As shown in fig. 1 to 6 together, the auxiliary fixing device for positioning the magnetic resonance limb at a variable angle comprises a base 1, wherein the base 1 is conventionally arranged on an examination bed for magnetic resonance for use. The base 1 is fixedly provided with a vertically arranged mounting column 2, the upper end face of the mounting column 2 is provided with a ball socket 3, and a ball 4 is mounted in the ball socket 3. The ball 4 and the ball socket 3 form a ball joint which can realize universal adjustment and is beneficial to adjusting to a required angle. Based on the influence of metal to magnetic resonance, this embodiment base 1 the erection column 2 the spheroid 4 all prefers the plastics material, just the erection column 2 is preferred with base 1 an organic whole is moulded plastics and is formed. Based on the integral injection molding and the existence of a certain height of the base 1, the ball socket 3 can be set to be a lower height, so that the overall height of the embodiment can be reduced, and the use of legs, arms and other limbs is facilitated.

The utility model discloses a ball-and-socket joint, including mounting column 2, the up end department of mounting column 2 is equipped with clamping ring 5, an organic whole is equipped with on clamping ring 5 can press extremely pressing portion 51 on the spheroid 4, the nut 6 that pressurizes is installed to the screw thread on the outer peripheral face of mounting column 2, the upper end department an organic whole of nut 6 that pressurizes is equipped with and can press extremely the pressing portion 61 on the upper surface of clamping ring 5. The ball body 4 is provided with a connecting part 41 extending out of the ball socket 3 and the pressing ring 5, and the connecting part 41 is provided with a limb fixing component 8.

The limb fixation assembly 8 is used to immobilize a limb. In this embodiment, the limb fixing assembly 8 includes a supporting plate 81 fixedly connected to the connecting portion 41, a pressing fixing band 82 is disposed on the supporting plate 81, and after the limb is placed on the supporting plate 81, the limb is fastened on the supporting plate 81 by using the pressing fixing band 82, so as to fix the limb. The compression fixing belt 82 is usually a restraining belt cooperating with a buckle or a hook and loop fastener to fix the limb to other supporting structures, which is well known to those skilled in the art and will not be described herein. Also based on the influence of metal on magnetic resonance, the connecting portion 41 and the supporting plate 81 are preferably made of plastic, and the connecting portion 41 is preferably integrally injection-molded with the ball 4 and is fixedly connected with the supporting plate 81 by a bolt, which is also preferably a plastic bolt.

In this embodiment, after the limb to be imaged is fixed on the limb fixing assembly 8, the pressing nut 6 is loosened, that is, rotated and moved upward along the axial direction of the mounting post 2, the pressing effect of the pressing portion 61 on the pressing ring 5 gradually disappears, the pressing effect of the pressing portion 61 on the ball 4 gradually disappears, and the ball 4 can freely rotate in the ball socket 3, so that the limb fixing assembly 8 can freely adjust the angle, and the limb to be imaged can easily swing. After the positioning is finished, the pressing nut 6 is screwed, that is, the pressing nut 6 is rotated and moves downwards along the axial direction of the mounting post 2, the pressing part 61 applies pressure to the pressing ring 5, the pressing part 61 is tightly pressed on the ball 4, and the ball 4 can be tightly fixed in the ball socket 3 by means of friction force generated by the pressing acting force, so that the fixation of the positioning angle of the limbs is realized.

Preferably, an elastic cushion 7 is further arranged between the upper end face of the mounting column 2 and the compression ring 5. The deformable characteristic of the elastic pad 7 can provide a certain surplus stroke for the pressing of the compression ring 5, and the effective pressing of the pressing part 51 on the ball 4 is ensured. Meanwhile, the elastic pad 7 can generate reverse elastic acting force after being pressed and deformed by the compression ring 5, and the pressing nut 6 is not easy to loosen due to the elastic acting force, so that the fastening reliability of the ball 4 and the ball socket 3 is ensured, and the stability of the limb positioning angle is ensured.

Preferably, the pressing part 51 is provided with a pressing arc surface 52 adapted to the outer surface of the ball 4, so as to increase the contact area between the pressing part 51 and the ball 4, further increase the friction force generated after pressing, and further ensure the fastening reliability of the ball 4 and the ball socket 3 and the stability of the limb positioning angle. The outer circumferential surface of the pressure applying nut 6 is provided with anti-skid protrusions, so that manual work can effectively rotate the pressure applying nut 6; the antiskid projections can be realized in a dot shape or a stripe shape.

Preferably, a level is installed on the supporting plate 81 to visually judge that some directions need to be kept horizontal in a specific situation. Still further, the levels include a pitch level 83 and a yaw level 84. The pitch level 83 may be disposed at the proximal side and/or the distal side of the blade 81, which is illustrated as both positions in this embodiment; the side turn level 84 may be located at the left and/or right of the torso of the platform 81, both locations being illustrated in this embodiment. Therefore, when only the pitch angle of the limbs needs to be adjusted, the horizontal condition in the left and right directions can be observed through the lateral rotation horizontal ruler 84, so that the limbs are prevented from being driven to rotate laterally carelessly in the process of adjusting the pitch angle; similarly, when only the lateral rotation angle of the limb needs to be adjusted, the horizontal situation of the head and foot directions can be observed through the pitching level ruler 83, so that the situation that the limb is carelessly driven to pitch and rotate in the lateral rotation angle adjusting process is avoided.

In the embodiment, the suction cup assembly 9 is installed at the bottom of the base 1 to assist in enhancing the fixing effect of the embodiment on the examination bed. Conventionally, the suction cup assembly 9 is implemented by using at least three non-collinear suction cups, and the present embodiment is only illustrated by four rectangular suction cups. This embodiment be equipped with sucking disc groove 11 on the bottom surface of base 1, install in sucking disc groove 11 sucking disc subassembly 9, the bottom of sucking disc subassembly 9 stretches out the bottom surface setting of base 1 is in like this back on the inspection bed is leaned on to base 1 seat, the sucking disc can be out of shape to accomplish the negative pressure adsorption effect by the same trend, and because the existence of sucking disc groove 11, the sucking disc that forms the negative pressure adsorption deformation is difficult to the protrusion outside the bottom surface of base 1, therefore base 1 is firmly leaned on easily on the inspection bed, the whole use that can stabilize of this embodiment. Preferably, a base opening 12 for conveniently lifting the base 1 is formed in the side wall of the suction cup slot 11, so that the negative pressure adsorption effect of the suction cup can be conveniently relieved, the position can be freely switched, and the use flexibility is improved.

The installation of the limb fixing component 8 on the base 1 is realized in a ball joint mode, so that the angle of the limb fixing component 8 can be conveniently adjusted according to actual needs, and the adaptation to the positioning of various limbs is realized. The angle adjustment and the angle fixation can be realized only by loosening and screwing the pressure applying nut 6, and the operation is very convenient. This embodiment can assist various limbs to put the position and fix, and the limb can carry out the formation of image inspection under required angle, does benefit to smoothly and forms clear formation of image.
