Description

Technical Field

[0001] The utility model belongs to the technical field of surgical auxiliary devices, and in particular relates to a water supply device for assisting UBE surgery. Background Art

[0002] The current unilateral biportal endoscopy (UBE) technology originated in Argentina and developed in South Korea. In recent years, it has been rapidly developed and popularized in China. The unilateral biportal endoscopy (UBE) technology uses a camera system and continuous fluid irrigation in the body to provide a clearer surgical field, reduce surgical trauma, and accelerate patient recovery. It is increasingly widely used in spinal surgery. With the development of minimally invasive spinal surgery, unilateral biportal endoscopy (UBE) technology has gradually been accepted and promoted as an emerging minimally invasive technology. The unilateral biportal endoscopy (UBE) technology establishes two working channels for observation and operation percutaneously, and conventional surgical instruments are used during the operation, which greatly expands the surgical field of view and improves work efficiency.

[0003] During UBE surgery, it is necessary to maintain appropriate perfusion pressure. First of all, the water supply device must be highly designed to maintain good water flow from the 3L saline bag, so as to achieve the effect of using water pressure to stop bleeding during surgery, further reduce surgical blood loss, and make the surgery more minimally invasive and precise. At the same time, it can ensure a clear surgical field, make surgical operations safer, and reduce the difficulty of surgical operations due to unclear surgical fields, leading to other possible complications such as damage to the dura mater and nerve roots. Appropriate water pressure helps the surgeon to separate the dura mater and the yellow ligament during surgery, further reducing the probability of damaging the dura mater and nerve roots during surgery. UBE technology uses a large amount of saline for continuous flushing during surgery, which greatly reduces the probability of infection.

[0004] There are two types of existing UBE water supply devices:

[0005] 1. Ordinary infusion stands are used as surgical water supply devices to assist in UBE surgery. However, ordinary infusion stands are too light and unstable, and their height cannot meet the requirements of UBE surgery for continuous liquid irrigation and hydrostatic pressure.

[0006] 2. Hanging rail infusion stand. Some hospitals use hanging rail infusion stands as surgical water supply devices. Since 3L of normal saline is usually used as flushing fluid during UBE surgery, the hanging rail infusion stand has insufficient load-bearing capacity and is easy to fall, posing a safety hazard.

[0007] Therefore, how to ensure that the water supply device is safe and stable while meeting the requirements of UBE surgery for continuous liquid irrigation liquid hydrostatic pressure is a technical problem that technical personnel in this field need to solve. Utility Model Content

[0008] In order to solve the problems that the existing water supply devices have poor stability, cannot meet the requirements of UBE surgery for continuous liquid irrigation liquid hydrostatic pressure and have potential safety hazards, the utility model provides a water supply device for auxiliary UBE surgery that can improve the safety factor of suspended flushing liquid and adjust the height of the water supply device to meet the requirements of UBE surgery for continuous liquid irrigation liquid hydrostatic pressure.
