Problems solved by technology

[0002] Currently, laryngeal CO 2 During laser surgery, an assistant is usually needed to help press the patient's thyroid cartilage down and fix the thyroid cartilage. If the operation takes a long time, due to hand fatigue, it is often necessary to replace assistants to press in turn, which not only wastes manpower, but also due to hand strength. Instability, with the extension of the pressing time, it will cause the movement of the surgical field, which seriously affects the micromanipulation and easily causes secondary damage
After the operator depresses and fixes the thyroid cartilage to fully expose the glottis, when an assistant is needed to assist in replacing the compression, due to the difference in hand strength and angle between the assistant and the operator, it is difficult to achieve the ideal exposure level in a short period of time, which seriously prolongs the operation. operation time
In addition, sometimes due to excessive hand strength, the patient's cartilage joints will be dislocated, resulting in joint movement disorders and hoarseness, which poses a safety hazard

Embodiment Construction

[0016] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0017] Such as figure 1 , figure 2 as well as image 3 Shown are the front view, top view and left view of the thyroid cartilage fixator for laryngeal surgery. The thyroid cartilage fixator for throat surgery of the present invention is mainly equipped with lower columns 2 that can move longitudinally relative to the base plate 1 on the left and right sides of the base plate 1, specifically, the left and right sides of the base plate 1 are respectively provided with longitudinal bars. Hole 13 (particularly as figure 2 As shown), the lower ends of the two lower columns 2 are respectively embedded in the longitudinal holes 13 and can move along the longitudinal holes 13 .

[0018] The upper ends of the two lower columns 2 are respectively connected with an upper column 3 , and the upper column 3 can move up and down relative to the lower column 2 a...

Abstract

The invention provides a thyroid cartilage fixing device for a laryngeal operation. Lower columns capable of moving vertically are installed on a base plate, the upper ends of the two lower columns are connected with upper columns respectively, and the upper columns can be moved and fixed. A transverse adjusting screw and a guide polish rod which are parallel are arranged between the two upper columns, the transverse adjusting screw can rotate, a connection seat is arranged on the guide polish rod, and the transverse adjusting screw can be in threaded fit with a transverse screw hole of the connection seat. One end of a vertical adjusting screw is installed in a vertical screw hole of the connection seat, a pointer box capable of rotating is installed at the other end, a spring seat is installed in the pointer box, the upper end and the lower end of a pressure spring abut against the vertical adjusting screw and the spring seat respectively, and the spring seat is provided with a pointer and an elastic fixed clamping claw. The thyroid cartilage fixing device for the laryngeal operation is provided according to the actual requirement of the laryngeal operation and achieves the aims of saving operation assistants, ensuring operation effects, avoiding medical accidents, improving operation efficiency and reducing pains of patients.
