Abstract
A two piece construction disposable carpal tunnel ligament tome is provided. In a preferred embodiment the tome has a handle, stem, cutting head with two forward extending and parallel spaced upper and lower forks. The handle, stem, cutting head and forks are injection molded as one plastic piece. Mounted in the cutting head is a blade fabricated from flat stock metal with a forward facing cutting edge concealed by the forks. Extending forward from the blade are upper and lower fork reinforcement members. The fork reinforcements are encapsulated by the molded upper and lower forks. The inventive carpal tunnel ligament tome provides very rigid forks, yet does not require the extensive machining required by tomes with metal forks. Since the blade and fork reinforcement can be fabricated from a flat stock material, fabrication costs can be lowered with extremely high performance of the tome being maintained.
