A method includes sensing magnet information at a plurality of magnet positions on a cannula and determining identification information for the cannula based on the magnet information.

The present disclosure relates to an apparatus for providing access to bone marrow and delivering a quantity of fluid to an intraosseous space. The apparatus may include a driver having a housing and a drive shaft, and a plunger operating and cartridge drive mechanism for releasably retaining a portion of a cartridge assembly having a plunger assembly. A plunger operating assembly may be disposed within a longitudinal bore of the plunger operating and cartridge drive mechanism. The plunger operating assembly may include a plunger barrel having a chamber configured to receive a portion of the plunger assembly of the cartridge assembly. The apparatus may also include a drive housing for transmitting rotational forces from the drive shaft to the cartridge assembly.

An optically transparent actuator apparatus is provided that includes an optically transparent bi-stable member including an optically transparent liquid crystalline polymer layer. The bi-stable member is structured to move from a first state to a second state in response to a first stimulus and from the second state to the first state in response to a second stimulus. Also, a display apparatus includes a plate member and an actuator assembly coupled to the plate member. The actuator assembly includes a number of optically transparent liquid crystalline polymer layers, wherein each of the optically transparent liquid crystalline polymer layers is structured to move from a first state to a second state in response to a first stimulus.

A hair transplanter includes: a needle channel bundle including a center shaft and a plurality of needle channels coupled to an outer circumference of the center shaft to be slidable up and down; a channel rotation unit configured to rotate the needle channel bundle by a predetermined angle corresponding to one needle channel; and a push bar disposed on an upper portion of the needle channel bundle, and configured to push down one needle channel of a predetermined position, wherein each of the needle channels includes a body having a tubular inner space formed therein, a needle coupled to a lower end of the body, and a core shaft slidably disposed in the tubular inner space and the needle, wherein the plurality of needle channels are arranged on the outer circumference of the center shaft radially at equal intervals with reference to a center axis of the center shaft.

An apparatus includes a shaft assembly and an end effector. The shaft assembly includes an outer sheath and a staple driving mechanism. The end effector includes a staple deck, an anvil, a first staple driver, and a second staple driver. The staple deck defines a plurality of staple openings in at least one annular array. Each staple opening in the plurality of staple openings houses a staple. The anvil is configured to actuate relative to the staple deck to compress tissue between the staple deck and the anvil. The staple driving mechanism is configured to actuate the first staple driver to fire a first staple of the plurality of staples against the anvil. The staple driving mechanism is further configured to actuate the second staple driver independently of the first staple driver to fire a second staple of the plurality of staples against the anvil.

A robotic surgical system may include a cannula attachment device or cannula mount having a locking mechanism configured to pivot between an unlocked position and a locked over-center position. The locking mechanism may actuate a clamp or other feature that is configured to move between a closed position and an open position. The clamp may include a locating structure with one or more tapered surfaces that is configured to mate with a corresponding structure disposed on a portion of a cannula when the cannula is positioned in the cannula attachment device. The locating structure may guide the cannula into the attachment device, as well as assist with orientating the cannula relative to the attachment device.

A disposable device used for an intraosseous infusion is provided. The intraosseous infusion device includes a driver including a motor and a power unit and an internal trocar manufactured to be integral with the driver. An intraosseous infusion procedure is performed in a sterile way since the internal trocar is integrated with the driver in the intraosseous infusion device.

A telescoping assembly such as an endobronchial ultrasound needle (EBUS) assembly includes a motor coupled to a biopsy needle within a telescoping housing to rotate (such as to oscillate) the needle during tissue harvest to improve harvesting.

Marker systems and methods for implanting a marker are provided. In one embodiment, a marker system can include an elongate cannulated tube, a marker capsule, and a driver member. The cannulated tube can have a piercing feature arranged at a distal end thereof that is configured to create a working portal through tissue such that fluid can be delivered into the tissue to form a bleb. The marker capsule can be removably disposed within the lumen of the cannulated tube. The marker capsule can include a transmission antenna, and an arranging feature disposed on an external surface configured to facilitate rotation of the marker capsule within the bleb. The driver member can be arranged within the lumen of the cannulated tube proximal to the marker capsule. The drive member can be configured to advance distally to displace the marker capsule through the working portal and into the bleb.

An apparatus for penetrating bone and accessing bone marrow is provided. The apparatus may include a penetrator assembly and a powered drill to penetrate the bone into the bone marrow. The penetrator assembly may include a trocar having a stylet. The penetrator assembly may also include an outer penetrator having a hollow cannula and a luer lock attachment. The powered drill may include a housing enclosing a motor and a power supply and associated circuitry. The powered drill may also include a connector receptacle for receiving a penetrator assembly connector of the penetrator assembly. The connector receptacle may releasably lock the penetrator assembly connector into place with the powered drill. The power supply may include a rechargeable battery within the housing for supplying power to the motor. A battery indicator may be provided to indicate a level of the battery.
