  • Patent number: 5364410
    Abstract: Percutaneous suture externalizer devices are disclosed which grasp, secure and externalize sutures from within an abdominal or thoracic cavity. The suture externalizer devices include a thin tubular sheath with a penetrating point and a hook rod slidable within the sheath. The hook rod is slidable between an extended position and a retracted position. The hook rod is biased to the extended position. In the retracted position, a suture grasped within the hook is snugly held between the hook rod and the inner wall of the sheath, providing a positive means of securing the suture during externalization. An alternative embodiment utilizes a hollow tubular hook rod that can also be used to insufflate the abdominal or thoracic cavity. The alternative embodiment utilizes a valve to control the flow of gas through the hook rod, into and out of the cavity.

  • Patent number: 5254125
    Abstract: An instrument for grasping and incising the scrotum of an animal. The instrument has a barrel, a spring-loaded rod within the barrel, a pair of forceps members attached to the rod and a knife housing with a spring-loaded knife at the forward end of the barrel. A spring-biased latch member is provided to hold the knife in a cocked position. A trigger is attached to the barrel to cock the rod in a forward position with the forceps members extending forward through the knife housing and to release the rod for rapid movement rearward in the barrel. With the knife and rod cocked, the forceps members are applied to the scrotum of an animal. The trigger is then pressed to release the rod and forceps members rearward. The rearward movement of the forceps members draws a portion of the scrotum into the knife housing behind the knife. The final rearward movement of the rod causes the latch member to be tripped, and the knife is released to incise the scrotum.

  • Patent number: 5207690
    Abstract: An arrangement including a suction pump, a pipette, an application tip and a plurality of ligating rings which are carried on the application tip. The application tip is disposed in cooperative relation with the pipette so that the ligating rings may be transferred from the adapter tip to the pipette while being gradually stretched. The pipette is disposed in an incision exposing the ovarian sack of a small mammalian creature, whereupon a suction or vacuum is generated by the pump to capture the ovarian sack, after which a ligating ring is slipped off of the pipette and contracts to ligate said captured sack. This enables resorption of the ligated ovarian sack into the creature and stabilization of hormonal activity as is desired for experimental purposes.

  • Patent number: 5188637
    Abstract: A metallic clip, to fasten two ends of latex surgical tubing under tension when used as a ligation element especially as in the castration of animals, provides a cylindrical tubular element defining an axially aligned slit through its periphery, with each side portion adjacent the slit defining angulated slots extending spacedly inwardly from a first end of the clip in a diverging fashion, to receive tubing ends. The clip defines an outwardly extending alignment protuberance inwardly from the second end of the clip in a position diametrically opposed to the peripheral slit. For use two latex surgical tubes are passed through the clip channel and one end portion of the tube is inserted in each slot. After tensioning the tubing, the clip is mechanically deformed, preferably by a tool created for such purpose, to bend each body portion between the slot and the slit inwardly to fasten each adjacent tube portion between that clip portion and the opposite side wall of the clip.

  • Patent number: 5002552
    Abstract: A plastics clip for performing sexual sterilization comprises two jaws each having a lining of silicone rubber, hinged to move from an open position to a closed position, in which a Fallopian tube is occluded. A catch mechanism biasses the jaws apart when the clip is open, by means of pressure from a resilient finger on a cam profile attached to the upper jaw. The finger and underside of the cam profile engage when the jaws reach their closed position, and lock the jaws closed. During closure, a resilient tongue formed on the upper jaw and a projection forming a hook on the lower jaw prevent the tube from escaping. Due to the biassing, the clip will spring back open during application if not sufficiently closed to engage the catch mechanism. In conjunction with the biassing, two moulded recesses and the shaping of the clip in a region adjacent the hinge end the clip to be located firmly in an applicator before closure.

  • Patent number: 4960422
    Abstract: A depilating appliance comprises a rotary depilation roller formed by a series of blades placed side by side. The blades of the roller are movably mounted on their driving shaft so as to be capable of pivoting about an axis perpendicular to the shaft. The depilation blades are actuated by means of sliding bars which are capable of producing a pivotal displacement of the blades at least once per revolution of the roller so that one blade pivots in one direction, the following blade pivots in the opposite direction, and each blade pivots about a separate and distinct axis perpendicular to the driving shaft. Two adjacent blades are thus clamped against each other opposite to the work surface, the hairs being then pinched between the two blades in order to be removed.
