Distraction hook in lumbar surgery

Abstract

The invention relates to a distraction hook in a lumbar surgery and effectively solves the problems that an existing distraction hook for a lumbar surgery is single in function and inconvenient to use. By means of the distraction hook for a lumbar surgery, surgical incisions of a patient can be reduced as much as possible; the surgical operation space is increased to the greatest extent for doctors at the tissue part in the body of the patient; in order to avoid rebound of a deep tissue structure, expansion plates are slidably mounted in second ejector rods correspondingly, after the second ejector rods slide outwards by a certain distance, the two expansion plates slide outwards, the distraction area of the deep soft tissue structure is increased, and the situation that the portion, not making contact with the second ejector rods, of the deep tissue structure rebounds outwards, and consequently the situation that the surgical operation space is occupied is avoided.

Description

technical field [0001] The invention relates to the technical field of lumbar spine surgery assistance, in particular to a distraction hook in lumbar spine surgery. Background technique [0002] In the existing lumbar spine surgery, the doctor will cut an incision along the direction of the spine and then use a spreader to open a certain opening for the tissues on both sides of the spine, so that the patient's lumbar spine and spine are exposed to facilitate the doctor's operation. Among them, due to the long time of spinal surgery, it is necessary to keep the spreader open for a long time. Since the spreader cannot be easily shaken during the operation, if the shake occurs, the opening will be narrowed, which will affect the doctor's surgical sight, thereby increasing the chance of surgical failure. Risk, if the opening becomes larger, it may cause a surge of blood in the patient's spine, resulting in failure of the operation; [0003] When doctors perform lumbar spine sur...

[0002] In the existing lumbar spine surgery, the doctor will cut an incision along the direction of the spine and then use a spreader to open a certain opening for the tissues on both sides of the spine, so that the patient's lumbar spine and spine are exposed to facilitate the doctor's operation. Among them, due to the long time of spinal surgery, it is necessary to keep the spreader open for a long time. Since the spreader cannot be easily shaken during the operation, if the shake occurs, the opening will be narrowed, which will affect the doctor's surgical sight, thereby increasing the chance of surgical failure. Risk, if the opening becomes larger, it may cause a surge of blood in the patient's spine, resulting in failure of the operation;

[0003] When doctors perform lumbar spine surgery, they usually perform bone grafting or implant some internal fixation devices on the patient. Since it is necessary to pass through multiple tissue structures from the surface of the human skin to the surgical site of the spine, in order to provide doctors with greater surgical operations It is often necessary to make a larger incision in order to facilitate the entry of internal fixation instruments and bone grafting, which will cause extensive local damage, directly lead to an increase in intraoperative bleeding, and postoperative pain and discomfort for patients. Postoperative functional exercise and rehabilitation of patients;
