摘要： ROTATABLE CURVED INSTRUMENT A surgical instrument in which a surgical tool is carried distally of a bend region in a stationary support member by an assembly that transmits proximally applied forces and selectively change the rotational orientation of the surgical tool with respect to the stationary member. In another respect, in which the stationary member does not include a bend region, a rotatable member supported by the stationary member transmits rotational force to the surgical tool to selectively change the rotational orientation of the tool, and a driver member supported by the stationary member transmits axial force to the surgical tool to operate it. In still another respect in which the stationary member includes the bend region but the surgical tool is not rotatable, a movable member supported by the stationary member is constructed to transmit a proximally applied axial force through the bend region to operate a surgical tool disposed in a distal region of the instrument.

摘要： A surgical instrument includes a rigid member that has a bend region that angularly offsets a distal region from a proximal region mounted to a first section of a base; a surgical device extending distally from a second section of the base coaxially with the rigid member carries a surgical tool distal of the bend region, and is flexible at least in the bend region to transmit force applied at a proximal end of the surgical device through the bend region to operate the surgical tool; the first base section is rotatable with respect to the second base section, allowing thy relative rotational orientation between the surgical tool and the bend region to be changed.

摘要： POWERED ROTATABLE CURVED INSTRUMENT A surgical instrument includes a first member that has an opening in its distal region for admitting tissue and that is rotatable with respect to a base from which the first member extends to allow the rotational orientation of the opening to be selectively changed with respect to the axis of the instrument. A second member is disposed within the first member to transmit force to move a cutting implement disposed at its distal end and cause it to cut tissue that is exposed to the implement through the opening. In one embodiment, a curved, rigid member is disposed coaxially with the first and second members to provide the first member with a bend region that angularly offsets the distal region (and hence the opening) from the axis of the instrument in a selected direction. The first member is relatively flexible, at least in the bend region, to allow the rotational orientation of the opening to be changed without changing the selected direction of the offset. At least a portion of the second member that is disposed in the bend region is also relatively flexible to transmit the applied force through the bend region to the cutting implement.

摘要： A surgical apparatus includes a body configured for insertion into a bore of a surgical handpiece and a latch that includes a resilient member connected to the body. The resilient member has a latching structure configured to latchingly engage a surface of the surgical handpiece within the bore.

摘要： A surgical instrument includes a support member that extends distally from a base, carrying at a distal region a window defining an opening. A surgical tool at least partially disposed in the distal region is movable with respect to the window to cut tissue extending through the opening. A shield also at least partially disposed in the distal region is movable with respect to the window to at least partially cover the opening.

摘要： An apparatus for controlling a surgical device includes a housing and a magnetic switching element mounted on the housing. The magnetic switching element includes a magnet, a magnetic sensor configured to produce a control signal for controlling the surgical device, and an actuator mounted on the housing for movement between a first position in which a magnetic field of the magnet is decoupled from the magnetic sensor and a second position in which the magnetic field is coupled to the magnetic sensor so as to change a value of the control signal produced by the magnetic sensor. The magnetic switching element may also include magnetically soft material positioned so that movement of the actuator causes relative movement between the magnet and the magnetically soft material.
