Description
Technical field
This utility model belongs to technical field of medical instruments, and particularly, this utility model relates to a kind of fractures marrow inside and outside dual and stablizes holder.
Background technology
Fracture is that the seriality of bone structure ruptures wholly or in part.The main cause that fracture occurs mainly contains three kinds of situations: 1) direct violence: violence directly acts on a certain position of skeleton and causes this position fracture, often accompanies soft tissue injury in various degree.As wheel clashes into shank, there is fracture of shafts of tibia and fibula in shock place.2) indirect violence: by longitudinally conduction, leverage or twisting action make to fracture at a distance during indirect violence effect, as fall from eminence foot land time, trunk because gravity relation is sharply to pre-buckling, the vertebral body generation compressibility of breast lumbar spine intersection or bursting fracture.3) accumulation property strain: for a long time, repeatedly, slight direct or indirect damage can cause limbs a certain specific part fracture, also known as fatigue fracture, easily causes 1/3 shaft fracture under second and third metatarsal and fibula as walked at a distance.
The treatment of fracture generally adopts replacement and fixation, and after the reduction of the fracture, because of instability, easy generation is shifted again, diverse ways therefore will be adopted to be fixed in satisfied position, make it heal gradually.Conventional fixing means has: plintlet, plaster bandage, exterior fixation bracket, traction braking are fixing, and these fixing meanss claim extenal fixation.If fixing by surgical incision steel plate, draw point, intramedullary needle, screw etc., then claim internal fixtion.But for the fracture of elongate bone (such as fibula), when fixing, due to the rotation of internal fixation nail, often fixed effect is bad, and key thin, fix even if application intramedullary pin also cannot carry out lock hole.Therefore, a kind of fracture fixing apparatus that can overcome above-mentioned shortcoming of research design is needed badly.
Utility model content
The purpose of this utility model is, provide a kind of fractures marrow inside and outside dual to stablize holder, this holder does not need intramedullary pin internal lock hole to fix, can anti-rotation, and good fixing effect, can prevent the bad secondary damage to fracture portions of fixed effect.
For achieving the above object, this utility model have employed following technical scheme:
A kind of fractures marrow inside and outside dual stablizes holder, described holder comprises internal fixation nail 1 and fixing head 2, nail bar 11 upper end of described internal fixation nail 1 arranges some breach 12, the wedge shape lower end of nail bar 11 arranges groove 13, this groove 13 extends along nail bar 11 to upper end, and the degree of depth of groove along nail bar 11 by lower end to upper end in gradually shoaling;

In this utility model, groove 13, for being close to Kirschner wire, being convenient to internal fixation nail 1 and being entered in bone, and accurate positioning, internal fixation nail can not be made when entering in bone to depart from default duct.
Preferably, described nail bar 11 is flat column or semi-cylindrical.Those skilled in the art can also select other shapes as required.
Preferably, the quantity of described breach 12 is two or three.Those skilled in the art can also select other quantity as required, such as five etc.This utility model arranges multiple breach, is convenient to a part of blocking nail bar in art according to the needs of nail pole length from indentation, there, time saving and energy saving.
Preferably, the quantity in described fixing pressurization hole 22 is four.Those skilled in the art can also select other quantity as required, such as six etc.
Preferably, described pressurization fixing hole 22 is diplopore, and its inboard aperture 221, for fixing, established in its apertura lateralis 222 and added pressure slope 223.
In this utility model, fixing pressurization hole is set to multiple, is convenient to select as required in art employing one the fixing pressurization hole plate that is strained and fixed still to select multiple fixing pressurization hole to be strained and fixed plate.
Preferably, adding pressure slope 223 described in apertura lateralis centrage is 45-60 ° of angle.
Preferably, described fixing head 2 is strip.Those skilled in the art can also select other shapes as required.Such as T-shaped plate.
Preferably, the making material of described holder is titanium alloy.Those skilled in the art can also select other to make material as required.
Groove in this utility model be arranged on tapered end with on the opposite flank of lozenges.
In this utility model, internal fixation nail is and soft and hard, during use, can carry out deformation, thus be better fixed in bone with internal structure of bone.
Fixing head in this utility model can be close on the bone surface of fracture portions, and fixing head can design different shapes according to fracture portions.
Using method of the present utility model: bone 3 breaks as two parts along fracture line 4, fracture end and base bone, first internal fixation nail 1 be screwed into fracture end and pass fracture line 4 reasonable length, the nail bar 11 of breach 12 part is exposed at the outside of bone 3, then the hanging hole 21 of fixing head 2 is hung in breach, fixing head 2 is being extended along bone 3 to fracture portions, and cover fracture portions, screw is adopted to be screwed in the apertura lateralis 222 of pressurization fixing hole 22, in this fixation procedure, fixing head 2 is subject to pull strength effect, tension hanging hole and breach, herein after tension, internal fixation nail can not rotate, can better be fixed fracture portions.After straining hanging hole and breach, more some screws are adopted to be fixed on bone by fixing head.
This utility model is used for Minimally Invasive Surgery, is applicable to the fixing of elongate bone fracture, such as fibula, tibia, clavicle, breastbone etc.
Compared with prior art, its advantage is this utility model:
This utility model arranges the breach that can tangle fixing head on internal fixation nail, and this breach can closely cooperate with the hanging hole on fixing head, thus prevents the rotation of internal fixation nail.In addition, this utility model arranges the pressurization fixing hole of diplopore on fixing head, and can better be strained and fixed plate, plays the fixing of tension band action effect.
