Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a foldable and lifting saline support for perfusion under bone arthroscopy. Background Art

[0002] Arthroscopy is a commonly used instrument for minimally invasive orthopedic surgery. During knee arthroscopy, the joint cavity needs to be filled with saline to improve the field of view of the joint cavity.

[0003] Joint perfusion and expansion are necessary during the entire arthroscopic procedure; proper expansion can push away synovial folds and other soft tissues within the field of view, expand the volume within the joint, and improve the operability of the arthroscope;

[0004] Perfusion can be divided into air and liquid. Air has good imaging effect and fast joint expansion. However, gas is more likely to overflow and cause joint collapse, and bubbles in the joint affect observation. There is a possibility of subcutaneous emphysema and gas venous embolism, so it is rarely used. Liquids must be sterile, non-irritating to synovial fluid, have good visibility, be able to perform basic operations in it, and have no systemic and local side effects. Physiological saline or lactated Ringer's solution are commonly used. Perfusion can be directly inserted through the arthroscopic sheath or through the suprapatellar bursa using a separate inlet.

[0005] High-position perfusion requires placing the fluid bag at a height of more than one meter above the joint plane; if a pressure perfusion system is used, the expansion pressure of the knee joint is between 60 and 80 mmHg.

[0006] In summary, the following technical problems exist in the working process of the current arthroscopic perfusion system: 1) During arthroscopic surgery, the joint cavity is filled with the perfusion system to improve the field of view of the joint cavity and help the doctor to have a clear field of view. Water will be absorbed by the synovial tissue and leak out from the gaps during the operation of the surgical instruments, causing the liquid level in the liquid bag to drop. The liquid loss is accompanied by the deformation of the liquid bag. The liquid level drop and time change do not always maintain a linear relationship. The length of the liquid bag accounts for about one-tenth of the distance between the liquid surface and the joint plane. The perfusion pressure in the joint cavity drops significantly as the liquid level drops, which has a great impact on the perfusion pressure adjusted before the operation, making the effect of medical staff increasing the perfusion pressure to stop bleeding due to patient bleeding ineffective; 2) Because a surgery requires For two liquid bags of about 2L, the existing flushing tower has a lot of problems in controlling the height. Medical staff reported that the operation was tiring, and the hydraulic device was expensive and rarely equipped in hospitals, resulting in a waste of medical staff's physical strength in adjusting the height of the liquid bag during surgery, hindering the progress of the operation; 3) Existing perfusion equipment such as infusion stands are not easy to carry when medical staff go to other hospitals for treatment, which affects the doctors' surgical operating habits, causes interference with the operation, and is not conducive to the promotion of perfusion equipment; 4) Medical staff reported that the space in the operating room is limited, and anesthesiologists, nurses and other medical staff will touch the perfusion equipment, which will cause the liquid bags on the perfusion equipment to be dangerous, and also cause stumbling and danger to medical staff, and the disc-shaped base takes up a lot of space and is not easy to store.
