Description

Technical Field

[0001] This utility model relates to the field of retractor devices, specifically to a retractor for anterior cervical spine surgery. Background Technology

[0002] In anterior cervical spine surgery, surgeons need to retract soft tissues such as blood vessels, trachea, and esophagus to facilitate surgical procedures. The design and development of specialized retractors for anterior cervical spine surgery stems from the specific need for soft tissue retraction in cervical spine surgery. In traditional cervical spine surgery, surgeons often face the challenge of effectively retracting key soft tissues such as blood vessels, trachea, and esophagus to clearly expose the surgical area and ensure the accuracy and safety of the surgical procedure. However, traditional retraction tools, such as thyroid retractors, often have drawbacks such as poor fit, easy slippage, and unsatisfactory exposure. This not only increases surgical time and bleeding but may also lead to damage to surrounding tissues, affecting the surgical outcome.

[0003] Currently, to facilitate tissue retraction, specialized retractors are typically used. However, commercially available retractors generally lack corresponding fixing parts at their ends, preventing them from being secured to external supports or hospital beds. This necessitates manual handling by the staff, impacting ease of use and causing inconvenience. Therefore, we propose a specialized retractor for anterior cervical spine surgery.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0024] Please see Figures 1-3 This utility model provides a technical solution: a special pull hook for anterior cervical spine surgery, including a vertical rod 1, a first pull hook 10 fixedly installed at the bottom end of the vertical rod 1, a traction rope 16 fixedly installed at the top end of the vertical rod 1, and an outer hook 17 fixedly installed at the end of the traction rope 16. The outer hook 17 is used to suspend on an external object for suspension operation.

[0025] Specifically, the pull rope 16 is equipped with a pull rope tightening assembly 2, which includes two symmetrical support discs 20 on the left and right. A handle 21 is fixedly installed between the two support discs 20, and a rotating shaft 22 is rotatably connected between the two support discs 20. One end of the rotating shaft 22 extends out of the support disc 20 and is fixedly installed with a rotating handle 25. A stud 26 is threaded onto the rotating handle 25, and a knob 27 is fixedly installed at the end of the stud 26. The middle part of the pull rope 16 is located on the rotating shaft 22. Specifically, the middle part of the pull rope 16 is fixed to the rotating shaft 22, and both ends of the pull rope 16 are wound around the rotating shaft 22 in the same direction. This ensures that when the rotating shaft 22 rotates clockwise or counterclockwise during use, the pull rope 16 can be wound or unwound. After the pull rope 16 is tightened to a suitable degree, the stud 26 is tightened. At this time, the stud 26 abuts against the support disc 20, which can prevent the rotating shaft 22 from rotating freely.

[0026] In this embodiment, two symmetrical limiting discs 23 are fixedly installed on the surrounding shaft 22. The limiting discs 23 are attached to the inner side of the support disc 20 and are rotatably connected to the support disc 20. The limiting discs 23 can prevent the surrounding shaft 22 from falling off the support disc 20.

[0027] Specifically, an anti-slip layer 24 is provided on the outer surface of the support plate 20 near the stud 26. The anti-slip layer 24 is used to increase friction. The end of the stud 26 abuts against the anti-slip layer 24 to achieve the effect of anti-slip protection.

[0028] Furthermore, multiple steel wire ropes 12 are provided on the vertical rod 1, and a protruding post 13 is fixedly installed at the end of the steel wire rope 12. A second hook 14 is fixedly installed at the end of the protruding post 13, so that the second hook 14 can be used to perform further pulling operations.

[0029] In addition, fixing rings 11 are fixedly installed at different positions on the vertical rod 1, and the ends of the wire ropes 12 are fixedly installed on the corresponding fixing rings 11. The lengths of the multiple wire ropes 12 are different, so that the corresponding second hooks 14 can be selected for pulling operation as needed.

[0030] It is worth noting that the ends and sides of the first hook 10 and the second hook 14 are provided with arc-shaped smooth edges 15. The arc-shaped smooth edges 15 are used to reduce friction and make it less likely to damage the tissue during the traction operation.

[0031] It is worth noting that a groove 171 is provided on the inner side of the outer hook 17, and the cross section of the groove 171 is larger than half a circle; the length of the pull rope 16 is greater than 50cm, and the vertical rod 1 is a rigid rod structure.

[0032] When using the cervical anterior cervical spine surgery retractor of this utility model, the first retractor 10 is used to retract the patient's blood vessels, trachea, esophagus and other soft tissues along the incision of the surgical site. Depending on the size of the retracted area, the second retractor 14 is selected to continue the retraction operation on other parts. Then, the outer hook 17 is suspended at the corresponding frame part on the outside. Then, the rotating shaft 22 is rotated to wind up the retraction rope 16, so that the first retractor 10 and the second retractor 14 can retract the soft tissue to a certain extent. After the retraction rope 16 is tightened, the stud 26 is tightened. At this time, the stud 26 is used to abut against the anti-slip layer 24 to prevent the rotating shaft 22 from loosening and rotating freely.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
