Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a gallbladder puncture and drainage device. Background Art

[0002] The gallbladder is located in a pear-shaped sac structure behind the liver under the right ribs (in the gallbladder fossa of the liver). It has the function of concentrating and storing bile. The gallbladder is divided into four parts: the base, body, neck, and tube. The neck is connected to the cystic duct. The gallbladder wall is composed of three layers: mucosa, muscular layer, and outer membrane. Percutaneous transhepatic gallbladder puncture and drainage is a minimally invasive surgical treatment method, mainly used for patients who are not suitable for emergency cholecystectomy. After the puncture is completed, the drainage tube is left in place for a long time, and there is a risk of the tube falling off;

[0003] In this regard, the Chinese utility model patent with the authorization announcement number CN216535459U discloses a gallbladder puncture drainage tube that is anti-drop and anti-blocking, including a puncture tube, wherein a first opening is provided at the top of the puncture tube, and a plurality of second openings are provided around the side of the end of the puncture tube; at least two third openings are provided around one side of the second opening, wherein one end of the third opening is a first blocking portion; a blocking mechanism is installed in the third opening, wherein one end of the blocking mechanism is provided with a second blocking portion that matches the shape of the first blocking portion; one end of the blocking mechanism is connected to a traction mechanism through a connecting portion, but this anti-dropping method has the following defects:

[0004] The above-mentioned method adopts a blocking mechanism to prevent the drainage tube from falling off by setting a blocking mechanism on the outside of the end of the drainage tube. There is also a similar method of using an air bag. Since the drainage tube itself has a small diameter and a thin tube wall, the use of this structure is bound to increase the thickness of the drainage tube at this position, resulting in an increase in the diameter of this position. This is likely to cause damage to human tissue during puncture, which is not practical enough. There is also a method of fixing the drainage tube by pulling a wire, that is, a wire fixed to the end is provided in the drainage tube. After the puncture is completed, the wire is pulled, and the end of the drainage tube is forced to form a curled shape, forming a limit to prevent falling off. However, it has high requirements for medical personnel. If the wire is pulled too loose, the curling degree is too low, and it will still fall off. If the wire is pulled too tight, it is easy to cause the drainage tube channel to be blocked, which is more troublesome to operate.

[0005] Therefore, we propose a gallbladder puncture drainage device to solve the above problems. Utility Model Content
