UBE surgical tools-Graduate dilator

The process and significance of the expansion of soft tissue by the step-by-step dilator in UBE surgery
In minimally invasive spinal surgery, UBE (Unilateral Biportal Endoscopy) technology has gradually attracted attention. Among them, the expansion of soft tissue by the step-by-step dilator in UBE surgery is an important link.
I. Introduction to UBE surgery
UBE surgery is a new type of minimally invasive spinal surgery technology. It achieves the treatment of spinal lesions by establishing two channels, an observation channel and an operation channel. This technology has the advantages of small trauma, fast recovery, and clear vision, and has gradually become a research hotspot in the field of spinal surgery.
II. The role of the step-by-step dilator
Creating surgical space: In UBE surgery, the main role of the step-by-step dilator is to gradually expand the soft tissue and create enough space for the entry of surgical instruments. Starting from 5MM, the diameter of the dilator is gradually increased, and it is expanded to 7MM, 9MM, 11MM, 13MM and 15MM in turn, which can effectively separate the surrounding soft tissue and avoid damage to important structures such as nerves and blood vessels.
Reduce tissue damage: Step-by-step expansion can gradually adapt the soft tissue to the pressure of expansion, reducing tissue tearing and bleeding caused by one-time excessive expansion. Compared with traditional open surgery, the use of step-by-step expanders in UBE surgery can significantly reduce the degree of damage to surrounding tissues caused by surgery, which is beneficial to the patient's postoperative recovery.
III. Precautions during expansion
Operation skills: When using step-by-step expanders for soft tissue expansion, you need to master the correct operation skills. First, make sure that the expansion device is inserted in the correct direction to avoid damaging the surrounding nerves and blood vessels. Secondly, apply force slowly and evenly during the expansion process to avoid excessive force that causes tissue tearing.
Observe the patient's reaction: During the expansion process, closely observe the patient's vital signs and reactions. If the patient has abnormal conditions such as increased pain, decreased blood pressure, and increased heart rate, the expansion should be stopped immediately and appropriate treatment measures should be taken.
Prevent infection: Since the expander needs to be inserted into human tissue, the aseptic operation principle must be strictly followed during the 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 dilators
Advantages:
Less trauma: The step-by-step dilator can complete the expansion of soft tissue with less trauma, reducing the damage of surgery to the patient's body.
Fast recovery: Due to the small trauma, the patient's postoperative recovery speed is faster, which can shorten the hospitalization time and reduce medical expenses.
Flexible operation: The step-by-step dilator can be expanded to different degrees according to the needs of the operation and adapt to different surgical situations.
Disadvantages:
Difficulty in operation: Step-by-step expansion requires certain skills and experience, and there may be certain operational difficulties 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 dilators in UBE surgery will continue to improve. In the future, there may be more intelligent and automated dilators that can automatically adjust the degree of expansion according to surgical needs to improve the safety and accuracy of the operation. At the same time, with the development of material science, the material of the dilator will continue to improve, making it lighter, more durable, and more biocompatible.
In conclusion, the step-by-step expander plays a vital role in the expansion of soft tissue in UBE surgery. Through correct operation and precautions, the advantages of the step-by-step expander can be fully utilized to reduce surgical complications, improve the success rate of surgery and patient satisfaction.
