Liver pulling device for laparoscopic gastrointestinal surgery and method of use thereof

Abstract

The invention discloses a liver-pulling device for laparoscopic gastrointestinal surgery and a method of use thereof, and relates to the technical field of laparoscopic gastrointestinal surgery, including a holding part, a groove wall of a through groove fixedly connected with a limiting column, and a limiting column The column arm of the column is sleeved with a moving plate, and the moving plate is slidably connected in the groove of the through groove. There is a driving mechanism inside which is used to drive the moving plate to move towards the pick-up direction, and the speed gradually decreases. The outer wall of the holding part is provided with a button group 1 for controlling the driving mechanism. The invention has the ability to automatically control the extension or retraction of the sleeve by pressing the button group, and during the extension process of the sleeve, the speed at which the sleeve space becomes larger after the sleeve is extended gradually changes. It is small, so that it is convenient for the operator to judge in time whether the size of the taking space of the changing taking part is suitable for the effect of the current liver size.

Description

technical field [0001] The invention relates to the technical field of laparoscopic gastrointestinal surgery, in particular to a liver pulling device for laparoscopic gastrointestinal surgery and a method of use thereof. Background technique [0002] Liver disease is a common disease in general surgery, including hepatolithiasis, hemangioma, and liver cancer. Manipulate other surgical tools in the area. [0003] For example, a retractor for laparoscopic liver surgery disclosed in the cited document Chinese patent CN201910369704.9, publication date: 20190709, the invention includes an outer tube, the two ends of the outer tube are connected, and a push rod is arranged in the outer tube. And the push rod can expand and contract in the outer tube, and the pulling member, the pulling member is arranged on the push rod, wherein, the push rod and the pulling member form an accommodating space, the accommodating space is a closed ring, and the accommodating space can be It acts o...

Problems solved by technology

[0005] The object of the present invention is to provide a liver pulling device for laparoscopic gastrointestinal surgery and its use method, which can automatically control the extension or retraction of the sleeve by pressing the button group, and the sleeve is in the During the stretching process, the speed at which the trapping space becomes larger after the trapping part is stretched out gradually decreases, so that it is convenient for the operator to judge in time whether the size of the trapping space of the changing trapping part is suitable for the current liver size, and solve the problem. In order to realize the adjustment of the space size of the pulling part by pushing and pulling the push rod manually, on the one hand, it is time-consuming and laborious to adjust by manpower. The rate of change is difficult to keep stable, and it is necessary to push and pull the push rod repeatedly to make the pulling space of the pulling member adapt to the current liver size
