Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of rotary head position recognition, and in particular to a rotary head position recognition device and a recognition method thereof. Background Art
[0002] An electric stapler is an advanced medical device widely used in modern surgical operations. It is mainly used for the rapid and precise anastomosis of hollow organs such as the digestive tract and respiratory tract. The electric stapler is driven by a motor to complete the stapling and cutting actions. It is worth noting that the rotating head, as the core functional module of the electric stapler, has the characteristics of multi-angle adjustment, and the correct choice of its rotation direction is not only a key link for the smooth operation, but also the top priority for avoiding poor anastomosis.
[0003] However, during the use of the electric stapler, it is sometimes necessary to manually adjust the direction of the rotating head to achieve clamping in different directions. During this process, the control panel cannot know the direction of the rotating head. Therefore, when the same head swing button is pressed, the head sometimes swings to the left and sometimes swings to the right. Therefore, the operator needs to distract himself to remember the direction of the rotating head to achieve operation in the expected head swing direction.
[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Summary of the Invention

[0009] Furthermore, in order to realize the recognition of the rotation direction, the real-time perception of the current direction of the rotating head can be realized under the action of the outer ring copper skin. The slip ring mover assembly includes an inner ring copper skin connected to the slip ring stator assembly, one side of the inner ring copper skin is connected to the rotor, one side of the rotor and located on the outside of the inner ring copper skin is connected to the middle ring copper skin, and the top outside of the middle ring copper skin is connected to the outer ring copper skin; the inner ring copper skin and the middle ring copper skin are circular structures, and the connection between the outer side of the middle ring copper skin and the inner side of the outer ring copper skin is an electrical short circuit connection; the outer ring copper skin is a semicircular arc structure with an opening downward.

[0016] According to an embodiment of the present invention, a rotating head position recognition device is provided.
[0017] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

A second middle ring elastic pin 3014 is symmetrically connected to one side of the first inner ring elastic pin 3011 and located at the other end thereof; a first outer ring elastic pin 3015 connected to the first resistor 2 is connected to one side of the fixed plate 3017 and located at the top of the second middle ring elastic pin 3014; a second outer ring elastic pin 3016 connected to the second resistor 4 is connected to one side of the fixed plate 3017 and located at the bottom of the first middle ring elastic pin 3013; the first inner ring elastic pin 3011 is rotated 180 degrees along the center point of the fixed plate 3017 to coincide with the second inner ring elastic pin 3012 The first inner ring elastic pin 3011 and the second inner ring elastic pin 3012 are both connected to the inner ring copper sheet 3021; the first middle ring elastic pin 3013 is rotated 180 degrees along the center point of the fixed plate 3017 and coincides with the second middle ring elastic pin 3014; the first middle ring elastic pin 3013 and the second middle ring elastic pin 3014 are both connected to the middle ring copper sheet 3022; the first outer ring elastic pin 3015 is rotated 180 degrees along the center point of the fixed plate 3017 and coincides with the second outer ring elastic pin 3016; the first outer ring elastic pin 3015 is connected to the outer ring copper sheet 3023 Connect; the distance from the position of the first inner ring spring pin 3011 to the center point of the fixed plate 3017 is smaller than the distance from the position of the first middle ring spring pin 3013 to the center point of the fixed plate 3017; the distance from the position of the first middle ring spring pin 3013 to the center point of the fixed plate 3017 is smaller than the distance from the position of the first outer ring spring pin 3015 to the center point of the fixed plate 3017; under the action of the inner ring, middle ring and outer ring spring pins, the slip ring stator assembly 301 can cooperate with the slip ring mover assembly 302 to identify the rotation signal and the verification signal.
[0020] In one embodiment, for the above-mentioned slip ring mover assembly 302, the slip ring mover assembly 302 includes an inner ring copper skin 3021 connected to the slip ring stator assembly 301, one side of the inner ring copper skin 3021 is connected to the rotor 3024, one side of the rotor 3024 and located on the outside of the inner ring copper skin 3021 is connected to the middle ring copper skin 3022, and the top outside of the middle ring copper skin 3022 is connected to the outer ring copper skin 3023; the inner ring copper skin 3021 and the middle ring copper skin 3022 are circular ring structures, and the connection between the outer side of the middle ring copper skin 3022 and the inner side of the outer ring copper skin 3023 is an electrical short circuit connection; the outer ring copper skin 3023 is a semicircular arc structure with an opening facing downward; under the action of the outer ring copper skin 3023, real-time perception of the current direction of the rotating head can be achieved.
[0021] like Figure 5 According to another embodiment of the present invention, a method for identifying the position of a rotating head is provided, the method comprising the following steps: S1, obtaining the rotation signal and verification signal output by the semi-energized conductive slip ring 3, and judging the rotation signal and verification signal through the microprocessor 5; S2. Determine the current angle and direction of the rotating head according to the judgment result, adjust the swing direction of the head controlled by the key using the current angle and direction of the rotating head, and control the motor drive based on the adjusted swing direction of the head.
[0022] Specifically, the electric stapler automatically identifies the direction of the rotating head through a semi-energized conductive slip ring 3. Signals are transmitted through the semi-energized conductive slip ring 3, and detected by the microprocessor 5. A 180-degree rotation of the rotating head generates an output voltage change. The microprocessor 5 identifies this voltage change and determines the current angle and direction of the rotating head. This allows the microprocessor 5 to adjust the direction of the head controlled by the button, ensuring that the direction of the head controlled by the same button remains visually consistent regardless of the direction of the rotating head.
[0023] It should be noted that the semi-energized conductive slip ring 3 is divided into a slip ring rotor assembly 302 and a slip ring stator assembly 301. The slip ring rotor assembly 302 comprises an inner copper ring 3021, a middle copper ring 3022, and an outer copper ring 3023. The inner copper ring 3021 is a complete copper ring, the middle copper ring 3022 is a complete circle of copper ring, and the outer copper ring 3023 is a partial area extending outward from the outer side of the middle copper ring 3022. The middle copper ring 3022 and the outer copper ring 3023 are electrically short-circuited. The slip ring stator assembly 301 comprises two first inner ring spring pins 3011, two second inner ring spring pins 3012, two first middle ring spring pins 3013, two second middle ring spring pins 3014, a first outer ring spring pin 3015, and a second outer ring spring pin 3016. Of these three spring pins, the inner and middle ring spring pins each have four spring contacts. The outer ring spring pin has two spring contacts.
[0024] It should be noted that in actual use of the rotary head position identification device, the inner copper ring 3021 of the slip ring rotor assembly 302 is connected to the assembly chip communication signal, the middle copper ring 3022 is connected to the assembly chip GND signal, and the outer copper ring 3023, due to being electrically shorted to the middle copper ring 3022, also serves as the GND signal. The first inner ring spring pin 3011 and the second inner ring spring pin 3012 of the slip ring stator assembly 301 are connected to the microcontroller communication pin, the first middle ring spring pin 3013 and the second middle ring spring pin 3014 are connected to the power supply GND, and the spring contact of the first outer ring spring pin 3015 and the spring contact of the second outer ring spring pin 3016 are connected to the microcontroller IO port and are connected to the positive power supply assembly 1 through a first resistor 2 and a second resistor 4, respectively. That is, the positive power supply assembly 1 includes two VCCs. Among them, the other end of the first resistor 2 is connected to one end of one of the VCCs; one end of the second resistor 4 is connected to one end of the other VCC, one end of the first resistor 2 is connected to the second pin of the semi-energized conductive slip ring 3, that is, one end of the first resistor 2 is connected to the first outer ring spring pin 3015, the other end of the second resistor 4 is connected to the third pin of the semi-energized conductive slip ring 3, that is, the other end of the second resistor 4 is connected to the second outer ring spring pin 3016, the first pin of the semi-energized conductive slip ring 3 is connected to GND, that is, the first middle ring spring pin 3013 and the second middle ring spring pin 3014 are connected to GND, one end of the first resistor 2 is connected to one end of the microprocessor 5 and the second pin of the semi-energized conductive slip ring 3, and the other end of the second resistor 4 is connected to the other end of the microprocessor 5 and the third pin of the semi-energized conductive slip ring 3.
[0025] It should be noted that in actual use of the rotating head position identification device, the first middle ring spring pin 3013 and the second middle ring spring pin 3014 of the slip ring stator assembly 301 transmit the GND signal to the middle ring copper sheet 3022 and the outer ring copper sheet 3023 of the slip ring mover assembly 302. When the spring contacts of the first outer ring spring pin 3015 and the second outer ring spring pin 3016 contact the outer ring copper sheet 3023, two situations may occur. The first situation is that when they contact the outer ring copper sheet 3023, a GND signal is output. The second situation is that when they contact an area without copper sheet, a VCC signal is output due to the presence of the first pull-up resistor 2 and the second pull-up resistor 4. The spring contact of the first outer ring spring pin 3015 is used to identify the direction, and the spring contact of the second outer ring spring pin 3016 is used to verify whether the voltage level of the spring contact of the first outer ring spring pin 3015 is correct. When the spring contact of the first outer ring spring pin 3015 contacts the outer ring copper sheet 3023 to output a GND signal, the spring contact of the second outer ring spring pin 3016 must contact the area without copper sheet to output a VCC signal. Conversely, when the spring contact of the first outer ring spring pin 3015 contacts the area without copper sheet to output a VCC signal, the spring contact of the second outer ring spring pin 3016 must contact the outer ring copper sheet 3023 to output a GND signal. This prevents the spring contact signal of the first outer ring spring pin 3015 from failing and causing recognition errors.
[0026] It should be noted that if Figure 5 As shown, the rotation signal and the verification signal are judged by the microprocessor 5. When the rotation signal is one and the verification signal is zero, the motor is controlled to rotate forward; when the rotation signal is zero and the verification signal is one, the motor is controlled to rotate reversely.
[0027] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation mode of the present invention in actual process is described in detail below.
[0028] In actual application, when the left swing button is pressed, when the spring contact of the first outer ring spring pin 3015 of the slip ring stator assembly 301 contacts the outer ring copper sheet 3023 of the slip ring rotor assembly 302, the spring contact output signal of the first outer ring spring pin 3015 of the slip ring stator assembly 301 is a GND signal. After the microprocessor 5 recognizes it, it controls the motor to rotate in the normal direction, which visually appears to be a left swing. When the spring contact of the first outer ring spring pin 3015 of the slip ring stator assembly 301 contacts the copper-free portion of the outer ring copper sheet 3023 of the slip ring rotor assembly 302, the microprocessor 5 recognizes a high-level signal. The microprocessor 5 controls the motor to rotate in the reverse direction, so that it still visually appears to be a left swing. When the right swing button is pressed, the principle is the same as that of pressing the left swing button, and the motor rotates in the opposite direction. At the same time, the spring contact of the second outer ring spring pin 3016 of the slip ring stator assembly 301 outputs a reverse signal to prevent the spring contact of the first outer ring spring pin 3015 of the slip ring stator assembly 301 from outputting a signal failure that causes recognition error.
[0029] In summary, with the aid of the above technical solution of the present invention, the present invention introduces a rotation direction feedback and intelligent control mechanism through the coordinated arrangement of the positive power supply component 1, the first resistor 2, the second resistor 4, the semi-energized conductive slip ring 3 and the microprocessor 5, thereby realizing the real-time perception of the current orientation of the rotating head and the logical unification of the key-pressed head swing direction; so that no matter what angle and direction the rotating head is in, the operator only needs to press the designated "swing head" key to complete the precise swing in the expected direction, without the need to additionally remember the current angle and direction of the rotating head, and without the need for additional switches, dedicated circuits, and sensors. The desired effect can be achieved through the semi-energized conductive slip ring 3, and a verification signal can be output to prevent recognition errors, which is more convenient and safe, thereby greatly reducing the complexity of operation, improving the convenience and safety during the operation, effectively avoiding the risk of repeated operation or poor matching due to misjudgment of direction, and further ensuring the quality and safety of operation.
