Description

The present invention relates to a head-mounted medical lighting device that is attached to the head of a medical practitioner during a surgical operation, etc., and irradiates light onto the treatment area of the patient. The present invention relates to a medical head mount that fits well and prevents the direction of light irradiation from shifting from the target treatment area.

BACKGROUND ART In surgical operations in hospitals and the like, a practitioner approaches a patient lying on a bed or chair and performs the surgical operation. The practitioner usually performs the treatment in a standing position, moves around the room, frequently changes surgical instruments such as scalpels, scissors, forceps, etc. during the treatment, and gives instructions to nurses and others assisting with the treatment. The need to give and change the direction of the head also arises.

In such cases, the medical lighting device that the practitioner wears over his or her head to irradiate the patient's treatment area with light may fluctuate and become misaligned, or the device may be placed above the bed or chair or on the side of the head. The head mount may move due to contact with various installed instruments, treatment assistants, or nurses.

In addition, as a preparation before starting the treatment, it is necessary to quickly and smoothly attach the medical lighting device. Furthermore, after wearing the medical lighting device, the practitioner is required to perform operations to finely adjust the mounting position of the medical lighting device and correct the irradiation direction of the light source. Furthermore, if the practitioner feels that the illuminance at the surgical site at hand is insufficient during the treatment, it becomes necessary to increase the illuminance of the medical lighting device.

For this reason, medical lighting devices have traditionally been easy to install, and furthermore, the light from the light source can be emitted in the same direction as the practitioner's line of sight, ensuring sufficient illuminance at the treatment area of the patient. Various types of medical lighting devices have been devised (for example, see Patent Document 1, Patent Document 2, and Patent Document 3).

In the medical lighting device of Patent Document 1, in order to make the front light irradiation part light and compact, the light irradiation part and the LED light source are connected with an optical fiber cable, etc., and the light guide part including the optical fiber cable is long. This invention discloses a medical lighting device that solves the problem that the illuminance of light from the light irradiation section decreases.

Further, the medical illumination device of Patent Document 2 transmits a control signal when the user's field of view is directed toward an object desired by the practitioner, so that the practitioner can use the medical head during treatment. This invention discloses a lighting device that reduces the need for minute adjustments and changes in the light irradiation direction of a mount.

In addition, the medical head mount of Patent Document 3 includes a group of LEDs arranged in an array on a circuit board in the headrest, a power supply that supplies power to the LEDs, and a control unit to accurately illuminate the area where surgery is performed. A control unit including a switch, and a head mount incorporating a control unit are disclosed.

Further, in Patent Document 4, similarly to Patent Document 1, a light source unit consisting of an LED and a light irradiation section such as a lens are separated, and the light source unit and the light irradiation section are connected by an optical fiber cable. This headrest discloses a headrest in which the volume of the light irradiation part is reduced by incorporating a heat sink and a heat insulating member together with an LED, and the light source unit is attached near the eyes of the practitioner.

Patent No. 6234749 Japanese Patent Application Publication No. 2006-107846 Japanese Patent Application Publication No. 2006-175235 International publication WO02/099332A1

Surgery and other procedures must be started quickly after the practitioner enters the operating room due to anesthesia, blood transfusion, etc., and the head mount must be attached quickly and smoothly. be. Further, after wearing the head mount, the practitioner makes slight adjustments to the mounting position of the head mount and the irradiation direction of the light source. In addition, the practitioner should adjust the irradiation brightness of the headrest when a delicate and precise operation is required during the procedure, such as suturing blood vessels, or if the practitioner feels that the illuminance at the surgical site at hand is insufficient during the procedure. In some cases, it may be necessary to perform an adjustment operation to increase the amount.

In addition, if the treatment is for a long time (more than 5 hours), or if the practitioner is in a stooping position while facing the patient's treatment area at a constant angle, a headrest may be required. It is desirable for the headrest to be as small, lightweight, and generate low heat as possible.In order to maintain a forward-slouched posture for a long time, the torque (length x weight) acting in the direction of gravity on the head with the headrest attached should be minimized as much as possible. There is a need.

For this reason, in recent years, LED elements are used in the light irradiation part as disclosed in Patent Documents 1 to 4, but LED elements are powered by a DC power source (DC current), have low heat generation, are highly efficient, Emits light. For this reason, from the viewpoint of ease of movement for the practitioner, a type in which a battery is mounted inside the headrest as a power source for the LED elements is often used, as disclosed in Patent Document 3, for example.

However, conventional head mounts, including the above-mentioned head mount, have had the following problems to be solved. That is,
(a) The conventional head mounts described above are not necessarily satisfactory in terms of ease of mounting the head mount and ease of operation during treatment. In other words, since the practitioner's fingers and fingers are covered with the patient's blood and body fluids during the treatment, the operation of the headrest must be simpler and easier.

(b) The practitioner mainly performs the treatment in a standing position, moves around the room, frequently changes surgical instruments such as scalpels, scissors, forceps, etc. during the treatment, and nurses and others assisting with the treatment work. Since it is necessary to give instructions and change the direction of the head, the attachment status of the head mount worn over the head may fluctuate and become misaligned, and various objects placed above the bed or chair or on the side of the head may The head mount could move or come off the head due to contact with instruments, treatment assistants, or nurses.

(c) Although LED elements are highly efficient, the batteries that drive them are heavy, so in order to reduce the weight of the head mount, it is necessary to separate the light source unit and the light irradiation part using optical fiber cables. It is necessary to connect with etc. In such cases, in order to be able to use a small battery for a longer period of time, it is necessary to minimize the amount of light leaking from the light emitting part, even if the light guide part including the optical fiber cable becomes long. It is necessary to prevent the illuminance of the light from decreasing.

In view of the above-mentioned problems, the present invention has excellent wearability, excellent operability, no risk of the head mount moving or coming off the head, and a device that can be used for long periods of time without fatigue. The purpose is to provide a medical head mount that can be used for medical purposes.

For this reason, the present invention allows a practitioner to attach or detach one or more of an LED light source device, an imaging device, a binocular loupe, or a VR display, and a control unit by attaching the device to the head during a surgical operation or the like. It is a medical head mount that is installed in a medical head mount that extends seamlessly from the forehead of the practitioner's head, left and right temporal regions, to the back of the head, and is shaped so that it does not shift when pressed around the practitioner's head. A vertical belt connects the circumferential belt in a semicircular arc shape from the front of the head to the top of the head and the back of the head of the practitioner. a first adjusting means for adjusting, a second adjusting means provided on the vertical belt and adjusting the length of the vertical belt, and a second adjusting means provided on the circumferential belt or the vertical belt at a position on the forehead side of the practitioner. , an LED light source mounting part for removably mounting the LED light source device; and a removably mounting an imaging device that is provided near the LED light source mounting part and captures an image in a direction irradiated by the LED light source. a binocular loupe mounting part provided below the LED light source mounting part for removably mounting a binocular loupe for visually magnifying the treatment area; A removable control unit is attached between the connecting portion of the belt and the circulating belt, and is capable of mounting a control unit for turning on/off the LED light source device and/or the imaging device, adjusting the amount of light, or adjusting the recorded image. A control unit mounting part for mounting on the control unit.

Here, the first adjustment means is provided at a rear connection point of the circumferential belt with the vertical belt, and is constituted by a rotation lock mechanism having a rotation knob for adjusting the length of the circumferential belt.

The second adjusting means is attached to a portion of the vertical belt extending from the top of the head to the forehead, and is configured by a slide lock mechanism having a slide knob for adjusting the length of the vertical belt. Alternatively, a rotation lock mechanism having a rotation knob for adjusting the length of the vertical belt may be used.

The medical head mount according to the present invention has the following effects due to the above configuration. That is,
(a) Since the LED light source device attached to the front of the headband can freely adjust the direction of illumination from the forehead of the practitioner in both the vertical and horizontal directions, The belt that goes around from the front of the head to the back of the head makes it possible to irradiate light in the desired direction just by lightly touching a finger or part of the hand (sliding or rotating the knob). Since the illumination device circulates seamlessly from the forehead of the patient's head to the temporal region and the back of the head, the illumination device will never come off the head of the practitioner under any circumstances.

(b) Furthermore, the circumferential belt is designed to maintain pressure on both sides of the practitioner's head and prevent it from shifting, so even if the practitioner suddenly moves his or her head, Even if the first adjusting means for adjusting the length of the circumferential belt is used for a long time without being tightened too strongly, the head (head circumference) will not experience pain due to being tightened. This is an important factor in this medical head mount, as it can be easily understood from the fact that even if the ear straps on the left and right sides of a mask are loose, the ears will hurt if used for a long time.

(c) The first adjusting means for adjusting the length of the circumferential belt can be easily adjusted by, for example, a clockwise or counterclockwise rotation operation, and the first adjusting means Since it is located at the rear connection point between the circumferential belt and the vertical belt, once it is adjusted, it will not obstruct your vision.Furthermore, since it is not located on the side of your head, it will not interfere with your vision. No contact with equipment, nurses, or treatment assistants.

(d) The second adjusting means for adjusting the length of the vertical belt is disposed at the rear part of the longitudinal belt from the front of the practitioner's head, and is operated by a slide knob or a rotary knob in the same manner as the first adjusting means described above. , the practitioner can easily adjust the length with one hand (fingertips), and it does not obstruct vision.Furthermore, since it is not located in front of the crown of the head, it is easy to adjust the length around the bed where the treatment is performed. No contact with equipment, nurses, or treatment assistants.

In addition, as a first aspect of the present medical head mount, an LED light source device is attached between the central part of the vertical belt and the connection part with the circumferential belt at the back of the head to enable adjustment of the amount of light from the LED light source device and on/off operation. An LED light source control unit section is provided. This allows the practitioner to adjust the amount of light irradiated from the LED light source device by himself or herself during the treatment.

Here, the control unit is attached to the vertical belt so that it is in the highest position when viewed from the side when the practitioner is bent forward at a predetermined angle toward the treatment area of the patient during the treatment. Placed.

As a result, in this medical head mount,
(e) When a practitioner performs a treatment while maintaining a forward-leaning posture for a long period of time, it is desirable that the headrest be as small, lightweight, and generates low heat as possible. This minimizes the torque (length x weight) that acts in the direction of gravity on the head when the headrest is attached, thereby minimizing the burden on the lower back and neck of the practitioner.

The present medical head mount is characterized in that the control unit incorporates an electric circuit for supplying power that can adjust the amount of light from the LED light source device, and a small-capacity battery as necessary. shall be.

This results in
(f) For relatively short treatments, the high-efficiency, low-power-consuming LED light-emitting elements allow the practitioner to carry out the treatment without being tied down by a cord for receiving power from an external source. be able to.

Further, in the present medical head mount, the LED light source device is equipped with an imaging device including a lens and an imaging element, and the imaging device is stored in a storage device disposed within the control unit, and the LED light source device is The image data may be activated by turning on the light source device, and image data may be transmitted to and stored in the storage device. In this imaging device, one arbitrarily selected from one or a plurality of imaging devices prepared in advance is attached to the imaging device mounting section or the light source device, and the imaging direction thereof can be adjusted.

The second aspect of the present medical head mount consists of the headband having the above-described structure and a waist belt attached to the waist of the practitioner. Behind the waist belt, there is a large-capacity battery and the head It features a belt power pack equipped with a jack for plugging in a cord for electrical connection to the control unit mounted on the band.

This results in
(g) Treatments can be performed for long periods of time without being restricted by cords.

Also in this second aspect, the LED light source device is equipped with an imaging device including a lens and an imaging element, and the imaging device is stored in a storage device disposed within the belt power pack, and the LED light source device is It is activated by turning on the device, and image data can be sent to and stored in the storage device.

This medical head mount can be used to attach binocular loupes, but a VR display can be attached in place of the binocular loupes. As a result, for example, when medical students and residents are undergoing surgical training, they can see through the video images of the actual surgery being performed at the surgical site (along with the actual surgical images), and view the educational information on the VR display. The surgeon can show the nurses and assistants attending the surgical procedure various instructions, such as showing videos and explanations, and showing them what scissors, forceps, etc. should be prepared for the next surgery, depending on the progress of the surgery, without the surgeon having to give instructions one by one to the nurses and assistants attending the surgery. It can be used for a variety of purposes, such as displaying images that prompt the preparation of instruments, or displaying images of past successful surgeries for reference by the operating surgeon.

As described above, the medical head mount according to the present invention has excellent wearability and operability, and there is no risk that the head mount will move or come off the head, even when used for a long time. This made it possible to use it without getting tired.

Hereinafter, optimal embodiments of the present invention will be described with reference to the drawings.

FIG. 1A shows the configuration of a medical head mount 1 according to a first embodiment of the present invention. FIG. 1B shows the configuration of a medical head mount 1 according to a second embodiment of the present invention. The medical head mount 1 according to the first embodiment shown in FIG. 1A and the medical head mount 1 according to the second embodiment shown in FIG. 1B have a second adjustment means for adjusting the length of the vertical belt 22. However, the example shown in FIG. 1A is a slide knob type length adjustment means 12A (FIG. 1A), and the example shown in FIG. 1B is a rotary knob type length adjustment means 12B.

When the medical head mount 1 according to the present invention shown in FIGS. 1A and 1B is attached to the head of a practitioner as shown in FIG. A circumferential belt 21 is formed so as to rotate without any movement and keep both sides of the head of the practitioner in a pressed state so as not to shift, and a vertical belt 22 connects the forehead to the back of the head of the practitioner in a semicircular arc shape. A first adjusting means 11 is provided at the rear connection point of the circumferential belt 21 and the vertical belt 22 and is used to adjust the length of the circumferential belt 21 by clockwise or counterclockwise rotation, and a first adjusting means 11 is provided in the front of the vertical belt 22. In the embodiment shown in FIG. 1A, the length of the vertical belt 22 is adjusted by sliding the slide knob 12A, and in the embodiment shown in FIG. 1B, the length of the vertical belt 22 is adjusted by rotating the rotary knob clockwise or counterclockwise. It has a second adjustment means 12A or 12B that is adjusted by operation.

As shown in FIG. 3, a gear shaft 64 is inserted into the back surface of each of the rotary knob type first adjusting means 11 shown in FIGS. 1A and 1B and the rotary knob type second adjusting means 12 shown in FIG. 1B. A through hole 60 is formed. The gear shaft 64 includes pinion gears 65 that extend radially from the shaft 64a at equal intervals.

The circumferential belt 21 is usually composed of one belt, and elongated holes 62 and 63 are provided at both ends thereof, and a rack gear 62a that meshes with a pinion gear 65 is provided in the lower straight portion of the elongated hole 62. A rack gear 63a that meshes with the pinion gear 65 is formed in the upper straight portion of the elongated hole 43. Therefore, by overlapping the elongated holes 62 and 63 at both ends of the orbiting belt 21 and meshing the rack gears 62a and 63a with the pinion gear 65, the orbiting belt 21 is held in an annular shape, and the first adjusting means 11 is rotated clockwise or When the pinion gear 65 is rotated counterclockwise, the pinion gear 65 reciprocates within the long holes 62 and 63, thereby making it possible to adjust the medical head mount 1 according to the size of the wearer's head.

Although the vertical belt 22 is also composed of two belts, it differs from the circumferential belt 21 in that it becomes one belt by being connected to each other. However, like the circumferential belt 21, the vertical belt 22 also has elongated holes 62 and 63 having rack gears 62a and 63a formed at the end of each connection side. By meshing both with the pinion gear 65, they are connected as one. As shown in FIG. 1A, an example is shown in which adjustment is performed by sliding the slide knob button of the second adjustment means (slide knob type) 12A while pressed, and as shown in FIG. 1B, the second adjustment means (slide knob type) When the rotation knob 12B is rotated clockwise or counterclockwise, the pinion gear 65 reciprocates within the elongated holes 62 and 63, thereby changing the size of the medical head mount 1 from the forehead to the back of the head of the wearer. Adjustments can be made accordingly.

An LED light source mounting part 23 for removably mounting the LED light source device 14 is provided on the circumferential belt 21 or the vertical belt 22 at a position on the forehead of the practitioner. In the illustration, the LED light source mounting portion 23 is provided at a portion where the circumferential belt 21 and the vertical belt 22 overlap at the frontal region of the forehead of the practitioner. As the LED light source mounting part 23, for example, a hook-and-loop fastener can be used, and one of the hook surface of the hook-like raised surface of the hook-and-loop fastener or the loop surface of the hook-like raised surface of the hook-and-loop fastener is attached to the circumferential belt 21 or the vertical belt 22. is glued to the front of the practitioner's head.

The aperture of the aperture mechanism 37 is adjusted by turning a pin 37a that projects outward.

A link mechanism 9 having a set of link plates is provided at the rear of the main body portion 16. The other end of the link mechanism 9 is provided with a detachable part 10 that can be attached to and detached from the LED light source mounting part 23. A loop surface (or hook surface) that sticks to the hook surface (or loop surface) of the hook-and-loop fastener of the LED light source mounting section 23 is adhered to the back surface of the detachable section 10 . Therefore, the LED light source device 14 can be detachably attached to the medical head mount 1 using a hook-and-loop fastener. The main body part 16 of the LED light source device 14 can be expanded and contracted back and forth and moved up and down by adjusting the link mechanism 9, and is attached so as to be movable left and right with respect to the link plate to which it is connected.

The circumferential belt 21 is provided with an auxiliary piece 21a extending downward from a portion that overlaps with the vertical belt 22 at the frontal region of the forehead of the practitioner. The auxiliary piece 21a includes an imaging device mounting part 24 for removably mounting an imaging device 30 for capturing an image in the direction in which the LED light source device 14 irradiates the light source, and for visually enlarging the treatment area. A binocular loupe attachment part 25 is provided for detachably attaching a binocular loupe. The imaging device mounting section 24 and the binocular loupe mounting section 25 are configured with pockets into which attachment pieces for an imaging device 40 and a binocular loupe 50, which will be described later, can be inserted.

The imaging device 40 captures moving images or still images using a CCD or CMOS image sensor, and as shown in FIG. 6, power and control signals are supplied from a flat flexible cord 41, and the image sensor outputs an imaging signal. By using an ultra-small micro camera 42 in the imaging device 40, it can be easily worn and held by a doctor when performing surgery. For example, such a micro camera has external dimensions of 16.5 mm (W) x 10.3 mm (H) x 18.0 mm (D) and is equipped with a 13.19 million pixel image sensor, and is capable of producing full high-definition videos and high-definition videos. Micro cameras that can capture high-quality still images are commercially available, and such cameras are suitable as the imaging device 40 to be attached to the medical head mount 1 according to the present invention. The micro camera 42 is attached to a base 43 having an attachment piece 43a, and is attached to the medical head mount 1 by inserting the attachment piece 43a into the imaging device attachment part 24.

The imaging device 40 is attached near the LED light source mounting section 23 in order to capture an image in the direction in which the LED light source device 14 irradiates the LED light.

The primary mirror mounting frame 51 extends downward from the bridge and is provided with a mounting piece 51a, and is mounted on the medical head mount 1 by inserting the mounting piece 51a into the binocular loupe mounting portion 25.

Since the binocular loupe 50 can be attached to the medical head mount 1 using the binocular loupe attachment part 25, it may be of a type that does not have the frame ridge part 56. However, since the binocular loupe main body 52 is relatively heavy, the burden on the wearer is reduced by supporting it at three points: the two frame tendrils 56 and the medical head mount 1 via the binocular loupe attachment part 25. be done.

In this way, the imaging device mounting part 24 and the binocular loupe mounting part 25 have been described as pockets into which the respective mounting pieces 43a and 51a are inserted, but they may also be made of hook-and-loop fasteners like the LED light source mounting part 23, or the LED light source mounting part The reference numeral 23 may be a pocket into which the detachable part 10 of the LED light source device 14 is inserted. As another aspect, a protrusion or pin is provided on the LED light source 14, imaging device 30, and binocular loupe 50 side, and the LED light source mounting part 23, imaging device mounting part 24, and binocular loupe mounting part 25 have this protrusion or pin. It can also be configured with a receiving part that fits in and is held detachably, and various other configurations are possible.

A VR display 60 shown in FIG. 8 can also be attached to the binocular loupe attachment section 25. Here, in the present application, the VR display 60 includes a flat display or a curved display, for example, a goggle-shaped display. Furthermore, the image displayed on the VR display 60 is a two-dimensional image or a three-dimensional image.

Furthermore, the VR display used in the present invention is a display equipped with a lens 61 that allows users to experience virtual reality. In addition, an educational video is displayed on the VR display through the video image of the surgery actually being performed at the surgical site (along with the actual surgical image), for example, the video of the surgical site captured by the imaging device 40, etc. In addition, the explanation is semitransparently displayed, and displays or images to assist the treatment are displayed.

In addition, the image prompts nurses and assistants attending a surgical operation to prepare the next surgical instruments such as scissors and forceps according to the progress of the operation, without the operating surgeon having to instruct them one by one. It can be used for a wide range of purposes, such as displaying images of past successful surgeries, etc., for reference by the operating surgeon.

FIG. 8 shows the back side of the VR display 60 (the side facing the user's face when worn), and there is a mounting plate on the top of the shielding part 62 for shielding the user's eyes from the outside world when worn. 62a is provided, and by inserting the attachment piece 62a into the binocular loupe attachment part 25, it is attached to the medical head mount 1. The VR display of this example is heavy because it is a stand-alone type with a built-in battery and CPU, but if it is attached to the medical head mount 1 according to the present invention, it can be stably worn on the user's head. can.

A control unit 13 for turning on/off the LED light source device 14 and/or the imaging device, adjusting the amount of light, or adjusting the recorded image is detachably connected between the central part of the vertical belt 22 and the connection part with the circumferential belt 21 at the back of the head. can be attached to. A control unit attachment part 26 is provided between the center of the vertical belt 22 and the connection part with the circumferential belt 21 at the back of the head.

As shown in FIG. 9(a), the control unit mounting portion 26 is constituted by a cylindrical pin, and the diameter of the upper end portion of this pin is in the shape of a dish larger than the diameter of the cylindrical portion. A groove 27 is formed on the back surface of the control unit 13 along the longitudinal direction of the vertical belt 22. As shown in FIG. 9(b), the widthwise dimension of the groove 27 is approximately equal to the diameter of the cylindrical portion of the control unit mounting portion 26, and one end of the groove 27 is provided with a plate at the upper end of the control unit mounting portion 26. An insertion portion 27a into which a shaped portion can be inserted is formed. Therefore, one of the control units 13 arbitrarily selected from one or more control units prepared in advance can be mounted on the control unit mounting section 26. When the control unit 13 is attached to the control unit mounting section 26, the control unit 13 can be seen from the side when the practitioner is leaning forward at a predetermined angle toward the treatment area of the patient during the treatment. It is placed so that it is at the highest position.

The control unit 13 is connected to the LED light source device 14 and/or the imaging device 30 via a harness 13a, and supplies an on/off signal, a light amount adjustment signal, or a recording image adjustment signal, and also outputs the LED light source device 14 and the imaging device 30 from a built-in battery.
