Description
Technical field
This utility model relates to technical field of medical instruments, particularly relates to a kind of medical Ilium bone taking device.
Background technology
It is a kind of operation method very conventional in Orthopedic Clinical that autologous ilium is transplanted.Its indication includes fracture
Union of fracture, filling bone defects, malformation correction and arthrodesis etc. are promoted when disunion or delayed union.
The effect of its treatment nonunion is better than other bone graft substitute, is the gold mark for the treatment of nonunion
Accurate.Ilium takes the method for bone and selects generally according to purpose and the quantity of required bone of bone collection.Typically can divide
For: the full plate of ilium takes bone, including three layers of cortex, is fabricated to rectangle or wedge shape, for the knot in Cranial defect district
Structure supports；Half plate takes bone and thin layer lamellar takes bone.Rear both take out after be generally trimmed to matchstick shape bone bar or
Skeletal grain implants fracture gap and surrounding, to promote union of fracture.It is to leave over ilium that ilium takes the main shortcoming of bone
The discomfort that the irreversible external defects in Gu Gong district and Cranial defect cause.Traditional method is cut along crista iliaca, stripping
Adhere to from inner and outer plates muscle, cut monoblock ilium or thin layer osteocomma with osteotome, then be trimmed to matchstick shape bone bar.
Leave over bigger ilium defect area after taking and cause patient pain and discomfort.For reducing the ilium damage for district
Evil, the transplanting ilium needed for simultaneously easy taking out.Researching and developing a kind of medical Ilium bone taking device is that this area is current
Having needed of task.
Summary of the invention
Present invention aim at the medical ilium providing a kind of simple in construction, incision easy to use, little to take bone
Bone takes bone object.
In order to achieve the above object, this utility model following structure of employing: a kind of medical Ilium bone taking device, by
Hammer cap, sleeve, handle and jumper bar composition, be characterized in: hammer cap is rustless steel short cylinder, and top is big
Circular bosses in cylinder diameter；Rustless steel upper cartridge has the circumference boss greater diameter than sleeve diameter,
One section of sleeve on boss is the long sleeve of smooth outer surface with the sleeve under external screw thread, boss, bottom circle
Circumference contract is polished into orifice, and middle handle is the cylinder of female thread, the protruding horizontal stroke of cylinder lateral symmetry
Beam, constitutes in-line handle, the cooperation rotation of in-line handle threads is tightened in the upper cartridge end of thread and is located
On circumference boss, in the short cylinder of hammer cap coordinates the cylinder inserting middle handle；The knot of rustless steel jumper bar
Structure is identical with hammer cap, and its cylindrical length is then more than length sleeve, and replaceable hammer cap passes in handle
Insert in sleeve after the cylinder in portion, thus constitute a kind of medical Ilium bone taking device.
Long sleeve smooth under sleeve boss described above is circular cross-section, a diameter of 8-12mm.
Long sleeve smooth under sleeve boss described above is square-section, the length in cross section × wide=12 × 8mm.
When this utility model uses, the Ilium bone taking device sleeve orifice end assembled is placed on ilium, one
Holding tight in-line handle, another hands hammer hammering Ilium bone taking device hammers cap into shape, and the percussion power of generation is by ilium
Bone takes the long sleeve of bone object and throws ilium into, and the ilium that long sleeve orifice end-grain cutting is cut off is filled with along with sleeve income
Enter in long sleeve, after long sleeve enters desired depth, extract Ilium bone taking device, cap will be hammered into shape from middle handle
Cylinder in take out, then jumper bar is inserted, hit with a hammer jumper bar top, is ejected by the ilium in long sleeve
Long sleeve, obtains required ilium.
Owing to using said structure, this utility model has the beneficial effect that it is first micro-wound bone taking,
Little otch, only need to cut skin subcutaneous tissue, it is not necessary to peel off ilium hone lamella muscle, greatly reduces operation and damages
Wound, reduces amount of bleeding, shortens operating time, reduces postoperative ilium for district's pain degree.Furthermore it is to keep
Ilium configuration structure, do not leave over irreversible Cranial defect, it is to avoid the permanent ilium that conventional method is left over
Gu Gong district is damaged.
This utility model kind simple in construction, easy to use, mini-invasive incision take bone, have reached goal of the invention.

Detailed description of the invention
This utility model is described in detail in detail below in conjunction with the accompanying drawings, can be seen that structure of the present utility model from Fig. 1-Fig. 5,
A kind of medical Ilium bone taking device, is made up of hammer cap 1, sleeve 3, handle 2 and jumper bar 4, and hammer cap 1 is not
Rust steel short cylinder, top is the circular bosses more than cylinder diameter；Stainless sleeve 3 top has always
Footpath is more than the circumference boss of sleeve 3 diameter, and one section of sleeve 3 on boss is with the set under external screw thread, boss
Cylinder 3 is the long sleeve 3 of smooth outer surface, and long sleeve 3 is circular cross-section, a diameter of 10mm, bottom circumference
It is polished into orifice to contract, is the cylinder of female thread in the middle part of handle 2, the protruding horizontal stroke of cylinder lateral symmetry
Beam, constitutes in-line handle 2, in-line handle 2 threaded engagement is rotated and is tightened in sleeve 3 top screw thread
End is seated on circumference boss, in the short cylinder of hammer cap 1 coordinates the cylinder inserted in the middle part of handle 2；Stainless
The structure of steel drift bar 4 is identical with hammer cap 1 structure, and its cylindrical length, can then more than the length of sleeve 3
Replace after hammer cap 1 passes the cylinder in the middle part of handle 2 and insert in sleeve 3, thus constitute a kind of medical ilium and take
Bone object.
Above-described embodiment, as a example by circular cross-section sleeve, describes structure of the present utility model in detail, it is also possible to will
Long sleeve changes the square-section sleeve of length × wide=12 × 8mm into, selects to use according to the needs taking bone.
