Abstract
The invention belongs to the field of medical instruments and relates to a reinforcing device used when a metal nail plate is detached after internal fracture fixation operation union of a patient, in particular to a reinforcing bar for supporting a pore passage of a bone nail. The reinforcing bar for supporting the pore passage of the bone nail comprises a cylindrical bar body used for supporting the pore passage of the bone and a diversion groove is formed in the bar body and is a through hole penetrating through the bar body. The reinforcing bar for supporting the pore passage of the bone nail is used for effectively solving the problems that when the metal bone connecting plate and metal bone connecting nails are detached after internal fracture fixation operation union, the perforated portion of the fracture portion is unstable and the cancellous bones collapse.
Description
Technical field
The invention belongs to medical apparatus and instruments field, relate to a kind of bracing means of fracturing and using when internal fixation operation healing is rear removes metal nail-plate patient, specifically a kind of nail duct bracing reinforcement rod.
Background technology
When carrying out fracture operation, conventionally adopt metallic plate and metallic screw to fracture interior fixing, after union of fracture, need to remove peg and metallic plate, at the position of peg, can leave screw duct quite a lot, these ducts have reduced the bone strength at position, place, particularly through fracture Mian Ding road, have increased local unstability, easily make patient that secondary fracture occurs; Near the spongy bone of joint part, after metallic screw is removed, very easily cause spongy bone to subside, thereby produce even more serious joint problem, when increasing financial burden to patient, also increased patient's misery.At present also do not have clinically suitable apparatus and method to solve the problems referred to above, conventionally cannot process tearing the duct staying after nail open, at the most also can only duct compared with superficial part position, insert a small amount of filling material of bone, this is can not reach clinical requirement far away.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of nail simple in structure, ingenious, rational duct bracing reinforcement rod is provided, this reinforcing rod can effectively solve after patient's union of fracture, because remove metallic plate and peg, at operative site, leave screw duct and cause bone strength to reduce, the problem that even spongy bone subsides.
According to technical scheme provided by the invention: a kind of nail duct bracing reinforcement rod, is characterised in that: comprise that described barred body is provided with guiding gutter for supporting the cylindrical barred body in skeleton duct.
As a further improvement on the present invention, described guiding gutter is to run through the through hole being arranged on barred body.
As a further improvement on the present invention, described guiding gutter, for being arranged at barred body edge, outwards being dehisced and runs through the groove that barred body arranges.
As a further improvement on the present invention, on described barred body periphery, be laid with some protruding ridges, between adjacent two protruding ridges, form guiding gutter.
Nail of the present invention duct bracing reinforcement rod adopts implantable degraded and absorbed biomaterial to make, and is mainly that the main biomaterial adopting is polylactic acid (PLLA), PLGA (PLGA), polylactide copolymer, PLGA, hydroxyapatite (HA) etc.
The present invention compared with prior art, advantage is: when product of the present invention is removed metal bone fracture plate and metal bone nail for fracture operation healing is rear, the unstability that fracture punching position exists even causes the problem that spongy bone subsides and special design exploitation can effectively address the above problem.
Accompanying drawing explanation
Fig. 1 is the structural representation of the first embodiment of the present invention.
Fig. 2 is the structural representation of the second embodiment of the present invention.
Fig. 3 is the structural representation of the third embodiment of the present invention.
The specific embodiment
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in Fig. 1 ~ 3, comprise barred body 1, guiding gutter 2, protruding ridge 3 etc.
As shown in Fig. 1 ~ 3, a kind of nail of the present invention duct bracing reinforcement rod, comprises that described barred body 1 is provided with guiding gutter 2 for supporting the cylindrical barred body 1 in skeleton duct.
Fig. 1 shows the first embodiment of the present invention, and as can be seen from Fig. 1, guiding gutter 2 is one to run through along its length the through hole being arranged in barred body 1.
Fig. 2 shows the second embodiment of the present invention, and as can be seen from Fig. 2, guiding gutter 2, for being arranged at barred body 1 edge, outwards being dehisced and runs through the groove that barred body 1 arranges.
Fig. 3 shows the third embodiment of the present invention, is laid with some protruding ridges 3 on barred body 1 periphery, between adjacent two protruding ridges 3, forms guiding gutter 2.
Product of the present invention in clinical practice in bone surgery, when patient's bone surgery, with classical inner fixing device " metal bone fracture plate and metal bone nail ", fracture site is fixed, after patient's union of fracture, pull down metal bone fracture plate and metal bone nail, according to the length of metal bone nail and diameter, select suitable nail duct bracing reinforcement rod, this product is inserted to metal bone nail and extract in the duct of rear formation.Because adopting, can be made by the biomaterial of human body degraded and absorbed this product (the main biomaterial adopting is polylactic acid (PLLA), PLGA (PLGA), polylactide copolymer, PLGA, hydroxyapatite (HA) etc. at present), be used for supporting duct nontoxic to human body, can be by human body degraded and absorbed.
This product has considered bone physiology, biomechanics and clinical needs and development and Design has effectively been filled up blank both domestic and external.At present, with regard to nationwide, will remove millions of bone screw every year, the perfect and development to Orthopedic Clinical after the industrialization of this product is significant, and also will produce larger economic and social benefit simultaneously.
