Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 4, the present invention provides a technical solution: a thorax puncture outfit comprises a handle 1, a guide tube 2, a blade 3, a fixing bolt 4 and a baffle 5; the handle 1 is of a cylindrical structure, and one end of the handle is connected with the guide tube 2 through threads; the blade 3 is slidably mounted in the handle 1, and a slide way matched with the blade 3 is arranged in the handle 1; the peripheral wall of the handle 1 is provided with a window 6 along the axial direction; the fixing bolt 4 passes through the window 6 and the blade 3 to be connected with the blocking piece 5 so as to fix the blade 3.

A pointed end 7 is arranged on one side of the end part of the guide tube 2, and the pointed end 7 and the peripheral wall of the guide tube 2 are in arc transition 8; the cross section of the guide tube 2 is in the shape of an open ring, and the opening faces the pointed head 7.

The end part of the guide tube 2 is in a bullet shape when viewed from the normal direction of the opening, so that the lung is not easy to be damaged when the guide tube 2 is inserted into the thoracic cavity, and the insertion direction of the drainage tube after entering the thoracic cavity is adjusted.

The length of the guide tube 2 is 15cm, the outer diameter is 7mm, and the inner diameter is 6.5 mm.

The included angle between the connection of the two ends of the arc transition 8 and the axis of the guide tube 2 is 30 degrees.

The anti-skid grains 9 are arranged on the outer peripheral wall of one end, close to the guide tube 2, of the handle 1, so that a user can rotate the handle 1 conveniently, and the guide tube 2 and the handle 1 can be separated.
