Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially a kind of porous autologous bone marrow transplantation puncture needle.
Background technology
Fracture of femur disunion or delayed union are common complications clinically, and treatment can cause fragmentation of internal fixation objects not in time, needs second operation, extend the hospital stays, increase medical expense, cause joint function disturbance even disabled.By autologous bone marrow transplantation in nonunion position, union of fracture can be promoted, but the method for application Wicresoft carries out the cleaning of fracture site and Iliac bone grafting needs a kind of puncture needle, but existing puncture needle does not possess cleaning scar tissue and autogenous bone marrow blood is imported the function at fracture site place.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind ofly can clear up scar tissue and autogenous bone marrow blood can be imported to the porous autologous bone marrow transplantation puncture needle at fracture site place.
In order to solve the problems of the technologies described above, this utility model comprises the revoling tube of inner hollow and has positioning and guiding effect and intert the nook closing member in revoling tube, described revoling tube front end is formed with the external screw thread for removing scar tissue between disunion fracture site, tail end is provided with the boss for being connected with electric drill, the external screw thread place of described revoling tube is provided with multiple through hole be connected with revoling tube inside, described nook closing member forward tip is formed with triangular pyramid, and tail end can be connected with electric drill special.
Described revoling tube length is 200 ㎜, and described externally threaded length range is at 10 ㎜-30 ㎜, and the large footpath of this external screw thread is 8.5 ㎜, and external screw thread path is 6.5 ㎜, and this external screw thread pitch is 2 ㎜.
Described revoling tube internal diameter is 3 ㎜, and described nook closing member external diametrical extent is at 1 ㎜-3 ㎜.
The beneficial effects of the utility model are: in this utility model, nook closing member serves positioning and guiding effect, nook closing member can be inserted in disunion fracture site place and guide revoling tube to insert this place, revoling tube can be removed scar tissue between disunion fracture site under the drive of electric drill, after extracting nook closing member, marrow blood enters revoling tube inside by through hole and spreads around bone grafting, makes marrow blood enter into nonunion position.In addition, this utility model is simple and practical.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model porous autologous bone marrow transplantation puncture needle.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail:
See Fig. 1, this utility model comprises the revoling tube 1 of inner hollow and has positioning and guiding effect and intert the nook closing member 2 in revoling tube 1, described revoling tube 1 front end is formed with the external screw thread 11 for removing scar tissue between disunion fracture site, tail end is provided with the boss 12 for being connected with electric drill, external screw thread 11 place of described revoling tube 1 is provided with multiple through hole 13 be connected with revoling tube 1 inside, described nook closing member 2 forward tip is formed with triangular pyramid, tail end can be connected with electric drill special, nook closing member 2 can be made to pierce disunion fracture site place or extract by electric drill special, the design of triangular pyramid makes nook closing member 2 more firm when inserting.
Preferably, described revoling tube 1 length is 200 ㎜, and the length range of described external screw thread 11 is at 10 ㎜-30 ㎜, and the large footpath of this external screw thread 11 is 8.5 ㎜, and external screw thread 11 path is 6.5 ㎜, and this external screw thread 11 pitch is 2 ㎜.
Preferably, described revoling tube 1 internal diameter is 3 ㎜, and described nook closing member 2 external diametrical extent is at 1 ㎜-3 ㎜.
During use, nook closing member 2 is inserted in disunion fracture site place under the drive of electric drill special, revoling tube 1 also inserts disunion fracture site place along nook closing member 2, revoling tube 1 can be removed scar tissue between disunion fracture site under the drive of electric drill, after removing, marrow blood is permeable to around bone grafting, after extracting nook closing member 2 with electric drill special again, multiple through holes 13 on revoling tube 1 can make marrow blood better to surrounding disperse, thus do not need adjustment puncture needle direction can realize spreading to surrounding different directions, even if the inside-fixtures such as the fracture marrow nail that on revoling tube 1, the design of external screw thread 11 can make it contact still can spread marrow blood along gullet, thus reduce injection required time, reduce marrow blood and solidify risk.
In sum, content of the present utility model is not limited in the above-described embodiment, and those skilled in the art can propose other embodiment within technological guidance's thought of the present utility model, but these embodiments are all included within scope of the present utility model.
