Abstract
The utility model relates to a vertebra dilator which comprises a transfusion conduit, wherein the front end face of the transfusion conduit is in an enclosed structure, and the back end of the transfusion conduit is provided with a liquid injection connection pipe which is communicated with the pipe chamber of the transfusion conduit. An elastic saccule is sheathed on the front section pipe wall of the transfusion conduit fixedly, and the inner chamber of the elastic saccule is communicated with the inner chamber of the transfusion conduit through holes arranged on the pipe wall of the transfusion conduit. The utility model can solve the defects of serious nerve complications caused by poor purposefulness, easy surrounding leakage occurrence, etc. in the prior art, and at the same time, the new treatment method that cement is injected into bones at ordinary pressure can be popularized and used.
Description
This utility model relates to a kind of medical apparatus and instruments, relates to a kind of vertebra dilator specifically.
Along with the raising of people's living standard and the progress of medical skill, make that the human life-span is generally prolonged, and as the also growth year by year thereupon of number of the infected of senile osteoporosis compression fracture of spine one by one of a kind of common clinically disease.According to epidemiology statistics, osteoporosis is mainly in white people and Aisan, and the total prevalence rate of Chinese women more than 50 years old is about 15%.Because compression fracture of spine is mainly in the old people, this has just brought inconvenience for the open surgery treatment.In the later stage eighties, there is individual physician once to attempt making a bet abroad and treats compression fracture of spine into the method for bone cement treatment by pedicle of vertebral arch puncture, normal pressure.Though this method is poor because of its purposiveness, and periphery leakage often takes place, and causes severe complications such as nerve, to fail to be applied, its this method that adopts normal pressure to make a bet into bone cement treatment has the saving grace that is better than the open surgery Therapeutic Method.Prove after deliberation, if can be before normal pressure be made a bet this Therapeutic Method enforcement of bone cement, adopt the expansion apparatus that the compression position is expanded earlier, and make its recovery, bone cement afterwards reinjects, then can overcome existing deficiency in the prior art, normal pressure be made a bet be able to utilization and extention into this Therapeutic Method of bone cement.
The purpose of this utility model just is to provide a kind of vertebra dilator that can expand the compression position.
The purpose of this utility model can adopt following measure to realize:
Vertebra dilator of the present utility model comprises injection catheter, the front end face of described injection catheter is an enclosed construction, its rear end is provided with the liquid that is connected with its tube chamber and injects connection tube, be set with a resilient bladder in affixed mode on described injection catheter leading portion tube wall, the inner chamber of this resilient bladder is by being arranged on the through hole on the injection catheter tube wall and the intracavity inter-connection of injection catheter.
Pressure when understanding the liquid injection for ease of grasping at any time, and can in time the gas in the injection catheter be discharged, the liquid that this utility model is connected with its tube chamber except that the rear end at described injection catheter is provided with injects the connection tube, also is provided with an exhaustor and Pressure gauge connection tube.
Principle of the present utility model and using method are as follows: before the enforcement normal pressure is made a bet this Therapeutic Method of bone cement, the mode of earlier the compression fracture of spine position being taked to hole makes dilator of the present utility model enter vertebral body, by method from liquid to resilient bladder that inject the compression position is expanded then, treat after it resiles dilator of the present utility model to be extracted out, bone cement afterwards reinjects, treat to play good supporting and restitution after the bone cement sclerosis, patient's the state of an illness is taken a turn for the better even reach the recovery from illness effect.
Application of the present utility model not only can effectively solve normal pressure make a bet in this prior art of bone cement treatment compression fracture of spine existing because of its purposiveness poor, normal periphery leakage takes place and cause the weak point of severe complications such as nerve, and normal pressure is made a bet be able to utilization and extention into this new Therapeutic Method of bone cement.
Accompanying drawing is that master of the present utility model cuts open figure.
This utility model is done with detailed description below with reference to embodiment (accompanying drawing):
Vertebra dilator of the present utility model comprises that by front end face be the injection catheter (5) that enclosed construction hollow pipe and the four-way connection (4) that combines with the hollow pipe rear end are formed, described four-way connection (4) rear end face place is provided with the liquid that is connected with the tube chamber of injection catheter (5) and injects connection tube (2), exhaustor (3), Pressure gauge connection tube (1), be set with a resilient bladder (6) in airtight affixed mode on described injection catheter (5) leading portion tube wall, the inner chamber of this resilient bladder (6) is by being arranged on the intracavity inter-connection of a plurality of through holes (7) and injection catheter (5) on injection catheter (5) tube wall.
Claims (2)
1, a kind of vertebra dilator, it is characterized in that: it comprises injection catheter (5), the front end face of described injection catheter (5) is an enclosed construction, its rear end is provided with the liquid that is connected with its tube chamber and injects connection tube (2), be set with a resilient bladder (6) in affixed mode on described injection catheter (5) leading portion tube wall, the inner chamber of this resilient bladder (6) is by being arranged on the intracavity inter-connection of through hole (7) and injection catheter (5) on injection catheter (5) tube wall.
2, vertebra dilator according to claim 1 is characterized in that: the rear end of described injection catheter (5) is provided with the liquid that is connected with its tube chamber and injects connection tube (2), exhaustor (3) and Pressure gauge connection tube (1).
