Description
Technical field
This utility model belongs to medical apparatus and instruments apparatus technical field, is specifically related to a kind of biological tissue sample pickup tongs for endoscope.
Background technology
The splanchnoscopies such as gastroscope and intestinal mirror are owing to can observing intuitively the pathological changes at gastrointestinal position, because of but clinical conventional detection methods at present.In endoscopic procedure, doctor is also often by biological tissue sample pickup tongs, first pass through endoscope, make biological tissue sample pickup tongs directly arrive in patient body, employing cuts, clamp and get or the method such as puncture is taken out a certain amount of pathological tissues in patient body, carry out pathological examination, to most censorship cases, can make clear and definite histopathologic diagnosis, this inspection method is that inside of human body pathological tissues is obtained the most efficient approach of pathological diagnosis most convenient, therefore, biological tissue sample pickup tongs uses very extensive in clinical endoscopy examination.
But, there are following two problems in current conventional biological tissue sample pickup tongs: 1, the binding clip of conventional biological tissue sample pickup tongs is owing to can not multi-angle rotating to multiple directions, therefore, it is very inconvenient when pincers are got different azimuth pathological tissues, to there being some remote diseased regions to be even difficult to carry out effectively pincers, get, increase the difficulty of operation, increased patient's misery, 2, because some diseased regions easily rock, conventional biological tissue sample pickup tongs is before pincers are got pathological tissues, can not effectively fix these diseased regions, therefore, when pincers are got pathological tissues, cause to clamp exactly and get best pathological tissues, and the amount of pincers being got to pathological tissues can not accurately be held, sometimes when clamping the pathological tissues of getting more amount, must repeatedly clamp and get, extended the time of patient's operation, also increased the difficulty of operation, increased patient's misery, simultaneously, also greatly reducing doctor diagnoses exactly to pathological tissues.
Utility model content
The technical problems to be solved in the utility model is, a kind of biological tissue sample pickup tongs for endoscope is provided, not only the binding clip of sample pickup tongs can rotate to multiple directions, and when pincers are got pathological tissues, can first to pathological tissues, effectively fix, then clamp and get pathological tissues, thereby improve to a great extent operation efficiency, shorten operating time, alleviate patient's misery.
For overcoming the deficiencies in the prior art, the technical solution adopted in the utility model is: a kind of biological tissue sample pickup tongs for endoscope, comprise binding clip, tong arm, slide handle and hands handle, binding clip comprises two hinged cup-shaped jaws, slide handle is sleeved on the end of tong arm, slide handle inwall is symmetrical arranged two flanges, tong arm end arranges the chute corresponding with flange, slide handle is connected by the steel wire rope being arranged in tong arm with the bottom of cup-shaped jaw, tong arm front end and tong arm rear end are all fixedly installed rotating shaft, the rotating shaft of tong arm front end is provided with the deflecting roller being rotationally connected with tong arm, deflecting roller comprises a bull wheel and the steamboat being fixed together, binding clip is fixed on bull wheel, the rotating shaft of tong arm rear end is provided with the control wheel being rotationally connected with tong arm, control wheel is connected with the steamboat of deflecting roller by stay cord, handle is arranged on the end of tong arm, in binding clip and tong arm, hollow pipe is set, one end sealing of hollow pipe is communicated with adsorbent equipment, adsorbent equipment is between two cup-shaped jaws, the other end of hollow pipe stretches out outside tong arm end and is communicated with negative pressure device sealing.
Described adsorbent equipment forms large sucker by a plurality of small suckers.
Described negative pressure device is syringe.
The beneficial effects of the utility model: 1, the binding clip of biological tissue sample pickup tongs can rotate to multiple directions, very convenient when pincers are got the pathological tissues of different azimuth.The technical program arranges deflecting roller at tong arm front end respectively, in rear end, control wheel is set, when doing splanchnoscopy, if need to pathological tissues be sampled, biological tissue sample pickup tongs can be put into endoscope, by the opening of endoscope distal end, make the binding clip of biological tissue sample pickup tongs stretch out endoscope, arrive at pathological tissues place, pathological tissues for different azimuth, can rotate control wheel, under the effect of stay cord, controlling deflecting roller rotates, because binding clip and the deflecting roller of biological tissue sample pickup tongs is fixed together, thereby can make binding clip along with deflecting roller rotates to multiple directions, thereby pincers are got the pathological tissues of different azimuth easily, to there being some remote diseased regions also can carry out effectively pincers, get.2, between two of binding clip cup-shaped jaws, be provided with adsorbent equipment, for some, be difficult for the diseased region that pincers are tried to please and easily rocked, can be before pincers be got pathological tissues, first with the diseased region that adsorbent equipment is got needs pincers, hold and fix, with biological tissue sample pickup tongs, clamp and get required pathological tissues again, and pincers are taken as exactly the amount of the pathological tissues of determining that the state of an illness is required, easy to operate, saved operating time.
