Description
Technical Field
The utility model belongs to the technical field of the anastomat technique and specifically relates to a chamber mirror anastomat nail storehouse subassembly with reset structure.
Background
The disposable intracavity cutting anastomat is a new product and has new innovation on surgical operation; is mainly suitable for the separation, excision and suture of digestive tract tissues such as stomach, intestine, etc. Compared with manual anastomosis, the operation time can be greatly shortened in clinical operation, and the bleeding of a patient can be reduced. Meanwhile, the difficulty of the operation is reduced, the quality of the operation is improved, and the instrument is disposable in order to avoid cross infection in the operation. In order to ensure the safety performance of the disposable intracavity cutting anastomat in the using process and prevent the bleeding phenomenon caused by poor anastomosis performance in the using process, the anastomat needs to perform percussion detection on a nail bin assembly consisting of a wedge, a nail bin, a nail pushing sheet and the like before delivery, and whether the percussion is smooth or not and whether the nail is abnormally formed or not are detected, which is very important, and the result directly influences whether the product after delivery can complete the operation mission or not, so the full inspection is required instead of the sampling inspection. However, the wedge driving member in the existing product is not fixedly connected with the wedge, the wedge driving member cannot be reset with the wedge when reset, and the tail end of the triggered wedge is not provided with the reset inclined plane and the nail pushing sheet inclined plane matched with the reset inclined plane, so the wedge cannot be reset, the nail bin assembly cannot realize the operation function; in another mode, the nail bin is tried to be fired by the same nail bin fixing frame with the damaged positioning buckle, and as a result, the nail bin fixing frame does not realize full detection.
SUMMERY OF THE UTILITY MODEL

The utility model provides a technical scheme that its technical problem adopted is: a nail bin assembly of an endoscope anastomat with a reset structure comprises a nail bin, wherein a nail pushing sheet, an anastomosis nail pushed by the nail pushing sheet and a wedge pushing the nail pushing sheet are arranged in the nail bin; the wedge is provided with a bottom plate, a middle plate and an outer plate are vertically arranged on the bottom plate, the middle plate is positioned in the middle of the bottom plate, the outer plates are positioned on two sides of the middle plate, a reset plate is arranged between the outer plate and the middle plate, pushing inclined planes for pushing the nail pushing sheet to move downwards are arranged at the front ends of the middle plate, the outer plate and the reset plate, a reset inclined plane convenient for the wedge to reset is arranged at the tail end of the reset plate, and the reset inclined plane is an inclined plane of the bottom plate inclining towards the upper left; the front end of the nail pushing sheet is provided with a nail pushing sheet inclined plane matched with the reset inclined plane. The middle plate is clamped into a guide groove in the middle of the nail bin, and the outer plate is clamped into a nail pushing sheet groove for placing a nail pushing sheet. The included angle alpha between the reset inclined plane and the vertical plane is 5-85 degrees, and the included angle beta between the inclined plane of the nail pushing sheet and the vertical plane is 5-85 degrees.
Furthermore, the front end of the nail bin is provided with a through hole convenient for resetting the wedge.
The utility model has the advantages that: the utility model has simple structure, reasonable design and simple and convenient operation, the wedge moves to the left to push the nail pushing sheet to move downwards, when the wedge moves to the left to the work termination position at the leftmost end of the nail bin (namely the wedge pushes all the nail pushing sheets to the work completion position), the reset push rod is inserted into the through hole, the reset push rod pushes the wedge to move to the right until reset, the inclined plane of the nail pushing sheet at the front end of the nail pushing sheet moves downwards along the reset inclined plane until the wedge resets; the slide wedge can reset, improves the utility model discloses a practicality.
