Background

At present, a suction tube is often used for sucking blood or effusion intracranial exuded by a patient during neurosurgery so as to maintain a clean operation visual field and search a bleeding point. Because the brain tissue is soft and has certain fluidity, if the blood is directly sucked by using the suction tube, the brain tissue and the cranial nerves are easy to be damaged. Therefore, at present, the mouth of the suction tube is usually abutted to the brain cotton sheet to absorb blood in neurosurgery, but the brain cotton sheet and the suction tube are not fixed, and the suction tube is easily separated from the brain cotton sheet, so that brain tissue is damaged. And the brain cotton sheet has poor permeability, can adsorb liquid blood, but can not adsorb coagulated blood clots.

1. At present, when the brain tissue is subjected to bleeding operation, the commonly used handheld rigid suction tube is easy to contused the brain tissue, when the blood is sucked, other instruments in the hand are required to be replaced or an assistant participates in the operation, the operation time is prolonged, and the space of an operation area is reduced due to the addition of the instruments. The effect of the operation is affected;

2. the head end of the traditional handheld hard aspirator is made of an iron material, is rough and is easy to damage brain tissues; the existing simple hose is easy to stab brain tissue;

3. the side hole of the traditional aspirator is manually blocked by a person, when the side hole is completely blocked, the suction force is too large, and when blood and other liquid are sucked in brain tissue, the adjacent brain tissue and small blood vessels are possibly damaged, so that the risks of brain tissue function damage, bleeding and the like are increased.

FIG. 3 is a cross-sectional view of the head end of the first suction leg of the present invention;

in the figure: the device comprises a suction header pipe 1, a three-way joint 2, a first suction branch pipe 3, a second suction branch pipe 4, a hole 5, a filter head 6, an anti-slip ring 7, a stop valve 8, a negative pressure adjusting hole 9 and a negative pressure adjusting sheet 10.

Detailed Description

The utility model will be further described with reference to the accompanying drawings in which:

as shown in figures 1-3, a neurosurgery that can reduce damage is with inhaling pipe, including attracting house steward 1, three way connection 2, first suction branch pipe 3 and second suction branch pipe 4, attracts house steward 1, first suction branch pipe 3 and second suction branch pipe 4 to be flexible silica gel hose material, conveniently aims at the bleeding point with the head end, the operation of being convenient for. Three ports of the three-way joint 2 form an outlet and two inlets respectively, the tail end of the suction main pipe 1 is connected with the outlet of the three-way joint 2, and the head end of the suction main pipe is connected with the negative pressure generating device. The tail ends of the first suction branch pipe 3 and the second suction branch pipe 4 are respectively connected with two inlets of the three-way joint 2.

Holes 5 are densely distributed on the pipe wall at the front end of the first suction branch pipe 3, a filter head 6 is sleeved at the holes 5, and the filter head 6 completely wraps the area with the holes 5. The filter head 6 is sleeve-shaped, and the inner diameter of the filter head 6 is not larger than the outer diameter of the first suction branch pipe 3, so that the filter head 6 is conveniently connected to the first suction branch pipe 3. The filter head 6 is made of porous material, preferably filter cloth or brain cotton sheet material, so that blood can conveniently enter the first suction branch pipe 3 through the filter head 6. For the fastness that improves filter head 6, prevent that filter head 6 from droing from first

suction branch pipe

3, 6 tail end departments of filter head are equipped with annular antiskid circle 7, and antiskid circle 7 is fixed in on the inner wall of filter head 6, and antiskid circle 7 can increase the static friction force between filter head 6 and the first suction branch pipe 3. A stop valve 8 is arranged at the front end of the second suction branch pipe 4.

The filter head 6 can effectively suck out blood and the like in the operative field during suction, the material is the same as that of the brain cotton sheet, and meanwhile, compression hemostasis can be carried out, thereby avoiding damaging brain tissues and peripheral blood vessels.

In order to adjust the magnitude of the negative pressure at the head end of the first suction branch pipe 3, a negative pressure adjusting hole 9 is formed in the pipe wall of the middle part of the first suction branch pipe 3, and the negative pressure adjusting hole 9 penetrates through the pipe wall; the negative pressure adjusting hole 9 is connected with an elastic negative pressure adjusting sheet 10, and the size of the negative pressure adjusting hole 9 can be changed by pressing the negative pressure adjusting sheet 10, so that the negative pressure at the head end of the first suction branch pipe 3 is adjusted.

The using method of the utility model is as follows:

when the blood sucking device is used, the stop valve 8 is closed, and the head end of the first suction branch pipe 3 is placed at a bleeding point to suck leaked blood. The negative pressure generating device generates negative pressure to suck blood into the first suction branch pipe 3, and the brain tissue can be prevented from being damaged due to the protection effect of the filter head 6. When partial blood clots appear, because the blood clots can't pass through filter head 6, open stop valve 8 this moment, place second suction branch pipe 4 in blood clots department, slowly inhale second suction branch pipe 4 with the blood clots after, remove second suction branch pipe 4 and close stop valve 8, so the operation can furthest reduce the injury to the brain tissue.

The utility model has the advantages that the operation can be still finished under the condition that the operation space is relatively narrow and the assistant can not be effectively matched, thereby reducing the related risks of hemorrhage in the operation and brain tissue injury. During operation, after the side hole of the suction apparatus is blocked, an operator can place the suction tube in an operation field, and the negative pressure adjusting sheet replaces an assistant to manually press the suction tube, so that the labor is saved. Meanwhile, the filter head wrapped outside the negative pressure regulating sheet can effectively prevent the blockage of the tube cavity, and simultaneously achieve the effect of compression hemostasis, thereby avoiding damaging adjacent tissues and blood vessels due to improper operation.

It should be noted that the above are only some embodiments of the present invention, and it should be noted that, for those skilled in the art, many modifications and substitutions can be made without departing from the technical principle of the present invention, and these modifications and substitutions should also be regarded as the protection scope of the present invention.
