The present invention provides a tool for inserting a fiducial marker. It comprises a housing and guide assembly, an obturator assembly, a drill for forming a bore hole at an implantation site, and a marker inserter for inserting a marker into the bore hole. The housing and guide assembly comprise a cylindrical housing having a bore provided therein, and a guide tube that is disposed and shiftable within the bore of the housing. The obturator assembly, drill and marker inserter are insertable in the distal end of the guide tube and shiftable therein.

A microscope attachment assembly for mounting a portable surgical laser directly to a surgical microscope to permit the laser to be rotated with respect to the optical axis of the microscope to various physical positions so that if the position of laser obstructs visual or physical axis to the surgical site it may be quickly and conveniently moved with a minimum risk of misalignment.

A cranial perforator with an internal clutch which is engaged when the drill is placed against a bone surface for drilling and which will automatically release when the drill penetrates the skull. The components of the drill are held together by a plastic sleeve and a retaining ring which is ultrasonically welded to the interior surface of the plastic sleeve.

An applicator by which small, discrete, uniform quantities of molten thermoplastic adhesive can be dispensed in rapid succession comprises a body having a heated inlet chamber, which hot melt enters under low pressure, and a pump chamber. A plunger in the pump chamber is reciprocated by a pneumatic motor. A charging stroke of the plunger draws hot melt out of the inlet chamber, across a check valve and into the pump chamber. The discharging stroke expels the hot melt across an outlet check valve and through an outlet orifice coaxial with the pump chamber.
