Device and operating instrument set for thoracic close drainage

Abstract

The invention provides a device for thoracic close drainage. The device for the thoracic close drainage comprises an expander, a thoracic duct guide device and a thoracic duct. The expander is of a hollow or solid tubular structure made of hard materials and has certain radian, and the expander is gradually tapered from bottom end to top end. The thoracic duct is of an elastic hollow tubular structure and comprises an arc section at the front end and a straight section behind the arc section, and the top end of the thoracic duct is in an approximate conical shape. The thoracic duct guide device is provided with a pushing rod, a groove with a closed tail end and identical with the layout shape of the thoracic duct is formed in the back side, close to the top end, of the thoracic duct, the pushing rod can be inserted into the groove to push the thoracic duct to move forward, and a handle is arranged at the tail end of the pushing rod. The device and operating instrument set are convenient and safe to use and fast and accurate to operate, damage on muscles and other tissues is reduced, and the device and operating instrument set for the thoracic close drainage has important popularization and application value.

Description

technical field [0001] The application of the present invention relates to a set of devices and surgical kits for closed chest drainage, specifically, a set of devices and surgical kits including dilators, chest tube guides, chest tubes and other main instruments, which belong to medical equipment technology field. Background technique [0002] Closed thoracic drainage is a technique widely used in thoracic surgery, and it is an effective method for treating spontaneous pneumothorax, pleural effusion, empyema, and traumatic pneumothorax. Based on the principle of gravity drainage, it is an important measure to drain air and fluid in the pleural cavity, reconstruct after thoracotomy, maintain negative pleural pressure, and promote lung expansion. Its purpose is to better improve the negative pressure of the chest cavity, discharge air, blood, and fluid from the pleural cavity, prevent its reflux, promote lung recruitment, and close the pleural cavity; it can also balance pre...

AI Technical Summary

Problems solved by technology

The closed thoracic drainage currently used clinically has the following disadvantages: 1. It is necessary to use vascular forceps to repeatedly bluntly separate the muscles, causing severe pain to the patient, and it is also easy to damage the intercostal artery, resulting in massive bleeding; 2. There is no dilator , guide tube and other instruments, it is difficult to clamp the chest tube into the chest by relying solely on vascular forceps, and it requires a lot of force to insert it. It is difficult to insert the tube, and it will cause great damage to the intercostal muscles and other tissues of the chest; 3. Most of the instruments in the hospital are precious metal instruments, which need to be repeatedly sterilized and used, which is not convenient for emergency departments, wards, and ambulances. It is inconvenient to use, and it is easy to delay rescue treatment.
