Abstract

A pressure reducer for percutaneous treating osteoendo- hypertension and osteoischemic necrosis by non-open operation has a cylindrical main body with sharp lower end and top handle. A core cavity is arranged in the top handle and main body and communicated with the window of sharp lower end. A core is set up in the core cavity. Its advantages are simple structure, convenient application, high curative effect, low cost and high cure rate and effective rate.

Description

The transdermal therapeutic intra-osteal pressure increases disease and ischemic necrosis of bone mediation decompressor

The present invention 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 invention is to provide and a kind ofly avoid operation to operate on, can treat the percutaneous intra-osteal pressure mediation decompressor of diseases such as Avascular Necrosis Of Femur Head.

For achieving the above object, the present invention takes following design: a kind of transdermal therapeutic intra-osteal pressure increases disease and ischemic necrosis of bone mediation decompressor, it is provided with the device body of a cylindricality, be provided with the device cutting edge of a knife or a sword in the lower end of device body, be provided with the device handle, in device handle and device body, be provided with the core chamber in the upper end of device body, this core chamber is in the inner bending of device cutting edge of a knife or a sword, be provided with a Qifeng window on the device cutting edge of a knife or a sword, this Qifeng window is communicated with the core chamber, is provided with the device core body at the core intracavity.

Be provided with bottom, core chamber in the lower end of device core body and bend corresponding core neck, the lower end of this core neck is provided with the core cutting edge of a knife or a sword, is provided with the core plug in the upper end of device core body, is provided with the location foresight beyond the Great Wall at core, place, core chamber, device handle upper end in correspondence is provided with core consent and locating notch, holds beyond the Great Wall at core to be connected with cock cap.

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 body of transfering to this mediation decompressor after twice; 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 body; to dredge decompressor and push the femoral head center, the extractor core body 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 3-4 month, the treatment of 4 weeks once, general one cures to secondary.

Compared with the prior art the present invention 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 invention will be further described below in conjunction with accompanying drawing.

Fig. 4 is that Fig. 2 A is to sketch map

Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4; This decompressor adopts first-class high-quality steel to do raw material, make a cylindrical or oval-shaped device body 4, be provided with device cutting edge of a knife or a sword 1 in the lower end of device body 4, be provided with butterfly device handle 5 in the upper end of device body 4, be provided with cylindrical core chamber 3 in butterfly device handle 5 and device body 4, this cylindrical core chamber 3 is provided with a Qifeng window 14 in the inner bending of device cutting edge of a knife or a sword on device cutting edge of a knife or a sword 1, this Qifeng window 14 is communicated with core chamber 3, is provided with the device core body 2 that can insert, extract out in core chamber 3.

Be provided with 3 bottoms, core chamber in the lower end of device core body 2 and bend corresponding core neck 13, the lower end of this core neck 13 is provided with core cutting edge of a knife or a sword 12, be provided with core plug 8 in the upper end of device core body 2, on core plug 8, be provided with location foresight 11, place, core chamber, device handle 5 upper end in correspondence is provided with core consent 9 and locating notch 10, and when device core body 2 inserted in the core chamber 3, its location foresight 11 matched with locating notch, be connected with cock cap 7 in core plug 8 upper ends, be provided with device neck 6 in upper end, butterfly device handle 5 middle parts.

This decompressor is mainly used in treatments such as the high pressure pain, patella hyperbarism, head of humerus, bone inner high voltage disease, calcaneus hyperbarism of ectocondyle in the Avascular Necrosis Of Femur Head, femur, it is non-cutting operation therapeutic device, through a large amount of clinical patient treatment proofs, evident in efficacy, be better than other Therapeutic Method in the past, high social and economic benefit are arranged, and are the desirable apparatuses for the treatment of above-mentioned sufferer at present both at home and abroad.
