[0016] The present invention will be described in further detail below with reference to the accompanying drawings.

[0017] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings, wherein the same components are represented by the same reference numerals.

[0018] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the accompanying drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0019] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0020] Combined with attachment Figure 1 -Attached Figure 3 An adjustable retractor for thyroid surgery includes a retractor body, which includes a connecting part 1, a hanging part 2 and a retractor part 3. The hanging part 2 and the retractor part 3 are respectively vertically fixed to the upper and lower ends of the connecting part 1. The retractor part 3 is away from the upper part of one end of the connecting part 1 and is relatively rotatable with two expansion hooks 4. Both expansion hooks 4 are provided with a first hollow 5.

[0021] In one embodiment, both sides of the hook portion 3 away from one end of the connecting portion 1 are provided with mounting grooves 6 for accommodating the expansion hooks 4 on both sides, and the expansion hooks 4 on both sides are rotatably arranged in the mounting grooves 6 on both sides through the pins 7. In this embodiment, the rotatable installation design of the expansion hook 4 is the key to realizing the hook function. Through the pins 7 in the mounting grooves 6 on both sides, the two expansion hooks 4 can rotate flexibly and stably. This design not only ensures that the expansion hook can be smoothly unfolded when needed to expand the surgical field of view, but also ensures that it can fit tightly on the hook portion 3 in the non-working state, maintaining the compactness of the overall structure. In addition, the pin 7, as a connection point, also has a certain load-bearing capacity, which can withstand the tension and pressure that may be generated during the operation, ensuring the stability and safety of the hook.

[0022] In one embodiment, a mounting cavity 8 is provided inside the retractor portion 3, and a drive rod 9 is provided in a sliding and retractable manner inside the mounting cavity 8. The outer end of the drive rod 9 extends to the outside of the mounting cavity 8 and is bent upward to form a handle 10. One end of the drive rod 9 is provided with a drive plate 11 extending between the mounting grooves 6 on both sides. Two V-shaped connecting plates 12 are rotatably provided on the drive plate 11, and the ends of the two V-shaped connecting plates 12 away from the drive plate 11 are rotatably connected to the expansion hooks 4 on both sides. The drive mechanism and transmission structure in this embodiment are cleverly designed. Through the synergistic effect of the sliding and retractable drive rod 9 and the internal drive plate 11 and V-shaped connecting plate 12, remote and precise control of the expansion hook 4 is achieved. The doctor only needs to push the drive rod 9 by operating the handle 10 to drive the entire transmission system to work, so that the expansion hook 4 rotates outward and expands according to the predetermined trajectory. This design not only simplifies the operation process and improves surgical efficiency, but also reduces the uncertainty of human operation through mechanical transmission, ensuring the accuracy of the operation.

[0023] In one embodiment, an extension plate 13 is provided above the mounting slot 6. A stopper is formed between the extension plate 13 and the mounting slot 6 to limit the vertical movement of the expansion hook 4. To ensure the stability and accuracy of the expansion hook during deployment, this embodiment includes an extension plate 13 above the mounting slot 6, forming a stopper together with the mounting slot 6. This design effectively limits the vertical movement of the expansion hook, allowing it to maintain a stable posture during deployment, thereby improving the clarity of the surgical field. This stopper also enhances the stability of the retractor's overall structure, contributing to improved safety during surgery.

[0024] In one embodiment, a plurality of suspension holes 14 are formed along the extension of the suspension portion 2. The design of the suspension portion 2 and the suspension holes 14 thereon greatly facilitates the securement of the retractor to the operating table. The surgeon can flexibly select the location and number of suspension holes 14 to adjust the height and angle of the retractor according to surgical needs. This design not only increases the flexibility of surgical preparation but also helps optimize the surgical operating space, creating a more comfortable and efficient working environment for the surgeon. Furthermore, the design of the suspension holes takes into account the cleaning, disinfection, and storage requirements of the retractor, making the entire device easier to maintain and service.

[0025] In one embodiment, a second hollow 15 corresponding to the first hollow 5 is provided at one end of the hook portion 3 away from the connecting portion 1. The design of the first hollow 5 and the second hollow 15 on the hook portion 3, as well as the suction tube 16 provided in the extension direction of the bottom, together constitute a cleaning system during surgery. The presence of the first hollow 5 and the second hollow 15 helps to drain liquids and tissue fragments in the surgical area and keep the surgical field clear. The suction tube 16 can further absorb these liquids and fragments to ensure the cleanliness and sterility of the surgical area. This design not only improves the smoothness of the surgical operation, but also helps to reduce the risk of postoperative infection. At the same time, the outward bending design of the suction tube 16 also facilitates connection and use with the suction device.

[0026] Working Principle: First, during the surgical preparation phase, the surgeon can flexibly adjust the retractor's position and height on the operating table through the pre-set suspension holes 14 on the suspension portion 2 to accommodate the needs of different surgical scenarios. At this point, the retractor is in its unfolded state, with the two expansion hooks 4 tightly fitted within the mounting slots 6 of the retractor portion 3. This not only maintains the overall compactness for easy portability, storage, and preoperative disinfection, but also ensures the cleanliness and sterility of surgical instruments.

[0027] After the operation begins, the doctor accurately inserts the retractor body through the patient's axillary incision and slowly extends it into the surgical area of the neck. During this process, the retractor part 3 and its two unexpanded expansion hooks 4 are initially positioned in the incision to prepare for the subsequent field of view expansion.

[0028] To effectively expand the surgical field of view, the surgeon gently pushes the drive rod 9 by operating the handle 10. The drive rod 9 slides smoothly within the mounting cavity 8 within the retractor 3. This action, through the principle of mechanical transmission, drives the drive plate 11 mounted therein to move forward synchronously. The movement of the drive plate 11 further causes the two V-shaped connecting plates 12 to rotate. These two V-shaped connecting plates 12 serve as intermediate transmission components, with their ends rotatably connected to the drive plate 11 and the expansion hook 4, respectively. Therefore, they effectively convert the linear motion of the drive rod into the rotational motion of the expansion hook.

[0029] As the V-shaped connecting plate 12 rotates, the expansion hooks 4 on both sides are pulled outward and deployed synchronously, thereby gradually expanding the exposed area around the surgical incision. The first hollow design 5 on the expansion hooks 4 not only reduces the overall weight of the instrument, but also facilitates the drainage of blood, tissue fluid, and other fluids during surgery, maintaining a clear surgical field of view.

[0030] Furthermore, a suction tube 16 extending from the bottom of the retractor 3 effectively draws exudate, blood, or other fluids from the incision during surgery, maintaining a clear and dry surgical field and reducing the risk of postoperative infection. The end of the suction tube 16, away from the second hollow portion 15, is bent outward, facilitating connection to an external suction device for smooth fluid drainage.

[0031] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
