    摘要： A surgical stapler for use by a surgeon to place one or more rows of surgical staples in organs or tissue. The stapler is of a character having a supporting frame, a replaceable staple cartridge, an anvil, a mechanism for approximating the cartridge relative to the anvil, and a mechanism for firing the device so as to crimp the staples against the anvil. The device, while at all times permitting approximation of the cartridge relative to the anvil, provides a novel safety mechanism that clearly indicates to the surgeon that the staples have been fired from the staple cartridge and simultaneously disables the device until it is manually reset.

    摘要： A medical backcheck valve includes a hollow housing containing an upwardly biased piston assembly for controlling liquid flow therethrough. The piston assembly comprises a substantially rigid plug having one end protruding from the upper end of the housing, and a flexible sheath covering having a relatively small diameter upper end surrounding the plug, a main seal for controlling flow through said first flow space, and a tubular lower end, secured at the bottom of the housing, for preventing liquid from entering within the covering.

    摘要： An implantable fluid delivery device for dispensing metered aliquots of liquid medication upon finger-pressure activation of the device by a patient. The device includes a soft, deformable needle-piercable casing having a fluid reservoir in which is located a relatively-rigid, apertured support plate that divides the reservoir into upper and lower chambers. A compressible, positive displacement pump chamber or housing is mounted upon the plate within the upper chamber and includes passages communicating with both the lower chamber and an outlet port. Force applied to a central target zone of the top wall causes compression of the pump housing and delivery through the outlet port of an amount of fluid equal to the displacement of the pump housing. The same target zone of the top wall serves as a self-sealing injection site for replenishing the fluid supply of the reservoir. A rigid, protective needle guard is disposed within the upper chamber above the pump housing to shield that housing against contact by an injection needle when the fluid supply is being replenished. The rigid plate that supports the pump housing also distributes applied pumping forces and provides a platform for supporting other elements of the device, including a fluid filter and surge protector located in the lower chamber of the reservoir at the inlet to the pump housing.

    摘要： A stapling instrument including two elongate structural members each comprising a handle part with a jaw part projecting from a first end. The structural members have pivot means at second ends of their handle parts adapted for free engagement and disengagement and relative pivotal movement of the structural members between open and closed positions. An elongate locking member is mounted one one of the structural members for pivotal movement to a locking position generally aligned with its handle part where the locking member can be releasably retained to forcefully move the structural members to their closed position so that high compressive forces can be applied to tissues between the jaw parts. Staples from a cartridge along one jaw part can then be driven through the tissue and closed against an anvil along the other jaw part. One of the structural members has a support element in contact with the other of the structural members transverse of a space between the handle parts when the structural members are in their closed position to restrict bending and movement of the handle parts toward each other in response to separating forces applied between the jaw parts as a result of compressed tissues so that the staples can be properly closed.

    摘要： An external ventricular drainage assembly includes a ventricular drainage catheter which can be placed in the ventricles of a patient's brain and which is connected to a suture tab for securing the catheter to the patient and for preventing relative movement between the catheter and patient. A valve is connected to the catheter for selectively opening and closing the external ventricular drainage assembly to fluid flow. An adapter is connected to the valve for providing access to the fluid flow path within the assembly. A one-way valve is connected to the adapter. A first length of flexible tubing is connected to the one-way valve and is joined through a connector to a second length of flexible tubing. A collection reservoir is connected to the second length of flexible tubing and includes an entry and outlet port. A drip chamber is positioned between the second length of flexible tubing and the collection reservoir.

    摘要： A catheter guide is provided which has a base having a first channel extending thereacross for receiving a catheter. An arcuately extending member extends outwardly from the base. A second channel extends along the arcuately extending member for also receiving a catheter. The first and second channels extending respectively across the base and along the arcuately extending member can be enclosed or partially enclosed for retaining a catheter within the channels and within the catheter guide.
