The brain tumor interstitial cavity fluid circulation intervention device has the functions of accurately monitoring brain tumor evolution in real time, accurately diagnosing tumor recurrence in an early stage and directly and locally treating recurrent tumors, and is used for solving the technical problems of whole-course sampling monitoring and accurate diagnosis and treatment after brain malignant tumor operation; particularly, an interventional tool is provided for solving the technical problems of sampling monitoring, early precise diagnosis and direct local treatment in the recurrence and progression stage after brain malignant tumor treatment.

An implant for fixing a cranial bone flap in a cranial opening of an osseous skull includes a flexible mesh structure having webs and openings formed between the webs. The flexible mesh structure is made of a plastic material and is designed to be fastened to the bone flap and to the osseous skull.

The utility model discloses a brain drainage pipeline fixing hood which effectively achieves the purpose of fixing different drainage positions of a ventricle and comprises a hood body, a fixing belt and a binding belt. The lower side of the cover body is fixedly connected with a first covered edge in a front-back symmetry mode, and the lower side of the cover body is fixedly connected with a second covered edge in a left-right symmetry mode. The mask body comprises a plurality of annular belts and a plurality of semi-annular belts, each annular belt is horizontally arranged, each semi-annular belt and the annular belts are arranged in a crossed mode to form a net-shaped structure, and each semi-annular belt is fixedly connected with the corresponding annular belt; the drainage tube fixing device is novel in structure, ingenious in conception and easy and convenient to operate, a drainage tube can be effectively clamped and fixed, the function of secondary fixing of the drainage tube is added, the drainage tube fixing device can be stably fixed to the head of a patient, and the situation that the drainage tube is bent is reduced.

A nerve ablation apparatus is provided, including supporting bodies (110, 210, 310, 410) and mounting members (120, 220, 420); the mounting members (120, 220, 420) are provided along the circumferences of the supporting bodies (110, 210, 310, 410) and of mesh structures; the mounting members (120, 220, 420) include first regions (121, 222) and second regions (122, 223) provided along the circumferences of the supporting bodies (110, 210, 310, 410) and include the mesh structures formed by a plurality of mesh wires; in the first regions (121, 222), the plurality of mesh wires intersect and at least a portion of the mesh wires are fixedly connected at intersections. Thus, when the supporting bodies (110, 210, 310, 410) are released in an airway (810), the supporting bodies (110, 210, 310, 410) push the mounting members (120, 220, 420) to attach to an inner wall of the airway (810); when the first regions (121, 222) and the second regions (122, 223) are compressed by the airway (810), reduction amounts of areas of meshes on the first regions (121, 222) are small, and when the first regions (121, 222) and the second regions (122, 223) are energized, ablation energy emitted by the first regions (121, 222) is less than ablation energy emitted by the second regions (122, 223), thereby reducing the burn of an esophagus (820) by the mounting members (120, 220, 420).

The present invention discloses a left atrial appendage occluder with an interleaved connection and an assembly method thereof. The left atrial appendage occluder includes a sealing part and an anchoring part which are connected to each other. The anchoring part has a reticular structure formed by cutting. The sealing part and the anchoring part respectively have connection parts formed by shape convergence. The connection parts of the sealing part and the anchoring part extend towards each other and are fixed in a staggered manner. By improving the connection method, the present invention realizes the interleaved connection between the sealing part and the anchoring part, which can make the sealing part adhere more closely to the left atrial appendage and block the opening of the left atrial appendage, so as to reduce the incidence of internal leakage and residual shunt.
