Description

Technical Field

[0001] The present application relates to the field of ventriculoscopic surgery, and in particular, to a ventriculoscopic surgery channel expansion device. Background Art

[0002] In current minimally invasive surgical procedures, in order to obtain a good surgical field of view and operating environment, pneumoperitoneum is commonly used to expand the surgical field of view. However, the tissues in some parts of the human body are relatively tight, and it is difficult to achieve the expansion purpose through simple pneumoperitoneum. Usually, an expansion balloon is used for pre-expansion before performing the corresponding operation.

[0003] The structure of the product can refer to a surgical channel expansion device disclosed in Chinese patent document 201922200443.6, which includes an outer tube, an inner tube is inserted into the hollow tubular structure of the outer tube, one end of the inner tube is connected to an airbag fixing plate, an expansion plate is provided on the end of the outer tube away from the airbag, one side of the expansion plate is rotatably connected to the adjusting nut, the outer wall of the inner tube is provided with a female thread matching the male thread of the adjusting nut, a rotating plate is provided at the port of the outer tube close to the airbag, the rotating plate is rotatably connected to the rotating shaft, the rotating shaft is fixed to the port of the outer tube, and a torsion spring is also provided on the rotating shaft. The surgical channel expansion device can completely retract the airbag into the outer tube, place the tube mouth of the outer tube at the position to be expanded, so that the airbag can be easily placed in place, which is very convenient; the setting of the pressure ball can be manually pressurized, which is flexible and convenient; the setting of the rotating plate and the torsion spring makes the outer tube closed when the surgical channel expansion device is not used to prevent contamination, and the airbag can be fixed and protected when in use, which is convenient to use.

[0004] However, this patent cannot guarantee that the patient's head will not shake during the operation, thereby affecting the doctor's operation. Since it does not have an auxiliary function, its practicality is reduced.
