TC Cottle Dorsal Angular Scissors – 16 cm Rhinoplasty Blade Control

TC Cottle Dorsal Angular Scissors, SKU PS-3171, are reusable ENT and plastic surgery scissors manufactured from German stainless steel with tungsten carbide cutting inserts for controlled nasal dorsal dissection, cartilage trimming, and soft tissue division. The available size variant is 6 1/4 inch 16 cm model PS-3171, configured with angled curved blades, long shanks, a screw joint, ring handles, gold-tone handle finish, and TC cutting edges. The angular working profile is used during rhinoplasty, septorhinoplasty, septoplasty, dorsal hump reduction, upper lateral cartilage release, mucoperichondrial flap refinement, nasal valve exposure, scar band division, vestibular soft tissue adjustment, and veterinary nasal soft tissue procedures. The blade curve supports controlled cutting along the nasal dorsum and septal framework while the angled shaft improves access when the hand must remain outside the direct visual corridor. ENT surgeons, facial plastic surgeons, plastic reconstructive surgeons, maxillofacial teams, veterinary surgeons, hospitals, clinics, ambulatory surgery centers, distributors, and procurement departments use this pattern where fine cutting control and reusable tray compatibility are required.

Angular Blade Geometry and Screw Joint Cutting Action

The Cottle dorsal angular pattern works through a curved cutting blade mounted on an offset shaft, allowing the surgeon to approach nasal tissue from an angled trajectory while maintaining hand clearance. The blade profile follows the contour of the nasal dorsum and septal framework, supporting controlled division of soft tissue, fibrous attachments, cartilage edge, and scar bands. Tungsten carbide cutting inserts provide a hard working interface that maintains cutting response through repeated use on cartilage-adjacent and fibrous tissue. The screw joint controls blade opposition so the cutting edges meet progressively during each closure stroke. Long shanks keep the ring handles away from the incision and improve visibility under headlight, loupe, or endonasal exposure. The curved distal profile helps the operator cut along a controlled arc rather than forcing a straight vertical path. Gold-tone handles identify the TC pattern inside ENT and plastic surgery trays. The 16 cm length balances fine distal control with enough reach for nasal dorsal and septal access.

Rhinoplasty, Septoplasty, and Nasal Dorsal Workflow

During rhinoplasty, TC Cottle Dorsal Angular Scissors are used after exposure of the nasal framework when fibrous attachments, soft tissue layers, or cartilage margins require controlled division. In dorsal hump reduction, the angled curve supports access along the dorsal line while retractors and skin-soft tissue envelope elevation create a narrow working corridor. During septoplasty, the scissors can refine mucoperichondrial tissue margins and trim selected septal cartilage edges where a curved cutting path improves control. In septorhinoplasty, the pattern assists around upper lateral cartilage release, dorsal refinement, nasal valve exposure, and scar tissue separation. Facial plastic surgeons may select the instrument during revision cases where adhesions and fibrous bands require short, deliberate cutting strokes. ENT teams use the same geometry for endonasal or open approaches where hand position must not obscure the field. Veterinary surgeons can use the 16 cm profile for nasal soft tissue access and delicate facial procedures in small animal operating rooms.

16 cm Model PS-3171 Selection Rationale

The 6 1/4 inch 16 cm PS-3171 size is selected when the operative field requires a compact scissors pattern with enough shaft length for nasal dorsal and septal work. This length keeps the ring handles manageable while placing the curved blade at the target tissue plane. In open rhinoplasty, the 16 cm frame supports cutting around the nasal dorsum without excessive handle bulk near retractors. In septoplasty, the size allows controlled trimming inside a restricted corridor while preserving tactile feedback at the distal end. In revision nasal surgery, the shorter long-shank balance helps separate scar tissue in small increments. Compared with longer dissecting scissors, this model reduces distal weight and improves hand response. Compared with shorter superficial scissors, it provides more reach for deeper nasal and vestibular access. Hospitals can stock this size for ENT sets, facial plastic trays, rhinoplasty instruments, septoplasty packs, maxillofacial units, and veterinary facial surgery inventories.

German Stainless Steel, TC Edges, and Procurement Documentation

German stainless steel provides the rigidity, corrosion resistance, and dimensional stability required for reusable angled scissors exposed to repeated cutting, cleaning, and steam sterilization cycles. Tungsten carbide cutting inserts support durable edge performance during controlled division of nasal soft tissue, fibrous bands, and cartilage-adjacent planes. The satin, dull, or mirror finish options allow facilities to match operating room lighting preference and inspection workflow, while the gold-tone handles identify the TC working pattern. Reprocessing follows standard central sterile procedures, including point-of-use preparation, manual cleaning of blade edges and the screw joint, ultrasonic cleaning where used, washer-disinfector processing, drying, edge inspection, sterile packaging, and autoclave sterilization. The screw joint requires focused cleaning because blood, protein residue, and tissue debris can collect around the moving interface. CE marking and ISO 13485 alignment support regulated purchasing documentation for hospitals, clinics, and distributors. FDA-compliant procurement support helps United States buyers maintain records for reusable surgical instruments, while OEM availability and one-piece ordering support replacement purchasing and custom tray assembly.

How do TC Cottle Dorsal Angular Scissors differ from Metzenbaum Scissors?
TC Cottle Dorsal Angular Scissors are designed with an angled curved working profile for nasal dorsal and septal access. Metzenbaum Scissors are general soft tissue scissors used across broader surgical closure and dissection tasks. The Cottle pattern gives better approach control when the cutting line follows the nasal dorsum, upper lateral cartilage, or septal tissue plane. Metzenbaum patterns are usually selected when the field does not require an angular nasal approach. TC Cottle Dorsal Angular Scissors also use tungsten carbide cutting inserts for durable edge performance. This makes the Cottle pattern more suitable for rhinoplasty, septoplasty, septorhinoplasty, facial plastic surgery, ENT trays, and veterinary nasal procedures.

When should the 16 cm TC Cottle Dorsal Angular Scissors size be selected?
The 16 cm TC Cottle Dorsal Angular Scissors size is selected when the surgeon needs controlled cutting in a narrow nasal or facial operative field. In rhinoplasty, the length provides access to the nasal dorsum while keeping the handle outside the direct visual line. In septoplasty, it supports trimming near septal cartilage and mucoperichondrial tissue without using a bulky long scissors. In revision nasal surgery, the compact frame helps divide scar bands in short controlled strokes. The size is also practical for maxillofacial and veterinary facial soft tissue work. Selection depends on field depth, retractor placement, cutting angle, tissue density, and the surgeon’s preferred hand clearance.

What do CE, ISO 13485, and FDA-compliant procurement mean for this product?
TC Cottle Dorsal Angular Scissors are supplied for healthcare purchasing workflows that require traceable instrument documentation. CE marking supports regulated distribution where European conformity documentation is required. ISO 13485 alignment indicates that the manufacturing quality system follows a recognized medical device framework. FDA-compliant procurement support helps buyers serving United States healthcare channels maintain records for reusable surgical instruments. Hospitals can use these references during vendor onboarding, internal product review, and recurring supply approval. Distributors can include PS-3171 in ENT, plastic surgery, maxillofacial, rhinoplasty, septoplasty, and veterinary procurement programs.

How is the screw joint used during nasal dissection?
The screw joint on TC Cottle Dorsal Angular Scissors controls the movement and alignment of the two cutting arms. When the surgeon closes the ring handles, the joint guides blade opposition so the TC cutting edges meet in a controlled sequence. This action supports precise cutting through nasal soft tissue, fibrous bands, cartilage-adjacent planes, and scar tissue. Proper joint alignment helps the curved distal blades maintain predictable contact during short rhinoplasty or septoplasty strokes. The angled blade profile works with the joint to keep the cutting path controlled while the hand remains outside the visual corridor. After surgery, the screw joint requires focused cleaning because tissue residue can remain around the moving interface.

How should hospitals, clinics, and distributors manage sterilization and supply?
TC Cottle Dorsal Angular Scissors are reusable instruments suited for standard central sterile processing workflows. After surgery, the TC blade edges, curved tips, screw joint, shanks, and ring handles require prompt cleaning preparation. The instrument can then be processed through validated cleaning, drying, inspection, sterile packaging, and steam autoclave cycles. Hospitals can stock PS-3171 for ENT, plastic surgery, rhinoplasty, septoplasty, maxillofacial, and veterinary trays. Clinics and distributors can order single replacement units or include the scissors in custom nasal surgery sets. Procurement teams receive return and replacement support, tracking assistance, and documentation support for institutional purchasing.
