  • Patent number: 7572253
    Abstract: In order to rotate and move an arm of a slave which supports a needle-holder, the rotation and movement of a pen-shaped operating section (31) caused by the fingers of the operator's hand are directly transmitted as the rotation and movement of the needle-holder, as sensors for detecting the rotation and movement of the operating section, an X-axis torque sensor, Y-axis torque sensor, Z-axis torque sensor, and a rotation detecting potentiometer (33) are installed thereon. As a result, the rotation and movement of the pen-shaped operating section (31) caused by the fingers of the operator's hand are transmitted as the rotation and movement of the needle-holder in optimum proportions through a computing section. Therefore, when the needle-holder is to be finely moved, a subtle motion of the fingers of the hand can be satisfactorily transmitted. Thereby, it is possible to provide a surgical operation device capable of doing minute surgical operations with ease.

  • Publication number: 20040181185
    Abstract: A device is designed for scraping off disordered part at the surface of soft tissues, particularly for removing diseased surface tissues deep in an ear canal. The device mainly includes a handle having a battery-powered motor mounted therein, and a scraper in the form of a hollow tube having two open ends, a front end of which is a scraper tip having a saw-toothed edge, and a rear end of which is connected to a front end of the handle and an external suction hose. When the motor is actuated, the handle and accordingly the scraper are vibrated to result in a circular motion of the scraper tip, enabling the scraper tip to scrape and exfoliate diseased tissues while the suction hose synchronously sucks effused blood and exfoliated tissues, so that the treated area is clean and easy for observation during an operation.

  • Patent number: 5997551
    Abstract: A plunger-in-tube surgical instrument that, by the plunger's (10) back and forth action, can expose or guard a penetrating, cutting head (13) to safely enter body cavities, can allow rapid air introduction into said body cavity, can open a specialized aperture (5 and 6) on the tube (1) wall for introduction and restraint of pendunculated tissues, can severe said tissue attachments by shearing between plunger and tube wall, cutting guillotine-fashion (FIG. 5) along said tube wall, and just pulling back to severe attachments against a sharpened spot (7) on said tube wall, can interchange first plunger with other specialized plungers while pedunculated structures are restrained by said tube, and can store severed structures in said tube for removal from said body cavities.

  • Patent number: 5935137
    Abstract: An apparatus and method for human female sterilization. The apparatus includes an occlusive device configured from an elongate tubular member having a central lumen and a flange formed at the proximal end. The occlusive device is formed with a plurality of flexible ribs configured to provide a plurality of seals within the interstitial portion of a Fallopian tube. A valve member is preferably disposed within the lumen of the tubular member. The occlusive device may further include a plurality of copper rings disposed between the ribs of the tubular member, or ribs may be coated with a material containing copper. The method includes placing the occlusive device within a delivery catheter having a lumen and placing the distal end of the delivery catheter within the uterus. After the occlusive device and distal end of the delivery catheter are placed in the Fallopian tube, the occlusive device is removed from the delivery catheter and ejected into the Fallopian tube.

  • Patent number: 5674228
    Abstract: A clamp and method for castrating livestock is provided. The clamp includes a pair of opposed elongated members, each having a curved jaw and a handle. The members are pivotally coupled so that the clamp may be selectively moved from an open position, wherein the jaws are maintained in close spatial proximity. The clamp also includes a locking mechanism whereby the clamp can be selectively locked in the closed position. At least one handle of a member is adapted to be engaged with the chuck of a power rotary device. The method includes first making an incision in the scrotum. The testes are pulled away from the scrotum and the scrotum is pushed upwardly to allow unobstructed access to the spermatic cords. The jaws of the device are then positioned over one spermatic cord and locked in the closed position. The rotary device is then activated thereby rotating the clamp and causing the spermatic cord to twist sad break. The process is then repeated with respect to the second testis.

  • Patent number: 5591176
    Abstract: A clamp is provided for castrating livestock. The clamp includes a pair of opposed elongated members, each having a curved jaw and a handle. The members are pivotally coupled so that the clamp may be moved between a released position with the jaws spaced apart and a clamped position with the jaws spaced apart slightly. The clamp also includes a locking mechanism so that the jaws can be locked in the clamped position. At least one of the members includes a shank for engagement with the chuck of a power rotary device such as a drill. The clamp is used to rapidly twist the spermatic cord to cause it to break and form a knot which reduces bleeding from the cord.

  • Patent number: 5190560
    Abstract: An instrument for castration by ligating and severing blood and seminal vessels. A pistol-shaped tool comprises a hollow body forming a barrel and a hand grip. A yoke pivotally mounted in the cavity of the grip is pivotally connected to a trigger, ligating means and severing means. The vessel to be ligated and severed is positioned in a slotted area at the muzzle of the barrel. The initial pulling of the trigger toward the grip causes blade guards connected to the severing means to surround the vessel or vessels. Further movement of the trigger toward the grip actuates the ligating means to push a ligature from a ligature container and around the vessels. The ligature is forced through ligature compressors which press the locking ligature onto the vessels. Final movement of the trigger toward the grip moves the severing means to force a blade through the vessels.
