Laser optical fiber import handle

Abstract

The invention relates to the technical field of medical device auxiliary equipment, in particular to a laser optical fiber import handle. The laser optical fiber import handle comprises a handle comprising a handle body and a handle head which are connected with each other, a connecting pipe is arranged inside the handle body in an embedded mode, an optical fiber channel is arranged inside the handle head in an embedded mode, the side wall of the handle head is provided with an optical fiber import opening, the optical fiber import opening communicates with the optical fiber channel, and the optical fiber import opening is sealed by a silicone sealing plug; the end of the handle head is provided with a welding thread, the welding thread is connected with a locking nut, a rotating head sleeves the locking nut, and a sealing ring is arranged between the rotating head and the locking nut; and one end of a conduit is arranged in the rotating head in an embedded mode and communicates with the optical fiber channel. According to the laser optical fiber import handle, design with the conduit and the rotating head is adopted, thus the position of a detection optical fiber can be changed flexibly, practical application and observation are facilitated, and the function of clearing a foreign body or gas in the throat in time is further achieved.

Description

Technical field [0001] The invention relates to the technical field of medical equipment auxiliary equipment, in particular to a laser optical fiber introduction handle. Background technique [0002] The laser fiber introduction handle is an auxiliary device for safe operation of the larynx cavity. The fiber is mainly inserted into the patient’s larynx cavity through the catheter at the end of the laser fiber introduction handle for observation to facilitate the operation. However, the laser fiber introduction handle in the prior art It has the following shortcomings: the laser fiber guide tube at the end of the handle is fixed and cannot be flexibly changed. When it reaches the inside of the patient's larynx, if the observation position is found to be different, it will affect the surgical effect; in addition, if the patient is found There are foreign bodies or gas in the larynx obstructing observation, and it cannot be removed in time, which makes the operation extremely diffic...

Problems solved by technology

[0002] The laser fiber guide handle is used as an auxiliary device for laryngeal cavity safety surgery. The optical fiber mainly penetrates into the patient's laryngeal cavity through the catheter at the end of the laser fiber guide handle for observation to facilitate surgical operations. However, the laser fiber guide handle in the prior art It has the following defects: the catheter at the end of the laser fiber introduction handle is fixed and cannot be flexibly changed. When it penetrates into the patient's throat cavity, if the observation position is found to be different, it will affect the surgical effect; There are foreign objects or gas in the larynx that hinder the observation, and cannot be removed in time, making the operation extremely difficult
