Description

Dermatological puncture and drainage needle

technical field

The utility model belongs to the field of medical equipment, in particular to a puncture and drainage needle for dermatology.

Background technique

The needle of the puncture and drainage needle for dermatology in the prior art is pointed and inclined. During the puncture process, the puncture needle may cause damage to the deep normal subcutaneous tissue of the patient due to the needle being inserted too deep. In addition, medical personnel need to use a syringe when draining the patient, but the capacity of the syringe is limited, so the syringe should be pulled out after the drainage tube is clamped when it is full, and the hydrops in the syringe will be discharged. This operation not only needs to be repeated, but also clamping the drainage tube can easily lead to damage of the drainage tube.

Utility model content

The purpose of this utility model is to provide an improved puncture and drainage needle for dermatology to effectively solve the above-mentioned technical problems and overcome the defects in the above-mentioned prior art.

In order to achieve the above object, the utility model adopts the following technical solutions.

A puncture and drainage needle for dermatology, comprising a skin-breaking needle, a needle core and a drainage device, wherein the needle of the skin-breaking needle is an inclined-plane opening; the needle core is hollow tubular, and its head end is a tapered blunt head, The needle core is inserted into the skin breaking needle; the drainage device is connected with the tail end of the needle core.

Further, the drainage device includes a sleeve and a suction tube, the tail end of the needle core is inserted into the sleeve, the suction tube is sleeved on the sleeve, and the upper end of the suction tube is set There is a handle, and the lower end of the suction pipe is provided with a discharge pipe.

Further, several side holes are provided on the needle core.

The beneficial effects of the utility model are as follows: first, the needle core of the puncture and drainage needle for dermatology of the utility model is blunt, which avoids the risk of damaging normal subcutaneous tissue during the puncture process, and reduces the operating pressure of medical staff. Second, the puncture and drainage needle for dermatology of the present utility model does not need to pull out the needle barrel again and again, and does not need to clamp the drainage tube, thereby improving the efficiency of drainage and avoiding the damage caused by clamping the drainage tube. The drain tube is broken.

Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

The puncture and drainage needle for dermatology of the present utility model, as shown in Figure 1, comprises a skin breaking needle 4, a needle core 5 and a drainage device, the needle head 3 of the skin breaking needle 4 is an inclined plane opening; 1 is a conical blunt head, and the needle core 5 is inserted into the skin breaking needle 4; the drainage device is connected with the tail end of the needle core 5. The drainage device includes a sleeve 6 and a suction tube 7, the tail end of the needle core 5 is inserted into the sleeve 6, the suction tube 7 is sleeved on the sleeve 6, the upper end of the suction tube 7 is provided with a handle 8, the suction tube The lower end of 7 is provided with discharge pipe 9.

Preferably, several side holes 2 are provided on the side near the head end of the needle core 5 .

When using the puncture and drainage needle for dermatology of the present utility model to perform surgery, the needle head 3 of the skin-breaking needle 4 is moved forward to the head end of the needle core 5, so that the head end 5 is placed behind the needle head, and the skin-breaking needle is moved forward after the skin is broken. Withdraw so that the stylet remains under the skin. Fix the needle core, pull the handle 8 to drain the liquid into the suction tube and discharge it through the discharge tube. Push the handle 8 toward the head end side of the needle core 5, and then pull the handle 8 outward to continue drainage.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the implementation scope of the present invention; if it does not depart from the spirit and scope of the present invention, any modification or equivalent replacement of the present invention shall be covered by the claims of the present invention. within the scope of protection.
