Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a film-shaped pressure sensor fixing mechanism and a urethra endoscope device. Background Art

[0002] Urethral endoscopes are the most commonly used surgical instruments in urology. Common types include cystoscopes, resectoscopes, plasmascopes, laser enucleation scopes, etc. They are widely used in urethral cystoscopy, prostatectomy, and bladder tumor resection. Due to its complex structure and the need to take into account the patency of liquid perfusion, the diameter of the endoscope is generally large, which has a greater squeezing effect on the patient's posterior urethra and prostate during surgery. If the operation time is long, the operation is rough, or the patient's urethra is small, it may cause serious complications such as urethral sphincter injury and urethral mucosal tearing. Therefore, real-time monitoring of the pressure in the posterior urethra during surgery can effectively avoid postoperative urinary incontinence and urethral stenosis. However, when a pressure sensor is currently installed on the urethral endoscope for pressure monitoring, there is a lack of a fixing mechanism for the pressure sensor, and there is a problem that the pressure sensor on the urethral endoscope is easy to slide and fall off during surgery.
