Auxiliary fixing device for labial gland biopsy

Abstract

The invention discloses an auxiliary fixing device for labial gland biopsy, which effectively solves the problems of inconvenience in fixing a surgical site and poor fixing effect during labial glandbiopsy. The device comprises a box body, supporting blocks are arranged on the box body, a flat plate is slidably connected to the upper end of the box body, a rotating shaft is rotatably connected tothe front side of the supporting block on the left side, and a kidney-shaped ring is arranged at the lower end of the rotating shaft; a supporting rod is arranged at the upper end of the rotating shaft, the clamping mechanism is arranged on the front end of supporting rod and comprises a sleeve, a connecting plate is slidably connected into the sleeve, a pressing plate is hinged to the right endof the connecting plate, a gear is rotatably connected to the pressing plate, a screw is arranged at the upper end of the gear, a fixing plate is arranged at the upper end of the pressing plate, inserting plates are arranged at the front end and the rear end of the fixing plate respectively, and a sliding groove is formed in the pressing plate. A rack is slidably connected into the sliding groove,L-shaped plates are arranged on the connecting plate, a sliding block is slidably connected between the two L-shaped plates, the right end of the sliding block can make contact with the upper end face of the pressing plate, and the right end of the sliding block is hinged to the rack through a connecting rod. The device is novel in conception, ingenious in structure, convenient to operate and high in practicability.

Description

technical field [0001] The invention relates to the technical field of auxiliary instruments for lip gland biopsy, in particular to an auxiliary fixation device for lip gland biopsy. Background technique [0002] The most widely used diagnostic criteria for Sjogren's syndrome (SS) are the classification criteria proposed by the American-European Consensus Group (AECG) in 2002, including 2 subjective symptoms of dry mouth and dry eyes, 2 objective evidences of salivary gland and lacrimal gland involvement, Antibody test and labial gland biopsy. The new criteria of the American College of Rheumatology (ACR) in 2012 include serological examination, labial gland biopsy, and corneal and conjunctival staining, and do not include subjective symptoms such as dry mouth and dry eyes, so the specificity of SS diagnosis is relatively high. It can be seen that the importance of pathology in the diagnosis of SS is increasing day by day. Given the serious complications of SS, early diagn...
