Abstract

The utility model relates to a blade holder for the eye surgery, which belongs to the field of surgical instruments and techniques. The holder comprises a handle and an arm. The handle and arm are hinged together by a jointed shaft. The arm in front of the jointed shaft bends at an angle (R) of 15-45 degrees towards the vertical direction of the shaft axis. The utility model has the advantages of simple and reasonable structure and ease of use. The blade holder ensures the blade is of the same direction as the incision. The holder is suitable for the small incision congenital cataract surgery.

Description

A kind of ophthalmologic operation blade drive rotaining device

Technical field

This utility model belongs to the medical surgical instrument technical field, relates to a kind of ophthalmologic operation blade drive rotaining device.

Background technology

In cataract ultrasonic emulsification and the non-phacoemulsification cataract extraction operation of little otch, usually need to do little otch, present conventional pioneering operation is to adopt three cutter, finish the sclerocornea tunnel incision with tunnel blade, carry out paracentesis of anterior chamber with keratome again, using side to cut stab knife at last undergos surgery, these scalpels that adopt all are disposable import scalpels, cost an arm and a leg, access times are few; Utilize the operation method of cheap razor blade clinically in addition, this method is carried out incision surgery by clamper clamping blade, wherein clamper comprises handle, rotating shaft and clamping limb, its anterior clamping limb is straight shape, behind the clamping blade, the direction of blade and clamper is consistent, and the tunnel incision direction of little otch requires to be basically level, if but that patient's face splits is less, eye socket is darker, just can not fully blade be put into horizontal direction and operate, and then cause tunnel incision imperfect, not reach the requirement of little otch.

The utility model content

The purpose of this utility model provides a kind of ophthalmologic operation blade drive rotaining device that can realize little otch, simple operation.

This utility model is realized above-mentioned purpose by the following technical solutions: the ophthalmologic operation blade drive rotaining device, comprise handle, clamping limb, and handle and clamping limb are hinged by jointed shaft, and the clamping limb of jointed shaft front is to the axis normal direction bending of jointed shaft.

Bending angle R is 15～45 °.

The clamper front end retained part lateral bending that the utility model proposes, bending angle R is 15～45 °, when the clamping razor blade undergos surgery, razor blade just can be put into level, can accomplish in the good visual field that blade is consistent with cut-out direction, finish small incision cataract surgery, this utility model is simple and reasonable, and is easy and simple to handle.
