A multi-purpose laser endoscope

Abstract

The invention discloses a multi-purpose laser endoscope, which comprises a speculum channel, a common channel of an optical fiber-electrode and a front handle body with a handle, the channel of the speculum and the common channel of the optical fiber-electrode are fixedly connected, the channel of the speculum and the common channel of the optical fiber-electrode are fixedly connected. A front handle body is fixed outside the electrode common channel, and the front handle body is provided with an elastic sealing mechanism that communicates with the optical fiber-electrode common channel. The electrode locking button, the fiber locking button, the fiber inlet and the fiber inlet channel connected with the fiber inlet, the sliding frame is connected with the rear handle body, the speculum channel is connected with the speculum interface after passing through the sliding frame, and the endoscope A sight glass adapter is installed on it. The endoscope can use the components of other endoscopes of different brands, which realizes the interchangeability of endoscopes, and not only realizes the functions of resectoscope and endoscope through the common channel of optical fiber-electrode and energy platform interface , and is applicable to 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...

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.
