The distance between the oral inlet and the vocal cords is relatively long, and the length of the injection pipeline is required to be usually more than 30 cm, so that the portability of the instrument cannot be realized. In order to be convenient to carry and shorten the length of the supporting tube in a storage state, the supporting tube is a sleeve and comprises an outer tube 10 and an inner tube 15, the inner tube 15 can slide in the outer tube 10, a locking piece is arranged between the outer tube 10 and the inner tube 15, when the rear end of the inner tube 15 moves to the front end of the outer tube 10, the locking piece can lock and fix the inner tube and the outer tube, and at the moment, the syringe drainage tube 12 is a hose and is matched with the relative motion of the outer tube 10 and the inner tube 15.

For the convenience of access, the housing 2 is provided with a hatch 1 which can be opened and closed, and when the hatch 1 is opened, the syringe 5 can pass through the hatch.

In order to facilitate the opening and closing of the hatch 1, the shell 2 is hinged with the hatch 1 through a pin 4, and a locking clamping groove 20 is arranged on the opposite side of the shell 2 hinged with the hatch 1 and can keep closed stably.

For convenience of fixation, a syringe retainer ring 6 is fixed on the inner wall of the housing 2, and the syringe 5 is fixed in the syringe retainer ring 6.

For convenience, the propelling device 25 is an electric push rod, which is connected with a rechargeable battery 26, the rechargeable battery 26 is electrically connected with the main switch 21, and the housing 2 is provided with a charging socket 27 for charging the rechargeable battery 26.

The LED display 18 can display the advancement of the T-shaped advancement post 24 (i.e., the amount of injection), and the charge level of the rechargeable battery 26.

An injection button 19 is fixed to the outer wall of the housing 2.

In this patent, the handle portion is not sterilized, and the oral cavity portion and the syringe 5 are disposable products in order to accelerate the treatment frequency and reduce the sterilization of the oral cavity portion.

In current clinical work, precise and portable technical equipment is lacked in the medical instruments for vocal cord injection. This has two consequences: 1 due to lack of suitable instruments, clinicians can only use other medical instruments to perform rough clinical operations, such as long-tube injection needle using long forceps, which is not smooth for the clinicians to operate and is not good for precise medical treatment. 2 the length of the instrument required for the vocal cord operation under the self-retaining laryngoscope is about 30 cm, and the instrument is inconvenient to carry, so that the slidable inner tube and outer tube structure is designed, and the inner tube is placed in the lumen of the outer tube when being stored or carried; when an operation is required, the inner tube is pulled to a certain distance and the locking piece can lock and fix the inner tube and the locking piece, so that the flexible and convenient design meets the requirements of portability and intraoperative requirements.

The working principle is as follows:

during assembly, a doctor opens the hatch 1 by locking the clamping groove 20, puts the syringe 5 which sucks the liquid medicine into the shell 2, presses the syringe 5 into the syringe clamping ring 6, and then closes the hatch 1. This completes the combination of the syringe 5 with the housing 2.

The inner tube 15 is pulled out to a predetermined position and rotated to fix the inner tube 15 and the outer tube 10 together.

The outer tube 10 is inserted into the housing 2 from the snap ring 9, the syringe port 8 is butted against the syringe tip port 7, and the elastic circular truncated cone plug 17 is butted against and partially fitted into the snap ring 9.

This completes the assembly.

When injection is needed, a doctor presses the injection button 19, the rechargeable battery 26 releases current, the propulsion device 25 starts to work, the T-shaped propulsion column 24 is pushed to move forwards, and the liquid medicine in the cavity of the syringe 5 is pushed and injected into the vocal cord part through the syringe interface 8, the syringe drainage tube 12 and the syringe needle 13. When the doctor feels that the injection amount is sufficient, the injection button 19 is released, the rechargeable battery 26 stops working, the above steps are stopped in sequence, and finally the injection stops.

Under the condition that vocal cords are difficult to expose or the diseased region of the vocal cords is far away, the straight needle head is difficult to contact the diseased region, so that the needle head 13 of the syringe is small, the needle body can be bent at will, and an operator can conveniently and accurately inject by using the needle head with the bent angle.

Meanwhile, the position sensor 3 is also activated and starts to work, the photosensitive system detects the propelling condition of the T-shaped propelling column 24 through light sensation to analyze and quantify, the amount (injection amount) of the pushed liquid medicine is further calculated, the PLC changes the pushed liquid medicine into a digital signal and transmits the digital signal to the LED display screen 18, the LED display screen 18 displays the injection amount in a digital form, meanwhile, the injection amount can be broadcasted in real time through the voice broadcasting system, and a clinician can clearly know and control the injection dosage through voice broadcasting.

The PLC receives the information of the rechargeable battery 26, analyzes the remaining capacity of the rechargeable battery 26, transmits the information to the LED display 18, and displays the information on the LED display 18, so that the operator can know the battery condition at any time. Of course, during the operation, the ac power can be directly connected to the charging socket 27 to provide the kinetic energy for the operation.

During non-operation, the ultraviolet lamp switch 22 and the ultraviolet lamp 23 are pressed to be energized, and the inside of the housing 2 is sterilized by ultraviolet rays.

During operation, the handle part is sleeved with a surgical sterile transparent covering film, and if the second operation is carried out, the covering film can be replaced, so that the whole system can be in a sterile state in all operation processes.

See the prior art for additional details.

While the preferred embodiments of the present invention have been described, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the general inventive concept, and it is intended to cover all such changes and modifications as fall within the true spirit and scope of the invention.
