Title: Surgical stapling instrument
IPC: A61B17/068
Filed: 1971-12-14
Abstract: 1373227 Surgical stapling apparatus UNITED STATES SURGICAL CORP 14 Dec 1971 [14 Dec 1970] 58092/71 Heading B4C [Also in Division A5] A disposable cartridge for a surgical stapling instrument comprises a body 10 within which is mounted a flexible belt 30 carrying staples 36 and having a plurality of staple-contacting surfaces, a pusher element 38 being movable longitudinally adjacent the belt and having an integral staple-driving surface which normally projects into the path of the staples to engage the crosspieces thereof whereby the staples and belt are moved forwardly but which is disengaged from the crosspieces during rearward movement of the pusher element. The body 10 comprises a metallic cover 26 having an anvil 44 at its forward end and a solid projection 24 connecting the side walls. The staples are located in grooves 34 on the belt which provide the staple contacting surfaces, some grooves extending through the belt and co-operating with a projection 56 on flexible arm 54 to prevent rearward movement of the belt. Alternatively rearward movement is prevented by a spring secured to the bottom plate 28 of the body and engaging a groove 34. The staple driving surfaces are formed by flanges 40 on the pusher element which is moved by a drive mechanism so' that the staples engage ramps 60, 62 whereby they are lifted from the plane of the belt to the plane of the pusher element. Further forward movement of the element expels the staple and forms it round anvil 44, the forward end of the pusher element being stepped at 46, 48, 50 to facilitate bending the staple. The pusher element has a slot 68 engageable with a drive element 66 of a gas-powered drive unit. The unit comprises an inlet port 118 communicating with gas cylinder 110 and controlled by a spring- biased valve member 122 having a through bore 127. The member 122 engages a fixed block 130 having a bore 132 and a piston 136 slides on block 130 and is biased away from member 122 by spring 144. A drive piston 148 is connected to drive element 66 by rod 152. The instrument is operated by a trigger 158 which releases a hammer 168 to strike a flange 171 of member 122 thereby unseating it from the inlet 118 so that gas flows through bores 127, 132 to move piston 148 rapidly forwards. Gas exits from piston chamber 146 through port 134 causing piston 136 to move rearwardly to move valve member 122 into engagement with inlet 118. Drive piston 148 then moves rearwardly under the action of spring 154 and piston 136 forwardly under the action of spring 144. The cartridge is adapted for direct attachment to the stapling instrument. The bottom plate 28 of body 10 is transparent and carries indicia co-operating with the end of the belt to indicate the number of staples remaining in the cartridge.

Abstract: 1299377 Stabilising textile fibres COMMONWEALTH SCIENTIFIC & INDUSTRIAL RESEARCH ORGANIZATION 2 Dec 1969 [5 Dec 1968] 58875/69 Headings D1F and DIP Textile material containing wool, cotton, or other keratinous or cellulosic fibres has it resistance to and recovery from deformation increased within a specified range of relative humidity and temperature by an "annealing" treatment which comprises maintaining the material at 30C to 120C for more than 20 minutes while the regain of the fibres is held at a value corresponding to a relative humidity of 60% to 95%. Wool e.g. may be held at 85% r.h. and 30C for several weeks or a similar effect is obtained by maintaining the material at the same r.h. in a sealed container for about 30 mins at 100 to 120C and then cooling over a period of one hour or more. The annealing may be carriedout in a gaseous or liquid medium provided that the necessary about of water is present to maintain the desired regain in the fibres. Stabilization treatment. The annealed fibres may be molecularly stabilised by a reagent which forms permanent cross-links between reactive groups in the fibres under conditions which do not de-anneal the fibres. The reagent may be a polyfunctional compound having two or more functional groups selected from: -O- and N-methylol, O- and N- alkoxymethyl and activated C-methylol; epoxide; aziridinyl; vinyl, activated vinyl, activated 2-hydroxy ethyl and activated O-derivatives of 2-hydroxy ethyl; active halogen isocyanate and isothiocyanate; aldehyde and any of these in which the functional groups are temporarily blocked or inactivated but which can be regenerated. Alternatively the reagent may be formaldehyde or a compound producing it in the stabilising treatment. The fibres may be treated in a combined annealing- cross-linking process in which the fibres are treated with a solution of potential cross-linking agent, heat treated and the agent activated to effect molecular stabilisation. The steps of annealing and stabilisation may be repeated at least once.

Abstract: 1364910 Uncoupling railway vehicles JAPANESE NATIONAL-RAILWAYS and KAYABAKOGYO KK 22 Dec 1971 [26 Dec 1970] 59578/71 Heading B7T An automatic apparatus for releasing couplings of rail vehicles 33, Fig. 1, moving along a railway track 19, comprises an endless guide member 11 positioned above the track, a plurality of remotely controlled devices 12 suspended from and movable along the guide member, and positioning means 13 for holding each device 12 in turn in predetermined positions and for releasing them one-by-one, each device being equipped with a releasing mechanism suited to the type of coupling between the vehicles, so as to release a selected coupling during movement of the device along the guide. The outward run of the guide is directly above the track and the return run is to one side. In the positioning means 13, Fig. 5, a device 12 is held ready to go by a stop 59 and is pivoted clear of the vehicles by a rail 109, Fig. 2. When the stop is withdrawn a cylinder 72 accelerates the device to match the vehicle speed so that at the end of rail 109 the device pivots to the vertical position between the vehicles to be uncoupled and operates by battery and a pneumatic reservoir carried thereby to release the coupling. Towards the end of the outward run, the device is pivoted clear of the vehicles by a rail 110 and is positively moved by a toothed belt and a rotary actuator 99 towards the return side where a further toothed belt 107 moves the device back to a rotary actuator 100 which returns the device to the means 13. While the first device 12 is held by stop 59, a second device is held by a stop 61 and its battery and air reservoir are replenished via connections 68, 67 applied by a cylinder 69. A third device is meanwhile held by a stop 63 and the fourth and remaining devices lie one behind the other behind a stop 65. A control system involving limit switches actuated by the movements of cylinders carrying the stops, sequences the means so that when a device is released, other devices move from stop to stop along an inclined part 11a of the guide. The appar tus is particularly for use with a hump in a marshalling yard where overall control is by a computer. It is stated that each device may carry its own propulsion mechanism and speed control mechanism in which case the device moving apparatus arranged on the guide, except for cylinder 72, may be dispensed with.

Title: Improved electrically heated apparatus and method and material
IPC: A61B18/20
Filed: 1979-04-04
Abstract: A self-regulating resistive electric heating element consists of a two- layer laminate, the first layer having high electrical conductivity and low magnetic permeability and being itself, as described a laminate comprising a sandwich of cutting steel 21, Fig. 2, between two layers of metal 23 such as silver or copper, and the second layer 25 having a high permeability and a low conductivity and being of ferromagnetic material. If an r.f. current is passed through such an element using an additional conductive layer 29 insulated 27 from the element as the return conductor, at low temperatures the majority of the current will pass, owing to the skin effect, through the thin ferromagnetic layer and thereby cause heating, but as the temperature rises towards the Curie point of the ferromagnetic layer, its permeability falls, the skin depth increases, and as a consequence less current is carried by the ferromagnetic layer and more by the other layer 21, 23, which results in a net drop in the rate of generation of heat. As described the composite heating element is sharpened to a cutting edge 15 and forms part of a surgical scalpel. <IMAGE>
