Description
Technical field
The utility model is related to a kind of sclerotin lesion clean-out assemblies, belong to the field of medical instrument technology, are particularly suitable for stock
Head necrosis Minimally Invasive Surgery.
Background technology
Caput femoris necrosis is also known as ischemic femoral head necrosis, is a kind of common disease, and pathomechanism is bone tissue ischemic,
I.e. since the inside and outside pathogenic factor of various bones causes bone tissue nutritional blood flow to reduce, rete vasculosum is pressurized or outflow vein obstruction in bone,
Cause local blood supply obstacle, severe patient that can cause bone tissue ischemic necrosis.It is generally deposited in caput femoris necrosis Minimally Invasive Surgery at present
The problem of be, due to the limitation in minimally invasive channel, it is difficult to necrosis region is fully erased, it is relatively low to ultimately cause success rate of operation.
Chinese utility model patent CN203303107U discloses a kind of abrasion drill for orthopedic operation, the axis runout of drilling rod
The axis of bistrique forms a kind of eccentric abrasive drilling of drilling rod and bistrique bias, can cut removal inside bone necrosis bone tissue
Range be significantly larger than the diameter of bistrique, be applicable to the minimally invasive lower operation for repairing downright bad bone tissue.But, however it remains cutting
The problem that range is fixed and is limited.
Invention content
To solve the above technical deficiency, the utility model provides a kind of sclerotin lesion clean-out assembly, devises partially
The operating mode that the revolution that reduction is bored is combined with rotation can selectively expand lesion cutting range, it is bad that femoral head can be improved
The success rate of dead Minimally Invasive Surgery.
The technical solution of the utility model is as follows：A kind of sclerotin lesion clean-out assembly, including intensive and eccentric bistrique, institute
It includes intensive bar to state intensive, and the tail end of the intensive bar is provided with one group of revolution adjustment hole, and the bias bistrique includes
Bistrique and drilling rod, the axis of the drilling rod and the axis runout of bistrique, the drilling rod are clearance fits with revolution adjustment hole.
The technical solution of the utility model further includes：The center of circle of the revolution adjustment hole and the tail end center of intensive bar are not
It overlaps.
The technical solution of the utility model further includes：The quantity of the revolution adjustment hole is three, three revolution adjustment holes
The center of circle be triangularly arranged.
The technical solution of the utility model further includes：The quantity of the revolution adjustment hole is two, two revolution adjustment holes
The line in the center of circle is obliquely installed.
The technical solution of the utility model further includes：The intensive bar is connected with intensive handle, on intensive handle
Portion is provided with the mounting hole coordinated with intensive bar.
The technical solution of the utility model further includes：The intensive bar and intensive handle laser welding are integral.
The utility model has the beneficial effects that：The clean-out assembly being made of eccentric bistrique and intensive is designed, first with
The eccentric setting of eccentric bistrique can make bistrique relative to drilling rod bias, and then can expand the radius of turn of bistrique, and expansion is cut
Secondly the range cut one group of bias bistrique revolution adjustment hole is arranged on intensive, entire drilling rod can be made relative to intensive
Bias even if drilling rod can expand radius of turn relative to minimally invasive channel bias on the basis of drilling rod, and then expands cutting model
It encloses, finally, using the composite structure of drilling rod bias and bistrique bias, even if final functional component bistrique shows revolution and oneself
Turn the operating mode combined, can selectively expand lesion cutting range, it can be ensured that necrosis region remove it is clean, improve bone grafting at
Probability living, and then improve the success rate of caput femoris necrosis Minimally Invasive Surgery.

Specific implementation mode
Below in conjunction with attached drawing, by embodiment, the utility model is described in further detail.
As shown in Figure 1 to Figure 3, a kind of sclerotin lesion clean-out assembly of the utility model, including intensive 1 and eccentric bistrique
2, eccentric bistrique 2 includes bistrique 21 and drilling rod 22, also, the axis runout of the axis of drilling rod 22 and bistrique 21.
Intensive 1 includes intensive bar 12, and the tail end of intensive bar 12 is provided with one group of revolution adjustment hole 13, wherein
Tail end refers to one end far from treatment patient.When operative treatment, the drilling rod 22 of eccentric bistrique 2 is inserted into revolution adjustment hole 13,
Make drilling rod 22 and revolution 13 clearance fit of adjustment hole.
Specifically, the center of circle and the tail end center of intensive bar 12 of revolution adjustment hole 13 are misaligned, i.e. the two eccentric setting.
As shown in Figure 1, in the embodiments of the present invention one, the quantity of revolution adjustment hole 13 is three, three adjustment holes 13 that revolve round the sun
The center of circle is triangularly arranged.As shown in figure 4, in the embodiments of the present invention two, the quantity of revolution adjustment hole 13 is two, two
The line in 13 center of circle of a revolution adjustment hole is obliquely installed.
In order to facilitate use, intensive 1 further includes having intensive handle 11, is provided with and adds on 11 top of intensive handle
The mounting hole of 12 cooperation of strong device bar, by intensive bar 12 after mounting hole loading, using laser welding by intensive bar 12 with
Intensive handle 11 is integrally welded.
When operative treatment, according to the lesion range of patient, eccentric bistrique 1 is inserted into the revolution adjustment hole 13 of different location
In, make drilling rod 22 that there is different eccentric distances relative to minimally invasive channel, and then make drilling rod 22 that there is different radiuss of turn, it is real
The necrosis region cutting of existing different range.
The above is only the preferred embodiment of the utility model, not does limit in any form to the utility model
System, done all any modification, equivalent and improvement etc., should be included in this reality within the spirit and principle of the utility model
Within novel protection domain.
