Definitions
- the present invention relates to a projector for medical use, more particularly surgical, of the type comprising an illuminating dome mounted at articulation around different axes of positioning and orientation and provided, on at least a portion of its widest peripheral contour, of '' a protective tube made of flexible material.
- a projector of this type is described in document FR-A-1,241,989.
- This kind of lighting equipment which overhangs the operating table is adapted to be operated by the surgeon or his operating aids, and this so as to permanently obtain satisfactory lighting of the operating field throughout an operation.
- the illuminating dome of the projector Because of its function, which is to illuminate an operating field, whatever the working position of the surgeon, the illuminating dome of the projector has a large diametrical dimension and, associated with different support arms articulated together, forms a system necessarily bulky.
- the illuminating dome is adapted to be moved by the operator at a height of the order of two meters above ground level, so that it can be, at any time, directly operated by the operator.
- the object of the invention is to facilitate the handling and the adjustment in position of the illuminating dome, without increasing its inertia.
- the protective rod made of flexible material has an internal recess forming a recess and is dimensioned so as to form a gripping member for an operator, for maneuvering the dome.
- the blocking means are controlled by a capacitive effect control circuit comprising sensors arranged in the central handle or a handling hoop.
- the object of the present invention is to make handling and adjustment of the dome position even easier, with an arrangement of low cost, compact, reliable and a great flexibility of use.
- the tube provides the functions of protection against shocks, handling and control of the locking means, by authorizing the use of electrical or pneumatic control means insensitive to the environmental conditions of an operating theater. and whatever the relative positioning of the dome and the operator.
- an operating lighting installation 1 generally comprises a main illuminating dome 2 mounted for rotation F1 around a horizontal axis X1X'1, by a pair of diametrically opposite trunnions -one of which is visible in 3- mounted at the ends of two arms 4 and 5 integral with a fork 6.
- the fork 6 is mounted with articulation along F2 around an axis X2X'2 on an arm with substantially vertical extension 7, itself mounted for rotation along F3 around an axis X3X'3 on a support arm 8 with horizontal extension, which is articulated in rotation along F4 around a vertical axis X4X'4 on a tubular support 9 fixed to the ceiling of an operating room by a circular flange 10.
- annex projector with a dome 16 of more limited dimensions, mounted around an axis Y1Y'1 of a fork-shaped support mounted with articulation to rotate about an axis Y2Y'2 on an arm 17 itself mounted with articulation along the axis Y3Y'3 on an arm 10 articulated along F4 around the axis X4X'4 of the tubular support 9.
- each illuminating dome 2, 16, which has a wide lower edge, is equipped at its periphery with an impact protection flange 22 of flexible material, with an internal profile forming a shoulder annular top 24, an annular central latching groove 25 of the outer edge of the dome 2-16, and a wide annular groove 26 for retaining an optical plate 27.
- the external profile 28 of the protective flange 22 has a convex rounded shape of so as to ensure reception of any impact between the dome 2 (16) and a surrounding object and between the dome 2 and 16.
- This protective flange 22 is hollowed out to form an internal recess 29 to increase its flexibility and facilitate its assembly.
- the flange 22 is dimensioned transversely so as to constitute a gripping member which can be maneuvered by an operator as shown in FIGS. 2, 3 and 4. In this way, it is possible, by simple direct gripping of this flange 22, any desired re-orientation according to the axes X1X'1 (Y1Y'1), X2X'2 (Y2Y'2), X3X'3 (Y3Y'3) and even X4X'4, without requiring maneuvering hoops integral with the dome.
- the recess 29 forms an annular recess and the flexibility of the material constituting the tube 22 and the thickness of its wall 31 of external delimitation are adapted to allow crushing of the tube 22 by simple pressure between thumb and index finger. operator's hand.
- the effect of slight overpressure thus obtained is transferred by a thin tube 32 to a pressure detector 40, coupled to an articulation locking means 41 to ensure the unlocking or the resetting of usual brakes equipping the different articulation (s) (XX ') (YY').
- the signal transfer system of the pressure detector can ensure a permanent excitation of the electromagnets for releasing the articulation brakes during the entire overpressure phase, the disappearance of which causes the electromagnets to be put to rest and the relocking of the brakes, or indeed, the unlocking occurs during a first signal corresponding to a first so-called unlocking overpressure and this until the creation of a second so-called brake relocking overpressure.
- a control means with electrical contacts, for example in the form of two annular conductive pads 33 and 34 fixed at a small mutual spacing on the internal walls of the recess 29 to come into contact under the effect of a slight manual deformation of the flange 22.
- Each annular stud 33 (34) is connected by a conductor 35 (36) and a device transfer to the locking means 41 to provide the latter with a signal for controlling the unlocking-relocking of the articulation brakes.
- a handle 51 for central adjustment of fine adjustment of the illuminating dome 2 (16) is formed as a rigid sleeve 50 which is mounted on a tip protruding axially outward 52 of the support central dome 53 and defining an axial internal recess 54.
- the rigid sleeve 51 is secured in the mounted position by a pawl 63 articulated at 55 and subjected to a locking spring 56 and having an arm 57 whose lowering causes the escape of the ratchet 63.
- a flexible envelope 58 locking by engagement of an end bead 59 beyond a flange 60 of the rigid sleeve 51.
- the present invention applies to the lighting of operating tables, distribution systems in the operating room and intensive care and radiology devices.
