The utility model in view of the above-mentioned problems, provide it is a kind of in orthomorphia complete osteotomy operation, collection positioning, lead
Orthopedic section of bone plate system being integrated to, ranging provides more accurately osteotomy guiding for clinician.
The purpose of this utility model can be realized by following technical proposals: a kind of orthopedic section of bone plate system, comprising: cut
Bone plate, with osteotomy slot and nail hole；And locating pin, it may pass through the nail hole on the osteotomy plate to fix osteotomy plate.
Preferably, the osteotomy plate is equipped with the osteotomy slot that multiple tracks is parallel to each other, and is equipped with scale marker by per pass osteotomy slot,
The centre of the osteotomy plate is equipped at least two nail hole parallel with osteotomy slot.
It is highly preferred that the osteotomy slot and nail hole are arranged along the length direction of osteotomy plate.
Preferably, the front of the locating pin is equipped with tapping screw thread, and the middle part of locating pin, which is equipped with Bolt-hole fits, to be limited
Stop collar, the tail end of positioning ring with electric tool for connecting.
It is highly preferred that the tail end of the positioning ring is in trigone handle.
It is highly preferred that be smooth rivet nut between the tapping screw thread of the locating pin front and the stop collar in the middle part of locating pin,
The length of the smooth rivet nut is the thickness of osteotomy plate.
It is highly preferred that stop collar in the middle part of the locating pin and be smooth rivet nut between the tail end of locating pin.
Compared with prior art, the utility model is maximum using the compound design for integrating positioning, guiding, ranging
Guarantee quickly going on smoothly for osteotomy operation in degree, improve osteotomy precision, save operating time, obtains satisfied operation effect
Fruit.It specific advantage and has the beneficial effect that:
1, orthopedic osteotomy plate system structure is simple, easy to manufacture；
2, orthopedic section of bone plate system integrates positioning, guiding, distance measurement function, reduces error, easy to operate, function can
It leans on, applicability is wide；
3, osteotomy slot Parallel Design matches osteotomy section more, is more advantageous to the recovery line of force, promotes knitting；
4, according to different demands, single osteotomy plate can complete the osteotomy in different angles with backbone, combine two or more
A osteotomy plate, can complete irregular shape osteotomy；
5, osteotomy plate is using high Intensity Designs such as stainless steel, pure titanium or carbon steels, it is not easy to be lost, work long service life.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of rectangle osteotomy plate.
Fig. 2 is the structural schematic diagram of locating pin.
Component mark is as follows in figure:
1 osteotomy plate
2 osteotomy slots
3 nail hole
4 scales
5 locating pins
51 self-tapping screws
52 stop collars
53 trigone handles.
Specific embodiment
Specific embodiment of the present utility model is described in detail below in conjunction with attached drawing, becomes apparent from those skilled in the art
How ground understanding practices the utility model.Although describing the utility model in conjunction with its preferred embodiment, these
Embodiment only illustrates, rather than limits the scope of the utility model.
Referring to Fig. 1 and Fig. 2, orthopedic section of bone plate system, including osteotomy plate 1 and locating pin 5.
The osteotomy plate 1 is in rectangle, and the high Intensity Designs such as stainless steel, pure titanium or carbon steel can be used.Along length on osteotomy plate 1
Direction offers the osteotomy slot 2 that multiple tracks is parallel to each other, and osteotomy slot 2 can provide guiding role for the power-driven saw of plurality of specifications,
Osteotomy slot 2 is arranged in parallel, so as to parallel osteotomy, wherein it is fixed for being packed into be equipped between most intermediate twice osteotomy slot 2
2 nail hole, 3,2 nail hole 3 of position nail 5 are equally arranged and, nail hole 3 parallel with multiple tracks osteotomy slot 2 along the length direction of osteotomy plate 1
It is opened up perpendicular to 1 plate face of osteotomy plate, so that being not in the problem of locating pin 5 hinders saw blade during osteotomy.Per pass osteotomy slot 2
Side is printed on scale marker 4, can read scale marker 4 in this way to calculate the spacing between osteotomy slot 2.
The front of the locating pin 5 is equipped with tapping screw thread 51, can reach fixed osteotomy by the nail hole 3 on osteotomy plate 1
The purpose of plate 1.The middle part of locating pin 5 is equipped with stop collar 52, and stop collar 52 is for preventing locating pin 5 to be placed in nail hole 3 too far.It is fixed
The tail end of position ring is in 53 shape of trigone handle, can be securely mounted on electric tool.Wherein, the self tapping of 5 front of locating pin
It is smooth rivet nut between the stop collar 52 at 5 middle part of screw thread 51 and locating pin, non-threaded, the length of smooth rivet nut is osteotomy plate 1
Thickness.It is smooth rivet nut between the trigone handle 53 of 5 tail end of stop collar 52 and locating pin at 5 middle part of locating pin, it is non-threaded.
The operating procedure of orthopedic section of bone plate system is as follows:
Step (1) is according to the distance between the angle of operation plan design osteotomy and different osteotomy position, in operation bone
Osteotomy plate 1 is placed on the outside of cortex bone by osteotomy site needed for cortical exterior surface marks and direction, and osteotomy plate 1 passes through locating pin 5
Via nail hole 3 and skeletal fixation.Specifically, the trigone handle 53 of 5 tail end of locating pin is connect with electric tool, passes through electronic work
Tool pierces the tapping screw thread 51 of 5 front of locating pin in backbone through nail hole 3, until the stop collar 52 at 5 middle part of locating pin is stuck in nail
On hole 3.
After step (2) determines that osteotomy direction, angle, distance meet operation plan design requirement, by the osteotomy on osteotomy plate 1
Slot 2 guides power-driven saw to implement to orient osteotomy, the parallel osteotomy of spacing, wherein the spacing between osteotomy slot 2 is according to corresponding
Scale marker 4 read, calculate.
If the osteotomy mode of pre-operative surgical conceptual design be wedge osteotomy or irregular shape osteotomy, more according to design scheme
The position for changing locating pin 5 completes osteotomy operation by multiple circulation step (1) and step (2).
It should be pointed out that can also have a variety of transformation and the implementation of remodeling for the utility model through absolutely proving
Scheme, it is not limited to the specific embodiment of above embodiment.Above-described embodiment as just the utility model explanation, and
It is not limitations of the present invention.In short, the protection scope of the utility model should include those for ordinary skill
It obviously converts or substitutes and retrofit for personnel, and be determined by the appended claims.
