Abstract

The utility model provides a double-tube cutting endoscope suction remover which is cooperatively used with the minimally invasive operation of an endoscope. The remover provided mainly includes a cutting pipe, a piston, a vacuum chamber, a sealing ring, a return spring and a handle. Soft tissues, such as hematoma, are partially sucked into the cutting pipe by means of vacuum; When the vacuum degree is not high, the cutting pipe can move back and then cooperates with the mechanical channel of the immovable endoscope to cut off the tissues, the cut-off tissues are sucked away under the low vacuum degree, and the cutting pipe is returned to the original position to start a new process. In this way, the tissues are automatically and continuously removed.

Description

Two-tube cutting scope attracts remover
Technical field
The present invention relates to a kind of soft tissue and remove equipment, particularly relate to a kind of two-tube cutting scope and attract remover.
Background technology
Minimally Invasive Surgery has become trend at present, and the normal endoscope that uses of Minimally Invasive Surgery also is widely used thereupon.The intravital soft tissue of people will take out by the aperture that has only several mm dias, and alternative operating theater instruments seldom.We use traditional needle tube type suction pump to remove hematoma when the treatment of research hypertensive cerebral hemorrhage endoscopic surgery.For the not dark hematoma of the degree of condensing, effect is all right, but for the great majority darker hematoma of degree of condensing, it is not very desirable removing effect.Mainly be because hematoma is not easy fracture, successive hematoma plug is in needle tubing, and the suction that needs is big especially, but pressure is excessive, and the safety of operation just can't ensure.
Summary of the invention
The object of the present invention is to provide a kind of can be with less power sucking-off hematoma, again automatically in the removing body of continuous high-efficient rate the two-tube cutting scope of soft tissue attract remover.
Technical solution of the present invention:
Two-tube cutting scope attracts remover, mainly comprises cutting pipe, piston, vacuum chamber, sealing ring, back-moving spring and handle, and there is side opening cutting Guan Zaiqi suction end; The area of piston on the direction of motion is greater than the cross-sectional area of cutting pipe; The cutting pipe is connected with piston seal; Sealing ring is enclosed within on the piston; Pack into successively in the vacuum chamber back-moving spring and piston, back-moving spring can make piston move back and forth; The end of vacuum chamber is provided with valve, and this valve is connected with outside vaccum-pumping equipment; Handle is used for the stroke and convenient use of control piston.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is described in further detail:
Two-tube cutting scope attracts remover, mainly comprises cutting pipe, piston, vacuum chamber, sealing ring, back-moving spring and handle.As Fig. 1,2,3,4.Valve by vacuum chamber is connected with vaccum-pumping equipment with flexible pipe.Two-tube cutting scope attracts remover and endoscope to be used, as shown in Figure 5.The cutting pipe is inserted the instrument channel of endoscope, and be inserted in the tissue that to remove always.Open vaccum-pumping equipment.Tissue enters the cutting pipe by suction socket.Along with increasing of the tissue that enters the cutting pipe, resistance is increasing, and vacuum is also more and more higher, and tissue can't continue to enter the cutting pipe at last, and vacuum continues to raise.When vacuum reaches a certain value, the piston setting in motion.Because the area of piston on the direction of motion is greater than the cross-sectional area of cutting pipe, so the power of piston motion comes from the gas pressure that piston produces, rather than the pressure that the end produced of cutting pipe.This point is very important, and this makes moving of piston not need very high vacuum.Concrete numerical value can also be by adjusting piston the size of diameter adjust.Piston drives the motion of cutting pipe, but the instrument channel of endoscope is motionless, and the inwall of endoscopic instrument passage and relatively moving of pipe of cutting just will be organized cut-out like this, referring to Fig. 6.Gapped between the instrument channel of endoscope and the cutting pipe, air is communicated with.Under the effect of air pressure, just organizing in the cutting pipe siphoned away by vacuum equipment.Because gas circuit is connected, vacuum reduces, and under the effect of back-moving spring, piston drives the cutting pipe and resets.If can not reset fully, can piston be resetted fully.After the cutting pipe comes back in the tissue, will organize once more to suck the cutting pipe.Said process is had again.Like this, automatically and continuously tissue is cleared out of human body.Move cutting pipe or endoscope and can adjust the scope that tissue is removed.

Claims (2)

1. two-tube cutting scope attracts remover, mainly comprises cutting pipe, piston, vacuum chamber, sealing ring, back-moving spring and handle, it is characterized in that there is side opening described cutting Guan Zaiqi suction end; The area of described piston on the direction of motion is greater than the cross-sectional area of cutting pipe; The cutting pipe is connected with piston seal; Sealing ring is enclosed within on the piston; Pack into successively in the described vacuum chamber back-moving spring and piston, back-moving spring can make piston move back and forth; Described handle is used for the stroke and convenient use of control piston.
