UBE surgical tool - Grading expander

The process and significance of gradual expansion of soft tissues with an expander during UBE surgery
In minimally invasive spinal surgery, the UBE (Unilateral Biportal Endoscopy) technique has gradually received attention. Among them, the gradual expansion of soft tissue by the expander in UBE surgery is an important link.
I. Introduction to UBE Surgery
UBE surgery is a new type of minimally invasive spinal surgery technique. It achieves the treatment of spinal lesions by establishing two channels: the observation channel and the operation channel. This technique has the advantages of small trauma, quick recovery and clear field of vision, and has gradually become a research hotspot in the field of spinal surgery.
Ii. The Function of the Stepwise Expander
Creating surgical space: In UBE surgery, the main function of the step-up expander is to gradually expand the soft tissue, creating sufficient space for the entry of surgical instruments. The diameter of the expander starts from 5MM and gradually increases, successively expanding to 7MM, 9MM, 11MM, 13MM, and 15MM. It can effectively separate the surrounding soft tissues and avoid damaging important structures such as nerves and blood vessels.
Reduce tissue damage: Gradual expansion enables soft tissues to gradually adapt to the pressure of expansion, reducing tissue tearing and bleeding caused by excessive expansion at one time. Compared with traditional open surgery, the use of stepwise expanders in UBE surgery can significantly reduce the degree of damage to the surrounding tissues caused by the surgery, which is conducive to the postoperative recovery of patients. three
Be careful when expanding
When using a step-by-step expander for soft tissue expansion, it is necessary to master the correct operation skills. First of all, make sure the expander is inserted in the correct direction to avoid damaging the surrounding nerves and blood vessels. Secondly, during the expansion process, the force applied should be slow and even to avoid excessive force causing tissue tearing.
Observe the patient's response: During the dilation process, closely monitor the patient's vital signs and reactions. If the patient experiences abnormal conditions such as increased pain, decreased blood pressure, or accelerated heart rate, immediately stop the dilation and take corresponding treatment measures. Prevention
Infection: As the expander needs to be inserted into human tissue, strict aseptic operation principles must be followed during operation to prevent infection. The expander must be strictly disinfected before use, and the surgical area must be kept clean during the operation. 4
Advantages and disadvantages of step-by-step expanders
Advantages
Minimal trauma: The step-by-step expander can complete the expansion of soft tissues with minimal trauma, reducing the damage to the patient's body caused by surgery.
Fast recovery: Due to the small trauma, patients recover faster after the operation, which can shorten the hospital stay and reduce medical expenses.
Flexible operation: The step-by-step expander can be expanded to different degrees according to the surgical needs, adapting to various surgical conditions.
Disadvantage
High operational difficulty: Step-by-step expansion requires certain skills and experience, which may pose a certain operational difficulty for beginners.
Possible complications: Although step-by-step expansion can reduce tissue damage, complications such as bleeding, infection, and nerve damage may still occur during the operation.
V. Future Development Trends
With the continuous advancement of technology, the application of step-by-step expanders in UBE surgery will be continuously improved. In the future, more intelligent and automated expanders may emerge, which can automatically adjust the expansion degree according to the surgical needs, enhancing the safety and accuracy of the surgery. Meanwhile, with the development of materials science, the materials of expanders will also be continuously improved to make them lighter, more durable and more biocompatible.
In conclusion, the stepwise expander plays a crucial role in the expansion of soft tissues during UBE surgery. Through correct operation and precautions, the advantages of the stepwise expander can be fully exploited, surgical complications can be reduced, and the success rate of surgery and patient satisfaction can be improved.
