Abstract
The utility model discloses an integrated structural outer tube and saccule and belongs to the field of the interventional medical device. The integrated structural outer tube and saccule is characterized in that: an outer tube and a saccule are integrated into one body; materials of the outer tube and the saccule are polyurethane elastomers; and the integrated structural outer tube and saccule is integrally produced by adopting a plastic hollow blow molding method. As no welding point is arranged between the outer tube and the saccule, the phenomenon that the hardness and the size are increased cannot occur at the joint of the outer tube and the saccule, and the problems that in the prior art, the outer tube and the saccule of a vertebral balloon catheter are separated, the connection effect is bad, the size of a near end of the saccule is large, etc. are solved. In the interventional minimally invasive surgery, the saccule enters the vertebral lesions more easily so as to reduce the operation time, reduce the operation risk and guarantee the operation quality. The integrated structural outer tube and saccule is used for the vertebral balloon catheter, and can be widely applied to the interventional minimally invasive surgical treatment of the compressed fractures of lumbar vertebral body or thoracic vertebral body of the human body.
Description
Technical field
This utility model belongs to the interventional medical instrument field, particularly a kind of outer tube of integral structure and sacculus.
Background technology
(percutaneous kyphoplasty, PKP) treatment compression fracture of vertabral body are present the most frequently used methods to protruding urethroptasty behind the percutaneous vertebral body.Main operating theater instruments is the vertebral body foley's tube.But the outer tube of the vertebral body foley's tube of prior art and sacculus are two parts independently, outer tube and sacculus are that different materials is made, perhaps make respectively for commaterial, with welding or bonding method outer tube is connected with sacculus during assembling, as shown in Figure 1, the material at pad 3 places between outer tube 2 and the sacculus 1 is in conjunction with making its hardness, size and springform quantitative change big, connect weak effect, the near-end size of sacculus is big, when operation is used, sacculus enter vertebral body when passing pathological changes trafficability characteristic relatively poor, cause operation risk easily.Therefore needing a kind of outer tube and sacculus is the vertebral body foley's tube of one, improves the trafficability characteristic that sacculus enters vertebral body with this, reduces operation risk.
The utility model content
The purpose of this utility model is to adopt welding or bonding the connection for the outer tube that solves vertebral body foley's tube of the prior art with sacculus, during operation is used, sacculus enter vertebral body when passing pathological changes trafficability characteristic relatively poor, cause the problem of operation risk easily, special outer tube and the sacculus that proposes a kind of integral structure is characterized in that outer tube 2 and sacculus 1 are one.
The material of described outer tube 2 and sacculus 1 is polyurethane elastomer (TPU).
Described outer tube 2 and sacculus 1 adopt the integrated making of plastic hollow blow molding method.
The beneficial effects of the utility model are, because the outer tube of vertebral body foley's tube and sacculus are with the integrated making of commaterial, there is not pad between outer tube and the sacculus, the junction of outer tube and sacculus hardness and size can not occur and become big phenomenon, solved that the outer tube of vertebral body foley's tube separates with sacculus in the prior art, connect weak effect, problem such as the near-end size of sacculus is big.Sacculus is more easy when entering the vertebral body pathological changes in the operation, thereby has reduced operating time, has reduced operation risk, has ensured the operation quality.
Description of drawings
Fig. 1 is the outer tube and the sacculus welding sketch map of prior art.
Outer tube that Fig. 2 is integrated and sacculus sketch map.
Among the figure, 1--sacculus, 2--outer tube, 3--pad.
The specific embodiment
Fig. 1 is outer tube and sacculus welding sketch map, the outer tube that Fig. 2 is integrated and the sacculus sketch map of prior art.As shown in Figure 2, sacculus 1 and outer tube 2 are one, do not have pad between the two.The material of sacculus 1 and outer tube 2 is polyurethane elastomer (TPU), makes of the plastic hollow blow molding method.
When intervention property Minimally Invasive Surgery, because the vertebral body foley's tube has used the outer tube and the sacculus of integral structure, there are not as shown in Figure 1 sacculus and the pad between the outer tube 3, have good flexibility and uniformity, when operation is used, sacculus can arrive lesion smoothly, has reduced operation risk, has improved the operation quality.
This utility model is used for the vertebral body foley's tube, can be widely used in the intervention Minimally Invasive Surgery treatment of human body lumbar vertebra or thoracic vertebra compression fracture of vertabral body.
Claims (3)
