Forceps can include an outer tube, a first jaw, a second jaw, and an inner tube. The outer tube can extend along a longitudinal axis and can include a pair of outer arms extending from a distal portion of the outer tube. The first jaw can be pivotably connected to the outer tube and the first jaw can include a first flange and a second flange each located at a proximal portion of the first jaw. The first flange and the second flange can each include a proximal portion extending outward of the outer tube when the jaws are in an open position. The proximal portions can be shaped to limit extension of the proximal portions laterally beyond the outer arms.

Forceps with improved actuation include a housing and a body that is longitudinally slidable relative to the housing. The body having a peripheral flange extending outward towards the housing. A trigger includes an actuation surface configured to receive a force input from a user. The trigger further including at least one arm configured to transfer the received force input to the body. To inhibit lateral splaying of the at least one arm when the trigger is actuated, the housing includes a first control surface, such as a rib proximate the arm.

An arthroscopic or other surgical system includes a handpiece and a probe. The handpiece carries a motor drive, and the probe has a proximal hub and an elongate shaft which extends about a longitudinal axis to a working end of the probe. The hub is configured for detachably coupling to the handpiece, and the motor drive is configured to couple to a rotating drive coupling in the hub when the hub is coupled to the handpiece. A first magnetic component is carried by the hub, and a second magnetic component is coupled to rotate with the rotating drive coupling.

A forceps having a first jaw and a second jaw, where at least one of the first and second jaws is capable of moving between an open position and a closed positions. The forceps including an inner shaft located within an outer shaft and extending along the longitudinal axis, and a drive bar coupled to and extending distally from the inner shaft. The drive bar including a pair of drive bar struts extending from a distal portion of the inner shaft and positioned laterally inward of at least one of first and second set of flanges of the first and second jaws. A drive pin is securable to the pair of drive bar struts and the drive bar is translatable within the outer shaft to translate the drive pin to move the first jaw and/or the second jaw between open and closed positions.

A system for driving an ultrasonic device for bone cement removal and/or osteotomy operations comprises a control unit, a memory unit, and a connector for connecting together the control unit and a handset of the ultrasonic device. The control unit is configured to send a signal to the handset, receive from the handset a response to the signal sent, and check an operating condition of the ultrasonic device based on this response. Related device, method and computer program are also disclosed.

An electrically insulating insert for detachable connection to the distal end region of a resectoscope shaft, characterized in that the insulating insert has a hollow portion with an elongate cavity for the passage of pass-through instruments, and that the insulating insert has fastening means for detachable connection to the resectoscope shaft. An electrode instrument is connected to this insulating insert and to a resectoscope including the same.

Forceps including a housing, a first body, a second body and a drive shaft. The first body has a passageway extending therethrough. The drive shaft extending through the passageway and connected to the first body such that the first body and the drive shaft are slidable with respect to the housing to drive jaws located at a distal portion of the drive shaft between an open position and a closed position. The second body having a second passageway. The drive shaft extending through the second passageway such that the second body is guided by the drive shaft and is slidable relative to the first body and the drive shaft to displace a blade shaft between a retracted position and an extended position.

A forceps having at least a first jaw with a longitudinal axis is disclosed. The first jaw can include a body portion, a first flange, a second flange and a cam pin. The first flange can define a first cam slot with a longitudinal extent along the longitudinal axis. The second flange can be spaced from the first flange a distance transverse to the longitudinal axis of the first jaw and can have a second cam slot. The cam pin, with a longitudinal axis, can be moveably secured within the first cam slot and the second cam slot. A diameter of the cam pin can be less than a width between a first longitudinal edge that defines a first side of each of the first cam slot and the second cam slot and a second longitudinal edge that defines a second opposing side of each of the first cam slot and the second cam slot so that the cam pin is moveably received by both the first cam slot and the second cam slot. With the first jaw pivoted to at least a first position, the cam pin and first flange can be configured such that the first longitudinal edge is contacted by the cam pin but the second longitudinal edge is spaced from the cam pin. The cam pin and second flange can be configured such that the first longitudinal edge is spaced from the cam pin but the second longitudinal edge is contacted by the cam pin.

A surgical tool can include an outer tube, an end effector, an inner tube, and a distal plug. The outer tube can extend along a longitudinal axis and the outer tube can include a pair of outer arms. The end effector can be connected to the outer arms. The inner tube can be located within the outer tube and can extend along the longitudinal axis. The inner tube can be connected to the end effector and the inner tube can be translatable along the outer tube to operate the end effector. The distal plug can be securable to the outer tube between the outer arms proximal of the end effector. The distal plug can include a wire routing bore extending therethrough.

An electrode assembly is provided for use in a resectoscope, the electrode assembly comprising an elongate shaft, at least one arm, first connection means for connecting the arm to a source of electrosurgical energy, and a tissue treatment element at the end of the arm. The arm includes a suction lumen extending from a proximal end to a distal end, the distal end of the suction lumen terminating in the general region of the tissue treatment element, and the proximal end of the suction lumen including second connection means for connecting the suction lumen to a source of suction.
