Technical adjuncts in neurosurgery.

Modifications of several surgical adjuncts are presented: a balanced microscope stand with mouthpiece and hand controls, a piston release operating stool, a support device for resting the surgeon's arms, a table mounted arm with coupling head for attaching self-retaining brain retractors, fish hook retractors, suction tubes, bipolar forceps, aneurysm clips and mobile tip mirrors. Although many of these changes are minor, they considerably facilitate microneurosurgical procedures.
