Abstract
The invention provides a special-shaped vertebral body expansion balloon catheter, which relates to a surgical instrument used for treating compression fracture of the vertebral body and comprises a special-shaped expandable balloon, an inner catheter, an outer catheter, a Y-shaped handle, a development mark, a support wire and a support wire handle, wherein the inner catheter is arranged and inserted in the outer catheter, the back part of the outer catheter is arranged and inserted into the Y-shaped handle in a sealed way, the special-shaped expandable balloon is arranged at the front part of the outer catheter in a sealed way, the development mark is arranged in a position of the inner catheter positioned inside the special-shaped expandable balloon, the support wire is formed in the support wire handle through injection molding, is inserted and arranged in the inner catheter through the Y-shaped handle, and is used for supporting, and the inner catheter is prevented from deforming. The special-shaped expandable balloon consists of an expandable balloon and reinforcing ribs made of fiber, and the reinforcing ribs are formed inside the expandable balloon through injection molding. The reinforcing ribs of the special-shaped expandable balloon adopt carbon fiber, macromolecular polyethylene fiber, memory array wires or plastic nylon materials.
Description
Technical field
What the present invention's abnormity vertebral body expansion of balloon catheter related to is a kind of surgical instruments that is used to treat owing to compression fracture of vertabral body.
Background technology
The serious problems that the pain that compression fracture of vertabral body causes has become patient and family members even clinician and faced, the patient is because of suffer pain devitalization function for a long time.The compression fracture of vertabral body traditional treatment comprises the application of bed, analgesic drug product and brace, but these methods are slower to the alleviation of pain.Secular pain will cause patient's daily routines limited, and cause the decline of self-care ability and the forfeiture of self-confidence gradually.
Occur until vertebroplasty, this problem just is able to solve more satisfactoryly, and is applied to clinical gradually; But the deficiency of some apparatus self also reveals gradually; As topmost instrument in the vertebroplasty process: the vertebral body expansion of balloon catheter, it is not enough the power of strutting to occur through regular meeting, poor controllability; Sacculus is prone to break, and the art cleaved is difficult to problems such as taking-up.
Summary of the invention
The objective of the invention is provides a kind of special-shaped vertebral body expansion of balloon catheter to above-mentioned weak point, and special-shaped vertebral body expansion of balloon catheter is reasonable in design, simple in structure, and it is easy for installation to perform the operation, and reduces patient's misery, is convenient to post-operative recovery.Abnormity vertebral body expansion of balloon catheter resets the vertebral body of compression fracture and forms cavity, fills bone cement, increases rigidity and the intensity of vertebral body, rebuilds.
The present invention's abnormity vertebral body expansion of balloon catheter takes following technical scheme to realize: special-shaped vertebral body becomes expansion of balloon catheter to comprise special-shaped balloon-expandable, inner catheter, outer catheter, Y shape handle, development sign, supporting wire and supporting wire handle.The inner catheter dress is inserted in the outer catheter, and outer catheter rear seal dress is inserted in the Y shape handle, and special-shaped balloon-expandable sealing is installed in the outer catheter front portion; The reinforcement injection molded is inner at balloon-expandable; Be positioned at special-shaped balloon-expandable interior location at inner catheter and be provided with the sign that develops, supporting wire is injection-moulded in the supporting wire handle, is inserted in the inner catheter through Y shape handle dress; Be used for supporting, prevent the inner catheter distortion.
Reinforcement and balloon-expandable that the abnormity balloon-expandable is processed by fiber are formed, and the reinforcement injection molded is inner at balloon-expandable.The inner catheter that the sign that develops is installed is loaded in the outer catheter; Y shape taper knob is on outer catheter; Encapsulation process; The supporting wire that the supporting wire handle is housed is inserted in the inner catheter through Y shape handle, and it is inner that the reinforcement of the different shape that fiber is processed injects balloon-expandable through injection mold with the reinforcement of different shape, and sealing simultaneously is installed on the outer catheter.The reinforcement of abnormity balloon-expandable can be selected materials such as carbon fiber, high-molecular polythene fiber, memory alloy wire or plastic nylon for use; The reinforcement material of special-shaped balloon-expandable is woven into circle according to the operation needs; Ellipse, square or special-shaped shape is utilized injection mold; Polyether-modified polyamide material is annotated in the reinforcement surface, formed special-shaped sacculus shape.
Operation principle
Utilize the related surgical instrument to get through service aisle in patient's vertebral body affected part; Choosing operation needs the special-shaped vertebral body expansion of balloon catheter of shape; Insert vertebral body inside to the special-shaped vertebral body expansion of balloon catheter after the extracting vacuum; Utilize the increase contrast agent to expand special-shaped vertebral body expansion of balloon catheter gradually, until reaching the satisfied expansion effect of operation.The abnormity expansion of balloon catheter stops expansion after being expanded to and requiring degree, and extracting vacuum also shifts out special-shaped expansion of balloon catheter.
The product advantage:
Abnormity vertebral body expansion of balloon catheter is reasonable in design, simple in structure, and it is easy for installation to perform the operation, and reduces patient's misery, is convenient to post-operative recovery.Abnormity vertebral body expansion of balloon catheter resets the vertebral body of compression fracture and forms cavity, fills bone cement, increases rigidity and the intensity of vertebral body, rebuilds the stability of spinal column, reaches alleviating pain, corrects kyphosis deformity, improves patients ' life quality.And become reinforcement to soak to mould polyether-modified polyamide material to form head vertebral body sacculus through fibrage; Can increase the shape that the vertebral body expansion forms cavity; Satisfy requirements of operation, also having solved simultaneously the vertebral body expansion of balloon catheter, to strut power not enough, poor controllability; Sacculus is prone to break, and the art cleaved is difficult to problems such as taking-up.
