    摘要： A system includes a drill guide and a gauge wire. The drill guide has two arms rotatable relative to each other about a hinge, with each arm including a split portion of a guide. When the arms are in a closed configuration, the split portions come together to form a tubular guide. Because the arms can be opened and closed about the hinge, the guide can be split and removed from over a drill bit or pin without first removing the drill bit from the bone or the drill from the drill bit or pin. Each arm also includes a semicircular form which when the arms are closed defines a gauge wire hole parallel to the guide which is sized to receive a gauge wire. The gauge wire includes depth indicia along its length which is used to indicate the length of a fixation device for use in a procedure.

    摘要翻译： 一个系统包括一个钻子引导器和一个量规线。 钻子引导器具有两个相对于彼此围绕铰链可旋转的臂，每个臂包括导向件的分割部分。 当臂处于闭合构型时，分裂部分一起形成管状引导件。 因为臂可以围绕铰链打开和关闭，所以可以将引导件从钻头或销上方分离和移除，而无需首先从钻头或钻头将钻头从钻头或销上移除。 每个臂还包括一个半圆形的形式，当臂闭合时，它们形成一个平行于引导件的标尺线孔，其尺寸被设计成接收标线。 标线包括其长度上的深度标记，其用于指示用于程序中的固定装置的长度。

    摘要： An internal fixation pin comprises first and second portions with threads of different diameters, but having the same pitch and thread depth. The first portion includes a self-tapping tip. No enlarged head portion is provided to the pin at the end opposite the tip. A non-threaded shaft portion is frangibly connected to the second portion and is a mechanism for rotating the pin for threaded insertion into bone. A plurality of circumferentially spaced-apart longitudinal grooves are provided on the second portion adjacent its intersection with the shaft portion. After insertion of the first and second portions across a fracture, the shaft portion is removed. The grooves permit rotation of the pin for removal should removal be necessary. A driver for pin removal is also provided, as well as a mill tool.

    摘要： An RJ-11 jack, or plug, is described that is self-locking and has a self-ejecting feature. In particular, an RJ-11 jack is constructed with a tang on the rear lower portion of the RJ-11 jack in such a way that the tang is coupled to a locking tab of the RJ-11 jack. When inserted into an RJ-11 receptacle, or housing, the tang is compressed as a result of contact with an inside wall of the RJ-11 receptacle. The locking tab of the RJ-11 jack locks the RJ-11 jack into position with the tang compressed. The RJ-11 jack includes a tool access opening such that a tool, like a small screwdriver, can be inserted to press on a release tab, which is connected to the locking tab. When pressed, the applied force pushes up on the release tab, thereby moving up the locking tab and releasing the RJ-11 jack. The resultant decompression of the tang causes the RJ-11 jack to eject.

    摘要： A surgical device and method used to assist in the surgical repair of damaged and/or severed tendons. In the present invention, the device is comprised of a distal conical member, having an inner and outer surface, a tapered tip, a rounded end, and windowed openings on either side of axial centerline passing through the inner and outer surfaces. In the same embodiment, the device is comprised of a proximal concave convex member with an inner and outer surface, a tapered tip, and a rounded end, tapering both in width and thickness to the tip. The present invention further discloses a method of passing a severed flexor tendon through the tendon sheathing to the repair site aiding in the passage of the severed tendon through the edges of the pulleys in the flexor tendon sheath, wherein the distal conical member of the device disclosed in the present invention is introduced into the edge of a flexor tendon sheath's pulley and a severed tendon end is passed along the inner surface of the conical member allowing the tendon to be reintroduced into the sheathing with minimal trauma. The present invention further discloses a method of dilation of the pulleys in the flexor tendon sheath, wherein the proximal concave convex member of the device disclosed in the present invention is introduced into the edge of a flexor tendon sheath's pulley to a desire depth and left in place until the desired amount of dilation is achieved the tendon is then introduced back into the sheathing utilizing the afore described method.
