Abstract
Abstract The specification describes an apparatus comprising a positionable seat group fitted with adjustable shoulder and cervical supports for accomodating and securing a patient below a motorized cervical traction and torsion applying assembly and mechanism. The assembly comprises a stationary structure on which a traction and torsion group is supported at adjustable level. Such group is provided with an adjustably counter-weighted oscillatable arm having one end portion above said seat, and comprise a member supported for rotation about a vertical axis and having hooking bar for connecting an adjustable cervical haulter therebelow. The mechanism comprises means for controllably oscillating said arm for continuous or intermittent traction, and for selectively and alternatively rotating clockand counter clockwise said bar, selectively exerting static and/or dynamic treatments to the patient''s cervical spine and neighbouring body parts.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
151 words
An apparatus adapted for selectively applying both tractive and torsional forces to the cervical region of a patient, the said apparatus comprising in combination, an arm-like member pivotally mounted intermediate its ends about a first horizontal pivot axis, a halter for supporting a patient''s head at the cervical region, a connecting device mounted at one end of the said arm-like member that is oscillatable above the patient''s head on a second pivot axis normal to the said first horizontal pivot axis, the said connecting device including hooks from which the said halter is suspended, a first mechanism for continuously or intermittently oscillating the said connecting device about the second pivot axis so as to apply torsional forces to the patient''s cervical region, and a second mechanism for continuously or intermittently oscillating the arm-like member about the first horizontal pivot axis so as to apply tractive forces to the patient''s cervical region.
Claim 2
Independent Claim
151 words
An apparatus adapted for selectively applying both tractive and torsional forces to the cervical region of a patient, the said apparatus comprising in combination, an arm-like member pivotally mounted intermediate its ends about a first horizontal pivot axis, a halter for supporting a patient''s head at the cervical region, a connecting device mounted at one end of the said arm-like member that is oscillatable above the patient''s head on a second pivot axis normal to the said first horizontal pivot axis, the said connecting device including hooks from which the said halter is suspended, a first mechanism for continuously or intermittently oscillating the said connecting device about the second pivot axis so as to apply torsional forces to the patient''s cervical region, and a second mechanism for continuously or intermittently oscillating the arm-like member about the first horizontal pivot axis so as to apply tractive forces to the patient''s cervical region.
Claim 3
Dependent Claim
58 words
An apparatus as described in claim 1, which includes a movable counterweight mounted in that portion of the arm-like member opposite the connecting device and means for adjusting the said counterweight at a position between the first horizontal pivot axis and the end of the arm-like member so as to control the tractive forces applied to the patient.
Claim 4
Dependent Claim
37 words
An apparatus as defined in claim 1 in which the said second mechanism comprises a motor and actuating means between the said motor and the said arm-like member for oscillating the arm-like member about its pivot axis.
Claim 5
Dependent Claim
91 words
An apparatus as defined in claim 1 in which the second mechanism for continuously or intermittently oscillating the said arm-like member includes a motor, a cam driven by the said motor and cooperative with that portion of the said arm-like member which is located on that side of the first horizontal pivot axis which is opposite to the side on which the connecting device is located, so that the oscillation of the arm-like member with each revolution of the said cam supplies essentially vertical tractive forces to the patient''s cervical region.
Claim 6
Dependent Claim
48 words
An apparatus as defined in claim 1 in which the said first mechanism includes a motor mounted on the said arm-like member and a crank means driven by the said motor and connected to the said connecting device for oscillating the same about the said second pivot axis.
Claim 7
Dependent Claim
32 words
An apparatus as defined in claim 5 and further including means between the said crank means and the said connecting device for adjusting the angle of oscillation of the said connecting device.
Claim 8
Dependent Claim
119 words
An apparatus as defined in cLaim 1 and including first and second motor means for operating said first and second mechanisms, in which the said connecting device is mounted on a shaft extending along the said second pivot axis and including biasing means between the said shaft and the said arm-like member for biasing the said shaft in an upward direction, and switch means connected to the said shaft and in circuit with the said first and second motor means for actuating the same only when, during operation of the said apparatus, a downwardly directed force is applied to the said shaft which is greater than the force applied upwardly by the said bias means to the said shaft.
Claim 9
Dependent Claim
47 words
An apparatus as defined in claim 1 which includes an adjustable seat located below the connecting device, which seat is adjustable relative to the plane in which the arm-like member oscillates, so that the tractive forces are applied to the patient''s cervical region in a preselected direction.
Claim 10
Dependent Claim
118 words
An apparatus as defined in claim 1 in which the halter includes a mandibular pad , an occipital pad, an adjustable intermediate strap connecting the said mandibular and occipital pads, and essentially vertical lateral adjustable straps, each having a lower portion secured to a side portion of one of the said pads and an upper portion attached to means for detachably and selectively connecting the said pads to said connecting device, so that the forces transmitted from the connecting device to the said pads and the patient''s cervical region can be directed in a plurality of different directions for selectively concentrating the tractive forces in a plurality of locations between the mandible and the occiput of the patient.
