Description

Technical Field

[0001] The utility model relates to the technical field of plastic surgery and medical liposuction equipment, in particular to a plastic surgery and medical liposuction device which is convenient for adjusting the angle. Background Art

[0002] Liposuction refers to a method of reducing the number of fat cells by reaching into the subcutaneous fat layer through a skin incision, using different means to break up the fat, and sucking out excess fat particles from the body through negative pressure suction. It uses a negative pressure vacuum aspirator (0.5 to 1.0 atmospheres) connected to a metal suction tube with a suction hole at the end, enters the subcutaneous tissue through a small incision in the skin, and sucks out locally accumulated fat tissue to improve obese body shape. The liposuction needle is a component for sucking the subcutaneous fat layer, and its function is very critical. A good liposuction needle can reduce damage to patients and improve surgical efficiency.

[0003] The utility model relates to the technical field of plastic surgery and medical liposuction equipment, specifically a liposuction needle (CN212651139U). The utility model provides a liposuction needle, relates to the technical field of fat transplantation, and solves the problem of low efficiency and poor postoperative effect of liposuction needle surgery. The liposuction needle includes a needle body for connecting to the liposuction equipment, the needle head of the needle body is arc-shaped, and a plurality of suction holes are distributed on the needle body, and the plurality of suction holes are located on the periphery of the needle body and are distributed in a spiral shape. The liposuction needle of the utility model has an arc-shaped needle head that is not easy to damage fat cells, and the damage is small, and the plurality of spirally distributed suction holes can increase the amount of fat in a unit time to 3-4 times, the shorter the operation time, the higher the operation efficiency, the shorter the operation time for the same amount of fat suction in the same part, and the treatment area is not limited during each treatment, which is beneficial to the postoperative recovery of the patient. However, during use, since there is a layer of subcutaneous tissue on the upper surface of the human body's fat layer, in order to reduce damage to the subcutaneous tissue, multiple liposuction needles of different sizes and multiple liposuction holes in different positions are generally provided during liposuction surgery. By replacing them according to the different depths of the liposuction site, when liposuction is performed on the fat layer close to the subcutaneous tissue, the negative pressure needle hole contacts the subcutaneous tissue, causing damage to the subcutaneous tissue. The needle replacement operation reduces the efficiency of the operation, which brings certain troubles to the physician. For this reason, we propose a plastic surgery and medical liposuction device that is easy to adjust the angle. Utility Model Content
