Cable tensioning in a robotic surgical system

A cable tensioning system of a surgical system comprises a base, an arm, and a moveable idler pulley rotatably coupled to a first end of the arm and positioned between a first pulley system and a second pulley system. A closed loop cable drive extends between the first pulley system and the second pulley system, and the closed loop cable drive passes over the moveable idler pulley. The cable tensioning system also comprises a translation mechanism slidably coupling a second end of the arm to the base. The translation mechanism is configured to move the arm relative to the base along a linear path between a first position and a second position such that the moveable idler pulley is moved away from at least one of the first pulley system or the second pulley system to control a tension in the closed loop cable drive.

Catheter insertion-tray systems and methods thereof

A catheterization package including a catheterization tray and contents for a catheterization procedure. The catheterization tray can include a structural configuration for maintaining a sterile field about a patient throughout the catheterization procedure, the sterile field including at least a portion of the tray. The structural configuration of the tray can provide a sterile side of the tray designated for a first person performing sterile steps of the catheterization procedure in the sterile field. The structural configuration of the tray can also provide a non-sterile side of the tray designated for either the first person or a second person performing non-sterile steps of the catheterization procedure outside the sterile field. The contents for the catheterization procedure can include a perineal care kit, two or more pairs of gloves, and a drainage system including a catheter.

A catheterization tray includes a sterile side configured to enable a user to carry out sterile steps of a catheterization procedure in a sterile field and a set of sterile items positioned in the sterile side of the catheterization tray. The catheterization tray further includes a non-sterile side configured to enable a user to carry out non-sterile steps of the catheterization procedure outside of the sterile field and a set of non-sterile items positioned in the non-sterile side of the catheterization tray. The catheterization tray further includes a partition extending between the sterile side and the non-sterile side from a first side wall of the catheterization tray to a second side wall of the catheterization tray to maintain sterility of the sterile side of the catheterization tray.

Flexible face mask for various dental and medical uses
12471645 · 2025-11-18 · ·

A flexible mask substrate (MS) with a rigid front plate (FP) which may be a viewing window (VW) causing the mask substrate to extend forward from a patient's face, forming a chamber in front of the patient's mouth. Instrument ports (IP) allow instruments to be introduced through the mask into the patient's oral or nasal cavity to perform dental or medical procedures. An elastic band (CE) on the mask substrate to conform the mask to contours of the patient's face. A malleable metal strip (MM) for conforming the mask to the patient's nose. Methods of fabricating the mask. The mask, and variations thereof, may be used to perform various treatments, including non-oral procedures. Using a nebulizer in conjunction with the mask, wherein the nebulizer is supported independently of the mask by a headband or eyeglasses worn by the patient.

Shape-sensing systems and methods for medical devices

Shape-sensing systems and methods for catheters. The shape-sensing system can include a catheter, an optical interrogator, a console, and a display screen. The catheter can include an integrated optical-fiber stylet having fiber Bragg grating (FBG) sensors along at least a distal-end portion thereof. The optical interrogator can be configured to send input optical signals into the optical-fiber stylet and receive FBG sensor-reflected optical signals therefrom. The console can be configured to convert the reflected optical signals into plottable data for displaying plots thereof on the display screen. The plots can include a plot of curvature vs. time for each FBG sensor of a selection of the FBG sensors in the distal-end portion of the optical-fiber stylet for identifying a distinctive change in strain of the optical-fiber stylet as a tip of the catheter is advanced into a superior vena cava of a patient.
