The present invention discloses a puncture device for treating pig ovarian cysts, including a B-
ultrasound probe fixing device and a puncture needle, and a negative
pressure system, etc. The B-
ultrasound probe fixing device, the B-
ultrasound probe matching sleeve is fixed to the position of the lumen near the convergence section, and the B-
ultrasound probe connecting line connected to the B-
ultrasound probe is led out of the lumen and connected to the input end of the B-
ultrasound probe display. The front end of the puncture needle outer sleeve of the puncture
needle guide assembly is an expansion head composed of a plurality of arc-shaped pieces, the rear port of the sleeve protrudes outward with a base, and the middle part of the sleeve has a clearance groove. The pressure rod of the pressing component is laterally pressed into the clearance groove by the
elastic component and pressed against the side wall of the puncture needle body to fix it. After pressing the
elastic component, the pressure rod can be separated from the puncture needle body. On the basis of
visualization, the present invention uses puncture, extraction, local administration and other methods to treat pig follicular cysts in the early and middle stages of the
disease, which can effectively prevent the
disease from worsening, achieve early diagnosis and treatment and
good prognosis, thereby increasing the service life of sows.
