Retractor for neurosurgeries

Abstract

The invention discloses a retractor for neurosurgery, which comprises a retractor arm and an arc-shaped support plate, the front end of the retractor arm is equipped with an arc-shaped support plate, and the retractor arm is smoothly connected with the handle of the retractor. The inner side of the front end of the retracting arm is provided with an empty slot, and a miniature lighting lamp is installed inside the empty slot, the top of the empty slot is provided with a vertically downward connecting rod, and the bottom end of the connecting rod is provided with a rotating ball , the miniature illuminating lamp is provided with a ball groove, the rotating ball is stuck inside the ball groove, the miniature illuminating lamp is provided with a control rod passing through the empty groove, and the retracting arm is close to one end of the handle of the retractor There is a threaded rod passing through the two retracting arms, one end of the threaded rod is fixedly connected with the adjusting knob, and the other end of the threaded rod is provided with a nut, and the nut is close to the outside of the retracting arm. The retractor for neurosurgery is reasonable in design, simple in structure, easy to operate, small in size, well exposed in the operation field, convenient for observation, and precise in control, and can be widely used.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, in particular to a retractor for neurosurgery. Background technique [0002] During neurosurgical skull or spine surgery, it is often necessary to retract the skin and muscle tissue. At this time, a retractor is needed to assist the operation. The retractor can be used to retract the tissue, expose the surgical field, and facilitate exploration and operation. [0003] However, the commonly used retractor is a retractor made of the principle of leverage. The total volume occupied by the retractor is large, which affects the exposure of the surgical field during the operation. In the neurosurgery process, a good surgical field Exposure can be said to be one of the keys to the success of the entire operation. If the commonly used retractors want to obtain a good surgical field exposure, they need to cut a larger opening to the patient, which causes the patient's postoperative wound to h...

[0003] However, the commonly used retractor is a retractor made of the principle of leverage. The total volume occupied by the retractor is large, which affects the exposure of the surgical field during the operation. In the neurosurgery process, a good surgical field Exposure can be said to be one of the keys to the success of the entire operation

In order to obtain a good exposure of the surgical field with the commonly used retractor, it is necessary to cut a larger opening for the patient, resulting in slower postoperative wound healing and bringing pain to the patient
