Embodiment 1

[0026] Example 1: A new type of drainage device (see attached image 3 Attached Figure 4 ), including a drainage tube 3 made of silicone material and a thimble 8 that can be inserted into the drainage tube. The outer diameter of the drainage tube body is larger than the inner diameter of the drainage channel, and the end of the drainage tube is provided with a diameter larger than the outer diameter of the drainage tube body The head 6, the inner wall of the end of the circular hole at the head is provided with four baffle strips 7, which are evenly arranged on the inner wall of the circular hole 5 at the head, the end of the head is spherical, and the head and drainage There is a smooth transition between the tube bodies, the wall thickness at the head is greater than the wall thickness of the drainage tube body, the diameter of the thimble is larger than the diameter enclosed by the inner side of the stop bar, and the tail section of the thimble is provided with three parallel...

Embodiment 2

[0027] Example 2: A new type of drainage device (see attached image 3 Attached Figure 5 ), including a flexible drainage tube 3 with a through-hole inside and a thimble 8 that can be inserted into the drainage tube. The drainage tube is made of silicone material. The outer diameter of the drainage tube body is larger than the inner diameter of the drainage channel. The end of the drainage tube There is a head 6 with a diameter larger than the outer diameter of the drainage tube body. The inner wall of the end of the circular hole at the head is provided with four barrier strips 7 which are evenly arranged on the inner wall of the circular hole 6 at the head. The end is spherical, and there is a smooth transition between the head and the drainage tube body. The wall thickness at the head is greater than the wall thickness of the drainage tube body. The diameter of the thimble is larger than the diameter enclosed by the inner side of the barrier. The end is provided with a threa...

Abstract

The invention relates to a novel retractable drainage device capable of realizing hemostasis by compression and an application method thereof, which solve the problem that no appropriate drainage tube is available to drainage and hemostasis after percutaneous nephroscope operation in the prior art. The outer diameter of a drainage tube body is larger than the inner diameter of a drainage channel,the end part of the drainage tube is provided with a seal end of which the diameter is larger than the outer diameter of the drainage tube body, and the inner wall at the end part of a round hole at the seal end is provided with a plurality of blocking strips. The novel drainage device further comprises a centre which can be penetrated into the drainage tube body, wherein the diameter of the centre is larger than the diameter defined by the inner sides of the blocking strips and is smaller than the inner diameter of the drainage tube. By arranging the seal end with the larger diameter at the end part of the drainage tube, the drainage tube can be conveniently placed into the drainage channel by lengthening the drainage tube to reduce the diameter of the drainage tube body before reducing the diameter of the seal end at the end part of the drainage tube, and a wound can be compressed by the seal end to realize hemostasis after the drainage tube is released. Besides, the novel drainage device is convenient to operate and simple in structure, and enables patients not to suffer from sagging distention.

Description

Technical field [0001] The invention relates to a medical appliance, in particular to a novel drainage device which can be stretched and compressed to stop bleeding and a method of use. Background technique [0002] Minimally invasive percutaneous nephroscope technology is an emerging stone treatment technology developed on the basis of the original classic percutaneous nephroscope. It narrows the kidney puncture expansion channel and uses ureteroscope-assisted pneumatic ballistic lithotripsy or holmium laser. The technology for the treatment of kidney stones has the advantages of high safety, less bleeding, and less trauma, and has been rapidly promoted since its invention. The drainage tube of the minimally invasive percutaneous nephroscope dilation and drainage surgical instrument uses a traditional latex drainage tube, which cannot be fixed by itself. It usually needs to be externally fixed outside the skin, and the histocompatibility is poor, and the local inflammation is re...
