Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to an acetabular tool, an acetabular file system and an acetabular trial model system.
Background
The population of China tends to be old, more and more middle-aged and elderly people wear hip joints due to the increase of age, and the probability of hip joint lesions is increased year by year along with the change of life style of people. Total hip replacement is an effective approach to treat hip joint deformity, lesions, wear, and even hip fractures. The hip joint replacement requires the original bone excision of the acetabular side and the femoral side, and then the existing artificial prosthesis is implanted therein to achieve the purpose of simulating the movement function of the original hip joint.
The prior acetabular side surgery mainly uses an acetabular file to file an acetabular fossa of a patient, and the acetabular file needs an acetabular file connecting rod to be connected and driven, so that the file function is achieved through high-speed rotation. Because the size of the acetabular fossa of each person is different, the acetabular rasp needs to be provided with specifications with diameters from phi 38 to phi 71 according to the size of the acetabular fossa, and the different specifications are different by a gradient of one millimeter, so that 34 specifications are needed; after the acetabular fossa is filed, an artificial acetabular cup can be implanted theoretically, but in order to ensure one success, an acetabular test mold is used for simulating the implantation condition of the acetabular cup, and the conventional acetabular test mold comprises specifications with diameters from phi 42 to phi 64, wherein the gradient of two millimeters is different between each specification, and the total of 12 specifications; besides the difference of acetabular fossa, the femoral heads of the human bodies are also greatly different, and the diameters of the femoral heads under the acetabular fossa with the same size are possibly different, so that when the implantation situation of the acetabular cup is simulated in operation, an adapter tool, namely an inner lining test die, is also needed between the outer cup test die and the ball head test die, and the number of common specifications of the inner lining test dies is 17; in summary, to complete the basic acetabular surgery, 64 tools are required to be configured, so that the number of the surgical tools makes the acetabular surgery very complicated, and has very high requirements on the high concentration of the spirit of doctors, so that the reduction of the number of the surgical tools is one of the problems to be solved in hip joint replacement surgery;
in addition, in the acetabular side operation, the commonly used acetabular file connecting rod is combined with a cross fixing frame on the acetabular file, so that the connection effect is achieved, because the file with a relatively smaller specification cannot be selected directly for filing each time, the file with a relatively smaller specification is selected for filing, then repeated filing is replaced by each specification until the file is found to be suitable, and meanwhile, the angle of the file is required to be adjusted in the filing process, so that the acetabular file connecting rod and the acetabular file are not only in driving connection but also in need of being fixed and inseparable in torsion and push-pull, the structure of the acetabular file connecting rod is relatively complex, and the subsequent cleaning and recycling and the adverse effects are caused;
furthermore, conventional acetabular files are easy to wear due to the design defect of the filing edge, so that the conventional acetabular files are removed as wearing parts, which causes great waste of tool quantity and cost.
Based on the defects, the invention discloses an acetabular tool, an acetabular file system and an acetabular trial system, which are used for solving the problems in the prior art.
