Structural features and advantages
Size adaptability
The 4MM diameter and 180MM length make the nucleus pulposus forceps well adapted to the UBE surgical channel. The 4MM diameter ensures that it can smoothly pass through the working channel established by the UBE surgery and enter the relatively narrow space inside the spine for operation. The 180MM length provides sufficient operating distance for surgical operations, allowing doctors to perform operations in the appropriate position and avoid inconvenience caused by the instrument being too short.
Bullet-head blunt head design
The blunt head design of the bullet-head head is a highlight. This design allows the nucleus pulposus forceps to reduce damage to surrounding tissues when entering the tissue. In spinal surgery, there are many important nerves, blood vessels, and other structures around, and the blunt head can avoid accidental puncture or cutting of these sensitive tissues like sharp-headed instruments. For example, when entering the intervertebral disc space or approaching the spinal canal, the blunt head can play a role in buffering and protection.
45-degree upward bend angle
The 45-degree upward bend angle makes the nucleus pulposus forceps more operable during surgery. In the anatomical structure of the spine, the nucleus pulposus in many parts is relatively hidden or in an angled space. This upward bend angle can help the nucleus pulposus forceps reach the nucleus pulposus in these special positions more easily. For example, at the edge of the intervertebral disc space in the lumbar or cervical spine, or when dealing with some nuclei pulposus located in the curved part of the spine, the 45-degree upward bend angle allows the nucleus pulposus forceps to contact and grasp the nucleus pulposus more accurately.
Application scenarios in UBE surgery
Intervertebral disc nucleus pulposus removal
This is the most important application in UBE surgery for intervertebral disc herniation. After the location of the nucleus pulposus protrusion is observed through the endoscope, the nucleus pulposus forceps enter the intervertebral disc space through the working channel. The 45-degree upward bend angle and the bullet-shaped blunt head design help it to smoothly bypass other tissues and reach the location of the protruding nucleus pulposus. When grabbing the nucleus pulposus, due to its head shape and appropriate bending angle, the nucleus pulposus can be firmly grasped and removed from the intervertebral disc, thereby reducing the compression on the nerves and relieving the patient's pain, numbness, and other symptoms.
Cleaning the surgical area
It also has a good cleaning effect on free nucleus pulposus fragments, degenerated annulus fibrosus tissue, etc. in the surgical area. During the process of disc degeneration, the nucleus pulposus may be broken and free in the spinal canal. The nucleus pulposus forceps can use the special design and bending angle of its head to accurately locate and grab these fragments and diseased tissues, keep the surgical area clean and tidy, and prevent these fragments from causing further damage to the nerves and spinal cord.
Assisted tissue exploration and positioning
This nucleus pulposus forceps can also be used to assist tissue exploration. During surgery, doctors can use the shape and angle of its head to gently touch and explore tissues to help determine the exact location of the nucleus pulposus, especially in some complex anatomical structures or when the location of the nucleus pulposus is unclear. For example, when judging whether the nucleus pulposus is hidden behind other tissues or when determining the boundaries of the nucleus pulposus, its upward bending angle and blunt head design can play a good auxiliary role.
Operation precautions and skills
Operation precautions
Since the operation is performed under endoscopic visualization, be sure to ensure that the endoscopic field of view is clear before the operation. During the insertion and operation of the nucleus pulposus forceps, pay close attention to its relative position with important tissues such as nerves and blood vessels to prevent damage. At the same time, pay attention to the opening and closing strength of the nucleus pulposus forceps to avoid excessive force that causes tissue tearing or damage to the nucleus pulposus forceps.
Operation skills
Insert skills: According to the anatomical path observed by the endoscope and the structural characteristics of the surgical site, use the 45-degree upward bend angle and bullet-shaped blunt head design to insert the nucleus pulposus forceps at an appropriate angle and direction. Generally, it is necessary to insert slowly along the established working channel or natural anatomical gap to avoid forced insertion and damage to surrounding tissues.
Grasping skills: When grasping the nucleus pulposus, first gently bring the nucleus pulposus forceps close to the target nucleus pulposus, then slowly close the forceps, and use the shape and angle of the head to firmly grasp the nucleus pulposus. According to the size and texture of the nucleus pulposus, adjust the grasping force appropriately, and then remove the nucleus pulposus smoothly. During the operation, the real-time observation of the endoscope should be combined to flexibly adjust the position and operation method of the nucleus pulposus forceps to achieve the best surgical effect.
