Problems solved by technology

The existing technology only uses bolts or wires to connect the bone flap and the skull with a splint. The lower end plate of the splint should be placed inside the skull, and it will stay in the brain to contact the meninges later, leaving a potential safety hazard. ; or use L-shaped nails to fix the reset bone flap. When the nail is clamped with the bone flap and the skull, it is very easy to have a deviation at the seam between the bone flap and the skull, which will affect the reset accuracy of the bone flap. Repeatedly adjust the gap between the bone flap and the skull. The position of the fixed nail is prone to loosening, resulting in unstable fixation, poor joint strength, and difficulty in shaping, which can easily lead to poor compatibility or even necrosis of the skull tissue in the later stage; The process is complex and requires high clinical experience for doctors

Embodiment 1

[0037] Refer to attached figure 1 , Figure 4 , Figure 5 with Image 6 As shown, according to the size and shape of the patient's defect, the doctor made a bionic skull bone flap 7 that fit the patient's defect or directly used an autologous bone flap 7. Grooves were ground on the bone flap 7 along the vertical direction of its interface and Put the sinking screw 5 into the bone flap 7 in advance and tighten it, the transfer device 4 will hold the bone flap 7, and the corrugated frame 1 will be sucked tightly above the defect 81 of the skull 8 through the sucking device 2, and the corrugated frame 1 The transfer device 4 that holds the bone flap 7 can be driven to move in a plane through the adjustment device 3, and the transfer device 4 that holds the bone flap 7 can also rotate and move up and down on the corrugated frame 1 and be compressed by the compression cover 41, The bone flap 7 is accurately placed in the defect 81 of the skull 8 to align and stabilize its positi...

Embodiment 2

[0040] On the basis of embodiment one, refer again Figure 7 As shown, the sinking screw 5 is made of titanium alloy material, and the sinking screw 5 may include: a clamping sleeve 51, a rotating lever 52, a convex and sliding dial 53, a spiral connecting column 54, a horizontal bolt locking rod 55, and a bolt expanding The tip 56 and the clamp sleeve 51 are pressed in the groove formed by the bone flap 7. The lower half of the clamp sleeve 51 is a cylinder and the upper half is a square body, so as to ensure that the clamp sleeve 51 is clamped in the bone flap 7 and will not rotate. ; The inside of the clamping sleeve 51 is a threaded hole, the rotary rod 52 is concentric with the axis of the inner hole of the clamping sleeve 51, the rotary rod 52 is rotated and blocked and connected to the clamping sleeve 51, and the rotary rod 52 is a circular rod shape, the rod of the rotary rod 52 is milled with a long bar hole, the outer side of the rotary rod 52 is a cap shape, and the...

Abstract

The invention provides a skull resetter with a splint, which relates to the field of medical devices and includes: a corrugated frame, used to support the defect of the skull; a suction device, used to tighten the corrugated frame and the defect of the skull; The adjusting device connects the corrugated frame with the suction device, and the adjusting device is used to make the corrugated frame move and lock on the surface of the suction device; Hold the bone flap and place the bone flap in the defect of the skull; the countersunk screw is used to connect the bone flap to the middle of the reduced section of the skull; the splint buckle is used to cover the counterscrew and form the bone flap with the skull connect. The cranial reset device with a splint provided by the present invention uses a corrugated frame to support and hold a transfer device for sucking and holding a bone flap for three-coordinate movement adjustment and rotation adjustment, which facilitates the stable reset of the bone flap and is connected and fixed by sinking screw and splint buckle .

Description

technical field [0001] The invention relates to a skull reducer with a splint. Background technique [0002] Today, craniotomy is a common procedure compared to neurosurgery. Craniotomy can relieve cerebral edema, stop bleeding, repair blood vessels, treat brain diseases such as epilepsy or remove brain tumors. The human skull is made of skull, which is hard and covers and protects the brain tissue. After craniotomy, sometimes the bone flap removed from the skull cannot be replanted in situ immediately. It can be preserved by autologous subcutaneous embedding or directly frozen for a period of time before replantation. Usually, the autologous skull is replanted. Implantation belongs to the best repair skull. With the improvement of CT three-dimensional reconstruction technology, titanium alloy or polyether ether ketone (PEEK) materials can be used to make skull restorations with defect shapes. After the edges are polished and smooth, they can be placed at the bone window ...
