Abstract
The utility model discloses an eye pressurization ball bag and belongs to the field of medical devices. The eye pressurization ball bag can be used in a retinal detachment operation and an orbit operation. The eye pressurization ball bag is composed of a ball bag body and a needle core. The needle core is composed of a needle head and a needle tail, wherein the needle head and the needle tail are of hollow structures. The needle tail can be connected with an injector. Liquid or gases are injected into the ball bag body through the needle head so as to expand a head portion of the ball bag body. The ball bag body is made of silica gel, silicon rubber and latex so that the bag ball body is smooth in surface and soft. The ball bag body structurally comprises the head portion of the ball bag body, a body portion of the ball bag body and a tail portion of the ball bag body. When the injector is used for injecting the liquid or the gases through the needle core, the head portion of the ball bag body can be expanded to be in the shape of a ball or a horizontal rugby or a vertical rugby, and certain pressure is formed on peripheral tissues. The body portion of the ball bag body can not be expanded, and a scale mark line is arranged on the surface of one end, connected with the head portion of the ball bag body, of the body portion of the ball bag body. A self-closing valve is arranged in the tail portion of the ball bag body. When the needle core is inserted, the self-closing valve is opened; when the needle core is pulled out, the self-closing valve is closed; and therefore, the liquid and the gases in the ball bag body can not flow back.
Description
Technical field
This utility model apparatus belongs to medical instruments field, specifically is the eye pressurization sacculus that can be used for surgery of retinal detachment and eye socket operation.
Background technology
Surgery of retinal detachment and eye socket operation are the common operations of ophthalmology.The outer pressurizing block volume of surgery of retinal detachment use at present is big, and the wound surface of surgical exposure is big, needs sutured in sclera, the suture needle sutured might be worn out eyeball when sclera, operation risk is big, need expose wound surface again when taking out outer pressurizing block, dermal sutures out, complicated operation is hemorrhage easily.Eye socket operation eye socket inner space is narrow and small, includes multiple important nerve, blood vessel and muscular tissue, and structural change is various, and the operation technique complexity is hemorrhage easily, lacks corresponding exposure apparatus.
Summary of the invention
The objective of the invention is to design and manufacture eye pressurization sacculus simple in structure, easy to operate and safe.This utility model eye pressurization sacculus is made up of sacculus (1) and nook closing member (2).Nook closing member (2) is made up of syringe needle (4) and backshank (3); Syringe needle (4) and backshank (3) are hollow-core construction, and backshank (3) can connect syringe, inject liquid or gas with dilating sacculus head (7) by syringe needle (4) to sacculus (1).Sacculus (1) adopts silica gel, silicone rubber and latex to make smooth surface, soft sacculus, and structure is made up of sacculus head (7), sacculus body (6) and sacculus afterbody (5); When using syringe to inject liquid or gas by nook closing member (2), the inflatable expansion of sacculus head (7) forms spherical or horizontal rugby shape or perpendicular rugby shape, and surrounding tissue is formed certain pressure; Sacculus body (5) can not expanse, with sacculus head (7) end surfaces that joins the scale mark line is arranged; The sacculus afterbody is with self-closing valve in (5), self-closing valve opening when inserting nook closing member (2), and the liquids and gases in the self-closing valve closing when extracting nook closing member (2), sacculus can't backflow.
This eye pressurization sacculus is compared with the outer pressurizing block of known general-purpose and is had the following advantages:
1. simple to operate: as only to need to isolate a long and narrow passage with passivity such as iris repositors during the operation of eye pressurization sacculus, stretch into eye pressurization sacculus to preposition, syringe injects liquid or gas from nook closing member, dilating sacculus, and whether the position of observing sacculus reaches the requirement position; As do not reach, syringe is extracted liquid out or gas can reappose sacculus; As reaching the requirement position, withdraw from nook closing member, the liquids and gases in the sacculus can't flow out because of self-closing valve, and sacculus is fixed in original position; Take out sacculus as need, insert nook closing member again, extract the liquids and gases in the sacculus out, can extract sacculus;
2. use safety: eye pressurization sacculus adopts medical silica-gel, silicone rubber and latex to make good biocompatibility; Smooth surface, softness are placed when taking out little to the surrounding tissue damage; During expansion slowly, the passivity expansion, little to the surrounding tissue damage, be difficult for hemorrhagely, sacculus injects behind liquid or the gas fixing, need not sew up, and wears out the danger of eyeball when avoiding the suture needle sutured.

The specific embodiment
When this utility model eye pressurization sacculus was used for surgery of retinal detachment, according to checking ceasma position and the quantity of finding before the art, passivity such as use iris repositor were isolated the position that a long and narrow passage arrives the ceasma place.If have only a ceasma, select the sacculus of the expansible globulate of sacculus head for use; If a plurality of ceasmas of same quadrant are on the same warp, select the sacculus of the perpendicular rugby shape of the expansible one-tenth of sacculus head for use; If a plurality of ceasmas of same quadrant are on the same parallel, select the sacculus of the horizontal rugby shape of the expansible one-tenth of sacculus head for use.The eye sacculus that pressurizes is extend into preposition, and syringe injects liquid or gas from nook closing member, dilating sacculus, and whether the position of observing sacculus reaches the requirement position; As do not reach, syringe is extracted liquid out or gas can reappose sacculus; As reaching the requirement position, withdraw from nook closing member, the liquids and gases in the sacculus can't flow out because of self-closing valve, and sacculus is fixed in original position; Take out sacculus as need, insert nook closing member again, extract the liquids and gases in the sacculus out, can extract sacculus.
When this utility model eye pressurization sacculus is used for the eye socket operation, eye socket lacuna according to required expansion, passivity such as use iris repositor are isolated a long and narrow passage, the eye sacculus that pressurizes is extend into preposition, syringe injects liquid or gas from nook closing member, and dilating sacculus carries out passivity expansion slowly to the eye socket lacuna of required expansion, and carry out hemostasis by compression, expose the eye socket lacuna of required expansion; Take out sacculus as need, insert nook closing member again, extract the liquids and gases in the sacculus out, can extract sacculus.
