Arc-shaped scissors for clover dura stitching method

Abstract

The invention discloses arc-shaped scissors for a clover dura stitching method, and relates to the technical field of medical instruments. Comprising a right handle and a left handle, finger rings are fixedly connected to the lower ends of the left handle and the right handle, the upper sides of the left handle and the right handle are overlapped, a rotating shaft is rotatably connected to the overlapped position of the upper ends of the left handle and the right handle, arc blades are fixedly connected to the upper ends of the left handle and the right handle, and the arc blades are bent in the axial direction of the rotating shaft; by means of the mode that the arc blade is cut on the dura mater in an arc mode, in the microvascular decompression operation, the surface tension of the dura mater on the craniocerebral spherical dura mater is smaller than that of the dura mater cut in a linear mode and an arc mode, suturing of the dura mater in the later stage of the operation is facilitated, exposure of the operation field is increased, and the dura mater is trimmed at a time through the arc blade in the using process.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an arc-shaped scissors for dural clover suture. Background technique [0002] Microvascular decompression is the preferred surgical method for the treatment of cranial nerve disorders based on vascular compression theory, such as hemifacial spasm, trigeminal neuralgia, and glossopharyngeal neuralgia. content. Since Jannetta pioneered microvascular decompression in 1966, it has been rapidly promoted in clinic for its safety and efficacy in the treatment of cranial nerve diseases. [0003] Hemifacial spasm is a common clinical functional disease, although it is not life-threatening, it can seriously reduce the quality of life of patients. It starts around the eye and then expands to other muscles innervated by the facial nerve, with the most obvious twitching of the corner of the mouth muscle. In severe cases, it can involve the ipsilateral neck and even the chest muscles...

AI Technical Summary

Problems solved by technology

[0005] To sum up, the current microvascular decompression has the following technical problems: the cranial dura mater needs to be cut during the operation, and the classic dura mater cutting method is an inverted T-shaped, Y-shaped, or cross-shaped cut. The traditional cutting method is to use surgical scissors to cut in a straight line. Since the brain is spherical, the exposure range of the field of view after cutting is small. The surface tension of the dura mater itself is not conducive to suturing; due to the small exposure range of the visual field after the dura mater is cut, the intracranial surgery takes a long time, and postoperative complications such as intracranial infection, cerebrospinal fluid leakage, and hearing loss may occur; Existing surgical scissors are all cut in a straight line. When cutting in an arc, the operator needs to constantly adjust and trim many times to achieve the desired effect. Using the arc-shaped trimming method, but did not increase the exposed area, did not achieve the arc-shaped cutting to reduce the surface tension, and during the trimming process, the next trimming direction is not at the farthest end of the last trimming, resulting in Multiple redundant incisions, the cutting edges are not neat, which is not conducive to later suturing
