Description

Technical Field

[0001] The invention relates to the field of medical instruments, and in particular to a non-destructive vein blocking clamp used for organ transplantation. Background Art

[0002] Transplantation refers to the technology of introducing a cell, tissue or organ of an individual into a part of the body or another individual by surgery or other methods to replace the lost function. In the process of organ transplantation, due to the complexity of the surgical procedure, many blood vessels and nerves are involved. In order to prevent the large amount of blood flow in the blood vessels from affecting the operation, it is necessary to clamp the blood vessels during the operation to block their flow. In the existing operation, hemostatic forceps are usually used for clamping, and when the hemostatic forceps are used, the long handle of the forceps still stands upright beside the surgical incision, affecting the surgical operation, and is easily touched by the surgical staff, causing potential tissue damage. In addition, many venous blood vessels need to be involved. The venous blood vessels are relatively fragile and there are more of them. If the hemostatic forceps are used, it is easy to damage the venous blood vessels, and a lot of hemostatic forceps need to be used, which is very troublesome to operate. In addition, some veins are in some hidden places, and the use of hemostatic forceps is easy to be lost.

[0003] In order to solve the above problems, Chinese patent document CN201910654056.1 discloses a non-destructive venous blocking clamp for organ transplantation, including a shell, an operating window, a shock-absorbing pad, a blocking block, a fixed splint, a protective pad, an extrusion groove, a fluorescent strip, a positioning block, a connecting rod, a movable splint, an extrusion strip, a slide, an operating button, a spring bump, a power spring, a protective cover, a connecting hole, a sealing cover and a slide groove. The beneficial effects of the present invention are as follows: the protective pad and the movable splint are in the shape of circular arcs that can mesh with each other and both are made of soft materials. The circular arc structure can clamp multiple veins at a time, and the material is soft and will not hurt the blood vessels. The extrusion strip protrudes from the surface of the movable splint and matches the concave shape of the extrusion groove, which can effectively clamp the veins and play a good blocking effect on the veins. Two symmetrical spring protrusions with power springs are fixed on the rear end face of the slide, so that the elastic force on the slide is more uniform and the slide is not easy to shift. However, in actual operation, since the blood vessels have a certain elasticity and the clamping force is provided by the power spring, this leads to the need to select a power spring with appropriate elasticity for different blood vessels. Otherwise, it is easy to cause the blood vessels to fall off due to insufficient clamping or to damage the blood vessels due to excessive clamping, which makes it difficult to implement in actual operation.

[0004] Chinese patent document CN202110220185.7 also discloses a non-destructive vein blocking clamp for organ transplantation, which includes a clamp body, a rotating handle is provided on one side of the clamp body, a first rotating shaft is fixedly connected to one side of the rotating handle, one end of the first rotating shaft passes through one side of the clamp body and extends to the inside of the clamp body, two first driving wheels are fixedly connected to the outer wall of the first rotating shaft, and the second rotating shaft is rotatably connected to both sides of the inside of the clamp body, and the first driven wheel is fixedly connected to one side of the outer wall of the two second rotating shafts. The present invention facilitates the use of the clamp body by sliding two first clamp blocks and two second clamp blocks, and avoids the phenomenon of the clamp body falling off and not clamping tightly by setting the first clamp block and the second clamp block. The travel switch is triggered to light up the lamp body while clamping the two first clamp blocks and the two second clamp blocks, and the lamp body is lit up to remind medical staff, avoid the phenomenon of the clamp body being left out of the human body, and is convenient for medical staff to use; although the above scheme can avoid the problem of not clamping tightly, the structure is too complicated, the use cost is too high, and it is not convenient to implement during surgery.

[0005] The above problems seriously affect the blocking effect of venous blood vessels in organ transplantation surgery, making the operation process more complicated and may even cause serious medical accidents due to poor blocking effect.

[0006] Therefore, there is an urgent need for a non-destructive venous blocking clamp for organ transplantation that can solve the problems of existing venous blocking clamps that the clamping force is difficult to adjust and the structure is too complicated, making them inconvenient to use in surgery.
