一种经尿道手术用的多功能装置A multifunctional device for transurethral surgery

技术领域technical field

本实用新型涉及医疗用具技术领域，具体涉及一种经尿道手术用的多功能装置。The utility model relates to the technical field of medical appliances, in particular to a multifunctional device for transurethral surgery.

背景技术Background technique

经尿道腔镜手术是泌尿外科最常见的手术之一，尤其以经尿道输尿管碎石术最为常见，但目前存在以下几个问题：Transurethral laparoscopic surgery is one of the most common operations in urology, especially transurethral ureteral lithotripsy, but there are currently the following problems:

1、经尿道输尿管碎石术目前是一种常规手术，大部分基层医院均已开展，但初学者在输尿管硬镜自尿道进入膀胱过程中，镜头端容易损伤尿道；1. Transurethral ureteral lithotripsy is currently a routine operation, which has been carried out in most primary hospitals, but for beginners, when the ureteroscope enters the bladder from the urethra, the lens end is easy to damage the urethra;

2、经尿道输尿管碎石术，术中需持续泵入冲洗液，持续泵入的冲洗液会导致膀胱内压升高，需要及时引流出体外，保证手术顺利进行，目前尚无特制装置，一般使用F8-F12脑室引流管置入膀胱作为引流装置，但此引流装置存在术中引流速度不可控、引流不通畅、术中容易脱落等缺点，影响手术操作。2. Transurethral ureteral lithotripsy requires continuous pumping of flushing fluid during the operation. The continuous pumping of flushing fluid will increase the internal pressure of the bladder, and it needs to be drained out of the body in time to ensure the smooth progress of the operation. Currently, there is no special device. F8-F12 ventricular drainage tubes were used to insert into the bladder as a drainage device. However, this drainage device has disadvantages such as uncontrollable drainage speed, unsmooth drainage, and easy to fall off during the operation, which affects the operation.
