Background technology
Under scope, biopsy is the large advantage that scope interventional technique is learned than irradiation image, and this technology makes endoscope (digestionScope, bronchoscope, soft ureteroscope) not only can obtain the image of pathology, can also obtain pathological tissues and carry out pathologyLearn and check, for further diagnosis and treatment provide important information. In the biopsy forceps that under scope, biopsy is used is designed to pass throughThe instrument that sight glass biopsy channel arrives at cavity lesion and pathological tissues is sampled, the tong arm that it comprises elongated bendable and littleClamp flexibly ingeniously tooth. The tong arm of elongated bendable can adapt to the long and narrow how curved environment of biopsy channel, and pincers tooth can arrive atThereby, manipulate its switching realization by the handle of the tong arm other end gets the pincers of pathological tissues when in the precalculated position. Biopsy forceps becomesFor one of endoscopic necessary equipment. But existing biopsy forceps only has the effect that pincers subtract conventionally, and real processIn, except the polyp forceps at colon pleat rear is subtracted sampling, also tend to adopt other equipment to enter gastric juice and intestinal juiceComprehensive consideration is carried out in row sampling. Therefore, tend to repeatedly equipment be stretched in patient body, cause patient's serious discomfort. InstituteWith, be badly in need of a kind of equipment that once can complete sampling when subtracting with gastric juice to the pincers of polyp, to reduce patient's misery.
Utility model content
The purpose of this utility model is providing a kind of biopsy forceps, sampling when once can completing polyp and gastric juice.
In order to achieve the above object, base case of the present utility model is: biopsy forceps, comprises the work that is provided with pincers tooth and tong armInspection pincers body, wherein, also comprises collector tube, sleeve pipe and air bag, and described casing pipe sleeve is located on collector tube, and joins with collector tube screw threadClose, the sidewall of described collector tube is provided with the first liquid outlet, and described sleeve pipe is provided with corresponding with the first liquid outlet second and goes outLiquid mouth, described pincers tooth is provided with inlet, and described tong arm is provided with liquid collecting passage, and this inlet is by described liquid collecting passage and collectionLiquid pipe is communicated with.
The principle of this base case is: biopsy forceps inserts in stomach and clamps in the meat of cutting rates, and first presses air bag, thenThis device is inserted in stomach, until pincers toe joint contacts gastric juice or needs the liquid sampling, pincers tooth is drawn onto collector tube by gastric juiceIn store. Afterwards, can clamp the operation of the meat of cutting rates. Rotating casing, when the first liquid outlet and the coincidence of the second liquid outletTime, the gastric juice in collector tube can be taken out.
The beneficial effect of this base case is: this programme produces negative pressure by air bag and draws gastric juice, and gastric juice entersAfter collector tube, be difficult for flowing back in stomach. Sleeve pipe and collector tube threaded engagement, make the gastric juice in collector tube be difficult for spilling. With traditionBiopsy forceps compare, this programme only need insert biopsy forceps in stomach once, sampling when can completing polyp and gastric juice is largeLarge minimizing patient's misery.
Scheme two: what this was base case is preferred, and described liquid collecting passage is provided with check valve. Make the gastric juice can only be from stomachEnter collector tube, further avoid gastric juice to come back in stomach.
Scheme three: this is the preferred of scheme two, and described pincers tooth and tong arm are stainless steel and make. Because gastric juice is acid,Pincers tooth and tong arm that stainless steel is made have good corrosion resistance, longer service life.
Scheme four: this be base case to any one scheme in scheme three preferably, the surface of described sleeve pipe is provided with anti-skiddingLayer. Skid resistant course can increase the frictional force between sleeve pipe and hand, avoids making whole biopsy forceps shake because hand skids.
