Problems solved by technology

During the process of entering the human body, the bendable section is retracted into the telescopic sheath, and the rigid telescopic sheath will also increase the discomfort of the patient, and even cause the patient's muscle spasm, so that the catheter can be held tightly so that it cannot enter the urinary catheter smoothly
In the same way, the use of a stretchable sheath outside the rigid section will increase the overall diameter, so that when inserted into the urethra of children or patients with ureteral stricture, the resistance received is greater, which is more likely to cause muscle spasm in patients, or to the patient's urethra. cause some damage
[0008] To sum up, the existing flexible and hard ureteroscopes not only did not solve the problem of causing discomfort or even spasm in patients, but also had the problems of increased outer diameter and complicated lens direction control.

Abstract

The invention discloses a soft-hard integrated composite endoscope. The endoscope includes a working part and an operation part. The work part includes an insertion tube made from soft materials, therear end of the insertion tube is connected with the operation part, a soft-hard conversion channel is formed in the insertion tube, and the soft-hard conversion channel is internally provided with ahard insert. The operation part includes a shell, and the shell is internally provided with a soft-hard conversion drive mechanism moving in the soft-hard conversion channel. The soft-hard integratedcomposite endoscope can not only conveniently enter the human body, but also effectively improve patient's experience, alleviate the discomfort of the patient and avoid the spasm of the patient.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, in particular to a composite endoscope integrating soft and hard. Background technique [0002] Endoscopy is a detection instrument that integrates traditional optics, ergonomics, precision machinery, modern electronics, mathematics, and software. It usually has image sensors, optical lenses, light source lighting, and mechanical devices. It can pass through natural channels or through surgery. Small incisions are made to enter the body. Classified according to the different parts of the endoscope, it can be divided into ENT endoscope, oral endoscope, dental endoscope, neuroscope, urethral cystoscope, resectoscope, laparoscope, arthroscope, sinus mirror, laryngoscope, etc. . [0003] Existing endoscope has two kinds of hard mirror and soft mirror. Hard mirrors can generally enter the human body better, but hard tubes will increase the patient's discomfort and even cause muscle spas...
