Abstract
The invention belongs to the field of medical equipment and mainly provides a sclera puncture knife. The sclera puncture knife comprises a knife handle, a knife head and a sheath, the sheath is in a shape of a column with one end open and detachably and fixedly sleeves the knife handle, and the sheath and the knife handle jointly cover the knife head. The sclera puncture knife has the advantages that owing to additional arrangement of the sheath, sanitation and safety of the knife head can be effectively protected; since the open end of the sheath is capable of closing automatically, sanitation performance of the sheath is guaranteed, and secondary contamination of the knife head is prevented; due to the fact that the knife head of the sclera puncture knife is in a detachably replaceable structure, sanitation protection of the knife head can be realized by the aid of the sheath in replacement of different knife heads.
Description
Technical field
The invention belongs to medical equipment field, more specifically, the present invention relates to a kind of sclerotic puncture cutter for intraocular surgery.
Background technology
At present, in the operations such as the cutting of wall of eyeball, the incision of corneoscleral junction or the excision of filter curtain, the surgical knife tool used in prior art is No. 11, No. 15 shavers, gem cutter, tunnel blade, paracentesis of anterior chamber cuttves etc.Very easily injure adjacent tissue during the operation of this type of scalpel, and the usage range of various cutter is narrow, Post operation easily causes unnecessary misery to patient; In addition, this scalpel is all generally expose completely in atmosphere, so just easily causes the sanitary condition of cutter to can not get corresponding guarantee.
For above-mentioned first problem, understanding is in the industry had to invent a kind of ophthalmology microknife, if application number is 01270965.4, the utility model patent that name is called " ophthalmology microknife ", in that patent, that central authorities are slightly thick, are about 0.5 ~ 1mm by circular for the head design of cutter, being thinned to blade, cutter head with knife neck handle towards edge is that a straight line is connected, described cutter head and described cutter neck compact siro spinning technology are also shaped successively and junction is smooth smoother, and described handle of a knife is that hair frustrates shape, not easily landing from hands.This scalpel is applicable to the operations such as the cutting of wall of eyeball, the incision of corneoscleral junction and/or the excision of filter curtain, thus solves the above-mentioned first problem mentioned.
Therefore, those skilled in the art need badly and provide a kind of and can provide the sclerotic puncture cutter of the cutter of safety, health for operation on sclera.
Summary of the invention
Main purpose of the present invention is to provide a kind of sclerotic puncture cutter, to solve above-mentioned the problems of the prior art mentioned.
For reaching above-mentioned purpose, technical way of the present invention is to provide a kind of sclerotic puncture cutter, described sclerotic puncture cutter comprises handle of a knife and cutter head, described sclerotic puncture cutter also comprises body, described body is the cylinder of an one end open, described body is detachable to be fixed by socket on described handle of a knife, and by coated for described cutter head together with described handle of a knife.
Preferably, the opening of described body can self-closed.
Further, described body is the body that silica gel is made.
As selection, described body and described handle of a knife are column type.
Further, described handle of a knife and described cutter head are detachable connection.
Particularly, the diameter of described cutter head is 0.9mm.
As selection, the diameter of described cutter head is 0.6mm.
Further, described handle of a knife is provided with anti-skid structure.
Therefore, adopt sclerotic puncture cutter of the present invention, some beneficial effect following can be reached:
One, sclerotic puncture cutter of the present invention, owing to adding body, therefore, it is possible to effectively protect the safe and sanitary of described cutter head;
Two, due in sclerotic puncture cutter of the present invention, the opening of described body can self-closed, this guarantees the sanitation performance of described body self, avoids making described cutter head generation secondary pollution;
Three, because the cutter head in sclerotic puncture cutter of the present invention is detachable changeable type structure, therefore when changing the different cutter head of use, hygienic protection can be carried out by described body to described cutter head.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Fig. 1 is the overall structure schematic diagram of the first embodiment of sclerotic puncture cutter of the present invention.
Fig. 2 is the structural representation of cutter head in the first embodiment of sclerotic puncture cutter of the present invention and handle of a knife.
Main purpose of the present invention is to provide a kind of sclerotic puncture cutter, composition graphs 1 and Fig. 2, in the first embodiment of the present invention, described sclerotic puncture cutter comprises handle of a knife 1 and cutter head 2, described sclerotic puncture cutter also comprises body 3, described body 3 is the cylinder of an one end open, and described body 3 is detachable to be fixed by socket on described handle of a knife 1, and by coated for described cutter head 2 together with described handle of a knife 1.
The present invention passes through the coated mode of described cutter head 2 with described body 3, for described cutter head 2 provides the use prerequisite of health, thus ensure that doctor is when using described sclerotic puncture cutter to perform the operation for sufferer, can not bring disadvantageous consequence because of the sanitary condition of scalpel to sufferer.
As a modification of the present invention, the opening of described body 3 can self-closed.
Being set to by the opening of described body 3 can the form of self-closed, can ensure that described body 3 can automatically be closed after socket handle of a knife 1, thus bring better protection of the environment for described cutter head 2.
