A medical power supply system includes: a medical device including an elongated insertion section, a power receiving unit including a power receiving member and movable relative to the insertion section in a longitudinal direction of the insertion section, and a biasing unit biasing the power receiving unit toward a distal end side of the insertion section; and a guide unit including a power transmitting unit including a power transmitting member, the insertion section being inserted into the guide unit. When the insertion section is inserted into the guide unit to a predetermined amount, the power receiving unit comes in contact with the power transmitting unit with being biased by the biasing unit, and the power transmitting member and the power receiving member face each other in an axial direction of the insertion section and have a positional relation in which wireless power transmission is possible.

A microneedling machine for tattooing is disclosed, which has a substantially radially symmetric exterior shape and may include subcomponents that can be disassembled and sterilized. The machine may include an adjustment mechanism for configuring the impact of the microneedle into skin. The machine may also include a motion translation device adapted to change rotational motion of the drive shaft or motor into linear reciprocating motion of the microneedle.

An intraosseous access system to access a medullary cavity includes a driver including an access assembly, a motor, and an energy source. The intraosseous access system further includes a sensor configured to detect a first input from one of the motor or the energy source. The intraosseous access system further including a processing unit, communicatively coupled with the sensor, configured to receive the first input from the sensor, and determine access to a medullary cavity. The processing unit can then modify operation of one of the motor and the energy source to automatically stop operation of the system and prevent backwalling.

Embodiments of the present disclosure provide an apparatus and method for reducing surgical smoke. An exemplary apparatus includes trocar comprising a tubular hollow body circumscribing a cavity extending through a longitudinal axis of the trocar with a gasket at a first end and an exit port at a second end, the tubular hollow body comprising a first wall circumscribing the cavity and a concentrically spaced apart second wall. The apparatus further includes a first plate operable to maintain an electric charged disposed within the cavity on the first wall, and a second plate operable to maintain an electric charge disposed between the first wall and the spaced apart second wall.

Devices and methods for the treatment of chronic total occlusions are provided. One disclosed embodiment comprises a method of facilitating treatment via a vascular wall defining a vascular lumen containing an occlusion therein. The method includes inserting an intramural crossing device into the vascular lumen, positioning at least the distal tip of the crossing device in the vascular wall, advancing an orienting device over the crossing device such that an orienting element of the orienting device resides in the vascular wall, inserting a reentry device, and re-entering the true vascular lumen.

An electrosurgical generator, a control device, a method for operating the electrosurgical generator and a computer program product. The electrosurgical generator includes an ultrasonic generator for providing an excitation signal by which an ultrasonic converter can generate an ultrasonic vibration, a radiofrequency generator for providing a radiofrequency energy at two output contacts, and a control unit adapted to independently activate the radiofrequency generator and the ultrasonic generator. The control unit is further adapted to determine a DC-offset voltage between the two output contacts of the radiofrequency generator, check if the DC-offset voltage exceeds a DC-offset threshold value, and deactivate the ultrasonic generator if the DC-offset voltage does not exceed the DC-offset threshold.

An adapter assembly includes a trocar assembly releasably securable within an elongate body and including a chip. The adapter assembly may further include a housing supporting a circuit board. The chip electrically communicates with the circuit board when the trocar assembly is received within the distal portion of the elongate body.

A method of forming an access opening through a psoas muscle to a patient's spine includes laterally inserting a stimulating dilator into the psoas muscle. The stimulating dilator has a stimulation channel formed in an outer surface thereof. An electrical pulse is transmitted via an EMG into the stimulating dilator to locate a position of a nerve in the patient's psoas muscle. The stimulating dilator is laterally inserted through the psoas muscle and toward the patient's spine in a way that avoids the nerve. A stimulating probe is inserted into the stimulation channel along the outer surface of the stimulating dilator while transmitting an electrical pulse via the EMG into the stimulating probe to verify the position of the nerve.

This endoscopic energy treatment instrument includes: a treatment instrument insertion part having flexibility and having a power reception part that is capacitively coupled by facing to a power transmission electrode arranged in a treatment instrument channel provided in an endoscope; a treatment part that is arranged on a distal end of the treatment instrument insertion part, and that uses electric power supplied from the power reception part to perform energy treatment; and a cleaning part that is arranged on the treatment instrument insertion part between the power reception part and the treatment part so as to be able to come into contact with the treatment instrument channel, the cleaning part being configured to clean an inside of the treatment instrument channel in accordance with a movement of the treatment instrument insertion part.

An adapter assembly for operably connecting an end effector to a surgical instrument. The adapter assembly includes a first proximal shaft, a second proximal shaft, a first distal shaft, and a second distal shaft. The first proximal shaft includes a first gear assembly. The second proximal shaft defines a longitudinal axis and includes a second gear assembly. The first distal shaft is disposed along the longitudinal axis and includes a third gear assembly. The first gear assembly is mechanically engaged with the third gear assembly. The second distal shaft includes a fourth gear assembly. The second gear assembly is mechanically engaged with the fourth gear assembly. A distal portion of the second distal shaft is disposed at least partially within an internal cavity of the third gear assembly.
