Retractor and retractor fixing device

Abstract

The invention aims to provide an endoscopic surgery retractor better in muscle retraction cavity-building effect and convenient for smoke suction and wound cleaning. The retractor comprises a retractor body and a catheter, the retractor body is composed of a supporting plate, a connecting plate and a fixing plate, axis of the supporting plate is arranged in front-rear direction, the fixing plate is positioned on the upper side of the supporting plate, the connecting plate is positioned between the rear end of the fixing plate and that of the supporting plate to enable the retractor body to beU-shaped, a matching hole which is longitudinally through is formed in the front end of the fixing plate, a retraction plate is arranged on the front side of the supporting plate, the retraction plateand the supporting plate are arranged obliquely, and the retraction plate extends leftwards or rightwards from rear to front; the catheter at least comprise a first catheter section fixed on the lower side of the supporting plate, and the front end of the first catheter section extends to the lower side of the retraction plate. The invention aims to further provide a retractor fixing device freely adjustable in fixing position of the retractor.

Description

technical field [0001] The invention relates to a medical operation instrument, in particular to a retractor for laparoscopic surgery and a retractor fixing device for fixing the retractor. Background technique [0002] In recent years, the incidence of thyroid cancer has increased rapidly. Traditional surgical methods will leave a scar of about 5 cm on the front of the neck, which seriously affects the appearance. With the development of endoscopic surgical techniques, thyroid surgery has ushered in a new era: completely endoscopic thyroid surgery. At present, although endoscopic thyroid surgery has been widely carried out across the country, most of them are chest and breast surgery (with a small incision on both areolas and chest) endoscopic thyroid surgery. Visible scarring. [0003] The inventor took the lead in carrying out "Complete endoscopic thyroid surgery without inflatable axillary approach" in China last year. This operation skillfully changes the surgical in...

Problems solved by technology

The existing thyroid puller (retractor) is also called a right-angle retractor. It is flat hook-shaped and has a plate. Both ends of the plate extend to one side and are bent to form a hook. This kind of retractor is commonly used It can be used to pull and expose the thyroid gland, and can also be used for other operations, such as retracting the skin, subcutaneous tissue, muscle and fascia, etc.; but this retractor is not suitable for completely laparoscopic thyroid surgery without inflatable axillary approach , the cavity building effect of this retractor is very poor, and it is difficult to provoke the sternohyoid and sternothyroid muscles

[0005] After the cavity is built with the retractor, the tumor needs to be cut with the ultrasonic knife, which will generate a lot of smoke during the operation of the ultrasonic knife, and the incision wound needs to be cleaned before the cavity is built. Difficult to remove the smoke and clean the wound after the cavity

[0006] The retractor fixing device usually includes a hook body, and the retractor has an upward force through the hook body, but the setting of the existing retractor fixing device is very troublesome, and the height position of the hook body cannot be adjusted. Difficulty applying retractors to procedures on patients of all sizes
