Indications for Use
The “HsingChi” LipoSelector Disposable Fat Collection System (LS-1200) is a sterile medical device intended for the processing of lipoaspirate tissue for the purpose of transferring autologous adipose tissue for aesthetic body contouring (lipofilling) in applications including plastic and reconstructive surgery, neurosurgery, gastrointestinal and affiliated organ surgery, urological surgery, general surgery, orthopedic surgery, gynecological surgery, thoracic surgery, and laparoscopic surgery. Only legally marketed accessory items, such as syringes, should be used with the system. If harvested fat is to be reimplanted, the harvested fat is only to be used without any additional manipulation.
Device Story
Closed-system disposable canister (1200cc) for processing lipoaspirate; used in healthcare facilities by trained medical staff. Device connects to external liposuction system via tubing; aspirates fat into canister. Internal filter basket (3.0mm) captures large tissue strands; 300μm mesh filter separates impurities (blood, broken fat) via bottom port. Decanting process (8-10 mins) separates tumescent fluid/water, drained through side port. Device does not contact patient directly. Output is processed autologous fat for immediate reimplantation without further manipulation. Disposable design eliminates cleaning/sterilization burden and reduces infection risk.
Clinical Evidence
No clinical data. Substantial equivalence supported by bench testing including biocompatibility (ISO 10993), EO sterilization validation (ISO 11135), package integrity (ASTM F1980, F1886, F1140, F88), and performance testing (fat filtration, container strength, chemical analysis).
Technological Characteristics
Closed-system canister (1200cc) made of PETG, HDPE, PP, and PC. Features double-filter design: 3.0mm filter basket and 300μm mesh filter. EO sterilized. Single-use. Vacuum-operated via external suction machine (max 900mbar).
Indications for Use
Indicated for patients undergoing autologous adipose tissue transfer for aesthetic body contouring in various surgical specialties including plastic, reconstructive, neuro, gastrointestinal, urological, general, orthopedic, gynecological, thoracic, and laparoscopic surgery.
Regulatory Classification

The device consists of a powered suction pump (containing a microbial filter on the exhaust and a microbial in-line filter in the connecting tubing between the collection bottle and the safety trap), collection bottle, cannula, and connecting tube. The microbial filters, tubing, collection bottle, and cannula must be capable of being changed between patients. The powered suction pump has a motor with a minimum of 1/3 horsepower, a variable vacuum range from 0 to 29.9 inches of mercury, vacuum control valves to regulate the vacuum with accompanying vacuum gauges, a single or double rotary vane (with or without oil), a single or double diaphragm, a single or double piston, and a safety trap.

## 6. Indications for use
The “HsingChi” LipoSelector Disposable Fat Collection System (LS-1200) is a sterile medical device intended for the processing of lipoaspirate tissue for the purpose of transferring autologous adipose tissue for aesthetic body contouring (lipofilling) in applications including plastic and reconstructive surgery, neurosurgery, gastrointestinal and affiliated organ surgery, urological surgery, general surgery, orthopedic surgery, gynecological surgery, thoracic surgery, and laparoscopic surgery. Only legally marketed accessory items, such as syringes, should be used with the system. If harvested fat is to be reimplanted, the harvested fat is only to be used without any additional manipulation.
## 7. Device description
The “HsingChi” LipoSelector Disposable Fat Collection System (hereafter LipoSelector) is designed for fat harvesting and filtering purpose.
The main structure of LipoSelector: Canister (1200c.c), filter basket, side port and filter mesh, it does not contact with the patient body directly.
LipoSelector is a completely closed system and undergoes ethylene oxide (EO) sterilization, ensuring that the entire liposuction process is free from contamination.
The function principle of LipoSelector in medical institutions typically involves the use a liposuction system to aspirated fat from a patient's body, which is then collected and processed in a canister. The filtration gap of the filter basket is 3.0 mm, larger tissue strands of the aspirate are caught in the filter basket. Turn off the suction machine when you stop the harvesting, then proceed with the decant procedure (around 8-10 mins) until tumescent and fat separation. The tumescent fluid and water are then drained through the side port. The 300 μm filter mesh is fine enough to effectively further separate impurities such as broken fat and blood through the bottom port.
Its disposable nature allows each patient to have their own LipoSelector, eliminating the risk of infection. This also spares nursing staff from the burden of cleaning and sterilizing the fat collection, simplifying the liposuction process.
