Description

Technical Field

[0001] The present invention relates to the field of medical plastic surgery technology, and in particular to a swelling fluid injection device and method. Background Art

[0002] Liposuction is a type of body sculpting surgery that uses physical means such as ultrasound and high-frequency electric fields to break up fat, and then inserts a liposuction tube into the subcutaneous fat layer through a small incision in the skin. The suction force of negative pressure is used to remove the subcutaneous fat that has accumulated locally in the human body, in order to achieve weight loss and improve body shape. Common areas for whole-body liposuction include: face, double chin, neck, shoulders and back, limbs, hands and feet, upper and lower abdomen, side waist, upper buttocks, buttocks reduction and buttocks lifting, etc. Liposuction is a type of body sculpting surgery in plastic surgery. The principle is to use negative pressure to suck out excess fat from a certain part of the body, in order to achieve the purpose of local rapid weight loss. Whole-body liposuction weight loss surgery should follow the principle of "small amounts and multiple times". Fewer suction areas will result in less trauma, faster recovery, less pain, and no need for general anesthesia.

[0003] For example, when sucking abdominal fat, the range of abdominal liposuction and the location of the incision are generally marked with a marker, and then local anesthesia is performed within the marked range of the abdomen. The incision is usually made at the navel or above the pubic symphysis, and the incision length is about one to two centimeters, which is appropriate for inserting a suction tube. After making multiple incisions in the abdomen, the needle is manually inserted into the abdominal fat layer through the incision through a syringe, and swelling fluid is injected to swell the fat tissue to facilitate the suction of fat. The swelling fluid contains local anesthetics, hemostatic agents and other ingredients, which can relieve pain and reduce bleeding. Finally, the liposuction tube is inserted through the incision to suck the fat.

[0004] However, when injecting the tumescent fluid through a syringe, due to the differences in the thickness and distribution of the human body's fat layer, it is difficult for medical staff to accurately find the middle of the fat layer each time they inject, resulting in the tumescent fluid being injected too shallowly or too deeply, thereby reducing the direct contact area with the fat tissue, making it difficult for the tumescent fluid to be evenly distributed in the fat layer, causing unevenness during subsequent fat aspiration, and increasing the difficulty of the operation and the risk of complications. Summary of the invention

[0005] The object of the present invention is to provide a tumescent fluid injection device and method to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the present invention provides a method for injecting swelling fluid, comprising the following steps:

[0007] Precise injection: Place the device on the abdomen, align the needle hole with the incision, rotate the second handle to generate negative pressure to fix it, and then rotate the first handle to control the position of the positioning disk through the cooperation of the connecting ring and the connecting groove. After the syringe is inserted into the positioning cylinder, the end of the syringe close to the needle is fitted with the fixing cylinder, and the needle passes through the needle hole and is inserted into the fat layer to accurately control the injection position in the abdominal fat layer;

[0008] Gathering fat: During injection, the rotating syringe drives the adjusting disk to rotate, and under the control of the guide groove, the sliding column moves outward, and then the four push plates inclined to the outside are driven by the support rods 1 and 2 to move from the periphery of the injection point to the inside, squeezing and pushing the fat tissue around the injection point;

[0009] Vibration and diffusion: The roller reduces the friction with the skin and improves comfort. At the same time, when the roller rotates, the protrusions are repeatedly used to lift the slide plate and reset it through the spring, so that the slide plate drives multiple contact rods to continuously vibrate the abdominal skin, shaking off the fat on the moving path of the push plate, making it easier for the push plate to squeeze and push the fat tissue.

[0010] Wherein, during the injection process of the accumulated fat, when the four pushing plates are pushed and moved, the four hemostatic pieces are driven to separate from the incision by the process of the support rod moving obliquely upward to avoid obstruction of the line of sight;

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. When aspirating fat, the position of the positioning disk in the positioning cylinder can be controlled by turning the rotary handle 1, so that when the syringe is subsequently inserted, the injection position of the needle of the syringe in the abdominal fat layer can be controlled through the cooperation of the fixed cylinder to avoid the position where the swelling fluid is injected too shallowly or too deeply, increase the contact area between the swelling fluid and the fat tissue, and allow the swelling fluid to be evenly spread in the fat layer, thereby more effectively softening the fat tissue, which is conducive to improving the subsequent fat extraction efficiency.

[0026] 2. When aspirating fat, the four push plates can be controlled to move from the outside to the inside of the injection site by slowly rotating the syringe during the injection process, thereby squeezing and pushing the fat tissue around the injection site. This operation significantly increases the fat density at the injection site, allowing the tumescent fluid to mix and take effect with more fat tissue. As the fat density gradually increases, the diffusion and penetration of the tumescent fluid at the injection site are more uniform and rapid, and the tumescent fluid can act more effectively on a larger range of fat tissue, achieving better anesthesia, hemostasis and fat softening effects, which is beneficial to improving the subsequent fat extraction effect.

[0027] 3. When the fat is sucked, the shaft and the roller cooperate to reduce the friction with the abdominal skin when the four push plates move from the periphery of the injection point to the inner periphery, thereby reducing the discomfort to the patient. At the same time, the bump and the touch rod cooperate to achieve the effect of continuous vibration of the abdominal skin. On the one hand, the fat is shaken apart by the vibration, so that the push plate can squeeze and push the fat tissue more easily, thereby improving the pushing effect. On the other hand, the fat and swelling fluid being mixed can be promoted to be evenly distributed in the fat tissue, which is beneficial to the subsequent fat suction effect.

[0028] 4. When the device is fixed at the incision position, the incision and the skin around the incision can be covered by four hemostatic pieces, so that the incision can be pre-disinfected during the process of adjusting the depth of the syringe. After the adjustment is completed, the needle will pass through the hemostatic piece into the incision for injection. During the injection process, when the four push plates are pushed and moved, the four hemostatic pieces can be driven to separate from the incision by the process of the support rod moving obliquely upward, avoiding obstruction of vision, ensuring that the injection personnel can observe the incision at any time during the operation, and timely discover and deal with any potential problems;

[0029] Similarly, when the injection is completed and the syringe is taken out, the four push plates will return to their positions, allowing the four hemostatic parts to tightly cover the incision again, which not only helps prevent external contaminants from entering the incision, but also provides additional protection and promotes the healing of the incision.

When it is adjusted to a suitable position, the fixing cylinder 505 is fixedly connected through the inner center of the positioning disk 504, and the top of the fixing cylinder 505 is provided with a needle hole 506 corresponding to the syringe 8, so that the syringe 8 can be inserted into the positioning cylinder 1, so that the end of the syringe 8 close to the needle tip is fitted and positioned with the top of the fixing cylinder 505, and the needle tip of the syringe 8 passes through the needle hole 506 to be inserted into the fat layer of the incision, so as to control the injection position of the needle tip of the syringe 8 in the abdominal fat layer, and avoid the position where the swelling fluid is injected is too shallow or too deep;

[0046] As described above, when the fat is sucked out, the position of the positioning disk 504 in the positioning cylinder 1 can be controlled by rotating the rotary handle 501, so that when the syringe 8 is subsequently inserted, the injection position of the needle of the syringe 8 in the abdominal fat layer can be controlled through the cooperation of the fixed cylinder 505, so as to avoid the swelling fluid being injected too shallowly or too deeply, increase the contact area between the swelling fluid and the fat tissue, and make the swelling fluid evenly diffuse in the fat layer, so as to more effectively soften the fat tissue, which is conducive to improving the subsequent fat extraction efficiency.

[0047] Embodiment 2: Based on the above embodiment, an extrusion and pushing component 6 is provided on the inner wall of the positioning tube 1 .

[0048] Furthermore, the extrusion and pushing component 6 includes an adjusting disk 601, and the inner center of the adjusting disk 601 is rotatably connected to the outer wall of the fixed cylinder 505, the bottom of the syringe 8 is fixedly connected with a snap ring 9 at an equal distance, the top of the adjusting disk 601 is fixedly connected with a clamping block 602 at an equal distance corresponding to the snap ring 9, the top of the adjusting disk 601 is equidistantly penetrated with guide grooves 603, and the inner wall of the guide groove 603 is slidably connected with a sliding column 604, the top of the positioning disk 504 is equidistantly penetrated with a limiting groove 11 corresponding to the sliding column 604, and the outer wall of the sliding column 604 is slidably fitted with the inner wall of the limiting groove 11, the outer wall of the sliding column 604 is symmetrically fixedly connected with a sliding block 2 605, the inner wall of the limiting groove 11 is symmetrically opened with a supporting groove 12 corresponding to the sliding block 2 605, and the outer wall of the sliding block 2 605 is slidably fitted with the inner wall of the supporting groove 12.

[0049] In this embodiment, after the syringe 8 is inserted into the positioning cylinder 1, it is rotatably connected to the outer wall of the fixed cylinder 505 through the inner center of the adjusting disk 601, and the bottom of the syringe 8 is fixedly connected with a retaining ring 9 at an equal distance, and the top of the adjusting disk 601 is fixedly connected with a clamping block 602 at an equal distance corresponding to the retaining ring 9, so that the clamping block 602 can be synchronously inserted into the gap between the three retaining rings 9 to complete the connection, so that during the injection process, the adjusting disk 601 can be synchronously driven to rotate by rotating the syringe 8.

[0050] Then, guide grooves 603 are equidistantly penetrated through the top of the adjusting disk 601, and the inner wall of the guide groove 603 is slidably connected with a sliding column 604, and the top of the positioning disk 504 is equidistantly penetrated with a limiting groove 11 corresponding to the sliding column 604, and at the same time, the outer wall of the sliding column 604 is symmetrically fixedly connected with the inner wall of the limiting groove 11, and the outer wall of the sliding column 604 is symmetrically fixedly connected with a sliding block 2 605, and the inner wall of the limiting groove 11 is symmetrically provided with a supporting groove 12 corresponding to the sliding block 2 605, and at the same time, the outer wall of the sliding block 2 605 is symmetrically fitted with the inner wall of the supporting groove 12, so that the sliding column 604 located in the guide groove 603 can be supported and the moving direction can be limited by the cooperation of the supporting groove 12 and the limiting groove 11, so that when the adjusting disk 601 rotates, the four sliding columns 604 can be controlled to move outward synchronously through the guide groove 603.

[0051] Then, the bottom of the sliding column 604 is symmetrically fixedly connected with the support frame 606, and the outer wall of the side where the two support frames 606 are close to each other is fitted with a connecting rod 607, and the inner wall of the groove 612 is rotatably connected with the second support rod 613, and the outer wall of the second support rod 613 is fixedly connected to the middle of the connecting rod 607, and the other end of the connecting rod 607 is fixedly connected to the top of the pushing plate 4, and one end of the connecting rod 607 is fixedly connected to the inside of the supporting rod 1 608, and the outer wall of the supporting rod 1 608 is fixedly connected to the movable plate 4. The inner walls of the groove 609 fit and slide together, so that when the sliding column 604 moves, the four pushing plates 4 inclined to the outside can be driven to move from the periphery of the injection point to the inside through the support rod 1 608 and the support rod 2 613, so as to produce a squeezing and pushing effect on the fat tissue around the injection point, thereby increasing the fat density at the injection point, allowing the swelling fluid to mix with more fat tissue and take effect. As the fat density gradually increases, the diffusion and penetration of the swelling fluid at the injection point are more uniform and rapid.

[0052] Then, a return torsion spring 614 is provided on the outer wall of the fixed cylinder 505, and one end of the return torsion spring 614 is overlapped on the top of the adjusting disk 601, and the other end of the return torsion spring 614 is overlapped on the outer wall of the fixed cylinder 505, so that when the injection is completed and the syringe 8 is taken out, the return torsion spring 614 can be used to drive the adjusting disk 601 to reset and reverse, so that the four pushing plates 4 return to their positions.

[0053] Then, the driving rod 615 is rotatably connected to the two ends of the support rod 608, and the bottom of the driving rod 615 is fixedly connected to the hemostatic piece 616, so that when the device is fixed at the incision position, the four hemostatic pieces 616 can cover the incision and the skin around the incision, so that the incision can be pre-disinfected during the process of adjusting the depth of the syringe 8. After the adjustment is completed, the needle will pass through the hemostatic piece 616 into the incision for injection. During the injection process, when the four pushing plates 4 are pushed and moved, the process of the support rod 608 moving obliquely upward can be used to drive the four hemostatic pieces 616 to separate from the incision to avoid obstruction of the line of sight, ensuring that the injection personnel can observe the condition of the incision at any time during the operation, and promptly discover and deal with any potential problems. Similarly, when the injection is completed and the syringe 8 is taken out, the four pushing plates 4 will return to their positions, so that the four hemostatic pieces 616 are tightly covered on the incision again, which not only helps to prevent external contaminants from entering the incision, but also provides additional protection and promotes the healing of the incision.

[0054] It is worth mentioning that an arc-shaped notch is left at the position where the four hemostatic parts 616 are close to each other, and the diameter of the arc-shaped notch after being combined is slightly larger than the diameter of the needle, so that the needle can pass through the arc-shaped notch during the insertion of the syringe 8. At the same time, the hemostatic part 616 is specifically a plate body with an arc-shaped notch, and the surface of the plate body is provided with a hemostatic cotton pad, and it can also be a clamping component that can clamp the hemostatic cotton, wherein the hemostatic cotton and the hemostatic cotton pad can be stained with disinfectant alcohol or other disinfectable media.

[0055] Furthermore, the degree of fit between the four push plates 4 and the abdominal skin is related to the position of the positioning plate 504 in the positioning cylinder 1. When the syringe 8 is inserted deeper, it usually means that the fat layer is thicker, and the positioning plate 504 will be relatively located below the positioning cylinder 1, so that the push plates 4 are driven by the positioning plates 504 to fit better with the abdominal skin, thereby relatively improving the squeezing effect on the abdomen and avoiding inadequate squeezing. Similarly, if the fat layer is thin and the syringe 8 is inserted relatively shallowly, the push plates 4 will not fit the abdominal skin excessively, thus avoiding unnecessary squeezing and damage, and ensuring that the swelling fluid can be fully mixed with the fat tissue under different fat thicknesses, thereby improving the efficiency and uniformity of fat extraction.

[0056] As described above, when the fat is sucked out, the four pushing plates 4 can be controlled to move from the periphery to the inner periphery of the injection point by slowly rotating the syringe 8 during the injection process, thereby squeezing and pushing the fat tissue around the injection point. This operation significantly increases the fat density at the injection point, allowing the swelling fluid to mix with more fat tissue and take effect. As the fat density gradually increases, the diffusion and penetration of the swelling fluid at the injection point are more uniform and rapid, and the swelling fluid can act more effectively on a larger range of fat tissue, achieving better anesthesia, hemostasis and fat softening effects, which is beneficial to improving the subsequent fat extraction effect.

[0057] It is worth mentioning that in this case, local anesthesia was performed on the abdomen before the swelling fluid was injected into the patient's incision. At the same time, the number of rotations required to insert the block 602 into the three clamping rings 9 and the total number of rotations required for rotational injection were approximately two to three weeks, so the intraoperative impact on the patient was minimal.

[0058] Embodiment 3: Based on the above embodiment, a dispersion auxiliary component 7 is provided at the bottom of the pushing plate 4 .

[0059] Furthermore, the dispersion auxiliary component 7 includes a shell 701, the tops of several shells 701 are fixedly connected to the bottom of the push plate 4, and the shell 701 is internally rotatably connected to an axle rod 702, both ends of the axle rod 702 are fixedly connected to rollers 703, the inner wall of the shell 701 is slidably connected to a slide plate 704, and the top of the slide plate 704 is fixedly connected to a spring 705, the other end of the spring 705 is fixedly connected to the top inner wall of the shell 701, and the outer wall of the axle rod 702 is fixedly connected to a protrusion 706 corresponding to the slide plate 704.

[0060] In this embodiment, when the pushing plate 4 moves, the shaft rod 702 can be connected by rotating inside the shell 701, and the two ends of the shaft rod 702 are fixedly connected to the rollers 703, so that the rollers 703 can be used to squeeze and push the abdominal skin instead of the pushing plate 4, reducing the friction with the abdominal skin and reducing the discomfort to the patient. At the same time, during the rotation of the roller 703, the slide plate 704 is slidably connected through the inner wall of the shell 701, and the top of the slide plate 704 is fixedly connected to the spring 705, and the other end of the spring 705 is fixedly connected to the top inner wall of the shell 701, and the outer wall of the shaft rod 702 is fixedly connected to the slide plate 704 corresponding to the protrusion 706, so that The protrusion 706 can be driven by the shaft 702 to rotate continuously to lift the slide plate 704, and then the slide plate 704 can be driven to reset by the spring 705. At this time, the bottom of the slide plate 704 is fixedly connected with the touch rod 707 at equal distances, and the bottom of the shell 701 is equidistantly penetrated with a through groove 708 corresponding to the touch rod 707, and the outer wall of the touch rod 707 is fitted and slid with the inner wall of the through groove 708. At the same time, the bottom of the touch rod 707 is semicircular, so that the slide plate 704 can drive multiple touch rods 707 to achieve the effect of continuous vibration of the abdominal skin, and the fat on the moving path of the push plate 4 can be shaken off, so that the push plate 4 can squeeze and push the fat tissue more easily.

[0061] As described above, when the fat is sucked, the shaft 702 and the roller 703 cooperate with each other, so that when the four push plates 4 move from the outer periphery of the injection point to the inner periphery, the friction with the abdominal skin can be reduced, thereby reducing the discomfort to the patient. At the same time, the bump 706 and the touch rod 707 cooperate to achieve the effect of continuous vibration of the abdominal skin. On the one hand, the fat is shaken apart by the vibration, so that the push plate 4 can squeeze and push the fat tissue more easily, thereby improving the pushing effect. On the other hand, the fat and swelling fluid being mixed can be promoted to be evenly distributed in the fat tissue, which is beneficial to the subsequent fat suction effect.

[0062] The specific process of a tumescent fluid injection method is as follows:

[0063] First, place the device on the abdomen with the needle hole 506 facing the incision position. Then, negative pressure can be generated in the cylinder 1301 by rotating the second handle 1304, and the device can be fixed on the abdomen by atmospheric pressure. Then, the position of the abdominal fat layer is confirmed, and the connecting ring 503 is driven to rotate and move up and down by rotating the first handle 501, so that the position of the positioning disk 504 in the positioning cylinder 1 can be controlled by rotating the first handle 501 through the cooperation between the connecting ring 503 and the connecting groove 509. When it is adjusted to a suitable position, the syringe 8 can be inserted into the positioning cylinder 1, so that the end of the syringe 8 close to the needle tip is fitted and positioned with the top of the fixed cylinder 505, and the needle tip of the syringe 8 is passed through the needle hole 506 to be inserted into the fat layer of the incision, so as to control the injection position of the needle tip of the syringe 8 in the abdominal fat layer, and cover the incision and the skin around the incision through four hemostatic members 616;

[0064] Then, after the syringe 8 is inserted into the positioning cylinder 1, during the injection process, the adjusting disk 601 can be synchronously driven to rotate by rotating the syringe 8, and the slide column 604 located in the guide groove 603 can be supported and the moving direction can be limited by the cooperation of the support groove 12 and the limit groove 11, so that when the adjusting disk 601 rotates, the four slide columns 604 can be controlled to move synchronously outward through the guide groove 603. When the slide column 604 moves, the four push plates 4 inclined to the outside can be driven to move from the periphery of the injection point to the inside through the support rod 1 608 and the support rod 2 613, so as to produce a squeezing and pushing effect on the fat tissue around the injection point, and at the same time, the four hemostatic pieces 616 can be driven to separate from the incision by the process of the oblique upward movement of the support rod 1 608 to avoid obstruction of the line of sight;

[0065] When the push plate 4 moves, the roller 703 can be used to replace the push plate 4 to squeeze and push the abdominal skin, thereby reducing the friction with the abdominal skin and reducing the discomfort to the patient. At the same time, during the rotation of the roller 703, the shaft 702 can drive the protrusion 706 to rotate continuously to lift the slide plate 704, and then the spring 705 can drive the slide plate 704 to reset, so that the slide plate 704 can drive the multiple contact rods 707 to achieve the effect of continuously vibrating the abdominal skin, and the fat on the moving path of the push plate 4 can be shaken off, so that the push plate 4 can squeeze and push the fat tissue more easily.

[0066] Finally, when the injection is completed and the syringe 8 is taken out, the four push plates 4 will return to their positions, so that the four hemostatic members 616 will cover the incision tightly again, which not only helps to prevent external contaminants from entering the incision, but also provides additional protection and promotes the healing of the incision.
