Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, and more specifically, to a bone grafting instrument with a bag. Background Art

[0002] With the development of science and technology, the field of medical device technology is also constantly innovating. Bone grafting medical devices are a kind of supporting equipment for assisting bone grafting. During bone grafting, bone grafting instruments are used to implant bone tissue into the patient's body where the bone is defective and needs to be strengthened or fused. However, existing bone grafting medical devices have certain disadvantages when used. First of all, the artificial bone currently implanted is pressed in by a bone grafting device, which has a supporting force, and the operation using a bone grafting device is more troublesome.

[0003] The utility model patent with patent publication number CN202320130071.8 discloses a bone grafting instrument with a pouch, including a bone grafting instrument, and the end of the bone grafting instrument is inserted into the necrotic part of the femoral head on the femoral head for operation, a bone grafting end is integrally formed at one end of the bone grafting instrument, and an instrument seat is integrally formed at the other end of the bone grafting instrument, and a positioning ring is positioned at the end of the bone grafting end. The bone grafting instrument with a pouch described in the utility model has a pouch positioned at the front end of the instrument, which is convenient for collecting and placing bone cement and injecting it into the necrotic part of the femoral head. The shaping of the bone cement plays a role in supporting the femoral head, and the pouch and the instrument are provided with a twist-off and detaching structure, which is convenient for removing the instrument, and is more practical.

[0004] However, in actual use, the switch twist-off structure in the prior art is inconvenient to use because the pouch needs to be implanted inside the patient's body. The pouch is implanted in different locations, so the switch twist-off structure cannot be used in some locations, and its scope of application is relatively small. Utility Model Content

[0005] In order to overcome the above defects of the prior art, the utility model provides a bone grafting instrument with a bag to solve the problems raised in the above background technology.

[0010] Through the above scheme, it can be seen that a fixed clamping ring is provided on one side of the pouch, and a clamping groove provided on the surface of one side of the fixed clamping ring is engaged with a fixed block and an extension block on one side of the connecting ring, thereby improving the connection strength between the bone grafting instrument and the pouch. At the same time, the bone grafting instrument and the pouch can be quickly separated by rotating the bone grafting instrument, thereby improving the convenience of the device.

[0011] Technical effects and advantages of the utility model:

[0012] 1. By setting an extension shearing component, a fixed ring is set at one end of the bone grafting instrument, and the electric telescopic rod on one side of the fixed ring is controlled to drive the movable ring to extend. Then, when the bag is located at a position with a small space, the movable ring is driven to extend toward the position of the bag by controlling the electric telescopic rod until the surface of one side of the movable ring extends to fit with the surface of one side of the fixed clamp ring, and then the electric push rod is controlled to drive the arc blade to cut the feed port on one side of the bag, thereby realizing the twisting-off function and improving the practicality of the device;

[0013] 2. By setting a fixed clamp ring, compared with the prior art, a fixed clamp ring is set on one side of the pouch, and the clamping groove set on the surface of one side of the fixed clamp ring is engaged with the fixed block and the extension block on one side of the connecting ring, thereby improving the connection strength between the bone grafting instrument and the pouch. At the same time, the bone grafting instrument and the pouch can be quickly separated by rotating the bone grafting instrument, thereby improving the convenience of the device.
