Description
Technical field
This utility model 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 in operation, need tissue that manual pruning efferent tract thickens and cut-out, excision fibrous ring, dredge to suitable width, block, recover the unobstructed of blood flow to remove, but this operation is more complicated, and slower, certainly will also increase the time of blood extracorporeal circulation, 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 to disclose a kind of human canal deroppilation apparatus, formed by conduit, the soft bar of the metal by spiral lamination groove, drill bit, micro machine and the rotating shaft thereof 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 concrete actual technical scheme above, or its technical scheme is not suitable for the dredging of ventricular outflow tract.
Summary of the invention
The purpose of this utility model is to provide and uses in a kind of surgical operation there is the congenital heart disease patients that efferent tract is narrow, simple in structure, easy to operate, safe and reliable ventricular outflow tract dredge.
To achieve these goals, this utility model has adopted following technical scheme:
A kind of ventricular outflow tract dredge, 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 that adopts 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 ventricular outflow tract dredge, and in working area, is provided with peeling knife and longitudinal knife; Described peeling knife is close to tube wall inner side, 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 this utility model, with the guiding area of metal probe, expansion regions, working area are guided through to 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 adopt peeling knife to excise it; Meanwhile, the tissue excising drops in working area, leaves ventricular outflow tract with dredge; Thereby realize the dredging operation of ventricular outflow tract stenosis.
Further illustrate as of the present utility model, described peeling knife is arranged in the working area tube wall of hollow.
Further illustrate as of the present utility model, the longitudinal knife in described working area is provided with some, and their blade extends to respectively the position of working area tube wall circumference, and the curve that the blade of each longitudinal knife is formed matches mutually with the crooked radian of peeling knife.Design longitudinal knife, can effectively cut off/cut apart thickening tissue like this, reduces the excision resistance of peeling knife, the also seriality of cut staple ring, and can more efficiently excision thicken tissue.
Further illustrate as of the present utility model, 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 utility model, 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 utility model, the lower end of described longitudinal knife is fixedly mounted in working area.
Operation principle: in dredge original state, peeling knife, in open mode, just covers longitudinal knife, when metal probe with can turn to guide rod that working area guiding is entered to efferent tract stenosis area, when working area is by behind stenosis area, operate the peeling knife operating means on control zone by rotation, pack up peeling knife, expose longitudinal knife, then, along the efferent tract dredge of pulling back, utilizing longitudinal knife that stenosis is thickened to tissue longitudinally cuts, pull back to suitable position, peeling knife operating means on rotation operation control zone, open peeling knife, stenosis is thickened to cutting tissue, the cut tissue that thickens drops in working area, leave ventricular outflow tract with dredge, thereby reach the object of dredging ventricular outflow tract.
The making material of the each region of dredge of the present utility model parts all adopts and meets the material of making medical apparatus and instruments standard, generally adopts rustless steel, if conditions permit also can be used the close biomedical metal materials such as titanium.
Advantage of the present utility model:
1. simple in structure, easy to operate, safe and reliable, can be sooner, more convenient, carry out ventricular outflow tract dredging operation more accurately, reduced the difficulty of this operation technique.
2. be provided with longitudinal knife and peeling knife in working area, collocation is used, and first will thicken tissue dissection, cut-out with longitudinal knife, and then excise with peeling knife, and allow the cut tissue that thickens getting off drop in working area, and 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 dredge operation, also done one's utmost to avoid the expansion injury of working area to efferent tract.
