepatectomy is to control the blood flow of liver.
Nowadays, with the rapid development of medical technology, the current treatment scheme for liver tumor and intrahepatic bile duct calculi is developed from traditional liver surgery to multidisciplinary comprehensive treatment, but the preferred scheme for treating liver tumor is liver surgery, and the key for safely implementing hepatectomy is to control the blood flow of liver. Therefore, two major problems encountered in liver surgery are how to safely and effectively control intraoperative hemorrhage and prevent postoperative liver function, and reduce postoperative complications.
During surgery, surgeons need to carefully control the amount of bleeding in patients, and therefore, a variety of hemostatic methods have evolved, again the most common of which is Pringle maneuver. The pilgerg hemostasis method is commonly applied to laparoscopic surgery, such as liver surgery, and generally, the traditional operation method is to take three hepatic ducts out and then clamp them with hemostatic forceps to restrict the blood flow of hepatic artery and portal vein. Therefore, in order to prevent the liver from being damaged due to the long ischemia time, the blood flow restriction area needs to be released at proper time during the operation process to circulate the blood flow to the viscera again, however, the repeated hemostasis process is complicated and time-consuming, and the hepatic valve tritubular structure needs to be distinguished again to restrict the blood flow during each hemostasis process.
At present, the traditional surgical method is gradually replaced by laparoscopic surgery, and becomes the mainstream trend of the current main surgery, the main surgical method has the advantages that the wound of the gastric surgery is smaller, the infection risk of a patient can be reduced, and the recovery period of the patient is shortened; furthermore, laparoscopic surgery allows much of the dead space in the abdominal cavity, e.g., the right posterior lobe and the deep left liver, to be seen more clearly than conventional surgery. In addition to requiring a better field of view for laparoscopic surgery, the need for appropriate access holes for placement of camera lenses and related surgical instruments directly affects the smoothness of the surgery.
Therefore, when the traditional pilger hemostasis method is applied to laparoscopic surgery, a plurality of limitations are caused, and the vicker is placed into a hemostatic forceps, an operation hole is additionally arranged on the abdomen of a patient, so that the wound of the abdominal wall of the patient is increased; moreover, the operation space of the laparoscope is limited, and the operation space is limited conventionally; in addition, since intermittent hemostasis is required until the surgery is completed in the surgery process, it is more inconvenient to apply the traditional tedious and time-consuming method to laparoscopic surgery.
In view of the above, there is a need in the art for an improved temporary blocking device for blood flow, which is used to improve or help restrict the blood flow in the organs during the current abdominal surgery.
Please refer to fig. 1, chinese utility model patent publication No. CN201320221559.8 discloses a hepatic portal blood flow blocking belt, which comprises a blocking belt main body with uniformly distributed dentate protrusions, and a belt threading tube connected with the blocking belt main body, wherein the blocking belt main body is movably connected with the belt threading tube through a belt.
The portal blood flow blocking tape of the prior art has the following disadvantages: 1. the tape threading tube is not hard, so that deformation is easy to occur, and the connection is not fixed. 2. In the process of connecting the blocking belt main body and the belt penetrating cylinder, the blocking belt main body firstly penetrates the belt penetrating cylinder, and the blocking belt main body is fixed only through friction force, so that the slow displacement condition exists, and the fixing effect is influenced. 3. The blocking band surrounds the portal annularly, but the central position of the portal is not easy to seal.

An arc surface is arranged between the limiting groove 4 and the through hole 3 and used for reducing the abrasion of the fixing band 2.
The through hole 3 is oval, and the long wheelbase of the through hole 3 is twice or more than twice of the short wheelbase. The diameter of the adjusting section 22 is smaller than the short wheelbase of the through hole 3.
The fixing strap 2 comprises a connecting section 21 connected with the fixing plate 1, an adjusting section 22 and an inserting section 23, the connecting section 21 penetrates through the through hole 3 to be hinged with the fixing plate 1, and the connecting section 21 can also be integrally formed with the fixing plate 1. The end of the insertion section 23 facing away from the adjustment section 22 tapers off, and the through-opening 3 is greater than or equal to the maximum diameter of the adjustment section 22.
The adjusting section 22 is used for adjusting the tightness, and the adjusting section 22 is provided with scale marks 26. The distance between adjacent graduation marks 26 is 1cm, and the graduation mark 26 at a distance of 5cm from the connecting section 21 is thickened. The tightness degree of the fixing belt 2 is judged by controlling the position of the scale marks 26. The diameter of the fixing band 2 can be changed by stretching.
One side that fixed plate 1 is located spacing groove 4 is equipped with a plurality of archs 11 that are used for increasing frictional force, and in the use, use vascular pincers or chamber mirror nipper to press from both sides and get fixed plate 1 more, and a plurality of archs 11 then play the effect of stably grabbing and holding. The fixing plate 1 is made of hard plastic, the fixing band 2 is made of flexible rubber or silica gel, and the fixing band 2 is a solid latex or silica gel band.
Referring to fig. 3, the novel portal blocking belt is used to control the blood flow rate and blood flow switch of portal 5. The limiting ring 24 also has the function of controlling the tightness, and the number of the limiting rings 24 above the limiting groove 4 is observed, so that the compression force on the porta hepatis 5 is judged.
In the using process, firstly, the hepatic portal 5 is found out, then the fixing plate 1 is attached to one side of the hepatic portal 5, and then the insertion section 23 of the fixing band 2 bypasses the hepatic portal 5 and passes through the through hole 3 to enable the hepatic portal 5 to be positioned between the fixing band 2 and the fixing plate 1; then the fixing band 2 is tightened by pulling the insertion section 23 from the other side, at this time, the diameter of the fixing band 2 becomes smaller and the elasticity becomes lower after being stretched, and the hepatic portal 5 is also pressed and narrowed; finally, the adjusting section 22 of the fixing band 2 is moved into the limiting groove 4 and loosened, at this time, the fixing band 2 above the limiting groove 4 is restored, and the fixing band 2 in the limiting groove 4 and between the limiting groove 4 and the connecting section 21 is still in a stretched state, so that the fixing band 2 always presses the hepatic portal 5, and the hepatic portal 5 stops blood supply or reduces blood supply.
When the fixation is released, the fixing plate 1 is fixed, the fixing belt 2 is tightened, and the fixing belt 2 moves back to the through hole 3, so that the fixation is conveniently released.
When the fixed hepatic portal 5 of area is blocked to this hepatic portal, the regulation section 22 that is located limiting groove 4 and limiting groove 4 top keeps great frictional force with this fixed plate 1 to guarantee the fastening to fixed band 2, prevent the phenomenon of contracting.
Referring to fig. 4 and 5, in the second embodiment of the present invention, the adjusting section 22 is provided with a plurality of position-limiting rings 24, the position-limiting rings 24 have guiding surfaces 25 inclined toward the connecting section 21, and the guiding surfaces 25 are used for facilitating the passing of the adjusting section 22 through the through hole 3. The distances between the adjacent limiting rings 24 are the same, and the tightness degree of the fixing band 2 is judged by controlling the positions of the limiting rings 24. The distance between adjacent stop collars 24 may be varied by stretching. When the adjustment segment 22 is stretched to the maximum length, the diameter of the stop collar 24 is greater than the width of the stop slot 4.
When fixing the hepatic portal 5, the limiting ring 24 is located above the limiting groove 4 and limits the adjusting section 22 to move below the limiting groove 4, so that the hepatic portal 5 is better blocked, and the oppression on the hepatic portal 5 is prevented from being relieved or reduced. When the fixation is released, the fixation band 2 needs to move back to the through hole 3, and the fixation can be released.
Compared with the first embodiment, the present embodiment adds a position limiting function by the position limiting ring 24, thereby better blocking blood flow.
Referring to fig. 6, in a third embodiment of the present invention, the limiting groove 4 is provided with a plurality of mutually staggered limiting strips 41, the limiting portion is a latch, and the cross section of the limiting portion is triangular or rectangular. When fixing the hepatic portal 5, the fixing band 2 in the limiting groove 4 has a larger contact area with the limiting groove 4, thereby increasing the friction force and preventing the occurrence of looseness.
Referring to fig. 7, in a fourth embodiment of the present invention, a pair of limiting protrusions are disposed in the middle of the through hole, so as to prevent the connecting section 21 from sliding left and right.
Referring to fig. 8, in a fifth embodiment of the present invention, a pair of pressing strips 12 is disposed on one or both surfaces of the fixing plate 1, and the length of the pressing strips 12 is not less than the sum of the lengths of the through holes 3 and the limiting grooves 4. When the portal 5 is fixed, the pair of compression bars 12 bends both sides of the compressed portal 5, thereby further enhancing the flow blocking effect on the portal 5.
Referring to fig. 9, in a sixth embodiment of the present invention, a fixing plate 1 is provided with a fixing hole 13, and a connecting section 21 passes through the fixing hole 13 and is hinged to the fixing plate 1. The fixing band 2 is fixedly connected with the fixing plate 1 through the fixing hole 13, so that the insertion section 23 is prevented from contacting the connection section 21 when being inserted into the through hole 3, thereby facilitating the extraction of the insertion section 23 from the other side.
In the present invention, when the adjustment section 22 is stretched to the maximum length, the diameter of the stop collar 24 is greater than the width of the stop groove 4, and the stop collar prevents the adjustment section from moving, thereby preventing slow movement caused by fixation only by friction.
In the invention, the fixing plate 1 is made of hard plastic, so that the blocking belt reduces the situation that the sealing cannot be carried out due to the change of the blood pressure in the liver, and the sealing effect is enhanced.
In the invention, the limiting groove 4 is provided with a plurality of limiting strips 41, so that the friction force between the limiting groove and the adjusting section is enhanced, and the blood flow blocking effect is improved.
