Embodiment 1

[0054] refer to Figure 1 to Figure 3 , this embodiment provides an intracranial hematoma fragmentation suction device, including a sleeve 101, a negative pressure suction device 104 and a rotating device, the rotating device is installed in the sleeve 101, and the output end of the negative pressure suction device 104 is connected to the sleeve. 101 is connected, and the negative pressure suction device 104 and the rotating device are located at both ends of the sleeve 101 respectively.

[0055] When the existing suction device is working, if it encounters a relatively soft hematoma, the suction force of the suction device can slightly deform the hematoma in the process of being sucked out to pass through the suction channel, but when encountering a relatively hard hematoma, the hematoma is not easily deformed. , it will be blocked at the suction channel, so that the hematoma cannot be sucked out, and it will also affect the normal operation of the suction device. In the int...

Embodiment 2

[0064] refer to Figure 4 and Figure 5 , this embodiment also provides an intracranial hematoma fragmentation suction device. This embodiment is a further improvement on the basis of the technical solution in Embodiment 1. The technical solution described in Embodiment 1 is also applicable to this embodiment. The disclosed technical solutions in Example 1 will not be described again.

[0065] Specifically, the difference between this embodiment and Embodiment 1 is that the rotating part of the intracranial hematoma fragmentation aspirator provided in this embodiment includes a helical shaft 106, and a groove 107 is provided on the helical shaft 106, and the groove 107 is along the helical shaft. The circumferential and axial directions of 106 are helical. In this way, the hematoma can be sucked into the negative pressure suction device 104 along the groove 107 on the helical shaft 106 .

[0066] The groove 107 extends along the helical shaft 106 and forms a slice 108 on th...

Embodiment 3

[0068] refer to Image 6 , this embodiment also provides an intracranial hematoma fragmentation suction device. This embodiment is a further improvement on the basis of the technical solution in Embodiment 1. The technical solution described in Embodiment 1 is also applicable to this embodiment. The disclosed technical solutions in Example 1 will not be described again.

[0069] Specifically, the difference between this embodiment and Embodiment 1 is that the rotating part of the intracranial hematoma crushing suction device provided in this embodiment includes a hematoma crushing device 109 and an end that is used to control the hematoma crushing device 109 away from the flexible shaft 103 is opened. Or the controller in the closed state, the hematoma breaking device 109 is installed on the flexible shaft 103, the hematoma breaking device 109 at the front end can be controlled by the controller at the back end to be in an open or closed state, and people can use the controlle...

Abstract

The invention provides an intracranial hematoma breaking aspirator and an intracranial hematoma breaking vacuum aspiration device and belongs to the field of medical equipment. The intracranial hematoma breaking aspirator comprises a sleeve, a vacuum aspiration device and a rotating device, wherein the rotating device is arranged in the sleeve; an output end of the vacuum aspiration device is connected with the sleeve; the vacuum aspiration device and the rotating device are respectively located at the two ends of the sleeve. The intracranial hematoma breaking vacuum aspiration device comprises an externally connected suction device and the intracranial hematoma breaking aspirator, wherein the externally connected suction device is connected with the vacuum aspiration device. According to the intracranial hematoma breaking aspirator provided by the invention, the rotating device is arranged in the sleeve; after the sleeve is close to a hematoma, the rotating device is inserted into the hematoma and is rotated; the shearing force of the rotating device is utilized to break the hematoma; after the hematoma is broken, the vacuum aspiration device can be used for conveniently sucking the hematoma fragments.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an intracranial hematoma fragmentation suction device and an intracranial hematoma fragmentation negative pressure suction device. Background technique [0002] Intracerebral hemorrhage refers to hemorrhage caused by rupture of blood vessels in the non-traumatic brain parenchyma, accounting for 20% to 30% of all strokes, with an acute mortality rate of 30% to 40%. Intracranial hematoma is formed when the blood vessels in the brain or between the brain and the skull are ruptured due to trauma and other reasons, and blood collects in the brain or between the brain and the skull and compresses the brain tissue. Intracranial hematoma is a common and serious secondary lesion in traumatic brain injury. The incidence is about 10% of closed craniocerebral injury and 40% to 50% of severe craniocerebral injury. [0003] The inventor found in the research that the existing suction devic...
