Technical Field

The invention relates to a medical instrument for surgical emergency operations, in particular to a using method of a closed thoracic drainage puncture outfit, and belongs to the field of medical instruments.

Background

Pneumothorax refers to the chest cavity only containing gas, and hemothorax refers to the chest cavity blood accumulation, and the two are coexistent. Pneumothorax is divided into spontaneous pneumothorax and traumatic pneumothorax.

The pathogenesis of spontaneous pneumothorax is that the pulmonary internal pressure is suddenly increased, so that alveoli are ruptured, and gas enters the thoracic cavity through a fissure hole; spontaneous pneumothorax causes compression of lung, which can pull the adhesive tape to cause tearing of the adhesive tape and rupture and bleeding of arterioles in the adhesive tape, resulting in spontaneous hemothorax. Most of patients with spontaneous hemopneumothorax have a weak structure of part of alveolar walls due to congenital development defects of lung structures, so that large alveoli of lung are formed. Traumatic pneumothorax refers to the hematocele and pneumatosis in the pleural cavity caused by the trauma of the chest. The attack of hemopneumothorax caused by chest trauma accounts for more than 70% of the chest trauma, and hemopneumothorax can also occur independently or be combined with other types of chest trauma, such as penetrating or closed chest wall injury, rib fracture, mediastinal injury, combined chest and abdominal injury, chest foreign body and wound asphyxia, injured wet lung, explosive injury, three syndromes of closed chest injury and the like, and can be combined with hemopneumothorax. Mediastinal displacement, mediastinal swing and abnormal breathing caused by traumatic pneumothorax are one of the main causes of death due to chest injury, and need to be treated by emergency surgery.

With the rapid development of the current national economy and the popularization of automobiles, various wounds and multiple wounds are increasing day by day, and the probability of emergency thoracic closed drainage to obtain life saving is gradually increased. Pneumothorax is extremely prone to chest trauma, especially penetrating trauma. The literature reports that pneumothorax occurs in 70% of thoracic wounds, and in particular in 60% of thoracic wall penetrating wounds. Severe hemopneumothorax interferes with the respiratory and circulatory functions of the body. Closed thoracic drainage is the most common emergency treatment for hemopneumothorax. The existing closed thoracic drainage is mostly performed by cardiothoracic surgeons, and for the current rapidly developed emergency medical science, clinicians including emergency physicians, even ordinary persons with basic rescue skills are undoubtedly required to take corresponding emergency measures in the shortest time to save the life of each patient. Clinical special research has a multiple functional, easy operation, safe practicality, makes things convenient for the extensive practical wicresoft's thorax drainage puncture instrument of each branch of academic or vocational study, like wicresoft's thorax closed drainage instrument (the national intellectual property of the people's republic of China utility model, patent number 200520115206.5), independently accomplishes thorax closed drainage in the shortest time, reaches and corrects breathing, circulation disorder, resumes the purpose of normal physiology. This wicresoft's thorax closed drainage apparatus has a bullet expansion pipe that is equipped with the seal wire entry, and the cover has a stay tube on the expansion pipe, is equipped with a pair of ear hole of pulling on the outer wall of stay tube and refers to the snap ring as jointly, pulls and has one to pull the steel ring on the ear hole, and its working process is: firstly, trying to wear a part to be cut with blood and gas by using a central venous puncture needle, then pulling out the puncture needle, cutting the skin by using a sharp knife, using a T-shaped triangular pyramid to chisel partial muscle of the chest wall, inserting a venous guide wire, penetrating the distal end of the guide wire into a bullet expansion tube through an inlet, forcibly rotating the bullet expansion tube to push the bullet expansion tube into the chest cavity, quickly pushing a support tube on the expansion tube into the chest wall, establishing a temporary channel, pulling out the expansion tube and the guide wire, quickly plugging the tube opening by using the thumb of a left hand, and immediately inserting the three-cavity air bag sterile catheter. The three-cavity air bag sterile catheter can remove hematocele and pneumatosis in the pleural cavity, correct respiratory cycle disorder and restore normal physiological function.

However, the minimally invasive closed thoracic drainage instrument has the following inconveniences: firstly, puncture complex operation is inconvenient, and the puncture operating means is more, extravagant treatment time. Firstly, a central venous puncture needle is used for trying on a part to be cut, then the puncture needle is pulled out, a sharp knife is used for cutting the skin, then a T-shaped triangular pyramid is used for puncturing the muscles of the chest wall part, and finally a minimally invasive thoracic closed drainage instrument is inserted, so that gold time for first aid is wasted after the chest wall is punctured for many times. Secondly, puncture in the chest wall repeatedly, it is difficult to look for the puncture passageway of the last time, increases the wound, and in this instrument of trading many times, the thorax internal blood can outwards gush out, covers the thorax opening, and chest wall muscle contracts, all probably leads to puncture passageway to look for difficultly, and the time waste looks for the thorax puncture passageway, and the mistake treatment time is delayed, causes again to cause the wound increase in the puncture simultaneously. Thirdly, the puncture depth is not easy to control, iatrogenic trauma can be caused by puncturing the chest wall for multiple times, the puncture depth is not easy to master in the chest wall puncture process, effective puncture cannot be realized if the puncture depth is too shallow, and damage to the viscera of the thoracic cavity can be caused if the puncture depth is too deep. Fourthly, in the process of repeatedly puncturing the chest wall by various tools, the probability of bacterial contamination of the chest cavity is increased, and the tools are more complicated to operate, so that the probability of infection caused by untight sterilization of the tools or various operations is increased.
