The end parts of the forceps mouths 11 of the two forceps bodies 1 are embedded with a rotatable rotating shaft 2, the side walls of the two rotating shafts 2 are respectively fixed with a hollow conduit 3 used for penetrating a medical steel wire 5, the front end of the hollow conduit 3 is arc-shaped, when the two forceps mouths 11 are clamped, the front ends of the two hollow conduits 3 are mutually butted to form a wire passing channel used for encircling the tubular bone 6.

More specifically, referring to fig. 1, 2 and 4, the hollow conduit 3, the forceps body 1 and the shaft 2 are made of metal, the end of the hollow conduit 3 is welded to the front end sidewall of the shaft 2, a through hole 15 is opened at the end of the forceps mouth 11, the through hole 15 extends from the forceps mouth 11 to the outside of the forceps body 1 in the direction of the forceps handle 12, the shaft 2 is inserted into the through hole 15, and the end of the shaft 2 extends through the through hole 15 and extends to the outside of the through hole 15. A plurality of limit concave strips 151 are arranged on the inner side wall of the through hole 15 at equal intervals in a surrounding mode, and limit convex strips 21 matched with the limit concave strips 151 are arranged on the outer side wall of the rotating shaft 2. In this embodiment, the limiting protruding strip 21 may be directly carved on the outer sidewall of the rotating shaft 2, or a plastic sleeve (not shown) may be fixedly sleeved on the outer sidewall of the rotating shaft 2, the plastic sleeve is fixed on the outer sidewall of the rotating shaft 2 in a manner of fastening or gluing, and the limiting protruding strip 21 is disposed on the plastic sleeve. The outer side wall of the tail end of the rotating shaft 2 is provided with a plurality of degree marks 22 for marking the rotating angle of 360 degrees in a surrounding mode, and the clamp body 1 is provided with a pointing arrow 14 for pointing the degree marks 22. The end part of the tail end of the rotating shaft 2 is fixedly provided with a knob 23 which is convenient for medical staff to rotate the rotating shaft 2. The limiting concave strips 151 and the limiting convex strips 21 can be matched with the degree marks 22 on the rotating shaft 2 except for the functions of skid resistance and limiting, so that the medical staff can accurately control the rotating angle of the rotating shaft 2. In addition, when the directional arrows 14 of the two forceps bodies 1 respectively point to the degree mark 22 marked as 0 degree on the respective rotating shafts 2, the two hollow guide pipes 3 and the two forceps bodies 1 are positioned on the same horizontal plane; when the pointing arrow 14 of the caliper body 1 points to the degree index 22, which is marked 90 ° or 270 °, the hollow conduit 3 is perpendicular to the caliper body 1.

Referring to fig. 1 and 2, a fastener 4 is further arranged between the two forceps handles 12, the fastener 4 comprises an arc-shaped rack fixedly arranged on one forceps handle 12 and a tooth groove (shown in the figure) arranged on the other forceps handle 12, and the arc-shaped rack and the tooth groove are matched to prevent the two forceps handles 12 from moving relative to each other, so that medical personnel can not need to tightly hold the handles for a long time, and the front ends of the two hollow catheters 3 can be tightly butted when clamping.

When the invention is used, after a cut wound is cut to fix a long tubular bone 6 fracture main body, as shown in fig. 3, the rotating shaft 2 of one forceps body 1 is rotated clockwise by 90 degrees, and the rotating shaft 2 of the other forceps body 1 is rotated counterclockwise by 90 degrees, so that the two hollow conduits 3 are positioned at the same side and are respectively perpendicular to the respective forceps bodies 1, the two forceps mouths 11 are opened, and the two hollow conduits 3 are respectively extended into the upper side and the lower side of the tubular bone 6. As shown in fig. 4 and 5, when the tubular bone 6 is located in the arc-shaped middle of the hollow conduit 3, the rotating shaft 2 of one forceps body 1 is rotated 90 ° counterclockwise, the rotating shaft 2 of the other forceps body 1 is rotated 90 ° clockwise, and the forceps mouth 11 is clamped synchronously while the rotating shaft 2 is rotated, so that the hollow conduit 3 is attached to the tubular bone 6 as much as possible to move, and finally the two hollow conduits 3 are located on the same plane, and the front ends of the two hollow conduits 3 are butted with each other, so that the tubular bone 6 is encircled to form a wire passing channel for the medical steel wire 5 to pass through. As shown in fig. 5 and 6, the medical steel wire 5 is taken out, the medical steel wire 5 passes through the wire passage formed by the two hollow catheters 3, then the rotating shaft 2 of one forceps body 1 is rotated clockwise by 90 degrees, the rotating shaft 2 of the other forceps body 1 is rotated counterclockwise by 90 degrees, the two hollow catheters 3 are still positioned at the same side and are respectively perpendicular to the respective forceps bodies 1, the two forceps mouths 11 are opened, the steel wire guider is taken out, and the medical steel wire 5 is left at the same time, thereby completing the surrounding operation of the medical steel wire 5. In summary, when the two hollow catheters 3 encircle the tubular bone 6, the two hollow catheters 3 are controlled to move along the upper side and the lower side of the tubular bone 6 by rotating the rotating shaft 2, so that the tubular bone 6 is encircled and encircled in the minimum moving space, the encircling operation of the medical steel wire 5 is completed, the operation space and the operation wound needed by the longitudinal direction and the transverse direction of the upper side and the lower side of the tubular bone 6 are greatly reduced, and the postoperative recovery of a human body is accelerated.
