Definitions

  • This vaginal speculum is made of steel but it could be manufactured in plastic, as it will in the near future. It is also produced in two sizes in order to fit the various vaginal lengths. It consists of an anterior (1) and a posterior (2) blade. Their length is 115mm or 125 mm and their width 30mm. They have tips with a rounded and smooth outer surface, whereas the inside is slightly curved (2mm) (3). The tips are shaped in such a way in order to easily grasp the cervix and exert pressure on the cervical canal. This procedure is necessary in order to limit the possibility of leakage of the inseminated sperm as much as possible.
  • the base (4) of the anterior blade (1) ends in a ring with 43mm horizontal diameter and 53mm vertical diameter.
  • the handle is 80mm long, 19mm wide and 8mm thick. There are also two holes on the handle.
  • the first (6) is located 10mm below the ring and the second (7) is located 35mm under the first one (6).
  • the base of the posterior blade (2) ends in a half ring with the curve downwards and a handle (9) on 6 o'clock.
  • the handle is 80mm lomg, 18mm wide and 12mm thick.
  • Both the anterior (1) and the posterior (2) blades are connected on 3rd (12) and 9th (13) o'clock in such a way as to allow the tips (3) to open and close easily.
  • the base of the first screw (14) is set in the first socket (10) of the posterior blade (2) handle (9), whereas the tip of the screw runs through the first hole (6) of the anterior blade (1) handle (5).
  • the screw (14) is 75mm long and 5mm thick.
  • the screw-nut (15) diameter is 14 mm and is located on the outer part of the handle (5).
  • the base of the second screw (16) is set in the second socket (11) of the posterior blade (1) handle (9), whereas the tip of the screw runs through the second hole (7) of the anterior blade (1) handle (5).
  • the screw (16) is 75mm long and 5mm thick.
  • the screw nut (17) diameter is 14mm but it gradually increases to 30mm and is located on the inner part of the handle (5). Both screws (14-16) are located in their sockets in a movable way.
  • the tips of the blades (3) which reach both the anterior and the posterior vaginal vault, are opened with the help of the first screw (14), allowing good visibility of the cervix.
  • the insemination catheter is atraumatically inserted.
  • the first screw-nut (15) is released and the speculum is closed by the pressure of the vaginal wall.
  • the second screw-nut (17) is tightened and the tips of the speculum are closed and locked while its handles (5-9) are kept apart. A slight pressure is exerted on the cervix by the enveloping tips of the speculum, not at all inconvenient to the patient.
  • the international name of this particular speculum is: Double Screw Bivalve Speculum (DSB Spec or Mamas Speculum).

Abstract

Spéculum bivalve à deux vis destiné notamment à l'insémination artificielle à l'aide de spermatozoïdes placés dans l'utérus. Ce spéculum est en acier mais pourrait être en matière plastique en vue d'un usage unique, et il a deux tailles. Ledit spéculum est constitué de deux lamelles (1-2) présentant des extrémités particulières (3) à face extérieure lisse et arrondie et à face intérieure légèrement courbée. Les lamelles s'étendent dans le prolongement de poignées (5-9) sur lesquelles sont prévues deux vis et écrous (15-17). Lorsque l'on resserre la première vis (14), le spéculum s'ouvre, et lorsque l'on desserre la première vis (14) et que l'on resserre la seconde vis (16), le spéculum se ferme et demeure à l'état bloqué aussi longtemps que nécessaire. Par conséquent, on évite toute fuite du sperme utilisé pour l'insémination, ce qui permet d'augmenter la concentration de spermatozoïdes dans l'ensemble des voies génitales (cavité utérine, ampoule, cul-de-sac de Douglas), et à proximité du lieu où se produit la fécondation de l'ovule.
