IMPRQVMNT nv SURGICAL INSTRUMENTS FoR THE TREATMgNT oF cLuB-Foo'r.
The Schedule referred 'to in these Letters Patent and making part of the same.
To all whom. it may concern 1 Be it known that I, EMoRx A. GRANT, of Louisville, in the county of J eli'erson and State of Kentucky, have invented a new and improved Surgical Instrument; and I do hereby declare that the following` is a full, clear, and exact description thereof, which will enableothers skilled in the art to make and'use the same, reference being had to the accompanying drawing forming part of this specih'cation, in which- Figure l represents a perspective view of my irn proved surgical instrument.
Figure 2 is a detail side view of the same. A Figure 3 is a bottom view of the same.
Figure 4 is a plan -view of the main part of theinstrument appliedto a human foot, shown in dotted lines as curved before treatment, and in full lines as shaped subsequent thereto.
v Similar lletters of reference indicate corresponding parts.
The object of this invention is to construct an improved vinstrument by which club-feet can be gradually straightened and cured, and the tendons leading thereto properly developed.
' The invention consists in a new construction of rigid shoe, which has a convex side, against which the outer side of the foot is to be held and gradually bent into proper Shape.
Tile invention also consists 1n a new device for holding and retainingr the foot in` said rigid shoe, and -for bracing the entire apparatus from the calf or knee,
all as hereinafter more fully described.
' Ain the drawingreprese'nts the rigid sole of my instrument. This solelis made of sheet metal or other suitable material of the requisite shape, and is attached to a half-shoe, B, made of soft flexible material. Y C is aheel-guard or plate projecting from the hack part of the sole, and made, also, ot' sheet metal or other strong rigid material.
This heel-guard is on the outer side of the shoe continued Ainto a plate, D,-which I intend toterm the resistance-plate. Itis curved so as to. be convex on the inner side, and against this convexfacewill be placed the convex outer side of the crippled foot.
A metallic stirrup-strap, it, may be secured under vthe sole and have .its ends -hent up at the sides of the shoe for: the purpose of bracing the plate D and to y i ends to the sides ot' theshoe, preferablyto the ends ,'aud with the pads I I extending backward to'form .braces for the shoe or plate A. as shown and described.
laced to properly retain the foot within the heel-band.
The toes are then involved in a loop of a rollerbandage, K, which is secured to the sole, and the foot is by the same rmly drawn against the resistanceplate D by winding the bandage around foot and sole.
The plate E is then moved against the foot to prevent the same from overcoming the tension of the bandage.
A strap secured to a button, c, on E, and to a button,1l, on the 4upper part of the inner leg-brace, holds the plate E in place, and serves, also, to elevate the toes and to lengthen the heel-tendon, (tendo Achilles.)
The lower ends of the leg-braces are slotted to tit upon ,buttons4 @that project from the strap a., so that such braces may be readily removed when not needed, especially while the surgeon-is inspecting or arranging the foot. Y'
vWhen the-baud H is buckled and the strap connected with the plate E drawn tight enough, the foot is heldas firmly. as necessary.
The knee-pad is important, as it presses upon the inside of thekn'ee when the same is bent, and thereby turns lthe toesout and prevents them from turning inward. v
. The foot can, on the plate D, he turnedbey'ond its normal line, whereby the contracted tendons arc more readily elongated.
i Both the resistance-plate and the sole being curved, as shown, serve to support every convexityorprojection ofthev deformed foot, and to force the same by gradual, almost imperceptible, pressure, back to its proper form.
Having thus described my invention.,
1 claim as new and desire to secure by -Letters Patent- 1. The rigidlaterally-curved sole A, provided with the heel-band C and the rigidcon've'x resistance-plate D, substantially as 'and for the purpose specified.
2. The plate E, constructed as described, pivoted to the under side ofV the plate A, and arranged with relationto the convex resistauce-plate, D, as shown and described.
A V3. The'leg-braces F, provided with key-hole' slots,
