Analysis of Slip Ring Technology Features in Medical Devices with Different Functions

Slip ring technology in medical devices exhibits distinctcharacteristics based on their respective functionalities. Let's start by examining diagnostic and analytical medical devices. As a vital component within medical equipment, CT scanners represent a pinnacle of advancedtechnology. Even within the CT system, slip rings are utilized. To validateslip ring technology in CT scanners, JINPAT has developed large-scaleseparate-structure pancake slip rings. These slip rings, such as the LPKS820-0315 model, feature a through-hole diameter of 820mm, an outer diameterof 1269mm, and integrate three 15A current paths utilizing carbon brush friction pairs. These slip rings require no regular maintenance and possess excellent resistance to shock and vibration.

Alternatively, if needed, pancake slip rings used in CT scanners can be designed as integral structures. However, due to the CT scanner's maximum rotational speed of 300rpm, the linear velocity requirement for the corresponding pancake slip ring is 20m/s. This presents a challenging task indesigning pancake slip rings for CT scanners, demanding high levels ofengineering precision and manufacturing capabilities from slip ringmanufacturers. Consequently, the distinguishing characteristics of CT sliprings can be summarized as structurally simple yet demanding high levels ofprecision in processing and design.

In the medical device market, numerous cosmetic and physiotherapy devices serve different functions. Compared to high-tech and high-value CTscanners, these devices exhibit relatively simple structures andfunctionalities. Despite their relatively lower product value, they stillrequire the utilization of slip rings. JINPAT provides several product examplesfor these medical devices with lower technological barriers, mainly focusing onthe LPC, LPM, and LPMS series products featuring fewer current paths. The capsuleslip rings from JINPAT adopt gold-to-gold friction pairs, offering compactsize, excellent electromechanical performance, and customization options tosupport various signals or other additional requirements.

In addition to medical devices with diverse functionalities, anessential equipment in the operating room is the surgical shadowless lamp. Toassist surgeons in performing better operations, many shadowless lamps aredesigned with a 360° rotation mechanism, requiring the installation of sliprings. As a pioneering slip ring manufacturer, JINPAT has specifically developed two types of slip ring structures for shadowless lamps. One type isthe plug-and-play slip ring, while the other is the separate-structure slipring. The separate-structure products utilize a combination of carbon brushesand spring contacts, with carbon brushes employed for current paths of ≥10A andspring contacts utilized for small currents or signal paths of 2A. The plug-and-play slip rings feature compact size, small installation spacerequirements, a lifespan of up to 200,000 insertions and withdrawals, andsupport for customized high-speed data signals, HD/3G-SDI signals, controlsignals, and more.
