The sheath 1 is fixed by rotating the fixing bolt 3 to ensure that when the sheath 1 slides to a predetermined position, the fixing bolt 3 can fix the position of the sheath 1 to prevent the sheath 1 from sliding and affecting the positioning effect of the bone needle. A handle 6 is provided on one side of the positioning body 4. When in use, a person holds the handle 6 and buckles the groove 5 on the fixing rod on the bracket, and then positions the bone needle through the inner sleeve 2 and the sheath 1. The inner sleeve 2 is screwed to the inside of the sheath 1 to protect the inner wall of the sheath 1 and the inner sleeve 2 can be disassembled at the same time.

[0021] In this embodiment, when in use, first a bone needle is fixed at a predetermined position of the bone, and then the fixing rod is fixed to the bone needle through the fixing block. At this time, the position of the fixing rod has been fixed. Then, when other bone needles need to be fixed, the handle 6 is manually held and the groove 5 is buckled on the fixing rod. At this time, the position of the sheath 1 is the position where the bone needle should be installed. At the same time, a hole is drilled through the inner sleeve 2 inside the sheath 1 to punch a hole at a predetermined position. After the hole is punched, the inner sleeve 2 is removed and the bone needle is passed through the sheath 1 and fixed at the punched position. After the bone needle is fixed, the positioning body 4 is removed, and the bone needle and the fixing rod are fixed by the fixing block to complete the positioning and fixation of the bone needle.

[0022] See also Figure 3 and Figure 4 In addition, in another embodiment of the utility model, the sheath 1 is provided with two, and the positions of the two sheaths 1 are fixed, so that one positioning body 4 can simultaneously position and fix two bone needles. The two sheaths 1 are both screwed on the positioning body 4, so as to adjust the protruding length of the sheath 1 on the positioning body 4, so as to ensure that the positioning and fixation of bone needles of different lengths can be adapted. The inner sleeve 2 is screwed on the inside of the sheath 1, and the position of the sheath 1 on the positioning body 4 is adjusted by rotating the sheath 1, and the position of the inner sleeve 2 inside the sheath 1 is adjusted by rotating the inner sleeve 2. The bottom of the positioning body 4 is provided with a base 9 and a fixing seat 7 slidably connected to the base 9, and the fixing seat 7 and the base 9 are buckled to form the groove 5 matched with the bracket, and the top of the positioning body 4 is rotatably connected with an adjusting bolt 8, and the bottom of the adjusting bolt 8 is screwed on the fixing seat 7, and the adjusting bolt 8 is rotatably adjusted to adjust the position of the fixing seat 7 on the base 9, so as to ensure that the positioning body 4 can be fixed to the fixing rod of the bracket through the fixing seat 7 when in use, so as to ensure the position of the positioning body 4 on the fixing rod.

[0023] In this embodiment, when in use, as in the previous embodiment, first a bone needle is fixed, and then the fixing rod is fixed to the bone needle through the fixing block. At this time, the position of the fixing rod is determined, and then the corresponding groove 5 is buckled on the fixing rod, and then the positioning body 4 is fixed to the fixing rod by rotating the adjusting bolt 8. Then, the positions of the two bone needles are determined, and the bone needle fixing process in the above embodiment is performed again to complete the fixation of the bone needle.

[0024] In summary, the utility model provides an auxiliary positioning module for a bracket, including: a positioning body, which is provided with a groove that is arranged in cooperation with the bracket, and is buckled on the bracket through the groove to ensure that the position between the bone needle and the bracket is fixed, and that after the bone needle is installed, the bone needle can be fixed to the bone needle by a combined external fixing bracket, and the bone needle and the fixing rod on the bracket are fixed by a fixing block to prevent the position between the bone needle and the fixing rod from shifting, which affects the fixing effect of the bracket on the bone needle. The positioning body is detachably connected with a sheath, and the interior of the sheath is detachably connected with an inner sleeve, and the interior of the sheath is protected by the inner sleeve, so that when drilling a hole in the bone, the inner sleeve is inserted into the interior of the sheath, thereby protecting the interior of the sheath, and ensuring that after the drilling is completed, The bone needle is positioned by the sheath and fixed at the corresponding position. The position between the sheath and the positioning body is set corresponding to the length of the bone needle.
