High frequency electric operating knife with fiber probe

Abstract

The invention relates to the medical instrument and tumour treatment field, and relates to a novel medical high frequency electric operating knife with a fiber probe; the intelligent electric operating knife main comprises a host integrating and controlling the high frequency electric operating knife and controlling a Raman light spectrum, an electric operating knife handle, an electric operating knife electrode, the fiber probe and a display, a patient electrode plate, and a pedal switch; compared with a conventional high frequency electric operating knife, the fiber of the electric operating knife is arranged on the inner side of the front end of an electrode head; the fiber probe transfers laser to the electrode tip of the high frequency electric operating knife, thus capturing high frequency electric operating knife terminal tissue or cell Raman light spectrum signals in real time, and automatically analyzing and monitoring the signals; in usage, the high frequency electric operating knife can monitor tissue and cell Raman light spectrum in the high frequency electric operating knife notch in real time, and can analyze the spectrum signals so as to obtain tissue and cell canceration state information of the present operation position; the high frequency electric operating knife can identify tumor and normal tissues in real time in a operation, thus helping a doctor to accurately cut off the canceration tissue, and preventing excess resection from affecting tissue organ functions.

Description

technical field [0001] The invention belongs to the field of medical equipment and tumor treatment. It relates to a new type of medical intelligent surgical electric knife, and specifically relates to a high-frequency surgical electric knife with an optical fiber probe. The present invention adds a Raman optical fiber probe design on the basis of the original high-frequency surgical electric knife. A medical surgical electric knife that can intelligently identify tumor tissue and normal tissue by detecting the difference of Raman spectrum in real time is prepared. The intelligent surgical electric knife of the present invention can quickly diagnose benign and malignant during operation. Background technique [0002] Surgery is one of the main treatment methods for malignant tumors. It uses instruments such as scalpels, scissors, and needles to perform local operations on the human body to remove diseased tumor tissues and repair damage to treat diseases. It has been more t...

Problems solved by technology

However, in clinical practice, due to the different tumor growth sites, it is difficult to maintain a balance between negative resection margins and preservation of organ functions. At the same time, it is difficult to accurately distinguish the boundary between tumor tissue and normal tissue with the help of doctors' experience and naked eye observation. Once there is residual tumor with positive resection margin, it will bring great difficulties to the follow-up treatment and affect the prognosis of the patient.

However, current surgical electrosurgical units do not have the function of identifying tumors in real time
