Detailed Description

The following will explain in detail the specific embodiment of the injector in the inferior cavity of the cystoscope provided by the present invention with reference to the attached drawings. It should be noted that the drawings are only for showing the relative positional relationship of the respective components, and do not limit the specific dimensions thereof.

Fig. 1 is a schematic structural view of the injector in the lower cavity of the cystoscope of the present invention. The utility model discloses the syringe can insert in the operation pore of cystoscope to reach the pathological change position through the operation pore, thereby carry out local medicine injection.

Referring to fig. 1, the intravesical syringe of the present invention includes a needle 1. The needle 1 is hollow inside, i.e. it allows the passage of liquids. The needle head 1 is made of metal materials, so that the needle head can be naturally deformed and is not easy to bend, the needle head can smoothly enter and exit an operation pore canal of the cystoscope, and the needle head 1 can be ensured to have certain hardness and can be smoothly inserted into a diseased part.

The needle 1 has a first end 10 and a second end 11 arranged opposite to each other. Wherein the first end 10 is a connecting end, which can be connected with other structures for fixing the needle 1. The second end 11 is a pointed end which can be inserted into a site where a liquid injection is required, and in particular, the second end 11 can penetrate into a lesion site by an external force.

The needle 1 is insertable into an operating channel (not shown in the drawings) of a cystoscope. Wherein, the length of the needle 1 is longer than the length of the operating hole of the cystoscope, so that the first end and the second end of the needle 1 protrude out of the operating hole of the cystoscope, thereby facilitating the operation.

The length of the needle 1 ranges from 30 cm to 60 cm, and specifically, in this embodiment, the length of the needle 1 may be designed to be 30 cm according to the average length of the male urethra of about 15 cm to 20 cm and the length of the operating channel of the cystoscope of about 25 cm. In other embodiments of the present invention, the corresponding length of the needle 1 may be selected according to the length of the operation channel of the cystoscope into which the needle 1 is inserted.

Since the needle 1 needs to be inserted into the operation hole of the cystoscope, the circumferential size of the needle 1 is smaller than the inner circumferential perimeter of the operation hole of the cystoscope. Specifically, in this embodiment, the needle 1 is an F6 needle for the operating channel of the F-18 cystoscope, wherein F refers to the inside circumference of the needle, that is, the inside circumference of the needle 1 is less than or equal to 6 cm for the operating channel of the F-18 cystoscope. In other embodiments of the present invention, the model of the needle 1 can be selected according to the inner perimeter of the operation channel of the cystoscope.

Fig. 2 is an enlarged view of the second end. Referring to fig. 1 and 2, at the second end 11, the outer side wall of the needle has scale marks 12. The graduated markings may be used to indicate the depth of insertion of the needle 1 into the lesion to provide a reference for the user. In this embodiment, the scale mark 12 is a millimeter scale mark, and the total length of the scale mark 12 is 1 centimeter, in other embodiments, the scale mark 12 may also adopt other units, and the length of the scale mark 12 may also be changed according to the user's needs.

Further, with continued reference to fig. 1, the injector of the present invention includes a propelling part 2. One end of the propelling part 2 is provided with a needle seat 21, and the first end 10 of the needle 1 is connected with the needle seat 21. Wherein the propelling part 2 is a conventional common syringe, and the structure of the propelling part can be obtained from the prior art by a person skilled in the art.

The utility model discloses refractor can operate in cystoscope operation pore, can carry out local intravenous injection, improves clinical curative effect, and is with low costs, and the preparation degree of difficulty is not big, has further saved medical resource, alleviates patient's economic burden, can popularize and apply by a large scale.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
