Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described, and embodiments of the present invention include but not limited to the following example.
Embodiment
As shown in figures 1-4, a kind of visual optical fiber foley's tube, comprise inflatable balloon 1, one end is communicated with inflatable balloon and for gas being passed into the trocar sheath 2 in inflatable balloon, to be arranged in trocar sheath and can the fibre-optic catheter 3 of movement in trocar sheath, and to be arranged at trocar sheath other end outside and the optical fiber operating handle 4 be connected with fibre-optic catheter; The end, one end that described trocar sheath is connected with inflatable balloon is positioned at inflatable balloon.By device of the present invention, the orientation of visiting focus accurately can be known; Mainly by inflatable balloon, the blood in organ (such as heart) or other liquid are squeezed, with inflatable balloon, focus (such as abnormal structure) is covered, completely focus and liquid or blood are separated, by fibre-optic catheter, undertaken of focus is visited again, thus locate accurately, facilitate the operation in later stage.Simultaneously the present invention also can carry out visual guiding to some interventional procedures, and carries out observations evaluation to therapeutic effect and the complication that may exist and (cause thrombosis as caused neointimal lesion after catheter ablation; The complication such as ablation of excess causes cardiac perforation, esophagus atrium fistula, and adopt the present invention can carry out observation evaluation to above-mentioned condition).
What deserves to be explained is that optical fiber operating handle of the present invention can regulate direction and the angle of fibre-optic catheter head end to a certain extent.
In order to understanding focus situation clearly, on described inflatable balloon, just externally the position of cannula tip is provided with scale 5.By arranging scale on inflatable balloon, can measure the size of focus, size.Mainly covered by inflatable balloon, scale is also just measured with the outside edge contacts of focus; Preferred as one, inflatable balloon is provided with longitudinal scale and horizontal scale, thus the size of focus can be determined accurately.
Conveniently for inflatable balloon carries out inflating, exitting, described optical fiber operating handle is positioned at the other end of trocar sheath; Described trocar sheath sidewall is connected with arm, and this arm is provided with valve 6.By arranging special arm, and valve, can inflate inflatable balloon at any time, exit, thus guarantee the operation that the present invention is convenient.Certainly also at arm, sealing cap can be set away from the end, one end of trocar sheath, thus further guarantee that inflatable balloon is air tight.
What deserves to be explained is, described fibre-optic catheter comprises the imaging fiber unit being positioned at trocar sheath, and the image monitor unit be connected with imaging fiber unit and light source control unit.Certainly, fibre-optic catheter of the present invention can adopt existing equipment, is directly buying on the market.
In order to improve practicality of the present invention, so be also provided with the ultrasonic transducer 8 be socketed on trocar sheath outer wall in described inflatable balloon, particularly this ultrasonic transducer is loop configuration, in use, ultrasound wave to be formed in the front end of inflatable balloon after reflecting via the part side of trocar sheath connecting place (namely with) of arc bottom inflatable balloon and focuses on; Ultrasonic energy can produce heat energy and melt local organization after focusing on.Thus make the present invention both can carry out observation measurement, can also treat.But when treating, being first inflate in inflatable balloon, thus being convenient to fibre-optic catheter observation, measurement, location, and then inject de aerated water in inflatable balloon, being convenient to delivering ultrasound energy.
Further, described ultrasonic transducer comprises ultrasonic transmitter, with for controlling ultrasonic transducer and the external main control system be connected by cable 11 with ultrasonic transducer.The output frequency of ultrasonic transducer and energy size etc. are controlled by external main control system.Described cable and fibre-optic catheter are juxtaposed in trocar sheath.
Again further, described ultrasonic transmitter comprises the ultrasound wave driver module 9 be positioned on trocar sheath outer wall, and is socketed on the ultrasonic transducer unit 10 of ultrasound wave driver module outside.Above-mentioned ultrasound wave driver module, can according to intensity instruction and frequency instruction output ultrasonic wave command signal, and ultrasonic transducer unit is used for the instruction transformation from ultrasound wave driver module to become ultrasound wave.But ultrasonic transducer unit of the present invention by three pieces work alone and form for the transducer unit of arcuate structure, three pieces of transducer units join end to end formation annular.But ultrasound wave driver module is also set to three and transducer unit one_to_one corresponding.
In order to better realize the present invention, described inflatable balloon is made by transparent material.
According to above-described embodiment, just the present invention can be realized well.What deserves to be explained is; under prerequisite based on said structure design, for solving same technical problem, even if some making on the invention are without substantial change or polishing; the essence of the technical scheme adopted is still the same with the present invention, therefore it also should in protection scope of the present invention.
