DETAILED DESCRIPTION

[0018] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0019] The structure of the present invention is described in detail below in conjunction with the accompanying drawings.

[0020] See also Figures 1 to 11 A medical cable tightener for orthopedic surgery provided by an embodiment of the present invention comprises a front end bracket 1, a bracket main body rod 2 is fixedly connected to the back of the front end bracket 1, and a left leg 3 and a right leg 4 are fixedly connected to the front of the front end bracket 1; a first slide 5 is provided in the bracket main body rod 2, and a first cable guide groove 6 is provided in both the left leg 3 and the right leg 4, and the first cable guide groove 6 is connected to the first slide 5; a screw rod 7 is installed in the first slide 5; a bearing sliding platform 8 is sleeved on the screw rod 7, and the bearing sliding platform 8 is threadedly connected to the screw rod 7, and cable locking components are installed on both sides of the bearing sliding platform 8.

[0021] Adopt the above scheme: when using, after the fracture part is tied up with the cable, when the cable needs to be tightened, at this time, take the bidirectional tightening cable as an example, as follows: First, the screw rod 7 rotates to drive the bearing sliding platform 8 to move in the first slide 5 and gradually approach one side of the front end bracket 1. When the bearing sliding platform 8 moves to a suitable position, the staff will pass the left and right ends of the cable to be tightened through the first cable guide groove 6 respectively until one end of the cable enters the first slide 5. Then the staff will introduce the cables in the first slide 5 into the bearing sliding platform 8 respectively, and then make the cables on the bearing sliding platform 8 contact with the cable locking assembly, and rotate the cable locking assembly at the same time. When the cable locking assembly rotates, the cable will be rolled into the cable locking assembly, and then the cable will be locked. Then the screw rod 7 is driven to reverse and drive the bearing sliding platform 8 to slide and move away from the front end bracket 1. At this time, the bearing sliding platform 8 will tighten the cable when it moves in the opposite direction, thereby achieving a tightening effect, thereby achieving the purpose of tightening the cable in both directions.

[0022] It should be noted that: first, if it is necessary to use a one-way cable tightening method, the operation process is different from the two-way method in that only one end of the cable needs to be passed through one of the first cable guide grooves 6 of the left leg 3 or the right leg 4 into the first slideway 5. As for how to fix and tighten the one-way cable, it is the same as described above. Second, since the first guide groove is winding, when the cable is tightened in the first guide groove, it can buffer and disperse the tension, thereby preventing the cable from being damaged due to excessive concentrated force. Third, since the first cable guide grooves 6 are respectively opened in the left leg 3 and the right leg 4, the cable can be tightened in both directions at the same time.

[0023] Furthermore, a first rotating rod 9 is installed in each of the first cable guiding grooves 6 ; a first driving wheel 10 is installed on the outer surface of the first rotating rod 9 , and a first groove which can match the diameter of the cable is formed on the surface of the first driving wheel 10 .

[0024] The above solution is adopted: when in use, when it is necessary to introduce the cable into the first cable guide groove 6, when the staff introduces one end of the cable into the first cable guide groove 6, the cable contacts the first driving wheel 10, thereby driving the first rotating rod 9 and the first driving wheel 10 to rotate. This rotation action will act on the cable to achieve the tightening or loosening of the cable, effectively preventing the cable from getting stuck at the angle position, and ensuring that the cable passes through the first cable guide groove 6 smoothly. In addition, the first groove on the first driving wheel 10 that is adapted to the diameter of the cable ensures that the cable always remains in the first groove during the tightening or loosening process, preventing the cable from being separated from the first cable guide groove 6 or getting entangled.

[0025] Furthermore, two symmetrical second cable guiding grooves 11 are provided in the carrying sliding platform 8 .

[0026] Furthermore, the cable locking assembly includes a first rotating shaft 12, which is rotatably connected to the supporting sliding platform 8; a second driving wheel 13 is fixedly connected to the outer surface of the first rotating shaft 12, and a second groove that can adapt to the cable diameter is opened on the outer surface of the second driving wheel 13, and a cable fixing hole 14 is opened on the second groove; a first toggle rod 15 is fixedly connected to the upper end of the first rotating shaft 12.

[0027] The above scheme is adopted: during use, when the cable enters the first slide 5, the staff is required to introduce the cables in the first slide 5 into the second cable guide groove 11 respectively, and then insert the cables into the cable fixing hole 14 through the second cable guide groove 11. Before this, the position of the cable fixing hole 14 needs to be aligned with the second cable guide groove 11. Since the cable fixing hole 14 and the second cable guide groove 11 are also arc-shaped, after the cable is inserted into the cable fixing groove, the staff is required to rotate the first toggle rod 15 so that the first toggle rod 15 drives the first rotating shaft 12 to rotate synchronously, and the first rotating shaft 12 will drive the second driving wheel 13 to rotate synchronously when rotating. Since the cable is already located in the cable fixing hole 14, the second driving wheel 13 will roll the cable into the second driving wheel 13 when rotating. At this time, the tension of the cable will be increased, and the second driving wheel 13 will be fixed to achieve cable locking, and then the screw rod 7 will be driven to move the bearing sliding platform 8 in the opposite direction to further tighten the cable.

[0028] It should be noted that when the cable is rolled into the second driving wheel 13 , the cable will be placed in the second groove to prevent the cable from being separated from the second driving wheel 13 .

[0029] Furthermore, a sealing ring 16 is installed on one side of the first cable guiding groove 6 close to the first driving wheel 10 .

[0030] Furthermore, a first cavity is opened in the front end bracket 1, and the first cavity extends into the left leg 3 and the right leg 4; an elastic airbag 18 is installed in the first cavity, and a first hose 19 is installed between the elastic airbag 18 and the first cable guide groove 6; a first channel symmetrically arranged in the upper and lower parts is opened in the front end bracket 1, and the two ends of the first channel are respectively connected to the first slide 5 and the first cavity; a first connecting rod 20 is installed in the first channel, one end of the first connecting rod 20 can contact the elastic airbag 18, and the other end of the first connecting rod 20 is fixedly connected to the load-bearing sliding platform 8.

[0031] The above scheme is adopted: when in use, when the screw rod 7 drives the bearing sliding platform 8 to approach and move toward the front end bracket 1, the bearing sliding platform 8 will drive the first connecting rod 20 to enter the first channel, and when the first connecting rod 20 moves to the preset position, it will contact one side of the elastic airbag 18. At this time, if the first connecting rod 20 continues to move, the first connecting rod 20 will squeeze the elastic airbag 18, so that the elastic airbag 18 is gradually compressed, and when the elastic airbag 18 is in a compressed state, the liquid inside will be transported to the two first cable guide grooves 6 through the first hose 19 respectively. When the cable passes through the first cable guide groove 6, it will contact the liquid. In this process, after the cable passes through the first cable guide groove 6 with liquid, the liquid will assist the cable to move in the first cable guide groove 6, effectively preventing the cable from moving smoothly in the first cable guide groove 6, thereby causing the cable to be stuck.

[0032] It should be noted that: first, sealing rings 16 are installed at both ends of the first cable guide groove 6 to prevent liquid from flowing out of the first cable guide groove 6 when the cable enters the first cable guide groove 6. Second, the side of the elastic airbag 18 in contact with the first connecting rod 20 is a hard material, and the opposite side is also a hard material. Third, if a one-way tightening cable is used, the cable will enter one of the cable guide grooves at this time, then it is only necessary to allow the liquid to enter the groove through one of the first hoses 19, and the other first hose 19 will be in a closed state, which can be adjusted according to actual needs. Sixth, a circular hole can be opened on one side of the elastic airbag 18, and liquid can be injected into the elastic airbag 18 through the circular hole. A one-way valve can also be installed in the circular hole to control the injection and outflow of the liquid, and the injected liquid is quantitative, and this liquid is a lubricating liquid.

[0033] Furthermore, an end of the outer surface of the screw rod 7 away from the bracket main rod 2 is fixedly connected to a first gear 21, a second gear 22 is meshed on one side of the first gear 21, an axial portion of the second gear 22 is fixedly connected to a second rotating shaft, and one end of the second rotating shaft is fixedly connected to a first driving rod 23.

[0034] The above scheme is adopted: during use, when the screw rod 7 needs to be rotated, the staff will turn the first driving rod 23, and this action will drive the second rotating shaft to rotate, and then drive the second gear 22 to rotate. Due to the meshing relationship between the first gear 21 and the second gear 22, the rotation of the second gear 22 will synchronously drive the first gear 21 to rotate, and finally the screw rod 7 will rotate with the rotation of the first gear 21, thereby ensuring the accuracy and stability of the rotation of the screw rod 7.

[0035] It should be noted that: first, the screw rod 7 can be rotated forward or reversely by operating the first driving rod 23 to rotate clockwise or counterclockwise. Second, since the diameter of the second gear 22 is smaller than that of the first gear 21, when the second gear 22 drives the first gear 21 to rotate, the speed of the first gear 21 will be increased.

[0036] Furthermore, a plurality of first fixing holes 27 are provided on the surface of the supporting sliding platform 8 close to the second driving wheel 13, and a plurality of second fixing holes 24 that can be aligned with the first fixing holes 27 are provided on the second driving wheel 13. A positioning pin 25 is installed in the second fixing hole 24, and one end of the positioning pin 25 can extend into the first fixing hole 27.

[0037] The above solution is adopted: during use, when the cable has been wound into the second driving wheel 13 and the second driving wheel 13 needs to be fixed, the staff will accurately align the second fixing hole 24 on the second driving wheel 13 with the first fixing hole 27 on the carrying sliding platform 8, and then insert and push the positioning pin 25 until the positioning pin 25 completely passes through the second fixing hole 24 and is firmly embedded in the first fixing hole 27, thereby achieving a firm fixation of the second driving wheel 13 and ensuring the stability of the second driving wheel 13 during the fixing process.

[0038] Furthermore, a third fixing hole 26 which can be aligned with the cable fixing hole 14 is formed on the positioning pin 25 , and the third fixing hole 26 can be communicated with the cable fixing hole 14 .

[0039] The above scheme is adopted: when in use, when the cable coated with oil needs to be rolled into the second driving wheel 13, the cable is first located in the cable fixing hole 14, and then one end of the cable is passed through the third fixing hole 26, and the positioning pin 25 is rotated, and the positioning pin 25 will gradually be screwed into the first fixing hole 27. During this process, the positioning pin 25 will cause the cable to be wound around the positioning pin 25 and fix the second driving wheel 13, and then drive the supporting sliding platform 8 to move in the opposite direction to tighten the cable.

[0040] You can tighten the cable by any of the following methods, for example: First, after inserting the locating pin 25 into the first fixing hole 27, the cable is passed through the third fixing hole 26, and then the locating pin 25 is rotated to wrap the cable around the locating pin 25, and the locating pin 25 is rotated and screwed into the first fixing hole 27, and then the carrying sliding platform 8 is driven to move in the opposite direction to tighten the cable. When it moves to a certain distance, if the appropriate tightening force is not reached, the locating pin 25 can be screwed out of the first fixing hole 27, but not out of the second fixing hole 24. At this time, the second driving wheel 13 is driven to rotate, and the cable is rolled onto the second driving wheel 13.

[0041] Secondly, of course, after the cable is wound around the positioning pin 25, the second driving wheel 13 is driven to rotate so that the cable is wound around the second driving wheel 13, and then the positioning pin 25 is inserted into the first fixing hole 27, and the load-bearing sliding platform 8 is driven to move in the opposite direction to tighten the cable.

[0042] It should be noted that: by opening a cavity inside the second driving wheel 13 , when the cable is wound around the positioning pin 25 , it will be wound in the cavity.

[0043] Furthermore, anti-slip portions are provided on surfaces of the first toggle rod 15 and the first driving rod 23 .

[0044] Working principle of the present invention: First, the screw rod 7 is rotated to cause the bearing slide 8 to move along the first slide 5 toward one side of the front bracket 1. After the bearing slide 8 reaches the appropriate position, the staff passes the two ends of the cable through the first cable guide groove 6 respectively to ensure that one end of the cable completely enters the first slide 5. Then, the cable is introduced into the corresponding position of the bearing slide 8 and the cable is brought into contact with the cable locking assembly. The cable locking assembly is rotated so that it rolls the cable inside to achieve locking. Next, the screw rod 7 is reversed to move the bearing slide 8 backward and away from the front bracket 1. In this process, the movement of the bearing slide 8 will tighten the cable, thereby achieving a tightening effect and realizing the operation of tightening the cable in both directions.

[0045] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
