Abstract
The utility model provides a but vascular by -pass operation tunnel ware around musical form. But operation tunnel ware is equipped with the base in the one end of curved bar, is equipped with the handle on the base, but that the other end of curved bar is opened is threaded, and the tip that the front portion of screw can the curved bar is equipped with the fixed drawing head of blood vessel, but during the curved bar embolias tunnel ware sheathed tube sleeve pipe through -hole, during the fixed drawing head of blood vessel embolias the fixed head hole on the cone, but and the cone be connected with the curved bar through the screw. Bypass blood vessel tunnel is establish to this tunnel ware in the operation, make bypass blood line not receive extrusion, distortion or damage, and simple structure, convenient operation.
Description
Technical field
This utility model relates to medical instruments field, and being related specifically to one can musical form peripheral vessels by-pass operation tunneler.
Background technology
Peripheral vessels by-pass operation is vascular surgery common surgical, can use autologous or artificial blood vessel in by-pass operation.In operation, autologous or artificial blood vessel to be arrived distal anastomosis port part by proximal anastomosis mouth through certain interstice or structure, and prior art uses conventional clamp carry out drag operation, and this operation is greatly likely to result in vascular bypass distortion, oppresses or damage.Therefore the tunneler exclusively for peripheral vessels by-pass operation design specialist it is badly in need of.
Summary of the invention
The purpose of this utility model be to provide one utilize conical head, blood vessel fixed traction head, can curved bar and tunneler sleeve pipe, make the damaged less of vascular bypass in operation can musical form peripheral vessels by-pass operation tunneler.
For achieving the above object, the technical solution of the utility model is:
One can musical form peripheral vessels by-pass operation tunneler, including conical head, blood vessel fixed traction head, screw thread, can curved bar, base, handle and tunneler sleeve pipe, described tunnel surgery device can one end of curved bar equipped with base, equipped with handle on base, the other end of curved bar can have screw thread, the front portion of screw thread gets final product the end of curved bar equipped with blood vessel fixed traction head, can be inserted in the sleeve through hole of tunneler sleeve pipe by curved bar, blood vessel fixed traction headgear enters in the fixing head bore on conical head, and conical head by screw thread with can be connected by curved bar.
Good effect of the present utility model is:
1, this tunneler sets up vascular bypass tunnel in operation, makes that bypass bloody path is not compact, distorts or damage；
2, this tunneler simple in construction, easy to operate；
3, use this tunneler can alleviate the misery in patient's operation, and procedure can be greatly speeded up.

Fig. 1, can musical form peripheral vessels by-pass operation tunneler structural representation；
Fig. 2, conical head structural representation；
Fig. 3, can bending staff design schematic diagram；
Fig. 4, vessel cannula structural representation.
Detailed description of the invention
1-4 further illustrates detailed description of the invention of the present utility model below in conjunction with the accompanying drawings.
nullSee accompanying drawing 1-4，By the tunnel surgery device foundation operative site assembled and the shape of vascular bypass，It is pre-bent to required camber in vitro，Again by between proximal anastomosis otch and distal anastomosis otch，Tunnel surgery device is penetrated and plans to build vertical subcutaneously or intramuscularly passage，When conical head 1 passes from far-end otch (or proximal end otch)，Conical head 1 is taken away from can screw off at the screw thread 3 on curved bar 4，Make to expose from fixing head bore 8 the blood vessel fixed traction head 2 of curved bar 4 end，Then artificial blood vessel or autologous vein are inserted on blood vessel fixed traction head 2，And the groove between blood vessel fixed traction head 2 and screw thread 3 fixes，After completing，Tunneler sleeve pipe 7 is fixed in the passage set up，And hold the handle 6 being contained on base 5，Pulling out can curved bar 4，Make artificial blood vessel or autologous vein can under the pulling of curved bar 4 traveling in sleeve through hole 9，When one end of sleeve through hole 9 is exposed in the end of artificial blood vessel or autologous vein，By artificial blood vessel or autologous vein from taking off curved bar 4，After fixing side artificial blood vessel or autologous vein，Tunneler sleeve pipe 7 is extracted out，Then vascular anastomosis process is carried out，After being disposed，Each element purge after finally using、Re-assembly，Terminal disinfection encapsulation is standby.
