Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an abdominal wall fat extraction device. Background Technology

[0002] Abdominal fat removal is a medical cosmetic or plastic surgery procedure that uses a negative pressure device to extract fat from the patient's abdominal wall to achieve abdominal shaping.

[0003] However, existing fat extraction devices are relatively simple in design, equipped only with a negative pressure suction device and a liposuction cannula. In practice, before the surgery, medical staff need to manually inject tumescent fluid into the patient's abdominal fat layer using a syringe to cause the fat cells to swell and separate, facilitating subsequent suction. After the suction procedure, medical staff still need to perform a series of follow-up procedures such as surgical suturing. This process makes it impossible to thoroughly clean the liposuction cannula and other instruments in a timely manner after suction, easily causing fat and other impurities to remain inside the cannula, which greatly inconveniences subsequent cleaning work. Summary of the Invention

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the auxiliary components include a water pump b61, a supply pipe 62, a storage tank b63, an injection pipe 64, a connecting pipe b65, a branch pipe 651, and a hose b67. The water pump b61 is bolted to the left rear side of the mounting plate 2. The supply pipe 62 is connected to the rear side of the water pump b61. The storage tank b63 is bolted to the right rear side of the mounting plate 57. The end of the supply pipe 62 away from the water pump b61 passes through the mounting plate 2 and connects to the storage tank b63. ​​The injection pipe 64 is connected to the front side of the water pump b61. The connecting pipe b65 is welded to the left side of the connecting pipe a40. The end of the injection pipe 64 away from the water pump b61 is connected to the lower end of the connecting pipe b65. The upper part of the liposuction cannula 43... A branch tube 651 is fixed in one piece, and the branch tube 651 passes through the holding column 42. A lumen b66 is opened in the liposuction tube 43, and the lumen b66 is connected to the branch tube 651.

[0029] like Figure 1 and Figure 8As shown, the placement rack 44 includes an upright plate 441, a fixed limiting ring 442, a fixed shaft 443, a rotation limiting ring 444, and a torsion spring 445. The upright plate 441 is fixed to the top front side of the fixed plate 2 by bolts. The fixed limiting ring 442 is welded and fixed to the upper side of the upright plate 441. The fixed shaft 443 is welded and fixed to the right side of the fixed limiting ring 442. The rotation limiting ring 444 is rotatably connected to the fixed shaft 443. Torsion springs 445 are connected between the upper and lower ends of the fixed shaft 443 and the rotation limiting ring 444.

[0030] In use, medical staff first move the device to the operating room. Then, they select a suitable measuring cylinder 22 according to the patient's body shape and place it in the middle of the top of the mounting block 21. Subsequently, the medical staff activates the electric push rod 32 through the control panel 35. The telescopic rod of the electric push rod 32 extends, pushing the pressing plate 33 downward. The pressing plate 33 presses against the top of the measuring cylinder 22 through the rubber plate 34, sealing the top of the measuring cylinder 22. After that, the medical staff makes a small incision in the patient's abdominal wall. Then, the medical staff holds the holding column 42 and takes out the tubing a and tubing b wrapped around the bracket 411 to a sufficient length for use. Then, the liposuction cannula 43 is inserted into the abdominal wall fat through the small incision. Finally, the water pump b61 is activated through the control panel 35. Pump b61 draws tumescent fluid from reservoir b63 via supply tube 62, pumps it into tubing b67 via injection tube 64 and connecting tube b65, and then through tubing b67 and branch tube 651 into the lumen b66 of liposuction cannula 43. Finally, it is injected into the patient's abdominal wall fat through outlet 661. This causes the abdominal wall fat to swell and fat cells to separate, facilitating subsequent suction. Compared to using a syringe, this method is more convenient. After injecting the tumescent fluid, medical staff turn off pump b61 via control panel 35 and simultaneously start negative pressure pump 46. Negative pressure pump 46 draws air out of measuring cylinder 22 through negative pressure tube 47, providing a negative pressure environment for measuring cylinder 22. This creates negative pressure in tubing b67, allowing the patient's abdominal wall fat to be suctioned out through outlet 451. The liposuction tube 43 is drawn into the lumen a45, then through the tubing b67 and connecting tube a40, and stored in the measuring cylinder 22. After liposuction, medical staff turn off the negative pressure pump 46 via the control panel 35 and simultaneously control the telescopic rod of the electric push rod 32 to retract, closing the top of the measuring cylinder 22. At this point, the measuring cylinder 22 can be removed from the top of the mounting block 21 and the matching cap can be placed on it. Then, the medical staff rotates the limiting ring 444 open, at which point the torsion spring 445 is tightened. The holding column 42 is then placed on the fixed limiting ring 442, and the rotating limiting ring 444 is released. Under the reset action of the torsion spring 445, the rotating limiting ring 444 automatically resets, clamping the holding column 42, so that the lower end of the liposuction tube 43 is located in the waste liquid tank 510. Then, the medical staff... Slide slider 53 to the rightmost side of track 52. Activate electric push rod 32 via control panel 35. The telescopic rod of electric push rod 32 extends, driving pressing plate 33 downwards. Connecting tube a40 moves downwards accordingly and inserts into receiving seat 55. Washer 56 seals the gap between the lower end of connecting tube a40 and receiving seat 55. Medical personnel then activate water pump a51 via control panel 35. Water pump a51 draws flushing fluid from storage tank a58 through outlet pipe 59, injects it into receiving seat 55 through flushing pipe 591 and riser pipe 54, and then injects it into tubing a41 from receiving seat 55. The flushing fluid passes through tubing a41 and liposuction cannula 43, finally flowing out from suction port 451 into waste liquid tank 510, backflushing tubing a41 and lumen a45.To avoid fat cells adhering to the tubing (a41) or lumen (a45) due to delayed cleaning, which would increase the difficulty of subsequent cleaning.

[0031] like Figure 6 and Figure 7 As shown, it also includes C-shaped blocks 71, connecting blocks 72, locking blocks 73, and bidirectional lead screws 74. Connecting blocks 72 are symmetrically slidably arranged on the mounting block 21. Locking blocks 73 are fixed to the upper part of the two connecting blocks 72 by bolts. Two C-shaped blocks 71 are welded and fixed to the outer walls of the front and rear sides of the measuring cylinder 22 in correspondence with the two locking blocks 73. Bidirectional lead screws 74 are rotatably connected between the front and rear side walls of the mounting block 21. The bidirectional lead screws 74 pass through the two connecting blocks 72 respectively and are threadedly engaged with both.

[0032] By setting up components such as C-shaped blocks 71 and connecting blocks 72, after the measuring cylinder 22 is placed in the middle of the top of the mounting block 21, medical staff can rotate the bidirectional screw 74. When the bidirectional screw 74 rotates, it pushes the two connecting blocks 72 to move closer to each other, causing the two locking blocks 73 to come together and clamp and cooperate with the two C-shaped blocks 71 set on the outer wall of the measuring cylinder 22, thereby clamping and fixing measuring cylinders 22 of different models, making the measuring cylinder 22 more stable during use.

[0033] like Figure 7 As shown, it also includes a screw 81, a motor 82 and an infrared sensor 83. The screw 81 is rotatably connected between the left and right sides of the track 52. The motor 82 is installed on the left side of the track 52 by bolts. The output shaft end of the motor 82 is fixedly connected to the left end of the screw 81. The infrared sensor 83 is embedded in the right side of the mounting block 21. The control panel 35 is electrically connected to the motor 82 and the infrared sensor 83.

[0034] By setting up a screw 81, a motor 82, and an infrared sensor 83, after the abdominal wall fat is aspirated, the medical staff removes the measuring cylinder 22. After the infrared sensor 83 detects that the measuring cylinder 22 has been removed, it sends a signal to the control panel 35. The control panel 35 then starts the motor 82 and the electric push rod 32 in sequence. The motor 82 drives the screw 81 to rotate, pushing the slider 53 to the rightmost side of the track 52. At this time, the telescopic rod of the electric push rod 32 extends, driving the connecting tube a40 to move downward and insert into the receiving seat 55. No manual operation is required from the medical staff, which saves more time and effort.

[0035] like Figure 1 and Figure 9As shown, it also includes slide rails 91, drawers 92 and L-shaped plates 93. Two slide rails 91 are welded and fixed at intervals on both the front and rear sides of the mobile trolley 1. Drawers 92 are slidably arranged between the two slide rails 91 at the same height. The bottom of the lower drawer 92 is in contact with the bottom plate of the mobile trolley 1. L-shaped plates 93 are fixedly connected to both the front and rear sides of the mobile trolley 1 near the top of the lower drawer 92. The L-shaped plates 93 are in contact with the bottom of the upper drawer 92.

[0036] By setting up slide rails 91, drawers 92 and L-shaped panels 93, medical staff can place medical equipment in the two drawers 92, which facilitates the storage and management of medical equipment.
