Description
Technical field
The invention belongs to technical field of medical equipment, and in particular to a kind of minimally invasive tunnel dilator of gasbag-type.
Background technology
Orthopaedics Minimally Invasive Surgery becomes increasingly popular, and Minimally Invasive Surgery, which has, recovers fast, the characteristics of few intercurrent disease, alleviates patient's pain
Hardship, is also the trend of later orthopaedics development.
Current minimally invasive passage is by the way that similar to " Russian Dolls ", one piece of Kirschner wire is inserted into institute under fluoroscopy first
Position is needed, then expands the different cannulated sleeve of diameter step by step, until reaching required size.But, due to sleeve tube wall
The thickness of itself, therefore there are still the vital tissues such as blood vessel, the nerve beside damage reason location Kirschner wire.
The content of the invention
For above-mentioned problem and shortage, the present invention provides a kind of structure design, rationally compact, it is possible to increase operation
Efficiency, reduces the minimally invasive tunnel dilator of gasbag-type of postoperative complication.
To solve the above problems, being adopted the technical scheme that：
A kind of minimally invasive tunnel dilator of gasbag-type, including inner sleeve and outer tube, the inner of the inner sleeve is arranged with gas
Delivery pipe is connected with capsule, the air bag；The outer tube matching is set on the outside of inner sleeve corresponding with air bag, the overcoat
Pipe includes the contraction support set component and the sliding latch component positioned at two ends of the ring-type positioned at middle part, and the contraction supports set group
Part includes the contraction unit that multiple left connecting rods being pivotally connected by middle part and right connecting rod are formed, and multiple contraction unit head and the tail pivot joints form water chestnut
Shape is latticed to shrink support set component；The sliding latch component includes two outer sliding sleeves and the front and rear correspondence that left and right is correspondingly arranged
Two inner sliding sleeves set, inner sliding sleeve two ends matching is set in two outer sliding sleeves, and at outer sliding sleeve two ends, inwall is described interior in convergence mouth
It is provided with the outer wall of sliding sleeve two ends and tightens up projection.
The delivery pipe is connected with physiological saline mechanism or air pump.
Standing groove corresponding with delivery pipe is provided with the inner sleeve pipe outer wall.
Locking groove is provided with the inwall at the outer sliding sleeve two ends.
Using above-mentioned technical proposal, acquired beneficial effect is：
Reasonable in design of the present invention, compact, it is expanded by using air bag so as to realize the structure of minimally invasive passage expansion,
Realize from internal extended, so as to prevent the vital tissues such as the blood vessel and nerve of surrounding from sustaining damage, substantially increase operation and implement
Efficiency and effect, it is to avoid the generation of postoperative complication.The present invention is employed brand-new minimally invasive logical in surgical procedure is implemented
Theory is expanded in road, so that the quality entirely performed the operation has obtained effective raising.

Embodiment
With reference to specific embodiment and accompanying drawing, the present invention is described in more detail, but the invention is not restricted to these implementations
Example.
Referring to Fig. 1-Fig. 6, a kind of minimally invasive tunnel dilator of gasbag-type of the invention, including inner sleeve 1 and outer tube 2, it is described
The inner of inner sleeve 1 is arranged with air bag 3, the air bag 3 and is connected with delivery pipe 4；The matching of outer tube 2 is set in and air bag
The 3 corresponding outsides of inner sleeve 1, the outer tube 2 includes the contraction support set component of the ring-type positioned at middle part and positioned at two ends
Sliding latch component, the contraction support set component includes the contraction that multiple left connecting rods 5 being pivotally connected by middle part and right connecting rod 6 are formed
Unit, multiple contraction unit head and the tail pivot joints form the contraction support set component of rhombus net trellis；The sliding latch component includes
Two outer sliding sleeves 8 and front and rear two inner sliding sleeves 7 being correspondingly arranged that left and right is correspondingly arranged, it is outer sliding that the matching of the two ends of inner sliding sleeve 7 is set in two
It is in be provided with to tighten up projection 9 on convergence mouth, the two ends outer wall of inner sliding sleeve 7 in the two ends inwall of outer sliding sleeve 8, delivery pipe connects in set 8
It is connected in physiological saline mechanism or air pump, the inner sleeve pipe outer wall and is provided with standing groove corresponding with delivery pipe, outer sliding sleeve
Locking groove 10 is provided with the inwall at two ends.
Its extension Principle is：After the completion of positioning Kirschner wire positioning is placed, outer tube is inserted with inner sleeve along Kirschner wire, then
Gases at high pressure or physiological saline are injected into air bag by delivery pipe, air bag swell therewith, outer tube expands therewith to be strutted, position
Inner sliding sleeve and outer sliding sleeve in the sliding latch component at two ends slide expansion relatively, after extreme position is expanded to, inner sliding sleeve
On the raised convergence with outer sliding sleeve end mouthful matching extruding of tightening up engage and tighten up so that contraction support set component opens and is in
It is spherical and fixed, so that the nervus vasculairs around Kirschner wire are pushed open or peeled off, now drawable inner sleeve..
Reasonable in design of the present invention, compact, it is expanded by using air bag so as to realize the structure of minimally invasive passage expansion,
Realize from internal extended, so as to prevent the vital tissues such as the blood vessel and nerve of surrounding from sustaining damage, substantially increase operation and implement
Efficiency and effect, it is to avoid the generation of postoperative complication.The present invention is employed brand-new minimally invasive logical in surgical procedure is implemented
Theory is expanded in road, so that the quality entirely performed the operation has obtained effective raising.
The invention is not limited in above-mentioned embodiment, those skilled in the art can also make a variety of changes accordingly,
But it is any all to cover within the scope of the claims with equivalent or similar change of the invention.
