Description

Special opener equipment for thyroid

Technical Field

The invention relates to a thyroid surgery instrument, in particular to a special thyroid dilator device.

Background

The thyroid operation mainly refers to a thyroidectomy operation, and the majority of the thyroidectomy is an effective means for treating simple goiter, hyperthyroidism, thyroid cyst and the like. In the process of performing the thyroid gland excision operation, a wound for operation needs to be cut at the skin of the thyroid gland position of a patient to meet the requirement of the thyroid gland excision, so that a long scar can be left at the neck position of the patient after the operation, and some patients have the beauty requirement and are not satisfied with the scar residue. At present, an endoscopic thyroid surgery method exists, which is used for amplifying and displaying a surgery visual field by means of a high-definition imaging system so as to assist surgery, and has various paths such as a full-mammary areola approach, a breast milk approach, a peroral approach and a subclavian approach, and endoscopic thyroid surgery which is popular in recent years and is accessed through armpits, and the like.

Meanwhile, when the thyroid resection operation is performed, an operation space needs to be established at the thyroid position, so that the thyroid resection operation is convenient. Currently, the inflation method is a common thyroid surgery space maintaining technology, which is used for maintaining enough surgery operation space by filling carbon dioxide gas after skin flap separation, but the method can generate respiratory acidosis or hypercapnia, and can affect jugular vein reflux, so that intracranial pressure is increased. In order to solve the above problem, there is a suspension expanding method for maintaining an operation space, which uses different suspension articles, such as silk threads or skin forceps, but the basic principle is to use a structure to puncture and fix the skin, and pull the operation position in vitro. It is conceivable that this technique is used for inflation-free distraction in current endoscopic thyroid surgery, and has a certain expected effect. However, the inventor finds that the technology still has a plurality of problems in practical implementation, for example, the suspension structure needs to be fixed with the skin, the skin is damaged in a generally adopted mode, the stress surface is small, the damage is easily caused in the suspension process, and the stability of the operation space is poor.
