Description

Technical Field

[0001] The utility model relates to a fixture for a sleeve assembly of a stapler cartridge. Background Art

[0002] In the laparoscopic linear electric cutting stapler, a stapler steering sleeve and an anvil are usually provided. The stapler steering sleeve has a lumen, the side of the lumen passes through the stapler steering sleeve and an opening is formed on the stapler steering sleeve, a tongue is provided in the opening, and the anvil has a convex block. When manufacturing the stapler cartridge stapler sleeve assembly, the convex block of the anvil needs to be installed in the opening of the stapler steering sleeve, and the tongue in a flat state is pressed into an inclined state by stamping, so that the convex block and the tongue can restrain each other to complete the assembly of the stapler steering sleeve and the anvil. However, the existing press machine does not have a jig dedicated to the stapler cartridge stapler sleeve assembly, resulting in low stamping accuracy, so a stapler cartridge stapler sleeve assembly jig is needed.

In the closed state, the upper die can punch the tongue on the stapler turning sleeve so that the tongue on the stapler turning sleeve and the protrusion on the anvil seat can be restrained from each other.

[0006] The limiting member is used to limit the horizontal movement of the stapler steering sleeve in the fixing groove so that the tongue on the stapler steering sleeve can correspond to the position of the protrusion on the anvil seat.

[0007] The stapler cartridge stapler sleeve assembly jig of the utility model can limit the stapler steering sleeve horizontally placed on the fixing groove of the lower die by setting a limiter, effectively preventing the stapler steering sleeve from moving in the horizontal direction during the stamping process, thereby ensuring that when the die is closed, the tongue on the stapler steering sleeve can correspond to the position of the protrusion on the stapler seat, so that the upper die can accurately stamp the tongue on the stapler steering sleeve so that the tongue on the stapler steering sleeve and the protrusion on the stapler seat can restrain each other.

[0008] In some embodiments, the limiting member has a limiting groove, which is coaxially arranged with the fixing groove and can cooperate with the fixing groove to maintain the horizontal position of the stapler steering sleeve.

[0009] In some embodiments, the limiting member has a limiting top surface and a limiting bottom surface, and the limiting groove is formed by the limiting top surface being recessed toward the limiting bottom surface.

[0010] In some embodiments, the limiting member includes a connecting portion and a limiting portion, wherein the limiting portion is fixed to the connecting portion and only partially covers the surface of the connecting portion, and the limiting portion is used to limit the horizontal movement of the stapler steering sleeve in the fixing groove.

[0011] In some embodiments, the lower mold has a mold top surface and a mold bottom surface, and the fixing groove is formed by the mold top surface being recessed toward the mold bottom surface.

[0012] In some embodiments, the fixing groove is covered with an anti-slip layer.

[0013] In some embodiments, a bottom plate is further included, and the lower mold and the limiting member are detachably mounted on the bottom plate.

[0014] In some embodiments, a mounting groove for placing the lower mold and the limiting member is formed on the bottom plate.

[0015] In some embodiments, a connecting member is further included, and the connecting member is used to lock the lower mold and the limiting member on the bottom plate.

[0016] In some embodiments, a mounting piece is further included, and a movable mounting hole is opened on the base plate. The mounting piece is used to pass through the movable mounting hole and can adjust its horizontal position in the movable mounting hole to adjust the installation position of the base plate.
