Description

Suction tube convenient for microsurgery operation
Technical Field
The utility model relates to the technical field of medical equipment, in particular to a suction tube convenient for microsurgery operation.
Background
Microsurgery is a very delicate surgical operation, the operation difficulty is high, and when the operation is performed under a microscope, the operation field must be clear, so that the smooth operation can be ensured. When tissue transplantation is carried out by microsurgery, small blood vessels of a human body are often required to be anastomosed, the diameter of a target blood vessel is about 1mm-3mm, the small blood vessel has good flexibility, but under the action of large attraction force, the endovascular membrane tissue of the blood vessel is also easily damaged, when the pressure of an aspirator exceeds the tolerance limit of the blood vessel, the blood vessel is easily sucked into an attraction pipe clamp by the aspirator to be pressed, so that the traction or the tearing and the injury of the blood vessel are caused, the operation risk is increased undoubtedly, and the operation time is prolonged.
Before completing high-quality vascular anastomosis, the precise suturing of the broken ends of the blood vessels can be realized only by keeping a clear surgical field and well exposing; in the operation, if the effusion of the operation cavity continuously exists and can not be sucked away, the original tiny operation field can be shielded certainly, and the drainage fluid has another harm that the operation cavity slowly deposits turbid floccules which are easy to adhere to the wall of the blood vessel after entering the blood vessel cavity, and even forms fatal thrombus in the later period. Microsurgery involves a suction system that is significantly different from suction tubes used in conventional general surgery, in that the suction is much less attractive than that of general surgery, but requires a continuous suction to keep the operative cavity free of blood accumulations. In addition, when the microsurgery is carried out, the microsurgery is required to be operated under a microscope, the actual operation is carried out only by allowing the operator to hold the instrument in a narrow space, the range is only about 40mm x 30mm, the operation visual field is narrow, the working plane is positioned in a deep concave cavity, the space is very limited, the body position of a patient is relatively fixed, and the operation visual field is not easy to adjust, so that the drainage rubber tube is required to be small as much as possible, the drainage rubber tube is tightly attached to the edge of the operation cavity to run, the fingers of the operator are not interfered, and the frequency of switching tools on the hand is. Moreover, microsurgery is generally time consuming, inefficient aspiration or poor drainage due to blockage tends to prolong the procedure time, aggravating the surgeon's fatigue injury.
At present, no similar products are available on the market, and in the prior art, the conventional drainage method adopted clinically adopts an ordinary surgical suction rubber tube which is placed at the lowest part of an operation cavity. But has the following disadvantages: 1. the suction force is too large, so that the blood vessel is easily sucked into the lumen or attached to the suction terminal, and the small blood vessel is damaged, thereby causing the failure of the operation; 2. the tube is too thick and occupies the position, and the terminal of the suction tube is also hard material, which interferes with the operation; 3. the suction end position is easy to move, so that ineffective suction or suction interruption is caused; 4. the thick drainage rubber tube can easily generate larger operation noise; 5. the end of the suction tube of the operation cavity is only provided with one outlet, which is easy to block, thus causing the interruption of suction; 6. rapid and high pressure pulse irrigation is difficult to realize; 7. the assistant operation is easy to be tired, and the postoperative causes the discomfort of the operation of the operator.

Preferably, the second through-hole is a plurality of, and follows the axial of soft pipe is equallyd divide into the multiunit, every group the second through-hole all follows the circumference equipartition of soft pipe, adjacent two sets of the second through-hole is followed the axial of soft pipe is the crisscross distribution of spiral of same direction, has avoided the second through-hole to be sharp issue, and when it was nearer with the intraoral tissue in art, the second through-hole on the same straight line was blocked up entirely to reduce the volume of intaking of hose, and the spiral is crisscross the second through-hole of issuing and has effectually reduced the quantity by the interior tissue of art mouth hole of blockking, the biggest volume of intaking that has kept the hose.
Preferably, one end of the soft tube, which is far away from the hard tube, is provided with a sponge sleeve, the second through hole is coated in the sponge sleeve, blood coagulated into blocks penetrates through the sponge sleeve to enter the soft tube so as to be cleaned, and the blocked blood coagulation is blocked outside the sponge sleeve, so that the situation that the blood coagulated into blocks enters the soft tube to block the soft tube is prevented, and the cleaning of bleeding wounds in an operation is influenced.
Preferably, the number of the first through holes is five, the first through holes are uniformly distributed around the circumference of the adapter tube, a plurality of bleeding areas in an operation opening are cleaned simultaneously through five hoses, and a better operation visual field is kept in the whole operation opening.
Preferably, the hard pipe is kept away from the one end of switching pipe is provided with the flow valve, through the negative pressure size in the flow valve control hose, when avoiding clearing up blood to thinner tissue, the too big tissue rupture that leads to of negative pressure.
The utility model has the advantages of it is following:
1. the soft tube is fixed in the operation cavity through the clamp, so that a doctor holding a tube hand is liberated, and the soft tube can be bent without interfering fingers of the doctor.
2. The second through hole increases the end face of the blood inlet end of the hose, so that the liquid inlet amount of the hose in unit time is increased, and the cleaning efficiency of the accumulated liquid in the operation cavity is improved.
3. The second through holes which are spirally and alternately distributed effectively reduce the number of holes blocked by tissues in the operation port, and maximally maintain the liquid inlet amount of the hose.
4. The blood which is not coagulated into a block in the operation cavity enters the hose through the sponge sleeve to be cleaned, and the blocked blood coagulation is blocked outside the sponge sleeve, so that the blood block is prevented from entering the hose to cause the blockage of the hose.
