Abstract

The invention relates to the technical field of medical apparatuses and appliances, in particular to a pre-auricular fistula surgery auxiliary device. The device comprises a placement plate I, a placement plate II, a threaded rod, a clamping mechanism and two sets of fixing belts. Supporting arms I are hinged to the two ends of the placement plate A, the placement II is located between the two supporting arms I, a bearing is installed, one end of the threaded rod penetrates through a threaded hole in the placement plate I and then is sleeved with the bearing, a handle is installed at the otherend, supporting arms II are hinged to the two ends of the placement plate II, the other ends of the supporting arms II are hinged to the interior of the front end of a through groove, connecting rodsare installed at the bottoms of the front ends of the supporting arms I, an opening part is installed at the front end of an opening rod, the clamping mechanism is rotationally installed on the placement plate I, and the fixing belts are correspondingly installed at the front end of the placement plate I. Just by adopting the integrated device, incision operation is performed after the fistula atan incision is opened, the operation is simplified, and safety is improved.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to an auxiliary device for preauricular fistula operation. Background technique [0002] Preauricular fistula is a congenital defect caused by congenital underdevelopment. The opening of preauricular fistula is mostly located in front of the crus of the helix, and a few can be located in the triangular fossa of the auricle or the cavity of the concha. Usually asymptomatic. When pressing, there may be a little thin mucus or milky white sebum-like substance overflowing from the fistula opening, and the local area feels itchy and uncomfortable. Asymptomatic or non-infected persons may not be treated. When local itching or pricking occurs, there is discharge overflowing. Sometimes there is often a little white discharge with a slight smell around the small eyes when gently squeezed. [0003] In the prior art, surgery is mainly used to remove the treatment. The operation i...
