Description
Technical field
This utility model relates to a kind of fracture of rib to blade plate, belongs to medical apparatus and instruments.
Background technology
Metal bone fracture plate, according to the shape of skeleton, designs according to bionical, and object is to reduce as far as possible to pre-bend the destruction of the product stress caused due to hone lamella.Meanwhile, the different parts used according to product, predetermined screw hole spacing and aperture.According to the load-bearing needs at position, determine material therefor.
Above tradition is loose structure to blade plate on its surface, uses standard screw mandrel screw.
Rib uses very inconvenience, when docking rib, need surgical incision skin, subcutaneous, and extensively peel off periosteum, then steel plate is close to surface of bone, screw need pass through medial periosteum, screw very easily causes puncturing pleura in torso model inside, produces secondary injury to human body, and damage is large, have a big risk, and after recovering again, need operation to take out.
Summary of the invention
The purpose of this utility model is, provides a kind of fracture of rib to blade plate, realizes external docking rib.
For achieving the above object, the technical solution adopted in the utility model is:
Fracture of rib, to blade plate, comprises buttcover plate and special-shaped screw, and described buttcover plate is provided with horizontal slotted eye and longitudinal slot, and transverse groove pore size distribution is at the two ends of buttcover plate, and longitudinal slot is positioned at the centre of horizontal slotted eye; The front end of described special-shaped screw is deep trouth screw thread, and the rear end of special-shaped screw is standard thread and is furnished with the nut being anchored on buttcover plate both sides, and rear end face establishes the screw edge of a knife.
As preferably, the wide of buttcover plate is 16mm, and long is 80-200mm, and thick is 2-3mm.
As preferably, described horizontal slotted eye is long is 10mm, and wide is 6mm, and the long limit of transverse holes is 5mm to the end of buttcover plate.
Further, described deep trouth screw thread deepens 1mm on the basis of rear end standard screw mandrel, and the screw edge of a knife is the one in interior hexagonal, outer-hexagonal, the cross edge of a knife and a word edge of a knife.
The utility model has the advantage of: this screw nose threads groove depth used blade plate, be spongy bone silk, rear end is standard screw mandrel, is provided with slotted eye anyhow to blade plate.This utility model uses outward at human body, and the spongy bone silk of screw front end reaches the inner face of endosteal lamella, and screw mandrel establishes nut to be fixed on buttcover plate in human body skin outside.Trial edition utility model can carry out local anesthesia or intercostal anesthesia to patient.Use this utility model 4-6 week contact after surgery buttcover plate, namely can take off in the fiber connection phase, not use bone and heal completely.Use new restoring is fast, little to human injury.

Detailed description of the invention
This utility model structure as shown in Figure 1, comprises buttcover plate and special-shaped screw, and described buttcover plate is provided with horizontal slotted eye and longitudinal slot, and transverse groove pore size distribution is at the two ends of buttcover plate, and longitudinal slot is positioned at the centre of horizontal slotted eye; The front end of described special-shaped screw is deep trouth screw thread, and the rear end of special-shaped screw is standard thread and is furnished with nut, and rear end face establishes the screw edge of a knife, and the screw edge of a knife is the one in interior hexagonal, outer-hexagonal, the cross edge of a knife and a word edge of a knife.Deep trouth screw thread deepens 1mm on the basis of rear end standard screw mandrel, ditch is deepened, clear-cut margin, is convenient to be screwed in bone.
Embodiment 1
The wide of buttcover plate is 16mm, and long is 80mm, and thick be 2mm, and horizontal slotted eye is long is 10mm, and wide is 6mm, and the long limit of transverse holes is 5mm to the end of buttcover plate.
Embodiment 2
The wide of buttcover plate is 16mm, and long is 200mm, and thick be 3mm, and horizontal slotted eye is long is 10mm, and wide is 6mm, and the long limit of transverse holes is 5mm to the end of buttcover plate.
Need Kirschner wire be adopted to penetrate rib outside plate at the rib place of patient before this utility model uses, then special-shaped screw front end being screwed into rib makes this special-shaped screw ailhead withstand the endosteal lamella inner face of patient's rib, then standard screw mandrel screws on nut near skin, to be rivals in a contest fishplate bar, buttcover plate lateral surface screws in nut again, buttcover plate and special-shaped screw is fixed.
Special-shaped screw is screwed in rib, due to screw silking, there will be the problem that special-shaped screw tilts to all directions, if the angle tilted between special-shaped screw is not very large, need not correct.The angle tilted between special-shaped screw is large, utilizes the slotted eye in length and breadth of buttcover plate to insert the special-shaped screw of different angles respectively, to adapt to the angular slope between special-shaped screw.If special-shaped screw tilts along buttcover plate, can by special-shaped screw through longitudinal slot; If special-shaped screw vertical butt joint plate tilts, can by different in nature screw through horizontal slotted eye.Special-shaped screw pierces into the endosteal lamella inner face into patient's rib, and rear end standard screw mandrel is sprained nut and buttcover plate and human body fitted tightly.
This utility model carries out local anesthesia or intercostal nerve block epidermis to human body in using.Perform the operation and rear 4-6 week can disassemble this utility model.Convalescent period is shorter than the buttcover plate in conventional implant into body, and the head of screw that traditional approach protrudes can be avoided to puncture pleura, avoids causing secondary injury.
