Description

Technical Field

[0001] The invention relates to the technical field of wire passing devices, and in particular to a clavicle and coracoid bone tunnel alignment and a wire passing device. Background Art

[0002] Clavicle to coracoid tunnel alignment and wire passing device generally refers to a fixation or reconstruction technique used in orthopedic surgery, especially when dealing with acromioclavicular joint injuries or certain types of clavicle fractures. Clavicle to coracoid tunnel: In the shoulder, the clavicle and coracoid are adjacent anatomical structures. In certain surgeries, the surgeon drills tunnels in the clavicle and coracoid that are used to pass specific fixation devices or wires. During surgery, it is critical to ensure that the tunnels on the clavicle and coracoid are properly aligned. This alignment ensures that the fixation device or wire can be passed in the correct anatomical location to achieve a stable fixation or reconstruction.

[0003] The clavicle and coracoid bone channel alignment and wire passing device generally includes a coracoid positioning hook, a guide sleeve, and a guide needle sleeve, wherein the guide needle sleeve contacts the clavicle, and the coracoid positioning hook contacts the coracoid. The clavicle is located in front of the shoulder and is relatively shallow, so when making an incision, the surface of the clavicle can be directly seen through the skin and superficial tissue. However, the coracoid is located at the front edge of the scapula, is located deeper, and is covered by muscles and other soft tissues. Therefore, the incision at the coracoid position usually cannot directly see the coracoid. During surgery, the end of the coracoid positioning hook with the positioning hook, that is, the surgical operation end, needs to be inserted into the body through the incision, but there are many important nerves in the shoulder area, such as branches of the brachial plexus. When the positioning hook is inserted into the body, the hook will directly contact the body during the insertion process, and the positioning hook cannot be retracted, so a larger incision is required to insert the positioning hook into the body, and when placing the positioning hook, it is inconvenient to observe, and the hook of the positioning hook is easy to accidentally touch or compress these nerves, which may cause loss of sensation, pain or muscle weakness. The muscles of the shoulder, such as the pectoralis major, deltoid, and subscapularis, may be injured by the insertion of the positioning hook. Summary of the invention

DETAILED DESCRIPTION

[0037] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0038] Example

[0039] like Figure 1-4 and Fig.10As shown, the clavicle and coracoid bone channel alignment and line passing device proposed by the present invention comprises a coracoid positioning hook 1, a guide sleeve 2 and a guide needle sleeve 3 detachably mounted on the guide sleeve 2, a clamping pin 301 is fixedly mounted on the guide needle sleeve 3, and the guide needle sleeve 3 can be clamped and positioned with the clavicle through the clamping pin 301. The coracoid positioning hook 1 comprises a surgical operation end 101 and a handle end 102. During surgery, the surgical operation end 101 needs to be inserted into the patient's body through a surgical incision, and the surgical operation end 101 is pressed against the patient's coracoid. The handle end 102 is slidably connected to the guide sleeve 2, and a clamping assembly for fixing the handle end 102 is installed on the guide sleeve 2. The clamping assembly comprises a placement groove 10 arranged in the guide sleeve 2, a pressing block 1001 is slidably installed in the placement groove 10, and a transmission rod 1002 is rotatably installed on the pressing block 1001. The transmission rod 1002 penetrates the guide sleeve 2 and extends to the outside of the guide sleeve 2, and the transmission rod 1002 is threadedly connected to the guide sleeve 2. The guide sleeve 2 can slide along the handle end 102 and can be disassembled. After the position of the guide sleeve 2 is adjusted, the transmission rod 1002 is rotated to drive the pressure block 1001 to move closer to the handle end 102, so that the pressure block 1001 presses and fixes the handle end 102, which can ensure the stability of positioning during the operation.

[0040] A first support seat 201 is fixedly installed on the guide sleeve 2, and a second support seat 202 is rotatably installed on the first support seat 201. The guide needle sleeve 3 is slidably installed between the first support seat 201 and the second support seat 202. A latch 203 is detachably installed on the first support seat 201 and the second support seat 202. The latch 203 is connected to the first support seat 201 and the second support seat 202 through a threaded connection. By removing the latch 203, the second support seat 202 can be rotated on the first support seat 201, and the first support seat 201 and the second support seat 202 can be separated, which makes it easy to remove the guide needle sleeve 3 from the first support seat 201 and the second support seat 202.

[0041] Among them, a locking mechanism for limiting the position of the guide needle sleeve 3 is installed on the second support seat 202. The locking mechanism includes a plurality of limiting grooves 4 arranged on the guide needle sleeve 3, and a mounting groove 401 is arranged on the second support seat 202. A locking block 402 is rotatably installed in the mounting groove 401, and the locking block is fitted with one side of the mounting groove 401. A spring 403 is fixedly installed on the locking block 402, and the other end of the spring 403 is fixedly connected with the mounting groove 401. When the guide needle sleeve 3 moves downward along the first support seat 201 and the second support seat 202, the guide needle sleeve 3 will gradually approach the clavicle. In this process, the downwardly moving guide needle sleeve 3 will drive the limiting groove 4 to move downward. At this time, the locking block 402 can rotate downward under the action of the limiting groove 4 and compress the spring 403. When the limiting groove 4 is separated from the locking block 402, the locking block 402 will be reset under the action of the spring 403, so that the locking block 402 enters the next limiting groove 4. The guide needle sleeve 3 can move downward freely to facilitate the contact between the guide needle sleeve 3 and the clavicle. After the position of the guide needle sleeve 3 is adjusted, the guide needle sleeve 3 can be prevented from moving upward under the action of the locking block 402. This is because when the guide needle sleeve 3 moves upward, the locking block 402 will be driven to rotate upward through the limiting groove 4, and the upper side of the locking block 402 abuts against the upper side of the limiting groove 4, so that the locking block 402 does not have space to rotate upward, and the locking block 402 cannot be rotated upward, so that the guide needle sleeve 3 cannot be moved upward, and thus the guide needle sleeve 3 can be effectively prevented from loosening.

[0042] like Figure 1-3 and Figure 5-7 as well as Figure 11-15 As shown, it also includes two retractable positioning hooks 502 installed on the surgical operation end 101. The retractable positioning hooks 502 are hollow structures and are made of flexible materials without elasticity. The retractable positioning hooks 502 can be retracted and folded in the up and down directions, which is beneficial to reduce the volume of the retractable positioning hooks 502 when not in use. When the retractable positioning hooks are placed in the coracoid process of the patient, the retractable positioning hooks 502 can be retracted to reduce the size of the incision, and the area of ​​contact between the retractable positioning hooks 502 and the nerves and muscles at the shoulder can be effectively reduced, thereby effectively preventing the retractable positioning hooks 502 from causing damage to the muscles and nerves at the shoulder. The surgical operation end 101 is equipped with a retractable control component for controlling the retractable positioning hooks 502 to retract and an angle adjustment component for adjusting the angle between the two retractable positioning hooks 502. Through the retraction control component, after the retraction positioning hook 502 is moved below the coracoid process, the retraction positioning hook can be raised so that the retraction positioning hook 502 contacts the coracoid process, and the angle between the two retraction positioning hooks 502 can be adjusted through the angle adjustment component to facilitate better contact between the retraction positioning hook 502 and the coracoid process to ensure the stability of fixation.

[0043] Furthermore, a cavity 5 is provided in the surgical operation end 101, a connecting cavity 503 is provided in the middle of the coracoid positioning hook 1, the connecting cavity 503 is communicated with the cavity 5, two elastic connecting pieces 501 are fixedly installed on the surgical operation end 101, the elastic connecting pieces 501 are communicated with the cavity 5, the retractable positioning hook 502 is fixedly connected with the elastic connecting piece 501, and the retractable positioning hook 502 penetrates the elastic connecting piece 501 and extends into the cavity 5. The provision of the elastic connecting piece 501 can block the gap between the retractable positioning hook 502 and the cavity 5, and can enable the retractable positioning hook 502 to have a certain range of motion on the surgical operation end 101.

[0044] Among them, the contraction control component includes a box body 6 fixedly installed on the coracoid positioning hook 1, and a pressure plate 601 sliding in the box body 6. A driving rod 602 is rotatably installed on the pressure plate 601. The driving rod 602 penetrates the box body 6 and extends to the outside of the box body 6. The driving rod 602 is threadedly connected to the box body 6. A delivery pipe 603 is fixedly installed at the bottom of the box body 6. Two connecting pipes 604 are provided at the bottom of the contraction positioning hook 502. The connecting pipe 604 is connected to the inside of the contraction positioning hook 502. The delivery pipe 603 is fixedly connected and connected to the connecting pipe 604. The box body 6 is provided with a filling liquid below the pressure plate 601. When the retracted positioning hook 502 needs to be expanded, the driving rod 602 needs to be rotated. The rotating driving rod 602 will drive the pressure plate 601 to move downward, and the downward pressure plate 601 will squeeze the filling liquid, so that the filling liquid inside the box body 6 can be moved to the inside of the retracted positioning hook 502 through the delivery pipe 603 and the connecting pipe 604, and the filling liquid can fill the space inside the retracted positioning hook 502. Under the pressure of the filling liquid, the retracted positioning hook 502 will gradually expand and the retracted positioning hook 502 can be gradually raised. After the space inside the retracted positioning hook 502 is filled, since the retracted positioning hook 502 does not have elastic force, the retracted positioning hook in this state can be in a rigid state, thereby enabling the retracted positioning hook 502 to maintain an effective positioning state.

[0045] The contraction control component also includes a traction rope 605 fixedly installed on the top of the contraction positioning hook 502, a first wire reel 606 is rotatably installed on the coracoid positioning hook 1, a first handle 607 is fixedly installed on the first wire reel 606, and the traction rope 605 is fixedly connected to the first wire reel 606 through the connecting cavity 503. After the drilling is completed, when the retractable positioning hook 502 needs to be removed from the patient's body, the first handle 607 is rotated to drive the first take-up reel 606 to rotate, so that the first take-up reel 606 can wrap around the traction rope 605, and then the top of the retractable positioning hook 502 can be stretched through the traction rope 605, so that the top of the retractable positioning hook 502 moves downward. At this time, the driving rod 602 is rotated to drive the pressure plate 601 to rise, so that there is enough space in the box 6 to hold the filling liquid that flows back into the inside of the retractable positioning hook 502. The retractable positioning hook 502 can be retracted under the action of the traction rope 605, so that when the retractable positioning hook 502 is taken out, the retractable positioning hook 502 is prevented from scratching the muscles and nerves, which effectively improves the safety during the operation.

[0046] Furthermore, the angle adjustment assembly includes a driving plate 7 fixedly mounted on the retracted positioning hook 502, support rods 701 are fixedly mounted on both sides of the driving plate 7, the support rods 701 are rotatably connected to the inner wall of the cavity 5, a telescopic rod 702 is fixedly mounted in the cavity 5, a lifting plate 703 is fixedly mounted on the other end of the telescopic rod 702, a slide groove 704 is provided on the lifting plate 703, two connecting heads 705 are slidably mounted in the slide groove 704, a first connecting rod 706 is rotatably mounted on the connecting head 705, the first connecting rod 706 corresponds to the driving plate 7 one by one and is fixedly connected, a plurality of sliding rods 707 are fixedly mounted in the cavity 5, a pull plate 708 is slidably mounted on the sliding rod 707, elastic connecting ropes 709 are fixedly mounted on both ends of the pull plate 708, the other end of the elastic connecting rope 709 is fixedly connected to the inner wall of the cavity 5, a second connecting rod 710 is rotatably mounted in the pull plate 708, and the other end of the second connecting rod 710 is rotatably connected to the lifting plate 703. When the pull plate 708 slides along the sliding rod 707 toward the end away from the elastic connecting rope 709, the elastic connecting rope 709 will be stretched. At this time, the elastic connecting rope 709 will apply tension to the pull plate 708. When the pull plate 708 is not affected by external force, the pull plate 708 will be driven to slide toward the side close to the elastic connecting rope 709 under the tension of the elastic connecting rope 709. When the pull plate 708 slides, it will drive the second connecting rod 710 to rotate. The rotating second connecting rod 710 will apply thrust or tension to the lifting plate 703, which can drive the lifting plate 703 to move up and down along the axial direction of the telescopic rod 702. When the lifting plate 703 is lifted When the lifting plate 703 is lifted up, the connecting heads 705 on both sides are driven to slide along the slide grooves 704, and the connecting heads 705 are lifted and lowered along with the lifting plate 703. At this time, the connecting heads 705 will drive the first connecting rod 706 to rotate, and the rotating first connecting rod 706 will drive the support rod 701 to rotate, thereby driving the driving plate 7 fixedly connected to the support rod 701 to rotate, thereby driving the retractable positioning hook 502 installed on the driving plate 7 to rotate, so that the angles of the two retractable positioning hooks 502 can be properly adjusted, so that the retractable positioning hook 502 can be more closely fitted to the coracoid process, which is beneficial to improving the stability of the retractable positioning hook 502 during use.

[0047] Among them, when using the retractable positioning hook 502 for positioning, the two retractable positioning hooks 502 are generally outward-expanding in order to adapt to the structure of the coracoid process, which results in the two outward-expanding retractable positioning hooks 502 requiring a larger incision to enter the patient's body. The two retractable positioning hooks 502 can be retracted through the angle adjustment component, thereby reducing the lateral area of ​​the retractable positioning hook 502 and further reducing the length of the incision.

[0048] The angle adjustment assembly also includes a second take-up reel 711 rotatably mounted on the coracoid positioning hook 1, a second handle 712 fixedly mounted on the second take-up reel 711, a pull rope 713 fixedly mounted on the second take-up reel 711, and the pull rope 713 fixedly connected to the pull plate 708 through the connecting cavity 503. The second take-up reel 711 is rotated by rotating the second handle 712, and the rotating second take-up reel 711 pulls the pull rope 713, thereby driving the pull plate 708 to move, thereby adjusting the angle between the two contraction positioning hooks 502.

[0049] like Figure 8 As shown, the first wire take-up reel 606 and the second wire take-up reel 711 are both installed with an anti-loosening mechanism, which includes a plurality of slots 8 provided on the first wire take-up reel 606 and the second wire take-up reel 711, a clamping strip 801 rotatably installed on the coracoid process positioning hook 1, and a rebound block 802 fixedly installed on the coracoid process positioning hook 1, a spring 803 is fixedly installed between the rebound block 802 and the clamping strip 801, an anti-loosening block 804 is rotatably installed on the coracoid process positioning hook 1, and the anti-loosening block 804 abuts against one side of the clamping strip 801. When the first wire take-up reel 606 or the second wire take-up reel 711 rotates forwardly, it will drive the clamping strip 801 to rotate, and the rotating clamping strip 801 will gradually disengage from the inside of the clamping slot 8. At this time, the clamping strip 801 will not be able to limit the first wire take-up reel 606 and the second wire take-up reel 711, so that the first wire take-up reel 606 and the second wire take-up reel 711 can rotate freely forward, and the angle and contraction degree of the contraction positioning hook 502 can be adjusted. When the adjustment is completed, the first wire take-up reel 606 and the second wire take-up reel 711 will be limited under the action of the clamping strip 801 to prevent the first wire take-up reel 606 and the second wire take-up reel 711 from reversing, thereby preventing the angle between the two contraction positioning hooks 502 from changing or the contraction amount of the contraction positioning hook 502 from changing due to accidental touch during the operation, and ensuring that the contraction positioning hook 502 remains stable during the operation. When the first wire take-up reel 606 and the second wire take-up reel 711 need to rotate in the opposite direction, the anti-loosening block 804 needs to be rotated so that the anti-loosening block 804 does not rest against the clamping strip 801. At this time, the anti-loosening block 804 will not limit the clamping strip 801, so that the first wire take-up reel 606 and the second wire take-up reel 711 can rotate in the opposite direction.

[0050] like Fig. 9As shown, a reinforcement is installed in the retractable positioning hook 502, and the reinforcement includes a plurality of reinforcement plates 9 rotatably installed in the retractable positioning hook 502, and two adjacent reinforcement plates 9 are rotatably connected, and a reinforcement rod 901 is fixedly installed on the driving plate 7, and a multi-stage telescopic rod 902 is fixedly installed on the reinforcement rod 901, and the multi-stage telescopic rod 902 penetrates the reinforcement plate 9 and is fixedly connected to the top of the retractable positioning hook 502. Through the arrangement of the reinforcement plate 9 and the multi-stage telescopic rod 902, it can be ensured that the retractable positioning hook 502 does not tilt when subjected to a lateral force, and the retractable positioning hook 502 can be ensured to be in a stable contact state with the coracoid process.

[0051] Working principle: After the retractable positioning hook 502 is moved to below the coracoid process, the driving rod 602 is rotated, and the rotating driving rod 602 will drive the pressure plate 601 to move downward, and the downwardly moved pressure plate 601 moves the filling liquid inside the box body 6 to the inside of the retractable positioning hook 502 through the delivery tube 603 and the connecting tube 604. Under the pressure of the filling liquid, the retractable positioning hook 502 will gradually expand and the retractable positioning hook 502 can be gradually raised. After the space inside the retractable positioning hook 502 is filled, since the retractable positioning hook 502 does not have elastic force, the retractable positioning hook in this state can be in a rigid state, thereby enabling the retractable positioning hook 502 to maintain an effective positioning state.

[0052] By rotating the second handle 712, the second take-up reel 711 is driven to rotate, and the pull plate 708 is driven to slide toward the side close to the elastic connecting rope 709. When the pull plate 708 slides, it will drive the second connecting rod 710 to rotate. The rotating second connecting rod 710 will drive the driving plate 7 fixedly connected to the support rod 701 to rotate, thereby driving the retraction positioning hook 502 installed on the driving plate 7 to rotate, so that the angles of the two retraction positioning hooks 502 can be properly adjusted, and the retraction positioning hook 502 can be made to fit more closely to the coracoid process, which is beneficial to improving the stability of the retraction positioning hook 502 during use.

[0053] After the drilling is completed, the first take-up coil 606 is rotated by rotating the first handle 607, and the top of the retractable positioning hook 502 is stretched by the traction rope 605, so that the top of the retractable positioning hook 502 moves downward, so that the retractable positioning hook 502 can be retracted under the action of the traction rope 605, so that when the retractable positioning hook 502 is taken out, it is prevented from scratching the muscles and nerves by the retractable positioning hook 502, which effectively improves the safety during the operation. And by rotating the second handle 712, the two retractable positioning hooks 502 are brought closer to each other, reducing the contact area between the surgical operation end and the patient's muscles, and improving the safety of use.

[0054] The above specific embodiments are only several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
