Abstract
The invention discloses a centrum expansion saccule kit, which comprises an expandable saccule, an outer sleeve, a hollow inner sleeve, a tee connector and a reinforcing wire which is held in the inner sleeve, wherein the inner sleeve is inserted into the outer sleeve, a gap is arranged between the inner sleeve and the outer sleeve, one end of the inner sleeve passes through the tee connector, a branching pipe of the tee connector and the inner cavity of the expandable saccule as well as the gap between the outer sleeve and the inner sleeve form an enclosed channel, a developing ring is arranged on the inner sleeve which is arranged in the expandable saccule, and a one-way valve is arranged on the entrance of the branching pipe of the tee connector. The saccule cannot slowly shrink along the increased operation time, and thus an operation effect is improved.
Description
Technical field
The present invention relates to a kind of vertebral body dilating sacculus external member, belong to the medical apparatus and instruments apparatus.
Background technology
At present, compression fracture of vertabral body is the sufferers of osteoporosis face most common complication, and open operation treatment wound in the past is big, and complication is many.The percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP) is a spine surgery in recent years, the rapid development of a new type of minimally invasive surgery by percutaneous vertebral body to direct injection or compression first By re-injection of bone cement balloon, bone fillers, etc., thereby enhancing the mechanical stability of the vertebra, clinical application has confirmed its stable and reliable, fast and effective treatment of Lai, and fewer complications.And vertebral body dilating sacculus external member is in micro-wound surgical operation; The bone cement process uses in order to inject; Common vertebral body dilating sacculus external member is not because the import department of the branched pipe of three-way connector is equipped with check valve, and import department leaks gas easily, and this expansible sacculus can be along with the growth of operating time; And slowly flatly fall, influenced surgical effect greatly.Summary of the invention
The objective of the invention is to overcome the defective of prior art, thereby provide a kind of sacculus can be the slowly not flat vertebral body dilating sacculus external member of falling to improve surgical effect along with the growth of operating time.
The technical scheme that realizes the object of the invention is: a kind of vertebral body dilating sacculus external member; Comprise inner sleeve, the three-way connector of balloon-expandable, trocar sheath, hollow and be placed in the reinforced wire in the inner sleeve; Inner sleeve is inserted in the trocar sheath; Have the gap between inner sleeve and the trocar sheath, an end of inner sleeve passes three-way connector, and the gap between the branched pipe of three-way connector and the inner chamber of balloon-expandable and trocar sheath and the inner sleeve constitutes a closed channel; The inner sleeve that is positioned at balloon-expandable is provided with the ring that develops, and the import department of the branched pipe of described three-way connector is equipped with check valve.
Further, described balloon-expandable is half male-type sacculus.
After having adopted technique scheme, the present invention who takes out flat balloon-expandable is inserted service aisle, through in the X image, watching the position of the ring that develops; Thereby determine whether to arrive operative site, on check valve, connect compression pump then, carry out the fluid injection dilation procedure; Extract reinforced wire then; Inject bone cement from its afterbody, then take out flat balloon-expandable, transfer to the present invention can accomplish operation; The design of check valve makes the liquid that can not in the balloon-expandable that struts flow backwards out among the present invention, has improved surgical effect widely; Balloon-expandable can be designed as has only half of expansible sacculus, is applicable to that the affected part only needs half of situation about propping up, and has saved operating time.
Description of drawings
Fig. 1 is the structural representation of first kind of structure of vertebral body dilating sacculus external member of the present invention;
Fig. 2 is the I place amplification view of Fig. 1;
Fig. 3 is the structural representation of second kind of structure of vertebral body dilating sacculus external member of the present invention.
The specific embodiment
For content of the present invention is expressly understood more easily, below according to specific embodiment and combine accompanying drawing, the present invention is done further detailed explanation,
Embodiment one
Like Fig. 1, shown in 2; A kind of vertebral body dilating sacculus external member; Comprise inner sleeve 3, the three-way connector 4 of balloon-expandable 1, trocar sheath 2, hollow and be placed in the reinforced wire 5 in the inner sleeve 3, inner sleeve 3 is inserted in the trocar sheath 2, has the gap between inner sleeve 3 and the trocar sheath 2; One end of inner sleeve 3 passes three-way connector 4; Gap between the branched pipe 4-1 of three-way connector 4 and the inner chamber of balloon-expandable 1 and trocar sheath 2 and the inner sleeve 3 constitutes a closed channel, and the inner sleeve 3 that is positioned at balloon-expandable 1 is provided with the ring 6 that develops, and the import department of the branched pipe 4-1 of three-way connector 4 is equipped with check valve 7.
Embodiment two
As shown in Figure 3; A kind of vertebral body dilating sacculus external member; Comprise inner sleeve 3, the three-way connector 4 of balloon-expandable 1, trocar sheath 2, hollow and be placed in the reinforced wire 5 in the inner sleeve 3, inner sleeve 3 is inserted in the trocar sheath 2, has the gap between inner sleeve (3) and the trocar sheath 2; One end of inner sleeve 3 passes three-way connector 4; Gap between the branched pipe 4-1 of three-way connector 4 and the inner chamber of balloon-expandable 1 and trocar sheath 2 and the inner sleeve 3 constitutes a closed channel, and the inner sleeve 3 that is positioned at balloon-expandable 1 is provided with the ring 6 that develops, and the import department of the branched pipe 4-1 of three-way connector 4 is equipped with check valve 7.Balloon-expandable 1 is half male-type sacculus.
Operation principle of the present invention is following:
The present invention who takes out flat balloon-expandable 1 is inserted service aisle, encircle 6 position through in the X image, watching developing, thereby determine whether to arrive operative site; On check valve 7, connect compression pump then; Carry out the fluid injection dilation procedure, extract reinforced wire 5 then, inject bone cement from its afterbody; Then take out flat balloon-expandable 1; Transfer to the present invention can accomplish operation, the design of check valve 7 makes the liquid that can not in the balloon-expandable 1 that struts flow backwards out among the present invention, has improved surgical effect widely; Balloon-expandable 1 can be designed as has only half of expansible sacculus, is applicable to that the affected part only needs half of situation about propping up, and has saved operating time.
Above-described specific embodiment; The object of the invention, technical scheme and beneficial effect have been carried out further explain, and institute it should be understood that the above is merely specific embodiment of the present invention; Be not limited to the present invention; All within spirit of the present invention and principle, any modification of being made, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
