A surgical device includes an end effector having a pair of opposing jaw members and a drive beam movable longitudinally through the pair of opposing jaw members thereby approximating the pair of opposing jaw members relative to each other. The device also includes an adapter assembly configured to selectively couple to the end effector. The adapter assembly includes an actuation assembly configured to mechanically engage the drive beam and to move the drive beam longitudinally. The device also includes a handle assembly configured to selectively couple to the adapter assembly. The handle assembly includes: a power source, a motor coupled to the power source, a sensor configured to measure a force imparted on the drive beam, and a motor controller configured to control the motor to maintain constant force on the drive beam based on the force measured by the sensor during longitudinal movement of the drive beam approximating the pair of opposing jaw members closer relative to each other.

A medical device may include a handpiece having a housing and a drive system arranged within the housing. The drive system may be adapted to operate a tool in direct contact with human matter of a patient at a treatment site. The device may also include a suction system integrated into the drive system and configured to remove human matter from the treatment site. The device may also include a motor removably attached to the housing and configured for delivering rotational power to the drive system while avoiding contact with the human matter.

Surgical stapler with expandable jaw

Jaw assemblies for a surgical stapler are provided. The jaw assemblies comprise a first jaw having a first clamping surface and a plurality of staples disposed therein and second jaw assembly having a second clamping surface. The jaw assemblies can be actuated from a closed configuration in which the first clamping surface contacts or is adjacent to the second clamping surface to an open configuration in which the second jaw is pivoted away from the first jaw to a stapling position in which the second clamping surface is parallel to the first clamping surface and spaced apart from the first clamping surface. A pivoting link or sliding pivot joint can couple the second jaw to the first jaw to facilitate motion between the closed position, the open position, and the stapling position.

Systems and methods for controlling a surgical stapling and cutting instrument

Various examples are directed to systems and methods for operating a surgical instrument comprising a firing member translatable proximally and distally along a longitudinal axis between a stroke begin position to a stroke end position distal of the stroke begin position; a knife coupled to the firing member; and a motor coupled to the firing member to translate the firing member between the stroke begin position and the stroke end position. A control circuit may receive a firing signal and begin a firing member stroke by providing an initial motor setting to the motor. The control circuit may maintain the initial motor setting for an open-loop portion of the firing member stroke. The control circuit may receive firing member motion data describing a motion of the firing member during the open-loop portion of the firing member stroke and may select a firing control program based at least in part on the motion of the firing member during the open-loop portion of the firing member stroke.

Surgical apparatus

The disclosure provides a surgical apparatus comprising: a steerable member that is bendable and comprises a plurality of bending segments with channels therein; and a plurality of bending actuation wires that are arranged to pass through the steerable member and cause the steerable member to bend, the steerable member comprising at least one outwardly opening lumen through which the bending actuation wires pass.

Surgical stapler shaft formed of segments of different materials

A surgical instrument includes an end effector and a shaft. The end effector includes a first jaw movable relative to the second jaw. The shaft extends proximally from the end effector. The shaft includes a proximal coupler, a tube, and a distal coupler. The proximal coupler includes a distal coupling feature adjacent a distal end. The tube includes proximal and distal coupling features that are adjacent the respective proximal and distal ends of the tube. The proximal coupling feature is configured to engage the distal coupling feature of the proximal coupler to securably lock the tube and the proximal coupler together. The distal coupler includes a proximal coupling feature adjacent the proximal end of the distal coupler. The proximal coupling feature of the distal coupler is configured to engage the distal coupling feature of the tube to securably lock the distal coupler and the tube together.

Cooperative robotic surgical systems

A robotic surgical system includes a first automated surgical system with a first user control console; a first robotic actuator; and a first surgical system controller comprising a first processor and a first memory component configured to store a first set of processor instructions and a first set of processor data. The robotic surgical system further includes a first surgical system communication interface; and a second automated surgical system that has a second user control console; a second robotic actuator; a second surgical system controller comprising a second processor and a second memory component configured to store a second set of processor instructions and a second set of processor data; and a second surgical system communication interface in data communication with the first surgical system communication interface. The second automated surgical system is controllable through the first user control console.

Adaptive responses from smart packaging of drug delivery absorbable adjuncts

In general, adaptive responses from smart packaging of drug delivery absorbable adjuncts and methods of using smart packaging of drug delivery absorbable adjuncts are provided.

MEDICANT ELUTING ADJUNCTS AND METHODS OF USING MEDICANT ELUTING ADJUNCTS

Various exemplary devices and methods are provided for performing surgical procedures. In general, one or more adjuncts can be used in conjunction with surgical instruments. The adjunct(s) can have medicant(s) thereon and/or therein. The medicant(s) can vary depending on the desired effect of the medicant(s) on surrounding tissue. As a non-limiting example, medicant(s) can be provided to influence hemostasis, inflammation, macrophages, and/or fibroblasts. When used in conjunction with a surgical stapler, the adjunct(s) can be disposed between and/or on jaws of the stapler, incorporated into a staple cartridge disposed in the jaws, or otherwise placed in proximity to the staples. When staples are deployed, the adjunct(s) can remain at the treatment site with the staples.

Surgical Systems With Twist-Lock Battery Connection

A surgical system comprises a handpiece and a battery. The handpiece includes a body and a handpiece connector operatively coupled to the body, the handpiece connector including a first coupler. The battery includes a housing, a rechargeable cell for storing an electric charge, and a battery connector operatively coupled to the housing, the battery connector including a second coupler configured to rotatably engage the first coupler. The second coupler receives the first coupler along an axis at an initial radial position where relative axial movement between the battery and the handpiece is permitted and permits rotation of the battery relative to the handpiece from the initial radial position to a first secured radial position and a second secured radial position. Relative axial movement between the battery and the handpiece is constrained in the first secured radial position and in the second secured radial position.
