Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] The present invention provides an integrated xiphoid-process costal margin directional positioning guide, see figure 1 , including coaxial and separated first guide tube 1 and second guide tube 3, fixedly connected between the first guide tube 1 and the second guide tube 3 by connecting rod 2; the first guide tube 1 is a tubular structure with a cylindrical cavity inside, the second guide tube 3 is a hollow semicircular tube with an upward opening, and the cylindrical cavity and the hollow semicircular tube form a guide channel for the trocar to penetrate. Along the guide channel formed by the first guide tube 1 and the second guide tube 3 , the puncture device can be precisely oriented to penetrate the human body, and the puncture head of the puncture device can pass through the opening 4 .

[0022] The outer wall of the first guide ...

Abstract

The invention discloses an integrated xiphoid costal margin lower orientating and positioning guider and a using method thereof. The integrated xiphoid costal margin lower orientating and positioning guider comprises a first guiding pipe and a second guiding pipe which are arranged in a coaxial and separated mode, and the first guiding pipe and the second guiding pipe are fixedly connected through a connecting rod; the first guiding pipe is of a pipe-shaped structure of which the interior is provided with a cylindrical cavity in a communicated mode, a hollow semicircular pipe with an upward opening is adopted as the second guiding pipe, and a guiding channel allowing a puncturing device to penetrate into is formed in the cylindrical cavity and the hollow semicircular pipe. Accordingly, the problem that in a xiphoid lower anterior mediastinum operation through a novel endoscope, no appropriate instrument for xiphoid lower gap separating and guiding exists is solved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to an integrated xiphoid-process subcostal-margin directional positioning guide and a use method thereof. Background technique [0002] At present, in the operation process of the new laparoscopic anterior mediastinal mass resection under the xiphoid process, since the operation is performed in the anterior mediastinum outside the retrosternal pleural cavity, a tool with a special angle is often required during the operation. The potential tissue gap between the chest wall, diaphragm, and pleura can be dissociated to the bilateral costal arch incision through the subxiphoid incision, and at the same time, the purpose of avoiding bilateral pleura, especially the right pleura, can be avoided. Using blunt finger separation often has insufficient finger length, which cannot fully meet the design requirements of the surgical incision. In addition, the anatomical particularity of th...
