[0002] The mammary gland and the thyroid gland are two organs of the human body. One is the mammary gland, and the other is the thyroid gland. The mammary gland is the human breast and also an organ for lactation, while the thyroid gland is an organ in the neck that mainly secretes human thyroxine and is also closely related to human growth. In the resection surgery of the mammary gland and the thyroid gland, it is necessary to first separate the mammary gland and the thyroid gland from the tissues and pull up the lesion site before the surgery can be carried out.

[0003] The prior art CN218589053U discloses a clinical retractor assembly for the mammary gland and the thyroid gland, which includes an adjustment assembly and a hook assembly arranged at both ends of an assembly tube. A fixing block is arranged on the inner side of the tail of the assembly tube, and a through mating hole is arranged on the side of the fixing block. The adjustment assembly includes: a rotating block meshingly connected to the tail end of the assembly tube, a pulling rope fixedly arranged on the side of the rotating block, and the pulling rope passes through the mating hole to connect the hook assembly; the hook assembly includes: a hinge frame arranged at the front end of the assembly tube, one end of the hinge frame is rotatably connected to a rotating shaft, a connecting block is arranged in the middle of the rotating shaft, one end of the pulling rope is fixedly connected to the side of the connecting block, and a retractor is integrally arranged on the outer peripheral side of the rotating shaft. This device is not convenient for disassembling and assembling the retractor after the operation, is not conducive to thoroughly cleaning and disinfecting the retractor after the operation, reduces the surgical efficiency, and greatly reduces the practicability.
