Double-pole electric coagulation aspirator

Abstract

The invention relates to a bipolar electric coagulation suction apparatus, which is mainly applicable to a nasal sinuses operation on a human body. On the basis of the prior art, the bipolar electric coagulation suction apparatus is also provided with a front electric coagulation head, a rear electric coagulation head, an external insulating tube, an internal insulating tube, a handle pressing cap, an electrode connecting sheet and an electrode connecting spring, wherein the front electric coagulation head is positioned on the front end parts of the internal insulating tube and an inner tube and is welded with the inner tube; the rear electric coagulation head is positioned on the front end parts of the external insulating tube and an outer tube and is welded with the outer tube; the end faces of the front electric coagulation head and the internal insulating tube extend out of the end face of the rear electric coagulation head, and the rear electric coagulation head and the outer tube are arranged between the external insulating tube and the internal insulating tube; and the handle pressing cap is connected with a handle, the electrode connecting sheet is fixed with the outer tube, and the electrode connecting spring is positioned between the electrode connecting sheet and an electrode plug. The bipolar electric coagulation suction apparatus has a reasonable design, not only can achieve electric coagulation and suction, but also can make two poles not contact the human body directly to avoid burning the human body; besides, the bipolar electric coagulation suction apparatus is safe, convenient and reliable to use.

Description

technical field [0001] The invention relates to a medical device, in particular to a bipolar electric coagulation suction device, which is mainly suitable for sinus surgery of human body. Background technique [0002] When performing human sinus surgery, the nasal bone needs to be separated from the periosteum, bleeding needs to be sucked out and the bleeding point needs to be electrocoagulated, so an electrocoagulation aspirator is required. In the prior art, Chinese patent application 200610050577, 9, an invention patent application named "sinus electrocoagulation suction device" is disclosed, which includes a handle with a hollow structure, and is equipped with suction joints, electrodes, thermoplastic tubes and suction tubes at the same time. The suction joint and the handle are connected by thread, the electrode and the handle are also connected by thread, the thermoplastic tube is glued to the handle, and the suction tube and the thermoplastic tube are fixed by socket,...

AI Technical Summary

Problems solved by technology

Although the electrocoagulation aspirator of this structure realizes both functions of electrocoagulation and attraction at the same time, it still has the following defects in use: its structural design is not reasonable enough, and it is a monopolar electrocoagulation aspirator, that is, in use, one of the One pole is connected to the electrode plug, while the other pole is connected to the human body. It is very easy to burn the human body when using it, and it is not safe and convenient to use.

And Chinese patent application 92108653, 9, the invention patent application titled "hollow coagulator for ENT department", it also has the defect that the structural design is not reasonable enough, and it is a monopolar electrocoagulation suction device, which is very easy to burn the human body during use. Not safe enough, convenient
