Abstract

A tissue retractor for use in oral cavity operations is disclosed. The tissue retractor includes an elastic retracting ring capable of deformation retracting and a placement structure. The tissue retractor is characterized in that the front end of the placement structure is a placement unit for the retracted elastic retracting ring; the elastic retracting ring is retracted in the placement unit; the area of cross section of the placement unit is smaller than the area of the elastic retracting ring after the elastic retracting ring extends; a forward pushing structure is arranged behind the placement unit; the area of cross section of the forward pushing structure is not smaller than the area of middle gap of the retracted elastic retracting ring; a forward pushing bar is arranged behind the forward pushing structure; a pushing bar setting unit is arranged at the rear end of the placement structure, and is provided with a pushing bar passage having a size same as that of the forward pushing bar, inside; and the rear end of the pushing bar is connected to a forward pushing button pushing the forward pushing bar. The forward pushing button can be disposed in a pushing button moving slot of a pushing bar placement unit, or disposed in an rear-end groove, or is provided with an extending segment connected to the forward pushing button. In addition, the rear end of the pushing bar setting unit is provided with a rear-end perpendicular segment arranged in a separated manner. Angles of all parts can be adjusted according to operation needs, thus facilitating strength exerting. Thetissue retractor is reasonable in structure setting and convenient to use.

Description

technical field [0001] The invention belongs to medical equipment in the field of stomatology, in particular to a retracting device used in oral surgery, in particular to a tissue retracting device used in oral surgery. Background technique [0002] During the surgical operation, in order to better expose the surgical field, the wound needs to be retracted, and a conventional retractor is usually used clinically to retract the wound directly exposed outside the body. When conventional retractors are applied to oral surgery, they are often difficult to insert because of the concealment of the incision, especially for related fields such as oral plastic surgery and dental implant surgery. [0003] Although there are some instruments for gingival separation in the prior art, most of the instruments need to be adjusted repeatedly on the outside to achieve accurate positioning, such as the adjustable gingival separation fixer for dental implant surgery 201520152475.2 and a gingiv...
