Description
Technical field
The present invention relates to the auxiliary positioning field of orthopaedics intersection draw point, particularly relate to a kind of intersection draw point guider for bone surgery.
Background technology
In bone surgery, draw point often need be used to carry out sclerotin and to fix or auxiliary positioning.The draw point that intersects is that a kind of conventional sclerotin is fixed or auxiliary positioning mode, as Cross K-wire or the steinman pin that intersects.But the importing of intersection draw point also exists technical difficulty: when second draw point imports, need to avoid being close to again first draw point simultaneously, even if the doctor that thus clinical experience quite enriches also is difficult to once success, need repeatedly attempts and take the photograph sheet, adjustment entry point and inserting needle direction.For the doctor lacked experience, repeatedly thread a needle unsuccessfully, the destruction of sclerotin can be caused, affect the healing ability of sclerotin, increase the risk of secondary fracture.Repeatedly attempt also extending operating time, increase patient painful, multiple high-new operation is difficult at Grass-roots Hospital.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of draw point guider that intersects, and this guider easily can change adjustment process during second importing of intersection draw point, reduces the destruction to sclerotin, shortens operating time, alleviates patient's misery.
The technical solution adopted for the present invention to solve the technical problems is: provide a kind of draw point guider that intersects, comprise intermediate and chimeric arm, the two ends of described intermediate connect two chimeric arms respectively, described two chimeric arms and intermediate form concave character type structure, the side that concave character type structure centre cross section is close in the upper end of described two chimeric arms has draw point embeded slot, the opposite side that concave character type structure centre cross section is close in center on described intermediate has draw point pilot hole, first corresponding draw point is installed with between described two draw point embeded slots, described draw point pilot hole is installed with second corresponding draw point, described first draw point intersects with second draw point and adjoins and be not in contact with each other.
Described draw point embeded slot is U-shaped half slot.
The groove width of described draw point embeded slot and the diameter of first draw point match.
The thickness of described intermediate is 2-5cm.
A kind of draw point guider that intersects, comprise intermediate and chimeric arm, one end connected embedding arm of described intermediate, described chimeric arm and intermediate form L-type structure, the side that L-type structure centre cross section is close in the upper end of described chimeric arm has draw point embeded slot, the opposite side that L-type structure centre cross section is close in center on described intermediate has draw point pilot hole, described draw point embeded slot is installed with first corresponding draw point, described draw point pilot hole is installed with second corresponding draw point, and described first draw point intersects with second draw point and adjoin and be not in contact with each other.
Described draw point embeded slot is U-shaped half slot.
The groove width of described draw point embeded slot and the diameter of first draw point match.
The width of described chimeric arm is 2-5cm.
beneficial effect
Because technique scheme is used, the present invention compared with prior art has following advantages:
The importing adjustment process of easyization intersection draw point, shorten operating time, structure is simple, easy to operate, economical and practical, easy to utilize.

Detailed description of the invention
Below in conjunction with specific embodiment, set forth the present invention further.Should be understood that these embodiments are only not used in for illustration of the present invention to limit the scope of the invention.In addition should be understood that those skilled in the art can make various changes or modifications the present invention, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the present invention's instruction.
As shown in figs. 1-7, a kind of draw point guider that intersects, comprise intermediate 1 and chimeric arm 2, the two ends of described intermediate 1 connect two chimeric arms 2 respectively, described two chimeric arms 2 form concave character type structure with intermediate 1, the side that concave character type structure centre cross section is close in the upper end of described two chimeric arms 2 has draw point embeded slot 3, the opposite side that concave character type structure centre cross section is close in center on described intermediate 1 has draw point pilot hole 4, first corresponding draw point 6 is installed with between described two draw point embeded slots 3, described draw point pilot hole 4 is installed with second corresponding draw point 7, described first draw point 6 intersects with second draw point 7 and adjoins and be not in contact with each other.
Described draw point embeded slot 3 is U-shaped half slot.
The groove width of described draw point embeded slot 3 and the diameter of first draw point 6 match.
The thickness of described intermediate 1 is 2-5cm.
A kind of draw point guider that intersects, comprise intermediate 1 and chimeric arm 2, one end connected embedding arm 2 of described intermediate 1, described chimeric arm 2 forms L-type structure with intermediate 1, the side that L-type structure centre cross section is close in the upper end of described chimeric arm 2 has draw point embeded slot 3, the opposite side that L-type structure centre cross section is close in center on described intermediate 1 has draw point pilot hole 4, described draw point embeded slot 3 is installed with first corresponding draw point 6, described draw point pilot hole 4 is installed with second corresponding draw point 7, described first draw point 6 intersects with second draw point 7 and adjoins and be not in contact with each other.
