The present invention relates to a focus control device such as a medical light that makes it possible to easily adjust the position and direction of the plurality of lamps and the depth of focus regardless of the irradiation angle of the lamp.

As a focus control apparatus of the conventional hermetically sealed medical lamp, there exists Japanese Patent No. 973053 (Japanese Patent Office 54-5637) owned by this applicant.

That is, in the hermetic medical lamp, the rotary shaft 26, the bevel gear 27, and the 12 are rotated by rotating the focus adjustment knob 25 provided on the outside of the pipeless attaching pipes 8 and 30. , Ramping the operating rod 22 straight through the gears (19), (32), (33), (36), (37) and screw gears (20), freely rotating the ramp at its fore end. By pressing the abutting plate 21 fixed to the holder 15 to operate, it is possible to adjust the focus F of the plurality of lamps 11 and 13, or to adjust the focus adjusting knob 25 when using this. By rotating, the actuating rod 22 through the rotary shaft 26, bevel gears 27, 12, 19, 32, 33, 36, 37 and screw gear 20 ), It is possible to adjust the depth of focus, but it is difficult to adjust the small depth of focus, that is, fine adjustment. Since the operation is performed by the operation handles provided separately, the operation handles must be operated when a slight movement of the lighting adjustment, lighting, etc., or a change in the irradiation angle is necessary, especially during surgery. The manipulator mechanism is complicated, and in addition, a satisfactory depth control cannot be obtained by the operator, and the depth adjustment must be performed as a focus adjusting knob 25 provided on the side surfaces of the pipes 8 and 30 with the lampless lamp. Therefore, in the case where the shadowless lamp is used inclined, there are disadvantages in that the focusing adjustment is inconvenient, such as being unable to touch the focus adjusting knob 25 or lifting the heel depending on the tilting direction.

In addition, when the number of the lamps 11 and 13 reaches a large number, since the space occupied by these parts and the wheel 12 becomes large on the structure, there was a limit in miniaturization of the focus adjustment mechanism part.

As for the code | symbol in the above, the code | symbol of Japanese special application 54-5637 is used.

On the other hand, for this kind of medical lighting, it is required to be extremely miniaturized in order to prevent the laminar flow from being disturbed, especially when it is installed in a bioclimate with clean air.

The present invention solves the problems in the prior art as described above, and the problems required for recent medical lighting, and as one handle, the movement of the lighting, the change of the lighting direction, and the position adjustment and the depth of focus of the lamp. It is an object of the present invention to provide a focusing apparatus for medical lighting, which can be adjusted and finely adjust them, and enables easy adjustment of the depth of focus irrespective of the direction of inclination of the lighting and miniaturizes the entire lighting as much as possible. It is.

The present invention has a rack at the center of the basket in which the movement of the ceiling, the stand, and the like is freely installed, with the center point interposed therebetween, and the circumferential guide grooves in the radial direction in the plane. The rotating body is configured, and a plurality of lamps are arranged in the radiation direction around the rotating body, and the rotating inclination is freely arranged in the direction of the central axis of the rotating body. In a medical lighting lamp in which one end is inserted and each other end thereof is to be mounted on the movable part of each lamp, a focusing knob is provided on both sides of the opposing basket outside the center of the basket, respectively. Attached to the rotation shaft supported by the basket, and gears engaged with the racks, and below the outside of the basket, so that rotation is free. The gears engaged with the gears engaged to the pair of focusing handles protruding from each other are respectively fixed separately.

Referring to the application of the focusing device and the embodiment of the medical lighting lamp according to the present invention, the hermetic medical lighting lamp according to the drawings as follows.

At the end of the rotation of the cylindrical rotary arm 3, which is freely attached to the ceiling wall 1 by the equivalent attachment hole 2, the cylindrical arm 4 is freely rotated with respect to the rotary arm. At the lower end of the downed arm 4, the U-shaped lamp house support arm 6 is mounted so that the angle change and the rotation are free through the cylindrical automatic balance 5.

On the line connecting the two front ends of the lamp house support arm 6, the lamp house rotational inclination pipes 7 and 8 are installed in a pivot, and the closed basket 9 is fixed in the center thereof. .

It is the end of the angular rotation shafts 10 and 11 which are bent and supported by being inserted into the photocuring body 9 from both ends of the lamp house rotationally inclined pipes 7 and 8, and the lamp house rotationally inclined pipe 7 ), And focusing knobs 12 and 13 are mounted at the outer end portions of (8) and (8).

The lamp 14 is fixed to the center of the photoreceptor 9 by the attachment member 15, and on the circumferential side of the lamp 14, above the rotary shafts 10 and 11, the lower circumferential side A disk-shaped rotary body 19 having a rack 16 and 17 formed thereon and six axial movement guide grooves 18 formed of curved grooves by being inclined in the radial direction at equal intervals on a plane, It is placed on the mount 20 so that rotation is free.

In the radiation direction centering on the photoreceptor 9 from the outside of the photoreceptor 9, the six connection pipes 21 may be provided at equal intervals, including lamp house rotation inclined pipes 7 and 8. Is disposed, and at the end thereof, an egg-shaped closed lamp house 22 as each basket is inclined and fixed at a predetermined position of the center axis of the basket 9 so that their center axes can be coincident with each other.

These connecting pipes 21 are installed above the rotating body 19 in the photoreceptor 9.

In each lamp house 22, the inclination of the lamp 23 is attached freely to the optical axis in the direction of the center axis of the photoreceptor 9.

One end of the universal joint 26 serving as a connecting rod provided on the drive shaft 25 fixed to the rotational inclined shaft 24 of these ramps 23 in the connecting pipe 21 is freely connected to the bowl joint 27. The other end of the universal joint 26 is screwed to the end thereof, and the lower end thereof is pinned to the pin 28 to be moved in the axial movement guide groove 18 of the rotating body 19. It is installed and connected to the rotating body 19 by this.

One side 31 and 32 of the bevel gear are installed in the lower side of the lamp house rotating inclined pipes 7 and 8 so as to be free to rotate, and one side 31 of these bevel gears, (32) is installed so that the rotation is free, and the lower surface of one side (31), (32) of these bevel gears are attached to the focus adjustment handles (29), (30), and beveled freely, and beveled On one side 31, 32 of the gear, the other side 33, 34 of the bevel gear fixed to the rotary shafts 10, 11 are engaged.

The gears 35 and 36 meshing with the racks 16 and 17 of the rotating body 19 are fixed to the front ends of the respective rotary shafts 10 and 11.

As a mechanism for engaging and releasing the focus adjusting handles 29 and 30 with one side 31 and 32 of the bevel gear, the recess groove 37 formed in the lower surface of one side 31 or 32 of the bevel gear is provided. , The projections 38 formed on the upper surfaces of the focusing handles 29 and 30 are inserted and engaged and disengaged as they are pulled out, and at the same time, the circumferential surfaces of the focusing handles 29 and 30 are annular. The engaging groove 39 of the groove is formed, and the front end of the screw 41 to be screwed from both sides of the sleeve 40 is inserted into the groove 39, so that the focus adjusting handle 29, ( 30 is rotatable, but it is used to be configured so that it does not escape from the slive 40.

Referring to the operation of the focus adjustment example of the hermetic medical lighting lamp according to this embodiment is as follows.

First, from the lower openings of the respective sleeves 40, 40 of the lower side of the lamp house rotational inclined pieces 7, 8, a sterilized, sterilized focusing handles 29, 30 are inserted, After the projections 38 of the focusing handles 29 and 30 are engaged with the recesses 37 of the lower surface of the bevel gears 31 and 32, the screw 41 is adjusted to the focusing handle. Screws are lowered in the locking grooves 39 of (29) and (30) to prevent the focusing handles (29) and (30) from falling out of the sleeves (40) and (40).

Therefore, since the focusing handles 29 and 30 are integral with the lamp house rotational inclination pipes 7 and 8, the focusing handles 29 and 30 are moved up, down, front, back, left and right. By moving freely, the focal position of the entire lamps 14, 23 is adjusted.

In addition, by rotating either of the focusing handles 29 and 30, the rotation of the focusing handles 29 and 30 causes the bevel gears 31 to 34 to rotate. 10), (11), gears (35), (36), racks (16), (17), rotor (19) through the axial movement guide grooves (18), pins (28) and universal joints (26). It is converted to linear motion and transmitted to the drive shaft 25 of the lamp 23, so that the depth of focus of the lamp 23 is adjusted.

The depth of focus is adjusted by the bevel gears 31 to 34, the racks 16 and 17, the gear ratios of the gears 35 and 36, the inclination angle of the axial movement guide groove 18, and the like. Therefore, by appropriately setting these, it is possible to finely control the ultra-depth of the lamp 23.

When the use of the hermetic medical lamp is completed, the sleeve 40 slows the screw 41, and the focusing handles 29 and 30 are removed from the sleeve 40 to be sterilized and sterilized. Lose.

In addition, when the focusing handles 29 and 30 are not used or neither of the focusing handles 29 and 30 can be used, the focusing knob of either person other than the operator is used. Using (12) and (13), the same adjustment as that of the depth of focus of the lamp 23 by the focusing handles 29 and 30 can be performed.

That is, when either of the focus adjusting knobs 12 and 13 is rotated, the rotation is performed by the gears 35 and 36 and the racks 16 and 17 and the shaft movement guide groove 18. It is decelerated by the inclination angle and is transmitted to the drive shaft 25 of the lamp 23, so that even in this case, fine adjustment of the depth of focus of the lamp 23 is possible.

Further, when the focusing handles 29 and 30 are rotated, the focusing knobs 12 and 13 are rotated, and when the focusing knobs 12 and 13 are rotated, the focusing handle 29 ) And (30) are rotated, but both following rotations do not affect the focal depth control of the regular lamp 23 at all.

In the above embodiment, it is shown that the basket is made of a rotating body accommodating portion and each one of the plurality of lamps is a basket formed of a separate hermetically sealed type, which is referred to as an open type basket or shown in FIG. As described above, it is natural that the photoreceptor has the same function as the above-described embodiment even if the photoreceptor is formed of the photoreceptor provided in the single photoreceptor 42 as a whole.

Further, for example, the focusing handles 29 and 30 are fixedly mounted on the lamp house rotational inclination pipes 7 and 8, or by the known configuration. It is free to bend so that the lighting does not interfere with lighting, or to set the number of lamphouses 22 to an appropriate number of two or more.

As described above, according to the present invention, only one focusing handle can be used to move the entire lighting, change the irradiation angle, and adjust the depth of focus and fine adjustment thereof, as well as the focusing handle and focusing control. Since the knobs are formed in pairs, the steering wheel or the focus knob can be rotated at the same time as either the handle or the knob can be used to adjust the focus or knob, regardless of the angle of illumination such as eminence. Since the mechanism for converting the motion into a linear motion for the rotational inclination of the lamp is constituted by a gear fixed to a rotating shaft provided in the basket, a rack formed on the rotating body, and a shaft moving guide groove, It can be formed with extremely simple components, and the basket can be made compact so that the bioclean lu It is not only suitable for the luminescent flow which is installed in the luminaire, but also it is suitable to easily set the gear ratio or the inclination angle of the axial movement guide groove to obtain a deceleration effect. Even within the narrow basket, there is an effect that a fine adjustment mechanism of the depth of focus of the lamp can be provided.

In addition, as shown in this embodiment, in the case where the photoreceptor is a single photoreceptor in which the rotating body and the plurality of lamps are housed, in particular in the case of a multi-dimension lampless lamp having six lamps, Since the distance between the lamps can be narrowed, the size of the entire basket is significantly smaller than that of the conventional single basket type multi-dimension lighting system.

In addition, when the connecting rod is a universal joint, it is possible to reliably absorb the complex movement of the connecting rod when the linear movement of the connecting rod is converted into a ramp cloud of the lamp.

Then, in the case where the focusing handle is attached to the lamp house rotational inclination pipe or the collet sieve so that it can be detached freely, by sterilizing it completely, fine adjustment of the irradiation position and the depth of focus of the operator's rough surface, etc. is performed. It has several effects, such as being able to get the best lighting effect.
