[0033] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0034] Example 1: As shown in the attached Figure 1 To the attached Figure 5 As shown: The present invention provides a thyroid surgery retractor, including a structural assembly 100, including a structural member 101, an adjusting member 102 arranged outside the structural member 101, a retracting member 103 slidably arranged outside the adjusting member 102, and a lifting member 104 arranged on one side of the structural member 101;

[0035] Structural element 101, serving as the basic support structure for the retractor, primarily comprises two fixed rods 101a, a fixed plate 101b fixedly mounted to one end of the fixed rods, and a lifting platform 101c fixedly mounted to the other end of the fixed rods. Fixed rods 101a possess sufficient strength and stability to support the weight of the retractor and the operating forces during surgery. Fixed plate 101b secures the retractor to the operating table or other supporting structure, ensuring stability during surgery. Lifting platform 101c, in conjunction with lifting element 104, enables precise adjustment of the retractor's height.

[0036] The adjusting member 102 includes an adjusting column 102a slidably disposed outside the fixed rod 101a. Two adjusting columns 102a are provided and are symmetrically distributed about the midline of the adjusting rod. The adjusting columns 102a can slide outside the fixed rod 101a, thereby driving the retractor 103 to move and retract the surgical site.

[0037] The retractor 103 includes a collar 103a slidably disposed on the outside of the adjustment column 102a and a traction hook 103b rotatably mounted on the lower end of the collar 103a. The traction hook 103b can be used to hold the surgical site for traction and pulling.

[0038] Furthermore, the adjusting member 102 further includes an adjusting slot 102b formed on the upper side of the fixing rod 101a. One side of the adjusting slot 102b is provided as an inclined portion 102c, and the other side is provided as a vertical portion 102d.

[0039] The adjusting member 102 further includes a sliding rod 102e slidably arranged on the upper side of the adjusting column 102a, a tension spring 102f sleeved on the outside of the sliding rod 102e, an adjusting plate 102g arranged at one end of the sliding rod 102e, and an adjusting tooth 102h arranged on one side of the adjusting plate 102g. The two ends of the tension spring 102f are respectively connected to the side wall of the adjusting plate 102g and the inner wall of the adjusting column 102a. The inclined portion of the adjusting tooth 102h contacts the inclined portion 102c of the adjusting groove 102b first. Through this arrangement, when the adjusting column 102a is moved, when the adjusting column 102a is moved to the adjusting groove 102b, the adjusting tooth 102h is driven by the force of the tension spring 102f to drive the adjusting tooth 102h. 2h is squeezed toward the adjustment slot 102b. When the adjustment column 102a is continued to be pulled to both sides to slide to both sides, the inclined portion of the adjustment tooth 102h contacts the inclined portion 102c of the adjustment slot 102b, and is squeezed by the inclined portion 102c of the adjustment slot 102b, causing it to slide upward, so that it can continue to slide to both sides. When the adjustment column 102a needs to be dialed back, the vertical surface of the adjustment tooth 102h contacts the vertical portion 102d of the adjustment slot 102b, and the adjustment tooth 102h is stuck and fixed, thereby fixing the adjustment column 102a, so that the adjustment column 102a can only be pulled in one direction. When dialed back in the opposite direction, it will be locked, thereby improving the stability of the adjustment column 102a.

[0040] Preferably, the adjusting member 102 also includes a pull cover 102i fixedly mounted on the upper end of the sliding rod 102e, and the pull cover 102i is provided to facilitate pulling the sliding rod 102e upward. The adjusting member 102 also includes a return spring 102j sleeved on the outside of the fixed rod 101a, and the return spring 102j can facilitate applying a return force to the adjusting column 102a. On the one hand, after the position of the adjusting column 102a is adjusted, the return spring 102j can apply a continuous reverse force to the adjusting column 102a so that the vertical surface of the adjusting tooth 102h inside the adjusting column 102a and the vertical portion 102d of the adjusting groove 102b are in continuous contact and clamping, thereby improving the stability of the adjusting column 102a. At the same time, the adjusting column 102a can be reset after the locking fixation of the adjusting tooth 102h is released.

[0041] As can be seen from the above, when in use, after being hooked by the traction hook 103b according to the surgical site, the adjustment column 102a is pulled to both sides for traction. During the pulling process, when the adjustment column 102a is moved to the adjustment groove 102b, the adjustment tooth 102h is driven by the force of the tension spring 102f to squeeze the adjustment tooth 102h toward the adjustment groove 102b. When the adjustment column 102a is continued to be pulled to both sides and slides to both sides, the inclined portion of the adjustment tooth 102h contacts the inclined portion 102c of the adjustment groove 102b, and is pressed by the inclined portion 102c of the adjustment groove 102b. c is squeezed to make it slide upward, so that it can continue to slide to both sides. When the adjusting column 102a needs to be dialed back, the vertical surface of the adjusting tooth 102h contacts the vertical part 102d of the adjusting slot 102b, and the adjusting tooth 102h is locked and fixed, thereby fixing the adjusting column 102a, so that the adjusting column 102a can only be pulled in one direction. When dialed back in the opposite direction, it will be locked, thereby improving the stability of the adjusting column 102a, thereby improving the stability of the traction device during the operation, ensuring the clarity of the surgical field and the convenience of operation.

[0042] Example 2: As shown in the attached Figure 2 To the attached Figure 6 As shown: This embodiment is basically the same as the previous embodiment, with the difference that the retractor 103 includes a ring 103a slidably arranged on the outside of the adjusting column 102a and a traction hook 103b rotatably installed on the lower end of the ring 103a. The traction hook 103b can be used to clamp the surgical site for traction and pulling. The design of the traction hook 103b enables it to firmly hook the surgical site, thereby achieving a stable traction effect. The retractor 103 also includes a locking bolt 103c threadedly arranged on the outside of the ring 103a and a threaded hole 103d opened on the side surface of the adjusting column 102a. The locking bolt 103c extends into the threaded hole 103d and is threaded with it. The locking bolt 103c and the threaded hole 103d can facilitate real-time adjustment of the position of the ring 103a, and it is quickly fixed by the locking bolt 103c.

[0043] Furthermore, the adjusting member 102 also includes a sliding rod 102e slidably arranged on the upper side of the adjusting column 102a, a tension spring 102f sleeved on the outside of the sliding rod 102e, an adjusting plate 102g arranged at one end of the sliding rod 102e, and an adjusting tooth 102h arranged on one side of the adjusting plate 102g. The two ends of the tension spring 102f are respectively connected to the side wall of the adjusting plate 102g and the inner wall of the adjusting column 102a. The inclined portion of the adjusting tooth 102h first contacts the inclined portion 102c of the adjusting groove 102b. Through this arrangement, when the adjusting column 102a is moved, when the adjusting column 102a is moved to the adjusting groove 102b, the adjusting tooth 102h is driven by the force of the tension spring 102f to adjust the tooth 102h is squeezed toward the adjustment slot 102b. When the adjustment column 102a is continued to be pulled to both sides to slide to both sides, the inclined portion of the adjustment tooth 102h contacts the inclined portion 102c of the adjustment slot 102b, and is squeezed by the inclined portion 102c of the adjustment slot 102b, causing it to slide upward, so that it can continue to slide to both sides. When the adjustment column 102a needs to be dialed back, the vertical surface of the adjustment tooth 102h contacts the vertical portion 102d of the adjustment slot 102b, and the adjustment tooth 102h is locked and fixed, thereby fixing the adjustment column 102a, so that the adjustment column 102a can only be pulled in one direction. When dialed back in the opposite direction, it will be locked, thereby improving the stability of the adjustment column 102a.

[0044] Preferably, multiple threaded holes 103d are provided and linearly distributed around the circumference of the adjustment column 102a. This arrangement enhances the adjustable flexibility of the collar 103a. During actual use, the surgeon can secure the collar 103a within the appropriate threaded hole 103d by rotating the locking bolt 103c according to surgical requirements. This design not only improves the stability of the distractor 103 but also allows the surgeon to more conveniently adjust the collar 103 according to the surgical process. Two locking bolts 103c are provided, one on each side of the collar 103a, enhancing the installation stability of the collar 103a.

[0045] As can be seen from the above, during use, the position of the ring 103a is moved according to the needs of the operation. After moving to the appropriate position, the locking bolt 103c is turned to quickly fix the ring 103a, and then the position of the ring 103a is fixed and preoperative traction is started. When in use, two locking bolts 103c are provided and they are respectively provided on both sides of the ring 103a. This setting can improve the installation stability of the ring 103a, and then traction is started by toggling the adjustment piece 102.

[0046] Example 3: As shown in the attached Figure 7As shown: On the basis of Example 1, the lifting member 104 includes a base plate 104a, a limiting rod 104b fixedly mounted on the upper side of the base plate 104a, and a threaded rod 104c rotatably arranged on the upper side of the base plate 104a. The threaded rod 104c passes through the lifting platform 101c and is threaded therewith, and the limiting rod 104b passes through the lifting platform 101c and is slidably arranged therewith. A driving motor is arranged inside the base plate 104a, and the output end of the driving motor is fixedly connected to the threaded rod 104c through a coupling. The threaded rod 104c is driven to rotate by starting the driving motor, and the rotation of the threaded rod 104c drives the lifting platform 101c to move up and down, thereby realizing height adjustment of the device. The limiting rod 104b provided can improve the limiting effect of the lifting platform 101c, thereby improving the stability of the device during the lifting process.

[0047] Preferably, the lifting member 104 further includes a limiting platform 104d fixedly mounted on the upper side of the limiting rod 104b. The limiting platform 104d can be used to prevent the lifting platform 101c from falling off, thereby reducing the possibility of it falling off due to being too high.

[0048] Furthermore, the adjusting member 102 also includes a sliding rod 102e slidably arranged on the upper side of the adjusting column 102a, a tension spring 102f sleeved on the outside of the sliding rod 102e, an adjusting plate 102g arranged at one end of the sliding rod 102e, and an adjusting tooth 102h arranged on one side of the adjusting plate 102g. The two ends of the tension spring 102f are respectively connected to the side wall of the adjusting plate 102g and the inner wall of the adjusting column 102a. The inclined portion of the adjusting tooth 102h first contacts the inclined portion 102c of the adjusting groove 102b. Through this arrangement, when the adjusting column 102a is moved, when the adjusting column 102a is moved to the adjusting groove 102b, the adjusting tooth 102h is driven by the force of the tension spring 102f to adjust the tooth 102h is squeezed toward the adjustment slot 102b. When the adjustment column 102a is continued to be pulled to both sides to slide to both sides, the inclined portion of the adjustment tooth 102h contacts the inclined portion 102c of the adjustment slot 102b, and is squeezed by the inclined portion 102c of the adjustment slot 102b, causing it to slide upward, so that it can continue to slide to both sides. When the adjustment column 102a needs to be dialed back, the vertical surface of the adjustment tooth 102h contacts the vertical portion 102d of the adjustment slot 102b, and the adjustment tooth 102h is locked and fixed, thereby fixing the adjustment column 102a, so that the adjustment column 102a can only be pulled in one direction. When dialed back in the opposite direction, it will be locked, thereby improving the stability of the adjustment column 102a.

[0049] Preferably, the adjusting member 102 also includes a pull cover 102i fixedly mounted on the upper end of the sliding rod 102e, and the pull cover 102i is provided to facilitate pulling the sliding rod 102e upward. The adjusting member 102 also includes a return spring 102j sleeved on the outside of the fixed rod 101a, and the return spring 102j can facilitate applying a return force to the adjusting column 102a. On the one hand, after the position of the adjusting column 102a is adjusted, the return spring 102j can apply a continuous reverse force to the adjusting column 102a so that the vertical surface of the adjusting tooth 102h inside the adjusting column 102a and the vertical portion 102d of the adjusting groove 102b are in continuous contact and clamping, thereby improving the stability of the adjusting column 102a. At the same time, the adjusting column 102a can be reset after the locking fixation of the adjusting tooth 102h is released.

[0050] Furthermore, the retractor 103 includes a ring 103a slidably arranged on the outside of the adjusting column 102a and a traction hook 103b rotatably installed at the lower end of the ring 103a. The traction hook 103b can be used to clamp the surgical site for traction and pulling. The design of the traction hook 103b enables it to firmly hook the surgical site, thereby achieving a stable traction effect. The retractor 103 also includes a locking bolt 103c threadedly arranged on the outside of the ring 103a and a threaded hole 103d opened on the side surface of the adjusting column 102a. The locking bolt 103c extends into the threaded hole 103d and is threaded with it. The locking bolt 103c and the threaded hole 103d can facilitate real-time adjustment of the position of the ring 103a, and it is quickly fixed by the locking bolt 103c.

[0051] As can be seen from the above, during use, when the height of the device needs to be adjusted, the internal drive motor is started, the drive motor drives the threaded rod 104c to rotate, and the rotation of the threaded rod 104c drives the lifting platform 101c to move up and down, thereby realizing the height adjustment of the device. The setting of the limit rod 104b can enhance the limiting effect of the lifting platform 101c, thereby improving the stability of the device during the lifting process.
