Problems solved by technology

[0002] In clinical practice, when performing head and neck surgery on patients, in order to obtain a better surgical field of view, additional medical staff are generally required to assist in pulling the operation port. Posture, personnel are prone to fatigue, and the number of personnel is required to be large, and the operation is inconvenient. When the assistant is tired, the hands are prone to slippery, which affects the operation. In severe cases, it will threaten the life safety of the patient. Therefore, an auxiliary operation is needed. The retractor device is used to replace the manual stretching of the surgical opening; the pulling device needs to be equipped with multiple retractors to pull the surgical openings of different sizes, and can pull at multiple angles at the same time; in addition, the pulling device needs to take into account the actual use and needs to be convenient. Adjust height, horizontal distance, and horizontal rotation angle

Embodiment 1

[0036] The specific application of the present invention when used as a retractor for head and neck surgery is as follows: figure 2 As shown, in the actual use process, the C-shaped frame 101 of the base is stuck on the steel structure under the operating bed, and the threaded knob 9 on the C-shaped frame 101 is screwed to move the backing plate 102 to the top of the C-shaped frame 101 to This sandwiches the steel structure between the C-frame 101 and the backing plate 102, thereby securing the device to the steel structure on the side of the operating table.

Embodiment 2

[0038] The specific application of the present invention when used as a retractor for head and neck surgery is as follows: figure 1 As shown, the upper end of the sleeve 2 is hinged with a rotating sleeve 3, and the lower end to the middle of the threaded column 4 penetrates through the rotating sleeve 3 and then extends into the inside of the sleeve 2, and the threaded column 4 can be extended by screwing the rotating sleeve 3. In or out of the sleeve 2, so as to realize the rise and fall of the connecting frame 6, thereby realizing the height adjustment of the drag hook 8.

Embodiment 3

[0040] The specific application of the present invention when used as a retractor for head and neck surgery is as follows: Figure 3-4 As shown, the cylinder 501 of the adapter 5 is provided with an arc-shaped groove 502 with an arc of 120°, and a ratchet 507 is provided on the side wall of the cylinder 506, and the cylinder 506 can rotate in the cylinder 501. The rotation range of the cylinder 506 is limited within 120° by the ratchet 507 and the arc-shaped groove 502; 24 blocks 503 are evenly arranged in the arc-shaped groove 502, and the blocks 503 are connected to the arc-shaped groove 501 by a spring 504 Inside, the ratchet 507 will collide with the block 503 during the rotation process. Whenever the ratchet 507 rotates 5°, the block 503 is bounced by the spring 504 and hits the cylinder 506 to make a sound, which reminds the operator that the rotation has been completed. 5°, so as to help the operator to rotate the connecting frame 4 to a specified angle; after reaching ...

Abstract

The invention discloses a head and neck operation drag hook which is characterized by comprising a base, a sleeve, a rotating sleeve, a threaded column, an adapter, a connecting frame, a supporting arm, a drag hook base, a drag hook body, a wedge and a threaded rotary knob. According to the head and neck operation drag hook, a surgical incision of a patient can be pulled when a head and neck operation is carried out, additional medical workers do not need to assist in pulling the surgical incision, waste of human resources is reduced, and hidden dangers caused by unstable manual pulling are avoided; meanwhile, the use number of the drag hooks can be adjusted according to the actual use condition, and the drag hooks which do not work are contracted in the drag hook base; besides, the height, the horizontal rotation specified angle and the vertical rotation angle of the drag hook can be adjusted according to requirements, the drag hook can move in the horizontal plane, and the drag hook can make a sound when rotating in the horizontal direction to help an operator to control the rotation angle.
