Appl. No.:

17/878406

International Classification:

A61B 17/062
A61B 17/04

Abstract:

Needle drivers and methods of the present disclosure are generally directed at intracorporeal suture tying using a winding technique. For example, a needle driver may include an elongate shaft having a magnet section between a proximal section and a distal section. A clamp coupled to the distal section may grasp a first end portion of a suture. A needle coupled to a second end portion of the suture may be magnetically secured to the magnet section, and the magnet section may then be rotated to form a loop in the suture. Forming a knot in the suture may include moving the loop over the first end portion of the suture grasped in the clamp. As compared to other intracorporeal suture tying techniques, intracorporeal knot tying carried out using the needle drivers and methods of the present disclosure may reduce the time and complexity associated with laparoscopic procedures.

International Classification:

A61G 7/00
A61G 7/05

Abstract:

A proning device includes a conformable structure that adapts to the shape of a subject, surrounded by a shell that imparts a substantially elliptical cross-sectional shape to an exterior of the device to facilitate rotation of the subject within the device when the device is wrapped around the subject. A low-friction interface may also be provided to further facilitate rotation of the subject. The device advantageously reduces staffing needs for proning a subject while facilitating extended proning and periodic re-orientation of the subject. Also disclosed herein are methods for making and using such a proning device.

International Classification:

A61B 18/08

Abstract:

An electrocautery device with a retractable suction tube is described. The electrocautery device includes a suction tube assembly that can move between an extended or retracted position using vacuum force generated by a suction source. In some embodiments, the suction tube assembly automatically locks into the extended position when extended such that axial force cannot cause the suction tube assembly to retract. The device may be suitable for use in laparoscopic procedures. The suction tube may be coaxially aligned with the electrocautery tip.
