In order to solve the problems of the technologies described above, the invention discloses a kind of Medical endoscope hemostasis device, comprise connecting successively ground front hand grip assembly, back handle assembly and piercing assembly;
Described front hand grip assembly comprises front hand grip body and the outer tube that connects the front hand grip body;
Described back handle assembly comprises the inner tube of threeway handle and connecting tee handle, and the inner tube other end is provided with soft indwelling tube, and the threeway handle comprises side path and primary path;
Described piercing assembly comprises piercing needle, push rod and the afterbody hands handle that connects successively;
Described inner tube is positioned at outer tube inside, piercing needle and push rod be positioned at threeway handle and inner tube inner and with the inner tube matched in clearance, terminal airtight cooperation of piercing needle and soft indwelling tube, piercing needle and push rod are communicated with the side path of threeway handle with the gap of inner tube.
Among the present invention, the part that described threeway handle connects the afterbody handle adopts the female Luer respective outer side edges mutually.
Among the present invention, indwelling tube can be the flexible plastic conduit, do not scratch the risk of blood vessel, the flexible plastic conduit can be retained in the long period in the blood vessel, thereby further diagnose and treat through conduit, as carry out the angiography of cirso-through conduit, further understand the scope of lesion vessels, degree; And under x-ray monitors, treat, can be so that lesion vessels sclerosis thromboembolism more thorough and can avoid minute risk of thromboembolism isotonic thromboembolism.Piercing needle puncture is withdrawed from the metal puncture syringe needle after entering in diseased region such as blood vessel, the cyst immediately, the plastics indwelling tube is retained in the diseased regions such as blood vessel, cyst.The metal needle that avoided because vomiting etc. caused scratches blood vessel and causes dead danger.
Application of the present invention includes but not limited to: 1. by endoscope to esophagus, stomach at the bottom of injection of varicose vein with sclerosing agent, tissue glue and other medicines; 2. carry out drug injection and the on a small quantity suction of liquid puncture into the diseased regions such as blood vessel, cyst by endoscope after.
Beneficial effect: use injection device under the medical endoscope of the present invention, structure is ingenious, puncture by piercing needle can be brought the front end flexible pipe in the pathological tissues into, then extract hard piercing needle out, indwelling tube is retained in the pathological tissues, then carry out the operations such as fluid injection, can not cause the risk of scratching blood vessel in the whole operating process, indwelling tube is softer simultaneously, can be retained in the long period in the human body, thereby provide enough operating times to the doctor, thus, average doctor also can check in the situation of pressure at leisure not having.
