A bronchoscopic biopsy forceps with adjustable working position

Abstract

The invention discloses a bronchoscopic biopsy forceps with adjustable working position, which comprises a handle, a catheter, a steel rope, a forceps body, an angle adjustment device and a forceps body control device, and the angle adjustment device includes: a push handle assembly and a rotary joint; The pull ring, the push handle assembly is installed in the cylindrical inner cavity of the handle, the handle connection end of the steel wire is installed on the push handle assembly, and is connected with the push handle assembly in rotation, and the push handle assembly restricts the handle connector end of the steel wire. position; the clamp body control device is connected with the clamp body, and the pull ring is connected by a steel wire to control the gripping action of the clamp body; The joint is connected with the push handle assembly, and the push handle assembly is pushed along the strip hole of the handle, so that the rotary joint drives the forceps body to rotate 360 ​​degrees to realize direction adjustment; it is easy to control and increases the success rate of biopsy; it solves the problems existing in the prior art It is difficult to control the direction of forceps tissue.

Description

technical field [0001] The invention relates to the technical field of biopsy forceps, in particular to a biopsy forceps with adjustable working direction and position used in surgical treatment. Background technique [0002] At present, lung and airway diseases, such as tumors, interstitial lung diseases, granulomatous diseases, and some infectious diseases need to be diagnosed by bronchoscopic biopsy, which is the most commonly used inspection item. [0003] Existing tracheoscopic biopsy forceps guide the doctor to operate the biopsy forceps to carry out biopsy and tissue removal to the trachea and bronchial lumen through the bronchoscope camera. Because the tracheal wall is very smooth, the lesion tissue is usually small. If the clamping angle is not appropriate, the traditional biopsy forceps will easily slip when clamping the tissue. At the same time, the soft wire inserted by the traditional biopsy forceps is difficult to control the direction inside the bronchus, and...

AI Technical Summary

Problems solved by technology

Because the tracheal wall is very smooth, the lesion tissue is usually small. If the clamping angle is not appropriate, the traditional biopsy forceps are easy to slip when clamping the tissue

At the same time, the soft wire inserted by the traditional biopsy forceps is difficult to control the direction inside the bronchus, and the operation requirements are high. It is easy to fail when the forceps are used to extract tissue. It is necessary to pull out the biopsy forceps many times to adjust the angle of the biopsy forceps and reinsert it into the bronchoscope to obtain it smoothly. diseased tissue

On the one hand, the operation is difficult, and the treatment time is forced to be extended; on the other hand, it increases the pain of the patient during the treatment process.
