Description
Technical field
This utility model relates to medical instruments field, is specifically related to a kind of pressurized pilot device.
Background technology
Wicresoft's osteopathy is a kind of modern Fracture internal fixaiion technology, it adopts closed fracture resetting technique, and fixedly maintain fracture reduction with the screw of pressurization, promote fracture recovering, surgical exposure and soft tissue extent of exfoliation are reached minimize, the blood decreased skin, periosteum, sclerite etc. are organized supplies to destroy, and can improve union of fracture rate, and reduce the incidence rate of the such as complication such as infection or nonunion.Pressurized pilot device is in order to drill bit processing pressurization hole and provide guide effect, and after a procedure, processing and the pressurization hole that goes out can not ensure parallel with lock hole, brings inconvenience to the use in later stage to existing pressurized pilot device.
Utility model content
The purpose of this utility model is to provide a kind of pressurized pilot device, can utilize adjacent lock hole to determine position and the machine direction in pressurization hole, the locking direction of lock hole can be made parallel with the compression aspect in pressurization hole, facilitate the use in later stage.
For achieving the above object, the technical scheme that this utility model adopts is: comprise locking guide, pressurized pilot part, connecting rod and direction control device, locking guide and pressurized pilot part be arranged in parallel, direction control device rotation type is located on locking guide, one end of connecting rod connects pressurized pilot part, and the other end of connecting rod is flexibly connected direction control device.
Preferably, described direction control device rotation type is located on the end of locking guide, direction control device comprises guide pin bushing and locking piece, guide pin bushing is the column structure of hollow, one end external diameter of guide pin bushing is less than the internal diameter of end, and one end of guide pin bushing is stretched in end, and locking piece stretches into the inside of guide pin bushing and the inner chamber along guide pin bushing moves from the other end of guide pin bushing, the outer wall from guide pin bushing that connecting rod slides is through guide pin bushing, and connecting rod is positioned at the vertical below of locking piece.
Preferably, described locking piece is lock screw.
Preferably, described direction control device also comprises lock nut, and lock nut to be placed in guide pin bushing and to be set on locking piece.
After adopting technique scheme, this utility model has following good effect:
(1) pressurized pilot device of the present utility model, sets up locking guide, and locking guide is position and lock hole, is be arranged in parallel by locking guide and pressurized pilot part, can ensure that the compression aspect in pressurization hole is parallel with the locking direction of lock hole;
(2) pressurized pilot device of the present utility model is provided with direction control device, connecting rod slides through the guide pin bushing in direction control device, guide pin bushing can rotation, connecting rod is driven to rotate while guide pin bushing rotation, thus driving pressurized pilot part can rotate around locking guide, connecting rod is by the length through guide pin bushing simultaneously, controls the distance between pressurized pilot part and locking guide, thus meet the process requirements in different distance, pressurization hole, diverse location place, use flexibility ratio high.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.
As shown in Figure 1-2, be pressurized pilot device of the present utility model, comprise locking guide 1, pressurized pilot part 2, connecting rod 3 and direction control device 4.Locking guide 1 is for the Working position in position and lock hole, and pressurized pilot part 2 is for locating the Working position in pressurization hole, and locking guide 1 be arranged in parallel with pressurized pilot part 2.Direction control device 4 rotation type is located on locking guide 1, and one end of connecting rod 3 connects pressurized pilot part 2, and the other end of connecting rod 3 is flexibly connected direction control device 4, and connecting rod 3 is all vertical with pressurized pilot part 2 with locking guide 1.Direction control device 4 is for controlling pressurized pilot part 2 and the relative position locking guide 1.
Direction control device 4 is positioned on the end 11 of locking guide 1, and direction control device 4 comprises guide pin bushing 41, locking piece 42 and lock nut 43.Guide pin bushing 41 column structure in hollow, one end external diameter of guide pin bushing 41 is less than the internal diameter of end 11, and one end of guide pin bushing 41 is stretched in end 11, thus guide pin bushing 41 metastablely can be positioned on end 11 and ensure that guide pin bushing 41 can rotation.Locking piece 42 stretches into the inside of guide pin bushing 41 from the other end of guide pin bushing 41, and locking piece 42 can move along the inner chamber of guide pin bushing 41, and locking piece 42 is lock screw.The outer wall from guide pin bushing 41 that connecting rod 3 slides is through guide pin bushing 41, and connecting rod 3 is positioned at the vertical below of locking piece 42, and locking piece 42 can move to the position offseted with connecting rod 3 by intracavity in guide pin bushing 41, makes locking piece 42 lock connecting rod 3.Lock nut 43 to be placed in guide pin bushing 41 and to be set on locking piece 42, and lock nut 43 is for coordinating with locking piece 42, and the traffic direction of limiting lock locking member 42.
When pressurized pilot device of the present utility model uses, locking guide 1 is fixed on lock hole place, unscrew locking piece 42, stretching connecting rod 3 or rotation guide pin bushing 41, make pressurized pilot part 2 be positioned at the pressurization hole place of needs, the locking direction this ensures that thering lock hole is completely parallel with the compression aspect in pressurization hole.
To one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection domain that this utility model requires.
