Percutaneous vertebral plate drilling precise depth-limiting trepan set for minimally invasive spine surgery

Abstract

The invention discloses a percutaneous vertebral plate drilling precise depth-limiting trepan set for minimally invasive spine surgery, and belongs to the field of medical instruments. The percutaneous vertebral plate drilling precise depth-limiting trepan set comprises a depth-limiting trepan, a limiting soft tissue opening sleeve, a depth-limiting grinding disc, limiting buckles and a saw ring,wherein the depth-limiting trepan is sleeved with the limiting soft tissue opening sleeve; the limiting soft tissue opening sleeve is detachably connected with the depth-limiting trepan; the depth-limiting grinding disc is arranged in the depth-limiting trepan and detachably connected with the depth-limiting trepan; the top end of the depth-limiting trepan and the top end of the depth-limiting grinding disc are sleeved with the limiting buckles correspondingly; and the saw ring is arranged on the bottom side of the depth-limiting trepan. A channel is opened for further operation in the spinalcanal, the percutaneous vertebral plate drilling precise depth-limiting trepan set is precise, safe and efficient, the surgical mode that in the prior art, a rongeur bites a vertebral plate or a spherical high-speed grinding drill bit is used for grinding the vertebral plate under X-ray perspective monitoring is changed, excessive resection injuries to the vertebral plate and more radiation exposure of doctors and patients are avoided, and interference and injuries to adjacent peripheral soft tissue and the neural structure in the spinal canal are reduced.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a percutaneous laminar drilling precision depth-limiting ring saw set for minimally invasive spinal surgery. Background technique [0002] Minimally invasive surgery is the mainstream direction of clinical medicine development, and percutaneous minimally invasive technology is an important way to achieve minimally invasive spinal surgery. Accurate, targeted circumcision and grinding of the spinal lamina through the skin and soft tissue from the posterior approach of the spine to achieve regular resection of the target site of the lamina and drilling to establish a bone channel or partial resection to expand the interlaminar space to establish Surgical approach is the premise of achieving minimally invasive spinal lesion resection. Compared with traditional open laminectomy techniques, it has significant minimally invasive advantages such as less trauma, lower risk, higher effic...

Problems solved by technology

It has changed the previous traditional operation, where the spherical high-speed grinding drill bit is used to grind the lamina under X-ray fluoroscopy monitoring. In order to avoid the spherical grinding drill bit protruding into the spinal canal and damaging the nerves, more radiation exposure is required to monitor its position, and the spherical grinding drill bit is harmful to the vertebral body. After the plate is removed, there are many irregular channels, which seriously damage the tissue structure that maintains the stability of the spine, cause large iatrogenic trauma, and the operation efficiency is low. , due to excessive damage to the soft tissue and bony structures leading to spinal instability, it is often necessary to add internal fixation devices to rebuild the stability of the spine, resulting in the loss of motion segments and high surgical costs.
