Problems solved by technology

Although the above method is simple, there are many problems, including: 1. The effect of packing is inaccurate. If the gelatin sponge packed is too loose, it may cause recurrence of cerebrospinal fluid after surgery; 2. When it is combined with glue, artificially designed packing is required. The operation is more complicated; 3. If fat tamponade is used, it needs to increase the damage of other parts
At present, there is no professional tool on the market for filling the gap in the dura mater

Embodiment 1

[0048] figure 1It is a structural cross-sectional schematic view of Embodiment 1 of the dura mater opening closure device, including an inner support component 1 , an outer compression component 2 , a connection component 3 and a packaging component 4 . Package assembly 4 comprises pipeline 5, and internal support assembly 1, connection assembly 3 and outer compression assembly 2 are placed successively in the pipeline, and interior support assembly 1 and outer compression assembly 2 are connected by connection assembly 3. Wherein, the inner support component 1 is a gelatin sponge, and the gelatin sponge is compressed to the first structure in advance, such as figure 1 As shown, to ensure that the whole can be packed in the packaging assembly 4, and can be pushed in the dura mater opening during operation, the circumference of the gelatin sponge in the first structural state is less than the circumference of the dura mater opening. The outer pressing assembly 2 is a memory al...

Embodiment 2

[0055] Image 6 It is a structural cross-sectional schematic view of Embodiment 2 of the dura mater opening closing device, including an inner support component 1 , an outer compression component 2 , a connection component 3 , a packaging component 4 and a push rod 6 . Package assembly 4 comprises pipeline 5, and internal support assembly 1, connection assembly 3 and outer compression assembly 2 are placed successively in the pipeline, and interior support assembly 1 and outer compression assembly 2 are connected by connection assembly 3. Wherein, the inner support component 1 is a composite material composed of gelatin sponge 1-1 and dura mater patches (1-2a and 1-2b), and the two sides of gelatin sponge 1-1 are respectively arranged with dura mater patches 1-2a and 1 -2b, Since the dura patch is not an expansive material, pre-compress the gelatin sponge 1-1 to the first structure, such as Image 6 As shown, to ensure that the whole can be packed in the packaging assembly 4,...

Abstract

A dura mater opening closing device comprises an inner supporting assembly, an outer pressing assembly, a connecting assembly and a packaging assembly, wherein the packaging assembly comprises a pipeline structure, and the inner supporting assembly, the connecting assembly and the outer pressing assembly are sequentially arranged in the pipeline; and the inner supporting assembly and the outer pressing assembly are connected through the connecting assembly. The dura mater opening closing device is simple in structure and convenient to operate, key assemblies are pre-installed in the packagingassembly, taking and using are convenient, and time and labor are saved.

Description

technical field [0001] The invention relates to a surgical operation device, in particular to a dural opening closing device, which belongs to the field of medical instruments. Background technique [0002] In neurosurgery, it is generally necessary to suture anatomical reduction for dura mater injury, such as dura mater and dura mater injury, but when operating in endoscopy, due to the narrow space of endoscope, it is too difficult for doctors to suture manually, so most doctors The method of filling materials for repair generally includes the following three types: 1. Simply use gelatin sponge for filling; 2. Combine medical glue and gelatin sponge for filling; 3. Use human body fat for filling. Although the above method is simple, there are many problems, including: 1. The effect of packing is inaccurate. If the gelatin sponge packed is too loose, it may cause recurrence of cerebrospinal fluid after surgery; 2. When it is combined with glue, artificially designed packing ...
