Abstract
The utility model provides a needle supporting seat for an anorectal anastomosing device. The needle supporting seat comprises a seat body, wherein a plurality of nail slots are arranged in an upper ring surface of the seat body, the side walls of the two sides of each nail slot are inclined inwards from top to bottom, and the widths of the bottoms of the nail slots are increased from the middle part to the two sides in the length direction.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of anorectal anastomat with supporting needle stand.
Background technology
Endless knife is armarium commonly used in the modern medical service process, and it excises incidence tissue by endless knife.After incidence tissue is cut, follow closely wound suture with titanium, when wound is sewed up, realize the stitching of titanium nail by supporting needle stand, but in the prior art, the nail groove that supports in the booking all is regular geometric shape, generally all be rectangular, the width of this structure nail groove is greater than the diameter of titanium nail, and the titanium nail can shake in the nail groove when bending, titanium nail molding meeting generation deviation causes the sewing effect of wound bad after sewing up.
Summary of the invention
For solving above-mentioned technical problem, this utility model provides a kind of anorectal anastomat of wound suture that is conducive to supporting needle stand.
The technical solution of the utility model is, provide a kind of anorectal anastomat with following structure with supporting needle stand, it comprises pedestal, and the upper ring surface of pedestal is provided with several nail grooves, the sidewall of nail groove both sides slopes inwardly from top to bottom, and the width of nail trench bottom is expanded to both sides along its length from the centre.
After adopting said structure, the utlity model has following advantage:
Original common rectangular staple groove is done suitable improvement, make the contraction that slopes inwardly of the sidewall of its both sides, titanium when so both being conducive to sew up nail can dock with the nail groove out the time smoothly from nail bin, be conducive to again in the bending of titanium nail, sidewall can play guiding function, can accurately align after making the two ends bending of titanium nail, effectively avoid the molding deviation, be conducive to the rear stitching to wound of anastomat cutting.
Better, the nail groove on the upper ring surface is arranged in inside and outside two circles, and the nail groove cross-distribution on the Internal and external cycle.This structure is conducive to improve the sewing effect of wound.
Better, the spacing between the nail groove on the upper ring surface inner ring and the internal diameter of upper ring surface is: a=0.3mm～1mm.Can guarantee like this that after the upper ring surface of needle stand is being established nailed groove especially inboard can have enough power resistance strengths, like this, the reliability of supporting needle stand in the time of can guaranteeing to be the nail bin cooperation improves the sewing effect to wound.
Description of drawings:
Fig. 1 is this utility model anorectal anastomat structural representation that supports needle stand;
Fig. 2 is this utility model anorectal anastomat front view that supports needle stand.
The specific embodiment:
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
As shown in Figure 1 and Figure 2, this utility model anorectal anastomat is with supporting needle stand, and it comprises pedestal 1, and the upper ring surface 1.1 of pedestal 1 is provided with several nail grooves 2.The sidewall 2.1 of nail groove 2 both sides slopes inwardly from top to bottom, and the width of nail groove 2 bottoms is expanded to both sides along its length from the centre.Like this, nail groove 2 just just forms the little shape in large centre, two ends in shape, two ends are large, the titanium nail that is conducive in the nail bin can dock with nail groove 2 smoothly, and after the titanium nail enters nail groove 2, under the guiding of sidewall 2.1, can locate Dock With Precision Position in the centre position of nail groove 2 smoothly, more satisfactory to the sewing effect of wound.
For reaching better sewing effect, the nail groove 2 on upper ring surface 1.1 is arranged in inside and outside two circles, and nail groove 2 cross-distribution on the Internal and external cycle.
Be to guarantee the intensity of upper ring surface 1.1, guarantee has certain spacing between the internal diameter of nail groove 2 on upper ring surface 1.1 inner rings and upper ring surface 1.1, and spacing is preferably: a=0.3mm～1mm is preferably 0.5mm in this example.
