Description

Technical Field

[0001] The present invention relates to the technical field of electronic circuits, and in particular to a circuit for identifying a nail magazine assembly based on color and an identification method thereof. Background Art

[0002] In modern surgery, staplers are an indispensable medical device that is widely used in various surgical operations. Their stapler components usually have different sizes to meet different surgical needs. However, most of the stapler components widely used on the market have the same color at the ends, which brings a lot of inconvenience to medical staff when identifying them. During surgery, doctors usually need to rely on their naked eyes to judge the size and type of stapler components, which not only increases the workload of doctors, but is also easily affected by human factors, resulting in inaccurate judgments, low efficiency, and even medical accidents.

[0003] At present, most domestic and foreign medical device manufacturers allow operators to identify the stapler cartridge components by themselves. Figure 1 The nail magazine assembly 1 needs to let the operator judge and identify whether it matches the instrument rod. If it matches and is inserted 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 recognition errors, thereby affecting the efficiency and quality of the operation.

[0004] like Figure 2 The figure shows a card swiping identification method of a stapler cartridge assembly in the prior art. This identification system is composed of several key parts, including a cartridge identification chip 3, a cartridge identification area 4, a cartridge assembly 5, and a stapler rod 6. However, this identification method is quite cumbersome and complicated in actual operation, and has low efficiency.

[0005] Specifically, the operator first needs to accurately insert the stapler assembly 5 into the stapler rod 6 to ensure that the connection between them is stable and reliable. Then, in order to identify the assembly, the operator needs to remove the stapler identification chip 3 from the installed stapler assembly. This step requires meticulousness and caution to avoid damaging the chip or affecting the accuracy of identification.

[0006] After removing the cartridge identification chip 3, the operator needs to bring it to the cartridge identification area 4 for identification. This area is usually located next to or near the surgical instrument. The operator needs to align the chip in his hand with the identification area and wait for the system to read the information in the chip. If the identification is successful, the system will display relevant information about the cartridge assembly for the operator's reference.

[0007] However, this process is quite cumbersome and complicated in actual operation. First, the operator needs to frequently move between the instrument and the identification area, which not only increases the complexity of the operation, but also may cause contamination or damage to the surgical instrument due to improper movement. Secondly, the operation of removing and placing the identification chip also takes a certain amount of time and energy, which further reduces the efficiency of the operation. Therefore, the application of this card swiping identification method of the stapler cartridge assembly in surgery has obvious limitations and shortcomings.

[0008] In summary, how to solve the technical problem of being able to automatically and accurately identify the stapler cartridge assembly in the prior art is a technical problem that urgently needs to be solved. Summary of the invention

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Figure 3 This is a schematic diagram of the matching of the stapler staple magazine assembly and the instrument rod. The tail of the stapler staple magazine assembly 7 uses different colors to represent different models and specifications of the stapler staple magazine assembly. The color recognition circuit provided in one embodiment of the present invention is designed in the stapler rod 8. When the stapler staple magazine assembly 7 is connected to the stapler rod 8, the color recognition circuit in the stapler rod 8 can automatically identify the model of the stapler staple magazine assembly through the color module at the tail of the stapler staple magazine assembly 7, thereby enabling the stapler rod 8 to complete different operations.

[0040] As shown in FIG4 , a color recognition circuit is provided in one embodiment of the present invention. The color recognition circuit 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.

[0041] Here, the signal processing module 11 is a microprocessor MCU.

[0042] Specifically, the light source driving module 9 includes an LED 91 and a resistor 92, the positive terminal of LDE 91 is connected to the power supply VCC, and the negative terminal of LDE 91 is connected to the I / O terminal of the signal processing module 11. The I / O pin of the MCU is pulled high or low by the program to write the corresponding value to the register of the MCU to control the length of time the light source is on.

[0043] Here, LED91 selects a white light source.

[0044] The color recognition circuit designed by the present invention selects a white light source for the following reasons:

[0045] In color recognition, a standard light source needs to be selected to illuminate the object to be recognized. White light, as a common light source, has high brightness and stability. In addition, the spectral characteristics of white light itself are mixed light sources. White light is a mixture of multiple colors of light, so it can provide more comprehensive spectral information. This allows white light to cover a wider color gamut in color recognition, thereby more accurately identifying the color of the object. In addition, white light sources usually have a high cost-effectiveness, which can reduce system costs while ensuring color recognition effects.

[0046] In the color recognition circuit of the present invention, the brightness of the white light source is adjusted by selecting a suitable resistor value according to the needs.

[0047] Specifically, by adjusting the brightness of the white light source, it is possible to ensure that the color of the object's surface is accurately reflected on the sensor. Appropriate brightness ensures that the sensor can capture enough light signals 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 objects with high reflectivity, a light source that is too strong may cause color distortion or reflection, while a light source that is too weak may not provide enough light signals for color recognition. By adjusting the brightness of the white light source, it is possible to ensure that the sensor can achieve the best color recognition effect in different scenes and objects.

[0048] Here, in order to accurately identify the nail magazine assembly 7, the brightness of the light source can be adjusted.

[0049] The color sensor module 10 includes a capacitor C1, a first resistor 13, a second resistor 12 and a color sensor, wherein the SDA pin of the MCU is connected to the color sensor and connected to the power supply VCC through the first resistor 13, the SCL pin of the MCU is connected to the color sensor and connected to the power supply VCC through the second resistor 12, the first output terminal of the color sensor is grounded, the second output terminal of the color sensor is connected to the power supply VCC, the third output terminal and the fourth output terminal of the color sensor are grounded, and VCC is grounded through the capacitor C1;

[0050] Here, the communication method adopts I 2 C communication, or SPI, UART, CAN, RS485, RS232, USB, MODBUS and other modes.

[0051] The color sensor here is a high-precision, high-stability color sensor. For example, the embodiment of the present invention 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;

[0052] The nail magazine assembly 7 includes a color module for identifying the model specifications of the nail magazine assembly tail 7. In one embodiment of the present invention, the color module of the nail magazine assembly tail 7 is coded with different colors to represent different nail magazine lengths, nail heights and other information. Different colors such as red, blue and yellow are used for identification according to different model specification information. It should be noted that the color coding is clear, easy to identify, and not easy to fade.

[0053] The color sensor is internally provided with an independent photosensitive element that can separate colors according to the wavelength of the light wave, so that the light of the reflected color is received by the corresponding photosensitive element respectively, thereby collecting the colors of different stapler components.

[0054] Specifically, after the stapler cartridge assembly 7 is connected to the stapler rod 8, the white light source LED of the stapler rod 8 irradiates the color module on the stapler assembly tail 7, and the color module reflects a light wave of a specific wavelength 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 it back to the MCU. The MCU processes it through the internal color algorithm program, searches the color and model in the reference library, and determines which model the color corresponds to. If the model corresponds to the instrument rod, the installation is successful, and if not, the installation is unsuccessful. Thus, the corresponding stapler cartridge assembly can be automatically identified by color.

[0055] Specifically, the MCU receives information from the color sensor, executes a color recognition algorithm, and compares it with a preset color threshold. The MCU can automatically identify the model and specification parameters of the stapler assembly, such as the stapler length, staple height, etc., based on the recognition results.

[0056] Figure 5 A power module is used in an embodiment of the present invention. The power module includes a low voltage dropout linear regulator U1, a capacitor C2, and a capacitor C3. The VIN terminal of the low voltage dropout linear regulator U1 is grounded through the capacitor C3, and the VOUT terminal of the low voltage dropout linear regulator U1 is grounded through the capacitor C2. The power module uses a low voltage dropout linear regulator to achieve efficient linear voltage adjustment. VIN is a power supply input, and a stable power supply VCC is output through the low voltage dropout linear regulator to provide a stable power supply for the entire circuit.

[0057] An embodiment of the present invention further discloses a recognition method of the above color recognition circuit, such as Figure 6 The figure is a schematic diagram of a color recognition process according to an embodiment of the present invention, which specifically includes:

[0058] The stapler assembly tail 7 is inserted into the stapler rod 8, and the microprocessor MCU identifies whether the stapler assembly tail 7 has been inserted. If it is determined that it has been inserted, the microprocessor reads color data from the color sensor, and the color data is the light wave data of the stapler assembly tail 7 sending the reflected light wave to the color sensor; a mapping table is provided inside the microprocessor, and the mapping table is a correspondence table between the reflected light wave data and the stapler assembly model and specification information. Here, the stapler assembly model and specification information includes the stapler magazine information. The mapping table is searched to see whether there is read-in color data in the preset color data. If so, the stapler magazine information is taken out from the lookup table according to the color data, and the operator is prompted to perform subsequent operations; if not, continue to wait for the insertion of the component of the correct color.

[0059] After adopting such a design, the present invention has at least the following advantages:

[0060] (1) The circuit design of the present invention can realize rapid and accurate identification of the stapler cartridge assembly, reduce the influence of human factors, and improve the safety and efficiency of surgery.

[0061] (2) The circuit design of the present invention can not only reduce the workload of doctors, but also effectively shorten the operation time, reduce the risk of medical accidents, and protect the health of patients.

[0062] (3) The circuit designed by the present invention is integrated into the appropriate position of the stapler rod, which can quickly and directly capture and identify the color information of the stapler assembly.
