Composite surgical knife head for micro-incision cataract phacoemulsification

Abstract

The micro-incision phacoemulsification combined surgical head for cataract belongs to medical equipment; the surgical head is composed of a triangular knife tip, a trapezoidal knife body and a trapezoidal knife tail in sequence, and its overall outer contour is in the shape of a symmetrical broken line; the height of the knife tip is The dimensions, the height of the knife body and the height of the knife tail are all 2 mm; the length of the bottom edge of the knife tip is 1.2 or 1.4 mm, the length of the bottom edge of the knife body is 1.4 or 1.5 mm, and the length of the bottom edge of the knife tail is 1.5 or 1.7 mm; The cutter head can accurately control the size of the internal and external incisions during the operation, and has the characteristics of simple structure, simple and convenient operation, easy to grasp, high operation quality and strong versatility.

Description

technical field [0001] The invention belongs to medical equipment, and mainly relates to a cataract surgical knife. Background technique [0002] Surgical treatment of cataract is currently the main method for radically curing cataract diseases. The surgical blades are all in a single triangular structure, and different sizes of blades are required for different surgical incisions. This not only makes it inconvenient for doctors to use and operate, but also increases medical costs and increases In addition, the surgical head with a single triangular structure has high requirements for the doctor's operation. The incision width of the same surgical head depends entirely on the surgeon's technical level and medical experience. When the knife is narrow, the knife is shallower, and the size of the incision is difficult to control accurately. If the incision is too small, the wound is easy to burn; if the incision is too large, the anterior chamber is unstable and there is water...
