Description

Technical Field

[0001] The invention relates to the technical field of surgical retractors, in particular to a universal surgical retractor for the entire process of kidney transplantation. Background Art

[0002] The kidney transplant process is a complex and delicate process involving many steps, from preoperative preparation to long-term postoperative management. First, the preoperative preparation stage includes a comprehensive assessment of the patient, such as physical examination, laboratory tests, imaging examinations, and psychological assessments to ensure that the patient is suitable for kidney transplantation. Next, the doctor will select a suitable donor kidney based on factors such as the patient's blood type and tissue matching. The acquisition of donors usually includes two situations: living donation and cadaver donation. The kidneys of living donors usually come from relatives or friends, while cadaver donors are kidneys removed as soon as possible after the donor's brain death.

[0003] Surgical retractors are tools commonly used in surgical operations. They are mainly used to separate and fix tissues in order to expose the surgical area. In kidney transplantation, the role of retractors is particularly important because they can help surgeons clearly expose one side of the patient's iliac fossa to ensure that the operation goes smoothly. Kidney transplantation requires an incision of about 10-15 cm in length in the left or right lower abdomen. The doctor needs to carefully separate the abdominal wall muscles, fat, and peritoneum to enter the abdominal cavity and expose the target area for kidney transplantation. During this process, retractors are used to gently pull apart the abdominal tissue to prevent tissue retraction or obstruction, ensuring that the doctor can accurately see the recipient's blood vessels, the location of the kidney implant, and the bladder-urethra connection.

[0004] The surgical retractors in the prior art are usually fixed in an integrated manner, which has some shortcomings in kidney transplant surgery. Since kidney transplant surgery requires a wide area to be exposed and the abdominal anatomical structures of patients vary greatly, the integrated fixed retractors cannot be flexibly adjusted according to specific needs at different stages of the surgery. For example, during the operation, the doctor needs to adjust the position or angle of the retractor according to the different abdominal morphologies of the patient in order to better expose the recipient's blood vessels, kidney implantation site or urethral connection site, but the integrated fixed retractors cannot make such adjustments, resulting in insufficient exposure of some areas or limited field of view, affecting the smooth progress of the operation. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides a universal surgical retractor for the entire process of kidney transplantation, which solves the problem that the surgical retractor in the prior art is usually fixed in an integrated manner, thereby failing to be flexibly adjusted according to the different abdominal shapes of patients.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a universal surgical retractor for kidney transplantation throughout the entire process, comprising a column, an adjustment block is provided on the outer wall of the column through a locking assembly, a support block is fixedly connected to the top of the adjustment block, a half gear is rotatably connected to one side of the support block, a paddle two is rotatably connected to the side of the support block away from the half gear, one end of the paddle two is fixedly connected to a limit plate, the limit plate and the half gear are clamped together, a connecting ring is fixedly connected to the top of the half gear, a retractor piece is provided in the middle of the connecting ring, a clamping assembly is provided on one side of the connecting ring, and the clamping assembly is used to adjust the length of the retractor piece and facilitate the replacement of the retractor piece.

[0007] Preferably, the hook member comprises an adjusting rod, the adjusting rod is slidably connected to the middle part of the connecting ring, and a support member is provided at one end of the adjusting rod.

[0008] Preferably, the locking assembly comprises a fastening screw 1, the fastening screw 1 is threadedly connected to the middle part of the adjusting block, and one end of the fastening screw 1 away from the adjusting block is fixedly connected to a turning handle 1.

[0009] Preferably, a fixing clamp is slidably connected to the outer wall of the column, a fastening screw 2 is threadedly connected to the middle of the fixing clamp, and a rotating rod 2 is fixedly connected to one end of the fastening screw 2 away from the fixing clamp, and the rotating rod 2 is used by the doctor to drive the fastening screw 2 to rotate.

[0010] Preferably, the snap-on assembly includes a paddle 1, which is rotatably connected to one side of the connecting ring, one end of which is fixedly connected to an adjustment plate, one side of the adjustment rod is provided with a plurality of adjustment grooves, and the adjustment plate and the adjustment grooves are snap-connected.

[0011] Preferably, one end of a spring 2 is fixedly connected to one side of the paddle 2, and the other end of the spring 2 is fixedly connected to one side of the support block away from the end of the paddle 2.

[0012] Preferably, one side of the paddle one is fixedly connected to a spring one, and one end of the spring one away from the paddle one is fixedly connected to one side of the connecting ring.

[0013] Preferably, the spreading member comprises a hook, and the hook is connected to one end of the adjusting rod.

[0014] Preferably, the expansion member comprises a pull ring, and the pull ring is connected to one end of the adjustment rod.

[0015] Working principle: When the retractor is used, the fastening screw rod 2 is driven to move by rotating the rotating rod 2. When the fastening screw rod 2 moves, the column can be connected and fixed by the action of the fixing clamp. After the column is connected and fixed, the retractor can be adjusted and used according to different patients.

[0016] When the angle of the retractor is to be adjusted during surgery, one end of the second paddle is manually pressed to squeeze the second spring. When the second paddle squeezes the second spring, it drives the limit plate to move, thereby causing the limit plate to disengage from the half gear. After the limit plate disengages from the half gear, the connecting ring and the half gear are manually driven to move. When the connecting ring moves, it drives the adjusting rod and the retractor to move at the same time, thereby adjusting the angle of the retractor.

[0017] When the hook needs to be extended, one end of the paddle is manually pressed to squeeze the spring. When the paddle squeezes the spring, the adjusting piece is driven to move. When the adjusting piece moves, it will leave the adjusting slot. After the adjusting piece leaves the adjusting slot, the hook can be driven to move and extend through the adjusting rod.

[0018] The present invention provides a universal surgical retractor for the entire process of kidney transplantation. It has the following beneficial effects:

[0019] 1. The present invention presses one end of the second paddle to squeeze the second spring, and the second paddle squeezes the second spring and drives the limiting plate to move, so that the limiting plate is separated from the half gear. When the limiting plate is separated from the half gear, it can easily drive the connecting ring and the adjusting rod to move, and then the angle of the retractor can be conveniently adjusted. At the same time, the retractor can be flexibly adjusted according to different patients, and the overall applicability is increased.

[0020] 2. The present invention squeezes spring one by taking one end of paddle one. When paddle one squeezes spring one, it drives the adjusting piece to move, so that the adjusting piece is separated from the adjusting slot. When the adjusting piece is separated from the adjusting slot, it can easily drive the adjusting rod to move. When the adjusting rod moves, it drives the retractor to move at the same time, so that the position of the retractor can be adjusted conveniently, which makes it convenient for doctors to operate and adjust. At the same time, it makes it convenient for doctors to perform more precise operations and improves the smooth progress of the operation. BRIEF DESCRIPTION OF THE DRAWINGS
