Problems solved by technology

Because the tip of the optical fiber in the eye is blunt and round, the proliferating cord cannot be fixed while supporting it, and it often slips off repeatedly. Therefore, this operation is inefficient and easy to damage the retina.

Embodiment 1

[0028] The structural representation of the subretinal proliferating cord supporter of the present invention is as follows: figure 1 as shown, figure 2 for figure 1 Partial enlarged view of the front part of the rod body and the working part shown, image 3 A top view of the subretinal proliferating cord supporter of the present invention, Figure 4 for image 3 The partial enlarged view of the front part of the rod body and the working part is shown, wherein, 1 - the working part, 2 - the rod body, 21 - the main part of the rod body, 22 - the front part of the rod body, 3 - the handle, 31 - the handle body, and 32 - the connecting part. The subretinal proliferating cable supporter of the present invention includes a handle 3 and a rod body 2 fixedly connected to the handle 3. A working part 1 is arranged at the front end of the rod body 2. The rod body 2 is composed of a rod body main part 21 and a rod body front part 22. The body front portion 22 forms an obtuse angle ...

Embodiment 2

[0031] In order to obtain a better use effect, on the basis of Example 1, further, the subretinal proliferation cord supporter of the present invention is integrally formed of titanium alloy material, and the handle 3 and rod body 2 of the supporter are circular metal rods . Handle 3 can be made of handle body 31 and connecting portion 32, and connecting portion 32 is the conical rod that handle body 31 continues, and handle body 31 is long 80mm, and diameter is 4mm, and connecting portion 32 is long 20mm, and diameter gradually reduces from 4mm to 0.9 mm; the length of the rod body 21 is 35 mm, and the diameter from the end of the handle 3 to the rod body front part 22 gradually becomes thinner from 0.9 mm to 0.4 mm. Diameter is 0.4mm, forms 160 ° angle with rod body body 21, ( figure 2 The θ angle in is 160° angle); the working part 1 is an arc piece formed by bending a circular metal wire with a diameter of 0.4mm, the height of the arc piece is 0.5mm, and the opening width...

Abstract

The invention provides a subretinal proliferation cord supporting device which comprises a handle (3) and a rod body (2) fixedly connected with the handle (3), wherein a working part (1) is arranged at the front end of the rod body (2); the rod body (2) consists of a main rod body part (21) and a front rod body part (22); the front rod body part (22) and the main rod body part (21) form an obtuse angle; the working part (1) is a cambered piece arched to the rod body direction; the middle part of the cambered piece is fixedly connected with the front part of the front rod body part; the cambered piece and the front rod body part (22) are positioned on the same plane; furthermore, distances from two ends of the cambered piece to the tail end of the handle (3) are equal. The subretinal proliferation cord supporting device can stably support a subretinal proliferation cord, cannot fall off and is easy to operate; the operational efficiency is improved, and injury, which is caused by the operation, to retinas is reduced.

Description

technical field [0001] The invention belongs to the field of medical instruments, in particular to ophthalmic surgery medical instruments, more specifically a supporter for subretinal proliferation cords. Background technique [0002] Subretinal proliferative cords occur in proliferative vitreoretinopathy (PVR) after rhegmatogenous retinal detachment. Fibroblasts are formed, and retinal glial cells are also involved in its formation. In the study of 72 patients with PVR by Lewis et al., it was found that subretinal proliferative cords existed in 47% of patients, which partially hindered the reattachment of the retina and required surgical removal. The principle of surgical treatment of subretinal hyperplasia is: remove the subretinal hyperplasia as much as possible, if it is difficult, release the loose retinal reattachment. The operation technique of subretinal hyperplastic tissue is the most difficult and requires the highest precision in the whole operation of vitreoret...
