Multifunctional visible trepan for two-channel minimally invasive operation

Abstract

The invention discloses a multifunctional visible trepan for two-channel minimally invasive operation. The multifunctional visible trepan comprises a trepan body, a positioning device, a spring and an endoscope, wherein the trepan body is used in a percutaneous spinal operation; the positioning device is clamped in the trepan body and used for achieving a positioning effect; the spring is connected to the positioning device in a sleeving mode and located inside the trepan body; and the endoscope is located in the positioning device and used for enlarging the operation view field. The trepan can monitor the nerve position in real time and is prevented from cutting the nerve by mistake, when the trepan moves, the endoscope can follow up in time, the operation view field is enlarged, and tissue fluid at the affected part can be flushed and sucked in time.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, relates to a minimally invasive surgical tool, in particular to a multi-functional visible ring saw for dual-channel minimally invasive surgery. Background technique [0002] With the continuous development and innovation of spinal surgical instruments and surgical methods, minimally invasive spinal surgery (MISS) has become an important surgical concept in spinal surgery. Although traditional spinal fusion or non-fusion surgery has been widely used in the treatment of degenerative diseases such as intervertebral disc herniation or spinal stenosis, such traditional open surgery has the disadvantages of large surgical trauma, many intraoperative complications and long postoperative recovery time. Long and other disadvantages. How to achieve or approach the therapeutic effect of traditional open surgery while minimizing trauma to normal soft tissues is the main surgical goal and local ...

Problems solved by technology

[0005] In the prior art, the ring saw under the microscope is mostly used, and its disadvantage is that the operation channel of the endoscope limits the operation direction of the ring saw, and the position seen under the microscope is limited. When the ring saw is inserted, it needs to be positioned separately and the saw teeth are easy to damage the peripheral nerves; It is necessary to fix the working sleeve and the endoscope with one hand, and the other hand presses forward while rotating the trephine for bone grinding. When the trephine moves, the endoscope cannot follow up in time, causing the teeth of the trephine to detach from the endoscope. The field of view requires an additional adjustment of the positional relationship between the endoscope and the trephine
