Description of the invention: [Technical field to which the invention belongs] This April is a modification of the artificial femoral stem structure, especially an artificial femoral stem that is applied to the hip joint structure between the human femur and the bone. . [Prior Art] ^ Since the end of the 19th century, the quality and technology of the artificial hip have been matured since the advent of the artificial hip joint, and the artificial femur is more effective in avoiding the bone dissolution phenomenon due to the advancement of science and technology in the month-wide. The design of the handle can refer to the Republic of China Patent Announcement No. (4), 359159, 5758551, 532153. From the front file, the duck can be seen, and the artificial stem and the femoral stem tend to be single-bend angle-bodyized. For the surgeon, because each patient's human body has a different angle from the femur, if the patient uses a different angle of the femoral stem, it may cause postoperative complications and lead to replacement. To this end, please refer to US Patent Publication No. 6464728, which discloses an artificial femoral stem with a stepless adjustable angle of attachment, which forms a toothed surface or a perforation through the joint surface of the femoral neck and the femoral stem. The arrangement of the surface allows the surgeon to analyze the femoral anteversion angle of the human body. During the operation, the femoral neck of different forward angles is replaced according to the patient's condition. However, this practice still causes trouble. The main reason is that Although the design can effectively solve the disadvantages of traditional artificial anterior tilt angle design of artificial femoral stem, the surgeon must use the tight fitting method to combine the femoral neck components during the operation. In the minimally invasive surgery of small wounds, the narrow operation space will be The difficulty in combining the femoral neck elements. SUMMARY OF THE INVENTION The main object of the present invention is to solve the above-mentioned shortcomings and avoid the existence of a defect. The present invention provides a separate type of a limiting mechanism having an auxiliary alignment and a biasing portion capable of conveniently controlling the limiting mechanism from the outside. In the design of the artificial femoral stem, the present invention utilizes a joint end of the femoral neck member to correspond to the femoral stem member, and a restriction mechanism for satisfying the engagement position of the femoral neck member with respect to the femoral stem member, and through the assembly end of the femoral neck member. A urging portion for the operator to obtain a simple manipulation of the limiting mechanism to achieve a relative engagement position between the femoral neck member and the femoral stem member, so that the surgeon can easily replace the femoral neck member with different forward tilt angles depending on the patient's condition, and The invention can be positioned by the femoral neck component to control the limiting mechanism, so that the wound can be effectively reduced, and the surgeon can be more suitable for surgery and patient recovery. [Embodiment] 1247601 & A detailed description of the gamma and technical lying, the thief is illustrated as follows: "The second, sixth _ shows" is the structural decomposition of the present invention, the appearance of the stereo and the embodiment: As shown in the present invention, the present invention includes a femoral stem that connects the human femur 4Q and a femoral neck member that is located at the femoral neck. The femoral neck member 2G is used to connect the femoral ball disposed in the human body A 2 / shown. The head element 30, wherein the femoral neck element 20 and the femoral stem element are widely used by the user: 21 and the limiting mechanism must satisfy the engagement position of the femoral neck element 2 〇 variable 21 m to 1 G. The concave portion 111 corresponding to the end portion of the strand 2G and the joint surface of the retaining hole 111 and the joint end 21 are provided with the spacing row 212 and the convex portion 112, 211 ' and the concave portion 113 in the positioning hole 111 has an extension. For example, the lower limit groove 114' of the lower edge of the iliac crest 12 is formed by the joint end 22 of the femoral neck member 20, the outer convex portion 211 is connected by the femur%, and the end portion of the femoral neck member 11 is gradually widened. The femoral component 30 of the lateral section is a urgency mode, and the group of 侏tr22 is provided with an operation. The operator facilitates the manipulation of the limiting mechanism to achieve the femoral neck element 20 盥 femoral stem element: the urging portion 221 of the ox 11 butterfly engagement position, and the binding end 21 and the assembly end 22 have a closed section 23, the closure The segment 23 has a corresponding convex portion u in the corresponding positioning hole (1) and a closed surface 232 for closing the positioning hole. The door is again _ 231 帛 帛 3, 5 - 卜 5 - 2, 6 picture 』 ' County invention combination profile, section actuation and = exemplification as _ shows: when the doctor manually cut the hand (four), the first share The material of the handle 1 is implanted into the femur of the human body, and then the angle of the femur of the patient is tilted forward. For example, the surgeon should perform the bending (four) degree R of the facial component 2G, where the _ ^ junction 22 has a relative joint end 21 - f curvature R, and the f-curve angle r-mediated Lin Ming design can be forwarded 2Q ^ ^ = according to the positive body of the human body, the 113 of the lower end 21 of the Lixia bone private member 20, and the outer peripheral recess 212 of the opposite joint end 21 Then, the convex portion 112 in the positive positioning hole ιη can smoothly enter the positioning hole m, and when the convex portion 211 of the joint end 21 exceeds the positioning hole: and the m depth, that is, the extension 231 of the femoral neck element (10) When the depth is slightly equal to the position of the fixed portion = ^ portion 112, the surgeon can directly apply force to the set end 22 of the femoral component 2Q to rotate the convex portion 211 of the sister assembly 21 into the limiting slot 114, so that the binding end 21 The convex portion 211 is not detached by the positioning hole ΐιϋ 1247601 convex portion 112, and if it is a small injury, the Q-seen-known femoral neck member 20 enters an angle, and is applied at a force ^ Move the tree, the surgeon can also use the visual arranging side, her force 221 'can be simply applied to control the bone neck °' with the tool 50 (such as hex wrench), if the installation is found to be wrong, then reverse Operation is light: 2Q positioning or lifting the card "system; femoral neck tree 2G and the handle element n of the fixed money can be _« positioning; in the completion of the positioning hole 111 without causing a gap, at this time, and then the components The sealing surface 20 of the sealing surface 20 of the pressing member 20 is provided with an engaging hole & = the corresponding femoral neck element and the femoral neck element 20 in the bone ball head element 30 are conveniently arranged. With the help of the home, the femoral ball head element 30 can be placed on the right side of the femur for the patient to complete the installation of the above-mentioned femoral stem 3〇. When the installation angle is found to be incorrect, it must be adjusted: component two, month, =头元科^ 22 , Γτ^ 'When it is convenient to reduce the risk of surgery and increase its treatment: ', ', the preferred embodiment of the present invention is not intended to limit the implementation of the invention. The equivalent changes and modifications of the content should be the 1274061 of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic exploded view of the present invention.
