Occur that the slide plate of actuating in another suturing nail driving group is provided with multiple cam wedges, each cam wedge limits multiple angles of bearing, in the time that the first driving angle is greater than the second driving angle, between staple pusher and cam wedge, there is single-point contact, the unstability of staple pusher may cause inclination or the rotation of staple pusher in ejection process, can affect normally identical work of anastomat.
Summary of the invention
The present invention seeks to provides a kind of suturing nail pushing block assembly for above-mentioned weak point, be provided with pushing block, pushing slice of nail, owing to being respectively arranged with concave circular arcs drive surface on the front pushing piece at pushing block, rear pushing piece, on the drive plate of pushing slice of nail, be provided with dome arc drive surface, in the time that anastomat drives, concave circular arcs face matches with convex shaped arc face, can stablize, promote like a cork the suturing nail tissue that coincide.Because pushing block is provided with pushing piece, rear pushing piece above, can be not do not drive pushing slice of nail at one time, can reduce suturing nail and pull the trigger the strength pushing away, make identical tissue manipulation more stable, easily complete anastomosis operation.
Suturing nail pushing block assembly takes following technical scheme to realize:
Suturing nail pushing block assembly comprises pushing block and pushing slice of nail.Pushing block comprises guide plate, front pushing piece and rear pushing piece, and pushing block middle part is provided with guide plate.Be respectively arranged with the front pushing piece in gap, rear pushing piece in guide plate both sides, be provided with groove at pushing block rear portion.
On front pushing piece and rear pushing piece, be respectively arranged with concave circular arcs drive surface.
The concave circular arcs drive surface arc radius R arranging respectively on front pushing piece and rear pushing piece is 12 ~ 120 ㎜.
Pushing slice of nail comprises drive plate and nail pushing plate, pushing slice of nail is at least provided with a nail pushing plate, and pushing slice of nail bottom is provided with drive plate, and drive plate is connected with nail pushing plate, drive plate is provided with dome arc drive surface, and the dome arc drive surface of drive plate setting matches with the concave circular arcs drive surface of pushing block.
The dome arc drive surface arc radius R2 of drive plate setting is 12 ~ 120 ㎜.
Be respectively arranged with pushing slice of nail positioning boss in the forward and backward side of nail pushing plate, at nail groove, location be installed for pushing slice of nail.
Be provided with suturing nail locating slot on nail pushing plate top, locate for suturing nail.
Described nail pushing plate is not contour nail pushing plate or contour nail pushing plate.
When suturing nail pushing block assembly uses, first pushing slice of nail is contained in to the nail trench bottom of nail bin, pushing block is contained in to nail bin rear portion, nail bin is arranged in nail bin seat, be fixed in nail bin seat groove by nail bin locating fastener location, again not contour suturing nail is arranged in corresponding nail groove, forms nail bin groupware, coincide and support the use for surgical operation.
Suturing nail pushing block component design is reasonable, compact conformation, owing to being respectively arranged with concave circular arcs drive surface on the front pushing piece at pushing block, rear pushing piece, on the drive plate of pushing slice of nail, be provided with dome arc drive surface, in the time that anastomat drives, concave circular arcs face matches with convex shaped arc face, can stablize, promote like a cork the suturing nail tissue that coincide.Because pushing block is provided with pushing piece, rear pushing piece above, can be not do not drive pushing slice of nail at one time, percussion suturing nail, can reduce suturing nail and pull the trigger the strength pushing away, make identical tissue manipulation more stable, easily complete anastomosis operation.
Suturing nail pushing block assembly of the present invention, for the suturing nail pushing block assembly of surgical operation suturing device, is specially adapted to intracavity anastomat and supports the use.
