Abstract
The utility model relates to an irregularly-shaped locking type bone fracture plate, which consists of a neck part and a body part, wherein locking holes are respectively formed on the neck part and the body part, the body part and the neck part have an included angle between 90 and 170 degrees, each unit hole formed on the body part consists of a pressurizing hole and a locking hole, and the locking holes are conical screw holes. Locking type screws can be used for locking and buckling the bone fracture plate, ordinary screws can also be eccentrically screwed in the bone fracture plate for generating motive power to reach the effects of pressurization and fixation, the use during minimally invasive surgical operation is convenient, and the irregularly-shaped locking type bone fracture plate has good fixing and holding force for osteoporosis patients and multi- fragment fracture patients.
Description
Technical field:
This utility model is the locking-typed blade plate of the fixed abnormal shape of a kind of human fracture of being applicable to, belongs to medical apparatus and instruments.
Background technology:
In bone surgery, it is fixing often to need to utilize blade plate and bone screw that fracture site is implemented, traditional forcing screw is tightly pressed to periosteum by blade plate and is formed pressurization to the bone section, but it is lower to the shearing force resistance, and shearing force causes forcing screw generation relaxation, blade plate can reduce blood supply to bone to the compressing of periosteum, prolong rehabilitation duration, lock screw has higher resistance to shearing force, but can not be to the pressurization of knochenbruch face, knochenbruch is in the healing that released state is unfavorable for knochenbruch.
The special-shaped locking-typed blade plate of this utility model both can use locking-typed screw snap close in blade plate, also can off-centre be screwed into plain screw and produced power and add press fit.Two kinds of fracture fixation modes are combined, reach best clinical effectiveness.
The utility model content:
This utility model purpose is to provide a kind of abnormal shape locking-typed blade plate, uses when it can conveniently carry out micro-wound surgical operation, to sufferers of osteoporosis face and boniness folded block fracture patient fixedly hold can be arranged also well.
Technology solution of the present utility model is as follows:
The locking-typed blade plate of a kind of abnormal shape, blade plate is made of cervical region and body, forms lock hole on cervical region and the body respectively, body becomes 90～170 degree angles with cervical region, each cell orifice on the body is made of pressurization hole and lock hole, and lock hole is a conical bolt hole, and pressurization forms screw thread in the hole.
Described blade plate cross section inner surface is curved.
Described body forms a plurality of cell orifices.
Described cervical region forms a plurality of lock holes, and the axis of each lock hole is different with the body axis angle.
The beneficial effects of the utility model are:
1, each cell orifice on the body is made of pressurization hole and lock hole, and half is the screw hole that has tapered thread for each cell orifice, second half power forcing screw hole.So both can use locking-typed screw snap close in blade plate, and also can off-centre be screwed into plain screw and produce power and add press fit.
2, locking-typed blade plate cross section is curved, can well fit with bone surface.
3, body becomes 90～170 degree angles with cervical region, uses when the ramped shaped design of this body and cervical region can conveniently be carried out micro-wound surgical operation.
4, cervical region forms a plurality of lock holes, and the axis of each lock hole is different with the body axis angle.The lock hole of blade plate cervical region is multi-angle screw design, has into angle stability after being screwed into lock screw, even to sufferers of osteoporosis face and boniness folded block fracture patient fixedly hold can be arranged also well.

Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the upward view of Fig. 1.
The specific embodiment
Embodiment, see Fig. 1～3, the locking-typed blade plate of a kind of abnormal shape, blade plate is made of cervical region 1 and body 2, form lock hole 11,212 on cervical region 1 and the body 2 respectively, it is characterized in that: 1 one-tenth 90～170 degree of body 2 and cervical region angle, each cell orifice 21 on the body 2 is made of pressurization hole 211 and lock hole 212, lock hole 212 is a conical bolt hole, and pressurization forms screw thread in the hole 211.
Described blade plate cross section inner surface 12 is curved.
Described body forms a plurality of cell orifices 21.
Described cervical region forms a plurality of lock holes 11, and the axis of each lock hole 11 is different with the body axis angle.
Operation principle: each cell orifice 21 of 2 is made of pressurization hole 211 and lock hole 212 on the body, and half is the screw hole that has tapered thread for each cell orifice 21, and second half is power forcing screw hole.So both can use locking-typed screw snap close in blade plate, and also can off-centre be screwed into plain screw and produce power and add press fit.Locking-typed blade plate cross section inner surface is curved, can well fit with bone surface.
1 one-tenth 90～170 degree of body 2 and cervical region angle uses when the ramped shaped design of this body and cervical region can conveniently be carried out micro-wound surgical operation.
