I, EDMUND GEORGE KENDALL, of 53, High Street, Harborne, in the County of
Warwick, Architect, do hereby declare the nature of my said invention to be as
follows:-
My invention has for its object an improved surgical tool or device for manipu-
lating and cutting plaster or other casings used in surgery for binding up bodies
or limbs which enables the operator to make a cut in the plaster mould from
end to end or to take out sections from a mould without shaking or interfering
generally with the comfort of the patient.
My new tool or device consists in a curved cutter having teeth upon its edge
which may be sharpened or set as required. The circular or curved. cutter is
mounted in a suitable handle slotted out to receive it and may be there rivetted
or secured adjustably with set screws so as to project from the handle any desired
or convenient distance as the handle acts as a guide on each side the saw blade
to determine the distance or depth of the cut and to ensure that the cutter will
not pass through or more than through the plaster or other casing. The form
of the handle may be varied to suit the fancy or convenience of the operator
and the tool may be made with a fast handle with guide pieces set upon the
blade or other portion of the tool to regulate the depth of the cut.

An Improved-Surgical Tool or Device for Manipulating and Cutting
Plaster or other Casings used in Surgery for Binding up Bodies
or Limbs.
I, EDMUND GEORGE KENDALL, of 53, High Street, Harborne, in the County of
Warwick, Architect, do hereby declare the nature of my said invention and in what

manner the same is to be performed to be particularly described and ascertained
in and by the following statement:-
My invention has for its object an improved surgical tool or device for manipu-
lating and cutting. plaster or other casings used in surgery for binding up bodies
or limbs which enables the operator to make a cut in the plaster mould from
end to end or to take out sections from a mould without shaking or interfering
generally with the comfort of the patient.
My new tool or device consists, in a curved cutter having teeth upon its edge
which may be sharpened or set as required. The circular or curved cutter is
mounted in a suitable handle slotted out to receive it and may be there riveted
or secured adjustably with set screws so as to project from the handle any desired
or convenient distance as the handle acts as a guide on each side of the saw blade
to determine the distance or depth of the cut and to ensure that the cutter will
not pass through or more than through the plaster or other casing. The form
of the handle may be varied to suit the fancy or convenience of the operator
and the tool may be made with a fast handle with guide pieces set upon the
blade or other portion of the tool to regulate the depth of the cut.
In order that my invention may be more clearly understood and easily carried
into practical effect I have appended hereunto a double sized sheet of drawings
upon which I have illustrated examples of my improved surgical tool.
Figure 1 is a perspective view shewing my surgical tool fitted in a case of
box D.
Figure 2 is a perspective view of the tool complete.
Figure 3 is a perspective view of the cutter or saw blade detached from the
handle.
In carrying my invention into practice I form the curved cutter or saw A
having teeth upon its edge which may be sharpened or set as required. This
circular or curved cutter or saw A is mounted in the handle B which is slotted
out on its edge to receive it. The cutter or saw blade is then fixed into the slot
in this handle by the rivets a¹ in such a position as to project only a short dis-
tance from the handle at one end and gradually increasing towards the other end
as clearly shewn at Figures 1 and 2 so that the cut may be varied in depth by
using different parts of the blade. Or the cutter or saw A may be secured adjust-
ably into the slot in the handle by set screws or by other means so as to regulate
the distance it projects from the handle. The edges 61 of the handle on each
side of the saw blade act as guides to determine the distance or depth of the cut
and to ensure that the cutter or blade will not pass through or more than through
the plaster or other casing. The form of the handle B may be varied to suit the
fancy or convenience of the operator the recesses which are formed on either side
of the handle being formed so as to obtain a better grip. Instead of using the
edges 61 of the handle as guides for regulating the depth of the cut the blade or
saw may be fixed in a handle and have independent guide piece fixed on the
blade for regulating the depth of the cut.
By using my saw a bandage or casing may be taken off the limb without being
destroyed and replaced if necessary thus enabling a splice to be taken out to
contract the bandage or a piece may be let in to expand it in any part of the
bandage. My tool or device will be found to be very useful and when fitted into
the case or box D) will be found compact and portable.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-

page_text: into a handle or guard such as B in the manner and for the purpose substantially
as herein set forth and as shewn upon the accompanying sheet of drawings.
