Abstract

The invention discloses a separable bracket pushing system which is used for pushing a bracket into a diseased part of a human body. The separable bracket pushing system comprises a separable bracket pusher and a fixer, wherein the separable bracket pusher comprises a pusher main body, an outer sleeve and two pull rings; the pusher main body comprises a pusher head, a pusher middle part and a pusher tail; a line guide passage is arranged along the central axis of the pusher head, the central axis of the pusher middle part and the central axis of the pusher tail; the outer walls of two ends of the pusher middle part are respectively coated with an annular metal layer; the outer sleeve is shaped as a hollow tube; the tail of the outer sleeve is symmetrically separated into two parts along the axial direction; the two separated parts are respectively connected with the two pull rings; two longitudinal separation lines are reserved at the junction line of the two separated parts; the fixer comprises an endoscope fixer and a pusher fixer; the endoscope fixer is used for fixing an endoscope, and the pusher fixer is used for fixing the pusher main body in an endoscopic biopsy hole of the endoscope.

Description

technical field [0001] The invention relates to a splittable stent pushing system, in particular to a splittable stent pushing system used in conjunction with an endoscope. Background technique [0002] At present, placing stents in the human body through endoscopy has become the main method for treating many malignant and benign lesions. Since the stent came out, it has been recognized by the medical profession for its obvious therapeutic effect and low complication rate. [0003] When the stent is placed, in order to ensure that the stent is accurately released in the lesion, the assistant and the endoscopist must cooperate to control the relative movement of the stent and the overtube, and must be carried out under endoscopic or X-ray monitoring. During the process of releasing the stent , often causes relative displacement between the stent and the outer tube, and a little carelessness will cause the released stent to deviate or even fall off, resulting in failure of th...
