Description
- This invention relates to viewing systems and more particularly to a ceiling mounted rotational arm system including a closed circuit television viewing arrangement which is ideal for use in an operating room.
- A typical operating room includes a patient supporting table positioned beneath ceiling mounted illumination. In many instances a modern operating room will also include a closed circuit television viewing system. Cameras for such systems are positioned to provide live television images of surgical procedures as they progress.
- Output signals developed by such cameras are transmitted to monitors in the operating room for viewing by members of a surgical team. The output signals may also be transmitted to monitors in remote locations to enable persons not in the operating room to observe surgical procedures. Thus, the monitors may be viewed by those performing and assisting the surgery and others as well. Indeed with many modern day surgical procedures where TV cameras are inserted into patients such monitors often provide the only images of the surgery that the surgeon can observe.
- It has been proposed that TV monitors in an operating room be supported by ceiling mounts. The stiffness of coaxial cables transmitting image producing signals to suspended monitors is such that it has heretofore been impossible to provide a ceiling supported arm carrying a monitor while providing a suitable range of adjustment to permit other than minimal repositioning of the monitor. Accordingly it would be desirable to provide a ceiling mounted support for a TV monitor which support is adjustable over a range of adjustment to permit the monitor to be repositioned from time to time.
- An adjustable ceiling mounted support for a TV monitor embodies the present invention. The support includes a tubular arm having a mounting end section. The mounting section, when in use, has a through passage mounted with its axis vertical. A tubular arm extends horizontally when in use, from the mounting section. The arm defines a horizontal internal passage in communication with the mounting section passage. The tubular arm includes a 90 degree bend at a location remote from the mounting section. A further tubular arm is suspended from the support arm to in turn support the TV monitor.
- A tubular pulley or sheave including a helical, perimetral groove is coaxially mounted in the mounting section. A coaxial cable extends downwardly from the ceiling into a pulley bore and thence through a wall of the helical pulley to the helical groove formed in the perimeter of the pulley. The cable is wrapped around the pulley in the helical groove. The extent to which the cable is wrapped in the groove depends on the orientation of the support as the support assembly is rotated around the vertical axis while the pulley or sheave is maintained stationary. The inside diameter of the mounting section and the diameter of the pulley are sized to coact in maintaining the cable snugly in the groove. This coaction assures appropriate pay out and pick up of the cable relative to the pulley as the arm and mounting section are rotated around the vertical axis and the stationary sheave.
- The coax cable extends through the tubular arm to a coiled section of the cable positioned in or near the bend. In use if the support arm is rotated about the vertical axis of the mounting section stretching or contraction of the coiled sections occurs. As the stretching or contraction occurs, coaction of the sheave, the mounting section and the cable cause the cable to be fed out from or further wrapped in, the helical groove. Thus, the novel construction accommodates TV monitor repositioning over a range that has not been available in prior monitor supporting arrangements.
- Accordingly the objects of the invention are to provide a novel and improved TV monitor support especially suited for use in a surgical environment and a process of positioning a monitor.
- In the drawings:
- FIG. 1 is a somewhat schematic view showing an operating table very schematically and a ceiling mounted illumination and television arrangement;
- FIG. 2 is a perspective view on an enlarged scale of a helical pulley or sheave made in accordance with the present invention;
- FIG. 3 is a sectional view of the mounting apparatus of the present invention as seen from a vertical plane through the ceiling mount of FIG. 1; and,
- FIG. 4 is a foreshortened and somewhat fragmentary sectional view as seen from a plane normal to the plane of FIG. 3.
- Referring now to the drawings and to FIG. 1 in particular, an operating table is shown very schematically at10. The table is mounted on a
floor 12 of an operating room. A ceiling mountedassembly 14 is suspended from aceiling 15 above the table 10. Theassembly 14 includes an articulated pair oflamp arms 16 supporting alamp 18. The lamp arms are adjustably connected by a pivot at 20. An upper one of thearms 16 includes anend section 22 mounted for rotation about a vertical axis of a vertically suspendedsupport tube 23, FIG. 3 . - A TV camera mounting is shown at24 below the
lamp arm mounting 22. Themountings mounting 24, like themounting 22 is rotatable about the samevertical support tube 23 and axis. Thecamera mounting 24 supports an articulated pair ofarms 25 which in turn support aTV camera 26. The TV camera is positioned to image an operation being performed on the table 10 and to provide output signals for a closed circuit television system. - A pair of monitor support arms are shown generally at28 & 29. For simplicity and clarity of description only the
support arm 28 will be described in detail it being understood thesupport arm 29 corresponds to thesupport arm 28. Thesupport arm 28 includes a tubularend mounting section 30. Theend mounting section 30 is axially aligned with themountings lamp arms 16 and theTV camera arms 25. Themounting section 30 is rotatably supported on thesupport tube 23 by a bearing 31, FIG. 3. - The
support arm 28 includes atubular portion 32 extending horizontally from themounting section 30. Thetubular portion 32 includes a 90degree bend 34 remote from themounting section 30. Afurther arm 35 is pivotally mounted at 36 to an end of thetubular portion 32 remote from themounting section 30. A flat panel monitor is shown schematically at 38. The monitor is suspended from thefurther arm 35 by asupport arm 39 in the shape of an inverted question mark. - Referring now to FIGS. 3 and 4, the novel features of the present invention which permit substantial repositioning of the monitor38 are shown. The assembly includes a
coaxial cable 40 which provides imaging signals to the monitor 38. For clarity of illustration the conductors for providing power to thelamp 18 and for transmitting pick up signals from theTV camera 26 to processing circuitry are not shown. The camera signals which are transmitted to processing circuitry cause the circuitry to in turn transmit imaging signals through thecoaxial cable 40. Thecoaxial cable 40 has substantial stiffness with the result that there has been extremely limited adjustability available in prior supports. Indeed prior systems can be said to be unadjustable. - With the present invention a novel pulley or
sheave 42 is provided and best seen in FIG. 2. Thepulley 42 includes a throughaxial bore 44. Thepulley 42 also includes a perimetralhelical groove 46. The pulley bore 44 communicates with thegroove 46 through aradial opening 48. Thecable 40 extends through the bore of theend mounting section 22 into the pulley bore 44 thence through theopening 48 into thehelical groove 46. The cable then extends through aside opening 50 in theend section 30 to the bore within thetubular portion 32 of thearm 28. As is best seen in FIG. 3, a pin 51 connects thesheave 42 to thesupport tube 23 so that the mountingsection 30 may be rotated around and relative to thesheave 42. - The
cable 40 includes a coiledsection 52, FIGS. 3 and 4. As the support for the monitor is rotated about the vertical axis of the mountingsection 30 and/or adjusted up and down, the coiled section is expanded and contracted depending on the direction of adjustments and the cable is either played out from or further wound into thehelical groove 46. The coiled section of the cable is designed to take up slack in the cable, as it is wound and unwound about the helical cuts in the sheave. The stiffness of the cable, as it is fed from or wound onto thesheave 42 causes the cord to wrap in and out of the helical grooves. The close surrounding fit of the mountingsection 30 about the sheave and the cable is an important factor in controlling the effective length of the cable. Further at least that portion of the cable which does or may engage the internal wall of the mountingsection 30 is equipped with a slippery surface in the form of a wrap of Nylon expandable sleeving. - The described system provides significant adjustability not available in prior systems. For example, in tests of a prototype system a support arm corresponding to the
arm 28, adjustment of 540 degrees of rotation was available. Thus if, for example, the table is repositioned or a new table 10 is installed, substantial readjustment of the positioning of the monitor 38 may be required and the system of the present invention will accommodate such repositioning. - A cathode ray tube type monitor54 monitor is also shown in FIG. 1. The CRT monitor 54 is carried by a
further arm 56 and asupport tray 58. Thefurther arm 56 is pivotally supported by themonitor support arm 29. In practice, one, two or more monitors may be ceiling mounted. Each monitor may be either a flat panel or a CRT type although the panel type monitors are preferred because they are more compact and lighter in weight. - Although the invention has been described in its preferred form with a certain degree of particularity, it is understood that the present disclosure of the preferred form has been made only by way of example and that numerous changes in the details of construction, operation and the combination and arrangement of parts may be resorted to without departing from the spirit and the scope of the invention as hereinafter claimed.
