Percutaneous lamina cutting and drilling precision limited depth suction cutting type trephine suit for minimally invasive spine surgery

Abstract

The invention discloses a percutaneous lamina cutting and drilling precision limited depth suction cutting type trephine suit for minimally invasive spine surgery, which belongs to the field of medical instruments. The percutaneous lamina cutting and drilling precision limited depth suction cutting type trephine suit includes a depth limited trephine, a limiting soft tissue distraction sleeve sleeving the bottom end of the depth limited trephine and detachably connected with the depth limited trephine, a limiting buckle sleeving the top of the depth limited trephine and slidably connected withthe depth limited trephine and a trephine ring arranged on the bottom side of the depth limited trephine, a negative pressure cover threadedly connected with the depth limited trephine is arranged atthe top end of the depth limited trephine, and a negative pressure absorption hole is formed in the negative pressure cover. Establishing a bone channel on a spine lamina through minimally invasive targeting and precise circular cutting and drilling is achieved, the damage is reduced, and the efficiency is improved; and a previous open surgical rongeur forceps to cut the spine lamina is changed,the iatrogenic destruction of the lamina is reduced, the operation is convenient, the device is time-saving and scientific, the safety is high, and the interference and damage to nearby soft tissues and nerve structures in the spinal canal are reduced.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a percutaneous lamina cutting and drilling precision depth-limited suction cutting 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. From the posterior approach of the spine through the skin and soft tissue to achieve precise, targeted circumcision and drilling of the vertebral lamina and removal of bone fragments to establish a bone channel or partial resection to expand the interlaminar space, so as to establish a surgical path, which is to achieve minimally invasive spinal vertebral surgery. Compared with the traditional open laminectomy technique, the premise of endovascular lesion resection has significant minimally invasive advantages such as les...

Problems solved by technology

In the past, traditional operations were mostly open surgery using lamina rongeurs to bite off the lamina, which required a wide range of paraspinal muscles to be stripped and the structure of the posterior column of the spine to be exposed. The stable tissue structure is seriously damaged, the iatrogenic trauma is large, and the operation efficiency is low, and the postoperative recovery is slow. Additional internal fixation devices are required to rebuild the stability of the spine, resulting in the loss of motion segments and high surgical costs.
