The invention relates to medical equipment, namely to surgery.

The aim of the invention is to reduce the morbidity and reducing the time of suture.

When suturing laparotomy wounds remains a small section of 2-3 cm, almost inaccessible to visual inspection. When applying ligatures to the aponeurosis of the risk of injury by the needle, podszywania be organs (bowel, celeration complications such as postoperative ventral hernia, intestinal obstruction, dictates the need for surgeons to seek ways to tackle this important issue in the creation of new methods and instruments for suturing wounds after surgery.

As a prototype, the authors propose a device for applying ligatures (Ed. certificate # 167006 from 12.12.64, BI No. 24, 11.12.64). The device comprises a pivotally connected intersecting branches with rings for fingers on one side and ending in a curved working sponge on the other. Touching the ends of the working jaws made in the form of aligned hooks, bent to the side rings for fingers, the gnashing of forming a window and a slot for holding the ligature.

Some drawbacks are the limited scope (for applying ligatures on renal stem), the inability to suturing of other organs and tissues, insecurity due to lack of locking cremallera.

The authors propose a device for applying ligatures (drawing) containing overlapping branches 1 and 2, connected by a hinge 3, on the one hand with rings for fingers 4 and cremalleras 5, the locking position of the branch. On the other hand, the branches made mi jaws 8.

Working sponge 8 is made in the shape of the shoulder (width 15 mm, length 25 mm), bent at a right angle with the bend radius of 2 mm Along the length of the working surface of the sponge is deepening in the form of grooves 10 a width of 11 mm and a depth of 3 mm, an Outer surface of the sponge has a smooth streamlined shape. The gnashing of both workers sponge 8 together with the branches is executed in the form of two parallel metal rods 6 and 7, form a pass-through window 9 for holding the needle with a ligature.

The proposed device operates as follows: immersed in laparotomy wound and set through the window 9 is perpendicular to the plane of curvature of the surgical needle. Working jaws 8 are closed up. When diving they carefully push back underlying organs (loops of intestine and omentum) down and to the sides of the abdomen.

Securely stitched to one edge of the aponeurosis, surgical needle with a ligature is in box 9 without visual control needle stitched the opposite edge of the aponeurosis, the needle is shown, along with a ligature. From a wound in the decompressed state is removed the clip and the ends of the ligature tie.

The advantages of the proposed device is reducing the trauma of the atomic wounds of any location with limited visual inspection (after minilaparotomy, after videolaparoscopic interventions).

SUBSTANCE: method involves mounting implant on supporting platform. The platform is turned and moved about and along its longitudinal axis to enable one to arrange needle in any given position on implant surface. The needle is controllable in a way that the first thread is brought through the implant wall from the first side of the wall. The first loop is formed from the first loop on the second implant wall. The thread is brought through the loop. The loop is tightened to produce a stitch. The stage the thread is passed through the loop is carried out by means of device movable back and forth along longitudinal implant axis. The device additionally has at least one driving mechanism for turning and moving transplant platform about and along its longitudinal axis to enable one to arrange needle in any given position on implant surface and additional driving mechanism for passing thread through the loop back and forth along longitudinal implant axis. Main device head piece is movable into any required position as a result of implant-carrying cylinder rotation or axial displacement on implant surface.

EFFECT: wide range of functional applications; enabled fitting of anatomical tubes of different diameters in several points arranged on an axis.

SUBSTANCE: one should perform marginal serous-muscular-submucous suturing for every wall of intestinal wound in oblique direction against cross-sectional intestinal axis being parallel to lateral branches of intraparietal intestinal vessels at an angle being opened towards mesenteric edge. Puncturing in and puncturing out of stitches at the serous membrane of every further suture should be performed being on the same line with puncturing in and puncturing out of stitches at the border of submucous and mucous layers of previous suture. Sutures should be tightened at forming the knots at serous membrane. The innovation suggested enables to decrease the frequency in developing failed sutures.

SUBSTANCE: method involves implanting a ribbon into the body on each side of the urethra between the vaginal wall and abdominal wall. The ribbon is drawn above the pubic bone. The ribbon is introduced on both sides of the urethra to make a loop around the urethra. It is arranged on each side of the urethra between the vaginal wall and abdominal wall and stretched by pulling its ends brought outside of the abdominal wall. The ribbon is introduced pulling it inside through two holes produced in soft tissues with needle-shaped member using tubular envelope prefitted on the needle-shaped member. The tubular envelope is left in the hole when pulling the needle-shaped member from the hole in the direction reversed with respect to PIERCE direction. Ribbon is pulled into the hole in the introduced tubular envelope drawing the corresponding end. Then the tubular envelope is removed from the body in the direction of ribbon end. Surgical instrument has implantable ribbon and rod having handle on the first end with curved needle-shaped member on the second end and through hole on the free end with an ear which sizes are enough for passing from the internal surface of the vagina wall above the posterior back side of the pubic bone to the external surface of the abdominal wall. The instrument additionally has removable tubular envelope which dimensions allow the ribbon under implantation, moving through the hole. The removable tubular envelope is fittable over curved needle-shaped member as far as possible from the rod side to the prominent free end of the curved needle-shaped member projecting from the tubular envelope.

EFFECT: enhanced effectiveness of treatment; reduced instrument production costs; simplified design.
