Description

Technical Field

[0001] The present invention relates to the technical field of liposuction devices, in particular to a medical plastic surgery minimally invasive liposuction device. Background Art

[0002] Plastic surgery liposuction is a surgical procedure that uses physical and chemical means such as negative pressure suction and / or ultrasound, high-frequency electric fields, etc. to remove pre-treated subcutaneous fat deposited in the human body through a small skin incision or puncture, and combines it with techniques such as fat particle injection and transplantation to improve the body shape.

[0003] The most common technical solution at present is a negative pressure suction liposuction device. The usual operating steps are: after the doctor injects tumescent fluid into the area to be sucked where the patient's fat is accumulated, he inserts the liposuction tube into the subcutaneous fat layer. The doctor holds the liposuction tube and makes reciprocating movements in the patient's subcutaneous fat layer. Under the negative pressure suction of the liposuction machine, the fat flows out from the patient's subcutaneous tissue, and then the suction device sucks the outflowing fat to complete the liposuction process. However, the current liposuction equipment has certain defects. First, if the fat blocks the suction port, the negative pressure device is always working, so the suction force of the negative pressure at the position of the suction port will become greater and greater. When the negative pressure value reaches a certain value, the blocked fat will be instantly sucked away, but at this time the position of the suction port is still accompanied by a high negative pressure state. Therefore, after the blocked fat is sucked out, the suction port may still be in a high negative pressure state to suck the remaining subcutaneous tissue, which can easily cause damage to the remaining subcutaneous tissue. Therefore, a medical plastic surgery minimally invasive liposuction device is proposed to solve the above-mentioned problems. Summary of the Invention

DETAILED DESCRIPTION

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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.

[0020] See also Figures 1-9 A medical plastic surgery minimally invasive liposuction device includes a negative pressure machine 1 for generating negative pressure airflow; a collection tank 3 for collecting sucked fat; a diversion component 6 for penetrating into the patient's subcutaneous tissue to achieve protective absorption of the fat layer; the diversion component 6 includes a suction protection device, a mincing and drainage device and an adjustment device; the suction protection device can perform protective liposuction on the blockage high pressure caused by the liposuction process; the mincing and drainage device is used to crush and drain the sucked fat; the adjustment device is used to adjust the crushing pressure of the mincing and drainage device.

[0021] In this embodiment, the suction protection device includes a handle 603, one end of which is connected to a flow guide tube 601, a central tube 604 inserted into the interior of the handle 603, an inlet 6051 formed on the end surface of the central tube 604, one end of which is connected to the negative pressure machine 1, a sleeve 602 slidably connected to the surface of the central tube 604, the sleeve 602 being fixed to the handle 603, a compression spring 608 sleeved on the surface of the central tube 604 located inside the handle 603, one end of the compression spring 608 being connected to a spring plate 623, the other end of the compression spring 608 being abutted against the interior of the handle 603, and the spring plate 623 being fixed to the surface of the central tube 604. The position of the sleeve 602 is fixed, and when the central tube 604 slides and contracts laterally, it forms a sliding cutting state with the sleeve 602, thereby achieving a blockage cutting effect. At this time, the air inlet position will be the position of the air inlet 612. When the blockage is eliminated, the spring plate 623 will be pushed back to its original position by the restoring force of the compression spring 608, thereby driving the central tube 604 to slide right and reset, thereby converting the normal suction force to the position of the inlet 6051 again, and realizing the liposuction process again. Furthermore, the right end of the sleeve 602 is connected to a ball head 606. The purpose of the ball head 606 is to improve the smoothness of the scraping when the entire sleeve 602 penetrates the subcutaneous tissue. The ball head 606 has an opening 607. The interior of the sleeve 602 is provided with an air inlet cavity 620. The interior of the handle 603 is provided with an air cavity 605. The interior of the sleeve 602 is provided with a fracture 621. The surface of the sleeve 602 is connected to a connecting tube 624. One end of the connecting tube 624 is connected to the air cavity 605. The handle 603 is connected to the air inlet 612 located inside the air cavity 605. If the position of the inlet 6051 is blocked, the piston plate 609 will slide to the left, and when the piston plate 609 slides to the left, the central tube 604 will be driven to shrink inside the sleeve 602. During the shrinkage process, the inlet 6051 of the central tube 604 will slide horizontally into the position of the fracture 621. Therefore, the suction force of the inlet 6051 will be transferred to the inside of the air inlet cavity 620 through the connection of the fracture 621. Then, the high-pressure suction force of the port will be converted to the position of the air inlet 612 through the connection between the connecting tube 624 and the air cavity 605. The air inlet 612 is facing the outside world, thereby protecting the liposuction process from blockage and shrinkage.

[0022] Furthermore, the left side of the handle 603 is connected to a tailstock 610, and a flow chamber is provided inside the tailstock 610. A piston plate 609 is slidably connected inside the flow chamber, and a plurality of flow ports are provided on the left side of the piston plate 609. The mincing device includes a mincing blade 611, which is located inside the flow chamber and is rotatably connected to the piston plate 609 via a connecting rod. The sucked fat will follow the position of the central tube 604 to the position of the piston plate 609 and be discharged from the left hole of the piston plate 609 into the flow chamber. As the fat is sucked and flows, the mincing blade 611 will be driven to rotate by the flow force. Therefore, when the fat flows, the mincing blade 611 can use the suction force generated by the negative pressure to automatically rotate and cut the mincing blade 611, ensuring that the fat will not cause internal blockage when it flows in the pipeline. And when the central tube 604 moves laterally to the left, the piston plate 609 will move laterally synchronously, thereby sealing the position of the interface 622. Therefore, in the blocked environment of the inlet 6051, the interface 622 can be automatically blocked, and all the suction force of the negative pressure machine 1 can be transferred to the inside of the central tube 604, realizing high-pressure suction and reducing the probability of blockage.

[0023] In addition, an interface 622 is provided inside the tailstock 610. One end of the interface 622 is connected to the outside world, and the other end of the interface 622 is connected to the flow chamber. The piston plate 609 is located to the right of the interface 622. Through the provided interface 622, the negative pressure generated by the negative pressure machine 1 can be converted into a dual channel, with part of the negative pressure converted to control the rotation of the mincing blades 611 and part converted into the suction force of the central tube 604. The operator can then control the blocking of the interface 622 to regulate the negative pressure suction force on the central tube 604. The adjustment device includes a wheel 613, which is rotatably connected to the tailstock 610. There are multiple interfaces 622, and the multiple interfaces 622 are distributed in a circular array with the center of the tailstock 610 as the axis of symmetry. The wheel 613 is provided with a first pair of interfaces 614 that cooperate with the multiple interfaces 622. The wheel 613 is magnetically connected to the tailstock 610. Multiple interfaces 622 are provided, and a portion of the negative pressure airflow will flow in from the interface 622. If the inlet 6051 of the central tube 604 is blocked, the airflow will still be drawn in from the interface 622, thereby always maintaining the suction flow of fat by the guide tube 601, and the mincing blade 611 will not stop rotating due to the blockage of the inlet 6051.

[0024] In addition, the wheel 613 is also provided with three second docking ports 615 and one third docking port 616. After the wheel 613 rotates 20 degrees, the three second docking ports 615 will mate with the port 622. After the wheel 613 rotates 40 degrees, the third docking port 616 will mate with the port 622. After the wheel 613 rotates 60 degrees, the multiple ports 622 will be completely blocked. To reduce the number of flow holes of the airflow and increase the flow suction force, the operator needs to manually control the rotation of the wheel 613, rotating the six holes, three holes, one hole, or directly closing the hole, so that the negative pressure of the negative pressure machine 1 is completely transferred to the central tube 604. Therefore, by changing the number of connection holes, the negative pressure value of the negative pressure machine 1 on the central tube 604 can be changed to achieve negative pressure regulation.

[0025] It is worth noting that a display device is also included, including a display dial 617. The inner wall of the display dial 617 is provided with a spiral groove 618. The display dial 617 is rotatably connected to the right end of the handle 603. A sliding pin 619 is slidably connected within the spiral groove 618 and fixed to the surface of the central tube 604. To indicate the negative pressure state during the blockage process, when the inlet 6051 of the central tube 604 is blocked, the central tube 604 moves laterally, driving the synchronous movement of the sliding pin 619. The sliding of the sliding pin 619 within the spiral groove 618 drives the rotation of the display dial 617, converting the lateral sliding force into rotational force. The display dial 617 is provided with scale lines. The operator can view the sliding distance of the central tube 604 at that time based on the rotation of the display dial 617. The rotation angle of the display dial 617 is also displayed, indicating the suction force of the negative pressure blockage at that time, providing a certain reference data for the operator's hand fat hanging operation.

[0026] It is worth noting that the diversion assembly 6 is provided in two groups. The base 2 is provided on the vacuum machine 1, and the collection tank 3 is provided on the base 2. The collection tank 3 is connected to the vacuum machine 1 via a conduit 5. The vacuum machine 1 is provided with a handle 4. The fat extracted by the vacuum machine 1 will flow into the collection tank 3 through the conduit 5. When a certain amount of fat is extracted, the operator can pour out the fat inside the collection tank 3 for processing or replacement to continue liposuction. The collection tank 3 is detachably connected to the base 2, making it easy to take and put the sucked fat.

[0027] The working principle is that when the entire device is in use, the negative pressure device 1 generates negative pressure suction, which is transmitted to the inside of the handle 603 through the guide tube 601 and indirectly to the inside of the central tube 604. The port of the central tube 604 is provided with an inlet 6051, so the negative pressure suction will suck the fat from the position of the inlet 6051. The entire central tube 604 and the cannula 602 directly penetrate into the patient's subcutaneous tissue, that is, the space in the fat layer. The sucked fat will follow the position of the central tube 604 and enter the position of the piston plate 609, and be discharged from the left hole of the piston plate 609 into the interior of the flow chamber. As the fat is sucked and flows, the flow force will drive the mincing blades 611 to rotate. Therefore, when the fat flows, the mincing blades 611 can use the suction generated by the negative pressure to automatically rotate and cut the mincing blades 611, ensuring that the fat will not cause internal blockage when it flows in the pipe. The technical solution is also provided with an adjustment device, which is mainly used to solve the blockage problem at the port during liposuction. Because after the blockage, if there is no airflow inside the central tube 604, a high negative pressure state will be generated. If there is no airflow, the mincing blades 611 will not have the power to rotate, and the fat in the flow cavity cannot be cut. Therefore, multiple interfaces 622 are provided. At this time, a part of the negative pressure airflow will flow in from the position of the interface 622. If the inlet 6051 of the central tube 604 is blocked, the airflow will still be drawn in from the position of the interface 622, thereby always maintaining the suction flow of the fat by the guide tube 601, and the mincing blades 611 will not stop rotating due to the blockage of the inlet 6051. Because the negative pressure machine 1 always generates negative pressure airflow, the fat will not flow out from the position of the interface 622, but can only be sucked in from the position of the guide tube 601. In addition, an adjustment device is provided to adjust the flow pressure of the airflow from the interface 622. When the wheel 613 is in Figure 6When the position is shown, the six first pairs of interfaces 614 will match the positions of the six interfaces 622 to form a conductive state. If you want to reduce the flow holes of the airflow and increase the flow suction force, you can rotate the wheel 613 twenty degrees to connect and match the three second pairs of interfaces 615 with the interfaces 622. So at this time, the six interfaces 622 form a blockage of three holes, leaving only three interfaces 622. If you continue to rotate twenty degrees, there will be only one third pair of interfaces 616 to form a connection match with the interfaces 622. If the operator continues to rotate twenty degrees, the physical part of the wheel 613 will block all the interfaces 622, and the negative pressure airflow will directly form one stream, which will directly act on the position of the inlet 6051. The operator can adjust the number of connected interfaces 622 to adjust the suction pressure of the inlet 6051. Therefore, when the interfaces 622 are connected, the suction generated by the negative pressure will be converted into two suction forces, and the operator can flexibly adjust it according to the liposuction process. And if the position of the inlet 6051 is blocked, the suction force generated by the negative pressure will act on the piston plate 609 in part, and then use the negative pressure suction force to drive the piston plate 609 to slide to the left. When the piston plate 609 slides to the left, it will drive the central tube 604 to shrink inside the sleeve 602. At this time, during the shrinkage process, the position of the inlet 6051 of the central tube 604 will slide horizontally into the position of the fracture 621. Therefore, the suction force of the inlet 6051 will be transferred to the inside of the air inlet chamber 620 through the connection of the fracture 621. Then, through the connection between the connecting pipe 624 and the air cavity 605, the high-pressure suction force of the port will be converted to the position of the air inlet 612, and the air inlet 612 is facing the outside world. Therefore, at this time, due to the blockage of the inlet 6051, the high negative pressure in the tube will be caused, which will change the position of the air inlet. At this time, the air inlet 612, the air cavity 605, the connecting tube 624, the air inlet cavity 620 and the central tube 604 will form a circulation loop, and the entire high-pressure port will not be located inside the subcutaneous tissue, thereby performing blockage and contraction protection during the liposuction process. In addition, when the central tube 604 shrinks and slides laterally, the obstruction at the inlet 6051 position will be cut and separated as the central tube 604 and the sleeve 602 slide laterally, and the position of the sleeve 602 is fixed. When the central tube 604 slides and shrinks laterally, it will form a state similar to sliding cutting with the sleeve 602, thereby achieving the cutting effect of the obstruction. Afterwards, as the negative pressure increases, the blockage will gradually enter the flow cavity from the inside of the central tube 604, and the shredder blades 611 will cut and crush the blockage. At this time, the air intake position will be the position of the air inlet 612. When the blockage is eliminated, the restoring force of the compression spring 608 will push the spring plate 623 to reset, and then drive the central tube 604 to slide right and reset, thereby converting the normal suction force to the position of the inlet 6051 again, and realizing the liposuction process again.The entire process is also equipped with a display device to display the negative pressure status during the blockage process. When the inlet 6051 of the central tube 604 is blocked, the central tube 604 moves laterally, which will drive the synchronous movement of the sliding pin 619. The sliding pin 619 slides inside the spiral groove 618, which will drive the rotation of the display dial 617, converting the lateral sliding force into a rotational force. Scale lines are set on the display dial 617. The operator can check the sliding distance of the central tube 604 at this time according to the rotation of the display dial 617, and at the same time display the rotation angle of the dial 617 to check the negative pressure blockage suction at this time, providing a certain data reference for the operator's hand grease hanging operation.
