A saw blade cartridge comprises a saw blade and a cassette. The cassette is disposed over a proximal portion of the saw blade and includes first and second cassette portions opposing each other across the proximal portion. Each portion comprises a shell and a damper. The shells are of a first stiffness and have an outer side. The dampers are of a second stiffness less than the first stiffness and are disposed on an inner side of the shell. The cassette portions are substantially fixed relative to the proximal portion and are substantially aligned with each other. The shells are fixed to each other. The dampers contact the proximal portion. A handpiece coupler for engaging either of the saw blade cartridge or a saw blade includes a release button with a lock button slidably disposed therein to resist unintended opening.

A surgical handpiece system for use with a drill bit having an identification feature that includes magnetic material. A handpiece transfers torque to the drill bit to rotate the drill bit. A measurement module that includes a housing is coupled to the handpiece. A measurement cannula made of a non-magnetic material surrounds the drill bit during operation. The measurement cannula extends forward or rearward relative to the housing and has a distal end adapted for placement against a workpiece. A transducer assembly generates a transducer signal based on a position of the measurement cannula relative to the housing. A sensor generates an identification signal responsive to a magnetic field or magnetoresistance of the identification feature of the drill bit through the measurement cannula during operation. A controller receives the identification signal and identifies the coupled drill bit corresponding to the received identification signal.

Systems and methods for performing spine surgery. A retractor may be positioned within a patient to facilitate maintaining a volume of fluid at the surgical site. The retractor includes an opening capable of receiving one or more surgical instruments, for example, a cutting instrument and an endoscope. A cutting member of the cutting instrument is submerged and operated within the volume of fluid to resect tissue, for example, within the intervertebral disc space. The volume of fluid is maintained at the surgical site improves cooling of the surgical site and visualization of the surgical site via the endoscope during resection. The volume of fluid is maintained at the surgical site via the surgical system. The surgical system may include a sensor for measuring the level of fluid in the retractor, an inflow source and an outflow source in fluid communication with the retractor, and a controller controlling the surgical system.

A surgical drill for drilling a hole in a workpiece includes a housing, a probe moveably mounted to the housing, and a transducer assembly. The transducer assembly includes a gear coupled to the probe and at least two rotational sensor devices coupled to the gear to determine an amount of movement of a probe relative to a housing to determine a bore depth of the hole. The gear has a reference point having an angular path of rotation about a gear axis subdivided into separate first and second arcuate regions. A first sensor device is configured to detect a rotational position of the reference point in the first arcuate region, and a second sensor device is configured to detect a rotational position of the reference point in at least the second arcuate region, with the first sensor device incapable of detecting the reference point in the second arcuate region.

A waste collection system for collecting medical/surgical waste. A mobile rover includes at least one waste container supported on the mobile rover for storing the medical/surgical waste. A chassis is separate from and configured be removably coupled with the mobile rover. The chassis supports a chassis controller and a vacuum pump configured to draw a vacuum on the waste container. A rover controller is supported on the mobile rover and configured to receive a pressure signal representative of a level of the vacuum. The chassis controller is configured to be in communication with the rover controller and to regulate the level of the vacuum drawn based on the pressure signal. A transmitter may be supported on the mobile rover and in communication with the rover controller, and a receiver may be supported on the chassis to be in communication with the transmitter to establish a communication circuit for data transfer.

Measurement head for surgical tool

A surgical handpiece includes a shell, an energy applicator, a transmission component, a lid, a latch and a data tag. The shell defines a void for receiving a power module and an opening through which the power module is inserted into and removed from the void. The energy applicator is attached to the shell. The energy applicator, when actuated, outputs energy for application to a tissue to perform a medical/surgical task. The transmission component is disposed in the shell for transmitting energy output by the power module to the energy applicator. The lid moveably is mountable to the shell to cover the shell opening. The latch is moveably attached to the shell or the lid for holding the lid in a latched state. The data tag is mounted to the latch so as to move with the latch, the data element including data identifying the handpiece.

A drill bit comprises a shank extending along an axis and an interface comprising at least one outermost drive portion spaced at a first interface distance from the axis. The drill bit further comprises a resilient arm extending from a proximal end of the shank. The resilient arm comprises an outer arm surface facing away from the axis and a retention surface facing toward a distal end of the shank. The retention surface may be radially aligned about the axis with respect to the outermost drive portion. The resilient arm is movable between: a first position where the outer arm surface is spaced from the axis at a first arm distance greater than the first interface distance, and a second position where the outer arm surface is spaced from the axis at a second arm distance less than or equal to the first interface distance.

A waste collection system for collecting waste during medical/surgical procedures including a mobile container cart with a waste container. A container cart is selectively coupled to a suction cart that includes a vacuum pump. The connection of the carts results in the connection of the vacuum pump to the waste container. The vacuum pump draws a vacuum that results in waste being drawn through a suction line into the waste container. The container cart holds instruments that can be removably attached to the container cart. This facilitates the configuration of the container cart for the specific procedure for which it is necessary to draw a suction.

A surgical sagittal saw blade with first and second elongated openings. The openings have major axes that are angled relative to each other. The openings are arranged to receive draw for pivoting a blade in a sagittal plane. Each opening receives a separate drive member integral with the saw to which the blade is mounted. The action of one drive member in a first opening results in the proximal to distal reciprocation of the blade. The action of a the second drive member in the second opening results in the back and forth pivoting of the blade around an axis that extends through the plane of the blade. The blade has a constraining feature that engages a complementary constraining feature integral with the saw. The engagement of the constraining features limits the reciprocal and pivotal movement of the blade.

A saw for pivoting a blade in a sagittal plane. The saw includes a drive assembly with at least one drive member. The drive assembly is configured to both reciprocate the blade in the sagittal plane and to simultaneously pivot the blade around an axis that extends through the sagittal plane. The drive assembly is configured to reciprocate and pivot the blade at different frequencies. Consequently the teeth () of the blade travel in a loop pattern that crosses itself.
