Problems solved by technology

[0003] However, existing ultrasonic endoscopes still have deficiencies, such as the overall size of the endoscopic catheter supporting ultrasound guidance is too large to enter small lumens
At the same time, the existing lens body is expensive, which limits its popularization and promotion

Embodiment 1

[0033] This embodiment provides an ultrasonic endoscope catheter, which includes an elongated flexible body, an ultrasonic probe, a probe regulating device and a connector.

[0034] An elongated flexible body has a top and a tail, and a first working channel extending between the top and tail. The first working channel is configured to slidably receive a medical instrument.

[0035] In a preferred embodiment, said flexible body is substantially cylindrical with a diameter not greater than 3mm.

[0036] In a preferred embodiment, the first working channel is substantially cylindrical with a diameter of 1-2mm and hollow inside. One end opening of the first working jaw is located at the tail of the flexible main body, and the other end opening is located at the top of the flexible main body. When in use, the top of the flexible body of the ultrasonic endoscope catheter is pushed to the vicinity of the target position that needs to be treated, so that the slender medical instrum...

Embodiment 2

[0046] This embodiment provides an endoscope system, including a display, a system host, an endoscope, and an ultrasonic endoscope catheter according to any one of Embodiment 1 of the present invention.

[0047] The display can be any form of equipment applicable in the prior art, which is used to display images acquired through the ultrasonic endoscope catheter and related interactive data information during operation.

[0048] The endoscope has an elongated shape suitable for entering the body through a hole in the human body itself or punctured, and has a second working channel extending along the elongated shape. The second working channel is configured to slidably receive the ultrasound endoscopic catheter.

[0049] The system host includes a transmitting module, a receiving module, a control processing and module image display processing module.

[0050] The transmitting module is mainly used to transmit high-voltage pulses to excite the ultrasonic probe in the catheter...

Embodiment 3

[0055]This embodiment provides a medical device navigation method using the endoscope system described in Embodiment 2 of the present invention, including the following steps:

[0056] Connect the ultrasonic endoscope catheter of the endoscope system with the host through the connector.

[0057] The ultrasonic endoscope catheter is pushed to the vicinity of the target position through the second working forceps, and an ultrasonic image of the target position is collected through an ultrasonic probe.

[0058] inserting the medical instrument into the first working channel, and tracking the position and posture of the medical instrument according to the ultrasonic image.

[0059] The observation angle of the ultrasonic probe is adjusted by the probe control device to ensure that the medical device is within the best observation range of the field of view. The operator can adjust the posture and position of the probe in real time according to the image feedback information, inse...

Abstract

The invention provides an ultrasonic endoscope catheter. The ultrasonic endoscope catheter comprises a slender flexible main body, an ultrasonic probe, a probe regulating and controlling device and a connector, wherein the slender flexible main body is provided with a top part, a tail part and a first working clamp channel extending between the top part and the tail part; the first working clamp channel is configured to slidably accommodate a medical instrument; the ultrasonic probe is arranged in the flexible main body and close to the top part, and is used for emitting ultrasonic waves and receiving reflected signals; the probe regulating and controlling device is arranged in the flexible main body, is connected with the ultrasonic probe, and is used for lifting the ultrasonic probe towards a set direction and inclining the ultrasonic probe by a certain angle; and the connector is connected to the tail part of the flexible main body, and is electrically connected with the ultrasonic probe through a cable arranged in the flexible main body. The ultrasonic endoscope catheter provided by the invention has the characteristics of small size, flexibility in operation and the like, can break through a lung lesion part far away from a segment bronchus which cannot be reached by the conventional ultrasonic endoscope, and realizes puncture and minimally invasive treatment under real-time ultrasonic guidance of lung peripheral lesions.

Description

technical field [0001] The invention relates to an endoscopic catheter, in particular to a small-sized ultrasonic-guided ultrasonic endoscopic catheter, which belongs to the technical field of medical devices for diagnosis. Background technique [0002] Endoscopic ultrasonography is an interventional technology that combines endoscopy with ultrasonography, such as ultrasonic gastroscope, ultrasonic bronchoscope, etc. It is a technology that is constantly improving and expanding its functions. Ultrasound endoscope fills the gaps of some special indications that cannot be covered by ordinary endoscope, body surface ultrasound and CT, and is being increasingly widely used in clinic due to its advantages of high resolution and good real-time performance. Especially in recent years, positive progress has been made in needle biopsy under endoscopic ultrasonography, tumor radiofrequency, photodynamic and laser therapy. [0003] However, existing ultrasonic endoscopes still have de...
