Catheter for colonoscopy with spraying powder hemostatic drug

Abstract

The invention discloses a catheter for a spraying powder hemostatic drug enteroscope. The catheter comprises a medicine bin, the left end of the medicine bin is provided with a discharge opening connector, a flow adjusting device is arranged on the discharging opening connector, an end cap is arranged at the right end of the medicine bin, the end cap is rotationally connected to the medicine bin, a feed inlet connector is arranged at the right end of the end cap, scale lines are arranged on the outer surface of the medicine bin, the inner side of the end cap is connected to one end of a connection rod, the connection rod is arranged parallel to the medicine bin, the other end of the connection rod is connected with one end of a grinding plate, the other end of the grinding plate is connected with a filter screen through a rotary shaft, the filter screen is round, the rotary shaft is arranged in the circle center of the filter screen, the edge of the filter screen is connected with the medicine bin, a baffle is fixed to the side face of the filter screen, and the baffle and the grinding plate are arranged on the right side of the filter screen. The catheter for the spraying powder hemostatic drug enteroscope can effectively prevent a sprayer from being blocked, guarantees the smooth hemostatic process, and is simple in structure and convenient to use.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a catheter for colonoscopy with spraying powder to stop bleeding. Background technique [0002] Separation, ligation, suture, and hemostasis are the four basic operations of surgery. The surgical operation under the electronic colonoscope is complicated, and intestinal wall tissue damage and bleeding occur from time to time. At present, electrocoagulation or noradrenaline and other liquids are mostly used to stop bleeding, but powder hemostatic drugs have a wide contact surface, a higher hemostasis rate, firm blood scabs, easy observation, and good stability. The fourth-generation plant polysaccharide hemostatic powder can still activate its own blood coagulation cascade reaction, form a physiological blood clot, and generate internal suction through water absorption and swelling, absorb formed components, and form a mechanical blood clot. However, powder hemostatic dru...

AI Technical Summary

Problems solved by technology

However, powder hemostatic drug particles are easy to adsorb to the wet tube wall, and because of the different sizes of powder hemostatic drug particles, the spray head is often blocked, resulting in equipment failure and hemostasis failure. Therefore, we propose a catheter for spraying powder hemostatic drug colonoscopy
