Abstract
The invention discloses a patella external fixing support, which comprises a fixing support main body and a plurality of metal bone needles, wherein the fixing support main body is a partially-hollow spherical housing gradually shrunk from the bottom surface to the top surface and is provided with a spherical center; a plurality of threaded holes are evenly distributed around the spherical center on the circumferential surface of the fixing support main body; the metal bone needles can penetrate through the threaded holes for bolt fixing. The patella external fixing support provided by the invention can externally fix all kinds of patellar fracture in a comprehensive way, has excellent stability, and avoids all sorts of defects of internal fixing.
Description
Technical field
The present invention relates to medical instruments field, relate in particular to a kind of patella external fixer.
Background technology
Fixing for Patella fracture, most of in the market what adopt is all the fixed form of internal fixation device, as: tension band, have internal fixation plate and shape-remembering alloy claw, hollow screw to add the series such as wire binding.But interior fixed product has its unavoidable defect: do that second operation is fixing in taking out, operation need to cut body and cause secondary injury, cutting operation that patient is larger to place internal fixation device also can to strengthen the chance etc. of bringing infection.Therefore in the last few years, in treatment Patella fracture, less use fixed product outside some both at home and abroad, but these outer fixed product are all not mature enough, such as around the eighties, there are some once to occur momently as outer fixed product such as patella fixator, solid kneecap devices, but mostly, because of the defect of stability aspect and operability aspect, eliminated by market at leisure.
In the last few years, along with the advantages such as reliable and draw point drain are not cut, fixed in unique Wicresoft that outer fixed product has, also slowly became clinically the common recognition of operative doctor in operation.Therefore, designing a kind of novel patella external fixer, is those skilled in the art's problem demanding prompt solutions.
Summary of the invention
The object of the present invention is to provide a kind of patella external fixer, can fix in all directions various types of Patella fracturies in outside, stability is good, and the fixing all kinds of defects that exist in having avoided.
The technical scheme that realizes above-mentioned purpose is:
A kind of patella external fixer, comprises fixed mount body and some metal bone needles, wherein:
Described fixed mount body is the part hollow sphere hull shape shape successively tightening to end face from bottom surface, is provided with a centre of sphere;
On the periphery of described fixed mount body, be evenly equipped with some screwed holes around the described centre of sphere;
Described metal bone needle can be threaded with described screwed hole.
In above-mentioned patella external fixer, described all screwed holes are divided into 2～4 layers of arrangement from bottom to top, the central axis of each layer of screwed hole points on the axis of described fixed mount body certain a bit, and the central axis of each layer of screwed hole is all different from the angle of described fixed mount body bottom surface.
In above-mentioned patella external fixer, described metal bone needle comprises needle point, the screw thread at middle part and the installing handle of afterbody at top, and specification, the size of described screw thread are all consistent with described screwed hole.
In above-mentioned patella external fixer, described all screwed holes are divided into 3 layers of arrangement from bottom to top.
In above-mentioned patella external fixer, described metal bone needle is at least 3.
In above-mentioned patella external fixer, the diameter of described screwed hole is 0.2cm～1.0cm.
In above-mentioned patella external fixer, the end face of described fixed mount body is as the circular form of observing use.
The invention has the beneficial effects as follows: the present invention adopts that densely covered locking screw thread hole is multi-direction, the fixed form of multi-angle, can be by metal bone needle in different angles and different positions, fix in all directions various types of Patella fracturies, fixing the same stablizing effect in having played, but avoid again interior fixing secondary to take out operation and compared with major operation wound simultaneously, be easy to the defect infecting, the present invention is simple in structure, easy to use, greatly lower the difficulty of operation technique, ensured the optimum efficiency of operation.
Brief description of the drawings
Fig. 1 is the structural representation of patella external fixer of the present invention;
Fig. 2 is the structural representation of metal bone needle in the present invention;
Fig. 3 is the structural representation of fixed mount body of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
Refer to Fig. 1 and Fig. 2, patella external fixer of the present invention, comprises fixed mount body 1 and some metal bone needles 2, wherein:
Fixed mount body 1 is the hollow ball shell shape of part, successively tightens to end face from bottom surface, that is: the bottom surface of fixed mount body 1 and end face are circle, and each the coaxial diameter of a circle on fixed mount body 1 reduces gradually from top to bottom; The end face of fixed mount body 1 is as the circular form 11 of observing use;
The fixed mount body 1 of hollow ball shell shape is provided with a centre of sphere, on the periphery of fixed mount body 1, be evenly equipped with some screwed holes 12 around the centre of sphere, these screwed holes 12 are divided into 2～4 layers of arrangement (preferably 3 layers) from bottom to top, the central axis of each screwed hole 12 of each layer all points on the axis of fixed mount body 1 certain a bit, taking 3 layers as example, what each layer of screwed hole 12 pointed to can be that same point can be also 3 different points, and the central axis of each layer of screwed hole 12 is all different from the angle of fixed mount body 1 bottom surface, screwed hole 12 is multi-direction, multi-angle, can make metal bone needle 2 be arranged on different angles and different positions, ensure to fix from each orientation various types of Patella fracturies,
Metal bone needle 2 is supporting with screwed hole 12, and metal bone needle 2 is divided into needle point 21, the screw thread 22 at middle part and the installing handle 23 of afterbody at top, and specification, the size of screw thread 22 are all consistent with screwed hole 12; Metal bone needle 2 is at least 3; Refer to Fig. 3, in the present embodiment, the diameter d of screwed hole 12 is 0.2cm～1.0cm (recommendation is 0.3cm);
To sum up, according to the needs of actual patella fracture, use several metal bone needles 2 to select different positions to be screwed into the screwed hole 12 of correspondence position, and wear surely and fix with Patella fracture piece, and can observe from circular form 11, realize outer fixing.
Above embodiment is used for illustrative purposes only, but not limitation of the present invention, person skilled in the relevant technique, without departing from the spirit and scope of the present invention, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present invention, should be limited by each claim.
