Abstract
The utility model discloses a kind of bone-cement type hip replacement femoral myelocavity files, it includes a file body, the blade for being laid with multiple drops on the front and back of the file body, multiple small sawtooth are laid on the both sides vertical direction of the file body, the end of the file body is embedded with a file interface that connection is matched with the dedicated Myelocavity file connecting rod of SuperPATH approaches；The file interface includes an interface body, one is offered in the interface body for being embedded the groove of the Myelocavity file connecting rod, the groove is oval, and the end of the interface body is connected with a stent.Femoral myelocavity file meets the needs through the minimally invasive approach row hip replacement surgeries of SuperPATH, while notch is not expanded, makes full use of spatium intermusculare, while can be good at getting out femoral bone cavitas medullaris again, reaches the needs of bone-cement type hip replacement.Elderly patient is enable to be replaced through the approach row bone-cement type hip prosthesis, it being capable of faster rehabilitation.
Description
Technical field
The utility model is related to the field of medical instrument technology more particularly to a kind of bone-cement type hip replacement femoral bone cavitas medullaris
File.
Background technology
At present, the common approach of hip replacement surgery is broadly divided into traditional approach and minimally invasive approach, SuperPATH
(Supercapsular Percutanously Assisted Total Hip) full name is minimally invasive for auxiliary Percutaneous Techniques
Replacement of total hip.The minimally invasive approaches of SuperPath are the approaches of wound minimum in current all technologies, pass through gluteus minimus in art
Enter with pyriformis gap, almost retain all capsular ligament and muscle, avoiding needs in traditional artificial replacement of total hip
The defects of cutting off hip joint Surrounding muscles makes patient is postoperative faster rehabilitation and can recover daily routines function.It is domestic clinical in
Start within 2014 using the technology.
Prosthese used in joint replacement is broadly divided into bone-cement type prosthese and bion prosthese two types at present, and bion is false
Body is suitable for the preferable patient of sclerotin condition, and bone-cement type prosthese is suitable for the poor gerontal patient of osteoporosis, sclerotin condition
In hip replacement surgery, the implantation of femoral prosthesis needs to use femoral myelocavity file：It is driven by bone hammer
Active force is longitudinally acted on femoral bone cavitas medullaris by device, is completed pulp cavity and is prepared.At present still without the bone-cement type hip suitable for the approach
Joint replacement femoral myelocavity file.Therefore it can be only done the displacement of bion prosthese at present through approach progress joint replacement, it can not
Carry out the displacement of bone-cement type prosthesis handle.
Utility model content
The utility model is in view of the problems of the existing technology and insufficient, provides a kind of new bone-cement type hip joint and puts
Change femoral myelocavity file.
The utility model is to solve above-mentioned technical problem by following technical proposals：
The utility model provides a kind of bone-cement type hip replacement femoral myelocavity file, and feature is, including a file
Body, the blade for being laid with multiple drops on the front and back of the file body, cloth on the both sides vertical direction of the file body
Equipped with multiple small sawtooth, the end of the file body is embedded with one and matches company with the dedicated Myelocavity file connecting rod of SuperPATH approaches
The file interface connect；
The file interface includes an interface body, and one is offered in the interface body for being embedded the recessed of the Myelocavity file connecting rod
Slot, the groove is oval, and the end of the interface body is connected with a stent.
It is preferred that the file body is equably laid with those blades on the front and back.
It is preferred that those small sawtooth are equably laid on the both sides of the file body.
On the basis of common knowledge of the art, above-mentioned each optimum condition, can be combined to get the utility model respectively compared with
Good example.
The positive effect of the utility model is：
The utility model designs the bone-cement type hip replacement surgery femoral bone cavitas medullaris dedicated for SuperPATH approaches
File.The femoral myelocavity file is made to meet the needs of the minimally invasive Posterior approach of hip replacement surgery, while notch is not expanded, fully
It using spatium intermusculare, while can be good at getting out femoral bone cavitas medullaris again, reach the needs of bone-cement type hip replacement.
Description of the drawings
Fig. 1 is the structure diagram of the bone-cement type hip replacement femoral myelocavity file of the utility model preferred embodiment.
Fig. 2 is the top view of Fig. 1.
Fig. 3 is the B enlarged drawings in Fig. 1.
Specific embodiment
It is new below in conjunction with this practicality to make the purpose, technical scheme and advantage of the utility model embodiment clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is the utility model part of the embodiment, instead of all the embodiments.Based on the implementation in the utility model
Example, those of ordinary skill in the art's all other embodiments obtained on the premise of creative work is not made all belong to
In the scope of the utility model protection.
As shown in Figs. 1-3, the present embodiment provides a kind of bone-cement type hip replacement femoral myelocavity file, suitable for warp
The preparation for the bone-cement type hip replacement surgery femoral bone cavitas medullaris that the minimally invasive approaches of SuperPATH are completed.
See Fig. 1 and 3, which includes a file body 1, which equably lays on the front and back
There is the blade 2 of multiple drops, multiple small sawtooth 3 are equably laid on the both sides vertical direction of the file body 1, the file body
1 end is embedded with a file interface that connection is matched with the dedicated Myelocavity file connecting rod of SuperPATH approaches.
Wherein, Fig. 2 is seen, which includes an interface body 4, and one is offered in the interface body 4 for being embedded the marrow
Chamber files the groove 5 of connecting rod, and the groove 5 is oval, and the end of the interface body 4 is connected with a stent 6.
By being different from the design of common Myelocavity file, the Myelocavity file is allow to connect the minimally invasive approach hip joints of SuperPATH
The Myelocavity file connecting rod of replacement operation allows doctor to complete bone-cement type femur in the range of SuperPATH approaches appear
The femoral bone cavitas medullaris of handle prepares, so as to complete bone-cement type hip replacement surgery.
Although the foregoing describe specific embodiment of the present utility model, it will be appreciated by those of skill in the art that
These are merely examples, and the scope of protection of the utility model is defined by the appended claims.Those skilled in the art
Member can make these embodiments numerous variations or repair on the premise of the principle and essence without departing substantially from the utility model
Change, but these change and modification each fall within the scope of protection of the utility model.
