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

[0042] see figure 1 with figure 2 , figure 1 with figure 2 It is a kind of endoscopic dura mater closure system of this embodiment, which acts on the dura mater gap 6 through the endoscope channel 7, including stuffing 1, artificial dura mater 2, compression components and medical silk thread 5, each component Pre-installed in advance, wherein, the stuffing 1 is stuffed into the dural gap 6, and the artificial dura mater 2 is placed outside the dura gap 6; the medical silk thread 5 passes through the stuffing 1, the dura gap 6, the artificial dura Membrane 2 and pressing assembly; the pressing assembly is located on the artificial dura mater 2 and is used to press the artificial dura mater 2 on the dura mater gap 6 .

[0043] The endoscopic dura mater closure system of the present embodiment is a dura mater closure system acting on the dura mater, wherein the packing 1 is a medical gelatin sponge specially used for the dura mater gap 6, and the artificial dura mater 2 is ...

Embodiment 2

[0053] see image 3 with Figure 4 , image 3 with Figure 4 It is an endoscopic dura mater closure system according to Example 2, wherein the pressing assembly includes: a support 3 and a thread joint 8, and the thread joint 8 is a movable knot composed of two strands of medical thread 5 ,Such as Figure 5 As shown, one of the medical silk threads 5 has a joint, and the other medical silk thread 5 extends into the joint. When the medical gelatin sponge and the artificial dura mater are installed in place, the joint can be pushed by tweezers to drive the support 3 along the joint. The medical silk thread 5 slides down to the artificial dura mater, and the two strands of medical silk thread 5 are tightened to press against the support 3 and the artificial dura mater. Finally, the medical silk thread 5 is cut off at the joint of the two strands of medical silk thread 5 with core scissors.

Abstract

The invention discloses an endoscopic dura mater closing system and a use method thereof. The endoscopic dura mater closing system acts on a dura mater notch (6) through an endoscope channel (7), andcomprises a filling (1), an artificial dura mater (2), a pressing assembly and a medical silk suture (5). The dura mater notch (6) is filled with the filling (1), and the artificial dura mater (2) isplaced outside the dura mater notch (6); the medical silk suture (5) penetrates through the filling (1), the dura mater notch (6), the artificial dura mater (2) and the pressing assembly in sequence;the pressing assembly is located on the artificial dura mater (2), and after the filling (1) and the artificial dura mater (2) are installed in place, the pressing assembly is pushed by tweezers to press the artificial dura mater (2) on the dura mater notch (6). A more reliable approach is provided for endoscopic dura mater closing, close fit of the filling (1) and the dura mater notch (6) is guranateed, and operation is convenient.

Description

technical field [0001] The invention relates to a surgical operation system, in particular to an endoscopic dura mater closure system and its application method. 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 is required. T...
