Abstract
An eardrum pipe arranging instrument belongs to a medical instrument, is used for arranging a vent pipe on the eardrum and aims at overcoming the defects of high operation difficulty and poor precision in the existing arrangement process. The eardrum pipe arranging instrument comprises an inner core pipe and an outer cannula sheathed on the inner core pipe, wherein the rear end of the outer cannula is provided with a finger grip handle which is used when the pipe arranging instrument is held by a hand; the front end of the inner core pipe is provided with an edge; the rear end of the inner core pipe is provided with a push handle; the push handle or the rear end of the inner core pipe is provided with a connector for connecting the inner core pipe with an aspirator; a compression spring is arranged between the push handle and the finger grisp handle; and the front end of the inner core pipe can extend out of the front end of the outer cannula when the spring is compressed. Both the inner core pipe and the outer cannula consist of a front straight line segment and a rear straight line segment which are parallel to each other and not in the same straight line; the outer cannula between the two straight line segments is a semi-side pipe or a groove opened at one side which allow the inner core to be shifted out. The benefits are as follows: when the eardrum pipe arranging instrument is used for arranging the vent pipe on the eardrum, the eardrum is cut open, the secretion is aspirated out and the pipe arranging process is fully completed by the eardrum pipe arranging instrument; and the eardrum pipe arranging instrument is simple and fast to operate, high in precision and easy to succeed at a time.
Description
Technical field
The invention belongs to medical instruments field, be specifically related on ear drum membrane, place the hand device of drainage tube.
Background technology
Secretory otitis media is ENT dept.'s common disease.Be because of salpingian dysfunction, causing transmission deafness and hydrotympanum is the middle ear nonsuppurative inflammation disease of principal character.Formed middle ear effusion is serosity juice or transudate, or be mucus.Improve the MEV drain, removing middle ear effusion and etiological treatment is the Therapeutic Principle of this disease.If active treatment not, the time is long slightly, and it is gelatin that hydrops can become.Cause the tympanum adhesion, auditory dysesthesia.The general therapeutic method is: the ill initial stage is adopted the method drain of auripuncture.Do not feel any better more than four times if puncture, then considered is put the governance treatment on tympanum.The method of in the past on tympanum, placing breather is: hold scalpel earlier at the tympanum upper cut by the doctor, use tweezers clamping breather then, it is sent into auditory meatus, be placed on diaphragm-operated incision.Aforementioned operation process since in the auditory meatus space narrow and small, inconvenience is observed, the breather volume is small, is difficult to clamping, operate difficultly, operating time length, precision are poor.
Summary of the invention
The purpose of this invention is to provide a kind of tube adapter for drum membrane device, be used for the placement of breather on tympanum, the operation easier that overcomes existing put procedure existence is big, and operating time is long, the deficiency of precision difference.
Tube adapter for drum membrane device of the present invention is made up of inner core tube, the trocar sheath that is enclosed within on the inner core tube; Fingers handle when there is hand-held tube placing device the trocar sheath rear end; The inner core tube front end has cutting edge, rear end that the pushing handle is arranged; At the joint that pushes on the handle or the inner core tube rear end has inner core tube to link to each other with suction pump, between pushing handle and the grip shank compression spring is arranged, the inner core tube front end can stretch out the trocar sheath front end when spring is compressed.More than be basic scheme of the present invention.
For eliminating the influence that finger is observed the duty of the tube placing device front end that gos deep into auditory meatus; The inner core tube of tube placing device of the present invention and trocar sheath are formed by the forward and backward two sections straightways that parallel on same straight line not, and the trocar sheath between two straightways is the half side pipe that can allow inner core tube and shift out or the groove of a side opening.Perhaps between forward and backward straightway, connect the connecting rod that is separated with inner core tube, there is the strip gab that allows inner core tube to move at the position that extends radially out inner core tube outside on the sleeve pipe.
Method for using of the present invention is: hold tube placing device with forefinger and middle finger, thumb is pressed the pushing handle, and the inner core tube front end stretches out trocar sheath; Breather on the inner core tube front end sleeve, after the tube placing device front end is sent into auditory meatus, inner core tube is carried breather and is penetrated tympanum together; After the sucking-off hydrops, thumb loosens the pushing handle, and inner core tube is retreated; Breather is stayed on the tympanum, withdraws from tube placing device, accomplishes operation.
Good effect of the present invention is: use the present invention on tympanum, to place breather; With in the past elder generation at the tympanum upper cut; The reuse tweezers are compared the modus operandi that small drainage tube is placed on the tympanum otch; With tympanum incision, sucking-off secretions, put the pipe process and accomplish by tube placing device entirely, easy and simple to handle, quick, precision is high, is easy to once success.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
The specific embodiment
Consult accompanying drawing; Tube adapter for drum membrane device of the present invention comprises inner core tube 1, is enclosed within the trocar sheath 2 on the inner core tube; Middle finger and forefinger grip shank 3 when there is hand-held tube placing device the rear end of trocar sheath 2, there is thumb press handle 4 the inner core tube rear end, the joint 5 that on the thumb press handle, has inner core tube to link to each other with aspirator; Compression spring 6 is arranged between thumb press handle and the grip shank, and inner core tube 1 front end has the cutting edge that is same as the injection needle point.The inner core tube front end can stretch out trocar sheath 2 front ends when spring 6 is compressed.Inner core tube and trocar sheath be not by forming at same straight line and the leading portion a that is parallel to each other and back segment c, and one section of sloping portion b section trocar sheath and c section trocar sheath and b section trocar sheath cohesive end is removed half on radially and forms half side tubular construction between two sections.
Claims (2)
