Description

磨骨钻 技术领域
本发明涉及医疗器械，尤其涉及一种磨骨钻。
背景技术
磨骨钻是用于颌角肥大矫正术、颧骨降低、颧弓降低、鼻背基底缩窄、驼峰鼻矫正、眉弓降低、颏缩短等整容手术的常用器械。磨骨钻的常用操作方式是通过隐蔽部位的皮肤切口伸入钻杆，利用钻杆的旋转切割打磨骨骼，上述操作过程中，存在以下几个问题：
磨骨钻的钻杆转动过程中容易与皮肤切口接触，容易造成切口磨损，因此需通过其他器械拉住皮肤切口，从而避免接触；磨骨钻的钻杆转动需要手动控制磨削深度，避免钻杆的钻头旋入骨骼中。
申请号201420319429.2的实用新型涉及一种微创取骨器，包括套筒、穿设在套筒中的连杆及连接在连杆的前端头的磨钻头，连杆包括实心段和空心段，磨钻头后端内部有和连杆空心段的空心体连通的空腔，磨钻头上有和空腔连通的通孔，连杆的空心段设有若干和空心体连通的槽孔，套筒和连杆之间设有将槽孔围在套筒的进水段的前、后轴封件，套筒的进水段设有进水口，前轴封件前方的套筒和连杆之间形成出料通道，前轴封件前方的套筒上设有和出料通道连通的出料口，出料口上设有和负压抽吸装置相连的骨屑收集容器。该微创取骨器需要设置出料通道实现出料，连杆和套筒之间的间隙较大，且连杆具有空心段，因此套筒的尺寸较大，伸入小切口难度较大，且由于间隙较大，连杆转动的稳定性不高。
发明内容
本发明的目的在于克服现有技术中存在的上述不足，而提供一种磨骨钻。该磨骨钻可以避免钻杆选择磨损皮肤切口并且可以避免钻杆的钻头旋入骨骼中，且操作更加方便，钻杆转动的稳定性高。
本发明解决上述问题所采用的技术方案是：
一种磨骨钻，包括电钻以及钻杆，钻杆夹持固定于电钻的一端，其特征在于：所述钻杆采用麻花钻，所述电钻上固定有用于套设麻花钻的套接件，套接件具有一段套管，套管的内径和麻花钻的外径采用间隙配合，所述麻花钻插入套管，且麻花钻钻头从套管的一端端口伸出。
进一步，作为优选，套接件内设用于存储碎屑的空腔。
进一步，作为优选，套接件上开设有出料口。
进一步，作为优选，套接件内设用于存储碎屑的空腔，所述出料口连接至空腔。
进一步，作为优选，出料口连通至吸收管的一端，所述吸收管的另一端连通至负压设备。
进一步，作为优选，套管的一端端口相对套管的轴线呈倾斜设置。
本发明与现有技术相比，具有以下优点和效果：
(1)磨骨钻通过在麻花钻外套设套管，使得套管隔离切口皮肤和麻花钻的侧壁，避免了麻花钻对皮肤切口的磨损，操作更加方便；
(2)利用麻花钻的钻头刃部磨削骨骼，并通过螺旋槽和套管的内壁形成螺旋状的通道输出碎屑，有利于快速排出碎屑；
(3)利用麻花钻的钻头刃部磨削骨骼，麻花钻的其余部位被套设于套管内，麻花钻磨削的深度得到控制，麻花钻不会钻入骨骼内，保证了操作的安全性；
(4)由于套管本身不转动，套管可以摆动牵拉皮肤切口，改变麻花钻的钻头的磨削位置，以适应更大范围的磨削需求；
(5)套管的内径和麻花钻的外径采用间隙配合，套管内壁和麻花钻外壁之间间隙较小，不仅有利于形成螺旋状的通道，且套管有助限制钻杆的偏移，钻杆转动的稳定性更高。

具体实施方式
下面结合附图并通过实施例对本发明作进一步的详细说明，以下实施例是对本发明的解释而本发明并不局限于以下实施例。
实施例一
参见图1-图2，本实施例磨骨钻，包括磨骨钻，包括电钻1以及钻杆，钻杆夹持固定于电钻1的一端，所述钻杆采用麻花钻2，所述电钻1上固定有用于套设麻花钻2的套接件3，套接件3具有一段套管31，套管31的内径和麻花钻2的外径采用间隙配合，所述麻花钻2插入套管31，且麻花钻2钻头22从套管31的一端端口伸出。套接件3上开设有出料口33。套接件3内设用于存储碎屑的空腔32，所述出料口33连接至空腔32。出料口33连通至吸收管5的一端，所述吸收管5的另一端连通至负压设备。通过负压将出料口33的碎屑吸出。
需要说明的是：电钻1采用现有钻夹头实现固定于电钻1上，由于钻夹头为电钻1行业的常规结构，非本发明的设计点，故此不做赘述。
本实施例磨骨钻具有以下优点：
(1)磨骨钻通过在麻花钻2外套设套管31，使得套管31隔离切口皮肤和麻花钻2的侧壁，避免了麻花钻2对皮肤切口的磨损，操作更加方便；
(2)利用麻花钻2的钻头22刃部磨削骨骼，并通过螺旋槽21和套管31的内壁形成螺旋状的通道4输出碎屑，有利于快速排出碎屑；
(3)利用麻花钻2的钻头22刃部磨削骨骼，麻花钻2的其余部位被套设于套管31内，麻花钻2磨削的深度得到控制，麻花钻2不会钻入骨骼内，保证了操作的安全性；
(4)由于套管31本身不转动，套管31可以摆动牵拉皮肤切口，改变麻花钻2的钻头22 的磨削位置，以适应更大范围的磨削需求；
(5)套管31的内径和麻花钻2的外径采用间隙配合，套管31内壁和麻花钻2外壁之间间隙较小，不仅有利于形成螺旋状的通道4，且套管31有助限制钻杆的偏移，钻杆转动的稳定性更高。
实施例二
参见图3-图4，本实施例磨骨钻，包括磨骨钻，包括电钻1以及钻杆，钻杆夹持固定于电钻1的一端，所述钻杆采用麻花钻2，所述电钻1上固定有用于套设麻花钻2的套接件3，套接件3具有一段套管31，套管31的内径和麻花钻2的外径采用间隙配合，所述麻花钻2插入套管31，且麻花钻2钻头22从套管31的一端端口伸出。套接件3上开设有出料口33。套接件3内设用于存储碎屑的空腔32，所述出料口33连接至空腔32。出料口33连通至吸收管5的一端，所述吸收管5的另一端连通至负压设备。通过负压将出料口33的碎屑吸出。套管31的一端端口311相对套管31的轴线呈倾斜设置。采用这种结构，使得麻花钻2的侧边的切削刃23外露，可以利用麻花钻的侧边的切削刃23进行斜向磨削。
本说明书中所描述的以上内容仅仅是对本发明所作的举例说明。本发明所属技术领域的技术人员可以对所描述的具体实施例做各种各样的修改或补充或采用类似的方式替代，只要不偏离本发明说明书的内容或者超越本权利要求书所定义的范围，均应属于本发明的保护范围。
