Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to an auxiliary lighting device. Background Art

[0002] Currently, dermatological laser therapy devices are widely used, but there is a common problem of lack of auxiliary lighting system, which seriously affects the treatment effect and efficiency.

[0003] Among them, when the handpiece contacts the skin, it produces a shadow that blocks the line of sight. Especially when treating skin lesions with complex contours or hidden locations, the shadow effect makes it difficult to accurately distinguish the lesions from normal skin. The laser therapy device's built-in indicator light is too strong or too weak, which will cause a decrease in the contrast between the lesions and normal skin, affect the aiming of the treatment path, and easily cause operational deviations. The lighting facilities in some treatment sites cannot meet the needs of high-definition vision, especially in darkroom conditions. The local poor lighting causes the lesion boundaries to be blurred, increasing the risk of misoperation.

[0004] To address these issues, short-range lighting equipment such as flashlights and floor lamps are often used in clinical practice. However, these devices are inconvenient to use, require assistance from others, and cannot move synchronously with the treatment handpieces, further restricting the efficiency of treatment.

For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0023] Combine the following Figure 1-Figure 2 The specific implementation of the auxiliary lighting device of the present utility model is described.

[0024] The utility model provides an auxiliary lighting device, which aims to solve the problem of lack of auxiliary lighting system commonly existing in the current dermatology laser treatment instrument. This problem leads to significant shadow of treatment handpiece, improper regulation of laser beam indicator light and poor lighting conditions in the treatment environment during the treatment process, which seriously affects the accuracy and efficiency of the treatment. The auxiliary lighting device includes: a lamp head 10, in which an LED lamp for providing lighting light is arranged; a clamp, including a base 20 and a first clamp 21 and a second clamp 22 relatively arranged on the base 20, the clamp has a clamping state and a release state, in the clamping state, the first clamp 21 and the second clamp 22 are close to each other, in the release state, the first clamp 21 and the second clamp 22 are far away from each other, and a locking mechanism for keeping the clamp in the clamping state is arranged between the first clamp 21 and the second clamp 22; a flexible neck tube 11, connected between the lamp head 10 and the base 20, and the flexible neck tube 11 has the freedom to bend in any direction. By applying the auxiliary lighting equipment of the utility model, accurate lighting assistance can be achieved for the lesion area during laser treatment, which can improve the accuracy of the doctor's judgment on the treatment path and reduce misoperation caused by insufficient lighting, thereby improving the treatment effect and efficiency, while also ensuring the safety of the treatment process.

[0025] Specifically, an LED lamp is integrated inside the lamp head 10. With its advantages of high efficiency, long life and adjustable light color, the LED lamp provides stable and suitable brightness lighting for the treatment area, ensuring that the doctor can clearly observe the subtle differences between the skin lesions and the surrounding normal skin, which is conducive to accurately positioning the laser treatment point. Through the flexible flexible neck tube 11, the direction of the lamp head 10 can be adjusted at any time according to the treatment needs to provide targeted local lighting. The clamp includes a base 20 and a first clamp 21 and a second clamp 22 arranged on both sides of the base 20. The two clamps can move relative to each other to form a clamping state and a release state. Among them, in the clamping state, the first clamp 21 and the second clamp 22 are close to each other and fixed by a locking mechanism to firmly clamp a specific part of the treatment handpiece, ensuring that the auxiliary lighting device is closely connected to the treatment handpiece and will not loosen or fall off during the treatment process. In the release state, the locking mechanism is unlocked, so that the first clamp 21 and the second clamp 22 can be separated from each other, which is convenient for quickly installing or disassembling the auxiliary lighting device on different treatment handpieces to meet the needs of different treatment scenarios.

[0026] The presence of the above-mentioned locking mechanism ensures that the clamp can maintain a stable clamping force in the clamped state, ensures that the auxiliary lighting device is firmly connected to the treatment handpiece, and is not easy to separate even if slightly disturbed by external force during the treatment operation. According to design requirements and application scenarios, the locking mechanism can adopt different types of implementation methods to meet different levels of stability and operational convenience requirements. On the one hand, the locking mechanism can be designed as an elastic locking device. Such devices usually use springs, elastic materials or other elastic components to achieve locking between clamps through preload force or deformation energy storage. On the other hand, in order to obtain a higher level of stability and reliability, the locking mechanism may preferably be a mechanical locking mechanism. Such mechanisms usually include mechanical transmission or fixing elements such as gears, ratchets, buckles, and threads, and ensure that the clamping state of the clamp is durable and stable through mechanical interlocking or fixing methods.

[0027] One or both of the first clamp 21 and the second clamp 22 can be set as a movable structure. Preferably, according to an auxiliary lighting device provided by the utility model, the first clamp 21 is fixed to the base 20, and the second clamp 22 is swingably installed on the base 20. When it is necessary to clamp the treatment handpiece, the operator drives the second clamp 22 to move closer to the first clamp 21 by manually operating the locking mechanism until the two clamps tightly clamp the treatment handpiece. When it is necessary to release the treatment handpiece, the operator releases the constraint of the locking mechanism on the second clamp 22. Among them, the fixed first clamp 21 provides a stable fulcrum for the entire auxiliary lighting device. Regardless of whether the clamp is in a clamped state or a released state, or the clamping force is adjusted, the first clamp 21 always maintains its position unchanged, providing continuous support force for the clamp as a whole. Designing the first clamp 21 as a fixed structure can improve the stability of the clamp as the basic structure of the auxiliary lighting device, simplify the equipment structure, and improve durability.

[0028] According to an auxiliary lighting device provided by the utility model, the opposite sides of the first clamp 21 and the second clamp 22 are respectively provided with an arc-shaped inner edge 23; wherein, the surface of at least one side of the arc-shaped inner edge 23 is provided with an elastic cushion layer 24. wherein, the shape of the arc-shaped inner edge 23 on the opposite sides of the first clamp 21 and the second clamp 22 is intended to simulate and fit the contour of the therapeutic handpiece. when the clamp clamps the therapeutic handpiece, the arc-shaped inner edge 23 can better conform to the curved surface of the handpiece, increase the contact area, reduce stress concentration, and thus provide a more uniform and stable clamping force. the elastic cushion layer 24 further improves the contact performance and protective effect between the clamp and the therapeutic handpiece. the elastic cushion layer 24 can not only absorb the impact force and vibration generated during the clamping process, and protect the therapeutic handpiece from hard collision damage, but also reduce the wear of the clamp itself caused by the clamping force. Preferably, the surface of the elastic cushion layer 24 is set to a rough surface such as a granular surface or a corrugated surface to further increase the friction coefficient and prevent the handpiece from slipping due to external force (such as slight shaking during surgical operations) during the clamping process.

[0029] According to an auxiliary lighting device provided by the utility model, the locking mechanism includes a handle 41 and a connecting rod 42; the handle 41 is arranged on the side of the first clamp 21 facing away from the second clamp 22; the connecting rod 42 is connected between the handle 41 and the second clamp 22, and the second clamp 22 is driven to approach or move away from the first clamp 21 through the connecting rod 42 by adjusting the angle of the handle 41. The connecting rod 42 is a transmission element between the handle 41 and the second clamp 22, one end of which is connected to the handle 41 and the other end is connected to the second clamp 22, so that the swinging action of the handle 41 can be converted into the linear movement of the second clamp 22, thereby realizing the transmission and conversion of force. The handle 41 is equivalent to a lever mechanism. By changing the angle of the handle 41, the connecting rod 42 will move linearly accordingly with the swinging of the handle 41.

[0030] Preferably, when the handle 41 swings to a certain angle, interference occurs between the handle 41 and the side of the first clamp 21, forming a physical barrier, thereby fixing the position of the handle 41. At this time, the position of the connecting rod 42 and the second clamp 22 is also locked, maintaining the clamping state between the second clamp 22 and the first clamp 21. It is understandable that a temporary fixing component, such as a buckle structure, can also be provided between the side of the first clamp 21 and the handle 41 to lock the handle 41.

[0031] According to an auxiliary lighting device provided by the utility model, the handle 41 includes a support portion 43 and a toggle portion 44; the support portion 43 is supported on the outer side of the first clamp 21; the toggle portion 44 is a handle-shaped structure fixed to the support portion 43; a first hinge shaft 45 is arranged between the support portion 43 and the toggle portion 44, and one end of the connecting rod 42 is hinged to the first hinge shaft 45. The support portion 43 is always directly supported on the outer side of the first clamp 21, playing the role of supporting the handle 41 and transmitting torque. The contact surface between the support portion 43 and the outer side of the first clamp 21 is preferably an arc surface to achieve arc surface positioning between the two. A first hinge shaft 45 is arranged between the support portion 43 and the toggle portion 44, and one end of the connecting rod 42 is connected to the first hinge shaft 45 by a hinged manner, so that the swing of the handle 41 can drive the connecting rod 42 to move linearly. In the locked state, the toggle portion 44 is preferably attached to the side of the first clamp 21 to form physical contact and blocking. At this time, the direction of the force applied to the first hinge shaft 45 is located between the angle formed by the shifting portion 44 and the supporting portion 43 , thereby forming a stable and reliable locking support state.

[0032] According to an auxiliary lighting device provided by the utility model, the second clamp 22 is provided with a second hinge shaft 25 matched with the base 20; a torsion spring 26 is sleeved on the second hinge shaft 25, and the torsion spring 26 is supported between the second clamp 22 and the base 20 to provide an elastic force to keep the second clamp 22 away from the first clamp 21. The second hinge shaft 25 serves as a rotating shaft, allowing the second clamp 22 to rotate around its axis at a certain angle, thereby realizing the clamping and releasing functions of the clamp. The elastic force provided by the torsion spring 26 between the second clamp 22 and the base 20 enables the second clamp 22 to always have a tendency to move away from the first clamp 21 when the clamp is not subjected to external force (such as the handle 41 is not operated), which helps to keep the second clamp 22 in a released state when the clamp does not clamp the treatment handpiece, and facilitates the installation and removal of the treatment handpiece. When the second clamp 22 is pulled toward the first clamp 21 by the handle 41 through the connecting rod 42, so that the clamp enters the clamping state, the torsion spring 26 is compressed and stores elastic potential energy. When the therapeutic handpiece is released, the torsion spring 26 releases its stored elastic potential energy, pushing the second clamp 22 to rotate outward along the second hinge shaft 25 and restore to the initial position away from the first clamp 21. By arranging the second hinge shaft 25 and the torsion spring 26 between the second clamp 22 and the base 20, an elastic force is provided for the second clamp 22 to move away from the first clamp 21, thereby realizing the functions of automatic resetting, constant clamping force, and energy storage and release of the clamp.

[0033] According to an auxiliary lighting device provided by the utility model, a connecting rod 42 is provided with a lead screw structure 46 at one end close to the second clamp 22; the second clamp 22 is hingedly provided with a shaft sleeve 47, and the lead screw structure 46 is movably sleeved in the shaft sleeve 47 in the axial direction; a nut member 48 is provided on the lead screw structure 46, and the nut member 48 stops on the outside of the shaft sleeve 47 to limit the axial position of the shaft sleeve 47 on the lead screw structure 46. The lead screw structure 46 is movably sleeved in the shaft sleeve 47 in the axial direction, so that the connecting rod 42 can adjust its relative position with the second clamp 22 in the axial direction through the lead screw structure 46, so as to adapt to laser therapeutic instrument handpieces of different sizes and shapes. A nut member 48 is provided on the lead screw structure 46, and the nut member 48 is threadedly matched with the lead screw structure 46. The nut member 48 can be fixed at a specific position by rotating. When the nut member 48 stops at the outside of the sleeve 47, it can limit the axial position of the sleeve 47 on the screw structure 46, that is, it limits the range of change of the relative position of the connecting rod 42 and the second clamp 22. The operator can change the relative distance between the connecting rod 42 and the second clamp 22 by adjusting the position of the nut member 48 on the screw structure 46, so that the clamp can adapt to laser therapy handpieces of different sizes and shapes. By using the screw structure 46 and the sleeve 47 to cooperate between the connecting rod 42 and the second clamp 22, and equipping with an adjustable nut member 48, flexible fixation of laser therapy handpieces of different sizes and shapes is achieved, and the adaptability and fixation reliability of the equipment are enhanced.

[0034] According to an auxiliary lighting device provided by the utility model, the base 20 in each of the above embodiments is preferably provided with a partition 27; the partition 27 divides the hollow structure in the base 20 into an activity space for setting a locking mechanism and an electric control box 28 for setting a power supply element. The partition 27 divides the hollow structure of the base 20 into two independent functional areas, which is beneficial to the structural layout and functional division inside the device, and avoids mutual interference between different functional modules.

[0035] The partition 27 divides a part of the space into the activity space of the locking mechanism, providing sufficient movement space for some components of the locking mechanism (such as the connecting rod 42), ensuring that the locking mechanism can perform clamping and releasing operations smoothly and without hindrance. Another part of the space is designed as an electric control box 28, which is used to accommodate and protect the power supply components of the auxiliary lighting equipment. The partition 27 divides the interior of the base 20 into the activity space of the locking mechanism and the electric control box 28, realizing the physical separation and functional integration of the mechanical transmission part (locking mechanism) and the electrical control part (power supply component) of the equipment.

[0036] According to an auxiliary lighting device provided by the utility model, the power supply element in the electric control box 28 includes a battery, a circuit board and a wire, and the wire is connected to the lamp head 10 through a flexible neck tube 11; a power switch 31 and a charging socket 32 ​​are arranged on the surface of the base 20 at a position opposite to the electric control box 28. Among them, as a power supply unit of the device, the battery provides stable DC power for the device to ensure that the device can still work normally when there is no external power supply. Various electronic components are integrated on the circuit board, such as a power management chip, a voltage stabilizing circuit, a protection circuit, etc., which are responsible for converting, distributing and protecting the power output by the battery to ensure that the lamp head 10 is provided with a suitable voltage and current. The wire is used to connect the battery, the circuit board and the lamp head 10, and transmit the power from the electric control box 28 to the lamp head 10 to drive the LED lamp to emit light. The wire is connected to the lamp head 10 through a flexible neck tube 11. The flexible neck tube 11 not only provides a protection channel for the wire, but also enables the lamp head 10 to flexibly adjust the irradiation angle due to its flexibility to adapt to different treatment scenarios.

[0037] A power switch 31 and a charging socket 32 ​​are provided on the surface of the base 20 at a position opposite to the electric control box 28. The power switch 31 is used to control the power on and off of the device, and the operator can easily turn the device on or off by pressing the switch button. The charging socket 32 ​​is used to connect an external power source to charge the battery inside the device to ensure that the device is fully charged and can be used at any time. The design of the charging socket 32 ​​should be compatible with common charger specifications, such as Type-C charging interface, USB interface, dedicated charging base, etc., to facilitate users to perform charging operations.

[0038] The auxiliary lighting device of the utility model can be applied to a variety of common and widely used laser therapeutic devices, including but not limited to carbon dioxide laser therapeutic devices, picosecond laser therapeutic devices, ultra-picosecond laser therapeutic devices, and high-frequency electrosurgical devices. By organically combining the auxiliary lighting device with the laser therapeutic device, the operator can more clearly and accurately identify the edge and depth of the skin lesion and the surrounding normal skin during treatment, reducing misoperation caused by unclear vision, such as over-treatment or under-treatment.
