Abstract
The utility model discloses a multi-angle lateral mass type vertebral arch pedicle screw for medical use pertaining to the medical instrument, which comprises a vertebral arch pedicle screw and an angle lateral mass. The utility model is characterized in that the plane where the angle lateral mass and the vertical arch pedicle screw intersect has different obliquities. The utility model can be assembled and operated easily, and can be combined freely according to different pathological change types of the centrum with pathological changes. Multifunction of one screw is truly realized. Besides, the operation fixing accords with physiological curvature of the spine column so iatrogenic injury will not be caused. Thus, the utility model is renewed product of the traditional vertebral arch pedicle screw for medical.
Description
Technical field
This utility model relates to a kind of medical multi-angle lateral mass formula pedicle screw, belongs to medical equipment.
Background technology
For spinal fracture, pedicle screw fixation technology operative treatment commonly used clinically.Pedicle screw at present commonly used clinically only is applicable to the resetting and internal fixation of vertebral fracture of single sections mostly; Though what have is applicable to resetting and internal fixation of multi-segmental vertebral fracture, its vertical connecting rod does not possess flexible, makes the physiological bending that has changed spinal column behind the multi-segmental vertebral body internal fixation easily to cause iatrogenic flat back of the body deformity.The anti-twist power of existing pedicle screw is poor, and every kind of pedicle screw only is applicable to single sick the kind mostly, its different instrument, apparatus is respectively arranged, complicated operation, very inconvenience during use.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, provides a kind of and can plant the selection of (for example: fracture, slippage, unstability etc.) combination in any, easy and simple to handle, fixing reliable medical multi-angle lateral mass formula pedicle screw according to the different parts (from the thoracic vertebra to the lumbar vertebra) of patient's spinal lesion, different disease.
The purpose of this utility model is achieved in that it has the angle lateral mass, is provided with pedicle screw on the angle lateral mass, is characterized in, there is inclination alpha on the plane of intersecting with pedicle screw on the angle lateral mass, and inclination alpha is 90 °～120 °.
This utility model is compared the good effect that has with existing pedicle screw system:
1. install simply, processing ease is not subjected to the influence of pathological changes vertebral body number and diseased region.
2. can select different angle lateral mass according to dissimilar pathological changes, independent assortment has really realized the purpose that a nail is used more.
3, the physiological bending that fixedly meets spinal column can not cause iatrogenic infringement.
Further specify this utility model below in conjunction with drawings and Examples.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Specific embodiments
With reference to figure 1, pedicle screw 1 one ends are shaped on self-tapping screw, can pierce in the bone, and the other end is shaped on screw thread; Pedicle screw 1 passes the hole and 3 vertical connections of angle lateral mass that is shaped on the angle lateral mass 3, and the screw thread that is threaded onto pedicle screw 1 one ends with hold-down nut 6 is fixed.Angle lateral mass 3 has inclination alpha with the plane that pedicle screw intersects, physiological bending according to spinal column, inclination alpha is 90 °～120 °, can satisfy the operation needs, can make the angle lateral mass 3 of a plurality of different angle α in advance, angle lateral mass 3 as 90 °, 95 ° angle lateral mass 3 ... or the like, because pedicle screw 1 is vertical connection with the cross surface mutually of angle lateral mass 3, therefore, when α was different angles, pedicle screw 1 also can tilt accordingly, the angle lateral mass 3 of taking different angles during operation as required gets final product, and is applicable to resetting and internal fixation of each position of vertebral body.
On angle lateral mass 3, also can be provided with vertical connecting rod 2 by hole horizontal, diseased region according to vertebral body, the angle lateral mass 3 of a plurality of different angles of on vertical connecting rod 2, can connecting, to be applicable to resetting and internal fixation of multi-segmental vertebral fracture, easy to use, and can not cause iatrogenic flat back of the body deformity.
This utility model can also be provided with cross bar adapter 7, and cross bar adapter 7 is connected with vertical connecting rod 2 by the hole, is provided with horizontal connecting rod 4 on cross bar adapter 7.Use cross bar adapter 7, horizontal connecting rod 4 can laterally connect two vertical connecting rods 2, the both sides pedicle screw is connected as a single entity, prevent the spinal column distortion.
Operation instruction
Earlier pedicle screw 1 is pierced in the bone, then according to the physiological bending situation of operative site, select proper angle angle lateral mass 3 and vertical connecting rod 2 of appropriate length, respectively vertical connecting rod 2 is connected with angle lateral mass 3, and angle lateral mass 3 is placed in pedicle screw 1 place, tighten each fixed screw 5 and hold-down nut 6 successively.Cross bar adapter 7 is through on vertical connecting rod 2 in advance, and laterally connecting rod 4 and vertical connecting rod 2 pass the hole on the cross bar adapter 7, screw in fixing with fixed screw 8.
Claims (3)
1, a kind of medical multi-angle lateral mass formula pedicle screw, it has angle lateral mass (3), is provided with pedicle screw (1) on angle lateral mass (3), it is characterized in that, there is inclination alpha on the plane that angle lateral mass (3) is gone up and pedicle screw (1) intersects, and inclination alpha is 90 °～120 °.
2, medical multi-angle lateral mass formula pedicle screw according to claim 1 is characterized in that, is provided with vertical connecting rod (2) on angle lateral mass (3), and adjacent angle lateral mass (3) connects by vertical connecting rod (2).
3, medical multi-angle lateral mass formula pedicle screw according to claim 2, it is characterized in that, vertically being provided with cross bar adapter (7) on the connecting rod (2), on cross bar adapter (7), be provided with horizontal connecting rod (4), adjacent vertical connecting rod (2) connects by horizontal connecting rod (4).
