Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, especially a kind of in Cardiac surgical procedures, for dredging the apparatus of ventricular outflow tract.
Background technology
At present, for the treatment of the narrow congenital heart disease of efferent tract, only have this approach of surgical operation, and operation in need manual pruning efferent tract to thicken tissue and cut-out, excision fibrous ring, dredge to suitable width, so that releasing is blocked, is recovered the unobstructed of blood flow, but this operation is more complicated, and comparatively slow, the time of blood extracorporeal circulation certainly will be too increased, so also bring more adverse effect to patient, this dredging technology also makes operation technique difficulty increase simultaneously.Although people have also carried out some researchs to the dredging apparatus of human vas, if Chinese Patent Application No. is 97232301.5 disclose a kind of human canal deroppilation apparatus, by conduit, the metal of spiral lamination groove soft bar, drill bit, micro machine and rotating shaft thereof be made up of slightly thinner than conduit diameter.And for example at " medical equipment information " of the 5th phase in 1996, Research Notes, 11-12 page discloses some contents of a kind of blood vessel dredging rotary cut device.But disclosed content or do not disclose the technical scheme of concrete reality above, or its technical scheme is not suitable for the dredging of ventricular outflow tract.
Summary of the invention
The object of the present invention is to provide and to use in a kind of surgical operation there is the narrow congenital heart disease patients of efferent tract, the dredger for ventricular outflow tract that structure is simple, easy to operate, safe and reliable.
To achieve these goals, present invention employs following technical scheme:
A kind of dredger for ventricular outflow tract, is mainly divided into guiding area, expansion regions, working area and operation control zone; Wherein: described guiding area be provided with metal probe can turning-bar; Described expansion regions is the region adopting conical structure shape, the connection guiding area, one end of taper, and the other end connects working area; Described working area is the work platforms of dredger for ventricular outflow tract, and is provided with peeling knife and longitudinal knife in working area; Described peeling knife is close to inside the tube wall of working area and is arranged; Described operation control zone is provided with peeling knife operating means, and described peeling knife operating means and peeling knife are rigidly connected, and controls peeling knife and packs up or open.
In the present invention, with the guiding area of metal probe, expansion regions, working area are guided through the stenosis of ventricular outflow tract, then first open longitudinal knife, toward pulling back and will thickening tissue and/or slit shearing, and be divided into some thins, then peeling knife is adopted to excise it; Meanwhile, the tissue excised drops in working area, leaves ventricular outflow tract with dredge; Thus achieve the purge operation of ventricular outflow tract stenosis.
Further illustrate as of the present invention, described peeling knife is arranged in the working area tube wall of hollow.
Further illustrate as of the present invention, the longitudinal knife in described working area is provided with some handles, and their blade extends to the position of working area tube wall circumference respectively, makes each the curve that the blade of longitudinal knife is formed to be matched mutually with the crooked radian of peeling knife.Such design longitudinal knife, effectively can cut off/segmentation by thickening tissue, reducing the excision resistance of peeling knife, the also seriality of cut staple ring, and more efficiently excision can thicken tissue.
Further illustrate as of the present invention, the installation site of described peeling knife is corresponding with the installation site of longitudinal knife, and in peeling knife open mode, peeling knife covers longitudinal knife.
As a kind of mounting means of longitudinal knife of the present invention, one end of described longitudinal knife extends in expansion regions, as installation end, and is fixedly mounted in expansion regions, and the other end of longitudinal knife is blade end, is arranged in working area.
As the another kind of mounting means of longitudinal knife of the present invention, the lower end of described longitudinal knife is fixedly mounted in working area.
Operation principle: in dredge original state, peeling knife is in open mode, just covers longitudinal knife, when metal probe and can turn to guide rod by working area guide enter efferent tract stenosis area, when working area is by behind stenosis area, by the peeling knife operating means on rotation process control zone, pack up peeling knife, expose longitudinal knife, then, to pull back dredge along efferent tract, utilize longitudinal knife stenosis to be thickened tissue longitudinally to cut, pull back to suitable position, peeling knife operating means on rotation process control zone, open peeling knife, stenosis is thickened cutting tissue, the cut tissue that thickens drops in working area, ventricular outflow tract is left with dredge, thus reach the object of dredging ventricular outflow tract.
The making material of each section components of dredge of the present invention all adopts the material meeting and make medical apparatus and instruments standard, and general employing rustless steel, if conditions permit, also can use the close biomedical metal materials such as titanium.
Advantage of the present invention:
1. structure is simple, easy to operate, safe and reliable, can sooner, more convenient, carry out ventricular outflow tract purge operation more accurately, reduce the difficulty of this operation technique.
2. be provided with longitudinal knife and peeling knife in working area, collocation uses, and first will thicken tissue dissection, cut-out with longitudinal knife, and then excise with peeling knife, and allow the cut tissue that thickens got off drop in working area, leave ventricular outflow tract with dredge, reach the object of dredging ventricular outflow tract.
3. the expansion regions of conical structure is set, can expands efferent tract gradually, make working area smoothly by behind efferent tract stenosis area, then carry out purge operation, also do one's utmost to avoid working area and the expansion of efferent tract is injured.
