Description
Technical Field
[0001] This invention relates to the field of acromioclavicular joint reduction technology, and in particular to an auxiliary device for coracoid process alignment and clavicle drilling positioning. Background Technology
[0002] Acromioclavicular joint dislocation is a common shoulder injury. Currently, the commonly used treatment methods in clinical practice include clavicle hook plate fixation and coracoid process drilling loop fixation. In addition, arthroscopic-assisted techniques can be used. Arthroscopic-assisted techniques repair acromioclavicular joint fractures and dislocations by using sutures to wrap around the base of the coracoid process and pulling out loops at the supraclavicular drilling site under arthroscopic guidance. These techniques have the advantages of being less invasive and allowing for faster recovery.
[0003] However, the aforementioned prior art has the following drawbacks:
[0004] Clavicle hook plate fixation and coracoid process drilling and loop fixation carry significant risks of damage and coracoid process rupture. Under arthroscopic guidance, sutures are used to wrap around the base of the coracoid process, and loops are pulled out at the supraclavicular drilling site to repair acromioclavicular joint fracture-dislocation. Due to interference from soft tissue and bleeding, the suture passing under the coracoid process is slow and cannot be completed in time, which prolongs the operation time and increases the intraoperative infection rate.
[0005] Therefore, in order to solve the above problems, the present invention proposes a coracoid process drilling and clavicle drilling positioning auxiliary device that can avoid drilling holes in the coracoid process and shorten the operation time. Summary of the Invention

[0030] The following description is intended to provide a detailed account of the invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.
[0031] Please see Figure 1 This invention provides a technical solution: a coracoid process crossing line and clavicle drilling positioning auxiliary device, wherein the two sides along the length of the clavicle are the sternal side a and the shoulder joint side b, respectively, comprising:
[0032] A clavicle positioning component 100 is provided, which is arranged along the length of the clavicle. The clavicle positioning component 100 has a positioning hole 101 on the side facing the clavicle. The clavicle positioning component 100 is configured to drill and position the clavicle through the positioning hole 101. Preferably, the positioning hole 101 is inclined, and the height of the positioning hole 101 gradually increases as it approaches the clavicle. By tilting the positioning hole 101, the suture is not made to form an angle with the lower exit edge of the positioning hole 101 after the drill is inserted, so as not to cut the suture.
[0033] The suture assembly 200 includes a suture body 201 connected below the clavicle positioning member 100. The suture body 201 has an arc-shaped opening structure. The arc-shaped inner side of the suture body 201 forms a coracoid process receiving area 201a. The opening 201b of the receiving area 201a faces the sternal side a. The suture body 201 has a suture channel 2011 inside. The first port 2011a of the suture channel 2011 faces the clavicle positioning member 100, and the second port 2011b of the suture channel 2011 is located on the side of the opening 201b away from the clavicle positioning member 100.
[0034] The take-up assembly 300 has a wire outlet hole 202 vertically opened on the side of the wire guide body 201 opening 201b near the clavicle positioning member 100. The take-up assembly 300 is configured to move along the axis of the wire outlet hole 202. The take-up assembly 300 is provided with a clamping member 301, which is provided corresponding to the second port 2011b. The clamping member 301 is configured to fix the wire when it passes through the second port 2011b. The clamping member 301 is also configured to pass through the take-up assembly 300 through the wire outlet hole 202.
[0035] In use, the clavicle positioning component 100, the thread guiding component 200, and the thread take-up component 300 can be combined. The clavicle is drilled and positioned using the positioning hole 101 on the clavicle positioning component 100. The thread guiding body 201 is fitted onto the outside of the coracoid process through the opening 201b. The thread is then passed through the first port 2011a of the threading channel 2011. Guided by the threading channel 2011, the thread passes under the coracoid process and exits through the second port 2011b. The clamping component 300... 01. Fix the thread that has been passed through. Operate the thread take-up assembly 300 to pull out the clamp 301 with the thread fixed from the thread outlet 202. The thread located between the openings 201b closes the receiving area 201a on the thread body 201 to complete the winding of the thread around the coracoid process. This fixes the relative position of the coracoid process and the clavicle above it, avoids drilling the coracoid process, and minimizes secondary stimulation of the soft tissue by the instrument. This can reduce the reoperation rate and the chance of iatrogenic fracture, shorten the operation time to a certain extent, and reduce the intraoperative infection rate.
[0036] Regarding the specific structure of the wire guide assembly 200, the wire guide body 201 is a "C"-shaped wire guide body 201. The inner side of the "C"-shaped wire guide body 201 forms a beak-shaped receiving area 201a. Specifically, the wire guide body 201 includes a first horizontal bar 2012 and a second horizontal bar 2013 arranged vertically from top to bottom at intervals, and a vertical bar 2014 connecting the shoulder joint side b of the first horizontal bar 2012 and the shoulder joint side b of the second horizontal bar 2013. The middle part of the vertical bar 2014 faces the slider 405 on the shoulder joint side b in an arc shape.
[0037] The cable guide assembly 200 also includes a column 203, which is installed vertically above the vertical rod 2014. The surface of the column 203 is provided with a recess 2031 for a built-in pulley, and the pulley is matched with the cable.
[0038] The threading channel 2011 includes a vertical section 2011e and a horizontal section 2011d connected in sequence. The vertical section 2011e is arranged along the length direction of the column 203 and the vertical rod 2014, and the horizontal section 2011d is arranged along the length direction of the second horizontal rod 2013. The first port 2011a of the threading channel 2011 is located in the recess 2031, and the second port 2011b of the threading channel 2011 is located at the end of the second horizontal rod 2013. In use, the wire is threaded through the first port 2011a located in the recess 2031 into the vertical section 2011e of the threading channel 2011. The wire then passes through the vertical section 2011e to the horizontal section 2011d and exits through the second port 2011b. During this process, the outer side of the wire contacts a pulley in the recess 2031. The pulley rotates during the movement of the wire to assist its movement.
[0039] For the specific construction of the take-up assembly 300, please refer to [link / reference]. Figure 2 The clamping member 301 includes a first clamping part 3011 and a second clamping part 3012 arranged sequentially from top to bottom in the vertical direction. (Continue to see...) Figure 4 and 5 The clamping member 301 has at least two working states, namely an initial state and a clamping state. When the clamping member 301 is in the initial state, the first clamping part 3011 and the second clamping part 3012 are spaced apart. When the clamping member 301 is in the clamping state, the first clamping part 3011 and the second clamping part 3012 are in contact. The take-up assembly 300 also includes an operating member 303, which is configured to switch the clamping member 301 from the initial state to the clamping state.
[0040] Specifically, the take-up assembly 300 further includes: a take-up body 302, which is a hollow columnar take-up body 302, and is detachably connected to the inner side of the outlet hole 202. Preferably, the take-up body 302 is threadedly connected to the inner side of the outlet hole 202.
[0041] The inner side of the take-up body 302 is provided with an operating member 303 that can move along the length direction of the take-up body 302. The end of the operating member 303 is connected to the first clamping part 3011. The second clamping part 3012 is placed in the horizontal part 2011d of the threading channel 2011 through the second port 2011b. The horizontal part 2011d of the threading channel 2011 is flush with the inner wall of the side away from the clavicle and the side of the second clamping part 3012 facing the first clamping part 3011. That is, the second clamping part 3012 just enters the horizontal part 2011d and is flush with the bottom surface of the horizontal part 2011d.
[0042] When the second clamping part 3012 is embedded in the "C"-shaped wire take-up body 302, and its position is at the same level as the bottom of its inner wire-passing channel 2011, the wire passes through the wire-passing body 201 from top to bottom, passing through the horizontal part 2011d of the "C"-shaped inner wire-passing channel 2011. Because the upper surface of the second clamping part 3012 and the bottom surface of the horizontal part 2011d of the wire-passing channel 2011 are at the same level at this time, the wire can pass between the second clamping part 3012 and the first clamping part 3011. Further pressing the operating member 303 causes the first clamping part 3011 to press down, and the first clamping part 3011 and the second clamping part 3012 align, thus clamping the first clamping part 3011. The first clamping part 3011 and the second clamping part 3012 clamp the wire. Both the first clamping part 3011 and the second clamping part 3012 are magnets. The magnetic poles on opposite sides of the first clamping part 3011 and the second clamping part 3012 are opposite. An elastic member 3013 is provided between the outer side of the first clamping part 3011 and the outer side of the second clamping part 3012. The elastic member 3013 is configured to provide a spring force to support the first clamping part 3011 and the second clamping part 3012 so that the clamping member 301 remains in its initial state. The spring force of the elastic member 3013 is less than the attraction force generated when the first clamping part 3011 and the second clamping part 3012 come into contact.
[0043] In one embodiment of the present invention, the elastic element 3013 includes at least two connecting rods 30131 sequentially connected between the first clamping part 3011 and the second clamping part 3012. The connecting rods 30131 are connected to each other, between the connecting rods 30131 and the first clamping part 3011, and between the connecting rods 30131 and the second clamping part 3012 by rotating joints. A spring 30132 is provided on the rotating joint. Preferably, the connecting rods 30131 are located on opposite sides of the clamping element 301 in the circumferential direction.
[0044] The operating component 303 is a rod-shaped component. A spring is provided along the length direction between the operating component 303 and the take-up body 302. The operating component 303 is provided with an elastic buckle, one end of which abuts against the inner wall of the take-up body 302. In the direction of movement of the operating component 303, the inner wall of the take-up body 302 is provided with an outlet corresponding to the buckle. In use, when the head end of the operating component 303 is pressed, the end end of the operating component 303 can extend. When the end end of the operating component 303 extends a certain distance, the buckle on the operating component 303 engages with the outlet on the take-up body 302 to constrain the position of the operating component 303 on the take-up body 302. In this embodiment, the connection structure between the operating component 303 and the take-up body 302 is the same as the internal structure of a spring pen in the prior art, which is prior art and will not be described in detail here. In use, the operator can press down the end of the operating member 303 near the clavicle side. The end of the operating member 303 away from the clavicle side can be extended to press down the first clamping part 3011. The first clamping part 3011 moves in a way that approaches the second clamping part 3012, so that the first clamping part 3011 and the second clamping part 3012 fix the wire.
[0045] Furthermore, an infrared sensing mechanism 3014 is provided between the first clamping part 3011 and the second clamping part 3012. The infrared sensing mechanism 3014 can trigger an alarm when it detects the wire passing through. When the wire passes from the first port 2011a to the second port 2011b of the threading channel 2011, the end of the wire passes under the second clamping part 3012. The infrared sensing mechanism 3014 senses this and triggers an alarm. At this time, the doctor separates the wire take-up assembly 300 and the wire passing assembly 200 to complete the subcoracoid suture passing.
[0046] Regarding the specific structure between the clavicle positioning member 100 and the thread guide assembly 200, the thread guide body 201 is movably connected to the lower part of the clavicle positioning member 100 in a manner that runs along the length direction of the clavicle positioning member 100, and the thread guide body 201 and the clavicle positioning member 100 are detachably connected.
[0047] In one embodiment of the present invention, the coracoid process crossing line and clavicle drilling positioning auxiliary device further includes a connecting component 400, the connecting component 400 comprising:
[0048] A connecting rod 401 is arranged vertically. A first clamping plate 402 is fixedly connected to the first end of the connecting rod 401. An adjusting rod 403 is threadedly connected to the first end of the connecting rod 401 along its length. A second clamping plate 404 is sleeved on the outside of the connecting rod 401. A clamping area is formed between the first clamping plate 402 and the second clamping plate 404. The clamping area matches the column 203. In use, the column 203 is placed in the clamping area, and the adjusting rod 403 is rotated. The adjusting rod 403 drives the second clamping plate 404 to move toward the first clamping plate 402, and the size of the clamping area decreases. The first clamping plate 402 and the second clamping plate 404 squeeze and position the wire guide assembly 200.
[0049] See Figure 1 and 3 The second end of the connecting rod 401 is provided with a slider 405. The clavicle positioning member 100 has a movable groove 102 along its length. The movable groove 102 matches the slider 405. The slider 405 is threadedly connected with a tension rod 406 that can be movably disposed toward the clavicle positioning member 100. In use, the connecting rod 401 can be pulled along the length of the clavicle positioning member 100. The second end of the connecting rod 401 slides in the movable groove 102 to move the wire guide assembly 200 to a suitable position. The tension rod 406 is further rotated, and the end of the tension rod 406 presses against the outer wall of the clavicle positioning member 100 to fix the relative position between the wire guide assembly 200 and the clavicle positioning member 100. Furthermore, one end of the movable groove 102 along its length is provided with a connecting disassembly groove, which is configured to allow the second end of the connecting rod 401 and the slider 405 to enter and exit, so as to facilitate the disassembly and assembly of the clavicle positioning member 100 and the connecting assembly 400.
[0050] The method of using the coracoid process crossing line and clavicle drilling positioning auxiliary device is as follows:
[0051] Assemble the various parts of the device. After skin incision, the suture assembly 200 passes under the coracoid process through the shoulder joint side b. After stabilization, the suture take-up assembly 300 is assembled with the suture assembly 200 on the sternal side a. Specifically, the first end of the connecting rod 401 in the connecting assembly 400 is connected to the suture assembly 200, and the second end of the connecting rod 401 in the connecting assembly 400 is connected to the clavicle positioning member 100. The suture take-up body 302 in the suture take-up assembly 300 is combined with the threading hole on the suture take-up body 201 in the suture assembly 200. At this time, the clamping member 301 in the suture take-up assembly 300 is located in the second port 2011b of the threading channel 2011.
[0052] The suture is fed downward from the first port 2011a of the threading channel 2011. In this embodiment, the suture is a suture, hereinafter referred to as PDS suture. When the PDS suture passes through the second port 2011b of the threading channel 2011, the infrared sensing mechanism 3014 located on the clamping member 301 detects the PDS suture passing through and alarms. The doctor presses the operating member 303, and the operating member 303 presses down the clamping member 301. The first clamping part 3011 and the second clamping part 3012 press the PDS suture tightly, further releasing the combination of the thread passing assembly 200 and the thread taking-up assembly 300, and completely passing the PDS suture through the coracoid process.
[0053] The embodiments described above are only used to illustrate the technical ideas and features of the present invention. Their purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly. The scope of patent application of the present invention should not be limited by these embodiments. That is, any equivalent changes or modifications made in accordance with the spirit disclosed in the present invention still fall within the patent scope of the present invention.
