Abstract
The utility model relates to a special centre gripping of neural blood capillary decompression operation tweezers, including tweezers handle, connecting rod and exposed core, the exposed core comprises changeover portion and operation section, is tadpole shape, and operation section width is greater than the changeover portion width. Tadpole shape exposed core is convenient for operate, not only can get the felt piece by the steadying bracket, avoids touching the extrusion nerve in addition, and the in -process of avoiding performing the operation leads to the fact the neurotrosis.
Description
Technical field
This utility model relates to a kind of neural minimal vessel count Special clamping tweezer, belongs to technical field of medical equipment.
Background technology
Trigeminal neuralgia and facial spasm are two kinds of common nervous system disease, and the maximally effective operation method generally acknowledged the most in the world is neural Microvascular decompression, are also the operation methods that functional neurosurgery surgery is conventional.The committed step of operation i.e. places one at abnormal vascular exactly between compressing vessels and nerve can play the politef cotton that " insulation " acts on, and releases abnormal vascular to neural compressing with this.Owing to this operation belongs to Minimally Invasive Surgery, bone window typically only has 2.5 3 cm diameter sizes, operates in art under surgical microscope, and action must be soft, is otherwise easy to injured nerve blood vessel.In actual mechanical process; owing to most of abnormal vasculars are all located at the veutro of nerve; the overall picture of blood vessel is often can't see under direct-view; so it is straight for using conventional gun-shaped forceps front end; the when of placing felt piece; often touching extruding nerve, operating is not the most smoothly, causes nerve injury unavoidably.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of neural minimal vessel count Special clamping tweezer, bare terminal end is tadpole-shaped and bare terminal end inner side end is provided with rubbing surface, not only can conveniently operate, it is to avoid touch extruding nerve, and rubbing surface is easy to clamp politef cotton, prevents from coming off.
For solving problem above, concrete technical scheme of the present utility model is as follows: a kind of neural minimal vessel count Special clamping tweezer, and including tweezer handle, connecting rod and bare terminal end, bare terminal end is made up of changeover portion and lever piece, in tadpole-shaped, lever piece width is more than transition width.Tadpole-shaped bare terminal end is convenient to operate, not only can stably grip felt piece, and avoid touching extruding nerve, unavoidably cause nerve injury in operation process.
The medial surface of described bare terminal end is provided with protruding rubbing surface.
Described lever piece cross section is oval, and changeover portion is arc.
Described changeover portion is minor arc.
What this utility model brought have the beneficial effect that bare terminal end is tadpole-shaped and bare terminal end inner side end are provided with rubbing surface, not only can conveniently operate, it is to avoid touch extruding nerve, and rubbing surface to be easy to clamp politef cotton, prevent from coming off.
Accompanying drawing explanation
Fig. 1 is the structural representation of neural minimal vessel count Special clamping tweezer.
Fig. 2 is the profile of bare terminal end.
Wherein, 1-bare terminal end, 2-connecting rod, 3-tweezer handle, 4-lever piece, 5-rubbing surface, 6-changeover portion.
Detailed description of the invention
As depicted in figs. 1 and 2, a kind of neural minimal vessel count Special clamping tweezer, including tweezer handle 3, connecting rod 2 and bare terminal end 1, bare terminal end 1 is made up of changeover portion 6 and lever piece 4, and in tadpole-shaped, lever piece 4 width is more than changeover portion 6 width.Tadpole-shaped bare terminal end is convenient to operate, not only can stably grip felt piece, and avoid touching extruding nerve, it is to avoid cause nerve injury in operation process.
The medial surface of described bare terminal end 1 is provided with protruding rubbing surface 5.
Horizontal 4 cross sections of described lever piece are oval, and changeover portion 6 is arc.
Described changeover portion 6 is minor arc.
Operator holds tweezer handle 3 and connecting rod 2, controls connecting rod 2 folding, connecting rod 2 opening gripping felt piece, close connecting rod 2 after gripping, bare terminal end 1 is put between nerve and blood vessel, felt piece is put between nerve and blood vessel by neural and blood vessel side, complete backed off after random clamping forceps, complete operation.
Above-described is only preferred embodiment of the present utility model.It should be pointed out that, for the person of ordinary skill of the art, on the premise of without departing from this utility model principle, it is also possible to make some modification and improvement, also should be regarded as belonging to protection domain of the present utility model.
