Abstract
The utility model discloses a novel neurosurgery minitype surgical knife which comprises an arc-shaped blade provided with an arc-shaped cutting edge and a tooth-shaped cutting edge, a handle and a connecting piece used for connecting the arc-shaped blade with the handle, wherein the handle is an elliptical ring handle. The novel neurosurgery minitype surgical knife disclosed by the utility model is simple in structure, can be used for solving the problems that the surgical knife is not easy to master and easy to slid off from a hand during a neurosurgery operation, simultaneously is safe to operate and is more suitable for the existing neurosurgery operation.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially a kind of novel neurosurgery Micro operating knife.
Background technology
At present, mostly the scalpel that when doing encephalic operation, uses of neurosurgery 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 handle be not provided with any safeguard procedures that scalpel is slippage from operator's hands easily, thereby causes malpractice.
The problem of scalpel easy master and difficult slippage from hands when therefore, needing a kind of new novel neurosurgery Micro operating knife neurosurgery to be undergone surgery with better solution.
Summary of the invention
In view of this, this utility model is devoted to better to solve scalpel easy master when neurosurgery undergone surgery and is difficult for the problem of slippage from hands, has proposed a kind of novel neurosurgery Micro operating knife.
The technical scheme that this utility model adopts is:
A kind of novel neurosurgery Micro operating knife comprises cambered blade, the handle that is provided with curved edge and toothed cutting edge and is connected cambered blade and the connector of handle that wherein, said handle is the oval ring handle.
Above-mentioned curved edge is arranged on the outer arc limit of cambered blade, and the arc core angle is 15 °～25 °.
Above-mentioned toothed cutting edge is arranged on the inner arc limit of cambered blade.
The major radius of above-mentioned oval ring handle is 2: 1 with the ratio of short radius.
Above-mentioned connector is 1: 1～2: 1 with the ratio of oval ring handle major radius.
The beneficial effect of this utility model is:
This utility model is simple in structure but efficiently solve the problem that scalpel when neurosurgery undergone surgery is not easy to grasp and be prone to slippage from hands, and simultaneously, handling safety relatively is suitable for existing neurosurgery.
Description of drawings
Below with reference to accompanying drawings the specific embodiments of this utility model is explained in more detail, wherein:
Fig. 1 is the structure drawing of device of this utility model;
Wherein, 1-cambered blade, 2-handle, 3-connector, 4-curved edge, 5-toothed cutting edge.
The specific embodiment
Scalpel is not easy to grasp and be prone to the problem of slippage from hands when in order to solve neurosurgery being undergone surgery, and this utility model provides a kind of novel neurosurgery Micro operating knife.Next specify this novel neurosurgery Micro operating knife.
Fig. 1 illustrates the structure drawing of device of this utility model.This novel neurosurgery Micro operating knife comprises cambered blade 1, the handle 2 that is provided with curved edge 4 and toothed cutting edge 5 and is connected cambered blade 1 and the connector 3 of handle 2; Wherein, Said handle 2 is the oval ring handle, and during use, the operator controls the oval ring handle; Can begin operation, this Micro operating knife landing and cause malpractice from hands accidentally in the time of can effectively preventing to perform the operation.
Above-mentioned curved edge 4 is arranged on the outer arc limit of cambered blade 1, and the arc core angle is 15 °～25 °.
Above-mentioned toothed cutting edge 5 is arranged on the inner arc limit of cambered blade 1.
The major radius of above-mentioned oval ring handle is 2: 1 with the ratio of short radius, conveniently takes.
Above-mentioned connector 3 is 1: 1～2: 1 with the ratio of oval ring handle major radius.
More than the specific descriptions of this utility model are intended to explain the implementation of specific embodiments can not be interpreted as it is restriction this utility model.Those of ordinary skills can make various variants on the basis of the embodiment that details under the instruction of this utility model, these variants all should be included within the design of this utility model.This utility model scope required for protection is only limited by described claims.
