Tibial resector guide
First Claim
1. A resector guide for use in orthopaedic surgery to form a stable cutting surface for a surgical saw blade, said resector guide including a head, a cutting guide pivotally carried by said head and including a slot, said cutting guide having a posterior aperture and an anterior aperture forming said slot for accommodating said saw blade, said head further including adjustment means connected to said cutting guide for pivoting said slot in an anterior-posterior direction relative to said head, said head being carried by a rod adapted to position said head adjacent an end of a patient'"'"'s limb, means carried by said head means operatively associated with said rod member for shifting said head in a longitudinal direction relative to said rod member, said rod further including an alignment device carried at an end opposite said head for contacting a second end of said limb.

Abstract
A tibial resector guide having an angularly adjustable head controlled by a thumb actuated slide mechanism. The head may be positioned in a plurality of predetermined angular orientations in the anterior-posterior plane. The cutting head guide includes angled side walls which permit the guide to have a narrow aperture yet allow the saw blade to completely pass through the tibia. Further, the tibial resector of this invention includes a telescoping rod and a length adjustment mechanism adjacent the head for providing small height adjustments for positioning the head. The length adjustment member includes an enlarged thumb wheel to ease operation. A pinning platform is connected to the adjustment member such that it is shiftable with the adjustment member relative to the guide head. The pinning platform permits the surgeon to pin the upper end of the instrument to the patient'"'"'s leg preventing movement of the instrument during resection. After pinning, the head may be further adjusted in height by rotating the adjustment member. The instrument further includes a sliding ankle adjustment to provide proper alignment of the guide with the tibia and femur.
