Description

Technical Field

[0001] The invention relates to the field of medical devices, and in particular to an automatic liposuction device. Background Art

[0002] Liposuction is a common plastic surgery procedure that is widely used to remove unwanted fat tissue from the human body to create a more ideal body contour. Traditional liposuction surgery relies on doctors to manually operate a liposuction device to extract fat tissue, a process that requires a high degree of technical skills and operating experience.

[0003] Traditional manual liposuction devices have some limitations, including cumbersome operation, low efficiency and increased surgical risks. First, manual operation may lead to prolonged operation time and require doctors to constantly change liposuction heads to adapt to different liposuction sites and tissue characteristics. This not only increases the difficulty of the operation, but also may introduce air or impurities, increasing surgical risks. Second, manual operation is affected by the doctor's skill level and fatigue level, which may lead to unstable operation and affect the consistency and quality of surgical results.

[0004] In addition to the limitations of manual liposuction devices, there are also some automatic liposuction devices on the market. However, these automatic liposuction devices still have some problems, such as slow head replacement speed and complicated operation. At the same time, some automatic liposuction devices are large in size and inconvenient to operate, which makes it difficult to meet the requirements of flexibility and accuracy in surgery.

[0005] Therefore, a new type of automatic liposuction device is proposed, which can overcome some problems of traditional manual and existing automatic liposuction devices, improve surgical efficiency, reduce surgical risks, and improve the consistency and quality of surgical results. This automatic liposuction device should have the function of extracting fat tissue quickly and accurately, and at the same time be easy to operate, safe and reliable, so as to meet the requirements of plastic surgery for efficiency and precision.

[0033] Combine the following Figure 5 , explain the working status of the present invention:

[0034] like Figure 5 As shown in state A, this state is the installation stage state. At this time, the linear push rod is at the uppermost end, the first and second connecting rods in the sealing tube clamping adjustment assembly are in a distant state, and the distance between the first and second sealing tube clamping blocks respectively connected to the first and second connecting rods is greater than the diameter of the sealing tube, which can facilitate the installation of the liposuction syringe assembly. The piston rod in the liposuction syringe assembly and the linear push rod in the drive assembly are tightened by threads to complete the installation.

[0035] like Figure 5As shown in state B, this state is the liposuction working stage state. The linear push rod is driven by the driving motor to move linearly downward, and the first and second connecting rods in the sealing cylinder adjusting assembly gradually approach each other, driving the distance between the first and second sealing cylinder clamping blocks to become smaller, and the sealing cylinder is clamped. Rubber pads are also provided at the ends of the first and second sealing cylinder clamping blocks for controlling the connecting rod trajectory within a certain distance to prevent the sealing cylinder from being clamped and increasing friction. The liposuction working stroke can be adjusted by adjusting the connecting rod component parameters of the sealing cylinder clamping adjusting assembly to increase or decrease the working stroke; at the same time, the third and fourth connecting rods of the piston rod clamping adjusting assembly approach each other due to the action of the tension spring, driving the first and second piston rod clamping blocks to clamp the piston rod.

[0036] like Figure 5 As shown in state C, this state is the disassembly stage state, at this time, the linear push rod moves to the bottom, and the boss on the linear push rod contacts the first and second bearing screws in the piston rod adjustment clamping assembly, so that the third and fourth connecting rods are separated, and the piston rod is loosened; at the same time, at this time, the positions of the first and second connecting rods in the sealing cylinder adjustment clamping assembly also follow the movement of the linear push rod to reach the separation state, loosen the sealing cylinder, and separate the liposuction syringe assembly from the linear push rod by rotation to complete the stitch removal. If you need to continue liposuction work, repeat the above steps and replace the new liposuction syringe assembly.

[0037] Furthermore, the automatic liposuction device is also provided with handles, control switches and other operating components on the base.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
