Abstract: There is proposed a water treatment method by causing the water to be pured to flow through a first and a second compartments arranged in succession in an electrolysis cell divided by a permeable membrane into said first and second compartments. Each of the compartments accomodates an electrode, one of them being an anode, and the other--a cathode. Direct electric current is then passed through the water between the anode and the cathode, the current value being determined from the following equation:I=K.times.(C).sup.1/4 .times.Q,whereinI is the current amperage (A),C is the feed water mineralization equal to 0.1-1.5 g/l,Q is the water flow rate (1/hour), ##EQU1## the I/Q ratio being comprised within from about 110 to about 220 Coulomb/liter. The water is caused to flow successively from the anode compartment towards the cathode compartment. Once the water is discharged from the cathode compartment, it is subjected to filtering by passing the water through a bed of a porous carbonaceous material.

Abstract: The surgical forceps are composed of two movably interconnected halves (1,2). Each of said halves terminates in an oblong jaw (4,5) having an effective portion (8) with a compressing surface (17,18) which is provided with alternately arranged prongs (21) and recesses (22) corresponding to the respective recesses (22) and prongs (21) on the opposite compressing surface of the other jaw. The prongs (21) and recesses (22) are arranged on at least one longitudinal edge of the compressing surface (17,18) the recesses (22) being open towards the outer surface (19 or 20) of the effective portion (8) of the jaws (4,5).

Abstract: The sutural material consists of a base from a bio-resolvable polymer and a layer of a copolymer of N-vinylpyrrolidone with an alkylacrylate and/or an alkylmethacrylate deposited onto the base and containing an antimicrobal preparation or a mixture of preparations and having the period of its biodestruction shorter than that of the base, the thickness of this layer being equal to 0.1 to 1.0 of the base thickness.

Abstract: A device for measurement of arterial blood pressure, comprising a compression cuff with a manometer, and a pulse wave sensor interposed between the compression cuff and the patient's body surface and situated below the cuff axis square with the direction of the pulse wave propagation, said sensor being connected to a recorder and having a piezoelectric crystal plate one of whose working surfaces carries a first elastic current-conducting layer, while the other working surface of said plate carries a second elastic current-conducting layer, a first elastic electric-insulating layer being applied to the surface of the first elastic current-conducting layer, and a third elastic current-conducting layer is situated on the surface of said first electric-insulating layer.

Abstract: A surgical instrument for placing linear staple sutures comprises a body having a closed rectangular frame, each of the lateral sides of said frame being provided with a slot which is located on the inner surface of said laterial side close to the adjacent side of said frame, the axis of said slot being parallel to each of said lateral sides; a die provided with a plurality of recessess and secured on the adjacent side of the frame, the extreme recesses of said die being arranged inside the slots on the frame lateral sides; a staple head accommodated in the body; a detachable staple magazine having a plurality of staple slots and adapted to be so positioned that its portions provided with extreme staple slots should engage the slots in the lateral sides of the frame; a staple ejector, and actuators of the staple head and of the staple ejector, respectively.

Abstract: An instrument for ligating bone tissues of ribs and clavicles with metal staples includes an anvil body rigidly connected to a staple driving body which accommodates a staple pusher. The latter is mounted for reciprocation in relation to the anvil body. A hook with an anvil is mounted on the staple driving body for reciprocation in relation to the latter. The staple pusher and the hook are driven by relatively movable assemblies composed of a nut and a screw, as well as cams which translate longitudinal motion of the screws in relation to the anvil body into transverse motion of the staple pusher and the hook relative to the anvil body.

Abstract: A surgical stapling apparatus, comprising a thrust case incorporating a lengthwise groove. Said groove accommodates a magazine containing staples, and drivers of the staples, and a wedge interacting with said pushers and seating on a carriage supported in guides running along said staple case. A surface of said wedge interacting with said drivers is curvilinear, with lines tangent to the generatrix thereof and a travelling direction of said wedge located so as to constitute an angle varying gradually from 45 deg to zero between a front part of said wedge and the back part thereof in the direction of the wedge travel during stapling procedure.

Abstract: A device for uniting bone fragments comprises a rectilinear body and a contrivance for fixing it in the coapted bone fragments. The contrivance for fixing the body in the coapted bone fragments is formed by thrust members being the portions of the body located at the opposite ends thereof and having holes coaxial with the body; the holes being shaped as frustums of cones facing with their greater bases the ends of the body, and having annular grooves in the wall thereof, and cone-shaped inserts with annular ridges adapted to be introduced into the conical holes for wedging apart the body. The body has longitudinal through slots within the zones of the holes. The length of the device is less than the total length of the coapted bone fragments so as to be located fully within the bone tissues.

Abstract: The staple has two legs interconnected through a web. Each of the legs carries a rod having a pointed bottom end and a head. The head has a slot for the web to pass. 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: A surgical apparatus for the simultaneous resection of soft tissues and their suturing with metal staples comprises an anvil and a staple branches, hinge-connected and having longitudinal jaws situated one opposite the other. A longitudinal row of grooves is made on the jaw of the anvil branch for clinching the ends of staples, while slots for the staples with staple tappets placed therein are provided on the jaw of the staple branch opposite said grooves. A plank with a wedge bevel on its end intended for interaction with the staple tappets when ejecting the staples is situated in the slot of the staple branch, and is longitudinally movable therealong. Rotation shafts are set along each branch with needles set perpendicularly to them, intended for grasping the soft tissue.
