A Simple Tissue Clip Continuous Clip Applier

Abstract

The invention discloses a simple tissue clip continuous clip applier, which belongs to the field of clip applicators. The continuous clip applicator of the present invention comprises a pincer head control mechanism, a push clip control mechanism and a pincer rod. The clip control mechanism includes a push clip operating handle, a clip feeding push rod, a storage clip clip and a clip feeding push piece. The clamping action and pushing action of the continuous clamping clamp are divided into two control actions to complete. The design of the storage clamp head is adopted to realize the integrated design of the clamp head and the storage chamber, and the storage clamp head is used to move back and forth to make the storage clamp The extension and contraction of the clamp head in the clamp rod drives the opening or closing of the two clamp arms; the use of the clamp feeding push piece realizes the synchronous forwarding of the tissue clips in the storage clamp head; through the cooperative cooperation of the clamp head control mechanism and the push clamp control mechanism , Realize the burst operation of the clip applicator, the structure design of the clip applier is simple and compact, the push clip and clip closing operation are stable and reliable, the use is flexible and convenient, and the production cost is low.

Description

technical field [0001] The invention relates to a medical clip applicator, more particularly, to a simple tissue clip continuous hair clip applier. Background technique [0002] Tissue clip is a new type of surgical instrument that has been widely adopted and used by medical institutions around the world in the last ten years. It is mainly used to close or ligate tubular tissues, such as blood vessels and bile ducts, in minimally invasive surgery. like figure 1 As shown, it is mainly composed of two clamping arms 1', the two clamping arms 1' are connected by a rotating part 2' to form a clamping body with a substantially "V" shape, and a hook is provided at the end of one clamping arm 1' 4', the end of the other clip arm 1' is provided with a buckle groove 5', when the tissue clip is closed, the buckle 4' is buckled into the buckle groove 5' to realize the stable closure of the tissue clip. [0003] The clip applier is a commonly used instrument for closing the above-menti...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to overcome the disadvantages of the existing sequential tissue clip applicator such as complex structure design and poor operation stability, and provide a simple tissue clip continuous clip applier. By adopting the technical solution of the present invention, the The clamping action and pushing action of the continuous clamping clamp are divided into two control actions to complete. In the clamp head control mechanism, the design of the storage clamp head is adopted to realize the integrated design of the clamp head and the storage chamber. Move back and forth to make the storage clamp head expand and contract in the clamp rod to drive the first clamp arm and the second clamp arm to open or close; The clips are conveyed forward synchronously; through the cooperative cooperation of the clamp head control mechanism and the push clamp control mechanism, the continuous operation of the clip applicator is realized. Flexible and convenient to use, low production cost
