Abstract

FIELD: medical engineering.

SUBSTANCE: device has handle having reel inside and casing having end for capturing needle. The handle has transverse reels and is connected to the hollow casing. Longitudinal bed bearing manipulation plate having lock and manipulation hook. The manipulation plate becomes a rod in its frontal part. Adaptation spring and eccentric pressed cone are put-on over the rod. The cone serves for fixing needle and reaches casing rest member.

Description

The invention relates to medicine, where in surgery, wounds are sutured with various instruments, most often using needle holders, needles and sterile suture material.

Known: Geghar needle holder, consisting of two jaws with sponges capturing the needle - at the front end, a lock and rings for the surgeon's fingers - on the other; the needle holder Mathieu with arched jaws, with gripping lips and a lock at the end of the handle does not have finger rings, therefore it often moves in the hand, the surgeon has to repeatedly intercept during the operation, and the lock often tears the glove in the surgeon’s palm; Troyanov’s needle holder with a curved beak-like grip for needles, weakly curved branches, one end of the branch bends towards the other, where a lock forms. The Korotkov needle holder consists of a straight handle, to the end of which a hollow tube with corrugations on the outside and small coils inside is screwed. The leaf spring is attached at the top to the mobile jaw, at the bottom of the straight handle, bends outward at a right angle, penetrates the window of the end of the mobile jaw and clings in the form of a lock to the edge of the window, clamping the needle. Gripping sponges are flat with a slight corrugation. During the operation, after suturing, the surgeon gives the needle holder with the needle to the operating nurse, who charges it with a new thread and returns it to the surgeon and is repeated many times until the end of the operation [1-4].

The closest is the needle holder [4] with one fixed rod, to the end of which a hollow handle with corrugations outside and longitudinally located small coils in its cavity is screwed. A leaf spring is attached above this handle, goes up and is fixed on a mobile arc-shaped jaw; the lower end of the spring bends at a right angle and reaches the window at the bottom of the mobile jaw, which clings to the edges in the form of a lock, clamping the needle in the lips of the front end.

The disadvantages of this needle holder are the presence of flat, slightly grooved surfaces that capture the needle, and therefore the needle is unstable, moves up and down, preventing proper puncture of the tissues. A thin flat spring does not provide a firm grip on the needle; the spring breaks quickly near the stationary handle. The cavity of the screwed handle is so small that only a thin thread for 1-2 seams can be wound on the longitudinal reel. The handle is long, thin, holding it is impossible to get the lock of the mobile jaw, it is so thin that it is difficult to hold it during suturing, and the end of the long handle clings to the surrounding tissue, delaying the suturing operation.

The aim of the present invention is to reduce the time of suturing, maintaining a sterile suture material from contamination and saving threads by two to three times.

This goal is achieved using a device consisting of a long hollow body with a hollow handle at one end and a tip that captures the needle on the other. The handle has a removable cover, which is fixed on the front by hooks and on the back by an end cap. On the inner surface of the handle from the sides there are recesses-cells for accommodating the ends of coils with different threads, the end compartment for spare surgical needles, there is still room for the placement of the manipulation probe. In front, the handle has a hollow protrusion on which the base of the hollow body is mounted and fixed laterally. On the upper surface of the hollow body in a special longitudinal bed is a manipulation plate starting with a manipulation hook.

Here is the ribbed surface of the castle at the bottom of the bed and on the bottom surface of the manipulation plate. In front, this plate passes into the rod, on which the adaptation spring and the eccentric clamping cone are mounted. The top of the cone near the thrust part of the rear half of the hollow body. The expanded base of the eccentric cone and the location of the adaptation spring are covered by a stabilizing collar. The lateral surfaces of the eccentric cone are convex in different ways, there are marks on the degree of convexity according to the numbers of curved surgical needles. At the end of the front surface of the rear half of the body there is a recess-groove for surgical needles located at the base of a persistent, convex anterior plate, with a hole in the center for the end of the manipulation rod. Above the stabilizing collar, the holes through which the threads exit, next to them are the ends of the threads from the spools located in the handle. The length of the removable housing varies, so depending on the upcoming operation, choose the housing of the required length. For example, for abdominal operations, long instruments are needed and, conversely, for shallow wounds, medium-sized cases are used.

The device operates as follows. After sterilization, the handle cover is opened, the spools with threads of different numbers are placed in the cells of the spool, their ends are held by a handling probe through the housing and holes and hooked to the latches. Set the surgical needle in the recess of the tip and clamp by pressing the manipulation hook, which is fixed by a lock. Close the cavity of the handle with an end cap. On the needle put on the end of the thread of the currently required diameter. With tweezers, they grab the edge of the wound, stitch it, pull the manipulation hook up, release the needle and intercept it, again clamp and stitch the second edge of the wound. Release the needle and grab the end of the needle on the surface of the skin, then pull it out, knit the threads and cut it short. A needle is reinserted into the groove of the device, it is clamped and sutures continue to be placed on the wound.

Thanks to the use of the device for suturing the wound that we have proposed, sterile suture material can be saved up to three times, the threads are inside the case and are preserved from pollution, minimizing possible complications; multiple transfer of the instrument (device) to the operating sister and vice versa is excluded, saving on this time, reducing the duration of the operation 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 wartime. By 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 with different numbers allows you to choose the thread of the optimal diameter without resorting to the operating sister. You can install coils with non-absorbable and absorbable threads in the body, as indicated.
