[0002] The wire guide for orthopedic surgery is a medical device specially used in orthopedic surgery. It is mainly used to accurately guide the wire to the predetermined anatomical position in the complex bone structure environment. Through its special design structure, such as a slender rod-shaped main part, one or both ends with a specific bend, hook or guide groove structure, during the operation, the doctor can place the wire along the channel of the guide or against the shape of the guide, so as to avoid damaging the surrounding important tissues, such as blood vessels, nerves, etc., and ensure that the wire accurately passes through the specific part of the bone, such as the drill hole near the fracture end.

[0004] In the above patent, the steel wire is guided by an arc tube, but when the steel wire is placed into the arc tube, it needs to enter from the steel wire inlet and then extend from the steel wire outlet. Therefore, before each use, the steel wire needs to be connected to the steel wire inlet, manually punched, and then the steel wire is continuously pushed to pass through the arc tube. The arc tube as a whole has an arc-shaped structure. When the steel wire passes through the inside of the arc tube, it will not only encounter resistance, but the front end of the steel wire will also cause wear to the inner wall of the arc tube, affecting the service life of the steel wire guide. In order to simplify the steps required for placing the steel wire and avoid wear on the inner wall of the arc tube to increase the service life of the steel wire guide, we propose a steel wire guide for orthopedic surgery.

[0017] The working principle and beneficial effects of the present invention are:

[0018] 1. By setting a placement mechanism, before using the wire guide, the wire is first stretched to make the wire pass through the wire groove to the top of the main conduit, and then the worm is rotated to drive the worm wheel to rotate, and the rotation of the worm wheel drives the rotating shaft to rotate. The rotation of the rotating shaft can drive the auxiliary conduit as a whole to rotate with the rotating shaft as the center of the circle, until the auxiliary conduit and the main conduit are completely attached to form a complete arc-shaped pipeline, so that the user can use the wire guide. In this process, the auxiliary conduit is driven to stick to the main conduit to form a complete arc-shaped pipeline, and the wire is placed between the auxiliary conduit and the main conduit. After the auxiliary conduit and the main conduit are closed, the placement operation is completed, avoiding the need to manually perforate the wire, significantly simplifying the steps required for placing the wire, and in this process, the front end of the wire does not contact the arc-shaped pipeline, and the tip of the wire can also be prevented from scratching the inner wall of the pipeline and causing wear, thereby improving the service life of the wire guide;

[0019] 2. By setting a fixing mechanism, before driving the secondary guide tube to stick to the main guide tube, the steel wire is first stretched to pull the front end of the steel wire over the surface of the guide part, and then the secondary guide tube can be driven to stick to the main guide tube. In this process, the secondary guide tube first contacts the driving rod and pushes the driving rod to move in the direction of the moving slide groove. The movement of the driving rod drives the moving slide plate to move. The movement of the moving slide plate drives the rack to move upward through the restriction of the limiting slide groove on the limiting slide block, and drives the half gear to rotate clockwise. The rotation of the half gear drives the connecting shaft to rotate. The rotation of the connecting shaft drives the turntable to rotate. The rotation of the turntable can drive the guide part to rotate. While the guide part itself rotates clockwise with the turntable as the center, the fixing part at the bottom squeezes the front end of the steel wire against the inner wall of the main placement groove from bottom to top. This can prevent the user from moving the steel wire in the main placement groove during the use of the steel wire guide, thereby interfering with the user's normal use of the guide.

[0020] 3. By setting an unlocking mechanism, when the user guides the steel wire to a predetermined position through the steel wire guide, the user can press the spur gear to drive the connecting rod to move downward, and the connecting rod moves downward to drive the outer rectangular rod to move downward, and the outer rectangular rod moves downward to drive the pull rope to pull downward. At this time, the top of the pull rope can pull the rack and the half gear apart, thereby releasing the limit on the function board, making it easier for the user to pull out the steel wire for use;

[0021] 4. By providing spur gears and tooth grooves, when the user guides the wire through the wire guide, the mutual engagement between the spur gears and the tooth grooves can prevent the user or external tissue structure from contacting the spur gears, causing the spur gears to rotate and causing the wire at the front end of the main guide tube to loosen, thereby ensuring the reliability of the wire guide during use.

[0037] First, before using the wire guide, the wire is stretched so that it passes through the wire groove 2 to the top of the main conduit 301, and then the worm gear 303 is driven to rotate by rotating the worm 306. The rotation of the worm gear 303 drives the rotating shaft 305 to rotate. The rotation of the rotating shaft 305 can drive the auxiliary conduit 302 to rotate as a whole with the rotating shaft 305 as the center of the circle until the auxiliary conduit 302 and the main conduit 301 are completely fitted to form a complete arc-shaped pipeline, so that the user can use the wire guide.

In this process, the secondary conduit 302 first contacts the driving rod 405 and pushes the driving rod 405 to move in the direction of the moving slide groove 407. The movement of the driving rod 405 drives the moving slide plate 409 to move. The moving slide plate 409 moves through the limit slide groove 412 to limit the limit slider 413, drives the rack 416 to move upward, and drives the half gear 414.
