Description
Technical Field
The invention relates to the technical field of surgical instruments, in particular to a closed drainage tube-placing device for a thoracic cavity.
Background
Closed drainage of the thoracic cavity is one of the common procedures of the endo-surgery and critical medical department. The closed drainage of thoracic cavity is to put one end of the drainage tube into thoracic cavity or pus cavity and the other end is connected with the drainage bag or water sealed bottle, in order to discharge the intrathoracic gas or the liquid in the thoracic cavity or the pus cavity, to re-open the lung tissue to restore the function or to discharge necrotic infection outside the body. Can be widely used for treating pneumothorax and various hydrothorax (hemopneumothorax, empyema, etc.).
The existing thoracic closed drainage generally has the following defects that a drainage tube is directly inserted into a skin incision:
1. the traditional vascular forceps clamping catheter implantation method has the defects that the skin incision is large, a plurality of needles are sutured after the drainage tube is implanted, the drainage tube is directly implanted after being clamped by the vascular forceps, the blunt separation degree is large, the inner diameter of a separated potential tunnel is larger than the outer diameter of the drainage tube, if the implantation is difficult, the implantation needs to be performed for many times, the repeated operation is needed, and subcutaneous tissues or muscle tissues of a puncture part are damaged.
2. The closed drainage of the chest cavity is provided with a needle chest tube method, a hard needle core is arranged in the chest tube, for example, the needle core is operated under violence, and can be placed too deeply to damage internal organs (lung or heart) of the chest cavity, so that iatrogenic injury is caused, and the operation risk exists; the chest tube with the needle is linear and cannot be bent, so that the chest tube with the needle cannot be fed into the target direction; furthermore, the needle chest tube method cannot form a tunnel in advance, so that the operator is not allowed to perform probing with a finger, thereby reducing the treatment effect of forming a divided abscess.
3. The back pumping action cannot be completed in the operation process, and the gas or liquid cannot be pumped back so as to confirm that the puncture path is correct.
4. The learning curve of the above-described solution is long or requires a certain surgical basis and cannot be generally mastered by ICU doctors. If a patient in the ICU has pneumothorax or hydrothorax to cause respiratory failure, immediate intervention is often required, and waiting for consultation by a chest surgeon often delays treatment.
Therefore, we propose a closed drainage catheterization device for thoracic cavity.
