Problems solved by technology

It can be combined with the existing clinical use of endoscope or minimally invasive technology to penetrate into the internal organs of the human body, collect and collect backscattered light from biological tissues, and the balloon has good transparency and can affect the normal esophagus A certain expansion force, so it is the first choice for OCT optical probe scanning. However, ordinary dilation balloons are guided and supported by guide wires. The filling medium is generally liquid, and there is a marked developing ring on the inner tube. When filling, the inner tube will Bending, the optical probe will have problems such as incomplete imaging during the scanning process, so there is a need for improvement

Embodiment 1

[0049] Such as figure 1As shown, a balloon catheter of an OCT endoscopic scanning imaging system includes a handle 12, one interface of the handle 12 is a host interface 14, and the other interface is a ventilation interface 13; the double-lumen tube 11 can allow the OCT optical probe to pass through; Balloon 10, the front end of the balloon 10 is blocked and there is a scale on the balloon; the inner tube 9, the concentricity of the inner tube 9 and the balloon 10 deviates no more than 200 microns under 3 atmospheres; the soft head 8 is a solid structure , wherein one end of the double-lumen tube 11 is connected to the handle 12, the other end is connected to the inner tube 9 and one end of the balloon 10, the other end of the balloon 10 is connected to the inner tube 9 and the soft head 8, and the double-lumen tube 11 is glued by UV The glue is connected with the handle 12, and other parts are all connected by welding.

[0050] The material of the handle 12 is polycarbonate...

Embodiment 2

[0054] A method for using the balloon catheter as described in Example 1, the steps comprising:

[0055] 1. The endoscope enters the human body through the natural orifice of the human body.

[0056] 2. Insert the balloon catheter with the OCT fiber optic probe into the forceps channel of the endoscope.

[0057] 3. Push the balloon to the part to be scanned.

[0058] 4. Tighten the connector of the handle guide wire chamber and the connector on the OCT device, and tighten the inflation interface and the connector of the automatic inflation pump.

[0059] 5. Click the inflation button on the device software to inflate.

[0060] 6. After inflation, click the scan button on the software to scan the image.

[0061] 7. Click the inhalation button after scanning.

[0062] 8. Withdraw the balloon catheter back into the endoscope after inhalation.

Embodiment 3

[0064] Such as figure 2 As shown, an OCT endoscopic scanning imaging system includes a frequency-sweeping laser module, an interference module, a detector module, a data acquisition module, a data processing module, an image display module, an actuator, an OCT microprobe, an inflation and deflation device, and figure 1 The balloon catheter shown, where,

[0065] The frequency-sweeping laser module includes a high-speed frequency-sweeping laser, a fiber isolator and a fiber coupler, which isolate the optical signal output from the frequency-sweeping laser from the subsequent optical path, preventing the optical signal returned by the subsequent optical path from interfering with the normal operation of the laser; the interference module A fiber-optic Mach-Zehnder interferometer (MZI) or a fiber-optic Michelson interferometer structure can be used. The Mach-Zehnder interferometer structure is mainly composed of two fiber couplers, two fiber circulators and two fiber polarizati...

Abstract

The invention relates to the technical field of medical instruments, and provides a balloon catheter which is matched with an endoscope and an OCT (optical coherence tomography) optical detector for use, an OCT imaging system, and a use method. The balloon catheter comprises a handle, a dual-cavity pipe, a balloon, an inner pipe, a soft head and the like; the use pressure of the balloon catheter is 3 separate atmospheric pressure; damage to a normal gullet is not caused under lower pressure, at the same time concentricity of the inner pipe and the balloon is ensured and optic imaging is facilitated.

Description

technical field [0001] The invention relates to a balloon catheter, especially a balloon catheter used in optical coherence tomography, a method for using the same, and an OCT endoscopic scanning imaging system with the balloon catheter. Background technique [0002] Optical Coherence Tomography (OCT) has been widely used in the field of ophthalmology diagnosis. This technology is based on optics, electronics and computer technology science. A new imaging technology integrating many frontier disciplines, OCT has attracted people's attention due to its advantages such as high resolution and high speed imaging, and has begun to be valued and applied in the fields of biomedicine and clinical diagnosis. [0003] Compared with other imaging methods such as CT, ultrasound, and MRI, OCT has extremely high resolution. Compared with traditional laser confocal microscopes, OCT has obvious advantages in imaging depth. Most of the core technologies of traditional optical probes use opt...
