A device for dural suture in craniotomy

Abstract

The invention discloses a device for dura mater suture in craniotomy, includes a stapling device and a dura mater positioning device, the two sides of the suturing nail device are provided with dura mater positioning devices. A nail body is arranged on the suturing nail device, the inside of the nail body is provided with a battery cartridge, the battery cartridge is connected with a suturing naildevice through a nail body, A battery plate is arranged in the battery compartment, the battery panel is electrically connected with the nail body through a battery cartridge, the lower part of the nail body is rotatably provided with a hand-held rod, the hand-held rod is connected with a suturing nail device through a nail body. A link rod is arrange on that dural positioning device. A line is arrange inside that connecting rod, the line is electrically connected with the battery plate through the connecting rod. and a dura mater positioning device is arrange on the side of the suturing naildevice, the device can cooperate with the suturing nail device to assist the nail forceps, the suturing efficiency and the accuracy are improved, the structure is simple, and the device is convenientto realize.

Description

technical field [0001] The invention relates to the medical field, in particular to a device for dura mater suturing in craniotomy. In the field of [U1] Auxiliary equipment. Background technique [0002] Craniotomy is a kind of [U2] surgery, which refers to [U3] opening the patient's skull so that [U4] can be performed. [0003] [U5], during the use of the staple device because the dura mater is a thick and tough double-layer membrane. The outer layer is the periosteum on the inner surface of the skull, which is only loosely attached to the calvaria, especially in the occipital and temporal parts, which is called the periosteum layer, but it is more firmly attached to the suture of the skull and the base of the skull, making it difficult to separate. In the actual suturing process, manual operation will cause secondary pollution, and the dura mater will also slip due to its own material problems. These are problems that actually exist and need to be solved urgently. [U6] ...

AI Technical Summary

Problems solved by technology

[0004] At present, the suture of the dura mater in craniotomy mainly relies on the manual suture of the operator. Because the suture of the dura mater is required to be tight and as impermeable as possible, the number of suture needles is large, the workload is heavy, and time-consuming, especially in artificial dura mater repair. It is more significant when the suture is stretched, so it increases the risk of anesthesia for the patient, increases the exposure time of the operation area and increases the chance of infection

At the same time, because it is sutured by hand, it is greatly affected by subjective factors, and careless operation may cause damage to brain tissue, resulting in postoperative hematoma, which threatens the patient's life safety.
