Embodiment 1

[0032] The structure of Embodiment 1 of the present invention is as follows Figure 1 to Figure 4 As shown, the skull decompression connector in this embodiment includes two screws 1 and an elastic connector 2 connected between the two screws 1. The elastic connector 2 in this embodiment is a spring, and the spring is made of stainless steel wire or titanium The two ends of the elastic connector 2 are respectively connected with two screws 1, one screw is used for fixed connection on the bone window, and the other screw is used for fixed connection on the bone plate. The screw 1 includes a hollow external screw 11 and an external screw 12 with external threads. The hollow part of the external screw 11 has internal threads, and the internal screw 12 is threadedly connected to the hollow part of the external screw 11. The elastic connector 2 The end of the outer screw passes through the hollow part of the outer screw and is clamped between the inner screw 12 and the outer screw ...

Embodiment 2

[0040] The difference from Embodiment 1 of the present invention is that the connection method between the screw and the elastic connecting piece is different in this embodiment, and the connecting piece is used to connect the screw and the elastic connecting piece in this embodiment. The structure of the second embodiment of the present invention is as follows Figure 5 to Figure 6 As shown, the skull decompression connector of this embodiment further includes two connecting pieces 3, and each connecting piece 3 is provided with a screw through hole 31 and a connecting piece through hole 32, and the screw 1 is threaded on the screw through hole 31, The elastic connecting piece 2 is fixed on the connecting piece through hole 32, and the screw 1 is a cancellous bone screw. The rest of this embodiment is the same as that of Embodiment 1, and details are not repeated here.

Embodiment 3

[0043] The difference from Embodiment 1 of the present invention is that the connection between the screw and the elastic connector in this embodiment is different. The structure of Embodiment 3 of the present invention is as follows: Figure 7 As shown, in this embodiment, two ends of the elastic connecting member 2, ie, the spring, are respectively wrapped around two screws 1, and the screws 1 are cancellous screws. The rest of this embodiment is the same as that of Embodiment 1, and details are not repeated here.

[0044] When the patient undergoes craniotomy, the cut skull plate does not need to be discarded. The two ends of the elastic connection are wrapped around two screws respectively, and then the two outer screws are fixed on the bone window and the bone plate respectively, so that the The bone window and the bone plate are connected together.

[0045] In other embodiments of the present invention, the two ends of the elastic connecting piece 2 can also be provided...

Abstract

The invention discloses a cranial decompression connector, which is suitable for patients undergoing cranial surgery for decompression, and belongs to the technical field of medical devices. A skull decompression connector comprises two screws and an elastic connecting piece connected between the two screws, two ends of the elastic connecting piece are respectively connected with the two screws, one screw is used for fixed connection on a bone window, the other A screw is used to secure the connection to the bone plate. When the patient undergoes craniotomy, two screws are respectively fixed on the bone window and the bone plate, and the two ends of the elastic connecting band are respectively connected with the two screws, so as to connect the bone window and the bone plate together. As the pressure of the patient's brain tissue increases, the bone plate shifts to the outside and protrudes out of the bone window, reducing the intracranial pressure; the swelling of the patient's brain tissue subsides, and the intracranial pressure returns to the normal range. The plate automatically returns to its original position, and the bone plate gradually fuses with the bone window into a whole, realizing the self-repair of the skull and avoiding the second skull repair of the patient.

Description

technical field [0001] The invention relates to a cranial decompression connector, which is suitable for patients undergoing cranial surgery for decompression, and belongs to the technical field of medical devices. Background technique [0002] Most patients with traumatic brain injury, cerebral hemorrhage and various intracranial lesions require craniotomy. Patients with cerebral hemorrhage and tumor surgery often experience swelling of the brain tissue. At this time, the skull plate needs to be removed. Usually discarded, artificially created partial skull defect, usually called bone window, with the bone window of the skull defect, the swollen brain tissue can protrude out of the bone window when the pressure increases, so as to reduce the intracranial pressure and reduce the important factors in the brain. The degree of tissue compression, especially in patients with traumatic brain injury, often has severe brain tissue swelling, and it is even more necessary to remove t...
