  • SURGICAL ACCESS DEVICES AND METHODS PROVIDING SEAL MOVEMENT IN PREDEFINED MOVEMENT REGIONS
    Publication number: 20240081802
    Abstract: Various methods and devices are provided for allowing multiple surgical instruments to be inserted into sealing elements of a single surgical access device. The sealing elements can be movable along predefined pathways within the device to allow surgical instruments inserted through the sealing elements to be moved laterally, rotationally, angularly, and vertically relative to a central longitudinal axis of the device for ease of manipulation within a patient's body while maintaining insufflation.

  • Electrosurgical adaptation techniques of energy modality for combination electrosurgical instruments based on shorting or tissue impedance irregularity
    Patent number: 11918275
    Abstract: Disclosed is a method of adapting energy modality due to a short circuit or tissue type grasped in the jaws of an end effector of a surgical instrument. The method includes selecting an electrode in an array of segmented electrodes during a pre-energy activation cycle. The method includes applying a sub-therapeutic electrical signal to the selected electrode to differentiate between a shorted electrode and low impedance tissue grasped in the jaws of the end effector. The method includes determining the selected electrode is shorted based on a measured electrical parameter received by the control circuit after applying the sub-therapeutic electrical signal and blending monopolar and bipolar RF energy. The method includes determining that the selected electrode is shorted and switching output energy of the RF generator between monopolar and bipolar RF energy.

  • Sterile field interactive control displays
    Patent number: 11918302
    Abstract: An interactive control unit is disclosed. The interactive control unit includes an interactive touchscreen display, an interface configured to couple the control unit to a surgical hub, a processor, and a memory coupled to the processor. The memory stores instructions executable by the processor to receive input commands from the interactive touchscreen display located inside a sterile field and transmit the input commands to the surgical hub to control devices coupled to the surgical hub located outside the sterile field.
