in the figure, the puncture device comprises ahandle 1, ahandle 2, a protective sleeve 3, a display screen 4, a first interface 5, an ultrasonic probe 6, a power switch 7, a depth adjusting key 8, a gaincompensation adjusting key 9, askin contact end 10, asecond interface 11, apuncture sheath 12, apuncture guide hole 13 and a puncture fixer.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-2, a cricothyroid membrane puncture guiding device comprises ahandle 1 and aprotective sleeve 2, wherein a display screen 3 is arranged at one end of thehandle 1, and a first interface 4 is arranged at the other end of thehandle 1. Be equipped with ultrasonic probe 5 in the interface 4, be equipped with the controller in thehandle 1, be equipped with switch 6, degree of depth adjustment key 7, gain compensation adjustment key 8 on the 1 outer wall of handle, the controller respectively with ultrasonic probe 5, degree of depth adjustment key 7, gain compensation adjustment key 8 electric connection to adjust ultrasonic probe 5's detection depth through degree of depth adjustment key 7, gain compensation adjustment key 8. One end of theprotective sleeve 2 is askin contact end 9, theskin contact end 9 is crescent-shaped, and can annularly wrap the skin in front of the neck, so that the trachea and surrounding tissues can be clearly displayed during ultrasonic exploration. Theskin contact end 9 is provided with a solid couplant, and the other end of theprotective sleeve 2 is provided with asecond interface 10. A cavity is arranged in theprotective sleeve 2, the first interface 4 is in butt joint with thesecond interface 10, and the ultrasonic probe 5 extends into the cavity of theprotective sleeve 2. Thepuncture sheath 11 is arranged on theprotective sleeve 2, thepuncture guide hole 12 is arranged on thepuncture sheath 11, thepuncture sheath 11 is connected with theprotective sleeve 2 through thepuncture fixer 13, and thepuncture fixer 13 is a bandage. Thepuncture sheath 11 is hinged with thepuncture fixer 13, so that the angle between the central shaft of thepuncture guide hole 12 and the central shaft of the ultrasonic probe 5 can be adjusted, and the head end of the puncture needle can be developed in an ultrasonic detection plane when thepuncture sheath 11 is used for performing cricothyroid membrane puncture.
