Abstract
一种新型的眼科硅油取出手术用防反流灌注头。它的主体结构为中空、环形的金属管，一端连接与巩膜穿刺口直径匹配的插头，共同组成灌注头。金属管内部为两片单向活动的半圆形阀门，阀门以金属管横断面最大横径为轴心，可旋转90度，闭合时与金属管横断面平行，开启时与金属管纵切面平行，阀门开启的方向为灌注管至眼球。手术中灌注头经巩膜穿刺口插入巩膜壁，如果眼内压低于玻璃体切割仪设定压力时，灌注液可经灌注管流入眼球内，如果眼内压高于设定压力，硅油也不会反流到灌注管中，以免造成灌注管液体粘滞力增大，阻碍灌注液进入眼球。
A new type of anti-reflux perfusion head for ophthalmic silicone oil removal surgery. Its main structure is a hollow, ring-shaped metal tube, one end of which is connected to a plug that matches the diameter of the scleral puncture port to form a perfusion head. Inside the metal tube are two semi-circular valves with one-way movement. The valve takes the largest transverse diameter of the metal tube as the axis and can rotate 90 degrees. , the direction of the valve opening is from the irrigation tube to the eyeball. During the operation, the perfusion head is inserted into the scleral wall through the puncture port of the sclera. If the intraocular pressure is lower than the set pressure of the vitrectomy instrument, the perfusion fluid can flow into the eyeball through the perfusion tube. If the intraocular pressure is higher than the set pressure, the silicone oil will not return. Flow into the perfusion tube, so as not to increase the viscosity of the perfusion tube liquid and prevent the perfusion fluid from entering the eyeball.
Description
Affiliated technical field
This utility model is a kind of new type medical equipment of application in the operation of ophthalmology silicone oil removal.
Background technology
Removal of silicone oil is the important component part of vitrectomy.So-called vitrectomy is exactly the method for under operating microscope, vitreous body, retinal diseases being treated by phaco.Along with the accumulation with experience of updating of operating theater instruments, operative indication constantly expands, and makes many ophthalmics that are considered in the past incurable disease obtain treatment.What vitrectomy adopted conventionally is triple channel closed type Vitrectomy, need to three sclerotic puncture mouths on wall of eyeball insert respectively pouring head (in order to constantly to infusion fluid in vitreous chamber, to maintain intraocular pressure, avoid atrophy of eyeball), optical fibers (throws light in order to ophthalmic, ophthalmic is operated in the clear visual visual field to carry out) and intraocular surgery apparatus (glass crop, intra-ocular scissors, intraocular forceps, film hook etc., in order to remove the forward and backward propagation film of muddy vitreous body and retina).Removal of silicone oil refers to after ophthalmic injects silicone oil and adheres to for retina again, after certain hour by the modus operandi of its taking-up.In this operation, the pouring head using is clinically except diameter difference at present, and 26S Proteasome Structure and Function is single, can not meet some special requirement, so making has the novel pouring head of personalized function, has important clinical meaning.
Summary of the invention
In order to solve the anti-perfusion pipeline that flow to of ophthalmic packing material in silicone oil removal operation, cause intraocular pressure control not good, this utility model provides a kind of novel antireflux pouring head.
This utility model solves the technical scheme that its technical problem adopts: agent structure is the metal tube of hollow, annular, and one end connects the plug mating with sclerotic puncture mouth diameter, jointly forms pouring head.Metal tube inside is the semicircle valve of two one-way movables, it is axle center that valve be take metal tube transverse section maximum transverse diameter, and rotatable 90 degree are parallel with metal tube transverse section when closed, parallel with metal tube longitudinal section during unlatching, the direction of valve opening is that intrusion pipe is to eyeball.When pouring head inserts after scleral walls, if intraocular pressure is during lower than vitrectomy instrument setting pressure, infusion liquid can be in intrusion pipe flows into eyeball, if intraocular pressure is higher than setting pressure, silicone oil can instead not flow in intrusion pipe yet, in order to avoid cause intrusion pipe liquid viscous force to increase, hinder infusion liquid and enter eyeball.
The beneficial effects of the utility model are, this silicone oil removal operation antireflux pouring head, can prevent in silicone oil removal operation that silicone oil is counter flow in intrusion pipe, make vitrectomy instrument accuracy controlling intraocular pressure more, contribute to the continual and steady of intraocular pressure, shorten operating time, reduce postoperative complication, clinical treatment is had to positive effect.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further illustrated.
Fig. 1 is outside drawing of the present utility model.This utility model comprises: annular body, internal valves and end plug.
Fig. 2 is the diagram under this utility model using state.Liquid can pass through through the one-way cock of pouring head.
The specific embodiment
This utility model agent structure is the metal tube of hollow, annular, and one end connects the plug mating with sclerotic puncture mouth diameter, jointly forms pouring head.Metal tube inside is the semicircle valve of two one-way movables, and it is axle center that valve be take metal tube transverse section maximum transverse diameter, rotatable 90 degree, and the direction of unlatching is that intrusion pipe is to eyeball.In operation, pouring head inserts scleral walls through sclerotic puncture mouth, if intraocular pressure during lower than vitrectomy instrument setting pressure, infusion liquid can be in intrusion pipe flows into eyeball, if intraocular pressure higher than setting pressure, silicone oil can instead not flow in intrusion pipe yet.
