Description

Technical Field

[0001] The present application belongs to the technical field of medical devices, and in particular, relates to a skull decompression connector. Background Art

[0002] Cranioplasty is a mature technology in medicine, but severe complications such as intracranial hypertension may occur after surgery and need to be treated in a timely manner. Intracranial hypertension refers to increased intracranial pressure, which may cause compression and dysfunction of brain tissue. Intracranial hypertension may be caused by a variety of reasons, including cerebral edema, hemorrhage, infection, etc. Swelling and inflammation in the surgical area may occur after surgery, leading to increased intracranial pressure. In addition, brain tissue damage and inflammatory reactions may be caused during surgery, further increasing intracranial pressure. If symptoms of high intracranial pressure occur, such as severe headache, nausea, vomiting, impaired consciousness, etc.

[0003] Treatments for high intracranial pressure include medication and surgery. Medication may include the use of diuretics, drugs that reduce intracranial pressure, etc. Surgical treatment may include ventricular puncture and drainage, intracranial pressure monitoring and control, etc. The above surgical treatments are relatively risky and complicated.

[0006] The locking cover and the bottom cover are detachably connected as one body through the connecting piece I to form a clamp I of the connector, and the clamp I is used to clamp the skull to be repaired;

[0007] The movable cover and the bottom cover are detachably connected as one body through the connecting piece II to form a clamp II of the connector, and the clamp II is used to clamp the skull repair piece;

[0008] Wherein, the connecting member II is selected from a tension spring.

[0009] The method for using the skull decompression connector of the present application includes: pre-assembling the locking cover and the bottom cover, installing them into the edge of the skull to be repaired, pressing the locking cover, and fixing the locking cover and the bottom cover to the skull to be repaired by snapping; using a tool to fix one end of the tension spring on the bottom cover, and fixing the other end of the tension spring on the movable cover, and the movable cover is tightly pressed on the skull repair part by the tension of the tension spring, thereby realizing a fixed connection between the skull and the repair part; when the pressure on the patient's brain tissue increases, the skull repair part can be moved up and down within a smaller range by compression and tension of the tension spring, thereby relieving the pressure on the patient's brain tissue.

[0010] Optionally, the tension spring is made of metal.

The repair part can be clamped in conjunction with the movable cover and the bottom cover. The model and material of the tension spring can be determined according to the actual use conditions.

[0014] Optionally, one end of the tension spring is detachably connected to the bottom cover, and the other end of the tension spring is detachably connected to the movable cover.

[0015] Optionally, the connecting member I is selected from a buckle.

[0016] Optionally, the protruding portion of the buckle is arranged on the locking cover, and the groove portion of the buckle is arranged on the bottom cover.

[0019] Optionally, the movable cover, the locking cover and the bottom cover all have a thickness of 0.5 to 1.2 mm.

[0020] The thickness of the movable cover, foldable cover and bottom cover of the present application can be adaptively designed according to actual use conditions.

[0021] Optionally, the movable cover and the locking cover are tightly spliced ​​on the same horizontal plane.

[0022] After the connector of the present application is assembled, chuck I clamps the edge of the skull to be repaired, and chuck II clamps the skull repair piece, thereby achieving the effect of fixedly connecting the skull and the repair piece. A better effect is that when the connector is in use, the movable cover and the locking cover are tightly spliced ​​on the same horizontal plane, thereby achieving the effect of smoothing the surface of the skull repair.

[0023] Optionally, the clamping distance of the chuck 1 is less than or equal to the thickness of the skull to be repaired.

[0024] In the present application, the clamp I is formed by the locking cover and the bottom cover being connected by snapping. The clamping distance is the vertical distance between the locking cover and the bottom cover when the connector is in use. The size of the clamping distance should be sufficient to clamp and fix the skull to be repaired without loosening or sliding. The size of the clamping distance can be designed according to the thickness of the skull.

[0025] Optionally, the clamping distance of the clamp II is less than or equal to the thickness of the skull repair component.

[0026] The clamp II of the present application is formed by the movable cover and the bottom cover being tightened and connected by a tension spring. The clamping distance is the vertical distance between the movable cover and the bottom cover when the connector is in use. The size of the clamping distance should be suitable for clamping and fixing the skull repair part to prevent it from loosening or sliding. The size of the clamping distance can be designed according to the thickness of the skull repair part.

[0027] Compared with the prior art, this application has the following beneficial effects:

[0028] The skull decompression connector designed in the present application can fix the skull to be repaired and the repair piece together to achieve the purpose of skull repair; at the same time, a tension spring is arranged on the side of the connector connected to the repair piece. When the patient's brain pressure increases, the compression and extension of the tension spring can be used to move the repair piece up and down, thereby achieving the effect of relieving brain tissue pressure.
