Repeating clamp applicator

Abstract

The invention belongs to the technical field of medical instruments, and in particular relates to a continuous clip applier. Aiming at the problem that the continuous clip applier in the prior art can only be better applied to metal tissue clips, the present invention provides a continuous clip applier, which includes a clip applier housing, and a push rod connected to the clip applicator. A pincer head is provided on the clamp housing and one end of the pincer head push rod. Moving the pincer head push rod can drive the pincer head to open or clamp. A first feed mechanism and a second feed mechanism are provided, the drive handle pushes the propulsion structure into the first feed space through the first feed mechanism, and the drive handle pushes the propulsion structure into the first feed space through the second feed mechanism. In the binary feed space. When the tissue clip is pushed out, the present invention can effectively reduce the range of the tissue clip’s automatic bounce action, and then use the second feeding mechanism to slowly clamp until it is completely closed, so it is more suitable for the automatic bounce when ejected tissue clips.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and in particular relates to a continuous clip applier. Background technique [0002] A clip applier is a surgical instrument used to clamp tissue clips during surgery. However, most of the clip appliers in the prior art are single-shot clip appliers, that is, tissue clips must be reinstalled at the clip head after each clip application, which results in lower operation efficiency. [0003] In response to this problem, people have also carried out exploration and research in long-term production and life practice. For example, a Chinese utility model patent discloses a continuous clamp applicator [Application No.: 201820962819.X]. The utility model patent includes a push handle , a pipe rod and a pincer head mounted on the front end of the pipe rod, it is characterized in that it also includes a push-pull rod driven by a push handle, a feeding device and a storage compartment, and th...

Problems solved by technology

[0004] However, in the actual use process, it is found that this kind of clip applier can only be better applied to metal tissue clips, such as titanium clips, because the metal can self-maintain its shape after deformation, while the plastic tissue clip There will be a large automatic pop-up action when it comes out to the position of the clip applier jaw, which will bring inconvenience to the medical staff during the operation
