Abstract
The invention relates to an aspiration device, in particular to a thrombus aspiration device, and belongs to the technical field of medical instrument structures. The thrombus aspiration device comprises a metal sheath, a rotary cutter and an expander. The metal sheath comprises a metal spiral pipe, a side pipe is arranged at one end of the metal spiral pipe, and one end of the side pipe is movably connected with a first backflow preventing cap. The rotary cutter comprises a crank, a spiral flow guide groove is formed in the end, away from the handle, of the rotary cutter, a second backflow preventing cap is arranged at the end, close to the handle, of the rotary cutter, and a blade is arranged between the second backflow preventing cap and the spiral flow guide groove. The thrombus aspiration device can replace an original long metal sheath, the expander is withdrawn, the rotary cutter is fed in, the thrombus aspiration device is formed, the side pipe generates negative pressure through pumpback of an injector, thrombus is made to enter the metal sheath, the rotary cutter is rotated, the thrombus is conveyed to move into a lumen under the combined action of the rear driving force of the flow guide groove and the negative pressure, the middle blade cuts the thrombus into small blocks, the thrombus is sucked out of the side pipe, the situation that large thrombus blocks block the pipe cavity, and consequently the aspiration process is interrupted is avoided, operation efficiency is improved, and operative complications are reduced.
Description
Technical field
The present invention relates to a kind of aspirator, Biochemical analyzer device in, belongs to technical field of medical appliance structures specifically.
background technology
In the intervene operations such as veins of lower extremity or caval vein thrombosis, need application catheter sheath or large cavities conduit pipe aspirate thrombi.Because part thrombosis quality is compared with hard and volume ratio catheter lumen is large, easily block catheter lumen, cause each aspirate thrombi quantity few, and need repeatedly to take out catheter sheath or large cavities conduit pipe, insert catheter sheath or large cavities conduit pipe again, thrombosis all could be extracted out, such repeatable operation, cause the efficiency of suction low, operation time is extended, and the incidence rate of complication is also corresponding to be increased, as there are inner film injury, severe loss of blood and postoperative infection etc.
The current operating theater instruments without special aspirate thrombi, many application catheters sheath or large cavities conduit pipe carry out aspirate thrombi, the inefficiency of suction, complex operation, increase operation time, cause very big inconvenience to operation.
Summary of the invention
The object of the invention is to the weak point solving the existence of above-mentioned prior art, provide a kind of structure simple and direct, easy to use, improve the Biochemical analyzer device of Biochemical analyzer efficiency.
A kind of Biochemical analyzer device of the present invention, its special character is to comprise metal sheath, peeling knife and dilator, and described metal sheath comprises metallic coil 1, and one end of metallic coil 1 is provided with side pipe 2, and one end of side pipe 2 is connected with the anti-cap 1 that backflows; Described peeling knife comprises crank 7, and the one end away from handle 8 offers spiral stream guidance groove 4, and be provided with the anti-cap 26 that backflows near one end of handle 8, the centre of backflow cap 26 and spiral stream guidance groove 4 is provided with blade 5; Described metal sheath and dilator are with the use of the effect realizing the long sheath blood vessel dilating of common metal, and described metal sheath and peeling knife are with the use of the function realizing Biochemical analyzer;
Described side pipe 2 is provided with the connection tube 9 be connected with syringe;
Described anti-cap 26 and the blade 5 of backflowing is arranged on crank 7.
A kind of Biochemical analyzer device of the present invention, the long sheath of original metal can be replaced, do not increase the financial burden of patient, consistent with the function of the long sheath of original metal after inserting dilator, withdraw from dilator, after sending into peeling knife, become Biochemical analyzer device, side pipe is through syringe pump, cause negative pressure in metal sheath, thrombosis is sucked and enters in metal sheath, rotate peeling knife, drive after front end spiral type guiding gutter produces thrombosis, thrombosis is carried to move in tube chamber with negative pressure combined effect in tube chamber, by during the blade of middle part, thrombosis is cut into small pieces, through side pipe sucking-off, avoid massive to block tube chamber and make aspirate thrombi process interrupt, make operation more convenient, reduce postoperative complication, it is greatly convenient to bring to medical worker and patient.
