Abstract
Description
Technical Field
[0001] This utility model relates to the field of Achilles tendon suturing technology, and more specifically to an Achilles tendon suturing puncture guidance structure based on laser positioning. Background Technology
[0002] The Achilles tendon, the thickest tendon in the human body, plays a crucial role in transmitting mechanical energy between the gastrocnemius-soleus muscle complex and the calcaneus. During dorsiflexion movements of the foot and ankle, such as walking, running, and jumping, it bears tensile forces up to 12 times the body weight, and its integrity directly affects lower limb motor function. Clinical statistics show that approximately 18 Achilles tendon ruptures occur annually per 100,000 people worldwide, with 75% occurring in active individuals aged 30-50. Acute ruptures are often caused by sudden exertion during exercise (such as jumping in basketball or accelerating in sprints), while chronic injuries are common in patients with tendon degeneration due to conditions such as diabetes and rheumatoid arthritis. Achilles tendon repair emphasizes the three principles of "anatomical reconstruction, mechanical stability, and early rehabilitation," with suture devices playing a key role in this process. Integrated puncture guidance systems can achieve deep suturing through a 3-5mm incision, reducing soft tissue dissection by 70% compared to open surgery and significantly lowering the rate of sural nerve injury.
[0003] As shown in the prior art published in CN203815515U, although this prior art uses an oval forceps in conjunction with an Achilles tendon minimally invasive suturing aiming device, the aiming device can efficiently and accurately guide the dura mater needle percutaneously through the oval foramen of the oval forceps, achieving minimally invasive Achilles tendon surgery, simplifying the difficulty of the surgical procedure, and reducing nerve damage. However, in this prior art, the puncture path of the suture needle is not limited or guided when it punctures into the Achilles tendon, which can easily lead to the suture head deviating and damaging tissue, thereby affecting suturing efficiency and puncture accuracy. Utility Model Content
[0004] To overcome the aforementioned deficiencies in the prior art, this utility model provides a laser-guided Achilles tendon suture puncture structure. A miniature laser illuminates the movement point of the puncture tube, which then extends through another puncture hole on the oval forceps. This allows for direct external visualization of the puncture point, ensuring accurate penetration of the Achilles tendon and preventing misalignment that could damage other tissues at the Achilles tendon. This reduces damage and improves puncture efficiency, thus solving the problems described in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a laser-guided Achilles tendon suture puncture structure, including a puncture tube 1, a miniature laser 3 is provided at the front end of the puncture tube 1, and the miniature laser 3 is detachably connected to the puncture tube 1.
[0006] In a preferred embodiment, a mounting post is provided inside one end of the puncture tube, and the mounting post is detachably connected to the puncture tube. A miniature laser is installed on the side of the mounting post away from the puncture tube.
[0007] In a preferred embodiment, an assembly ring is fixedly connected to the side of the mounting post away from the micro laser, and the assembly ring has an external thread. The puncture tube has an internal thread on the side corresponding to the assembly ring. The assembly ring is threadedly connected to the puncture tube. Through the threaded connection between the assembly ring and the puncture tube, the micro laser can be easily disassembled for inspection, maintenance or disinfection, while also facilitating the passage of the suture 15 through the puncture tube.
[0008] In a preferred embodiment, two operating holes are provided on the outer side of the end of the puncture tube near the mounting post, and the two operating holes are symmetrically distributed about the central axis of the puncture tube. By providing two spaced operating holes on the outside of the puncture tube, medical personnel can easily rotate the mounting post through the operating holes, thereby facilitating the separation of the rotating assembly ring from the puncture tube and achieving the effect of assembling and disassembling the miniature laser.
[0009] In a preferred embodiment, the outer wall of the mounting column is evenly distributed with multiple strip grooves.
[0010] In a preferred embodiment, the rear end of the mounting post is provided with a binding head for securing the suture thread.
[0011] In a preferred embodiment, the puncture tube includes a puncture head and a puncture tail, and a support column for mounting a micro laser is provided inside the puncture head, and the puncture head 10 is fixedly connected to the support column 12.
[0012] The support column is fixedly connected to a support ring at one end near the puncture tail. The support ring extends into the interior of the puncture tail and is threadedly connected to the puncture tail.
[0013] In a preferred embodiment, the rear end of the support column is provided with a binding head for binding sutures.
[0014] The technical effects and advantages of this utility model are as follows:
[0015] 1. The movement point of the puncture tube is illuminated by a miniature laser and can be seen through another puncture hole on the oval forceps. This allows for a direct visual understanding of the movement point of the positioning puncture device from the outside, ensuring that the positioning puncture device can accurately pass through the Achilles tendon, avoiding misalignment of the positioning puncture device and damage to other tissues at the Achilles tendon, reducing damage and improving puncture efficiency.
[0016] 2. The assembly ring is connected to the puncture tube by a thread, which makes it easy to move the mounting post through the operating hole. The mounting post then drives the assembly ring to separate from the internal thread, making it easy to remove the miniature laser for inspection and maintenance. At the same time, it makes it easy for the suture 15 to pass through the puncture tube.
[0017] 3. The support ring on the support column is connected to the puncture tail thread, making the puncture head and puncture tail detachable. The puncture head can be rotated directly from the outside, which improves the convenience of disassembling the micro laser and also makes it easier to remove the suture, thus improving the convenience of puncture suture.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Example 1: To improve the efficiency of Achilles tendon suturing, it is necessary to improve the accuracy of the puncture cannula 1 in puncturing the Achilles tendon, such as... Figure 1-4As shown, a mounting post 2 is provided inside one end of the puncture tube 1, and the mounting post 2 is detachably connected to the puncture tube 1. A miniature laser 3 (which can be a vertical cavity surface emission laser Lumentum HVSIL 940nm) is installed on the side of the mounting post 2 away from the puncture tube 1.
[0027] Refer to the instruction manual appendix Figure 1-6 The auxiliary component used for suturing the Achilles tendon is an oval forceps 8 for clamping the Achilles tendon. Both ends of the oval forceps 8 are machined with puncture holes 9. The puncture holes 9 are positioned laterally to the puncture tube 1. Medical staff can use one hand to operate the oval forceps 8 to clamp the patient's Achilles tendon, thereby positioning the puncture holes 9 on both sides of the Achilles tendon and making the puncture holes 9 parallel to the position of the Achilles tendon. The position of the Achilles tendon can be initially located through the puncture holes 9, which facilitates subsequent puncture and suturing.
[0028] After the patient's Achilles tendon is clamped, before the medical staff operate the puncture tube 1, the medical staff tie the suture to the ligature head 14 so that the suture can be inserted into the patient's Achilles tendon along with the puncture tube 1. Afterwards, medical staff insert the puncture tube 1 into the Achilles tendon through one of the puncture holes 9 on the oval forceps 8. Because the miniature laser 3 is installed at the end of the puncture tube 1, the miniature laser 3 can illuminate the movement path of the puncture tube 1. Moreover, the near-infrared light of the miniature laser 3 has a low absorption coefficient in the skin, and is mainly scattered rather than being absorbed by hemoglobin or water. This allows it to penetrate deeper tissues, including the skin at the Achilles tendon, and exit through another puncture hole 9 on the oval forceps 8. This allows medical staff to visually understand the movement point of the puncture tube 1 from the outside, ensuring that the puncture tube 1 can accurately pass through the appropriate soft tissue at the Achilles tendon and then exit through another puncture hole 9. This avoids the puncture tube 1 from becoming crooked and damaging other tissues at the Achilles tendon, reducing damage and improving puncture efficiency.
[0029] After the puncture, the miniature laser 3 needs to be removed to facilitate the placement of the suture inside the puncture tube 1, such as... Figure 2-4As shown, the mounting post 2 is fixedly connected to the side away from the miniature laser 3 with an assembly ring 4, and the assembly ring 4 has an external thread 5 machined on its exterior. The puncture tube 1 has an internal thread 6 machined on the side corresponding to the assembly ring 4. The assembly ring 4 is threadedly connected to the puncture tube 1. Because the assembly ring 4 is connected to the internal thread 6 on the puncture tube 1 through the external thread 5, and because the puncture tube 1 has two operating holes 7 on its exterior near the mounting post 2, and the two operating holes 7 are symmetrically distributed about the central axis of the puncture tube 1, when medical staff rotate the mounting post 2 through the operating holes 7 (the mounting post 2 can be rotated using tweezers or other pointed tools), the mounting post 2 can also drive the assembly ring 4 to rotate, causing the assembly ring 4 to separate and misalign with the internal thread 6, thereby achieving the effect of removing the miniature laser 3. At the same time, the mounting post 2 also brings the suture out of the puncture tube 1, so that the suture can be accurately inserted into the Achilles tendon, thereby achieving the insertion of the suture. After the suture is inserted, the puncture tube 1 is removed, and the suture can be manipulated to suture the patient's Achilles tendon.
[0030] The assembly ring 4 is fixed together with the mounting post 2. The outer surface of the assembly ring 4 is machined with external threads, and then the external threads on the assembly ring 4 are connected to the internal threads on the piercing tube 1, thereby achieving the effect of convenient assembly and disassembly of the mounting post 2 and the miniature laser 3.
[0031] Multiple strip grooves are evenly distributed on the outer wall of the mounting column 2; this facilitates the movement of the mounting column 2.
[0032] Operating holes 7 can be symmetrically distributed on both sides of the puncture tube 1.
[0033] Both the miniature laser 3 and the assembly ring 4 are connected and fixed to the mounting post 2, and the mounting post 2 is connected to the puncture tube 1 through the external thread on the assembly ring 4. Thus, when the assembly ring 4 is disassembled and separated from the puncture tube 1, the mounting post 2 and the miniature laser 3 on it are also removed together, thereby realizing the disassembly of the miniature laser 3.
[0034] Example 2, see attached instruction manual Figure 5 and 6 The puncture tube 1 includes a puncture head 10 and a puncture tail 11. The puncture head 10 is provided with a support column 12 for mounting the micro laser 3. The puncture head 10 is fixedly connected to the support column 12.
[0035] A support ring 13 is fixedly connected to one end of the support column 12 near the puncture tail 11. The support ring 13 extends into the interior of the puncture tail 11 and is threadedly connected to the puncture tail 11. Both the mounting column 2 and the support column 12 are provided with binding heads 14 for binding sutures at their rear ends.
[0036] Medical staff tie the suture to the binding head 14 (the binding head 14 can also be hook-shaped or loop-shaped) on the support column 12, so that the suture can be inserted into the patient's Achilles tendon along with the puncture piece. After that, after the patient's Achilles tendon is fixed by the oval forceps 8, the medical staff insert the puncture head 10 and puncture tail 11 into the Achilles tendon through the puncture hole 9 on the oval forceps 8, and use the miniature laser 3 to irradiate the movement path of the puncture head 10. At the same time, the miniature laser 3 can penetrate the skin at the Achilles tendon and can also be exposed through another puncture hole 9 on the oval forceps 8. This allows the medical staff to visually understand the movement point of the puncture head 10 from the outside, thereby ensuring that the puncture head 10 can accurately pass through the soft tissue at the appropriate position of the Achilles tendon.
[0037] After penetrating the patient's Achilles tendon, the puncture head 10 and puncture tail 11 are connected by a threaded support ring 13 on the support column 12. The puncture head 10 is fixedly connected to the support column 12. Therefore, when the puncture head 10 is rotated, it also drives the support ring 13 on the support column 12 to rotate, separating the support ring 13 from the puncture tail 11, thus facilitating the disassembly of the miniature laser. Simultaneously, the suture 15 tied to the support column 12 is exposed, allowing the suture 15 to be inserted along with the puncture tube 1, avoiding the waste of valuable surgical time by having to pass the suture 15 through the puncture tube 1 after the puncture is complete.
[0038] Guided by the miniature laser 3, the Achilles tendon can be precisely penetrated. Finally, the suture 15 tied to the support post 12 is cut, and the puncture tail 11 is removed. This facilitates medical personnel in manipulating the suture 15 to perform medical procedures on the Achilles tendon. The overall structure is simple and convenient to operate, effectively improving puncture accuracy and suturing convenience.
[0039] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
