Description
Technical Field
The utility model belongs to the technical field of medical instrument, particularly, the utility model relates to a take orthopedics sacculus and orthopedics sacculus equipment of sawtooth cable.
Background
Fractures are classified according to the shape of the fracture line: fracture, infraperiosteal fracture, brachial fracture, lacerated fracture, transverse fracture, oblique fracture, spiral fracture, comminuted fracture (fracture pieces broken into three or more pieces called comminuted fracture), impaction fracture, depressed fracture, and compression fracture.
Compression fractures are one type of bone fracture. In the compressive fracture, the vertebral column vertebral body compression fracture is the most common fracture of human body, especially is commonly seen in the old people with osteoporosis. The domestic epidemiological research in 2017 shows that the prevalence rate of vertebral compression fracture of Beijing postmenopausal women increases with age, the prevalence rate is 13.4% at 50-59 years and is as high as 58.1% above 80 years.
The number of new vertebral body compression fracture cases is 127 ten thousand for people over 50 years old in 2015 in China; it is expected that 149 million cases will be reached by 2020; in 2050, 300 ten thousand cases can be obtained. For the compression fracture of vertebral body with unsatisfactory conservative treatment, minimally invasive vertebral body strengthening operation, especially kyphoplasty by using a balloon is the most commonly used effective treatment method.
When compression fracture occurs, the fracture end is often hardened and scar granulation tissue is filled in a sub-fresh or old fractured bone with the fracture time of more than 2-3 weeks, and then healing is delayed or even not healed. For delayed union or nonunion of a fracture, the most important treatment is to remove hardened scars and stale tissue at the fracture end, i.e., to freshen the fracture end, before the fresh bone tissue has the condition and space to grow well.
When the balloon kyphoplasty is clinically carried out, the fracture end cannot be directly exposed due to minimally invasive percutaneous surgery, and the conventional balloons have smooth surfaces and cannot directly remove hardened scar tissues; the special curet and other instruments have small action range, insufficient torsion force and risks of instrument fracture and the like, and the clinical application is few and the risks are uncontrollable.
Therefore, for the very common delayed or nonunion of vertebral compression fracture, an effective means for the fracture end freshness treatment is not available at present to achieve a good treatment effect, and the perfusion of bone cement cannot provide a basis for the regeneration of bone tissues completely. Therefore, when fracture occurs in the bone bodies of vertebrae, thighbones, shinbones, humerus and the like which can be subjected to interventional therapy by adopting the orthopedic balloon, old tissues need to be debrided so as to provide a foundation for bone repair of the vertebral bodies and open a road.

Example 3
As shown in fig. 7 and 12, two saw-tooth cables 7 are provided, the two saw-tooth cables 7 are spirally wound on the balloon base body 2, the rotating directions are opposite, the rotation starting points are symmetrically arranged by taking the axis of the balloon base body 2 as the symmetric center, the saw-tooth cables 7 and the balloon base body 2 are of an integrated structure and are made of the same material, namely, the saw-tooth cables 7 and the balloon base body 2 are integrally formed, diamond powder is laid in a mold or a tool cavity when the balloon base body 2 is subjected to thermoplastic forming or subsequent processing, and the diamond powder is embedded on the surface of the saw-tooth cables 7. Sacculus base member 2 links to each other with conveyer pipe 3, and conveyer pipe 3 links to each other with supersonic generator, and when the sclerosis scar of cutting the internal bone and not fresh tissue, supersonic generator drove 3 axial oscillations of conveyer pipe to drive sacculus base member 2 vibration, 7 vibration cutting sclerosis scars of sawtooth cable on sacculus base member 2 surface and not fresh tissue can realize the freshing of fracture end.
When implementing, conveyer pipe 3 also can link to each other with motor 61 through the shaft coupling, when sclerosis scar and the not fresh tissue in the cutting bone body, motor 61 drives conveyer pipe 3 and rotates to drive sacculus base member 2 and rotate, 7 rotatory cutting sclerosis scars of sawtooth cable on 2 surfaces of sacculus base member and not fresh tissue can realize the freshness of fracture end, because the precession of sawtooth cable 7 is opposite this moment, can further improve the cutting dynamics to sclerosis scar and not fresh tissue for the sawtooth cable 7 of the same precession.
Example 4
As shown in fig. 3 and 7, a plurality of sawtooth cables 7 are uniformly arranged on the balloon base body 2 in an annular shape, the sawtooth cables 7 are assembled in a mold as a framework when the balloon base body 2 is subjected to thermoplastic molding, the sawtooth cables 7 and the balloon base body 2 are integrated after the balloon base body 2 is molded and protrude out of the outer surface of the balloon base body 2, the balloon base body 2 is made of a thermoplastic elastomer material, and the sawtooth cables 7 are made of an engineering plastic material. Sacculus base member 2 links to each other with conveyer pipe 3, and conveyer pipe 3 links to each other with supersonic generator, and when the sclerosis scar of cutting the internal bone and not fresh tissue, supersonic generator drove 3 radial vibrations of conveyer pipe to drive sacculus base member 2 along conveyer pipe 3's radial vibration, 7 vibrations of sawtooth cable on the sacculus base member 2 cut sclerosis scar and not fresh tissue, can realize the freshness of fracture end.
Example 5
As shown in fig. 7 and 13, a plurality of sawtooth cables 7 are uniformly arranged on the balloon base body 2 in an annular shape, the sawtooth cables 7 are assembled in a mold as a framework when the balloon base body 2 is subjected to thermoplastic molding, the sawtooth cables 7 and the balloon base body 2 are integrated after the balloon base body 2 is molded and protrude out of the outer surface of the balloon base body 2, the balloon base body 2 is made of a thermoplastic elastomer material, and the sawtooth cables 7 are made of an engineering plastic material. Sacculus base member 2 links to each other with conveyer pipe 3, and conveyer pipe 3 links to each other with cylinder/pneumatic cylinder, and when sclerosis scar and not fresh tissue in the cutting bone body, cylinder/pneumatic cylinder drive 3 axial reciprocating motion of conveyer pipe to drive sacculus base member 2 along conveyer pipe 3's axial motion, 7 reciprocal cutting sclerosis scars of sawtooth cable on the sacculus base member 2 and not fresh tissue can realize the freshness of fracture end.
