A flow controllable type suction and irrigation device includes: a handle having an installation space therein; a cannula provided with a conductive tube and an insulating protective tube, the conductive tube extending in a forward direction of the handle to be inserted into the abdominal cavity of a patient and being coupled to an electrode for surgery, the insulating protective tube being disposed to surround the conductive tube; and a suction supply unit provided to the handle and supplying an irrigation fluid to the cannula or suctioning blood or contaminants from the abdominal cavity of the patient through the cannula.

A medical device system includes an insertion device and a medical device. The insertion device includes an insertion device handle, including a port on a handle body. The insertion device also includes an insertion device shaft extending from the insertion device handle. The insertion device shaft includes a working channel connected to the port. The medical device includes a medical device handle, including a movable handle portion and a stationary handle portion. The movable handle portion includes a ball portion movably positioned within a cavity in the stationary handle portion. The medical device also includes a medical device shaft. The medical device shaft is configured to be delivered through the port in the insertion device handle and through the working channel in the insertion device shaft. Movement of the movable handle portion relative to the stationary handle portion controls movement of a distal portion of the medical device shaft.

A suction and irrigation valve for a robotic surgical system includes a shaft assembly, a rotary drive, and a valve assembly. The valve assembly is operatively connected to the rotary drive member and includes a valve body and a valve plug. The valve body has a first fluid inlet, a second fluid inlet, and an outlet. The valve plug is received with the valve body and is configured to rotate about a plug axis relative to the valve body to a first position, a second position, and a third position. The valve plug has at least a first conduit configured to selectively fluidly communicate with each of the outlet and at least one of the first or second fluid inlets.

Provided herein are expandable devices, rail systems, and motorized devices. In one embodiment, an expandable device comprises an expandable sac having a tool housed therein. The expandable device is optionally configured for operation while inside a body cavity. The expandable device optionally comprises at least one rail in the sac, and at least one railed device coupled to the rail for movement there on. Movement of the railed device on the rail is provided by, for example, a motor such as an electromagnetic motor or an inch-worm type motor. Expandable devices can be used, for example, to perform minimally invasive medical procedures requiring access to a body cavity. Expandable devices can also be used, for example, to provide safe and stable transport of instruments to the body cavity.

Systems and methods are disclosed for medical devices which can operate within a person in connection a medical procedure. In aspects of the present disclosure, a system for assisting with a surgical procedure includes a swarm of medical devices sized to be wholly deployed within a surgical site of a patient where the swarm of medical devices is configured to operate concurrently within the patient to assist a surgeon to perform a surgical procedure in the patient. The swarm of medical devices includes a first medical device that includes an imaging system configured to capture a view of at least a portion of a surgical site and to communicate the captured view, and a second medical device that includes one or more of a retracting device, an irrigation device, a suction device, a clipping device, a therapy delivery device, or a cutting device.

Disclosed herein are improved neural depth probes for detection and stimulation, along with various related improved components, devices, methods, and technologies. More specifically, the devices are layered depth electrodes with at least two layers, with each of the layers containing at least one thin-film trace disposed thereon. Each of the devices can also have a plurality of layers with at least two traces on each layer and contacts coupled to each trace.

A method for determining a characteristic of material at a target is provided. A target is illuminated with a pulsed light source. A fluorescence signal from the target when the pulsed light source is an “off” state is then sensed. Based on analysis of the fluorescence signal, a characteristic of material at the target is identified. A device can then be controlled based on the identified characteristic of the material at the target.

A skin treatment device and a method to cleanse and balance pH value of skin. The skin treatment device includes a nozzle to be directed into contact with the skin of a subject. A vacuum pump may be operably coupled to the nozzle for generating a suction force of the nozzle to evacuate impurities from the skin. A liquid replenishing assembly may be operably coupled to the nozzle for atomizing liquid at a pre-defined pH value. The liquid from the liquid replenishing assembly may pass into the nozzle based on the pre-defined pH value. The first control valve may be connected to an outlet of the vacuum pump and an outlet of the liquid replenishing assembly for communication with the nozzle.

Provided herein are expandable devices, rail systems, and motorized devices, in one embodiment, an expandable device comprises an expandable sac having a tool housed therein. The expandable device is optionally configured for operation while inside a body cavity. The expandable device optionally comprises at least one rail in the sac, and at least one railed device coupled to the rail for movement there on.
