A kind of cathode inner-rotary type Pacemaker implantation p-wireTechnical field
The present invention relates to a kind of medical instruments, and in particular to a kind of cathode inner-rotary type Pacemaker implantation p-wire.
Background technique
Artificial heart plays arm device, because it can issue regular electric pulse, heart can be made to keep bounce, be widely used in curingTreatment field.Pacemaker, pacing electrode wire and program control instrument constitute pacing system, and wherein pacemaker and pacing electrode wire pass throughOperation implantation human body.
3830 pacing electrode wire of Medtronic company SelectSecure, is a kind of solid core electrode cable, is conveyingUnder conduit helps, it can be used for any part in the chambers of the heart and pace, be currently used primarily in Xinier reservoir and left bundle branch region paces.The electrodeConducting wire one end is electrode tip, and for connecting pacemaker, the other end is screw terminal, for being implanted into heart of patient, electrode tip and screw-inEnd is equipped with cathode and anode.Since the electrode tip anode is cyclic structure, also known as anode ring.Patient passes through rotationThe crust of 3830 pacing electrode wires drives whole electrode cable rotation, so that the screw terminal of 3830 pacing electrode wires be plantedEnter in heart of patient.
During surgery, screw terminal is screwed into process and needs to monitor pace-making state at any time with monitor and Pacemaker programmer patientElectrocardiogram and electrode impedance situation of change, especially electrode are screwed into clockwise by interventricular septum right side in lower screw terminal cathode cavityLeft side process monitors particularly important.In current art, the cathode of 3830 pacing electrode wire electrode tips is fixed simultaneously by crocodile clipIt is connected to monitor by cathode test line, using patient skin as anode, is fixed by crocodile clip and passes through anode p-wire and connectIt is connected to monitor and paces program control instrument, in monitoring process, according to different situations, can choose and also press from both sides upper crocodile on anode ringFolder, and monitor and pace-making program control instrument are connected to by anode ring test line, to obtain more, more accurate data；In patientWhen rotating the crust of 3830 pacing electrode wires, one end that p-wire is fixed by crocodile clip is unable to synchronous rotary, causes the positionP-wire tangled up and knotted, therefore have to interrupt electrocardio and electrode impedance in cathode cavity and monitor, causing to be screwed into stroke can not be realWhen continue to monitor electrocardio and electrode impedance and change, however the variation of this electrocardio itself refers to that leading screw terminal is screwed into whether arrive at siteImportant evidence, existing way majority are in and " are screwed into-interrupt monitoring；Monitoring-interruption is screwed into " state, or it is being screwed into a tripAfter unclamp crocodile clip, then unlock p-wire tangled up and knotted part, then press from both sides crocodile clip again, to monitor whether to be screwed into place, soIt operates, makes troubles to patient repeatedly, and often need convolution to exit because monitoring causes screw terminal to be screwed into position not in time, give patientBring pain.
Therefore, it is necessary to a kind of novel test extended line, cathode test folder can both fix 3830 pacing electrode wires electricityExtreme cathode, and can rotate therewith.
