Description
Technical field
This utility model relates to technical field of medical instruments, is specifically related to a kind of expansion gear for the treatment of compression fracture of vertabral body.
Background technology
Treatment compression fracture of vertabral body, general employing two kinds of technology, one is vertebroplasty, by flowable reinforcing material, normally polymethyl methacrylate, injects damaged vertebral body by puncture needle.After injecting soon, liquid filling material is polymerized cement and hardness increases, and from internal support vertebral body, alleviating pain also prevents from subsiding further through vertebral body.Another kind of technology is balloon kyphoplasty, is inserted in damaged vertebral body, then expands distensible device.Take out distensible device, namely this operation forms a cavity in bone, can fill bone cement or other loading material in the cavities, enables the bone load-bearing of fracture.Thus strengthening damaged vertebral body, protect it to avoid subsiding further.
This series products Problems existing at present: bone cement seepage and bilateral puncturing operation are costly.
Bone cement seepage is complication the most common.Carrying out in PVP and PKP operation process, needing injection bone cement to recover vertebral height, one-sided puncture injection bone cement easily causes vertebral height to recover uneven, and causes complication.Recover evenly to vertebral height, then need bilateral to puncture, surgery cost is high.
Publication number is the inflatable device that patent discloses a kind of controllable bending treatment compression fracture of vertabral body of CN 104434280 A, comprise: a fixed handle, one end of described fixed handle is provided with a breeches joint, the other end of described fixed handle is rotating is provided with a rotary handle, there is in described fixed handle the through hole of the described rotary handle of a connection and described breeches joint import, one inner screw is through described through hole, and one end of described inner screw is threaded with described rotary handle; The outlet of described breeches joint is connected with an outer sheath, described outer sheath is provided with an inflatable pouch and a head end; One end of one bracing wire is connected with described head end, and the other end of described bracing wire is connected with described inner screw.Its technical problem existed is that outer sheath flexural resilience is poor, and dynamics is bad control, brings difficulty to operator.
