Hegar Dilator Sounds Set 8 Pcs Gynecology

Product Information

Look for dilators made from body-safe materials, such as medical-grade silicone, that are free of phthalates and BPA. We manufacture Hegar dilators with premium quality surgical grade chrome plated brass that can be sterilised and reused. In addition to the points discussed above, all HL Dilators TM also act as a precise sizer. When using a Hegar dilator, the surgeon must use a separate sizer tool, whereas, with the HL Dilator TM, the surgeon can size the corpus cavernosum with the same dilator as he or she completes the dilation process [ 6]. Because a single tool has two varying dilator tips, the authors expect a positive post-operative outcome regarding inflammation and infection since fewer surgical tools are introduced inside the corpus cavernosum. During the process of dilation, the cervix may have to be stabilized with a tenaculum, and then the dilators are slowly entered into the cervical canal with a lubricant, starting with a thin, low Hegar number rod and progressing gradually to larger numbers. [11] The dilators can also be used to sound the uterus.

Osmotic dilators, such as laminaria and Dilapan-S, are established, safe, and effective ways to dilate a cervix; both require overnight placement. [9]These agents are placed through the external cervical os into the endocervical canal and absorb moisture from the cervix, slowly expanding and dilating the canal. Hegar dilators are dilators used to treat vaginismus, induce cervical dilation, and for inflatable penile implant procedures. [1] [2] Description [ edit ]Plastic curettes or cannulas are more commonly used in pregnant patients. These cannulas can be straight or curved and rigid or flexible. These cannulas are measured in millimeters; in the first-trimester abortion,a cannula between 7 mm and 12 mm isusually sufficient. The rigid plastic cannulas are slightly more challenging to place, so if the provider uses a Pratt dilator, they will dilate just past the chosen cannula size. For example, if using an 8 mm cannula, maximum dilation of the endocervical canal with a 25-26 Pratt dilator should be sufficient for cannula placement.

Pratt dilators have long tapered tips allowing the operator to use the least mechanical force; for this reason, the Pratt dilator is commonly preferred. Pratt dilators are sized from 9 to 79 French. The French unit is the diameter of the dilator in millimeters. Dividing the French unit by 3, a rough estimate of Pi, yields the diameter of the dilator in millimeters. [8] Minor discomfort is normal, but more than that means it’s time to slowly pull out and try again when you’re ready. If it goes in easily, you can start again, repeating these steps with the next size up in your kit. Typical non-gynecological uses include dilating a stenotic percutaneous gastrostomy stoma, anal dilation and urethral dilation in the case of stricture or stenosis.

According to the American College of Obstetricians and Gynecologists (ACOG) guidelines ( 2), the diagnostic criteria for simple CI are based on 3 aspects: medical history, ultrasound indicators, and a tentative diagnosis during the nonpregnancy period. Among them, the medical history is the most important for the diagnosis of CI, and a history of miscarriage in the second trimester or premature birth caused by repeated painless cervical dilatation is the direct basis for the diagnosis of CI. At the same time, a cervical canal width >0.6 cm at the internal cervical os under ultrasound examination can also assist in the diagnosis. Other diagnostic modalities of CI include: hysterosalpingography (HSG) and imaging of balloon traction on the cervix radiographically, assessment of the patulous cervix with Hegar or Pratt dilators, balloon elastance test, and graduated cervical dilators which are used to calculate the cervical resistance index based on the functional anatomy of the internal os in the non-pregnant state. In this study, CI was diagnosed upon easy passage of the No. 7 Hegar dilator through the intracervical canal.
