Integrated therapy electrodes for endoscopic use

Abstract

The invention provides an integrated therapeutic electrode used under an endoscope, which comprises a basal body, and a water jet scalpel function unit, a high-frequency electric knife function unit and an argon knife function unit which are installed on the basal body; wherein, the water jet scalpel function unit comprises an electric water channel pipe made from conducting material, the front end of the electric water channel pipe is an outlet end, and the outlet end is a water jet scalpel nozzle; the high-frequency electric knife function unit comprises a high-frequency electric knife electrode; the argon knife function unit comprises an argon output pipe and an argon knife electrode, the front end of the argon output pipe is an outlet end, the outlet end is an argon knife nozzle, and the argon output pipe is provided with an inlet communicated with an argon source; the electric water channel pipe constitutes the high-frequency electric knife electrode and the argon knife electrode; the argon output pipe is sleeved outside the electric water channel pipe and is in clearance fit therewith, and the electric water channel pipe, relative to the argon output pipe, can move along the axial direction of the argon output pipe. The integrated therapeutic electrode used under the endoscope is integrated with the functions of a water jet scalpel, a high-frequency electric knife and an argon knife, can shorten the time for switching over different function units in the operation process, and has a simple structure.

Description

technical field [0001] The invention relates to a surgical instrument, in particular to an integrated treatment electrode used under an endoscope. Background technique [0002] The integrated therapeutic electrode used under the endoscope is a surgical accessory commonly used in conjunction with the endoscope. It usually needs to have the functions of electrocoagulation, electrocution and stripping, so as to minimize bleeding and quickly stop bleeding during the operation. [0003] The commonly used surgical accessories are: [0004] 1) High-frequency electric knife: it can quickly cut and stop bleeding, but it has the disadvantages of large thermal damage, indistinguishable edges due to tissue coagulation and carbonization, and prolonged healing time; [0005] 2) Argon Knife: The hemostasis of the cutting surface is rapid, and the thermal damage is shallower than that of the electric knife, but it has the disadvantages of being unable to stop the bleeding of large blood ve...

AI Technical Summary

Problems solved by technology

[0004] 1) High-frequency electric knife: it can quickly cut and stop bleeding, but it has the disadvantages of large thermal damage, indistinguishable edges due to tissue coagulation and carbonization, and prolonged healing time;

[0005] 2) Argon Knife: The hemostasis of the cutting surface is rapid, and the thermal damage is shallower than that of the electric knife, but it has the disadvantages of being unable to stop the bleeding of large blood vessels, and the coagulation surface is easily burnt and the boundary is unclear;

[0006] 3) Waterjet: There is no thermal damage to the wound surface, the separation is fast and the bleeding is less, and most of the small blood vessels can be preserved, but there is a disadvantage that bleeding cannot be stopped

[0007] It is difficult to achieve good results by using one of the surgical accessories alone, and usually requires multiple surgical accessories to be used together. However, frequent replacement of surgical accessories is not only inconvenient, but also prolongs the operation time and reduces the safety of the operation
