Medical orthopaedic clinical free body extractor

Abstract

The invention discloses a medical orthopaedic clinical free body extractor, which comprises an external pipe body, a movable groove, an inner pipe, a collecting frame, a collecting handle and a storage cover, according to the medical orthopaedic clinical free body extractor, a gap reserved between an external frame and a butt-joint frame is aligned with a free body, a clamping bent plate leaves the butt-joint frame and rotates towards the direction of the gap, the gap is reduced, the clamping bent plate and the butt-joint frame clamp and take out the free bodies, the taken-out free bodies enter the storage net frame through the interior of the built-in main pipe after the clamping bent plate and the butt-joint frame loosen clamping, the storage net frame collects the free bodies in a centralized mode, and normal use of the extractor is kept. After more free bodies are stored in storage net frame, threaded column body is taken out from storage handle to be cleaned. According to the structure, the free bodies can be taken out from the articular fossa and stored in a clamping mode, operation is convenient and fast, the free bodies are not prone to sliding off, and the extractor can be continuously used.

Description

technical field [0001] The invention relates to the field of orthopedic clinical technology, in particular to a medical orthopedic clinical loose body extractor. Background technique [0002] In orthopedic clinics, joint locking often occurs in loose bodies of the knee joint. Sudden joint locking occurs due to smaller loose bodies being squeezed between the articular surfaces. 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 mechanical stimulation of the periosteum, or palpable mobile mass due to loose bodies swimming to the superficial part. In addition, when the lock is unlocked, the patient may hear or feel a sound, a false sense of movement, and some may cause kneeling and falling, so the loose body needs to be taken out of it. [0003] At present, it is often necessary to clean up loose bodies in the articular fossa in orthopedic clinics. The usual met...

Problems solved by technology

[0003] At present, it is often necessary to clean up loose bodies in the articular fossa in orthopedic clinics. The usual method is to clamp and remove the loose bodies with surgical forceps under arthroscopy, and arthroscopic surgery is rapidly promoted due to its advantages of small trauma, fast recovery, and definite curative effect. With the development of minimally invasive joint surgery, arthroscopic removal of osteophyte loose bodies has become the preferred surgical option. Most of the joint loose bodies are flat and oval, smooth and free, and difficult to remove. Forceps, because the traditional surgical forceps are not special equipment for arthroscopy, it is difficult to open the forceps after entering from the minimally invasive incision, the operation is more troublesome, and it is easy to slip out during the removal process, which greatly increases the difficulty of the doctor's operation, and the workload is relatively heavy. Large, difficult to meet the needs of use
