Description
Technical field
This utility model relates to technical field of medical instruments, specifically, is medical polyethylene artificial bone composites and kit.
Background technology
Medical polyethylene artificial bone composites is widely used in bone surgery, and artificial bone is widely used in the sub-subject of the orthopaedics such as spinal surgery, bone tumor section, hands surgery, and some artificial bones can be prepared into injection type, and adopts the method for non-Wicresoft to improve Bone Defect Repari effect.Artificial bone leaves over the filling bone grafting that Cranial defect or operation cause Cranial defect after can being applied to trauma fracture reduction at present, knitting is bad, bone tumor leaves over the filling bone grafting of defect after striking off, the orthopedic bone grafting of joint fusion, Cranial defect when artificial joint is overhauled is filled, spinal operation Intervertebral fusion, after compression fracture of vertabral body resets, full strengthening is fixing, sufferers of osteoporosis face strengthening vertebral body, cervical spinal stenosis decompression way of escape double door hands art, bone cyst injection fillers, with autologous bone mixing bone grafting, infectious Cranial defect needs bone transplantation substitute bone person with other, bone grafting is filled as the carrier local sustained release Drug therapy of compound selectivity antibiotic or chemotherapeutics or bone morphogenetic protein(BMP) etc. and Cranial defect and Cranial defect, for the moulding bone grafting in bone district, the situations such as empty bone grafting are followed closely after screw takes out.
Artificial bone filling mode conventional at present comprises: the first does not need the filling mode of instrument, namely first wanting bone collection position to handle well, strike off pathological tissues, and make affected part have sufficient blood supply, manufacture the environment of a similar Fracture Hematoma phase, then appropriate artificial bone granule is carefully put into the position of filling bone defects, and cover with soft tissue.The mode of the second Wicresoft injection artificial bone, namely first under C arm machine or CT guiding, puncture needle is preset in vertebral body to be injected or Cranial defect place, according to defect size, select suitable packing dosage, powder is fully reconciled into the slurry slightly rare compared with toothpaste in the ratio prepared (a bag powder joins a consolidation liquid) with consolidation liquid in 20m sterile syringe, tuberculosis enters in the little syringe of 1-2m for subsequent use again, artificial bone slurry syringe will be filled be connected with puncture needle, slowly pressurize subsequently, slurry is expelled to position to be filled, stops after filling is satisfied.Fill position intrinsic pressure higher time, pressure injector can be selected or with balloon expandable vertebral body etc., before the injection to the pretreatment of filling position, before injection, answer air in emptying syringe.The third iFuse Wicresoft sacroiliac joint integration technology, namely soft tissue protector is inserted along steinman pin under fluoroscopy, strut skin, subcutaneous fat and muscular tissue, support to ilium surface of bone, under the protection of bit sleeve, ilium is pierced along steinman pin direction electric drill, rumpbone is entered by sacroiliac joint, pierce depth desired, take out bit sleeve, along steinman pin and boring direction, open circuit device is knocked in sclerotin to depth desired, after open circuit device takes out, insert the passage of fusion device and ready, the iFuse fusion device choosing suitable types is inserted along ready passage, use fusion device push rod that the iFuse fusion device of suitable types is pushed reserved passageway.
Injection artificial bone and kit complex operation step thereof, and will avoid Material injection being entered in canalis spinalis, blood vessel and articular cavity, avoid producing compressing to nerve or increasing the weight of damaging surrounding tissue, avoid causing and comprise nerve injury, paralysis, dead serious consequence, and the artificial bone be in harmonious proportion can not too rare can not be too thick, too rarely easily organize diffusion towards periphery, too thick dyschezia is to inject, injection process can not more than 15 minutes, so need higher familiarity and doctor's experience.And the supporting apparatus of iFuse fusion device is many, operating procedure is complicated, and be difficult to grasp at short notice, learning curve is precipitous, needs longer time learning and mastering.
