Specimen holding device for right hemicolon NOSES surgery and application method thereof

Abstract

The invention provides a specimen holding device for right hemicolon NOSES surgery and an application method thereof. The holding device includes a device body made of a soft material; the device bodyis in a penetrating cylindrical structure, and the length of the device body matches the length of a specimen; along the axis direction of the device body, the device body is provided with multiple tightening ropes, and the multiple tightening ropes can be slidingly surrounded on the device body relative to the device body; and each tightening rope is fixed at the relative position of the devicebody. An application method of the holding device is also disclosed. Thus, through the holding device, the successful taking out of a right hemicolon specimen can be achieved, and the damage to intestinal mucosa can be reduced; and the bacterial infection of the specimen and the accidental shedding of tumor cells can be effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a specimen holding device for right colon NOSES operation and a method for using the same. Background technique [0002] As a rookie in minimally invasive surgery, natural orifice specimen extraction (NOSES) not only shows a perfect minimally invasive effect, but also takes into account good safety and operability. At present, the specimen holding device for NOSES surgery is mainly designed for rectal resection specimens, and there are few protective sleeves for colectomy specimens, and there is no special specimen holding device for taking out right colon NOSES surgery specimens through the colon, rectum, and anus. [0003] If there is no protection of the specimen holding device, the right colon specimen is directly taken out through the colon, rectum, and anus, which does not follow the principle of sterility and tumor-free, and the specimen is easily dam...

AI Technical Summary

Problems solved by technology

[0003] If there is no protection of the specimen holding device, the right colon specimen is directly taken out through the colon, rectum, and anus, which does not follow the principle of sterility and tumor-free, and the specimen is easy to be damaged during the taking out process, and the integrity of the specimen cannot be guaranteed

The specimens of right hemicolectomy are longer than those of rectal resection. After resection, the specimens need to travel a long distance in the intestinal tube during the removal process, and need to pass through the spleen region of the colon, the junction of the descending colon and the sigmoid colon, and the junction of the sigmoid colon and the rectum. At the same time, the sigmoid colon It is curved in the shape of "B" in the human body, and the arc is large. The existing specimen collection device cannot pass through these three bends smoothly, and it is easy to cause damage to the intestinal mucosa or even tear the intestinal tube, resulting in the failure of the operation; and the flow of the specimen out of the intestinal tract , resulting in intestinal colonization of tumor cells

At the same time, due to the large size of the specimen itself, there is a risk of being dragged out in the process of dragging the specimen, which is likely to cause damage to the intestinal tissue and affect the normal function of the anus after surgery.
