Multipurpose laser endoscope

Abstract

The invention discloses a multipurpose laser endoscope, which comprises an endoscope channel, an optical fiber-electrode common channel and a front handle body with a handle, wherein the endoscope channel and the optical fiber-electrode common channel are fixedly connected; the outer parts of the endoscope channel and the optical fiber-electrode common channel are fixedly provided with the front handle body; the front handle body is provided with an elastic sealing mechanism communicated with the optical fiber-electrode common channel; the endoscope channel on the rear end of the front handle body is provided with a sliding support; the sliding support is provided with an electrode locking button, an optical fiber locking button, an optical fiber leading hole and an optical fiber leading channel communicated with the optical fiber leading hole; the sliding support is connected with a rear handle body; the endoscope channel is connected with an endoscope interface after passing through the sliding support; the endoscope is provided with an endoscope adapter substitute. According to the endoscope, the assemblies of other different brands of endoscopes can be used in order to realize a purpose that the endoscopes can be mutually replaced, the functions of a resectoscope and the endoscope are realized by the optical fiber-electrode common channel and an energy platform interface, and the multipurpose laser endoscope is suitable for different optical fibers and electrodes.

Description

technical field [0001] The invention belongs to the technical field of medical instruments and relates to a multipurpose laser endoscope. Background technique [0002] Transurethral surgery is currently the best surgical method for minimally invasive treatment of various diseases in urology, such as benign prostatic hyperplasia, bladder tumor, bladder stones, urethral stricture, etc., and all these operations must be completed with the help of endoscope. At present, there are many kinds of endoscopes used for transurethral surgery. According to the different surgical methods, they can be divided into monopolar resectoscopes, bipolar plasma resectoscopes, laser mirrors suitable for thin optical fibers and direct light output, suitable for Laser mirror with thick optical fiber and side light. [0003] These endoscopes currently used have the following disadvantages: 1) the functions are single and cannot be exchanged with each other, so several expensive endoscopes must be pu...

AI Technical Summary

Problems solved by technology

[0003] These endoscopes currently used have the following disadvantages: 1) the functions are single and cannot be exchanged with each other, so several expensive endoscopes must be purchased to carry out the above-mentioned operations, which significantly increases the operation cost; When it is necessary to change the surgical method during the operation, the entire set of surgical instruments must be replaced, which brings great inconvenience to the operator; 2) Speculums of different brands cannot be used universally, which often leads to repeated purchases and waste; 3) Often due to Due to the incompatibility between the functions of various endoscopes, the entire set of surgical instruments must be replaced, which brings great inconvenience to the operator; 4) Various optical fibers cannot be used on the same instrument due to different diameters. use

[0004] In addition, the currently used laser mirrors also have the following defects: due to the unreasonable design of the water flow channel, the surgical field of view is unclear, which increases the difficulty of the operation and the operation time. Therefore, the operator can only move the mirror sheath continuously to make the mirror sheath rub against the urethra repeatedly, which greatly increases the incidence of urethral edema and urethral stricture.
