Description

Knee joint effusion extraction instrument and operation method Technical Field The application belongs to the technical field of effusion extraction devices, and particularly relates to a knee joint effusion extraction instrument and an operation method. Background Knee joint effusion is a common disorder in the fields of orthopedics and sports medicine, and seriously affects the quality of life of patients. About 15% of osteoarthritis patients worldwide are statistically accompanied by moderately severe knee joint effusions, and more than 200 tens of thousands of cases of knee joint effusion are annually caused by sports injury in our country. Traditional arthroscopic aspiration is the current routine means of clinically treating knee joint effusion, but this technique has a number of drawbacks. During operation, the penetration is entirely dependent on the physician's experience, and the lack of standardized aids results in a significant increase in the risk of secondary injury or infection to the soft tissue. The existing anesthesia mode mainly comprises local injection, so that not only is the wound of a patient increased, but also the pain relieving effect is limited, and the pain of the patient is obvious in operation. Traditional knee joint effusion extraction puncture operation lacks intelligent assistance, and has extremely high degree of dependence on personal experience of doctors in the actual operation process. Because of the lack of standardized auxiliary tools, doctors need to judge key operation parameters such as puncture angle, puncture depth, puncture strength and the like by virtue of experience accumulated by the doctors during puncture. This not only increases the difficulty of the procedure, but also can cause serious complications such as secondary injury or infection of soft tissues as soon as the doctor has a slight deviation in the procedure. Disclosure of Invention In order to solve the problems, the application provides a knee joint effusion extractor which has the effects of facilitating puncture operation and ensuring puncture efficiency and puncture safety, and comprises an auxiliary piece and a main piece, wherein the auxiliary piece is configured to connect the main piece with a knee joint, and is connected with a traditional Chinese medicine patch; The main body part comprises a shell, an extraction channel is formed in the shell, a limiting part is arranged in the extraction channel, and the limiting part limits the moving position of the extraction part. The limiting piece comprises a limiting ring and an elastic piece, one end of the elastic piece is connected with the inner wall of the extraction channel, the other end of the elastic piece is connected with the limiting ring, and the diameter of the limiting ring is smaller than that of the needle cylinder in the extraction piece. Further, the limiting piece further comprises a clamping ring, the clamping ring is arranged on the outer wall of the shell, the clamping ring is connected with a flexible rope, and the other end of the flexible rope is connected with the limiting ring. Further, a plurality of clamping grooves are formed in the outer wall of the shell, and the clamping rings are matched with the clamping grooves. Further, the traditional Chinese medicine patch comprises a back lining material, a medicine penetrating hole is formed in the middle of the traditional Chinese medicine patch, a medicine patch matrix is attached to the back lining material, the auxiliary piece is matched with the back lining material to wrap the medicine patch matrix, and the auxiliary piece is fixed to the knee joint. Further, the patch matrix comprises Olibanum, myrrha, flos Daturae Metelis, rhizoma Ligustici Chuanxiong, carthami flos, borneolum Syntheticum, and transdermal liquid. Further, the auxiliary piece is prefabricated into an arc matched with the knee joint, and the main body piece is integrated with a monitoring component. Further, the preparation method of the traditional Chinese medicine patch comprises the following steps: mixing Olibanum, myrrha, flos Daturae Metelis, rhizoma Ligustici Chuanxiong, and Carthami flos at a certain proportion, pulverizing to obtain pulverized mixture; reflux extracting the filtrate with hot water bath, concentrating the filtrate under reduced pressure to relative density to obtain Chinese medicinal extract; Adding Borneolum Syntheticum fine powder and transdermal liquid into the Chinese medicinal extract, stirring, and making into paste; Compounding the adhesive, the humectant and the paste to obtain a plaster matrix, coating the plaster matrix on a backing material, drying, and covering a laminating layer to form a traditional Chinese medicine plaster; And punching a medicine penetration hole formed in the center of the traditional Chinese medicine patch, wherein the medicine penetration hole corresponds to the knee joint puncture point area.
