Abstract
An insert device for treating necrosis of femur head is composed of a femur head puncture unit consisting of surface borer, bone marrow channel generator comprising metallic tube and handle, external sleeve tube and internal core with front tip end, and a treating tube consisting of a flexible plastic guide tube with blind front end and a guide wire inserted in said guide tube.
Description
Technical field
The invention belongs to the medical apparatus and instruments of treatment femur head necrosis, particularly relate to a kind of intervention therapeutic apparatus for necrosis of head of femur.
Background technology
Ischemic necrosis of femoral head is caused that by capital disturbance of blood circulation promptly marrow is intrinsic pressure increases, and microcirculation is retarded by silt in the marrow, the venous return obstacle, thus cause the tremulous pulse blood supply insufficiency, cause osteonecrosis; Therefore, improve the theoretical foundation that capital blood circulation becomes the treatment aseptic necrosis of femoral head.The common method of treatment aseptic necrosis of femoral head has three kinds at present, and a kind of is non-operative treatment, and this method comprises Drug therapy and physical therapy, and its effect is to alleviate heavy burden, stop or alleviating the joint degeneration process, prevents collapse of the femoral head; The used medicine of Drug therapy has vasoactive class, blood fat reducing and lipid scavenger, promotes the fibrinolytic class that its effect is the blood circulation that improves necrotic femoral head; Another kind is the palliative operation therapy, and it comprises that the thigh transplantation of core blood pressure lowering art, vascular pedicle or the flesh base of a fruit, vascular bundle thigh are implanted into art; The third is Replacement of Hip Joint and total hip joint, in being applicable to, end-stage patients; Above-mentioned three kinds of Therapeutic Method all exist certain limitation, can not obtain better therapeutic effect, therefore, develop a kind of can be directly to extracting thing, and can be to the medical apparatus and instruments of necrotic zone for the treatment femur head necrosis of medicine, this is one of problem of paying close attention to of medical circle.
Summary of the invention
The object of the present invention is to provide a kind of blood that can improve necrotic femoral head to transport, lower the intervention therapeutic apparatus for necrosis of head of femur that bone marrow is intrinsic pressure, be convenient to supply to the femur head necrosis zone medicine.
The object of the present invention is achieved like this; It comprises femoral head sting device and treatment pipe two parts, it is characterized in that described femoral head sting device by epidermis awl, bone marrow tunnel-shaped grow up to be a useful person, trocar sheath and inner core constitute, described treatment pipe is made of conduit, seal wire; Described bone marrow tunnel-shaped is grown up to be a useful person by metal tube and handle be combined into, the front end indentation of this metal tube, described trocar sheath can be enclosed within on the inner core, the length of inner core is greater than the length of trocar sheath, the front end of inner core is the prong shape, and described conduit is a plastic flexible pipe, and its front end is a cecum, the anterior sidewall of this flexible pipe is provided with delivery outlet, and described seal wire can be inserted in the conduit.
Intervention therapeutic apparatus for necrosis of head of femur provided by the present invention, have simple in structure, easy to use, for extracting the femur head necrosis thing or providing new approach for medicine to the femur head necrosis zone.
In conjunction with the accompanying drawings and embodiments, it is as follows that the invention will be further described.

The specific embodiment
The present invention includes femoral head sting device and treatment pipe two parts, in Fig. 1 to Fig. 6, femoral head sting device of the present invention is by epidermis awl 4, the bone marrow tunnel-shaped grows up to be a useful person 16, trocar sheath 10 and inner core 8 constitute, described bone marrow tunnel-shaped grows up to be a useful person 16 by metal tube 18 and handle 17 be combined intos, the front end indentation 19 of this metal tube 18, end at handle 17 is provided with connector 15, described trocar sheath 10 can be enclosed within on the inner core 8, the length of inner core 8 is greater than the length of trocar sheath 10, the front end of inner core 8 is prong shape 7, the front end of described trocar sheath 10 be provided with sawtooth 110 described bone marrow tunnel-shaped grow up to be a useful person 16 can with get thing rod 13 and match, get thing rod 13 by barred body 14 and end handle be combined into, described length of getting thing rod 13 is at least greater than grow up to be a useful person 2 centimetres of 16 length of bone marrow tunnel-shaped, and its diameter is less than grow up to be a useful person 16 internal diameter of bone marrow tunnel-shaped.
In Fig. 7, Fig. 8, described treatment pipe is made of conduit 20 and seal wire 23; Described conduit 20 is a plastic flexible pipe, and its front end is a blind hole 22, and these flexible pipe 20 anterior sidewalls are provided with delivery outlet 21, and described seal wire 23 can be inserted in the conduit 20.
When the present invention uses, allow the patient lie on the back on X ray examination bed earlier, patient's buttocks bed hedgehopping 15-20 degree, conventional drape, local anaesthesia, under the X line monitors, thrust epidermis and soft tissue by epidermis awl 4 earlier, then inner core 8 is inserted in the outer tube sleeve 10, make both be combined together from femoral greater trochanter slightly the below, penetrate a burst cortex together to the femur head necrosis direction, treat that trocar sheath 10 is fixed in burst cortex after, withdraw from inner core 8, introduce the bone marrow tunnel-shaped and grow up to be a useful person 16, push ahead by pressing down, communicate with necrotic zone until the bone passage, behind the X line justification with rotary handle 17, on growing up to be a useful person the connector 15 of 16 rear ends, the bone marrow tunnel-shaped can connect the suction syringe, firmly negative pressure-pumping takes out under negative pressure together, and reuse is got thing rod 13 and disclosed sphacelus, and repeatedly for several times, until no sphacelus sucking-off; After treating that sphacelus taking-up and passage form, conduit 20 enters in the femur head necrosis zone along trocar sheath 10 under the assistance of seal wire 23, slowly withdraw from trocar sheath 10 then, conduit 20 rear ends can connect injecting apparatus, injection of contrast medium is made bone marrow vein radiography for the first time, fixes conduit 20 at last the patient is sent into the ward.
