Structural features and advantages
Advantages of size diversity
4MM retractor: The 4MM spinal retractor has delicate characteristics and can play a role in the relatively narrow UBE surgical channel and delicate spinal anatomical structure. In cervical and thoracic spine surgery, especially when dealing with narrow areas such as the intervertebral foramen and spinal canal or performing some delicate nerve decompression operations, the 4MM retractor can provide sufficient retraction space without causing excessive tissue compression. For example, in cervical intervertebral foraminal decompression surgery, it can retract soft tissues to provide a better operating field for nerve decompression surgical instruments while avoiding damage to surrounding nerves and blood vessels.
10MM retractor: The 10MM retractor is more suitable for situations where a larger retraction space is required. In lumbar spine surgery or when dealing with a larger range of spinal lesions, such as lumbar spinal canal decompression, lumbar fusion surgery, etc., the 10MM retractor can effectively retract muscles, ligaments and other tissues to fully expose the surgical area. It can provide a wider field of view, making it easier for doctors to use various surgical instruments for operations, such as placing fusion devices and handling intervertebral discs.
Advantages of retraction function
Both sizes of retractors can retract the tissues around the spine stably and effectively. They are designed to maintain the retraction state during surgery, keeping the surgical field open and convenient for doctors to operate. By using the retractor properly, the retraction of tissues can be reduced, providing a clear and stable operating environment for surgery. For example, in spinal trauma surgery, the retractor can retract the soft tissues around the fracture, which is convenient for cleaning fracture fragments, resetting fracture fragments, and other operations.
Application scenarios in UBE surgery
Application of cervical spine surgery
Anterior cervical spine surgery: In anterior cervical discectomy and fusion surgery, the 4MM retractor can be used to retract the soft tissues in front of the vertebral body, such as the muscles and fascia next to the esophagus, trachea and other tissues, to provide a channel for surgical instruments to enter the intervertebral disc space. At the same time, it can keep the surgical field open and facilitate operation when dealing with bone hyperplasia at the edge of the cervical vertebral body or implanting an intervertebral fusion device. The 10MM retractor plays a role when it is necessary to treat multiple cervical segments at the same time or perform more complex anterior surgery, such as in the anterior cervical corpectomy surgery, fully retracting the tissue to provide sufficient operating space for the surgery.
Posterior cervical surgery: In the posterior cervical spinal canal decompression surgery, the 4MM retractor can be used to retract the soft tissue around the lamina to help expose the posterior wall of the spinal canal, facilitate the removal of the lamina, the treatment of the yellow ligament, and protect the spinal cord and nerve roots. The 10MM retractor can be used when a large range of posterior cervical decompression or posterior fusion surgery is required, such as in the posterior cervical multi-segment spinal canal decompression combined with lateral mass screw fixation and fusion surgery, effectively retracting the muscles and ligaments to create good conditions for surgical operations.
Lumbar surgery application
Lumbar disc surgery: In the UBE surgery for lumbar disc herniation, the 10MM retractor can retract the muscles and fascia of the waist to expose the intervertebral disc space. When performing operations such as nucleus pulposus removal and annulus fibrosus repair, keep the surgical area open to facilitate the operation of surgical instruments. The 4MM retractor can play a role in treating small lesions on the edge of the intervertebral disc or performing fine decompression on the nerve root, such as retracting the soft tissue around the intervertebral foramen in the nerve root decompression surgery under the intervertebral foramina endoscopic view to create space for nerve root decompression.
Lumbar spinal canal decompression and fusion surgery: In the decompression surgery and lumbar fusion surgery for lumbar spinal stenosis, the 10MM retractor is an indispensable tool. It can retract the muscles and ligaments around the spinal canal, fully expose the spinal canal and intervertebral foramen, facilitate the removal of hyperplastic bone, hypertrophic yellow ligament, and perform operations such as fusion device implantation. The 4MM retractor can assist in retracting some delicate areas during the operation, such as the soft tissue around the nerve root, to ensure the accuracy and safety of the operation.
Thoracic Surgery Application
Thoracic disc surgery: In the operation of thoracic disc herniation, the 4MM retractor can be used to retract the soft tissue between the thoracic vertebrae to provide space for the treatment of the intervertebral disc. The thoracic spine is protected by ribs and thorax, and the surgical space is relatively narrow. The fine size of the 4MM retractor can better adapt to this environment. The 10MM retractor is used when the thoracic intervertebral disc needs to be more widely exposed or when thoracic fusion surgery is performed, such as in anterior thoracic fusion surgery, to retract the tissue in the thorax to create conditions for surgery.
Thoracic fracture surgery: In thoracic fracture surgery, the retractor can retract the soft tissue around the fracture to facilitate observation of the fracture and reduction and fixation operations. The 4MM retractor can be used to retract the fine area around the fracture fragment, such as the soft tissue near the spinal cord, while the 10MM retractor is used to retract a larger range of muscles and ligaments to provide sufficient operating space for fracture surgery.
Operation precautions and skills
Operation precautions
Correctly select the size: According to the surgical site, type of surgery, and the range and fineness of the tissue to be retracted, correctly select a 4MM or 10MM retractor. In delicate operation areas or narrow anatomical spaces, such as the intervertebral foramen of the cervical spine, 4MM retractors are preferred; in surgeries that require a larger operating space, such as lumbar spinal canal decompression surgery, 10MM retractors may be more appropriate.
Avoid tissue damage: During the insertion and use of the retractor, care should be taken to avoid damaging nerves, blood vessels, and other important tissues. Through endoscopic observation, carefully place the retractor in the appropriate position to ensure that the blades of the retractor do not compress or cut tissue. Especially in areas rich in nerves and blood vessels around the spine, such as the spinal canal and near the intervertebral foramen, the operation should be particularly cautious.
Maintain retraction stability: During the operation, the retractor should be kept in a stable state. If the retractor is loose or its position changes, it may cause tissue retraction in the surgical area, affect the surgical operation, and may even damage the tissue. Therefore, ensure that the retractor's fixing device is firm and reliable.
Operation skills
Insertion skills: According to the anatomical path observed by the endoscope and the tissue distribution of the surgical site, slowly insert the retractor at an appropriate angle and direction. For the 4MM retractor, its fine size should be used to carefully enter the surgical area along the natural anatomical gap or the established working channel. For example, in anterior cervical spine surgery, when inserting the 4MM retractor, it can be inserted along the gap at the front edge of the vertebral body first, and then the direction can be adjusted to retract the tissue. For the 10MM retractor, pay attention to its larger size when inserting it. It may be necessary to perform some tissue separation before inserting the retractor to avoid tissue damage caused by forced insertion.
Retraction skills: When retracting tissue, gradually apply the retraction force according to the toughness of the tissue and the degree of retraction required. For tougher tissues, such as ligaments, the retraction force can be appropriately increased, but it is necessary to observe the reaction of the tissue to avoid excessive retraction and tissue tearing. At the same time, the position and retraction direction of the retractor should be adjusted in combination with real-time endoscopic observation to achieve the best retraction effect and provide a good field of view and space for surgical operations.
