[0002] In the field of surgery, surgical needles and sutures are critical consumables, and their safe use directly affects surgical outcomes and patient prognosis. Statistics show that approximately 1200-1500 cases of foreign bodies (such as needles, sutures, gauze, etc.) are left inside patients each year globally, potentially leading to serious consequences such as infection, tissue damage, and even death. Current techniques primarily rely on manual counting to avoid foreign body retention, depending on pre- and post-operative checks and verification of instruments and sutures by medical staff. However, this method is highly susceptible to human error and carries the risk of oversight.

[0003] Furthermore, the existing technical solutions have the following shortcomings: poor detection timeliness, inability to locate the surgical site in real time during postoperative imaging examinations, and the possibility of residual risks that can only be discovered after surgery; manual counting is inefficient and depends on the operator's experience. Therefore, this application proposes a new type of surgical needle and suture and scanning device to provide a new technical solution to solve the technical problems mentioned above.

[0036] As described in the background art, the following manual counting relies on medical staff to count and check instruments and sutures before and after the operation. However, it is greatly affected by human factors and there is a risk of omission. Postoperative imaging examinations cannot locate the instruments in real time during the operation, and the remaining risks can only be discovered after the operation.

[0044] The novel surgical needle and scanning device provided by this utility model, through the cooperative design of the surgical needle body and the scanning device body, allows the main scanning device to highlight the surgical needle body left in the patient's body on the display, thereby facilitating its retrieval and preventing it from being missed in the patient's body. This establishes a new paradigm for the prevention and control of foreign bodies during surgery, and is expected to significantly reduce medical risks and promote the intelligent upgrading of surgery.

[0045] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0046] Example 1:

[0047] Please refer to Figures 1-7 A novel surgical suture and scanning device, comprising:

[0048] The main body of the surgical needle, except for the tip, is coated with a reflective coating. Biocompatible reflective microspheres (such as titanium dioxide / silicon-based composite materials) are coated on the surface of the needle thread, enabling full material visualization through multispectral reflectivity. This coating exhibits high reflectivity (>90%) in the visible and near-infrared bands (400-1000nm), allowing it to be captured by scanning equipment without the need for an additional light source.

[0049] The scanning device includes a housing 1, a movable base 2 at the bottom of the housing 1, a vertically mounted lifting bracket 3 inside the housing 1 near the rear, extending from the bottom to the top of the housing 1, and a fixedly connected adjustable bracket 4 at the top of the lifting bracket 3. Two displays 5 are mounted on the adjustable bracket 4. A main unit 8 is located inside the housing 1, and both displays 5 are electrically connected to the main unit 8. Furthermore, the device also includes an image acquisition device, electrically connected to the main unit 8, used for image acquisition during surgery. The movable base 2 allows the scanning device to be moved, the housing 1 protects the main unit 8, the lifting bracket 3 adjusts the height of the adjustable bracket 4, and the adjustable bracket 4 allows for multi-directional adjustment of the orientation and angle of the two displays 5.

[0050] The equipment housing 1 has a frame assembly inside. The equipment housing 1 is fixed to the outside of the frame assembly. The frame assembly includes a fixed back frame 6 and a fixed front frame 7. The rear end of the fixed front frame 7 is fixedly connected to the fixed back frame 6. The main unit 8 is installed inside the fixed front frame 7. The lifting bracket 3 is located inside the fixed back frame 6.

[0051] Specifically, the lifting bracket 3 includes a bracket body 11, with guide wheel frames 12 and anti-slip components 13 respectively provided on the lower part of the bracket body 11. The guide wheel frames 12 are used to guide the vertical movement of the bracket body 11, and the anti-slip components 13 are used to limit the movement of the bracket body 11. The guide wheel frames 12 can guide and limit the lifting of the bracket body 11, effectively reducing the swaying phenomenon of the lifting bracket 3 during lifting. The anti-slip components 13 can adjust the lifting bracket 3 to achieve the limiting effect of the lifting bracket 3. The fixed back frame 6 includes a first upright 9 and a second upright 10, which are arranged horizontally parallel to each other. The bracket body 11 is located between the first upright 9 and the second upright 10, and the bracket body 11 is vertically slidably connected to the first upright 9 and the second upright 10 through the guide wheel frames 12.

[0052] Furthermore, a reinforcing frame 14 is fixedly connected to the lower part of the bracket body 11, and the guide wheel frame 12 is detachably and fixedly connected to the reinforcing frame 14. The reinforcing frame 14 can improve the stability of the bracket body 11. A bracket base 15 is fixedly connected to the upper end of the bracket body 11, and the bottom of the adjustable bracket 4 is detachably and fixedly connected to the bracket base 15. The bracket base 15 facilitates the installation and fixation of the adjustable bracket 4. A lifting handle 16 is fixedly connected to the front end and side of the upper end of the bracket body 11. The lifting handle 16 facilitates the lifting and lowering of the bracket 3.

[0053] Specifically, the guide wheel frame 12 includes a connecting frame 17, which is detachably fixed to the reinforcing frame 14 by multiple fixing screws 18. Both ends of the connecting frame 17 are connected to end seats 19. A first limiting guide wheel 20 and a second limiting guide wheel 21 are respectively provided on the side of the end seat 19 away from the connecting frame 17. The first limiting guide wheel 20 and the second limiting guide wheel 21 are arranged crosswise. Both the first limiting guide wheel 20 and the second limiting guide wheel 21 are rotatably connected to the end seat 19 via brackets. The first upright 9 and the second upright 1... Guide rails are vertically provided on the sides of the two sides that are close to each other. The first limiting guide wheel 20 and the second limiting guide wheel 21 are located inside the guide rails on the same side. The guide wheel frame 12 and the reinforcing frame 14 can be disassembled and fixed by fixing screws 18. The end seat 19 or the connecting frame 17 can be replaced by plugging the connecting frame 17 and the end seat 19. The guide wheel frame 12 can be moved and limited in the horizontal direction by the first limiting guide wheel 20 and the second limiting guide wheel 21, so that the lifting bracket 3 can only move up and down.

[0054] Specifically, the anti-slip component 13 includes a friction component 22 and a drive component 23. Two sets of friction components 22 are symmetrically arranged vertically. The drive component 23 is positioned between the two sets of friction components 22 and is used to drive the two sets of friction components 22 to move synchronously. The drive component 23 enables the two sets of friction components 22 to move synchronously, and through the contact between the friction components 22 and the inner walls of the first and second uprights 9 and 10, the resulting frictional force limits the movement of the bracket body 11.

[0055] Example 2:

[0056] The novel surgical needle and suture and scanning device provided in Example 1 have been further optimized, specifically, as follows: Figures 7-9 As shown, the drive assembly 23 includes a drive motor 24, which is fixedly connected to the bracket body 11 via a fixed bracket 25. A worm gear 28 is fixedly connected to the output end of the drive motor 24. A drive rod 26 is vertically arranged on one side of the worm gear 28. A worm wheel 27 is fixedly connected to the drive rod 26 near the worm gear 28. The worm wheel 27 is connected to the worm gear 28. A drive gear 34 for driving the friction assembly 22 is fixedly connected to the end of the drive rod 26.

[0057] Specifically, each friction assembly 22 includes a fixed plate 29, a fixed slide rail 30, an elastic frame 31, a first sliding seat 32, and a second sliding seat 33. Both ends of the fixed plate 29 are fixedly connected to the bracket body 11. Both sides of the fixed plate 29 are fixedly connected to the fixed slide rail 30. The upper end of the fixed slide rail 30 is provided with an elastic frame 31. The two ends of the elastic frame 31 are respectively fixedly connected to the first sliding seat 32 and the second sliding seat 33. The first sliding seat 32 and the second sliding seat 33 are slidably connected to the fixed slide rail 30 at the corresponding positions. The drive gear 34 at the end of the drive rod 26 is located between the two first sliding seats 32. The side of the two first sliding seats 32 near the drive gear 34 is fixedly connected to a fixed rack 35. The two first sliding seats 32 are meshed with the drive gear 34 at the end of the drive rod 26 through the fixed rack 35 on the side. When the drive gear 34 rotates, the two first sliding seats 32 move in opposite directions. The upper and lower ends of the drive rod 26 are fixedly connected to the fixed plate 29 at the same end through the stabilizing bracket 38, thereby reducing the shaking phenomenon of 26.

[0058] Furthermore, the lower ends of the first sliding seat 32 and the second sliding seat 33 are both provided with a third limiting guide wheel 37. The first sliding seat 32 and the second sliding seat 33 are slidably connected to the fixed slide rail 30 on the same side through the third limiting guide wheel 37. The end of the second sliding seat 33 away from the first sliding seat 32 is fixedly connected with a friction block 36.

[0059] Through the above structural design, the drive motor 24 drives the worm 28 to rotate. The worm 28 and worm wheel 27 work together to allow the drive rod 26 to drive the drive gear 34 to rotate synchronously when the worm 28 rotates. The first sliding seat 32 meshes with the drive gear 34 via a fixed rack 35. Thus, when the drive gear 34 rotates, the first sliding seat 32 can move one end of the elastic frame 31. When the first sliding seat 32 moves the elastic frame 31 towards the second sliding seat 33, the friction block 36 at the end of the second sliding seat 33... When the fixed back frame 6 is in contact, the first sliding seat 32 continuously drives one end of the elastic frame 31 to move, so that the friction between the friction block 36 on the other end of the elastic frame 31 and the fixed back frame 6 gradually increases, thereby achieving the effect of limiting the lifting of the bracket body 11. The structure of the worm gear 27 and the worm 28 can achieve a self-locking effect, thereby preventing the first sliding seat 32 from moving accidentally and effectively reducing the damage to the drive motor 24. When the height of the lifting bracket 3 needs to be adjusted, the drive motor 24 only needs to be flipped to reduce the friction between the drive rod 26 and the fixed back frame 6.
