Abstract
The utility model provides a vertebral body expansion balloon catheter and relates to a surgical instrument for curing compression fracture of a vertebral body. The vertebral body expansion balloon catheter comprises an irregular-shaped expandable balloon, an inner catheter, an outer catheter, a Y-shaped handle, a developing mark, a supporting wire and a supporting wire handle. The inner catheter is inserted in the outer catheter, the rear portion of the outer catheter is inserted in the Y-shaped handle in sealing mode, the irregular-shaped expandable balloon is arranged on the front portion of the outer catheter in sealing mode, the developing mark is arranged inside the irregular-shaped expandable balloon in the inner catheter, the supporting wire is injection-molded in the supporting wire handle, inserted into the inner catheter through the Y-shaped handle and used for supporting inner catheter and preventing the inner catheter from deforming. The irregular-shaped expandable balloon is composed of a reinforcing rib made of fiber and the expandable balloon, and the reinforcing rib is injection-molded inside the expandable balloon. The reinforcing rib of the irregular expandable balloon is made of carbon fiber, macromolecular polyethylene fiber, a memory alloy wire or a plastic nylon material.
Description
Technical field
What this utility model balloon catheter for expanding vertebra related to is a kind of being used for the treatment of because the surgical instruments of compression fracture of vertabral body.
Background technology
The pain that compression fracture of vertabral body causes has become the serious problems that patient and family members even clinician thereof face, and the patient is because suffering for a long time pain devitalization function.The traditional Therapeutic Method of compression fracture of vertabral body comprises the application of bed, analgesic drug product and brace, but these methods are slower to the alleviation of pain.Long-term pain will cause patient's daily routines limited, and cause gradually the decline of self-care ability and the forfeiture of self-confidence.
Until vertebroplasty occurs; this problem is just solved more satisfactoryly; and be applied to gradually clinical; but the deficiency of some apparatus self also reveals gradually; as topmost instrument in the vertebroplasty process: poor controllability often can appear strutting power inadequate, in balloon catheter for expanding vertebra; sacculus easily breaks, and the art Fracture is difficult to the problems such as taking-up.
Summary of the invention
The purpose of this utility model is to provide a kind of balloon catheter for expanding vertebra for above-mentioned weak point, and balloon catheter for expanding vertebra is reasonable in design, and is simple in structure, performs the operation easy for installation, reduces patient's misery, is convenient to post-operative recovery.Balloon catheter for expanding vertebra makes the corpus vertebrae replacement of compression fracture and forms cavity, fills bone cement, increases the Rigidity and strength of vertebral body, rebuilds.
This utility model balloon catheter for expanding vertebra takes following technical scheme to realize: balloon catheter for expanding vertebra comprises special-shaped balloon-expandable, inner catheter, outer catheter, Y shape handle, development sign, supporting wire and supporting wire handle.Inner catheter plugs in outer catheter, the outer catheter rear seal plugs in the Y shape handle, the sealing of abnormity balloon-expandable 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, plugs in inner catheter by the Y shape handle, be used for supporting, prevent the inner catheter distortion.
Reinforcement and balloon-expandable that the abnormity balloon-expandable is made by fiber form, 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, the 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 by the Y shape handle, it is inner that the reinforcement of the various shapes that fiber is made injects balloon-expandable by injection mold with the reinforcement of various shapes, and simultaneously sealing is installed on the outer catheter.The reinforcement of abnormity balloon-expandable can be selected the materials such as carbon fiber, high polymer polyethylene fiber, memory alloy wire or plastic nylon, the reinforcement material of special-shaped balloon-expandable is woven into circle according to the operation needs, oval, square or special-shaped shape, utilize injection mold, polyether-modified polyamide material is annotated in the reinforcement surface, formed special-shaped ball scrotiform shape.
Operation principle
Utilize the related surgical instrument to get through service aisle in patient's vertebral body affected part, choosing operation needs the balloon catheter for expanding vertebra of shape, balloon catheter for expanding vertebra after the extracting vacuum is inserted vertebral body inside, utilize the increase contrast agent to expand gradually balloon catheter for expanding vertebra, until reach 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:
Balloon catheter for expanding vertebra is reasonable in design, and is simple in structure, performs the operation easy for installation, reduces patient's misery, is convenient to post-operative recovery.Balloon catheter for expanding vertebra makes the corpus vertebrae replacement of compression fracture and forms cavity, fills bone cement, increases the Rigidity and strength 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 by fibrage, can increase the shape that the vertebral body expansion forms cavity, satisfy requirements of operation, also having solved simultaneously balloon catheter for expanding vertebra, to strut power inadequate, poor controllability, sacculus easily breaks, and the art Fracture is difficult to the problems such as taking-up.
Description of drawings
The utility model is described in further detail below with reference to accompanying drawing.
Fig. 1 is structural representation under the balloon catheter for expanding vertebra evacuation state.
Fig. 2 is anterior partial enlarged drawing under the balloon catheter for expanding vertebra evacuation state.
Fig. 3 is structural representation under the balloon catheter for expanding vertebra expansion state.
Fig. 4 is anterior partial enlarged drawing under the balloon catheter for expanding vertebra expansion state.
The specific embodiment
With reference to accompanying drawing 1,2,3,4, balloon catheter for expanding vertebra comprises outer catheter 1, inner catheter 2, sign 3, reinforcement 4, special-shaped balloon-expandable, Y shape handle 6, supporting wire 7 and supporting wire handle 8 develop.Inner catheter 2 plugs in outer catheter 1, outer catheter 1 rear seal plugs in Y shape handle 6, the sealing of abnormity balloon-expandable is installed in outer catheter 1 front portion, reinforcement 4 injection moldeds are in balloon-expandable 5 inside, be positioned at special-shaped balloon-expandable interior location at inner catheter 2 and be provided with the sign 3 that develops, supporting wire 7 is injection-moulded in the supporting wire handle 8, plugs in inner catheter 2 by Y shape handle 6, be used for supporting, prevent the inner catheter distortion.
