Embodiment Construction

[0016] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0017] As shown in FIG. 1 , the water injection needle body 1 is bent into a blunt tubular shape, with a blunt blind end 11 at the front end, and a water outlet hole 12 on the opposite side walls adjacent to the blind end 11 . The rear end of the water injection needle body 1 is a water inlet 13 . In order to facilitate connection with a syringe barrel (not shown in the figure), the shape of the water inlet 13 is designed to be the shape of a standard syringe barrel joint. The front side of the water inlet 13 is a valve 2, which is used to prevent the expansion fluid from flowing backwards.

[0018] During the operation, after making a small incision of the observation hole in front of the sternum, the front end of the water injection needle is inserted obliquely into the area to be separated to reach the superficial layer of the deep fasci...

Abstract

This invention discloses a subsurface injection acus for scope thyroid operation, whose structure is: acus body is tubular shaped; and its front end is a blunt-pointed dead end, whose neighboring sidewall has no less than one delivery orifice; its tail is a inlet orifice, whose front side has a valve. This subsurface injection acus is one of applicable and valid surgical instruments that used to build subsurface channel. It has simple structure and is easy to handle. It can effectively heighten operation safety and shorten operation period.

Description

technical field [0001] The invention relates to a medical device, in particular to a hypodermic water injection needle specially used for laparoscopic thyroid surgery, which is applied to create subcutaneous space in 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 surge...
