Intra-operative dissector with videography guiding function

Abstract

The invention relates to the field of surgical medical instruments, in particular to an intra-operative dissector with a videography guiding function. The intra-operative dissector is characterized by comprising a handle (3), an electrode (2), a power plug, a wire, a positioning recording assembly (8) and a control board (4). The intra-operative dissector has the advantages that the position of the electrode can be adjusted at will; a slot is formed, so that the electrode can be rapidly replaced with electrodes with different purposes during an operation; the positioning recording assembly is arranged, the operating track of a knife pen during the operation can be recorded, and data analysis and simulation can be carried out after the operation; a smoke guide tube is arranged, and multiple functions of exhausting smoke, extracting exudate, introducing argon and introducing cleaning fluid can be achieved through external connection with different kinds of equipment.

Description

technical field [0001] The invention relates to the field of surgical medical instruments, in particular to an intraoperative dissector with video recording and navigation functions. Background technique [0002] The intraoperative dissector, also known as the electrosurgical pen, is currently widely used in surgical operations and is an electronic surgical instrument that replaces mechanical scalpels for tissue cutting. [0003] The working principle of the electric knife pen is to pass the high-frequency current through the electrode to reach the target tissue, and the part close to the target tissue and the electrode is rapidly heated and vaporized by the high-frequency current. In the specific operation process, the functions of cutting and coagulation are respectively realized through the frequency change of the high-frequency current. [0004] In the prior art, none of the electrosurgical pens has the function of positioning and imaging, and cannot record the operatio...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, none of the electrosurgical pens has the function of positioning and imaging, and cannot record the operation trajectory of the knife pen during the operation, so it is difficult to perform data analysis and simulation after the operation

[0005] At the same time, in order to avoid cross-infection during use, the electric knife pen cannot be reused many times

However, the traditional fixed electrosurgical pen cannot replace the electrodes, so it is necessary to use multiple electrosurgical pens with different electrodes to complete certain operations, which adds unnecessary economic burden to patients.
