Cardiac muscle parcel tissue even；3. in inferior caval vein feeding claw pincers type catching device etc., directly hardness pulls out electrode wires again.But by its structure
Make and limited, its electrode used therein line pulls out that apparatus structure is complicated, and especially pacemaker electrode head end due to being wrapped for a long time by cardiac muscular tissue
Wrap up in, can tear cardiac muscular tissue during pulling out, or even cause the cardiac rupture to cause death, there is unsafe factor.
The content of the invention
In order to overcome the deficiencies in the prior art, solving existing pacing lead, to pull out apparatus structure complicated, exists not
The problem of safety factor.A kind of simple and practical it is an object of the present invention to provide, operation is simple, and safe and convenient to use is new-type
Pacing lead is separated with pacemaker main frame and pulls out apparatus.
The present invention the used technical scheme that solves the above problems is：
A kind of pacing lead cutter, it is provided with：Electrode wires detachment conduit, fixing cutter, circular movable blade, drawing
Silk, fixing cutter is installed with the upper oral part of electrode wires detachment conduit, and fixing cutter is circular edge and side is formed with arc-shaped
The circular fixing cutter of through hole, coordinates circular edge to be fitted with circular movable blade on the top of fixing cutter, circular activity
Knife is for both sides are the single-blade crescent shape cutting edge elastic blades of straight flange and are fitted with the single-blade crescent shape cutting edge elastic blade other end
It is fitted with the circular movable blade of wire drawing, wire drawing is worn and is connected in the arc-shaped through hole of fixing cutter and connected with electrode wires detachment conduit cavity
To the lower mouth of electrode wires detachment conduit.
Above-mentioned pacing lead cutter, the infraoral of the electrode wires detachment conduit is fixed and is fitted with knob company
Seat, is formed with center protruding shaft on knob seated, coordinate in the center protruding shaft of knob seated and be fitted with wrapping wire knob, on wrapping wire knob
The wire drawing of the circular movable blade of winding.
Above-mentioned pacing lead cutter, is formed with the cunning for coordinating circular movable blade positioning to slide in the fixing cutter
Groove.
Above-mentioned pacing lead cutter, the outer top of the knob seated center protruding shaft be formed with gear, around
The outer top of silk knob is formed with positioning alligator, and positioning tooth pin rodent connects the gear of knob seated center protruding shaft.
Above-mentioned pacing lead cutter, the outer top of the wrapping wire knob is also formed with the knob anglec of rotation and indicates to carve
Degree.
Above-mentioned pacing lead cutter, is formed with the spiral shell of inlaid solid connection wire drawing on the excircle body of the wrapping wire knob 7
Rotation groove.
When the present invention is used, according to technical requirements and being actually needed, its operating procedure is：1. Locking stylet locks electrode；
2. application electrode separator separates the tissue with electrode adhesion；3. the electrode wires detachment of this pacing lead cutter is led again
Pipe is inserted in primary electrode line makes a gift to someone to the position of pacing lead and heart contact, tenses electrode wires, detachment conduit is come directly towards end
Close to electrode wires and myocardium contact point, the wrapping wire knob of electric rotating polar curve detachment tail end of conduit affects the drawing of circular movable blade
Silk pulls circular movable blade, mobile blade along fixing cutter slide and will with the crescent shape blade overlaying and articulation of fixing cutter
Electrode wires are blocked and integrally withdrawn from vitro, and any bad influence is not resulted in patient.
Because present invention design employs above-mentioned technical proposal, pulling out for existing pacing lead is efficiently solved
Apparatus structure is complicated, there is a problem of unsafe factor.Also show through overtesting result on trial, it have it is simple and practical,
Operation is simple, any bad influence is not caused to patient, the advantages of safe and convenient to use, it is adaptable to pacing lead point
From cut-out.
