Description

[0001] The present invention relates to an anti-slip structure unit for a clip applier and a clip applier having the slip prevention structure for the clip applier,

[0001] The present invention relates to a clip unit having a slip prevention structure for clip appliers and clip appliers having the slip prevention structure for clip appliers, It's about the Apple learner.

Medical clips may be used for gripping or resecting a human organ extending in the longitudinal direction, such as a blood vessel or cecum, during an intra-human surgical procedure. For example, clips are used to grasp, ligature, or bleed the appendix or blood vessels during an appendectomy procedure. Such a medical clip may be made of, for example, a resilient metal or polymer material. A number of clips may be sequentially placed on the apple lyre for ligation of a part of the body, such as a part of the blood vessels or cecum during the surgical procedure. And before using the clip, the Apple lyre may be sterilized or sterilized or left unattended for extended periods of time. If the Apple lyer is in this state, the physical properties, such as the elasticity of the clip placed inside it, can change, which can lead to the jaw unit placed at the end of the Apple lyre and cause the clip to separate during use. Also, since a plurality of clips are successively placed in the supply tube of the Apple Liaer, the clips placed on the rear side may change their physical properties over time. Thus, there is a need for a clip applier that maintains the physical characteristics of the clip before use and can be used stably in the surgical procedure.

U.S. Patent No. 7,316,696 discloses a polymeric material having first and second curved legs that are joined at their ends by a flexible hinge region and are movable from an open position to a closed position for gripping blood vessels between opposed inner surfaces of a curved shape A surgical clip is disclosed.

U.S. Patent No. 7,052,504 discloses a surgical clip applier comprising a drive device, a pair of opposing jaws, and an extension assembly disposed therebetween. The prior art teaches that the clip control component is actuated by the drive to continuously move the clip through the extension assembly so that the clip drive device disposed in the extension assembly is coupled to the jaw and the clip control component is disposed at the end of the extension assembly, The first clip control surface contacting the first end portion of the clip to cause the clip to rotate about the first end portion and the second and third control manifesting surfaces to engage the first, Discloses an automated supply surgeon clip applier that receives an end portion of a clip before the clip is moved to engage.

United States Patent Publication No. US 2014 / 0052157A1 discloses a handle portion; A body extending from the handle portion; A plurality of surgical clips disposed within the body; And a coarse unit arranged adjacent to an end of the body, for the application of a surgical clip for body tissues.

A number of clips may be inserted into the Apple lyre and placed on the jaw unit in turn to be used for ligation of the human body. It can be stored in the storage case for a long time before being inserted into the Apple lyre, and can be sterilized at high temperatures after insertion. And the elasticity of the clip during storage or disinfection may change, which may cause the clip to come off the jaw unit during use preparation or use for ligation, which may interfere with the operation. Therefore, a jaw unit having a structure for preventing slippage of such a clip needs to be developed.

The present invention has been made to solve the problems of the prior art and has the following purpose.
