Abstract
Guide pin extracting apparatus in marrow of the present utility model, comprise handle main body and lock handle, wherein handle main body and lock handle are flexibly connected by the round pin in handle main body, handle main body arranges guide groove, guide groove is positioned at the top of above-mentioned round pin, lock handle arranges eccentric lobe in the link position upper end with round pin, and eccentric lobe is rotated in guide groove with lock handle.Guide pin in marrow can be extracted by this utility model fast and effectively, easy to operate, simple and reasonable for structure, has effectively saved the time of clinical operation.
Description
Technical field
This utility model belongs to the operating theater instruments outside input human body, is specifically related to guide pin extracting apparatus in a kind of marrow.
Background technology
In the operation of orthopaedics intramedullary pin, need to complete boring by inserting guide pin in marrow, expand marrow, insert the operations such as tail cap, but after completing operation technique, because guide pin diameter in marrow is comparatively thin when guide pin takes out in marrow, need to extract by instrument.In existing marrow, guide pin extracting apparatus is that double rocking lever form completes extraction function, and matable assembly is more, and operability is poor and use is inconvenient, and fault rate is higher, and Clinical practice also exists drawback, haves much room for improvement.
Summary of the invention
The purpose of this utility model is to provide guide pin extracting apparatus in a kind of marrow.
For reaching above object, this utility model by the following technical solutions:
Guide pin extracting apparatus in marrow of the present utility model, comprise handle main body and lock handle, wherein handle main body and lock handle are flexibly connected by the round pin in handle main body, handle main body arranges guide groove, guide groove is positioned at the top of above-mentioned round pin, lock handle arranges eccentric lobe in the link position upper end with round pin, and eccentric lobe is rotated in guide groove with lock handle.
Advantage of the present utility model and good effect as follows:
In marrow of the present utility model in guide pin extracting apparatus, by holding twist-lock handle, change the spacing between lock handle eccentric lobe and handle main body, thus realize the effective clamping to guide pin in marrow, and then extracted.It is more that this utility model solves matable assembly in existing extractor, operability is poor and use is inconvenient, and the problem that fault rate is higher, can extract guide pin in marrow fast and effectively, easy to operate, simple and reasonable for structure, effectively save the time of clinical operation.
Accompanying drawing explanation
Fig. 1 is the structural representation of guide pin extracting apparatus in marrow of the present utility model;
Fig. 2 is the structural representation of handle main body in guide pin extracting apparatus in marrow of the present utility model;
Fig. 3 is the structural representation of lock handle in guide pin extracting apparatus in marrow of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the technical solution of the utility model is described in detail:
As shown in Figure 1 to Figure 3, guide pin extracting apparatus in marrow of the present utility model, comprise handle main body 1 and lock handle 2, wherein handle main body and lock handle are flexibly connected by the round pin 3 in handle main body, handle main body is arranged guide groove 4, guide groove is positioned at the top of above-mentioned round pin, and lock handle arranges eccentric lobe 5 in the link position upper end with round pin, and eccentric lobe is rotated in guide groove with lock handle.In marrow, guide pin should be placed in guide groove when extracting, and blocks by the eccentric lobe in lock handle, and when holding lock handle, guide pin in marrow to the direction motion leaving guide groove, thus is extracted by eccentric lobe.
In marrow of the present utility model in guide pin extracting apparatus, by holding twist-lock handle, change the spacing between lock handle eccentric lobe and handle main body, thus realize the effective clamping to guide pin in marrow, and then extracted.It is more that this utility model solves matable assembly in existing extractor, operability is poor and use is inconvenient, and the problem that fault rate is higher, can extract guide pin in marrow fast and effectively, easy to operate, simple and reasonable for structure, effectively save the time of clinical operation.
