[0016] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] See also Figure 1 Combination Figure 2-Figure 3 As shown, the embodiment of the utility model includes:

[0018] An asymmetric retractor comprises a clamp handle, a branchial axis screw 1 and a retractor sheet.

[0019] The clamp handle comprises a first clamp handle 2 and a second clamp handle 3 , and the first clamp handle 2 and the second clamp handle 3 are connected and fixed by a gill axis screw 1 , so that the first clamp handle 2 and the second clamp handle 3 can be opened and closed around the gill axis screw 1 .

[0020] The first and second mounting grooves 4 and 5 are respectively provided at the rear of the first and second clamp handles 2 and 3. A fixed rack 6 is provided in the first mounting groove 4 and passes through the second mounting groove 5. The fixed rack 6 and the first mounting groove 4 are riveted and then fixed by argon arc welding. The installation is convenient and the fixation is stable. A movable rack 7 is hingedly provided in the second mounting groove 5 by rivets to mesh with the fixed rack 6. The first and second clamp handles 2 and 3 can be positioned by the cooperation of the movable rack 7 and the fixed rack 6 at different positions when opening and closing.

[0021] A support spring 9 is fixed to the second clamp handle 3 through a support spring screw 8 and is pressed correspondingly with the end of the movable rack 7 to ensure stable fixation after positioning.

[0022] The retraction piece includes a first retraction piece 10 and a second retraction piece 11. The first retraction piece 10 and the second retraction piece 11 have different structures and are respectively fixed to the front ends of the first clamp handle 2 and the second clamp handle 3 for retraction support during surgery. The top of the second retraction piece 11 is fixed to the second clamp handle 3 by argon arc welding. They are individually processed according to the required structure and then assembled to meet different usage requirements.

[0023] The first retractor 10 is arranged parallel to the branchial axis screw 1 and has a longitudinally distributed first tooth surface 12 on the outer side for retracting and positioning at the left side, and a second tooth surface 13 is arranged on the bottom.

[0024] The second retraction piece 11 is arranged in a stepped structure. The longitudinal inner side surfaces of the second retraction piece 11 are respectively provided with transversely distributed third tooth surfaces 14, and the bottom is provided with a fourth tooth surface 15. The stepped structure realizes the degree of retraction at different positions, avoids synchronous retraction at different positions of the surgical site, and reduces the size of wounds of different depths of the injured person.

[0025] The first tooth surface 12 and the third tooth surface 14 are arranged opposite to each other to provide stable support during distraction.

[0026] In summary, the asymmetric retractor disclosed in the utility model has a simple, reasonable and reliable structure, can realize layered retraction according to different wound depths, reduces the retraction area, and facilitates rapid healing of the wounded after surgery.

[0027] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
