The invention discloses an external operating handle of a medical appliance and the medical appliance, wherein the medical appliance part comprises an operating handle and a conduit system, an upper gear installing space and a lower gear installing space are formed by the division of a middle partition, a main control channel, a first sub-control channel and a second sub-control channel are arranged in the partition, a left control line and a right control line penetrate through a first gear and the first sub-control channel, a front control line and a back control line penetrate through a second gear and the second sub-control channel, and a guide wire penetrates through the main control channel and then is lead out from an arc-like channel of a guide wire operating part. The conduit system is inserted into a blood vessel from a wound; when the blood vessel has a certain degree of curvature, the direction of the conduit system is controlled by controlling a first gear ring and a second gear ring; and when the conduit system reaches a plugging position, a main control mechanism can be operated to eject a stopper at the end part of the conduit system, the stopper pushes open under the self-elasticity effect, so the stopper is accurately fixed to the plugging position, and then the conduit system is pulled out in the reverse direction.
Description
technical field [0001] Medical devices commonly used in the treatment of the cardiovascular system involve minimally invasive surgical procedures, for example, the closure of some ruptured arteries. Background technique [0002] The current medical instrument handle related to interventional treatment has a structure including a slender handle shell, a rotatable sleeve arranged around the proximal end of the handle casing, a rotatable control knob arranged around the proximal part of the sleeve, and a A slidable door is provided on the far side of the tube, and the interventional treatment point at the distal end is controlled by the handle, so as to realize the purpose of interventional treatment. [0003] However, most of the current handles are pushed through the slider structure, and the control force is relatively large. Compared with the small movement range of interventional therapy, the strength of both hands is required to control the operation process. Contents o...
