Description

Spleen ware is got in peritoneoscope special use

Technical Field

The utility model belongs to the technical field of surgical medical instruments, and particularly relates to a special spleen taking device for a laparoscope.

Background

Splenectomy, a common procedure for the treatment of portal hypertension, schistosomiasis, and hematological disorders, was first reported in 1992 and since then developed in succession in countries around the world; the European Endosurgery Association of 2008 indicates that laparoscopic splenectomy has become the standard procedure for most splenic benign and malignant diseases, and can almost replace laparotomy; although the guideline still lists the giant spleen and portal hypertension as contraindications, a great number of reports about the treatment of portal hypertension under laparoscope are available at home and abroad along with the development of laparoscope technology and various instruments; although the operation risk of the method is large and the technical difficulty is high, the laparoscopic operation is safe and feasible and the long-term curative effect is reliable as long as the operation adaptation syndrome is strictly mastered, the preoperative preparation is sufficient, the intraoperative detailed operation is carefully carried out and the abdomen is opened when the operation is interrupted;

the main steps of the splenectomy are to free the ligaments around the spleen and treat the splenic pedicle, and the spleen is fragile and soft, so that grasping forceps are forbidden, and the spleen can be lifted only by using a sucker and other rods to expose the ligaments around the spleen; however, the spleen surface is smooth, so that the spleen is difficult to lift and the front end of the rod is easy to puncture the spleen, so that bleeding is caused, and the operation process is influenced; particularly for patients with portal hypertension, the peripheral adhesion is serious, the spleen is large, and the operation is difficult by only using a pull rod; when the blood vessel of the spleen pedicle is treated, the closing spleen pedicle is often cut by ENDO-GIA (endoscopic cutting closer), at the moment, the ENDO-GIA needs to completely penetrate through the spleen pedicle, but the closing of the spleen pedicle is incomplete easily or the spleen is damaged due to the problem of visual field exposure to cause hemorrhage, therefore, when the spleen resection is carried out, ligaments around the free spleen and the spleen pedicle which need to be taken out are cut in the body under the guidance of a laparoscope, and the spleen fragments are taken out through small poking holes after being cut, and the blood water around the spleen fragments is difficult to clean in the process of taking the spleen fragments, so that the visual line is influenced, the taking efficiency is low, and the poking card does not have the cutting function, so that the spleen fragments which need to be taken out are difficult to be taken out if not cut through with other fragments in the process of taking the spleen fragments out, resulting in a problem of low extraction efficiency.
