What is the Doyen Myoma Screw and Tumor Lifter and what is its primary surgical function?
The Doyen Myoma Screw and Tumor Lifter (Myom-Heber) is a heavy-duty gynecological surgical instrument measuring 170 mm in length, designed specifically for the mechanical fixation and traction of uterine fibroids (leiomyomas). Featuring a sharp corkscrew spiral tip and a broad ergonomic T-handle, it is screwed clockwise into the dense core of the fibroid, establishing an immovable anchor point that allows the surgeon to elevate and tract the tumor away from the myometrial bed, facilitating rapid, bloodless dissection and enucleation.
Clinical Significance of Doyen Myoma Screw and Tumor Lifter in Gynecological Surgery
Surgical enucleation of large intramural or subserosal uterine fibroids often presents technical challenges due to the slippery, rubbery consistency of dense fibrous tissue. Standard grasping forceps frequently slip or tear the tumor capsule, resulting in troublesome bleeding and prolonged operative times. The Doyen Myoma Screw and Tumor Lifter resolves this difficulty through positive internal anchoring. By embedding deep into the fibrous parenchyma, the corkscrew allows multidirectional traction. This elevated tension exposes the avascular plane between the pseudo-capsule and normal myometrium, permitting swift electrocautery or blunt dissection while minimizing intraoperative blood loss.

Manufacturing Quality Tiers for Doyen Myoma Screw and Tumor Lifter
To satisfy rigorous hospital procurement standards across tertiary university centers, military health complexes, and private specialized clinics, Alreda Medical supplies this crucial instrument across three certified tiers:
1. German Industry Grade (German Grade)
Precision-milled box lock hinge that eliminates shank play, laser-aligned jaw serrations for atraumatic micro-occlusion, anti-glare satin finish for bright surgical theater environments, and exceptional resistance to repeated high-pressure autoclave cycles.
Solid structural forging and high-torque welded T-bar joint ensure zero deformation or shaft shearing under aggressive lifting torque during bulky myoma mobilization, coupled with laser-sharpened spiral flutes, anti-reflective satin passivation, and superior resilience to continuous autoclave steam cycles.
2. UK Industry Grade (UK Grade)
High-tensile British surgical stainless steel providing responsive spring-back action during ratchet engagement, lightweight ergonomic balance, and reduced operator hand fatigue.
Crafted from high-tensile British surgical stainless steel delivering exceptional dynamic balance and an anatomically contoured crossbar handle that significantly reduces wrist strain and hand fatigue during long, multi-tumor enucleation procedures.
3. Pakistani First-Grade (Pakistani 1st Grade / Grade A+)
Heat-treated surgical stainless steel providing dependable clinical reliability and cost-effective durability for day-care procedural rooms, emergency trauma suites, and outpatient clinics.
Heat-treated surgical stainless steel offering dependable clinical utility and structural strength at an economical price point, representing an optimal, durable workhorse for community gynecology theaters and outpatient day-care surgical units.
Metallurgical Excellence & Corkscrew Mechanics of Doyen Myoma Screw
The metallurgical architecture of the Doyen Myoma Screw and Tumor Lifter utilizes martensitic surgical stainless steel engineered for high torsional rigidity. The spiral shaft features a progressive pitch: an acute lead point allows rapid initial penetration of the tough pseudocapsule with minimal forward axial pressure, while the broad helical threads expand backwards to distribute tensile stress across multiple tissue planes, preventing tumor stripping during vigorous upward lifting. The transverse T-bar handle is permanently fused to the central shaft via deep vacuum welding, eliminating weld-joint fatigue.

Frequently Asked Questions About Doyen Myoma Screw and Tumor Lifter (FAQ)
How is the Doyen Myoma Screw utilized during a myomectomy?
After incising the uterine serosa and reaching the fibroid pseudocapsule, the corkscrew tip is screwed clockwise into the tumor core. The solid T-handle provides reliable traction to elevate the fibroid, exposing the plane for blunt or sharp dissection without tumor slippage.
What is the clinical advantage of the Doyen screw over myoma grasping forceps?
Grasping forceps hold only the external surface and can easily tear fibrous tissue or slip when pulling heavy tumors. The Doyen screw anchors deeply into the tumor’s center, distributing traction force across the entire internal mass.
What manufacturing grades are available for Doyen Myoma Screw and Tumor Lifter?
Alreda Medical provides German Industry Grade (high torsional strength, laser-ground flutes), UK Industry Grade (ergonomic balance that reduces wrist fatigue), and Pakistani Grade A+ (cost-effective durability for day-care suites).
Is this instrument compliant with the Egyptian Unified Procurement Authority (UPA)?
Yes, it is officially coded and registered with the UPA, supplied alongside registered tax e-invoicing, and backed by our unconditional Direct Replacement Warranty.
