Problems solved by technology

The electric knife is generally used to cut some adhesions in the abdominal cavity, but smoke will be generated during use, which will blur the picture taken by the lens and interfere with the surgical field of view, making it difficult for doctors to observe the situation in the abdominal cavity

Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. Wherein the same components are denoted by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the words "bottom" and "top "Face", "inner" and "outer" refer to directions toward or away from, respectively, the geometric center of a particular component.

[0022] refer to Figure 1-6 As shown, a laparoscopic electric knife includes an electric knife handle 1 for holding. The electric knife handle 1 is connected with a penetrating rod 11 for inserting into the abdominal cavity. The electric knife head 12 and the electric knife handle 1 are also equipped with an air pump 34 for generating negative pressure. The air pump 34 is connected with a suction pipe 2 and a solenoid valve 3 for controlling the openi...

Abstract

The present invention discloses a laparoscopic knife. The key points of the technical solution include a sensor. The sensor is used to sensor whether there is smoke. The sensor is connected to the solenoid valve.In the abdominal cavity, the electric knife head cuts the smoke, and the sensor feels to the smoke, and then controls the solenoid valve to open the inhalation tube to absorb the smoke and discharge the body through the air pump.The present invention has the following useful effects: After the sensor is sensing to the smoke, the aspirational valve will be turned on by controlling the solenoid valve. The negative pressure generated by the air pump will cause the inhalation tube to absorb the smoke and excrete it through the air pump to avoid the smoke affecting the field of vision.Ensure that the field of vision is clear and the guarantee surgery can be performed smoothly.

Description

technical field [0001] The invention relates to an electric knife, more specifically, it relates to a laparoscopic electric knife. Background technique [0002] When surgery is performed in the abdominal cavity, the doctor will continue to inflate the abdomen to make the abdominal cavity bulge up for the operation, and then insert special surgical instruments into the abdominal cavity for surgery, such as electric knife and camera lens. The electric knife is generally used to cut some adhesions in the abdominal cavity, but smoke will be generated during use, which will blur the picture taken by the camera, interfere with the surgical field of view, and make it difficult for doctors to observe the situation in the abdominal cavity. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a laparoscopic electrosurgical unit capable of discharging smoke so as not to affect the visual field. [0004] In ...
