Urethral dilator with sensing deVice

Abstract

A urethral dilator with a sensing deVice comprises a urethral dilatation deVice used for urethral dilatation, a dilator supporting rod, a core pressure sensor, a peripheral pressure sensor and a signal output end, wherein the dilator supporting rod makes the urethral dilatation deVice enter the urethra conVeniently; the core pressure sensor is used for detecting the urethral pressure borne by thetip end of the dilator supporting rod; the peripheral pressure sensor is used for detecting the urethral pressure borne by the urethral dilatation deVice; the signal output end is used for feeding back core pressure and peripheral pressure; the core pressure sensor and the peripheral pressure sensor are connected with the signal output end through a controller. The operation risk is reduced, the pain of a patient is relieVed during an operation, a learning curVe of a doctor can be shortened, and the urethral dilator is beneficial to popularization of the operation.

Description

Technical field [0001] The invention relates to a urethral dilator with a sensing device. technical background [0002] Urethral stricture is a common disease of the urinary system. Urethral dilation is an important method in the treatment of male urethral stricture, and some patients need to receive urethral dilatation regularly throughout their lives. Traditional urethral dilation uses metal urethral probes. The commonly used specification is F16-24. Under local anesthesia, probes of different diameters are sequentially inserted into the urethra starting from the smaller model, and the diameter is gradually increased by the method of violent tearing to achieve the expansion of the urethral stricture ring. The outer diameter of the second increase should not be too large to avoid damage to the urethral function. [0003] In traditional surgery, the doctor can only rely on experience to operate, and lacks awareness of the force of each part of the probe. When the probe is blocke...

Problems solved by technology

[0003] 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 di
