Description
Technical field
The present invention relates to medical instruments fields, and in particular to a kind of multi-shaft locking synthetism panel assembly.
Background technique
Micro wound coaptation plate osteopathy is a kind of modern Fracture internal fixaiion technology, it uses closed fracture resetting technique, is used in combination
Plate fixation without pressurization maintains fracture reduction, so that surgical exposure and soft tissue extent of exfoliation have reached minimum, subtracts
Lack the blood supply destruction to tissues such as skin, periosteum, sclerites, can be improved union rate, and reduces such as infection or bone
Roll over the incidence of the complication such as disunion.Lock hole and screw on existing bone plate are cooperated by way of screw thread, are made
Used time screw slightly skew is not just able to cooperate with lock hole, and degree easy to use is poor.
Summary of the invention
The object of the present invention is to provide a kind of multi-shaft locking synthetism panel assemblies, in the case where guaranteeing bonding strength, doctor
Proper angle can be selected to lock fracture portions according to patients with fractures's situation.
To achieve the above object, the technical scheme adopted by the invention is that: including plate body, plate body is equipped with lock hole, lock
The inner wall for determining hole is equipped at least two column teeth.
Preferably, the lock hole is in a circular table shape.
Preferably, each column tooth is arranged along the extending direction sequence of the center line of lock hole.
Preferably, be staggered non-cross overlapping between every two column tooth.
Preferably, the shape of the tooth is the rectangular pyramid or truncated rectangular pyramids that bottom surface is curved surface diamond shape, and the rectangular pyramid or four
Four sides of terrace with edge are identical.
Preferably, the shape of the tooth is the triangular pyramid or triangular platform that bottom surface is curved surface triangle, and the triangular pyramid or
Triangular platform is split to form for curved surface diamond shape, the identical rectangular pyramid in four sides or truncated rectangular pyramids along its plane of symmetry by bottom surface.
Preferably, the angle that the angle a that the cross section in hole is divided equally can be locked on the bottom surface of the tooth is 6-18 °.
Preferably, the angle that the angle a that the cross section in hole is divided equally can be locked on the bottom surface of the tooth is 10-14 °.
Preferably, it is in symmetrical structure that the inner wall of the lock hole, which is equipped with four column, six column or the six above even column teeth of column, tooth,
Structure is identical between two often opposite column teeth.
Preferably, plate body includes integrally formed bone plate one and bone plate two, the bone plate one and synthetism
The shape that plate is two is adapted with skeleton shape.
After adopting the above technical scheme, the present invention has the positive effect that:
(1) lock hole on a kind of multi-shaft locking synthetism panel assembly of the invention is not spirally connected by screw thread instead of with screw,
The inner wall of lock hole is equipped with even column tooth, and the shape of tooth is in rectangular pyramid or truncated rectangular pyramids or triangular pyramid or triangular platform, on screw
Screw thread and tooth are staggeredly locked, even if can also assemble well with lock hole in the case where screw skew, in actual use process
In, doctor can select proper angle to lock fracture portions according to patients with fractures's situation, greatly improve the work effect of doctor
Rate；
(2) angle that the angle a that the cross section in hole is divided equally can be locked on the bottom surface of tooth is 6-18 °, this angle design is guaranteeing spiral shell
In the case that nail cooperates with lock hole, reduces the resistance of screw receiving, reach locking using the smallest power in use
Screw purpose；
(3) lock hole in the present invention is in a circular table shape, and with gradually screwing for screw, the diameter of lock hole is gradually reduced, more just
In the cooperation of screw and lock hole, further help has been screwed to inclined screw.

Specific embodiment
Invention is further described in detail with reference to the accompanying drawings and detailed description.
Embodiment 1
As shown in Figure 1-3, be a kind of multi-shaft locking synthetism panel assembly of the invention, including plate body 1, this plate body 1 include one at
The bone plate of type one 11 and bone plate two 12, bone plate one 11 and bone plate two 12 shapes with skeleton shape
Shape is adapted.
It is equipped at least one lock hole 2 on bone plate one 11 and bone plate two 12, lock hole 2 is in a circular table shape.One
In use, the big one side in the cross section of screw from lock hole 2 screws in kind multi-shaft locking synthetism panel assembly, lock hole 2
Cross section it is small compared to cross section it is big while closer to human body.The inner wall of lock hole 2 is equipped at least two column teeth 3, often
Column tooth 3 is arranged along the extending direction sequence of the center line of lock hole 2, and be staggered non-cross overlapping between adjacent two column tooth 3,
It is staggeredly locked convenient for the screw thread on screw with tooth 3.Tooth 3 is in symmetrical structure, and structure is identical between two often opposite column teeth 3.
The shape of tooth 3 is tetrapyamid shape, is also possible to quadrangular frustum pyramid shaped, and the bottom surface of the rectangular pyramid or truncated rectangular pyramids is curved surface water chestnut
Shape, four sides are identical, and the inner wall of bottom surface fitting lock hole 2, can be locked what the cross section in hole 2 was divided equally on the bottom surface of tooth 3
The degree of angle a is 6-18 °, it is preferred that the angle of a is 10-14 °.Such shape of tooth 3 designs, and is guaranteeing screw and lock hole 2
In the case where cooperation, reduces the resistance of screw receiving, achieve the purpose that lock-screw using the smallest power in use.
The one side of plate body 1 being bonded with human body is equipped with arc groove, makes a kind of multi-shaft locking synthetism panel assembly and human body bone
Between bone will not completely note it is attached, promote blood circulation, make fracture site restore faster.
In the present embodiment, the inner wall of lock hole 2 is equipped with four column teeth 3, and tooth 3 is in symmetrical structure, the knot of two opposite column teeth 3
Structure is identical.It is appreciated that the columns of tooth 3 can also be two column, six column or the six above even columns of column, it can reach identical with four column
Use purpose.
Embodiment 2
As illustrated in figures 4-5, in the present embodiment, the difference from embodiment 1 is that, the shape of tooth 3 is different.The shape of tooth 3 is bottom
Face is the triangular pyramid or triangular platform of curved surface triangle, and the bottom surface is bonded the inner wall of lock hole 2, the triangular pyramid or triangular platform
Be that curved surface diamond shape, the identical rectangular pyramid in four sides or truncated rectangular pyramids are split to form along its plane of symmetry by bottom surface, two triangular pyramids or
Triangular platform can be spliced into rectangular pyramid or truncated rectangular pyramids in embodiment 1.
When in use, plate body 1 is bonded at human fracture a kind of multi-shaft locking synthetism panel assembly of the invention, screw difference
Lock hole 2 from different location screws in, and in screwing operations, is not required to the angle of adjusting screw, also can guarantee screw and locking
The perfect cooperation in hole 2 alleviates the use burden of doctor.
It will be apparent to those skilled in the art that can make various other according to the above description of the technical scheme and ideas
It is corresponding to change and deformation, and all these change and deformation all should belong to the present invention claims protection scope it
It is interior.
