UBE surgical tools-cervical-lumbar-thoracic half-sleeve

Structural features and advantages
Multiple sizes
The protective sleeves used in UBE surgery provide a variety of size options, such as 15MM×4MM, 15MM×8MM, and other different specifications. This diverse size design can adapt to different surgical scenarios and instrument requirements. Larger protective sleeves (such as 15MM×10MM) can accommodate larger surgical instruments or pass through multiple small instruments at the same time, which is convenient for improving surgical efficiency when multiple tools need to be used in coordination. Smaller protective sleeves (such as 10MM×4MM) are more suitable for use in areas with limited space and requiring delicate operations, which can reduce pressure on surrounding tissues.
The size design of the protective sleeve also takes into account the flexibility of instrument operation. For example, the size in the long axis direction (such as 15MM or 10MM) can be selected according to the depth of the surgical site and the length of the instrument to ensure that the instrument can pass through the sleeve smoothly to the surgical site; the size in the short axis direction (such as 4MM-10MM) determines the activity space of the instrument in the sleeve, and the appropriate activity space helps to accurately control the direction and operation angle of the instrument.
Application scenarios in UBE surgery
Instrument guidance and protection
During the entire UBE surgery, the protective sleeve plays a key role in guiding the instrument into the surgical site. Taking cervical spine UBE surgery as an example, when it is necessary to use instruments such as nucleus pulposus forceps or biting forceps to enter the intervertebral disc space or spinal canal, the protective sleeve can provide the correct entry path for the instrument. Protective sleeves of different sizes can be selected according to the size of the specific instrument. For example, for a 2.5MM nucleus pulposus forceps with a smaller diameter, a 10MM×4MM protective sleeve can well guide it into the surgical site, while preventing the instrument from deviating from the direction during entry and damaging the surrounding nerves and blood vessels.
The protective sleeve can also protect the surrounding tissue from damage by the instrument. In spinal surgery, there are important structures such as the spinal cord, nerve roots, and blood vessels around the surgical area. The protective sleeve plays the role of isolation and buffering when the instrument enters and exits. For example, in lumbar spine UBE surgery, when a larger cutting tool is used for laminectomy, a 15MM×10MM protective sleeve can prevent the blade of the instrument from accidentally scratching the surrounding tissue, ensuring the safety of the operation.
Multi-instrument collaborative operation scenario
In some complex UBE surgical scenarios, it may be necessary to use multiple instruments at the same time. For example, in spinal fusion surgery, it may be necessary to use grinding drills, implantation tools, etc. at the same time. At this time, larger protective sleeves (such as 15MM×8MM or 15MM×10MM) can play an advantage, allowing different instruments to pass through sequentially or simultaneously, making it convenient for doctors to flexibly switch instruments during surgery, perform operations such as bone grinding and fusion device implantation, and improve the fluency and efficiency of surgery.
Adapt to different surgical sites and depth requirements
Choose a protective sleeve of appropriate size according to whether the surgical site is cervical, lumbar, or thoracic, and the depth of the surgical operation. In cervical spine surgery, due to the relatively delicate anatomical structure of the cervical spine and the small surgical space, it may be more inclined to use a smaller protective sleeve (such as the 10MM series) to reduce pressure on surrounding tissues. In lumbar spine surgery, for some operations in deeper parts or when larger lesions need to be handled, a larger and longer protective sleeve (such as 15MM×10MM) may be more suitable to ensure that the instrument reaches the surgical site smoothly and performs effective operations.
Operation precautions and skills
Operation precautions
When selecting the size of the protective sleeve, it is necessary to make comprehensive considerations based on the size of the surgical instrument actually used, the anatomical structure of the surgical site, and the complexity of the surgical operation. Ensure that the selected protective sleeve size can meet the passage and operation requirements of the instrument, and will not cause unnecessary compression to the surrounding tissue due to being too large. When inserting the protective sleeve, be careful to avoid damaging the surrounding tissue, especially nerves and blood vessels. It can be inserted along the natural anatomical gap or pre-established channel under the guidance of an endoscope.
During the operation, pay attention to the fixed position of the protective sleeve. If the position of the protective sleeve is offset, it may affect the operation path of the instrument and increase the risk of the operation. At the same time, pay attention to whether there is tissue embedded in the protective sleeve or the instrument is stuck, and clean or adjust it in time to ensure the smooth progress of the operation.
Operation skills
Insertion skills: According to the anatomical path shown by the endoscope, insert the protective sleeve into the surgical site at a suitable angle and direction. In the early stage of insertion, you can use a thinner guide wire for guidance, and then slowly insert the protective sleeve along the guide wire. For longer protective sleeves, pay attention to controlling the insertion depth to avoid too deep or too shallow to affect the operation of the instrument.
Instrument passing skills: When inserting the instrument through the protective sleeve, make sure that the central axis of the instrument is basically consistent with the central axis of the protective sleeve to avoid friction or collision between the instrument and the inner wall of the sleeve. If you encounter difficulties in inserting the instrument, you can adjust the position of the protective sleeve appropriately or check whether the size of the instrument matches the sleeve. During the operation, flexibly replace protective sleeves of different sizes as needed to adapt to different stages of instrument operation.
