Abstract
The utility model in particular relates to a guidewire transmitter which assists to plant a canal into a human body. The transmitter includes an injector and an auxiliary pin case. The injector is movably arranged on the side wall of the auxiliary pin case and the top part of the auxiliary pin case is provided with a strip cut along the length direction of the auxiliary pin case. One end of the auxiliary pin case is sleeved with a slide head and the other end is provided with an expansion head. The slide head is connected with a puncture pin and the puncture pin passes through the auxiliary pin case and transverses out from the inner hole of the expansion head. The upper part of the slide head is provided with a transmitting opening which is provided with a one way valve. A channel is formed between the transmitting opening and the puncture pin in the body of the slide head. The channel is communicated with the inner hole of the puncture pin. After adopting the technical scheme, as the puncture pin and the expansion head are arranged on the auxiliary pin case together, the puncture pin utilizes the expansion head to realize expansion under the situation of no need to pull out after puncturing into the human body when in use, thus having high puncture efficiency and reducing the operation steps.
Description
Technical field:
This utility model relates to the armarium technical field, refers in particular to a kind of Silk-guiding lead-in device of subsidiary conduit implant into body.
Background technology:
At present owing to exist not enough on the Silk-guiding lead-in device tool structure that clinical medicine uses, cause conduit implanted prosthetics step loaded down with trivial details, its puncture needle uses with the expansion head is independent separately, operating process lunges human body to puncture needle earlier, seal wire is slowly led in the human body through puncture needle in the middle of the hollow syringe, then the hollow injection device is extracted out along seal wire together with puncture needle, will expand and after seal wire lunges human body, pull out, at last conduit is injected in the human body along seal wire, pull out seal wire.Above-mentioned steps is loaded down with trivial details, and one-time puncture and expansion can not be finished simultaneously.
Summary of the invention:
The purpose of this utility model is in order to solve the shortcoming of above-mentioned prior art, a kind of Silk-guiding lead-in device that can finish one-time puncture and expansion simultaneously to be provided.
For achieving the above object, the technical scheme that this utility model provides is: a kind of Silk-guiding lead-in device of subsidiary conduit implant into body, it includes syringe and auxiliary needle cylinder, injector activity is arranged on the sidewall of auxiliary needle cylinder, the top of described auxiliary needle cylinder has the stripe shape otch along its length direction, one end of auxiliary needle cylinder is with slide head, the other end is provided with the expansion head, slide head is connected with puncture needle, puncture needle passes auxiliary needle cylinder and passes from the endoporus of expanding head, and the top of slide head is provided with introducing port, and this introducing port is provided with check valve, introducing port forms passage between the puncture needle in the slide head body, and this passage communicates with the puncture needle endoporus.
Also be provided with shop bolt on the slide head, on the urceolus of auxiliary needle cylinder, be processed with the counterbore that cooperates with shop bolt.
Shop bolt and slide head pass through interference fit.
After adopting technique scheme, puncture needle utilizes the expansion head to realize expansion under situation about need not pull out after lunging human body during use with being arranged on the auxiliary needle cylinder because puncture needle and expansion are first, puncture efficient height, reduces operating procedure.
Description of drawings:
Fig. 1 is the cutaway view of auxiliary needle cylinder part of the present utility model;
Fig. 2 is the three-dimensional exploded view of Silk-guiding lead-in device of the present utility model.
The specific embodiment:
Shown in accompanying drawing 1～accompanying drawing 2, this Silk-guiding lead-in device mainly is made up of two parts, be syringe 1 and auxiliary needle cylinder 2, syringe 1 is arranged on the sidewall of auxiliary needle cylinder 2, and it can be pulled up from auxiliary needle cylinder 2, effectively save production cost, the top of auxiliary needle cylinder 2 has stripe shape otch 3 along its length direction, and being with in the tube can be along the slide head 4 of its length direction slip, the bottom of slide head 4 is connected with puncture needle 5, puncture needle 5 can slide with slide head 4, and an end of auxiliary needle cylinder 2 is provided with expansion 6, and puncture needle 5 passes auxiliary needle cylinder 2 and passes from the endoporus of expansion 6, the top of slide head 4 is provided with introducing port 7, this introducing port 7 is provided with check valve 8, and introducing port 7 forms passage 9 between the minute hand 5 in slide head 4 bodies, and this passage 9 communicates with the endoporus of puncture needle 5.Slide head 4 is provided with shop bolt 10 in addition, this shop bolt 10 passes through threaded engagement with slide head 4, on the front-end and back-end of the urceolus of auxiliary needle cylinder 2, be processed with the counterbore 11 that cooperates with shop bolt 10, control the displacement that slidably reciprocates of puncture needle 5 by shop bolt 10.
