Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] Such as figure 1 As shown, the self-made bone graft device provided by the embodiment of the present invention includes: an outer sleeve 1 , a bone graft fragment 2 , a funnel 3 , a piston 4 , and a scale 5 .

[0022] A funnel 3 is integrally formed in the middle of the upper side of the outer sleeve 1; the outer surface of the outer sleeve 1 is engraved with a measuring scale 5. A piston 4 is clamped inside the outer sleeve 1 .

[0023] When the present invention is in use, the bone graft fragments 2 are put into the outer sleeve 1 through the funnel 3, and the amount of the bone graft fragments 2 can be determin...

Abstract

The invention belongs to the technical field of medical instruments and discloses a homemade bone grafting instrument, comprising an outer sleeve and a plug. A funnel is molded to the middle of the upper side of the outer sleeve integrally; the outer surface of the outer sleeve is carved with scales. The bone grafting instrument, with the funnel arranged on the outer sleeve, is applied to the bonesurgical instruments, grafting bone fragments are implanted easily and not easy to leak out, and thus the requirement on convenience in operation is met; with the range scale on the outer sleeve, bone grafting in positioning and quantitative manner and operating accuracy is improved by aligning the outer sleeve to the bone grafting portions and controlling the piston; without removing the outer sleeve, doctors can realize bone grafting frequently through the funnel, and thus the requirement on simplicity in operation is met.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a self-made bone grafting device. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] At present, the structure used in the traditional bone grafting device is mainly an outer sleeve and a piston. Bone graft fragments are added to the outer sleeve, and the piston pushes the bone fragments to enter the tissue. Bone grafting device is widely used in orthopedic surgery. It is an important surgical tool in clinical bone grafting surgery and an important medical equipment. However, the traditional bone grafting device cannot be used continuously during the bone grafting process, and the outer sleeve needs to be pulled out to add bone fragments, which cannot meet the convenience requirements during the operation; and the traditional bone grafting device has no funnel and measuring range, and the bone graft...
