[0002] The effectiveness of medical bandages is crucial for a patient's subsequent recovery. Most bandage procedures rely on the operator to tighten the bandage to close the slipknot. This tightening method requires the operator to provide a stable pulling force, but in practice, it is difficult to maintain a stable pulling force, resulting in inconsistent tightening effects of the bone bandage.

[0027] Please see Figure 1 and Figure 6 The cable tensioner provided by the present invention includes:
[0028] The main body 1 is used for inserting the two ends of a strap with a slipknot and for restricting the slipknot;
[0029] The pushing component 2 is movably assembled inside the main body 1, and is used to be in a compressed state under the action of the driving force and the force of the strap, and the elastic force generated during compression makes the pushing component 2 and the driving component 3 in a stable state.
[0030] The driving component 3, assembled on the pushing component 2, is used to provide driving force to pull the strap to tighten the slip knot.
[0031] Understandably, the strap can be a bone strap, or other types of straps used in the industry. First, the bone strap is tied with a slipknot at a preset position on the bone. The slipknot can be achieved by using a bone-piercing device. After the slipknot is tied, both ends of the bone strap can be inserted into the main body 1, and the slipknot is restricted to the outside of the main body 1 and cannot be inserted. Both ends of the bone strap extend to the driving member 3. The driving member 3 pulls the two ends of the bone strap to tighten the slipknot. During the tightening process, the pushing member 2 will be compressed under the tension of the bone strap, and the pushing member 2 will keep the driving member 3 in a stable state so that the bone strap is in a stable and tight state.
[0032] Please see Figure 1 and Figure 5 In some embodiments, the main body 1 includes a push rod 101 and a housing 102. The push rod 101 is mounted on the housing 102. A wire-passing cavity 101a is provided inside the push rod 101. A wire groove 102a and an assembly cavity are provided inside the housing 102. A notch 102b is also provided on the housing 102. The notch 102b communicates with the wire groove 102a and the assembly cavity, so that the push member 2 can be movably assembled in the assembly cavity.
[0033] It is understood that the push rod 101 can be embedded in the end of the outer shell or fixed by a pin. The two ends of the bone bandage can be inserted into the threading cavity, and then the two ends can pass through the notch 102b and be tightened in the thread groove 102a. The pushing member 2 can slide along the assembly cavity. The pushing member 2 slides in the assembly cavity under the tension of the bone bandage by the driving member 3. The main body 1 of this structure facilitates the insertion and fixation of the bone bandage.
[0034] Please see Figure 4 In some embodiments, the top rod 101 includes a rod body and a partition plate 101b. A groove is provided in the rod body, and the partition plate 101b is assembled in the groove to divide the groove into threading cavities 101a for the two ends of the binding strap for the slip knot to be inserted into. The rod body is also provided with a threading outlet 101c communicating with the threading cavity. The rod body is assembled in the thread groove 102a.
[0035] Understandably, the end of the rod can be beveled, and the partition plate can divide the groove into two threading cavities 101a. The two ends of the bone bandage are respectively inserted into one threading cavity 101a, while the partition plate 101b restricts the slipknot outside the threading cavity 101a. Then, the two ends of the bone bandage pass through the outlet 101c and are then tightly closed in the groove 102a. The outlet 101c can also be an inclined outlet. The rod can be connected and fixed to the outer shell by a pin. The top rod 101 of this structure facilitates the insertion of the bone bandage.
[0036] Please see Figure 2In some embodiments, the pushing component 2 includes a push rod 201 and an elastic element 202. The push rod 201 is movably assembled in the assembly cavity, the elastic element 202 is located in the assembly cavity, and the elastic element 202 is connected between the push rod 201 and the inner wall of the assembly cavity. The driving component 3 is assembled on the push rod 201.
[0037] Understandably, the slipknot of the bone bandage can be tightened under the pulling force of the driving member 3. During the tightening process, the partition plate 101b restricts the movement of the slipknot, while the two ends of the bone bandage are tightened, thereby achieving the tightening of the slipknot. The driving member 3 is set on the pushing member 2. When tightening, the pushing member 2 will also move under the pulling force of the bone bandage. The pushing member 2 will provide a force opposite to the tightening force. Under the action of this reaction force, the tightened state is kept stable. Several insertion holes can also be provided on the outer shell 102. Limiting screws are inserted into the insertion holes to limit the movement distance of the push rod 201, thereby providing a safe tension distance.
[0038] Please see Figure 1 In some embodiments, the pushing member 2 further includes a guide rod, which is connected to the push rod 201 and is movably assembled in the groove 102a.
[0039] Understandably, the upper part of the wire groove 102a can be used to tighten the bone strap, and there is still some space in the lower part of the wire groove. The guide rod can effectively improve the stability of the sliding of the pushing component 2. The push rod 201 of the pushing component 2 can also be equipped with scale lines, which can make it easy to understand the degree of tightening.
[0040] Please see Figure 1 and Figure 3 In some embodiments, the drive member 3 includes a ratchet lever member 301 and a pawl. The ratchet lever member 301 is rotatably mounted on the push member 2, and the pawl is oscillatingly mounted on the push member 2. The pawl and the ratchet lever member 301 are engaged in a ratchet-like manner.
[0041] It is understood that the ratchet lever component 301 may include a ratchet and a rotating lever. The push lever 301 may have a through cavity. The ratchet may be rotatably mounted within the through cavity of the push component via the rotating lever. The end of the bone bandage extends to the surface of the ratchet. Reversing the rotating lever causes the ratchet to rotate. The ratchet, relying on the friction of its surface, pulls the bone bandage during forward rotation. It can also cooperate with the pawl to pull the bone bandage, tightening the slip knot. During this rotation, the pawl will not get stuck in the ratchet's tooth groove, thus preventing the ratchet from engaging. The pawl will not interfere with the rotation of the ratchet. When it rotates in the opposite direction, the pawl will restrict the rotation of the ratchet, thereby preventing the ratchet from rotating in the opposite direction. Under the elastic force of the elastic element 202, the pawl can be better engaged in the tooth groove, preventing the ratchet from rotating in the opposite direction, thereby improving the stability of the drive component 3 and also improving the stability during tightening. The pawl may include a pawl body 304, a swing shaft, and a spring 303. The pawl body 304 is assembled in the through cavity through the swing shaft. One end of the pawl body 304 abuts in the tooth groove, and the other end of the pawl body 304 is connected to the inner wall of the through cavity through the spring 303.
[0042] Please see Figure 1 In some embodiments, the drive component 3 further includes a ratchet handle 302, which is fixedly connected to the ratchet lever component 301.
[0043] Understandably, one can hold the ratchet handle 302 to rotate the ratchet lever component, and the ratchet handle 302 can easily rotate the ratchet lever component 301.
[0044] As described above, the cord tensioner provided by the present invention pulls the cord with the drive member 3 to tighten the slip knot to a preset position. After tightening to the preset position, the drive member 3 is kept in a stable state by pushing the member 2, so that the slip knot is in a stable tightened state and the tightening effect is stable.
[0045] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
