  • Patent number: 4062360
    Abstract: An atraumatic method and apparatus for the removal of fluid from a surgical field having a fluid valve which is opened and closed responsive to the pressure about the fluid valve and a vacuum valve which is also opened and closed in response to the pressure about the fluid valve, and when opened, causes fluid to be passed through the fluid valve. In one embodiment, the fluid valve is made of collapsible tubing, flattened at its midsection so as to be normally closed, and connecting a fluid inlet and fluid outlet of a fluid removal housing. The fluid removal housing is further provided with a control port which may be opened or closed manually, and a connection to a vacuum source through the vacuum valve.

  • Patent number: 4061135
    Abstract: A binocular endoscope for diagnostic work, medical treatment and surgical procedures providing depth perception in the image of an object viewed. Image transmittal from the viewed object to the viewing station is through a non-distorting, high resolution, optical system utilizing long path length lens means. Selectable field viewing through 360.degree. of continuous rotation, with preservation with image conformity, is achieved through the use of a dove prism in combination with mechanical linkage to compensate for rotation effects. The apparatus also includes field illumination means, fluid input and exhaust channels and a manipulable surgical element.

  • Patent number: 4055179
    Abstract: A two-piece valve including a first tubular member having a flow passageway therethrough with a tapered valve seat formed at one end of the flow passageway. A second tubular member is provided having a flow passageway therethrough and a valve element mounted in the flow passageway on the axis thereof. The first and second tubular members are slidably telescopically engaged with each other with one end of the first tubular member slidably positioned inside one end of the second tubular member. The valve element of said second tubular member has a tapered valve surface formed thereon adapted to move into and out of sealing engagement with the tapered valve seat of the first tubular member when the tubular members are telescoped axially one inside the other. The taper angles of the valve element and seat are in the "self-holding" category so that when the valve element is firmly seated in the valve seat the parts will be retained in mating engagement without any additional retaining means.

  • Patent number: 4051852
    Abstract: A device for aspirating body fluids comprising, a valve assembly having a first port to receive body fluids, a second port for passage of the body fluids from the valve assembly, and a passageway communicating between the first and second ports. The valve assembly has one-way valve means associated with the passageway to permit passage of body fluids from the first port to the second port and prevent passage of body fluids from the second port to the first port. The device has port means communicating with the passageway intermediate the valve means and first port, with the port means being normally closed to prevent contamination of the device, and being openable to permit passage of fluid through the port means to the first port.

  • Patent number: 4048987
    Abstract: A surgical aid for retaining displaced material in a surgical site in its displaced position. The aid consists of a wire core of aluminum or aluminum alloy or stainless steel and a covering of a suitable elastomer, such as dimethyl polysiloxane polymer, organo-metallically bonded or otherwise contiguous thereto. The aid is malleable, non-toxic and compatible with cell metabolism. It can be clamped to a retractor frame fixed relative to a surgical site and has major advantages over the use of sponges, towels and other surgical aids now in use. The aid has a body portion and a handle portion which can be held by an assistant or clamped to the frame, allowing the assistant to assume a more productive role in the operation or dispensing with him completely.
