CHAP. VII. The description of certaine engines, serving for the restoring of Dislocations.

BEfore I come to the particular kinds of Dislocations, I thinke it not amisse to describe three sorts of Bandages, and give you their figures, * 1.1 as those which are most fit to hold and extend Dislocations. The first Ligature, designed by this letter A, is made for holding the member. The second, marked with the letter B, is fit for drawing or extension, and consists of one knot. The third, whereto the letter C is put, consisting of two knots, is to hold or binde more straitly.

The delineation of the three Ligatures.

I have thought good also to delineate the following Engine, made for to draw and extend more powerfully, when the hand will not serve. It is made like a Pulley, marked with these letters D D. Within this there lye hid three wheeles, through whose furrowes runnes the rope which is to be drawne, marked with this letter H. At the ends of the Pulley are hooks fastened, the one of which is to fasten the Pul∣ley to a Poste, the other is to draw the ligature fastened to the part. The Boxes or Cases wherein the Pulley is kept, is maked with B B. Their covers are marked with A A. A screw pin which may be twined, and so fastened to a Poste, that so one of the ends of the Pulley may be hooked thereto, is signed with C. A Gim∣let

(marked by F.) to make a hole in a Poste, so to let in the screw pin. You may see all these things exprest in this following figure.

A Pulley.

Some Practitioners in stead of this Pulley make use of the hereafter described Instrument, which they terme Manubrium versatile, or a Hand-vice. The end ther∣of is fashioned like a Gimblet, and is to be twined into a Poste. Within that han∣dle lyes a screw with a hooked end, whereto the string or ligature must be fastened. Now the screw-rod or male-screw runnes into the female by the twining about of the handle: and thus the ligature is drawne as much as will suffice, for the setting the dislocated bone.

Manubrium versatile, or, A Hand-vice.

Having delivered these things thus in generall, now I come to treate of the Luxations of each part, from the Jaw-bone even to the toes of the feet.

Notes

• * 1.1

  These ligatures are not for de∣ligation, but extension.
