UBE (Unilateral Biportal Endoscopy) is a unilateral dual-channel endoscopic technique. UBE instruments mainly include the following:

1. Endoscope: used to observe the surgical area and provide a clear field of view.

2. Operating instruments: such as graspers, scissors, and dissectors, used for tissue separation, resection, and other operations.

3. Radiofrequency blade: can be used to stop bleeding and ablate tissue.

4. Perfusion system: used to continuously flush the surgical area to maintain a clear field of view.

UBE technology has the advantages of less trauma, faster recovery, and clear field of view, and has been increasingly widely used in fields such as spinal surgery.

The main differences between UBE instruments and interlaminar foraminal endoscopy technology are as follows:

1. Surgical approach

- UBE instruments: use a unilateral dual-channel approach, one channel is an observation channel, where an endoscope is placed; the other channel is an operating channel, where a variety of operating instruments can be placed. This approach allows a wider surgical field of view and a relatively large operating space.

- Foraminal endoscopic technique: enter through a single channel such as the intervertebral foramen or interlaminar space, the surgical instruments and endoscope are operated in the same channel, and the operating space is relatively small.

II. Field of view and operating space

- UBE instrument: Because there are two independent channels, the endoscope and the operating instrument do not interfere with each other, and the field of view is clearer and more three-dimensional. The operating space is large, and larger instruments can be used, which is more conducive to the treatment of complex lesions.

- Foraminal endoscopic technique: The field of view is relatively limited, the operating space is small, and the technical requirements for the surgeon are high. However, for some simple cases, the operation can also be completed effectively.

III. Indications

- UBE instrument: It is suitable for a variety of spinal diseases, such as lumbar disc herniation, lumbar spinal stenosis, cervical spondylosis, etc., especially for complex spinal stenosis cases. It can perform more extensive decompression and lesion removal.

- Foraminal endoscopic technique: It is mainly suitable for relatively simple lesions such as simple lumbar disc herniation. For complex conditions such as severe spinal stenosis, it may be more difficult to handle.

4. Learning curve

- UBE instrument: The learning curve is relatively gentle. Although it is necessary to master the operation skills of bilateral channels, it is relatively easy to use due to the large operating space.

- Transforaminal endoscopic technology: The learning curve is steeper. It requires high hand-eye coordination and spatial sense of the operator, and it takes a long time of practice and experience accumulation to master it.
