The embodiment of the utility model provides a restorer has easy operation, the higher advantage of work efficiency.
In order to achieve the above object, the embodiment of the present invention provides a repositor, which comprises a guide pin and an expansion device;
one end of the guide pin is a handheld end, and the other end of the guide pin is an insertion end;
the expansion device comprises an expansion piece and a driving part for driving the expansion piece to expand and contract, the expansion piece is arranged on the guide pin, and the driving part is arranged at the handheld end.
Compared with the prior art, when the device is used for fracture auxiliary reduction, the guide pin is firstly sent into a marrow cavity at the far fracture end under C-arm perspective monitoring, then the expansion piece is moved to a broken bone position needing reduction under the C-arm perspective monitoring by using the guide pin, then an operator inflates the expansion piece by controlling the air pump, the expansion piece gradually expands, the expansion piece is gradually filled in the marrow cavity of the fractured bone in the expansion process, at the moment, the broken bone can be restored and moved, after the C-arm perspective shows that the reduction effect is satisfactory, the reduction is maintained outside the hand of the operator, the restorer is withdrawn for marrow expansion operation, after the marrow is expanded to the target diameter, the expansion piece is sent to the bone fracture end through the guide pin again, the inflation reduction process after the marrow expansion is carried out again, the restorer is withdrawn after the C-arm perspective reduction is satisfactory, and the intramedullary nail is placed into the intramedullary nail through the guide pin. The whole operation is simple and convenient, the auxiliary effect is very convenient for the operator to reset the fracture, and the practicability is higher.
As an improvement of the above scheme, the expansion piece comprises an air bag, and the air bag is sleeved outside the guide pin;
the drive portion includes air pump and trachea, the trachea is fixed attached set up in the guide pin, the air pump passes through the trachea with the gasbag is connected.
As an improvement of the scheme, one end of the air pipe is connected with the air bag, the other end of the air pipe is connected with a quick connector, and the air pump is connected with the quick connector.
As an improvement of the scheme, the outer part of the air bag is wrapped with a hard glue layer.
The method has the following specific beneficial effects:
1. in order to facilitate daily maintenance and storage of the device, the integral structure of the driving part is arranged in a manner of being convenient to disassemble, wherein one end of the air pipe is connected with the air bag, the other end of the air pipe is connected with a quick connector, and the air pump is connected with the quick connector;
2. the outside parcel of gasbag is provided with the ebonite layer. The arrangement of the hard glue layer is convenient for the integral shaping of the expansion piece, so that the expansion process of the expansion piece can be more stable, the use and operation stability of the device is improved, and the practicability is stronger;

Referring to fig. 1 and fig. 2, wherein fig. 1 is a schematic structural diagram of an embodiment of the present invention, and fig. 2 is a schematic structural diagram of an expansion member in an embodiment of the present invention.
A restorer comprises a guide needle 1 and an expansion device 2. Wherein, one end of the guide pin 1 is a handheld end 3, and the other end is an insertion end 4. The expansion device 2 comprises an expansion piece 5 and a driving part for driving the expansion piece 5 to expand and contract, wherein the expansion piece 5 is fixedly arranged on the guide pin 1, and the driving part is arranged at the handheld end 3.
In this embodiment, the inflation member 5 includes a balloon, and the balloon is sleeved outside the guide pin 1. The drive division includes air pump 6 and trachea 7, and trachea 7 sets up on guide pin 1 along 1 length direction of guide pin, and fixed the attaching, and air pump 6 passes through trachea 7 and air bag connection.
Illustratively, when the device is used for fracture auxiliary reduction, a guide pin 1 is firstly sent into a marrow cavity at the far fracture end under C-arm perspective monitoring, then an expansion piece 5 is moved to a broken bone part needing reduction under C-arm perspective monitoring by using the guide pin 1, then an operator inflates the expansion piece 5 by operating an air pump 6, the expansion piece 5 gradually expands, the gradually filled disease is attached to the inside of the marrow cavity in the expansion process, the broken bone can be reset and moved at the moment, after the C-arm perspective has satisfactory reduction effect, the operator keeps reduction outside the body, withdraws from the restorer to perform marrow expanding operation, after the marrow is expanded to the target diameter, the expansion piece 5 is again sent to the bone broken end through the guide pin 1, and then performs the inflation reduction process after the marrow expanding again, and after the C-arm perspective reduction has satisfactory effect, the restorer is withdrawn and is placed into an intramedullary nail through the guide pin 1. The whole operation is simple and convenient, the auxiliary effect is very convenient for the operator to reset the fracture, and the practicability is higher.
