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, treatment for 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, to remove, block, recover the unobstructed of blood flow, but this operation is more complicated, and slower, certainly will also increase the time of blood extracorporeal circulation, so also to patient, bring more adverse effect, 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, by conduit, metal by spiral lamination groove soft bar, drill bit, micro machine and the rotating shaft thereof slightly thinner than conduit diameter, formed.And for example at the < < 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 object of the present invention is to provide and use 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, the present invention has adopted following technical scheme:
A 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 of employing 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 the present invention, guiding area with metal probe is guided through expansion regions, working area the stenosis of ventricular outflow tract, then first opens 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, with dredge, leaves ventricular outflow tract; Thereby realized the dredging operation of ventricular outflow tract stenosis.
As of the present invention, further illustrate, described peeling knife is arranged in the working area tube wall of hollow.
As of the present invention, further illustrate, 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 of the blade formation of each longitudinal knife is matched mutually with the crooked radian of peeling knife.Design longitudinal knife, can effectively cut off/cut apart by thickening tissue like this, the excision resistance of reduction peeling knife, and the also seriality of cut staple ring, and can more efficiently excision thicken tissue.
As of the present invention, further illustrate, 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, 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, by the peeling knife operating means on rotary manipulation control zone, 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 rotary manipulation control zone, open peeling knife, stenosis is thickened to cutting tissue, the cut tissue that thickens drops in working area, with dredge, leave ventricular outflow tract, thereby reach the object of dredging ventricular outflow tract.
The making material of each region parts of dredge of the present invention 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 invention:
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. in working area, be provided with longitudinal knife and peeling knife, collocation is used, and first with longitudinal knife, will thicken tissue dissection, cut-out, and then excise with peeling knife, and allow the cut tissue that thickens getting off drop in working area, and with dredge, leave ventricular outflow tract, reach the object of dredging ventricular outflow tract.
3. the expansion regions of conical structure is set, can to efferent tract, expands 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.
