Abstract

The utility model discloses an eye surgery bistoury comprising a bistoury handle, a bistoury body and a bistoury head, wherein the bistoury body is arranged at the front end of the bistoury handle; the bistoury head is arranged at the front end of the bistoury body; the bistoury head has a semi-round flat structure; the arc-shaped edge of the bistoury head is a thin edge; one side of the linear edge of the bistoury head is fixed at the front end of the bistoury body; the plane of the bistoury head and the central axis of the bistoury body form an angle being 30 to 45 degrees; the thickness of the thickest part at the center of the bistoury head ranges from 0.1mm to 0.4mm; and the surface of the bistoury handle is provided with a strip-shaped nonskid pattern. In the eye surgery bistoury, the bistoury head is made into a semi-round structure with one thick rear end and a thin circumference; therefore, the stability of the bistoury head is reinforced, sharp parts are eliminated; eyes are not damaged easily; and the surgery has higher flexibility and safety; furthermore, the bistoury head is made into the structure which forms an angle being 30-45 degrees with the bistoury body so that a doctor can clear observe the surgery situation during the surgery; therefore, the eye surgery bistoury can be used more conveniently and has higher safety.

Description

A kind of ophthalmology scalpel

Technical field

This utility model relates to the medical equipment technical field, is specifically related to a kind of ophthalmology scalpel.

Background technology

The ophthalmic diseases meeting causes great influence to patient's life, therefore, usually need treat by performing the operation for more serious ophthalmic diseases, as dissecing to wall of eyeball, the incision of corneoscleral junction, filter curtain excision etc., at present, this type of operation is adopted No. 11 usually, pick the palpus cutter for No. 15, the gem cutter, tunnel blade, cutters such as paracentesis of anterior chamber cutter, above-mentioned cutter scarcely is the special-purpose cutter of ophthalmologic operation, and the straight bladed structure of cutter head is easy to operate the contiguous tissue of focus in operation process, there is very big potential safety hazard, the degree of accuracy of operation is lower, probably causes old complaint just to be cured, and has caused the accident of new disease again.

The utility model content

The technical problems to be solved in the utility model provides a kind of rational in infrastructure, safe, ophthalmology scalpel of being exclusively used in ophthalmologic operation.

For solving the problems of the technologies described above, this utility model adopts following technical scheme: a kind of ophthalmology scalpel, comprise handle of a knife, blade and cutter head, blade is installed in the handle of a knife front end, cutter head is installed in the blade front end, it is characterized in that: the flat structure of cutter head semicircular in shape, the radiused edges of cutter head is thin blade, linear edge one side of cutter head is fixed on the front end of blade; Become 30-45 ° of angle between the plane at cutter head place and the blade central shaft, that is to say that the relative blade of cutter head bends.

Preferably, the center of described cutter head the thickness at thick position be between the 0.1-0.4mm.

Preferably, described handle of a knife surface is provided with the anti-skidding stricture of vagina of strip.

Preferably, described handle of a knife, blade and cutter head adopt rustless steel to make.

This utility model has not only strengthened the steadiness of cutter head, and has eliminated sharp-pointed position by cutter head being made rear end semicircular structure thick, that approach on every side, is difficult for eyes are caused damage, making operation have higher motility and safety; In addition cutter head is made the structure that becomes 30-45 ° of angle with blade, this structure can make the doctor can clearly observe the situation of operation when performing an operation, and not only uses more conveniently, and safety is higher.
