Description

Curved larynx polyp bites cutting pliers

Technical Field

The utility model relates to the technical field of vocal cord polyp resection instruments, in particular to a pair of biting and cutting pliers for bent laryngeal polyps.

Background

The method is a common operation mode at present, the benign lesions of vocal cords such as polyps of vocal cords are removed by using a laryngeal polypus forceps under a support laryngoscope, the clinically common benign lesions of vocal cords are mainly generated on the epithelial layer (the thickness is about 0.05-0.1 mm) of a mucous membrane and the superficial layer (the thickness is about 0.5 mm) of the submucosal layer, and the fine laryngeal forceps must be used for accurate and soft operation as much as possible in the operation so as to avoid excessively damaging the mucous membrane and the vocal cords. However, the existing laryngeal polypus forceps are of a contra-occlusal type, have small occlusal force, are easy to cause mucous membrane avulsion when benign lesions such as vocal cord polyp are resected, damage the vocal cord mucous membrane of a lesion-free part, cause vocal cord defect and incomplete glottis closure, can remain tiny lesions, influence the accuracy and precision of operation and influence the recovery of postoperative sound.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems that the existing laryngeal polypus forceps are of opposite-mouth occlusion type and have small occlusion force, the utility model provides the curved laryngeal polypus biting and cutting forceps which have larger occlusion force and can accurately and accurately cut vocal cord lesion.

The utility model adopts the technical scheme that the above purpose is realized: the utility model provides a crooked larynx polyp bite and cut pincers, includes fixed pincers handle, activity pincers handle, binding post, pull rod, fixed binding clip and activity binding clip, the binding post is the arc, and fixed pincers handle is connected to the one end of binding post, and fixed binding clip is connected to the other end of binding post, and the one end of pull rod is connected movable pincers handle, and the other end of pull rod passes the end-to-end connection of binding post and activity binding clip, and fixed pincers handle is articulated with the activity pincers handle, and the end of activity binding clip is articulated with the end of fixed binding clip to be the structure that opens and shuts, is equipped with the holding chamber in the fixed binding clip, and the front end of activity binding clip and fixed binding clip all is convex structure, and the outer fringe of activity binding clip is identical with the inner edge of fixed binding clip, forms seamless interlock connection when activity binding clip and fixed binding clip are closed.

Furthermore, the bottom of the accommodating cavity of the fixed tong head is of a hollow structure, and the bottom of the accommodating cavity is provided with spacing bars distributed at intervals.

Furthermore, the division bars are distributed at intervals in the transverse direction.

Furthermore, the distance between the division bars is 0.5-1 mm.

Furthermore, the fixed clamp handle and the movable clamp handle are in a scissor type structure.

Further, the radian of the clamp rod is 1.22 degrees.

Furthermore, the movable clamp head is of a solid structure.

The utility model has the technical effects and advantages that: according to the curved laryngoscope biting and cutting forceps provided by the utility model, the outer edge of the movable forceps head is matched with the inner edge of the fixed forceps head, and seamless meshing connection is formed when the movable forceps head and the fixed forceps head are closed, as the vocal cords are opened and closed, polyps are usually positioned on the edges of the vocal cords, and after the polypus forceps enter a laryngeal cavity, the polyps are positioned on the left side or the right side of the laryngeal forceps, the polyps can be directly contained in the forceps by the movable forceps head and the fixed forceps head, the biting force is higher, vocal cord pathological changes can be accurately and accurately cut, the polypus can be directly bitten and cut during a vocal cord polypus operation without being pulled forcefully, and the problems of postoperative sound recovery caused by tearing of the vocal cord mucous membranes and residue of tiny pathological changes are avoided; compared with the existing laryngeal polypus scissors, the angle of the laryngeal polypus scissors is more convenient for directly cutting off the polyps, the cut-off polyps can be directly taken out, the cut-off polyps are prevented from falling off and entering an air passage, the operation after the polyps are pulled by another laryngeal forceps is not needed, two instruments are prevented from entering a narrow laryngeal cavity at the same time, and the operation is more convenient; the radian of the forceps rod is 1.22 degrees, and is calculated according to an applied biomechanics model, so that the radian has small pressure on the tongue body, does not influence an exposed operation area, and is the optimal radian; the holding chamber bottom of fixed binding clip is hollow out construction to be provided with interval distribution's parting bead in holding chamber bottom, at first, this holding chamber can effectively prevent the polyp of excision from droing, can directly the clamp take out the larynx chamber after the excision, and secondly, the holding chamber of fretwork compares with non-fretwork, and is lighter to the extrusion of tissues such as the polyp of excision, and the tissue is more complete when the censorship pathology, and the result is more accurate.
