When diseases or lesions in the cranioconjunctival junction area cause high spinal cord and brainstem compression, decompression or internal fixation surgery is often performed anteriorly, and oral or nasal access is one of the commonly used surgical approaches. Since the nasal cavity cannot accommodate too many instruments, special instruments must be designed to perform the procedure, which is quite different from the conventional open surgery. After decompression is finished, the closing of the incision is a key technical problem, and no special suturing instrument for the nasal endoscope is required in the markets at home and abroad. Therefore, the current surgical method generally adopts the U-shaped reverse of the mucosal flap, and the treatment is carried out by using a method of biological protein glue after the operation is finished. The treatment method can not close the surgical wound surface tightly, and once the conditions of dura mater damage, cerebrospinal fluid leakage and the like occur in the operation, intracranial infection is easy to occur, and the death of a patient is caused.

In open surgery, when suturing, two instruments are generally required to cooperate to complete the suturing operation of tissues such as mucosa or skin, and no device for realizing the suturing by a single instrument exists. When the auxiliary operation is performed through the nasal endoscope, only one operable instrument can be generally placed in each nostril, because the endoscope occupies the nostril at one side, two conventional surgical instruments cannot be simultaneously placed in the nasal cavity to complete the suture of the mucous membrane, and only the nostril at one side can be used by the suture instrument. To perform the operation of suturing the mucosa in the nostril, a device which can complete the suturing action by a single instrument must be developed.
