Spinejet water jet cutter suction system

The spinejet water jet cutting and aspirating system uses high-speed and controllable water flow as cutting tool to cut nucleus pulposus into small particles, and then sucks the nucleus pulposus particles out of the body according to the "Venturi" effect, reducing the volume, reducing the pressure and relieving the nerve compression of the intervertebral disc.

产品简介

Discectomy and aspiration

It can cut and suck out nucleus pulposus efficiently, shorten the operation time. The aseptic disposable handle of nucleus pulposus removal is controlled by power supply, and the disposable handle is set faster. It does not need to clean, check and sterilize before operation. It reduces the demand for a variety of traditional instruments. The amount of nucleus pulposus removed effectively is accurate and predictable, which can reduce the pressure of nerve root No matter the patient's age and the degree of intervertebral disc hydration, it can effectively ablate the tissue. Safe cooling and fluid based cutting function eliminate the risk of tissue thermal damage. The circular and non-invasive endoresector design reduces the risk of annulus fibrosus puncture and endplate injury. The insertion depth of 0.5cm laser marking device insertion depth indicator controls the insertion depth of the device Reduce the number of times the instrument passes through the surgical site and limit the risk of accidental nerve injury

Overview of spinejettm water jet system

The mechanism of intervertebral disc water jet is to cut nucleus pulposus into small particles by using high-speed and controllable water flow as cutting tool. According to the "Venturi" effect, the cut nucleus pulposus particles are sucked out of the body to reduce the volume, reduce the pressure and relieve the nerve compression of the intervertebral disc.

The venturi effect is also known as the venturi effect. This phenomenon is named after its discoverer, Giovanni Battista venturi. This effect means that there will be low pressure in the vicinity of high-speed gas or liquid, which will lead to adsorption.

Spinejet series products are used for spinal surgery. It is the first series of products of hydrocision liquid jet equipment. Hydrocision products use water to safely and accurately cut and suck pathological tissue within the intervertebral disc. The host machine extracts liquid from common clinical sterile liquid bottle / bag and applies pressure to it. The pressurized liquid is transported to the water jet head and ejected from the head and far end in the form of high-speed liquid jet. The liquid jet passes through the cutting gap at high speed and then is collected into the vacuum hose at the near end. Along with the liquid jet, it is pumped into the vacuum hose and the tissue cut after being introduced into the gap. The suction pipe is connected to a standard garbage container. The water jet cutter head has the characteristics of mechanical cutting.

Clinical indications

Hydrocision spinejet water jet system is an auxiliary tool for cutting and aspirating nucleus pulposus tissue of lumbar intervertebral disc.

Worldwide applications

In 2003, the spinal disc water jet developed by hydroscience company has been used in 28 countries (USA, Canada, Mexico, Argentina, Chile, Brazil, Italy, Germany, Spain, Greece, Sweden, Poland, Netherlands, South Africa, China, Taiwan, Korea, India, Russia, Ukraine, Turkey, Israel, Jordan, Saudi Arabia, and Kuwait) More than 40000 clinical cases have been treated with this technique.
