[0018] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0019] See also Figure 1-3 The utility model provides a technical solution: a scleral cutting knife for trabeculectomy, comprising a knife handle 1, one end of the knife handle 1 is fixedly connected to a curved connecting rod 2, and the other end of the curved connecting rod 2 is fixedly connected to a cutting knife head 3.
[0020] A first engraved mark 4 is provided on the upper surface of the cutting head 3 , and the first engraved mark 4 is 3 mm away from the tip of the cutting head 3 on one side. A second engraved mark 5 is provided on the upper surface of the cutting head 3 .
[0021] The second mark 5 is located on the other side of the first mark 4 with a spacing of 1 mm. The surface of the handle 1 is provided with a plurality of anti-slip grooves 6. The first mark 4 is flush with the second mark 5 and the upper surface of the cutting head 3.
[0022] A first mark 4 and a second mark 5 are provided on the surface of the cutting blade 3, which can help the surgeon to control the depth and range of the cutting more accurately and reduce errors caused by improper operation. The presence of the scale provides a standardized reference for the surgery, so that different doctors can follow the same standards when performing scleral cutting, thereby improving the repeatability and consistency of the surgery.
[0023] With the help of the first mark 4 and the second mark 5, the doctor can determine the incision position and depth more quickly without frequent adjustments or repositioning during the operation, thereby shortening the operation time and improving the operation efficiency. For beginners or doctors in training, the scale marks on the sclera cutter can serve as an intuitive teaching tool to help them master surgical skills more quickly and improve the success rate of the operation.
[0024] The anti-slip grooves 6 facilitate improving the anti-slip performance of the staff during the surgical operation, thereby improving the stability during the operation.
[0025] Furthermore, a plurality of anti-skid patterns 6 are evenly distributed and spaced along the surface of the knife handle 1 . The anti-skid patterns 6 can effectively improve the anti-skid property of the knife handle 1 , thereby increasing the success rate during surgery.
[0026] Furthermore, a plurality of reinforcing ribs 8 are fixedly connected between the side wall of the curved connecting rod 2 and one end of the shank 1 , and the plurality of reinforcing ribs 8 are evenly spaced and distributed in a circular pattern along the surface of the curved connecting rod 2 .
[0027] In this embodiment, the reinforcing rib 8 improves the connection strength between the handle 1 and the curved connecting rod 2, thereby increasing the service life of the cutting knife.
