Description

Technical Field

[0001] The utility model relates to a base, in particular to a neuroendoscope base, belonging to the technical field of medical equipment. Background Art

[0002] Neuroendoscopes have been widely used in a variety of neurosurgical diseases such as cerebral hemorrhage and skull base tumors. Neuroendoscopes have the advantages of less trauma, good lighting, magnification, and fewer blind spots.

[0003] The classic surgical method for chronic subdural hematoma (effusion) is burr hole drainage, but because there are often fibrous septa in the hematoma, simple burr hole drainage often has the problem of insufficient drainage and even repeated recurrence of hematoma. In recent years, neuroendoscopy has begun to be used in the removal of chronic subdural hematoma (effusion). Through a small bone window, the hematoma and fibrous septa are removed under neuroendoscopic visualization, which can completely remove the hematoma, shorten the postoperative drainage tube retention and hospitalization time, and reduce the risk of postoperative hematoma recurrence.

[0004] However, when using neuroendoscopy to remove subdural hematoma, the lens needs to be placed into the hematoma cavity through a skin incision, and instruments such as aspirators also need to be placed into the hematoma cavity through a skin incision, and they are often outside the display range of the lens, which poses a risk of damaging brain tissue, especially when changing the direction of the lens and the instrument. As the hematoma is removed, the brain tissue may gradually expand, and the space of the hematoma cavity is further compressed, further increasing the risk of injury. There is an urgent need for a device that can assist neuroendoscopy. Utility Model Content

DETAILED DESCRIPTION

[0017] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0018] Embodiments of the present utility model: Figure 1 and Figure 2 As shown, a neuroendoscope base includes a base body, which is composed of an inner ring body 1, an outer ring body 2 and a roller shaft 3. A plurality of roller shafts 3 are arranged between the inner ring body 1 and the outer ring body 2. A brain pressing assembly is installed on the outer ring body 2. A plurality of fixed seats 4 are arranged on the outer wall of the outer ring body 2. A cross bar 5 is installed on the inner ring body 1. A neuroendoscope socket 6 is opened in the middle position of the cross bar 5.

[0019] It should be noted that the assembly method and working principle of the inner ring body 1, the outer ring body 2 and the roller shaft 3 are the same as those of the needle bearing in the prior art, and the inner ring body 1 can rotate freely in the outer ring body 2. The cross bar 5 is arranged in the inner ring body 1, and the angle of the neuroendoscope can be conveniently adjusted through the rotational cooperation between the inner ring body 1 and the outer ring body 2, and the main function of the cross bar 5 is to support and fix the neuroendoscope.

[0020] In a specific embodiment, four fixing seats 4 are arranged at equal intervals on the outer wall of the outer ring body 2, and the fixing seats 4 are all L-shaped. The vertical part of the fixing seat 4 is fixedly connected to the outer wall of the outer ring body 2, and the bottom surface of the horizontal part of the fixing seat 4 is flush with the bottom surface of the outer ring body 2. A first threaded hole 24 is opened on the horizontal part of the fixing seat 4.

[0021] The main function of the fixing seat 4 is to fix with the human skull, and the fixing seat 4 is fixed on the human skull by screws passing through the first threaded holes 24, so that the outer ring body 2 is fixed on the human skull. The number of fixing seats 4 is at least two, and three or more can be set according to needs.

[0022] Furthermore, the brain pressing assembly includes a mounting plate 23, a connecting rod 7 and a brain pressing plate 8. There are two mounting plates 23. The two mounting plates 23 are fixed on the top surface of the outer ring body 2, and the two mounting plates 23 are symmetrically arranged relative to the axis of the outer ring body 2. The ends of the two mounting plates 23 away from each other extend to the outside of the outer ring body 2, and the ends are formed with long holes 9. Two connecting rods 7 are fixed on the top of the brain pressing plate 8, and the two connecting rods 7 are respectively plugged and connected to the long holes 9 on the two mounting plates 23.

[0023] In this embodiment, the cross-sectional shape of the connecting rod 7 is a rectangle, so a long hole 9 is opened on the mounting plate 23. It should be noted here that the specific shape of the long hole 9 is determined according to the shape of the connecting rod 7. For example, if the cross-sectional shape of the connecting rod 7 is a circle, the long hole 9 should be changed to a round hole. The brain pressing plate 8 is a circular flat plate, and it can also be designed as a circular plate with a slightly upward convex middle portion according to needs. The function of the brain pressing plate 8 is to apply pressure to the brain tissue to prevent the brain tissue from re-expanding after the hematoma is removed, thereby effectively preventing the neuroendoscope from touching the brain tissue and achieving effective protection of the brain tissue.

[0024] Furthermore, a plurality of limiting grooves 10 are formed on opposite surfaces of the two connecting rods 7, and the limiting grooves 10 are arranged at equal intervals along the length direction of the connecting rod 7. A mounting hole 11 is opened in the mounting plate 23, and a ball 12, a spring 13 and a plug 14 are arranged in the mounting hole 11, and the plug 14 is threadedly connected to the mounting hole 11.

[0025] The function of this structure is to limit the position of the connecting rod 7, so that after the connecting rod 7 is adjusted, the ball 12 cooperates with the limiting groove 10 to limit the position of the connecting rod 7, so that the brain pressing plate 8 can press the brain tissue. This structure is only a preferred solution, and other structures that can limit the position of the connecting rod 7 can also be applied to the present invention, such as using a positioning rod structure, a claw structure, etc.

[0026] Furthermore, two mounting seats are fixedly provided on the inner wall of the inner ring body 1, and the two mounting seats are symmetrically arranged relative to the axis of the inner ring body 1, and the two ends of the cross bar 5 are installed in the two mounting seats. The mounting seat includes a support block 15 and a pressure block 16, one end of which is fixedly connected to the inner wall surface of the inner ring body 1, a stud 17 is fixedly provided on the top of the support block 15, and a through hole 18 is opened on the pressure block 16. The pressure block 16 is installed on the top of the support block 15, and the stud 17 passes through the through hole 18 and is threadedly connected with a hand nut 19, and an arc groove 20 is formed on the top surface of the support block 15 and the bottom surface of the pressure block 16.

[0027] The installation seat is used to control the crossbar 5, so that the crossbar 5 can rotate freely on the installation seat or be fixed on the installation seat. When the hand nut 19 is tightened, the support block 15 and the pressure block 16 clamp the end of the crossbar 5, and the crossbar 5 is fixed. When the hand nut 19 is loosened, the crossbar 5 can rotate. Similarly, other structures can be used instead of the installation seat. All structures that can meet the requirements of installing the crossbar 5 and realizing the locking and rotation of the crossbar 5 can be applied to the utility model.

[0028] Furthermore, a connecting plate 21 is fixedly provided in the middle of the crossbar 5, and a clamp 22 is fixedly provided on the connecting plate 21, and the clamp 22 is coaxial with the neuroendoscope jack 6. The function of the clamp 22 is to clamp the neuroendoscope tightly so that the neuroendoscope is fixed on the crossbar 5. The clamp 22 is a preferred solution, and the clamp 22 can also be replaced by a cable tie or other structures.

[0029] The working principle of the utility model is as follows: during the operation, after opening the skull through a small bone window, the hematoma under the bone window is first removed by using a neuroendoscope under direct vision, and a brain cotton sheet is laid on the surface of the cerebral cortex under the bone window to protect the brain tissue. After the connecting rod 7 of the brain pressing plate 8 passes through the long hole 9 on the mounting plate 23, the fixing seat 4 is placed on the skull, and four fixing seats 4 are fixed on the skull using screws, and then the position of the connecting rod 7 is adjusted, and the brain pressing plate 8 is gently placed on the cotton sheet on the brain surface, and the brain tissue is gently stretched open, and the connecting rod 7 is positioned under the action of the spring 13 and the ball 12. Then the working channel is passed through the hoop 22 on the crossbar 5 and the neuroendoscope jack 6, and the hoop 22 is used to fix it after adjusting the length. After adjusting the angle, the hand-tightened nut 19 is tightened, and the hematoma outside the bone window can be removed through the working channel. At this time, the channel can be rotated in a plane parallel to the base, and can also be pitched in a plane perpendicular to the base, so as to meet the needs of removing hematomas in different parts. Due to the limitation of the two connecting rods 7, it is not possible to directly remove the hematoma 360°. After one side is removed, the working channel is taken out, the hand nut 19 is loosened, the cross bar 5 is rotated so that the neuroendoscopic socket 6 faces the other side, the hand nut 19 is tightened, and the working channel is installed in the same way as before to complete the hematoma removal on the other side. In this way, the hematoma removal at 360° can be completed.

[0030] The above describes in detail the structure, features and effects of the utility model based on the embodiments shown in the drawings. The above is only a preferred embodiment of the utility model, but the utility model is not limited to the scope of implementation shown in the drawings. Any changes made in accordance with the concept of the utility model, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and the drawings, should be within the protection scope of the utility model.
