Pin abutting seat for surgical staple

Abstract

The invention provides a pin abutting seat for a surgical staple. The pin abutting seat comprises a seat body, wherein a head portion of the seat body is connected with a cover of the pin abutting seat in the surgical staple, one end, opposite to the cover of the pin abutting seat, of the seat body is provided with a plurality of screw slots, each two screw slots forms one group, and the two screw slots in one group are symmetrical. The pin abutting seat is characterized in that each screw slot is in an isosceles trapezoid shape, short straight sides of the screw slots in each group are close, two side walls in the inclined side directions of the screw slots are inclined towards to bottoms in the slots along the straight side directions, and the side walls, from the inclined side direction to two straight side directions, of the bottoms of the screw slots are expanded to form arc surfaces. Forming surfaces of the screw slots are designed into specific arc shapes, so that the screw slots have a direction self-guidance property; during a percussion titanium screw forming process, the phenomenon that a B shape produced by irregular motion of screw clamps in the screw slots is not in the same plane is avoided, and good seaming effects of operations are achieved.

Description

technical field [0001] The invention relates to a medical device, in particular to an abutment seat applied to a surgical intestinal end-to-end stapler. Background technique [0002] The working principle of the anastomotic (suture) stapler is the same as that of the stapler, that is, two rows of interlaced staples are fired into the tissue to perform two rows of intersecting staples, and the suturing is tight to prevent leakage; The "B"-shaped staples pass through the gap, so the blood supply of the sutured part and its distal end will not be affected. All staples are made of titanium or tantalum, which is less tissue reactive than manual sutures. [0003] The suturing of the wound with titanium nails is achieved through the abutment seat, but in the prior art, the nail grooves on the nail abutment are all regular geometric shapes, generally rectangular, and the width of the nail grooves in this structure is larger than that of titanium nails. The diameter of the nail, th...

[0003] The suturing of the wound with titanium nails is achieved through the abutment seat, but in the prior art, the nail grooves on the nail abutment are all regular geometric shapes, generally rectangular, and the width of the nail grooves in this structure is larger than that of titanium nails. The diameter of the nail, the titanium nail will shake in the nail groove when it is bent, and the titanium nail cannot be formed in the same plane, resulting in poor strength after the titanium nail is formed, and the sutured tissue will ooze and even the wound will crack during the recovery period
