Problems solved by technology

[0007] At present, when the keyhole surgery in neurosurgery or the access device in minimally invasive surgery is used, the intervention method is to first expand a small channel and then intervene from the outside, or directly intervene without expansion. The diameter of the instrument channel is generally relatively large, and it is easy to cause crush damage to the brain tissue near the approach during the intervention process; moreover, the traditional channel is made of a hard tubular body, which will cause the pressure of the brain tissue around the approach to rise due to excessive support, resulting in Brain tissue damage or complications, need a flexible channel to solve this problem
Traditional stomas have disadvantages for demanding procedures

Embodiment 1

[0039] Such as figure 1 , figure 2 As shown, the present invention provides a plastic multi-functional craniotomy device, including a suction stripping device 1 with a suction channel 2 in the middle, and a concave ring 3 arranged on the tube wall of the suction stripping device 1 , the introduction isolator 4 sleeved on the concave ring 3, the loading sheath 5 sleeved on the tube wall of the suction stripping device 1 and constraining the introduction isolator 4 in the concave ring 3, and sleeved on the On the concave ring 3 and inserted in the loading sheath 5, the distal end abuts against the isolator pushing rod 6 at the end of the introduction isolator 4. The introduction isolator 4 is a kind of restrained deformation and unconstrained recovery expansion to a predetermined shape. device.

[0040]The isolator pushing rod 6 is arranged at the proximal end of the loading sheath 5, and has the same outer diameter as the inner diameter of the loading sheath 5, and can be pu...

Embodiment 2

[0049] Such as image 3 , Figure 4 , Figure 5 As shown, the difference between Example 2 and Embodiment 1 is the structure of the attractable peeling device 1. The attractable peeling device 1 in this embodiment includes an inner tube 7 of the aspirator, which is sleeved on the outside of the inner tube 7 of the aspirator. There is an aspirator outer tube 14, and there is a gap between the inner wall of the aspirator outer tube 14 and the outer wall of the aspirator inner tube 7. The gap is the filling channel 16, and the distal end of the aspirator outer tube 14 is screwed to a far end. The end guide head 8 is provided with a vent hole 15 on the distal guide head 8, and the vent hole 15 communicates with the filling channel 16, and an expansion balloon 17 connected with the vent hole 15 is fixedly connected to the distal guide head 8. The expansion balloon 17 can be inlaid and bound or bonded to the distal end of the suction stripper 6-1. The expansion balloon 17 can be f...

Abstract

The invention discloses a shapable multifunctional brain zaotong device. The device comprises an attractable stripping device, a concave ring, an import isolator, a loading sheath tube and an isolatorpushing rod, wherein the middle of the attractable stripping device is provided with an attracting passage, the concave ring is arranged on the tube wall of the attractable stripping device; the import isolator sleeves the concave ring; the loading sheath tube sleeves the tube wall of the attractable stripping device and restrain the import isolator in the concave ring; the isolator pushing rod sleeves the concave ring and is interspersed in the loading sheath tube, and the far end abuts the tail end of the import isolator. The shapable multifunctional brain zaotong device has the advantagesthat by utilizing different functions, a shapable flexible isolator is adopted during the operation, the pressure of intracranial brain tissue after release can be naturally balanced so as to preventthe increase of brain tissue pressure around an approach caused by the excessive support of a hard channel, after the isolator pushing rod pushes the import isolator into a lesion area, the force is applied to the import isolator to prevent the import isolator from being squeezed out of a preset position.

Description

technical field [0001] The invention relates to the field of medical orthopedic devices, in particular to a shapeable multifunctional craniosynthetic device. Background technique [0002] The keyhole technique is a medical technique used in minimally invasive surgery for diseases such as intracranial aneurysms. The development of keyhole technology in our country is relatively late. In the past ten years, there has been almost no continuous progress and clinical application of keyhole technology. With the development of medical technology and the continuous improvement of medical equipment, especially the advent of medical imaging and endoscopic equipment in recent years, the development of micro-neurosurgery technology has been promoted, and more and more neurosurgeries have begun to explore cranial neurosurgery Brain minimally invasive surgery. Through the cooperation of precision imaging equipment and microneurosurgery, and the combination of endoscopic surgery and micr...
