Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical equipment, and more specifically, to a high-pressure injection bone cement filler. Background Art
[0002] Bone cement is the common name for bone adhesive, a medical material used in orthopedic surgery. It has such a popular name because some of its physical properties and its appearance and properties after solidification are quite similar to white cement used in construction and decoration. Bone cement is often needed in percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP).
[0003] Traditional bone cement fillers have the following shortcomings: During use, traditional bone cement fillers generally use a push rod to push bone cement out of the sleeve, but the outlet hole at the bottom of the sleeve is small, and the traditional sleeve is straight and non-adjustable. The injection position cannot spread to the surrounding area, and the diffusion of bone cement cannot be controlled, resulting in a high risk of leakage. Therefore, a high-pressure injection bone cement filler is needed. Utility Model Content
[0004] In order to overcome the deficiencies of the prior art, the utility model provides a high-pressure injection bone cement filler, which has the advantage of uniform injection.
[0005] To achieve the above object, the utility model provides the following technical solution: a high-pressure injection bone cement filler, comprising:
[0006] Sleeve one, sleeve two is movably installed below the sleeve one, a connecting groove is provided on the bottom surface of the sleeve one, a limiting groove is provided inside the connecting groove, a limiting circular block is rotatably installed inside the limiting groove, a connecting circular block located inside the connecting groove is fixedly installed below the limiting circular block, and sleeve two located below the sleeve one is fixedly installed below the connecting circular block.
[0007] As a preferred technical solution of the utility model, a push rod is movably sleeved inside the sleeve 1, and a screw is fixedly installed at the bottom end of the push rod.
[0008] As a preferred technical solution of the utility model, injection ports are provided on both sides of the bottom of the sleeve one, and a screw groove is provided inside the upper end of the sleeve one.
[0009] As a preferred technical solution of the utility model, a handle 2 is fixedly installed above the push rod, and a Luer interface is provided below the handle 2.
[0010] As a preferred technical solution of the utility model, a handle one is fixedly installed above the sleeve one, and a Luer connector is fixedly installed above the handle one.
[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0012] The utility model inserts the second sleeve into the patient's body, and then inserts the push rod into the interior of the first sleeve, so that the screw rod contacts the screw groove, drives the injection port to rotate, and evenly fills the bone cement into the patient's body. Compared with the traditional bone cement filler, the high-pressure injection bone cement filler drives the injection port to rotate by the contact between the screw rod and the screw groove, thereby evenly filling the bone cement into the patient's body, thereby improving the practicality of the bone cement filler.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] like Figures 1 to 6 As shown, the utility model provides a high-pressure injection bone cement filler, comprising:
[0022] A sleeve 1, a sleeve 2 4 is movably installed below the sleeve 1, a connecting groove 11 is provided on the bottom surface of the sleeve 1, a limiting groove 12 is provided inside the connecting groove 11, a limiting round block 14 is rotatably installed inside the limiting groove 12, a connecting round block 13 located inside the connecting groove 11 is fixedly installed below the limiting round block 14, and a sleeve 2 4 located below the sleeve 1 1 is fixedly installed below the connecting round block 13.
[0023] When the bone cement filler is needed, first hold the handle 1 2 with one hand, push the sleeve 1 to insert the sleeve 2 4 into the patient's body, then hold the handle 2 7 with one hand, insert the push rod 6 into the inside of the Luer connector 3, extend the push rod 6 to the inside of the sleeve 1, contact with the bone cement, and push the bone cement downward. When the screw 9 contacts the screw groove 10, it will drive the sleeve 1 to rotate, drive the injection port 5 to rotate in the patient's body, and evenly fill the bone cement into the patient's body.
[0024] By inserting the sleeve 2 4 into the patient's body and then inserting the push rod 6 into the interior of the sleeve 1, the screw 9 is brought into contact with the screw groove 10, driving the injection port 5 to rotate, and the bone cement is evenly filled into the patient's body. Compared with the traditional bone cement filler, this high-pressure injection bone cement filler drives the injection port 5 to rotate by the contact between the screw 9 and the screw groove 10, thereby evenly filling the bone cement into the patient's body, thereby improving the practicality of the bone cement filler.
[0025] Among them, a push rod 6 is movably sleeved inside the sleeve 1, and a screw rod 9 is fixedly installed at the bottom end of the push rod 6.
[0026] The push rod 6 is extended to the interior of the sleeve 1, and when the screw rod 9 contacts the screw groove 10, the sleeve 1 is driven to rotate.
[0027] Injection ports 5 are provided on both sides of the bottom of the sleeve 1 , and a screw groove 10 is provided inside the upper end of the sleeve 1 .

[0029] A handle 2 7 is fixedly mounted above the push rod 6 , and a Luer interface 8 is provided below the handle 2 7 .
[0030] Place the push rod 6 inside the sleeve 1, and then push the handle 2 7 so that the handle 2 7 drives the push rod 6 to move downward inside the sleeve 1.
[0031] Among them, a handle 1 2 is fixedly installed above the sleeve 1, and a Luer connector 3 is fixedly installed above the handle 1 2.
[0032] By means of the handle 12 disposed above the sleeve 1, the medical staff can fix the sleeve 1 by holding the handle 12, which makes it convenient for the medical staff to use the cement filler.
[0033] The working principle and use process of this utility model:
[0034] When the bone cement filler is needed, first hold the handle 1 2 with one hand, push the sleeve 1 to insert the sleeve 2 4 into the patient's body, then hold the handle 2 7 with one hand, insert the push rod 6 into the inside of the Luer connector 3, extend the push rod 6 to the inside of the sleeve 1, contact with the bone cement, and push the bone cement downward. When the screw 9 contacts the screw groove 10, it will drive the sleeve 1 to rotate, drive the injection port 5 to rotate in the patient's body, and evenly fill the bone cement into the patient's body.
