Abstract

The utility model relates to a bone plerosis adder, which is tabular and can be extended with several extension segments. The tabular surface is the third surface correspondingly with bone of the human, on the tabular surface, several through holes of the adder are equally or approximately equally distributed, and several groups of counter sunk are around the tabular surface and certain distance is between each group of counter sunk. The adder can be with computer technology for personality design and precise manufacturing for statuses of the patients. The utility model has the advantages of high precision and high design and processing precision. The invention can be used for craniofacial injury plerosis for bone defect after being removed of pathological changes. The bone plerosis adder has incomparable superiority with traditional mode on connection of defect parts and beauty of appearance shapes.

Description

Bone is repaired dribbleware

Technical field

This utility model relates to a kind of implantation dribbleware that bone injury such as cranium jawbone is repaired that is mainly used in.

Technical background

The existing implantation dribbleware that is used to repair bone injuries such as skull, jawbone adopts titanium metal net more, need the concrete condition of elder generation during use according to damage location, determine the size and the shape of required dribbleware, titanium metal net is carried out cutting and on-the-spot processing such as moulding, form required dribbleware.The defective one of this technology is that the intensity of titanium metal net is not high, influences repairing effect; The 2nd, the precision of Site Design and processing is not high, can't form personalized high quality of products.

The utility model content

For overcoming the above-mentioned defective of prior art, this utility model provides a kind of bone to repair dribbleware, and the intensity height of this dribbleware can also adopt high-precision design and processing mode to make the product quality height simultaneously.

This utility model realizes that the technical scheme of above-mentioned purpose is: a kind of bone is repaired dribbleware, is tabular, and the plate face is curved-surface shape, and is distributed with some through holes that penetrate dribbleware, and the peripheral position of plate face is distributed with some groups of nail holes.

The beneficial effects of the utility model are: owing to adopted platy structure, under material and all identical situation of thickness, its intensity is apparently higher than existing cancellated dribbleware; Simultaneously also because this dribbleware can adopt computer image technology, Computer-aided Design Technology and precision casting technology, concrete condition at the patient is carried out personalized design and making, form design and all very high product of machining accuracy, can adapt to needs of patients well, aspect the aesthetic property of the applying of defect and face shaping, the incomparable advantage of traditional approach being arranged, can be used for the damaged multiple uses such as reparation of cranium maxillofacial trauma or pathological changes excision back bone.

Description of drawings

Fig. 1 is a planar structure sketch map of the present utility model.

The specific embodiment

Referring to Fig. 1, the bone that this utility model provides is repaired dribbleware and is tabular, and its plate face 1 is curved-surface shape (can be three-dimension curved surface usually), and is distributed with some through holes 3 that penetrate dribbleware, and the peripheral position of plate face 1 is distributed with some groups of nail holes 4.

Described plate face edge 2 can adopt level and smooth curve-like (curve is adopted at the clinodactyly position, can have the straight line portion tangent with curved portion) usually, in order to avoid damage is caused to body in the angle on the edge.

Described plate face 1 can be plane, can be tabular (the only bending on single direction of plate face of single-curved surface, promptly have at least the cross section of a direction linearly all the time), can also be that tabular (the plate face is crooked on a plurality of directions for many curved surfaces, the cross section of any direction is all uneven linearly), to adapt to the reparation of different parts.In the practice, these curve forms can carry out the data acquisition and the design of human body bone nature curved-surface structure by computer image technology, form and the identical shape of human body bone nature curved surface.

Described plate face 1 often can adopt spherical crown shape or approximate spherical crown shape, to adapt to the reparation of skull.

Described through hole 3 usually evenly or approximate being evenly distributed on the whole plate face 1 (decide according to the dribbleware shape, can only distribute according to approximate uniform mode) at irregularly shaped lower through-hole.This through hole set-up mode helps the ankylose of inside and outside tissue, and is convenient to carry out possible drain processing.

The pore diameter range of described through hole 3 can be 3mm to 8mm usually, preferred 4-5mm, for example 3mm, 4mm, 4.5mm, 5mm, 6mm or 8mm.Average pitch-row between the adjacent through-holes should require to adapt with the organize ankylose and the drain of repairing the position, usually can be 4mm-20mm, preferred 7-12mm, for example 4mm, 5.5mm, 6mm, 7mm, 8.5mm, 10mm, 12mm, 15mm or 20mm, number of openings is decided according to the area of dribbleware.

Described nail hole 4 can be used for dribbleware in patient's fixed installation on one's body.Usually adopt the titanium nail to pass nail hole 4, be connected on the skeleton.The aperture in described nail hole 4 should adapt with supporting titanium nail, and the distribution mode in nail hole should adapt with the shape of dribbleware, with the reliability that guarantees that dribbleware installs and fixes.

The quantity in described each group nail hole can be 3 usually, also can be 2 or 1 etc.Each group is followed closely the segment distance of can being separated by between hole.

Firm for guaranteeing that dribbleware is installed, should on dribbleware, the nail hole all should be set extended each end usually, and the nail hole also can be set at the middle part of longer edges.

Described nail hole 4 can be provided with chamfering at the dribbleware outer surface, so that match with ailhead.

The inside and outside surface of this dribbleware can be slick usually, but also can be coarse in case of necessity, and perhaps one-sided smooth, one side are coarse, and concrete mode should and be decided according to the needs of repairing.

For adapting with the skeleton that will repair, the planar development shape of this dribbleware is irregular shape often, for example often need extend several extensions 5.

This dribbleware thickness everywhere usually should be identical, and thickness range can be 0.4mm to 2.5mm, common 1.0mm-2.0mm, for example 0.4mm, 0.8mm, 1.0mm, 1.2mm, 1.35mm, 1.5mm, 1.8mm, 2.0mm or 2.5mm.The selection of thickness can be determined according to the concrete condition at reparation position.

This dribbleware can adopt the Titanium that meets the medical science standard to do raw material usually, also can adopt some special rustless steel or macromolecular material, can adopt the mode machine-shaping of precision digital casting.
