Medical equipment has always beenrepresentative of high-value products in the field of medical devices,especially devices like CT scanners. Like other industrial sectors, the medicaldevice industry also relies on the support of numerous downstream industries. JINPAT,as a specialized slip ring manufacturer, is part of the medical device industrychain and has the ability to provide corresponding slip rings for variousmedical equipment with different functions.

JINPAT has developed multiple types of sliprings for medical equipment. Apart from the large through-hole pancake sliprings with a diameter exceeding 1200mm developed for CT scanners, the rest ofthe slip rings are categorized as medium and small-sized products. Among theseproducts, the capsule series slip rings are the mainstay, with only a fewmodels belonging to the hollow shaft series. Whether capsule slip rings orhollow shaft slip rings, these products developed for medical equipment areprimarily customized models. To meet the stability requirements of medicalequipment, these slip rings use gold-to-gold contacts and have been optimizedin certain performance aspects.

In some specialized medical equipment withunique functions, centrifuges or other high-speed systems are integrated, andthe slip rings associated with these components are mostly high-speed products.Since the rotational speed of these components generally exceeds 500rpm,standard slip rings have a design speed limit of 300rpm, which is insufficientto meet the requirements. In order to address the needs of the medical industryand similar fields, JINPAT has developed the LPC/LPM-YS series of capsulestandard slip rings. This series of products has a design speed of up to2000rpm, meeting the requirements of the majority of medical or other high-endinstrument equipment available on the market.

Compared to the capsule slip rings with anouter diameter of 22mm, hollow shaft slip rings have much larger copper ringdiameters, which limits the transmission of certain special signals. However,this limitation is not significant in the field of medical equipment, as themost commonly used hollow shaft slip rings have a bore size of 12.7mm, and commonsignals in medical instruments such as USB 2.0, Ethernet, and pulse signals canbe transmitted within this bore size. Hollow shaft slip rings also have anadvantage in that the center through-hole can be utilized, and it can become anoptoelectronic integrated slip ring after installing fiber optic slip rings. Inmany slip ring cases developed by JINPAT for medical equipment, there are alsoproducts with integrated single-channel fiber optic slip rings.

With the advancement of technology, variousfunctional robots have also entered the field of medical care, such as surgicalrobots and rehabilitation robots. Many slip ring technologies in these medicalrobots come from the industrial robot field. As a leading technology providerin the industrial robot slip ring field, JINPAT naturally has the capability toprovide slip rings for medical robots. In addition to these two types ofrobots, there is also a category of endoscope-equipped medical inspectionrobots with slip rings. Some of these robots have endoscope lenses designed asfully movable structures capable of 360° rotation for viewing and illumination.The slip rings used in these endoscopes must be the LPMS ultra-miniature sliprings with a diameter of 5.5-6.5mm provided by JINPAT.
