Problems solved by technology
However, in elbow arthroscopic surgery, the accurate guidance of the Kirschner wire has always been a major problem in this field. At present, the guide frame used in the prior art is not flexible enough, and it is inconvenient to install and wear, which greatly increases the difficulty of the operation.

Embodiment Construction
[0018] like Figure 1-4 A coronoid fracture positioning guide for surgical elbow arthroscopy is shown, which is used for positioning the injured arm and guiding the Kirschner wire during elbow arthroscopy. like figure 1 As shown in, the present invention comprises two arm sleeves, and described arm sleeve is respectively forearm arm sleeve 1 and big arm sleeve 2, and described small arm sleeve 1 and big arm sleeve 2 are installed in the size of the wounded person respectively. arm. The specific structure of the arm sleeve is more, for example, the arm sleeve can be two clamp-type fastening sleeves, and the arm is fixed by two semicircular hoops. But because for different patients, the thickness of its arm has obvious difference, this clamp type fastening sleeve needs to change different washers to adapt to arm size.
[0019] Therefore the present invention proposes a kind of novel arm cover simultaneously, as figure 2 As shown in , the arm sleeve includes a C-shaped sleev...

The invention relates to the field of surgical assisting instruments. The invention aims at providing a location guiding device for surgical elbow joint microscopic coronoid process fracture, and thelocation guiding device is convenient to wear and high in flexibility. The technical scheme adopted by the invention is as follows: the location guiding device comprises two arm sleeves, namely a small arm sleeve and a big arm sleeve, wherein the small arm sleeve and the big arm sleeve are connected through an angle adjusting mechanism; the angle adjusting mechanism comprises an arc-shaped guidingslot and a telescopic rod which cooperate with each other, one end of the telescopic rod is connected with the small arm sleeve, and the other end of the telescopic rod penetrates into one end of theguiding slot and is in sliding fit with the guiding slot; and a large-sized mounting region is formed in one end, far from the big arm sleeve, of the guiding slot, and an adjusting gear is mounted inthe guiding slot corresponding to the mounting region. The location guiding device has two functions of fixing arms of wounded people and guiding a kirschner pin and is convenient to mount and wear,and angles are flexibly adjusted.
Description
technical field [0001] The invention relates to the field of surgical auxiliary instruments, in particular to a positioning guide for coronoid process fractures under surgical elbow arthroscopy. Background technique [0002] Coronoid fracture is a type of elbow joint injury, which is mostly caused by direct rigid compression such as collisions and falls. Since the fracture of the coronoid is located at the elbow joint, its internal soft tissue structure is relatively complex. Large-scale surgical incision is performed to reduce the fracture site, and internal fixation is used to restore joint alignment. However, this traditional method has great damage to soft tissues around the elbow joint, and postoperative recovery is slow. With the improvement of medical equipment and the rapid development of endoscopic technology in recent years, elbow arthroscopy has gradually been promoted in clinical practice. Elbow arthroscopy monitors under the microscope and uses Kirschner wires t...
