Description
Technical field
The present invention relates to medical instruments field, what specifically a kind of cooperation PEEK connecting rod used holds bar device.
Background technique
Spine nail stick internal fixation operation is one of the operation for carrying out reset and the fixation of bone, in open surgery, is led to
It crosses and holds bar device connecting rod is put into pedicle screw head of a nail U-type groove.
With the development of medical technology, minimal invasive techniques are developed in spinal surgery, minimally invasive compared to open surgery
Operation have surgical wound it is small, caused by injury and pain it is small, post-operative recovery time is short, can more quickly restore, and amount of bleeding is few, art
In cause the risk of secondary injury low.
It is existing at present to hold that bar device use process is cumbersome, puts stick difficulty, the connecting rod of traditional material and the fusion rate of bone
Not high, fusion gap is easy to happen regression adjacent to the stage, and connecting rod and other fixed systems are easy to happen friction, lead to pain in the loins,
And the connecting rod of traditional material is to be bent in art according to clinical experience, there are camber is inconsistent and camber not meet lumbar vertebrae raw
Curvature is managed, local stress is formed and increases, lead to pain in the loins.
Polyether-ether-ketone (PEEK) material is a kind of special engineering plastics haveing excellent performance, it has high-intensitive and low dissolution
Property, the PEEK material body of rod and human body have good amalgamation, can reduce side effect reaction, but currently on the market not yet
Occur carrying out the case of Minimally Invasive Surgery using PEEK connecting rod, it is not matched with its to hold bar device yet.
Summary of the invention
The purpose of the present invention is to provide what a kind of cooperation PEEK connecting rod used to hold bar device, in the prior art to solve
Problem.
To achieve the above object, the invention provides the following technical scheme:
It is a kind of cooperation PEEK connecting rod use hold bar device, it includes sleeve, mandril and screw rod that this, which holds bar device, and sleeve is provided with
