As shown in Figure 5, the supersonic motor of five nuclear-magnetism compatibilities among the present invention, wherein three, comprise that described supersonic motor B2, supersonic motor C3 and supersonic motor D4 all are located on the described external motor seat B, these three supersonic motors provide power by the silk transmission for laterally rotating shaft, vertical rotating shaft and acupuncture layer respectively, two other, comprise that the supersonic motor A1 in the two-degree-of-freedom parallel mechanism the mode that does not adopt the silk transmission, but directly and the leading screw 9 in the two-degree-of-freedom parallel mechanism link to each other, as shown in Figure 1.
In a word, the described two-degree-of-freedom parallel mechanism among the present invention is realized the translation of described U-shaped moving platform C in horizontal plane, and described hoistable platform is realized moving up and down of described U-shaped moving platform C; Described two-freedom rotary head D realizes the attitude regulation of needling structure central shaft, and described needling structure is realized the acupuncture action.
The working method of a kind of Minimally Invasive Surgery acupuncture mechanism based on the silk transmission of the present invention is as follows:
1. the two-freedom translation in the horizontal plane:
Two supersonic motor A rotations, drive respectively two leading screw 9 rotations among the lead screw transmission structure A1, two nuts 8 that leading screw 9 promotes respectively to go up separately independent of each otherly advance or retreat, and U-shaped moving platform C connects with parallelogram linkage with the nut 8 of being connected among the lead screw transmission structure A.When two each and every one supersonic motor A1 rotated synchronously, it is constant that parallelogram linkage is kept angle, seesaws in horizontal plane thereby promote U-shaped moving platform C; When two supersonic motor A1 asynchronous rotaries, the parallelogram linkage angle changes, thereby promotes U-shaped moving platform C side-to-side movement in horizontal plane, and the so far two-freedom translation in the horizontal plane realizes smoothly.
2. elevating movement:
Form the lead screw transmission structure between hoistable platform 5 and the U-shaped moving platform C, the axle head 12 by handmade rotary leading screw bottom can make hoistable platform 5 move up and down.
3. the rotation of two-freedom:
X-direction is rotated: supersonic motor B2 rotation drives initiatively by shaft coupling 17 that silk wheel 20 rotates, initiatively silk wheel 20 and by between the movable wire wheel 23 by a silk transmission, fixed by movable wire wheel and horizontal rotating shaft, thereby the X-direction that realizes two-freedom rotary head D rotatablely moves.In like manner, the Y-direction of realization two-freedom rotary head D rotatablely moves
4. acupuncture campaign:
The acupuncture campaign is to finish by the needling structure that is fixed on two-freedom rotary head D center.As shown in Figure 6, female thread leading screw 29 is installed in by plastic bearing 31 on the barrel susceptor 33 of needling structure, and the spiral type wire casing 34 that arranges on the female thread leading screw 29 outer surfaces of revolution is used for wrapping wire, drives 29 rotations of female thread leading screw by the silk transmission.The screw thread of female thread leading screw 29 cooperates with external screw thread on one of them external screw thread nut 28, external screw thread nut 28 left ends and needle body 27 chuckings, the right-hand member of external screw thread nut 28 is connected by the sliding sleeve 32 of needle body connecting rod 35 with the rear portion, key on the sliding sleeve 32 cooperates with axially directed groove on barrel susceptor 33 inner surfacies, in order to have prevented 28 rotations of external screw thread nut.When rotating under the drive of female thread leading screw 29 at driving wire, female thread leading screw 29 cooperates with the external screw thread nut, thus with the rotational transform of female thread leading screw 29 for the moving axially of the fixing needle body 27 of internal threaded nut 28, thereby realized the acupuncture campaign.
To sum up, by the rotatory acupuncture motion of the U-shaped moving platform two-freedom of the elevating movement of the translation of direction, vertical direction, rotary head rotation all around, needle body in horizontal plane, finally finish the acupuncture operation process.
Although top invention has been described in conjunction with figure; but the present invention is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic; rather than restrictive; those of ordinary skill in the art is under enlightenment of the present invention; in the situation that does not break away from aim of the present invention, can also make a lot of distortion, these all belong within the protection of the present invention.
