Sella bottom hole blocking device

Abstract

The invention discloses a plugging device for an orifice at the bottom of a sella. The plugging device comprises a stopper, a pipe used for conveying the stopper and a push rod used for pushing the stopper. The stopper consists of two spring umbrellas with two centers connected. The spring umbrella consists of a plurality of spring strip ribs and a thin film. A plurality of spring strip ribs intersect at a point and are fixed on the round or ellipse thin film. The pushing rod is arranged in the chamber of a pipe and the diameter of the pushing rod is smaller than the inner diameter of the pipe. For neurosurgery, the operation only can be carried out by penetrating the bottom of the sella by a sphenoid bone, and consequently, an operation wound is left on the sphenoid bone. The invention is designed to solve the problem that the operation wound left on the sphenoid bone is difficult to be plugged and repaired. In the plugging device provided by the invention, the stopper consisting of two spring umbrellas is plugged into the front end of the push rod in the pipe; the stopper is conveyed to position of the operation trauma through the pipe; the stopper is pushed out by the push rod slowly; and the two spring umbrellas are opened one after another and clamp the edge of the wound to close the wound. The plugging device for the orifice at the bottom of the sella has simple structure, easy operation and reliable effect.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a medical device for closing the surgical wound of the saddle floor. Background technique [0002] In neurosurgery, it is often necessary to go through the sella floor through the nasal sphenoid. After surgery, a surgical hole is left in the sellar floor sphenoid bone. If it is not closed, the cranial cavity can communicate with the outside world through this wound, and there are hidden dangers of cerebrospinal fluid leakage and infection with bacteria and viruses. There is no easy and reliable sealing method so far. Contents of the invention [0003] The purpose of the present invention is to provide a kind of device with simple structure, convenient operation and reliable effect for the operation wound hole of the bottom of the saddle. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] A saddle bottom orific...

Problems solved by technology

[0002] In neurosurgery, it is often necessary to pass through the sphenoid sella through the sphenoid for surgery. After surgery, there is a surgical wound in the sphenoid bone of the sella bottom. If it is not sealed, the cranial cavity will communicate with the outside world through this wound, and there will be hidden dangers of cerebrospinal fluid leakage and infection of bacteria and viruses.
