Description

Technical Field

[0001] This invention belongs to the field of medical device technology, and specifically relates to an electric control device for the entry and exit of endoscopic treatment instruments through the forceps orifice. Background Technology

[0002] The primary purpose of endoscopy is to achieve accurate diagnosis, minimally invasive treatment, and disease monitoring by visually examining internal organs or cavities. It utilizes optical or electronic devices to directly observe the internal structures of the human body, helping doctors detect lesions, obtain tissue samples, and perform endoscopic surgery when necessary. Endoscopy offers advantages such as minimal trauma and rapid recovery. Endoscopes are typically used in conjunction with specialized instruments, which are inserted into the patient's body through instrument channels, such as grasping suspected lesions, removing digestive tract tumors, and closing digestive tract wounds. During clinical procedures, doctors usually operate the endoscope with one hand while supporting the insertion of the endoscope with the other, and the control of the instruments is typically assisted by an assistant. This collaborative operation reduces the efficiency of endoscopic treatment, especially when precise control of instrument insertion and removal is required. Therefore, an electronic control device needs to be designed to enable the surgeon to perform precise operation of the instruments, thus facilitating the efficient use of endoscopic instruments. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the present invention provides an electric control device for the entry and exit of endoscopic treatment instruments through the forceps orifice.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An electrically controlled device for the entry and exit of endoscopic therapeutic instruments includes a main control device and a foot pedal control device. The main control device is detachably installed in a V-shaped fork between the operating part of the endoscope and the instrument forceps channel. The main control device and the foot pedal control device are wirelessly connected. The main control device includes a triangular housing, roller mechanisms, an operation panel, a control board, and a battery. Two roller mechanisms for controlling the entry and exit of the therapeutic instruments are provided on the right side of the top surface of the triangular housing. The roller mechanisms are controlled to rotate forward or backward by the foot pedal control device. The operation panel is located on the top surface of the triangular housing, and the control board and the battery are located inside the triangular housing. The roller mechanisms and the operation panel are electrically connected to the control board.

[0006] The innovation of this invention is to provide doctors with an electrically controlled device for the entry and exit of endoscopic therapeutic instruments. This device adds another "hand" to the doctor, enabling the surgeon to precisely control the entry and exit of different therapeutic instruments to perform operations such as grasping suspected lesions, removing digestive tract tumors, and closing digestive tract wounds.

[0007] Furthermore, the left side of the triangular housing is provided with a large groove that matches the outer surface of the endoscope operating part, and the right side of the triangular housing is provided with a small groove that matches the outer surface of the instrument forceps passage. The large and small grooves make the triangular housing more stable to install. Two roller mechanisms are distributed on both sides of the center line of the small groove, ensuring that the two roller mechanisms can clamp the body of the treatment instrument, and the movement of the treatment instrument is controlled by the rolling of the roller mechanisms.

[0008] Furthermore, the roller mechanism includes a hinge support, a motor, and a roller. The motor is mounted on the hinge support, and under the action of the hinge support, the motor can rotate back and forth around the hinge point. The roller is mounted on the output shaft of the motor. The angle between the axis of the roller and the center line of the small groove is a right angle, realizing the linear transport of the body of the treatment device. A torque sensor is mounted on the motor, and the torque sensor is used to monitor the change of the torsional force of the motor spindle to determine whether the transport of the treatment device is normal.

[0009] Furthermore, it also includes a separation device, which is used to control the merging or separation of the two roller mechanisms. When the two roller mechanisms are merged, they can clamp the body of the treatment instrument. When the two roller mechanisms are separated, the treatment instrument can be replaced. The separation device includes an electromagnet and a magnet. The electromagnet is set in the middle of the two roller mechanisms. A magnet that works with the electromagnet is set on the hinge support. By controlling the direction of the current on the electromagnet to change the N pole or S pole, the magnet can be attracted or separated from the roller mechanism, thereby achieving contact or separation control.

[0010] Furthermore, the control panel is equipped with a power switch, a Bluetooth signal pairing button, a launch button, a speed adjustment button, and indicator lights.

[0011] Furthermore, it also includes a locking mechanism, on which the small groove is provided a locking mechanism for gripping the instrument forceps mouth; the locking mechanism is a right-angle lever, the corner of the right-angle lever is rotatably connected to the side of the small groove with damping, and the locking or unlocking of the triangular housing on the instrument forceps mouth is realized by the rotation of the right-angle lever, so as to realize the detachable installation of the main control device.

[0012] Furthermore, the foot pedal control device includes a right-angle base, an inner cavity, a rotating shaft, a foot pedal, a rocker arm, female terminal blocks, male terminal blocks, a neutral magnet, a second control board, and a second battery. The vertical section of the right-angle base has an inner cavity. A rotating shaft is rotatably mounted within the inner cavity, with the foot pedal and rocker arm mounted on it, arranged horizontally side-by-side on both sides of the shaft. Two male terminal blocks are positioned vertically at the front end of the rocker arm, and female terminal blocks are positioned on the top and bottom surfaces of the inner cavity, with the female terminal blocks directly above or below the male terminal blocks. Neutral magnets are embedded in both the female and male terminal blocks. The second control board and the second battery are housed within the right-angle base. Two circuits are set on the foot pedal control device. Pressing down or lifting up the foot pedal can separate the contact between the female and male terminals, thus disconnecting or connecting the two circuits. Connecting one circuit controls the forward rotation of the roller mechanism, and connecting the other circuit controls the reverse rotation of the roller mechanism.

[0013] Furthermore, the horizontal section of the right-angle base is 15.0cm to 20.0cm longer than the foot pedal, providing sufficient space for the foot to step on and preventing the foot from being suspended in the air, which would affect the operation of lifting the foot pedal; the top surface of the foot pedal is 6.0cm to 8.0cm away from the horizontal section of the right-angle base, providing sufficient space for the toes to be inserted into the bottom of the foot pedal.

[0014] Furthermore, the bottom surface of the right-angle base is provided with an anti-slip pad or suction cup to ensure that the foot pedal control device is not easily moved.

[0015] Furthermore, it also includes a wireless charging coil. Both the triangular housing and the right-angled base are equipped with wireless charging coils, which enable wireless charging of the battery, reducing the need for connection ports and cables.

[0016] The advantages of this invention are as follows: This invention uses a roller mechanism on the main control device and a foot pedal control device to achieve electric control of the body of the treatment instrument on the endoscope; in particular, it adjusts the position of the treatment instrument to accurately grasp suspected lesions, remove digestive tract tumors, close digestive tract wounds, etc., giving the surgeon an extra "hand". The surgeon and the control operation of the treatment instrument can be completed by one person, with precise operation, reducing reliance on assistants and increasing the accuracy of the surgeon's operation of the endoscope and treatment instrument.

[0026] The present invention will now be described in detail with reference to the accompanying drawings:

[0027] In the description of this invention, it should be noted that the orientation or positional relationship indicated by terms such as "upper", "lower", "top", and "bottom" is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the product of this invention is usually placed in during use. It is only for the convenience of describing this invention and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or a specific orientational structure and operation. Therefore, it should not be construed as a limitation of this invention.

[0028] like Figure 1-5As shown, an electrically controlled device for the entry and exit of endoscopic therapeutic instruments includes a main control unit and a foot pedal control unit. The main control unit is detachably installed in a V-shaped fork between the operating part of the endoscope and the instrument forceps port. The main control unit allows control of the entry and exit of the therapeutic instrument, especially when controlling the instrument to approach the lesion, enabling the surgeon to precisely control the advancement (closer to the lesion) or retraction of the instrument tip according to their own habits. The main control unit is wirelessly connected to the foot pedal control unit, which replaces manual operation, transforming the control of the instrument's entry and exit from manual to foot-operated; that is, the main control unit is operated via the foot pedal control unit.

[0029] The main control device includes a triangular housing 1, a roller mechanism 2, an operation panel 3, a control board 4, a battery 5, a large groove 6, a small groove 7, a separation device 8, and a locking mechanism 9. The left side of the triangular housing 1 is provided with a large groove 6 that matches the outer surface of the endoscope operating part, and the right side of the triangular housing 1 is provided with a small groove 7 that matches the outer surface of the instrument forceps channel. The function of the large groove 6 and the small groove 7 is to ensure that the triangular housing 1 can be stably installed on the endoscope in the V-shaped fork between the operating part and the instrument forceps channel without loosening. The small groove 7 is equipped with a locking mechanism 9 for gripping the instrument forceps opening. The locking and unlocking of the locking mechanism 9 secures the triangular housing 1. The locking mechanism 9 is a right-angle lever, which is damped and rotatably mounted on the side of the small groove 7 around its right-angle inflection point. Rotation of the right-angle lever locks or unlocks the instrument forceps opening. The damped rotation of the right-angle lever ensures it can only rotate under external force, preventing loosening and instability. Two roller mechanisms 2 for controlling the movement of treatment instruments are located on the right side of the top surface of the triangular housing 1, distributed on either side of the centerline of the small groove 7. Each roller mechanism 2 includes a hinge support 21, a motor 22, and a roller 23. The bottom of the hinge support 21 is hinged to the top surface of the triangular housing 1, and the hinge support 21 can rotate back and forth. A motor 22, a brushless motor, is mounted on the hinge support 21. A roller 23 is mounted on the output shaft of the motor 22. The axis of the roller 23 forms a right angle with the center line of the small groove 7, ensuring that the therapeutic instrument can move in and out along the center line of the forceps opening when the roller 23 applies force. The roller 23 is made of rubber, ensuring sufficient friction between it and the therapeutic instrument while minimizing damage from the interaction forces. A torque sensor is mounted on the motor 22 to monitor changes in the torsional force of the motor 22's main shaft.

[0030] The separation device 8 is used to control the merging or separation of the two roller mechanisms 2. When the two roller mechanisms 2 are merged (close together), the roller 23 can clamp the treatment instrument. The forward or reverse rotation of the roller 23 can control the entry or exit of the treatment instrument. When the two roller mechanisms 2 are separated, the treatment instrument can be easily removed and replaced. The separation device 8 includes an electromagnet 81 and a magnet 82. The electromagnet 81 is located between the two roller mechanisms 2. The magnet 82, which works in conjunction with the electromagnet 81, is provided on the hinge support 21. When it is necessary to merge the two roller mechanisms 2, simply stand the two roller mechanisms 2 upright, and the magnet 82 will be attracted to the electromagnet 81. When the electromagnet 81 is energized, it will generate a magnetic field that is opposite to that of the magnet 82. When it is necessary to separate the two roller mechanisms 2, simply change the direction of the current in the electromagnet 81 to generate a magnetic field that is the same as that of the magnet 82, thus separating the two roller mechanisms 2.

[0031] The operation panel 3 is located on the top surface of the triangular housing 1. The operation panel 3 is equipped with a power switch, a Bluetooth signal pairing button, a eject button, a speed adjustment button, and indicator lights. The power switch is used to turn the machine on and off; the Bluetooth signal pairing button is used to pair the Bluetooth signal with the foot pedal control device; the eject button is used to control the operation of the electromagnet 81 to separate the two roller mechanisms 2; the speed adjustment button is used to adjust the rotation speed of the roller mechanism 2 to meet the operating habits of different doctors; the indicator lights are color-changing LED lights, divided into red, yellow, and green lights. A red light indicates that the Bluetooth signal pairing is unsuccessful or there is a malfunction, a yellow light indicates that the battery power is low, and a green light indicates that the machine is in normal working condition.

[0032] The control board 4 and the battery 5 are housed inside the triangular housing 1. The roller mechanism 2, the operation panel 3, and the electromagnet 81 are electrically connected to the control board 4. Both the control board 4 and the foot pedal control device of the main control device are equipped with wireless communication modules. The foot pedal control device indirectly controls the forward or reverse rotation of the roller mechanism 2 through a wireless communication connection (Bluetooth signal connection) with the control board 4.

[0033] like Figure 6-9As shown, the foot pedal control device includes a right-angle base 10, an inner cavity 11, a rotating shaft 12, a foot pedal 13, a rocker arm 14, a female terminal block 15, a male terminal block 16, an N-pole magnet 17, a second control board 18, and a second battery 19. The vertical section of the right-angle base 10 has an inner cavity 11, within which the rotating shaft 12 is rotatably mounted. The foot pedal 13 and rocker arm 14 are mounted on the rotating shaft 12, arranged horizontally side-by-side on both sides of the rotating shaft 12, with a structure similar to a seesaw. To facilitate foot pedal operation, the horizontal section of the right-angle base 10 is 15.0cm to 20.0cm longer than the foot pedal 13; the top surface of the foot pedal 13 is 6.0cm to 8.0cm away from the top surface of the horizontal section of the right-angle base 10. To ensure the stability of the foot pedal control device, an anti-slip pad or suction cup is provided on the bottom surface of the right-angle base 10; the suction cup can be an electric suction cup.

[0034] Two male terminal blocks 16 are positioned at the top and bottom of the rocker arm 14. Female terminal blocks 15 are positioned on the top and bottom surfaces of the inner cavity 11, with each female terminal block 15 located directly above or below the male terminal blocks 16. Each female terminal block 15 is paired with one male terminal block 16, and contact between them establishes a circuit. Two circuits are provided on the foot pedal control device, controlling the forward or reverse rotation of the roller mechanism 2. The female terminal block 15 uses a circular electrode plate, positioned at the center of the cylindrical terminal block base. The male terminal block 16 uses a spring-loaded terminal, also positioned at the center of the cylindrical terminal block, ensuring soft contact between the female and male terminal blocks 15. An N-pole magnet 17 is embedded in both the female and male terminal blocks 15. The annular N-pole magnet 17 is embedded in the end face of the terminal block. Therefore, each terminal block consists of a cylindrical terminal block base, an N-pole magnet, and a circular electrode plate or a spring-loaded terminal. The female terminal 15 and male terminal 16 are spaced 0.5cm to 1.0cm apart. The principle of magnetic repulsion is used to maintain the separation of the female terminal 15 and male terminal 16 under normal conditions and to keep the foot pedal 13 horizontal. When it is necessary for the female terminal 15 and male terminal 16 to connect the circuit, simply step down or lift the foot pedal 13. The control board 2 18 and the battery 2 19 are housed within the right-angle base 10, and the female terminal 15 and male terminal 16 are electrically connected to the control board 2 18. A control panel is also provided on the side of the foot pedal control device, featuring a power switch, a Bluetooth signal pairing button, and indicator lights. Only one Bluetooth signal can be paired between the main control device and the foot pedal control device at a time, prioritizing the closest pair.

[0035] The main control unit needs to be waterproofed for easy disinfection and reuse. Wireless charging coils 20 are installed inside both the triangular housing 1 and the right-angled base 10 to facilitate battery charging.

[0036] Specific operating steps: 1. Install the main control device on the endoscope; 2. Turn on the main control device and foot pedal control device and pair the Bluetooth signal; 3. After inserting the treatment instrument body into the instrument forceps channel of the endoscope, flip the two roller mechanisms to clamp the forceps body; 4. When precise control of the treatment instrument's entry and exit near or away from the lesion tissue is required, use the foot pedal or the upward-tilting foot pedal to control the entry and exit of the treatment instrument at the front end of the endoscope. If the treatment instrument's entry and exit is obstructed due to operational errors during operation, the rotation of motor 22 will be hindered. The torque sensor on motor 22 can monitor the slight change in the main shaft torque when motor 22 is obstructed. If the change in torque exceeds the preset change value range, control board 4 will control roller mechanism 2 to stop working. During the stoppage, it is not controlled by the foot pedal control device; after stopping, it needs to be manually restarted before normal use.

[0037] Although the specific embodiments of the present invention have been described and illustrated in detail above, it should be noted that various changes and modifications can be made to the above embodiments without departing from the spirit of the present invention and the scope set forth in the appended claims.
