Embodiment 1

[0020] see Figures 1 to 4 , a tubular cutter for obtaining minimally invasive human vein grafts, comprising a cutter head 1, a tunnel tube 2 and a handle 3, the cutter head 1, tunnel tube 2 and handle 3 are connected in sequence, and one end of the tunnel tube 2 is inserted into the knife Inside the head 1, the other end is inserted into the handle 3; the cutter head 1 is a metal cutter head 1, and the cutter head 1 is tubular, that is, a ring-shaped cutter head, and one end of the cutter head 1 is provided with a blade 4, and the The processing of the blade 4 is to thin the end of the tubular cutter head into a blade from the inside to the outside, or from the outside to the inside. Seen from the end face direction of the blade 4, the blade 4 forms a polygon, that is, a multi-faceted blade , the blade 4 is made up of a sharp blade 401 and a blunt blade 402, that is, the sharp blade 401 is a sharper blade, and the blunt blade 402 is a blade that is difficult to cut, and the s...

Embodiment 2

[0023] The difference between this embodiment and Embodiment 1 is that, viewed from the end face direction of the blade 4, the blade 4 is circular, and the blades 4 are all composed of a sharp blade 401, which is easier to cut when the tissue around the vein needs to be cut.

Embodiment 3

[0025] The difference between this embodiment and Embodiment 1 is that, viewed from the end face direction of the blade 4, the blade 4 forms a regular octagon, that is, there are eight sides of the blade 4, the number of sharp blades 401 is four, and the number of blunt blades 402 is four. for four.

[0026] To sum up, using the tubular cutter for minimally invasive harvesting of human vein grafts of the present invention can obtain vein grafts minimally invasively, avoiding huge skin incisions, and the operation is fast, simple, efficient, time-saving and labor-saving, and relatively Greatly reduce medical expenses and reduce discomfort symptoms of patients. The present invention can cut off the peripheral branches of the vein while avoiding long skin incisions and relatively large subcutaneous tissue trauma, and can separate the vein from the surrounding tissue and protect the trunk of the vein graft through the rotary advancement of the tubular cutter. And the main vein is...

Abstract

The invention provides a tubular tool for acquiring a human vein transplant in a minimally invasive manner. The tubular tool comprises a tubular tool bit, a tunnel tube and a handle which are sequentially connected and is characterized in that one end of the tool bit is an edge; the inner wall of the tool bit is provided with an annular protruding part which is close to the side, with the edge, ofthe tool bit. The tubular tool has the advantages that the vein transplant can be acquired in an minimally invasive manner, a large skin cut is avoided, and the tubular tool is fast to operate, simple, practicable, capable of saving time and labor and capable of greatly reducing medical treatment cost and the wound of a patient; a long skin cut and a large subcutaneous tissue wound are avoided, the tubular tool rotates and moves forwardly to separate the vein from peripheral tissue and cut off vein peripheral collateral branches while the main part of the vein transplant is kept intact, the main part of the vein transplant is guided into the tunnel tube, the vein is cut off and the transplant is taken out after required acquiring length is reached, and a minimally invasive effect is guaranteed.

Description

technical field [0001] The invention relates to the technical field of medical tools, in particular to a tubular cutter for minimally invasive human vein graft acquisition. Background technique [0002] Human autologous vein grafts are widely used in bypass or bypass surgery for the treatment of various arterial and venous diseases. Such as coronary artery bypass grafting, lower extremity artery bypass grafting, various visceral artery bypass grafting, superior vena cava resection and great saphenous vein interposition, femorofemoral vein suprapubic bypass, etc. There are currently two ways to obtain a vein graft (usually the great saphenous vein located under the skin on the inside of the leg). One is to cut the skin and cut the vein under direct vision. This method is more conventional and most widely used. The advantage is that the exposure is clear, and the disadvantage is that the trauma is large, and the length of the graft needs to be as long as the skin incision ge...
