Detailed Description

The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

A tissue extraction device for tumor examination, as shown in figures 1 to 5, comprises a hollow cavity 1, a collection cavity 2, a lower slide block 3, an upper slide block 4, an operating rod 5, a push block 6, a sealing gasket 7, a catheter 8 and an extraction needle 9.

As shown in fig. 1 to 3, the collection chamber 2 is movably disposed below the hollow chamber 1. Here, the hollow cavity 1 may be a cylindrical shape, in which case the collection cavity 2 is also a cylindrical shape, and the hollow cavity 1 is spirally disposed in the collection cavity 2. Or the hollow cavity 1 is a cuboid, the collecting cavity 2 is also a cuboid, and the hollow cavity 1 is buckled in the collecting cavity 2 at the moment. In view of the sealing between the hollow chamber 1 and the collection chamber 2, a sealing material such as a gasket may be suitably used. To facilitate the observation of the interior of the device, the hollow cavity 1 and/or the collection chamber 2 are made of transparent material, such as glass.

The lower sliding block 3 is arranged in the hollow cavity 1 in a sliding mode, and the upper sliding block 4 is arranged in the hollow cavity 1 in a sliding mode. In order to ensure the sealing performance of the lower sliding block 3 and the upper sliding block 4 in the sliding process in the hollow cavity 1, a sealing rubber sleeve 10 is sleeved on the outer side of the lower sliding block 3 or the sealing rubber sleeves 10 are sleeved on the outer sides of the lower sliding block 3 and the upper sliding block 4, wherein the sealing rubber sleeve 10 is a conventional technology. The upper slider 4 is connected with the lower slider 3, which can be connected up and down by screws 11 or other connecting members.

Referring to fig. 1 to 4, the lower slider 3 is provided with an upper opening groove, the bottom of the upper opening groove is provided with a lower chute 31 and lower vent holes 32, the lower vent holes 32 are arranged around the lower chute 31, and preferably, the lower vent holes 32 are uniformly distributed around the lower chute 31. Referring to fig. 1 to 3 and 5, the upper slider 4 is provided with a lower open groove corresponding to the upper open groove, and the top of the lower open groove is provided with an upper vent hole 41 and an upper slide groove 42 communicating with the upper open groove. When the lower slider 3 and the upper slider 4 are arranged in the hollow cavity 1, outside air is communicated with the collection cavity 2 through the upper vent hole 41, the lower open groove, the upper open groove and the lower vent hole 32.

The operating rod 5 is movably arranged in the upper sliding groove 42, and the push block 6 is fixedly arranged at the bottom end of the operating rod 5. When the operating rod 5 pushes downwards, the push block 6 abuts against the lower chute 31, and then the lower slider 3 slides downwards, wherein when the push block 6 abuts against the lower chute 31, the push block 6 does not seal the lower vent hole 32, and air in the hollow cavity 1 is discharged. For convenient operation, a handle is arranged above the operating rod 5. The sealing gasket 7 is sleeved at the top end of the push block 6. Preferably, the sealing gasket 7 is in a circular truncated cone shape, rubber can be adopted, and the sealing gasket 7 can better seal the lower opening groove. When the operating rod 5 is pushed upwards, the sealing gasket 7 seals the upper opening groove and the upper vent hole 41, the upper sliding block 4 slides upwards, and the air pressure in the hollow cavity 1 is reduced.

One end of the duct 8 is communicated with the hollow cavity 1, and the extraction needle 9 is arranged at the other end of the duct 8. Regarding the way the conduit 8 communicates with the hollow cavity 1, if the hollow cavity 1 is made of glass, the conduit 8 is sleeved at one opening of the hollow cavity 1, similar to the way the conduit is sleeved at one opening of the fractionating flask. Further, a flow regulator 12 may be provided in the conduit 8, and the flow regulator 12 may be used for intravenous drip.

In use, the operating rod 5 is pushed downwards, causing the lower slider 3 to move downwards, the lower slider 3 being positioned above the mouth of the conduit 8 and not entering the collection chamber 2. Puncture through extraction syringe needle 9, make it enter into the tumour, open flow regulator 12, upwards pull operating lever 5, form the negative pressure in cavity 1 and the collection chamber 2, the hydrops of patient's flesh wound department is inhaled to collection chamber 2 in. When the amount of the liquid to be sucked is insufficient, the flow regulator 12 is closed, the operating rod 5 is pushed downwards, the air in the hollow cavity 1 and the air in the collecting cavity 2 are discharged from the vent hole 41, then the flow regulator 12 is opened, the operating rod 5 is continuously pulled upwards, and the liquid accumulated at the wound of the body of the patient is sucked into the collecting cavity 2 until the amount of the liquid to be sucked reaches the requirement. Finally, the extraction needle 9 is pulled out of the patient's body, completing the sampling process.

It should be understood that the above embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the same, and it is obvious for those skilled in the art that the technical solutions described in the above embodiments can be modified or some technical features can be replaced equivalently as long as there is no structural conflict; and all such modifications and alterations should fall within the scope of the appended claims.
