摘要： A dental scaler system consisting of an ergonomically designed body and interchangeable tip assemblies designed to minimize fatigue due to prolonged strain from instrument grip and use. The device has a centrally located opening shaped to receive the index finger for a comfortable reduced strain grip. The opening is shaped such that it is possible to maneuver and rotate the device around the index finger allowing the user to change from one working end to the other in a single handed manner while continuing to hold the device. The device is designed to utilize detachable and interchangeable tips including spacers to adjust the overall length of the device or as a one piece unit with fixed instrument tips.

摘要： A compact, low-profile surgical retractor (100) avoids the need for a bulky frame. The retractor includes retractor blade components (110, 120, 130, 140, 150, 160) joined pivotally. A cable (170) is guided by each retractor blade component. A winding mechanism (180), such as a spool, is carried by one of the retractor blade components (120) for winding up the cable to cause the retractor blade components to transition from a closed position to an open position. The winding mechanism may be actuated by a detachable handle (200). The retractor blade components may be unitary, injection-molded pieces. The retractor blade components may be fixed pivotally, such as by pins, or pivotally joined by living hinges. A less-invasive surgical method is also provided in which the retractor is inserted into the body through an incision.

摘要： A surgical clamp includes a clamp head, and a first jaw and a second jaw, each mounted to the clamp head for movement toward and away from each other. The clamp also includes an operative mechanism coupled to the proximal end of at least one of the first jaw and the second jaw, and an actuating structure connected to the operative mechanism for imparting a parallel opening movement to at least one of the first jaw and the second jaw from a first position to a second position where the first jaw and the second jaw are spaced apart and parallel to one another, the actuating structure selectively imparting further scissors-like opening movement to at least one of the first jaw and the second jaw from the second position to a third position where the first jaw and the second jaw are spaced apart a distance greater than that of the second position.
