Description
Technical Field
The application relates to the technical field of medical equipment, in particular to a negative pressure drainage tube power transmission device.
Background
Closed drainage (of cavities such as thoracic cavity, abdominal cavity and perianal local pyogenic cavity) is a common surgical operation. It is used for treating various kinds of lacuna, hydrops, hematocele, purulence and pneumothorax. When in use, a negative pressure aspirator is adopted to generate certain negative pressure, and the negative pressure aspirator acts on the focus lacuna through the drainage tube to suck various liquids, gases and the like in the lacuna, thereby being beneficial to the healing of focus. The current research proves that the therapy can accelerate blood circulation in the lacuna, obviously promote the entry of new blood vessels, stimulate the growth of granulation tissues, fully drain, relieve edema, reduce pollution, inhibit bacterial growth, directly accelerate wound healing or create conditions for surgical repair, and is a pure physical therapy which is efficient, simple and economic and promotes wound healing.
However, in order to smoothly guide pus, blood and liquid accumulated in human tissues or body cavities to the outside of the body, the auxiliary part of the negative pressure drainage tube is often sutured on the skin surface of the human body when the negative pressure drainage tube is guided into the body cavity. Of course, this can effectively prevent the drainage tube from slipping, dislocating or shifting. However, once a little longer (about 5-7 days), the pus, blood, fluid, etc. in the body cavity may block the entrance of the drainage tube. Especially when the disease is relieved, new granulation tissue (commonly called new meat) grows into the drainage tube along the pressure gradient difference. At this time, the drainage tube can only be forcibly removed (the new granulation tissue, new blood vessel, fibroblast tissue and the like on the inner side and the outer side of the drainage tube are forcibly separated), and the secondary injury to the patient is necessarily caused, so that the pain of the patient is increased. Clinically, sometimes even a secondary operation has to be performed to remove the negative pressure drainage tube. Moreover, the current negative pressure drainage tube often has the problems of unsmooth drainage and infection of a drainage cavity. The former mostly adsorbs excessive cavity wall soft tissues due to the side holes of the negative pressure drainage tube. The situation is caused by the pressure gradient difference formed by negative pressure drainage, and the current negative pressure drainage tube cannot solve the problem; the problem of infection of the drainage cavity is often related to insufficient drainage and incision pollution. These problems are all to be solved.
In the negative pressure drainage tube 201710680574.1 of the inventor, a power device adopts spring transmission, but the spring transmission has low stability and inaccurate adjustment in the actual process, a certain risk exists, and the transmission in the power device can not be used for adjusting and steering.
