Problems solved by technology

The traditional spinal mirror working sheath does not have the function of high-pressure perfusion. The high-pressure state generated by the perfusion pressure during the high-pressure perfusion of the spinal mirror will aggravate the pain of the patient. Continuous high pressure may cause nerve damage. In severe cases, it may cause dura mater rupture and stop the operation. Surgical risks brought about by continuous high pressure generally need to increase the sealing cap or replace the hand instrument to achieve the conversion between high pressure and low pressure. The operation is cumbersome and increases the difficulty of the operation.
The existing patent document CN201910726720.9 discloses a high-pressure perfusion surgical endoscope with a special-shaped outer working tube, which discloses the function of high-pressure filling, but does not have a structure that can realize high-low pressure rapid conversion to avoid continuous high pressure risks of surgery
Moreover, the disclosed working pipe sleeve structure and the corresponding water outlet channel structure are designed based on the outer working pipe with a ring-shaped (special-shaped) pipe cross-section, and are not suitable for the outer working pipe with an ordinary circular pipe cross-section.

Abstract

The invention discloses a spinal endoscope safety working sheath capable of quickly switching perfusion pressure, which comprises a sheath tube and a switching control assembly, and one end of the sheath tube is embedded into the switching control assembly; the sheath tube comprises a water channel and a working tube channel I; the working tube channel I is used for containing an endoscope outer working tube, the switching control assembly comprises a conduction column body, a sheath tube embedding groove is formed in one end of the conduction column body, a sheath tube is embedded into the sheath tube embedding groove, a drainage hole is formed in the middle of the conduction column body, and a switching structure used for controlling sealing or conduction of the drainage hole is arranged on the conduction column body. A working pipe channel II communicated with the working pipe channel I penetrates through the conduction column body, and a handle is arranged on the outer side of the end portion of the other end of the conduction column body. A switching structure is arranged on the working sheath handle, a doctor can freely select and rapidly switch the opening / closing state of a working sheath water channel according to clinical adaptation disease requirements in an operation, namely the high-pressure / low-pressure state generated by perfusion pressure in the operation, surgical instruments do not need to be additionally added or replaced, and the surgical operation difficulty is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a spinal endoscope safety working sheath capable of rapidly converting perfusion pressure. Background technique [0002] In clinical operations, it is usually necessary to use a working sheath to provide an instrument channel for medical instruments, and the working sheath is an indispensable auxiliary instrument in endoscopic surgery. The traditional spinal endoscopic working sheath does not have the function of high pressure perfusion. The high pressure state generated by the perfusion pressure during the high pressure perfusion of the spinal endoscope will aggravate the pain of the patient. Continued high pressure has the risk of nerve damage. In severe cases, the dura may rupture and the operation will be terminated. The surgical risk brought by continuous high pressure generally requires adding a sealing cap or replacing hand instruments to realize the conversion bet...
