Problems solved by technology

However, percutaneous vertebroplasty also has certain shortcomings and deficiencies, that is, on the one hand, injecting bone cement through a puncture needle can easily cause bone cement leakage and cause various complications; on the other hand, this technique can only partially relieve pain, The height of the vertebral body cannot be restored, and at the same time, greater pressure is required when injecting bone cement, which is likely to cause other injuries to the patient

Embodiment Construction

[0015] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0016] as attached figure 1 Provided is this kind of double balloon catheter structure that the present invention relates to, and it is characterized in that: it comprises two balloon catheters A that are provided with inflatable balloon 7, balloon catheter B, and connecting two balloon catheter branch pipes 12 two-section connecting pipe 1, and a three-channel cock 2 with a one-way valve 3 is arranged between the two connecting pipes 1, thereby forming a double-sided synchronous expansion of the fracture collapse at the same time. Balloon catheter structure.

[0017] During use, by manipulating the three-channel cock 2 with a one-way valve 3, the expansion of a single balloon catheter can be realized, and the expandable balloon 7 at the end of the two balloon catheters can also be simultaneously completed. Bilateral expansion of the injured collapsed bone ...

Abstract

The invention discloses a double-sacculus catheter structure. The double-sacculus catheter structure for double-side synchronous expansion of a fracture collapse position is characterized by consisting of two sacculus catheters (A and B) provided with expandable sacculus (7), and two connecting tubes (1) for connecting two sacculus catheter branch tubes (12), wherein a three-way cock (2) with a one-way valve (3) is arranged between the two connecting tubes (1).

Description

technical field [0001] The invention relates to a medical device, in particular to a double-balloon catheter structure, which can be used as a pretreatment device before introducing media during the treatment of fractured vertebral bodies of osteoporosis patients. Background technique [0002] Vertebral fractures can lead to dysfunctional pain that lasts for several months. This pain can cause the patient to lose labor and exercise capacity, and can quickly cause loss of limb function, atelectasis and pneumonia, deep vein thrombosis and pulmonary embolism, etc. Fatal complications. In addition, vertebral body compression fractures were also the reason why many elderly people could not take care of themselves and lost the ability to live independently in the past. The use of a large amount of drug treatment often causes drug side effects and drug dependence, and most patients do not accept or cannot tolerate surgical treatment. [0003] At present, percutaneous vertebroplast...
