Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, and more specifically to an ophthalmic suture surgical forceps. Background Art

[0002] In today's medicine, the role of surgery cannot be ignored and is an important part of medicine. The more important surgical instruments used during the operation include scalpels and surgical forceps, especially in ophthalmic suture surgery.

[0003] The current ophthalmic suture surgical forceps, such as the "A Type of Ophthalmic Suture Surgical Forceps" proposed in the application number 202223539873.9, include a clamping end and a clamping mechanism, the outer side of the clamping end is provided with an anti-slip coating, the left side of the clamping end is connected to the clamping mechanism, and the right side of the clamping end is connected to a connecting component. The beneficial effect of the utility model is: a type of ophthalmic suture surgical forceps, by setting a clamping mechanism, when it is needed to be used, the finger presses the finger pinching plate, and the anti-slip pad on the outside of the finger pinching plate can increase the friction between the medical gloves and the surgical forceps to prevent hand slippage during use, then insert the bending plate into the groove of the connecting plate for fixing, then turn on the fill light, the fill light will provide power from the battery, the fill light can provide an additional light source during surgery, reduce the situation of local light shortage caused by obstacles, then use the resistance-increasing pad in the forceps petal to perform surgery, the resistance-increasing pad can increase friction and reduce slippage caused by blood when taking objects with the forceps.

[0004] The existing ophthalmic suture surgical forceps hold the two ends of the forceps so that the forceps flaps clamp the suture. Although this can pull and pull out the suture, in actual use, the operator cannot always maintain the same force during the process of clamping and pulling out the suture. When pulling out, a certain amount of force is easily unloaded due to slight shaking of the human hand, which affects the tightening degree or pulling out effect of the suture, making it inconvenient to use. Therefore, there is an urgent need to improve the technology of the structure of the ophthalmic suture surgical forceps to improve this equipment. Utility Model Content
