Description

a puncture drainage tube

technical field

The utility model belongs to the field of medical equipment, in particular to a puncture drainage tube.

Background technique

When the patient does not need surgery and only needs to drain the fluid in the body, a puncture drainage tube is needed. The puncture drainage tube currently used is a rigid straight tube, and the puncture direction is single and limited. However, many puncture operations in clinical work need to be avoided. Internal organs and blood vessels are opened, so many current operations cannot be completed, and follow-up diagnosis and treatment cannot be implemented, and can only be converted into more traumatic operations. Secondly, when puncture drainage is performed with a CT machine, the length of the drainage tube currently used is fixed and cannot be stretched. If the drainage tube is too long, it is limited by the scanning aperture of the CT machine and cannot be performed. If the length of the drainage tube is too short, it cannot be placed in the ideal position. The purpose of diversion cannot be achieved. Another problem is that the currently used puncture drainage tube cannot flush and drain at the same time, which greatly reduces the puncture effect. In addition, the puncture operation can also be used to extract fluid from the patient's body for the diagnosis of difficult and complex diseases.

The rotation of the knob is converted into the rotation of the first bevel gear parallel to the axis of the main body of the drainage tube, the rotation of the first bevel gear is converted into the rotation of the second bevel gear perpendicular to the axis of the main body of the drainage tube, and the rotation of the second bevel gear passes through the connecting rod, This translates into a rotation of the piercing head.

Preferably, the main body of the drainage tube is also provided with a flushing tube, and the flushing tube is arranged inside the main body of the drainage tube. There is a flushing tube, which can flush the body and drain the flushing fluid out of the body in time, which can effectively improve the flushing efficiency.

Preferably, the irrigation tube is arranged outside the main body of the drainage tube.

Preferably, the length of the end of the drainage tube body away from the puncture head can be adjusted. In this way, the length of the main body of the drainage tube can be shortened during CT-guided puncture, and after the puncture is completed, the length of the main body of the drainage tube can be extended to achieve the purpose of drainage.

The beneficial effects of the utility model are:

1. In this utility model, a movable joint is designed between the drainage tube and the puncture head, and an adjustment device is set on the drainage tube, which can flexibly adjust the direction at multiple angles, so that it is not limited by the angle and direction of puncture outside the body, and can flexibly avoid organs , blood vessels, to ensure safe operation, angle adjustment is carried out outside the body, flexible operation, not limited by angle and direction;

2. The puncture drainage tube of the utility model has a built-in cannula, which can realize flushing and drainage at the same time, so that the drainage is more sufficient, and the clinical treatment is more thorough and effective;

3. The built-in cannula of the puncture drainage tube of the utility model is retractable. After the puncture direction is determined, the length of the built-in cannula can be flexibly released. Combined with the above-mentioned flexibility in direction, the puncture treatment ability and safety can be greatly improved.

4. For the puncture treatment that cannot be completed under the guidance of B-ultrasound, the puncture is feasible under the guidance of CT. The utility model can greatly reduce the number of CT scans, thereby reducing the radiation damage to the body.
