Description

Integrated sclera cingulum

Technical Field

The utility model relates to a material used in surgical operation. And more particularly to a surgical material used in an ophthalmic retinal detachment reduction surgery.

Background

Retinal detachment is a common eye disease causing blindness in ophthalmology, and if the treatment is not timely, the risk of blindness is caused, eyeball atrophy can be caused, and the appearance of the eyeball is influenced. The scleral buckle procedure removes vitreous traction by pressing against the sclera to circumferentially constrict the circumference of the eye, making the detached retina more easily repositionable, one of the most basic most commonly used procedures for treating retinal detachments. At present, the operation must use a silica gel material strip elastic band. When in use, the elastic band is prevented from sliding by the fixing ring. However, the tension of the scleral buckle and the pressure of the scleral buckle on the wall of the eyeball cannot be accurately determined during the operation. When the pressure is small, the vitreous traction can not be loosened, and when the pressure is large, the intraocular pressure is easy to rise, or the ischemia of the eye is easy to cause. Therefore, a novel scleral buckle band which is convenient to use, can directly measure the circumference of the eyeball and accurately judge the tension and the pressure of the scleral buckle band is needed clinically, so that the surgical complications are reduced, the surgical time is shortened, and the surgical success rate is improved.

Detailed Description

The present disclosure relates to a material for use in surgery. In particular, the present disclosure relates to a surgical material for use in an ophthalmic retinal detachment reduction procedure.

Fig. 1 and 2 illustrate an exemplary scleral buckle 001. The scleral buckle 001 includes a length measuring strip 002, an elastic band 003, and a securing ring 004. The length measurement strip rear end 005 and the elastic band rear end 006 are both connected to the fixing ring 004. The length measuring strip 002 is made of a low elastic flexible material, and the cross section of the length measuring strip is circular, or elliptical, square or other shapes. The surface of the front segment of the length measuring bar 002 has a striped length measuring bar scale 007. The elastic band 003 is made of a high-elasticity flexible material, is integrally in a strip shape, has a rectangular cross section, can also be in a trapezoid shape, an oval shape, an application shape or other suitable shapes, and has striped elastic band scales 008 on the surface of the front part. The elastic band 003 has a plurality of restricting rings 009 attached to its side. The length measuring bar 002 passes through the restriction ring 009. The side of the front part of the elastic band 003 is provided with an elastic band coupling structure 010 consisting of a plurality of convex structures. The width of the front end 011 of the elastic band is gradually reduced forwards. The elastic band rear end 006 is attached to a securing ring 004.

Fig. 3 shows a horizontal cross-sectional view of an example retaining ring 004. The inner surface of the fixing ring 004 is provided with a fixing ring coupling structure 012 which is composed of a plurality of concave structures and can be matched with the elastic band coupling structure 010 protruding from the side surface of the front part of the elastic band 003 to limit the front and back sliding of the elastic band 003.

FIG. 4 illustrates the use of an exemplary scleral buckle 001. In use, the scleral buckle 001 is first placed around the eyeball 014 and the initial circumference of the eyeball is determined by observing the corresponding reading on the length measurement bar scale 007 corresponding to the posterior edge 013 of the fixation ring. Then, the front end 011 of the elastic band penetrates through the fixing ring 004, the fixing ring 004 is kept still, the front end 011 of the elastic band is pulled forwards, the elastic band 003 is gradually tightened, and the actual circumference of the eyeball after the cerclage is judged by observing the corresponding reading on the scale 007 of the length measuring strip corresponding to the rear edge 013 of the fixing ring. At the same time, the corresponding reading on the corresponding band scale 008 of the retainer ring trailing edge 013 is observed. By analyzing the initial circumference of the eye, the actual circumference after the eye is cerclaged, and the readings on the band scale 008, the tension of the band 003 and its pressure against the eye wall can be derived. Depending on the actual need, the operator can pull the elastic band 003 forward or backward until the desired tension of the elastic band 003 and its pressure against the eye wall are reached. The excess parts of the length measuring strip 002 and the front section of the elastic band 003 are cut off. The other using method is as follows: first, the scleral buckle 001 is placed around the eyeball, and the initial circumference of the eyeball is determined by observing the corresponding reading on the length measurement bar scale 007 corresponding to the securing ring trailing edge 013. The corresponding reading of the band scale 008 corresponding to the desired eye circumference and the desired tension in the band 003 is then determined by computer program calculation or look-up using a look-up table. Next, the front end 011 of the elastic band penetrates through the fixing ring 004, the fixing ring 004 is kept stationary, the front end 011 of the elastic band is pulled forwards until the expected scale is reached, and redundant parts of the front section of the elastic band 003 and the length measuring strip 002 can be cut off according to actual needs.
