A surgical instrument operable to sever tissue includes a body assembly and a selectively coupleable end effector assembly. The end effector assembly may include a transmission assembly, an end effector, and a rotational knob operable to rotate the transmission assembly and the end effector. The body assembly includes a trigger and a casing having a distal aperture configured to receive a portion of the end effector assembly. First and second coupling mechanism portions cooperatively couple the end effector assembly to the body assembly for use. The coupling may mechanically and/or electrically couple the end effector assembly to the body assembly via various coupling mechanisms. For instance, a threaded slip nut may couple to threads within the body assembly. In one configuration, the end effector assembly may have locking tabs that rotate into rotational recesses in the body assembly. The locking tabs may include electrical contacts and/or optically perceivable indicators.

A time-based wireless pairing operation between a medical device, such as a patient bed, and a wall module in a patient room is initiated in response to a power plug of the medical device being plugged into a power receptacle carried by the wall module. Times determined by timers of the medical device and the wall module are compared by the wall module or by the medical device so that wireless pairing occurs only with the medical device that was plugged into the wall module. Different types of plug detectors used in the wall module to detect connection of the power plug include optical detectors, mechanical switches, and current sensors.

An apparatus for operating on tissue includes a body, a shaft, an ultrasonic blade, and an acoustic assembly. The shaft extends distally from the body. The blade is disposed at the distal end of the shaft. The acoustic assembly comprises an acoustic waveguide coupled with the blade, a piezoelectric transducer element, a fastener, and a coupling member. The transducer element defines an inner diameter surface and an outer diameter surface. The fastener is configured to secure the transducer element relative to the waveguide. The coupling member is configured to provide electrical continuity between the fastener and the inner diameter surface of the transducer element. The outer diameter surface of the transducer element includes an annular recess. Another coupling member is configured to provide electrical continuity between the annular recess of the piezoelectric transducer element and a power source while permitting the piezoelectric transducer element to rotate relative to the body.

A biopsy system having a lateral tissue access port includes an energy based tissue penetration system that can advantageously penetrate hard tumors, improve hemostasis, and provide greater tissue access. The energy based tissue penetration system has a vibrational member removeably disposed within the biopsy system, and a distal tip of the vibrational member extending from the biopsy system for tissue penetration. A sleeve is located between the vibrational member and the lateral access port to prevent tissue contact with the vibrational member through the lateral access port.

An electrosurgical instrument can comprise a handle, a shaft, and an end effector, wherein the end effector can be rotatably coupled to the shaft by an articulation joint. The instrument can further comprise a drive member and the articulation joint can comprise flexible support members which can be configured to support the drive member. The instrument can further comprise supply wires electrically coupled to electrodes in the end effector and a wire tensioning device configured to prevent the supply wires from accumulating slack within the articulation joint. The drive member can comprise a plurality of flexible layers wherein some of the layers can be comprised of an electrically insulative material and other layers can be comprised of an electrically conductive material which is in electrical communication with a cutting member in the end effector and/or electrodes positioned within the end effector. A surgical instrument can comprise a handle and an end effector, wherein the end effector can comprise first and second jaws which can be opened and closed in order to capture tissue therebetween. The surgical instrument can further comprise a shaft extending between the handle and the effector and means for articulating the end effector relative to the shaft. The articulating means can comprise a portion of the shaft which is rotatable about a first axis in order to articulate the end effector about a second axis. In at least one embodiment, the shaft can comprise a first portion including a cam and a second portion including a cam follower, wherein the rotation of the second portion and the interaction of the cam and cam follower can cause the second portion to pivot relative to the first portion.

A surgical instrument is provided that can comprise and end effector including two jaws and a cutting member configured to move between the jaws. In at least one embodiment, one or both of the jaws may be flexible, such that a jaw is configured to flex when gripping tissue. Further, at least one of the jaws may include a thin cross-sectional area such that the jaw flexes when gripping tissue. Additionally, in at least one embodiment, one or more compression elements may extend from the cutting member and may be configured to cause the jaws to close when the cutting member is advanced. The compression elements may comprise a roller and/or a low-friction material. Moreover, in at least one embodiment, one or both of the jaws may be precurved, away from the cutting member's longitudinal axis. Accordingly, in various embodiments, the overall force required to advance the cutting member and/or close the jaws may be reduced.
