Description

The transdermal therapeutic intra-osteal pressure increases, osteonecrosis mediation decompressor

This utility model relates to technical field of medical instruments, is a kind of operating theater instruments for the treatment of the femur disease.

At present, for treatments such as the necrosis of the high pressure pain of ectocondyle in Avascular Necrosis Of Femur Head, the femur, patella hyperbarism, head of humerus, calcaneus hyperbarism, all adopt operation method to operate on treatments such as decompression, its shortcoming is that only blood circulation around the pathological changes is caused serious destruction again, the cutting operation wound is bigger, complication and sequela are more, effect is also undesirable, the cure rate difficulty reaches 30%, the effective percentage difficulty reaches 60%, how to address these problems, be that at present domestic and international medical circle is extremely paid close attention to the anxious difficult problem that solves that waits.

The purpose of this utility model provides a kind ofly avoids operation to operate on, and can treat the percutaneous intra-osteal pressure mediation decompressor of diseases such as Avascular Necrosis Of Femur Head.

For achieving the above object, this utility model is taked following design: the body that is provided with a cylindricality, front end at body is provided with drill bit, posterior transversal at body is extended with the device handle, rearward end at body is provided with the device neck, in body, be provided with centre bore along axis, this centre bore is in the drill bit inner bending, on the prismatic inclined-plane of drill bit, be provided with a device window, this device window is communicated with centre bore, be provided with the device core body in the centre bore of body, be provided with and the corresponding core neck of the anterior bending of body centre bore at the front end of device core body, the front end of this core neck is provided with and corresponding to core inclined-plane, drill bit prismatic inclined-plane, be provided with the core plug at the device core back-end, be provided with alignment pin beyond the Great Wall at core, be provided with core consent and locating notch in the device neck of corresponding body rear end, be connected with cock cap beyond the Great Wall at core.

When actual therapeutic is used; to early; the patient in mid-term adopts different Therapeutic Method, and the base therapy method is: the decompression of loosening, get patient's lateral position; Ipsilateral is last; do into device labelling, skin degerming; anesthesia is dredged decompressor with this; penetrate in mark; through femoral head central part is adjusted direction up and down in same bone hole, connect to do relief passage in 3 femorals head; dredging the device core of transfering to this mediation decompressor after 2 times; load onto the syringe of 10ml then, the suction of device limit is dialled on the limit, extracts blood out and lowers intra-osteal pressure; and then put on the device core; to dredge decompressor and push the femoral head center, the extractor core connects syringe again, and the mediation decompressor is transferred on marginal not medicine limit; operation finishes; apply wound with adhesive bandage or wound healing patch, with protection wound, prevention infection; treatment future trouble thigh can not bear a heavy burden; general protection 3-6 month, the treatment of 4 weeks once, general one cures to secondary.

Compared with the prior art this utility model has following advantage:

1, can remove and reduce wound, sequela and the complication of cutting operation from, avoid the pathological changes wound of the cutting operation of the blood circulation of depositing on every side fully, just keep blood circulation conditions such as existing blood vessel, nerve.

2, because be closed operation, avoid or reduced operating on the complication of postoperative infection, and in the operation wound not hemorrhage, need not change dressings, not sew up.

3, patient's postoperative need be in hospital, can be movable at once, do not influence normal activity and motion, and need not nurse, need not infuse or transfuse blood.

4, therapeutic effect is reliable, no matter treatment in the past is operative treatment, still the equal difficulty of other method reaches 30% cure rate, adopt this decompressor can reach 62.4% cure rate, the effective percentage difficulty of therapy reached 60% effective percentage in the past, adopt this decompressor treatment effective percentage can reach 98.7%, improved the effective percentage and the treatment rate of treatment greatly.

5, adopt this decompressor treatment femur head necrosis, treatment time has shortened 30-50% than other method, other therapies in the past, treatment time need 1.5-3.Adopt this decompressor can foreshorten to 8-14 month.

6, the patient takes like a shot because the cost less, misery is little, method is simple, curative effect is high, is subjected to patient's welcome.

The utility model is described in further detail below in conjunction with accompanying drawing.
