Description

The maxillary sinus endoscope of band biopsy needle

Technical field

This utility model relates to a kind of improvement of endoscope, specifically a kind of maxillary sinus endoscope with biopsy needle.

Background technology

Chronic maxillary sinusitis is outpatient service commonly encountered diseases and frequently-occurring disease, along with carrying out of endoscopic surgery, the middle nasal meatus of employing hiatus sinus maxillarises enlarge the treatment maxillary sinusitis more, also have and much carry out the inferior nasal meatus treatment of windowing,, use earlier puncture needle pore-creating when nasal meatus pore-creating is treated, this puncture needle comprises that pluckings nook closing member of prismatic and bodkin cover constitute, the pluckings nook closing member of prismatic is enclosed within the bodkin cover, after the pore-creating success, extracts the pluckings nook closing member of prismatic out, in the bodkin cover, insert endoscope again, make the position with the endoscopic observation disease, used endoscope is by lens barrel, eyeglass constitutes, because the maxillary sinus lacuna is bigger, and lens barrel can not turn to bending, after pathological changes during one side place, needs the endoscope with the oblique eyeglass of configuration in the maxillary sinus chamber, finds lesion locations, extract endoscope out, in the bodkin cover, stretch into biopsy needle or biopsy forceps again, by estimated position incisional biopsy tissue, the method for this incisional biopsy tissue, because it is not visible, it is inaccurate easily to produce the location, causes the biopsy sampling inaccurate, and then influences diagnosis effect.

Summary of the invention

Technical problem to be solved in the utility model provide a kind of can be under endoscope monitors, can accurately cut the maxillary sinus endoscope of the band biopsy needle of pathological changes biopsy, so that the biopsy that takes out is correct, to improve diagnostic level.

For solving above technical problem, the technical scheme that this utility model adopted is: the maxillary sinus endoscope of this band biopsy needle is by lens barrel, eyeglass constitutes, the plane of eyeglass vertically lens barrel axis is provided with or is tilting with the lens barrel axis, as becoming 30 degree angles to be provided with, the diameter of lens barrel is 4mm, establish the latent window of putting of biopsy needle at the lens barrel front end, on the lens barrel outer wall, establish a left side, right two conduits, the biopsy syringe needle is latent to place that biopsy needle is latent to be put in the window, establish two tractive steel wires of fixedlying connected in the right conduit, establish the puncture guide rod of fixedlying connected in the left conduit with the nook closing member of biopsy syringe needle with the biopsy syringe needle; This utility model is also implemented by following measure: described biopsy syringe needle is made of syringe and nook closing member, syringe is thin cylindrical tube shape, long 5mm, lens barrel is provided with insertion depth scale sign, when the eyeglass insertion depth scale of endoscope reaches the rotatable position mark of biopsy syringe needle, promptly surpass when fixedly the pore-creating bodkin overlaps end 5mm, the biopsy syringe needle can turn to, the biopsy syringe needle is screwed out, the diameter 3mm of syringe, insert when biopsy needle is latent puts window, can account for half of lens barrel, can not influence in lens barrel and spy on, syringe prosopyle edge is a bladed, the nook closing member front end is established barb, so that hook up biopsy, after hooking biopsy, by the puncture guide rod nook closing member of pulling back, biopsy is just cut in the syringe, the tail end of nook closing member is connected with the puncture guide rod, a left side, the syringe end wall that right two tractive steel wires pass right conduit and biopsy syringe needle is connected and fixed, rotate the tractive steel wire biopsy syringe needle is rotated, thereby the biopsy syringe needle is spun out, promote the tractive steel wire biopsy syringe needle is stretched out, by a left side, it is different that right two tractive steel wires are stretched the elongation degree, can realize the biopsy syringe needle to a lateral bending song, the puncture guide rod passes left conduit and the nook closing member tail end is connected and fixed, and the puncture needle guide rod is the flexible axle shape, by promoting the puncture needle guide rod, the puncture nook closing member is entered in the pathological tissues; On lens barrel, also be provided with insertion depth scale sign, with insertion depth and the rotating position of biopsy needle of observing lens barrel accurately.When using this utility model, can use the pluckings puncture needle pore-creating of prismatic earlier, and the bodkin cover is trapped in the pore-creating, to insert the bodkin cover with the maxillary sinus endoscope of biopsy needle again, when being inserted into the rotating position mark of biopsy syringe needle, promptly rotatable tractive steel wire produces the biopsy syringe needle, and then by promoting two tractive steel wires it is protracted, stretch by the length of two tractive steel wires again and draw adjustment, make the one root be arc, one is profound shape, can make the biopsy syringe needle bend to the lesion locations that arrives by endoscopic observation, promote the puncture guide rod again, make nook closing member thrust pathological tissues, the sampling of pulling back again, got sample after, the two tractive steel wires of pulling back again, reduce, extract endoscope at last, this process can be carried out under endoscopic observation.

The beneficial effects of the utility model are: checking, spy on, get biopsy can disposablely finish, and saves time, laborsaving, and whole process is carried out under spying on entirely, rapidly, accurately, has improved the accuracy of biopsy.
