Obstetrical Instruments TRIZ Cases

An inflatable clasp and trigger-actuated rod elevate the fetal presenting part to prevent umbilical cord compression during caesarean preparation.

A flexible sealing member creates an ergonomic seal during biofluid collection to reduce spillage, contamination, and user discomfort.

Pivotable end-effector connections help position the prostate precisely while reducing surrounding tissue damage during surgery.

Gel-filled silicone pads provide compliant cervical gripping and countertraction, preserving visualization during transcervical procedures.

A self-retaining ring and adjustable retractors manage pannus and incision access while reducing assistant strain during caesarean delivery.

Elastomeric patch seals amniotic membrane using wet-activation adhesive, preventing iPPROM while preserving natural sliding movement.

Intracavitary brachytherapy applicator uses inflatable ovoids and retractors to position the bladder and rectum away from radiation sources.

Curved arms apply distributed pressure to free a stuck shoulder, reducing injury risk during delivery.

Woven metal occlusion device prevents chorioamniotic separation during fetoscopic surgery via expandable hourglass structure.

Flexible cylindrical structure expands within vaginal canal to retract swollen tissues and manage fluids without external handles.

A vaginal manipulator employs a textured interior surface to grip the cervix, preventing slippage in wet environments and enabling precise tissue manipulation.

An integrated uterine manipulator combines a tenaculum clamp and colpotomy ring with variable length tips to prevent slippage during hysterectomies.

A vaginal cup stores sperm near the cervix while a string facilitates removal to improve ease of operation.

Flexible intravaginal cup presents ejaculate near the cervix after inversion, addressing rigid-shaft trauma and painful insertion.

Inclined support lugs and a flexible rim distribute contact pressure to reduce manual force requirements during fetal head positioning.

An inflatable surgical device lifts impacted fetal heads during cesarean sections using controlled pneumatic force.

Rotating instrument deploys elastic belt to stabilize cervix, eliminating surgical risks and anesthesia requirements.

An integral vaginal speculum eliminates the nut-screw mechanism by allowing direct manipulation of supporting members, reducing examination time.

A cervical stabilization device uses a flexural moment center to adjust positioning and inflate bladder portions around the cervix.

A nonlinear guide converts linear actuation into bidirectional rotation, enabling large pivot ranges without complex multi-degree-of-freedom mechanisms.

An articulating obstetric spatula combines two independent spoons into a unified forceps configuration to enable firm fetal head traction.

A uterine clamp uses ball-and-socket joints to position curved plates against the uterus.

A frame applies mechanical pressure to constrict blood flow during Caesarean delivery operations.

An LED array illuminates internal tissue to enhance surgical visibility during minimally invasive procedures.

A vaginal manipulator door features an inclined surface that reflects light from hidden organ areas to the camera.

Composite grasping members with distinct stiffness sections reduce polymer tube fatigue during repeated reciprocating movements.

Curved arms with adjustable friction hinges provide unobstructed surgical views while maintaining stable tissue exposure during vaginal procedures.

Segmented upper and lower members nest within a compact profile to pass through small trocar ports while maintaining reliable clamping force.

An inflatable bladder distributes fetal weight to the vaginal wall, reducing strain on the cervix and preventing premature dilation without invasive suturing.

A cervical stabilization device uses a flexural cup and inflatable bladder to support the uterus.

Pressure-transmitting jaws compress blood vessels to prevent bleeding from sharp-pointed hooks.

A fetal head elevator uses a flared support and lever arm to reposition the fetal head during delivery.

Segmented retracting members clear obstructing labial tissue from the field of vision while an integrated absorbent panel manages fluids.

An ovarian insert supplies blood externally through a surgical incision, avoiding tissue destruction from drilling.
