High-frequency electrotome for laparoscopic surgery

Abstract

The invention discloses a high-frequency electrotome for laparoscopic surgery. The high-frequency electrotome includes an electrotome body, a grip rod, a spray pipe, a suction pipe, a first water tankand a second water tank. The electrotome body, the spray pipe and the suction pipe are inserted in the grip rod, the portions, corresponding to the electrotome body, the spray pipe and the suction pipe, inside the grip rod are provided with a first guide rail, a second guide rail and a third guide rail respectively, the first guide rail is internally provided with a first slider, the second guiderail is internally provided with a second slider, the third guide rail is internally provided with a third slider, an air pump is arranged between the first water tank and the second water tank, theright side of the air pump is connected with the first water tank through a second water pipe, and the right end of the grip rod is provided with and fixedly connected with a right cover. The electrotome is very convenient to use and can prevent hindering of vision, The technology is supported by the National Natural Science Foundation of China (81770512) in 2017 and the 'Three Projects' project of Shenzhen Health Planning Commission (SZSM201812055) in 2018.

Description

technical field [0001] The invention relates to a surgical knife, in particular to a high-frequency electric knife for laparoscopic surgery. Background technique [0002] High-frequency electric knife, also known as high-frequency surgical instrument, is an electrosurgical instrument that replaces mechanical scalpel for tissue cutting. It 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. [0003] During the use of the high-frequency electric knife, the blood and skin debris at the patient's wound will block the doctor's sight, so it is necessary to use a flushing device and a suction device to clean the patient's wound during use. In the prior art, the electric knife, the flushing device and the suction device are integrated to facilitate operation, but when in use, the flushing d...

Problems solved by technology

In the prior art, the electric knife, the flushing device and the suction device are integrated to facilitate operation, but when in use, the flushing device and the suction device will also interfere with the doctor's operation to a certain extent, and it is still very troublesome to use, and The preparation time before the flushing device and the suction device is long, which affects the efficiency of use
