  • Patent number: 5254129
    Abstract: A hand-held instrument is disclosed for use in surgery. The instrument has a set of opposed jaws that pivot about a common axis with respect to a shaft of the instrument's handle. The upper jaw has an upper blade rigidly affixed to one side thereof. A lower blade is rigidly affixed to the shaft. When the upper jaw and upper blade are jointly forced to pivot downward by a push rod on the shaft, the rotating upper blade moves past the stationary lower blade to amputate a piece of tissue in scissor-cutting fashion. The lower jaw is simultaneously forced (by the interposed tissue) to rotate about its pivot downwardly, i.e. in the same direction as and in fixed tandem with the upper jaw. The lower jaw is held tightly against the interposed tissue via a stiff spring against which the lower jaw is biased. The spring causes the jaws to tightly clasp the tissue in plier-clamping fashion during and after its amputation from its attachment. The instrument is operated by a scissor handle arrangement.

Each hold-down surface is moveable with respect to its associated jaw away from the jaw it opposed through a wide range of distances, normally is in alignment with the cutting surface of the jaw to which it as affixed, and is resiliently biased against being so moved. Thereby, when the jaws close on a workpiece of any of a wide range of thicknesses, the hold-down surfaces of the clamps come into contact with and yieldingly remain pressed against the outer surfaces of the work piece to hold it in place as the cutting jaws impinge upon and cut through it.

  • Patent number: 5203084
    Abstract: An improved structure for a pair of scissors with pincer-clip, especially for the control of the scissors' opening angle when it's opened, and the locking of the scissors when it's closed. This pair of scissors with pincer-clip can achieve its function by moving on one side. The limitation of its opening is achieved by a O-shape buckle that connects to the spring coils on one side and a long groove of the handle on the other side. Following the opening of the pair of scissors, the O-shape buckle moves up and down in the long groove, thus controlling the opening angle of the pair of scissors by the distance between the spring coils and the pivot, and locking the pair of scissors when it's closed.

  • Patent number: 5189794
    Abstract: The structure of the shears with a tongs is that a shears overlaps a tongs. There are rivets at the end of the two handles of the two objects. The center hole of the shears cooperates with the round hole of the pivot. The hole of the overlapped parts of the tongs plates is elongated. That makes the tongs plates have more elastic space and move forward and backward in a slanting direction. The noses of the tongs propped by a tension spring can open outwards. When opening, the tongs using the ends of the handles as the axle center makes the shears open as well. Then, the noses of the tongs is a little smaller than that of the shears. When the handles of the shears are forced to clip inwards, the tongs also clips inwards. But when the noses clip the work piece, the noses stop and the edges of the shears keep cutting inwards. The tongs clips the work piece by the force of the tension spring. That the work piece does not fall down when being cut is its feature.

  • Patent number: 5105543
    Abstract: A power operated portable cutting tool for rescue work. A cutting head comprises first and second jaw members, each jaw member having a cutting edge portion adjacent one end and a shank portion adjacent the other end. The jaw members are pivotally attached together about an axis of pivot generally intermediate their ends so that the cutting edge portions are generally opposing, and so that pivoting the shank portions apart pivots the cutting edge portions of the jaw members closed. A hydraulic cylinder and piston are mounted between the shank portions of the jaw members along an axis generally transverse to the axis of pivot of the jaw members. A handle connects the tool to a hydraulic fluid supply line and to a hydraulic fluid return line. Hydraulic fluid is selectively applied to the cylinder to extend the piston and close the jaw members. The jaw members are spring biased to retract the piston and open the jaw members.
