Problems solved by technology

Johnson & Johnson’s subcutaneous separation stick is made of plastic, 40cm long, 1cm in diameter, and has a conical front end, which is relatively sharp. During the separation process, it is easy to damage the subcutaneous blood vessels and muscle layer, causing subcutaneous bleeding, blurring the operative field, and prolonging the operation time. Its plastic design makes the product lightweight and difficult to handle, increasing the chance of damage to the skin and surrounding tissue

Embodiment Construction

[0014] As shown in Figures 1 and 2, the subcutaneous separation rod is formed by fixedly connecting the separation rod body 1 and the handle 2, the separation rod body 1 is made of stainless steel, and the handle can be made of plastic. The front section of the separation rod body 1 is a partial spindle body 11 with two ends thin and the middle thick. The largest width a in the middle of the spindle body 11 is about 1.2-1.8 times the thickness b.

[0015] As a preferred solution, the maximum width a of the spindle body is 0.8-1.2 cm, and the length of the spindle body is 3.5-4.5 cm; the rear section of the separation rod body is a cylinder with a diameter of 4-6 mm and a length of 30-35 cm; the length of the handle is 6 ~ 8cm.

[0016] During the operation, the operator controls the handle with his hand, the front end of the separation rod enters the operation site from the operation hole, and the end of the spindle body performs subcutaneous separation from bottom to top. D...

Abstract

This invention discloses a subsurface segregation rod for scope thyroid operation, which is made by binding handle and segregation rod body. The front end of the body is a spindle, whose two ends are slender and the midst is thick. Because the forepart of the subsurface segregation rod is a leaning spindle-shaped, it will not injury skin, muscle and blood vessel facilely; the middle-part width of spindle is quite big, so the once segregation zone is large, this can shorten operation period; it is a metal devise and is very weightily, so it can be handled easily and continuously force, and it can avoid sudden damage for loss of manual control. This invention has simple structure and is easy to process, and its manufacturing cost is low.

Description

technical field [0001] The invention relates to a medical device, in particular to a subcutaneous separation rod specially used for laparoscopic thyroid surgery. Background technique [0002] 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 tiny wounds and take into account the advantages of safe resection of thyroid lesions and beauty. It is being carried out more and more widely. [0003] In laparoscopic thyroid surgery, the main key technologies include creating a subcutaneous channel to reach the su...
