[ detailed description ] embodiments
A neuro-anatomical device capable of universal rotational fixation according to the present invention is described in further detail below with reference to specific embodiments.
As shown in fig. 1 and 2, the nerve dissecting device capable of being universally rotated and fixed comprises a base 1 located at the bottom, wherein a dissecting plate 2 is arranged above the base 1, and a plurality of groups of retractable thimble mechanisms are arranged on the dissecting plate 2. The thimble mechanism comprises a vertical column 3 arranged on the dissecting plate 2, a thimble 4 arranged in the horizontal direction is connected in the vertical column 3 in a threaded manner, and a knob 5 is arranged at the tail part of the thimble 4. Be provided with universal rotary mechanism between base 1 and anatomical disk 2, as shown in fig. 3, universal rotary mechanism is including setting up fixed column 6 on base 1, setting up in the dwang 7 of anatomical disk 2 bottom and overlapping the lock sleeve 8 of locating fixed column 6 outside, the bottom of dwang 7 is provided with spherical commentaries on classics ball 9, the top surface of fixed column 6 is the concave cambered surface 10 corresponding with the lower part sphere of commentaries on classics ball 9, and the lower part of commentaries on classics ball 9 sets up in this concave cambered surface 10, the outside of commentaries on classics ball 9 is located to the upper portion cover of lock sleeve 8 to the upper portion inner wall of lock sleeve 8 is the concave cambered surface 11 corresponding with the upper portion sphere of commentaries on classics ball 9, is provided with the locking mechanical system that is used for driving lock sleeve 8. The locking mechanism comprises a hollow adjusting box 12 provided with a side part of a locking sleeve 8, a side plate 13 is arranged on the side part of the fixing column 6, the side plate 13 is arranged inside the adjusting box 12, a vertical threaded hole 14 is formed in the side plate 13, through holes 15 are formed in the top wall and the bottom wall of the adjusting box 12, which are vertically opposite to the threaded hole 14, adjusting screw rods 16 penetrate through the threaded holes 14, the upper ends and the lower ends of the adjusting screw rods 16 penetrate through the adjusting box 12 after passing through the through holes 15 respectively, nuts 17 are arranged on the upper ends of the adjusting screw rods 16, and rotary rods 18 used for rotating the adjusting screw rods 16 are arranged in the lower ends of the adjusting screw rods.
Preferably, a limiting hole 19 is formed in the opposite side of the locking sleeve 8 on the adjusting box 12, a limiting screw 20 is arranged in the limiting hole 19, the diameter of the limiting hole 19 is larger than that of the limiting screw 20, and the front end of the limiting screw 20 is connected with the fixing column 6.
