Treatment Of Spinal Cord Ventral Tumors With Self-made Tension Free Retractor And Dissector

Objective: We invented a tension-free retractor and elevator,has the following characteristics: the set of instruments is the most obvious protective effect even if the use of hydrostatic pressure as the original force of distraction,because the water sac in the simulation of a not more than the normal cerebrospinal fluid pressure on the environment,the use of soft easy to deformation of the water sac.The spinal cord and attached tightly,compared with other traction.The area increased significantly,at the same pressure,the whole of the spinal cord can achieve satisfactory.The pressure increase slowly,hands need to move around 30 cm will be water sac swell to 1cm,compared with the traditional retractor,this process is very easy to get traction control,and can be directly fixed in place after the piezometric tube,fixed pressure tube of the requirements is not high,because of a soft infusion tube between the water sac and piezometric tube therefore,the piezometric tube can easily move to easy fixed position,but also can liberate a hand for operation.Spinal cord injury can be avoided by hand shaking.Now to explore the application of this kind of self-made tension opener and dissector in the operation of spinal cord ventral tumors?Methods : In this study,13 patients with cervical spinal cord tumors were treated with self-made tension-free spreader and stripper.Production methods: tension free distraction: the use of cerebrospinal fluid pressure tube and the lower end of a minus to become a straight piezometrictube,and cut off the end to be 22 cm long;cut a one-time infusion,infusion tube and funnel spare selection.The use of 6 surgical gloves,cut the little finger fingertip to become a hemispherical about 1cm in diameter,and the hemispherical infusion infusion pipe,and another end of the transfusion tube and the measuring tube are connected together to make a non Water Leakage water bag.The other end of the utility model is connected with the other end of the pressure measuring tube by using a funnel of the infusion device to form a closed system.The production of non tension stripper: the use of cerebrospinal fluid pressure tube and the lower end of a minus to become a straight piezometric tube,and cut off the end to be 22 cm long;cut a one-time infusion,infusion tube and funnel spare selection.The use of 6 surgical gloves,cut the little finger fingertip to become a hemispherical about 1cm in diameter,one end of the piezometric tube are connected together to make a non Water Leakage water bag.The other end of the utility model is connected with the other end of the pressure measuring tube by using a funnel of the infusion device to form a closed system ? Result: 13 cases of tumors and have achieved satisfactory exposure,total resection,11 cases of postoperative neurological function recovered gradually,especially one cases of cervical tumor,the symptoms were improved after surgery,lower extremity weakness to recovery is most obvious,9 cases of lower extremity weakness patients had muscle strength recovered obviously.There was no operative death.The patients were followed up for 6months.Between the spinal cord and subdural tumor at both ends of the water sac is arranged in the self-made tension-free spreader gloves made of,slowlyopen the switch and gradually adjust the piezometric pressure tube vertical,the height of the piezometric tube within the water column height of not more than20 cm.So as to achieve the purpose of tumor.Conclusion:Compared with the traditional instruments,the use of this kind of non tension spreader and dissector has obvious advantages in the ventral operation of the spinal cord.
