Split-type positioning guide for minimally invasive surgery of anterior mediastinum and method of use thereof

Abstract

The invention discloses a split type positioning guider for an anterior mediastinum minimally-invasive surgery. The guider comprises a first positioning frame and a second positioning frame which are correspondingly connected, wherein the first positioning frame comprises a first connection rod, two ends of the first connection rod are connected with a first guide part and a second positioning part respectively, and the first guide part and the second positioning part are located on the same side of the first connection rod and are parallel with each other; the second positioning frame comprises a second connection rod, two ends of the second connection rod are connected with a second guide part and a second positioning part respectively, and the second guide part and the second positioning part are located on the same side of the second connection rod and parallel with each other. The invention further provides a use method. By means of the split type positioning guider and the use method, the problems that proper instruments for separation and guide in gaps below the xiphoid are unavailable in an anterior mediastinum surgery and pleura rapture is caused due to the fact that plier heads are too sharp or excessively short or cannot be accurately positioned are solved.

Description

technical field [0001] The patent of the invention belongs to the technical field of medical devices, and relates to a split-type positioning guide for minimally invasive surgery of the anterior mediastinum and its application method. Background technique [0002] At present, in the operation process of the new laparoscopic subxiphoid retrosternal mediastinal mass resection, since the operation is performed in the anterior mediastinum outside the retrosternal pleural cavity, a special tool is often required during the operation. The purpose of dissociation to the lower side of the bilateral costal arch incision through the subxiphoid incision is also required to avoid damage to the bilateral pleura, especially the right pleura. Blunt dissection with fingers often has insufficient length, coupled with the anatomical particularity of the reflexed part of the human pleura, it has the following fatal flaws, making it impossible to apply this new type of anterior mediastinal mini...
