Description
Technical field
The invention belongs to field of medical device, and in particular to a kind of orthopaedics Minimally Invasive Surgery bellows extension fixture.
Background technology
Orthopaedics is also known as orthopaedic srugery, is the specialty or subject of medical science, specializes in dissecting, giving birth to for skeletal musculature
Reason and pathology, keep and develop the normal morphology and function of this system with medicine, operation and physical method, and treat this
One system it is sick and wounded.With the development of science and technology and progressive, orthopaedics has very big progress in terms of diagnosis, treatment.It is " micro-
This concept of wound " has been deep into the various fields of surgical operation, and it, which has, recovers fast, the characteristics of few intercurrent disease, alleviates patient
Pain.
At present, orthopaedics Minimally Invasive Surgery is that Kirschner wire is first inserted into certain position under monitoring, then by sky of different sizes
Heart sleeve increases step by step, until intervention passage reaches suitable size.However, the design defect due to sleeve tube wall in itself, still
There is damage reason location Kirschner wire peripheral vessels, the risk of nerve.
The content of the invention
Regarding to the issue above and not enough, the present invention provides a kind of orthopaedics Minimally Invasive Surgery bellows extension fixture, from inside expansion
Passage is opened up, blood vessel and nerve so as to prevent surrounding etc. is damaged, and improves the efficiency of the practice of orthopaedics Minimally Invasive Surgery, and avoid
The generation of postoperative complication.
To solve the above problems, being adopted the technical scheme that：
A kind of orthopaedics Minimally Invasive Surgery bellows extension fixture, including inner sleeve and outer tube, the inner end of the inner sleeve stretch out
The inner end of outer tube, and the inner end of inner sleeve is provided with upper flange platform, the inner end of the outer tube be provided with it is upper
The corresponding lower flange platform of flange platform, is provided with air bag between upper flange platform and lower flange platform, the inner end of the inner sleeve
Passage corresponding with air bag is offered on the wall of side, the inner sleeve is matched with outer tube to be slidably socketed, and in inner sleeve and outside
Sealing ring is provided between sleeve pipe.
It is preferred that, each incline of the upper flange platform and lower flange platform is rounding off.
It is preferred that, the inner sleeve outer end is provided with snap joint, and inner sleeve is connected with physiology salt by snap joint
Water injection mechanism or air pump.
It is preferred that, the sealing ring is multiple tracks, and offers on interior sleeve outer wall sealed groove corresponding with sealing ring,
Sealing ring matching is embedded in sealed groove.
It is preferred that, the section undulate structure of the air bag.
Using above-mentioned technical proposal, acquired beneficial effect is：
Orthopaedics Minimally Invasive Surgery intramedullary expansion opening apparatus of the present invention, from internal extended passage, so as to prevent surrounding blood vessel and
Nerve etc. is damaged, and improves the efficiency of the practice of orthopaedics Minimally Invasive Surgery, and avoid the generation of postoperative complication.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Fig. 2 is the structural representation after of the invention open.
Fig. 3 is the broken section structural representation in Fig. 2.
Sequence number in figure：1 it is inner sleeve, 2 be outer tube, 3 be upper flange platform, 4 be lower flange platform, 5 be air bag, 6 is ventilation
Hole, 7 be sealing ring, 8 be snap joint, 9 be sealed groove.
