Structural features and advantages
Size and shape
The design of 3MM diameter and 180MM length makes the nucleus pulposus grasping forceps have good passability and operation convenience in the UBE surgical channel. The smaller 3MM diameter can easily pass through the surgical channel, and the 180MM length ensures the operating range inside the spine. The straight design is convenient for operation in a relatively straight anatomical path, and the round head can effectively prevent damage to sensitive tissues such as nerves and blood vessels during insertion and movement, providing safety protection in complex spinal surgical environments.
Bowl mouth design
The bowl mouth shape increases the contact area with the nucleus pulposus tissue and can better fit the irregular shape of the nucleus pulposus. This design helps to grasp the nucleus pulposus more firmly, especially when dealing with soft and easily deformed nucleus pulposus tissue. The bowl mouth can wrap the nucleus pulposus like a "small container" to reduce the possibility of the nucleus pulposus slipping during the grasping process.
Shearing performance
Having shearing performance is an important feature of the nucleus pulposus forceps. During surgery, it can not only grasp the nucleus pulposus tissue, but also shear some adherent tissues or unnecessary tissue fibers. For example, when the nucleus pulposus tissue is tightly adhered to the surrounding annulus fibrosus or other tissues, this shearing property can help doctors cut off the adhesion part before grabbing the nucleus pulposus, making it easier to grab and remove the nucleus pulposus completely.
Application scenarios in UBE surgery
Removal of intervertebral disc nucleus pulposus
In UBE surgery for intervertebral disc herniation, the nucleus pulposus forceps play a key role. First, the nucleus pulposus protrusion position is determined by endoscopy, and then the nucleus pulposus forceps are passed through the working channel into the intervertebral disc space. The bowl-shaped design is used to wrap and grab the protruding nucleus pulposus. When the nucleus pulposus is adhered to the surrounding tissues, the shearing property is used to cut off the adhesion part, and the nucleus pulposus is smoothly removed from the intervertebral disc, reducing the compression on the nerves and relieving the patient's pain, numbness and other nerve compression symptoms.
Cleaning the surgical area
The nucleus pulposus forceps can effectively clean the free nucleus pulposus fragments, degenerated annulus fibrosus tissue, and possible inflammatory granulation tissue in the surgical area. The bowl-shaped design helps to accurately grasp the fragments, while the shearing performance can be used to handle larger tissue blocks or tissues that are adhered to each other, keep the surgical area clean, and prevent fragments or diseased tissues from causing further compression or damage to the nerves and spinal cord.
Tissue separation and repair assistance
During the operation, the shearing performance and bowl-shaped design can be used to assist in the separation of tissues. For example, when it is necessary to distinguish between normal tissue and diseased tissue, or when looking for the nucleus pulposus hidden behind other tissues, the tissue can be separated by gently shearing and poking. In addition, in some surgical scenarios of tissue repair, it can also help clean the edges of damaged tissues and create good conditions for tissue healing.
Operation precautions and tips
Operation precautions
Since the surgical operation depends on endoscopic visualization, it is important to ensure that the endoscopic field of view is clear so that the relationship between the nucleus pulposus forceps and the surrounding tissues can be accurately observed. During the insertion and operation process, always pay attention to avoid damaging important structures such as nerves and blood vessels. When using the shearing function, be careful to avoid accidentally cutting important tissues. At the same time, when opening and closing the nucleus pulposus forceps to grasp tissues, control the strength to prevent excessive force from causing tissue tearing or damage to the nucleus pulposus forceps.
Operation skills
Insertion skills: According to the anatomical path observed by the endoscope and the structural characteristics of the surgical site, insert the nucleus pulposus forceps at an appropriate angle and direction. Using the characteristics of the round head, slowly insert along the natural anatomical gap or the established working channel to avoid damage to the surrounding tissue caused by forced insertion.
Grasping and shearing skills: When grasping the nucleus pulposus tissue, first gently bring the nucleus pulposus forceps close to the target tissue, and then slowly close the forceps. Use the bowl-shaped design to allow the nucleus pulposus to fully enter the bowl-shaped mouth, and adjust the gripping force appropriately according to the size and texture of the nucleus pulposus. When shearing is required, the part of the tissue to be cut should be accurately placed in the shearing position of the forceps, and gently apply pressure to cut. During the operation, the position and operation method of the nucleus pulposus forceps should be flexibly adjusted in combination with real-time observation of the endoscope to achieve the best surgical effect.
