Description
Technical field
The utility model relates to a kind of during surgery for carrying out minimally invasive reset to the intra-articular collapsed fracture block of tibial plateau
Device, belong to orthopedic medical device technical field.
Background technique
Fracture of tibial plateau is common intra-articular fracture in clinic, it is common by high-energy damage in, young people.
Since fracture complex shape is changeable, clinical treatment is more intractable.The purpose for the treatment of for tibial plateau fracture be restore articular surface it is smooth and
The lower limb line of force, avoids the occurrence of the long term complications such as postoperative traumatic arthritis, anchylosis at strong fixed sclerite.Operation is controlled
The committed step for treating fracture of tibial plateau is resetted to the sclerite of displacement.Traditional incision resetting technique is that acquisition is good
Surgical field of view, it is often necessary to a wide range of exposure knee joint peripheral soft tissue.For fracturing on the outside of Schatzker II and type III,
There is scholar to propose to cut lateral meniscus first half sufficiently to expose articular surface；It is flat for the shin bone for merging outside back displacement
Platform fracture, Pires propose to cut off fibula proximal end to facilitate outside sclerite after reset.Although these operations can be reset strap
It facilitates, but the risks such as postoperative soft tissue adhesion, infection of incisional wound and neurotrosis greatly improve.
The development trend of intra-articular fracture is minimally invasive reset at present, with effective protection fracture surrounding soft tissue.It is current minimally invasive
Maximum problem existing for operation method is that minimally invasive reset intra-articular fracture can only lead to drill too far away from fracture site,
The tunnel formed by drilling reaches and carries out jack-up reset below sclerite, but minimally invasive jack-up device used at present is oblique sets
Entering osseous tunnel, implantation site is separate to collapse bone block, while bone window aperture position will cause tibial shaft bone defect far from knee joint,
Shin bone overall stability is seriously affected, also needs long bone plate to be supported fixation after reset, is otherwise easy to appear iatrogenic
Fracture of shaft of tibia.The bone plate additionally placed will cause the waste of additional operative incision, soft tissue injury and medical resource, make
The complication rates such as postoperative wound infection and dysfunction improve, and making patients' medical burden, this is one urgently to be resolved
Problem.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of minimally invasive restorer of tibial plateau collapsed fracture block, this
The minimally invasive restorer of kind can use cross drilling and carry out sufficiently jacking up reset to bone block is collapsed, and bone defect can be carried out after the completion of reset
Bone grafting can also be screwed into screw support sclerite in screw way, accomplish not increase any additional injuries.
The technical solution for solving above-mentioned technical problem is:
A kind of minimally invasive restorer of tibial plateau collapsed fracture block, it includes reseting disk, mandril, handle, and reseting disk is disk,
The diameter of reseting disk and the diameter of minimally invasive drilling match, and the front end of mandril is connected with the bottom surface of reseting disk, the rear end of mandril
It is connected with handle, mandril is flexible long rod, and mandril is made by high molecular material or spring, and the length of mandril is greater than micro-
Create the length of drilling.
The above-mentioned minimally invasive restorer of tibial plateau collapsed fracture block, the mandril are the cylindrical bar of polytetrafluoroethylene (PTFE) production
Body, the diameter of cylindrical rod body are 3.5-4.5mm, and the length of cylindrical rod body is greater than the length of minimally invasive drilling.
The above-mentioned minimally invasive restorer of tibial plateau collapsed fracture block, the mandril are the long spring of elastic wire winding, spring
Outer diameter be 4-4.2mm, the length of spring is greater than the length of minimally invasive drilling.
The beneficial effects of the utility model are:
The utility model is that tibial plateau collapses the pioneering of bone block reset mis instruments, solves current minimally-invasive treatment shin bone
Platform, which collapses, to be caused tibial shaft bone defect, seriously affects the problem of shin bone overall stability present in bone block reattachment surgery, be
Minimal invasive operation tibial plateau collapses bone block reset and opens new approach.
The utility model structure is simple, easy to use, also needs long bone plate to be supported fixation after avoiding reset,
Reduce additional surgical notch and soft tissue injury, greatly reduce the generation of the complication such as postoperative wound infection and dysfunction,
To simplify medical procedure, medical resource has been saved, has alleviated patient medical burden.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the utility model；
Fig. 2 is another structural schematic diagram of the utility model.
Mark in figure as follows: shin bone 1 collapses bone block 2, minimally invasive drilling 3, reseting disk 4, mandril 5, handle 6.
Specific embodiment
The utility model is made of reseting disk 4, mandril 5, handle 6.
It is shown in figure, reseting disk 4 is disk, and the diameter of reseting disk 4 and the diameter of minimally invasive drilling 3 match, reseting disk 4
Bottom surface is connected with the front end of mandril 5, and the rear end of mandril 5 is connected with handle 6.
It is shown in figure, mandril 5 is flexible long rod, and mandril 5 is made by high molecular material or spring.Mandril 5 it is straight
Diameter is 3.5-4.5mm, and the length of mandril 5 is greater than the length of minimally invasive drilling 3.The effect of mandril 5 is to push reseting disk 4 to move forward
Dynamic, when reseting disk 4 reaches the corner of minimally invasive drilling 3, mandril 5 can be bent, and reseting disk 4 is turned to propulsion upwards, is reached
The effect of bone block 2 is collapsed to jack-up.
In order to enable mandril 5 to push reseting disk 4 mobile, mandril 5 must have certain rigidity, and be able to carry out curved
Folding, keeps this rigidity in the case where bending, mobile to continue to press on reseting disk 4, therefore mandril 5 selects following two knot
Structure.
A kind of structure is the cylindrical rod body that mandril 5 is made by polytetrafluoroethylene (PTFE), and the mandril of this material production has one
Fixed rigidity, and this rigidity can be kept in that case of ben.
Another structure is that mandril 5 is the long spring of elastic wire winding, and this long spring is the prior art, using wide
General, the instrument of dredging drainpipe in the market has the long spring of various different sizes, for promoting in curved pipeline in the wrong.This reality
Outer diameter with novel used spring is 4-4.2mm, and the length of spring is greater than the length of minimally invasive drilling 3.
The application method of the utility model is as follows:
Firstly, determining that tibial plateau collapses 2 position of bone block under fluoroscopy, horizontal direction at 0.5cm is being collapsed below bone block 2
With 4.5mm diameter screw bit bore, it is located just at minimally invasive drilling 3 and collapses 2 lower section of bone block, take out drill bit；
Then, the reseting disk 4 of restorer front end is placed in along minimally invasive drilling 3 in the horizontal direction and collapses 2 lower section of bone block, perspective
After position is satisfied, mandril 5 is pushed forward using handle 6, and the reseting disk 4 of 5 front end of mandril will collapse bone block 2 and jack up upwards, reset
After satisfaction, mandril 5 and reseting disk 4 are exited；
Bone grafting cancellous bone is placed in minimally invasive drilling 3, reseting disk 4 is reentered into minimally invasive drilling 3, handle 6 is used
Mandril 5 and reseting disk 4 are pushed forward, and bone grafting is pushed to the bone defect for collapsing and being formed after bone block 2 jacks up by reseting disk 4 with cancellous bone
Locate, progress bone grafting, after bone grafting, withdraws from restorer；
Finally, being screwed into the fixed plant bone mass of screw along minimally invasive drilling 3, operation terminates, and plate fixation is not necessarily to, without new increase and lose
Wound.
