Numerical control filling type laparoscopic portal blood blocking instrument

Abstract

The invention provides a numerical control filling type laparoscopic portal blood blocking instrument which comprises a filling type laparoscopic portal blood blocking tape, a connecting tube with a one-way valve, a filling medium and an infusion pump with a digital control chip. The filling type laparoscopic portal blood blocking tape is connected to the connecting tube with the one-way valve, the filling medium is arranged in the infusion pump with the digital control chip, the infusion pump with the digital control chip is connected to the filling type laparoscopic portal blood blocking tape through the connecting tube with the one-way valve, and accordingly the filling medium is filled into the filling type laparoscopic portal blood blocking tape. The digital control chip is used for controlling infusion of the filling medium towards the filling type laparoscopic portal blood blocking tape.

Description

technical field [0001] The invention relates to the field of medical equipment, and more specifically, the invention relates to a digitally controlled filling type laparoscopic hepatic portal blood flow occlusion instrument. Background technique [0002] There are already domestic literatures (Zhu Xinsheng, Zhang Yuemin, Li Bohong, etc. Application of partial hepatic blood flow blocker in laparoscopic hepatectomy. Journal of Third Military Medical University, 2009, 29(14): 1447-1448; Lu Bangyu, Lu Wenqi, Cai Xiaoyong, et al. Application of laparoscopic hepatic portal blood flow blocker in partial hepatectomy. Chinese Journal of Endoscopy, 2005, 11: 982-983.) reported that in laparoscopic hepatectomy, few medical The center has developed various simple hilar blockers on the basis of using existing equipment, but they have not been widely recognized and promoted. The reason is that it is not easy to operate under laparoscopy, and some of the blockers are not complete, which ma...

AI Technical Summary

Problems solved by technology

A few domestic medical centers have introduced it, but it may also affect subsequent operations

[0004] All of the above-mentioned instruments use a solid bandage or blocking forceps to bind and clamp the hepatoduodenal ligament to achieve blood flow blocking, but it is not easy to perform the binding and clamping under the laparoscope. Blocking is not complete, so the blocking effect is not good; in addition, it needs to occupy an operation channel and a certain amount of intra-abdominal space, which may affect subsequent operations

Moreover, there is another important problem that none of them can be digitally and automatically controlled for its use, which has certain blindness and is not easy and fast to use.
