[0002] Head and neck surgery is an important branch of otolaryngology, focusing on the treatment of various diseases of the head and neck, including tumors, congenital diseases, inflammatory diseases, vascular diseases, thyroid and parathyroid diseases, and salivary gland diseases. These surgeries typically aim to completely remove tumors while preserving as much of the organ's basic function as possible to improve patient survival rates and quality of life.

[0003] Laparoscopic techniques in head and neck surgery are minimally invasive surgical methods that allow surgeons to access the surgical area through small incisions and perform procedures using a laparoscope and specialized surgical instruments. Compared to traditional open surgery, this technique offers advantages such as less trauma, less bleeding, faster postoperative recovery, and better aesthetics. Currently, there are no dedicated laparoscopic traction devices for head and neck surgery. Using traditional laparoscopic traction systems presents the following problems: 1. Complex instrument structure, difficult assembly and adjustment; 2. Large size, cumbersome and difficult to operate, restricting surgeon positioning; 3. Limited surgical field exposure.

The vertical rod 101 and the horizontal rod 102 are hinged, and a locking mechanism 103 is provided at the hinge. The angle between the vertical rod 101 and the horizontal rod 102 is adjustable.

[0030] like Figure 1 As shown, the operating table fixation device 2 is mounted on the vertical rod 101, and is used to connect the operating table. Figure 2 As shown, the operating table fixation device 2 includes an operating table connecting part 201 and a support rod connecting part 202. The operating table connecting part 201 and the support rod connecting part 202 are rotatably connected, and the angle between the operating table connecting part 201 and the support rod connecting part 202 is adjustable. Figure 3 As shown, the operating table connecting part 201 and the support rod connecting part 202 are connected by a rotating ball joint, and the angle between the operating table connecting part 201 and the support rod connecting part 202 can be adjusted by rotation. The operating table connecting part 201 includes a first U-shaped connector 2011, and a first fastening bolt 2012 is provided on the side of the first U-shaped connector 2011. The U-shaped connector 2011 is used to snap onto the headboard or side of the operating table and is fastened by the first fastening bolt 2012. The support rod connecting part 202 has a through hole 2022, into which the vertical rod 101 is inserted and fastened by a second fastening bolt 2021.

[0031] like Figure 1As shown, the traction device bracket 3 includes a support rod connector 301, which is mounted on the crossbar 102. The lower end of the support rod connector 301 is connected to a rack and pinion drive assembly 302, and the lower end of the rack and pinion drive assembly 302 is connected to a three-pronged hook 303.

[0032] The support rod connector 301 is fitted onto the crossbar 102. The support rod connector 301 can move axially along the crossbar 102 and rotate circumferentially along the crossbar 102. By rotating and laterally moving the support rod connector 301, the relative position and angle between the traction device bracket 3 and the support rod 1 can be adjusted. The structure of the support rod connector 301 is as follows: Figure 4 As shown.

[0033] like Figure 5 and 6 As shown, the rack and pinion drive assembly 302 includes a meshing rack 3021 and a gear 3022. The gear 3022 is connected to a rocker arm 3023 and is located inside a square box 3024. A first hook 3025 is provided on the top of the square box 3024. The first hook 3025 has a first strip-shaped sliding hole 3026. A first protrusion 3011 is provided at the lower end of the support rod connector 301. The rack and pinion drive assembly 302 is hung on the first protrusion 3011 through the first strip-shaped sliding hole 3026. A second protrusion 3027 is provided at the lower end of the rack 3021. A second hook 3031 is provided on the top of the three-pronged hook 303. A second strip-shaped sliding hole 3032 is provided on the second hook 3031. The three-pronged hook 303 is hung on the second protrusion 3027 through the second strip-shaped sliding hole 3032. The horizontal opening width of the 303 three-pronged hook is adjustable.

[0034] By rotating the rocker arm 3023 to adjust the relative position of the rack 3021 and gear 3022, the position of the three-pronged pull hook 303 can be adjusted vertically, i.e., its position in the y-axis direction. By moving the support rod connector 30 laterally to adjust the relative position of the traction device bracket 3 and the support rod 1, the position of the three-pronged pull hook 303 can be adjusted laterally, i.e., its position in the x-axis direction. By rotating the support rod connector 30 to adjust the relative angle between the traction device bracket 3 and the support rod 1, the position of the three-pronged pull hook 303 can be adjusted in the z-axis direction, thus achieving three-dimensional adjustment of the position of the three-pronged pull hook 303. The three-pronged pull hook 303 can also be horizontally adjusted to widen the surgical field.

[0035] like Figure 1 and Figure 7As shown, the upper end of the flexible shaft endoscope holder 4 is mounted on the crossbar 102, and the lower end is used to mount the endoscope.

The holder fixing part 401 includes a second U-shaped connector 4011, and a third fastening bolt 4012 is provided on the side of the second U-shaped connector 4011. The crossbar 102 is embedded in the second U-shaped connector 4011 and fastened by the third fastening bolt 4012. The endoscope fixing part 403 is connected to the bottom of the flexible shaft 402 by a fourth fastening bolt 4031, and an endoscope mounting hole 4032 is provided on the endoscope fixing part 403. The flexible shaft 402 includes a flexible inner core and several rigid rings 4021 sleeved around the flexible inner core. The rigid rings 4021 are cylindrical, with one end of each ring having a spherical surface 40211, and all the spherical surfaces 40211 of the rigid rings 4021 facing the same direction. A fastening rocker arm 4022 is provided at the top of the flexible inner core. By rotating the fastening rocker arm 4022, the flexible inner core is tightened or loosened. When the flexible inner core is tightened, the rigid rings 4021 are in close contact, thereby hardening the flexible shaft 402. When the flexible inner core is loosened, the spacing between the rigid rings 4021 increases, thereby softening the flexible shaft 402.

[0036] This utility model of a head and neck surgical endoscopic traction device is applied to the resection of head and neck tumors in the maxillofacial region. The usage process is as follows: First, according to... Figure 1 Assemble the various components of the operating table, fixing the operating table fixture 2 to the head or side of the operating table and securing it firmly. Install the endoscope on the flexible shaft endoscope support, and adjust the endoscope to the appropriate position by adjusting the stiffness of the flexible shaft 402. Adjust the position of the support rod connector and rack and pinion drive assembly in the traction device support, thereby adjusting the three-grasp hook to the appropriate position. Make an incision at the tumor site on the patient's skin, insert the three-grasp hook to form a surgical channel in the patient's skin, and then perform the head and neck tumor resection surgery.
