Described front hand grip assembly comprises front hand grip body and connects the outer tube of 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 threeway handle comprises side path and primary path;
Described piercing assembly comprises the piercing needle, push rod and the afterbody hands handle that connect 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 inner tube matched in clearance, the airtight cooperation of end 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.
In the present invention, the part that described threeway handle connects afterbody handle adopts female Luer respective outer side edges mutually.
In the present invention, indwelling tube can be flexible plastic conduit, do not scratch the risk of blood vessel, flexible plastic conduit can be retained in the long period in blood vessel, thereby further diagnose and treat through conduit, as carried out the angiography of cirso-through conduit, further understand the scope of lesion vessels, degree; And treat under x-ray monitors, the more thorough of lesion vessels sclerosis thromboembolism can be made and a point risk for thromboembolism isotonic thromboembolism can be avoided.Piercing needle puncture enters diseased region as after in blood vessel, cyst, exits immediately metal puncture syringe needle, and plastics indwelling tube is retained in to the diseased region such as blood vessel, cyst.Avoid causing dead danger because the metal needle that vomiting etc. causes scratches blood vessel.
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 drug; 2. after puncturing into the diseased region such as blood vessel, cyst by endoscope, carry out drug injection and the suction of liquid on a small quantity.
Beneficial effect: use injection device under medical endoscope of the present invention, structure is ingenious, puncture by piercing needle can be brought front end flexible pipe in pathological tissues into, then extract hard piercing needle out, indwelling tube is retained in pathological tissues, then carry out the operations such as fluid injection, in whole operating process, can not cause the risk of scratching blood vessel, indwelling tube is softer simultaneously, can be retained in the long period in human body, thereby provide enough operating times to doctor, thus, average doctor also can check at leisure in the situation that there is no pressure.
