Description
Technical Field
The utility model belongs to the technical field of medical instrument, concretely relates to is a bilateral nostril retractor of butterfly approach.
Background
The approach via the nasal butterfly has been developed for a century. Harvey cushing (Harvey cushing) played an important role in its popularity in intranasal surgery, since he was the surgeon of Schloffer and Halstead at the time. In the early stages of skull surgery, cushing was actually placed by sphenoid surgery to explore the margins of brain surgery. Through the improvement of operation technology and instruments, the transnasal butterfly approach under the neuroendoscope becomes an important operation mode of the neurosurgery at present.
Over the 20 years, with the development of medical science and technology and related subject technology, the transnasal neuroendoscopic surgery has progressed at a dramatic rate and reached a new level. Compared with the traditional nasal butterfly operation, the neuroendoscope nasal butterfly operation is a conceptual innovation, and has various incomparable advantages, such as closer approach to an operation target, avoidance of traction and damage to brain tissues, reduction of postoperative pain, fast recovery, fewer complications and the like. 95% of saddle region lesions can be removed by conventional transsphenoidal approach surgery. In recent years, endoscopic indications have been expanded to lesions in the entire cranial base midline region, i.e., the anterior to frontal sinus, and posterior to the dentate process region, where it was previously thought impossible to remove tumors and other lesions by endoscopic surgery, and it is now possible to obtain removal by endoscopic dilation through the nasal route. Meanwhile, the development of the skull base reconstruction technology effectively solves the problem of cerebrospinal fluid leakage which always troubles neurosurgeons.
The important difference and advantage of endoscopic transnasal sphenoidal approach surgery from traditional transsphenoidal approach microsurgery is that the trauma is small, and the normal structure of the nasal cavity-sphenoidal sinus can be protected to the maximum extent. The operation mainly utilizes the natural space of the nasal cavity to form an operation channel, and the optical illumination characteristic of the endoscope and the angle of the endoscope are convenient for close observation, so that the observation range in the operation is increased, important anatomical signs can be clearly distinguished, the operation target can be clearly displayed in the operation, lesion tissues or tumors can be furthest removed, normal tissues can be protected, side injury is reduced, and the operation quality is improved. Because the operation wound is little, stanchs thoroughly, need not pack the nasal cavity after the operation, and patient after the operation does not have the uncomfortable sense that the nasal cavity was packed, and patient's postoperative reaction is light, resumes soon, and the time of being in hospital is short, and the activity of can going to the land in 1 ~ 2 days after the operation, just can discharge from the hospital in 3 ~ 5 days.
With the development of clinical medical technology, four hands of two people become the mainstream of the operation of nasal butterfly through the operation of double nostrils, because in the art neural scope, aspirator, get the apparatus such as tumour pincers and need go in and out the nasal cavity repeatedly, can't avoid the damage to the nasal cavity mucosa, the nasal mucosa also can make dirty neural scope camera lens simultaneously, lead to the art wild, especially to the patient that the turbinate, in the art, must use the nasal cavity retractor in order to increase the field of vision, but at present only there is the retractor of single nostril, if during the operation of bilateral nasal cavity, need use two retractors, or one side is used, the opposite side does not use, still does not have a retractor that can prop open nasal cavity both sides simultaneously.
The utility model provides a two side nostril retractors of the butterfly approach to the above-mentioned problem.
