Description

Retractor Devices for Pelvic Surgery

technical field

The utility model relates to a retractor device, in particular to a retractor device for pelvic surgery, which belongs to the technical field of medical device design and manufacture.

Background technique

In pelvic surgery, especially in low rectal and deep pelvic surgery, the pelvic cavity must be exposed by a special person to pull the hook all the way, and adjust it according to different operations and angles.

This retractor used in pelvic surgery has been involved abroad, and there are a large number of patents and documents. Since the 1930s, research and experiments on retractors have been conducted. But most of them are aimed at abdominal retractors, and there have been many automatic retractors with different functions applied in different operations. Foreign research on pelvic retractors is also far ahead of China. In 2000, an American named Robert F. Leonard applied for a patent for a pelvic retractor. The pelvic retractor he invented can already change the angle. .

After consulting the data, there is no automatic adjustable drag hook in China, and there are few improvements in the drag hook. For example, in laparoscopic appendectomy, the surgery uses needle retractors instead of the curved retractors commonly used today.

But there are no special changes except the improvement on the hook. This improvement was published in Huaxia Medicine in 2007 by doctors such as Wang Yuncheng from Baise People's Hospital in Guangxi. The article number is 1008-2409200704-0729-02. After the improvement, the surgical wound is smaller. However, it is not suitable for pelvic surgery when the field of view needs to be enlarged, so it is not used. In addition, there is no related article research on the same subject as this one.

When performing pelvic surgery clinically, whether abroad or at home, the pelvic floor tissue is generally pulled to both sides with traditional human retractors to expose the surgical field of view. Pull in multiple directions. There is no fixed bow frame at the back end of the traditional pelvic retractor. When the pelvic organ tissue affects the surgical field of view, more assistants are needed to assist in pulling it apart, which not only affects the operation space, but also consumes manpower. At the same time, the length and direction of traditional pelvic retractors cannot be adjusted. When it is necessary to adjust the force and angle during the operation, more manpower is required.
