Abstract
ABSTRACT OF THE DISCLOSURE
This invention relates to an appliance for correction of spinal curvatures, performed in course of treatment by means of surgical struts.
The appliance has the form of a double-arm lever making it possible to extend the effective length of the strut placed in the patient's body.
One arm of said lever ends with a holder for clamping the hook of the strut, the other arm being provided with a screw adjusting the spacing of the arms and the displacement of the hook along the strut. This other arm is split longitudinally, one limb being provided with a tapped hole wherein said adjusting screw operates, whereas the other limb is provided with a clearance hole, and with a pivot wherein the link mechanism and the pointer of a dynamometer are mounted. The side surface of this other arm carries a scale over which the tip of the pointer travels indicating the value of the force being applied to the operator.

Description
~: ;
This invention relates to an appliance for additional correction of spinal curvatures, being carried out in collrse of treatment by use of surgical struts.
~ There is known a method of correction of spinal curvatures which ; consists in relieving the affected vertebrae by means of a surgical strut placed in the patient's body. The strut preferably has the form of a rod the ends of which are placed in the eyes of hooks fitted between the patient's vertebrae. In order to secure a sultable effective length of the ` strut, one of its ends is provided with several conical steps adapted to fit the upper hook, or, according to the Polish patent 96,695, with grooves perpendicular to the rod axis9 designed to have inserted therein a ring fix-ing the position of the hook and securing it against displacement.
Investigations carried out recently by the surgeons show that after a suitable period of therapy a loosening of vertebrae occurs, making it possible to perform additional correction of the distorted spine by extend- -ing the effective length of the strut. Such extension may be achieved by displacement of the hook engaged at a suitable place on the spine, after ~; previous surgical uncovering of a small operation area.
The aim of the invention is to make it possible to perform such additional correction, and the object of the invention is the design of a simple appliance adapted to displace the hook on the strut and preferably provide simultaneou: determination of the force developed by the resistance of the spine to be straightened.
The invention provides an appIiance for correction of a spinal curvature performed in ~he course of treatment by means of a strut placed in a patient's body, wherein said appliance is p~ovided with two arms connected to each other by means of a pivot joint9 an adjustment screw being located to operate between respective first sections of said arms located on one side of -~
said joint so that when these first~sections approach each other by adjust-ment of said screw opposed second sections of said arms situated in the same plane move away from each other; the second section of one arm terminating in a first jaw which cooperates with a second jaw carried thereon through a '' , ~
pivoted joint~ said jaws carrying confronting pins adapted to be coupled to the strut, the spacing of said jaws being adjustable by means of a second - screw in a plane perpendicular to the plane in which the arms of theappliance pivot, the end of the second section of the other arm having a recess adapted to support the end of the strut.
The pins of the jaws of the holder are placed in holes made in the lateral surface of the hook placed on the strut and protect the jaws against slipping off the hook.
Preferably ~he second section of the second arm is split longitu-dinally and forms two limbs. One limb is provided with a clearance opening and the other is provided with a threaded opening. The adjusting screw which ~;
sets the spacing of the arms passes through both openings. On the limb with the clearance opening a known dynamometer is flxed to a pin and indicates the resisting force of the spine being straightened.
The appliance according to the inven~ion is simple in design and independent in use. Its application enables additional correction of the spinal curvature to be achieved through extending the effective length of the strut placed in the patient's body, and enables an additional relieving . .
of the ill vertebrae The measurement of the resistance force of the spine ;makes it possible to increase the dilatation gradually lmiformly, and in strictly controlled manner, and thus safely.
The invention will be now explained more particularly by means of an exemplary embodiment, with reference to the accompanying drawing, wherein:- Figure 1 is a front view of the appliance according to the invention; Figure 2 is a side view of said appliance; Figure 3 shows a section of one arm; and Figure 4 illustrates the appliance in isometric view.
The appliance iæ designed in form of a lever having especially shaped arms 1 and 2 connected through a pivot joint 3 which divides these arms into sections la, lb, 2a, 2b.
The section la of the arm l is pr~vided at its end on its inner side-with a recess 4, and the section lb has a termination constituting the jaw 5 of the holder. The ja~ 6 forming the other member of the holder is ', .
~ -2-:
mounted on the arm sec~ion lb by means of an articulated joint 7, and is provided with a tapped hole wherein a screw 8 is arranged for the purpose of clamping the jaws S and 6 on a hook 9 of a strut 10 placed in the patient's body. The jaws 5 and 6 are provided on their inner sides with pins 11 securi~g the hook 9 against slipping out of the holder.
The arm section 2a is divided longitudinally into two lim~s, one ; of its limbs being provided with a tapped hole engaged by a screw 12 which operates to adjust the spacing of the arms of the appliance, the other limb ~`
having an aperture with a diameter larger than that of the screw 12 passing therethrough.
; The arm section 2b is provided on its inner side with a recess 13 wherein the end of the strut 10 abuts in the course of performing of an additional dilatation. After displacing the hook 9 along the strut 10 its position is secured by means of the ring 14. The part of arm section 2a having the aperture, is provided with a pivot 15 on which the link mechanism 16 and pointer 17 of a dynamometer is mounted. The tip of the pointer 17 -~ travels over a scale 18 carried on the side surface of the arm section 2a and calibrated according to the value of the resistance force of the spine to be straightened.
