母羊生殖器官的B超探查

Sonography of the Reproductive Organs in Ewe

通过活体B超探查和屠宰对比观察,对母羊的生殖器官进行了研究。结果表明:用3.5MHz扇扫探头作体表探查时的最佳位置是在股内侧、乳房后上侧方的少毛区。用5.0MHz线阵探头经直肠探查时羊取自然站立保定,掏除直肠内宿粪后用消毒剂润滑过的长柄探头缓缓插入肛门,探头探测面朝下,并作45度角扫查,即可依次显现阴道、子宫颈、膀胱、子宫角和卵巢的声像图。在膀胱液性暗区前下方清晰可见子宫和卵巢为中等强度的回声结构,其包膜周边回声界限明显。强回声带声影的耻骨联合可作为盆腔和腹腔的分界线。其声像图结果经术中B超探查和水浴B超探查所证实。

In order to confirm the positions of the reproductive organs in living body such as vagina, uterine, ovary and the nearby organs from the uhrasonogram taken with B-mold ultrasound scanner, slaughter of ewes was used as the control. The results indicated that the optimum position for the transcutaneous scan with 3.5 MHz sector probe was in the less hair area between thigh inner and breast upper. The 5.0 MHz linear probe was used for transrectal scan. The ewe was restrained standby, and the faeces in rectum was removed. The long-handle probe was inserted into the anus slowly with the scanning side facing below. The ultrasonogram of vagina, cervix, urinary bladder were presented. Then it will present uterus and ovary when the probe scanned frontally and within 45 angles. The medium-intensity echo structure of the uterus and ovary were seen cleanly in front of the anichoic area of urinary bladder. The hyperechoic surround membrane was distinct. The hyperechoic pubis with acoustic shadow was found in the borders between belly and pelvic cavity. The uhrasonograms were confirmed by immersion scan and intraoperative scan.
