Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a thyroid dissection device for endoscopic thyroid surgery. Background Technology

[0002] Endoscopic thyroidectomy is a minimally invasive technique that involves removing thyroid tissue through small incisions made outside the neck, such as in the armpit, areola, or oral vestibule, using endoscopic equipment. The main advantage of endoscopic thyroidectomy is its cosmetic effect, as it avoids leaving scars on the neck, which is very attractive to patients concerned about appearance, especially young women. Furthermore, the magnification provided by the endoscope allows for clearer identification and protection of important structures, such as the recurrent laryngeal nerve and parathyroid glands, thus reducing the risk of intraoperative damage. The dissectors used in endoscopic thyroidectomy are surgical instruments specifically designed for minimally invasive surgery, enabling surgeons to precisely separate thyroid tissue without damaging surrounding tissues.

[0003] Currently available thyroid dissectors typically feature a fine tip and a long handle to facilitate precise manipulation with the aid of an endoscope, performing tasks such as grasping and traction. However, the puncture procedure reduces the surgical space, and existing thyroid dissectors often lack adjustable clamp angles. Furthermore, the dissector's length makes dissection within a confined space more complex and inconvenient. Existing angle-adjustable thyroid dissectors generally require complex, two-handed manipulation to change the clamp angle. This presents significant inconvenience and limitations for surgeons who must hold the instrument with both hands and adjust the dissector angle by observing the endoscope during surgery.

[0004] Therefore, a new type of thyroid dissector for endoscopic thyroid surgery is needed. The physician can hold the device with one hand and use different fingers to push and pull the various loops at the end of the device to rotate the forceps in different directions and open and close the forceps at the front end of the device. Utility Model Content

[0005] To address the aforementioned technical problems, this invention designs a thyroid dissecter for endoscopic thyroid surgery. The user can hold the device with one hand and control the opening and closing of the clamps with the thumb, while controlling the angle of the clamps with the index and middle fingers. This facilitates dissection within a narrow cavity. Furthermore, while fulfilling the above functions, the device's size will not result in a larger puncture wound for the patient, thus avoiding any impact on postoperative recovery.

[0006] To achieve the above-mentioned technical effects, this utility model is implemented through the following technical solution: a thyroid dissecting device for endoscopic thyroid surgery, comprising: a clamp, a main grip, a first angle rod, a second angle rod, an opening and closing rod, a first connecting rod, and a second connecting rod;

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model; obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1

[0028] This utility model discloses a retractor assembly for clinical use of thyroid glands, comprising a clamp 1, a main grip 2, a first angle bar 3, a second angle bar 4, an opening and closing bar 5, a first connecting rod 6, and a second connecting rod 7;

[0029] The clamping section 1 is the front working part of the peeler, consisting of a pair of jaws 101, a rotating base 102, an opening / closing base 103, a third connecting rod 104, and a fourth connecting rod 105. The jaws 101 are rotatably mounted on the rotating base 102; the rotating base 102 is connected to the front of the main gripping rod 2; the opening / closing base 103 is designed to slide inside the rotating base 102, and is connected to the end of the jaws 101 via the third connecting rod 104, and to the interior of the opening / closing base 103 at the other end, allowing the jaws 101 to open and close flexibly. The fourth connecting rod 105 connects the opening / closing base 103 and the opening / closing rod 5, further controlling the opening and closing action of the jaws 101.

[0030] The first connecting rod 6 and the second connecting rod 7 connect the rotating base 102 and the first and second angle rods 3 and 4, respectively. These links allow the movement of the rotating base 102 to be transmitted to the angle rods, enabling precise angle adjustment of the forceps 1. The first and second angle rods 3 and 4 are slidably fitted inside the main grip 2, allowing the angle rods to slide freely within the main grip 2, thus adjusting the angle of the forceps 1. To improve operational comfort and convenience, the end of the first angle rod 3 is fitted with a first pull loop 301 suitable for the size of an index finger, while the end of the second angle rod 4 is fixedly fitted with a second pull loop 402 suitable for the size of a middle finger. During assembly, these two pull loops are located at the upper and lower ends of the main grip 2, respectively, allowing the doctor to control the angle rods with their index and middle fingers, achieving flexible rotation of the forceps 1.

[0031] A third pull ring 501, sized for the thumb, is fixedly installed at the end of the opening / closing lever 5. During assembly, it is located at the rear end of the first pull ring 301 and the second pull ring 402. This allows the surgeon to control the opening / closing lever 5 with their thumb, thereby controlling the opening and closing action of the jaws 101. Furthermore, a handle 201 is fixedly installed at the lower end of the main grip lever 2. Inside the handle 201 is a fourth pull ring 202 sized for the ring and little fingers. This design provides additional stability and comfort, allowing the surgeon to hold the dissector more securely during surgery.

[0032] The operating principle and workflow of a thyroid dissector for endoscopic thyroid surgery are as follows:

[0033] When using this device, the user inserts their ring and little fingers into the fourth pull ring 202 of the handle 201, inserts their thumb into the third pull ring 501, their index finger into the first pull ring 301, and their ring finger into the second pull ring 402, and holds the device in this posture. When in use, the device is activated by pushing and pulling the third pull ring 501 with the thumb, which drives the opening and closing lever 5. Moving the opening and closing lever 5 backward causes the opening and closing seat 103 to move backward, and under the linkage of the third connecting rod 104, the jaws 101 open. Moving the opening and closing lever 5 forward causes the opening and closing seat 103 to move forward, and under the linkage of the third connecting rod 104, the jaws 101 close. Additionally, when the user pushes the first pull ring 301 forward with their index finger, the first angle lever 3 moves forward, and under the linkage of the first connecting rod 6 and the rotating seat 102, the jaws 101 bend upward. When the user pushes the second pull ring 402 forward with their middle finger, the second angle lever 4 moves forward, and under the linkage of the second connecting rod 7 and the rotating seat 102, the jaws 101 bend upward.

[0034] The device can open and close normally regardless of whether it is bent upwards, downwards, or not bent, without affecting the basic operations of clamping and peeling.

[0035] The preferred embodiments of the present invention disclosed above are only used to help illustrate the present invention. The preferred embodiments do not describe all the details in detail, nor do they limit the present invention to the specific implementation methods described.
