Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, and in particular to an intelligent surgical dressing change lighting device. Background Art

[0002] At present, there are few lighting lamps designed specifically for medical dressing changes. Ordinary diagnostic lamps are generally used during dressing changes. However, ordinary diagnostic lamps will produce shadows and are not suitable for fine lighting. If shadowless lamps are used, they are too expensive. U.S. Patent No. US5772313A discloses a medical lighting device that can form an annular light beam. The device is provided with a lens that can converge the light beam. The light is reflected by a reflector located between the lens and its focus, and the light converges to one point. The design of the annular light source can provide uniform lighting without increasing shadows, and can also reduce glare. In addition, during surgical dressing changes, an intelligent lighting device that can change the focus height without adjusting the lamp posture will bring great convenience to doctors. Summary of the invention

[0003] The purpose of the present invention is to provide a low-cost, easy-to-operate, sufficiently bright and shadow-free intelligent lighting device to solve the problem that ordinary lighting lamps will generate shadows during surgical dressing changes.

[0004] In order to solve the above technical problems, the present invention specifically provides the following technical solutions: The intelligent surgical dressing change lighting device comprises a main lamp and a light source and an optical mechanism therein. A first reflecting element and an annular convex lens are arranged inside the main lamp. The light source is placed between the first reflecting element and the annular convex lens. A second reflecting element is arranged on the other side of the annular convex lens. Light is emitted from the light source and then hits the first reflecting element. After being reflected by the first reflecting element, it passes through the annular convex lens to form an annular light beam, which is reflected by the second reflecting element between the annular convex lens and its focus to converge.

[0005] Specifically, a baffle is provided in the middle of the annular convex lens. The design of the baffle can make the light emitted by the main lamp annular light, and the annular light can avoid double images. The annular convex lens is thin on the outside and thick on the inside, and its cross-sectional curve is a parabola. The annular convex lens is used as a condenser, which can converge parallel light rays to one point, and can also reduce the divergence of divergent light rays. The first reflecting element is a concave mirror, and the second reflecting element is a plane mirror. The function of the first reflecting element is to change the direction of the light beam so that the light beam passes through the annular convex lens. If the position of the light source is located at the focus of the concave mirror of the first reflecting element, the light emitted by the first reflecting element is parallel light, and converges to one point after passing through the annular convex lens and the second reflecting element. The second reflecting element is a plane mirror, which has an inclination angle with the inner wall of the main lamp, and its cross-sectional shape is a circular ring. The first reflecting element, the annular convex lens, and the second reflecting element are on the same optical axis.

[0006] Specifically, a slide groove is provided on the inner wall of the main lamp, and the second reflective element is fixed to a sliding member on the slide groove. The second reflective element can move linearly on the slide groove as the sliding member moves, thereby changing the height of the focus point. There are at least two slide grooves, which are symmetrically arranged on the inner wall of the main lamp. When in use, the focus point height can be adjusted according to specific circumstances. The advantage of the device over general technologies is that the focus point height can be changed without moving the position of the lamp.

[0007] Specifically, an auxiliary lamp is arranged outside the main lamp, and there are at least two auxiliary lamps. The auxiliary lamp emits parallel light, and the auxiliary lamp can play a fill light effect. The main lamp is provided with an infrared receiver. The remote control is independent of the entire device body and is provided with an infrared transmitter. The operator can control the working state of the device only through the remote control. The remote control can control the movement of the sliding member on the slide groove, and then control the distance between the second reflective element and the annular convex lens to adjust the focus point. In addition, the distance between the auxiliary lamp and the main lamp can be adjusted by the remote control. According to different application scenarios, the position of the auxiliary lamp is changed by pressing a button to achieve fill light at different angles. During use, the position and angle of the auxiliary lamp can also be adjusted by pressing a button.

[0008] Specifically, a first groove is provided on the side of the main lamp, and an elastic protrusion is provided at the end of the first groove. One end of the rigid connector is connected in the first groove, and the other end of the rigid connector is fixedly connected to the auxiliary lamp. Second grooves are provided on both sides of the auxiliary lamp, and the elastic connector is connected in the second groove. The auxiliary lamps are connected by the elastic connector, and the second groove can accommodate at least one-half of the elastic connector. When the auxiliary lamp approaches the main lamp, the rigid connector is completely in the first groove, and the elastic connector is also completely placed in the second groove, the auxiliary lamp forms a circle, and the outer wall of the main lamp is completely fitted with the auxiliary lamp. The rigid connector is provided with a convex strip. In order to support the weight of the auxiliary lamp itself, the main lamp and the auxiliary lamp are connected by a rigid connector, and the rigid connector can be retracted to achieve the change of the position and angle of the auxiliary lamp. The convex strip of the rigid connector is designed to achieve stable retraction of the connector, which is achieved in the following way: an elastic protrusion is provided at the end of the first groove, and the curvature radius of the protrusion is the same as that of the elastic protrusion at the end of the first groove, and the elastic protrusion can play a role of limiting. In order to increase the stability of the device, the auxiliary lamps are connected by an elastic connector. Due to the limitation of geometric constraints, the auxiliary lamps are elastically connected.

[0009] The beneficial effects of the present invention are as follows: the main lamp has the function of focusing light, the auxiliary lamp outside the main lamp can play the role of supplementary light, and the focusing height of the main lamp and the position of the auxiliary lamp can be intelligently remotely controlled according to actual needs. The present invention is easy to operate, has the functions of both a diagnosis and treatment lighting lamp and a shadowless lamp, and has a sufficiently high brightness at the focus center without generating shadows.
