Problems solved by technology

Due to the existence of individual differences, the plane P is different and it is difficult to fully estimate it before surgery. Once the cannula is placed in the traditional surgical method, it cannot be adjusted, and the relationship between L1 and P cannot be changed, which limits the operation in many cases.
2. The traditional cannula (such as Stryker's) is relatively long, more than 10cm, and the proximal end is enlarged with a device to prevent air leakage
Due to individual differences, the thickness of the abdominal wall cannot be predicted, so only a longer cannula can be used

Abstract

The invention relates to a laparoscope canula device, comprising a disk with a first surface and a second surface which are opposite to each other, a plurality of ball-like canulas which are arranged in the disk and enable the first surface and the second surface to be penetrated through, an elastic sealing skirt which is arranged along the outer diameter of the second surface and a plurality of supporting rod structures; and a first end of the supporting rod structure is articulated with the second surface, and a second end of the supporting rod structure is connected with the lower hem of the elastic sealing skirt. The laparoscope canula device is used for medical-treatment operations.

Description

【Technical field】 [0001] The invention relates to a laparoscopic cannula device, in particular to a laparoscopic cannula device used in single-hole laparoscopic surgery. 【Background technique】 [0002] In 1987, Mouret of France performed cholecystectomy under video laparoscopy, which marked the beginning of an epoch-making era of minimally invasive surgery in the history of surgery. [0003] First, we describe the technical background of this patent from the perspective of laparoscopic cholecystectomy. Currently, laparoscopic cholecystectomy (three or four holes) has become the gold standard for cholecystectomy. However, single-port laparoscopic cholecystectomy has been tried by some surgeons because it is more minimally invasive and has cosmetic effects. But it is more difficult. The reasons for the difficulty of single-port laparoscopic cholecystectomy are analyzed, including the factors of laparoscopic instruments. Generally, the operation method of laparoscopic singl...
