Abstract
Description
Technical Field
[0001] This utility model relates to the field of thyroid surgical instruments, specifically an improved omnidirectional retractor for thyroid surgery. Background Technology
[0002] Currently, clinical surgeries for the larynx and neck (such as thyroid surgery) generally involve manual retraction using a handheld retraction device. This method has several drawbacks during surgery:
[0003] 1. Fixed position, difficult to adjust;
[0004] 2. The retraction points are mostly concentrated in the throat area, and the retraction device is far from the retraction incision site, making it difficult to control the traction force;
[0005] 3. It requires manpower to pull, which is time-consuming and laborious;
[0006] 4. Neck surgery has a relatively small operating space and delicate tissue structure. Exposing the surgical field may require traction exposure in multiple directions at the same time, which may easily lead to staff shortages and the risk of hindering the surgeon's operation.
[0007] 5. The recurrent laryngeal nerve is located on the posterolateral side of the trachea. Simple traction cannot fully expose the recurrent laryngeal nerve. Therefore, external instruments are needed to actively push the trachea a short distance to the opposite side of the surgery. Currently, manual pushing or pulling is used, which makes it difficult to ensure the continuity and stability of the surgeon's operation. Uneven force may cause the traction tissue to slip and cause accidental nerve damage.
[0008] 6. Manual operation may cause pressure sores due to fatigue or other reasons, which may result from the surgeon's limbs pressing on the patient's head and face, increasing the patient's medical burden;
[0009] To address the aforementioned technical problems, prior art publication number CN 210990463 U discloses a thyroid surgery retraction device. Although it can solve the above problems, its flexibility is still relatively poor, and there are some limitations in its use. Utility Model Content

Detailed Implementation
[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] Please see Figure 1 — Figure 7An improved omnidirectional retractor for thyroid surgery includes a fixed base 100, height adjustment posts 200, an arc-shaped guide rail 300, an arc-shaped guide platform 400, and a retractor assembly 500. Firstly, multiple sets of height adjustment posts 200 are fixedly connected to the arc-shaped guide rail 300. The bottom end of each set of height adjustment posts 200 is fixedly connected to the fixed base 100. The fixed base 100 secures the instrument to the bed. Specifically, the fixed base 100 includes an arc-shaped clamping frame 101, a fixing stud 102, a knob A103, and a friction... The friction plate A104, i.e., the arc-shaped clamping frame 101 is provided with a clamping area 105, and the arc-shaped clamping frame 101 is threaded with a fixing stud 102. The fixing stud 102 is fixedly connected to the end of the clamping area 105 with a friction plate A104, and the other end of the fixing stud 102 is fixedly connected to a knob A103. In this way, the edge of the bed can be extended into the clamping area 105. By rotating the knob A103, the friction plate A104 is raised until the friction plate is in close contact with the bed, thus realizing the fixing function of the fixed base 100.
[0033] Furthermore, the height of the arc-shaped guide rail 300 can be adjusted via the height adjustment column 200. In this embodiment, the height adjustment column 200 includes a fixed cylinder 201, a moving cylinder 202, a fastening stud 203, and a knob B204.
