Description

Technical Field

[0001] The utility model relates to a nail box identification device for an electric stapler. Background Art

[0002] At present, the electric stapler consists of a stapler magazine, a gun rod and a handle. The closing, cutting and retracting functions of the stapler magazine are realized by the motor and related control circuits. The stapler magazine generally has different length specifications such as 30mm, 45mm or 60mm. When in use, the doctor selects staplers of different specifications and installs them on the gun rod according to the surgical requirements. The stapler magazine can be bent, and the rigidity at the bend is weak. When the cutting movement reaches the limit position and continues to move forward, the stapler magazine will produce a sudden swing movement, pulling the tissue and blood vessels, which is not allowed during the operation. Therefore, before the operation, it is necessary to identify the length specifications of the stapler magazine and select a stapler magazine that meets the surgical requirements and install it on the handle.

[0003] For example, the patent "Electric stapler with nail magazine identification system and nail magazine identification method" with application number 202111141179.9 sets multiple mounting holes on the nail magazine, and installs magnets in the mounting holes at different positions to distinguish the model of the nail magazine. An identification module is installed in the gun barrel, and the Hall sensor in the identification module senses the location of the magnet and outputs a voltage signal; a signal processing module is installed in the handle, and the voltage signal output by the Hall sensor is received and processed by the signal processing module to identify the model of the current nail magazine. However, this solution requires the installation of multiple magnets and Hall sensors to separately identify nail magazines of different length specifications, and its structure is complex and the manufacturing cost is high. Summary of the invention

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an electric stapler stapler magazine identification device, which only requires a magnet and a Hall sensor to automatically identify the length specification of the stapler magazine, has a simple and practical structure, and has a lower manufacturing cost.

[0005] In order to solve the above technical problems, the technical solution of the utility model is:

[0006] An electric stapler stapler cartridge identification device comprises a magnet, an MCU module, and an adaptive acquisition module and a display screen connected to the MCU module;

[0007] The magnet moves along with the firing push block of the electric stapler;

[0008] The adaptive acquisition module is used to collect the magnetic flux of the magnet at different sensing positions, and output the generated corresponding electrical signals to the MCU module;

[0009] The MCU module is used to receive and process the electrical signal output by the adaptive acquisition module, and control the display screen to display the nail magazine length specification information.

[0010] Furthermore, it also includes a buzzer module, which is connected to the MCU module.

[0011] Furthermore, it also includes an LED module, which includes a first LED light group, a second LED light group and a third LED light group, and the first LED light group, the second LED light group and the third LED light group are all connected to the MCU module.

[0012] Furthermore, the display screen is an LCD display screen.

[0013] Furthermore, the adaptive acquisition module includes a Hall sensor, a first operational amplifier module and a second operational amplifier module. The Hall sensor is used to collect the magnetic flux of the magnet. The output end of the Hall sensor is connected to the input end of the first operational amplifier module, the output end of the first operational amplifier module is connected to the input end of the second operational amplifier module, and the output end of the second operational amplifier module is connected to the MCU module.

[0014] Furthermore, it also includes a battery and a power module, wherein the battery is connected to the power module, and the power module supplies power to each module of the electric stapler stapler magazine identification device.

[0015] Furthermore, it also includes a battery power detection module, the input end of the battery power detection module is connected to the battery, the output end of the battery power detection module is connected to the MCU module, and the MCU module controls the display screen to display the real-time battery power.

[0016] The above technical solution is adopted. The utility model installs a magnet at the end of the firing push block. When the nail magazine is plugged and installed on the gun barrel, the nail magazine will push the firing push block to move, and the magnet moves with the firing push block. Since nail magazines of different lengths will cause the firing push block to move differently, the Hall sensor collects the magnetic flux of the magnet at different sensing positions, and automatically identifies nail magazines of different lengths according to the difference in magnetic flux. The utility model only needs one magnet and one Hall sensor to complete automatic identification, and there is no need to change the structure of the nail magazine. The structure is simple and practical, and the manufacturing cost is lower. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0027] like Figure 1 As shown, this embodiment provides an electric stapler stapler magazine 1 identification device, which includes a magnet 6, an MCU module, and an adaptive acquisition module connected to the MCU module, a display screen, a buzzer module, an LED module, a battery, a power module and a battery power detection module.

[0028] like Figure 7 , 8 As shown, the electric stapler nail magazine 1 identification device of this embodiment is applied to the electric stapler. The nail magazine 1 is inserted into the gun rod of the electric stapler. The nail magazine 1 will push the connecting piece 2 in the gun rod to move, and the connecting piece 2 will push the long rod sleeve 3 and the firing push block 5 to move. After nail magazines 1 of different length specifications are inserted into the gun rod, the strokes of pushing the connecting piece 2 to move are also different. The longer the length of the nail magazine 1, the longer the stroke of the connecting piece 2. After the nail magazine 1 is inserted into the gun rod, the magnet 6 moves with the firing push block 5.

[0029] like Figure 2 As shown, the MCU module of this embodiment adopts MCU chip U1, model M058LBN.

[0030] like Figure 2 As shown, the buzzer module of this embodiment is connected to the MCU module, and the 24th pin of the MCU chip U1 controls the buzzer K1 to emit corresponding prompt sounds in different states.

[0031] like Figure 2 As shown, the display screen of this embodiment is an LCD display screen, and the LCD display screen is connected to pins 37 and 38 of the MCU chip U1.

[0032] like Figure 1 As shown, the adaptive acquisition module of this embodiment is used to collect the magnetic flux of the magnet 6 at different sensing positions, and output the corresponding electrical signals generated to the MCU module. The MCU module is used to receive and process the electrical signals output by the adaptive acquisition module, and control the display screen to display the length specification information of the nail box 1. Figure 3 As shown, the adaptive acquisition module of this embodiment includes a Hall sensor, a first operational amplifier module and a second operational amplifier module. The Hall sensor is used to collect the magnetic flux of the magnet 6. The output end of the Hall sensor is connected to the input end of the first operational amplifier module, the output end of the first operational amplifier module is connected to the input end of the second operational amplifier module, and the output end of the second operational amplifier module is connected to the MCU module. The signal output by the Hall sensor U9 is amplified in two stages by the first operational amplifier chip U7 and the second operational amplifier chip U8, and then output to the 2nd pin of the MCU chip U1.

[0033] After the nail magazine 1 of different length specifications is connected to the gun rod, the movement stroke of the firing push block 5 in the handle 4 is also different. Fig. 9 As shown, position a in the figure is position 0, that is, the position of the firing push block 5 when the nail magazine 1 is not inserted into the gun rod. Position b in the figure is the final position after the firing push block 5 moves after the nail magazine 1 with a length of 30 mm is installed. Position c in the figure is the final position after the firing push block 5 moves after the nail magazine 1 with a length of 45 mm is installed. Position d in the figure is the final position after the firing push block 5 moves after the nail magazine 1 with a length of 60 mm is installed.

[0034] Since the distances between the b position, c position, and d position and the Hall sensor 7 in the adaptive acquisition module are different, the magnetic flux of the magnet 6 sensed and collected by the Hall sensor 7 is also different. For example: at the b position, the magnetic flux of the magnet 6 collected by the Hall sensor 7 is 1Wb. At the c position, the magnetic flux of the magnet 6 collected by the Hall sensor 7 is 2Wb. At the d position, the magnetic flux of the magnet 6 collected by the Hall sensor 7 is 3Wb. The adaptive acquisition module converts the collected magnetic fluxes of different sizes into electrical signals and sends them to the MCU module. After processing by the MCU module, different length specification information of the nail magazine 1 is displayed on the display screen. Before the operation, after the doctor installs the nail magazine 1, the handle can automatically identify which length specification of the nail magazine 1 is installed.

[0035] like Figure 1 As shown, the battery of this embodiment is connected to the power module, and the power module supplies power to each module of the electric stapler stapler magazine 1 identification device. Figure 5As shown, the electric stapler of this embodiment uses a battery as a power supply, and the power module uses a power conversion chip U5 and a power conversion chip U4. The power conversion chip U5 converts the 12V voltage of the battery into a 5V voltage for use by the adaptive acquisition module, the LED module, and the buzzer module. The power conversion chip U4 converts the 12V voltage of the battery into a 3.3V voltage for use by the MCU module and the display screen.

[0036] like Figure 1 As shown, the input end of the battery power detection module of this embodiment is connected to the battery, and the output end of the battery power detection module is connected to the MCU module. The MCU module controls the display screen to display the real-time battery power. Figure 2 As shown, the battery power detection module adopts a resistor voltage division method and is powered by 12V of the battery. The battery power detection module is connected to the 26th pin of the MCU chip U1.

[0037] like Figure 1 As shown, the LED module of this embodiment includes a first LED light group, a second LED light group and a third LED light group, and the first LED light group LD1, the second LED light group LD2 and the third LED light group LD3 are all connected to the MCU module. Figure 6 As shown, the LED light groups in this embodiment are all three-color LED lamp beads. When the nail box is detected to be 30mm in length, the first LED light group LD1 lights up green; when the nail box is detected to be 45mm in length, the second LED light group LD2 lights up green; when the nail box is detected to be 60mm in length, the third LED light group LD3 lights up green.

[0038] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
