Abstract
It the utility model is related to protection device when bone drill and MED operate in operation, specifically a kind of double-jacket tube formula revoling tube.One end of described sleeve pipe is provided with handle, and the other end is protection end, and the port end face of the protection end is extended with for inclined plane or forward protection board in end along tube wall；Described sleeve pipe includes the two sleeve pipe I and sleeve pipe II being mutually socketed；Described sleeve pipe I is outer tube, and sleeve pipe II is inner sleeve；Hollow drill is provided with sleeve pipe II.This programme uses double-jacket tube formula, can staggeredly be rotated between two sleeve pipes, carry out multi-faceted protection.
Description
Technical field
It the utility model is related to protection device when bone drill and MED operate in operation, specifically a kind of double-jacket tube formula
Revoling tube.
Background technology
In the medical operating of orthopaedics, it is often necessary to use bone drill to be cut to the bone at some positions.But it is
Prevent from destroying neighbouring human body its hetero-organization, and need that bone drill is carried out to block protection.In existing apparatus, without can be with
The bone sleeve pipe pipe of partial occlusion is carried out for operative site.And in some significant points, due to multiple sides at drill bit position
To when being required to block protection, existing Medical Devices can not meet.Therefore certain difficulty is brought to operation, is using bone
Needs are extremely careful during brill, while larger wound is also easily caused to patient, are unfavorable for physical recovery.
The content of the invention
It is to solve the problems, such as that prior art is present that the utility model, which is exactly, and devises a kind of double-jacket tube formula revoling tube,
Solve the demand that bone drill needs partial occlusion in operation, and it is easy to use, improve the security of operation.
The technical solution of the utility model is：A kind of double-jacket tube formula revoling tube, one end of described sleeve pipe are provided with handle, separately
One end is protection end, and the port end face of the protection end is extended with for inclined plane or forward protection board in end along tube wall；Institute
Stating sleeve pipe includes the two sleeve pipe I and sleeve pipe II being mutually socketed；Described sleeve pipe I is outer tube, and sleeve pipe II is inner sleeve；Sleeve pipe II
It is interior to be provided with hollow drill.
The tube wall length of described sleeve pipe I is more than or equal to the length of sleeve pipe II；And in the port of protection end in same position.
The outer tube wall of described sleeve pipe is provided with graduation mark.
The handle of described sleeve pipe is provided with the station location marker with protection board or beveled top end position correspondence.
The smooth fillet that the corner of the protection board for the benefit of rotates, the end of protection board is circular arc end face.
Described sleeve pipe I and sleeve pipe II are provided with the fastener for being used for fixing relative position in handle position.
The fastener is fixing bolt.
The beneficial effects of the utility model can be drawn by such scheme：Due to being provided with bone drill protective case, can be directed to
The operation of different parts needs to be oriented to block.This programme uses double-jacket tube formula, can staggeredly rotate, enter between two sleeve pipes
The multi-faceted protection of row.Simultaneously because tip shape is may also set up at the top of sleeve pipe, for being helped when bore position is easily movable
In positioning.The handle of sleeve pipe is provided with station location marker with protection board or beveled top end position correspondence, can allow the angle of rotation
It is clear.Sleeve pipe I and sleeve pipe II are provided with the fastener for being used for fixing relative position in handle position, can cause two sleeve pipes
It can be accurately positioned, avoid producing relative slide in operation.This programme is simple in construction, easy to use, solves bone drill and is performing the operation
The middle demand for needing partial occlusion, be advantageous to improve the security of operation.This programme can in drilling from protect.Also make simultaneously
For the sleeve pipe used outside mirror, can under mirror direct-view by sleeve rotating to needing most the position of blocking protection.
As can be seen here, the utility model has substantive distinguishing features and progress compared with prior art, its beneficial effect implemented
Fruit is also obvious.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of sleeve pipe I when end face is inclined plane；
Fig. 3 is the structural representation of sleeve pipe II when there is protection board end face；
Wherein, 1 is handle, and 2 be sleeve pipe I, and 3 be sleeve pipe II, and 4 be manual fastening bolt, and 5 be inclined plane, and 6 be protection board.
Embodiment
In order to more fully understand the utility model, embodiment of the present utility model is explained in detail below in conjunction with the accompanying drawings.
Embodiment：As shown in Figure 1, 2, a kind of double-jacket tube formula revoling tube, one end of described sleeve pipe are provided with handle
1, the other end is protection end；The port end face of the protection end is inclined plane 5.Described sleeve pipe includes two sleeve pipes being mutually socketed
I2 and sleeve pipe II 3；Described sleeve pipe I 2 is outer tube, and sleeve pipe II 3 is inner sleeve；Hollow drill is provided with sleeve pipe II 3.Described sleeve pipe
I 2 tube wall length is more than the length of sleeve pipe II 3.Graduation mark is equipped with the outer tube wall of described sleeve pipe.The handle 1 of described sleeve pipe
It is provided with the station location marker with beveled top end position correspondence.Described sleeve pipe I2 and sleeve pipe II 3 are provided with handle position to be used to fix
The manual fastening bolt 4 of relative position.
In addition, as shown in figure 3, described sleeve pipe can also be is provided with what is extended forward along tube wall on the end face of its protection end
Protection board 6, the smooth fillet that the corner of the protection board 6 for the benefit of rotates, the end of protection board 6 is circular arc end face,
Remaining structure is consistent with such scheme.
It is to be also not limited to the example above, this skill to limitation of the present utility model, the utility model that described above, which is not,
The variations, modifications, additions or substitutions that the those of ordinary skill in art field is made in essential scope of the present utility model, also should
Belong to the scope of protection of the utility model.
