In addition to the light source assembly 102, the detachable light source component 10 can also include a tube assembly 104. The tube assembly 104 can include a flexible tube 1040 having a first end 1040a and a second end 1040b relative to 1040a. The flexible tube 1040 can be made of polyurethane, tantalum, fluoropolymer, glass, quartz glass, polycarbonate, polyoxyxene elastomer, polyethylene and polymethyl methacrylate, or any other material suitable for medical use. . A spiral tube 1042 can be inserted into and surrounded by the flexible tube 1040, which can be of any electrically conductive material, such as metal, to facilitate power supply to the light source assembly 102. A connector collar 1044 can be adjacent to the first end 1040a and surround a portion of the flexible tube 1040. A wire or contact (not shown) for powering the battery to the light source assembly 102 can be covered by the connector collar 1044. An insert connector 1046 can be attached to the first end 1040a and connected to a wire or joint. The tube assembly 104 can also include a light source collar 1048 mounted on the second end 1040b and surrounding the light source assembly 102.

The light source assembly 102 can include a light source 1020 for illumination. The light source 1020 can be a light-emitting diode because of its small size, high brightness, high power and high efficiency. High-power white LEDs are commonly used for illumination, such as illumination and recognition of tumor perimeters, and any residual tumors that are extremely difficult to detect after removal of necrotic tissue and solid tumors. The light source 1020 is replaceable, for example, by a blue LED, a green LED, or a red LED. Since red, green, and blue light have different wavelengths, it is possible to recognize different uses in different regions and at different points. For example, cancer and microvasculature are more likely to be localized by blue light, so blue LEDs can be used to identify and locate small tumors during surgical procedures. Because the red wavelength is the longest, red LEDs can be used to identify blood vessels in deep areas. The light source 1020 can also be replaced by ultraviolet and infrared wavelengths depending on its application. In another aspect, the light source 1020 can emit wavelengths of multiple spectra, such as a multi-color LED or include more than one LED.

The light source assembly 102 can include an optical element 1022 that covers the light source 1020. The optical element 1022 can be or include a diffuser that diffuses, disperses or scatters light in some manner to control light distribution. High power LEDs or high output LEDs can be driven at high currents. Because overheating is destructive, a heat dissipating component 1024 can be used to dissipate heat. The optical element 1022 can also be or include a lens for directing or focusing light. The heat dissipating component 1024 can be made of electrical and thermal conductive materials such as silver, aluminum, gold, copper, iron, molybdenum, lead, platinum or any other suitable material having electrical and thermal conductivity. The light source assembly 102 can include a base 1026 for receiving the heat dissipation unit 1024. A convex portion 1028 can be formed on the bottom surface of the base 1026. The convex portion 1028 is inserted into the spiral tube 1042 such that the base 1026 is seated at one end of the spiral tube 1042. The substrate 1026 can be made of a thermally conductive material, such as stainless steel, to help dissipate the heat generated by the source 1020.

After the light source component 10 is assembled, the spiral tube 1042 is enclosed within the flexible tube 1040 and surrounded by the flexible tube 1040. The light source assembly 102 is at the second end 1040b of the flexible tube 1040. The light source collar 1048 surrounds the light source assembly 102. The connector collar 1044 surrounds a portion of the flexible tube 1040 at its first end 1040A.

The first outer casing portion 202 and the second outer casing portion 204 can be made of any material suitable for medical use. to make. In the injection molding process, a specific structure of the outer surface or interior of the outer casing can be fabricated. For example, a handle structure 206 can be formed on the outer surface of the outer casing 20 to allow the user to handle or use the lighting device. As another example, an opening 208 can be made in the portion of the outer casing 20 where the button extends. When the first housing portion 202 and the second housing portion 204 operate together, a space can be created in the housing 20.

A power supply assembly 30 can be placed in an empty space formed by the two outer casing portions 202 and 204 between. The power supply assembly 30 can include a circuit board 302 with circuit printing. The circuit board 302 can include various components such as one or more processors, memory communication components, and/or input/output components. The power module 30 can include a battery 304, such as a rechargeable lithium ion battery, coupled to the circuit board 302 to provide power to the light source assembly 102 for illumination. The switch 306 can be coupled to the circuit board 302 and operate in a conductive state, such as "on", and a non-conducting state, such as "off." The button 210 operation can instruct the operator to turn the lighting device on or off. The switch 306 can be physically coupled to the button 210 and receive an indication as an input signal. The input signal can be sent to the processor. The processor can provide power to the output component or disconnect the power source upon receiving the input signal. The processor allows the output component to provide pulsed current, such as a square current and a duty cycle that adjusts the pulse current. By adjusting the frequency of the pulse current, the source 1020 can operate in a discontinuous state to reduce the amount of heat generated by the current. The power module 30 can also include wireless functionality. For example, the circuit board 302 includes a wireless component 308, for example, including a wireless transmitter and a wireless receiver or a wireless transceiver to allow wireless operation and control of the lighting device. For example, a wireless function can be used to control the on/off function of the lighting device, thereby avoiding the need to provide the opening 208, the switch 306, and the button 210. Likewise, for example, wireless functionality can be used to control the operation of the light source assembly 102, such as to select the color, power, frequency, pulse, duty cycle, and/or other operations of the light source.

A connector assembly 40 can be electrically connected as an electronic interface to the light source component 10. The power component 30 can provide power from the rechargeable battery 304 to the light source component 10 via the electronic interface. The connector assembly 40 can include a contact 402 to connect the circuitry of the circuit board 302. A receiving connector 404 coupled to the contact 402 can be a male connector. The receiving connector 404 disposed within the housing 20 allows the socket 4040 to accept the conduit of the connector 1046.

In operation, when the button 210 is depressed, the switch 306 can receive an input signal indicating that the lighting device 100 is turned on. The input signal can be sent to the processor, and the rechargeable battery 304 is powered to the light source 1020 via the connector assembly 40. In addition to the control of the connection or disconnection of the power supply, the processor determines the frequency and duty cycle of the output current. The light source 1020 can be turned on when the power supply is powered, and can be turned off when the power supply is disconnected.
