Description

Cross-reference This disclosure relates to Chinese Patent Application No. 202310749306.6, filed on 21 June 2023 and titled “ILLUMINATION APPARATUS FOR MEDICAL INSTRUMENT AND MEDICAL INSTRUMENT KIT,” which is incorporated herein by reference in its entirety. This disclosure relates to the technology of medical devices, and more particularly to lighting devices and medical device kits for medical devices. Currently, surgical illumination relies primarily on shadowless lamps, which are generally effective in most applications. However, in some procedures, light cannot reach deep wounds, making illumination difficult. This is particularly pronounced in situations involving deep, narrow wounds with significant internal cavities, making the use of shadowless lamps impractical. This disclosure is intended to solve at least one of the technical problems present in the background technology. According to one aspect of this disclosure, several embodiments of this disclosure provide a lighting device for a medical device, the lighting device comprising a housing component having a housing space extending along the longitudinal axis of the housing component, and a lighting assembly disposed within the housing space and having a channel extending along the longitudinal axis. By applying lighting devices according to some embodiments of this disclosure to medical devices, such as by fixing the lighting device to the medical device, it is possible to provide direct illumination to the operating position during the operation of the medical device, thereby facilitating clear visibility of the operating position by the operator of the medical device. It should be understood that the term "medical device" in this disclosure may include any type of medical device, such as surgical scalpels, surgical clamps, surgical forceps, and irrigation or suction tubes. Surgical scalpels may include ultrasonic scalpels and electrosurgical scalpels. In some embodiments of this disclosure, the lighting assembly may include a light-emitting element and a light guide element positioned adjacent to the light-emitting element and configured to guide the light emitted from the light-emitting element to the outside of the lighting device, wherein the light-emitting element and the light guide element jointly define a channel. In the embodiments described above, the light-emitting element may be positioned in contact with the light-guiding element, or it may be positioned at a certain distance from the light-guiding element, as long as the light-guiding element can guide the light emitted from the light-emitting element to the outside of the lighting device. In some embodiments of this disclosure, the light-emitting element may be annular, and the light guide element may also be cylindrical; therefore, the light-emitting element and the light guide element can jointly define a channel having a circular cross-section. In some embodiments of this disclosure, the light-emitting element includes one or more combinations of a halogen lamp, an LED emitter, or an optical fiber. In some embodiments of this disclosure, the light guide element is transparent or translucent. In some embodiments of this disclosure, the light guide element is made of one or more materials selected from polycarbonate, polyethylene terephthalate, polypropylene, and polymethyl methacrylate. In some embodiments of this disclosure, the light guide element further includes a light diffusing agent. The light diffusing agent may include inorganic light diffusing agents (e.g., nanobarium sulfate, calcium carbonate, silicon dioxide, etc.) and organic light diffusing agents (e.g., acrylic-based, styrene-based, acrylic resin-based, etc.). Adding a light diffusing agent to the light guide element can expand the illumination range and/or illumination uniformity of the lighting device. In some embodiments of this disclosure, the light guide element extends a predetermined distance from the housing space. Since the external dimensions of the light guide element are smaller than those of the housing component, the light guide element can be positioned to extend a predetermined distance from within the housing space, thereby bringing it closer to the operating position of the medical device. Furthermore, the light guide element avoids obstructing the view of the medical device operator when the housing component, which has larger external dimensions, approaches the operating position of the medical device. In some embodiments of this disclosure, the lighting device further includes a power supply electrically connected to the lighting assembly. It should be noted that the term "power supply" as used herein may refer to a power supply fixedly connected to the lighting assembly, or a power supply detachably connected to the lighting assembly (for example, the power supply is an external power supply electrically connected to the lighting assembly by wires). In some embodiments of this disclosure,
