Embodiment Construction

[0014] The present invention will be further described through specific embodiments below in conjunction with the accompanying drawings. see figure 1

[0015] In the figure, a large-diameter injection syringe (1), a small-diameter injection syringe (2), and a fixed insert (3) are included. The special syringe for tissue glue injection under endoscope according to claim 1, characterized in that the large-diameter injection syringe (1) and the small-diameter injection syringe (2) are sleeve-type structures. A special syringe for tissue glue injection under endoscope according to claim 1, characterized in that the pintle of the small-diameter injection syringe (2) is higher than the pintle of the large-diameter injection syringe (1). When in use, the tissue glue pumping channel sucks in medicine with a small aperture inside, and the needle plug is higher than the other channel pin plug. The hypertonic drug is pumped into the other space of the syringe barrel from another apert...

Abstract

Endoscopic tissue glue injection is an effective method for gastric fundal varices treatment and requires a 'sandwich' method, and hyperosmotic drugs need to be injected rapidly and powerfully after tissue glue injection. At present, injectors of 2 ml have very high requirements for endoscopic treatment operators, cooperative persons and medicine suction nurses in use, the needle plugging risk also exists during injector change, and the endoscopic treatment demand cannot be very well met. At present, no reasonable special injector exists in the market. The invention provides an injector special for endoscopic tissue glue injection. The injector special for endoscopic tissue glue injection comprises a large-diameter injection needle cylinder (1), a small-diameter injection needle cylinder (2) and a fixing insertion piece (3). The injection is simple and convenient to use, prevents tissue glue from being in contact with air, reduces the risk that an injection needle is plugged by solidifying tissue glue and can meet the demand for endoscopic tissue glue injection.

Description

technical field [0001] The invention relates to a medical device, in particular to a special syringe for tissue glue injection under an endoscope. It belongs to the field of medical equipment. Background technique [0002] Endoscopic tissue glue injection is an effective method for the treatment of gastric varicose veins. The tissue glue injection requires a "sandwich" method, and the injection of hypertonic drugs after the tissue glue injection requires rapid and powerful injection. At present, the use of 2ml syringes has high requirements for endoscopic treatment operators, coordinators, and medicine pumping nurses. There is still a risk of needle blockage when changing syringes, which cannot well meet the needs of endoscopic treatment. There are currently no reasonable dedicated syringes on the market. The Chinese patent with the application number CN201710349351.7 uses the structural design of negative pressure vacuum to improve the operability of the syringe, but it d...
