Description

Leep knife for gynecological minimally invasive treatment

Technical Field

The utility model belongs to the technical field of medical instruments, and particularly relates to a leep knife for gynecological minimally invasive treatment.

Background

The LEEP knife is a high-frequency electrotome, which generates ultra-high frequency (microwave) electric wave from the tip of an electrode, generates impedance from the tissue itself at the moment of contacting body tissue, absorbs the electric wave to generate high heat, and leads the water in cells to form Cheng Zhengqi wave to fulfill the aims of various operations such as cutting, hemostasis and the like. Doctor selects LEEP knife with different specifications according to the size or depth of focus of patient, and then makes electric shredding and rotary cutting focus tissue by rotating knife handle. During surgery, rotation may be achieved by motor drive. The size of focus tissues cut by the electric shredding at different angles is different, the larger the electric shredding angle is, the larger the tissue of a focus is cut, and the smaller the electric shredding angle is, the smaller the tissue of the focus is cut. During the treatment, the surface of pathological tissue is vaporized to generate smoke and odor, which not only affects the operation visual field, but also is easy to disperse the pungent odor in the operation room.

In the prior art, a plurality of motors for driving the electric shredding to rotate are positioned on a control console during operation, so that the distance between the motors and the electric shredding is too long, and when the motors drive the electric shredding, the cutter bar rotates to deviate, namely eccentrically rotates, so that the accuracy of the operation is not facilitated. The tissue size of the resected lesion may be determined by adjusting the angle of the electrical filament. The smoke removing treatment is carried out by adopting the negative pressure air suction mode of the external air pipe, but the smoking effect is not obvious because the external air pipe is far away from the treatment tool bit.

Disclosure of Invention

The utility model aims to provide a leep knife for gynecological minimally invasive treatment, which aims to solve the technical problems that an electric shredding eccentrically rotates and has an unobvious smoking effect due to the fact that a motor and an air suction pipe are far away from the electric shredding, and the size of a focus cut by the electric shredding is not easy to adjust.
