Bipolar electrocoagulator with suction function

Abstract

The invention relates to a bipolar electrocoagulator with a suction function. The bipolar electrocoagulator comprises a first finger portion and a second finger portion, wherein an end of the first finger portion is rotationally connected with a cylindrical rotating block; an end of the rotating block is connected with a joint rod; an end of the joint rod is connected with a long-strip-shaped sleeve rod; an end of the first finger portion is also provided with a high-frequency connecting head connected with an external electrocoagulator host; the lower portion of the joint rod is provided witha lower connecting opening; the lower connecting opening is connected with an upper end opening of a flow rate regulating valve through a connecting pipe; a lower end opening of the flow rate regulating valve is connected with an external connecting pipe; the external connecting pipe is connected with an external negative pressure mechanism; a regulating opening of the flow rate regulating valveis positioned on the outer side of the first finger portion; an end of the sleeve rod is provided with an electrode head; a through hole is formed in the electrode head; and the electrode head is connected to the interior of the flow rate regulating valve through a flexible pipe. The bipolar electrocoagulator has the advantage that the suction function of liquid and gas at an end of the electrodehead can be realized.

Description

technical field [0001] The invention relates to an electrocoagulator, in particular to a bipolar electrocoagulator with a suction function. Background technique [0002] Laparoscopy is a relatively new, minimally invasive technique for the diagnosis and treatment of intra-abdominal diseases. It is a fiber light source endoscope used for the inspection and treatment of abdominal organs and tissues, including laparoscopy, energy systems, light source systems, and pneumoperitoneum systems. and imaging system; it uses the front part of the mirror body to enter the abdominal cavity, which has a magnifying effect on the observed parts, and performs surgical operations through laparoscopic operating instruments. Surgical route of choice for treatment. [0003] In laparoscopic surgery, the electrocoagulator is a very frequently used operating device. The electrocoagulator mainly heats the tissue when the high-frequency and high-voltage current generated by the effective electrode t...

Problems solved by technology

[0003] In laparoscopic surgery, the electrocoagulator is a very frequently used operating device. The electrocoagulator mainly 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. , so as to achieve the purpose of cutting and hemostasis, but a large amount of smoke will be generated during the use of the electrocoagulator, and the smoke is difficult to discharge in the abdominal cavity in a short time, thus affecting the surgical field of view. It is necessary to use an aspirator to smoke to keep the surgical field of view clear. However, it is difficult to control the flow rate of the aspirator in the process of using the aspirator, which will affect the pneumoperitoneum effect while inhaling the smoke in the body, thus affecting the surgical operation

In addition, when the tissue has obvious bleeding, it will affect the working efficiency of the coagulator. Therefore, it is necessary to immediately coagulate the bleeding point when the blood on the surface of the tissue is sucked and the new blood has not yet flowed out, so as to improve the hemostatic effect. These operations are relatively cumbersome and costly. time, thus affecting the progress and efficiency of the operation
