[0001] The utility model relates to electronic circuit technical field, especially a kind of circuit based on color identification nail bin assembly. BACKGROUND

[0002] In modern surgery, as an indispensable medical instrument, stapler is widely used in various surgical operations, and its nail bin assembly usually has different sizes to adapt to different surgical needs. However, the end of the stapler nail bin assembly widely used in the market is mostly the same color, which brings many inconveniences to medical staff in identification. During the operation, doctors usually need to rely on naked eyes to judge the size and type of nail bin assembly, which not only increases the workload of doctors, but also is easily affected by human factors, leading to inaccurate judgment, low efficiency, and even may cause medical accidents.

[0003] At present, most domestic and foreign medical instrument manufacturers let the operator himself to judge and identify the stapler nail bin assembly, Figure 1 The nail bin assembly 1 in the needs to let the operator himself to judge and identify whether it matches the instrument rod, if it matches, then insert it into the instrument rod 2, the operator usually needs to spend a lot of time and energy to distinguish and identify different types of components, which not only increases the workload, but also may lead to identification error, and further affect the operation efficiency and quality.

[0004] As Figure 2 shown in the prior art is a kind of stapler nail bin assembly card recognition mode. This identification system consists of several key parts, including nail bin identification chip 3, nail bin identification area 4, nail bin assembly 5 and stapler rod 6.

[0036] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0037] Figure 3 is a matching schematic view of the staple cartridge assembly and the instrument rod according to an embodiment of the present application;

[0038] As shown in FIG. 4, the color recognition circuit according to an embodiment of the present application includes a light source driving module 9, a color sensor module 10, and a signal processing module 11. The light source driving module 9 and the color sensor module 10 are respectively connected to the signal processing module 11.

[0039] Here, the signal processing module 11 is a microprocessor MCU.

[0040] Specifically, the light source driving module 9 includes an LED 91 and a resistor 92, the positive terminal of the LED 91 is connected with the power supply VCC, the negative terminal of the LED 91 is connected with the I / O terminal of the signal processing module 11, and the length of the light source is controlled by program control MCU I / O pin pull-up or pull-down writing corresponding value to the register of the MCU.

[0041] Here, the LED 91 selects a white light source.

[0042] The color recognition circuit designed by the utility model selects a white light source, which is considered for the following reasons,

[0043] In color recognition, a standard light source needs to be selected to illuminate the object to be identified. White light, as a common light source, has high brightness and stability. In addition, white light itself is a mixed light source, and white light is composed of multiple colors of light. Therefore, it can provide more comprehensive spectral information. This makes white light in color recognition can cover a wider color gamut, so as to more accurately identify the color of the object. Moreover, the white light source usually has high cost performance, which can reduce the system cost while ensuring the color recognition effect.

[0044] In the color recognition circuit of the utility model, the appropriate resistance value is selected according to the need to adjust the brightness of the white light source.

[0045] Specifically, by adjusting the brightness of the white light source, it can ensure that the color of the object surface is accurately reflected on the sensor. Appropriate brightness can ensure that the sensor can capture enough light signals, so as to accurately identify the color of the object. In addition, different objects and scenes may require different brightness to ensure the accuracy of color recognition. For example, for high-reflectivity objects, too strong light source may cause color distortion or reflection, and too weak light source may not be able to provide enough light signals for color recognition. By adjusting the brightness of the white light source, the sensor can obtain the best color recognition effect in different scenes and objects.

[0046] Here, in order to accurately identify the nail cartridge assembly 7, the brightness of the light source can be adjusted.

[0047] The color sensor module 10 includes a capacitor C1, a first resistor 13, a second resistor 12 and a color sensor, the SDA pin of the MCU is connected with the color sensor, and the power supply VCC is connected through the first resistor 13, the SCL pin of the MCU is connected with the color sensor, and the power supply VCC is connected through the second resistor 12, the first output end of the color sensor is grounded, the second output end of the color sensor is connected with the power supply VCC, the third output end and the fourth output end of the color sensor are grounded, and VCC is grounded through the capacitor C1;

[0048] Here, the communication mode adopts I 2 C communication, can also be SPI, UART, CAN, RS485, RS232, USB, MODBUS and the like.

[0049] The color sensor here selects a color sensor with high precision and high stability, and an exemplary embodiment of the utility model selects a sensor based on the RGB principle, which can accurately capture the light information of the three primary colors of red, green and blue.

[0050] The nail cartridge assembly 7 comprises a color module for identifying the model specification of the tail part 7 of the nail cartridge assembly, and in an embodiment of the utility model, the color module of the tail part 7 of the nail cartridge assembly is encoded with different colors, representing different nail cartridge length, nail height and other information, and different colors such as red, blue and yellow are used to identify the model specification information; it should be noted that the color coding is clear, easy to identify, and not easy to fade.

[0051] The color sensor is internally provided with independent photosensitive elements that can separate colors according to the wavelength of light waves, so that the reflected color light is received by the corresponding photosensitive element, thereby collecting different anastomat assembly colors.

[0052] Specifically, when the anastomat nail cartridge assembly 7 is connected with the anastomat rod 8, the white light source LED of the anastomat rod 8 irradiates the color module on the tail part 7 of the anastomat assembly, and the color module reflects a specific wavelength of light wave according to its own color characteristics, the color reflected light wave is sent to the color sensor module 10, and then the color sensor module 10 converts the reflected color light wave into an electrical signal and feeds back to the MCU, the MCU processes through the internal color algorithm program, finds the color and model in the contrast library, and judges which model the color corresponds to, if the model corresponds to the instrument rod, the installation is successful, if not, the installation is unsuccessful. Thus, the corresponding anastomat nail cartridge assembly is automatically identified by color.

[0053] Specifically, the MCU receives the information of the color sensor, executes the color recognition algorithm, and compares with the preset color threshold value. The MCU can automatically identify the model specification parameters of the anastomat assembly, such as nail cartridge length, nail height, etc.

[0055] The utility model discloses an embodiment of the utility model also discloses the identification method of color recognition circuit as above, as shown in Figure 6 It is the color recognition flow chart of an embodiment of the utility model, and specifically includes:
