Abstract
The utility model discloses a bending-proof extension lead used in an implant-type medical system. The bending-proof extension lead comprises a plug part, one or more extension guide wires connected with one or more plug electrode wires, and a heat-shrinkable bushing used for dispensing bending stress and sleeved on a connecting part of the multiple extension guide wires and the multiple plug electrode wires. The utility model also discloses the implant-type medical system comprising the extension lead. After an implant-type medical instrument and the extension lead are implanted into the body of a patient, as the heat-shrinkable bushing covers the relatively rigid extension lead plug part and the relatively soft extension guide wire part, the stretching and bending force generated by the daily activities of the patient cannot directly act on the connection part of the extension guide wires and the plug electrode wires, and instead, the stretching and bending force is dispensed by the heat-shrinkable bushing onto the surface thereof and a hand-holding part outside the heat-shrinkable bushing. Therefore, compared with those of extension leads in the prior art, the bending antifatigue strength of the extension lead is greatly increased and the service life of the extension lead is prolonged. Moreover, the extension lead is simple in structure, simple in manufacture technology, and relatively low in manufacture cost.
