Description
Technical field
This utility model relates to the aid for vertebral body Cement fixation in a kind of bone surgery, with directed sacculus with the use of, particularly relate to a kind of flexible directed balloon inflation channel assembly.
Background technology
Compression fracture of vertabral body sickness rate in old group is higher, the compression degree difference of subsiding of fracture site vertebral body each several part, and the position large for compression degree needs distraction reduction, and injects the implants such as bone cement and fill.Can increase vertebral body strength and stability after bone cement solidifies, the vertebral body that this guarantees recovery can not be compressed again, can not again lose vertebral height, pressuring nerve.
The directed balloon inflation channel of existing directed balloon inflation channel assembly as shown in Figure 1, its directed catch is straight, bone cement is caused easily to spread towards periphery when injecting, there is Seepage, therefore, bone cement can enter in body, may cause sufferer pulmonary infarction, nerve injury, segmental vessels damage etc.
Summary of the invention
In view of the above-mentioned defect of prior art, the purpose of this utility model is to provide a kind of use safety, simple to operate, the directed balloon inflation channel assembly of flexibility of good results.
The purpose of this utility model is achieved through the following technical solutions:
A kind of flexible directed balloon inflation channel assembly, comprises curved directed balloon inflation channel, the probe of combined probe sleeve pipe and awl.Curved directed balloon inflation channel, comprise handle, directed sleeve pipe and curved directed catch, directed inside pipe casing is the through hole of hollow, is used for installing probe or awl.Probe has probe handle, bar portion and head; The handle of probe handle and curved directed balloon inflation channel locks by spiral rotating locking mechanism; The bar portion of probe forms primarily of wirerope, and this wirerope has rigidity, can bend arbitrarily; The head of probe is made up of stainless steel material, in practice, with curved directed balloon inflation channel with the use of, curved directed balloon inflation channel is introduced pathological changes vertebral body inner, gets through passage.Awl has awl handle, bar portion and head; The bar portion of awl forms primarily of wirerope, and this wirerope has rigidity, can bend arbitrarily; The head of awl is made up of stainless steel material, in practice, with curved directed balloon inflation channel with the use of, hinge goes the inner unnecessary bony spur of vertebral body, in order to avoid after sacculus enters vertebral body inside, bony spur punctures sacculus.
Compared with the existing technology, feature of the present utility model is with progressive as follows:
1, directed balloon inflation channel component design is curved by flexibility of the present utility model directed balloon inflation channel assembly, when reducing original Cement fixation, and the risk of possible seepage, thus, and use safety, simple to operate, good results; In addition, directed expansion sacculus can reach the effect that orientation struts vertebral body.
2, the bar portion of awl of the present utility model forms primarily of wirerope, with curved directed balloon inflation channel with the use of, can bend according to the crooked position of curved directed balloon inflation channel, hinge goes the unnecessary bony spur of vertebral body internal object position.
3, the bar portion of the probe of combined probe sleeve pipe of the present utility model forms primarily of wirerope, with curved directed balloon inflation channel with the use of, can bend according to the crooked position of curved directed balloon inflation channel, directed balloon inflation channel be introduced pathological changes vertebral body inner, get through passage.

Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is further described.
A kind of flexible directed balloon inflation channel assembly, comprises curved directed balloon inflation channel 1, the probe 2 of combined probe sleeve pipe and awl 3.As shown in Figure 2, curved directed balloon inflation channel 1, comprise handle 4, directed sleeve pipe 5 and curved directed catch 6, directed sleeve pipe 5 inside is the through hole of hollow, is used for installing probe 2 or awl 3.As shown in Figure 3, probe 2 has probe handle 7, bar portion 8 and head 9; As shown in Figure 4, probe handle 7 locks by spiral rotating locking mechanism with the handle 4 of curved directed balloon inflation channel 1; The bar portion 8 of probe 2 is primarily of wirerope composition, and this wirerope has rigidity, can bend arbitrarily; The head 9 of probe 2 is made up of stainless steel material, when reality uses, with curved directed balloon inflation channel 1 with the use of, curved directed balloon inflation channel 1 is introduced pathological changes vertebral body inner, gets through passage.As shown in Figure 5, awl 3 has awl handle 10, bar portion 11 and head 12; The bar portion 11 of awl 3 is primarily of wirerope composition, and this wirerope has rigidity, can bend arbitrarily; The head 12 of awl 3 is made up of stainless steel material, in practice, with curved directed balloon inflation channel 1 with the use of, hinge goes the inner unnecessary bony spur of vertebral body, in order to avoid after sacculus enters vertebral body inside, bony spur punctures sacculus.
The operating procedure utilizing this curved directed balloon inflation channel 1 to carry out performing the operation is as follows:
1, open C arm machine, under x-ray bombardment, probe and curved directed balloon inflation channel 1 are pierced pathological changes vertebral body inner, in the process, the angle that curved directed balloon inflation channel 1 enters vertebral body inside is controlled by medical worker oneself, selects the most appropriate position; After curved directed balloon inflation channel 1 enters, not can pass over the collapsed portion of pathological changes vertebral body, in order to avoid leakage when causing follow-up bone cement to inject.
2, after having located, the probe 2 of combined probe sleeve is exited.
3, awl 3 is entered pathological changes vertebral body inside through curved directed balloon inflation channel 1, rotate awl handle 10, remove dynamic for the bony spur of curved directed balloon inflation channel 1 surrounding hinge.
4, awl 3 is exited.
5, curved directed sacculus is entered pathological changes vertebral body inside to correct position through curved directed balloon inflation channel 1.
6, after entering into affected part, pressurization is entered to sacculus.Curved directed sacculus adds pressure at dilatation pressure pump, and flare up semi-open type spheroid (towards specific direction), by External Force Acting by collapse of vertebra part jack-up, makes it return to original shape gradually.
7, remove the pressure be applied on sacculus, sacculus returns to original closure state by the spheroid heaved.Removed from curved directed balloon inflation channel 1 by sacculus, curved directed balloon inflation channel 1 still stays in vertebral body inner, invariant position.
8, the bone cement needed for modulation, when modulated bone cement is in dough period (toothpaste-like), uses the medical injector of band female Luer bone cement can be injected into vertebral body inside.Always controlled the flow direction of bone cement by the openings on curved directed balloon inflation channel 1, carry out stable fracture by filling crackle and space and bonding upper and lower soleplate.
Although described various embodiment of the present utility model in detail at this, but should be appreciated that this utility model is not limited to the detailed description of the invention described in detail and illustrate here, other modification and variant can be realized when not departing from essence of the present utility model and scope by those skilled in the art.All these modification and variant all fall in scope of the present utility model.And all components described here can be replaced by component equivalent in other technologies.
