Abstract

The invention discloses a clip applier, and belongs to the technical field of medical devices. The clip applier comprises a driving mechanism, a triggering mechanism, a switching mechanism and a rotating shell, wherein the driving mechanism comprises a driving motor and a driving gear, the triggering mechanism is used for triggering a nail conveying mechanism, a sliding sleeve of the switching mechanism is arranged on the triggering mechanism in a sleeving mode and can slide relative to the triggering mechanism, and therefore, the switching mechanism has a triggering state and a jaw angle adjusting state. When the switching mechanism is in the jaw angle adjusting state, the rotating shell can be driven by the driving motor to rotate so as to adjust the jaw angle of the clip applier, and when the switching mechanism is in the triggering state, the rotating shell is locked so as not to rotate. The clip applier can be flexibly switched between the nail conveying mechanism and the jaw angle adjusting mechanism, so that the driving motor is fully utilized as a power source for triggering of the triggering mechanism and rotation of the rotating shell, the structure is compact, the operation is easy, the automation degree is high, and the jaw angle of the clip applier can be flexibly adjusted.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a clip applier. Background technique [0002] With the rapid development of medical technology, the maturity of minimally invasive surgery is getting higher and higher. It has the advantages of small trauma area and fast postoperative recovery, so it is more and more applied to various treatment plans. The hemostatic clip is an important part in minimally invasive surgery. It is mainly used for hemostasis on tissues with traumatic surfaces. The existing hemostatic clips are divided into titanium alloy hemostatic clips and polymer hemostatic clips according to different materials. [0003] The clip applier is a device that releases and clamps tissue clips. According to whether multiple loading of hemostatic clips is required, clip appliers are divided into single-shot clip appliers and multi-shot clip appliers. Existing clip appliers generally include a handle, a work...
