Problems solved by technology

[0002] For the minimally invasive debridement of cerebral hemorrhage, all the instruments used now have the problem of blind puncture and blind aspiration, that is, the doctor cannot see the puncture process and the specific situation of the patient's intracranial hematoma, and does not know the patient's intracranial pressure and its changes. The intracranial hematoma is suctioned according to the principle of equivalent replacement, so that the intracranial pressure of the patient is relatively stable. The progress of hematoma removal is judged by the state of the blood pumped out, and there is no more specific change in the state of different hematomas. Treat differently, increase the risk of rebleeding during treatment

Embodiment 1

[0072] The needle-shaped drill punctures the patient's skull along the set puncture point and puncture direction. After drilling through the skull and dura mater, the length of the fixed channel of the needle-shaped drill acts as a limiter. Cut off the fixing clip and pull out the drill. The fixation patch can be made of antibacterial material to prevent wound infection and be installed on the skull puncture fixation channel and fixed with the scalp. At this time, the left and right sides of the skull puncture fixation channel are self-locked by the bone holes, and the upper and lower sides are fixed by the fixation patch.

[0073] Insert the endoscope into the observation channel of the visual cleaning strip, remove the fixing seat on the body of the rigid multi-channel intracranial hematoma evacuator, and insert the visual cleaning strip with the endoscope into the body of the rigid multi-channel intracranial hematoma evacuation device In the channel, it is composed of an ent...

Embodiment 2

[0078] Rigid multi-channel intracranial hematoma evacuator or soft multi-channel intracranial hematoma evacuator can also be used alone, the method is as follows:

[0079] Use a craniotomy drill to drill holes along the set puncture point and puncture direction, stop drilling after penetrating the skull, make a cross-cut dura mater, and place the rigid multi-channel intracranial hematoma evacuator or soft multi-channel intracranial hematoma evacuator along the After the hematoma is punctured through the bone hole, it is fixed with adhesive tape or suture, and the rest of the operations and usage methods are the same as those in Example 1, and will not be repeated here.

[0080] To sum up, with the help of the above technical solution of the present invention, on the basis of ordinary puncture instruments, channels for intracranial pressure probes and endoscopes are newly added, allowing doctors to add intracranial pressure probes and endoscopes in the established surgical chann...

Abstract

The invention discloses a multi-channel puncture needle for intracranial hematoma. The multi-channel puncture needle for intracranial hematoma comprises a rigid multi-channel intracranial hematoma remover body, a soft multi-channel intracranial hematoma remover body, a skull puncture fixing channel and a needle-shaped drill bit, wherein a sleeve is arranged on a through hole in the middle part ofthe rigid multi-channel intracranial hematoma remover body, the sleeve is formed by sleeving multiple layers of pipes, at least one fluid channel is formed in the side edge of a cylinder of the rigidmulti-channel intracranial hematoma remover body, and fluid inlets in one-to-one correspondence with the fluid channels of the rigid multi-channel intracranial hematoma remover body are formed in thesleeve. With the multi-channel puncture needle for intracranial hematoma, a doctor can see the state of intracranial hematoma in the process of treatment, the state of a patient in an operation can bebetter controlled, and a corresponding treatment means can be provided; two independent liquid inlet channels are designed in the wall of the sleeve, and different flushing modes can be selected according to different states of hematoma, so treatment means are enriched; and hematoma removal can be carried out through a hose in the flexible multi-channel intracranial hematoma remover body according to specific conditions.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a multi-channel intracranial hematoma puncture needle. Background technique [0002] For the minimally invasive debridement of cerebral hemorrhage, all the instruments used now have the problem of blind puncture and blind pumping, that is, the doctor cannot see the puncture process and the specific situation of the patient's intracranial hematoma, and does not know the patient's intracranial pressure and its changes. The intracranial hematoma is suctioned according to the principle of equivalent replacement, so that the intracranial pressure of the patient is relatively stable. The progress of hematoma removal is judged by the state of the blood pumped out, and there is no more specific change in the state of different hematomas. Treat them differently, increasing the risk of rebleeding during treatment. [0003] Aiming at the problems in the related technologies, no eff...
