Single-tube surgical catheter

Abstract

This invention is a single-tube surgical catheter, comprising a base, an assembly section, a locking section, and a guide section. The assembly section is located on the outer peripheral wall of the base and protrudes outward from opposite sides of the base. The locking section is circumferentially located on the outer peripheral wall of the base. The guide section is located at one end of the base and extends away from the base, with its inner hole communicating with the inner hole of the base. This single-tube surgical catheter can be connected and fixed to a handle through the assembly section for resection operations, and can be connected and fixed to a suction tube of a negative pressure device through the locking section for aspiration operations, thus possessing versatility. Furthermore, during resection operations, the single-tube surgical catheter allows laser fiber to be inserted, and under the guidance of the guide section, the shape of the laser fiber can be controlled and aligned with the affected area, thereby effectively utilizing fiber optic laser technology for surgery.

Claims

1. A single-tube surgical catheter, comprising: a base; a set of portions disposed on the outer peripheral wall of the base and protruding outward from opposite sides of the base; an engaging portion circumferentially disposed on the outer peripheral wall of the base; and a guiding portion disposed at one end of the base and extending in a direction away from the base, wherein an inner hole of the guiding portion communicates with an inner hole of the base.

2. The single-tube surgical catheter as described in claim 1, wherein, The engaging part includes two engaging structures that are arranged adjacently and in an arc shape.

3. The single-tube surgical catheter as described in claim 1, wherein, A guide structure is formed at the connection between the inner hole of the base and the inner hole of the guide portion, and the diameter of the guide structure gradually decreases from the base toward the guide portion.

4. The single-tube surgical catheter as described in claim 2, wherein, A guide structure is formed at the connection between the inner hole of the base and the inner hole of the guide portion, and the diameter of the guide structure gradually decreases from the base toward the guide portion.

5. A single-tube surgical catheter as described in any one of claims 1 to 4, wherein, The guide section extends along the length of the base.

6. A single-tube surgical catheter as described in any one of claims 1 to 4, wherein, The guide section includes a connecting section and a turning section. The connecting section is connected to the base and extends along the length direction of the base. The turning section is connected to the connecting section and extends upward along the length direction of the connecting section.

7. The single-tube surgical catheter as described in claim 6, wherein, The end of the turning section of the guide can extend downward along the length of the turning section.

8. The single-tube surgical catheter as described in claim 6, wherein, The end of the turning section of the guide can extend upward along the length of the turning section.

9. A single-tube surgical catheter as described in any one of claims 1 to 4, wherein, The guide section includes a connecting section and a turning section. The connecting section is connected to the base and extends along the length direction of the base. The turning section is connected to the connecting section and extends downward along the length direction of the connecting section.

10. The single-tube surgical catheter as described in claim 9, wherein, The end of the turning section of the guide can extend downward along the length of the turning section.

11. The single-tube surgical catheter as described in claim 9, wherein, The end of the turning section of the guide can extend upward along the length of the turning section.
