(57) Abstract:Usage: in surgery. Sushnosti of the invention: rotary reciprocating motion using a needle pusher transmitted sharp, spring-loaded plates that move the needle with a large force. 2 Il. The invention relates to medicine, namely to surgery.Known surgical stapling apparatus, comprising a housing, an acicular matrix bracket store, levers and plunger.Its deficiency in the duration of the operation of the stitching, the complexity of the setting apparatus, in a relatively bulky work pieces, to use for stitching thread instead of brackets.The prototype of the selected cross-linking tool, comprising a housing with an operating part in the form of an arcuate needle guiding equipment and placed on the axis of the needle pusher.Its disadvantage is the impossibility of automatic blending of different types of seams on the entire section of biological tissues because of the inevitable slippage pulling the needle rollers of the pusher, and therefore cannot automatically fix the time of release of the needle from the tissue. In addition, the developed power is limited since it ophrenia is getting the ability to overlay different types of surgical sutures.This objective is achieved in that known device, comprising a housing with an operating part in the form of an arcuate needle guiding equipment and placed on the axis of the needle pusher, according to the invention provides a rolling bearing, oriented in opposite sides of the lugs, a rod limiters, two interconnected nuts, two parallel screw and two rows of spring-loaded wedge-shaped plates placed at an angle on the side surface of the needle pusher, made in the form of a circular sector, the rows of spring-loaded wedge-shaped plates are oriented in opposite directions, the first nut is connected with the fixed axis of the rolling bearing, and the second nut are connected by a thread with the associated with the housing and oriented parallel to the axis of the first screw, and the needle guiding equipment made in the form of the Central frame and installed on the end of the second screw holders with side frames at the ends, is placed with the possibility of movement between the rod limiters in pairs mounted on focused to a circular sector of a surface of the first nut associated with the Central frame, in which is placed the stops.The comparison of the proposed solutions with other tereotype, that allows to conclude that the criterion of "substantial differences".In Fig.1 and 2 shows a General view of the head of the machine.The head of the machine consists of a casing 1, axis 2, the needle pusher 3, the bearing 4, the stops 5, 6, pivotal limiters 7,8,9,10, two nuts 11, 12, two screws 13, 14, two rows of spring-loaded wedge-shaped plates 15, 16, the Central frame needle guiding equipment 17, the brackets 18, 19 with the side frames 20, 21.Axis 2 is to transfer the needle pusher 3 periodic high-frequency rotational reciprocating motion through an angle slightly in excess of the minimum angle between the spring pointed plates from a number of 15 or 16, which, when an arc of the needle 120aboutmay be of the order of 10about.The needle pusher 3 is designed to transmit the reciprocating movements of the two rows of spring wedge-shaped plates 15 and 16.The rolling bearing 4 enables the rotational reciprocating motion axis 2 with simultaneous forward movement of the first nut 11 and the entire head of the machine along the stitched incision.Oriented in opposite sides of the lugs 5, 6 prepyatstvuyushchimi pointed plates 15 and the second series of spring-loaded wedge-shaped plates 16.Rod stops 7,8,9,10 are intended to set the direction of the displacement holders 18, 19 with the side frames 20, 21.The first nut 11 with the screw 13 is designed to move the head of the machine along the stitched incision.The second nut 12 provides the displacement of the needle in the transverse direction from the first row spring wedge-shaped plates 15 on the second row of spring-loaded wedge-shaped plates 16 (and Vice versa) by means of the second screw 14 and attached to his butt holders 18, 19 with the side frames 20, 21.Two rows of spring-loaded wedge-shaped plates 15 and 16 are designed to force action on the needle and move it in the forward and reverse longitudinal directions when applying certain types of seams.The Central frame needle guiding equipment 17 restricts the displacement of the needle in transverse directions and is used to lock the stops 5,6.The holders 18, 19 with the side frames 20, 21 provide displacement of the needle in the transverse direction from the first row spring wedge-shaped plates 15 on the second row of spring-loaded wedge-shaped plates 16 and Vice versa, depending on the type of weld overlay.The working head operates as follows. In the initial state, the needle is located and the second series of spring-loaded wedge-shaped plates 16. Axis 2 are communicated to the rotational reciprocating motion at an angle slightly in excess of 10about, i.e. the distance between adjacent spring pointed plates of the series. These movements through a circular sector of the needle pusher 3 is transmitted to the first row of spring-loaded wedge-shaped plates 15 and second series of spring-loaded wedge-shaped plates 16. Edge spring pointed plates from the ranks of 15 or 16, located in the recessed notches of the needle, move the needle in its direct course (clockwise - to the first series of spring-loaded wedge-shaped plates 15, counterclockwise for the second series of spring-loaded wedge-shaped plate 16). During the reverse course of a number of spring-loaded wedge-shaped plates 15 or 16, a needle with them is not shifted due to the fixed Central frame 17 supports 5 or 6.In the case when a large portion of the needle is stitching the fabrics, the return stroke of the needle is prevented by compression needle stitched fabrics. After making a needle full turn 180aboutin the longitudinal direction and the location again in the upper position remote from the stitching fabrics, axis 2 stops its movement and at this point, the rotation of the first screw 13 causes the first nut 11 with associated with what camping rotational reciprocating motion axis 2, and the working cycle is repeated. If you want to change the direction of longitudinal movement of the needle (clockwise or counterclockwise), which is associated with selection of a desired type of surgical suture, the rotation of the second screw 14 at the upper position of the needle remote from the stitching fabrics, with the help of side frames 20 and 21 sliding on the rod limiters 7, 8, 9, 10, moves the needle from the first series of spring-loaded wedge-shaped plates 15 on the second row of spring-loaded wedge-shaped plates 16 or Vice versa. After stopping the rotation of the second screw 14 working cycle is repeated.Thus, the use of the proposed device reduces the operation time of cross-linking allows you to develop a sufficiently large mechanical force on the needle in the longitudinal direction, provides an overlay of multiple types of surgical sutures.
