Description

Technical Field

[0001] The utility model relates to the technical field of liposuction equipment, in particular to a syringe with a liposuction incision protection device. Background Art

[0002] In modern liposuction surgery, based on vacuum negative pressure liposuction, instrument assistance (ultrasonic emulsification technology, power-assisted liposuction technology) has emerged. When the fat is quickly mechanically pulled out, the liposuction needle rubs against the incision for a long time, causing damage to the skin edge; at the same time, energy-type auxiliary instruments may also cause burns to the skin, resulting in poor incision healing, scar hyperplasia, and affecting the appearance. Therefore, a protective structure needs to be set to protect the incision. Most skin incision protectors on the existing market are made of silicone and are relatively expensive. Although they can be repeatedly disinfected and reused, they are easily damaged during use due to suture cutting or repeated high-temperature disinfection, and may also cause cross infection. Therefore, there is an urgent need for a skin incision protector that is simple in structure, easy to use, economical and environmentally friendly. Utility Model Content

[0003] The utility model aims at the shortcomings of the prior art and provides a syringe with a liposuction incision protection device.

[0004] In order to solve the above technical problems, the present invention is solved by the following technical solutions:

[0005] A syringe with a liposuction incision protection device includes a protective tube with two ends open, the upper end of the protective tube is provided with a wing plate extending outward, the wing plate is provided with a threading hole, and the threading hole is equipped with a suture for fixing the skin; the lower end of the protective tube is provided with an external thread, and also includes a needle tube, one end of the needle tube is provided with an internal thread, and the protective tube is installed on the needle tube through the cooperation of the external thread and the internal thread. At this time, the protective tube and the needle tube are coaxially arranged to form a complete tube body, and also includes a piston rod that is sealed with the tube walls of the protective tube and the needle tube. The piston rod cooperates with the needle tube and can be pushed in a sealing manner on the inner wall of the needle tube, and can also be sealed with the inner wall of the protective tube alone.

[0006] Preferably, there are at least two wing plates, which are symmetrically distributed on the protective tube.

[0007] Preferably, the lower surface of the wing plate is provided with a silicone pad that fits the skin.

[0008] Preferably, the outer side of the wing plate is a smooth arc-shaped edge.

[0009] Preferably, a needle seat is provided at one end of the needle tube, and a connecting seat integrally formed with the needle tube is provided on the other end of the needle tube. The connecting seat is a tube sleeve that protrudes outward and has an inner diameter larger than the inner diameter of the needle tube. The internal thread is provided on the inner wall of the connecting seat, and the lower end of the protective tube is fixedly connected to the connecting seat thread through its external thread.

[0010] Preferably, the inner diameter of the protective tube is the same as the inner diameter of the needle tube, so that the piston rod can fit on the inner wall of the assembled tube.

[0011] Preferably, the inner diameter of the needle tube is 3.5 to 4.5 mm.

[0012] Preferably, the protective tube is provided with a plurality of liposuction needle grooves, which are circumferentially distributed on the inner wall of the upper end of the protective tube. The groove surface of the liposuction needle groove is arc-shaped and cooperates with the needle wall of the liposuction needle, so that the doctor can insert the liposuction needle obliquely along the liposuction groove in turn to perform liposuction on the opposite side during liposuction, making the surgical effect more uniform and improving the success rate.

[0013] Due to the adoption of the above technical solutions, the present invention has significant technical effects: while realizing the function of protecting the incision, the present invention can also cooperate with the needle tube to form a syringe. The disposable design can avoid the repeated high-temperature disinfection in the existing technology that causes the product to be easily damaged, and can also avoid cross infection, effectively realizing dual use of one product, and is suitable for a variety of medical needs.
