Abstract
The utility model relates to a supporting rod, in particular to a supporting rod embedded in thighbone. The utility model aims at providing a supporting rod which is embedded in the thighbone, is beneficial to restoring and rebuilding the necrotic thighbone and supports the sunken cartilage shell. The supporting rod is characterized in that the rod body is a hollow cylinder; the external wall of the tail part of the rod body is provided with a spiral thread and is internally provided with an internal hexagonal hole that is internally provided with a guide needle hole; the tail part of the rod body is screwed with the rod head; and the top of the rod body is provided with a guide needle hole that is concentric to the tail part of the rod body. The supporting rod is used for the embedded treatment in the necrotic thighbone.
Description
Technical field:
This utility model relates to a kind of support stick, is specially adapted to the placement in the treatment after the femur head necrosis.
Background technology:
Existing have two big classes to what the treatment behind the femoral head early metaphase ischemic necrosis was adopted clinically: protect hip and treat and artificial full hip-joint replacement.The first kind: the treatment of precious hip comprises: from body band blood vessel periosteum lobe move, anastomosis of blood vessel from the body fibula transplant, the memorial alloy supporter is implanted, the titanium net implants that (support force is not enough), allograph bone cage are implanted, the tantalum support stick is implanted; More than protect in the technology of hip treatment early metaphase femur head necrosis the most definitely with tantalum support stick implanted treatment, but owing to cost an arm and a leg, the later stage is taken out tantalum support stick difficulty during artificial hip joint replacing.Second class: though Replacement of Hip Joint is a kind of definite effective method to the treatment of Avascular Necrosis Of Femur Head, but for early stage patient, still there are problems, no matter recurrent height, bone resorption, osteanabrosis, Periprosthetic infection, prosthetic loosening, sinking, prosthese handle fracture, lower limb pain etc. is bone-cement type artificial limb or none-cement type prosthese, and the mortality of osteonecrosis patient row total hip joint is the joint replacement due to the other reasons all.
Summary of the invention:
Task of the present utility model is to propose a kind of femur head necrosis reconstruction that helps, a kind of support stick of inserting in the femoral head that the cartilage shell that will subside supports.Task of the present utility model is finished like this, it is characterized in that: barred body is that hollow is cylindric, on the afterbody outer wall of barred body screw is arranged, in interior hexagonal hole is arranged, a guide pinhole is arranged in the hexagonal hole, the barred body afterbody all is to screw with caput to combine, and one and the concentric guide pinhole of barred body afterbody are arranged at the top of caput.The long 7mm of screw on the barred body head outer wall.On the barred body afterbody to be external screw thread with female thread in the caput screw combines.The material that support stick is selected for use is a titanium alloy.The utlity model has following effect: have the cartilage of subsiding shell enabling capabilities, can select different caput combinations according to capital length, to reach the support of desired site, the same with the core decompression bone grafting operation, the side's of falling otch approach greatly slightly through the femoral head outside, operation wound is little, and is little for destroying to the blood of femoral neck, helps femur head necrosis district reconstruction.The tunnel passes along the neck of femur longitudinal axis, and the cortical bone around the neck of femur is not had destruction, can avoid fracture of femoral neck; (3) medium pore of support stick can communicate with the hip joint chamber, carries out the articular cavity flushing; (4) its caput is a smooth surface, and diameter is than the little 1mm of head diameter, and the barred body afterbody is that screw thread combines with caput, and caput is difficult for combining with surrounding bone, if when carrying out artificial hip joint replacing, the caput taking-up is got final product; (5) elastic modelling quantity of titanium alloy is good near the elastic modelling quantity and the compatibility of human body bone, and postoperative patient does not have significant discomfort; (6) best period of using support stick placement in the treatment femur head necrosis is early stage in pathological changes, and promptly to learn structural damage be before the joint subsides to subchondral bone pressure, i.e. FicatI-III, the curative effect that the III phase is partly subsided and also can effectively be satisfied with.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of barred body.
Fig. 3 is the structural representation of caput.
Drawing explanation: 1, caput 2, barred body afterbody 3, screw 4, guide pinhole
The specific embodiment:
Describe embodiment in detail in conjunction with above accompanying drawing, support stick is by caput 1, barred body afterbody 2 is formed, barred body afterbody 2 is that hollow is cylindric, the long screw 3 of 20mm is arranged on the head outer wall of barred body afterbody 2, be used for the fixing of femoral shaft Cortex Lycii, hexagonal hole in the 7mm is arranged in it, being used for support stick inserts and takes out, a guide pinhole is arranged in the hexagonal hole, the external screw thread that has on the barred body afterbody combines with the female thread of 1 li of caput and screws, the top of caput 1 have one with barred body afterbody 2 concentric guide pinholes, the material that support stick is selected for use is a titanium alloy, squeezes into guide pin under guiding with C type arm X-ray machine during use, support stick is inserted in the femoral head, make the top of caput 1 arrive 4mm place under the costal cartilage, can select suitable support stick to insert according to the distance of subsiding if any subsiding, the front end of barred body afterbody leaks outside, and side seam road 2mm be advisable outside femoral head.
Claims (4)
1. support stick of inserting in the femoral head, it is characterized in that: barred body is that hollow is cylindric, on the afterbody outer wall of barred body screw is arranged, in interior hexagonal hole is arranged, a guide pinhole is arranged in the hexagonal hole, the barred body afterbody all is to screw with caput to combine, and one and the concentric guide pinhole of barred body afterbody are arranged at the top of caput.
2. a kind of support stick of inserting in the femoral head according to claim 1 is characterized in that: the long 7mm of screw on the barred body head outer wall.
