Surgical suction cutter device

Console

Basic Specifications

Power Supply: Input 100-240VAC, 50-60Hz
Dimensions: Approx. 277mm(W)×353mm(H)×267mm(D) (ref. Medtronic IPC)
Weight: Typically <7.5kg

Universal voltage, adapts to different hospital power supplies. Console should be compact and portable.

Smart Functions

Auto-identification: Automatically identifies handpiece and blade/bur type, recommends or sets default parameters
Fault Diagnosis: Self-diagnosis and protection technology
Constant Speed Drive: Speed drop under load ≤5%

Simplifies operation and ensures safety.

Display & Interface

Display: High-resolution touchscreen showing real-time speed, rotation direction, blade angle, irrigation volume, etc.
Handpiece Ports: Multiple ports for connecting nasal, ear, etc., handpieces simultaneously

Clear, intuitive information and easy operation.

Expandability

Software Upgrade: Via USB or flash card
Irrigation Pump: Built-in peristaltic pump, adjustable flow (e.g., 0.5-100 ml/min), foot-controlled synchronous irrigation

Facilitates future function expansion and maintenance.

Handpiece
(Nasal / Ear / Laryngeal)

Speed & Torque

Nasal Shaver Handpiece: Unidirectional speed ≥12,000 rpm (continuous rotation), reciprocating ≥5,000 rpm (oscillating cutting)
Ear / High-Speed Drill Handpiece: Max. speed up to 60,000-80,000 rpm
Torque: Approx. 47.5-90 mNm

Torque is a key indicator of cutting power. High-speed drills often require dedicated high-torque handpieces.

Physical Characteristics

Design/Weight: Pen-grip design for delicate operation, weight typically <240 g
Material: Mostly titanium alloy
Sterilization: Handpiece body and cable withstand autoclaving (134℃)

Lightweight, ergonomic design, and good sterilization tolerance reduce surgeon fatigue.

Key Design Features

In-line Suction: Cutting and suction in a straight line, effectively prevents intraoperative clogging
360° Rotation: Allows 360° rotation of the blade tip
Cooling Method: Air-cooled for nasal handpieces, water-cooled for high-speed ear drills

In-line suction is a core standard for handpiece design.

Blades / Burs

Blades

Angles: Common angles: 0°, 12°, 40°, 60°, 120°, etc.
Diameter/Length: Diameter typically 2.9-5.0 mm, length typically 11 cm
Types: E.g., nasal polypectomy blade, adenoidectomy blade, laryngeal polyp forceps

Angles, diameters, and lengths must precisely match the surgical anatomy.

Burs

Types: Cutting bur (tungsten carbide, sharp) for rapid bone removal; Diamond bur (diamond grit, fine) for delicate polishing
Diameter: Ranges from 1.0 mm to 8.0 mm
Length: From 40 mm to 140 mm depending on procedure

Choose bur material based on surgical goal (e.g., fenestration vs. bone grinding).

Foot Switch

Basic Functions

Control: Stepless speed adjustment, rotation direction switching, blade opening angle control, etc.
Waterproof Rating: Typically IPX8, allows immersion

Anti-slip, anti-tip design reduces operator fatigue.
