Description

Technical Field

[0001] This utility model belongs to the field of liposuction technology, specifically, it relates to a hydraulic separation head device for liposuction. Background Technology

[0002] The process of hydrodynamic separation of fat cells involves the following steps: Before the surgery begins, a tumescent solution is injected into the liposuction area. The main components of this solution include local anesthetics and vasoconstrictors, such as lidocaine and epinephrine. Lidocaine provides anesthesia, reducing patient pain; epinephrine constricts blood vessels, reducing intraoperative bleeding. After the tumescent solution is injected, the fat tissue gradually expands and separates, increasing the spaces between fat cells and making the structure relatively loose, thus facilitating hydrodynamic separation and creating favorable conditions for subsequent fat aspiration. After the fat cells are separated by hydrodynamic force, a vacuum liposuction device connected to a suction cannula generates negative pressure to suction the separated fat tissue out of the body. The negative pressure can be adjusted according to the surgical situation, generally between -400 mmHg and 700 mmHg, to quickly and effectively aspirate the liquefied fat tissue. Water-assisted liposuction employs a simultaneous fat decomposition and removal mechanism, seamlessly integrating fat separation and removal. This significantly improves efficiency, shortens surgery time, and makes the entire process smoother and faster. The extracted fat tissue, along with tumescent fluid and rinsing solution, is drained through a suction cannula. These fat cells, due to minimal damage, exhibit good activity and high purity. After filtration and separation, they can be used for autologous fat grafting procedures such as breast augmentation and buttock augmentation, improving fat utilization. Because water-assisted liposuction causes minimal damage to surrounding tissues, patients experience less postoperative pain, bleeding, and swelling. The incidence of complications such as uneven skin texture is also lower, and wounds heal quickly, typically within one month. Furthermore, the fat is less likely to rebound, maintaining a good shaping effect long-term.

[0003] Existing separation head devices have low separation efficiency, and the fat particles extracted by the liposuction cannula are of uneven size. Utility Model Content

[0004] In view of this, the present invention provides a hydraulic separation head device for liposuction, which can solve the problems of low separation efficiency and uneven size of fat particles extracted by the liposuction cannula in existing separation head devices.

[0005] This utility model is implemented as follows:

[0006] This utility model provides a liposuction hydraulic separation head device, comprising a shell, a hydraulic chamber, a separation layer, a suction tube opening, and a drive assembly. The shell is a streamlined elliptical body containing the hydraulic chamber. One end of the hydraulic chamber is connected to a liposuction tube, and the sidewall of the liposuction tube is connected to the drive assembly. The shape of the hydraulic chamber conforms to the internal space of the shell to provide a negative pressure environment. The separation layer is connected to the hydraulic chamber and is a porous mesh located at the front end of the hydraulic chamber for filtering and separating fat cells. The suction tube opening is connected to the separation layer and is a porous cone shape.

[0007] The technical advantages of the liposuction hydraulic separation head device provided by this utility model are as follows: By setting the shell into a streamlined elliptical structure, not only is the aesthetics and operational comfort of the device enhanced, but its flexibility and controllability during surgery are also optimized. The streamlined design helps reduce unnecessary resistance during surgery, allowing the device to move more smoothly and reducing the burden on the physician during operation. The internal space design of the shell matches the hydraulic chamber, ensuring the stable operation of the hydraulic device.

[0008] In this design, the hydraulic chamber serves as the hydraulic drive. Connected to the drive assembly, the hydraulic chamber contains and pressurizes a liquid used to separate fat cells. The function of the hydraulic chamber is to transmit hydraulic pressure to the front-end separation layer, ensuring pressure control during the separation process and thus achieving effective separation of fat cells.

[0009] Based on the above technical solution, the liposuction hydraulic separation head device of this utility model can be further improved as follows:

[0010] The driving component is a hydraulic pump, which is connected to the liposuction tube and is used to provide hydraulic pressure.

[0011] The beneficial effects of adopting the above-mentioned improved scheme are as follows: the drive component uses a hydraulic pump, which is connected to the hydraulic chamber and provides the required hydraulic pressure. This design ensures precise control of liquid pressurization, making the fat separation process more efficient and controllable. The addition of the hydraulic pump improves operational stability and effectiveness, and allows for adjustment of hydraulic pressure according to different fat densities, thereby effectively separating fat.

[0012] Furthermore, the separation layer comprises multiple layers of titanium alloy mesh with progressively smaller pore sizes, used for graded separation based on the size of fat particles, thereby improving the purity and quality of the fat.

[0013] The beneficial effects of the above-mentioned improved scheme are as follows: The separation layer, located at the front end of the hydraulic chamber, is a porous screen-like structure. Its design purpose is to filter and separate fat cells, ensuring the purity of the fat. Through screen layers with different pore sizes, fat particles of different sizes can be effectively separated, improving the quality of the fat. In a further improvement, the separation layer uses multi-layer titanium alloy screens with progressively smaller pore sizes, making the grading and separation of fat particles even more refined, further improving the purity and quality of the fat.

[0014] Furthermore, a filter screen is installed inside the suction tube to prevent tissue fragments from entering the hydraulic cavity, thereby further improving surgical safety.

[0015] The beneficial effects of the above-mentioned improvement are as follows: The suction cannula, connected to the separation layer, is shaped like a porous cone. This design helps to better aggregate the separated fat cells, allowing for collection and removal of this fat through the cannula. The cone-shaped structure helps to concentrate the fat, thereby improving liposuction efficiency. A filter is also installed inside the suction cannula; this improvement effectively prevents larger tissue fragments from entering the hydraulic cavity, ensuring safety during the procedure and reducing postoperative complications.

[0016] Furthermore, a vibrator is provided on the side wall where the separation layer connects to the hydraulic cavity. The vibrator is a piezoelectric ceramic used to generate high-frequency vibrations, effectively dispersing fat cells and making them easier to pass through the separation layer, thereby improving separation efficiency.

[0017] The beneficial effects of the above-mentioned improvement scheme are as follows: To further improve the efficiency of fat separation, a vibrator made of piezoelectric ceramic material is installed at the connection sidewall of the separation layer. By generating high-frequency vibration, the vibrator can effectively disperse fat cells and prevent them from agglomerating. The vibration makes it easier for fat cells to pass through the porous separation layer, thereby improving the separation efficiency and making it easier to separate fat cells.

[0018] Furthermore, an insulation layer is provided on the inner wall of the shell to maintain the temperature inside the suction tube, prevent fat from solidifying, and improve the fluidity of the fat.

[0019] The beneficial effects of the above-mentioned improvement scheme are as follows: The heat insulation layer on the inner wall of the shell is used to maintain the temperature inside the suction cannula, preventing fat from solidifying due to low temperature during the suction process. Maintaining a certain temperature can keep the fat in a liquid or semi-fluid state, increasing its fluidity and further improving liposuction efficiency. The heat insulation layer helps to ensure the state and fluidity of the fat during the operation, avoiding fat blockage of the liposuction cannula due to excessively low temperature.

[0020] Furthermore, the liposuction cannula is a silicone tube.

[0021] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the liposuction cannula is designed as a silicone tube, a material with good flexibility and durability, which can adapt to complex surgical environments. The softness of the silicone tube makes it easier to adjust and manipulate during surgery, reducing patient discomfort.

[0022] Furthermore, the front end of the shell is provided with a transparent layer window to facilitate intraoperative observation of fat separation.

[0023] The beneficial effects of adopting the above-mentioned improved design are as follows: the front end of the shell is equipped with a transparent layer window, providing a visual perspective that allows the surgeon to observe the fat separation effect in real time during the operation. This design enables the surgeon to more accurately judge the progress of the operation and adjust the surgical plan in a timely manner.

[0024] Furthermore, a pressure sensor is installed inside the housing. The pressure sensor is a miniature silicon piezoresistive sensor used to monitor changes in pressure inside the cavity in real time.

[0025] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: a miniature silicon piezoresistive sensor is installed inside the housing to monitor the pressure changes in the hydraulic chamber in real time. By monitoring the pressure, doctors can ensure that the pressure during the hydraulic separation process remains within a safe range, thereby avoiding improper surgery or increased risks due to excessively high or low pressure.

[0026] Furthermore, the end of the liposuction cannula is connected to a collection bag for collecting the separated fat.

[0027] The beneficial effects of adopting the above-mentioned improved solution are as follows: a collection bag is connected to the end of the liposuction cannula to collect the separated fat. The collection bag design effectively ensures that the separated fat can be safely stored and facilitates subsequent processing or storage, avoiding fat spillage or contamination.

[0028] Compared with the prior art, the beneficial effects of the liposuction hydraulic separation head device provided by this utility model are:

[0029] The streamlined elliptical structure of the housing enhances both the aesthetics and operational comfort of the device, while also optimizing its flexibility during surgery. This design helps reduce resistance during operation, making the device easier to move, alleviating the surgeon's workload, and improving overall control performance.

[0030] The hydraulic chamber plays a crucial role in the equipment. By providing a negative pressure environment, the hydraulic chamber helps to precisely control the pressurization of the fluid, thereby achieving effective separation of fat cells. The shape of the hydraulic chamber conforms to the internal space of the housing, ensuring stable operation of the equipment and providing the necessary power support for fat cell separation.

[0031] The hydraulic pump connects to the liposuction cannula, precisely controlling the hydraulic pressure to ensure efficient separation of fat cells. The stable pressure provided by the hydraulic pump can be adjusted according to different fat densities, improving the controllability and efficiency of the procedure.

[0032] The separation layer utilizes a multi-layered titanium alloy mesh to achieve graded separation of fat particles, with the pore size decreasing layer by layer, effectively filtering according to the size of the fat particles. This design improves the purity and quality of the fat, ensuring that the separated fat meets higher standards during surgery.

[0033] The porous, tapered design of the suction cannula helps concentrate fat cells, making the liposuction process more efficient. The tapered structure helps improve fat collection efficiency, and the internal filter effectively prevents larger tissue fragments from entering the hydraulic chamber, improving surgical safety.

[0034] By incorporating piezoelectric ceramic vibrators on the sidewalls of the separation layer, high-frequency vibrations can be generated, further improving the dispersion of adipocytes and preventing their aggregation. Vibration helps adipocytes pass through the sieve more easily, increasing separation efficiency and ensuring effective separation of adipocytes.

[0035] The inner wall of the casing is insulated to maintain the temperature inside the suction cannula, preventing fat from solidifying due to low temperatures during extraction. Appropriate temperature helps maintain fat fluidity, avoiding cannula blockage caused by fat solidification, thereby improving surgical efficiency.

[0036] The flexibility and durability of silicone tubing make it suitable for complex surgical environments. Its softness facilitates manipulation and reduces patient discomfort, while the durability of the silicone material ensures stability during the surgical procedure.

[0037] The transparent window at the front of the casing provides a visual observation view, allowing doctors to monitor the fat separation process in real time during surgery. This design enables doctors to more accurately judge the progress of the surgery and make timely adjustments.

[0038] A pressure sensor monitors pressure changes in the hydraulic chamber in real time, ensuring that the pressure remains within a safe range. This design effectively avoids surgical risks caused by excessively high or low pressure, ensuring the precision and safety of the surgery.

[0039] The liposuction cannula connects to a collection bag at the end, effectively collecting the separated fat and ensuring its safe storage, preventing spillage or contamination. This design facilitates subsequent fat processing and storage, while also improving the overall safety of the procedure. Attached Figure Description
