Embodiment 1

[0024] A bronchoscopic electrocoagulation probe passes through the biopsy channel of the bronchoscope and connects the electrocoagulation wire and the electrode. The electrocoagulation probe includes two probes 1 which are pivotally connected; the electrocoagulation probe 1 also has Set the control line 2, the control line is composed of a bayonet 21 and a steel wire 22, the bayonet 21 controls the rotation of the two probes, the end of the steel wire 22 is connected to the control handle; the electrocoagulation probe 1 is fixed on the base, the base 3 is hollow, and the electrocoagulation Both the wire and the steel wire pass through the inner hole of the base 3 .

Embodiment 2

[0026] Such as Figure 1 ~ Figure 3 As shown, a bronchoscopic electrocoagulation probe has two probes 1, both of which are semi-cylindrical. The top of the probe 1 is used for electrocoagulation, and the bottom is used for connection. The connection part is made into a sheet for easy connection. There are holes on the outside of the connecting part of the probe, which are respectively connected to both sides of the base through the connecting piece. Each probe can rotate 0°-180° around the connection point. Four fixed points are set for the rotation angle of the coagulation probe around the connection point, which are respectively 0°, 60°, 120° and 180°. There is a slideway at the bottom of the probe connection part, the slideway is curved, and the connecting shaft 4 passes through the slideway 11 of the probe connection part to form a pivot connection. Since the outer side of the connecting part of the probe is connected to the base 3, when the connecting shaft is pulled to ...

Embodiment 3

[0028] Such as Figure 4 A bronchoscopic electrocoagulation probe is shown, the rest are the same as in embodiment 2, wherein the electrocoagulation probe also includes two connecting pieces 5, the top of the electrocoagulation probe connection part has a hole, and the two probes 1 and 1 are connected through the connector. Base 3, the electrocoagulation probe rotates around the central support point. The bottom end of the connecting part of the electrocoagulation probe is connected to the connecting piece, and the connecting piece is connected to each other to form a rhombus, and the bayonet 22 of the control line 2 is clamped to the connecting piece.

Abstract

The invention relates to the field of medical instruments, and discloses an electrocoagulation probe passing through a bronchoscope. The electrocoagulation probe passing through the bronchoscope comprises a biopsy hole channel penetrating through the bronchoscope, a connecting electrocoagulation line and an electrode. The electrocoagulation probe passing through the bronchoscope is characterized in that the electrocoagulation probe comprises two probe bodies which are in pivot connection, the electrocoagulation probe is further provided with a control cable, and the tail end of the control cable is connected with a control handle; the electrocoagulation probe is fixed on a base, the base is hollow, and the electrocoagulation line and the control cable both pass through an inner hole of the base. The electrocoagulation probe can rotate around a connecting point, the control cable moves up and down and moves to drive the connecting point to be turned to rotating movement of the probe bodies, and the effect of adjusting the angles of the probe bodies is achieved. According to the electrocoagulation probe passing through the bronchoscope, one cylindrical electrocoagulation probe is changed to be two probe bodies, the burning range can be increased, the two probe bodies are in pivot connection and can rotate around the connecting point, the rotating angles are adjusted through movement of the control cable and the connecting relations of the probe bodies, the base and the control cable, the control cable is pulled, so that opening size of the two probe bodies is adjusted, and the burning range is changed.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to an electrocoagulation probe used for penetrating a bendable bronchoscope for electrocoagulation during the treatment of benign airway stenosis. Background technique [0002] Benign airway stenosis is a common disease of the respiratory system, which can lead to respiratory failure and even life-threatening in severe cases. It is often necessary to treat the stenosis with a flexible bronchoscope. One of the currently commonly used methods is to electrocoagulate the stenosis through a flexible bronchoscope. The high-frequency current is concentrated on a point in contact with it to generate heat to the local tissue of the human body, and cauterization of the lesion can relieve airway stenosis. The operation requires a bronchoscope, a high-frequency electrocautery instrument and the corresponding electric knife, electrocoagulation probe, snare and other instruments. Durin...
