Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and specifically to a medical LEEP knife facilitating the installation of a smoke suction tube. Background Art

[0002] A LEEP knife is a medical device used for minimally invasive diagnosis and treatment of cervical diseases. The LEEP knife adopts a directional radio frequency wave emission technology to generate a radio frequency wave field within the local tissue of the emitter. The radio frequency energy directly excites the liquid polar molecules within the tissue to generate plasma oscillations, causing the molecular bonds to break, and achieving a fine minimally invasive cutting effect at a low temperature (40°C - 70°C). The molecular wave oscillation frictional heat effect is used for hemostasis, tissue ablation, and contraction.

[0003] However, when the existing medical LEEP knife facilitating the installation of a smoke suction tube is in use, there are still certain problems: Existing adjustable LEEP knives and medical device components with a Chinese patent application number of 201811064903.0 relate to the technical field of surgical instruments. The adjustable LEEP knife includes a knife handle, a knife head, and an adjustment component; the adjustment component is connected within the knife handle, the adjustment component is connected to one end of the knife head, and the other end of the knife head is disposed outside the knife handle; the adjustment component can drive one end of the knife head to move, thereby adjusting the length of the other end of the knife head extending outside the knife handle. This solves the problem that the knife head of the LEEP knife has a fixed length and the doctor has to constantly change the surgical knife, making the doctor's surgery laborious. The adjustment component of the present invention is disposed within the knife handle, uses the adjustment component to fix one end of the knife head, and the adjustment component can drive one end of the knife head to move, thereby adjusting the length of the other end of the knife head extending outside the knife handle, eliminating the need to change the surgical knife and facilitating the doctor's surgery.

[0004] Through the design of the adjustment component, the adjustable LEEP knife solves the problem of the fixed length of the traditional LEEP knife head and the need for frequent replacement, providing convenience for the doctor's surgery. However, it lacks a mechanism for installing a smoke suction tube, resulting in the smoke generated during the surgery obscuring the doctor's line of sight and making the surgical field blurred. This may cause the doctor to have difficulty accurately judging the surgical site and depth, thereby increasing the surgical risk and the incidence of complications, and long-term exposure to the surgical smoke may have an adverse impact on the doctor's health.

[0005] In response to the above problems, an innovative design is carried out on the basis of the original medical LEEP knife facilitating the installation of a smoke suction tube. Summary of the Invention

[0006] The object of the present invention is to provide a medical LEEP knife that facilitates the installation of a smoke suction tube, so as to solve the problem raised in the above background technology. The existing adjustable LEEP knife solves the problem of the fixed length of the traditional LEEP knife head and the need for frequent replacement through the design of the adjustment component, which provides convenience for doctors during surgery. However, it lacks a mechanism for installing the smoke suction tube, resulting in the smoke generated during the operation blocking the doctor's line of sight and making the surgical field of view blurred. This may cause it difficult for doctors to accurately judge the surgical site and depth, thereby increasing the surgical risk and the incidence of complications, and long-term exposure to surgical smoke may have an adverse impact on the doctor's health.
