Abstract
The utility model relates to a novel percutaneous bone grafting appliance, which belongs to the technical field of medical appliances and is suitable for disease operations such as a vertebral fracture operation and the like. The novel percutaneous bone grafting appliance consists of a hollow opening cone (1), a guide needle (2), a hollow reamer (3), a tamping rod (4) and a hopper (5), and is characterized in that: a through hole is formed in the center of the hollow opening cone (1); a through hole is formed in the center of the hollow reamer (3); the tamping rod (4) is step-shaped; the hopper (5) consists of a handle (7), a hopper body (10) and a rod (11); the hopper body (10) is conical; and a lengthened rod is provided with steps. The novel percutaneous bone grafting appliance is used through the following steps of: determining an operation position; inserting the guide needle (2) in a percutaneous way; breaking cortex through the hollow opening cone (1); reaming by using the hollow reamer (3); placing the hopper (5); placing needed broken bones into the hopper (5); grafting bones by using the tamping rod (4) in cooperation with the hopper (5) till operation requirements are met; and strutting and resetting a vertebral body till operation requirements are met, so that the effect of enhancing the vertebral body is achieved.
Description
Technical field
This utility model relates to a kind of novel percutaneous bone grafting apparatus, belongs to medical instruments field, is applicable to diseases such as vertebral fracture operation.
Background technology
Fracture takes place to get more and more at present, in case fracture such as thoracic vertebra and lumbar vertebra take place, people's quality of life descends, and various complication can occur, threat to life, and therefore prevention is fractured important.The mode of treating at present has: the interventional therapeutic technique of Wicresoft, the operation of balloon expandable kyphoplasty, advantage are in fixing fracture, can recover vertebral height and spinal column etc. to lose the arrangement of shape face, and operating time is short, and pain is few, and recovery time is short.
Along with the prolongation of human average life and increasing of the aged, the sickness rate of osteoporosis raises just year by year.Osteoporotic fracture sees with compressed fracture of thoracic vertebra and lumber vertebra that especially this is a kind of people's of having a strong impact on mobility and the disease of quality of life more.Traditional treatment is that long-term bed, brace are fixed and pharmacotherapy; But be difficult to alleviate the refractory back pain; Can not recover vertebral height (like bow-backed deformity); And the minimizing of activity further causes osteoporosis behind the long-term bed, and bone loss, bone strength descend, and are prone to cause fracture to take place once more.Long-time bed can produce the other system complication, and long-time bed can increase state of an illness risk, and long-time bed increases the weight of osteoporosis, amyotrophy.ADL descends obviously, and the risk that fracture takes place is once more arranged, and about 80% patient can not return to the level of activation before hindering, and the nursing task is heavy, and vertebral fracture brings pain to people, and mobility obviously descends, and influences patient's limb functional recover.
Summary of the invention
This utility model provides that a kind of to have wound little, the respond well characteristics of vertebral body distraction reduction, firm a kind of novel percutaneous bone grafting apparatus safe, easy and simple to handle.
The technical scheme of this utility model is following:
A kind of novel percutaneous bone grafting apparatus by hollow open circuit bore (1), guide pin (2), hollow rose bit (3), tamper (4), funnel (5) is formed; It is characterized in that: hollow open circuit awl (1) central through hole; Hollow rose bit (3) central through hole, tamper (4) is step-like, funnel (5) is made up of handle (7), infundibular body (10), bar (11); Infundibular body (10) is a taper, and extension bar has step.
Hollow open circuit awl (1) head has the taper cutting edge, is used for brokenly cortex.
Hollow rose bit (3) head is a taper, and cutting edge is arranged, and screw thread is arranged, and makes things convenient for reaming.
Tamper (4) is made up of tamper body (9) and handle (7), tamper body (9) central through hole.
Funnel (5) plays guiding function, can bone-grafting material be pushed in the service aisle, and convenient the application shortened operating time.
Through diagnose medical conditions such as CT or X-ray before the art, implement operation: confirm bone grafting position and broken bone quantity.At first confirm surgery location, percutaneous inserts guide pin (2), the broken cortex of hollow open circuit awl (1); With hollow rose bit (3) reaming; Insert funnel (5), required broken bone is inserted in the funnel (5), unite funnel (5) bone grafting to requirements of operation with tamper (4); Vertebral body is strutted, is reset to requirements of operation, thereby reach the effect of strengthening vertebral body intensity.
Adopt the present technique scheme, beneficial effect is: both protected blood fortune around the fracture, promoted union of fracture, effective repairing bone defect strengthens the bone grafting effect, quickening patient's limb rehabilitating again.
This utility model is applicable to diseases such as vertebral fracture, and surgical openings is little, and wound is little; Operation is little to the patient body influence, and the patient suffering is few, and recovery time is short; Vertebral body struts, reset effect is good, has firm safe, easy and simple to handle, advantage that cost is low, is suitable for the orthopaedics clinical application.
