Crushed bone compaction device for bone grafting surgery

Abstract

The invention discloses a crushed bone compaction device for a bone grafting surgery. The crushed bone compaction device comprises a handle, a straight rod, a vibrator shell and a vibrating head, wherein the handle is internally provided with a power supply and a power supply switch connected with the power supply; the straight rod is connected below the handle, a through hole is formed at the center of the straight rod, and a lead is arranged in the through hole; the vibrator shell is connected at the lower part of the straight rod and is internally provided with an electric vibrator which is connected with the power supply by the lead in the through hole; and the vibrating head is connected below the straight rod by a spring. According to the invention, as compaction on crushed bones can be accelerated by vibration of the electric vibrator, impact and damage on normal bones can be reduced greatly, the success rate of the surgery is enhanced, and the function recovery of the crushed bones can be promoted effectively.

Description

technical field [0001] The invention belongs to the technical field of medical appliances, in particular to a crushed bone compacting device for bone implant surgery. Background technique [0002] Bone grafting is a relatively common operation. During bone grafting, bone fragments of appropriate size and shape should be taken and funnel-shaped or tubular instruments should be used to place the fragments of bone at the site requiring surgery. [0003] Due to the relatively long pipeline through which the broken bone passes, and the friction and adhesion between the bone particles and the tube wall, when the broken bone is placed in the site requiring surgery, bone grafting rods and other intrusion instruments and funnel-shaped or tubular tools with a matching shape are generally used. Instruments compact the broken bone. [0004] In the operation of implanting broken bones, the filled broken bones are required to be dense, and there must be no gaps in the middle. Otherwise, ...

AI Technical Summary

Problems solved by technology

[0004] In the operation of implanting broken bones, the filling of broken bones is required to be dense, and there must be no gaps in the middle. Otherwise, the fusion device installed in the patient's body will not be well connected with the bone, and the blood will not be able to circulate up and down, resulting in slow recovery from the operation, and even failure. complication

[0005] Existing devices for compacting broken bones such as punching instruments, in the operation of compacting broken bones, in order to ensure the compaction of broken bones, it is necessary to use the punching instrument to knock the broken bones hard. On the one hand, this simple It is difficult to ensure the compaction of the broken bone by knocking. On the other hand, it is necessary to apply a large impact force to the normal bone through the instrument, which may cause damage to the normal bone.
