SU121532A1 - Apparatus for crosslinking nerves with metal brackets - Google Patents

Description

The subject of the invention is an arrangement for fastening the epineuria along the edges of the ends of the incised nerve with U-shaped brackets (clips) that form an intermittent circular seam, without affecting the area of the nerve fibers.

Apparatuses are known for cross-linking blood vessels with metal brackets, which are placed in a magazine box and which are folded in the wells of the matrices by a pusher, which are driven manually by the control levers.

The proposed apparatus for crosslinking nerves mechanically collects peotpreparirovanny epineurium of the rollers at the edges of sections na both ends nerve vystunami stores and matrices half sleeves at opposite their convergence, fixes comparison nerve Koptsov coupling halves half sleeves and Cpd a razobsh; ennye ends nerve momentary overlay epipevralpogo weld metal. tical brackets, calcining epineural rollers with bend legs (brackets) on the matrix. In addition, the machine sews the first various sizes. It is equipped with interchangeable semi-sleeves of various sizes: "bracket with magazines for brackets and" stop-with matrices for bending. To hold the ends of the stitched nerve on the apparate's anvil, the cores of the first apollo are attached, shaped like sponges with gate valves to close them.

FIG. 1 image of the apparatus assembly, the overall appearance; in fig. 2 is the same, top view, in FIG. 3 - the disposition of replaceable half bushings; pas figs. 4 shows in two projections of bracket half-sleeves of various types; in fig. 5- types of stop bushings; in fig. b- left nerve holder is shown in two projections; in fig. 7 - right first holder.

The device is composit pz left (phg. 1) and herva (fig. 2) converging floors P1 (branch).

Each half of the apparatus consists of the following parts of the same name: the hull of the Y, the ylanka 2, and the gate valve 3. In addition, the left and half levers 4 are located, and on the right - the gate-regulator 5.

Replaceable half-sleeves 6 and 7 are inserted into the jaws of the apparatus for cross-linking nerves, and holders 8 and 9 of the nerves are attached to the body.

According to funkio1 L.1Y1YM nri: nakam half sleeve are divided into "bracket" (Fig. 4)) i "unorpy (FPG. 5).

The bracket semi-sleeves are equipped with shops into which brackets are inserted, and the supporting half-sleeves are equipped with matrices with the legs of the brackets folded over at the interlock.

Shops n in the form of suits in semi-tubular cases, exchange 1, and epa symmetrically; their number depends on the size of the half bushes.

The bracket half bushes consist of three detachable parts: housings 10 with inserts 11 for supporting the pushers and coupling halves with magazines in which brackets are placed; pushers 12 for pushing the staples out of the magazines 13, semi-couplings 14, covering the stitched ends of the nerve and fixedly fixing them in the mapped position. The bracelets of the tillers are fixed with brackets and irosed with tweezers.

The thrust half-sleeves consist of two detachable parts: bodies 15 with dies, in the holes of which the legs of the brackets with inserts / 6 for supporting the gyumumuffs are bent, and for the coupling half 17, covering the stitched ends of the nerve and fixed them in a fixed position.

The nerve holders hold the ends of nerves in the half sleeves of the apparatus and fix the half couplings of the half sleeves in the position required for stitching.

According to their placement on the corresponding bodies of the halves of the apparatus, the nerve holders are divided into the left fig. 6) and right (Fig. 7). Kaledy turf consists of two detachable parts: tweezers and valves. The tweezers are made in the form of two jaws 18 and 19 with serrated bars at the ends to hold the nerve: the upper sponge is spring-loaded, the lower is sponge BPDf, the lock 20 and tab 2 / for fastening are provided.

The device operates as follows.

The apparatus halves, in which the jaws are inserted into half-sleeves, matched to the size of the nerve (of which the brackets are charged with brackets), in a disconnected form, with strips removed, with the holders jaws open and with the couplings of all the half-sleeves installed in the initial position (i.e. inserted into the crown of the novoltulok up to the stop), put under the ends of the first.

The ends of the stitched nerve are placed on the lower jaws of the holders and into the half-couplings of the half-sleeves inserted into the annarat shells, with the edges of the slices in the level with the ends of the half-couplings without preparing the epineuria, the same for the left and right halves of the apparatus. After that, the upper jaws of the holders lower the nerves and fix the backward scam. Then, the rams of the apparatus with the upper half-sleeves are placed on the hulls of the apparatus and locked on them with valves, so that the coupled coupling halves are interlocked.

At the end of the preparatory part of the operation, both halves of the apparatus with the ends of the nerve are brought to the necessary gap (of the scale of the apparatus) and locked.

At the approach of the halves of the annarat of the half-coupling of the "bracket and" stop semi-bushings, the ends face one another, fixing

in the unconnected epolus of the epia, juxtaposed nerve ends. Together with the device nolovinka, the cases along; the first sleeves, the stores and the matrices, with their lines passing into the grooves of the coupling halves and slightly immersed in the epineurium in a counter-axial movement, assemble in front of them the epineural valncs to the line of the ends of the heel. The nerve holders, along with the apparatus halves, also meet each other and, in the final working position, the side planes of the jaws attach to the flanges of the coupling halves, holding them in an undifferentiated nanozhenni.

When pressing the fingers on the levers, the followers of the followers rotate and move the pushers in axial direction to the seam line, the pushers pull the brackets out of the stores. The brackets, the punctures, the chipper rollers and without affecting the nerve fiber zone, abut the legs into the wells of the matrices, the resistant half-shells and there they are bent. An eyeplot is attached along the nerve circumference simultaneously.

The release of the nerve from the plugs and nerve dermis of the nerve occurs as follows. First, the shutter-regulator is pushed back until it is folded, in which the halves of the annarate remain locked. In this case, the apparatus halves, together with the shells of the half-sleeves and the derl: the cranes of the first, are somewhat separated, the valves of the apparatus are pushed back, and the strips with the upper half-sleeves are removed. Then the backs of the holders are pushed back, their sponges are unlocked, as a result of which the upper bars of the holders of the holders are raised and the stitched nerve is removed from the lower half-shells, and the apparatus together with the nerve holders are removed.

Subject invention

1, A device for the sprouting of nerves with metal brackets pledged into a magazine box and folded in the wells of the matrices under the influence of a pusher applied in the case of a manual pa control levers, characterized in that, in order to simultaneously disconnect the epineural H1A, it is separated from the wiring on the wedge of the wiring. assembled in the form of rollers at the ends of the cut projections of magazpov and matrices with a counter-nx approach, detachable sponges on both branches of the apparatus provided him with plug-in interchangeable semi-sleeves with sleeve couplings d uo fixing various sizes nerves staple shops for brackets and the abutment with the matrices for their folded.

2. Annara no. 1, which is distinguished by the use of fixed anchors on the jaws of the holders of the ends of the stitched nerve, formed into the form of jagged sponges with back twigs for their closure.
