Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to an isolation support device used in laparoscopic surgery. Background Technology

[0002] Minimally invasive surgery has become a trend in surgical development, with laparoscopic surgery taking the lead, enabling almost all surgical procedures to be minimally invasive. In particular, when performing laparoscopic resection of liver and kidney tumors, it is necessary to elevate the liver and kidneys to expand the surgical field.

[0003] The laparoscopic surgical support device disclosed in the utility model with authorization announcement number CN209548022U includes an air bladder, a one-way valve, and an inflation tube. The inflation tube has an inlet end and an outlet end. The outlet end of the inflation tube is detachably connected to the inlet end of the one-way valve, and the outlet end of the one-way valve is connected to the air bladder. The outlet end of the inflation tube and the inlet end of the one-way valve are detachably connected by a connector. The connector includes a joint and a sleeve that mates with the joint. An air delivery channel is formed inside the joint. The joint and the sleeve are respectively located at the outlet end of the inflation tube and the inlet end of the one-way valve. This solution has the advantages of simple structure, low manufacturing cost, and the ability to disassemble and assemble the inflation tube, thus avoiding the occupation of surgical space.

[0004] However, the above technical solutions have the following shortcomings: because the airbag is relatively soft, it is easy to deform during placement and cannot be accurately moved to the lower side of the liver and kidney. At the same time, it cannot provide stable load-bearing force during the load-bearing process, which can easily cause the liver and kidney to shift, affecting the operation. Furthermore, the use of instruments during the operation can easily cause the airbag to rupture, affecting its use. Therefore, we propose an isolation support device for use in laparoscopic surgery. Utility Model Content

[0005] The purpose of this invention is to provide an isolation support device for laparoscopic surgery, in order to solve the problems mentioned in the background art, which are that the overall softness of the airbag makes it easy to deform during placement, making it impossible to move it accurately to the lower side of the liver and kidneys.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1-4 The present invention provides a technical solution: an isolation support device used in laparoscopic surgery, including a support part 1, the support part 1 being a hollow vertebral structure, the support part 1 being mounted on a base plate 5, due to the vertebral structure, the device can be placed on the lower side of the liver or kidney and smoothly moved to the lifting pad 21, the support part 1 being provided with an installation port 6 in the middle, the installation port 6 being provided with a lifting structure 2 that provides continuous support for the liver or kidney;

[0034] The lifting structure 2 includes a lifting pad 21, which is installed in the mounting port 6. An adjustment component for lifting the lifting pad 21 is installed on the chassis 5. The adjustment component includes a ball screw 232, which is rotatably mounted in a mounting frame 231. The mounting frame 231 is mounted on the chassis 5. A nut seat 233 is installed on the ball screw 232. The nut seat 233 is connected to the lifting pad 21 through a scissor-fork linkage structure 23. The rotation of the ball screw 232 can drive the nut seat 233 to move.

[0035] Specifically, the scissor-type linkage structure 23 includes a first linkage 237 and a second linkage 238. The first linkage 237 and the second linkage 238 are arranged crosswise, and the first linkage 237 and the second linkage 238 are rotatably connected at the middle. The two ends of the first linkage 237 are rotatably connected to the first upper ear seat 235 and the first lower ear seat 240, respectively. The first upper ear seat 235 is movably disposed on one side of the bottom of the lifting pad 21, and the first lower ear seat 240 is disposed on the platform 241, which is disposed on the chassis 5. By rotating the first linkage 237 and the second linkage 238 in opposite directions, the lifting pad 21 can be moved, and the height of the lifting pad 21 can be adjusted. At the same time, the lifting height is positioned, and the load-bearing stability is good.

[0036] Specifically, the two ends of the second connecting rod 238 are rotatably connected to the second upper ear seat 239 and the second lower ear seat 234, respectively. The second upper ear seat 239 is located on the other side of the bottom of the lifting pad 21, and the second lower ear seat 234 is located on the nut seat 233. By moving the nut seat 233, the second lower ear seat 234 can be moved, thereby causing the second connecting rod 238 to rotate and perform a lifting action.

[0037] First, the device is placed under the liver or kidney. The rotating structure 3 drives the ball screw 232 to rotate, which in turn drives the screw nut 233 to move. The movement of the screw nut 233 drives the second lower ear seat 234 to rotate, which in turn drives the second connecting rod 238 to rotate within the second lower ear seat 234 and the second upper ear seat 239. The second connecting rod 238 drives the first connecting rod 237 to rotate, which in turn rotates within the first lower ear seat 240 and the first upper ear seat 235. The first upper ear seat 235 moves, and the height of the lifting pad 21 is adjusted by the cross rotation of the first connecting rod 237 and the second connecting rod 238. The lifting pad 21 adjusts the height of the liver or kidney, increasing the surgical field and can also be used for intraoperative isolation of the liver or kidney. The lifting pad 21 ensures the stability of the load-bearing capacity.

[0038] Furthermore, the upper surface of the lifting pad 21 is also provided with an arc-shaped groove 22 to further enhance the stability of the liver or kidney support, while also enabling the collection of fluids.

[0039] Furthermore, a limiting slider 236 is also provided on the first upper ear seat 235. The limiting slider 236 is slidably disposed in the limiting groove 26, which is disposed at the bottom of the lifting pad 21. When the first connecting rod 237 and the second connecting rod 238 rotate in opposite directions to lift the pad, the first connecting rod 237 drives the first upper ear seat 235 to move, and the first upper ear seat 235 drives the limiting slider 236 to move within the limiting groove 26, thereby improving the guiding performance of the first upper ear seat 235 during movement.

[0040] Furthermore, a sealing ring 27 is provided on the outer surface of the lifting pad 21, and the sealing ring 27 fits against the inner wall of the mounting port 6.

[0041] Furthermore, a guide slider 25 is provided at the bottom of the nut seat 233. One end of the guide slider 25 is slidably disposed in the guide groove 24, which is disposed on the chassis 5. When the nut seat 233 moves, it drives the guide slider 25 to move within the guide groove 24, thereby improving the guiding performance of the nut seat 233 during movement.

[0042] Furthermore, a sealing ring 27 is provided on the outer surface of the lifting pad 21. The sealing ring 27 fits against the inner wall of the mounting port 6, which can ensure the sealing of the mounting port 6 when the height of the lifting pad 21 is adjusted, thus preventing liquid from entering the support part 1.

[0043] As a specific embodiment of this application, please refer to Figure 2 and Figure 5 The support part 1 is also provided with a rotating structure 3, which includes an adjustment knob 31. The adjustment knob 31 is rotated and set in a hole 37. The hole 37 is set on one side of the support part 1. A main bevel gear 33 is set at one end of the adjustment knob 31. The main bevel gear 33 meshes with a secondary bevel gear 34. The secondary bevel gear 34 is set at one end of the ball screw 232. A cross-shaped groove 36 is set on the adjustment knob 31. A drive structure 4 can be detachably installed in the cross-shaped groove 36.

[0044] Rotating the adjustment knob 31 causes the main bevel gear 33 to rotate, which in turn drives the auxiliary bevel gear 34 to drill a hole. Through the transmission between the main bevel gear 33 and the auxiliary bevel gear 34, the rotation direction of the ball screw 232 can be controlled, and the support height of the lifting pad 21 can be adjusted.

[0045] Furthermore, an annular slider 32 is provided on the outer surface of the adjustment knob 31. The annular slider 32 is slidably disposed in the annular groove 35, which is disposed in the hole 37. The rotation of the adjustment knob 31 drives the annular slider 32 to rotate in the annular groove 35, thereby improving the stability of the adjustment knob 31 when it rotates.

[0046] As a specific embodiment of this application, please refer to Figure 6 The drive structure 4 includes a cross-shaped locking block 42, which is disposed at one end of the gripping rod 41.

[0047] When it is necessary to rotate the adjustment knob 31, insert the cross-shaped locking block 42 into the cross-shaped locking slot 36, rotate the grip rod 41, and the grip rod 41 drives the adjustment knob 31 to rotate through the cross-shaped locking block 42. After the height of the lifting pad 21 is adjusted, separate the cross-shaped locking block 42 from the cross-shaped locking slot 36 and remove the grip rod 41. This makes it easy to drive the adjustment knob 31 to rotate, and it is also detachable so as not to obstruct the surgical field of vision.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
