[0003] Although the filling blocks for bone defects currently on the market have different specifications, the basic structure and shape of the filling blocks of different specifications are the same. It is suitable for patients with different bone defects, especially for patients with severe bone defects. In other words, even if a filling block with a suitable specification can be applied, the filling block cannot be stably filled and fixed in the patient's bone defect, so as to fully fit the patient's bone defect; in addition, the structural strength of the existing filling block is not high , there may be safety hazards after long-term force or impact

Embodiment Construction
[0026] In order to better understand the purpose, structure and function of the present invention, the filler block for bone defect and its manufacturing method of the present invention will be further described in detail in conjunction with the accompanying drawings.
[0027] figure 1 with figure 2 The structure of the filling block 100 for bone defect according to the present invention is shown, and the filling block 100 is used with such as image 3 The acetabular outer cup 7 shown is fit and fixed, and the filler block 100 includes a filler body 1 for filling bone defects in the human body. The filler body 1 includes a top side beam 11, a bottom fixed side beam 12, and a joint between the top side beam 11 and the bottom side beam. The supporting fixed beams 13 between the fixed side beams 12, the two ends of the top side beams 11 are respectively connected with the two ends of the bottom fixed side beams 12, the top side beams 11, the bottom fixed side beams 12 and the s...

Abstract
The invention belongs to the field of medical apparatus, and particularly relates to a filling block for bone defects and a method for manufacturing the filling block. The filling block for bone defects is used for cooperation and fixation with an acetabular system, the filling block comprises a filling body for filling bone defect parts of a human body, and comprises a top edge beam, a bottom fixed edge beam and a support fixed edge beam connected between the top edge beam and the bottom fixed edge beam; two ends of the top edge beam are respectively connected with two ends of the bottom fixed edge beam; the top edge beam, the bottom fixed edge beam and the support fixed beam jointly form a curved inner surface being jointed with at least part of outer surfaces of the acetabular system, and an outer surface which is jointed to the inner surfaces of the bone defect parts of the human body, and the support fixed beam comprises at least two sub support fixed beams connected between the top edge beam and the bottom fixed edge beam. The filling block for bone defects has high structural strength, and can be stably filled and fixed to the bone defect parts of a patient.
Description
technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a filling block for bone defect and a method for manufacturing it. Background technique [0002] A filler block is an implantable prosthesis used in arthroplasty to provide surgeons with an alternative structural graft suitable for reconstructions caused by severe degeneration, trauma, or other pathological changes. It is mainly used for segmental acetabular defects or for the treatment of patients with femoral head necrosis without femoral head collapse. [0003] Although the filling blocks for bone defects currently on the market have different specifications, the basic structure and shape of the filling blocks of different specifications are the same. It is suitable for patients with different bone defects, especially for patients with severe bone defects. In other words, even if a filling block with a suitable specification can be applied, the filling block cannot ...
