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

* 1.1BEfore I come to the particular kinds of dislocations, I think it not amiss to describe three sorts of bandages, and give you their figures, as those which are most fit to hold and ex∣tend d slocations. 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 DD. Within this there lie hid three wheels, through whose furrows runs the rope which is to be

drawn, marked with this letter H. At the ends of the Pulley are hooks fastned, the one of which is to fasten the Pulley to a Post, the other is to draw the ligature fastned to the part. The Boxes or Cases wherein the Pulley is kept, is marked with BB. Their Covers are marked with AA.

A Screw pin which may be twined, and so fastned to a Post, that so one of the ends of the Pulley may be hooked thereto, is signed with C. A Gimlet (marked by F) to make a hole in a Post, so to let in the Screw pin. You may see all these things exprest in this Figure.

Some Practitioners in stead of this Pulley, make use of this described instrument, which they term Manubrium versatile, or a Hand-vice. The end thereof is fashioned like a Gimlet, and is to be twined into a Post. Within that handle lies a Screw with a hooked end, whereto the string or ligature must be fastned. Now the Screw-rod or Male-screw runs into the Female by twining

about of the handle; and thus the ligature is drawn as much as will suffice, for the setting the di∣slocated bone. Having delivered these things thus in general, now I come to treat of the Luxa∣tions of each part, from the jaw-bone even to the toes of the feet.

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