Description

Technical Field

[0001] The utility model relates to the technical field of staplers, in particular to a stapler cartridge seat capable of preventing rivets from falling off. Background Art

[0002] A stapler is a device used in medicine to replace manual suturing. Its main working principle is to use titanium staples and a cutting knife to staple and separate tissues. The stapler's staple principle is similar to that of a stapler, while the stapler's cutting works by using a cutting knife hidden in the sleeve to cut tissues while stapleing them. The cutting knife cuts as the push rod pushes it and moves in the middle groove between the staple magazine and the staple holder.

[0003] In the prior art, the anastomosis device's nail support and nail magazine seat are connected by rivets. Since the anastomosis device and the nail magazine seat need to rotate continuously and both have the requirement of relative opening and closing, the rivets at the riveted joint between the two are likely to loosen. The loose rivets may fall into the patient's body and cause a surgical accident.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a rivet-proof rivet magazine seat is proposed. Utility Model Content

[0005] The utility model aims to provide a rivet-proof nail magazine seat to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a nail magazine seat for preventing rivets from falling off, comprising a hollow rod and a connecting pin, the end of the hollow rod is rotatably connected to a rotating pin, and the ends of the connecting pieces on both sides of the rotating pin are penetrated with a through hole one, the connecting pin is correspondingly arranged on the outside of the rotating pin, and the nail magazine seat is connected to the rotating pin for pitch rotation through the connecting pin, and the ends of the connecting pieces on both sides of the connecting pin are penetrated with a through hole two.

[0007] Furthermore, an inner clasp is provided inside the opposite surface of the rotating pin and the connecting pin, and the inner clasp is a strip-shaped metal structure.

[0008] Furthermore, a connecting rod is fixedly connected to the bottom left side of the inner panel, and a ball boss is integrally fixed to the end of the connecting rod.

[0009] Furthermore, a sleeve is fixedly installed on the right bottom of the inner piece, and a slot is provided in the inner cavity of the sleeve.

[0010] Furthermore, an outer buckle sheet is provided on the outside of the opposite surface of the rotating pin and the connecting pin, and an insertion rod is fixedly connected to the top of the right side of the outer buckle sheet, and the insertion rod is plugged into and matched with the sleeve through a slot.

[0011] Furthermore, a female buckle is fixedly installed on the top left side of the outer buckle piece, and the internal hole groove of the female buckle matches the ball protrusion.

[0012] Furthermore, an elastic clamping roller is provided on the inner wall of the female buckle opening, and the elastic clamping roller is made of spring steel and has deformation capability.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The utility model avoids the risk of falling in the traditional technology of using rivet connection by using the inner lap piece and the outer clasp piece. When in use, the inner lap piece is inserted into the hole groove of the left female buckle of the outer clasp piece through the ball protrusion at the end of the left connecting rod, and the deformation of the elastic clamping roller prevents the ball protrusion from separating and falling off in the hole groove. Secondly, the inner lap piece is inserted into the slot of the right sleeve of the outer clasp piece through the right insertion rod, so as to realize the connection between the connecting pin and the rotating pin, and meet the use requirements of the relative opening and closing of the nail support seat and the nail magazine seat.

[0015] 2. When the utility model is in use, the use of the inner plate and the outer buckle plate can not only meet the rotation and relative opening and closing requirements of the nail support seat and the nail magazine seat, but also the inner wall of the inner plate is smooth to avoid interference with the reciprocating pulling stroke of the core piece in the hollow rod, thereby ensuring the accuracy of the use of the anastomosis device.
