  • Patent number: 11992208
    Abstract: A stapling system including a housing that has a first rotatable disk configured to transmit a first operative motion and a second rotatable disk configured to transmit a second operative motion is disclosed herein. The second rotatable disk is operable independently of said first rotatable disk. The stapling system further includes an end effector, an elongate rigid shaft, and a drive system. The drive system is responsive to the first operative motion from the first rotatable disk to perform a closing motion of the end effector and responsive to the second operative motion from the second rotatable disk to perform a firing stroke. A control system is configured to assure that the closing motion and the firing stroke are separate and distinct, wherein the control system prevents the firing stroke from occurring prior to the completion of the closing motion.

  • Publication number: 20240122598
    Abstract: In one general aspect, various embodiments of the present invention can include a motorized surgical cutting and fastening instrument having a drive shaft, a motor selectively engageable with the drive shaft, and a manual return mechanism configured to operably disengage the motor from the drive shaft and retract the drive shaft. In at least one embodiment, a surgeon, or other operator of the surgical instrument, can utilize the manual return mechanism to retract the drive shaft after it has been advanced, especially when the motor, or a power source supplying the motor, has failed or is otherwise unable to provide a force sufficient to retract the drive shaft.

  • Patent number: 11944366
    Abstract: An end-effector is disclosed including an ultrasonic blade configured to acoustically couple to an ultrasonic transducer and electrically couple to a pole of an electrical generator and a clamp arm including a clamp jaw and a cantilever electrode fixed to the clamp jaw. The cantilever electrode is configured to electrically couple to an opposite pole of the electrical generator. The clamp arm may include an I-beam shaped clamp arm pad and the cantilever electrode is disposed between the I-beam. The clamp jaw, the cantilever electrode, and the clamp arm pad may define recesses along a length coinciding with the ultrasonic blade. The clamp arm pad may be fixed to the clamp jaw and disposed between the clamp jaw and the cantilever electrode and may extend beyond the surface of the cantilever electrode. The clamp arm may include a stationary gap setting pad and movable floating gap setting pads.

  • Patent number: 11944299
    Abstract: A surgical instrument. The surgical instrument has a force delivery system which communicates a changing force to a user of the surgical instrument when a limit of a surgical function is reached. A sensor senses position of a moving element to communicate a signal to the force delivery system. In various embodiments, the system generates a vibratory force to signal the user.

  • Patent number: 11931034
    Abstract: A surgical instrument includes an anvil and an elongate channel. The elongate channel includes a plurality of first electrical contacts and a plurality of electrical connectors comprising a plurality of second electrical contacts, wherein the electrical connectors are spring-biased such that a gap is maintained between the first electrical contacts and the second electrical contacts. The surgical instrument further includes a staple cartridge releasably attachable to the elongate channel, wherein the staple cartridge has a cartridge body comprising a plurality of staple cavities, a plurality of staples deployable from the staple cavities into the tissue, and a plurality of third electrical contacts, wherein the attachment of the staple cartridge to the elongate channel moves the electrical connectors causing the second electrical contacts to bridge the gap and become electrically coupled to the first electrical contacts.

  • Patent number: 11925350
    Abstract: A method of operating a surgical stapling device comprising a lockout for preventing the surgical stapling device from operating. The method comprises contacting a first authentication key protruding from a surgical staple cartridge in actuation contact with the lockout in the surgical stapling device to move the lockout into an intermediate position, contacting a second authentication key protruding from the surgical stapling cartridge distal to the first authentication key into other actuation contact with the lockout in the surgical stapling device to move the lockout from the intermediate position into an unlocked position, and operating the surgical stapling device.

  • Patent number: 11918208
    Abstract: A surgical instrument including an end effector that has a selectively reciprocatable implement movably supported therein. The implement is selectively advanceable in a distal direction upon application of a rotary actuation motion thereto and retractable in a proximal direction upon application of a rotary retraction motion thereto. An elongate shaft assembly is coupled to the end effector and is configured to transmit the rotary actuation motion and rotary retraction motion to the reciprocatable implement from a robotic system that is configured to generate the rotary actuation motion and said rotary retraction motion.

  • Patent number: 6651486
    Abstract: A pressure testing device comprising a connector adapted to engage a gas line containing a gas supply under pressure is provided. The pressure testing device includes a measuring device and a compressible pump. The measuring device operably communicates with the connector and is responsive to variations in pressure of the gas supply. The compressible pump has an input port and an exhaust port. The input port is adapted to receive ambient gases and the exhaust port is adapted to communicate with the measuring device for delivering ambient gas pressure to the measuring device.

  • Patent number: 5253362
    Abstract: Annotations to data objects are stored in the object instance and may be stored in an annotation file or a reference may be store in a reference file. Once annotated, a cell displaying the data object will provide a notation indicating that the data object has an annotation associated therewith. Retrieval of annotations which are not stored in an annotation file or reference file occurs through a search of the object instances. Retrieval of annotations having a reference in a reference file occurs through use of the reference to access the object instances. Retrieval of annotations in an annotation file occurs through retrieval of the annotation file. Once retrieved, the annotations may be in a final form, such as the nursing progress notes, or may be on a scratch pad to allow the user to electronically transfer annotations from a scratch pad to a permanent record.

  • Patent number: 5208907
    Abstract: Input to the system is buffered by the forms manager to determine access to the tile/region and to check entered data. The tile/region will retain various information such as data entered, user, time, changes, etc. To display a form, the forms manager obtains a list of objects to be displayed. This list of objects is then edited to remove objects which are not utilized and to place the remaining objects in a prioritized order. The forms manager then generates the display.

  • Patent number: 5108107
    Abstract: A portable Golf Swing Practice Device designed to train the Golfer in how to develop a full swing. This device responds to a full swing by returning the tethered golf ball to the original general tee off area or beyond when struck with the golf club in the correct fashioned, a full swing. The tethering is accomplished by the use of ground attachment, a dacron line and a nylon stretch cord attached to a golf ball, assembled in such a fashion as to allow consistent repeated use. By seeing these results the Golfer can develop a full swing which in turn will develop a better Golfer.
