Description

Technical Field

[0001] This utility model relates to the field of medical device manufacturing technology, and in particular to a cryolipolysis tablet handle. Background Art

[0002] Cryolipolysis, a novel non-invasive surgical fat reduction method, utilizes the principle that fat cells are more easily cooled than other skin cells. The precise application of cryolipolysis triggers apoptosis in fat cells, and the resulting inflammatory response leads to the slow digestion of fat cells by surrounding macrophages. Due to its safety and reliability, it has been highly sought after by many beauty enthusiasts since its introduction. Cryolipolysis devices mainly consist of a cryolipolysis main unit and a cryolipolysis handpiece. As the machine that comes into direct contact with the body, the cryolipolysis handpiece uses negative pressure to draw fat from the skin into its inner cavity. This treatment typically takes 50 minutes to an hour. Prolonged exposure to negative pressure can damage the skin, causing congestion or bruising, and even blisters; in more severe cases, skin infection may occur. Furthermore, traditional cryolipolysis handpieces are concave, encasing the skin inside, resulting in uneven cooling. This can lead to poor treatment results in certain areas, and in some cases, frostbite. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model discloses a cryolipolysis flat plate handle.

[0004] The specific technical solution is as follows:

[0005] A cryolipolysis flat plate handle includes a lower shell, an upper shell, a cryo-copper plate, a thermoelectric cooling chip, a heat sink, and a pair of pull rings. The lower shell and the upper shell are connected by a snap fastener, and a positioning groove is formed on the lower shell. The cryo-copper plate is square with countersunk holes at its four corners. The cryo-copper plate is fixed to the positioning groove by screws. One side of the cryo-copper plate is flat and contacts the treatment area. A limiting groove is formed in the middle of the other side of the cryo-copper plate, and the thermoelectric cooling chip is embedded in the limiting groove. The hot end of the thermoelectric cooling chip directly contacts the heat sink, and the heat sink is connected to external cooling water through a water pipe. The thermoelectric cooling chip and the heat sink are fixed by a fixing assembly. The pair of pull rings are installed one in front of the other between the lower shell and the upper shell and can rotate at a certain angle.

[0006] The fixing components include a fixing frame and a limiting frame, which restrict movement from the left and right and front and back directions, respectively.

[0007] The fixing bracket is installed on the lower housing. Each side of the fixing bracket has a downwardly extending limiting platform to limit the lateral displacement of the thermoelectric cooler and the heat sink. The fixing bracket has a threaded hole B, and the lower housing has a corresponding threaded hole A. The thermoelectric cooler and the heat sink are fixed by connecting the threaded holes A and B with screws.

[0008] The limiting bracket is mounted on the upper housing, and each of the front and rear sides of the limiting bracket has a downwardly extending protrusion to limit the front and rear displacement of the semiconductor cooling chip and the heat sink.

[0009] Male buckles are provided on the upper perimeter of the lower housing, and female buckles are provided on the lower perimeter of the upper housing. The male buckle is a cantilever buckle, with an inlet angle of 30° formed by the inlet surface and the vertical direction, and an outlet angle of 90° formed by the outlet surface and the vertical direction. The male and female buckles are connected by a clasp.

[0010] The lower and upper housings each have a semi-circular lower groove and an upper groove at the front and back, respectively. When the lower and upper grooves are engaged, they form a circular hole. The pull ring is installed in the circular hole, and the axis of the circular hole overlaps with the radial axis of the pull ring.

[0011] A cable inlet is provided on the rear side of the upper housing to allow water pipes and wires to enter the handle cavity.

[0012] There is a ramp at the rear of the lower casing, which guides the connection between the water pipes and the radiator.

The freezing copper plate 3 is fixed to the positioning groove 13 by screws. One side of the freezing copper plate 3 is flat and contacts the treatment area. Because it is flat, the entire copper plate has a uniform cooling area and is less likely to cause frostbite when in contact with the human body. A limiting groove 32 is provided in the middle of the other side of the freezing copper plate 3. The semiconductor cooling chip 4 is embedded in the limiting groove 32 to restrict the semiconductor cooling chip from sliding in all directions; the hot end of the semiconductor cooling chip 4 directly contacts the heat sink 5 to ensure heat dissipation efficiency. The heat sink 5 is connected to external cooling water through water pipes; the semiconductor cooling chip 4 and the heat sink 5 are fixed by a fixing component; the fixing component includes a fixing frame 6 and a limiting frame 21, which restrict the movement from the left and right and front and back directions, respectively. The fixing frame 6 is set on the lower housing 1. The fixing frame 6 has a downwardly extending limiting platform 61 on each of its left and right sides to limit the left and right displacement of the semiconductor cooling chip 4 and the heat sink 5. The fixing frame 6 has a threaded hole B62, and the lower housing 1 has a corresponding threaded hole A14. The semiconductor cooling chip 4 and the heat sink 5 are fixed by connecting the threaded hole A14 and the threaded hole B62 with screws.

[0026] The limiting bracket 21 is mounted on the upper housing 2. The limiting bracket 21 has a downwardly extending protrusion on each of its front and rear sides to limit the front and rear displacement of the semiconductor cooling chip 4 and the heat sink 5.

[0027] The pair of pull rings 7 are installed one in front of the other between the lower housing 1 and the upper housing 2, and can be rotated at a certain angle for easy fixation during human treatment.

[0028] The lower housing 1 and the upper housing 2 each have a semi-circular lower groove 22 and an upper groove 11 at the front and rear, respectively. When the lower groove 22 and the upper groove 11 are engaged, they form a circular hole.
