Problems solved by technology

During the operation, it is necessary to use an X-ray machine to observe the distribution of the injected bone cement in the vertebral body. Therefore, the doctor who performs this type of operation is exposed to X-ray radiation for a long time, which is extremely harmful to the health of the doctor.
[0003] In order to protect doctors from radiation hazards, a brand-new automatic bone cement injection device has been designed in the prior art, but this completely eliminates the currently widely used manual bone cement injection device, resulting in a great waste of cost and resources, which is not conducive to automatic injection. Widespread utilization of injection equipment

Embodiment 1

[0037] Such as figure 1 As shown, the existing manual bone cement injection device generally includes a perfusion tube 200 that can be inserted into the cannula 300 and a push rod 100 inserted into the perfusion tube 200 for injecting bone cement. The cannula 300 penetrates into the vertebral body 400 during vertebroplasty to form a working channel during the operation.

[0038] Such as figure 2 and image 3 As shown, the boosting device for injecting bone cement in vertebroplasty of the present invention includes a traction clamp 1 that can be clamped on the push rod 100, a positioning clamp 2 that can be clamped on the perfusion tube 200, and a clampable Fixing clip 3 on sleeve 300 .

[0039] The traction clamp 1 comprises a traction rod 11 and a hook portion 12, one end 121 of the hook portion 12 is movably connected with the traction rod 11, and the wing nut 13 which is threadedly connected to one end of the traction rod can be screwed, and the hook portion 12 This en...

Embodiment 2

[0047] Such as Figure 4 As shown, on the basis of embodiment 1, in this embodiment, two sets of automatic boosting devices for injecting bone cement in vertebroplasty in embodiment 1 are used to form a boosting system, and two sets of existing manual bone cement injection The device is automatically boosted at the same time, that is, two sets of boosting devices for injecting bone cement during vertebroplasty in Example 1 are used, and the fixing clips 3, 3a, positioning clips 2, 2a and traction clips 1, 1a are respectively clamped On the sleeve pipe 300, 300a perfusion tube 200, 200a and the push rod 100, 100a of each set of existing manual bone cement injection device, the connection and the clamping structure of the booster device for vertebroplasty injection bone cement are all consistent with the implementation It is the same as Example 1, and can automatically boost two sets of existing manual bone cement injection devices at the same time.

[0048] In order to better ...

Embodiment 3

[0051] combine figure 1 and Figure 5 As shown, the boosting device for injecting bone cement in vertebroplasty of the present invention also includes a traction clamp 1b that can be clamped on the push rod 100, a positioning clamp 2b that can be clamped on the perfusion tube 200, and a clampable As for the fixing clip 3b held on the casing 300, in this embodiment, the traction clip 1b, the positioning clip 2b, and the fixing clip 3b all use long tail clips.

[0052] One end of the pulling wire 4b is fixed on the pulling clip 1b, and the other end passes through the passage hole 221b on the positioning clip 2b and extends to connect with the control end. The control end can control the traction line by manual, electric and other means.

[0053] An adjusting piece 5b is connected between the positioning clip 2b and the fixing clip 3b. The adjusting piece 5b includes two sub-pieces that are adjustably connected together. Both sub-pieces have a chute 51b (or adjustment slot), ...

Abstract

The invention discloses an automatic boosting device and system for injecting bone cement in the vertebral plasty. The automatic boosting device for injecting the bone cement in the vertebral plasty comprises a traction clamp capable of being clamped on a pushing rod, a positioning clamp capable of being clamped on an injection pipe and a fixing clamp capable of being clamped on a drivepipe for forming an operation work passage, wherein one end of a traction line is fixed to the traction clamp, and the other end of the traction line penetrates through a passage hole in the positioning clamp and then extends to be connected with a control end; an adjustment piece is connected between the positioning clamp and the fixing clamp. The automatic boosting device for injecting the bone cement in the vertebral plasty can be directly clamped on an existing manual bone cement injecting device, realizes control over injection of the bone cement remotely, enables doctors to be out of a radiation environment, and prevents radiation injuries to the health. The automatic boosting device for injecting the bone cement in the vertebral plasty is simple in structure, low in cost, directly clamped on the existing manual bone cement injecting device to be used in a matched mode, easy and convenient to operate and easy to popularize, and does not change the existing operation method and the traditional operation instructions of doctors.

Description

technical field [0001] The invention relates to a booster device and system for injecting bone cement in vertebroplasty, belonging to the technical field of medical devices. Background technique [0002] In vertebroplasty, the doctor makes a hole in the pedicle through minimally invasive surgery, and passes the bone cement mixed with contrast agent through such as figure 1 The manual bone cement injection device shown is injected into the fracture site, and the vertebral body is supported and reset to treat the vertebral body fracture and achieve the purpose of increasing the strength of the vertebral body. During the operation, it is necessary to use an X-ray machine to observe the distribution of the injected bone cement in the vertebral body. Therefore, the doctor who performs this type of operation is exposed to X-ray radiation for a long time, which is extremely unfavorable to the health of the doctor. [0003] In order to protect doctors from radiation hazards, a bran...
