Description

Technical Field

[0001] The utility model relates to the field of lung surgery, in particular to a puncture sheath needle for lung surgery. Background Art

[0002] Pulmonary surgery refers to a range of surgical procedures performed on the lungs to diagnose, treat, or prevent lung disease. These procedures can be open or minimally invasive, such as laparoscopic or endoscopic. There are many different types of lung surgery, depending on the nature and location of the lesion, the patient's overall health, and the surgeon's discretion.

[0003] During lung surgery, a puncture sheath needle is usually required to establish a channel for biopsy or other treatment operations. The puncture needle is used for initial puncture, while the sheath establishes a channel along the puncture needle so that subsequent operations can proceed smoothly. This design helps to reduce damage to surrounding tissues and provide a stable channel for various interventional surgeries. However, the needle and sheath of the current puncture sheath needle are not easy to disassemble, which makes it time-consuming and laborious for medical staff to perform surgeries that require the replacement of different types of needles. After the sheath is inserted into the patient's body, the medical staff usually needs to hold it in their hands to fix it, which means that the medical staff's hands cannot be freed, making it inconvenient to use.

[0004] In view of this, in order to solve this technical problem, the present application proposes a puncture sheath needle for lung surgery. Utility Model Content
