A collapsible detection antenna to detect electromagnetic tags of surgical articles in an operating room includes an antenna assembly configured to detect the electromagnetic tags. The antenna assembly is configured to move between a deployed configuration and a collapsed configuration. In the deployed configuration, the antenna assembly forms an antenna loop configured to detect the electromagnetic tags. The antenna assembly has a greater detection range in the deployed configuration than in the collapsed configuration. The deployed configuration corresponds to a tuned shape of the antenna assembly sufficient to detect the electromagnetic tags in the deployed configuration.

A manifold for collecting a tissue sample with a medical waste collection assembly. A base portion of a housing is removably engaged with a manifold receiver to provide a suction path from an inlet fitting receiving a suction line. A tray may be removably positioned within an accessory sleeve. Locating features facilitate defining a gap between a base portion of the tray and a lower barrier of the accessory sleeve. The tray may include a control surface to move the manifold between a sealing configuration, and a bleed configuration in which a second suction path is provided through the gap and below the tray. A backflow prevention valve may be disposed within the suction path between the tray and a filter element. Methods for collecting the tissue sample are also disclosed.

A mill head for replaceable attachment to a base so as to collectively form a bone mill. The mill head includes shell with: a first opening in which bone stock is introduced into the head; and a second opening through which the bone chips are discharged. A cutting device is mounted in the shell to both rotate and move laterally. Attached to the cutting device are coupling features for engaging a drive spindle able to rotate the cutting device. Also attached to the housing is an alignment feature. The alignment feature engages a complementary alignment feature associated with the drive spindle so as a result of the engagement of the alignment features, the cutting device moves within the shell so that the cutting device coupling features are positioned to engage the drive spindle.

A collapsible detection antenna () to detect electromagnetic tags () of surgical articles () in an operating room () includes an antenna assembly () configured to detect the electromagnetic tags (). The antenna assembly () is configured to move between a deployed configuration and a collapsed configuration. In the deployed configuration, the antenna assembly forms an antenna loop () configured to detect the electromagnetic tags (). The antenna assembly () has a greater detection range in the deployed configuration than in the collapsed configuration. The deployed configuration corresponds to a tuned shape of the antenna assembly () sufficient to detect the electromagnetic tags () in the deployed configuration.

A manifold for a medical/surgical waste collection system. An outlet opening and a fitting are in fluid communication with a manifold volume within a housing. The fitting receives a suction line. A filter element with porous features is disposed within the housing such that a fluid communication path is established across the filter element. The porous features trap material entrained within the fluid. A material collection volume is at least partially distal to and below a bottom of the filter element. As the fluid and the material is drawn through the fluid communication path, the material collects within the material collection volume. A flow diverter may be positioned within the housing for directing the material towards the material collection volume. The material collection volume may be at least partially defined by a tissue trap removably coupled to the housing.

A cassette for retrieving plural tissue samples from a fluid stream. The cassette includes a bypass conduit and plural voids. A catch tray is removably seated in each of the voids. A fitting extends from the cassette. The cassette has an outlet opening through which a suction is drawn. The cassette also has a valve. The valve directs the fluid stream from the fitting so the fluid stream flows through the bypass conduit or through one of the voids in which a catch tray is seated.

A mill head for replaceable attachment to a base so as to collectively form a bone mill. The mill head includes: a first opening in which bone stock is introduced into the head; a cutting device that converts the bone stock into bone chips; a second opening through which the bone chips are discharged; and a third opening through which a motor integral with the base is attached to the cutting device. Internal to the mill head are containment rings. The containment rings prevent the discharge of material through the third opening. The containment rings are services the internal component of the mill head on which the cutting device rests.
