At the same time, it has also been widely used in trauma orthopedics.

[0003] The end of the wire anchor is provided with a wire hole for passing the suture. However, in the prior art, the wire hole of the wire anchor that has undergone preliminary processing has burrs on its inner surface, especially at the contour position. The suture is easily broken after contact and friction with the rough part in the wire hole, causing a safety hazard. Currently, the grinding of the wire anchor is mainly carried out by reciprocating rubbing of the grinding wire, but products of different sizes and different wire holes need to adapt to different grinding angles. Therefore, a guide mechanism for adjusting the angle of the grinding wire is required. Utility Model Content

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] It should be understood that although the terms upper, middle, lower, top, end, etc. appear in this article to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish elements from each other for easy understanding, and are not used to define any direction or order limitation.

[0030] like Figure 1-7 As shown, a grinding wire guide mechanism is applied to a micro-hole slot intelligent testing integrated device with a wire anchor, comprising a fixture 1 for fixing the wire anchor 2, an angle adjustment module and an upper constraint module sequentially arranged above the fixture 1;

[0031] The upper constraint module includes two guide modules arranged on both sides of the fixture 1. The guide modules guide the grinding wire 5 to enter and pass through the hole slot 2.1 with the wire anchor 2. The grinding wire 5 forms a symmetrical tensioning section 5.1 between the two guide modules and the hole slot 2.1, wherein the grinding wire 5 is tensioned in a roughly U-shaped posture. Figure 1 , 6 ,7 at the dotted line;

[0032] The angle adjustment module includes a cantilever 3 rotatably arranged on both sides of the fixture 1, and an adjusting wheel 4 arranged on the cantilever 3. The cantilever 3 is specifically arranged on both sides above the fixture 1 relatively to adjust the tensioning section 5.1 between the guide module and the wire anchor 2, wherein the adjusting wheel 4 constrains and overlaps on both sides of the tensioning section 5.1, and the cantilever 3 rotates and drives the adjusting wheel 4 away from or close to the tensioning section 5.1 to release or constrain the grinding wire 5 to both sides.

[0033] Preferably, both the guide module and the upper constraint module are provided with pulley components for overlapping with the grinding line 5 .

[0034] Specifically, the cantilever 3 is relatively arranged on both sides of the central axis of the tensioning section 5.1, and the tensioning section 5.1 forms a grinding angle between the two adjusting wheels 4 and the hole groove 2.1. The guide module and the upper constraint module located above the adjusting wheel 4 are both arranged on both sides of the central axis of the tensioning section 5.1. By adjusting the relative angle of the cantilever 3, the grinding angle of the grinding line 5 is controlled to cope with the hole grooves 2.1 of different angles and different calibers.

[0035] As a further implementation of the grinding wire 5, before the angle adjustment process is performed on the grinding wire 5, the grinding wire 5 is in a non-grinding state. Optionally, the upper ends of the grinding wire 5 are fixed.

[0036] from Figure 1 and Figure 3 It can be seen that as an implementation method for the grinding line 5, the upper constraint module also includes a relatively arranged clamping module 13, and a lifting module 14 that drives the clamping module 13 to move up and down alternately. The two ends of the tensioning section 5.1 are fixed on the clamping module 13. After completing the angle adjustment of the tensioning section 5.1, the clamping module 13 fixes and maintains the grinding line 5 with the current tensioning force, and then the lifting module 14 drives the clamping module 13 to move up and down alternately, thereby realizing the grinding action.

[0037] Among them, the clamping module 13 is provided with a front guide wheel 13.1 and a rear guide wheel 13.2 corresponding to the lead-in end and the lead-out end of the grinding line 5. The number of the clamping module 13 and the lifting module 14 is two, and they are symmetrically arranged about the central axis of the tensioning section 5.1.

[0038] Preferably, the clamping module 13 is selected as a finger cylinder 13.3, and a clamping block is provided on the action end of the finger cylinder 13.3.

[0039] As an option, the lifting module 14 is a servo electric cylinder for vertical linear movement;

[0040] like Figure 2 As shown, specifically, the guiding module includes a limiting wheel set 6 arranged above the adjusting wheel 4, the grinding line 5 is passed through the limiting wheel set 6, and the limiting distance D1 formed between the two limiting wheel sets 6 is greater than the constraint distance D2 formed between the adjusting wheels 4.

[0041] The number of the limiting wheel set 6 is two adjacent wheel units, and the grinding line 5 is limited between the two wheel units.

[0042] In this embodiment, the limit spacing D1 is defined by two limit wheel groups 6, and the maximum constraint spacing D2 of the cantilever 3 is smaller than the limit spacing D1, thereby ensuring that the adjusting wheel 4 on the cantilever 3 is located in the area capable of constraining and releasing the tensioning section 5.1, thereby controlling the angle of the tensioning section 5.1 when the cantilever 3 is away from or close to the grinding section.

[0043] like Figure 1 and Figure 7As shown, specifically, the rotation position of the cantilever 3 is located between the limiting wheel group 6 and the adjusting wheel 4, and the adjusting wheel 4 has a constraint stroke approaching toward the top of the belt-wire anchor 2 as the cantilever 3 rotates, and a release stroke away from the lower sides of the belt-wire anchor 2, so that during the constraint process, the tensioning segment 5.1 is controlled to be an elongated U-shaped posture to adapt to the small-diameter hole slot 2.1, and during the release process, the tensioning segment 5.1 is controlled to be an expanded U-shaped posture to adapt to the large-diameter hole slot 2.1.

[0044] As a further implementation of the angle adjustment module, it also includes a vertically arranged tooling plate 15, and the cantilever 3 is rotatably arranged on the tooling plate 15. The angle adjustment module includes an actuator 7 for driving the cantilever 3 to rotate, and the cantilever 3 is driven to rotate by the movement of the actuator 7, wherein the actuator 7 can be selected as a servo electric cylinder, so as to accurately control the relative angle of the two cantilevers 3.

[0045] Optionally, the limiting wheel set 6 is fixedly arranged.

[0046] Preferably, the limiting wheel set 6 is arranged to move synchronously with the execution member 7 to further optimize the control effect on the posture of the tensioning section 5.1.

[0047] As a further explanation of the actuator 7, the angle adjustment module includes an actuator 7, which is arranged on the central axis of the tensioning section 5.1. The actuator 7 is arranged to move linearly, and the movement trajectory of the actuator 7 is collinear with the central axis of the tensioning section 5.1.

[0048] Fixed columns 8 are provided on both sides of the actuator 7 on the tooling plate 15, the cantilever 3 is arranged in a V shape, the middle part of the cantilever 3 is rotatably arranged on the rotating column, and one end of the cantilever 3 cooperates with the actuator 7 and is actuated to rotate, and the adjusting wheel 4 is arranged at the other end of the cantilever 3.

[0049] Specifically, a fixing is provided on the top of the fixture 1, a mounting plate 7.2 is provided on the actuator 7, a guide column 7.1 is provided on the mounting plate 7.2, and a slide groove 3.1 is provided on the cantilever 3, the guide column 7.1 is passed through the slide groove 3.1, so that the two relative cantilevers 3 are arranged together on the guide column 7.1, and the relative angle of the cantilever 3 is limited by the slide groove 3.1.

[0050] Thanks to the actuator 7 in this embodiment, the tension of the grinding wire 5 can be further adjusted by the action of the actuator 7. A tension and compression sensor is connected to the bottom of the fixture. The tension can be fed back through the tension and compression sensor, thereby accurately adjusting to the expected tension.

[0051] As an implementation method in which the limiting wheel set 6 and the actuating member 7 move synchronously, the limiting wheel set 6 is arranged on the mounting plate 7.2.

[0052] The grinding wire 5 enters the limiting wheel group 6 on the right through the clamping module 13 on the right, and overlaps downward on the inner side of the adjusting wheel 4 on the right, then passes downward through the hole groove 2.1 with the wire anchor 2 and overlaps upward to the adjusting wheel 4 on the left, and then passes upward into the limiting wheel group 6 on the left, and is led out through the clamping module 13 on the left, wherein the two ends of the grinding wire 5 are respectively connected to the pay-off module 11 and the winding module 12, the pay-off module 11 is located on the right, and the winding module 12 is located on the left.

[0053] Continue to refer to Figure 2 In other embodiments, in order to improve the reliability of the grinding work, the guide module also includes a guide wheel 9 and a lead block 10 arranged below the guide wheel 9. The guide wheel 9 and the lead block 10 are fixed to the tooling plate 15 through a column. The guide wheel 9 is preferably arranged above the limiting wheel group 6. The number of guide wheels 9 and lead blocks 10 is two, and they are located on both sides of the central axis of the tensioning section 5.1. The lead block 10 is provided with a wire passing channel 10.1, which is arranged between the guide wheel 9 and the limiting wheel group 6. The grinding wire 5 is further guided by the guide wheel 9 and the wire passing channel 10.1 to reduce the risk of the grinding wire 5 breaking.

[0054] Preferably, the wire passage 10 . 1 is arranged close to the center axis of the tensioning section 5 . 1 relative to the guide wheel 9 , so as to guide the grinding wire 5 in transition.

[0055] Among them, after the grinding wire 5 is led out from the clamping module 13 on the right, it first abuts against the guide wheel 9 on the right, enters the wire passing channel 10.1 on the right, passes through the limiting wheel group 6, and then passes out from the limiting wheel group 6 on the left. It is introduced into the wire passing channel 10.1 on the left from bottom to top, and is overlapped with the guide wheel 9 on the left and then connected to the clamping module 13.

[0056] Specifically, a wire break sensor is provided on the lead block 10, so as to monitor the working condition of the grinding wire 5 in real time during the grinding process.

[0057] like Figure 4 and Figure 5 As shown, specifically, a pay-off module 11 is provided at the line input end of the upper constraint module, and a winding module 12 is provided at the line output end of the upper constraint module. The grinding wire 5 is introduced from the pay-off module 11 to the hole groove 2.1 through a guiding module, and is introduced into the winding module 12 through another guiding module. The end of the grinding wire 5 is fixed on the winding module 12.

[0058] Among them, the pay-off module 11 is arranged on the right side of the tooling plate 15, including a rotatable pay-off wheel 11.1, and a guide column 11.2 and two pay-off wheels 11.3 are arranged in sequence toward the central axis. The grinding wire 5 is paid out from the pay-off wheel 11.1 and passes through the guide column 11.2 and then penetrates between the two pay-off wheels 11.3, and then enters the clamping module 13 on the right.

[0059] Among them, the winding module 12 is arranged on the bottom left side of the tooling plate 15, including a side lead column 12.1, a winding wheel 12.2, and a winding servo electric cylinder 12.3 that are sequentially arranged to the left. During the lead-in process, the grinding wire 5 is fixed and knotted on the winding wheel 12.2, and a plurality of side lead holes are provided on the side lead house, and at least one side lead hole is close to the tangent of the winding wheel 12.2.

[0060] In the utility model, the grinding wire 5 is guided from above the wire anchor 2 and passes through the hole groove 2.1 on the wire anchor 2 by the upper constraint module and the guide module. During the grinding process, the grinding wire 5 acts on the hole groove 2.1 of the wire anchor 2 in a tensioned U-shaped posture. Before the grinding process, the adjusting wheels 4 on the two opposite cantilevers 3 are used to constrain the two sides of the tensioning section 5.1 on the grinding wire 5, so as to control the grinding angle of the grinding wire 5. By adjusting the relative position of the two cantilevers 3, when the adjusting wheel 4 is away from the tensioning section 5.1, the tensioning section 5.1 is released to expand the grinding angle, and when the adjusting wheel 4 is close to the tensioning section 5.1, the tensioning section 5.1 is acted toward the central axis to reduce the grinding angle.

[0061] In other embodiments, after the grinding work is completed, the hole groove of the wire anchor is further inspected by the above-mentioned clamping module, and the grinding wire is fixed by the left and right clamping modules and lifted to a predetermined height to detect the working performance of the wire anchor under a predetermined tensile pressure.

[0062] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
