Abstract

The invention belongs to the technical field of medical devices, and discloses a three-way minimally invasive lumbar vertebra retractor, which is provided with a fixed disk, and a connecting rod is welded horizontally inside the fixed disk, and a rotating rod is sheathed inside the connecting rod; The front end of the rotating rod is welded with a fixed seat, and the three-way traction hook is fixedly installed on the fixed seat by bolts; the rotating rod at the rear end of the fixed seat is sleeved with a sliding plate, and the sliding plate is welded with a second adjusting rod, The end of the rotating rod is welded with a first adjusting rod. The invention is provided with a traction hook applied to lumbar spine surgery, and is provided with a three-directional traction hook. Compared with the traditional opposite traction hook, the three-directional traction hook has an average traction force in three directions, reduces the amount of bleeding in the wound, facilitates the work of the doctor, and reduces the The patient's postoperative recovery time, and the three-way traction hook can be slidably adjusted, which is convenient for adjusting the position of the three-way traction hook for different parts of different patients, which is convenient for doctors to perform operations.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a three-way minimally invasive retractor for the lumbar spine. Background technique [0002] At present, the existing technology commonly used in the industry is as follows, [0003] The retractor, also known as the retractor body, is used to retract the tissue, expose the surgical field, and facilitate exploration and operation. It can be divided into two types: a hand-held retractor body and an automatic retractor body. There are various specifications of different shapes and sizes, and the appropriate retractor body can be selected according to the operation needs. The thyroid puller is also called the body of the right-angle retractor, which is in the shape of a flat hook. It is often used to pull and expose the thyroid gland, and is also commonly used in other operations. It can retract the skin, subcutaneous tissue, muscle and fascia, etc. The S-shaped retractor b...
