Abstract
Abstract A portable stand with a removably coupled magnetic surgical tool holder arranged to overlie the patient on an operating cart and present a magnetic purchase for surgical instruments to be held within convenient reach of the operating surgeon. The stand has a flat base plate or platform capable of being engaged beneath the mattress supporting the patient on the operating cart. The holder includes an autoclave sterilizable bar member having a magnetic purchase surface for the surgical instruments canted at about 45* relative to the plane of the mattress so that the tools held thereon are oriented most conveniently relative to the operating surgeon. The distance of the bar member relative to the platform is variable by suitable adjustment means. Means may be provided for varying the angle of the bar member relative to the plane of the table or cart. A modified embodiment of the stand is provided having suitable means for clamping the stand to a veterinary surgical table for veterinary surgery. In this embodiment, means are provided for adjusting the angle of cant of the bar member relative to the table, the head of which usually is lowered about 30* to prevent aspiration in the event the animal being operated should have an emesis.
