Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a medical surgical light, particularly a medical surgical light suitably used for dentistry, obstetrics and gynecology, and urology.

[0002]

[Prior art]

 In treatments such as dentistry, obstetrics and gynecology, and urology, medical surgical lights are used to illuminate the treatment site and the working area of the operator. This medical surgical light does not interfere with the operation or work even if a surgical instrument or a surgeon's hand enters the optical path between the surgical light and the illuminated part. In general, light from a single light source is reflected by a reflector composed of a plurality of small reflecting mirrors having different reflection positions and reflection angles, and the reflected light is used. , Causing the effect of an operating light.

[0003] In such a medical surgical light, the light reflected by a reflecting mirror and illuminating the illuminated part has conventionally been formed into an elliptical shape or a rectangular shape due to a request for the shape of the illuminated part. The condensed irradiation area is shaped so as to form a condensed irradiation area, that is, the condensed irradiation area that illuminates the illumination site brightly has an elliptical or rectangular shape. This is because, for example, when illuminating the oral cavity of a patient in dental treatment, a simple circular condensed irradiation area can be used. In order to provide the light, the condensing irradiation area is made into an elliptical shape, and the elliptical axis is illuminated so as to cross the oral cavity in the lateral direction of the face so that the irradiation light does not enter the patient's eyes. This is because the vicinity of the oral cavity can be irradiated so as to be suitable for the operation.

[0004] However, the medical surgical lamps conventionally used are made for respective purposes, and the direction of the elliptical axis of the condensed irradiation area such as the elliptical shape is also in principle. It was fixed to. In this case, the direction of the elliptical axis of the fixed focused irradiation area, that is, the direction of the focused irradiation area could not be changed. FIGS. 7A and 7B show another example of a conventional medical surgical light.

The medical surgical light 20 has a light source (not shown) and a reflecting mirror (not shown) integrated with a surgical light 20 fixed to a frame 23, and the frame 23 is provided with a multi-joint free arm. The frame 23 is provided with an operation handle 23b so as to be rotatable by rotation support means 24a. As shown in FIG. 7 (b), by operating the handle 23b, the frame 23 to which the surgical light 20 is fixed is rotated with respect to the free arm. In addition, the direction of the converging irradiation area of the surgical light can be rotated.

In this device, the direction of the condensed irradiation area of the surgical light can be changed in accordance with the situation of the illuminated spot. As shown in the figure, the shadowless light comprising a light source, a reflector, and a frame 23 is used. In order to rotate the entire lamp 20 with respect to the free arm 24, the mass of the rotating portion is large. When the handle is operated by a handle, a considerable force is required, and the lamp 20 is frequently rotated. Was quite inconvenient.

FIGS. 8A and 8B show still another example of a conventional medical surgical light. In this medical surgical light 30, a large number of small reflecting mirror surfaces 31c having different reflecting angles from the reflecting position where the reflecting mirror surface 31a of the reflecting mirror 31 reflects light from a light source (not shown) and the reflecting angle are arranged vertically and horizontally. As a result, it has the advantage that shadows are less likely to occur not only in one direction but also in optical obstacles that extend in both the vertical and horizontal directions, compared to conventional ones. ing.

In other respects, the surgical light 30 is similar to the medical surgical light 20 shown in FIGS. 7A and 7B, and is not visible because it is covered by a light source (light shield plate 36). ) And the reflecting mirror 31 are integrated into a surgical lamp 30 fixed to a support frame 33 composed of a frame base 33a and a handle 33b, and this support frame 33 is rotatably mounted on a surgical lamp pole 34a. It is rotatably attached to the free arm 34. Reference numeral 32a denotes a lighting switch of the surgical light 30, and reference numeral 39 denotes a condensing irradiation area of the surgical light 30, which has a rectangular shape.

However, in the medical surgical light 30, the support frame 30 is supported by the free arm 34 so as to be rotatable in a substantially horizontal plane, and the medical surgical light 30 is swung up, down, left, and right. Although it could be rotated, it was not possible to rotate around the irradiation optical axis. Therefore, even if the handle 33b is operated, the direction of the condensed light irradiation area 39 cannot be rotated, and the characteristic that it is difficult to cast a shadow on an optical obstacle in both the vertical and horizontal directions is fully utilized. I didn't.

[0010]

[Problems to be solved by the invention]

 On the other hand, in medical treatment sites where medical surgical lights are used, there are occasions where it is desired to illuminate the illuminated part horizontally instead of vertically. For example, in dental applications, it is often desirable to follow the direction of the elliptical axis of the focused irradiation area in the left and right direction of the patient's face according to the shape of the patient's mouth.In obstetrics and gynecology and urology, According to the shape of the genital area, it is often desired to align the direction of the ellipse of the focused irradiation area vertically with respect to the front of the patient.

[0011] In such a case, the above-mentioned conventional medical operating lights cannot cope with such a situation, the operation is not simple, it is inconvenient when changing frequently, and the reflections in the vertical and horizontal directions are difficult. It was supposed that a mirror having a small mirror surface could not make full use of the characteristic that shadows could not be formed on an optical obstacle in either the vertical or horizontal direction.

[0012] Furthermore, a medical surgical lamp having a vertical condensing irradiation area cannot be diverted for the horizontal direction, and it is necessary to individually install a surgical lamp for each application. Operators who use shadow lights will increase equipment costs, and producers of shadow lights will have multiple specifications, increase inventory, troublesome product management, and contravene effective use of resources. Was supposed to be.

The present invention has been made in view of such circumstances, and can easily change the direction of a light-condensing irradiation area according to an illumination part and, if necessary, to obtain an ellipse for a frequent light-condensing irradiation area. It can also be used to change the direction of the axis, a single medical surgical light can be used for multiple medical applications, and it cannot cast shadows on optical obstacles in both vertical and horizontal directions. It is an object of the present invention to provide a medical surgical light capable of fully utilizing the characteristics of a medical surgical light.

[0014]

[Means for Solving the Problems]

 The medical surgical light according to claim 1 includes a reflector having an operating lamp reflecting mirror surface formed on an inner concave surface of an outer shell, a light source disposed on a central axis of an optical path of the reflecting mirror, and a reflecting mirror. A support frame provided with a rotation mechanism that supports the optical axis so as to be rotatable about a central axis of the optical path, wherein the rotation position of the reflecting mirror with respect to the support frame is changed. By doing so, the direction of the focused irradiation area is changed.

[0015] A medical surgical lamp here refers to one that reflects light from one light source to obtain a shadowless effect, and reflects light from one light source to form a fixed light source. The reflecting mirror used to converge light into the light irradiation area does not consist of a smooth continuous curved surface composed of parabolic curves, etc., so that light reflected from different positions and angles converges. And a plurality of small reflecting mirror surfaces having different reflecting positions and reflecting angles, respectively. In this way, even if the path of light reflected from one small reflecting mirror is obstructed by an obstacle, the path of light reflected from the other small reflecting mirror is less likely to be blocked because the light path is different. Can be obtained.

In this surgical light for medical use, light from a light source is reflected to generate reflected light that forms a condensed irradiation area in an elliptical or rectangular shape at a predetermined irradiation position by a rotating mechanism. The reflector having the reflector reflector surface is rotatably supported by the support frame, and only the reflector is rotated with respect to the support frame while maintaining the position and angle of the operating light. Thus, it is possible to change the direction of the focused irradiation area. For example, when the focused irradiation area has an elliptical shape, the direction of the elliptical axis can be rotated.

Therefore, a single surgical light can be used for various purposes, that is, for dental use, obstetrics and gynecology, and urology. In addition, since only the reflecting mirror composed of an aluminum molded product or a glass molded product is rotated, the force required for the rotation is smaller than that of moving the entire surgical light including the support frame. A small one is sufficient and can be easily rotated, and can cope with frequent rotation.

According to a second aspect of the present invention, there is provided a medical surgical light according to the first aspect, wherein the surgical light reflecting mirror surface includes a large number of vertically reflecting small mirror pieces each having a substantially parabolic cross section. It is characterized by being formed. In this operating lamp, the operating lamp reflecting mirror surface is formed by continuously arranging small reflecting mirror surfaces divided in only one direction in the vertical or horizontal direction. It occurs in only one direction, i.e., direction or lateral direction. In other words, this shadowless lamp has a feature that one of the obstacles that are long in the vertical or horizontal direction has a shadowless effect, but the other has little shadowless effect. . However, even in the case of such a reflecting mirror surface, this operating light allows the reflecting mirror to be easily rotated. It can be easily handled when it is important, and is convenient.

According to a third aspect of the present invention, there is provided a medical surgical light according to the first aspect, wherein the surgical light reflecting mirror surface is formed by arranging a large number of independent reflecting small mirror surfaces continuously in vertical and horizontal directions. It is characterized. In this operating light, the operating light reflecting mirror surface is formed by continuously arranging small reflecting mirror surfaces divided into two directions in the vertical and horizontal directions, and the shadowless effect also occurs in both the vertical and horizontal directions. is there. In other words, this surgical light has a shadowless effect even on obstacles that are long in the vertical or horizontal direction. In the case of using a reflector having such a reflector surface, this operating lamp can easily rotate the reflector, so that the direction of the condensed irradiation area can be adjusted without worrying about the direction of the shadowless effect. Since it is possible to irradiate the irradiating part taking only the direction into account, it is possible to make full use of the characteristics of the surgical light reflecting mirror surface, in which a shadow cannot be formed on an optical obstacle in both the vertical and horizontal directions.

According to a fourth aspect of the present invention, there is provided a medical surgical light according to any one of the first to third aspects, wherein the rotating mechanism manually rotates an operation unit provided on the reflecting mirror, thereby causing the reflecting mirror to rotate. The mirror is configured to set a rotation position with respect to the support frame. This operating lamp is convenient because the reflecting mirror can be manually rotated.

According to a fifth aspect of the present invention, there is provided a medical surgical light according to any one of the first to third aspects, wherein the rotating mechanism has a rotary driving unit for rotating a reflecting mirror, and the rotary driving unit includes the rotary driving unit. It is characterized in that it is operated to set the turning position of the reflecting mirror with respect to the support frame. In this operating light, the reflecting mirror can be rotated by the rotation driving means, and can be rotated without touching the reflecting mirror. It is possible to prevent the operator's hands from being contaminated by operating lights, which is advantageous in terms of safety and health.

Is formed.

The shape of the condensed irradiation area is appropriately determined according to the use of the surgical light, but usually, an oval shape, a rectangular shape, or a rectangular shape, which will be described later with reference to FIGS. In many cases, the shape is elliptical. Hereinafter, a case where the shape is an elliptical shape will be described. The light source 2 is configured by a lamp such as a quartz halogen lamp and an incandescent lamp.

The support frame 3 is a structure that supports the entire surgical light 10. The support base 3 a is supported by a support means (not shown), and a front surface of the surgical light 10 is provided with respect to the frame base 3 a. The handle 3b is supported so as to be able to swing up and down as viewed from above. The handle 3b plays a role of mounting the light source 2, the holder 4, and the like, and a role of moving or rotating the entire surgical light 10.

The holder 4 accommodates and supports the light source 2 so as to be able to conduct electricity. The light source accommodating portion 5 is fixed to the handle 3b, and accommodates and supports the holder 4. The light-shielding cover 6a is fixedly supported by the handle 3b, and covers the light-emitting portion of the light source 2, and blocks direct light from the light source 2 forward. The transparent cover 6b covers the front surface of the reflecting mirror 1 and protects the reflecting mirror 1. The reflector turning knob 7 is provided on the peripheral edge of the reflecting mirror 1 to turn the reflecting mirror 1.

The reflector holding member 8 is adapted to be engaged and locked with an opening of the light source housing 5 by a suitable engaging means such as a screw fitting. The reflector 1 is rotatably attached to the light source housing 5 by sandwiching the central portion of the reflector 1 between the light source housing 5 and the light source housing 5. The opening of the housing 5, the reflector holding member 8, and the reflector turning knob 7 form a turning mechanism.

In the medical surgical light 10 having the above-described configuration, by operating the reflector turning knob 7 lightly by hand, the support frame 3, that is, the light source 2 can be easily and simply adjusted. As a result, the reflecting mirror 1 can be rotated, and the direction of the condensed irradiation area formed by the reflecting mirror 1 can be changed. Further, in the reflecting mirror 1 of the surgical light, the shadowless effect is also generated only in one direction of the vertical direction or the horizontal direction. In other words, this operating lamp has the characteristic that one of the obstacles that are long in the vertical or horizontal direction has a shadowless effect, but the other has little shadowless effect. . However, even in the case of such a reflecting mirror 1, this operating lamp allows the reflecting mirror 1 to be easily rotated. It is easy to respond to when you want to emphasize the effect, and it is convenient.

FIG. 3 is a front view showing an example in which the reflecting mirror is rotated in the medical surgical light of the present invention. This medical surgical light 10 is the same as that shown in FIG. 1 (b), and the same portions are denoted by the same reference numerals and redundant description will be omitted. 1 (b), the reflector 1 is rotated clockwise 90 degrees by manually operating the reflector rotating knob 7. As shown in FIG. It was moved. As can be seen from this figure, by rotating the reflecting mirror 90 degrees, the longitudinal direction of the vertically reflecting small mirror piece 1b constituting the operating lamp reflecting mirror surface 1a changes by 90 degrees. It can be seen that the direction of the condensed irradiation area formed by the reflected light is also rotated by 90 degrees.

FIGS. 4A and 4B are external perspective views illustrating a state of forming a condensing irradiation area of the medical surgical light of the present invention. Also in this figure, the same parts as those described so far are denoted by the same reference numerals, and redundant description will be omitted. Here, the frame base 3a of the medical surgical light 10 is supported by a free arm 12 which is an example of support means for the surgical light.

In FIG. 4A, when viewed from the front, the reflector turning knob 7 is located on the left side, and at this time, the vertically long direction of the vertically long reflecting small mirror piece 1 b is up and down. Reference numeral 9 denotes a condensed irradiation area formed by the medical surgical lamp 10. As can be seen from this figure, the lengthwise direction of the vertically reflecting small mirror piece 1b and the length of the oval condensed irradiation area 9 are shown. It is orthogonal to the circular axis direction. On the other hand, FIG. 4B shows a state where the reflecting mirror 1 is rotated by operating the reflecting mirror turning knob 7 so that the knob 7 is directly above.

As can be seen from this figure, when the reflecting mirror 1 is rotated by 90 degrees, the direction of the condensed irradiation area 9 to be formed, that is, the direction of the long axis of the condensed irradiation area 9 having an oval shape Also rotates 90 degrees. Further, according to the present invention, only the reflecting mirror 1 can be rotated without changing the position and irradiation direction of the surgical light 10 itself, and only the direction of the condensing irradiation area 9 can be rotated. it can.

For example, since the condensed irradiation area 9 having a horizontally long oval shape as shown in FIG. 4A is suitable for the shape of the oral cavity of a patient, it can be suitably used for dental treatment. ) Is suitable for the shape of the pubic region of a patient, and can be suitably used in obstetrics and gynecology and urology. FIG. 5 is a front view showing another example of the medical surgical light of the present invention.

The medical surgical light 10 A is different from the medical surgical light 10 described above only in the configuration of the surgical light reflecting mirror surface of the reflector. The operating light reflecting mirror surface 1c of the reflecting mirror 1A of the medical operating light 10A has a smaller vertically long reflecting small mirror piece 1b than the operating light reflecting mirror surface 1a of the reflecting mirror 1 of the operating light 10 in FIG. The difference is that a large number of independent reflecting small mirror surfaces 1d are formed continuously and vertically and horizontally instead of being formed so as to be continuously arranged in parallel in the direction.

When such a reflecting mirror 1A having the reflecting mirror surface 1c is used, the shadowless effect of the operating lamp also occurs in both the vertical and horizontal directions. In other words, this surgical light has a shadowless effect even on obstacles that are long in either the vertical or horizontal direction. In the case of using a reflector having such a reflector surface 1c, this operating lamp allows the reflector to be easily rotated. Since the illuminated area can be illuminated by considering only the direction of the mirror, it is possible to make full use of the characteristics of the operating lamp reflecting mirror surface, which does not cast a shadow on an optical obstacle in either the vertical or horizontal direction.

FIG. 6 is a partial cross-sectional view showing a main part of the rotation driving means of the reflecting mirror of the present invention. This medical surgical light is characterized in that a rotary driving means for automatically rotating a reflecting mirror, not manually, is provided. Also in this figure, the same parts as those described so far are denoted by the same reference numerals, and redundant description will be omitted. The handle 3b of the medical surgical light 10B is provided with a rotation driving means mounting recess 3c at an appropriate position, and the rotation driving means 11 is installed in this recess 3c.

The rotation driving means 11 includes a motor 11 a for rotationally driving the reflecting mirror 1, a fixed support for the motor 11 a, a support for the entire rotation driving means 11, and a base 11 b fixed and installed in the recess 3 c. A drive roller 11c attached to the output shaft of the motor 11a and having an outer periphery made of urethane rubber or the like, a driven roller shaft 11d erected on a base 11b at an appropriate distance from the output shaft of the motor 11a, The driven roller 11e is rotatably attached to the moving roller shaft 11d, and has a driven roller 11e whose outer periphery is formed of urethane rubber or the like.

The driving roll 11c and the driven roll 11e are provided at positions facing each other with a predetermined gap therebetween, and a peripheral portion of the reflecting mirror 1 is pressed between the two rolls 11c and 11e by an appropriate pressure. In place of the knob for turning the reflecting mirror of the manual turning mechanism shown in FIGS. 1 to 5, a turning mechanism having a rotation driving means 11 is formed.

Therefore, in this state, when the driving roll 11c is rotated by the motor 11a, the peripheral edge of the reflecting mirror 1 is rotated, and the reflecting mirror 1 is rotated. The driven roll 11e is rotated by the drive roll 11c and rotates along with the drive roll 11c, so that the driven mirror 11e is applied to the periphery of the reflector 1 while rotating. The pressure state is maintained, and the rotation of the reflecting mirror 1 by the driving roll 11c is smoothly performed.

According to the medical surgical light 10 B, the reflecting mirror 1 can be rotated without touching the reflecting mirror 1 by controlling the motor 11 a by an appropriate switch such as a foot pedal. It is possible to prevent contamination of the surgical light by the surgeon's hand and contamination of the operator's hand by the surgical light, which is advantageous in terms of safety and health. In the above embodiment, the shape of the outer shell of the reflecting mirror was a circular one, but if the desired shape of the focused irradiation area could be obtained, the outer shell would be almost rectangular. Or an oval shape can be adopted as appropriate.

[0041]

[Effect of the invention]

 According to the medical surgical light according to the first aspect, while maintaining the position and angle of the surgical light, only the reflecting mirror is rotated with respect to the support frame to change the direction of the condensing irradiation area. Because it can be modified, a single operating light can be used for multiple purposes: dental, obstetrics and gynecology, and urology.

Further, since only the reflecting mirror made of an aluminum molded product or a glass molded product is rotated, the force required for the rotation is required to move the entire surgical light including the support frame. In comparison, a small one is sufficient, can be easily rotated, and can cope with frequent rotation. According to the medical surgical light according to the second aspect, in addition to the effect of the medical surgical light according to the first aspect, the surgical light reflecting mirror surface has a shadowless effect in the vertical or horizontal direction. Even if it occurs in only one direction, the reflecting mirror can be easily rotated, making it easy to focus on the direction of the focused irradiation area and to emphasize the shadowless effect. It is convenient and convenient.

According to the medical surgical light according to the third aspect, in addition to the effect of the medical surgical light according to the first aspect, the surgical light reflecting mirror surface has the shadowless effect in both the vertical and horizontal directions. In this case, the reflecting mirror can be easily rotated, and it is possible to irradiate the irradiated area only by considering the direction of the focused irradiation area without worrying about the direction of the shadowless effect. Because of this, it is possible to make full use of the characteristics of the surgical light reflecting mirror surface, which does not allow shadowing of optical obstacles in both vertical and horizontal directions.

According to the medical surgical light according to the fourth aspect, in addition to the effect of the medical surgical light according to any one of the first to third aspects, the reflecting mirror can be manually rotated. It is convenient. According to the medical surgical light according to the fifth aspect, in addition to the effect of the medical surgical light according to any one of the first to third aspects, the medical operating light can be rotated without touching the reflecting mirror.
