摘要： A paste injector gun, especially adapted for injecting bone cement, has first and second mechanical advantages. In a first embodiment, the first and second mechanical advantages are produced by two fulcrums engageable during different portions of the trigger stroke. In a second embodiment, the first and second mechanical advantages are produced by a fixed fulcrum and a rotatable fulcrum. The first mechanical advantage is greater than the second such that the first facilitates pressurizing the bone cement and the second facilitates high volume dispensing of the bone cement. The injector gun also includes a pair of U-shaped slots. One of the slots is sized to accept a large cement cartridge and the other slot is sized to accept a small cement cartridge. An alternative embodiment provides a hinged cartridge retaining gate for closing the U-shaped slots for positive retention of the cartridge.
摘要翻译： 特别适用于注射骨水泥的糊注射器枪具有第一和第二机械优点。 在第一实施例中，第一和第二机械优点由在触发行程的不同部分可接合的两个支点产生。 在第二实施例中，第一和第二机械优点由固定的支点和可旋转的支点产生。 第一机械优点大于第二机械优点，使得第一机械优点使得第一机械优点有利于对骨粘固剂进行加压，而第二机构有助于骨水泥的高体积分配。 喷射器枪还包括一对U形槽。 其中一个槽的尺寸适于接纳大型水泥筒，另一个槽的尺寸适于接纳一个小水泥筒。 一个替代实施例提供了一个用于封闭U形槽的铰链盒保持门，用于保持盒的正向保持。

摘要： A method and apparatus for mixing bone cement which produces bone cement essentially free of entrained air. The apparatus includes a cartridge having two telescoping cylinders. The outer cylinder receives a cap thereon which hermetically seals the cartridge. The cap includes an outlet port in which a break-away agitator is installed and a port for connection of a vacuum pump. In use, a desired vacuum pressure is drawn on the cartridge and the inner cylinder is allowed to be drawn into the outer cylinder while the vacuum is being drawn, whereupon the inner cylinder automatically stops moving relative to the outer cylinder when the desired vacuum pressure is reached. Mixing of the bone cement is then performed under the partial vacuum thereby created. The agitator paddles provide a scraping action against both inner cylinder walls of the telescoping cylinders thereby improving mixing. After mixing, the agitator is broken away, an appropriate nozzle is attached to the cartridge and the cartridge is inserted into a cement gun. The leading portion of the bone cement develops a convex profile when axially advanced through the cartridge and the piston plug includes a tapered protrusion which generally corresponds to the profile of the bone cement. The cap and paddles are also shaped correspondingly to the convex profile developed by the bone cement, resulting in substantially all of the bone cement being squeezed from the cartridge. An air escape passage is also provided to vent air contained within an annular gap between the agitator shaft and the cap upon initial being essentially free from entrained air.

摘要： Methods for impaction grafting an intramedullary canal of a bone including a first canal portion and a second canal portion spaced along a canal axis. A first tamp may be moved axially within the canal to impaction graft the first canal portion. A second tamp may be mounted to the first tamp in axial sliding relationship and moved axially within the canal relative to the first tamp to impaction graft the second canal portion. The first and second tamps may be locked together in fixed axial relationship to prevent relative axial movement between the first tamp and the second tamp while the first tamp is moved to impaction graft the first canal portion before impaction grafting the first canal portion. The first and second tamps may be unlocked to permit relative axial sliding of the first and second tamps before impaction grafting the second canal portion.

摘要： A hip stem centralizer datum guide (40, 100, 200, 300) and method are provided for positioning a proximal portion of a hip stem component (44) within bone cement in an intramedullary canal of a femur. The datum guide is positionable in a predetermined position relative to the intramedullary canal and is able to create a datum (70, 72, 74, 76, 120, 220, 302) that records the predetermined hip stem component position relative to the intramedullary canal. The datum is able to be referenced to position the hip stem component in the predetermined hip stem component position in the bone cement in the intramedullary canal.
