Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a laparoscopic splenic pedicle suspension and traction auxiliary device which can increase the exposure space. Background Art

[0002] Laparoscopic surgery requires a small incision in the abdominal wall to allow instruments such as forceps, electric hooks, and a mirror to enter and exit the abdominal cavity. For organs that obstruct the surgical procedure or the field of view, forceps are typically used to lift or compress the organ through the abdominal wall to expose the field of view. Laparoscopic splenectomy, especially for splenomegaly in patients with cirrhosis and portal hypertension, carries a particularly high risk. This is primarily due to the difficulty in exposing the splenic pedicle and its surroundings during surgery. In particular, poor exposure during splenic pedicle manipulation can lead to massive bleeding.

[0003] Patent publication number: CN 202908760 U discloses a laparoscopic spleen traction system that overcomes the difficulty of exposing the splenic pedicle and surrounding areas during surgery. The system comprises a traction cord with a puncture needle fixed to one end and a scalloped cord connected to the other end via a loop. The cord is then attached to a scalloped cuff that secures the spleen. The puncture needle, traction cord, loop, and foldable scalloped cord and cuff are all placed within a traction tube. The spleen can be pulled in all directions for optimal exposure.

[0004] Although the above structure can solve the problem of splenic pedicle exposure to a certain extent, it has the following defects:

[0005] Its structure is that the fan-shaped cord is connected to the fan-shaped edge sleeve for tightening the spleen. The puncture needle, traction rope, ring, and foldable fan-shaped cord and fan-shaped edge sleeve are all placed in the traction tube. During the suspension operation, the required operating space is large and inconvenient.

[0006] Directly suspending the spleen with a cable loop is difficult to control, and the spleen is subject to excessive local force, which may damage the spleen surface. In addition, the spatial exposure is difficult to determine. Simply relying on a traction loop directly applies force, and the operating force needs to be well controlled during the process. At the same time, direct traction is unlikely to achieve maximum exposure.

[0007] Moreover, an auxiliary autologous blood transfusion device is required during the subsequent surgery, which is cumbersome to operate and cannot meet the requirements of use. Utility Model Content

[0008] The purpose of the utility model is to overcome the defects and shortcomings of the existing technology, provide a laparoscopic splenic pedicle suspension and traction auxiliary device with increased exposure space, and solve various problems existing in the existing technology.

[0009] To achieve the above objectives, the present invention provides the following technical solutions:

[0010] A laparoscopic splenic pedicle suspension and traction assistive device for increasing exposure space comprises a splenic pedicle suspension and traction unit and a splenic blood transfusion pressurized airbag for use together. The splenic pedicle suspension and traction unit is at least one group inserted by a laparoscopic puncture sheath. The splenic pedicle suspension and traction unit respectively comprises a metal wire for passing through and enclosing the splenic pedicle blood vessels. One end of the metal wire is a traction end and is connected to a traction belt for suspension. The middle part is bent into a ring shape to form a snare. The other end is a penetration end, which enters through the outside of the spleen until the snare moves to the splenic pedicle. The device also comprises a rubber band for tightening the snare. The rubber band is released through a transfer sleeve assembly sleeved on the metal wire.

[0011] The metal wire is a stainless steel guide wire with a length of 100-130 cm.

[0012] The traction end of the metal wire is provided with a tying ring, and the traction belt is fixed on the tying ring.

[0013] The transfer sleeve assembly includes a metal sleeve, the metal wire traction end and the insertion end are inserted into the metal sleeve together, the front end of the metal sleeve is sleeved with a rubber ring for tightening the snare, and the metal sleeve is provided with a pushing assembly for releasing the rubber ring.

[0014] The pushing assembly includes a push rod, a guide groove is provided on the side wall of the metal sleeve, a push rod is slidably installed in the guide groove, and a sliding button is provided at the rear end of the push rod for easy pushing.

[0015] A limit stopper is provided on the outer side wall of the metal sleeve on one side of the guide groove, a rubber push block is provided at the end of the push rod, a push groove is provided at the front end of the rubber push block, and the longitudinal section of the push groove is trumpet-shaped.

[0016] The spleen blood reinfusion pressurized airbag includes a U-shaped airbag, the inlet and outlet ends of the U-shaped airbag are connected to a press-inflated ball, the inlet and outlet pipes are connected to a one-way valve and an exhaust pipe, and a sealing cap is provided at the outlet of the exhaust pipe.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The present invention has a reasonable structural design. The spleen pedicle suspension traction unit is used to reduce the splenic pedicle while suspending the spleen, thereby increasing the space between the spleen and the abdominal cavity, so as to facilitate the insertion of a laparoscopic closure device to sever the splenic pedicle and remove the spleen in the next surgical operation. At the same time, the operation is convenient. It only requires the insertion of a snare through a laparoscopic puncture sheath, and then the release of the rubber ring by the delivery sleeve assembly for tightening, thereby ensuring stability during the suspension process.

[0019] On the other hand, the splenic blood retransfusion pressurized airbag can be used to return the blood stored in the spleen to the body, while maximally exposing the splenic pedicle and surrounding tissues. This provides a large space for subsequent surgical operations and makes the operation more convenient. In addition, the splenic blood retransfusion pressurized airbag can replace the autologous blood retransfusion device without the need for anticoagulation and filtration, which are complex procedures for strict aseptic operations. It can quickly restore the body's red blood cells and hemoglobin, meeting the requirements of use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See attached Figure 1-7;

[0031] A laparoscopic splenic pedicle suspension and traction auxiliary device for increasing the exposure space includes a splenic pedicle suspension and traction unit 1 and a splenic blood transfusion pressurized air bag for use together. The splenic pedicle suspension and traction unit 1 is at least one group inserted by a laparoscopic puncture sheath. The splenic pedicle suspension and traction unit 1 includes a metal wire 2 for passing through and enclosing the splenic pedicle blood vessels. One end of the metal wire 2 is a traction end and is connected to a traction belt 3 for suspension. The middle part is bent into a ring shape to form a snare 4. The other end is a penetration end. The penetration end enters through the outside of the spleen until the snare 4 moves to the splenic pedicle. It also includes a rubber band 5 for tightening the snare 4. The rubber band 5 is released through a transfer sleeve assembly 6 sleeved on the metal wire 2.

[0032] Furthermore, the metal wire 2 is a stainless steel guide wire with a length of 100-130 cm (of which the metal sleeve portion is approximately 30-40 cm long and the snare portion is approximately 40-50 cm long) and a diameter of approximately 0.014-0.035 inches. A tie ring 7 is provided at the traction end of the metal wire 2, and the traction belt 3 is fixed to the tie ring 7.

[0033] Furthermore, the delivery cannula assembly 6 includes a metal cannula 61, into which the traction and penetration ends of the wire 2 are inserted. The front end of the metal cannula 61 is fitted with a rubber band 5 for securing the snare 4. The metal cannula 61 is also equipped with a pusher assembly for releasing the rubber band. After the wire penetration end passes through the spleen and bends, the metal cannula, with the rubber band at the front end, is inserted from the rear end of the metal cannula to insert the traction and penetration ends of the wire. The pusher assembly is then used to push the wire from the rear end of the metal cannula to the front end of the snare for securement.

[0034] The push assembly further includes a push rod 63. A guide groove 62 is defined in the sidewall of the metal sleeve 61. The push rod 63 is slidably mounted within this guide groove. A sliding button 65 is positioned at the rear end of the push rod 63 for easy pushing. A limit stop 66 is provided on the outer wall of the metal sleeve 61, on one side of the guide groove 62. A rubber push block 67 is positioned at the end of the push rod 63. The front end of the rubber push block 67 defines a push groove 64 with a trumpet-shaped longitudinal cross-section. The limit stop is used to position the sliding button; it can be achieved simply by pushing the rubber ring into place.

[0035] Furthermore, the spleen blood reinfusion pressurized airbag includes a U-shaped airbag 8, the ends of the inlet and outlet air pipes 9 of the U-shaped airbag 8 are connected to a pressing and inflating ball 10, the inlet and outlet air pipes 9 are connected to a one-way valve 11 and an exhaust pipe 12, and a sealing cap is provided at the mouth of the exhaust pipe 12.

[0036] The specific practical process of this application is as follows:

[0037] S1. The snare is inserted through the laparoscopic puncture sheath and passed through the lateral aspect of the spleen to the splenic pedicle.

[0038] S2. The tail end of the wire is connected to a traction belt, and the wire snare is inserted into the splenic pedicle vessels;

[0039] S3. Tighten the snare as much as possible to reduce the splenic pedicle and release the rubber band at the tip through the delivery cannula assembly.

[0040] S4. Repeat step 3 and insert another traction strap.

[0041] S5. Two traction straps are drawn from the two puncture sheaths anterior and posterior to the spleen to suspend the spleen from the abdominal wall for subsequent surgery. After the traction device suspends the spleen from the abdominal wall, a spleen blood transfusion device is used. The steps for its use are as follows:

[0042] (1) Before the spleen blood transfusion device is placed, the splenic artery needs to be clamped with a laparoscopic titanium clip;

[0043] (2) A Y-shaped balloon is placed through the laparoscopic puncture sheath, with the Y arms placed on both sides of the splenic pedicle and the inflated balloon left outside the abdominal cavity;

[0044] (3) Repeatedly press the inflatable ball to inflate the Y-shaped airbag through the one-way valve. When the airbag is full, it compresses the spleen and promotes the return of blood in the spleen to the systemic circulation through the splenic vein;

[0045] (4) Maintain the pressure for about 20 minutes. After the spleen blood is fully transfused, open the vent to release the gas in the air bag.

[0046] (5) Remove the balloon from the puncture sheath and perform surgical operation.

[0047] Although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.

[0048] Therefore, the above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application; that is, all equivalent modifications made according to the scope of the claims of the present application are within the scope of protection of the claims of the present application.
