Abstract
The utility model belongs to field of medical technology, discloses a kind of long bone of limbs metaphysis and takes bone object, the 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, and trepan in the inner core end contact, middle ring sawdust end is arranged to zigzag inside the outer sleeve.The utility model 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 utility model belongs to field of medical technology more particularly to a kind of long bone of limbs metaphysis takes bone object.
Background technique
During fracture operation, it is sometimes desirable to carry out bone grafting operation for bone tissue and be 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 existing bone grafting operation the problem is that: or from autologous ilium take bone or using homogeneous allogenic bone
Or artificial bone, there are certain advantage and disadvantage, takes autologous ilium that need to increase patient trauma, and use homogeneous allogenic bone or artificial bone can
There can be rejection.Bone is taken using the tool of the utility model, takes out complete sclerotin under the premise of not making patients damage,
Facilitate and carry out autologous bone bone grafting operation, to improve clinical efficacy.
Summary of the invention
In view of the problems of the existing technology, the utility model provides a kind of long bone of limbs metaphysis and takes bone object.
The utility model is realized in this way the long bone of limbs metaphysis takes bone object to be provided with outer sleeve；The outer sleeve
Inside is equipped with inner core, and the length of inner core is suitable with outer sleeve, trepan in the inner core end contact, middle ring sawdust end
It 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 such inner core can be retracted into
In middle trepan, guarantee takes bone to carry out along guide pin direction, and conveniently takes bone.Latter half is designed to that both sides are slotted, and takes convenience after bone
Bone item is obtained, and helps to exit inner core.
The advantages of the utility model and good effect are as follows: it can perfectly be matched with intramedullary nail system, avoid solid failure,
The complete sclerotin of long bone of limbs metaphysis can be taken out simultaneously, facilitate bone grafting, reduce the disunion of fracture end, avoid taking autologous ilium or
Homogeneous allogenic bone or the manpower bone establishes a bone mitigate patient's pain and financial burden.
Detailed description of the invention
Fig. 1 is the structural schematic diagram that long bone of limbs metaphysis provided by the utility model takes bone object；
Fig. 2 is the structural schematic diagram for the middle trepan that long bone of limbs metaphysis provided by the utility model takes bone object；In figure: 1,
Outer sleeve；2, inner core；3, middle trepan.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, with reference to embodiments, to this
Utility model is further elaborated.It should be appreciated that specific embodiment described herein is only to explain that this is practical new
Type is not used to limit the utility model.
The utility model combination clinical practice takes bone tool to want hand from four limbs metaphysis using same incision using patent
The position of art is drawn materials nearby, can be taken off complete sclerotin while expanding marrow, is avoided taking bone from other positions or is applied other bone graftings
Material, to alleviate the damage and financial burden of patient.
The structure of the utility model is explained in detail with reference to the accompanying drawing.
As shown in Figure 1, long bone of limbs metaphysis provided by the embodiment of the utility model takes bone object to be provided with outer sleeve 1；Institute
It states and inner core 2 is installed inside outer sleeve 1,2 length of inner core and outer sleeve 1 are suitable, trepan 3 in 2 end of the inner core contact,
3 end of middle trepan is arranged to zigzag.
As the preferred embodiment of the utility model, 1 diameter of outer sleeve is matched with corresponding intramedullary nail size.
As the preferred embodiment of the utility model, 2 length of inner core and outer sleeve 1 are consistent, and diameter is small compared with outer sleeve 1
1mm。
As the preferred embodiment of the utility model, middle 3 length of trepan is twice of outer sleeve 1, and diameter is less than outer
The about 1mm of sleeve 1, such inner core 2 can be retracted into middle trepan 3, and guarantee takes bone to carry out along guide pin direction, and conveniently takes bone.It is latter half of
Divide and be designed to that both sides are slotted, facilitates acquisition bone item after taking bone, and help to exit inner core 2.
Working principle of the utility model is: this is made of three-piece from producing bone object, respectively outer sleeve 1, middle trepan 3 and
Inner core 2 forms, and 1 diameter of outer sleeve matches with intramedullary nail size, and middle trepan 3 and 2 diameter of inner core respectively subtract 1mm compared with outer sleeve, in this way
Can be all linked with one another, device assembling is finished, the position for needing to take bone is placed in, the top connection electric drill or handle of middle trepan 3 bore
Enter appendicular skeleton metaphysis, then carries out taking bone into metaphysis by trepan 3 in guide pin insertion inner core 2 and process.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
