Electrotome device

Abstract

The application discloses an electrotome device. The electrotome device comprises a sheathing canal, a hand shank and a first electrode, wherein the hand shank is connected with the near end of the sheathing canal, and the first electrode is connected with the far end of the sheathing canal, and the electrotome device is characterized in that the first electrode is of a tubular structure; the farend side of the first electrode in the axial direction is a cutting operation part; the near end side of the first electrode in the axial direction is a connecting part fixed to the sheathing canal; and the electrotome device further comprises a cold anchor head and a conveying pipe, wherein the interior of the cold anchor head is provided with a heat exchange cavity; the conveying pipe communicates with the heat exchange cavity, and is used for conveying a cooling medium to the cold anchor head so as to adjust the temperature of the cold anchor head; the conveying pipe defines a threading path; and the sheathing canal is glidingly arranged on the conveying pipe in a sleeving manner and can move to the far end along the threading path. According to the technical scheme, the electrotome device has the advantages that localization is accurate, treatment means are diversified, the treatment process is controllable, the treatment effect is good, and a lesion is not easy to relapse.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an electric knife device. Background technique [0002] At present, lung diseases have a great impact on people's production and life, especially chronic obstructive pulmonary disease (COPD) and pulmonary bulla (pulmonary bulla). Chronic obstructive pulmonary disease (COPD) includes chronic bronchitis and emphysema. COPD is often characterized by airflow obstruction, particularly limiting the patient's ventilation during exhalation. Patients with chronic bronchitis have a chronic cough with sputum production leading to expiratory obstruction. In patients with emphysema, destruction of the lung parenchyma can lead to loss of elastic recoil, reduced airway extent, expiratory obstruction, and coughing. Pulmonary bulla (also known as pulmonary bulla) refers to the air-containing cavity formed in the lung tissue due to the increase of pressure in the alveolar cavity due to various ...

Problems solved by technology

[0006] The inventor found that when the existing electric knife for the lungs is working, the existing radiofrequency ablation operation cannot effectively judge the exact position of the front end electrode of the radiofrequency ablation catheter even under the guidance of B-ultrasound or CT

CT images are a limited number of cross-sectional images obtained by X-ray scanning. At certain angles, it seems that the front-end electrode is placed on the target site, but the actual position may be wrong, and it is only overlapping in the projection direction. Therefore, the front-end The position of the electrode is difficult to judge, and the positioning accuracy is not enough

[0007] In some treatment processes, it may be necessary to pull the lesion or surrounding tissue, which is generally not possible in the solutions of related technologies

Because the treatment method is relatively single, the existing treatment methods have the problem that after the blockage is opened, the lesion area will be blocked again after the operation, and the treatment effect is not good.
