Description

with a tipping bar 10 with a bevel And, moreover, the bevels 7 and 11 are located on the same line, and the platform 8 coincides with the working surface 12 of the bracket housing 1. On the inner walls of the housing 1 are made guides 13 and 14 for moving the bars 6 and 10, and the guides 14 have an inclined section 15 located at the working end behind the staple slots 9. Moreover, pin 16 is fitted with a pin 16 and a groove 17 is selected, slot 18 and an emphasis 19 are made on bar 6, body 1 and body 4 are connected by a shaft, p «20.

The device works as follows.

The fabric to be sutured is positioned in the piercing zone (see FIG. 1) and compressed between the matrix 5 and the working surface 12 of the bracket body 1.

The closure of the staple and stop bodies 1 and 4 is accomplished using a locking mechanism. Additional bar 10 for the handle 21 is pushed along the T-shaped groove 9 in the cTOipo "y of the bracket 22. The bevel 11 of the bar 10 engages with the bracket 22, squeezing the fabric. The position of the bevel And slat 10 relative to the clevis 22 defines the clearance gap. In order to avoid spontaneous opening of the apparatus during the flashing, the bevel angle 11 is selected less than the self-locking angle.

Putting the index finger on the stop 23, and the big one on the handle 24 of the pushing bar 6, push the latter along the bracket housing 1 towards the bracket 22. The bevel 25 of the removable part 26 acts on the bracket 3, pushing it along the bracket grooves 2 towards the matrix 5. How only the bevel 25 of the removable part 26 passes the bracket, it is immediately affected by the bevel 7 of the pushing bar 6, which is a continuation of the bevel 25. Since the horizontal platform 8 of the pushing bar 6 coincides with the working surface 12 (see FIG. 3) of the bracket body 1 push bar 6 floor completely pushes the bracket 3 (see FIG. 1) out of the bracket grooves 2.

Bracket 3, the fabric punctured with its feet, abuts against the well of the matrix 5, bends in a B-shape, firmly connected to the sewn fabric.

Since the removable piece 26 and the push bar 6 with its bevels 25 and 7 directly act on the bracket 3, the push bar as an intermediate piece becomes unnecessary. The height of the cross section of the bracket body 1 is folded in the known apparatus from the height of the bracket and the height of the pusher. Due to the fact that in this apparatus there is no pusher, the height of the cross section of the bracket body 1 will depend only on the height of the bracket and will be less than the height of the cross section of the bracket body of any similar device to the height of the pusher.

As soon as the removable piece 26 passes the weld zone, its longitudinal protrusions 27 fall into the inclined section 15 of the guides 14 (Fig. 3), the passage along which the removable piece 26 rises above the pushing bar 6.

In this case, the pin 16 of the removable part 26 is disengaged from the nest 18 of the pushing bar 6. As soon as the puff comes out of the engagement, the removable part 26 no longer connects 5 to the pushing bar 6 and it stops further, Continuing to lower the brackets that have not been pushed out to the end.

Thanks to this design, the pushing bar can be telescopically folded, with the result that the working end of the device, located behind the seam area and designed to accommodate bevels 25 and 7 of the pushing bar 6, can be made shorter. If the plate has one removable part, then the non-working end of the device can be made two times shorter, if two parts are eaten, three times shorter, and so on.

The shorter non-working end of apparatus 0 facilitates the approach to the operated organ.

When the pushing bar 6 is retracted to its initial position, its protrusion 19 rests on the edge of the groove 17, and carries it along.

The removable part, having passed the inclined section 5 15, passes to the horizontal section 28, moving closer to the pushing bar 6. The pin 16 enters the socket 18 and the pushing bar 6 with the removable part 26 in this position is one whole piece with a total 0 bevel.

The device is opened by abduction of the strap 10 and removed from the stitched fabric.

Reducing the size of the device entails a reduction in the operative wound, necessary for the approach, to the operated organ, which in turn shortens the postoperative period.
