Description

The invention relates to medical technology, namely to surgical instruments, and can be used for sewing soft tissues with metal staples.

A device for applying stapled seams is known, which contains pivotally connected branches, one of which has a supply mechanism for stapling the wire and another for a matrix with a shank for bending the sideways, a driver of the brackets and an ejector of the brackets 1.

A disadvantage of the known device is the length of time of cross-linking of soft tissues due to the necessity of impaling them with the gumos tweezers on the staple wire projecting in the working area.

The purpose of the invention is to reduce the time of stitching fabrics.

The goal is achieved by the fact that in a soft tissue stitcher containing pivotally connected branches, one of which has a mechanism for supplying a brace forming wire, and on the other, a matrix with a shank for bending the brackets, a brace former and a brace ejector, the brace former is equipped with a knife , and one of the branches has a protrusion and is kinematically connected with the matrix and the ejector, which are made movable, and the shank of the matrix interacts with the projection of the branch.

FIG. 1 shows a soft tissue stapler, a general view; in fig. 2 is a view A of FIG. one; in fig. 3 is a section BB in FIG. one.

The soft tissue spindle contains pivotally connected upper 1 and lower 2 branches, on one of which (lower 2) there is a feed mechanism for a staple-forming wire, made in the form of a lever 3 with a groove 4, set to 1, its movement, and on the other (upper 1) - the matrix 5 with the shank 6, the driver 7 brackets, the ejector 8 brackets, the knife 9 and the protrusion 10.

In the front part of the lower branch there is a through drip 11 for a staple-forming wire. The feed lever 3, at its end, on which there is a notch 12, presses the wire to the support platform of the lower branch 2, which passes into the channel 11. The spring 13 presses the feed lever 3. In the front part of the branch 1 there is a gear 10, which interacts with the ejector 8 brackets movably mounted on the staple lever 14, which holds the spring 15 in the initial position. The brace lever 14 ends with the brace former 7, provided with a knife 9 that cuts the calibrated pieces of wire. The clamp arm 14 is kinematically connected to the top jaw 1, lifting when open.

tii and lowering when closing branches. The matrix 5 is made with a groove 16, which is a continuation of the channel 11, is mounted movably on the axis 17 and interacts with its shank 6 with a hole in the projection 18 placed on the side of the bia brane 1.e. The former 7 of the brackets has a groove 19 in its front part that provides accurate installation of the wire, and inside - a longitudinal groove 20, in which the U-clip is fixed in the longitudinal direction. The matrix part of the upper jaw is also equipped with a slider regulator 21 of the closure size and has matrix grooves 22 for bending the brackets, as well as a roller 23, which is installed in the groove 4 of the wire feed lever 3.

The stapler works as follows.

When the upper 1 and lower 2 branches approach at the time of passing po; 1ika 23 along the straight section of groove 4, the feed lever 3 moves forward and, pressing the staple wire with the free end with notch 12 to the supporting surface of the pnya 6paiiuiii 2, delivers a calibrated piece of wire along channel 11 to the stapler zone. Eio, the travel time of the p.pike 23 along the radially curved section of the groove 4 and the feed lever 3 remains in place. At the time, the knife 9 cuts off the calibrated piece of wire, and the shaper 7 brackets, pressing on the free ends of the wire, stand out, on both sides of the movable matrix 5, forms the P-on}) bracket, which is installed in the longitudinal grooves 20. Subsequently The clamp 1P1P brapp movable matrix 5, interconnecting its shank 6 with the protrusion 18 of the upper jaw 1, moves away in turn and releases the finished bracket from the groove 16. With the final approaching the brace the protrusion 10 presses the ejector 8, which pushes the bracket from the grooves 20 until the fabric is stitched, abutting into the matrix pits: 1С1П1 22 and forming the B-bracket, which is attached.

When opening a bridge, all movements of the binder mechanism occur in the reverse sequence, with the ejector 8 brackets rising under the spring 15. When the return shaft, the wire feed lever 3, end ci-o with notch 12, moves away from the supporting surface, which warns reverse t giv wire.
