The Empirical Study On The Presacral Haemostatic Thumbtack Projector To Stop Massive Presacral Bleeding

Objectives: To devise and make the presacral haemostatic thumbtack projector that could be used to stop massive presacral bleeding quickly in clinic.Methods: 1. Devising and making the presacral haemostatic thumbtack projector and the thumbtack: On the basis of the mankind presacral camber, the projector is made of stainless steel, and the thumbtack is made of Ti-6Al-4V alloy. 2. The animal experiment: Dogs were used to build massive presacral bleeding model, according to the rectal cancer radical correction and scarification presacral venous plexus. The models were performed on 24 cases, and were divided into two groups(experimental group; EG and control group; CG). Thumbtacks fired through the new projector were used to control massive presacral bleeding in EG. Tradition thumbtacks were used in CG. The amount of bleeding, haemostasis time, the death rate related to the operation, the number of thumbtacks are compared in two group.Results: 1. Devising and making the presacral haemostatic thumbtack projector had been successfully achieved. 2. Haemostasis time was 12.25±10.69 seconds in EG, and it was 26.00±11.52 seconds in CG (p=0.01); EG have better haemostatic effect than CG (p=0.03); However, the results of the amount of bleeding, the death rate related to the operation, the numbers of thumbtacks in two group didn't have any statistical significance.Conclusions: The presacral haemostatic thumbtack projector is more quickly and has better therapeutic effect than tradition thumbtack in controlling presacral bleeding, and this new appliance could be used and advocated in clinic step by step.
