Abstract
Abstract A traction bench for treatment of the vertebral column and extremities of the human body comprises a table-like support on which a patient to be treated lies, the support being mounted on a pedestal base with a table support frame and including at least two longitudinally aligned table top sections. At least one of the table top sections, and preferably both, is journalled in the frame for free sliding motion longitudinally of the traction bench, fixation means for securing the patient to the traction bench and the table top sections and their associated frames are also so mounted that they may be displaced laterally relative to one another, and so that each section may also be tilted selectively about a first axis extending transversely of the bench and about a second axis extending longitudinally of the bench. The bench also includes and further includes power traction means of the hydraulic cylinder type for applying a traction force to the patient. The fixation means includes a rod member which is connected to a harness adapted to be applied around the trunk or extremities of the patient and longitudinally adjustably mounted on a retainer bar which is adapted to be secured at substantially freely selectable locations on said table top sections.

Claim 1
Independent Claim
464 words
A traction bench for the treatment of the vertebral column and extremities of a human body comprising a table on which a patient to be treated may lie, said table comprising a pair of elongated separate table sections disposed in spaced longitudinally aligned relation to one another, support means attached to at least one of said table sections for mounting said one table section in a manner permitting said one table section to be displaced relative to the other of said table sections in any selected one or more of four different movements, said support means including first means supporting said one table section for translational movement longitudinally relative to said other table section along a first translational axis parallel to the longitudinal axis of said elongated one table section, second means supporting said one table section for translational movement transversely relative to said other table section along a second translational axis that is oriented at right angles to said first translational axis, third means supporting said one table section for tilting movement in a first angular direction relative to said other table section to tilt the plane of said one table section relative to the plane of said other table sections about a first pivotal axis which extends transversely to the direction of elongation of said one table section, and fourth means supporting said one table section for further tilting movement in a second angular direction transverse to said first angular direction to tilt the plane of said one table section transversely relative to the plane of said other table section about a second pivotal axis which extends parallel to the direction of elongation of said one table section, and fixation means on each of said table sections for fixedly securing one portion of the patient's body to one of said table sections and for fixedly securing another portion of the patient's body to the other of said table sections, said fixation means comprising a mounting structure which is adapted to be selectively moved to any one of a plurality of positions on the surface of its associated table section, means for securely attaching said mounting structure to the surface of said table section at the selected position on said surface, and a harness attached to said mounting structure for engagement with a portion of the patient's body adjacent said selected position on the surface of said table section, said mounting structure comprising a circular disc having an elongated bar extending across the diameter thereof, said disc being adapted to be attached to the selected position on the surface of said table section with said bar oriented in any selected one of a plurality of possible directions relative to the side edges of said table section, said harness being attached to said bar.
Claim 2
Dependent Claim
464 words
A traction bench for the treatment of the vertebral column and extremities of a human body comprising a table on which a patient to be treated may lie, said table comprising a pair of elongated separate table sections disposed in spaced longitudinally aligned relation to one another, support means attached to at least one of said table sections for mounting said one table section in a manner permitting said one table section to be displaced relative to the other of said table sections in any selected one or more of four different movements, said support means including first means supporting said one table section for translational movement longitudinally relative to said other table section along a first translational axis parallel to the longitudinal axis of said elongated one table section, second means supporting said one table section for translational movement transversely relative to said other table section along a second translational axis that is oriented at right angles to said first translational axis, third means supporting said one table section for tilting movement in a first angular direction relative to said other table section to tilt the plane of said one table section relative to the plane of said other table sections about a first pivotal axis which extends transversely to the direction of elongation of said one table section, and fourth means supporting said one table section for further tilting movement in a second angular direction transverse to said first angular direction to tilt the plane of said one table section transversely relative to the plane of said other table section about a second pivotal axis which extends parallel to the direction of elongation of said one table section, and fixation means on each of said table sections for fixedly securing one portion of the patient's body to one of said table sections and for fixedly securing another portion of the patient's body to the other of said table sections, said fixation means comprising a mounting structure which is adapted to be selectively moved to any one of a plurality of positions on the surface of its associated table section, means for securely attaching said mounting structure to the surface of said table section at the selected position on said surface, and a harness attached to said mounting structure for engagement with a portion of the patient's body adjacent said selected position on the surface of said table section, said mounting structure comprising a circular disc having an elongated bar extending across the diameter thereof, said disc being adapted to be attached to the selected position on the surface of said table section with said bar oriented in any selected one of a plurality of possible directions relative to the side edges of said table section, said harness being attached to said bar.
Claim 3
Dependent Claim
112 words
The traction bench of claim 1 including a plurality of modular pad sections adapted to be removably attached to the upper surface of said table section, the shapes and dimensions of said modular pad sections being selected to permit first ones of said pad sections to be disposed in overlying relation to portions of said circular disc in closely adjacent non-covering relation to said bar, and to permit other ones of said pad sections to be juxtaposed in closely adjacent relation to one another and to said first ones of said pad sections thereby to substantially completely cover at least those portions of said table section on which a patient's body lies.
Claim 4
Dependent Claim
266 words
