Structural features and advantages
Multiple sizes and special shape designs
Provide multiple diameters from 1MM to 5MM to meet the needs of UBE surgery from delicate parts to larger areas. The 2MM and 3MM upward curved designs take into account the physiological curvature of the spine, making it easier to handle special locations such as the edge of the intervertebral disc space and the side wall of the spinal canal. This diverse design allows surgeons to choose the most appropriate tool for operation according to specific surgical scenarios, such as cervical or lumbar spine surgery, different degrees of bone hyperplasia, or soft tissue lesions.
Excellent bone biting and soft tissue shearing performance
Its excellent bone-biting performance and soft tissue shearing are key advantages. In UBE surgery, bone biting can accurately remove bone from the lamina, articular processes, and other parts, creating conditions for operations such as spinal canal decompression or spinal fusion. For soft tissue, it can effectively shear adhesions of ligaments, scar tissue, etc., which helps to clear the surgical field and reduce nerve compression.
Anti-bone carding, human mechanics, and specific gravity ratio design
The design that prevents bone from getting stuck in the tool slot ensures the smoothness of the operation. The ergonomically designed handle allows the doctor to hold it comfortably, with fingers placed naturally to reduce hand fatigue. The specific gravity ratio design makes the operation more hand-feeling and helps to accurately control the bite force and shearing direction, which is crucial for delicate spinal surgery.
Special connection design
The design of the slide pin connection push rod makes the opening and closing of the forceps stable and accurate. When biting bones and shearing, it can ensure accurate alignment of the blade and proper pressure transmission, improving the safety and effectiveness of the operation.
Surface treatment advantages
The desalination process and DLC (diamond-like carbon) surface treatment are used. The DLC coating has good hydrophilicity, which allows liquids (such as saline and other flushing fluids) to spread better on the surface of the forceps during surgery, reducing liquid residue and droplet formation. The increase in hydrophilicity also helps the operation of surgical instruments in a wet environment. For example, when flushing the surgical area, the flushing fluid on the surface of the forceps can flow faster to keep the field of vision clear.
Anti-adhesion is another important advantage. After biting bones or shearing soft tissues, bone fragments, and tissue residues tend to adhere to the surface of the instrument, affecting subsequent operations. The DLC surface-treated pliers can effectively reduce this adhesion phenomenon and ensure the accuracy and efficiency of each bone-biting or shearing operation. For example, when biting off multiple bone fragments continuously, the next bone-biting action will not be affected by the adhesion of the previous bone fragments, and the bone fragments or tissue residues will not be accidentally brought to other surgical sites.
Application scenarios in UBE surgery
Comprehensive application in spinal canal decompression surgery
In the UBE surgical treatment of spinal stenosis, it can be used to bite off structures such as lamina and yellow ligament to expand the volume of the spinal canal. Pliers of different sizes have different uses for different degrees and locations of bone hyperplasia and soft tissue compression. For example, for cervical spinal canal stenosis, 1MM-3MM pliers may be used to bite off the bone hyperplasia of the lamina, and 2MM or 3MM upward curved pliers may be used to deal with the compression of the side wall of the spinal canal; in the case of lumbar spinal canal stenosis, 3MM-5MM pliers are selected for operation according to the actual situation. Its anti-adhesion property can maintain the good performance of the tool in operations such as continuous biting off the lamina and cleaning the yellow ligament. Its hydrophilicity helps to maintain a clear field of vision during the flushing process, making it easier to observe the decompression effect.
Effective assistance for spinal fusion surgery
In spinal fusion surgery, when dealing with the facet joint, its bone-biting performance is used to bite off part of the facet joint to create a suitable space for the placement of the fusion device. In terms of cleaning the soft tissue in the surgical area, the surgical area is ensured to be clean and tidy by shearing scar tissue, fat tissue, etc. The surface-treated pliers can prevent bone fragments from adhering during the biting off of the facet bone and improve the operation efficiency; the hydrophilicity is conducive to the flushing fluid to take away the broken bones and tissue residues when flushing the surgical area, providing a guarantee for the smooth progress of the fusion surgery.
Delicate operation in spinal tumor surgery
In spinal tumor surgery, for the bone and soft tissue invaded by the tumor, the pliers of appropriate size are selected according to the size and location of the tumor for bone biting and soft tissue removal. For example, for smaller tumors in the vertebral body, 1MM-3MM pliers can be used for delicate operations to remove tumor tissue while retaining normal tissue. In this delicate operation, the DLC surface-treated forceps can prevent tumor tissue fragments from adhering, which will affect the subsequent judgment and operation of normal tissues. The hydrophilicity helps to better observe the surgical site during the flushing process, creating favorable conditions for subsequent treatment or reconstruction surgery.
Operation precautions and skills
Operation precautions
Since UBE surgery is performed under endoscopic visualization, it is necessary to ensure that the endoscopic field of view is clear and accurately judge the relationship between the forceps and the surrounding tissues. During bone biting and shearing, special attention should be paid to avoid damaging important tissues such as nerves and blood vessels, because the forceps have strong bite force and improper operation can easily cause serious damage. At the same time, pay attention to whether there are abnormal adhesions on the surface of the tool that affect the operation. Although there is an anti-adhesion design, it is still necessary to pay attention.
Operation skills
Bone biting skills: Choose the appropriate size of forceps according to the anatomical path and bone conditions observed by the endoscope. When biting bones, place the blade of the forceps accurately on the bone part that needs to be bitten off, and use the handle designed by human mechanics to apply the bite force steadily. For hard bones, use multiple small bites to avoid excessive force.
Tips for soft tissue shearing: When handling soft tissue, place the blade of the forceps lightly against the target tissue and adjust the shearing angle. Adjust the opening and closing force appropriately according to the toughness and thickness of the soft tissue. For tightly adhered soft tissue, try to separate it with the tip of the forceps first, then shear it. During the operation, combine the real-time observation of the endoscope and flexibly adjust the position of the forceps and the operation method to achieve the best surgical effect.
