  • Patent number: 4904238
    Abstract: A hand-held cannula assembly for irrigating and aspirating opthalmic surgical sites includes as irrigation cannula circumscribed about an aspiration cannula and extending out through the forward end of the assembly from a reservoir for the irrigation fluid in the handle. Pressurized irrigation fluid is supplied to the reservoir through the rearward end of the handle and flows through openings in the irrigation cannula periphery into an annular flow passage between the two cannulas. An opening in the irrigation cannula issues the irrigation fluid at the surgical site. Aspiration fluid is drawn into the aspiration cannula which extends through the handle interior to an outflow opening at the rearward handle end. The irrigation/aspiration tip exterior is made to be smooth, protrusionless, unitary and one-piece in design to afford a minimum in tissue tearing at the surgical site, while also allowing improved irrigation fluid flow a the site.

  • Patent number: 4861333
    Abstract: Apparatus for aspirating and irrigating the rumen of a cow includes a nozzle connected to one end of a flexible tube and adapted to be slid down the cow's throat and inserted into the rumen. The other end of the tube is connected to a container which is adapted to be placed in a vacuumized condition by a hand-operated suction pump. When the pump is operated, toxic liquid and food in the cow's rumen is sucked into the nozzle, through the tube and into the container. A second tube is located in the first tube and is adapted to eject a spray of water for cleaning the nozzle and for irrigating the rumen. The water is contained in a tank which may be pressurized by compressed air at a veterinarian's office.

  • Patent number: 4787845
    Abstract: A device for use in oral and dental hygiene wherein an oral irrigator is provided for connection to a conventional syringe or the like for applying fluid under pressure to the irrigator. The irrigator has a downwardly tapered tip with one or more longitudinally formed channels fluidly connected to the fluid supply syringe, with the remaining circumference of the irrigator tip capable of holding away the gum tissue, whereby irrigating fluid under pressure is applied into the base of a periodontal pocket for cleansing purposes with the channels also providing an exit for the fluid and debris to prevent undue pressure build-up.

  • Patent number: 4769003
    Abstract: An instrument for preventing the splashback of potentially infectious fluids and body tissues during wound irrigation as well as for preventing needle impalement injury to patient or ancillary medical personnel comprises a hub (16) having a central bore (18) the proximal end of which will accept the tip of a syringe (14) and which is integrally joined to a narrow diameter tubule (22) extending from the distal end, said tubule being directed down the central longitudinal axis of a transparent, dome-shaped shield (24). Said shield is integrally joined at its proximal end around the hub and gradually enlarges in diameter towards its distal end, terminating in a circular rim (36). Said shield, when placed adjacent to a wound (40) to be irrigated, will effectively contain potentially infectious splashback (46) and prevent said splashback from contacting irrigator or other personnel, as well as protecting the patient and medical personnel from impalement injury due to contact with a needle.

  • Patent number: 4759349
    Abstract: A surgical instrument and support unit for enabling a user using one hand to probe an incision and illuminate, irrigate, and aspirate the incision. The surgical instrument has a probe with illumination, irrigation, and aspiration ports on the end. The probe is coupled to a handle having controls for the irrigation and aspiration functions. Light from a high intensity lamp in the handle is transmitted through an optical fiber to the illumination port. A heat sink enclosing the lamp draws heat away from the lamp and transfers the heat to the aspirated fluid passing through the heat sink. The support unit is controlled by a microcomputer and provides an electrical supply for the lamp and a pressurized fluid supply for irrigation. The sources of the irrigation fluid is a standard hospital flexible bag. A bladder inflated by an air pump pressurizes the flexible bag. The pump is also utilized to deflate the bladder to allow rapid changing of the flexible bag during a surgical procedure.

  • Patent number: 4637814
    Abstract: Method and apparatus for unidirectional irrigation of at least a portion of the gastrointestinal tract between a point of access thereto and a distant or remote point of the tract. The distal end of an irrigating tube is passed through a point of access to the gastrointestinal tract to a distant point in the tract beyond which irrigation is not desired. The irrigating tube has one or more apertures formed therein only in the region substantially proximate to the distal end thereof. In the case where the portion of the tract being irrigated is not already occluded at the distant point, the tract is then occluded at that point whereupon irrigant is introduced into the irrigating tube through a proximal end thereof whereby the irrigant passes through the irrigating tube and is discharged therefrom through the aperture into the gastrointestinal tract at the region of the occluded distant point thereof and flows unidirectionally through the tract towards and out from the point of access.

  • Patent number: 4617013
    Abstract: This invention is a method and an apparatus for surgical irrigation, aspiration and illumination comprising a cooperative irrigation, aspiration and illumination system wherein the three functions are cooperatively performed at the actual surgical area during surgery. A single hand-held instrument capable of simultaneously and cooperatively providing light, irrigation and aspiration in a single and simultaneous act is utilized in a preferred method of practicing this invention. The light flows around the aspiration tip, which in turn carries the irrigation member. The amount of irrigation and aspiration is controlled by a one-hand operation of the surgeon or other operating room attendant.
