A through hole or passage is made in the rod, which is open at the slot in the head and at the side rod surface. The rigidity of the leg decreases from the zone of interconnection with the web towards the leg end. A method of and forceps for removal of such a surgical staple are also disclosed.

Abstract: Described herein is an instrument, comprising a staple body and a supporting body hingedly connected thereto, both having longitudinal jaws. The staple body has staple magazines and a staple ejector. The supporting body has a die for bending the staples when suturing. A recess is provided at the base of one of the jaws on the side facing the hinge joint interconnecting the instrument bodies, the recess defining a free space between the jaws when they are brought together. The jaws are adapted to have springy elastic spacers mounted and held thereon with a possibility of subsequent releasing therefrom, said spacers being arranged on the side facing the inner compressing surfaces of the jaws so as to be stitched up together with the organs being sutured.The instrument disclosed in the present invention is successfully applied for establishing lateral anastomoses and interintestinal compression anastomoses, as well as for stitching up the mesentery.

Abstract: Described herein is a surgical instrument for suturing cutaneous tissue, especially scar tissue, when stitching on skin grafts, said instrument comprising a supporting body and a staple body which are hinged to each other so as to be capable of being brought together or apart. A staple magazine is provided on the staple body of the instrument, and an ejector is provided for driving the staples from the staple body into the stitching unit. The stitching unit incorporates a single needle-shaped die with an L-shaped needle, said needle being mounted on the supporting body, and a slot formed at the end of the staple body through which the die needle passes when suturing. The needle-shaped die has two recesses, one of which communicates with the magazine through the groove provided in the supporting body, while the other of which, upon bringing the instrument bodies together, is located against a special groove in the staple body, communicating with the staple magazine and with the base of the slot.

Abstract: The instrument has a separable body composed of two oblong interlinked members, each of them carrying at one of its vacant ends a detachable split bush adapted for the element being sutured to pass through the interior thereof and arranged across the longitudinal axis of the respective instrument body member. The bushes have flanges on the ends facing each other, each of the flanges having an open annular slot in the surfaces facing each other, and an opening made in the lateral face of the flange, the opening being communicated with the slot and with the tube that freely runs throughout the overall length of the instrument body and extends from it outwards so as to be connected to the vacuum device. The slots and openings in the bushes establish, along with the tubes, a system of air evacuation from the suturing zone, which is discarded along with the bush after the suturing procedure. One of the bushes has passages for the staples, while the other bush, a die for the staples to bend.

Abstract: The device for administering medicinal preparations comprises an isolated capsule subdivided into a chamber for a first medicinal preparation and a chamber for a second medicinal preparation. Coaxially inside said isolated capsule concentrically therewith is the piston which bounds said chamber for the first medicinal preparation. Made fast on said piston is the injection needle having the hole located at the base of said piston. Provision is made in the device for a mechanical actuator of said piston, which is a spring-opposed pushrod located inside the housing which also accommodates the retaining member for said spring-opposed pushrod. Said chamber for the second medicinal preparation is arranged concentrically with said chamber for the first medicinal preparation so as to embrace the latter. Said isolated capsule is mounted traversably inside said housing, while communication between both of said chambers is established upon a positive extension of said isolated capsule from said housing outwards.

Abstract: The device for injection of medicinal preparations, according to the invention, comprises a changeable isolated capsule, an injection needle, and a drive to move pistons, made in the form of a spring-loaded pusher located inside the housing which supports the changeable isolated capsule. The housing has a stopping member to arrest said spring-loaded pusher. Inside said isolated capsule, installed coaxially therewith and with each other are a main piston closed by a partition on the side facing the chamber holding the first medicinal preparation and an additional piston. The partition is movable. The injection needle is installed inside the isolated capsule, fixed on the additional piston, and it in use passes through said partition, and has an aperture in the zone of the partition on the side of the chamber holding the first medicinal preparation. The additional piston is located in the channel of the main piston and limits the chamber for the second medicinal preparation.
