Detailed Description

The present invention will be described in further detail with reference to the following drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

As shown in fig. 1-4, an embodiment of the present invention provides a soft tissue dilation protector, including a chute seat 1, a rotating component 2, a fixed component 3, a movable module 4, and a matching inner sleeve 5, wherein two ends of the chute seat 1 are respectively connected to the rotating component 2 and the movable module 4, the fixed component 3 is used for connecting the chute seat 1 to the rotating component 2, the chute seat 1 and the movable module 4 are connected to form a channel 6, the size of the channel 6 can be adjusted by the chute seat 1 and the rotating component 2, the rotating component 2 is provided with an inner diameter matched with the size of the sleeve 5, the chute seat 1 is connected to the movable module 4 by a groove 11, the connecting module 4 is preferably provided with 6 blocks, the surfaces of the chute seat 1 and the rotating component 2 are provided with grooves 11, the size of the groove 11 is matched with the size of the fixed component 3, the fixed component 3 is fixed by screws or the like after being placed in the groove 11, passageway 6 be by 6 movable module 4 constitutions, passageway 6's size accessible rotary part 2 adjustment, rotary part 2's side has scale 21, scale 21 can set up 3mm, 5mm, 8mm, 10 mm's scale, it is minimum diameter to show the passageway when 3 mm's scale 21, it is the biggest to show the passageway when 10 mm's scale 21 is last, rotary part 2 lateral surface is provided with antiskid screw thread 22 when being used for the rotation, adjust the size of passageway 6 after, just select assorted sleeve 5, put into rotary part 2's inner warp 23 with the sleeve pipe, internal thread 231 and sheathed tube external screw thread 51 through rotary part internal diameter are connected.

When the soft tissue expansion protector is used, the size of the channel 6 is adjusted, the sleeve 5 is placed into the inner diameter 23 of the rotating part 2, the inner thread 231 of the inner diameter 3 of the rotating part 2 is connected with the outer thread 51 of the sleeve, then a doctor selects a drill bit matched with the sleeve 5 to start working, and after drilling is completed, the protector can be taken away.
