High-frequency electric knife pen

Abstract

The invention discloses a high-frequency electric knife pen. The high-frequency electric knife pen comprises a knife handle, a knife head, a knife head pushing button, a knife head control switch and a connecting cable. The knife handle is of a hollow structure, the knife head is arranged at one end in a knife handle cavity, the other end of the knife head is connected with the connecting cable, the connecting able is led out of the other end of the knife handle and connected with a power plug; the knife head control switch is arranged on the outer wall of the knife handle; the knife head pushing button is arranged at the back end of the knife head, and a knife-head-pushing-button sliding groove is formed in the knife handle. According to the high-frequency electric knife pen, the knife head extends out of the knife handle to use when an operation is required, the knife head can be retracted in the knife handle in the non-operation state, and fault injuries and hidden danger when the knife head is exposed are avoided; a spare knife head can start to be used when an accident of a common knife head appears, and it is avoided that as the knife pen is temporarily replaced, the operation time is prolonged, and pains of patients are increased.

Description

technical field [0001] The invention relates to the technical field of medical electrosurgical instruments, in particular to a high-frequency electrosurgical knife pen. Background technique [0002] High-frequency electric knife is a device that blasts and solidifies tissue cells through high-frequency arc tunnels to achieve cutting and hemostasis effects based on the principle of high-frequency arc tunnels. Compared with traditional mechanical scalpels, it has faster cutting speed and better hemostasis effect. , suitable for a wide range of operations, simple operation, safe and convenient, and can meet the basic requirements of surgical operations such as cutting, hemostasis, and injury reduction. Clinically, the use of high-frequency electric knife can greatly shorten the operation time, reduce the amount of blood loss and blood transfusion of patients, reduce the incidence of complications, and save operation costs. Due to the reasonable hemostasis principle and excelle...

AI Technical Summary

Problems solved by technology

[0003] At present, during the operation of the high-frequency electrosurgical knife pen, there are situations such as insufficient preparation of the knife pen or scabbing of the knife pen. When an unexpected situation occurs, the knife pen of the high-frequency electric knife is not easy to replace, causing certain troubles to the doctor’s operation , which prolongs the operation time and increases the pain of the patient

Moreover, the current electrosurgical knife pens are generally exposed, without protective measures, are easily damaged, and have certain potential safety hazards
