1, straight thread Straight thread as the common standard type, thread front have 3-5 cm soft segment, there are also designed for a special purpose godet, soft long up to 15 to 20 cm, straight thread form because of the different methods of welding wire core, straight thread form and activities can be divided into fixed core core straight thread. Thread surface such as coated ptfe membrane, it is called a Teflon sheath straight thread. Straight thread USES broad, applies to the vast majority of percutaneous puncture intubation operation.
2, J security thread Godet front a J shape bending, its advantage is met the blood vessels of the bending deformation, intubation godet front end not in the blood vessel wall, which can prevent the damage blood vessels. J shape godet front end bending is divided into large, medium and decimal. Small bending is suitable for the blood vessels. Large bending can help to adjust the direction of the cannula, at the site of the bile duct to have change, can be bent with thread, insert the catheter branches in different direction. J type guide wire has fixed core, core activities, several kinds of Teflon sheath.
3, the front direction controlled wire guidance This thread is also called Deflector (Deflector), composed of a front end can be bent 180 degrees can KongDao wires and consisted of a manipulation of the handle. Thread end fixed on the handle, manipulation of the handle can make godet front straight or curved. Deflector is mainly used for intubation, PanQu artery sclerosis patients can also help with selective and super selective vascular cannula.
4, replace the catheter with guide wire catheter treatment process, often need to replace the catheter, with the help of a guide to help in the most simple and convenient. In tube thread structure and general shape the same thread, but increases to 2.6 m length.
In addition, there are some special type of thread. As the bile duct percutaneous liver puncture intubation godet, front-end for soft stainless steel wire spring, its trunk is the same as the spring diameter wire, can make the backbone to harden, have strong ability of support, help catheter customer service liver capsule and the resistance of the liver parenchyma, smoothly into the bile duct. Another thread, the front-end soft segment has a conical intumescence part, used to guide the coarser the catheter into the body. . .
