Description

Inflatable adjustable anti-drop stabs card

Technical Field

The utility model relates to the technical field of instruments for endoscopic surgery, in particular to an inflatable adjustable anti-falling poking card.

Background

Laparoscopic surgery is a minimally invasive surgical method developed from laparoscopic surgery, and is a necessary trend for the development of future surgical methods. With the rapid progress of industrial manufacturing technology, the fusion of relevant disciplines lays a solid foundation for developing new technologies and new methods, and doctors are increasingly skilled to operate, so that many past open operations are replaced by intracavity operations.

In endoscopic surgery, in order to make an elongated surgical instrument enter a cavity through a surgical access, a special channel is mainly established by a poking card, and then the elongated surgical instruments such as forceps, an electric hook, an ultrasonic knife and the like enter the cavity through the poking card so as to perform surgical operation of cutting a focus. In the process of establishing a special channel by the existing stamping card, one end of the stamping card is inserted into human tissue (skin), and the other end of the stamping card is positioned outside the human tissue (skin). The utility model publication No. 201820834085.7 discloses an anti-leakage and anti-falling poking card, which comprises a poking card main body and a poking card pipe which are arranged in a whole, an air bag and an air inlet pipe for inflating the air bag; the middle part of the outer wall of the poking clamp pipe is of a concave pipe section structure; the air bag is sleeved on the inner concave pipe section and can slide up and down along the axis of the poking clamping pipe; the middle pipe section of the air inlet pipe is attached to the poking card Guan Nabi, the air outlet end of the air inlet pipe is connected with the air bag, and the air inlet end of the air inlet pipe is exposed out of the poking card. The position of the air bag in the human tissue is adjusted, so that the air bag is tightly attached to the inner layer of the human tissue, and the problems of air leakage and subcutaneous emphysema formation in operation caused by the increase of the split of the human tissue (skin) when the poking position is repeatedly corrected to maintain the operation can be solved. In this prior art utility model, there are problems in that: 1. the elastic member (rubber ring) is adopted to limit the positions of the human tissue layer and the air bag, the rubber ring moves on the poking and clamping tube by hands, but in order to limit the positions of the human tissue layer and the air bag better, the friction force between the rubber ring and the poking and clamping tube is necessarily large, and the rubber ring is very inconvenient to move; if the friction force between the rubber ring and the poking pipe is not large, the rubber ring can slide easily on the poking pipe, and the rubber ring can slide after the air bag is inflated, so that the set position of the rubber ring is changed, the position of the adjusting air bag in human tissues is changed, and the follow-up operation is inconvenient; 2. the smoke gas in the poking card can influence the field of vision of doctors in the operation process, so that the problem of the need of matching the poking card is solved.

Therefore, there is a need to develop an inflatable adjustable anti-drop stab card to solve the above problems.
