Abstract
A pair of extraocular muscle insertion locking forceps comprises a forceps handle and a forceps body. The forceps body comprises an upper piece and a lower piece which parallelly extend; the rear ends of the upper piece and the lower piece are elastically fixed on the forceps handle, curved cambered surfaces are formed the front end parts of the upper piece and the lower piece, and the curve direction of the cambered surfaces and the holding direction of the extraocular muscle insertion locking forceps are parallel to each other; and an upper forceps head and a lower forceps head are connected to the top ends of the cambered surfaces of the upper piece and the lower pieces respectively, and are meshed in a matched manner. The extraocular muscle insertion locking forceps can hold the level extraocular muscle insertion firmly, the surgery safety is good, and the remained scar after the surgery is small; and when the extraocular muscle insertion is firmly held, the eyeball is drawn owning to the gravity of the forceps, so that surgery area can be better exposed and the auxiliary hand of a doctor can be set free relatively, therefore the surgery is safer, and the operation is simpler and more flexible to complete complicated surgery operations.
Description
Technical field
This utility model relates to the operating theater instruments equipment technical field, relates in particular to a kind of extraocular muscles not-go-end snap close tweezer.
Background technology
In operation on extraocular muscle, extraocular muscles collar suture fixed and from having no progeny, the ophthalmologist adopts auxiliary hand-held full depth tooth tweezer to grip remaining apodeum, when exposing the art open country, the hand-held needle holder of the patient main force will be fixed in the shallow-layer sclera from the muscle of having no progeny.We can say that it is a step of risk maximum that this step operates in the stravismus operation on extraocular muscle.
Little for guarantee operation back cicatrix as far as possible, extraocular muscles is close to scleral surface more when disconnected, only keep less extraocular muscles not-go-end, when using common toothed forceps, the nondominant hand of tractive eyeball will remain firmly clamp position, if slightly slippage will appear in absent-mindedness, cause eyeball to rotate suddenly, the suture needle shallow-layer sclera of just being expert at of main force's hands is fixed as this moment, suture needle might take place penetrate sclera, detachment of retina, even visual loss.This operational error often has generation, especially often occurs among some abecedarians.
For fear of the unexpected slippage of extraocular muscles not-go-end, some patient adopts the method for curved hemostat clamp fixation muscles not-go-end, replaces common toothed forceps.Though the snap close of mosquito forceps can be liberated nondominant hand, eliminated the slippage that may cause because of the clamping absent-mindedness, the mosquito forceps head is too thick, and only be the bar shaped groove, gmatjpdumamics is poor, the bigger apodeum of only withing a hook at the end, firmly clamping, but this certainly will cause postoperative scar excessive, influences outward appearance.The clamp direction of mosquito forceps and direction of draw are vertical in addition, mosquito forceps need be revolved to turn 90 degrees just to carry out tractive, may cause the rotation of eyeball, directly influence surgical effect.
The utility model content
The purpose of this utility model is to design a kind of novel extraocular muscles not-go-end snap close tweezer, overcomes above-mentioned shortcoming of the prior art, addresses the above problem.
To achieve these goals, the technical solution adopted in the utility model is as follows:
A kind of extraocular muscles not-go-end snap close tweezer, comprise tweezer handle and tweezer body, described tweezer body comprise extend in parallel each other last slice and following sheet, described last slice and the rear end flexible fastening of described down sheet on described tweezer handle, described last slice and the fore-end of described down sheet be the cambered surface of bending, the bending direction of described cambered surface is parallel with the clamp direction of described extraocular muscles not-go-end snap close tweezer, described last slice cambered surface top is connected with the tweezer head, the cambered surface top of described down sheet is connected with down the tweezer head, describedly goes up the tweezer head and describedly descends the engagement that cooperatively interacts of tweezer head.
Described tweezer is provided with snap close on one's body, described snap close comprises and is fixed on the elastic force button locking plate on the described down sheet and is opened in lockhole on described last slice correspondence position, the front end of described elastic force button locking plate can pass described lockhole, and the front end of described elastic force button locking plate is provided with the reverse anti-slip groove that can tighten on the described lockhole.
The radius of curvature of described cambered surface is 14～25cm.
The radius of curvature of described cambered surface is 20cm.
The described tweezer head of going up is a bidentate tweezer head, and described tweezer head down is a monodentate tweezer head, the engagement that cooperatively interacts of gap between two teeth of described bidentate tweezer head and described monodentate tweezer head.
When the crown of described upward tweezer head and the described crown length of tweezer head down can make described upward tweezer head and the described engagement of tweezer head down, the crown of described upward tweezer head and the described crown of tweezer head down all protruded in the described field of conjugate action.
Described crown and the described length of the crown of tweezer head down that goes up the tweezer head is 0.5～1.0mm.
Described crown and the described length of the crown of tweezer head down that goes up the tweezer head is 0.9mm.
This utility model is the operating theater instruments in the ophthalmology operation on extraocular muscle, is used for extraocular muscles and fixes from the tractive of the remaining apodeum of having no progeny.
Be the artificial eyeball rotation of avoiding operating theater instruments in traction process, to cause, this utility model has designed parallel arc tweezer body, adopt the crooked cambered surface particular design parallel with the clamp direction, big arc tweezer is as last slice, little arc tweezer is as following sheet, and the direction of tractive is consistent in the direction that makes clamp and the art, can not cause eyeball to rotate during tractive, make operation technique more accurate, effectively.
For guaranteeing the stability of clamp, avoid slippage, this utility model has designed locker, and this tooth tweezer is at tweezer and has added locker, last slice lockhole is set, following sheet is provided with elastic force button locking plate, a left side, the right hand all can be operated, and have a clear superiority in than the snap close of mosquito forceps, easy to operate, promoted the safety of operation greatly.
In order to strengthen the gmatjpdumamics of tooth tweezer to sclera, this utility model has extended the crown of 0.3mm toothed forceps head to 0.9mm, crown slightly protrudes in occlusal surface when making the tweezer head closed, last slice be bidentate, following sheet is a monodentate, and the outstanding part in closed back can embed the shallow-layer sclera around the apodeum, to guarantee to firmly fix intimate slick apodeum, promptly guarantee the safety of operation, can reduce postoperative scar again.
The beneficial effects of the utility model are as follows:
1, this utility model can be lived smooth extraocular muscles not-go-end by firm clamp, and operation safety is good, and postoperative scar is little.
2, in the time of the firm clamp extraocular muscles of this utility model not-go-end, by the self gravitation direct motion tractive eyeball of tweezers, better expose the art open country, the nondominant hand that can liberate the patient relatively makes operation safer, operate simpler and easy flexibly, to finish more complicated operation technique.
