Description

[Technical Field]

[0001] The present invention relates to a laser pointer that is worn on the head of a worker. [Background technology]

[0002] Conventionally, there have been laser pointers that are worn on the head of a surgeon during surgery to indicate a specific position to an assistant. For example, Patent Document 1 listed below discloses a laser pointer that can switch a laser emitting unit on and off (hereinafter also referred to as "on / off operation") by moving the laser pointer attached to the surgeon's head closer to or farther away from a proximity sensor attached to the surgeon's shoulder. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2015-148705

[0004] However, with the laser pointer described in Patent Document 1, the surgeon must move his or her head during surgery to turn the laser on and off, which makes it difficult for the surgeon to maintain his or her gaze on the area he or she is focusing on, which interferes with the surgery.Furthermore, with the laser pointer described in Patent Document 1, the battery is housed in the housing, so if the battery power runs low during surgery, the laser pointer must be removed from the surgeon's head and the battery must be replaced, which also interferes with the surgery.

[0005] The present invention has been made to address the above-mentioned problems, and its object is to provide a laser pointer that can reduce interference with the work performed by an operator such as a surgeon. Summary of the Invention

[0006] In order to achieve the above object, the present invention is characterized in that it is a laser pointer that is attached to the head of a worker, and includes a laser light source that emits laser light, a head-mounted device for attaching the laser light source to the head of the worker, a functional unit that has at least one of the functions of causing the laser light source to emit or stop emitting laser light and supplying power, and wiring for the functional unit that electrically connects the laser light source and the functional unit, and the wiring for the functional unit is formed to a length that allows the functional unit to be positioned behind the worker when the laser light source is attached to the head of the worker by the head-mounted device.

[0007] According to this, when the laser light source of the laser pointer is attached to the head of the worker using the head-mounted device, the wiring for the functional unit is formed to a length that allows the functional unit to be positioned behind the worker. With a laser pointer configured in this way, when the worker wants to start or stop emitting laser light from the laser light source, the worker can ask someone nearby to turn the laser pointer on and off behind the worker without interrupting their work. In other words, this laser pointer allows the on / off operation of the laser pointer to be performed behind the worker in parallel with the worker's work, thereby reducing interference with the worker's work.

[0008] Furthermore, in a laser pointer configured in this manner, if the power of the power source becomes low during work, the worker can ask someone nearby to replace the batteries behind the worker, without having to remove the laser light source from the worker's head. In other words, with this laser pointer, the power source can be replaced behind the worker while the worker is working, thereby reducing the disruption to the worker's work.

[0009] Another feature of the present invention is that the laser pointer further comprises a back attachment device for attaching at least one of the functional unit and the wiring for the functional unit to the back side of the operator.

[0010] According to this, the laser pointer is equipped with a back-attached device for attaching at least one of the functional unit and the functional unit wiring to the back side of the worker, so that the functional unit and / or the functional unit wiring can be attached to the back side opposite the chest side where the worker works, thereby reducing the interference of the functional unit and / or the functional unit wiring with the worker's work. Also, because this laser pointer supports the functional unit and / or the functional unit wiring on the back side of the worker by the back-attached device, it is possible to reduce the interference of the worker with their concentration caused by the functional unit and / or the functional unit wiring swinging in response to the worker's body movements.

[0011] Another feature of the present invention is that in the laser pointer, the back attachment can be attached to the neck portion of clothing worn by the worker.

[0012] According to this, the back-worn device for the laser pointer can be attached to the neck area of ​​the clothing worn by the worker. Therefore, the back-worn device can be used to attach the functional unit and / or the wiring for the functional unit to the collar, making it easy to attach the functional unit and / or the wiring for the functional unit to the worker's clothing and to maintain the attached state. Furthermore, when the functional unit is attached to the neck area of ​​the worker's clothing by the back-worn device, the functional unit of the laser pointer can be supported on the worker's shoulders, reducing discomfort or damage to the clothing when worn due to the weight of the functional unit pulling on the clothing.

[0013] In order to achieve the above object, the present invention is characterized in that it is a laser pointer that is attached to the head of a worker, and includes a laser light source that emits laser light, a head-mounted device for attaching the laser light source to the worker's head, and a foot switch that causes the laser light source to emit or stop laser light by operating the worker's foot, and the foot switch includes a wiring connector that electrically connects or disconnects the laser light source and the foot switch.

[0014] According to this, the laser pointer has a foot switch equipped with a wiring connector that electrically connects or disconnects the laser light source and the foot switch, so when the worker moves around during work, the laser light source attached to the worker's head can be disconnected from the foot switch placed at the worker's feet, allowing the worker to move easily. In other words, this laser pointer can reduce the disruption of the worker's work caused by the movement of the laser pointer.

[0015] Another feature of the present invention is that in the laser pointer, the foot switch wiring electrically connecting the laser light source and the foot switch is long enough from the laser light source to the wiring connector to enable the wiring connector to be positioned behind the operator when the laser light source is attached to the operator's head by the head-mounted device.

[0016] According to this, when the laser light source of the laser pointer is attached to the head of the worker using the head-mounted device, the length of the foot switch wiring from the laser light source to the wiring connector is long enough to position the wiring connector behind the worker. With a laser pointer configured in this way, if the worker moves while working, the worker can ask someone nearby to connect or disconnect the laser light source and the foot switch behind the worker in parallel with the worker's movement. In other words, this laser pointer allows the connection work to be performed behind the worker in parallel with the worker's movement, thereby reducing interference with the worker's work.

[0017] Furthermore, the present invention can be embodied not only as an invention of a laser pointer, but also as an invention of a method of attaching a laser pointer to a worker.

[0018] Specifically, the method for wearing a laser pointer is a method for wearing a laser pointer that is attached to the head of a worker and includes a laser light source that emits laser light, a head mounting device for attaching the laser light source to the head of a worker, a functional unit that has at least one of the functions of causing the laser light source to emit or stop laser light and of supplying power, and wiring for the functional unit that electrically connects the laser light source and the functional unit, and when the laser light source is attached to the head of the worker by the head mounting device, the functional unit can be positioned on the back side of the worker.

[0019] According to this, the laser pointer wearing method can be expected to have the same effects as the above-mentioned laser pointer invention. Specifically, in this laser pointer wearing method, the functional unit is worn so as to be located behind the worker, so that when the worker wants to cause the laser light source to emit or stop laser light, the worker can ask someone nearby to turn the laser pointer on and off behind the worker without interrupting their work. In other words, according to this laser pointer wearing method, the laser pointer can be turned on and off behind the worker in parallel with the worker's work, thereby reducing interference with the worker's work.

[0020] Furthermore, with this laser pointer wearing method, if the power of the power source drops during work, the worker can ask someone nearby to replace the battery behind the worker, without having to remove the laser light source from the worker's head. In other words, with this laser pointer wearing method, the power source can be replaced behind the worker while the worker is working, thereby reducing interference with the worker's work.

[0021] [Figure 1] 1 is a perspective view schematically illustrating an outline of the overall configuration of a laser pointer according to an embodiment of the present invention. [Figure 2] 2 is a diagram schematically illustrating a usage mode of the laser pointer shown in FIG. 1. FIG. [Figure 3] 2 is a block diagram showing an outline of the flow of power to the laser pointer shown in FIG. 1. FIG. DETAILED DESCRIPTION OF THE INVENTION

[0022] An embodiment of a laser pointer 100 according to the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view schematically illustrating the overall configuration of a laser pointer 100 according to one embodiment of the present invention. FIG. 2 is a view schematically illustrating how the laser pointer 100 shown in FIG. 1 is used. Note that the drawings referred to in this specification are schematic, with some components exaggerated to facilitate understanding of the present invention. Therefore, the dimensions and proportions of the components may differ. The laser pointer 100 is worn on the head of a worker W (e.g., a doctor, a resident, or a nurse) performing a task such as surgery, and is used to point to a specific location with a laser beam spot.

[0023] (Configuration of laser pointer 100) As shown in FIG. 1, this laser pointer 100 is mainly composed of a head-mounted device 101, a laser light source 120, a functional box 130, a back-mounted device 140, a first wiring 150, a second wiring 160, and a foot switch 170.

[0024] The head mounting device 101 is a device for mounting the laser light source 120 on the head of the worker W, and is mainly composed of a mounting device main body 102, a light source connecting part 103, and a face shield part 110.

[0025] The wearing device main body 102 is a component for attaching the light source connector 103 to the head of the worker W, and is configured by molding a resin material into a U-shape in a plan view. More specifically, the wearing device main body 102 is configured as a single piece in which one forehead hook part 102a that is placed over the forehead of the worker W and supported on this forehead, and two ear hook parts 102b that are hung over the left and right ears of the worker W, respectively, are continuously connected.

[0026] In this case, the front head strap portion 102a extends a length (width) slightly longer than the width of the face of the worker W and is formed in a shape that gradually hangs down and curves from the longitudinal center portion to both ends. The two ear strap portions 102b extend in the same direction from both ends of the front head strap portion 102a and are then formed in a J-shape that curves gently downward. A connecting portion 102c is formed at the boundary between each of the two ear strap portions 102b and the front head strap portion 102a.

[0027] The connecting portion 102c is a part for detachably connecting the light source connecting portion 103 and the face shield portion 110, and is configured with two through holes aligned in the direction in which the ear hook portion 102b extends (the front-to-back direction of the worker W).

[0028] The light source connector 103 is a component for attaching the laser light source 120 to the attachment body 102. Specifically, the light source connector 103 is configured to include a metal or resin ball joint 104, which has a connector pin 104a formed at one end thereof and a light source gripper 104b formed at the other end thereof.

[0029] The connecting pin portion 104a is a portion that is detachably connected to the attachment main body 102, and is formed in a round rod shape. The light source gripping portion 104b is a portion for holding the laser light source 120, and is formed in a C-shaped claw shape with a cross section into which the laser light source 120 detachably fits. With these, the light source connecting portion 103 holds the laser light source 120 in a state where the orientation of the laser light source 120 can be freely changed within the movable range of the ball joint 104.

[0030] The face shield part 110 is a part for protecting the face from splashes of bodily fluids or dust, and is mainly composed of a shield support part 111 and a shield 112.

[0031] The shield support part 111 is a resin part for holding the shield 112 in front of the face of the worker W, and is formed in a rod shape that extends in a U-shape in plan view. The shield support part 111 has projections on both ends that project inward, and these projections fit into the through-hole in front of the worker W, one of the two through-holes that make up the connecting part 102c of the wearing tool main body 102.

[0032] Furthermore, the bottom portion of the U-shaped shield support part 111 is positioned to protrude forward relative to the wearing device main body 102 and holds the shield 112. Specifically, five protrusions are formed along the longitudinal direction of the bottom portion of the shield support part 111, and these protrusions fit into through holes formed in the shield 112 to hold the shield 112. This allows the shield support part 111 to rotate around the two protrusions as the rotation center, and the shield 112 can be positioned at any position between in front of and above the face of the worker W.

[0033] The shield 112 is a shield that is placed in front of the face of the worker W to cover part of the face, and is made of a transparent resin plate. In this embodiment, the shield 112 is formed to a size that covers the forehead, the area around both eyes, and the cheekbones of the worker W (i.e., the upper half of the face of the worker W) when placed in front of the face of the worker W. Five through-holes are formed in the upper part of the shield 112 along the width direction, and the shield 112 is attached to the shield support part 111 via these through-holes. In this embodiment, the shield 112 is attached to the shield support part 111 with both ends curved.

[0034] The laser light source 120 is a device for emitting laser light, and has an outer shape formed in a round bar shape. In this case, the laser light source 120 formed in a round bar shape emits laser light from one end, and a first wiring 150 extends from the other end. In this embodiment, the laser light source 120 is configured to include a light source that emits a single linear red laser beam. This laser light source 120 is held by the light source gripping portion 104b of the light source connecting portion 103 so as to emit laser light in front of the face of the worker W.

[0035] The laser light source 120 may be any light source that emits a beam of light sufficient to point to a specific position, and the type, output, irradiation distance, shape or color of the laser beam may be determined appropriately depending on the usage environment, etc. For example, the laser light source 120 may be configured as a light source that emits green laser light in a cross shape. The laser light source 120 is electrically connected to the power supply unit 131 in the function unit box 130 via the first wiring 150.

[0036] The functional unit box 130 is a device for supplying power to the laser light source 120, and as shown in Fig. 3, is configured to include a power supply unit 131 and a light source switch 132 in a box-shaped resin housing. In this embodiment, the functional unit box 130 is formed to be small enough to be held in one hand. The power supply unit 131 and the light source switch 132 in the functional unit box 130 correspond to the functional unit according to the present invention. In addition, a back attachment 140 is attached to the functional unit box 130.

[0037] The power supply unit 131 is an electric circuit equipped with a battery 131a that supplies power to the laser light source 120 via the light source switch 132 and the foot switch 170. This power supply unit 131 converts the power output from the battery 131a into power for driving the laser light source 120 and outputs the power. In this case, the battery 131a is configured as a primary battery that cannot be charged and only discharges. The battery 131a is detachably attached to the power supply unit 131.

[0038] The light source switch 132 is a switching device that switches between supplying and stopping power to the laser light source 120. That is, the light source switch 132 has a function of causing the laser light source 120 to emit or stop laser light by switching between supplying and stopping power to the laser light source 120. In this embodiment, the light source switch 132 is configured as a so-called slide switch that has an operator that can be switched between ON and OFF by sliding it manually. Note that the light source switch 132 is not limited to this embodiment, and can be configured as, for example, a toggle switch, a rocker switch, a push button switch, a rotary switch (dial), or the like.

[0039] The back attachment device 140 is a device for detachably attaching the functional box 130 to the back of the worker W. In this embodiment, the back attachment device 140 is configured as a clip that can hold the functional box 130 by clamping the clothing of the worker W with the elastic force of a torsion spring. The back attachment device 140 is tied to the functional box 130 with a string.

[0040] The first wiring 150 is an electric wire for supplying power from the power supply unit 131 to the laser light source 120. One end of this first wiring 150 extends from the laser light source 120, and the other end is electrically connected to the function unit box 130 via a connection terminal 150a. In this embodiment, the first wiring 150 is formed to a length that allows the function unit box 130 to be positioned on the back side of the worker W when the laser light source 120 is attached to the head of the worker W by the head-mounted device 101. More specifically, the first wiring 150 is formed to a length that allows the back-mounted device 140 to be attached to the neck part of the clothing of the worker W when the laser light source 120 is attached to the head of the worker W. This first wiring 150 corresponds to the function unit wiring according to the present invention.

[0041] The second wiring 160 is an electric wire for supplying power from the power supply unit 131 to the laser light source 120 via the foot switch 170. In this embodiment, the second wiring 160 is configured such that one end extends from the function unit box 130 and the other end is electrically connected to the foot switch 170. This second wiring 160 includes a wiring connector 161.

[0042] The wire coupler 161 is a component for connecting or separating the second wires 160 together midway along the second wires 160, and is configured by a connector. Here, when the laser light source 120 is attached to the head of the operator W by the head-mounted device 101, the lengths of the first wires 150 and the second wires 160 from the laser light source 120 to the wire coupler 161 are formed to be long enough to position the wire coupler 161 on the back side of the operator W. This second wire 160 corresponds to the foot switch wire according to the present invention.

[0043] The foot switch 170 is a switching device that is operated by the operator W with his foot to switch between supplying and stopping power to the laser light source 120. The foot switch 170 can be configured as a so-called momentary type that is ON only while pressed with the foot and switches OFF when the foot is released. The foot switch 170 can also be configured as a so-called alternate type that switches ON and OFF each time it is pressed with the foot. In this embodiment, the foot switch 170 is configured as a momentary type.

[0044] (Laser pointer 100 attached) Next, we will explain how to wear the thus configured laser pointer 100. In this embodiment, the laser pointer 100 is worn and used by a worker W, such as a doctor, a medical intern, or a nurse, involved in surgery.

[0045] First, the worker W prepares the head mounting device 101 and the laser light source 120. In this case, the light source connector 103 and the face shield part 110 are attached to the head mounting device 101 and the mounting device main body 102. Specifically, the light source connector 103 is connected to one of the two through-holes constituting the connector 102c on the left side of the worker W in the mounting device main body 102, which is located behind the worker W. In addition, the face shield part 110 is connected to two through-holes in front of the worker W, which are located behind the worker W, of the four through-holes constituting the connectors 102c on both sides in the mounting device main body 102.

[0046] Next, the worker W attaches the laser light source 120 to the head mounting device 101. Specifically, the worker W fits the laser light source 120 into the light source gripping portion 104b of the light source connecting portion 103 so that the laser light source 120 emits laser light in front of the worker W's face.

[0047] Next, the worker W puts the head mounting device 101, to which the laser light source 120 is attached, on the head of the worker W. Specifically, the worker W puts the ear hook parts 102b of the mounting device main body 102 over both the left and right ears of the worker W, and places the forehead hook part 102a against the forehead of the worker W to mount the head mounting device 101.

[0048] Next, worker W changes into surgical clothing and prepares for surgery. Specifically, worker W washes his or her hands to make them clean, and puts on a sterilized mask, gloves, and surgical gown. In this case, worker W puts on the surgical gown with the assistance of person A (e.g., a doctor, a medical intern, or a nurse) around worker W.

[0049] Here, during surgery, it is necessary to clearly separate areas that are touched only by sterilized instruments, tools, or clean workers W (workers W wearing sterilized masks, gloves, and surgical gowns) (hereinafter referred to as "clean areas") from other areas (hereinafter referred to as "non-clean areas"), mainly to prevent postoperative patient P from contracting an infectious disease.

[0050] Therefore, the back side of the worker W that has been touched by the surrounding person A becomes an unclean area, and the chest side and forearm area where the worker W will perform surgery become clean areas. Therefore, in the subsequent work of attaching the laser pointer 100, the worker W mainly asks the surrounding person A to help with the attachment work in order to keep the clean area clean.

[0051] Next, the worker W, with the assistance of the surrounding person A, attaches the functional unit box 130 to the back side of the worker W. First, the surrounding person A prepares the functional unit box 130 to which the back attachment 140 is attached. In this case, the surrounding person A sets the battery 131a in the power supply unit 131.

[0052] Next, the surrounding person A clamps the collar of the clothing of the worker W with the back harness 140 and attaches the back harness 140 to the neck portion of the worker W. This allows the worker W to attach the function unit box 130 to the back side (non-clean area) opposite to the chest side (clean area) where surgery is performed. Here, the clothing worn by the worker W may be, for example, a medical scrub or a surgical gown worn as the outermost garment during surgery.

[0053] Next, the worker W, with the assistance of the surrounding person A, sets the light source switch 132 to a usable state. Specifically, the surrounding person A connects the connection terminal 150a of the first wiring 150, which hangs down from the laser light source 120 and is located on the back side of the worker W, to the function unit box 130. As a result, the surrounding person A can operate the light source switch 132 on the back side of the worker W to make the laser light source 120 emit laser light (hereinafter also referred to as "start operation") or stop (hereinafter also referred to as "stop operation").

[0054] Next, the worker W adjusts the orientation of the laser light source 120 with the assistance of the surrounding person A. First, the surrounding person A operates the light source switch 132 to emit laser light from the laser light source 120. Next, the surrounding person A adjusts the orientation of the laser light source 120 relative to the attachment main body 102 as desired by the worker W, referring to the position of the light spot of the laser light. In this case, the surrounding person A can change the orientation of the laser light source 120 within the movable range of the ball joint 104 by grasping the laser light source 120 and moving it up and down or left and right.

[0055] Furthermore, the worker W positions the shield 112 with the assistance of the surrounding person A. Specifically, the surrounding person A pushes up or down the shield support part 111 to rotate it around two protrusions provided on both ends of the shield support part 111, thereby placing the shield 112 at any position on the worker W between in front of and above the face of the worker W.

[0056] Next, the worker W, with the assistance of the nearby person A, puts the foot switch 170 into a usable state. First, the nearby person A places the foot switch 170 on the floor where the feet of the worker W will be placed when the worker W performs surgery. In this case, the worker W can also adjust the position of the foot switch 170 by moving the foot switch 170 with his or her foot.

[0057] Next, the bystander A electrically connects the function unit box 130 and the foot switch 170. Specifically, the bystander A connects one terminal of the wire connector 161 of the second wiring 160 hanging down from the function unit box 130 and positioned on the back side of the worker W to the other terminal of the wire connector 161 of the second wiring 160 extending from the foot switch 170 on the back side of the worker W. By performing these operations, the worker W can wear the laser pointer 100.

[0058] On the other hand, when removing the laser pointer 100, the worker W first, with the assistance of the surrounding person A, pulls out the connection terminal 150a from the functional unit box 130 to separate the laser light source 120 from the functional unit box 130. Next, with the assistance of the surrounding person A, the worker W removes the back-worn device 140 from the collar of the worker W's clothing, thereby removing the functional unit box 130 from the worker W's clothing. Next, with the assistance of the surrounding person A, the worker W removes the head-worn device 101 from the worker W's head. By performing these steps, the worker W can remove the laser pointer 100. Note that if the surgery has already ended when these removal steps are performed, the worker W can naturally remove the laser pointer 100 by himself.

[0059] (Activation of laser pointer 100) Next, the operation of the laser pointer 100 attached in this manner will be described. This laser pointer 100 is attached to the head of the worker W performing the work and is used to point to a specific location with a laser light spot. In this embodiment, the laser pointer 100 is used in various surgeries performed in obstetrics and gynecology using medical equipment such as an endoscope or medical electrical equipment such as a laser treatment device.

[0060] First, the worker W prepares the head-mounted device 101, the laser light source 120, the functional box 130 equipped with the back-mounted device 140, and the foot switch 170, and then attaches them using the above-mentioned mounting method.

[0061] Next, the worker W uses the laser pointer 100 to point to a specific position. First, the worker W causes the laser light source 120 to emit laser light. Specifically, the worker W causes the laser light source 120 to emit laser light by continuing to press the foot switch 170 with his foot. In this case, while the foot switch 170 is being pressed by the worker W, the foot switch 170 continuously supplies power to the laser light source 120 via the first wiring 150 and the second wiring 160. This causes the laser light source 120 to start operating.

[0062] Next, the operator W moves his / her head so that the light spot of the emitted laser light is located at the desired location. By performing these operations, the operator W can use the laser pointer 100 to point to a desired location during surgery, and can, for example, give guidance, instructions, requests, or attention to the person A around him / her. In this embodiment, the operator W can provide guidance to the person A around him / her by positioning the light spot of the laser light at the desired location in the surgical field (i.e., the area visible to the eyes performing the surgery) displayed on the monitor M located in front of the operator W. Here, the monitor M is a display device that displays an image on a display screen based on information from a camera (not shown) that photographs the operating table T on which the patient P is lying from above.

[0063] Next, when the operator W wants to stop the laser light source 120 from emitting laser light, he or she removes his or her foot from the foot switch 170. In this case, the foot switch 170 stops the supply of power to the laser light source 120. This causes the laser light source 120 to stop operating.

[0064] On the other hand, if the power level of the laser pointer 100 decreases during surgery, the worker W replaces the battery. Specifically, the worker W asks a nearby person A to replace the battery 131a in the power supply unit 131. In this case, the nearby person A can replace the battery 131a without removing the functional unit box 130. Alternatively, the nearby person A can replace the battery 131a by removing only the functional unit box 130. Specifically, the nearby person A can remove the back-worn device 140 from the clothing of the worker W and remove only the functional unit box 130 by disconnecting the laser light source 120 and the functional unit box 130 from the functional unit box 130. In either case, the worker W can replace the battery 131a on the back side of the worker W without removing the laser light source 120 or moving the foot switch 170.

[0065] In this case, after replacing the battery, the bystander A can check whether the laser light source 120 is operating normally by operating the light source switch 132. In this case, since the bystander A operates the light source switch 132 from behind the operator W, it is possible to reduce the interference of the bystander A's operation with the operation of the laser light source 120.

[0066] Furthermore, when the operator W moves during surgery, the nearby person A, upon receiving a request from the operator W, moves the foot switch 170 placed on the floor to a predetermined position. First, the nearby person A separates the wire connector 161 located on the back side of the operator W into its respective terminals, thereby separating the function unit box 130 and the foot switch 170. This allows the operator W to move quickly after the wire connector 161 is separated, without having to wait for the foot switch 170 to be placed at its destination.

[0067] Next, bystander A places foot switch 170 on the floor where worker W's feet will be at the destination. In this case, worker W can also adjust the position of foot switch 170 by moving foot switch 170 with his / her foot. Next, bystander A connects the terminals of wire connector 161 on the back side of worker W to connect function unit box 130 and foot switch 170. By performing these operations, worker W can move during surgery.

[0068] As can be understood from the above description of operation, according to the above embodiment, when the laser light source 120 is attached to the head of the worker W by the head-mounted device 101, the first wiring 150 (wiring for the functional unit) is formed to a length that enables the functional unit box 130, which includes the power supply unit 131 and the light source switch 132, to be located behind the worker W. Therefore, when the worker W wants to cause the laser light source 120 to emit or stop laser light in the laser pointer 100, the worker W can ask a nearby person A to turn the laser pointer 100 on and off behind the worker W without interrupting his or her work. In other words, the laser pointer 100 can be turned on and off behind the worker W in parallel with the worker W's work, thereby reducing interference with the worker W's work.

[0069] Furthermore, in the case where the power of power supply unit 131 in laser pointer 100 decreases during work, worker W can ask nearby person A to replace battery 131a at the back side of worker W, without removing laser light source 120 from the head of worker W. In other words, since the laser pointer 100 allows the replacement of battery 131a at the back side of worker W in parallel with the work being performed by worker W, it is possible to reduce interference with the work of worker W.

[0070] Furthermore, the present invention is not limited to the above-described embodiment, and various modifications are possible without departing from the object of the present invention.

[0071] For example, in the above embodiment, the head mounting device 101 is configured to include the face shield portion 110. This allows the laser pointer 100 to attach the laser light source 120 and the shield 112 to the head of the operator W using a single device (the mounting device main body 102 in the above embodiment), improving wearability. However, the head mounting device 101 can also be configured without the face shield portion 110.

[0072] In this case, since the connecting portion 102c of the wearing device main body 102 of the head wearing device 101 is configured with two through holes, the connecting position of the light source connector 103 relative to the wearing device main body 102 can be selected arbitrarily. That is, when connecting the light source connector 103 to the wearing device main body 102, the worker W can select one of the two through holes configuring the connecting portion 102c on the front or rear side of the worker W to connect the light source connector 103. According to this, since the wearing device main body 102 has a plurality of connecting portions 102c for connecting the light source connectors 103 formed side by side in the front-to-rear direction of the worker W, the connecting position of the laser light source 120 can be selected arbitrarily in the front-to-rear direction of the worker W.

[0073] In the above embodiment, the wearing device main body 102 is formed by molding a resin material into a U-shape in a plan view. However, the wearing device main body 102 is not limited to the above embodiment, and can also be formed, for example, by eyeglasses, sunglasses, a hat, a helmet, or a headband that is worn and fixed around the head circumference of the worker W.

[0074] In the above embodiment, the light source connector 103 is configured to include the ball joint 104, the connector pin 104a, and the light source gripper 104b. This allows the laser pointer 100 to freely change the orientation of the laser light source 120 relative to the attachment body 102 within the movable range of the ball joint 104. However, the light source connector 103 can also be configured without the ball joint 104.

[0075] In this case, the light source connector 103 can be configured to include a hinge that connects the laser light source 120 to the mounting device main body 102 so that the laser light source 120 can be rotated in the front-to-rear direction of the worker W. The light source connector 103 can also be configured as an integrated unit by connecting the connecting pin portion 104a and the light source gripping portion 104b to both ends of a round bar material, thereby fixedly connecting the laser light source 120 to the mounting device main body 102.

[0076] Furthermore, in the above embodiment, the light source connector 103 is mainly configured to include the ball joint 104. However, the light source connector 103 is not limited to the above embodiment. For example, the light source connector 103 can be configured to be formed into a ring shape with an O-shaped or C-shaped cross section into which the ear hook portion 102b of the wearing device main body 102 can be detachably fitted. Furthermore, the light source connector 103 can also be configured to be attached to the wearing device main body 102 by adhesive tape, hook-and-loop fasteners, magnets, clips, safety pins, or buttons.

[0077] In the above embodiment, the back attachment device 140 is configured as a clip. However, the back attachment device 140 is not limited to the above embodiment and can be configured as, for example, an adhesive tape, a hook-and-loop fastener, a magnet, a hook and eye fastener, a snap button, or a safety pin. The back attachment device 140 can also be configured to be attached by hooking onto a button on the clothing of the worker W or by sandwiching the clothing of the worker W between two members from the inner and outer fabric sides.

[0078] In the above embodiment, the back-worn device 140 is configured as a clip that can hold the clothing of the worker W and support the function unit box 130. This allows the power supply unit 131 and the light source switch 132 of the laser pointer 100 to be attached to the clothing of the worker W. However, the back-worn device 140 may be any device that can attach at least the power supply unit 131 or the light source switch 132 to the back side of the worker W.

[0079] For example, the back attachment device 140 can be configured with two clips that can attach the power supply unit 131 and the light source switch 132 separately to the clothing of the worker W. Alternatively, the back attachment device 140 can be configured with one clip that is provided on either the power supply unit 131 or the light source switch 132 and can attach only the power supply unit 131 or the light source switch 132 to the clothing of the worker W.

[0080] In the above embodiment, the back-worn device 140 is configured to be able to support the function unit box 130 on the back side of the worker W. This allows the back-worn device 140 of the laser pointer 100 to be positioned on the back side of the worker W, thereby reducing interference with the work of the worker W caused by the work of attaching or detaching the back-worn device 140. In addition, by positioning the back-worn device 140 on the back side opposite the chest side where the work is performed by the worker W, the laser pointer 100 can reduce interference with the work caused by the attached back-worn device 140.

[0081] In particular, in the above embodiment, the back-worn device 140 of the laser pointer 100 can be positioned in a non-clean area rather than a clean area, and therefore the functional unit box 130 can be attached to the clothing of the worker W without contaminating the clean area with the back-worn device 140. On the other hand, if it is not necessary to clearly separate the clean area and the non-clean area in the work of the worker W, the back-worn device 140 can also be configured as a band that is wrapped around the worker W's body, such as around the worker W's waist or arm.

[0082] In the above embodiment, the back-worn device 140 is configured to be attached to the neck area of ​​the worker W's clothing, specifically, the collar. This makes it easy to attach the functional unit box 130, which includes the power supply unit 131 and the light source switch 132, to the worker W's clothing and to maintain the attached state. Furthermore, the back-worn device 140 of the laser pointer 100 can be attached to the neck area of ​​the worker W's clothing so that the functional unit box 130 can be supported on the worker W's shoulders, thereby reducing discomfort or damage to the clothing caused by the weight of the functional unit box 130 pulling on the clothing. However, the back-worn device 140 can also be configured to be attached to a part of the worker W's back other than the neck area of ​​the worker W's clothing, such as the waist or buttocks.

[0083] In the above embodiment, the back attachment 140 is attached to the functional unit box 130 with a string and configured to be separable. This allows the back attachment 140 of the laser pointer 100 to be easily replaced or changed. However, the laser pointer 100 can also be configured to be integrally formed with the functional unit box 130.

[0084] In the above embodiment, the laser pointer 100 is configured to include the back-worn device 140. However, the laser pointer 100 can be configured without the back-worn device 140. In this case, when the laser light source 120 is attached to the head of the worker W, the laser pointer 100 is disposed in a state in which the function unit box 130 is suspended from the laser light source 120 on the back side of the worker W by the first wiring 150. Furthermore, when the laser light source 120 is attached to the head of the worker W, the laser pointer 100 can also be placed in a state in which the function unit box 130 is sandwiched between the collar of the worker W's clothing and the worker's neck.

[0085] In the above embodiment, the laser pointer 100 is configured such that the power supply unit 131 and the light source switch 132 are housed in a single housing. This makes it easy to attach the laser pointer 100 because the power supply unit 131 and the light source switch 132 are housed in a single housing. However, the laser pointer 100 can also be configured such that the power supply unit 131 and the light source switch 132 are separated and separately configured. In this case, the power supply unit 131 can be configured to be provided inside the laser light source 120.

[0086] In the above embodiment, the functional unit of the laser pointer 100 is configured by the power supply unit 131 and the light source switch 132. However, the functional unit is not limited to the above embodiment, and may be configured by, for example, either the power supply unit 131 or the light source switch 132.

[0087] The functional unit may also be configured as a control device that controls the start or stop of operation of the laser light source 120 based on a signal output from an input device that accepts external operations. In this case, the input device may be configured as, for example, a microphone, a touch panel that accepts input by tapping, a camera that accepts input by gestures or hand movements using image recognition, a keyboard, a mouse, a foot switch, a slide switch, or a sensor. In this case, the control device may be configured as a microcomputer.

[0088] The functional unit may also be configured as a connector that can connect or disconnect wires to each other. In this case, the laser pointer 100 may be configured to include a connector in the middle of the wire that electrically connects the laser light source 120 and the power supply unit 131, and to start operation of the laser light source 120 by connecting the respective terminals that make up the connector, and to stop operation of the laser light source 120 by separating the terminals from each other.

[0089] In the above embodiment, the power supply unit 131 is configured to include the battery 131a, which is a primary battery. However, the power supply unit 131 can use a battery other than a primary battery as the battery 131a. For example, the battery 131a can be a secondary battery that can be repeatedly charged and discharged, a solar cell, or a combination of these batteries. The laser pointer 100 can also be configured to be powered by an external power source, such as a household 100V power supply, instead of or in addition to the battery 131a. In this case, the power supply unit 131 can be configured to include a conversion adapter that converts power supplied from the external power source into power for driving the laser light source 120.

[0090] Furthermore, in the above embodiment, power supply unit 131 is configured so that power is supplied from battery 131a to light source switch 132 without going through the power switch. However, power supply unit 131 can also be configured so that power from battery 131a is supplied to light source switch 132 and foot switch 170 via the power switch. This allows laser pointer 100 to reduce power consumption of battery 131a by turning off the power switch when not in use, such as during storage.

[0091] Furthermore, in the above embodiment, the laser pointer 100 is configured such that the light source switch 132 and the foot switch 170 are connected in parallel to the laser light source 120. However, the laser pointer 100 can also be configured such that the light source switch 132 and the foot switch 170 are connected in series to the laser light source 120. In this case, the laser pointer 100 can start or stop the operation of the laser light source 120 by operating the foot switch 170 with the light source switch 132 turned on.

[0092] In the above embodiment, the laser pointer 100 is configured to include both the light source switch 132 and the foot switch 170. However, the laser pointer 100 may be configured to include either the light source switch 132 or the foot switch 170.

[0093] Furthermore, in the above embodiment, the first wiring 150 and the second wiring 160 are formed to have a length from the laser light source 120 to the wiring connector 161 that allows the wiring connector 161 to be positioned behind the worker W when the laser light source 120 is attached to the head of the worker W by the head-mounted device 101. With this, when the worker W moves during work, the worker W can request a nearby person A to perform the connection work of connecting or disconnecting the laser light source 120 and the foot switch 170 behind the worker W in parallel with the worker W's movement. In other words, the laser pointer 100 can perform the connection work behind the worker W in parallel with the worker W's movement, thereby reducing interference with the worker W's work.

[0094] However, the first wiring 150 and the second wiring 160 can be configured so that when the laser light source 120 is attached to the head of the worker W by the head mounting device 101, the length from the laser light source 120 to the wiring connector 161 is different from the length that allows the wiring connector 161 to be positioned on the back side of the worker W. Specifically, the first wiring 150 and the second wiring 160 can be configured so that when the laser light source 120 is attached to the head of the worker W by the head mounting device 101, the length from the laser light source 120 to the wiring connector 161 is a length that allows the wiring connector 161 to be positioned on the chest side of the worker W.

[0095] In the above embodiment, the second wiring 160 is configured to include the wiring connector 161. This allows the laser pointer 100 to be easily moved by separating the laser light source 120 and the foot switch 170 when the operator W moves during work. However, the second wiring 160 can be configured without the wiring connector 161.

[0096] In the above embodiment, the foot switch 170 is connected to the power supply unit 131 via the second wiring 160. This allows the laser pointer 100 to start or stop the operation of the laser light source 120 using the foot switch 170 even in situations where devices that emit radio waves cannot be used, such as during medical examinations, tests, or surgery using electrical medical equipment. However, if the laser pointer 100 is configured to include the control device, the foot switch 170 can be wirelessly connected to the control device to control the operation of the laser light source 120.

[0097] In the above embodiment, laser pointer 100 is worn by operator W while head-mounted device 101, laser light source 120, function unit box 130, and foot switch 170 are connected via first wiring 150 and second wiring 160. However, the method of wearing laser pointer 100 is not limited to that in the above embodiment, and an appropriate method can be selected depending on the environment in which laser pointer 100 is used, the type of work, the situation of operator W, and the like.

[0098] Specifically, the laser pointer 100 can be worn by connecting the head-mounted device 101, the laser light source 120, the function unit box 130, and the foot switch 170, and then attaching the connected laser pointer 100 to the operator W. In the above embodiment, the operator W can wash his or her hands to keep them clean and put on a sterilized mask, gloves, and surgical gown at any time desired by the operator W.

[0099] In the above embodiment, the laser pointer 100 was attached to the worker W performing surgery. However, the laser pointer 100 can be attached to the head of the worker W performing the work and used in a wide range of situations where it points to a specific location with a laser beam spot. Therefore, the situations are not limited to those in the above embodiment, and can include situations where the worker W provides guidance, instructions, requests, or calls attention to a nearby person A in educational settings such as a school or cram school, a construction site, a factory, a kitchen, etc. [Explanation of symbols]
