Description

Medical linkage flushing device

Technical Field

The invention relates to the field of medical instruments, in particular to medical linkage flushing equipment.

Background

During the surgical operation, the flushing operation is often needed, and the flushing operation mainly has four aspects: 1. the secretion polluted by the surgical cavity is washed clean by the washing water flow, so that the occurrence of postoperative inflammation and infection is reduced, and the clarity of the surgical field is ensured; 2. the temperature of some power instruments and tissues acted by the power instruments is reduced by flushing water flow, so that the thermal damage of the tissues is reduced, and the power instruments and the tissues are subjected to the temperature reduction by the flushing water flow, such as surgical electric drills, swinging saws, ultrasonic osteotomes, bipolar electric coagulators and the like; 3. the medium for providing action by using flowing water, such as a low-temperature plasma cutter head and the like; 4. under the technical condition of endoscopic surgery, after the lens is polluted by blood, the operative field is not clear, the lens can be clear by timely cleaning the lens, and the accuracy and the safety of the operation are ensured. With the development of surgical techniques, the requirements for intraoperative irrigation are increasing, such as response time of the irrigation system, pressure regulation, coordination with other electrically powered devices, and the like. Peristaltic pumps are a common solution, but when the water flow is required to be very small, the pulse of the peristaltic pump often cannot obtain a stable and continuous water flow; in addition, at present, peristaltic pumps are required to be integrated with corresponding electric equipment, such as electric drills, electrocoagulation, low-temperature plasma and the like, for power supply control, and the electric equipment which is used in a large amount in hospitals at present does not have the integrated peristaltic pumps. The special silica gel pump pipe required by the peristaltic pump obviously increases the use cost of consumables, and the peristaltic pump is very difficult to popularize and apply according to the current national charging policy.
