Abstract

The utility model relates to a blade holder in ophthalmologic operation, which belongs to medical treatment surgical instruments. The device comprises handle and retain arm, which are hinge connected together with hinge joint axle, the front retain arm part of the hinge joint axle bends toward the direction of axial ray, the bending angle R is 15 to 45 degrees. The utility model is simple in structure and convenient in operation, the direction of the blade is coincident with that of the incisal opening in the operation using the holder, and cataracta operation with tiny incisal opening can be completed.

Description

The 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 direction bending of jointed shaft.

Bending angle R is 15～45 °.

The clamper front end clamping limb 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.
