Problems solved by technology

[0003] The laparoscopic thyroid surgery retractor is a retractor used for endoscopic surgery during thyroid surgery. The existing retractor has a simple structure. When the retractor moves into the endoscope, there is a hidden danger that the sharp part of the retractor head will scratch the patient. , and in the process of use, since the handle of the retractor is cylindrical, it is not easy to identify the specific position of the hook head, which affects the operation

Embodiment 1

[0022] The present embodiment provides a specific structure of a laparoscopic thyroid surgery retractor, such as Figure 1-3 As shown, the drag hook body 13 is included, the drag hook body 13 includes a handle 1, a connecting rod 3 and a hook head 5, the handle 1 is installed on one end of the connecting rod 3, the hook head 5 is installed on the other end of the connecting rod 3, and the drag hook body 13 is outside Under the constraints, there are a first form and a second form. The first form is the state where the hook head 5 is unfolded, and the second form is the state where the hook head 5 is folded. The drag hook body 13 can be folded from the first form to the second form under control.

[0023] By adopting the above technical solutions:

[0024] Because the draw hook body 13 has a first form and a second form under the restriction of external constraints, and the first form is the state in which the hook head 5 is unfolded, and the second form is a state in which the...

Embodiment 2

[0026] The present embodiment provides a specific structure of a laparoscopic thyroid surgery retractor, such as Figure 1-3 As shown, the drag hook body 13 is included, the drag hook body 13 includes a handle 1, a connecting rod 3 and a hook head 5, the handle 1 is installed on one end of the connecting rod 3, the hook head 5 is installed on the other end of the connecting rod 3, and the drag hook body 13 is outside Under the constraints, there are a first form and a second form. The first form is the state where the hook head 5 is unfolded, and the second form is the state where the hook head 5 is folded. The drag hook body 13 can be folded from the first form to the second form under control.

[0027] One end outer surface of the connecting rod 3 is provided with a storage groove 4, and one end of the hook head 5 is rotated and installed in the storage groove 4 through the rotating shaft 8. When the draw hook body 13 is in the first form, the hook head 5 is deployed outside ...

Embodiment 3

[0032] The present embodiment provides a specific structure of a laparoscopic thyroid surgery retractor, such as Figure 1-3 As shown, the drag hook body 13 is included, the drag hook body 13 includes a handle 1, a connecting rod 3 and a hook head 5, the handle 1 is installed on one end of the connecting rod 3, the hook head 5 is installed on the other end of the connecting rod 3, and the drag hook body 13 is outside Under the constraints, there are a first form and a second form. The first form is the state where the hook head 5 is unfolded, and the second form is the state where the hook head 5 is folded. The drag hook body 13 can be folded from the first form to the second form under control.

[0033] A locking hook mechanism is also provided inside the connecting rod 3 , and the locking hook mechanism is used to restrict the hook head 5 inside the receiving groove 4 when the drag hook body 13 is in the second shape.

[0034] The locking hook mechanism includes a tablet 10 ...

Abstract

The invention discloses an endoscopic thyroid surgery retractor. The endoscopic thyroid surgery retractor comprises a retractor body, wherein the retractor body comprises a handle, a connecting rod and a retractor head, the handle is mounted at one end of the connecting rod, the retractor head is mounted at the other end of the connecting rod, and the retractor body has a first form and a second form under the limitation of external constraint; and the first form is the unfolded state of the retractor head, the second form is the folded state of the retractor head, and the retractor body can be controllably folded into the second form from the first form. The invention is suitable for a medicinal device. When the retractor is used, in the process that the retractor head extends into the endoscope, the endoscope head can be folded; and when the retractor head completely enters the endoscope, the retractor head is opened through other instruments in the endoscope, so that the retractor head is unfolded, the situation that a patient is punctured by the retractor head in the process that the retractor stretches into the endoscope is avoided, and the safety of the endoscopic thyroid surgery retractor is improved.
