Abstract
The invention belongs to field of medical technology, discloses a kind of long bone of limbs metaphysis and take bone object, the long bone of limbs metaphysis that bone object is taken to be provided with outer sleeve；Inner core is installed, the length of inner core is suitable with outer sleeve, and trepan in the inner core end contact, middle ring sawdust end is arranged to zigzag inside the outer sleeve.The present invention can be matched perfectly with intramedullary nail system, avoid solid failure, can be taken off the complete sclerotin of long bone of limbs metaphysis, facilitate bone grafting, the disunion for reducing fracture end avoids taking autologous ilium or homogeneous allogenic bone or the manpower bone establishes a bone, mitigates patient's pain and financial burden.
Description
Technical field
The invention belongs to medical auxiliary apparatus technical fields more particularly to a kind of long bone of limbs metaphysis to take bone object.
Background technology
Currently, the prior art commonly used in the trade is such：
During fracture operation, it is sometimes desirable to carry out bone grafting operation and bone tissue is transplanted to bone defects, need in patient body
The position reinforced or merged.Due to bone source difference, it is divided into autologous bone transplanting and homogeneous bone transplantation.Autologous bone transplanting is general
Bone need to be taken at patient itself ilium position, for the bone grafting operation without rejection, effect is preferable, but causes certain wound to patient simultaneously
Wound, and resource is limited, some patientss one-stage operation, which has been gone, takes self-iliac bone grafting art, if thinking revision procedure again, is bound to cause
The difficult situation of bone is nowhere taken, if taking bone from other positions by force, is easy the damage of making patients.
In conclusion problem of the existing technology is：
(1) it in bone grafting operation, takes autologous ilium that need to increase patient trauma, and homogeneous allogenic bone or artificial bone is used to be easy
Generate rejection.
(2) it has gone the patient for taking self-iliac bone grafting art, when needing repeat surgery, can nowhere take bone.
Invention content
In view of the problems of the existing technology, the present invention provides a kind of long bone of limbs metaphysis to take bone object, in conjunction with clinic
It is practical, using same incision, draws materials nearby from the position that four limbs metaphysis to be performed the operation, can be taken off complete bone while expanding marrow
Matter avoids taking bone from other positions or applies other bone-grafting materials, to alleviate the damage and financial burden of patient.
The invention is realized in this way a kind of long bone of limbs metaphysis takes bone object to be provided with outer sleeve；
Inner core is installed, the length of inner core is suitable with outer sleeve inside the outer sleeve；
Trepan in the inner core end contact, middle ring sawdust end is arranged to zigzag.
Further, the outer sieeve diameter is matched with corresponding intramedullary nail size.
Further, the length of inner core is consistent with outer sleeve, diameter 1mm small compared with outer sleeve.
Further, the middle trepan length is twice of outer sleeve, and diameter is less than outer sleeve 1mm, and inner core can be retracted into middle ring
In saw, guarantee takes bone to be carried out along guide pin direction, and conveniently takes bone.Latter half is designed to that both sides are slotted, and facilitates acquisition after taking bone
Bone item, and help to exit inner core.
Another object of the present invention is to provide the application method that a kind of long bone of limbs metaphysis takes bone object, the four limbs are long
It is that outer sleeve is positioned over to the position for needing to take bone that bone metaphysis, which takes the application method of bone object, the top connection electric drill of middle trepan or
Middle ring sawdust end is pierced appendicular skeleton metaphysis, then by handle by the rotation of middle trepan using the sawtooth at middle ring sawdust end
Trepan enters metaphysis and carries out taking bone during guide pin s is inserted into inner core and is passed through.
In conclusion advantages of the present invention and good effect are：
The present invention can be matched perfectly with intramedullary nail system, avoid solid failure, can take out the dry epiphysis of long bone of limbs simultaneously
Complete sclerotin is held, bone grafting is facilitated, reduces the disunion of fracture end, avoids that autologous ilium or homogeneous allogenic bone or artificial bone is taken to plant
Bone mitigates patient's pain and financial burden.
Description of the drawings
Fig. 1 is the structural schematic diagram that long bone of limbs metaphysis provided in an embodiment of the present invention takes bone object；
Fig. 2 is the structural schematic diagram for the middle trepan that long bone of limbs metaphysis provided in an embodiment of the present invention takes bone object；
In figure：1, outer sleeve；2, inner core；3, middle trepan.
Specific implementation mode
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to embodiments, to the present invention
It is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not used to
Limit the present invention.
As shown in Figure 1, long bone of limbs metaphysis provided in an embodiment of the present invention takes the bone object to include：Outer sleeve 1, inner core 2, in
Trepan 3.
Inner core 2 is installed inside outer sleeve 1,2 length of inner core is suitable with outer sleeve 1, trepan 3 in the contact of 2 end of inner core, in
3 end of trepan is arranged to zigzag.
As a preferred embodiment, 1 diameter of outer sleeve is matched with corresponding intramedullary nail size.
As a preferred embodiment, 2 length of inner core is consistent with outer sleeve 1, and diameter is compared with 1 small 1mm of outer sleeve.
As a preferred embodiment, 3 length of middle trepan is twice of outer sleeve 1, and diameter is less than the about 1mm of outer sleeve 1, this
Sample inner core 2 can be retracted into middle trepan 3, and guarantee takes bone to be carried out along guide pin direction, and conveniently takes bone.Latter half is designed to that both sides are opened
Slot facilitates acquisition bone item after taking bone, and helps to exit inner core 2.
The present invention is made of three-piece, and 1 diameter of outer sleeve is matched with intramedullary nail size, and middle trepan 3 and 2 diameter of inner core are relatively outer
Sleeve respectively subtracts 1mm, in this way can be all linked with one another, and device assembling is finished, the position for needing to take bone, the top of middle trepan 3 are positioned over
Electric drill or handle are connected, appendicular skeleton metaphysis is pierced, trepan 3 enters metaphysis during guide pin is then inserted into inner core 2 and is passed through
It carries out taking bone.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement etc., should all be included in the protection scope of the present invention made by within refreshing and principle.
