Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of instrument for excising veinous valve.
Background technology
At present, in vascular surgery, after the long section of human body lower limbs tremulous pulse obturation, the patient is imposed long section vein coronary artery bypass grafting below knee joint, can remove symptom and save limbs.At present traditional that the inaccessible patient of the long section of artery of lower extremity is imposed original position vein valve resection operation success rate is very low, and operative site is darker, and exposure of surgical field is difficulty comparatively.
The utility model content
For the problems referred to above, the technical problem that this utility model solves is to provide a kind of instrument for excising veinous valve.
The technical solution of the utility model is: a kind of instrument for excising veinous valve, comprise rubber column, the rubber column end is provided with circular blade, there is traction fiber at the rubber column center, traction fiber passes the second rubber column attended operation handle, clamping Connection Block on operating grip, Connection Block is connected with the magnifier bearing by hinge, and the magnifier bearing is provided with magnifier.
The beneficial effects of the utility model are: simple in structure, easy to operate, can safety and precise complete the vein valve resection operation.
The beneficial effects of the utility model are: simple in structure, easy to operate, can safety and precise complete the vein valve resection operation.
Description of drawings
Fig. 1 is this utility model structural representation.
The specific embodiment
As shown in the figure, plant instrument for excising veinous valve, comprise rubber column 1, the rubber column end is provided with circular blade 2, there is traction fiber 3 at the rubber column center, and traction fiber passes the second rubber column 4 attended operation handles 5, clamping Connection Block 6 on operating grip, Connection Block is connected with magnifier bearing 8 by hinge 7, and the magnifier bearing is provided with magnifier 9.During operation, first at superficial vein one end-grain cutting one osculum, pull hinge and adjust the corner dimension of magnifier bearing and Connection Block, thereby suitable position is adjusted in the position of magnifier, observe by magnifier, rubber column is inserted vein in advance, then insert successively the second rubber column, by flexible traction filament, after entirely being entered the vein certain depth, rubber column and the second rubber column reclaim again.In removal process, in the effect of the circular blade of rubber column end, with the excision of the valve on wall of vein, the second rubber column can support and protect blood vessel, avoids blood vessel by scratch.
