    摘要： The present disclosure relates to a surgical device including a body portion and an end effector. The body portion defines a longitudinal axis. The end effector is disposed adjacent a distal end of the body portion and includes first and second jaw members. At least one jaw member is pivotable with respect to the other jaw member between open and approximated positions along a first plane. Each jaw member is independently movable with respect to the other jaw member between a first position where the jaw members are aligned with the longitudinal axis and a second position where at least one jaw member is disposed at an angle with respect to the longitudinal axis and with respect to the first plane.

    摘要： An instrument drive unit comprising a motor assembly (410) including a first motor (420) having a drive shaft (422) and a first torque transducer (424) secured to the first motor, the first torque transducer including a first portion secured to the first motor, a second portion, and a body (520) interconnecting the first and second portions, characterized in that the first torque transducer includes a strain gauge (540) having an active strain sensor (542) supported on the body and configured to measure a first strain of the body as the body moves in a first direction in response to a torque of the first motor and a calibration strain sensor (544) supported on the body in a different orientation than the active strain sensor and configured to measure a second strain of the body as the body moves in a second direction in response to the torque of the first motor.

    摘要： A robotic surgical system comprising a surgical robotic arm having an end portion from which a surgical mounting device protrudes for positioning near a surgical access site on a patient, the mounting device being adapted for selectively gripping a patient access device therein, the surgical mounting device comprising a housing, a clamping assembly supported in the housing and extending therefrom, the clamping assembly including a plunger assembly supported on the housing and including a drive member disposed in the housing coupled to a middle segment disposed distal to the housing, wherein the drive member and middle segment simultaneously translate between a proximal position and a distal position with respect to the housing and a first arm supported by the housing and including a proximal portion coupled to the drive member, a second arm supported by the housing, the first arm pivotable with respect to the housing between an open position and a closed position, wherein when the first arm is in the open position, the first arm and the second arm are spaced apart relative to one another, and when the first arm is in the closed position, the first arm and the second arm are in an approximated position relative to one another, wherein the clamping assembly is transitionable between an unlocked configuration and a locked configuration, such that in the unlocked configuration the drive member and the middle segment are in the distal position and the first arm and the second arm are in the open position, and in the locked configuration the drive member and middle segment are in the proximal position and the first arm and the second arm are in the closed position, and at least one release mechanism including a contact surface disposed in the housing and an actuation member in operative communication with the contact surface, a portion of the actuation member disposed externally from the housing, wherein the at least one release mechanism is transitionable between an initial position and a release position, such that in the initial position the contact surface is spaced away from the drive member, and in the release position the contact surface is in abutment with the drive member, the release position translating the drive member into the distal position, such that the clamping assembly is transitioned into the unlocked configuration.
