Description
Technical field
The present invention relates to a kind of Wicresoft extension arm pedicle nail, belong to medical instruments field.
Background technology
The Wicresoft of operation, functionalization and intellectuality are the signs of modern surgery technology, it also is the developing direction of following surgical technic, the vertebral column minimally invasive surgical technic is that the conventional spinal operation is combined with less invasive techniques, reduce operation to patient's wound in the hope of reaching, alleviate grieved uncomfortable behind the operation in patients, shorten bed and hospital stays, accelerate the rehabilitation of patient's postoperative function, and effort keeps the integrity of spinal column normal anatomical structures, thereby reach the highest goal of postoperative preservation spinal normal physiological function, yet, minimally invasive spine surgical not only needs the auxiliary of advanced instrument and equipment and supports, but also require the patient to have very high tactile sensing degree, spatial discrimination, and can be by the ability of narrow service pipe skilled operation, the neighbour important nerve in spinal column the place ahead particularly, blood vessel and internal organs, this brings great technical difficulty and challenge just for carrying out of spinal column anterior minimally invasive operation.
The Minimally Invasive Surgery of percutaneous cervical arc root screw technique for fixing and percutaneous channel operation technology, peeling off of paraspinal muscle farthest avoided in this class operation, reduce operation wound, and have wide range of applications, huge prolapse of lumbar intervertebral disc be can treat or lumbar spinal stenosis, scoliosis etc. deviate from, percutaneous passage technology surgical field of view is openr than MED, can use the routine operation apparatus, the doctor operates grasp easily, and the percutaneous cervical arc root screw fixed system is to finish drilling in the guiding of fluoroscopy during operation to finish, wound is little, precision is high, and therefore, this class operation is the Minimally Invasive Surgery mode that compares main flow both at home and abroad, treat in this way prolapse of lumbar intervertebral disc, the lumbar spinal stenosis case, the general reaction of patient's postoperative is that pain is little, postoperative drainage is few, recovers fast.
China's minimally invasive spine surgical technic is started late, and the minimally invasive spine surgical technic is in China's fast development, but the minimally invasive spine surgical technic is carried out imbalance.
Summary of the invention
The invention provides a kind of operation wound Wicresoft's extension arm pedicle nail little, easy and simple to handle.
Technical scheme of the present invention is as follows:
Wicresoft's extension arm pedicle nail is comprised of Wicresoft's rivet nut (1), Wicresoft's extension arm adapter (2), opening briquetting (3), connection plug screw (4), it is characterized in that: Wicresoft's rivet nut (1) is grouped into by threaded portion and ball head, central through hole, there are interior six sides at the bulb place, and outer surface has symmetrical flat horizontal surface; Wicresoft's extension arm adapter (2) is hollow structure, and the left end head has screw thread, and sphere is all arranged inside and outside the left end head, and there is annular groove on the surface, and right-hand member has the symmetrical openings groove, and there is U-shaped groove at the middle part.
Wicresoft's rivet nut (1) bulb partly has symmetrical flat horizontal surface, and be connected with opening briquetting (3), make Wicresoft's extension arm pedicle nail realize radial motion, and left and right sides jiggle effect, rivet nut adopts hollow design, the associating guide pin is implanted rivet nut, and it is more accurate to make rivet nut implant the orientation, satisfies the minimal invasion requirements of operation.
Wicresoft's extension arm adapter (2) brachium 85mm, the nail arm can expose body surface during operation, makes the doctor can observe intuitively and adjust the planting-peg tendency, makes the planting-peg process more accurately simple, realizes the minimal invasion operation.Wicresoft's extension arm adapter (2) can only swing in the pitman sagittal plane with respect to Wicresoft's rivet nut (1), pendulum angle is-25 °～+ 25 °, this unique design can be convenient to put rod in the middle of operation process, highly losing appears in pyramidal support and when pressurization and vacation struts carrying out to overcome again common universal nail, the phenomenon of pressurization, universal nail is convenient to put rod for it and the single shaft nail is strutting, the sets of advantages of highly not losing during pressurization together, the arm afterbody adopts closure designs, avoid following closely the arm distending, make accuracy of thread higher, cooperate tightr, the lock rod is more fastening, the operation technique of being more convenient for.
Opening briquetting (3) central through hole, its middle part, hole has spherical, and there is arc-shaped groove the upper surface.
Implement fixing operation by X-ray examination or navigation system, determine surgery location, determine the quantity of Wicresoft's extension arm pedicle nail and spinal rod, under the guiding of X-ray examination or navigation system, implement operation: the percutaneous puncture location, utilize mis instruments boring, reaming, implant Wicresoft's extension arm pedicle nail, penetrate spinal rod and pre-bending to requirements of operation, tighten and connect plug screw (4), implement distraction reduction according to clinical demand, tighten and connect plug screw (4) to final locking state, the stable fixing function of realization.
The present invention is in operation process, and operative incision is little, and protection muscle and ligament normally adhere to epispinal, do not need to expose spinal column, safety, implants accurately.
The present invention has feasibility in morphology, and each parameters of operating part has certain selection range, can rebuild the stability of vertebral body, and firm, easy and simple to handle, the novel internal fixation system that meets the anatomy of spine structure of safety is suitable for Orthopedic Clinical and applies.
