Description

Orthopedic cement mixing kit

This creation department is about a kind of cement mixing set for orthopedics, which can make the cement mixing procedure for orthopedics more convenient.

Orthopedic cement is commonly used in a variety of orthopedic operations. The materials are divided into two categories. The first type is acrylic polymer. The indications include knee replacement, spinal compression fracture, etc. These materials have a fixed support function and are more viscous. And the polymerization reaction generated during curing will generate high temperature, will not be absorbed in the human body, and will always exist.

Another type of material is a combination of calcium phosphate salts or calcium sulfate. These materials do not have the supporting effect and can only temporarily fill the bone defect to avoid secondary damage. After being implanted into the human body, such materials will be gradually decomposed and replaced by autologous bones. Common indications such as bone cancer resection, comminuted wrist fracture, and peripheral reinforcement of bone nail plate.

The materials of the above two kinds of orthopedic cements have several identical characteristics, and have a powder and a liquid agent. After the powder is mixed, it will gradually solidify. It must be filled into the target before curing. The operation can be performed by injection or direct filling. The method of injection is called minimally invasive surgery, which can reduce the size of the wound and reduce the pain of the patient.

Traditional orthopedic cement mixing sets have many accessories, which are difficult to operate and often need Surgery is performed in multiple steps or in multiple steps. If the material cures too quickly, it may cure without being used. Therefore, there is a need for a stirring kit that simplifies the operation procedure.

This creation is a cement mixing set for orthopedics, which can be easily stirred by users.

The creation has a stirring cup and a syringe, the mixing cup has a receiving groove and a groove structure, and the syringe comprises a push rod and a syringe body. When using, firstly separate the push rod of the syringe and the injection barrel body, and then fix the injection barrel body on the groove structure of the stirring cup, and then pour the powder and the liquid agent into the receiving tank, and use any suitable stirring rod. After stirring and stirring, the mud is excavated and placed into the injection cylinder body which has been fixed in the groove structure of the mixing cup, and the stirring cup and the injection barrel body are separated by using the barb grip as a point of application, and then the push rod and the injection are separated. The barrel is used in combination.

With the creation of the mixing set, it can be operated by one person, which effectively simplifies the operation procedure of the cement for orthopedics.

In order to make the above and other objects, features, advantages and implementations of the present invention more obvious and easy to understand, the detailed description of the accompanying drawings is as follows: FIG. 1 is a schematic view of a stirring cup according to the present invention.

Figure 2 is a schematic view of a syringe according to the present invention.

Figure 3 is a schematic view showing the combination of the stirring cup and the injection body according to the present invention.

Referring to FIG. 1 , FIG. 2 and FIG. 3 , the present invention is a mixing set for cement for orthopedics, the set has a stirring cup 100 and a syringe 110, and the mixing cup 110 has a capacity. The height h2 of the groove structure 100b and the groove structure 100b shall not be higher than the height h1 of the receiving groove 100a. The syringe 110 has a pusher 110a and a syringe body 110b. The syringe body 110b has a barb grip 120 for use as a point of application when the syringe body 110b and the agitating cup 100 are separated. The accommodating tank 100a is a space for agitating the powder and the liquid agent, and a groove wall 100c is provided on the side of the accommodating groove 100a for scraping the mud. In use, the push rod 110a of the syringe 110 and the injection barrel body 110b are separated first, and the injection barrel body 110b is tightly coupled with the groove structure 100b, so that the injection barrel body 110b stands upright on the groove structure 100b of the agitating cup 100, so that The user can conveniently put the orthopedic cement which is stirred in the holding tank 100a into the injection cylinder 110b. Finally, the injection cylinder 110b and the agitating cup 100 are separated by the barb grip 120, and the push rod 110a is used in combination with the injection cylinder 110b.
