Problems solved by technology

[0003] The bone fragments in spinal fusion are generally cut into small particles by bone crushers or surgical scissors. The bone powder used to fill the small gaps between bone crushing particles cannot be obtained, and the bone crushing forceps or surgical scissors are time-consuming and laborious during the bone crushing process and cause bone fragments to scatter, which is not conducive to efficient bone crushing
[0004] High-efficiency mechanized equipment is also used in spinal fusion to solve the problem of bone crushing forceps or surgical scissors. However, its movement structure is complex and prone to blockage, thereby reducing the efficiency of bone crushing

Embodiment Construction

[0043] The accompanying drawings are all schematic diagrams of the implementation of the present invention, so as to understand the principle of structural operation. The specific product structure and proportional size can be determined according to the use environment and conventional technology.

[0044] Such as figure 1 , 2 As shown, it includes a support plate 1, a base 2, a funnel A3, a stab-removing rotator 6, a funnel B13, an electric drive module A10, and a bone crushing mechanism 17, wherein figure 1 As shown, the bone crushing mechanism 17 is installed on the base 2 through two symmetrically distributed support plates 1, and the crushed bones coming out of the bone crushing mechanism 17 are screened by the funnel A3 installed below to carry out the separation of bone crushing particles and bone crushing powder. Separation and collection: the broken bone particles screened by the funnel A3 enter the trumpet-shaped stab-removing gyratory 6 driven by the electric dri...

Abstract

The invention belongs to the field of spinal surgery, and particularly relates to a spinal surgery auxiliary device. The spinal surgery auxiliary device comprises supporting plates, a base, a funnel A, a deburring rotary body, a funnel B, an electric drive module A and a bone breaking mechanism, wherein the bone breaking mechanism is mounted on the base through the two symmetrically distributed supporting plates, and broken bones coming out of the bone breaking mechanism are screened by the funnel A mounted below to separate and collect broken bone particles and broken bone powder. The motionstructure of the spinal surgery auxiliary device is simple, due to the structural characteristics of the bone breaking mechanism, the problem of blockage of the broken bone particles cannot occur, andthus the bone breaking efficiency is effectively improved.

Description

technical field [0001] The invention belongs to the field of spinal surgery, in particular to an auxiliary device for spinal surgery. Background technique [0002] At present, spinal fusion is still the main method for the treatment of spinal diseases. It is widely used in spinal instability, degeneration, trauma, tumor and infection, and has achieved a certain effect and prognosis. The main method of spinal surgery is to take autologous bone tissue Bone grafting is mainly used. The advantage is that the bone cells in the autologous bone tissue are all surviving autologous bone cells, which have good biological properties and are conducive to bone fusion. The structure and biomechanical properties of the autologous bone meet the needs of bone grafting, and there is no rejection, biophase Good capacity. In spinal fusion surgery, it is necessary to cut the autogenous bone into small particles, and the obtained bone particles are used for filling and supporting between adjacen...
