  • Publication number: 20150374449
    Abstract: A force transmitting assembly of an adapter assembly includes a rotatable drive shaft, a strain sensor, and a drive member. The drive shaft includes a proximal portion, a distal portion, and a flange. The distal portion includes a threaded portion. The strain sensor is coupled to the drive shaft and disposed adjacent the flange such that longitudinal movement of the drive shaft imparts a force on the strain sensor via the flange. The distal drive member has a proximal end rotatably coupled to the threaded portion of the drive shaft and a distal end configured to be operatively coupled to a driven member of a surgical loading unit. Rotation of the drive shaft longitudinally moves the drive member relative to the drive shaft to actuate the surgical loading unit.

  • Publication number: 20150374353
    Abstract: A housing for sealing mechanical or electrical components therewithin including first and second body portions that are coupled together along parting surfaces to define an interior space. The parting surface of the first body portion defines an opening that extends orthogonal to the parting surfaces. The second body portion includes a protrusion extending into the opening from the parting surface of the second body portion. The fastener engages the protrusion to couple the first and second body portions together. The fastener is inserted through the outer surface of the first body portion.

  • Publication number: 20150297205
    Abstract: A manual retraction tool for use with an electromechanical surgical assembly includes a handle and a shaft. The handle includes an elongated handle body having a first end and a second end, and a channel recessed within at least a portion of the handle body. The shaft includes an elongated shaft body having a tip dimensioned to be inserted into a recess of a connector sleeve of an adapter of the electromechanical surgical assembly and to effect rotation of the connector sleeve upon rotation of the shaft, and a second end pivotally connected to the handle body. The shaft body is movable between a first position wherein the shaft is at least partially disposed within the channel of the handle body and longitudinally aligned with the handle body, and a second position wherein the shaft body is perpendicular to the handle body.

  • Publication number: 20150272604
    Abstract: A surgical instrument is provided. The surgical instrument includes: a test end effector including a test jaw assembly having a pair of jaws configured to clamp about tissue and at least one sensor configured to measure at least one tissue property; and a handle assembly configured to couple to the treatment end effector. The handle assembly includes: a drive assembly; a motor operatively coupled to the drive assembly; and a controller operatively coupled to the motor, the controller configured to control operation of the motor to actuate the test end effector to measure the at least one tissue property and to determine, based on the at least one tissue property, at least one suitable treatment end effector.
