Technical field
The invention belongs to technical field of medical instruments, the micro- contact steel of bulb joint in specifically a kind of medical shackle-type
Plate bolt system.
Background technology
The treatment method of the most common Clinical practice of fracture is steel plate screw Internal fixation technology, traditional steel plate screw system
System be by steel plate by fixed to the screw among sclerotin and squeezed tight on fixed bone, can be destroyed fracture site and
The blood fortune at position is closed on, so as to have influence on the agglutination of sclerotin, delayed union easily occurs, the complication such as is not connected to.And
Excessively strong interior fixation can form so-called stress-shielding effect, and the normal stress conduction for making fracture local does not pass through bone
Matter, conducted on the contrary by steel plate screw, local osteoporosis can be caused, further influence local fixing intensity, increase bone again
The complication such as folding, steel plate screw fracture.Therefore, how fracture site can either be fixed, local blood supply damage can be reduced again, subtracted
Few stress-shielding effect, it is allowed to which material such as blood vessel, mineralized bone matrix, the Gegenbaur's cell etc. for having positive role to fracture site are grown into
Between fixture and sclerotin, the reconstruction process of bone can be improved, reduce osteoporosis, fragmentation of internal fixation objects, delayed fracture
The generation of the complication such as healing.
The content of the invention
Conventional steel plates excessive compression is fixed on local sclerotin existing for prior art the invention aims to solving,
It is caused to destroy local blood supply and stress-shielding effect and trigger osteoporosis, steel plate screw fracture, bone delay in healing etc. concurrent
Disease, and the micro- contact steel plate screw system of bulb joint in a kind of medical shackle-type provided.The system can considerably reduce steel
Plate bolt and by the contact area between fixed sclerotin, it is strong outside periosteum to connect as one, so as to provide blood vessel, Gegenbaur's cell

Embodiment
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description.
To make the object, technical solutions and advantages of the present invention clearer, the technology below in conjunction with accompanying drawing to the present invention
Scheme is clearly and completely described, it is clear that and described embodiment is part of the embodiment of the present invention, rather than whole
Embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art are obtained under the premise of creative work is not made
The every other embodiment obtained, belongs to the scope of protection of the invention.
With reference to shown in figure 1-7, the embodiment is the micro- contact steel plate screw system of bulb joint in a kind of medical shackle-type, bag
Include：
Bulb Universal screw nail 10, bulb Universal screw nail 10 include head 11 and body portion 12, and head 11 is spherical, the band of body portion 12
There is external screw thread to be screwed into sclerotin, bulb diameter is more than its body portion diameter.
Ball impression steel plate 20, ball impression steel plate middle part carry spherical groove 21, can matched with the head 11 of bulb Universal screw nail 10,
Its diameter of spherical groove 21 is less than the diameter of head 11 of bulb Universal screw nail；
Bulb Universal screw nail 10 and ball impression steel plate 20 are used for fix bone.
Fixture block 30, including two, respectively fixture block 31 and fixture block 32；
Fixture block 31 includes the upper, middle and lower being connected as a single entity, and top is square and is provided with screwed hole 311, and middle part is set
There is U-type groove 312, lower inside surface is arcwall face 313,
The top of fixture block 32 is square and is provided with unthreaded hole 321, and middle part is provided with U-type groove 322, and lower inside surface is arcwall face
323；
U-type groove opening in the middle part of two fixture blocks is mounted opposite, for two fixture block installations space appearance that it is formed after in place
Receive ball impression steel plate, the arcwall face that two fixture block bottoms are mounted opposite, for two fixture blocks installations it is in place after its space formed hold
Receive the bulb bottom of bulb Universal screw nail 10.Moreover, after fixture block 30 and ball impression steel plate 20 connect, the spherical groove of ball impression steel plate 20
21 and the arcwall face of fixture block lower inside surface form continuous spherical radian face.
Pinning 40 is connected, the partial-length in connection pinning body portion carries the internal thread in external screw thread, with fixture block upper hole
With locking, the body portion is penetrated and is locked in the hole on two fixture block top, and two fixture blocks are connected for locking.To avoid two folders
Mismatch caused by the upper hole internal thread of block is discontinuous, so the partial-length in connection pinning body portion carries external screw thread.
Fixture block 30 and connection pinning 40 be used for fix bulb Universal screw nail 10 and ball impression steel plate 20, finally constitute one it is whole
Body.
When in use, first the body portion 12 of bulb Universal screw nail 10 is screwed into by fix bone in any direction, then will
The spherical groove 21 of ball impression steel plate 20 is covered in bulb Universal screw nail head, fixture block 30 and connection pinning 40 by ball impression steel plate 20 with
Bulb Universal screw nail 10, which is connected, to be integrated, and so after installation composition, ball impression steel plate 20 and gap between fix bone be present.
In order that with reliably, fixture block 31 and fixture block 32 are suggested pairing processing, used.Standard component can be selected in connection pinning 40.
, can standby more set structures of the present invention because surgery situation is changeable.The material and size of each part can be according to actual conditions and operation
Need to determine.
In the present embodiment, in order that ball impression steel plate 20 and bulb Universal screw nail 10 are connected and be integrated, two are used
Fixture block splices, make it is in place after the central space that is formed accommodate ball impression steel plate, while fixture block by ball impression steel plate with by fix bone every
Open form is into gap, the bulb bottom of its space bulb Universal screw nail formed after the installation of fixture block lower inside surface is in place, so
Connection pinning is screwed into the tapped hole on fixture block top afterwards, fixture block is connected into locking fixes.
Specifically, connection pinning body portion screw thread of the invention can be mutually chimeric with the internal thread in fixture block upper hole, from
And it is connected as a single entity by ball impression steel plate, bulb Universal screw nail and by fix bone.So caused by beneficial outcomes be：Use fixture block
Ball impression steel plate and bulb Universal screw nail can be fastened on one with connection pinning, made between being left between ball impression steel plate and bone
Gap, so as to provide the gap that blood vessel, Gegenbaur's cell and other regenerating tissues are grown between steel plate and sclerotin, be advantageous to accelerate normally
Healing process.
Finally it should be noted that：The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although
The present invention is described in detail with reference to the foregoing embodiments, it will be understood by those within the art that：It still may be used
