One-piece stent implanter

Abstract

The invention discloses a one-piece stent implanter, including a front handle and a rear handle; the front end of the front handle is provided with an outer pipe whose top is flexibly connected with a cautery tip, the outer pipe is internally provided with a middle pipe and a stent; the rear handle includes a stainless steel pipe for supporting and an inner pipe positioned in the stainless steel pipe, the top of the inner pipe is fixedly connected to the cautery tip; one end of the middle pipe is mutually touched and connected with one end of the stent, while the other end of the middle pipe is mutually connected with the stainless steel pipe; one end of the stent is close to the cautery tip, with a certain gap kept; when the front handle is retreated along the stainless steel pipe, the outer pipe simultaneously retreats and separates from the cautery tip, positions of the middle pipe and the rear handle remain unchanged, and the stent is automatically released. The invention wherein the stent can be directly implanted into a nidus organ incised and an access from the outside to the nidus organ is established, so that other medical apparatuses and instruments can be continuingly used for removal (including other surgeries) of infectious agents or necrotic tissues, thus increasing comprehensiveness of surgeries and avoiding patients from suffering from repeated operations.
