Description
Technical field
This utility model is used for technical field of medical instruments, particularly relates to the personalized steel plate of a kind of microwave ablation deactivation treatment osteosarcoma.
Background technology
Osteosarcoma is modal former malignant bone tumor, and disability rate is high, and before the seventies in last century, primary treatments is amputation.Along with appearance and the application of chemotherapeutics, 5 years survival rates of Patients with Osteosarcoma are by 10% ~ 20% rising to present 60% ~ 78% before.Limb-sparing surgery reaches more than 80%.Original position microwave ablation process tumor section assists Plate internal fixiation to treat the method for Primary Malignant Bone Tumor, observed good clinical therapeutic efficacy, comprising oncology's index and limb function index in medium-long term is followed up a case by regular visits to.Under the prerequisite of this Therapeutic Method main normal structure around the tumor that adequately protects, by local heat killing tumor cells, then strike off slough, not only retain the function of suffering limb to a great extent, also there is good biological effect.The deactivation of original position microwave ablation assists Plate internal fixiation technology fully remain the normal structure of self of patient and have the inactivated bone tissue of supporting role, while the guarantee survival of patients phase, retain the limb function of patient to greatest extent, avoid the complication such as the fatigue of mechanical prosthetic and the immunologic rejection in allosome joint.
But original position microwave ablation operation case also finds following problem in recent, Long-term:
1. anatomic form does not mate: at present the bone tumor internal fixation system steel plate used of performing the operation adopts unified manufacturing process, the steel plate matched with anatomic form of lacking individuality, and current bone tumor, particularly osteosarcoma is mainly in teenager, the bone docile effect that the postoperative steel plate of microwave can not reach good is found from clinical operation, cause the postoperative stress occurring internal fixtion to be concentrated, occur the complication such as broken nail, fracture.According to the literature, the fracture that microwave is postoperative incidence rate 11% again.
2. steel plate thickness is not enough, and condylus medialis femoris is fractured: bone-solveddestructed lesion appears in Patients with Bone Tumor majority, and after high-temperature heating, sclerotin occurs that mechanical property changes, and requires stronger internal fixation system.The thickness of the standard steel plate that present stage uses is 4.5cm, is difficult to the mechanical requirements meeting early loading.Finite element analysis display inner side is when cortical bone defect area reaches 85%, and stress will be concentrated in distal femur, there is risk of bone fracture.Condylus medialis femoris risk of bone fracture is larger.
3. the mid-nail of art owes desirable: tumor size, the sclerotin rejecting scope of each patient are all different, and need in art effectively to put nail according to the concrete condition of each patient, it is more that traditional internal fixation steel plate there will be tumor region nail, and cloth nail difficulty, affects bony remodeling.
4. screw is not placed by corner: screw is placed by the corner of each patient, may add postoperative steel plate corner Plate break.
Utility model content
For solving the problem, this utility model provides a kind of microwave ablation deactivation treatment osteosarcoma personalized steel plate.It carries out personalized designs according to preoperative CT and MRI image, makes it to match with the anatomic form of tumor section bone, can reach good bone docile effect, avoids the postoperative stress occurring internal fixtion to concentrate, the complication such as broken nail, fracture.
This utility model solves the technical scheme that its technical problem adopts: the personalized steel plate of a kind of microwave ablation deactivation treatment osteosarcoma, comprise steel plate body, steel plate body has and can mate the coating surface of fitting with patient's diaphysis, described steel plate body comprises the focus portion that can coordinate with patient's diaphysis end and can with the fixed part coordinated in the middle part of patient's diaphysis, form the bending with patient's diaphysis tendency between described focus portion and fixed part, steel plate body all arranges some fixing holes in focus portion and fixed part.
Be further used as the improvement of technical solutions of the utility model, described steel plate body is by passing through 3D printing shaping after the modeling of scan patients diaphysis.
Be further used as the improvement of technical solutions of the utility model, the fixing hole in described focus portion is distributed in the surrounding of patient's diaphysis focal area, the distance >=2.7cm at the fixing hole in focus portion and edge, focal area.
Be further used as the improvement of technical solutions of the utility model, described focus portion and/or fixed part are provided with some structure through holes.
Be further used as the improvement of technical solutions of the utility model, the thickness of described steel plate body is 6cm.
Be further used as the improvement of technical solutions of the utility model, described fixing hole is common through hole or screwed lock hole.
The beneficial effects of the utility model: this steel plate body has and can mate the coating surface of fitting with patient's diaphysis, this coating surface can carry out personalized designs according to preoperative CT and MRI image, make it to match with the anatomic form of tumor section bone, good bone docile effect can be reached, the postoperative stress occurring internal fixtion is avoided to concentrate, the complication such as broken nail, fracture.In addition, this utility model is all on focus portion and fixed part and arranges fixing hole, and bending place does not arrange screw, avoids postoperative steel plate at rupture.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is focal area schematic diagram on patient's diaphysis and solid;
Fig. 2 is this utility model structural representation;
Fig. 3 is this utility model using state structural representation.
