Description
Technical Field
The utility model relates to a femoral head treatment facility technical field specifically indicates an integral type trepan protective sheath for femoral head necrosis treatment.
Background
Femoral head necrosis is a lesion of further ischemia, necrosis, fracture of trabecular bone and collapse of femoral head caused by poor local blood circulation of femoral head due to various reasons, and collapse and secondary osteoarthritis occur within 1-4 years without effective treatment. For the treatment of this disease, there is no standard method for curing patients of different types and stages. By combining the therapeutic guidelines for femoral head necrosis and a plurality of related literature data, it can be seen that for early patients in Ficat stage I, more satisfactory therapeutic effects are obtained by adopting drug therapy, physical therapy, femoral head medulla decompression and DSA interventional therapy; for patients in the advanced Ficat stage IV, joint replacement is consistently considered by clinical experts as its most effective treatment; however, for Ficat II and Ficat III patients with femoral head necrosis, especially young patients, most of whom are desirous of head-protection therapy without joint replacement, the related literature shows that there are many methods for head-protection therapy for such patients, which are summarized in three categories, namely core decompression, bone grafting (with/without blood vessels), and osteotomy.
When using a trepan to resect a bone block, the trepan often needs to enter the intervertebral foramen under the protection of a protective sheath. At present, protective case's front end is equipped with the baffle portion of duck tongue shape, and the periphery of baffle portion is great, is difficult for getting into intervertebral foramen, and the trepan is more by the part that baffle portion sheltered from, and the quantity that leads to excision bone piece is less, and current protective case is difficult for fixing a position when using, and medical personnel's the operation degree of difficulty is higher.
SUMMERY OF THE UTILITY MODEL
For solving above-mentioned current difficult problem, the utility model provides a narrow setting makes better entering behind the preceding wide of streamline head, when the point of operation is implemented to needs, suppresses the inlet port with the level pressure air pump for the gasbag expands slightly, and fixes a position protective case jointly with the streamline head, makes the more accurate integral type trepan protective sheath that is used for the necrosis of femoral head that the operation goes on.
The utility model adopts the following technical scheme: the utility model relates to an integral type trepan protective sheath for femoral head necrosis treatment, place guide arc, inflation positioner, protective case and handle including the trepan, protective case is inside cavity and open-top's cavity tubulose setting, the trepan is placed the front end that the guide arc located protective case, the rear end of protective case is located to the handle, inflation positioner locates on protective case is close to the trepan and places the both sides of guide arc, inflation positioner includes gasbag, gas tube and flexible inflation spare, flexible inflation spare symmetry is located protective case and is close to the trepan and place on the both sides of guide arc, the gasbag is located in the flexible inflation spare respectively, the one end and the gasbag intercommunication of gas tube, one side of handle is located to the other end of gas tube.
Furthermore, the front end of the protective sleeve is provided with a streamline head, and the streamline head is in a shape of turning with wide front and narrow front.
Furthermore, the top of the streamline head is provided with a scratch-proof fillet.
Furthermore, the top opening of the protective sleeve is flat-topped.
Furthermore, the air inlet hole is arranged on the handle of the inflation tube.
Furthermore, a holding groove which is recessed inwards is formed in the side end of the handle.
Adopt above-mentioned structure the utility model discloses the beneficial effect who gains as follows: this scheme an integral type trepan protective sheath for femoral head necrosis treatment, narrow setting makes better entering behind the preceding wide of streamline head, when the point that needs implement the operation, suppresses the inlet port with the level pressure air pump for the gasbag expands slightly, and fixes a position protective case jointly with the streamline head, makes the operation go on more accurately.
