Abstract: A forceps includes a drive assembly and an end effector assembly having first and second jaw members movable between a spaced-apart position, a first approximated position, and a second approximated position. The drive assembly includes a drive housing and a drive bar. The proximal end of the drive bar is coupled to the drive housing, while the distal end of the drive bar is coupled to at least one of the jaw members. The drive housing and the drive bar are selectively movable in conjunction with one another between a first position and a second position to move the jaw members between the spaced-apart position and the first approximated position. The drive assembly is selectively activatable to move the drive bar independent of the drive housing from the second position to a third position to move the jaw members from the first approximated position to the second approximated position.

Abstract: A forceps includes an end effector assembly having a stop and a plurality of overmold teeth within at least one jaw member. One (or both) of the jaw members is moveable relative to the other between a spaced-apart position and an approximated position for grasping tissue therebetween. One (or both) of the jaw members includes a stop molded within an insulative housing, and an insulator plate with the overmold teeth formed from plastic. The overmold teeth extend through openings within a sealing plate and protrude past the tissue sealing surface of the sealing plate. The stop primarily controls the gap distance between opposing jaw members by bearing most of an applied load and the overmold teeth assist in controlling the gap distance by bearing the remaining applied load.

Abstract: A vessel sealing instrument includes a housing having a shaft extending from a distal end thereof, the distal end including an end effector assembly having a pair of opposing jaw members operably coupled thereto. One or both of the jaw members is moveable between open and closed positions for clamping tissue with a closure pressure. One or both of the jaw members connects to a generator that provides energy thereto in accordance with a sealing algorithm upon activation thereof. An anti-backdrive mechanism is coupled to the end effector assembly and includes a drive shaft coupled at one end to a solenoid and another end that engages one of the jaw members upon extension thereof to provide additional closure pressure between the jaw members. The drive shaft is extendible by the solenoid to extend the drive shaft in response to tissue expansion during sealing based on the sealing algorithm.

Abstract: A surgical system includes at least one audio sensor configured to sense audio during a surgical procedure and to output audio data based on the sensed audio. The surgical system further includes a computing device operably coupled to the at least one audio sensor and configured to receive the output audio data from the at least one audio sensor. The computing device includes a processor and memory storing instructions that, when executed by the processor, cause the processor to determine at least one of a cause or a location of a sound based at least on the output audio data and to output an indication of the at least one of the cause or location of the sound.

Abstract: An electrosurgical device includes jaw members, a thermal cutting element coupled to one of the jaw members. When the jaw members are in an approximated position, power is delivered to the thermal cutting element to maintain the temperature of the thermal cutting element at an operating temperature for cutting sealed tissue grasped between the jaw members. When the jaw members are in the spaced apart position, power is delivered to the thermal cutting element to maintain the temperature of the thermal cutting element at a standby setpoint temperature. In response to a determination of contact between tissue and the thermal cutting element when the jaw members are in the spaced apart position, power is delivered to the thermal cutting element to increase the temperature of the thermal cutting element from the standby setpoint temperature to a cutting setpoint temperature for dissecting tissue.

Abstract: A surgical instrument is provided and includes a housing having a shaft. An end effector assembly is operatively connected to a distal end of the shaft and has a pair of first and second jaw members that are movable relative to one another. A drive assembly operably couples to a handle assembly associated with the housing and is configured to impart movement of a respective jaw member when the handle assembly is actuated. A spring component operably associated with each of the jaw members is configured to provide a sealing force at the jaw members.

Abstract: A surgical instrument includes a housing that supports an elongated shaft. A selectively movable drive rod extends through the elongated shaft and carries a cam pin in a longitudinal direction. An end effector for surgically treating tissue is supported by the elongated shaft and includes upper and lower jaw members pivotally coupled to one another about a pivot axis. The upper jaw member includes a first pair of laterally spaced flanges, and the lower jaw member includes a second pair of laterally spaced flanges defining a camming slot for engaging the cam pin. The flanges are arranged in an offset configuration where one flange of the upper jaw member is positioned on a laterally exterior side of a corresponding flange of the lower jaw member, and the other flange of the upper jaw member is positioned on a laterally interior side of the other flange of the lower jaw member.

Abstract: An enhanced haptic feedback system for medical diagnostics includes a laparoscope configured to be inserted into a body cavity to view tissue and obtain an image of the viewed tissue. An imaging device is configured to acquire physiological data about tissue, process the acquired physiological data, and output the processed data to a graphical user haptic interface (GUHI) capable of generating tangible sensations utilizing one or more haptic interfaces. The GUHI is configured to combine the image received from the laparoscope and the processed physiological data received from the imaging device to provide tangible sensations on both a front screen of the GUHI and a rear screen of the GUHI allowing a surgeon the sensation of feeling for abnormal tissue conditions between the surgeon's hands.

Abstract: A surgical instrument includes a housing, a shaft extending distally from the housing, an end effector disposed at a distal end of the shaft, an actuator operably coupled to the housing, an actuation assembly, and a sensor module. The actuation assembly extends through the housing and the shaft and includes a distal end operably coupled to the end effector or a component associated therewith, a proximal end operably coupled to the actuator, and a spring. Actuation of the actuator manipulates the end effector or deploys the component relative thereto. The sensor module is disposed within the housing and configured to sense a property of the spring indicative of an amount the spring has been compressed. The sensor module is further configured, based upon the sensed property, to determine a condition of the end effector or the relative position of the component.
