The inner sleeve assembly is coaxially and rotatably received in the central passage of the outer sleeve assembly, and the burr has a plurality of metal cutting edges carried on a first side of the distal end of the inner sleeve assembly. The electrode is carried a second side of the distal end of the inner sleeve assembly.

SKIN TREATMENT TOOL APPLICATOR TIP
20230000523 · 2023-01-05 ·

The present invention is an applicator tip for a hand piece assembly used in dermal abrasion procedures, the applicator tip having a cap shape with a plurality of apertures that form ports communicating with a fluid supply line in the hand piece assembly and a vacuum source to remove the abrading fluid. The fluid is introduced onto the outer abrading surface of the applicator tip through a first central aperture and spreads out along the outer abrading surface when the applicator tip is placed against the patient's skin. Recesses in the outer abrading surface establish pathways for the abrading fluid to move along as the applicator tip is moved over the patient's skin. The fluid emitting from the central port is moved into one of four quadrants defined by recesses in the outer abrading surface, each quadrant serving as a fluid chamber that receives fluid from the central fluid supply port. Each sector shaped chamber includes within its border a C-shaped barrier with its opening facing a dividing sector wall. As the applicator tip forms a seal with the patient's skin, fluid is introduced through the supply port and through the entrance of the chamber, filling each chamber with working fluid as the working fluid flows to and around the C-shaped barrier. Disposed inside each C-shaped barrier is a respective vacuum port that removes the working fluid from each chamber. Fluid from each chamber is vacuumed through its vacuum port after having flowed around a maze-like path, navigating the C-shaped barrier and sector walls in a vortex flow pattern.

Surgical instrument with robotic and manual actuation features

A surgical instrument comprises a housing and a valve mounted in the housing. The valve is configured to control a flow of a fluid into or out of a surgical site in response to either a robotic actuation of the valve or a manual actuation of the valve. The valve comprises a valve shaft, a receiving member structurally coupled to the valve shaft, and a manual actuation component structurally coupled to the valve shaft and extending from the housing. The receiving member is configured to releasably couple to a driver of a robotic manipulator to receive the robotic actuation from the driver remotely controlled by a surgeon to adjust a state of the valve. The manual actuation component is configured to receive the manual actuation to adjust the state of the valve.

Devices, systems and methods for treating the skin

According to some embodiments, a method of treating a skin surface of a subject comprises heating a skin surface, abrading native skin tissue of a subject using a microdermabrasion device, wherein using the microdermabrasion device comprises moving the microdermabrasion device relative to the skin surface while simultaneously delivering at least one treatment fluid to the skin surface being treated and cooling the abraded skin surface.

Methods and apparatus for removing material from within a mammalian cavity using an insertable endoscopic instrument

An endoscope for removing tissue at a surgical site includes an elongated tubular body insertable within a mammalian cavity of a patient. An instrument channel extends between a first opening at a distal end and a second opening at a proximal end of the tubular body and is sized and configured to receive a surgical cutting assembly that includes an aspiration channel configured to remove material entering the endoscope via a distal end of the surgical cutting assembly. A torque generation component configured to generate torque is positioned within the distal end and configured to provide the generated torque to a coupling component. The coupling component is positioned at the distal end of the elongated tubular member and configured to actuate a cutting component of the surgical cutting assembly responsive to actuation of the torque generation component.

Method of hub communication with surgical instrument systems

A method for adjusting the operation of a surgical instrument using machine learning in a surgical suite is disclosed.
