Embodiment Construction

[0046] Below in conjunction with accompanying drawing, structural principle and working principle of the present invention are specifically described:

[0047] The scissors or pliers in the prior art have only one angle (if the scissors are regarded as the x-y plane, then all the rotation axes are perpendicular to the plane and can be regarded as the z-axis, and the scissors can be tilted along the z-axis to form a certain angle with the y-plane. Angle.) This scissors or forceps can be used for general laryngeal microsurgery, but once the lesion is in a specific position (for example: the lesion is located in the front of the laryngeal chamber), it is impossible to cut it down. The present invention aims at this situation. While retaining the tilting angle and direction of the original z-axis, the function of rotating along the z-axis is added to facilitate the pruning of lesions at this specific position.

[0048] see figure 1 and figure 2 , figure 1 It is a schematic dia...

Abstract

The invention discloses a multi-angle throat surgical instrument comprising an operating unit and a control unit which are connected mutually, wherein the operating unit comprises a fixed operating member and a movable operating member which are mutually hinged at a connecting point; the control unit comprises a bracket as well as a fixed control mechanism and a movable control mechanism which are installed on the bracket; the fixed control mechanism is connected with the fixed operating member; the movable control mechanism is connected with the movable operating member; the control unit also comprises an angle adjusting unit which is respectively connected with the fixed control mechanism and the movable control mechanism. The multi-angle throat surgical instrument has the advantages of overcoming the defect of limited surgical operation due to a single angle of a throat micro surgery instrument in the prior art, directly treating pathological changes at the front end of the throat through a surgery, widening the treating range of pathological changes of ventriculus laryngis through surgical treatment, shortening the surgical treatment time and relieving the pain of patients.

Description

technical field [0001] The invention relates to a surgical instrument, in particular to an angle-adjustable multi-angle laryngeal surgical instrument suitable for surgical treatment of laryngeal frontal lesions. Background technique [0002] With the popularization of supporting laryngoscope technology, minimally invasive laryngeal surgery becomes possible, especially the video endoscopic technology gradually developed in recent years, combined with supporting laryngoscope, more significantly improves the surgical accuracy. However, in clinical work, some patients with lesions at the front of the larynx often appear. Due to reasons such as body structure, cervical spine diseases, and anesthesia, it is difficult to expose the lesion tissue under the support laryngoscope. Only by applying some special angles (such as 45°) , 70°) endoscope can help the operator to clearly observe the diseased tissue, but due to the limitation of the operating space of the supporting laryngoscop...
