A footswitch for a medical instrument, with a housing, and with an elastically deformable suction cup arranged in the housing, where a negative pressure is generated in the suction cup by means of an evacuation device in order to secure the housing to a floor surface. In order to create a footswitch which is suitable for a medical instrument and which, while having a simple design and being easy to handle, ensures that the footswitch is secured in a fixed position on a floor surface. The suction cup is elastically extensible via the evacuation device in order to generate the negative pressure by enlargement of the volume enclosed by the suction cup.

An endoscope bending operation mechanism includes: an operation lever with one end being rotatably held; a frame configured to rotate with the operation lever; a fixing member rotatably supporting the frame; a rotation shaft coupled with an end portion of one of the frame and the fixing member; a bearing portion provided on the other of the frame and the fixing member and having a hole rotatably holding the rotation shaft; and a position defining portion configured to abut a part of the other of the frame and the fixing member to define a position of the rotation shaft. The position of the rotation shaft is adjustable, and by adjusting the position of the rotation shaft, a clearance between the bearing portion and the position defining portion in a direction along a central axis is adjusted.

A rotary encoder includes a substrate, two or more switches disposed on the substrate, a mechanical wave generator, and a controller. The mechanical wave generator is disposed proximate to the substrate. The substrate and the mechanical wave generator are adapted to rotate relative to each other about a central axis. The mechanical wave generator has a profile shape that repeats circumferentially about the central axis. The profile shape has ridges and valleys that engage the two or more switches to activate and deactivate the two or more switches as the substrate and the mechanical wave generator rotate relative to each other. The controller is electrically coupled to the two or more switches to track activations of the two or more switches and digitally encode a rotational position of the substrate relative to the wave generator based upon the activations.

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.

A surgical instrument is disclosed. The surgical instrument includes a body, a shaft and a control circuit. The control circuit includes at least one sensing device and is to determine a presence of another surgical instrument proximate to the surgical instrument within an environment of a surgical procedure.

A surgical instrument is disclosed comprising a housing and a control circuit mounted to and/or embedded in the housing.

A surgical instrument is disclosed comprising an actuator and circuitry mounted on and/or embedded in the actuator.

A surgical instrument is disclosed comprising a control system and a strain gage circuit. The operation of the control system is modifiable by an input from the strain gage circuit.

A surgical hub is disclosed. The surgical hub includes a processor and a memory coupled to the processor. The memory stores instructions executable by the processor to receive image data from an image sensor, generate a first image based on the image data, display the first image on a surgical hub display coupled to the processor, receive a signal from a non-contact sensor, the signal indicative of a position of a surgical device, generate a second image based on the signal indicative of the position of the surgical device, and display the second image on the surgical hub display coupled to the processor.

A surgical instrument is disclosed. The surgical instrument includes a shaft, a sensing array and a fluid detection circuit. The sensing array is positioned within the shaft. The fluid detection circuit is electrically coupled to the sensing array, and is configured to determine when a fluid originating from an environment external to the shaft is present within the shaft.
