A medical observation system includes: a plurality of types of sensor units that measure information regarding an internal environment; an acquisition unit (131) that acquires individual sensor values of the plurality of types of sensor units; a comparison unit (132) that compares the individual sensor values of the plurality of types of sensor units acquired by the acquisition unit (131); and a determination unit (134) that determines a sensor unit to be used for observing the internal environment among the plurality of types of sensor units based on a comparison result obtained by the comparison unit (132).

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

Disclosed are various examples and embodiments of systems, devices, components and methods configured to estimate the action potential wave propagation in a patient's heart, and subsequently to detect at least one location or type of at least one source of, or rotational phenomenon associated with, at least one cardiac rhythm disorder using intracardiac electrodes and a modified multi-frame Horn-Schunck algorithm to generate a map corresponding to a spatial map, the map being configured to reveal on a monitor or display to a user the at least one location of the at least one source of the at least one cardiac rhythm disorder.

A measuring device and methods of use for measuring a section of a bowel of a patient. The measuring device includes a tubular section having a longitudinal axis and at least one wing normally projecting outward transverse to the longitudinal axis. The tubular section is configured for mounting on a conventional or robotic laparoscopic grasper adjacent the grasper's movable jaws. The at least one wing is are pivotable to a closed position so that grasper with the measuring device mounted thereon can be inserted through a conventional trocar, whereupon the at least one wing projects outward transversely to the longitudinal axis. The at least one wing is of a predetermined length to serve as a measurement tool enabling a surgeon to measure off a desired length of the bowel.

An exemplary hand-held, power operated rotary knife dermatome comprises a blade housing assembly and a depth gauge assembly. The blade housing assembly includes an annular blade housing and a blade lock ring for rotatably supporting an annular rotary knife blade. The annular blade housing includes a shield extending radially inwardly from a blade receiving body and including an inner wall defining a tissue directing surface, the tissue directing surface including a first tissue guide surface extending upwardly from a lower end of the shield, the first tissue guide surface extending substantially parallel to the blade housing axially extending center line. The blade receiving body includes an annular blade channel extending axially upwardly from a lower surface of the blade receiving body, a bearing surface axially spaced from a lower surface of the blade receiving body, and a threaded portion formed on the outer surface of the annular blade housing.

A stretch-measurement probe includes an elongate outer sleeve, expansion feature associated with a distal portion of the outer sleeve, and an elongate inner rod disposed at least partially within the outer sleeve. The expansion feature is configured to allow a longitudinal distance between a proximal end of the outer sleeve and the distal end of the outer sleeve to be varied.

A gap gauge is disclosed for facilitating an arthroplasty procedure on a first bone and a second bone of a patient. The gap gauge may include a first plate positionable in contact with the first bone, a second plate positionable in contact with the second bone. The second plate may be displaced from the first plate by a displacement. The gap gauge may further include a balance indicator configured to indicate a balance status between the first plate and the second plate and a pin guide. The pin guide is configured to couple to one of the first plate and second plate and includes a pin hole that is configured to guide a pin for insertion into the second bone. The pin can be used to couple a cutting guide to the second bone to resect the second bone to adjust the balance status.

A gap gauge is disclosed for facilitating an arthroplasty procedure on a first bone and a second bone of a patient. The gap gauge may include a first plate positionable in contact with the first bone, a second plate positionable in contact with the second bone. The second plate may be displaced from the first plate by a displacement. The gap gauge may further include a separator connected to the first plate and the second plate, a separation indicator coupled to the separator and configured to indicate the displacement, and a balance indicator connected to at least one of the first plate and the second plate. The balance indicator may indicate a balance status between the first plate and the second plate. The separator can be actuated to adjust the displacement.

A freely-connectable three-strut parallel orthopedic external fixator including two fixation rings and three struts, connecting holes are circumferentially and uniformly distributed on the ring surfaces of each fixation ring, each strut is provided with two driving translational pairs, a revolute pair and a spherical pair. Two fixation rings are respectively fixedly connected with the bone segments of the fracture site by using medical metal bone pins; adjusting the driving translational pairs of the six struts can achieve six DoF relative movement of the two fixation rings, thereby achieving fracture reduction. The external fixator of the present invention realizes free connection between the two fixation rings, which facilitates fixator installment; number of struts is less than the existing external fixators.

A system and apparatus for increasing the amplitude of accommodation and/or changing the refractive power and/or enabling the removal of the clear or cataractous lens material of a natural crystalline lens is provided. Generally, the system comprises a laser, optics for delivering the laser beam and a control system for delivering the laser beam to the lens in a particular pattern. There is further provided a range determining system for determining the shape and position of the lens with respect to the laser. There is yet further provided a method and system for delivering a laser beam in the lens of the eye in a predetermined shot pattern.
