Detailed Description
In order that the above objects, features and advantages of the present invention can be more clearly understood, there will now be described in detail, with reference to the accompanying drawings, a non-limiting detailed description of the present invention.
As shown in fig. 1 to 4, the endoscopic puncture needle of the present embodiment includes a needle 1, a protective sheath 2 for housing the needle 1, and a bellows 12, one end of the bellows 12 is communicated with the syringe through a first connector 14, and the other end is communicated with the needle 1 through a second connector 13; the first connector 14 is inserted into the sheath 2 and is fixedly connected thereto, and the needle 1 is movable to extend out of the sheath 2. The first joint 14 is a cylindrical structure with a through hole, one end of the first joint 14 is inserted into the corrugated pipe 12 and fixedly connected with the corrugated pipe, and the other end of the first joint is connected with an injector; the second joint 13 is a structure with one end sealed and hollow inside, and the sealed end is provided with an insertion hole 19, the open end of the second joint 13 is inserted into the corrugated pipe 12 and fixedly connected with the same, the needle 1 extends into the second joint 13 through the insertion hole 19, and the second joint 13 is inserted into the inner sleeve 15 and fixedly connected with the same. A stop 10 protrudes from the inner wall of the end of the protective sleeve 2 remote from the first connector 14, and the inner sleeve 15 is blocked between the stop 10 and the first connector 14. The protective sleeve 2 is made of transparent materials.
The endoscope puncture needle further comprises a telescopic mechanism 17, the telescopic mechanism 17 comprises a spring 16 and an inner sleeve 15, the inner sleeve 15 is arranged in the protective sleeve 2 and can slide along the length direction of the protective sleeve 2, an annular groove 18 is formed between the protective sleeve 2 and the corrugated pipe 12, the spring 16 is positioned in the annular groove 18 and sleeved on the corrugated pipe 12, one end of the spring 16 is connected with the protective sleeve 2, the other end of the spring is connected with the inner sleeve 15, and the protective sleeve 2 is provided with a fastener for fixing the inner sleeve 15; the inner sleeve 15 is fixedly connected to the second connector 13. The fastener is bolt 4, and bolt 4 and protective sheath 2 threaded connection, and interior sleeve pipe 15 surface is equipped with the locating hole, and after syringe needle 1 shrink back protective sheath 2, bolt 4 can insert in the locating hole. The inner wall of the protective sleeve 2 is provided with a clamping hole, the outer wall of the inner sleeve 15 is provided with an elastic part 21, and after the needle head 1 extends out of the protective sleeve 2, the elastic part 21 is clamped in the clamping hole under the action of elasticity.
