Atraumatic suturing NEEDLE FOR SMALL Access and trocar RAS

摘要

The invention relates to medical engineering and can be used as a tool for suturing tissues in all fields of medicine, including, for closing trocar incision wound and a small length, in the course of minidostupnyh and laparoscopic surgery. Summary of the utility model is that the atraumatic suturing needle for small accesses and trocar wounds actuator comprises a needle with a hole and piercing tip, and the retaining device. The needle is made as a 2-stage flat rod with a handle at the top end, the bottom, the thin end of which is tapered and includes an open hook-shaped lug. The middle part of the rod is thickened relative to the lower end of the upper rod portion is thickened relative to the middle portion and the end adjacent to the middle portion comprises the key. The needle, with the union nut on the upper end of the rod and a coil spring placed on the middle part is mounted in the retaining device, which housing. The housing is formed by a series connection of two longitudinally installed tubes of different diameter, wherein the inner diameter of the upper portion of the housing corresponds to the outer diameter of the top of the rod. On the outer surface of the upper end of the body is threaded, is formed in the wall of a longitudinal groove opening into the end face. The middle third of the upper part of the body, on an annular thickening, fixed abutments in the form of diametrically arranged pins at the boundary of the lower housing part, with an inner diameter corresponding to the outer diameter of the middle portion of the needle, the longitudinal axis of a cylindrical abutment thread retainer. The lower end of the body is connected to arm the U-shaped bracket which is mounted along the axis of the housing so that the needle, when leaving the housing through the opening in the upper arm of the bracket at its further movement, passes through a hole in the opposite lower arm, on the outer surface of which, body coaxially installed tip into a grommet. On the inner surface of the shoulder with the installed sleeve, parallel to the lines of kinks shoulder arm, a groove. On the outer surface of the bracket has a longitudinal guide groove in the form of a trough. The length of the groove in the housing is equal to the length of the tip end of the needle. The axis of the open eye, in the form of a hook on the lower, pointed end of the needle thread retainer axis, and the longitudinal axis of the guide groove in a gutter at the outer surface of the bracket located in one plane perpendicular to the axis of the stops on an annular thickening of the middle portion of the housing. Hook faces the latch arrangement side and the retainer and the web connecting arm shoulders are on opposite sides of the housing. 2 ZP f ly-5-yl.
