Preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings, but the well-known technical parts will be omitted or compressed for brevity of description.

As shown in Figures 1 to 4, the tool 100 for access to the body of the present invention comprises a first tool 120 and a second tool 140.

The tool 100 for access to the body includes a first tool 120 and a second tool 140, which are used in a combined or separated state. The internal body access tool 100 is used as a tool for accessing the affected part through the tissue into the body of the human body that requires the procedure of surgery or surgery.

The tool 100 for access to the body approaching the target body in this way separates the second tool 140 leaving only the first tool 120 on the human body in the combined first tool 120 and second tool 140. By using the tube of the first tool 120 by connecting to other surgical instruments such as nozzles, funnels and syringes to allow the procedure or surgery, or to insert the necessary medicine into the body in the affected area.

Here, the tool for accessing the body to penetrate the tissue to prevent rotation between the first tool 120 and the second tool 140 in a state where the first tool 120 and the second tool 140 are coupled It is to be transmitted to increase the strength without damage to the various aspects of the force over the (100).
