Problems solved by technology

There are three disadvantages of this subcutaneous separation rod: 1. It can only cut straight forward, causing unnecessary damage to the tissue in the non-operative area, such as figure 2 As shown, the right slash is the area that can avoid injury; 2. Due to the existence of skin and attached subcutaneous fat tissue, it is difficult and time-consuming to connect each channel into a complete space; 3. The isolated The channel is narrow, the visual range is small, and the image is blurred

Abstract

The invention discloses a spatial dilator for endoscopic thyroidectomy. The spatial dilator comprises a sleeve, a push rod capable of telescoping along the axial direction is arranged in the sleeve, a button matched with the push rod and capable of pushing the push rod to telescope is arranged outside the sleeve, the left side of an extending end of the push rod is movably connected with one end of a left connecting rod blade, and the right side of the same is movably connected with a right connecting rod blade. The other ends of the left connecting rod blade and the right connecting rod blade are respectively connected with a left cutter and a right cutter which are movably connected with ends of the sleeve. The other end of the push rod is connected with a handle. By the spatial dilator for endoscopic thyroidectomy, hurt to breast skin of patients is reduced, operation is simplified, and operation time can be effectively shortened.

Description

[0001] technical field [0002] The invention relates to a medical instrument, which is a special space expander for endoscopic thyroid surgery. Background technique [0003] Thyroid disease is a common and frequently-occurring disease, especially in young women. Surgical treatment is one of the ultimate cures for this disease, and it is also the most commonly used and most effective method. Traditional open surgery needs to leave a surgical scar about 6-8cm long on the neck, which leaves a heavy psychological shadow on the patients and seriously affects their daily life, study and work. Laparoscopic thyroid surgery has completely changed this situation. While curing the disease, it can conceal the tiny wound and take into account the advantages of safe resection of thyroid lesions and beauty. It is currently being carried out more and more widely. [0004] In laparoscopic thyroid surgery, skin flap separation instruments are needed, and the existing subcutaneous separation...
