Bone shaping instrument and method for using the same

A bone resection tool for resecting an end of a bone along a surface having a curvature comprises a guide, a cutting tool and a track follower. The guide is configured to be removably attached in a fixed position to the end of the bone. The guide is configured to include a track exhibiting a curvature generally corresponding to the curvature of the surface to be resected in the bone. The cutting tool includes a cutting face. The track follower is configured to couple to the cutting tool and cooperate with the track to facilitate reciprocation of the cutting tool relative to the guide to induce the cutting face to resect the bone along the surface having the curvature. A method for cutting a bone along a curved surface conforming to the curvature of a curved surface of the underside of a prosthetic component comprises the steps of incising the tissue surrounding the surface of the bone, positioning a guide alongside the surface of a bone to be cut, affixing the guide to the bone, interconnecting a cutter having a cutting face with the guide, maintaining the cutting face generally parallel to the tangent of the curved surface and traversing the cutting face along the bone while guiding the cutter along the track. The tissue incision incises the tissue surrounding the surface of the bone to be cut in a minimally invasive fashion. The positioned guide includes a track configured to assimilate the curvature of the curved surface of the underside of the prosthetic component.

Observation valve structure

An observation valve structure includes an inlet pipe joint. The inlet pipe joint has an outer threaded section at an inner end thereof, an annular guide groove in the inlet pipe joint, and guide holes at the inner end thereof. The annular guide groove communicates with the guide holes. The inlet pipe joint has a stop trough at the inner end thereof for insertion of an annular gasket. A holder is provided on top of the connector body. The holder has two threaded holes at two sides thereof close to the inlet end of the connector body. A plate is positioned on the holder by two screws which are screwed in the threaded holes. The plate has a top surface with characters which are perpendicular to each other, a position hole disposed close to the middle character, and two apertures disposed at an outer side of the other two characters for insertion of the two screws. The handle has an indication plate. The indication plate has a positioning bead hole for insertion of a positioning bead. Through the right side or the left side of the indication plate limited by the screws or the positioning bead slid into the positioning bead hole and stopped, the handle cooperates with the characters of the plate to control rotation of the ball shutter. Two opposing sides of the ball shutter are airtight through two uniform annular gaskets which can be replaced with ease. The present invention can limit and position the handle and enhance side water flow.
