[0027] The present invention is further described below with reference to specific embodiments. Figure 1 —2:

[0028] A medical needle for treating tumors, comprising a metal needle tube 1 and a three-way connector 2 arranged at the tail end of the metal needle tube 1, wherein the tail end of the metal needle tube 1 is provided with a central hole 3 connected to the injection and suction port 5 of the three-way connector 2, the central hole 3 is opened along the axis of the metal needle tube 1 to the rear side of the needle tip of the metal needle tube 1, and the bottom of the central hole 3 is provided with a flow hole 4 along the radial direction of the metal needle tube 1, and the other two ends of the three-way connector 2 are respectively a positive and negative pressure port 6 and a cleaning and waste discharge port 7, the positive and negative pressure port 6 is used to communicate with medical liquid, and the medical liquid is pushed into the positive and negative pressure port 6 by the positive pressure of an external positive and negative pressure power source; or the mixed liquid is sucked out of the positive and negative pressure port 6 to the outside by the negative pressure of the external positive and negative pressure power source, and the three ports of the three-way connector 2 are all provided with a valve assembly 8 that can block or conduct the corresponding port. Among them, the external positive and negative pressure power source can be a common pump body or a syringe.

[0029] The present invention rationally designs a medical needle, which uses a metal needle tube 1 to pierce a human tumor, injects a medical liquid to mix with the secretions and water in the tumor to form a mixed liquid, and finally sucks out the mixed liquid, thereby reducing the size of the tumor, accelerating the filling of normal human tissues, reducing the living space of the tumor, and reducing the harm of the tumor to the human body caused by recurrence and growth.

[0030] At the same time, compared with the existing medical needles, the medical needle of the present invention can effectively reduce the damage to human soft tissue during the insertion process by arranging the flow holes 4 on both sides of the needle tip of the metal needle tube 1.

[0031] Furthermore, in order to facilitate the insertion of the metal needle tube 1 into or withdrawal from the human soft tissue, a needle handle 9 for the operator to hold is provided at the tail end of the metal needle tube 1 .

[0032] Furthermore, the valve assembly 8 is a ball valve or a butterfly valve, that is, the opening and closing of the three valve assemblies 8 are manually controlled by humans, which is low in cost.

[0033] Furthermore, in order to facilitate the puncture of the metal needle tube 1, the needle tip of the metal needle tube 1 is a conical or multi-faceted structure.

[0034] In addition, in order to facilitate the flow of medical liquid between the injection and aspiration port 5 and the positive and negative pressure port 6, the injection and aspiration port 5 and the positive and negative pressure port 6 of the three-way connector 2 are located on the same axis, and the cleaning and waste discharge port 7 is inclined away from the metal needle tube 1. The medical liquid can be a specially formulated liquid medicine, and in this embodiment, the medical liquid is physiological saline or ice water.

[0035] A method for using a medical needle for treating a tumor, wherein the medical needle is the above-mentioned medical needle for treating a tumor, and the method for using the medical needle comprises the following steps in sequence:

[0036] Step 1: inserting the needle tip of the metal needle tube 1 from the human soft tissue into the tumor;

[0037] Step 2: Close the corresponding valve assembly 8 at the cleaning and waste discharge port 7, and open the corresponding valve assembly 8 of the injection and suction port 5 and the positive and negative pressure port 6;

[0038] Step 3: Use the external positive and negative pressure power source to slowly push the saline or cold water with positive pressure, so that the saline or cold water enters the tumor through the positive and negative pressure port 6, the injection and suction port 5 and the metal needle tube 1, and wait for the saline or cold water to mix and dilute with the secretions in the tumor to form a mixed liquid;

[0039] Step 4: Use the negative pressure of an external positive and negative pressure power source to slowly absorb the mixed liquid in the tumor, so that the mixed liquid in the tumor is sucked out through the metal needle tube 1, the injection and suction port 5, and the positive and negative pressure port 6; wherein, the suction is slow, a small amount of the mixed liquid is sucked out each time, and wait for the mixed liquid to gather before sucking again, until it is impossible to continue to draw.

[0040] Step 5: Close the corresponding valve components 8 at the injection and suction ports 5, and open the corresponding valve components 8 at the cleaning and waste discharge port 7 and the positive and negative pressure ports 6;

[0041] Step 6: Push the physiological saline or cold water with positive pressure through the external positive and negative pressure power source, so that the physiological saline or cold water enters the three-way channel through the positive and negative pressure ports 6 and is discharged outward from the cleaning and waste discharge port 7; so as to achieve the purpose of cleaning the three-way connector 2.

[0042] Step 7: Execute steps 2 to 6 in a loop, and execute the loop more than twice, and finally proceed to step 8; that is, the number of loops should be determined according to the actual tumor size and the viscosity of the tumor endocrine.

[0043] Step 8: Pull out the metal needle tube 1.

[0044] In addition, a preparatory step is included before step one: closing the corresponding valve assembly 8 at the cleaning and waste discharge port 7, and opening the corresponding valve assembly 8 of the injection and aspiration port 5 and the positive and negative pressure port 6, and slowly pushing physiological saline or cold water through the positive pressure of an external positive and negative pressure power source to squeeze out the air and medical cleaning fluid in the three-way connector 2 and the metal needle tube 1.

[0045] Of course, before the actual medical operation, a professional surgeon needs to use imaging technology to determine the location of the tumor and select a suitable insertion position for the metal needle tube 1 so as to be close to the tumor and avoid human organs, blood vessels, and organs.

[0046] Among them, it should be noted that: the present invention can reduce the tumor to a range that does not affect the health of the human body, and the components of the tumor include secretions and water, the components of the secretions are about 25%, and the water content is about 75%. The method of extracting the secretions and water in the tumor out of the body can make the tumor shrink naturally, and by injecting ice water or saline, the tumor growth can be prevented, the concentration of secretions in the tumor can be reduced, and the tumor can be gradually removed from the body. At the same time, injecting ice water or saline can reduce the temperature in the tumor to change the living environment of tumor cells, and the tumor cells will stop growing or die, thereby preventing the tumor from growing. In addition, the volume of liquid extracted each time for treatment is greater than the volume of liquid injected. In the process of gradual shrinkage of the tumor, the vacated space is gradually filled by the normal tissue produced by the human body, thereby reducing the harm of the tumor to the human body and allowing the human body to gradually return to a normal healthy state. In addition, when the tumor volume is significantly reduced, the secretions and water outside the tumor are also extracted and extracted out of the body to accelerate the filling of normal tissues of the human body.

[0047] This method directly draws the secretions and water in the tumor out of the body. The treatment process is similar to that of a blood draw. After the treatment, it will not cause pain to the patient and will not cause sequelae or side effects.

[0048] The above embodiment is only one of the preferred embodiments of the present invention, and is not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes made based on the shape, structure, and principle of the present invention should be included in the protection scope of the present invention.
