Abstract: A knee brace includes a support module including a first body, a second body, and a hinge movably coupling the first body to the second body. The hinge includes a pin and a receptacle in the first and second bodies. The pin defines a plurality of teeth thereon and the receptacle defines a plurality of teeth therein. The plurality of teeth on the pin are configured to engage with the plurality of teeth in the receptacle such that the pin is rotatable and translatable within the receptacle. The knee brace also includes a fastener configured to releasably attach the knee brace to a leg. The first and second bodies couples with a first portion of the leg and with a second portion of the leg via the fastener. The first and second portions of the leg are separated by a knee joint of the leg.

Abstract: A knee brace includes a support module including a first body, a second body, and a hinge movably coupling the first body to the second body. The includes a pin on one of the first and second bodies, and a receptacle on the other of the first and second bodies. The receptacle is configured to receive the pin therein, such that the pin is rotatable and translatable within the receptacle.

Abstract: An assembly for performing intranasal endoscopy on a patient includes a mouth gag defining a central cavity, where the mouth gag is configured to be at least partly received in an oral cavity of the patient, and an outer cannula defining a central lumen, where the outer cannula is configured to be introduced through the central cavity of the mouth gag. The assembly also includes an endoscope extending through the central lumen of the outer cannula and configured to be advanced into a nasal cavity of the patient.

Abstract: A semi-rigid endoscope may include a shaft that is elongate along a longitudinal direction. The shaft including a shaft body that defines: proximal rigid portion and a flexible tip that is distal to the proximal rigid portion. The flexible tip moves along a lateral direction that is perpendicular to the longitudinal direction. The flexible tip moves along a transverse direction that is perpendicular to both the longitudinal and lateral directions. The endoscope may also include at least one conduit that extends longitudinally along an internal portion of the shaft body. The internal portion may be substantially enclosed, such that the at least one conduit transfers irrigant fluid to and from the flexible tip. The endoscope may also include a baffle that directs irrigant fluid at the flexible tip and an image sensor coupled to the flexible tip.
