Technical Field

The present invention belongs to the technical field of tumor interventional medical instruments, and in particular relates to a tumor interventional treatment device.

Background technique

Tumor refers to a new growth formed by the proliferation of local tissue cells under the action of various tumorigenic factors. Because this new growth is mostly a space-occupying block-like protrusion, it is also called a growth. According to the cell characteristics of the new growth and the degree of harm to the body, tumors are divided into two categories: benign tumors and malignant tumors. Interventional radiology, also known as interventional therapy, is an emerging discipline that has developed rapidly in recent years and integrates imaging diagnosis and clinical treatment. It is a general term for a series of technologies that use puncture needles, catheters and other interventional equipment to introduce specific instruments into the lesion site of the human body through natural channels or tiny incisions under the guidance and monitoring of imaging equipment such as digital subtraction angiography, CT, ultrasound and magnetic resonance imaging.

Working principle: A person skilled in the art turns the turning handle 111 to drive the connecting rod 109 to rotate. Under the action of the No. 1 support rod 203, the connecting rod 109 rotates to drive the No. 1 bevel gear 201 to rotate. The No. 1 bevel gear 201 rotates to drive the No. 2 bevel gear 205 to rotate. The No. 2 bevel gear 205 rotates to drive the connecting block 206 connected to the No. 2 support rod 204 to rotate. When the square groove 207 is connected to the square block 104 on the top of the No. 2 gear 105, the No. 2 gear 105 drives the connecting block 206 connected to the No. 1 gear 102 to rotate. The threaded rod 101 connected to the stopper 302 rotates in the stopper frame 302. Since the radius of the second gear 105 is large, the stopper frame 302 drives the needle to move faster, which is convenient for piercing the human body. After the needle is inserted into the human body, the flap 107 is rotated to adjust the position of the stopper block 2 so that the square groove 207 is connected to the square block 104 at the top of the third gear 106. The third gear 106 drives the second gear 105 to rotate. Since its radius is small, the speed of insertion into the human body will also be slowed down. After the needle enters the human body, the speed is too fast, causing other organs of the human body to be damaged. In case of damage to the organ, the slot 503 is aligned with the leaked part of the second T-block 404 and inserted. The bottom of the slot 503 pushes the second T-block 404 to move in the second sliding groove 401. The movement of the second T-block 404 drives the second gear plate 405 to move. The second gear plate 405 drives the fourth gear 4 to rotate. The rotation of the fourth gear 4 drives the first T-block 306 connected to the first gear plate 307 to move, so that a part of the first T-block 306 is moved out of the groove 301, and the limit frame 302 can be moved. When not in use When the needle is inserted into the syringe 6, the limit frame 302 is moved to the top of the limit groove 308. Under the action of the spring 403, the syringe 6 is taken out so that the No. 2 T-block 404 drives the No. 1 T-block 306 to return to the groove 301. The limit frame 302 cannot move, thereby ensuring the safe use of the equipment. The two No. 2 annular blocks 602 are rotated to adjust the position of the No. 1 annular block 502. The two No. 2 annular blocks 602 can fix the position of the No. 1 annular block 502, thereby adjusting the position of the connected syringe 6, which is convenient for adjusting the insertion depth of the needle.

The above embodiments are only used to illustrate the technical solutions of the present invention, but not to limit them.
