Medical orthopaedic clinical free body extractor

Abstract

The invention relates to the technical field of medical auxiliary equipment, in particular to a medical orthopedic clinical free body extractor. The medical orthopedic clinical free body extractor comprises a puncture sleeve, a puncture tip is arranged at the bottom end of the puncture sleeve, and an elastic sleeve is connected to the outer side wall of the puncture sleeve; a lubricating cavity is formed between the elastic sleeve and the puncture sleeve, lubricating holes are circumferentially formed in the outer side wall of the lubricating cavity, and left-right symmetrical limiting plates are connected to the top end of the outer side wall of the puncture sleeve; a connecting pipe is inserted into an inner cavity of the puncture sleeve, a soft pipe communicates with the bottom end of the connecting pipe, an elastic cover with the bottom end in an external expansion shape communicates with the bottom end of the soft pipe, anti-blocking semi-rings which are symmetrical left and right are embedded in the inner side wall of the bottom end of the elastic cover, and the anti-blocking semi-rings are connected through buffer springs at the ends of the anti-blocking semi-rings; and a negative pressure mechanism communicates with the top end of the connecting pipe. The medical orthopaedic clinical free body extractor is reasonable in structural design and high in practicability, and has an excellent market popularization value.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to a medical orthopedic clinical loose body extractor. Background technique [0002] Loose bodies are also called joint rats. In joints such as knees or elbows, the convex surface of certain pressure epiphyses can undergo ischemic necrosis and exfoliation under repeated external forces, and they are free in the joints, which is called osteochondritis dissecans (joint dissociation) body). In addition, synovial metaplasia on the free body can form chondrocytes or bone cells to continue to grow. Moreover, the loose bodies of the knee joint often appear joint locking phenomenon, and because the smaller loose bodies are squeezed between the articular surfaces, sudden joint locking phenomenon occurs. When it occurs, the patient will have severe pain, and the locked position is often not fixed. Patients may experience joint swelling, effusion, knee weakness due to me...

Problems solved by technology

[0005] Aiming at the above-mentioned shortcomings existing in the prior art, the present invention provides a medical orthopedic clinical loose body extractor, which can effectively solve the problem that the prior art loose body extractor needs to repeatedly take out the extractor when taking out small loose bodies. Re-insertion causes repeated pain to the patient, and it is inconvenient to clamp small loose bodies
