UBE surgical tools-UBE osteotome left curved

Structural features and advantages
Targeted left-bend design
The 5MM left-bend osteotome is bent toward the left side. This design is to better handle the bone structure at a specific position on the left side of the spine. In spinal surgery, this targeted bend can accurately reach the diseased bone on the left side of the spine without interfering with the normal tissue and anatomical structure on the right side. For example, when dealing with stenosis of the left intervertebral foramen of the lumbar spine, the left-bend osteotome can follow the left side contour of the spine and easily approach and handle the bone hyperplasia that causes stenosis without affecting the nerve roots and blood vessels on the right side.
Advantages of spatial adaptability
The left-bend shape makes the osteotome more operable in the limited space on the left side of the spine. In the cervical, thoracic and lumbar regions, the tissues and structures around the spine are complexly distributed, and the left-bend osteotome can use its curved part to cleverly avoid important tissues such as nerves and blood vessels on the left side, while effectively utilizing the surgical operation space on the left side. Compared with the straight osteotome, it can work at a narrower angle, such as in the left cervical lamina decompression surgery, it can better fit the physiological curve of the left side of the cervical spine and complete the bone removal in a limited space.
Application scenarios in UBE surgery
Applications in cervical spine surgery
Left-side cervical decompression surgery: In surgery for left-side cervical spinal stenosis or nerve root compression, the left-curved osteotome can be used to remove bone around the left cervical vertebral lamina and intervertebral foramen. After entering the left side of the cervical spine through the UBE surgical channel, the left-curved part of the osteotome can accurately fit the contour of the left side of the cervical spine and remove the bone hyperplasia that compresses the nerve root along the edge of the intervertebral foramen. For example, when symptoms of nerve root compression appear on the left side of the C4-C5 or C5-C6 cervical vertebrae, the left-curved osteotome can effectively expand the intervertebral foramen space, reduce compression on the left nerve root, and relieve the patient's pain, numbness and other symptoms on the left side of the upper limb.
Assisted cervical fusion surgery (left side): In the preparation stage of cervical fusion surgery, when it is necessary to deal with the bone of the left cervical vertebral endplate or facet joint, the left-curved osteotome can play an advantage. It can trim the left endplate of the vertebra along the lordotic curve of the left side of the cervical spine, or remove part of the bone of the left facet joint, creating suitable conditions for the implantation of the fusion device. For example, during anterior cervical fusion surgery, for intervertebral fusion on the left side of the cervical spine, the left-curved osteotome can help clean the cartilage tissue on the surface of the left vertebral endplate, so that the fusion device can better fit the endplate.
Lumbar Surgery Application
Left-side Lumbar Disc Surgery Assistance: In UBE surgery for lumbar disc herniation, if the protruding nucleus pulposus is located on the left side or there is bone hyperplasia on the edge of the left intervertebral disc that affects the surgical operation, the 5MM left-curved osteotome can be used for treatment. It can contact and chisel the hyperplastic bone along the side or front of the left side of the lumbar spine using the left-curved shape to create better conditions for the treatment of the intervertebral disc. For example, on the left side of the L4-L5 or L5-S1 lumbar segment, the osteotome can help clear the bone that affects the left surgical field, facilitating subsequent left nucleus pulposus removal and other operations.
Lumbar left canal decompression and fusion surgery: In decompression surgery and lumbar fusion surgery for lumbar spinal stenosis, the left-curved osteotome is a good tool for bone treatment of the left spinal canal and intervertebral foramen of the lumbar spine. It can adapt to the physiological lordosis of the left side of the lumbar spine, accurately remove the bone of the left spinal canal side wall, lamina and facet joint without damaging the left nerves and blood vessels, expand the volume of the left spinal canal, and create a suitable space for left nerve decompression or implantation of the left fusion device.
Thoracic Surgery Application
Auxiliary treatment of left intervertebral disc lesions in the thoracic spine: In surgery for thoracic disc herniation or degeneration, the left-curved osteotome can assist in the treatment of bone on the left edge of the thoracic vertebral body to better expose the left intervertebral disc space or remove bone hyperplasia that compresses the left nerve. Because the thoracic spine is protected by ribs and thorax, the surgical space is relatively narrow. The shape of the left-curved osteotome can help it operate accurately in a limited space and reduce damage to surrounding tissues.
Surgery for left thoracic fracture: In the surgical treatment of left thoracic fracture, osteotome can be used to reduce the left fracture fragment or remove the bone that affects the reduction of the left fracture. The left-curved design enables the osteotome to accurately process the bone along the left fracture line or the edge of the fracture fragment in the complex anatomical structure of the left side of the thoracic spine, creating conditions for the smooth reduction and fixation of the left fracture.
Operation precautions and skills
Operation precautions
Since the UBE operation is performed under endoscopic visualization, it is necessary to ensure that the endoscopic field of view is clear before the operation, and accurately judge the relationship between the left-curved osteotome and the surrounding tissues. Special attention should be paid to the position of important tissues such as nerves and blood vessels on the left side to avoid damaging them during the operation. During the insertion and operation of the osteotome, the insertion angle and percussion force of the osteotome should be reasonably controlled according to the anatomical characteristics of the left side of the spine. At the same time, attention should be paid to the cleaning and disinfection of the osteotome to avoid surgical infection due to instrument contamination.
Operation skills
Insertion skills: According to the anatomical path observed by the endoscope and the structural characteristics of the left side of the spine at the surgical site, the left-curved osteotome should be slowly inserted at an appropriate angle and direction. During the insertion process, use its 5MM diameter to carefully enter the surgical area along the natural anatomical gap on the left side of the spine or the established working channel to avoid forced insertion and damage to surrounding tissues. For example, in the left anterior approach surgery of the lumbar spine, when inserting the left curved osteotome, the curved part of the osteotome can be inserted along the lateral anterior gap on the left side of the lumbar spine, and then the direction can be adjusted to make it contact the target bone.
Bone chisel skills: When chiseling bones, place the cutting edge of the osteotome accurately on the left bone part to be processed, and use appropriate knocking force according to the hardness and thickness of the bone. For harder bones, you can use less force to knock multiple times; for softer bones, you should also pay attention to controlling the force to avoid excessive bone crushing. During the entire operation, the position and operation method of the left curved osteotome should be flexibly adjusted in combination with real-time observation of the endoscope to achieve the best surgical effect. For example, during left-side posterior spinal decompression surgery, when using a left-curved osteotome to remove bone from the edge of the left cervical vertebral lamina, the force and depth of the tapping should be carefully controlled based on the distance between the bone and the left nerve as seen under the endoscope to prevent damage to the spinal cord and left nerve roots.
