Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to an intelligent thoraco-breast approach laparoscopic thyroid surgery retractor. Background Art

[0002] In the past two decades, the incidence of benign and malignant thyroid tumors has continued to rise, and the number of patients who need surgical treatment has increased significantly. With the continuous development and maturity of laparoscopic technology, laparoscopic thyroid surgery has been widely carried out at home and abroad due to its advantages such as less trauma, fast postoperative recovery and good neck appearance, and has become one of the important options for surgical treatment of thyroid diseases.

[0003] In laparoscopic thyroid surgery via the thoraco-breast approach, full exposure of the surgical field is crucial. In addition to using an ultrasonic scalpel to separate tissues and create a cavity, and expanding the surgical operating space through carbon dioxide pneumoperitoneum, it is also necessary to use a retractor to pull apart the anterior cervical muscles located in the superficial layer of the thyroid gland to fully expose the thyroid gland and surrounding regional lymph nodes.

[0004] The retractor used in existing laparoscopic thyroid surgery is a common instrument used to pull the sternocleidomastoid muscle, strap muscle and other tissues to effectively expose the target structure of the surgery. The retractor head is a V-shaped metal strip with a thin diameter (2-3mm), made of stainless steel, and a relatively sharp tip, designed to pierce the skin and enter the surgical area. However, this traditional design has the following major problems:

[0005] 1. High risk of tissue damage: Since the tip of the retractor is relatively sharp, it cannot be hidden after entering the operating space, and it is easy to accidentally pierce other tissues, especially large blood vessels in the neck, increasing the risk during surgery;

[0006] 2. Fixed structural features: The arc and length of the retractor are too fixed. When pulling thicker, tighter or farther tissues, it is easy to slip or shift, affecting the smoothness of the surgical operation. Since its structure cannot be intelligently adjusted according to the thickness, direction or distance of different tissues, its applicability is significantly limited, especially in complex anatomical situations;

[0007] 3. Insufficient strength: The retractor adopts a slender stainless steel rod structure, which is easy to bend and deform under a large pulling force, reducing the reliability of the instrument and further affecting the life of the instrument and the surgical effect;

[0008] 4. Limited adjustment angle: The adjustment range after piercing the skin is limited, and the pulling angle is fixed, which cannot meet the needs of different surgeries. This design limits the flexibility and efficiency of the instrument during surgery, especially when the pulling direction needs to be adjusted to obtain a better view. Summary of the invention

The rectangular block 802 can only move in the direction close to or away from the pressure sensor 809 in the first sphere 801, and cannot rotate.

[0045] In this embodiment, the first pull rope 504 passes through the rectangular block 802 and extends into the hook head end 3 .

[0046] Further, as a preferred embodiment, an anti-skid pad is also included, and each clamping jaw 803 is provided with an anti-skid pad on one side facing the first sphere 801. The anti-skid pad is provided to facilitate contact with the outer wall of the first sphere 801 to prevent the first sphere 801 from rotating. When the angle of the hook head end 3 needs to be adjusted, the second knob 806 can be rotated so that the second winding wheel 808 releases the second pull rope 805. Here, the second knob 806 is rotated as needed, as long as the first sphere 801 can be rotated relative to the clamping jaw 803, the first sphere 801 can be prevented from escaping from the clamping area of ​​the clamping jaw 803, and then the hook tip 4 is pressed against the tissue, and the hook head end 3 is rotated with the point where the hook tip 4 contacts the tissue as a fulcrum to adjust the angle of the hook head end 3. After the angle adjustment is completed, the second knob 806 is rotated to tighten the second pull rope 805, so that the clamping jaw 803 clamps the first sphere 801 to fix the angle of the first sphere 801.

[0047] Further, as a preferred embodiment, a limiting hole is provided on the first sphere 801 , and one end of the hook head 3 passes through the limiting hole and is connected to the rectangular block 802 .

The positioning member 703 can be a bolt.

[0049] The tip of the retractor 4 in this embodiment can be received in the retractor head 3 to avoid accidental puncture of other tissues by the tip during the operation, thereby improving the safety of the operation. Through the arrangement of the bendable rod 6, the telescopic mechanism 7 and the angle adjustment mechanism 8, the intelligent adjustment of the arc, length and angle can be realized, and the adaptability and operational flexibility are significantly improved. The rod body 1 and the retractor head 3 are made of alloy materials, and the surface of the rod body 1 and the retractor head 3 is coated with an anti-fatigue coating, which can provide higher pulling strength and durability to meet the needs of complex operations. The retractor head 3 can be detached from the clamping area of ​​the clamping claw 803 to facilitate the replacement of the retractor head 3 of different shapes. For example, the selection of a flat surface, a wide hook type or a spiral shape can expand the pulling area and reduce the complexity of using multiple retractors. Through the cooperation of the pressure sensor 809 and the rectangular block 802, the pulling force on the tissue can be monitored in real time.
