Finally, the controller is configured to move the actuator in response to the instructions from the external remote control, wherein the actuator adjusts the implant body. The methods may include measuring a parameter indicative of a biological condition; transmitting data associated with the parameter from the implantable device to an external remote control; transmitting instructions from the external remote control to the implantable device; and actuating the bone growth device in response to the instructions from the external remote control.
Device and method for producing a micro-graft matrix from full-thickness skin
A device set and a method for producing a micro-graft matrix with a plurality of punched full-thickness skin parts (12) from skin includes a film set of at least one first film (1) and one second film (2), which adhere to and are peelable from one another; an adhesive (10) to stick the first film (1) onto the skin; a cutting device with an adapter to provide a predefined distance to the skin and to make a plurality of hollow-cylindrical cuts vertical to the film set down to a predetermined depth in the skin underneath, the film set being respectively cut and divided, so that an outer portion of the second film can be peeled off and inner portions remain; and a third film (3), stuck in contact with the second film (2). The punched full-thickness skin parts can be extracted from the skin as the micro-graft matrix using the third film (3).
Ultrasonic transducer techniques for ultrasonic surgical instrument
A method of fabricating an ultrasonic medical device is presented. The method includes machining a surgical tool from a flat metal stock, contacting a face of a first transducer with a first face of the surgical tool, and contacting a face of a second transducer with an opposing face of the surgical tool opposite the first transducer. The first and second transducers are configured to operate in a D31 mode with respect to the longitudinal portion of the surgical tool. Upon activation, the first transducer and the second transducer are configured to induce a standing wave in the surgical tool and the induced standing wave comprises a node at a node location in the surgical tool and an antinode at an antinode location in the surgical tool.
Bone and tissue resection devices and methods
Embodiments of devices for converting continuous rotational motion into oscillating motion are disclosed herein. In one embodiment, an oscillation device can include an input shaft that rotates about a first axis, a portion of the input shaft defining an eccentric section that defines a second central axis offset from the first axis, a connector rotatably coupled around the eccentric section, an oscillating shaft offset from the input shaft that rotates about a third axis, and a pin coupled to the oscillating shaft and extending towards the connector. The connector includes a sleeve slidably receiving an end of the pin, and continuous rotation of the input shaft about the first axis causes an eccentric movement of the connector, and the eccentric movement of the connector oscillates the sleeve along the pin and oscillates the pin with respect to the oscillating shaft, thereby oscillating the oscillating shaft about the third axis.
