A machine for forming threads in a cylindrical bone dowel made of bone material, comprising a planar surfaced base provided with a threaded guide member having an externally threaded portion. A holding and rotating assembly is mounted on the base to rotatably hold the bone dowel so that the central axis of the bone dowel extends in the axial direction of the threaded guide member, An essentially planar support member is mounted on the guide member for movement with respect to base and an angle adjustment assembly is mounted to the support member. A cutting assembly having a cutting member in the form of a burr is also mounted on the support member so that when the threaded guide member is rotated the cutting assembly and associated cutting member is carried by support member to engage the bone dowel. A timing assembly is connected to the threaded guide member and the holding and rotating assembly so that when the cutting member moves along the bone dowel in an axial direction, the holding and rotating assembly rotates the bone dowel allowing a thread of a predetermined depth and configuration to be cut into the bone dowel.

A rigid or semi-rigid reinforcement member is inserted into or over the damaged portion of an injured tendon or ligament. The tendon or ligament is connected to the reinforcement member such that the cord-member combination can immediately withstand normal tensile forces. The interconnection can be mechanical, such as by pins extending through the sleeve reinforcement member and cord. The sleeve can be bioabsorbable over a sufficiently long period of time that the cord is healed by the time the sleeve is absorbed.

The present invention is directed toward an external drive with a plurality of removably mounted disposable surgical hand cutting assemblies including a housing control unit with a plurality of motors, each of the motors being capable of driving each surgical hand cutting assembly at a different range of rotational speeds. One disposable surgical hand cutting assembly is capable of debriding soft tissue at a first speed and high torque, and a second disposable hand cutting assembly is capable of debriding hard tissue at a second higher speed. A plurality of flexible shafts for transmitting the torsional force from a selected motor to a selected surgical hand cutting assembly provided with a quick connect mechanism disposed on the end of each flexible shaft to quickly connect the surgical hand cutting assembly to one of the motors.

A surgical knot pusher for pushing a suture knot along a suture strand, comprising an elongated tube with a flattened tip formed on the distal end of the elongated tube. The flattened tip is provided with opposing resilient jaws defining a slot therebetween which leads to an eyelet defined by the flattened tip for containing an advancing length of the suture while the suture knot is being pushed allowing the suture strand to easily enter the eyelet while preventing the suture strand from exiting the eyelet. A cutting assembly is slidably mounted within the elongated tube and comprises a rod with a blade having a straight linear edge mounted on one end and a handle on the other end. The blade is biased away from the flattened tip by a spring mounted on the rod, the spring engaging the flattened tip when the blade is moved toward the eyelet by pushing the handle toward the tip.
