Description
Technical field
The utility model belongs to medical instruments field, and in particular to a kind of PH bone plate.
Background technology
Proximal humeral fracture is a kind of common classification of fracture, and external document mostly thinks its incidence 4%～5%,
Wherein 80%～85% is that, without displacement or slight shift fracture, 15%～20% is displacement fracture, needs mostly operative treatment.The upper arm
Proximal bone fracture can occur in any age bracket, but be most commonly in gerontal patient, and its generation is substantially relevant with osteoporosis, this
Outward, also it is more common in the wound of between twenty and fifty high-energy.With the intensification recognized for proximal humeral fracture, its treatment method is not yet
Disconnected development.
As proximal humeral fracture is complex, its treatment still suffers from many problems.Wherein most auxiliary treatment needs
PH bone plate, and multiple screw holes are typically arranged in plate face with mounting screw, screw hole inwall in the axial direction
It is upper that elongated internal thread is set；After patients ' recovery, when removing bone plate, the soft tissue on cortex of bone surface often grows into screw
On screw thread on the inside of hole；As thread surface product is big and many thread grooves that gather, therefore the soft tissue attachment on cortex of bone surface
Area and adhesive force are larger, are difficult to remove；The later stage rehabilitation of patient can be affected after even removing.
Further, since multiple screws screw in humerus by bone plate, the screw hole of existing bone plate is circular port, respectively
Screw is fixed and recovers to grow up with movement of patient or sclerotin, and bone plate has one in the longitudinal direction and pulls active force；Cause
This, under long term, screw can apply a compression to humerus, affect sclerotin to recover, while can also increase patient's throe.

Near end plate lateral surface, the second smooth hole section is near end plate medial surface.
As movement of patient or sclerotin recover, after each screw fastening, can be by long round tube hole with humerus rehabilitation microcosmic
Elongation and carry out axial displacement to the end of tailgate, will not can apply compression to humerus, beneficial to sclerotin recover, patient comfort
Degree is high.Additionally, after trip bolt, the first smooth hole section of close end plate medial surface and the second unthreaded hole section surface are smooth, cortex of bone table
The soft tissue in face is difficult apposition growth；During postoperative dismounting PH bone plate of the present utility model, cortex of bone surface is not had
Soft tissue pull, remove very convenient simple, beneficial to the rehabilitation in patient's later stage.
Specifically, rounding is respectively provided with the aperture of the first smooth hole section and the second smooth hole section；Cortex of bone can further be prevented
The soft tissue attachment hole wall growth on surface, it is convenient to remove.
Specifically, some bar-shaped troughs are all evenly equipped with the plate thickness surface of bone plate both sides in the longitudinal direction, remove synthetism
During plate, bone plate can be pried open by bar-shaped trough using instrument, remove convenient.
Further, two bar-shaped troughs are equipped with the plate thickness surface of bone plate both sides in the longitudinal direction, and in homonymy
Plate thickness surface on, bar-shaped trough is located on end plate, and another bar-shaped trough is located at tailgate；The length direction of each bar-shaped trough with connect
The length direction of hone lamella is parallel.The utility model can be levered up on the bar-shaped trough at bone plate two ends simultaneously simultaneously, prevent one end from prizing
After rising, other end compressing humerus is damaged.
Further, the 1～1.8mm of groove width of bar-shaped trough, 1～1.5mm of groove depth, are applicable to the bone plate of different size.
Preferably, the surface roughness of the first smooth hole section and the second smooth hole section is Ra1.6, and surface is smooth, is less susceptible to attachment
The soft tissue on humerus cortex of bone surface.
A kind of beneficial effect of PH bone plate of the present utility model is：
1. as movement of patient or sclerotin recover, after each screw fastening, can be by long round tube hole with humerus rehabilitation microcosmic
On elongation and carry out axial displacement to the end of tailgate, will not can apply compression to humerus, beneficial to sclerotin recover, Bing Renshu
It is moderately high；
2., after trip bolt, the first smooth hole section of close end plate medial surface and the second unthreaded hole section surface are smooth, cortex of bone table
The soft tissue in face is difficult apposition growth；During postoperative dismounting PH bone plate of the present utility model, cortex of bone surface is not had
Soft tissue pull, remove very convenient simple, beneficial to the rehabilitation in patient's later stage.
