Description
Technical field
The utility model belongs to orthopedic medical device technical field, fixes in specifically a kind of pelvis with reset function
Steel plate.
Background technique
Pelvic fracture is a kind of wound caused via violence extruding, this injury is then common in traffic accident or surprisingly collapses
Caused by collapsing and weighing wounded, and since pelvis is anatomical structure made of as combined by the bone of a variety of kenels, institute in different directions with power
Seriousness of the external impacts of amount in addition to will affect pelvic fracture can also be produced because fracture or dislocation occurs for the bone of different parts
The fracture of raw different kenels, as the stable or basicly stable fracture of pelvic ring, pelvic ring rotate unstable longitudinal stability fracture, bone
The rotation of basin ring and longitudinal unstable fracture.
Existing pelvis internal fixation steel plate is usually a straight steel plate, carries out bending according to the position of patients with fractures and makes,
Then it is fixed by screws in pelvis again.In steel plate installation, need first to be restored fracture with reduction of the fracture device, by bone
Son in situ is broken at folding, then steel plate is placed on the bone after restoring, and then squeezes into positioning spiral shell in screw hole on the steel plate
Nail is fixed.And this kind of mode is used to be difficult to be put into steel plate since reduction of the fracture device can occupy steel plate position when resetting, and in bone
Steel plate is put again squeeze into fracture when positioning screw is fixed and may be displaced again in folding position after resetting.Therefore existing
Steel plate position during operation it is relatively difficult, it is difficult to realization accurately position, it is bad so as to cause surgical effect, to patient's later period
Recovery bring certain influence.
Summary of the invention
The utility model is in view of the shortcomings of the prior art, provide a kind of pelvis internal fixation steel plate with reset function, this kind
It is related on steel plate to have dismountable reduction of the fracture structure, steel plate can be first placed on the bone of the wounded carry out the reduction of the fracture again,
Positioning screw is beaten in the case where bone is in reset state and is supported by resetting structure, then resetting structure is removed, to make
When must perform the operation can precise positioning, so that patient's later period is restored more preferable.
In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals: one kind, which has, to be resetted
The pelvis internal fixation steel plate of function, including the first steel plate along edge on iliopectineal line, from ischial spine extend to iliac fossa and with
First steel plate end connection the second steel plate, between first steel plate and second steel plate middle part between be connected with
The matched third steel plate of pelvis surface curve is provided on first steel plate, second steel plate and the third steel plate
Several location holes are provided with several extensions for crossing iliopectineal line fitting pelvis surface curve, institute on first steel plate
It states and is also equipped with several location holes on extension, be provided with threaded hole on first steel plate and second steel plate, it is described
The resetting structure being detachably connected on threaded hole, the resetting structure include registration arm, and rotation is provided with the in the registration arm
One operating stick, first operating stick lower end are connected with guide sleeve, are equipped with the second operating stick in the guide sleeve, and described second
It is provided with the first spring base in operating stick, the guide sleeve bottom is equipped with second spring seat, first spring base and described the
Spring is provided between two spring bases, second operating stick bottom is provided with drag hook.This kind of pelvis internal fixation steel plate is using
When, steel plate is placed along the curve of pelvis, resetting structure is then loaded onto, to being adjusted reset at os pelvicum fracture, and is adjusting
It is whole it is good after clamped by spring force, guarantee certain positioning, be then in reset state in bone and supported by resetting structure
In the case where beat positioning screw, then resetting structure is removed so that when operation can precise positioning, restore patient's later period
More preferably.
In above-mentioned technical proposal, it is preferred that the registration arm end rotation is provided with externally threaded rotating member, described
The external screw thread of rotating member and the threaded hole cooperate.Made using the structure convenient for disassembly and assembly between registration arm and steel plate.
In above-mentioned technical proposal, it is preferred that first operating stick and second operating stick upper end are provided with hand-held
Portion.Make doctor easier to operate during operation using the structure, it is convenient that push-and-pull operation is carried out to two operating sticks.
The utility model compared with prior art, has the following beneficial effects: this kind of pelvis internal fixation steel plate when in use,
Steel plate is placed along the curve of pelvis, resetting structure is then loaded onto, to being adjusted reset at os pelvicum fracture, and is adjusting
It is clamped later by spring force, guarantees certain positioning, the feelings for being then in reset state in bone and being supported by resetting structure
Condition is lower to beat positioning screw, then resetting structure is removed so that operation when can precise positioning, restore patient's later period more
It is good.
