Retraction device for transnasal craniocerebral operation

Abstract

The invention discloses a retraction device for a transnasal craniocerebral operation, which comprises a connecting piece, a fastening block and a universal flexible shaft, the tail end of the connecting piece is connected with the fastening block, the outside of the fastening block is connected with a fastening knob and the universal flexible shaft, the outer side of the fastening knob is provided with a fastening handle, the tail end of the universal flexible shaft is connected with the retraction device, an adjusting rod is arranged in the universal flexible shaft, the tail end of the adjusting rod is connected to the retraction device, a connecting water pipe is further arranged on the outer side of the universal flexible shaft, and an adjusting knob is arranged on the surface of the fastening block. According to the retraction device for a transnasal craniocerebral operation, the retractor operation can be completed without an assistant in the using process, and the problems that an admission passage of the transnasal operation is narrow, the assistant cannot assist or the assistant carries out auxiliary operation under the view of an endoscope in a narrow space, operation risks are increased, and serious postoperative complications are caused are solved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a retractor for transnasal craniocerebral surgery. Background technique [0002] Retractors are often used to expose the required surgical area during surgery, which is convenient for exploration and operation. According to the way of use, they can be divided into hand-held retractors and automatic retractors. And there are various specifications of different shapes and sizes, and the appropriate retractor can be selected according to the operation needs. [0003] At present, the application of retractors in neurosurgery craniotomy is relatively mature, but there is still a lack of safe and easy-to-use retractor devices in transnasal craniotomy, which makes the surgical operation extremely difficult when deep normal tissues block the surgical field of view. large and risky. In the current two-person, four-handed, double-nose technique, when encountering the above situat...
