[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0020] Please refer toFigures 1-4 A Kirschner wire tension adjustment device comprises an outer shell 1, an inner cavity of the outer shell 1 is provided with a long tube 2, an inner wall of the top of the long tube 2 is fixedly equipped with an internal threaded tube 3, the inner wall of the internal threaded tube 3 is threadedly connected with a screw rod 4, a connecting rod 9 is fixedly equipped at the bottom of the screw rod 4, a round block 10 is fixedly equipped at the bottom of the connecting rod 9, and a left through hole 11 and a right through hole 12 are opened at the bottom of the round block 10. When the tension band is wrapped around the Kirschner wire, the head end and the tail end of the tension band are respectively passed through the left through hole 11 and the right through hole 12, and the connecting rod 9 and the round block 10 are driven to rotate by the rotation of the screw rod 4, and the tension bands located in the left through hole 11 and the right through hole 12 are twisted together. When the screw rod 4 rotates, the round block 10 is displaced upward in the long tube 2. At this time, the long tube 2 is still in contact with the patient's bone. The long tube 2 can twist the tension band while contacting the patient's bone, thereby improving the stability of the device.
[0021] In a preferred embodiment, the left perforation 11 and the right perforation 12 are both connected to the long tube 2, and the inner edges of the left perforation 11 and the right perforation 12 are both rounded, so that the head end and the tail end of the tension band pass through the left perforation 11 and the right perforation 12 and enter the long tube 2, so that the tension band can completely contact the inner walls of the left perforation 11 and the right perforation 12, so that the tension band is twisted more firmly, and the inner edges of the left perforation 11 and the right perforation 12 are rounded, so that the head end and the tail end of the tension band are in contact with the rounded corners of the left perforation 11 and the right perforation 12 respectively, so that the head end and the tail end of the tension band can slide into the left perforation 11 and the right perforation 12 through the rounded corners, which facilitates the head end and the tail end of the tension band to enter the left perforation 11 and the right perforation 12.
[0022] In a preferred embodiment, a hexagonal column 5 is fixedly installed on the top of the screw rod 4, a rotating plate 6 is fixedly installed on the outer edge of the hexagonal column 5, a vertical rod 7 is fixedly installed on the end of the rotating plate 6 away from the hexagonal column 5, and a sleeve 8 is movably sleeved on the outer edge of the vertical rod 7. By holding the sleeve 8 by hand and then rotating the sleeve 8 around the hexagonal column 5, the rotating plate 6 can rotate and drive the hexagonal column 5, the screw rod 4, the connecting rod 9 and the round block 10 to rotate, thereby improving the rationality of the device.
[0023] In a preferred embodiment, a mounting hole 13 is formed on the outer wall of the outer shell 1, and a transverse threaded tube 14 is fixedly mounted on the inner wall of the mounting hole 13. A handle 15 is threadedly connected to the inner wall of the transverse threaded tube 14. By using the setting of the handle 15, the left hand can hold the handle 15 and the right hand can hold the sleeve 8 for rotation during use, which is convenient for the user to operate.
[0024] In a preferred embodiment, an anti-slip groove 16 is provided on the outer edge of the grip 15, and a clamp 17 is fixedly assembled on the top of the outer housing 1. The height of the clamp 17 is lower than the height between the rotating piece 6 and the outer housing 1. By screwing the grip 15 onto the transverse threaded tube 14, the grip 15 can be detached from the transverse threaded tube 14. The detached grip 15 can be clamped on the clamp 17, and the clamp 17 can fix the grip 15, making it not easy to lose. At the same time, the width of the whole device becomes narrower, making the device convenient for storage.
[0025] In a preferred embodiment, the outer housing 1, the long tube 2, the round block 10 and the grip 15 are all made of stainless steel. Utilizing the property that stainless steel is not easily corroded, the device will not be corroded after long-term use, and no rust will appear on the surface, improving the safety and service life of the device.
[0026] Working principle: When in use, the Kirschner wire is installed on the patient's bone, and then the tension band is wound around the Kirschner wire. Then, the head end and the tail end of the tension band are respectively passed through the left perforation 11 and the right perforation 12. Then, hold the grip 15 with the left hand and hold the sleeve 8 with the right hand. Then, rotate the sleeve 8 around the hexagonal column 5. At this time, the rotating piece 6 rotates to drive the hexagonal column 5, the lead screw 4, the connecting rod 9 and the round block 10 to rotate. The round block 10 rotates to twist the tension band together. At this time, the long tube 2 contacts the patient's bone, and the round block 10 moves upward on the long tube 2. After the tension band is twisted, separate the long tube 2 from the patient's bone. Then, disinfect the whole device. Then, unscrew the grip 15 from the transverse threaded tube 14, and then the detached grip 15 can be clamped on the clamp 17 for convenient storage.
