    摘要： The present invention relates to a surgical tool for use in knee arthroplasty. The tool is designed to assist a surgeon to implant a knee prosthesis which will be stable when the knee is in flexion and in extension. The tool comprises a parallel pair of paddle flanges adapted for insertion into the flexion or extension gap located between resected surfaces of a proximal tibia and a corresponding distal femur. The paddle flanges are incrementally movable relative to each other to define a range of gaps extending between a minimum gap and a maximum gap between exterior surfaces thereof. The incremental movement is provided by a racked member on which one of the paddle flanges is mounted, the racked member being movable by hand operable means connected thereto and which racked member engages with a pawl to prevent movement thereof in a gap-decreasing direction when the tool is in use.

    摘要： A lancet device includes a main body in which is located a lancet drive shaft 20 having a lancet holder 22 at its front end. A front housing flap 12 is hinged to the front of the main body portion and opens to allow insertion/withdrawal of a lancet. A multi-function cocking/ejection element 16 is operable both to cock the drive shaft prior to firing and to eject a lancet from the lancet holder after firing. The cock/eject element also unlatches the front flap 12.

    摘要： A lancing device includes a main housing 28 having in the forward upper end thereof a loading bay for receiving a capped lancet 12/20. The loading bay is closed by a cover 34 which is pivotally and slideably moveable in the housing. Closing the cover and then pushing it rearwardly causes the lancet body 12 to be pulled rearwardly clear of the cap 20 thereby exposing the lancet needle. Further rearward movement of the shifts the lancet cover into a battery position ready to be driven forwardly by a drive mechanism when fired.

    摘要： An alignment guide for use in femoral head surgery. The guide includes a support arm and a cannulated rod supported by, and adjustable with respect to, the support arm. The guide also includes two jaws. The jaws include a superior jaw and an inferior jaw. Each jaw has a proximal end connected to the support arm and a distal end for clamping to the neck of the femur in use. At least one of the jaws is movable from a first open position to a second clamping position. A toothed block is located on the inferior jaw as a biting element on the inferior jaw to improve, in use, the clamping of the jaw with the neck of the femur.

    摘要： A tibial prosthesis has a metal tray component (1) comprising a transverse member (3) with a peripheral upstanding rim (6) and a projecting stem (4). The upstanding rim (6) includes a posterior rim portion with an undercut lip forming a pair of recesses (7, 8) and an anterior rim portion with an open angled posterior surface portion (9) and a posteriorly projecting barbed portion (10). The prosthesis also includes a tibia insert (2) made of a plastics material which fits on the tibial implant (1) within the upstanding rim (6) and has on a posterior portion thereof a shaped contour (14, 15) adapted in use to fit snugly under the undercut lip and on an anterior portion thereof an anterior surface (13) having a taper angle substantially corresponding to the angle of the open angled posterior surface portion.

    摘要： A catheter placement unit comprises a catheter having an axial bore, a catheter hub at one end of the catheter, an introducing needle having a pointed tip for introducing the catheter into a desired position in a patient's body, and a needle hub on the needle remote from the tip for mounting the needle so that it extends through the catheter bore for introduction of the catheter into the patient's body and so that it can subsequently be withdrawn from the catheter bore leaving the catheter in position in the patient's body. The unit includes a needle tip protector on the needle for shielding the needle tip when the needle has been withdrawn from the catheter bore. The needle tip protector includes a locking device which is initially in an unlocked position permitting withdrawal of the needle from the catheter bore but which is arranged to be placed in a locked position, in which the locking device engages the outer surface of the needle, by withdrawal of the needle from the catheter bore so as to lock the needle tip protector on the needle in the shielding position. The locking device retains the catheter hub on the needle when the locking device is in the unlocked position and releases the catheter hub from the needle when the locking device is in the locked position. Separation of the catheter from the needle is therefore prevented until the needle has been withdrawn from the catheter bore to trigger shielding of the needle tip.

    摘要翻译： 导管放置单元包括具有轴向孔的导管，在导管的一端的导管座，具有用于将导管引入患者体内所需位置的尖端的引入针，以及针远离的针座 从用于安装针的尖端使得其延伸穿过导管孔以将导管引入患者体内，并且使得其随后可以从导管孔中取出，使得导管在患者体内保持就位。 该单元包括针头上的针尖保护器，用于当针已经从导管孔中取出时用于屏蔽针尖。 针尖保护器包括锁定装置，该锁定装置最初处于解锁位置，允许针头从导管孔中取出，但被布置成被放置在锁定位置，锁定装置通过该锁定位置与针的外表面接合，锁定装置通过 将针从导管孔中取出，以将针头保护器锁定在屏蔽位置上的针上。 当锁定装置处于解锁位置时，当锁定装置处于锁定位置时，锁定装置将导管套管保持在针上。 因此，可以防止导管与针头的分离，直到针已经从导管孔中取出来触发针尖的屏蔽。
