Embodiment Construction

[0014] The present invention is further described below in conjunction with embodiment and accompanying drawing.

[0015] Such as figure 1 , figure 2 As shown, the macular hole internal limiting membrane transplantation surgical instrument includes a handle 1 , an operating rod 2 and a bending piece 3 . The operating rod 2 is connected end to end with the handle 1 . The bending piece 3 is arranged at the end of the operating rod 2 and is arranged at an angle A with the operating rod 2 . The range of the included angle A can be set according to the convenience of actual use. Preferably, the angle A between the bending piece 3 and the operating rod 2 is a right angle, that is, the bending piece 3 is perpendicular to the operating rod 2 . The handle 1 is provided with an optical fiber 4, the optical fiber 4 passes through the middle of the handle 1, and one end of the optical fiber 4 is arranged to emit light toward the bending piece 3, and the other end is connected to a li...

Abstract

The invention discloses a macular hole inner limiting membrane transplanting surgical apparatus. The surgical apparatus comprises a handle, an operating rod and a bent sheet. The operating rod is connected with the handle in a head-tail connection mode; the bent sheet is arranged at the end of the operating rod, and an included angle is formed between the bent sheet and the operating rod. When the macular hole inner limiting membrane transplanting surgical apparatus is in use, a doctor can conveniently fill the macular hole with the inner limiting membrane. Even if the inner limiting membrane is larger than the hole, the bent pipe can protrude into the lower portion of macula lutea from the hole, fill the inner limiting membrane with the macula lutea, and level the inner limiting membrane. The handle is provided with a radiating light, thus the doctor is assisted in observation, and surgery is conveniently operated.

Description

technical field [0001] The invention relates to a surgical instrument for macular hole inner limiting membrane transplantation. Background technique [0002] When treating a macular hole, one of the treatment options is the use of ILM grafts, which include ILM coverage and tamponade. During the specific operation, a layer of inner limiting membrane is peeled off from the retina in the macular area, and it is covered and packed into the macular hole. But in practice, the ILM size is larger than the macular hole. There are currently no suitable devices available for grafting the internal limiting membrane into the macular hole. Contents of the invention [0003] One of the purposes of the present invention is to overcome the deficiencies in the prior art, and provide a macular hole internal limiting membrane transplantation surgical instrument that helps to pack and cover the internal limiting membrane into the macular hole. [0004] To achieve the above object, the prese...
