A kind of internal medicine alimentary canal biopsy forcepsTechnical field
The present invention relates to the field of medical instrument technology, specially a kind of internal medicine alimentary canal biopsy forceps.
Background technique
Currently, being clinically that patient is allowed to swallow with hairbrush mostly when carrying out esophageal cast-off cell extraction biopsy to patientAir bag, then inflate, make air bag expansion extract mucous membrane cast-off cells, the operation is very troublesome, time-consuming and laborious in this way, and be easy damageHurt mucosal tissue, existing biopsy sampler is difficult to control the insertion depth of air bag, and air flow rate and speed in flexible conduitIt is not easy to monitor, judges that air bag degrees of expansion increases difficulty to medical worker, in addition biopsy sample falls off easy during taking-upIt falls off.
But there are deficiencies below for existing technology：
1, the method for existing alimentary canal living body sampling allows patient to swallow the air bag with hairbrush, keeps air bag swollen by inflationSwollen extraction mucous membrane cast-off cells, the operation is very troublesome, time-consuming and laborious in this way, and is easy to damage mucosal tissue.
2, existing alimentary canal biopsy forceps are not very perfect, the air-flow in air bag in the assurance of sampler depthFlow, speed are not easy to monitor, and judge that air bag degrees of expansion increases difficulty to medical worker.
3, the spatula of existing alimentary canal biopsy forceps scrapes off rear biopsy sample and is easy to fall off during taking-up, causesIt samples sample to reduce, gives patient and doctor's all brings many troubles.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of internal medicine alimentary canal biopsy forceps, sampling is solvedDevice is sampled the problem that object is easy to fall off, accuracy is not high and operation is not easy to control in sampling.
To achieve the above object, the present invention provides the following technical solutions：A kind of internal medicine alimentary canal biopsy forceps, includingSampler main body is equipped with spatula inside the storage slot that the sampler main body is equipped with, and the bottom of the spatula, which is welded on, to push awayOn plate, the push plate is mounted on the sliding rail of the inner wall of sampler main body, the both ends underrun spring and sliding rail of the push plateSide wall be fixedly connected, depth transducer is installed on the shell of the sampler main body, visits lamp and radio transmitting device, it is describedDepth transducer is located at the side of radio transmitting device, and the inside of the sampler main body is equipped with button cell and air bag, instituteThe connector for stating air bag is connect with one end of the flexible conduit of the shell of sampler main body, and the other end of the flexible conduit passes through connectionMouth is connect with air pump, throat pad, air valve and flowmeter is equipped on the flexible conduit, the air valve is located at the connector of air pumpSide, the flowmeter are arranged between throat pad and air valve, and the operation panel installed on the air pump is equipped with display screen, describedThe one of air pump is equipped with power interface, and the power interface is connected respectively at operation panel with air pump by conducting wire.
Preferably, the button cell is connect with depth transducer, spy lamp and radio transmitting device respectively by conducting wire.
Preferably, the spy lamp and depth transducer are wirelessly connected with operation panel and display screen respectively by radio transmitting deviceIt connects.
Preferably, the air bag is arranged between a pair of push plates of sampler body interior installation.
The present invention provides a kind of internal medicine alimentary canal biopsy forceps, have following beneficial effect：
(1) present invention is by setting sampler main body, and sampler main body is equipped with storage slot, and spatula setting is in storage slotThe bottom in portion, spatula is fixed in push plate, controls air pump by operation panel, and then control the size of air bag, air bag becomes larger promotionPush plate, push plate move in sliding rail, and push plate drives spatula to lean out storage slot, by observation flowmeter and adjusting air valve, control gasCapsule is pushed the speed, and the spring of the bottom surface installation of push plate also plays constraint to the forward speed of push plate, and the spatula avoided scratchesOrgan is exhausted air bag when recycling to sampling object, and push plate recycle spatula under the elastic force effect of springTo storage slot, advantage is that preventing spatula to scrape off rear biopsy sample is easy to fall off during taking-up.
(2) present invention visits lamp, radio transmitting device and depth transducer by setting, visits lamp, depth transducer passes through nothingLine transmitting device is connect with display screen respectively, is visited lamp and is launched gastral situation on a display screen by radio transmitting device,Depth transducer is shown the position of sampler main body on a display screen by radio transmitting device, cooperates the quarter on flexible conduitDegree holds sampler main body specific location, improves the accuracy of medical procedure, and the throat pad being arranged on flexible conduit is given in living bodyThe discomfort that throat is reduced in sampling process influences the process and effect of entire sampling process.
