Two-in-one ultrasonic Doppler high-frequency electrotome

Abstract

The invention discloses a two-in-one ultrasonic Doppler high-frequency electrotome. The two-in-one electrotome comprises a Doppler ultrasonic scanning probe and a high-frequency electrotome and can penetrate through a biopsy duct of an endoscope. The two-in-one electrotome is scientific and reasonable in structure and safe and convenient to use. The two-in-one Doppler ultrasonic high-frequency electrotome can be flexibly switched in different modes according to requirements. In a working mode of the Doppler ultrasonic scanning probe, the two-in-one electrotome can scan whether deep tissue in an operation area has potential blood vessels or not, so that safety guarantee is provided for operation treatment, and the bleeding risk is reduced; and in a working mode of the high-frequency electrotome, the two-in-one electrotome can perform microscopic minimally invasive treatment on the detected vascular-free lesion area, so that the operation is more efficient, and the two-in-one electrotomeis safer and more reliable to use.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a two-in-one ultrasonic Doppler high-frequency electrosurgical knife. Background technique [0002] Flexible endoscopic treatment technologies such as ESD and NOTES are currently widely used technologies, which have solved many clinical problems and made great progress in minimally invasive surgery under endoscopy, especially the use of various endoscopic surgical instruments Make various endoscopic operations more mature, efficient and safe. However, bleeding is the most important problem in endoscopic treatment, which may cause fatal danger to patients. Therefore, how to pre-judge or prevent bleeding and avoid damage to large blood vessels is of great significance. [0003] Various minimally invasive surgical instrument knives (such as: IT, hook knife, dual knife, etc.) often used in the existing endoscopic treatment can effectively remove and treat various lesions, bu...

However, bleeding is the most important problem in endoscopic treatment, which may cause fatal danger to patients. Therefore, how to pre-judge or prevent bleeding and avoid damage to large blood vessels is of great significance

[0003] Various minimally invasive surgical instrument knives (such as: IT, hook knife, dual knife, etc.) often used in the existing endoscopic treatment can effectively remove and treat various lesions, but they do not have the ability to detect potential blood vessels in the tissue. Therefore, it will increase the risk and difficulty of surgery, so there is an urgent need for a device that can detect potential blood vessels in the surgical area under the endoscope to solve the above problems
