A retractor for thyroid surgery

Abstract

The invention discloses a retractor for thyroid surgery, which relates to the technical field of medical appliances. A retractor for thyroid surgery includes a first expansion plate, a second expansion plate and a widening mechanism, wherein one end of the second expansion plate is The connection assembly is movably connected with the first expansion plate to be away from or close to the first expansion plate; the widening mechanism includes a manual operation part, a transmission assembly and at least one expansion assembly, and the expansion assembly is slidably arranged between the first expansion plate and the second expansion plate. Between the two expansion plates, and the sliding direction is along the width direction of the first expansion plate, the manual operation part is connected to the expansion assembly through the transmission assembly to drive the expansion assembly to slide, and the manual operation part is located on the first expansion plate. The proximal end of the expansion plate, the expansion assembly is located at the distal end of the first expansion plate. The invention can open a larger space than the axillary incision at the place close to the patient's thyroid gland by expanding the widening mechanism, which is convenient for doctors to perform operations.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to a retractor for thyroid surgery. Background technique [0002] Thyroid surgery removes part or all of the thyroid gland on one side of the patient, and often preserves all or part of the thyroid tissue on the opposite side to maintain the required physiological functions. The traditional method of thyroid surgery is to make a small incision in the patient's neck to expose the thyroid gland, and then perform the operation, but after the operation, the patient's neck will have keloids, which will affect the appearance. With the development of medical technology, thyroid surgery can make a small incision in the patient's armpit, and then use an ordinary retractor to insert from the patient's surgical incision and extend into the patient's neck, and then use the retractor to pull up the patient's epidermal tissue, Provide certain operating space for doctors to perform thy...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, based on the principle of minimally invasiveness and minimal damage to the patient, the incision at the armpit will be as small as possible, so the passage from the incision to the thyroid gland must not be too large, because the height of the epidermal tissue is limited , the resulting surgical space is relatively narrow, and the field of view and operating space for the doctor to perform the operation are narrow, making it difficult for the doctor to perform thyroid surgery. Although the existing surgical retractors can open the incision and the channel to a certain extent, it is difficult to operate in the vicinity. The patient's thyroid gland requires a larger operating space than the axillary incision due to observation and resection, and the existing surgical retractors cannot meet the need for a larger space than the axillary incision near the patient's thyroid. more difficult
