The second module comprises a second bridge connector portion that comprises a second outer housing and a second electrical connection element. The first module comprises a first bridge connector portion comprising a first outer housing and a first electrical connection element. The first outer housing is configured to engage the second outer housing during assembly of the modular energy system prior to the first electrical connection element engaging the second electrical connection element.

A modular surgical system for use in a surgical procedure is disclosed. The modular surgical system includes a control module including a power supply and surgical modules including a first surgical module and a second surgical module. The first surgical module is arranged in a stack configuration with the control module and the second surgical module. The power supply is configured to output power to the first surgical module and the second surgical module. A power backplane is configured to deliver the power to the first surgical module and the second surgical module through the first surgical module. A control circuit is configured to adaptively adjust power allocations to the first surgical module and the second surgical module.

An energy module connectable to a surgical instrument is disclosed. The energy module can include a circuit, which can include a first amplifier and a second amplifier coupled to a port of the energy module to which a surgical instrument is connectable. The first amplifier can be configured to generate a first drive signal at a first frequency range and the second amplifier can be configured to generate a second drive signal at a second frequency range. The circuit can be configured to control the amplifiers to deliver the first drive signal, the second drive signal, and/or a combination of the first and second drive signals to a surgical instrument connected to the port.

A modular surgical system is disclosed. The modular surgical system comprises a header module, a first surgical module, a second surgical module, and a module identification circuit. The second surgical module is arrangeable in a stack configuration with the header module and the first surgical module. The module identification circuit is configured to cause a pre-determined current to be transmitted to the first surgical module through the second surgical module in the stack configuration, detect a first voltage indicative of a first position of the first surgical module in the stack configuration, and detect a second voltage indicative of a second position of the second surgical module in the stack configuration. The second voltage is different than the first voltage.

A modular surgical system for use in a surgical procedure is disclosed. The modular surgical system includes a header module, a first surgical module, a second surgical module, a first backplane connector configured to detachably connect the header module to the first surgical module, and a second backplane connector configured to detachably connect the first surgical module to the second surgical module. The first surgical module is arrangeable in a stack configuration with the header module and the second surgical module. The first backplane connector is configured to yield a first bit pattern identifying the first surgical module in the stack configuration. The second backplane connector is configured to yield a second bit pattern identifying the second surgical module in the stack configuration. The first bit pattern is different than the second bit pattern.

A modular energy system including a header module and a module. The header module includes a display screen for displaying a user interface. The header module is configured to receive data, including safety critical data, from the module, control the display screen to cause the UI to display UI content based on the received data, the UI content including safety critical UI content based on the safety critical data, and transmit the displayed safety critical UI content to the module for verification thereby. The module is configured to confirm whether the transmitted safety critical data coincides with the displayed safety critical UI content. In the event that it is determined that they do not coincide, the header module and/or the module can be configured to stop the function(s) of the module, display an alert on the display screen, and take various other actions.

A valve sizer for determining an appropriate replacement valve size when performing a heart valve replacement procedure is provided. In one version the valve sizer has a hollow shaft with proximal and distal ends. A movable sizing element couples to the distal end of the shaft and is radially expandable between first, contracted and second, expanded positions. An actuator assembly on a handle includes an actuator coupled to a clutch member via a ball-spring-detent clutch. A rod extends through the shaft and maintains a fixed distance between the handle and a distal hub in the sizing element. Movement of the actuator causes axial movement of the shaft, thereby causing radial expansion of sizing petals relative to the hub. The clutch slips when a predetermined reaction force from the surrounding valve annulus is met by the petals.

A method comprising capturing a pose of a surgical tool at a surgical site of a patient. The method includes determining a range of movement of the surgical tool at the surgical site, in response to the captured pose. The method includes displaying a representation of the determined range of movement onto an image associated with the surgical site. The method includes providing one or more instructions to limit a movement of a robotic device according to the determined range of movement.

Disclosed are devices and methods for creating a bore in bone. The devices and methods described involve driving a rotating bit in an axial direction such that both rotation and linear movement are controlled and measurable. The instrument is useful for a surgeon to control and simultaneously measure the travel of the tool into the bone and prevent injury to surrounding structures.

An instrument for holding and torque control tightening of a threaded implant device with an extender, the instrument including a frame forming a gripping handle and a holder, an elastic device that is arranged at the frame to provide a predefined elasticity to the frame, and a torque measurement device arranged on the frame, wherein the holder is configured to (i) removably hold the threaded implant device and to (ii) hold the extender for tightening the threaded implant device to an object after the threaded implant device has been removed from the holder, and the torque measurement device is configured to measure a torque applied to the threaded implant device via the extender by a deformation of the frame.
