Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of beauty plastic surgery, and particularly relates to a liposuction device suitable for the face. Background Technique
[0002] Facial liposuction is to insert a liposuction tube into the subcutaneous fat layer through a small incision in the skin, and use the suction force of negative pressure to suck the accumulated fat on the face out of the body, reshape the facial line, and achieve the purpose of improving the face shape. The liposuction needle is basically a slender steel needle. When liposuction is performed on the cheek, the liposuction needle needs to be inserted obliquely from the position under the ear and go straight into the lower jaw. During the operation, in order to break the fat and suck the fat evenly, the doctor needs to quickly and repeatedly insert and withdraw the liposuction needle under the skin.
[0003] At present, the relatively traditional facial fat reduction auxiliary device is manual liposuction, that is, the liposuction needle is directly connected to the syringe. During the operation, the doctor manually sucks the fat into the syringe through the liposuction needle while quickly moving the liposuction needle to achieve the purpose of liposuction. There is also a more advanced method, which is to connect the liposuction needle to a negative pressure system, so that the doctor only needs to quickly pull and push the liposuction needle under the skin to achieve the purpose of liposuction. However, due to the need to quickly and repeatedly insert and withdraw during the operation, the liposuction needle left under the skin will be hindered by the subcutaneous fat tissue during the movement. Moreover, the subcutaneous fat distribution is not strictly linearly and evenly distributed, and the doctor cannot guarantee to move linearly during the rapid insertion and withdrawal of the liposuction needle. Therefore, the liposuction needle may pick up or even circumferentially pick at the skin incision position, which will increase the risk of enlarging the incision wound surface. A larger wound surface will leave a larger scar during the later recovery process.
[0004] Therefore, as the facial multi-functional liposuction needle proposed in the patent with the publication number of CN213219727U, by setting the liposuction holes below the grooves on the side wall of the needle body, the head of the needle body is ellipsoidal to reduce the damage caused by liposuction, and a negative pressure device is used to directly suck the fat. However, it still requires an experienced doctor to operate so that the needle body can accurately insert and withdraw in the fat layer to fully emulsify the fat for easy extraction. For doctors with insufficient experience, if the insertion and withdrawal force is too large or too small, it is easy to stab the needle body out of the fat layer and cause damage to the body or skin. Content of the Utility Model
[0005] The purpose of the utility model is to provide a liposuction device suitable for the face to solve the technical problem that the existing facial fat extraction device is prone to poor force control during the insertion and withdrawal process, resulting in damage to the body or skin.
[0006] The embodiments of the utility model are realized through the following technical solutions:
[0007] A liposuction device suitable for the face comprises a negative pressure syringe for providing negative pressure and a liposuction needle connected to the negative pressure syringe, the side wall of the liposuction needle is provided with a liposuction hole for extracting fat, the liposuction needle is also provided with a soft connecting part connected to the negative pressure syringe and an ellipsoid part provided on the needle head, and an axially sliding pull rod is also provided inside the liposuction needle; one end of the pull rod is connected to the needle head of the liposuction needle through a first elastic member, and the other end is slidably connected to the connecting part.
[0008] Preferably, the pull rod is provided with a control ring slidably connected to the connecting portion.
[0009] Preferably, the control ring is provided with a connecting rod connected to the pull rod, the connecting portion is provided with a hole groove for passing the connecting rod, and the control ring is further provided with a sealing member for sealing the hole groove.
[0010] Preferably, the negative pressure syringe comprises a protruding connector connected to the connecting portion and a piston for creating negative pressure.
[0011] Preferably, the negative pressure syringe also includes a push ring slidably arranged on the outer periphery of the connecting head for pushing the control ring, and the push ring is also provided with a second elastic member for rebounding.
[0012] Preferably, the push ring is provided with a contact ring which passes through the negative pressure syringe and is pushed by the piston.
[0013] Preferably, the contact ring is provided with a sealing ring for sealing the portion passing through the negative pressure syringe.
[0014] Preferably, a push rod for controlling the piston is provided on the back side of the piston.
[0015] Preferably, the pull rod is provided with a plurality of groups of shifting plates for shifting fat in the liposuction hole.
[0016] By adopting this technical solution, the pull rod can be connected to the liposuction needle by sliding forward and backward, providing a certain buffering effect for the liposuction needle to be drawn;
[0017] Specifically, when in use, the liposuction needle is connected to the negative pressure syringe through the soft connection part. When extracting fat from the patient's fat layer, during the insertion process of the liposuction needle, the ellipsoid part reduces tissue damage and receives tissue resistance. The ellipsoid part is connected to the pull rod through the built-in first elastic member. The pull rod is not subject to tissue resistance. Due to the inward pumping and the action of the finger connection part, the pushing action of the negative pressure syringe is transmitted to the pull rod through the push ring, the first elastic member contracts, and the paddle on the pull rod is located at the top of the liposuction hole.
[0018] Then, during the outward pumping process, the negative pressure syringe first drives the pull rod outward. The pull rod drives the lever to move downward relative to the liposuction hole, which is convenient for driving the fat to cooperate with the extraction and can prevent the unemulsified fat from blocking the liposuction hole. The back-and-forth movement of the pull rod in the liposuction needle can also loosen the fat and prevent it from being blocked easily.
[0019] The technical solution of the embodiment of the present utility model has at least the following advantages and beneficial effects:
[0020] 1. In the present utility model, the pull rod is slidably connected to the liposuction needle back and forth, providing a certain buffering effect for the pumping of the liposuction needle;
[0021] 2. In the present utility model, the lever moves downward relative to the liposuction hole, which is convenient for driving the fat to cooperate with the extraction and can prevent the unemulsified fat from blocking the liposuction hole. The back-and-forth movement of the pull rod in the liposuction needle can also loosen the fat and prevent it from being blocked easily. Description of the Drawings
