Definitions
- the invention relates to a medical appliance, and in particular to a dilator for forming a cavity in a push body. Background technique
- Compression fractures of the spine caused by osteomyelitis are highly treatable.
- the use of bulbar device for expansion and kyphoplasty to treat spinal compression fractures has achieved satisfactory early results.
- This special ball grate device includes a balloon provided at the front end of a hollow rod body, and the rear end of the rod body is connected to a high-pressure syringe with a pressure measurement and control device and a pumping and vacuuming device.
- the percutaneous puncture is guided by the "C" arm X-ray machine through the push bow to enter the wound push, the hollow drill is drilled into the wound push under the guide of the guide pin, and a working channel is established, and then sent to the special through the working channel.
- High pressure resistant ball saccade under the observation of "C" arm X-ray machine, use a high pressure syringe with pressure measuring and control device to inject the contrast agent into the ball saccade to expand the ball saccade, restore the height of the injury and correct the kyphosis.
- the ball pupa is evacuated and exited, leaving the cavity generated after the ball pupa expands. Finally, the bone cement is injected into the cavity under low pressure to form a casting in the cavity to complete the operation.
- the bulbar expansion and push-back kyphoplasty can squeeze the collapsed cancellous bone fractured due to osteoporosis to the upper and lower end plates of the pusher and the surrounding cortex To make it compact and restore the height and shape of the wound push, and then inject bone cement into the surrounding complete cavity, so it not only increases the effectiveness of the push reset, but also fundamentally avoids the simple push push operation The potential danger caused by bone cement leakage also effectively reduces complications.
- this special ball ball needs to bear a lot of pressure during the operation, so the ball ball must be made of a special material ⁇ cattle warp special manufacturing process, and the cost is higher.
- the bulbar material does not have a clear image under the X-ray and its expansion principle, the bulbar also needs to be equipped with a high-pressure syringe with a pressure measurement and control device to inject contrast agent to make the bulbar expansion and contrast clear.
- the bulb is expanded by injecting a contrast agent
- the shape of the cavity formed by the expansion cannot be accurately controlled, depending on how small the contrast is injected.
- the shape of the chamber formed by the pressure and speed is random, which is not accurate and stable enough.
- Physicians need a lot of artificial views under the guidance of X-ray machines during plastic surgery. Observe the expansion, reduction, and injection of bone cement. Because the volume of the cavity cannot be accurately grasped, the amount of injected bone cement basically depends on the surgeon's surgical experience and can be compared with X-ray guidance. Good grasp, the operation is more difficult.
- this ball is a soft material after all. During the operation, it not only has to bear a large expansion pressure, but also touches the thorn-shaped cancellous bone, which is relatively easy to break. Rupture and the leakage of the contrast medium inside the wound will cause the operation to fail, seriously threaten the patient's health and even life safety, and there are hidden safety hazards.

- the positioning ring 522 is moved in the direction of the stopper 5211 and tightly sleeved on the outer periphery of each elastic piece 521.
- the two tubes can be restricted Relative axial position.
- the axial positioning structure 5 other structures capable of achieving axial positioning in other conventional technologies may be adopted.
- the sliding fit can also be an interference fit. Due to this tight fit, a relatively large operating force is required in the process of the two tubes moving in relative positions to form the cavity from the elastically expanded section 12 to expand outward, but This interference fit has a good axial positioning effect, and the axial positioning structure can be omitted.
- the inner tube 2 can be directly withdrawn or the outer tube 1 can be pushed out at the movable end, and a satisfactory cavity can be formed under the guidance of the scale line 23 and the X-ray machine, and the operation is very convenient and simple.
- Example 3
- Embodiments 1 and 2 This embodiment is basically the same in structure, material, principle, use process and effect as those in Embodiments 1 and 2. The same points will not be repeated, and only the differences will be described in detail.
- the two tubes in this embodiment adopt a concave-convex structure at the movable sleeve end.
- the concave-convex structure 6 includes several circumferential grooves 61 provided on the inner diameter of the outer tube 1 and a convex ring 62 provided on the outer diameter of the inner tube 2 to cooperate with the groove of the outer tube 1; or, a groove
- the positions of 61 and the convex ring 62 are interchangeable, that is, the inner diameter of the outer tube 1 is provided with several convex rings 62, and the outer diameter of the inner tube 2 is provided with a matching circumferential groove 61.
