Fastening safety device of continuous sending clip applicator

Abstract

The invention discloses a fastening safety device of a continuous sending clip applicator, and a feeding device for deadlocking or opening of the continuous sending clip applicator. The continuous sending clip applicator includes a pushing handle, a pipe rod and a clip head arranged at the front end of the pipe rod. The pipe rod is internally provided with the feeding device, a push-pull rod and astorage bin. The fastening safety device includes a fixed part, a gear assembly and a safety shaft. The gear assembly is used for pushing a transfer piece to move; the gear assembly is arranged on the fixed piece through the safety shaft and rotates relative to the fixed piece; the safety shaft is used for deadlocking or opening of the gear assembly, the transfer piece is prevented from retreating back when the continuous sending clip applicator is used normally, and a drive piece can be prevented from pushing the transfer piece to go ahead due to misoperation, an opening / closing clip is prevented from entering the clip head, and clamping of the opening / closing clip by the clip head is prevented from being affected. The fastening safety device makes the use of the continuous sending clipapplicator safer, more reliable and smoother.

Description

technical field [0001] The invention relates to the technical field of medical instruments and equipment, in particular to a hair-withholding safety device for a continuous hair clamp applicator. Background technique [0002] Clip applier is a commonly used medical device, usually used in surgical operations, to clamp blood vessels and play a role in hemostasis, also known as hemostatic forceps. When the existing continuous clamp applicator pushes the closing clip in the storage bin, the feeding device and the push handle complete the actions of pushing the closing clip and clamping the closing clip respectively. During the operation, due to the installation distance between the feeding device and the pushing handle Close, it is easy to touch the feeding device, resulting in misoperation of the continuous clamping pliers, causing the feeding device to retreat, and the closing clip in the storage bin is loose to cause displacement, which affects the continuous use of the cont...
