Abstract
The utility model relates to a vertebral body expanding balloon, which comprises an expansion balloon body, an external catheter, a support tube accommodated in the external catheter and a tee connector. One branch tube of the tee connector forms a closed channel together with the external catheter, the support tube and the balloon body, and the middle part of the external catheter is provided with two limiting sign rings. The utility model has the advantages of simple structure and convenient and rapid operation, and can reduce the frequency of using the X-ray fluoroscopy by the doctor, improve the surgical efficiency, and ease the pain of the patient during surgery.
Description
Technical field
This utility model belongs to medical instruments field, is specifically related to a kind of to the pretreatment unit before the fractured vertebral body importing medium.
Background technology
In China's aged tendency of population process, compression fracture of vertabral body increases gradually, and traditional Therapeutic Method has two kinds of non-operative treatment and operative treatments.Non-operative treatment comprises lies up, obey analgesic drug product and wear orthopedic brace, its complication is that vertebral height descends, deformity of spine (back is protruding or lateral bending is lopsided), pulmonary function descends, and chronic pain, age, relevant mortality rate rose 30%, and therefore, the key of treatment compression fracture of vertabral body is rapid pain relieving and recovers vertebral height; And traditional open surgery wound is big, and inside-fixture easily takes place looseningly, and the contiguous vertebral body of pathological changes can only provide a relatively poor anchoring condition, and may cause the grappling vertebral fracture.After adopting the treatment of percutaneous vertebroplasty, patient's pain obtains to alleviate, but this Therapeutic Method does not solve the kyphosis deformity that vertebral compression fracture causes.Kyphosis can have a negative impact in many aspects.Kyphosis makes patient's heavy burden center reach, so that patient's disequilibrium, has increased the danger of falling down, thereby injured potential probability is increased.The bear a heavy burden change at center of patient has also strengthened the load that vertebral body is born, and vertebral body is fractured easily.In order to alleviate or to eliminate kyphosis deformity, produced a kind of new operation method at present, be called the protruding plasty in back.This method is that the device percutaneous of sacculus sample is inserted compression fracture, this device is expanded, thereby raise soleplate, recovers vertebral height.Existing cone expansion of balloon catheter, though can in fracture is subsided vertebral body, form the vertebral body expansion of balloon catheter of cavity, can subtract the problem of revealing when avoiding injecting bone cement, also can ease the pain, but the doctor can not get information about the sacculus body and whether enter vertebral body, increased the number of times that uses x-ray fluoroscopy to check, and operation is complicated.
Summary of the invention
For overcoming above-mentioned shortcoming, the purpose of this utility model is at the problems referred to above, and a kind of vertebral body dilating sacculus is provided, make in the operation process, can fully understand the position of sacculus body, reduce the number of times that the doctor uses x-ray fluoroscopy to check at human external, improve operation efficient, reduce patient's misery.
The technical scheme that this utility model is adopted for achieving the above object is: a kind of vertebral body dilating sacculus, comprise an open-ended sacculus body, outer catheter, be placed in stay pipe and three-way connector in the outer catheter, branched pipe of described three-way connector and outer catheter, stay pipe and sacculus body constitute a closed channel, and the middle part of described outer catheter is provided with two spacing marker loops.
This utility model is by being provided with spacing marker loop, the process that shows operation in the outside of operating theater instruments, whether the display ball utricule all enters vertebral body, it can improve operation efficient on the one hand, less patient's misery, can reduce the number of times that the doctor uses x-ray fluoroscopy to check on the other hand, more convenient to operate.
Further improvement of the utility model is: the length between described two spacing marker loops is identical with the length of sacculus body.During operation: will not expand the vertebral body dilating sacculus and insert in the expanded casing, and go forward spacing marker loop when concordant, and show that the sacculus tail end will have arrived the head of expanded casing with the expanded casing afterbody when sacculus; When sacculus being continued be advanced into the spacing marker loop in back when concordant, show that the sacculus body is in place with the afterbody of expanded casing.By above-mentioned design, can make the sacculus body arrive the affected part freely.
This utility model is provided with the ring that develops at the connecting portion of sacculus body and stay pipe, is used for X-ray check.
Easier operation when performing the operation for the doctor is cut and is difficult for skidding easier holding with a firm grip, the branched pipe cross section of the described three-way connector mechanism that is square.
In order to have increased the intensity of product, described three-way connector is provided with reinforcement.
Description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is this utility model axonometric chart.
Fig. 3 is this utility model sacculus body extended mode sketch map.
Among the figure: 1 is the booster injection end; 2 is check valve; 3 is three-way connector; 3-1 is the three-way connector branched pipe; 3-2 is a reinforcement; 4 is booster injection; 5 is outer catheter; 6,6 ' the bit flag ring that exceeds; 7 is the sacculus body; 8 are the ring that develops.
The specific embodiment
Below in conjunction with drawings and Examples this utility model is further described.
As described in Figure, this utility model vertebral body dilating sacculus is a kind of fractured vertebral body to be imported pretreatment unit before the medium, can form cavity in fractured vertebral body, comprises open-ended sacculus body 7, outer catheter 5, stay pipe and a three-way connector 3.The middle part of outer catheter 5 is provided with two spacing marker loops 6 and 6 ', and sacculus body 7 is provided with the ring 8 that develops with the connecting portion of stay pipe, and booster injection 4 is applied in the stay pipe, and total is played a supportive role.The horizontal tube structure of stay pipe and three-way connector 3 constitutes connected component, branched pipe 3-1 of three-way connector and outer catheter 5, stay pipe and closed channel of sacculus body 7 formations.The branched pipe cross section of three-way connector 3 mechanism that is square, easier hold with a firm grip and three-way connector is provided with reinforcement 3-2 that be difficult for skidding can increase the intensity of product.
In use, set up a passage that leads in the vertebra with vertebra perforator external member, the end 1 of booster injection 4 is tightened on the port of three-way connector, open check valve 2, with air extractor air in extendible sacculus body 7 and the outer catheter 5 is taken out, making the sacculus body is deflated state, so that arrive the working region by passage smoothly, when entering vertebral body inside, the vertebral body dilating sacculus is inserted in the expanded casing, when the spacing marker loop 6 ' in the outer catheter 5 is concordant with the expanded casing afterbody, show that the sacculus tail end has arrived the head of expanded casing, observe development according to fluoroscopy images and encircle 8 position, it is concordant with the afterbody of expanded casing that sacculus is continued to be advanced into spacing marker loop 6, illustrates sacculus body 7 is in place.Sacculus is pressurized to about 44PSI,, and extracts booster injection 4 out, can in vertebral body, form cavity by the service aisle withdrawing device with the position of protection sacculus.
Length between two spacing marker loops of this utility model is identical with the length of sacculus body, whether spacing marker loop clearly display ball utricule all enters vertebral body, reduce the number of times that the doctor uses x-ray fluoroscopy to check, easy to operate, save operating time, can alleviate patient's misery, have higher utility.
