Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a stent loading device. Background Art

[0002] The human respiratory system is composed of the respiratory tract and lungs. The respiratory tract below the cricoid cartilage is called the bronchus. The bronchus can transport the inhaled air to the alveoli for gas exchange and effective breathing. When the bronchi become narrow or softened due to factors such as tumors and tuberculosis, gas delivery may be hindered, causing hypoxia or even suffocation in the patient. Therefore, during treatment, the bronchial stent needs to be delivered into the bronchus through the inserter and the bronchial stent is stretched open. The bronchial stent is used to support the narrowed or softened bronchi to ensure that the patient's airway is unobstructed. Because the bronchial stent is elastic and can open automatically, the bronchial stent needs to be pushed into the conical loader for contraction before being delivered and then pushed into the inserter. At present, the existing loader includes a conical loading shell and a push rod, and has a relatively simple structure. When operating, the staff needs to put the bronchial stent on the push rod, and then insert the push rod into the loading shell for pushing. At the same time, one end of the inserter needs to be inserted into the loading shell to receive the bronchial stent after pushing and contraction. With this loading method, the push rod cannot completely push the bronchial stent into the insertion cavity in the loading shell, which causes the loaded bronchial stent to be partially exposed, and the bronchial stent is likely to fall off or be contaminated, affecting the use of the bronchial stent.
