A cutting assembly configured to be removably coupled to a drive assembly of a surgical instrument. An inner tube is coaxially and rotatably disposed within an outer tube and defines a lumen in communication with a cutting window. A projection is disposed within the lumen of the inner tube. The projection may include a distal first portion displaced radially inward relative to an interior surface of the inner tube, and a proximal second portion angled relative to the distal first portion. A distance between a proximal boundary of the cutting window and a nearest point on the projection may be less than a diameter of the lumen. An inner surface of the projection permits cutting action to continue until the material is sufficiently reduced to pass between a proximal boundary of the cutting window and the insert. The projection may be formed by an insert secured within the inner tube.

Cutting assembly for surgical instrument with clog-reducing tip

A cutting assembly configured to be removably coupled to a drive assembly of a surgical instrument. An inner tube is coaxially and rotatably disposed within an outer tube and defines a lumen in communication with a cutting window. A drive hub is coupled to a proximal end of the inner tube to define a suction path through the hub member and the inner tube. A hub member of the drive hub defines a first aperture, and further defines a reduced aperture. A diameter of the lumen of the inner tube is less than the inner diameter of the reduced aperture of the drive hub such that resected tissue moves from smaller to larger cross sectional portions of the suction path at an interface between the drive hub and the inner tube. The drive hub may include a lip disposed within the suction path with the inner tube abutting the lip.

Cutting assembly for surgical instrument with clog-reducing hub

A cutting assembly for a surgical instrument. A tube assembly includes an outer tube having an outer cutting window, and an inner tube coaxially disposed within and rotatable relative to the outer tube. The inner tube includes an inner cutting window such that the inner and outer cutting windows define a cutting window of the tube assembly. A portion of the inner tube distal a proximal boundary of the cutting window may define a distal region of the inner tube. A projection is within a lumen of the inner tube with at least a portion of the projection disposed within the distal region. The projection may be an insert. The projection occupies a volume of the distal region and/or reduces a cross-sectional area of the lumen distal to the proximal boundary. The projection reduces the size of material removed through the cutting window to reduce clogging of the tube assembly.

Cutting assembly for surgical instrument with clog reducing tip

A cutting assembly for a surgical instrument. The cutting assembly comprises a tube assembly having an inner tube adapted to be rotated by a drive assembly, and an outer tube disposed over the inner tube. An aperture within each of the inner and outer tubes may define a cutting window adapted to be applied to a surgical site of a patient. A grip is coupled to the tube assembly and configured to be engaged by a hand of a user. A manually movable member for rotating the outer tube may be provided and rotated with an index finger or a thumb of the hand while the grip is engaged by a web of the hand. A web portion of the grip may be engaged by the web of the hand without being engaged by a palm of the hand. Methods of gripping a cutting assembly are also disclosed.

Provided herein is a biological detection system and method of use wherein the biological detection system comprises at least one mixer or liquid bridge for combining at least two liquid droplets and an error correction system for detecting whether or not proper mixing or combining of the two component droplets have occurred.

Biological detection system and method of use

A multi-port liquid bridge () adds aqueous phase droplets () in an enveloping oil phase carrier liquid () to a draft channel (). A chamber () links four ports, and it is permanently full of oil () when in use. Oil phase is fed in a draft flow from an inlet port () and exits through a draft exit port () and a compensating flow port (). The oil carrier and the sample droplets () ('aqueous phase') flow through the inlet port () with an equivalent fluid flow subtracted through the compensating port (). The ports of the bridge () are formed by the ends of capillaries held in position in plastics housings. The phases are density matched to create an environment where gravitational forces are negligible. This results in droplets () adopting spherical forms when suspended from capillary tube tips. Furthermore, the equality of mass flow is equal to the equality of volume flow. The phase of the inlet flow (from the droplet inlet port () and the draft inlet port () is used to determine the outlet port () flow phase.
