 1. Outlet Wrigley Forcep

Video

🔩 CONSTRUCTION:

  • Length: Shorter than other obstetric forceps (approx. 27 cm)
  • Curves:
  • Cephalic curve – fits around the fetal head.
  • Pelvic curve – very shallow or almost absent (used when head is already low in birth canal).
  • Handles: Large with finger grips, connected with a locking screw or English lock.

  • Shanks: Short, limiting their use to outlet forceps delivery only.

  • Blades: Broad, fenestrated (to reduce pressure), rounded.


🎯 INDICATION (Critical):


  • Only used for outlet forceps delivery, when:
  • Fetal head is on the perineum
  • Scalp is visible at introitus without separating labia
  • Sagittal suture is in anteroposterior diameter or slight rotation (≤45°)
  • No cephalopelvic disproportion


💥 Remember: It is not for mid-cavity or high forceps. Using it above station +2 is negligence.


👩‍⚕️ OBSTETRIC APPLICATION:


  • Primary Use: Outlet delivery to assist maternal expulsive efforts when:
  • Maternal exhaustion
  • Poor pushing effort (e.g., after epidural)
  • Fetal bradycardia needing rapid delivery
  • Also used during cesarean section to deliver deeply engaged head (“push vs pull” dilemma)


⚔️ ADVANTAGES:

  • Short length = safer → less risk of uterine or vaginal trauma
  • Ideal for crowning head
  • Excellent control on fetal head flexion


☠️ COMPLICATIONS (If misused):

  • Fetal: Facial palsy, skull fracture, cephalohematoma
  • Maternal: Vaginal/perineal tears, PPH, hematoma


🔍 MASTER'S CLINICAL PEARL:

> “When head is low, and perineum is stretched like a drum – that’s Wrigley’s time. Any higher, and you’ve just turned help into harm.”


👨‍⚕️ VIVA QUICK FIRE:

Q: Why is Wrigley’s forceps short?

A: Designed for outlet deliveries to avoid injuring maternal soft tissues.


Q: Why not used in mid-cavity forceps delivery?

A: Short shanks can’t reach mid-pelvis; applying force here can injure uterus/vagina.


Q: In C-section, why use Wrigley’s?

A: To lift deeply engaged head gently through uterine incision – prevents extensions.


2. Uterine curette



MedInstinct – Strict clinical mode activated.

Today, we master the Uterine Curette — no shortcuts, no superficial understanding.



---


🔪 DEFINITION


A uterine curette is a gynecological instrument used for scraping or removing tissue from the endometrial lining of the uterus.



---


🛠️ TYPES


1. Sharp Curette


Metallic loop with sharp edges.


Used for diagnostic or therapeutic D&C (dilatation & curettage).


Risk: Higher chance of uterine perforation.




2. Blunt Curette (or Suction Curette)


Rounded, with gentle edges.


Used in suction evacuation (especially in 1st-trimester MTP or incomplete abortion).


Connected to suction device.






---


📏 PARTS OF THE CURETTE


1. Handle – Long and firm for grip.



2. Shank – Long shaft for uterine reach.



3. Tip/Loop –


Sharp for scraping.


Blunt or perforated for suction.


Comes in different sizes based on uterine cavity.






---


🎯 USES / INDICATIONS


1. Diagnostic


Evaluation of abnormal uterine bleeding (AUB).


Suspected endometrial hyperplasia or carcinoma.


Infertility workup (endometrial dating).




2. Therapeutic


Removal of retained products of conception.


Management of incomplete abortion.


Endometrial polyp or small fibroid removal.




3. Obstetric / Gynec Procedures


Dilation & Curettage (D&C).


Manual Vacuum Aspiration (MVA) (with suction curette).


Postpartum retained placental bits (caution: risk of perforation).






---


⚠️ COMPLICATIONS (CLINICAL MUST-KNOW)


Uterine perforation – especially with sharp curette.


Infection – endometritis, PID.


Intrauterine adhesions (Asherman's syndrome) – from aggressive curettage.


Hemorrhage – if a large vessel is injured.




---


🔍 CLINICAL TIPS


Always rule out pregnancy before D&C.


Use blunt curette in postabortal cases to reduce perforation risk.


For postmenopausal bleeding, sharp curettage may help obtain adequate endometrial sample.




---


💡 VIVA/OSCE PEARLS


Q: Why is a suction curette preferred in early abortions?

A: Less traumatic, better evacuation, safer.


Q: Why avoid sharp curette in suspected pregnancy?

A: Risk of perforation and excessive bleeding.


Q: What is Asherman's syndrome?

A: Intrauterine adhesions due to overzealous curettage.

🧠 Mnemonic: "CUR-ETTE"


C – Cavity clearing


U – Uterine contents removed


R – Risks: rupture, reaction


E – Endometrial biopsy


T – Therapeutic & diagnostic


T – Types: sharp/blunt


E – Evacuation in abortion

If you want video generation in 8-second segments (YouTube Shorts style), reply with "Yes, 8-sec script", and I’ll break this into multiple short-form educational reels.


Or ask about comparison with Ventouse, or forceps in obstetrics, and I’ll continue.


Ready for your viva. No excuses. Only mastery.
