[0032] Reference Figures 1 to 5 The utility model provides a novel Ommaya capsule 1.

[0033] In an embodiment of the utility model, the new Ommaya capsule 1 includes: a capsule body 10, the capsule body 10 is provided with a liquid storage chamber 10a and a liquid outlet 10b connected to the liquid storage chamber 10a; a liquid supply conduit 20, the liquid supply conduit 20 is connected to the capsule body 10 and is connected to the liquid outlet 10b; a bone hole fixing member 30, the bone hole fixing member 30 is detachably connected to the capsule body 10 and can be embedded in the skull hole, and the liquid supply conduit 20 is detachably connected to the bone hole fixing member 30.

[0034] Specifically, in this embodiment, the capsule 10, the liquid supply catheter 20 and the bone hole fixing piece 30 are all made of medical-grade plastic materials. The capsule 10 is a cylindrical shell-shaped cavity structure, forming a liquid storage cavity 10a and a liquid outlet 10b of the liquid storage cavity 10a. One end of the liquid supply catheter 20 is sleeved on the liquid outlet 10b, and the other end extends toward the lesion, and the middle part is detachably connected to the bone hole fixing piece 30.

[0035] The novel Ommaya capsule 1 of the present application makes full use of the position of the skull hole and provides a bone hole fixing part 30 that can be embedded therein, thereby fully fixing the capsule body 10. This can largely avoid displacement of the capsule body 10 during the treatment process. The capsule body 10 can be fixed more firmly to the human head, thus achieving a better treatment effect.

[0036] Please see again Figure 2In this embodiment, the bone hole fixing member 30 includes an elastic fixing buckle 31 and a connecting rod 32 made of elastic medical grade plastic material. The connecting rod 32 is integrally formed at the end of the elastic fixing buckle 31. The shape of the elastic fixing buckle 31 is circular to adapt to the shape of the skull hole. The end of the connecting rod 32 away from the elastic fixing buckle 31 is detachably connected to the capsule 10, wherein the capsule 10 is provided with a plurality of connecting positions 121, and the plurality of connecting positions 121 are arranged at intervals along the circumference of the capsule 10. The end of the connecting rod 32 is detachably connected to any connecting position 121. By setting a plurality of connecting positions 121, it is convenient for medical staff to adjust the connection position 121 between the capsule 10 and the elastic fixing buckle 31 in actual operation, thereby facilitating surgical operation.

[0037] Please see again Figure 2 and Figure 4 Further, the capsule 10 includes a body 11 and a connecting substrate 12. The connecting substrate 12 is recessed on one side facing the body 11 to form a connecting groove 12a. The shape of the connecting groove 12a is adapted to the shape of the body 11. The lower half of the body 11 is snapped into the connecting groove 12a. The connecting substrate 12 is provided with a plurality of connecting holes 121a in the circumferential direction. The aperture of the connecting hole 121a is smaller than the diameter of the connecting rod 32, so that the end of the connecting rod 32 can be elastically embedded in the connecting hole 121a to connect the body 11 and the connecting rod 32. In the present application, the connection operation of the connecting rod 32 and the connecting substrate 12 can be facilitated by providing a plurality of connecting holes 121a. In actual use, the connecting position 121 of the connecting rod 32 or the direction of the liquid supply conduit 20 can be adjusted by plugging it into any connecting hole 121a or rotating the body 11, so that it can better adapt to the needs of different diseases and people, thereby improving the treatment effect.

[0038] Furthermore, the connection position 121 is provided with a mounting notch 121b connected to the connection card hole 121a, and the mounting notch 121b penetrates the upper plate surface of the connection base plate 12. In the present application, since the diameter of the connection rod 32 is larger than the aperture of the connection card hole 121a, by providing the mounting notch 121b, the medical staff can clamp the end of the connection rod 32 into the connection card hole 121a at the side or top of the connection base plate 12, so that the connection between the connection rod 32 and the capsule 10 is more convenient.

[0039] Please see again Figure 4In this figure, the dotted line portion is a fixed connection line, wherein the fixed connection line is generally a surgical line used in surgery, and the connection position 121 is also provided with a fixed line hole 121c that passes through the upper and lower surfaces of the connection substrate 12, and the fixed line hole 121c is located on opposite sides of the connection card hole 121a. By providing two fixed line holes 121c, the fixed connection line can be passed through the two fixed line holes 121c and finally wrapped around the upper part of the capsule 10, so that the connection between the connection substrate 12 and the body 11 is more stable.

[0040] In this embodiment, the elastic fixing buckle 31 is provided with a catheter fixing hole 31a and a drainage tube fixing hole 31b which pass through its upper and lower surfaces, wherein the aperture of the catheter fixing hole 31a is 3 mm, and the aperture of the drainage tube fixing hole 31b is 6 mm, which are respectively compatible with the diameters of the currently commonly used liquid supply catheter 20 and the external ventricular drainage tube. The elastic fixing buckle 31 is snapped into the skull hole, and the liquid supply catheter 20 and the external ventricular drainage tube are respectively penetrated through the catheter fixing hole 31a and the drainage tube fixing hole 31b, and the two extend into the cranial cavity and directly reach the lesion. In this way, the connection between the liquid supply catheter 20 and the external ventricular drainage tube is more stable, the effect of delivering the drug solution is more stable, and the therapeutic effect of the new Ommaya capsule 1 is better.

[0041] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
