数据深层嵌套时使用splice视图仍未更新

[haoxl3]

initData() {
    return {
        allTabs: [
            {
                "parent": "胃癌",
                "isOpen": false,
                "children": [
                    {
                        "icd_name": "胃恶性肿瘤",
                        "icd_code": "C15.900"
                    },
                    {
                        "icd_name": "胃良性肿瘤",
                        "icd_code": "C16.900"
                    }
                ]
            },
            {
                "parent": "肺炎",
                "isOpen": false,
                "children": [
                    {
                        "icd_name": "新冠性肺炎",
                        "icd_code": "C16.910"
                    }
                ]
            }
        ]
    }
},
openTabHandle({item, index, pIndex}) {
    // item = {icd_name: '胃恶性肿瘤', icd_code: 'C15.900'}
    // index = 0; pIndex = 0;
    item.showReason = !item.showReason
    this.data.splice('allTabs[pIndex].children', [index, 1, item]);
    console.log(this.data.get('allTabs');
}

如上代码所示，在openTabHandle方法中修改allTabs.children里面的属性，打印出数据确实变化了，但视图却没更新，使用深克隆重新给allTabs赋值视图同样不刷新。请问如何让视图刷新？
