经尿道前列腺切除术(TURP)已成为治疗良性前列腺增生症最常用的手术方法,但有时会发生增生前列腺外科包囊穿孔或静脉窦破裂出血等并发症,作者根据前列腺增生的组织和包囊两者在组织结构上的不同而具有不同的导电性能这一特点,设计了一台电子计算机监测系统,成功地解决了此问题。原来前列腺外科包囊主要由纤维组织所组成,质地致密,含细胞外液较少,导电性差,而增生的前列腺组织,纤维组织成份较少,而细胞外液及电解质含量相对较多,故具有良好的导电性能,作者利用这种明显的差异,将计算机监测装置与电切镜精巧地连接起来,在手术过程中,当电切镜的电切环接触到包囊时,监测系统立即发出警报声音,同时电切镜在0.4秒内自动切断电源,停止工作,从而避免发生前列腺包囊穿孔或静脉窦破裂出血的并发症。
Transurethral resection of the prostate (TURP) has become the most commonly used surgical treatment of benign prostatic hyperplasia, but sometimes complications such as peritumoral prostatic cyst perforation or venous sinus hemorrhage occur, the author according to the organization of benign prostatic hyperplasia and cysts two In the organizational structure of different and have different conductivity of this feature, the design of a computer monitoring system successfully solved the problem. The original prostate surgical cysts mainly composed of fibrous tissue, dense texture, containing less extracellular fluid, poor conductivity, and hyperplasia of prostate tissue, fibrous tissue less, and the extracellular fluid and electrolyte content is relatively large, it has Good electrical conductivity, the authors use this obvious difference, the computer monitoring device and resectoscope compact link, during the operation, when the resectoscope loop contact with cysts, the monitoring system immediately issued an alarm Sound, while resectoscope in 0.4 seconds automatically cut off the power, stop working, so as to avoid the complications of prostate capsule perforation or venous sinus bleeding.
