Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example.

Referring to Figure 1-2, the throat tumor puncture needle includes a needle body 7 and a first sleeve 1, the first sleeve 1 is made of transparent acrylic material, and one end of the first sleeve 1 is connected with a second sleeve 2; wherein The opposite end of the first sleeve 1 and the second sleeve 2 is provided with an opening, and the outer wall of the opening is provided with an annular arc surface 8, so as to prevent the outer wall of the first sleeve 1 from scratching the patient's throat.

The needle body 7 is located inside the first sleeve 1, and the inner wall of the first sleeve 1 is slidingly connected with the first rubber ring 3. The inner diameter of the first rubber ring 3 is smaller than the outer diameter of the needle body 7, which can play a role in the needle body 7. The role of fixing; and the outer wall of the first rubber ring 3 is provided with tetrafluoromembrane 9, which can reduce the friction force when the first rubber ring 3 slides; the needle body 7 penetrates the first rubber ring 3 and is fixedly connected with it, the first A second sleeve 2 is installed at one end of the sleeve 1 , the second sleeve 2 is a hose, and the diameter of the second sleeve 2 is larger than that of the first sleeve 1 .

A second rubber ring 4 is fixedly connected in the second casing 2, and two V-shaped elastic pieces 5 are fixedly connected between the first rubber ring 3 and the second rubber ring 4. The two V-shaped elastic pieces 5 are arranged oppositely, and the two The V-shaped shrapnel 5 are all offset against the second sleeve 2; the needle body 7 moves through the second rubber ring 4, and the inner wall of the port of the second sleeve 2 away from the first sleeve 1 is fixedly connected with a third rubber ring 6, and the needle body 7 A plastic connector is provided away from the tip of the needle, and the connector of the needle body 7 is movable through the third rubber ring 6, so as to be connected to the external pipeline, thus passing through the first rubber ring 3, the second rubber ring 4 and the third rubber ring 6 can limit the needle body 7.

When the utility model is in use, the medical personnel pinch the second sleeve 2 with the thumb and forefinger, and the thumb and index finger are opposite to the two V-shaped shrapnel 5, and then extend the first sleeve 1 into the patient's throat, which can be viewed through the endoscopic Observe with equipment such as a mirror, so that the first cannula 1 is offset against the tumor, and then the medical staff’s thumb and forefinger squeeze hard. Since the second rubber ring 4 is fixed, the V-shaped shrapnel 5 can be stretched and flattened to drive the needle body 7 to align with the tumor. The first rubber ring 3 moves, so that the needle body 7 protrudes, and the tumor can be punctured, and samples can be taken, or a negative pressure device can be connected to the connector of the needle body 7 for abscess treatment, which is simple and convenient to use and safer.

The above is only a preferred embodiment of the utility model, but the scope of protection of the utility model is not limited thereto. The equivalent replacement or change of the new technical solution and the concept of the utility model shall be covered by the protection scope of the utility model.
