Description
Technical Field
The utility model relates to the technical field of medical appliances, in particular to a vertebral lamina rongeur with a suction device function.
Background
The vertebral plate rongeur is a surgical instrument for biting a dead bone or trimming a bone stump in an operation, and the aspirator is an auxiliary instrument for sucking bleeding, exudates and the like in the operation. In the operation process, bleeding is more, the operation visual field is affected, and the operation is often required to be conducted by a hand-held aspirator of an operator, the operation is conducted by the other hand-held vertebral plate rongeur by two hands, or the operation is conducted by the hand-held aspirator of an assistant. However, in the case that the surgical field stenosis cannot be simultaneously placed into the laminar rongeur and the aspirator, the operator can only first use the aspirator to aspirate, quickly withdraw the aspirator after clearly exposing the surgical area, and place the laminar rongeur for operation. However, if the bleeding or the leakage speed of cerebrospinal fluid in the operation area is high at this time, when the vertebral plate rongeur is placed, the operation field is shielded by blood or cerebrospinal fluid, so that the field of view is unclear, the operation cannot be smoothly performed, the operation is difficult, and the operation progress is affected. The following are illustrated:
when performing transnasal endoscopic odontoid resection, since the nasal cavity itself has a limited space, it is necessary to insert an endoscope, a suction device and a laminar rongeur into a narrow nasal cavity space to bite bone tissue. During operation, the operation is often influenced by collision of instruments, or the operation cannot be performed due to the shielding of the endoscope view by the surgical instruments. If one instrument (aspirator) is reduced, the surgical field of view is shielded by bleeding, so that accurate biting is not realized, and even nerve vessel accidental injury is caused.
The utility model patent CN204246240U discloses a vertebral plate rongeur with a suction device function, which comprises a fixed handle, a movable handle, a forceps body and a cutting forceps body, wherein a sheath tube with two open ends is arranged in the forceps body, the suction device is inserted into the sheath tube, an electrocautery device is embedded into the upper surface of a forceps head, the vertebral plate rongeur with the suction device function integrates suction, bone cutting, hemostasis and other actions, the treatment process is simplified, and the operation efficiency is improved, however, the vertebral plate rongeur has a larger volume and is not suitable for operation under the condition of narrow space, such as tooth-like process excision under a nasal cavity endoscope.
