Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a breast augmentation prosthesis implant. Background Art

[0002] Breast augmentation surgery with implants is a type of plastic surgery that involves surgically implanting prosthetic materials (such as silicone gel, expanded polytetrafluoroethylene, etc.) to increase breast volume and improve breast shape. The implant is usually placed under the mammary gland to achieve good support and aesthetic results. In traditional breast augmentation surgery with implants, implantation usually relies on the doctor to push the implant directly to the predetermined position through a surgical incision. To achieve this process, doctors sometimes use an auxiliary tool called a "conveyor belt." This conveyor belt is designed to guide the implant from the surgical incision to the implantation site to reduce surgical trauma and improve surgical precision. However, there is a significant challenge in the actual operation of this method: the doctor needs to manually squeeze the conveyor belt to push the implant forward. Due to the unevenness of the manual squeezing force, it is difficult to ensure that the implant remains stable and undamaged during the transfer process, thereby increasing the risk of surgical failure.

[0003] Therefore, there is an urgent need for a new breast augmentation prosthesis implant that provides an effective solution to the defects of the existing technology. Utility Model Content

[0022] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0023] Example 1: Please refer to Figures 1 to 6 , a breast augmentation prosthesis implanter includes a prosthesis conveyor belt 1 and an extrusion device 5. The prosthesis conveyor belt 1 is configured as a strip bag structure with openings at both ends. One end of the prosthesis conveyor belt 1 is a prosthesis delivery port 2 and the other end is a prosthesis insertion port 3. The diameter of the prosthesis delivery port 2 is larger than that of the prosthesis insertion port 3. The circumference of each section of the prosthesis conveyor belt 1 gradually narrows from the prosthesis delivery port 2 to the prosthesis insertion port 3; the extrusion device 5 includes a bracket 7, a fixed roller 8 and a movable roller 9. The fixed roller 8 and the movable roller 9 are both rotatably mounted on the bracket 7. The fixed roller 8 and the movable roller 9 are driven by a motor to rotate in opposite directions and synchronously. The prosthesis conveyor belt 1 is pressed between the fixed roller 8 and the movable roller 9.

[0024] The left and right ends of the opening of the bracket 7 are respectively fixedly installed with a left fixed seat 14 and a right fixed seat 10. The rotation of the fixed roller 8 is connected between the left fixed seat 14 and the right fixed seat 10. The right fixed seat 10 is hinged with a right movable seat 11. The movable roller 9 is rotationally connected between the right movable seat 11 and the left movable seat 15. The left movable seat 15 is detachably fixedly connected to the left fixed seat 14. A first drive motor 12 for driving the fixed roller 8 is installed on the right fixed seat 10, and a second drive motor 13 for driving the movable roller 9 is installed on the right movable seat 11. The first drive motor 12 and the second drive motor 13 rotate in opposite directions and synchronously.

[0025] A handle 6 is provided in the middle of the bracket 7, and a controller and a battery are provided inside the handle 6. A power switch 22 and an advance and retreat button 21 are provided on the shell of the handle 6. The battery supplies power to the first drive motor 12, the second drive motor 13 and the controller, and the advance and retreat button 21 controls the advance and retreat of the extrusion device 5.

[0026] The forward and backward button 21 is a push-type stepless speed regulating button. The greater the pressing amplitude, the greater the forward and backward amplitude of the extrusion device 5.

[0027] A pair of pin holes 18 are provided on the protrusion of the left fixed seat 14, and a pin 20 is slidably installed in the pin hole 18. The head of the pin 20 is set as a spherical joint and extends out of the side wall of the protrusion. A spring 19 is connected between the bottom of the pin 20 and the bottom of the pin hole 18. Snap holes 17 are provided on both sides of the groove of the left movable seat 15. The pin 20 is snap-fitted with the snap holes 17. A top column 16 is slidably installed on the outside of the snap hole 17. Pressing the top column 16 can press the head of the pin 20 into the pin hole 18 to unlock the left movable seat 15.

[0028] Working principle of this embodiment:

[0029] First, the prosthesis to be implanted is placed through the prosthesis delivery port 2 of the prosthesis conveyor belt 1. Because the prosthesis delivery port 2 is designed to be larger than the prosthesis insertion port 3, and the circumference of the prosthesis conveyor belt 1 gradually narrows from the delivery port to the insertion port, this helps to stabilize the prosthesis and prevent it from slipping or shifting during transport. Subsequently, the first drive motor 12 and the second drive motor 13 in the squeezing device 5 are activated. These motors respectively drive the fixed roller 8 and the movable roller 9 on the support 7 in opposite and synchronous rotations. Because the prosthesis conveyor belt 1 is compressed between the fixed roller 8 and the movable roller 9, the conveyor belt begins to move smoothly along its length as the rollers rotate. Driven by the motors, the rotational motion of the movable roller 9 relative to the fixed roller 8 is converted into linear motion of the prosthesis conveyor belt 1, thereby automatically, continuously, and smoothly conveying the prosthesis from the prosthesis delivery port 2 to the prosthesis insertion port 3. This mechanized conveying method not only reduces direct handling of the prosthesis during surgery but also significantly improves the stability and safety of transport. Once the implant is delivered to the implant insertion port 3, the surgeon can precisely push it into the intended implantation position, completing a crucial step in the breast augmentation surgery. Because the entire delivery process is precisely controlled by a motor, surgical trauma is minimized, improving both accuracy and success rates.

[0030] The doctor controls the speed and amplitude of the extrusion device 5 by adjusting the amplitude of the pressing, thereby achieving more precise and flexible operation. The forward and backward button 21 has an integrated pressure sensor that can sense and convert the pressure signal generated when the operator presses the button. When the operator presses the button lightly, the pressure signal generated is weak. After being processed by the control circuit, the signal transmitted to the drive system of the extrusion device 5, such as the motor control module, is also relatively small, causing the extrusion device 5 to move forward and backward at a slower speed. On the contrary, if the operator presses the button hard, the pressure signal generated increases, and the signal transmitted to the drive system is also enhanced, thereby driving the extrusion device 5 to move forward and backward at a faster speed or a larger amplitude. The stepless speed regulation method allows the operator to adjust the movement state of the extrusion device 5 at any time according to the actual surgical needs to achieve the best surgical effect. It not only improves the flexibility and accuracy of the operation, but also reduces the requirements for the operator's skill level, making the operation safer and more reliable.

[0031] Pin 20 slides within pin hole 18, its base connected to the bottom of pin hole 18 via spring 19. Spring 19 provides an upward spring force to pin 20, allowing the ball-shaped joint at the head of pin 20 to naturally extend beyond the raised sidewall when not subject to external forces. When the left movable seat 15 and the left fixed seat 14 are brought together and ready for locking, the engaging holes 17 on either side of the groove in the left movable seat 15 align with the head of pin 20. Under the action of spring 19, the head of pin 20 automatically enters the engaging holes 17, thereby locking the left movable seat 15 and the left fixed seat 14.

[0032] To unlock the left movable seat 15, the spring force of the spring 19 must be overcome, forcing the head of the pin 20 out of the engaging hole 17. A push post 16 is slidably mounted outside the engaging hole 17. When sufficient pressure is applied to the push post 16, the end of the push post 16 pushes the head of the pin 20, causing it to overcome the spring force of the spring 19, move downward, and retract into the pin hole 18. Once the head of the pin 20 is completely clear of the engaging hole 17, the left movable seat 15 can move freely, no longer restricted by the locking mechanism of the left fixed seat 14. To relock the left movable seat 15, simply move the left movable seat 15 to the appropriate position, aligning the engaging hole 17 with the head of the pin 20. Subsequently, under the force of the spring 19, the head of the pin 20 automatically pops out and reenters the engaging hole 17, completing the relocking. This locking and unlocking mechanism ensures a secure and easy-to-operate connection between the left movable seat 15 and the left fixed seat 14, facilitating flexible adjustment of the extrusion device 5.

[0033] This embodiment uses an automated and mechanized prosthesis delivery method that is easy to operate and precisely controlled, reducing the doctor's direct manipulation of the prosthesis during surgery, thereby reducing surgical trauma and facilitating the patient's postoperative recovery.
