Abstract
The utility model discloses a miniature scalpel for neurosurgery, which comprises an arc blade, a handle, and a connector connecting the arc blade with the handle, wherein the blade comprises two shape structures including an arc cutting edge and a tooth-shaped cutting edge. The miniature scalpel for neurosurgery has a simple structure, and can effectively solve the problems of inconvenience in cutting and inaccurate positions of different encephalic tissues when implementing intracranial surgeries; meanwhile, the miniature scalpel for neurosurgery is convenient to use, is safe to operate and is more suitable for current intracranial surgeries.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially a kind of neurosurgery Micro operating knife.
Background technology
At present, the scalpel that uses when doing encephalic operation of neurosurgery mostly is the level and smooth cutting edge scalpel of straight formula.In the prior art, when doing encephalic operation, need on skull, to open an aperture earlier, Micro operating knife is probeed into from aperture, relend and help the microscope operation that undergos surgery.Because common Micro operating knife is the level and smooth cutting edge of straight formula, not easily to the incision of intracranial different tissues, and influence the intuitive of surgical field of view, bad control operative site.
When therefore, needing a kind of new neurosurgery Micro operating knife neurosurgery to be carried out encephalic operation with better solution to the inaccurate problem of cutting inconvenience and position of intracranial different tissues.
Summary of the invention
In view of this, this utility model is devoted to better to solve when neurosurgery carried out encephalic operation the inaccurate problem of cutting inconvenience and position of intracranial different tissues, has proposed a kind of neurosurgery Micro operating knife.
The technical solution adopted in the utility model is:
A kind of neurosurgery Micro operating knife comprises cambered blade, handle and connects the connector of cambered blade and handle that wherein, described blade comprises curved edge and two kinds of shape and structures of toothed cutting edge.
Above-mentioned curved edge is arranged on the outer arc limit of cambered blade, and the arc core angle is 30 °～45 °.
Above-mentioned toothed cutting edge is arranged on the inner arc limit of cambered blade.
Above-mentioned handle is provided with embossing hinge stricture of vagina.
Above-mentioned handle end is provided with non-slip process.
The beneficial effects of the utility model are:
This utility model is simple in structure but efficiently solve when neurosurgery carried out encephalic operation the inaccurate problem of cutting inconvenience and position of intracranial different tissues, and simultaneously, handling safety relatively is suitable for existing encephalic operation.
Description of drawings
Below with reference to accompanying drawings specific embodiments of the present utility model is described in detail, wherein:
Fig. 1 is a structure drawing of device of the present utility model;
Wherein, 1-cambered blade, 2-handle, 3-connector, 4-curved edge, 5-toothed cutting edge, 6-non-slip process.
The specific embodiment
To the inaccurate problem of cutting inconvenience and position of intracranial different tissues, this utility model provides a kind of neurosurgery Micro operating knife when in order to solve neurosurgery being carried out encephalic operation.Next specify this neurosurgery Micro operating knife.
Fig. 1 illustrates structure drawing of device of the present utility model.This neurosurgery Micro operating knife comprises cambered blade 1, handle 2 and connects the connector 3 of cambered blade 1 and handle 2, wherein, described cambered blade 1 comprises curved edge 4 and 5 two kinds of shape and structures of toothed cutting edge, can use different cutting edges at different intracranial tissues, make cutting convenient, what be convenient to perform the operation carries out smoothly.
Above-mentioned curved edge 4 is arranged on the outer arc limit of cambered blade 1, and the arc core angle is 30 °～45 °
Above-mentioned toothed cutting edge 5 is arranged on the inner arc limit of cambered blade 1.
Above-mentioned handle 2 is provided with embossing hinge stricture of vagina, and embossing hinge stricture of vagina has antiskid function, safe in utilization when guaranteeing to manage.
