Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, and more specifically to a trans-axillary laparoscopic thyroid self-locking suspension hook device. Background Art

[0002] In recent years, more and more axillary laparoscopic thyroid surgeries have been performed. The current laparoscopic surgery suspension retractor is used to build a cavity. A hole is opened at the end of the retractor, and it is connected to the hook of the suspension device through the hole for traction. When replacing it, multiple people need to cooperate. One person presses down the suspension crossbar to move the hook down and maintain the changed height.

[0003] After searching, the Chinese patent with publication number CN217285888U discloses a transaxillary laparoscopic thyroid retractor suspension device, which is aimed at the problem that the nerve monitor is used to intermittently or continuously monitor the nerve function in the existing open surgery; in laparoscopic thyroid surgery, only intermittent monitoring can be performed, which is complicated during use, causing inconvenience in surgical operation and affecting surgical efficiency. The connection between the fixed rod and the suspension bar can rotate 270°, and can be rotated outward 270° when in use, so that they are in a perpendicular state for suspension; in the storage state, they can fit parallel to each other to reduce the required placement space, and the movable connecting hook can be adjusted and controlled according to the use needs, which is convenient for intraoperative operation.

[0004] The main body of the hook is connected to the suspension device through a hook. This connection method is difficult to assemble and disassemble during operation and requires a lot of force. Some existing hook devices have achieved simple assembly and disassembly, but their structural assembly stability is insufficient and cannot withstand heavy pulling, with the risk of falling off.

The movable sleeve 3 is slidably connected to the inside of the movable sleeve 3, and the outside of the horizontal rod 4 is slidably connected to the hanger 5. The bottom surface of the hanger 5 is provided with a fixing groove 6. The top surface of the movable sleeve 3 and the side surface of the hanger 5 are provided with threaded holes 7. The threaded holes 7 are threadedly connected to the inside of the threaded rod 8, and the top of the threaded rod 8 is fixedly connected to a knob 9. The hanger 5 is provided with a threaded sleeve 10, and a spiral vertical rod 11 is provided inside the threaded sleeve 10. The top of the threaded sleeve 10 is fixedly connected to a fixing knob 12, and the bottom of the spiral vertical rod 11 is provided with a self-locking mechanism.

[0028] As attached Figure 1 , 2 As shown in Figures 3, 4 and 6, the self-locking mechanism includes a self-locking device 13, which is fixed at the bottom of the spiral vertical rod 11. A hook body 14 is installed at the bottom of the self-locking device 13. A smoking pipe connecting tube 15 is fixedly connected to the outside of the hook body 14. A lock buckle 20 is fixedly connected to the top of the hook body 14. The top of the lock buckle 20 penetrates the self-locking device 13 and extends to the inside of the hook body 14. Buttons 17 are provided at the top and bottom of the self-locking device 13. A spring lock sheath 18 is installed inside the self-locking device 13. The button 17 and the spring lock sheath 18 are installed and connected by a screw 19. A screw hole 21 is opened on the surface of one side of the self-locking device 13. A fixing screw 16 is threadedly connected inside the screw hole 21. The fixing screw 16 is arranged on one side of the self-locking device 13 to facilitate double locking of the hook body 14.

[0029] As attached Figure 1 , 2 As shown in , 3, 4, 5, and 7, the cross bar 4 is slidably connected to the fixed groove 6, which is convenient for adjusting the position of the hanger 5 on the cross bar 4. The top of the spiral vertical rod 11 passes through the hanger 5 and the threaded sleeve 10 and extends to the top of the threaded sleeve 10. The hanger 5 and the threaded sleeve 10 are rotationally connected, and the inner wall of the threaded sleeve 10 and the spiral vertical rod 11 are threadedly connected, which is convenient for the rotation of the threaded sleeve 10 to drive the spiral vertical rod 11 to rise and fall inside the threaded sleeve 10, and it is convenient to adjust the height of the self-locking device 13. The cross-sectional shape of the retractor body 14 is set to be U-shaped, which is convenient for the retractor body 14 to be lifted and raised by traction from the patient's axillary incision to the approach.

[0030] Working principle of the utility model: During use, the utility model uses the retractor body 14 to pull and lift from the patient's axillary incision to the entry route, inserts the top lock buckle 20 of the retractor body 14 into the self-locking device 13, and rotates the fixing screw 16 for secondary fixation. A pair of spring lock sheaths 18 are arranged inside the self-locking device. The spring lock sheaths 18 are movable and connected to the button 17 through the fixing screw 16. Pressing the button 17 can drive the spring lock sheath 18 to rotate and move through the fixing screw 16. The retractor body 14 is a U-shaped structure, and there is a raised lock buckle 20 at the outer end of the upper plate of the retractor body 14. An inclined surface is arranged on the top of the lock buckle 20, and there is a circle of concave structure at the middle end. The spring lock sheath 18 is opened at the top of the lock buckle 20 and moves upward. The spring lock sheath 18 rebounds to the concave position in the middle and is stuck in the concave structure, so that the lock buckle 20 can no longer move, thereby fixing the hook body 14 on the hanger 5. A fixing screw 16 is provided on the side of the self-locking device 13. The end of the fixing screw 16 is close to the position of the spring lock sheath 18. After tightening the fixing screw 16 inward, it resists the spring lock sheath 18 and prevents it from moving, thereby achieving the purpose of double fixation.
