Description of the invention: • Technical field to which the invention pertains The present invention provides a technical field of an accessory for hip joint replacement surgery, and more particularly to an assistive device for hip surface replacement surgery. Copy the artificial femur completely identical to the human bone, and judge the position of the central hole, and use the reverse push data to make the positioning device accessory. The positioning device is used for the human bone, and the artificial femur element can be accurately drilled and ground. Piece 'up to success rate. [Previous technique] According to the hip surface replacement surgery, the target of the surgery is for the younger group and the bone is a good person, but the cartilage of the hip surface of the person is broken and cannot be repaired. Therefore, it is necessary to have an I. The femoral component, for young and highly active patients, the body Guanming bottle closure is the surface replacement surgery because it retains more bone characteristics and artificial joint contact surface, where Qianmu has caused interest in the orthopedic community. And re-taken to treat osteoarthritis. ... Although there are short-term clinical follow-up reports at this stage, (4) the effect of joint surface replacement is good, but because of the difficulty of this operation, there are still cases of artificial joints and femoral components placed improperly in the operation. Postoperative component k early damage failure doubts. Therefore, ... the accuracy of the artificial closure of the femoral component implantation position f is an important key to the success of the hip replacement. Therefore, in view of the above-mentioned sequel to the traditional structure, how to create an innovation that is more ideal and practical - like new ', ·. Structure, the real consumer is eagerly awaiting, 201204310 is also the relevant industry to work hard to develop breakthrough goals and directions. In view of this, the inventors have been engaged in the manufacturing development and design experience of related products for many years, and have applied the design and prudent evaluation to the above objectives, and have finally obtained the practical invention. SUMMARY OF THE INVENTION Technical problem to be solved: At present, although there is a short-term clinical follow-up report indicating that the effect of body and body surface replacement is good, but because of the difficulty of this operation, there are still artificial joint femurs during the operation. Improper placement of components causes premature failure of post-operative components. Therefore, the accuracy of the implantation position of the artificial joint femoral component is an important key to the success of the hip joint replacement surgery. Technical Features of the Problem: Provide an assistive device for hip surface replacement surgery, which is performed by computed tomography ( CT) Obtained the image and data (RP) of the proximal femoral tomography of the artificial femur. This data was used to create the artificial femur of the same human bone. The physician judged the position of the central hole with the artificial femur, and the computer used the reverse data to create the positioning device. Then, the positioning device is placed on the human bone to perform surface replacement, and the hole is directly drilled according to the position of the center hole of the positioning device. Then, using the special tool of the prior art, the mandrel directly penetrates into the drilled hole and grinds the cylindrical surface of the femur with a special tool, and then installs the artificial femoral component to complete the precise application. Compared with the efficacy of the prior art: the assisting device for the hip surface replacement surgery of the present invention is completely suitable for the patient because it is based on the true 3D stereoscopic copy of the human bone and reverses the assist device of the 201204310 data. And it is in the artificial month of the bones; 隹~ 仃 仃 judging the center hole position, and the reverse data to make the positioning device aids' therefore does not cause inconvenience or pain to the patient, and the physician has a positioning device The help of Auntie Auxiliary Tools can be used to implant the femoral component of the artificial joint with the equivalent position of Bi Hui, 4- ^ to improve the success rate of hip surface replacement surgery to the best. With regard to the technology, the means and the functions of the present invention, it is to be understood that the above-mentioned objects, structures and features of the present invention will be described in detail with reference to the drawings. . [Embodiment] Referring to the first to the first "quote", "Γ" ^ '不' the present invention provides a kind of auxiliary tool for the hip replacement surgery, including: computed tomography (CT) human bone femur (1〇) Obtaining femur data (Rp)' with this data to make an artificial femur (2Q) of the same shape as the human bone femur (10). The artificial femur (2〇) defines its central hole (21) position 'Computer Calculate the positioning device (4) with the inverse data (3). According to the data, a humanized positioning device accessory (3〇), artificial femur (20)#, and a feature area of the positioning device accessory (3〇) are created (2 2 ) and the positioning device 罝 (3 1 ) must be able to be closely positioned, and the upper edge region must be reserved between the articular cartilage (40), the personalized positioning device accessory (30) has the corresponding artificial femur 201204310 The situation can be a problem with the bones. The cartilage is broken to replace the original human bones (l 〇). It is not serious enough to cut off the hip surface replacement surgery. If the joint surface of the femur is soft and cannot be repaired, the bones are good. , but the surface is off, there is no need to remove it at this time. It is necessary to change the cartilage of an artificial femoral component to obtain the data (RP) of the human femur (1 using computerized tomography scan (CT) 。). After obtaining this data, it can be made with human bones. 0) Prototype. The physician then judges the central hole (2丄) position with the artificial femur (20). Then use the reverse data to make the positioning device aid (3 〇). The positioning device accessory (30) is then placed on the human femur (1〇) for surface replacement, which includes direct drilling into the human femur according to the central hole (3 2 ) position of the positioning device accessory (3 〇).丄〇) ^ Re-use the special tool of the pen to penetrate into the drilled hole and use this special tool to grind the cylindrical surface of the moon and bone (5 〇). Refilling the artificial femoral component (5 1 ) is complete. A possible embodiment is to obtain the proximal femoral image and data of the artificial femur (2 ο ) by CT tomography (General EIectric, Milwaukee, WI, USA) for the narrative (Amira, Konrad-Zuse-Zentrum fur informationstechnik
