Liver poking equipment for laparoscopic gastrointestinal surgeries and use method of liver poking equipment

Abstract

The invention relates to the technical field of laparoscopic gastrointestinal surgeries and discloses liver poking equipment for laparoscopic gastrointestinal surgeries and a use method of the liver poking equipment. The liver poking equipment comprises a holding part; a limiting column is fixedly connected to the groove wall of a through groove; a movable plate is connected to the column arm of the limiting column in a sleeved mode, and slidably connected into the through groove; a sleeving piece is fixedly connected to the upper end of the limiting column; the end, away from the limiting column, of the sleeving piece is connected with the movable plate; a driving mechanism of which the speed is gradually reduced when being used for driving the movable plate to move towards the sleeving piece is arranged in the through groove; and a first key set used for controlling the driving mechanism is arranged on the outer wall of the holding part. The device has the effects that the sleeving piece can be automatically controlled to stretch out or retract in by pressing the key set, and in the stretching-out process of the sleeving piece, the speed of increasing a sleeving space formed after the sleeving piece stretches out is gradually decreased, so that an operator can conveniently judge whether the size of the sleeving space of the sleeving piece in change is suitable for the size ofa current liver or not in time.

Description

Technical field [0001] The invention relates to the technical field of laparoscopic gastrointestinal surgery, in particular to a liver plucking device for laparoscopic gastrointestinal surgery and a method of use thereof. Background technique [0002] Liver diseases are common diseases in general surgery, including hepatolithiasis, hemangioma, liver cancer, etc. Most of them require surgical treatment. During the operation, doctors often need to use instruments to stretch and expose the liver, so as to obtain a clear surgical field of vision, and can Manipulate other surgical tools within the area. [0003] For example, the cited document Chinese patent CN201910369704.9 discloses a retractor for laparoscopic liver surgery. Publication date: 20190709. The invention includes an outer tube, the two ends of the outer tube are penetrated, and the push rod is arranged in the outer tube. And the push rod can be extended and contracted in the outer tube, and the pull piece, the pull piece...

AI Technical Summary

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
