Precision medical devices impose stringent requirements on dimensional accuracy, signal stability, and material safety. Equipment such as endoscope probes, skin imaging detectors, and micro diagnostic rotary modules are prone to cable twisting, image signal interruption, and unstable power supply during 360° continuous rotation — issues that directly affect diagnostic image clarity and device service life. The CENO ACN22T7-04-A micro hollow capsule slip ring, with its compact hollow structure, compliant eco-friendly materials, and stable multi-channel signal transmission capability, has become a key supporting component for various small and medium-sized rotary medical devices, perfectly solving the wiring challenges of medical rotating mechanisms.

I. Core Product Features That Match Medical Device Requirements

This model ACN22T7-04-A through-hole slip ring features an overall outer diameter of 22mm, a central 7mm through hollow bore, and 4 independent conductive circuits. Its integrated flangeless miniature cylindrical design is purpose-built for narrow medical cavities, with multiple features tailored to medical device R&D needs:

Hollow Through-Hole Integrated Design, Compatible with Optical Paths and Drive Shaft Integration

The 7mm central through-hole allows direct passage for fiber optic ducts and micro drive shafts, enabling coaxial layout of optical and electrical circuits. In endoscopes and optical inspection probes, this eliminates the need for separate wiring channels, significantly reducing the overall probe outer diameter, making medical devices slimmer and more portable while improving patient examination comfort.

Miniature Compact Body, Fits Narrow Medical Cavities

The flangeless cylindrical body with a compact footprint can be embedded into the tight spaces of handheld detectors and micro diagnostic probe heads without adding extra housing volume, aligning with the trend toward lightweight and miniaturized medical devices. Color-coded independent lead wires at both ends facilitate clear circuit differentiation during assembly, reducing wiring errors.

4 Independent Isolated Circuits, Simultaneous Image and Power Transmission Without Interference

The 4 mutually insulated conductive loops can flexibly allocate functional lines: two circuits for micro imaging lens power supply, and two for high-definition image sensor signal transmission. The internal precious metal brush-contact structure ensures extremely low rotational contact resistance, with no signal glitches, image snow, or power fluctuations during continuous device rotation, guaranteeing that physicians receive clear, uninterrupted diagnostic imaging in real time.

Eco-Friendly Compliant Materials, Meeting Medical Safety Standards

The product holds ROHS environmental certification and CE safety certification, with full QC inspection upon shipment. It contains no heavy metals exceeding limits and no irritating toxic substances. The materials are safe and non-toxic, compatible with medical disinfection environment supporting equipment, and meet compliance requirements for medical device exports both domestically and internationally.

360° Unlimited Rotation, Eliminating Wire Twisting and Breakage

Traditional rotary probes use flexible flat cables, which are prone to twisting and internal copper wire breakage after repeated rotation, leading to high equipment failure rates. The ACN22T7-04-A slip ring enables permanent conduction between rotor and stator, allowing devices to rotate reciprocally without restriction, fundamentally preventing wire abrasion and breakage, and significantly reducing post-market maintenance frequency for medical equipment.

II. Core Medical Device Application Scenarios

Scenario 1: Medical Micro Endoscope Rotary Probes

ENT endoscopes and gynecological micro-endoscopic diagnostic equipment require 360° rotational scanning of lesions at the probe tip, with internal routing needed for both fiber optic light transmission and imaging sensor wiring.

By passing the drive shaft and fiber optic through the slip ring's 7mm hollow bore, the 4 circuits respectively handle lens power supply and high-definition image signal transmission. During probe rotation, the image remains stable without stuttering or black screens, while the slim body reduces patient discomfort. The slip ring's miniature dimensions fit perfectly within the probe handle, keeping the overall device structure simple and compact.

Scenario 2: Skin Imaging Diagnostic Rotary Analyzers

Aesthetic skin detectors and dermatological imaging devices require multi-angle rotation of the lens module to capture layered skin images.

The narrow instrument cavities can hardly accommodate conventional large-size slip rings. With an outer diameter of only 22mm, the ACN22T7-04-A can be directly embedded into the rotating lens base. Its hollow structure accommodates the lens rotation spindle, continuously and stably transmitting imaging data without signal loss during prolonged testing cycles. ROHS-compliant materials make it suitable for long-term use in aesthetic and medical institutions.

Scenario 3: Minimally Invasive Diagnostic and Therapeutic Rotary Instruments

Small minimally invasive auxiliary rotary operating heads and dental panoramic rotary imaging devices have extremely limited internal space while requiring simultaneous transmission of control signals and low-voltage power.

The slip ring's 4 isolated independent circuits keep power and signals interference-free, maintaining stable conductive performance under low-speed, multi-angle reciprocating rotation. The integrated sealed housing resists daily medical alcohol wipe disinfection, preventing aging and leakage to ensure safe diagnostic and therapeutic procedures.

Scenario 4: Portable Medical Rotary Inspection Pan-Tilts

Portable fundus inspection pan-tilts and mobile vehicle-mounted compact medical imaging devices pursue lightweight and portability, requiring continuous pan-tilt rotation to adjust shooting angles.

The micro hollow slip ring requires no complex mounting brackets and can be directly sleeved onto the pan-tilt spindle, eliminating redundant wiring structures and reducing overall device weight. The equipment can rotate continuously without manual cable resetting, improving consultation and outpatient examination efficiency.

III. Summary of Selection Advantages for Medical Devices

Compared to solid-shaft slip rings and large flanged slip rings, the ACN22T7-04-A micro hollow conductive slip ring offers distinct advantages tailored to the medical industry: hollow coaxial layout simplifies mechanical structures, miniature dimensions fit narrow medical cavities, precious metal contacts ensure stable high-definition image transmission, and eco-friendly compliant materials meet medical safety standards.

For small and medium-sized rotary imaging and diagnostic medical devices, the 4-circuit configuration fully covers low-voltage power and sensor signal transmission needs. It serves as a core standard component for failure reduction and miniaturization upgrades in endoscopes, skin detectors, minimally invasive diagnostic instruments, and other equipment, while supporting batch production and export matching for medical device manufacturers both domestically and internationally.

The stability of medical equipment directly affects diagnostic outcomes, leaving no room for compromise in the conductive solutions for rotating mechanisms. The CENO ACN22T7-04-A micro hollow slip ring, with its triple advantages in size, performance, and compliance, precisely matches the development requirements of various small and medium-sized medical rotary devices, providing stable and reliable continuous-rotation conductive capability to safeguard precision medical imaging and diagnostic equipment.
