Problems solved by technology

The existing introducer has an outer diameter of 1.5cm, which is too large in size. The placement of such an introducer will cause greater trauma to the brain tissue
At the same time, the traditional introducer cannot use the natural gap in the brain anatomy to reach some special parts, such as the sellar region, the fourth ventricle, and the cerebellopontine angle, so as to minimize the exposure of the scalp, skull, blood vessels, nerves and Damage or removal of brain tissue

Embodiment 1

[0028] like figure 1 , figure 2 , image 3 Shown is the first embodiment of the arc introducer of the present invention, and the introducer includes a distal opening 1, an arc segment 2 assembled in more than one segment, and a funnel portion 4, an outer wing 5 for fixing, and Proximal entrance 6. Among them, the distal opening 1 can observe the situation in front, the arc section 2 is to make full use of the natural dissection interval of the brain, and the funnel-shaped entrance design of the infundibulum 4 can be conveniently and quickly inserted into soft and semi-soft microscopic devices such as suction device and fiber endoscope. invasive medical equipment; the outer wing 5 for fixation can be connected to a serpentine retractor, the proximal entrance 6 is the entrance for instrument insertion, and the arc section 2 is assembled in sections to facilitate insertion into the skull.

Embodiment 2

[0030] like Figure 4 As shown, it is the second embodiment of the present invention. The introducer includes a distal opening 1, an arc segment 2 assembled in more than one segment, an extension segment 3, a funnel portion 4, an outer wing 5 for fixing, and a proximal The end entrance 6; the distal opening 1 can observe the front structure, the arc section 2 is to make full use of the natural anatomical interval of the brain, and the extension section 3 is suitable for the operation depth from the back of the neck to the posterior fossa. The design of the infundibulum 4 facilitates insertion of medical instruments, the outer wings 5 ​​for fixing can be connected to a serpentine retractor, and the proximal entrance 6 is the entrance for inserting instruments.

[0031] For the above two embodiments, such as Figure 5 to Figure 7 As shown, according to the soft fiber endoscope 8 and the soft turning suction device 9 and the introducer section 7 in the figure, it can be known th...

Abstract

The invention discloses an arc-shaped guiding device for the minimally-invasive neuroendoscopy and a using method of the arc-shaped guiding device. The guiding device comprises an arc hard channel, and a steering soft aspirator and a soft minimally-invasive apparatus are put in the arc hard channel. The arc hard channel comprises a far-end opening, arc sections which are assembled by section, a funnel part, an outer wing and a near-end inlet which is connected with the funnel part, one ends of the arc sections are connected with the far-end opening, and the other ends of the arc sections are connected with the funnel part. According to the arc-shaped guiding device, in the using process, the spatial position of the guiding device does not need to be repeatedly adjusted, the surgical difficulty is lowered, the surgical speed is increased, iatrogenic injuries of the brain tissue, nerves, blood vessels and the like are significantly reduced, the occurrence of hematoma relapse, encephaledema, neurological function impairments and other complications in a perioperative period can be reduced, surgical injuries to the brain tissue, nerves and blood vessels are reduced to the greatest extent or removed, and the arc-shaped guiding device is suitable for endoscopic surgeries of various neurosurgery departments and otolaryngology departments.

Description

technical field [0001] The invention relates to a guide in medical equipment, in particular to a minimally invasive neuroendoscope arc guide and a method for using the same. Background technique [0002] Neurosurgery for endoscopic or microsurgery requires the use of an introducer. The existing introducer has an outer diameter of 1.5 cm, which is too large in size, and the placement of such an introducer will cause relatively large trauma to the brain tissue. At the same time, traditional guides cannot use the natural gaps in brain anatomy to reach some special parts, such as the sellar region, the fourth ventricle, and the cerebellopontine angle, so as to minimize the exposure of the scalp, skull, blood vessels, nerves and Damage or removal of brain tissue. At the same time, the neuroendoscopic minimally invasive keyhole effect currently advocated by neurosurgery requires the introducer to be moved in all directions in the deep brain tissue, which inevitably causes extrus...
