Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary device technology, and in particular to an external fixation suspension traction device for transoral endoscopic thyroidectomy. Background Technology

[0002] Thyroid diseases are common and frequently occurring in clinical practice. Surgery is the main treatment for thyroid diseases. Transoral endoscopic thyroidectomy is a commonly used surgical procedure in clinical practice. This procedure is characterized by small incisions, definite surgical results, and rapid postoperative recovery, while leaving no obvious scars on the patient's body.

[0003] However, because the incision for this type of minimally invasive surgery is located in the oral vestibule, the incision is small, the surgical area is small, and the incision is far from the surgical area. The surgeon can only perform gland removal, lymph node dissection, suturing, and hemostasis in a nearly closed space using a trocar with a maximum diameter of 10mm. When using traditional suspension traction surgical instruments, the instruments are relatively fixed, have limited adjustability, are bulky, difficult to install, and also obstruct the surgical area. Insufficient exposure of the surgical area and incomplete protection of surrounding tissues during the operation increase the surgical risk and difficulty. Summary of the Invention

[0004] To address the aforementioned problems, the purpose of this utility model is to provide an external fixation suspension traction device for transoral endoscopic thyroidectomy, which, under the conditions of different patient body shapes and different traction positions, uses sagittal, coronal and horizontal rotation around the patient's head and neck for precise external fixation traction.

[0005] The technical solution adopted in this utility model is as follows:

[0006] The present invention discloses an external fixation and suspension traction device for transoral endoscopic thyroidectomy, comprising a portal frame, connecting rod I, connecting rod II, a fixator, and suspension hooks; the connecting rod I is vertically disposed behind one side of the portal frame; the connecting rod I is fixedly connected to one vertical side of the portal frame via the connecting rod II; the two sides of the connecting rod II are respectively fixedly connected to the connecting rod I and the vertical side of the portal frame via the fixator in a cross shape; the suspension hooks are correspondingly fixedly connected to each side of the portal frame.

[0007] Furthermore, the fixture is a double-hole rotating universal fixing structure.

[0008] Furthermore, the suspension hook includes an open ram's horn hook and an adjustable retainer; the open ram's horn hook is threaded onto one side of the adjustable retainer.

[0009] Furthermore, the adjustable retainer includes a retaining ring and an adjusting wrench; the retaining ring is composed of two semi-circular parts, with one end of each semi-circular part hinged to the other, and the other end of each semi-circular part having a corresponding retaining seat; the adjusting wrench is threadedly connected to the end retaining seats of the two semi-circular parts; the open ram's horn hook is threadedly connected to the outside of one semi-circular part.

[0010] Furthermore, both connecting rod I and connecting rod II are hollow tube structures with closed ends.

[0011] Furthermore, the portal frame is a hollow tube structure with both ends closed.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention allows for sagittal, coronal, and horizontal rotation around the patient's head and neck. The traction site and tissues can be flexibly adjusted according to the surgeon's habits and the patient's height and physique. After installation, during surgery, the position and direction of the suspension hooks on the portal frame, as well as the position, direction, and length of the open ram's horn hooks on the suspension hooks, can be adjusted at any time, allowing for large-scale, small-scale, and minute-scale adjustments. Unlike traditional suspension hook adjustments, this method does not require disruption of the surgical dressing, meeting the requirements of aseptic surgical techniques. It is simple to operate and maintain. While satisfying the requirements of surgical area traction exposure and tissue protection, it also reduces surgical difficulty and risks, significantly shortens surgical time, and reduces patient treatment costs.
