Device for continuous constant-temperature humidification in craniocerebral surgery

Abstract

The invention relates to the technical field of humidifying devices, in particular to a device for continuous constant-temperature humidification in craniocerebral surgery. The device comprises an elastic liquid bottle, a flow guide flexible tube and a constant-temperature adjustment device. The flow guide flexible tube is communicated with the elastic liquid bottle, and the tail section of the flow guide flexible tube is provided with a plurality of moistening holes. The constant-temperature adjustment device comprises an outer shell, an airtight water container, heating wires and a constant-temperature control component in electrical connection with the heating wires, and each of the upper end and the lower end of the water container is provided with a flow guide hole. The constant-temperature adjustment device comprises two T-shaped soft rubber sleeves, the middle portion of the flow guide flexible tube penetrates the water container through the two flow guide holes, and the T-shaped soft rubber sleeves internally sleeve the flow guide holes and externally sleeve the flow guide flexible tube to guarantee constant airtightness of the flow guide holes. The device is capable of replacing a mode of manually moistening brain tissues outside a surgical area and capable of continuously moistening the brain tissues outside the surgical area by surgical cotton, and brain tissue losscaused by personnel negligence or surgical cotton adhesion can be avoided.

Description

technical field [0001] The invention relates to the technical field of humidification devices, in particular to a continuous constant temperature humidification device for craniocerebral surgery. Background technique [0002] Brain tissue is an extremely water-rich tissue. We need to keep the brain tissue in the surgical field in a moist state for a long time during normal operations to prevent damage to brain tissue and spasm of cerebral blood vessels, thereby reducing craniotomy. In addition, we usually use moist brain cotton to protect the brain tissue except the main surgical field. However, the general brain surgery takes a long time, so if the moisture is not enough during the operation, there will often be serious adhesion between the brain tissue and the brain cotton, and the peeling of the brain cotton at the end of the operation will cause certain damage to the brain. When operating under a microscope, the brain tissue outside the field of view under the microscop...

AI Technical Summary

Problems solved by technology

It has the following disadvantages 1. During the operation, the operator and assistants tend to focus on the main parts of the operation, while ignoring the protection of the brain tissue in the surrounding non-operative area. 2. Impact-type flushing and humidification will cause damage to the brain tissue and blood vessels A certain amount of pressure may even cause adverse reactions, stimulation or even damage. 3. The amount of flushing water is not well controlled, which may cause: ① Insufficient moistening can not achieve the moistening effect ② Excessive flushing causes local water accumulation that affects surgical exposure and even affects the operation of the surgeon 4. Conventional surgery Although the physiological saline used in the flushing water is heated, it cools down quickly at the surgically controlled room temperature (21-25°C)

Accidental flushing of liquid into the operation area can easily cause brain damage and vasospasm 5. Manual flushing increases the workload of the operator or assistants, and the flushing process will affect the continuity of the operation of the operator
