Embodiment Construction

[0023] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] The present invention provides a puncture positioning guide, see figure 1 , including coaxial and separated first guide tube 1 and second guide tube 3, one end of the first guide tube 1 away from the second guide tube 3 is connected with a first connecting tube 2, and the other end of the first connecting tube 2 passes through The second connecting rod 4 is connected to the second guide tube 3, the lumen of the first guide tube 1 and the first connecting tube 2 is a guiding passage for passing through the guide wire, and the first connecting tube 2 is also opened. There is a lead-out hole 5 for the guide wire to pass through, and the second guide tube 3 is a hollow semicircular tube with an upward opening, and its upper opening space is a guide passage for the trocar core to pass through. Along the coaxial guide channel formed by the ...

Abstract

The invention discloses a puncture positioning guider, a puncture positioning device and using methods thereof. The puncture positioning guider comprises a first guide tube and a second guide tube which are coaxially and separately arranged, wherein a first connecting tube is connected to one end, away from the second guide tube, of the first guide tube, and the other end of the first connecting tube is connected to the second guide tube via a second connecting rod; a guide passage used for allowing passing of a guide wire runs through inner cavities of the first guide tube and the first connecting tube; a guide outlet hole allowing penetrating-out of the guide wire is formed in the first connecting tube; the second guide tube is a hollow semicircular tube with an upward opening, and an upper opening space thereof is a guide passage allowing passing of a core of a puncture device. The problem that there is no proper instrument for performing subcostal clearance separation and guidance in a subcostal anterior mediastinum surgery via a novel endoscope is solved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to a puncture positioning guide, a puncture positioning device 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 the potential tissu...
