Description
Technical field
This utility model relates to a kind of heart boring operation cutter, belongs to medical surgical knife field.
Background technology
The object of heart punching makes a call to the hole of 1/2 inch, is then connected with artificial heart, does heart and substitute and perform the operation.Existing heart cheesing techniques is fairly simple, opens a cross bore exactly with general scalpel in the position of needs punching, then artificial heart or pipeline is inserted and namely completes.Do like this and the space of inserting artificial heart is not reserved, cause unnecessary heart wall to be squeezed in surrounding or the porch of artificial heart, easily block artificial heart.
Utility model content
The purpose of this utility model is punched to beating heart to solve, and the unnecessary heart wall after punching is cut, and a kind of heart boring operation cutter is proposed, realize not having fifth wheel to get lodged in entrance after the insertion of artificial heart or pipeline, and around artificial heart or pipeline, also do not have too much extruding fever phenomenon occur.
The purpose of this utility model is achieved through the following technical solutions:
A kind of heart boring operation cutter of the present utility model, comprises handle, localizer, boring cutter;
The upper end of localizer is cylinder connection bar, the epimere sidewall of localizer cylinder connection bar is processed with external screw thread, the upper end end face of localizer cylinder connection bar has connecting screw hole downwards, and the lower end of localizer cylinder connection bar is the cross positioning head that cone structure processes;
Have the cylinder of screwed hole centered by boring cutter epimere, the thread segment of this screwed hole and localizer cylinder connection bar matches; The hypomere of boring cutter is thin cylinder, and the lower end of this thin cylinder is processed as the wicker leaf shape blade of discontinuous; The sidewall of boring cutter is processed with annular knurl, facilitates it to rotate;
The upper end of handle is connecting plate, and connecting plate lower face vertically fixes an externally threaded connecting rod of band, and the external screw thread of this connecting rod and the connecting screw hole female thread of localizer cylinder connection bar upper end end face match;
The thin cylinder end of localizer upper end cylinder connection bar from boring cutter is inserted, and make the thread segment threaded engagement of localizer cylinder connection bar enter in the cylindrical screwed hole of boring cutter epimere, the connecting rod screw thread of handle is fixed in the connecting screw hole of localizer cylinder connection bar upper end, and handle and localizer are fixed.
First a cross recess is opened with coventional scalpel at heart tapping during operation, heart is not penetrated, catch the connecting plate of handle, make the cross positioning head insertion heart cross recess of localizer interior and withstand heart, keep handle motionless, rotate boring cutter, boring cutter moves downward along the thread segment spiral of localizer cylinder connection bar, the blade of boring cutter front end cuts heart wall gradually, and makes the heart wall relic cut down be involved in the thin cylinder of boring cutter; Finally solid tool is extracted, insert artificial heart, taken away in the lump at the process heart wall relic extracting cutter.
Beneficial effect
This utility model scalpel structure is simple, easy to operate, can on pulsatile heart is dirty positional punch, and smoothly unnecessary heart wall to be cut down.Compared with existing heart cheesing techniques, be punching complete pulsatile heart is dirty instead of open cross bore and by force artificial heart or pipeline are inserted, be cut heart wall under the state blocked in addition, prevent ventricle inner blood from spraying.Scalpel of the present utility model can be widely used in heart boring operation, also may be used for the medical operation of other organ.

Detailed description of the invention
Below in conjunction with drawings and Examples, content of the present utility model is described further:
Embodiment
A kind of heart boring operation cutter of the present utility model, as shown in Figure 1, comprises handle 1, localizer 3, boring cutter 2;
As shown in Figure 2, the upper end of localizer 3 is cylinder connection bar, the epimere sidewall of localizer 3 cylinder connection bar is processed with external screw thread, the upper end end face of localizer 3 cylinder connection bar has connecting screw hole downwards, and the lower end of localizer 3 cylinder connection bar is the cross positioning head that cone structure processes;
As shown in Figure 3, have the cylinder of screwed hole centered by boring cutter 2 epimere, the thread segment of this screwed hole and localizer 3 cylinder connection bar matches; The hypomere of boring cutter 2 is thin cylinder, and the lower end of this thin cylinder is processed as the wicker leaf shape blade of discontinuous; The sidewall of boring cutter 2 is processed with annular knurl, facilitates it to rotate;
The upper end of handle 1 is connecting plate, and connecting plate lower face vertically fixes an externally threaded connecting rod of band, and the external screw thread of this connecting rod and the connecting screw hole female thread of localizer 3 cylinder connection bar upper end end face match;
The thin cylinder end of localizer 3 upper end cylinder connection bar from boring cutter 2 is inserted, and make the thread segment threaded engagement of localizer 3 cylinder connection bar enter in the cylindrical screwed hole of boring cutter 2 epimere, the connecting rod screw thread of handle 1 is fixed in the connecting screw hole of localizer 3 cylinder connection bar upper end, and handle 1 is fixed with localizer 3.
First a cross recess is opened with coventional scalpel at heart tapping during operation, heart is not penetrated, catch the connecting plate of handle 1, make the cross positioning head insertion heart cross recess of localizer 3 interior and withstand heart, keep handle 1 motionless, rotate boring cutter 2, boring cutter 2 moves downward along the thread segment spiral of localizer 3 cylinder connection bar, the blade of boring cutter 2 front end cuts heart wall gradually, and makes the heart wall relic cut down be involved in the thin cylinder of boring cutter 2; Finally solid tool is extracted, insert artificial heart, taken away in the lump at the process heart wall relic extracting cutter.
