Description
Technical field
The present invention relates to a kind of micro-laryngeal scissors.
Background technology
The benign lesion of clinical common vocal cords mainly occurs in the shallow-layer (thick about 0.5mm) of mucosal epithelium layer (thick about 0.05 ~ 0.1mm) and Submucosa, must use when needing in art to cut off pathological tissues or too much mucosa as far as possible meticulous micro-laryngeal scissors accurately, gentle manipulation, in order to avoid excessive damage mucosa and vocal ligament.In some cases, need on the axis of front and back, to rotate vocal cords lightly with meticulous pincers, to observe the basilar part of polyp of vocal cord better.At present, the micro-laryngeal scissors of tradition adopts crocodile mouth formula, because vocal cords medial border is curved, during clamp, tissue depth and dynamics are not easily grasped, clamp is organized and very fewly may not had traction action, clamp too much easy damaged vocal ligament and too much mucosa, repeatedly the damage that certainly will increase vocal cords mucosa attempted by clamp, give to prune and increase difficulty, in addition, laryngeal forceps affects laryngeal scissors effect and working place to a certain extent, and when laryngeal scissors is pruned along basilar part, depth dynamics is not easily grasped, and slight jitter can cause the accidental injury of vocal cords and ligament.In addition, some need the poor of excision and the mucosa of softness or pathological tissues are attached in vocal cords normal structure time, use traditional micro-laryngeal scissors clean cut to be a very large challenge to patient.
Summary of the invention
The technical problem to be solved in the present invention, be to provide a kind of micro-laryngeal scissors, comprise conduit, handle apparatus and negative pressure suction device, described tube at one end is closed, the other end is open, the open end of described conduit connects negative pressure suction device, and described handle apparatus is arranged on conduit and also arranges near catheter patency end; The blind end of described conduit is provided with suction unit, and this suction unit is provided with suction hole, the first blade and the second blade, the pipeline communication in described suction hole and conduit; Described conduit is provided with snap ring and guide rod, described snap ring is provided with through hole, described guide rod is connected with the second blade through the through hole of snap ring, described handle apparatus comprises the first handle and second handle that are hinged, described first handle and the guide rod other end hinged, described second handle is fixed on conduit; Described first handle can drive the relative snap ring slippage of guide rod around rotating with the hinged place of second handle, thus drives the folding of the first blade and the second blade.
Further, described snap ring and guide rod are located in the pipeline in conduit.
Further, conduit outside is located at by described snap ring and guide rod, and wherein snap ring is welded on conduit outer wall.
Further, corresponding first blade of described second blade reaches the tube wall outside of conduit.
