A urethral dilator with induction device

Abstract

A urethral dilator with a sensing device, comprising a urethral dilator for dilating the urethra, a dilator support rod for facilitating the entry of the urethral dilator into the urethra, a core pressure sensor for detecting the urethral pressure on the tip of the dilator support rod, and a urethral dilator for detecting The peripheral pressure sensor of the urethral pressure on the expansion device and the signal output end of the feedback core pressure and peripheral pressure, the core pressure sensor and the peripheral pressure sensor are connected to the signal output end through the controller, and the present invention reduces the operation cost. It reduces the risk of surgery, reduces the pain of surgery for patients, and can shorten the learning curve for doctors to learn, which is beneficial to the promotion of surgery.

Description

technical field [0001] The invention relates to a urethral dilator with an induction device. [0002] technical background [0003] Urethral stricture is a common disease of the urinary system. Urethral dilatation is an important method in the treatment of male urethral strictures, and some patients need regular urethral dilation for life. Traditional urethral dilation uses a metal urethral probe. The commonly used specification is F16-24. Under local anesthesia, probes of different diameters are sequentially inserted into the urethra starting from smaller models, and the diameter is gradually increased by violent tearing to achieve the expansion of the stricture ring of the urethra. The outer diameter of the second increase should not be too large, so as not to cause urethral function damage. [0004] In traditional surgery, doctors can only rely on experience to operate, and lack of awareness of the force of each part of the probe. When the progress of the probe along th...

AI Technical Summary

Problems solved by technology

[0004] In traditional surgery, doctors can only rely on experience to operate, and lack of awareness of the force of each part of the probe. When the progress of the probe along the urethra is blocked, it may be that the urethral stricture is encountered, or the probe may enter in the wrong direction. Blind end, if operated blindly, it is very easy to generate a false passage, and even cause adverse consequences such as urethral perforation, hematuria, urethral atresia, etc. Therefore, in the common outpatient treatment operations of urology, urethral dilatation is relatively complicated and requires high requirements for doctors treatment items

In the learning process of urethral dilatation, doctors lack relevant intuitive data support for the learning and use of instruments, so doctors have a long learning curve, which is not conducive to the promotion of surgical projects

[0005] In addition, during the expansion process, it is necessary to replace various types of expansion probes to complete the expansion, which increases the work intensity of doctors and increases the difficulty of device management.
