Abstract: A connector assembly for connecting a surgical saw blade to a housing of a surgical instrument. The connector assembly allows a surgeon to align, insert and lock the surgical blade in the collet of the surgical instrument without any special tools, and further provides a stable and robust platform for mounting the surgical saw blade thereto. The connector assembly includes a cam lever assembly for allowing the user to apply a clamping force to the surgical saw blade with minimum actuation force.

Abstract: A cannula having a bore extending along a length thereof. The cannula includes a vent hole. A plug with an air passage may be inserted within the vent hole such that the air passage is in fluid communication with the bore of the cannula.

Abstract: A connector assembly for connecting a surgical saw blade to a housing of a surgical instrument. The connector assembly allows a surgeon to align, insert and lock the surgical blade in the collect of the surgical instrument without any special tools, and further provides a stable and robust platform for mounting the surgical saw blade thereto. The connector assembly includes a gripper having a centrally located bore and a pair of opposing shelves. A shaft having shoulders is slidably fitted within the bore of the gripper. The shoulders communicate with ledges of the shelves to prohibit movement of the finger gripper. This same mechanism also prevents movement of a surgical saw blade, once inserted within the slot of the shaft, from becoming dislodged or ejected from the connector assembly. A biasing spring biases the gripper in a first position, but the gripper can move between the first position and a second position.

Abstract: A connector assembly for connecting a surgical saw blade to a housing of a surgical instrument. The connector assembly allows a surgeon to align, insert and lock the surgical blade in the collet of the surgical instrument without any special tools, and further provides a stable and robust platform for mounting the surgical saw blade thereto. The connector assembly includes a tapered conical shaped sleeve which is positioned within the housing and rotatable in both a clockwise and counter-clock wise direction. A pair of grippers are mounted within the connector assembly and engage the surgical saw blade when the tapered conical shaped gripper sleeve is rotated in a first position. A sternum guard is also mounted to the housing.

Abstract: A power assisted liposuction/lipoinjection handpiece includes a handle (12) which provides power to reciprocate a cannula (10) back and forth during surgery. The cannula (10) can be connected to the handle (12) by a connector (24) that is affixed to, integrally formed with, or selectively joinable to a reciprocating member (14). Benefits in sterilization, distribution and surgical use can be realized when the cannula (10) and connector (24) are joined together, such that the surgeon merely needs to remove the cannula (10) from the package and connect it to a reciprocating member of a powered handle (12). The handle (12) may be configured such that the reciprocating member (14) is selectively detachable; thereby, allowing the handle (12) to be used for additional surgical procedures such as sawing or drilling. A vacuum hose (26) is connected to the cannula (10) such that vacuum pressure can be exerted through the cannula (10) for aspirating severed fat tissue.

Abstract: A surgical instrument having a locking mechanism for preventing an output shaft of the surgical instrument from rotating and a further locking mechanism for mounting a battery pack to a distal end of a housing of the surgical instrument. The surgical instrument further includes a clutch mechanism for limiting the torque of a drive shaft of the surgical instrument. The locking mechanism for preventing the output shaft from rotating includes a locking switch which mates with a locking cap disposed on the output shaft. The locking mechanism for mounting the battery pack to the housing includes a groove at the distal end of the housing and a retaining ring which engages the groove when the battery pack is mounted on the housing. The clutch mechanism includes a clutch plate that interfaces with both the output shaft and the drive shaft and prevents failure of the motor shaft.

Abstract: A two stage releasing interlocking system for mounting a medical device tool which includes a jaw head having an aperture. A collet having an upper portion and a lower portion is rotatably mounted within the jaw head. The upper portion of the collet has an aperture and is substantially aligned with the aperture of the jaw head. A moving means moves the lower portion of the collet into an opened position and a closed position with respect to the upper portion of the collet. Actuating means prevents the moving means from moving the lower portion of the collet into the opened position when the actuating means is in a first position and permits the moving means to move the lower portion of the collet into the opened position when the actuating means is in a second position.

Abstract: A surgical instrument having a locking throttle mechanism. The throttle is pivotally mounted to a wand-type housing by a hinge, and the housing includes a tool tip and a connecting mechanism. The throttle fits in an indented portion of the housing when it is in an ON position. An actuating switch is placed under the throttle and is controlled by a sliding grip/safety switch located on the throttle. A slidable locking mechanism is placed within a cavity of the throttle and may be moved between a locked position and an unlocked position. In the locked position, a portion of the slidable locking mechanism communicates with a locking cavity proximate to the lip of the housing. A spring is located between the throttle and the housing and urges the throttle into an OFF position and is compressed when the throttle is advanced downward towards the housing.
