摘要:
A tip for a medical device includes a hollow body having a window, a sensor positioned within the hollow body and oriented such that its active surface is pointed towards the window, and a membrane positioned within a beam path of the sensor. The membrane passes energy without preventing an outer surface of the hollow body of the tip from coming in contact with tissue, thus allowing the hollow body to deliver therapy to an adjacent tissue and/or diagnose adjacent tissue. The membrane can cover the window or the sensor. The membrane is desirably permeable to an irrigant, such that a suitable level of irrigant outflow from the window is maintained, and thin enough that it minimizes attenuation of energy passing to and/or from the sensor.

An injection cannula includes a hand-held mechanical motorized device to improve delivery of fat and facilitate dispersion at a recipient site. The injection cannula may, for example be a cannula for injecting fat in a cosmetic surgical procedure for fat transplantation such as percutaneous injection or injection directly into the subcutaneous fat. An electric motor, pneumatic motor, or other mechanism may be used to provide vibration.

An irrigation and suction tip (20) for laparoscopic surgery having an increased range of transport within a surgical cavity during laparoscopic surgery. The tip (20) moves in a circumferential trajectory rather than linearly when a surgeon is irrigating and suctioning tissue. The tip is substantially resilient, withstanding great force and pressure during irrigation and suction procedures. The tip (20) is bowed, having a pair of straight portions, a short distal portion (20D) and a long proximal portion (20P) joined by a bowed portion, (20B) the bowed portion allowing the distal portion to rotate, circumscribing a large area. The bow is limited so that the tip moves within a narrow wall of a cannula (14) of a trocar.

A medical device includes an end effector and a fluid control system configured to control fluid generated when the end effector applies energy to target tissue and includes a fluid path element having one or more fluid paths. The one or more fluid paths include a distal fluid port positioned adjacent to a working portion of the end effector and a proximal fluid port fluidically coupled to a supply and transport element. The supply and transport element is configured to one of evacuate and supply fluid adjacent to the working portion of the end effector. The supply element may be operatively coupled to an activation element configured to activate the supply and transport element when end effector applies energy to the target tissue.
摘要:
A phacoemulsification system and method, and a foot pedal device, system and method. The devices, systems and methods may include a console comprising a plurality of modes for at least one physically associated surgical instrument, and a foot pedal communicatively associated with said console and suitable for varying ones of the plurality of modes. The foot pedal may include a foot pedal base, and at least two electronically actuated sensors physically associated with the foot pedal base, communicatively connected to the console, and suitable for receiving physical indications of variations in ones of the plurality of modes.

Dispositif d'hémostase pour une cavité corporelle comprenant - un conduit tubulaire (1 ) ayant une extrémité distale (2) et une extrémité proximale (3), - un ballon distal (6) et un ballon proximal (7) -trois tubes, d'alimentation ou de récupération de fluide, dont une partie de la longueur est installée dans le conduit tubulaire, le ballon distal (6) et le ballon proximal étant co-axialement espacés le long du conduit, le ballon distal (6) étant installé à l'extrémité distale du conduit tubulaire, le ballon proximal étant installé de manière étanche aux liquides autour d'une portion du conduit tubulaire, un (5) des trois tubes débouchant dans le ballon distal (6), un autre (8) des trois tubes débouchant dans le ballon proximal, le troisième des trois tubes (9, 10) débouchant dans un espace extérieur au conduit, situé entre le ballon distal (6) et le ballon proximal (7).
摘要:
According to some embodiments, a method of treating a skin surface of a subject comprises heating a skin surface, abrading native skin tissue of a subject using a microdermabrasion device, wherein using the microdermabrasion device comprises moving the microdermabrasion device relative to the skin surface while simultaneously delivering at least one treatment fluid to the skin surface being treated and cooling the abraded skin surface.
摘要:
A surgical sponge and fluid monitoring system and method are provided. The system (100) includes a support ring (104) for securely supporting a container (101) with at least one port opening (206) for placing sponges (204) into the container through the at least one port opening with the aid of gravity. The support ring includes IR emitters and sensors (604) that blanket IR beams (1402, 1404) across the at least one port opening. The support ring is mechanically linked to a load cell (706, 1329) in the system. The processor (1302), with novel methods, reliably detects when sponges are placed into the container through the at least one port opening, counts the number of sponges in the container, sorts the types of sponges, and calculates fluid loss for a patient in a surgical procedure. A user interface (1308, 114) in the monitoring system keeps the medical professionals (502) in the operating room fully informed.
摘要:
An ultrasonic surgical drill or drill bit includes a tubular member having a longitudinal axis of symmetry and a plurality of fins extending in longitudinal planes each containing the axis. In a surgical method utilizing the drill bit, one places a distal tip of the drill bit in contact with bone, presses the drill bit against the bone, and during that pressing of the drill bit, conducts ultrasonic vibrations into the drill bit. With the fins in contact with the bone, the drill bit is oscillated or angularly reciprocated about a longitudinal axis, so that the fins fragment bone material located between the fins.
