Abstract
The utility model is related to medical instruments field, more particularly to easily import extended type femoral bone cavitas medullaris file, file body and the installation connecting portion located at file body top including adapting to femoral bone cavitas medullaris interior shape, the contact surface of the file body middle and upper part and femoral bone cavitas medullaris is multilayer sawtooth waveforms, the lower surface level of the sawtooth waveforms unit each protruded, top sawtooth waveforms unit side surface is provided with the circular indicating pass through hole of insertion, the bottom of the file body is smooth taper surface, because the contact surface of file body middle and upper part and femoral bone cavitas medullaris designs for multilayer sawtooth waveforms, stock file is changed into compression to the shearing force of pulp cavity, the cancellous bone that pulp cavity is removed, more remain bone amount；The bottom of file body is that smooth taper surface is gradually narrowed, it is easy to while entering pulp cavity, reduces the resistance that pulp cavity file enters pulp cavity.
Description
Technical field
The utility model is related to medical instruments field, more particularly to easily imports extended type femoral bone cavitas medullaris file.
Background technology
Needed in Replacement of Hip Joint (THA) will type femoral bone end prosthesis insert femoral bone cavitas medullaris in, be allowed to femoral head and
Acetabular bone is coordinated, and realizes the operation purpose for recovering patient's hip joint movable function.Type femoral bone end prosthesis insertion femoral bone cavitas medullaris before,
Pulp cavity file is needed to use to carry out femoral bone cavitas medullaris moulding, to handle out consistent with type femoral bone end prosthesis in the pulp cavity of closing
Form, is easy to the implantation of type femoral bone end prosthesis.
Because femur is the long bone of closing, so, when carrying out moulding to femoral bone cavitas medullaris using pulp cavity file, it is necessary to consider
Easy importing, decompression, the factors such as many reservation bone amount of trying one's best.
Easily importing is in order to ensure file is when entering femoral bone cavitas medullaris, it is ensured that file position is correct, zero deflection；
Decompression：Because femoral bone cavitas medullaris is closed long bone, if the pressure that file is caused in implantation process is excessive, it can lead
The postoperative ratio lifting for occurring thromboembolism is caused, causes serious postoperative complication, severe patient even osteotomy；
Many reservation bone amount as far as possible：It is more to retain bone amount, it is that postoperative overhaul remains bone amount beneficial to postoperative Integrated implant.
Conventional pulp cavity file can not fully meet above-mentioned requirements, cause high surgical errors rate, dangerous height, increase operation
Difficulty, needing offer badly a kind of can realize the pulp cavity file of the demand.
Utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art easily to be led there is provided one kind
Enter, depressurize, the easy importing extended type femoral bone cavitas medullaris file of many reservation bone amount as far as possible.
The utility model is to be achieved by the following technical programs：
Easily import extended type femoral bone cavitas medullaris file, including adapt to femoral bone cavitas medullaris interior shape file body and located at file
The contact surface of the installation connecting portion on body top, the file body middle and upper part and femoral bone cavitas medullaris is multilayer sawtooth waveforms, each convex
The lower surface level of the sawtooth waveforms unit gone out, top sawtooth waveforms unit side surface is provided with the circular indicating pass through hole of insertion, the file
The bottom of knife body is smooth taper surface.
The connecting portion of installing includes setting in the middle part of the connecting pole and the neck located at opposite side located at side, the connecting pole
Limited location is recessed, and connection top end is provided with inclined mounting surface.
The beneficial effects of the utility model are：
Because the contact surface of file body middle and upper part and femoral bone cavitas medullaris designs for multilayer sawtooth waveforms, by stock file to pulp cavity
Shearing force is changed into compression, the cancellous bone that pulp cavity is removed, and more remains bone amount；The bottom of file body is light
Sliding taper surface is gradually narrowed, it is easy to while entering pulp cavity, reduces the resistance that pulp cavity file enters pulp cavity.
Brief description of the drawings
Fig. 1 is main structure diagram of the present utility model.
In figure：1. file body, 2. install connecting portion, 3. multilayer sawtooth waveforms, 4. circular indicating pass through hole, 5. taper surfaces, 6.
Connecting pole, 7. necks, 8. spacing depressions, 9. mounting surfaces.
Embodiment
In order that those skilled in the art more fully understand the technical solution of the utility model, below in conjunction with the accompanying drawings
The utility model is described in further detail with most preferred embodiment.
As illustrated, the utility model includes adapting to the file body 1 of femoral bone cavitas medullaris interior shape and located at file body
The contact surface of the installation connecting portion 2 on top, the file body middle and upper part and femoral bone cavitas medullaris is multilayer sawtooth waveforms 3, each protrusion
Sawtooth waveforms unit lower surface level, top sawtooth waveforms unit side surface be provided with insertion circular indicating pass through hole 4, the file
The bottom of body is smooth taper surface 5.
Because the contact surface of file body middle and upper part and femoral bone cavitas medullaris designs for multilayer sawtooth waveforms, by stock file to pulp cavity
Shearing force is changed into compression, the cancellous bone that pulp cavity is removed, and more remains bone amount；
The bottom of file body is that smooth taper surface 5 is gradually narrowed, it is easy to while entering pulp cavity, reduce pulp cavity file
Into the resistance of pulp cavity.
Femoral bone cavitas medullaris file near-end circle indicating pass through hole, effectively indicates that pulp cavity file enters the depth of pulp cavity, just in art
In indicating hole site selection femoral prosthesis model according to pulp cavity end correspondence is circular, to plurality of specifications femoral prosthesis is realized
Match somebody with somebody；
Femoral bone cavitas medullaris file coordinates clamping device to fix by the installation connecting portion on its top, and realizes operation, the company of installation
Socket part can be arranged as required to as various firm connected modes, it is preferred that installing connecting portion includes the connection located at side
Provided with spacing depression 8 in the middle part of post 6 and the neck 7 located at opposite side, the connecting pole, connection top end is provided with inclined mounting surface
9。
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as protection domain of the present utility model.
