Smokeless high frequency electric knife

Abstract

The invention belongs to the technical field of surgical instruments and in particular relates to a smokeless high-frequency electric knife. The smokeless high-frequency electric knife comprises a handle (1), wherein an electrode (2) is arranged at the front end of the handle (1); a connecting wire (2) connected with an electric knife main engine is arranged on the handle (1); a bent part (21) is arranged at the front end of the electrode (2); a through hole (4) is formed in the bent part (21); a smoke absorbing path (5) is formed in the electrode (2); a gas guide tube (7) communicated with an absorbing device (6) is connected on the handle (1); one end of the smoke absorbing path (5) is positioned in the through hole (4) in the bent part (21); the other end of the smoke absorbing path (5) is communicated with the absorbing device (6) through the gas guide tube (7); a switch (8) is arranged on the absorbing device (6). The smokeless high-frequency electric knife can be used for timely absorbing gas generated by organism tissue gasification to provide a good operation field to a doctor, and can be used for reducing accidental injuries to a patient while facilitating the health of the doctor.

Description

technical field [0001] The invention belongs to the technical field of surgical instruments, in particular to a smokeless high-frequency electric knife. Background technique [0002] High-frequency electric knife is a common surgical instrument in surgery, such as figure 1 As shown, the high-frequency electric knife in the prior art includes a handle (1), the front end of the handle (1) is an electrode (2), and the handle (1) has a connecting line (3) for connecting with the main machine of the electric knife. The high-frequency electric knife heats the tissue when the high-frequency and high-voltage current generated by the effective electrode tip contacts the body, and realizes the separation and coagulation of the body tissue, thereby achieving the purpose of cutting and hemostasis. At present, the high-frequency electric knife has basically replaced the mechanical scalpel. It cuts extremely quickly, and has a good hemostasis effect, and can automatically disinfect the w...

AI Technical Summary

Problems solved by technology

However, the high-frequency electric knife is easy to gasify the body tissue during use, and produces a large amount of gas, which is easy for the operator to inhale, which is harmful to health

On the other hand, the generated gas makes the surgical field of view unclear, and the electrodes of the high-frequency electrosurgical knife are often blocked by the handle or the operator's hand, which affects the surgical operation, and even causes accidental injury and electric burns, etc.
