Description

Ear-nose-throat department takes out tweezers with duct foreign matter

Technical Field

The utility model belongs to the technical field of medical instruments, and particularly relates to ear canal foreign body taking-out forceps for an ear-nose-throat department.

Background

Foreign matters existing in the external auditory canal are common diseases of the ear-nose-throat department, the foreign matters are generally clamped by tweezers, the common tweezers are single in function and difficult to clamp the foreign matters in the auditory canal, and particularly after the round foreign matters enter the auditory canal, the common flat-mouth tweezers are difficult to clamp and take out the foreign matters, so that the difficulty in the operation of taking out the foreign matters in the whole auditory canal is high; and the position of the foreign matter in the duct can't be seen clearly when the foreign matter is at the dark position in the duct, when using ordinary tweezers to carry out the foreign matter clamp and get, the operation is comparatively inconvenient.

Therefore, there is a need to provide a new ear canal foreign body removing forceps for otolaryngology to solve the above technical problems.

SUMMERY OF THE UTILITY MODEL

The present invention has been made to solve the above problems, and an object of the present invention is to provide ear canal foreign body removing forceps for otolaryngological department.

The utility model realizes the purpose through the following technical scheme:

the forceps for taking out foreign bodies in the auditory meatus for the otolaryngological department comprise a tube body, a slide bar is arranged in the tube body in a sliding mode, the top end of the slide bar extends out of the tube body and is provided with a pressing head, a spring is sleeved on the slide bar, and two ends of the spring are connected with the pressing head and the tube body respectively;

the pipe body is annularly provided with three chucks, the chucks are rotationally connected with the pipe body, one end of each chuck is provided with a gear, the sliding rod is provided with three racks, and the racks are meshed with the corresponding gears;

a visual system is arranged in the tube body.

As a further optimization scheme of the utility model, three notches are annularly formed in the bottom end of the pipe body, the gear is rotatably installed in the notches, and the bottom end of the chuck extends out of the notches.

As a further optimization scheme of the utility model, a sliding rail is fixedly arranged in the pipe body, and a sliding block is arranged on the sliding rail and is in sliding connection with the sliding rail.

As a further optimization scheme of the utility model, the visual system comprises a mounting ring, the mounting ring is fixedly mounted in the tube body through a support, and a camera and a lighting lamp strip are arranged on the mounting ring.

As a further optimization scheme of the utility model, handles are arranged on two sides of the pipe body, and finger grooves are formed in the handles.

The utility model has the beneficial effects that:

the utility model can clamp and take out foreign matters in the circular external auditory canal by the three clamping heads which are annularly arranged; the hand operation in a push-and-release mode is adopted, and compared with the hand operation in a pinch mode adopted when common tweezers are used, the hand operation is easier when the tweezers are used for a long time; the visual system can be used for observing the condition of foreign matters in the auditory canal in real time, so that the work is more accurate and accidental injury is avoided.
