Description

Technical Field

[0001] This invention belongs to the field of medical device technology, and more specifically, relates to a surgical anesthesia intubation forceps. Background Technology

[0002] During medical surgery anesthesia, an endotracheal tube needs to be inserted into the trachea to ensure normal breathing. For example, patent application number CN201710351756.4 discloses a surgical anesthesia intubation forceps with a visible and easily replaceable camera. It includes a semi-circular fixing block, which is connected to a semi-circular moving block through a reset device. The left end of the semi-circular fixing block is fixedly connected to the lower part of the inner wall of the sleeve, and a button is fixed to the upper side of the sleeve. This surgical anesthesia intubation forceps with a visible and easily replaceable camera is convenient to use, reduces the workload of medical staff and reduces the pain of patients when inserting endotracheal tubes.
