The invention relates to medicine, where the surgical wound is sutured with different instruments, most often with the use of needle holders, needle and sterile suture material.

Known: the needle holder of Hagara, consisting of two branches with breathtaking needle sponges on the front end, lock and rings for the fingers of the surgeon on the other; needle holder Mathieu with arcuate branches, with spectacular sponges and castle at the end of the handle, rings for fingers has not, therefore, often shifting in his hand, accounts for the surgeon to repeatedly catch during the operation, and the castle often tears the glove in the palm of the hand of the surgeon; the needle holder Troyanova with a curved beak capture for the needles, slightly curved branches, one end of the branches bent towards the other, where the lock is formed. The needle holder Korotkov consists of a straight handle, one end of which is screwed a hollow tube with riffles on the outside and small coils inside. The plate spring is fastened at the top to the mobile industry, at the bottom of the straight handle, right angle bent outwards into the box end mobile branches and snags in the form of a castle, at the edge of the window, holding the needle. Exciting sponge flat with a weak corrugation. During the operation, after the suture, the surgeon gives the needle holder with the needle operating sister, which charges a new Nicko and returns the surgeon and so is repeated many times until the end of surgery [1-4].

The closest is the needle holder [4] with one fixed rod, the end of which is screwed a hollow handle with riffles on the outside and longitudinally spaced small coils in its cavity. The plate spring is mounted above this knob goes up and viceroys on the mobile arched branches; the lower end of the spring is bent at right angles and reaches the window at the bottom of the mobile branches, the edges of which hangs in the castle, holding the needle in the jaws of the front end.

The disadvantages of this needle holder is the presence of flat, slightly fluted surfaces, grab a needle, and therefore the needle unstable, shifting up and down, not allowing the correct puncture tissue. Thin flat spring does not provide a hard grip needle, the spring quickly breaks down near the fixed handle. Cavity screwed the handle is so small that the longitudinal coil can be wound only a thin thread 1-2 seam. The handle is long, thin, holding it impossible to get the lock mobile branches, it is so thin that it is difficult to hold during suture, and the end of the long arm clings to the surrounding tissue, inhibiting operation of the suture.

The aim of the present invention is to reduce the time of suture, maintaining sterile suture material from contamination is saving thread in two or three times.

This goal is achieved by using a device consisting of a long hollow body with a hollow handle on one end and a tip, breathtaking needle, on the other. The handle has a removable lid, fiksiruya front hooks and rear end cap. On the inner surface of the handle laterally - extraction-cells to accommodate the ends of coils with different threads, terminal compartment for spare surgical needles, remains the location for manipulation of the probe. Front handle has a hollow protrusion, on which is placed the base of the hollow body and fixed on the sides. On the upper surface of the hollow body in a special longitudinal bed is handling the plate, starting with the manipulation hook.

Here the ribbed surface of the lock at the bottom of the bed and on the bottom surface of the manipulation of the plate. Ahead of this disc goes into the rod that impaled adaptation spring and eccentric clamping cone. The tip of the cone near the thrust of the rear half of the hollow body. Extended basis eccentric cone and the location of the adaptation of the spring is covered stabilizing clamp. The lateral surface of the eccentric cone convex differently, it marks the degree of convexity, respectively, the numbers of curved surgical needles. N is the end of the front surface of the rear half of the housing has a hollow groove for surgical needles, located at the base resistant, convex anteriorly plate having a center hole to the end of the handling rod. Above the stabilizing clamp apertures through which extend thread, beside them catches of the ends of the threads from the spools located in the handle. The length of the removable housing varies, so depending on the forthcoming operation select case required length. For example, in the abdominal operations needs long-term instruments and, on the contrary, at a superficial wounds are the body of medium size.

After sterilization, open your arms, placed in the cells of the coil of thread of different rooms, their ends manipulation probe conducted through the housing and the holes and pull tabs. Establish a surgical needle at the notch tip and clamp by pressing manipulation of the hook, lockable lock. Close the cavity of the handle end cap. The needle put on the end of the thread needed at the moment diameter. Tweezers grasp the edge of the wound, stitch, pulling manipulation hook up, free needle and perehvatyvat, again clamp and stitch the second edge of the wound. Release the needle and the capture needle tip on the surface of the skin, then pull, thread knotted and cut short. PA is the device again set the needle, clamp and continue to stitch the wound.

Through the use of our proposed device for suturing a wound fails three times to save a sterile suture threads are inside the case and saved from pollution, reducing to a minimum possible complications; eliminate multiple transfer tools (devices) operating sister and back, saving time, reducing the duration of surgery and anesthesia, which in turn has a positive effect on the patient's condition. Due to these advantages this device will find application in surgery, especially in wartime. Changing the length of the body, the device can be used in abdominal operations, such as thoracic, in adults and in children. The presence of three or four spools of thread of different rooms allows you to choose the optimal thread diameter, not referring to your sister. You can install coil with non-absorbable and absorbable in the body threads, as indicated.
