Description
Technical Field
The invention relates to the field of medical instruments, in particular to an outer support needle way port negative pressure suction sealing device and a using method thereof.
Background
At present, the prevention means for the infection of the needle channel of the external fixed stent mainly comprises the needle channel nursing. The method comprises softening crust of needle channel with normal saline, massaging, applying chemical agent such as povidone iodine or chlorhexidine for disinfection, winding and fixing needle with dry yarn, and covering and protecting needle channel. The frequency of needle track care is reported in different documents to be different from twice a day to once a week, and needs to be specifically adjusted according to the condition of the needle track of a patient. However, since each external fixing frame usually has a large number of fixing needles, needle path nursing is a time-consuming and labor-consuming task, and a lot of time is needed.
Other studies have attempted to reduce the infection rate by modifying the materials and surface processes of the external fixation stent fixation needles. For example, researchers have applied a bactericidal sol-gel film with a thickness of microns to the surface of a stationary needle. Or a hydroxyapatite coating containing antibiotics is added on the surface of the needle. Still other studies have been directed to preventing needle tract infection by modifying the surface of the fixation needle to promote osseointegration at the bone-needle interface after insertion.
1. Although the needle path nursing technology which is commonly used at present is simpler theoretically, a certain skill is provided when the sliver is wound, the thickness of the sliver needs to be properly adjusted according to the distance from the needle clip to the surface of the skin, if the sliver is not tight enough during winding, the sliver can be loosened and scattered, the protection effect of covering the needle path cannot be achieved, and if the sliver is too tight, the skin around the needle path can be pressed to generate pressure sores or even necrosis. Secondly, because the outer fixed bolster needs many fixed needles to fix in different planes, different angles, just can obtain sufficient stability, therefore the needle is said to nurse and is a work that wastes time and energy, needs to consume a large amount of manpowers. The most important point is that no matter how the needle channel is nursed, the bones and soft tissues in the needle channel are always communicated with the outside. According to the report of the literature, the most common pathogenic bacteria of needle tract infection are body resident flora such as staphylococcus aureus, and the importance of needle tract exposure to infection occurrence is also described. This is particularly true when the fixation site is the thigh and a long time is required for external fixation of the stent. The muscles are abundant in the thighs and cannot be in a static state for a long time when being fixed. When the muscle contracts, the muscle fiber around the fixing needle is cut with the fixing needle, and the cut and damaged muscle fiber generates a large amount of seepage liquid, and the seepage liquid rich in protein is an ideal culture medium for breeding bacteria. Bacteria entering through the needle port can grow in large quantities as nutrients, causing infection that is difficult to control. When the external fixing bracket needs to be fixed for a long time, the fixing needle may be loosened due to repeated stress action, repeated micro-motion between the fixing needle and the bone at the needle channel can stimulate local inflammatory reaction, a large amount of inflammatory exudation can be caused, and bacteria breeding is facilitated. Therefore, the hidden danger of needle tract infection exists at any time as long as the needle tract opening is in an exposed state.
2. The surface of the fixing needle is modified, so that a coating which is beneficial to integration of a bone and a metal interface is added, or a substance which is beneficial to sterilization is added, and the infection resistance is also facilitated. However, no matter how modified or modified, the fact that the bone at the needle passage is fixed is not improved, and the way for bacteria to enter the needle passage is still open, and whether the infection is caused depends on the general and local resistance of the patient.
3. Removal of the fixation needle may be considered when a definite needle track infection has occurred, particularly when the fixation needle has become loose, provided that the needle may be repositioned elsewhere. The configuration of the external fixation frame and the anatomical portion of the limb do not necessarily have excess space for re-needling. And the needle is replaced, the operation needs to be performed again, and the patient suffers additional pain. If the infection affects the entire bone segment, repositioning the needle may not solve the problem. If the fixing needle is simply pulled out, the stability of the fixing of the outer fixing bracket can be influenced.
