The technical scheme of the invention is as follows:

a stopper for eyeball operation, which comprises a support frame and a fixer, and is characterized in that: the eyelid opening hooks are symmetrically arranged on the outer side of the bottom of the support frame, the fixed clamping grooves are symmetrically arranged on the inner side of the support frame, pins are arranged on the fixed clamping grooves, the fixing wings corresponding to the fixed clamping grooves are arranged on the fixing device, the fixing holes are formed in the fixing wings, the fixing device is movably mounted on the support frame through the matching of the fixing wings and the fixed clamping grooves, and the fixing device and the support frame are connected and fixed through the matching of the pins and the fixed holes; the support frame be the U type body, the handle is installed to one end screw thread of support frame.

The fixer is an annular body and consists of a fixing ring, a connecting ring and an assembling ring; the bottom of the connecting ring is fixedly provided with a fixing ring, and the top of the connecting ring is fixedly provided with an assembling ring; the two sides of the assembling ring are symmetrically provided with fixed wings, the upper surface of the assembling ring is provided with an assembling inner groove, an inner protective cover is movably arranged in the assembling inner groove, and an assembling outer groove is arranged outside the assembling inner groove; an outer protective cover is movably arranged in the assembly outer groove.

The inner protective cover and the outer protective cover are respectively semi-arc-shaped; the inner protective cover and the outer protective cover are respectively made of transparent materials.

One end of the assembling ring is provided with a handle mounting seat, and a thread mounting hole is formed in the handle mounting seat.

The fixing ring is made of medical silica gel material.

The invention has the advantages that:

the brake for eyeball surgery is simple and novel in structure and convenient to use, and can be conveniently held by the handle in the using process, so that the eyeball is fixed by the fixing ring; and the inner protective cover and the outer protective cover arranged on the assembling ring can cover and protect the eyeball so as to facilitate accidents in the operation process. The problem of current fixer suitability low, and because the design is unreasonable, when carrying out ophthalmic surgery for patient, medical personnel are difficult to grip, perhaps are difficult for the application of force, have increased the very big work degree of difficulty for medical personnel is solved. Meanwhile, the brake has the characteristics of good stability and high reliability, and is particularly suitable for fixing eyeballs in an ophthalmic operation.

Detailed Description

This a stopper for eyeball operation includes support frame 1 and fixer 7, and 1 bottom outside symmetry of support frame describes and is provided with the eyelid and

colludes

2, and 1 inboard symmetry of support frame is provided with fixing slot 3 for the assembly of fixer 7. The fixer 7 is an annular body, and the fixer 7 consists of a fixed ring 4, a connecting ring 5 and an assembling ring 6; the bottom of the connecting ring 5 is fixedly provided with a fixing ring 4 made of medical silica gel material, and the top of the connecting ring 5 is fixedly provided with an assembling ring 6; the two sides of the assembling ring 6 are symmetrically provided with fixed wings 8, and the fixed wings 8 are provided with fixed holes 9. One end of the assembling ring 6 is provided with a handle mounting seat 10, and the handle mounting seat 10 is provided with a thread mounting hole.

An inner assembling groove 11 is formed in the upper surface of the assembling ring 6, an inner protective cover 12 is movably mounted in the inner assembling groove 11, and an outer assembling groove 13 is formed in the outer side of the inner assembling groove 11; an outer protective cover 14 is movably arranged in the assembly outer groove 13. The inner shield 12 and the outer shield 14 are respectively semi-arc-shaped; the inner shield 12 and the outer shield 14 are each made of a transparent material.

A pin 15 is arranged on the fixed clamping groove 3 of the brake, the fixer 7 is movably mounted on the support frame 1 through the matching of the fixed wings 8 and the fixed clamping groove 3, and the fixer 7 and the support frame 1 are fixedly connected through the matching of the pin 15 and the fixed hole 9. The support frame 1 of the brake in the eyeball surgery is a U-shaped body, and a handle 16 is installed at one end of the support frame 1 in a threaded mode. It is conveniently held by the handle 16 during use to facilitate the application of force by medical personnel. In the use process, firstly, the eyelid of a patient is opened through the eyelid opening hook 2, and then the purpose of fixing the eyeball is realized through the fixing ring 4.

The inner protection cover 12 and the outer protection cover 14 of the brake can respectively rotate in the inner assembly groove 11 and the outer assembly groove 13, and the inner protection cover 12 and the outer protection cover 14 can be overlapped with each other; the inner protective cover 12 and the outer protective cover 14 are matched with each other to form a hemispherical protective cover to completely cover eyeballs of a patient; the inner protective cover 12 and the outer protective cover 14 can be matched with each other to enable the surgical site of the eyeball of the patient to leak out and cover other parts, and the purpose of preventing the other parts of the eyeball from being hurt by accidents in the surgical process is achieved. Since the inner shield 12 and the outer shield 14 are rotatable in the inner fitting groove 11 and the outer fitting groove 13, respectively, the lesion site of the eyeball does not have a specific position limitation on the shields, and thus, the utility model has an advantage of high applicability.

As an improvement, the brake can also be used independently, when in use, the fixer 7 is taken down from the support frame 1, and then the handle 16 is arranged on the assembling ring 6 through a threaded mounting hole. The brake is simple and novel, is convenient to use, and solves the problems that the existing fixator is low in applicability, and medical workers are difficult to hold or apply force when performing ophthalmic surgery on patients because the design is unreasonable, so that the great work difficulty is increased for the medical workers. Meanwhile, the brake has the characteristics of good stability and high reliability, and is particularly suitable for fixing eyeballs in an ophthalmic operation.
