Embodiment 2

[0031] A ventricular outflow tract dredger, mainly divided into a guide area 1, an expansion area 2, a work area 3 and an operation control area 4; wherein, the guide area 1 is a steerable rod provided with a metal probe 7; the The expansion area 2 described above is an area adopting a conical structural shape, one end of the cone is connected to the guide area 1, and the other end is connected to the working area 3; A rotary cutter 6 and a longitudinal cutter 5 are provided inside; the rotary cutter 6 is set close to the inner side of the pipe wall of the working area 3; the operation control area 4 is provided with a rotary cutter operating device 8, and the rotary cutter The knife operating device 8 is rigidly connected with the rotary cutter 6 to control the rotary cutter 6 to be retracted or opened.

[0032] The slitting knives 5 whose lower end is fixedly installed in the working area 3 are provided with several, and their blades extend to the position of the circumferen...

Embodiment 3

[0035] Such as Figure 5 , 6 As shown, the difference between this embodiment and Embodiment 2 is that one end of the slitting knife 5 extends into the expansion area 2 as an installation end, and is fixedly installed in the expansion area 2, and the other end of the slitting knife 5 It is the blade end, which is set in the working area 3.

[0036] The ventricular outflow tract dredger of the above embodiments can conveniently, quickly, simply and safely detect and dredge the ventricular outflow tract, and easily complete the dredging of the stenosis of the ventricular outflow tract.

Abstract

The invention discloses a dredger for a ventricular outflow tract. The dredger is mainly divided into a guiding area, an expanding area, a working area and an operating control area, wherein the guiding area is a steerable rod provided with a metal probe; the expanding area is of a conical structural shape, one end of the expanding area is connected with the guiding area, and the other end of the expanding area is connected with the working area; the working area is the working platform of the dredger for the ventricular outflow tract, and a rotary cutter and a longitudinal cutter are arranged in the working area; the rotary cutter is closely attached to the inner side of the pipe wall of the working area; the operating control area is provided with a rotary cutter operating device, and the rotary cutter operating device is in rigid connection with the rotary cutter and controls the rotary cutter to be folded or unfolded. The dredger can be conveniently, quickly, easily and safely used for probing and dredging the ventricular outflow tract. Therefore, dredging of the narrow ventricular outflow tract can be easily completed.

Description

technical field [0001] The invention relates to a medical device, in particular to a device for dredging the ventricle outflow tract in the hands of cardiac surgeons. Background technique [0002] At present, for the treatment of congenital heart disease with narrow outflow tract, there is only surgery. In the operation, it is necessary to manually trim the thickened tissue of the outflow tract, cut off and resect the fibrous ring, and dredge it to an appropriate width in order to relieve the obstruction and restore blood circulation. However, this operation is more complicated and slower, which will inevitably increase the time of extracorporeal circulation of blood, which will also bring more adverse effects to the patient. At the same time, this unblocking technique also makes the operation more difficult. Although people have also carried out some researches on the dredging apparatus of human blood vessels, as the Chinese patent application number is 97232301.5, a kind o...
