Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a suction device for spinal surgery. Background Technique

[0002] The spine is the pillar of the body, located in the middle of the back, connected to the skull at the upper end and reaching the tip of the coccyx at the lower end. The spine is divided into five segments: cervical, thoracic, lumbar, sacral and caudal. The upper part is long and movable, like a bracket, hanging the chest wall and abdominal wall; the lower part is short and relatively fixed. The weight and shock of the body are transmitted to the lower limbs through it. The spine is composed of vertebrae and intervertebral discs, and is a quite flexible and movable structure. In surgical operations, doctors usually use a suction device, and the function of the suction device is to suck out the bleeding, exudate, pus, and the contents of thoracic organs during the operation.

[0003] However, most of the existing suction devices have fixed length specifications, resulting in no telescopic function, and unable to meet the doctor's need to adjust the length of the suction device during the operation, which easily leads to incomplete suction of bleeding and exudate during the operation, making the surrounding area of the operation unclear and increasing the risk of surgical infection; and when the suction force disappears, the residual liquid will remain in the suction tube, which is not convenient to clean. Therefore, the utility model provides a suction device for spinal surgery to solve the problems raised in the above background technique. Content of the Utility Model
