Chinese patent application number: 201210199076.2 discloses a pull hook device capable of adjusting the surgical incision in all directions, including the pull hook, which is characterized in that it also includes a main body frame composed of a column, a cantilever, and a base, wherein the front end of the cantilever is connected to an opening six Edge arms, wherein the four edge arms are provided with pull hook orientation and tightness adjustment devices, each pull hook orientation and tightness adjustment device can move on the edge arm where it is located, and there are at least four pull hooks, each pull hook One end is evenly hooked around the patient's surgical incision; the other end of each retractor is connected to the respective retractor position and elastic adjustment device, the cantilever is located above the operating table, and can move horizontally back and forth and up and down on the column; the base is fixed to the column The lower end can drive the main frame to move along the length direction of the operating table.

Although the above invention can adjust the surgical incision in multiple directions, the structure is complex, the cost is high, and the operation is relatively simple.

Utility model content

The purpose of this utility model is to overcome the above-mentioned defects of the prior art, to provide an all-round exposure of the surgical field of view, to enhance the brightness, and to make the surgical site clearer. Surgical retractor device.

In order to achieve the above object, the technical solution provided by the utility model is as follows: an adjustable surgical retractor device, including a retractor frame and a retractor, the retractor frame includes an arc-shaped upper bracket and a lower bracket, and the upper bracket is welded with several cylinders body.

Wherein, the lower bracket includes a left lower bracket and a right lower bracket.

Wherein, the front part of the draw hook is provided with a curved hook head, and the rear part of the draw hook is provided with several circular through holes.

Wherein, there are more than two pull hooks.

Among them, the distance between the circular through-holes is 6 mm to 10 mm, which can cope with the angles and sizes of various incisions in different operations by socketing with each cylinder on the upper support body.

Wherein, the upper bracket can be combined with another identical upper bracket to form a circular upper bracket body.

Wherein, the upper bracket and the lower bracket are respectively connected by screws and nuts.

The utility model is beneficial in that it has a simple structure, can expose the operation field of view in all directions, enhances the brightness, and makes the operation site clearer. At the same time, it does not need a doctor's assistant to assist the retractor, which reduces the labor force.
