The present invention accordingly provides a device or apparatus for manipulating matter in a confined or inaccessible space, comprising manipulator means at least partly constructed of one or more bent or twisted elongate shape memory alloy members (14) having pseudoelasticity at the intended manipulation temperature, and a hollow housing (10) (preferably of elongate tubular form) or cannula capable of holding at least the shape memory alloy member(s in a relatively straightened state, and actuating means (20, 22) for extending the shape memory alloy member(s) from the housing (10) to manipulate matter within the said space and for withdrawing the shape memory allowy member(s) into the housing, the arrangement being such that the shape-memory alloy member(s) 14 bend(s) or twist(s) pseudoelastically in a lateral or helical sense to manipulate the matter on extending from the housing at the said manipulation temperature, and become(s) relatively straightened on withdrawal into the housing at the said temperature. Preferably the invention provides such a device or apparatus which is of elongate form for surgical manipulation of matter within a living body, and which has the manipulator means at its distal end with the shape memory alloy member(s) having pseudoelasticity at the temperature to be encountered within that body, and wherein the actuating means is operable from the proximal end of the device. |

A first member rotatably couples the first lever to the second lever, a second member couples the cutting lever to the first lever and/or the second lever, where the second member provides a pivot for the cutting lever to rotate relative to the second lever. A means for rotating the cutting lever relative to the second lever to move the top edge toward or away from the bottom edge when the first lever's first end is moved relative to the second lever's first end is provided, where the first lever, the second lever, and the cutting lever are arranged in a side-by-side configuration such that each has a longitudinal axis that is parallel to each other when the cutters are in a closed position. | ||||||

| A cutting device configured to cut drywall structures includes an elongate body of generally curved geometry, a forearm holding section positioned at a distal end of the elongate body, multiple retractable knifes hingedly connected at an opposing distal end of the elongate body, and a hand holding section positioned substantially at a mid-portion of the elongate body, where a user supports a forearm of the user at the forearm holding section, and holds the hand holding section using hands to cut the drywall. | ||||||
| 170 | Manual Pliers | US15291688 | 2016-10-12 | US20170113367A1 | 2017-04-27 | Roman Zinser |
| The invention relates to manual pliers (1) which comprise a fixed cutting jaw (26) and a movable cutting jaw (23). The manual pliers (1) comprise a first maximal opening position in which it is possible to run through a working stroke part caused by the closure of the hand levers (2). In the first maximal opening position the latching lever (16) and a pushing lever (19) engage with a toothing (32) of the movable cutting jaw (23). With the actuation of the latching lever (16) it is possible to transfer the manual pliers into a second maximal opening position in which the opening angle of the hand levers (2) is larger than in the first maximal opening position. In the second maximal opening position the latching lever (16) and the pushing lever (19) do not engage with the toothing (32) of the movable cutting jaw (23). For the definition of the two opening positions, two stops are used which are formed by the latching lever (16) and a swivel bolt of the latching lever (16). | ||||||
| 171 | Pruning Shears with Multi-Stage Action | US14724823 | 2015-05-29 | US20160345505A1 | 2016-12-01 | WEI-CHUN HSU |
| A pair of pruning shears with multi-stage actions for cutting branches with larger diameters is revealed. The pruning shears include a fixing member, a blunt member, a cutting tool, a crank member, a moveable handle, a first locking member, and a second locking member. The fixing member, the crank member and the cutting tool are pivotally connected. The cutting tool consists of a blade part and a curved teeth part. The first locking member and the second locking member are pivotally connected to the fixing member and the crank member respectively. Each locking member is disposed with a hook part, a first projecting rod, and a second projecting rod. The first projecting rod and the second projecting rod are arranged symmetrically. The first locking member and the second locking member are engaged with different teeth respectively at different stages. Thereby the pruning shears performs cutting at different stages. | ||||||
| 172 | SCISSORS | US15035035 | 2013-11-08 | US20160263753A1 | 2016-09-15 | Kazuyoshi TAKAHASHI |
| Provided are scissors with which the use of a thumb or the bending of a wrist can be reduced, and which can be used even by a hairdresser already suffering from tenosynovitis. Two half bodies are pivotably connected by a shaft support part. The first half body has a grip part, and the second half body has a trigger part. The grip part is supported by being sandwiched between the thenar and the bases of the four fingers, as well as being in contact with the palm line formed between the thenar and the bases of the four fingers. The tips of the third and fourth fingers are hooked onto the trigger part. When the third and fourth fingers are flexed, the second half body pivots in the closing direction via an extension part, and blade parts overlap one another, thereby cutting hair. | ||||||

| A pruning shears is revealed. The pruning shears include a first brake arm, a second brake arm, a blade, and at least one connection piece. The first brake arm is disposed with a first toothed part while the second brake arm is arranged with a second toothed part. The first toothed part and the second toothed part are engaged with each other. The connection piece is pivotally connected to the blade, the first brake arm, and the second brake arm. During a cutting process (pruning process), a force applied is reduced due to the connection piece pivotally connected to the first brake arm and the second brake arm. While the first and the second toothed parts are engaged with each other, the connection piece becomes a wall of the first and the second toothed parts for stabilizing the engagement of the first and the second toothed parts. | ||||||
| 174 | Snips operable by a single hand | US14273622 | 2014-05-09 | US09346178B2 | 2016-05-24 | Wen-Chiao Tsai |
| Snips include first and second handles pivotably connected to each other. Each of a pair of cutting members includes a connecting end and a cutting end. The connecting ends of the cutting members are respectively connected to distal ends of the first and second handles. A latch is pivotably mounted to the second handle and extends through a through-hole in the second handle. When the latch is in a locking position, a protrusion of the latch is located in a first section of the through-hole, a hook of the latch engages with a limiting member on the first handle, and the first handle is not pivotable relative to the second handle. When the latch is in the release position, the protrusion is located in a second section of the through-hole, the hook disengages from the limiting member, and the first handle is pivotable relative to the second handle. | ||||||

| 180 | Ratcheting tool with angular positioning handles for cutting non-metal pipe and tubing | US14050892 | 2013-10-10 | US08991059B2 | 2015-03-31 | Rigoberto Hernandez |
| Disclosed is an improved pipe cutting tool based upon a ratchet closure action wherein handles are pivotedly attached to allow successive movement of a cutting blade in response to the squeezing of the handles. The handles are also hingedly coupled to the cutting member to maintain the cutting member in a position perpendicular to the tubular item to be cut while allowing the operator to squeeze the handles at offset angles, up to and including a right angle cut. The hinged handles allow for offset operation without forgoing the ease of operation by the consumer or causing a large reduction in the mechanical advantage. A ratchet allows sequential advancement of a cutting member toward a tubular shaped jaw that holds the item to be cut. | ||||||
