Systems and methods for image detection during grasping and stapling include an end effector having a first jaw and a second jaw, an imaging sensor mounted to the end effector and configured to capture images of a material graspable by the end effector, and one or more processors coupled to the end effector and the imaging sensor. The one or more processors are configured to receive the images from the imaging sensor, determine one or more properties of the material based on the images, and display the one or more properties of the material on an interface. In some embodiments, the end effector is part of a medical tool and the material is anatomical tissue. In some embodiments, the end effector further includes one or more of a stapling mechanism configured to staple the material or a cutting mechanism configured to cut the material.

A surgical fastener applier including a housing containing a compartment, an elongated member extending distally from the housing, first and second jaws and a firing mechanism positioned within the housing. The firing mechanism is movable between a first position and a second position to effect firing of fasteners into the tissue clamped between the first and second jaws. A cover on the housing is openable to access the compartment. A power pack is removably loadable into the compartment, the power pack having a motor and an engagement member removably engageable with the firing mechanism within the compartment when the power pack is loaded into the compartment to effect movement of the firing mechanism from the first position to the second firing position.

A surgical instrument comprising a staple firing drive and an articulation drive is disclosed. The articulation drive is selectively engageable with said firing drive such that the articulation drive is driveable by the staple firing drive. The surgical instrument further comprises a sensor system configured to assess whether the articulation drive is engaged with the staple firing drive.

A minimally invasive surgical device characterized by comprising: a manipulable handle (2) manipulated by a user inside a body cavity, a treatment part (3) that holds a specific swappable surgical instrument that is inserted into the body cavity and manipulated using the manipulable part, and a linking part (4), provided between the manipulable handle and the treatment part, for disposing the surgical instrument held by the treatment part in a desired orientation at a desired position within the body cavity. The linking part comprising: two or more connecting parts (7a, 7b, 8a, 8b) that are connected in series in the longitudinal direction of the linking part, and form a joint (7, 8) that enables rotation around the longitudinal axis or an axis orthogonal to the longitudinal axis; and a linking part control mechanism that moves the two or more connecting parts toward or away from each other to open or constrict the angle of the joint around the longitudinal axis and/or the angle thereof around an axis orthogonal to the longitudinal axis, thereby disposing the treatment part at the desired position and in the desired orientation within the body cavity.

A surgical tool configured for operation in connection with a robotic system. The surgical tool includes a shaft and an end effector extending distally from the shaft. The end effector comprises a first jaw member and a second jaw member movable relative to the first jaw member from a closed position to an open position in response to at least one axial motion. In addition, the surgical tool includes a motor configured to generate at least one rotational motion and a motion conversion assembly operably coupled to the motor and the second jaw member, wherein the motion conversion assembly is configured to convert the at least one rotational motion to the at least one axial motion.

A handheld electromechanical surgical device, capable of effectuating a surgical procedure, includes a handle assembly having a power source; at least one motor coupled to the power source; and a controller configured to control the motor. The surgical device includes an adapter assembly having an electrical assembly having a proximal end in communication with the controller of the handle assembly. The surgical device includes a reload configured to selectively connect to a distal end of the adapter assembly. The reload includes an annular array of staples; an annular staple pusher for ejecting the staples; and a data storage device selectively connectable to a distal end of the electrical assembly. The data storage device receives and stores performance data of the surgical device from the controller of the handle assembly.

A treatment tool includes: a first grasper; a second grasper that is rotatably provided with respect to the first grasper, the second grasper being configured to grasp a target region together with the first grasper by approaching the first grasper; a shaft configured to rotate the second grasper with respect to the first grasper; and an adjustment mechanism configured to adjust a trajectory along which the second grasper passes when the second grasper rotates about the shaft and approaches the first grasper, the adjustment mechanism including a protrusion provided according to a predicted length to be required due to variations in components.

An ultrasonic treatment tool includes: an ultrasonic oscillator in which a plurality of piezoelectric elements configured to generate ultrasonic oscillation are arranged along a longitudinal axis direction of the ultrasonic oscillator, the ultrasonic oscillator being configured to transmit the ultrasonic oscillation from a proximal end side to a distal end side of the ultrasonic oscillator; a contact receiver configured to transmit power and a control signal to the ultrasonic oscillator; and a floating structure configured to suppress transmission of ultrasonic oscillation generated by the ultrasonic oscillator to the contact receiver or dampen the ultrasonic oscillation.
