Surgical lighting must balance various needs of a user: the light must be bright, but not too thermally hot; directed at a target, but not shining elsewhere; be robust, yet compact. Often much of these myriad needs must be accomplished by ever small illumination elements placed into devices requiring ever lower profiles. However, current surgical illumination options require the use of bulky lighting elements if the desire target is to be illuminated or, conversely, use weaker lighting elements for sleeker designs.

The present disclosure relates to a lighting arrangement, which comprises at least one light source, with at least one camera and a control system, wherein the colour and/or colour temperature of the light source is variable and the camera records images of a region illuminated by the light source. According to the disclosure, the control system controls the lighting arrangement such that the light source illuminates the illuminated region successively with light of a different colour and/or colour temperature, wherein the control system separately evaluates and/or outputs a first image recorded in a first colour and/or colour temperature of the lighting.

The present technology relates to a surgery system, a control method, a surgical apparatus, and a program that allow easy updating of a function of a medical apparatus. A configuration includes an information processor, and a surgical apparatus. The information processor includes a storage section storing an application, and a transmission section transmitting, in response to a request from the surgical apparatus, the application stored in the storage section. The surgical apparatus includes a reception section receiving the application transmitted by the transmission section, and an execution section executing the application received by the reception section.

Control systems and methods for delivery of energy that may include control algorithms that prevent energy delivery if a fault is detected and may provide energy delivery to produce a substantially constant temperature at a delivery site. In some embodiments, the control systems and methods may be used to control the delivery of energy, such as radiofrequency energy, to body tissue, such as lung tissue.

Certain embodiments may relate to apparatuses and methods for performing surgical procedures. For example, a method may comprise initiating detection and tracking of at least one surgical instrument (including associated surgical material) within a surgical area. The method may further comprise performing a surgical procedure with the at least one surgical instrument and material and ending detection and tracking of the at least one surgical instrument and material within the surgical area. The method may further comprise displaying at least one indication of location status of the at least one surgical instrument.

The present disclosure relates to systems, devices, and methods for augmenting a two-dimensional image with three-dimensional pose information of instruments shown in the two-dimensional image.

A user-wearable fluorescence based visualization system comprising a multi-light lamp assembly that provides for the selected output of light using multiple light emitting sources, wherein the outputted light may be tailored to generate response wavelength by the interaction of the emitted light and a tissue illuminated by the emitted light, through the process of fluorescence, and a viewing system that allows a practitioner view the fluorescent light generated by the tissue, and distinguish between healthy and diseased tissues.

Example embodiments relate to robotic arm assemblies. The robotic arm assembly includes forearm and upper arm segments. Upper arm segment includes distal motor. Robotic arm assembly includes elbow coupling joint assembly connecting distal end of upper arm segment to proximal end of forearm segment via a serial arrangement of proximal and distal elbow joints. Proximal elbow joint is located between upper arm segment and distal elbow joint. Distal elbow joint is located between proximal elbow joint and forearm segment. Proximal elbow joint forms proximal main elbow axis. Distal elbow joint forms distal main elbow axis. Elbow coupling joint assembly includes distal elbow joint subassembly connected to forearm segment. Elbow coupling joint assembly includes proximal elbow joint subassembly connecting upper arm segment to distal elbow joint subassembly. Proximal elbow joint subassembly is configured to be driven to rotate forearm segment relative to proximal main elbow axis.

A hydrodissector for hydrodissecting a vascular target, the hydrodissector comprising: a handle; a shaft extending from the handle at an angle and including a tip at a distal end thereof; at least one port provided at the tip and configured to be coupled to a fluid supply and to eject fluid from the at least one port into the space between the vascular target and surrounding tissues to dissect the vascular target from the surrounding tissues, the at least one port being sized to provide sufficient pressure and velocity to dissect the vascular target from the surrounding tissues, wherein the length of the shaft is configured for insertion into an incision to atraumatically hydrodissect the vascular target from the surrounding tissues, and wherein the shaft is configured to releasably couple with one or more hook-shaped attachments configured to lift the vascular target after the vascular target is dissected from the surrounding tissues.

A tissue dissector includes a handle assembly including an actuator, a head portion including a blade member defining an aperture configured to receive tissue therethrough, and a lighting assembly configured to provide lighting to the aperture of the blade member. The blade member is operatively coupled with the actuator for rotation about the aperture.
