By adopting the protective device, operators can be effectively prevented from unnecessary injury during use process; the collision and friction between blades and between a blade and a knife holder as well as other hard materials can be avoided effectively; and the protective device for the surgical knife has the advantage that the service life of a cutting tool is prolonged.
Description
Technical field
This utility model relates to medical instruments field, relates in particular to a kind of scalpel, specifically is meant a kind of surgical knife preventer.
Background technology
The blade of all kinds of scalpels that use in the medical equipment as everyone knows, is very exquisite and sharp.In operation process; Multiple operating equipments such as scalpel, operating scissors, sewing needle, gripper clamp are placed in the apparatus dish; In the operation process, the nurse is when taking these apparatuses, and the blade that is exposed on the scalpel of outside unavoidably scratches finger; Perhaps the nurse also can scratch doctor's skin etc. in the process of passing doctor's scalpel, brings unexpected injury to medical personnel; When scalpel being carried out the cleanse and disinfect processing; Because the blade of scalpel is very sharp, brings certain danger to the operator, a little less than blade is highly brittle again simultaneously; If meet above the apparatus of other blade, handle of a knife or other hard; Blade can produce tipping or wearing and tearing, makes the passivation of scalpel blade, greatly reduces the service life of scalpel.
The utility model content
The technical problem that this utility model will solve is to the existing in prior technology weak point, and a kind of surgical knife preventer with better safeguard function is provided.
The technical solution of this utility model is, following a kind of surgical knife preventer is provided, and comprises sheath, and at least one mask of described sheath has opening, and the sheath sheet that constitutes sheath is provided with through hole.
Adopt such scheme, both can protect the operator in use, the scalpel blade is protected, sheath is provided with through hole, is convenient to the turnover of cleanout fluid and disinfectant solution.
As preferably, described sheath sheet comprises gentle matter internal layer and hard skin.Adopt such scheme, soft internal layer can effectively be protected blade, and one hand was taken off it when the hard skin can the handled easily person uses.
As preferably, described gentle matter internal layer is a layer of silica gel.Silica gel matter is soft, can effectively protect blade, meets medical device selection category simultaneously, nontoxic, health.
As preferably, described hard skin is a hard plastic layer.Why select hard plastic layer for use, the one, the convenient use, the 2nd, draw materials conveniently, make simple, with low cost.
As preferably, described gentle matter internal layer is provided with mastoid process.Adopt this programme, mastoid process has the effect of pure and fresh blade, increases friction simultaneously, prevents coming off voluntarily of sheath.
As preferably, the two sides of described sheath has opening, and the adjacent and opening in described two sides fuses.Adopt this programme, make things convenient for loading onto and taking off of sheath.
As preferably, the sheath sheet of described edge of opening is provided with anti-the dropout.Adopt this programme to prevent coming off voluntarily of sheath, and coming off unexpectedly in the time of cleaning.
As improvement, described mastoid process prevents threading off to constitute than other position length in the length at edge of opening place.Adopt this programme, the anti-dropout can specially be set, simple in structure, easily manufactured, loading onto and taking off of sheath is also comparatively simple.

The specific embodiment
For ease of explanation,, the surgical knife preventer of utility model is elaborated below in conjunction with accompanying drawing.
Shown in Fig. 1 to Fig. 4, a kind of surgical knife preventer comprises sheath 1; Described sheath 1 two sides has opening 1.2; Adjacent and the opening 1.2 in described two sides fuses, and the sheath sheet 1.1 that constitutes sheath 1 is provided with through hole 1.3, and described sheath sheet 1.1 comprises gentle matter internal layer 1.1.1 and hard skin 1.1.2; Described gentle matter internal layer 1.1.1 is a layer of silica gel; The outer 1.1.2 of described hard is a hard plastic layer, and described gentle matter internal layer 1.1.1 is provided with mastoid process 1.1.1.1, and described mastoid process 1.1.1.1 prevents dropout 1.1.3 than other position length to constitute in the length of opening 1.2 edges.
Work embodiment: the cutting edge side of scalpel is inserted the opening of this utility model, all fill in the sheath 1 up to the cutter head part, in the operation use; Because cutter head part places sheath 1 fully, take with transmittance process in, avoided the harm of blade to human body; After the doctor took in the hands, because sheath 1 skin is moulded a layer 1.1.2 for hard, internal layer was that soft layer of silica gel 1.1.1 processes; Available one hand is held handle of a knife; With thumb sheath 1 is chosen down gently, be positioned in the recovering tray, use more convenient; Before cleanse and disinfect is handled, earlier sheath 1.1 is installed in cutter head, carries out cleaning and sterilizing then and handle, because the sheath sheet 1.1 of sheath 1 is provided with through hole 1.3, cleanout fluid and disinfectant solution can pass in and out easily, and cutter head is cleaned up and thorough disinfection in this process.At the same time, this utility model has been avoided collision and the friction between blade and blade, handle of a knife and other hard materials, and the blade of scalpel is effectively protected, and the stage property life-span prolongs.
In the above-described embodiments; Preferred forms to this utility model is described, obviously, and under the inventive concept of this utility model; Still can make a lot of variations; Replaceable like the material of described hard plastic layer 1.1.2 is foil or other hard material, and replaceable like described layer of silica gel 1.1.1 material be perhaps other soft material of rubber, for another example the variation of the position of through hole 1.3, size and quantity etc.At this, should explain that any change of under the inventive concept of this utility model, being made all will fall in the protection domain of this utility model.
