Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

As shown in Figures 1-4, this embodiment provides a multifunctional combined needle knife, including a needle body 1, a shovel surface 2 and a handle 3 integrally connected at the head end and the tail end of the needle body 1, and the handle 3 The outer wall of the needle body is provided with a symmetrical planar structure 4, on which several convex points 5 are fixed, which is convenient to hold, and the setting of the convex points 5 improves the stability of holding, and the needle body 1 is provided with an injection channel 6, so that The shovel surface 2 is provided with an injection port 7 communicating with the injection channel 6, and the handle 3 is provided with a mounting hole 8 communicating with the injection channel 6, and the mounting hole 8 is plugged with the injection end of the syringe, and the injection port is injected through the syringe. Drugs are injected into the channel 6 to anesthetize or give medicine to the diseased tissue area. At the same time, if the lesion area has too much fluid, the syringe can also extract the fluid. The insert 9 can be slidably inserted into the injection channel 6 and installed In the hole 8, the insert 9 is used to hook the diseased tissue. After the drug injection is completed, the insert 9 is inserted into the injection channel 6. The insert 9 includes an integrally connected guide rod 91, an insertion column 92 and a fixing cap 93 , the guide rod 91 is in close contact with the inner wall of the injection channel 6, the insertion column 92 is in close contact with the inner wall of the installation hole 8, the fixing cap 93 is socketed with the outer side wall of the end of the handle 3, and the insertion part 9 is fixed through the fixing cap 93.
