Detailed Description

The invention will be further described with reference to the following drawings and specific embodiments:

as shown in fig. 1 and 2, the visible intracranial hematoma removing device comprises a suction tube 2, a catheter 3 and a suction barrel 1 for providing negative pressure, wherein one end of the suction tube 2 is communicated with the inside of the suction barrel 1, and the other end of the suction tube 2 is connected with the catheter 3; the suction tube 2 is provided with an expansion tube 6, the suction tube 2 at two sides of the expansion tube 6 is provided with a first one-way valve 4 and a second one-way valve 5 which can be opened towards the direction of the suction tube 1, wherein the left side of the expansion tube 6 is provided with the first one-way valve 4, the right side of the expansion tube 6 is provided with the second one-way valve 5, the first one-way valve 4 is arranged close to the expansion tube 6, so that the sucked hematoma can fall into the expansion tube 6 in time and stay in the suction tube 2 at the left side of the expansion tube 6 as little as possible, and the second one-way valve 5 can prevent the sucked hematoma from flowing back; the bottom of the expansion pipe 6 is connected with a detachable collecting bottle 7, scales 16 are arranged on the collecting bottle 7, a discharge port 17 is arranged at the bottom of the side face of the collecting bottle 7, and a valve capable of being manually opened is arranged on the discharge port 17, so that the collecting bottle 7 can conveniently discharge collected hematoma. The inside of pipe 3 is separated into along its length direction and is sucked chamber 8, observation chamber 9 and injection chamber 10, suck chamber 8 with suction tube 2 is linked together, be provided with on pipe 3 with the communicating injection mouth 11 in injection chamber 10, injection mouth 11 can inject medicine or other liquid.

As shown in fig. 1, the suction cylinder 1 includes a cylinder wall 12 and a piston 14 with a pull rod 13, a gap is formed between the piston 14 and the cylinder wall 12, a rubber cup 15 matched with the gap is arranged on an outer ring of the piston 14, and the rubber cup 15 is recessed in a direction away from the bottom surface of the cylinder wall 12. When the pull rod 13 is pulled leftwards, the volume on the right side of the piston 14 is increased, the pressure is reduced, the air pressure on the left side of the piston 14 is higher than the pressure in the cylinder wall 12, the rubber bowl 15 is tightly pressed against the cylinder wall 12, air is prevented from entering the cylinder wall 12, meanwhile, the first one-way valve 4 and the second one-way valve 5 are opened, air in the suction cylinder 1 and the catheter 3 enters the cylinder wall 12, and therefore the end of the catheter 3 is under negative pressure to suck intracranial hematoma; when the rod 13 is pushed and pulled to the right, under the closing of the first one-way valve 4, the volume on the right side of the piston 14 is reduced, the pressure is increased, and the gas in the cylinder wall 12 pushes the rubber bowl 15 open so that the piston 14 can be pushed to the bottom of the cylinder wall 12. This is circulated so that the tip of the catheter 3 is made to have a negative pressure by the suction tube 1 to thereby suck the intracranial hematoma. The hematoma sucked and led out from the catheter 3 enters the expansion tube 6 after passing through the second one-way valve 5, mainly flows into the collecting bottle 7 under the action of the expansion tube 6 with the enlarged tube diameter, cannot flow back into the catheter 3, can display the collected hematoma amount through the scale 16, and then is discharged from the collecting bottle 7 through the discharge port 17.

As shown in figure 2, in the embodiment, the pipe diameter of the catheter 3 is 5mm, the observation cavity 9 and the injection cavity 10 of the catheter 3 on the side connected with the suction pipe 2 are blind ends, the suction cavity 8 is communicated with the suction pipe 2, an L ED lamp and a camera are arranged in the observation cavity 9, the hematoma removing device further comprises an output end 18 with a visual signal and used for displaying pictures shot by the camera, the output end 18 can be in wired connection or wireless connection with the camera in the observation cavity 9, and after being injected from the injection port 11, the medicine is injected into the hematoma cavity in the cranium through the injection cavity 10 under the assistance of the output end 18 of the visual signal.

When the intracranial hematoma removing operation in the brain surgery is finished, after the hematoma is exposed to a certain degree, the end part of the catheter 3 of the visible lower intracranial hematoma removing device can be close to a hematoma cavity, under the assistance of an L ED lamp in the observation cavity 9, the output end 18 of a visible signal can display the position and the hematoma amount of the hematoma, when the hematoma needs to be removed, the pull rod 13 is pushed and pulled to enable negative pressure to be formed in the catheter 3, the hematoma can enter the suction pipe 2 through the suction cavity 8 and fall into the collecting bottle 7 from the expansion pipe 6, so that the collection of the hematoma is finished, when the hematoma in the collecting bottle 7 reaches a certain amount, the hematoma can be discharged through the discharge port 17 at the bottom of the collecting bottle 7, when the medicine needs to be injected into the hematoma cavity, the target medicine can be injected into the hematoma cavity under the assistance of the L ED lamp in the observation cavity 9, and when the hematoma amount is large and thick, the injection medicine can be injected into the hematoma.
