Cement restrictor for a medullary canal

An expandable cement restrictor comprises an inner member (2) nested within an outer member (1). The members (1, 2) are each formed from a plurality of longitudinal segments (3, 4) which in a non-expanded state are positioned very close to if not touching one another. The restrictor further comprises an expansion body (5) which is positionable within the inner member (2). The restrictor is placed in a medullary canal, and once it has been located in an appropriate position, the expansion body is pulled into the nested inner and outer members (1, 2) to cause the expandable body to dig into the bone of the canal and hold the restrictor in position. A lug on the inner member engages a recess in the outer member to prevent relative rotation of the members. When expanded the longitudinal segments (3, 4) of the inner and outer members overlap circumferentially. ...

Actuation handle utilising a double scissor hinge

The present invention relates to an actuation grip 1 for a microsurgical instrument having an inner shank 16 axially movable relative to an outer shank 15. Two grip parts 11, each with two ends 111, 112, are coupled pivotably at a proximal end 1' of the actuation grip 1. Each grip part 11 is articulated to a first lever pair 12 between the ends of the grip part 11. The first levers 12 are coupled rotatably at an intersection pin 124, and their ends 121, 123 are also connected rotatably to the ends of a second lever pair 13, the second levers being coupled to each other at the other end at common pin 14. Pin 14 is attached to a shank wall, preferably the inner shank. A double scissor hinge or parallelogram linkage is thus formed, which serves to move the two shanks 15, 16 relative to each other when the handles are actuated. Rollers (125, see figure 3) may be mounted on the protruding ends of pin 124 and restrained within slot 161 in the inner shank. The actuator may be locked in a particular ...

Mechanisms for connecting a handle to a surgical instrument

A surgical instrument 4 is a coaxial arrangement of an inner shaft 14 and an outer sleeve 12 with grasping forceps or a cutting tool at the distal end 6. The proximal end of the instrument can be attached to an operating handle 2 by one of two locking mechanisms. In the first, a relief 24 is cut into the proximal end of the inner shaft and can be engaged by translation of a keyhole shaped element (38, figure 3) in the handle in the plane perpendicular to the axis of the instrument. In the second, a hole is bored through the outer tube and receives a pin (46, figure 4) mounted in the handle. Preferably, the locking elements are biased by a spring into their locked positions and a release lever is used to permit attachment or removal of the instrument from the handle.
