An apparatus and method of manufacture includes a helical wire coil and a core wire. The core wire has a first wire portion and a second wire portion. The first wire portion of the core wire extends through the helical wire coil. The second wire portion of the core wire is intertwined with the first helical wire coil to fixedly secure the core wire relative to the first helical wire coil. The core wire is formed from a first material that is non-extensible. The core wire is fixedly secured relative to a distal portion of the helical wire coil such that the core wire inhibits longitudinal elongation of the helical wire coil along a longitudinal coil axis.

Robotic systems can be capable of commanding bar translation. A robotic system can include a robotically controlled first kinematic chain, a robotically controlled second kinematic chain that is movably coupled to the first kinematic chain, and a controller that is communicably coupled to the first kinematic chain and the second kinematic chain. The robotic system can be figured to obtain data corresponding to the first kinematic chain, and control movement of the second kinematic chain in accordance with the data corresponding to the first kinematic chain.

Certain aspects relate to systems and techniques for a patient platform system that includes a table and one or more kinematic chains that are coupled to the table. The table includes a rigid base and a table top that is movable relative to the rigid base. One or more processors initiate first movement of the table top relative to the rigid base in accordance with a user request, and move the one or more kinematic chains relative to the rigid base in coordination with the first movement of the table top such that one or more preset conditions are maintained during the first movement of the table top.

A robotic system can include a surgical instrument with a wrist that allows N degrees of freedom of movement. The N degrees of freedom can be controlled by N+1 cable segments. The wrist can include a first set pulleys configured to rotate about a first axis and a second set of pulleys configured to rotate about a second axis. The wrist can further comprise one or more pulleys configured to engage two of the cable segments, wherein at least one of the pulleys is shared by a first cable segment and a second cable segment. The first cable segment and the second cable segment that share the pulley can be independent from one another. In some circumstances, the surgical instrument can be actuated N+1 degrees of movement by advancing or retracting at least two of N+1 cable segments.

Methods, apparatuses, and systems for autonomous surgical robot evolution and handoff for manual operation are disclosed. A robotic surgical system performs surgery and is controlled jointly by an artificial intelligence (AI) and a surgeon. The surgeon can perform the entire surgery or can alternatively allow the AI to control the surgical robot to perform a part of or the entirety of the surgery. The AI is trained using data from previous surgeries, can provide indication to the surgeon when it has been sufficient trained to take over parts of a surgery, and can prompt the surgeon when there is insufficient training data for the AI to continue. Alternatively, a supervising surgeon can manually take back control of the surgical robot from the AI.

A fastener cartridge for use with a surgical instrument. The cartridge may include a cartridge body that has a series of staple pockets therein. A driver is movably supported in each staple pocket and is configured to operably support at least one surgical staple thereon. In one arrangement, at least some of the drivers may be formed with one or more laterally extending features that are configured to be received in correspondingly-shaped grooves in the cartridge body to provide lateral support to the driver as it is operably moved within the staple pocket. In other arrangements, at least one inwardly-extending features is formed in the inner wall surface of the pocket and is configured to be movably supported within correspondingly-shaped groove in the driver.

A medical lighting device, a system for fluorescence image guided surgery and a method to manufacture a medical lighting device are provided. The medical lighting device includes a device body and light guiding optics. The light guiding optics comprise optical fibers and a first ring-shaped mirror encircling the device body. A segment of each optical fiber passes through the first ring-shaped mirror while being guided towards the distal end. After passing through the first ring-shaped mirror, a light guiding element redirects one or more of excitation light and white light ack towards the first ring-shaped mirror. The first ring-shaped mirror reflects the one or more of the emitted excitation light and the white light towards the area to be illuminated by the one or more of the excitation light and the white light.

In some embodiments, a microsurgical instrument includes a trocar having a rigid, hollow shaft formed with a lumen extending from a proximal end to a distal end of the shaft. The distal end of the shaft may be shaped for tissue penetration. The instrument may further include a composite microcannula slidably engaged with the trocar in the lumen. The microcannula includes a light guide and a flexible hollow tube having an outer diameter less than an inner diameter of the lumen in the trocar. Other embodiments include placing the microcannula in the lumen of the trocar, illuminating the end of the trocar by illuminating the end of the microcannula, advancing the trocar from a selected entry point on an eye into a selected structure in the eye, and extending the illuminated end of the microcannula from the trocar into the selected structure.

An ultrasound catheter with fluid delivery lumens, fluid evacuation lumens and a light source is used for the treatment of intracerebral hemorrhages. After the catheter is inserted into a blood clot in the brain, a lytic drug can be delivered to the blood clot via the fluid delivery lumens while applying ultrasonic energy to the treatment site. As the blood clot is dissolved, the liquefied blood clot can be removed by evacuation through the fluid evacuation lumens.

The present disclosure provides an adjustable endoscopic surgical device for illuminating a tissue surface with diffuse and oblique light. In some embodiments, light emanates from the sides of an optical fiber, which is optionally formed at least in part into a loop shape.
