Firstly, a stainless steel wire connecting rope 8 is embedded on a stainless steel inner pipe 3, then the stainless steel inner pipe 3 embedded with stainless steel wires is inserted into a stainless steel outer pipe 2 (note that a through groove 10 (long groove) on the pipe wall of the inner pipe 3 and a through hole 9 (round hole) on the pipe wall of the outer pipe 2 are in one direction), and the inserted metal wires extend out from a threaded bent pipe groove at the tail end of the stainless steel outer pipe 2 and are firmly melted with a pipe cap 21 at the tail end of the pipe;

sleeving the outer sleeve 1 into the stainless steel outer pipe 2 to be aligned with the pipe cap 21, wherein the pipe cap 21 slightly extends out of the outer sleeve 1 a bit;

the flow control piece 4 is sleeved on the stainless steel outer pipe 2 (note that the small round hole on the side surface of the flow control piece 4 and the small round hole on the side surface of the outer pipe 2 are on one surface) and fixed firmly;

pressing the universal driving shaft 5 into the spline nut 6;

screwing the end fixing piece 7 into the spline nut 6 clockwise;

the assembled universal driving shaft 5, the spline nut 6 and the tail end fixing piece 7 are sleeved into the stainless steel outer tube 2 together, and the fixing is firm (the sleeving direction refers to the figure);

the side small hole is aligned to the side small hole of the outer tube 2 by rotating the linkage shaft 5, and the I-shaped screw is screwed in.

The inner tube 3 is connected with the outer tube 2 through a connecting rope 8, wherein the inner tube 3 is a power rod, a tube cap 21 and a threaded tube groove 22 of the outer tube 2 are driven rods, a power source is from a linkage shaft 5, a spline nut 6 and a terminal fixing part 7 assembly, the linkage shaft 5 can be linked and retreated simultaneously when the spline nut 6 is rotated backwards, the linkage shaft 5, the spline nut 6 and the inner tube 3 are connected together through a straight screw, the linkage shaft 5 and the spline nut 6 drive the inner tube 3 to move backwards while moving backwards, a multi-section cutting groove is arranged at the tail end and on the side face of a connecting point of the outer tube 2, and the tail end can be slowly bent towards the inside of the multi-section cutting groove in the backward pulling force process. Twisting the internal structure of the spline nut 6 forward releases the previous pulling force and the threaded tube groove 22 returns to its restoring force to return the end of the outer tube 2 to a straight state.

The anti-falling clamping groove 11 at the tail end of the tail end fixing piece 7 plays a role in connecting a flushing and sucking pipeline in the using process;

the main function of the outer sleeve 1 is to block water flow from leaking from the side pipe holes of the outer pipe 2 when in use;

the function of the 2.8 mm round hole on the side of the flow control element 4 is that when in use, the flow of inlet and outlet water is controlled by the pressing degree of fingers of an operator.

The use principle is as follows: firstly, the flushing and sucking hose is butted with the tail end fixing part 7, the top end of the brain flusher is checked to be in a straight state, the brain flusher in the straight state stretches into the position of an affected part needing to be cleaned to be flushed, and the circular hole on the side surface of the flow control part 4 is pressed by fingers to adjust the water flow in the hose. If the affected part of the side cavity which needs to be cleaned appears, the spline nut 6 is manually adjusted to adjust the flushing and sucking angle of the top end of the flushing and sucking device, so that the affected part can reach the optimal cleaning state. After the cleaning is finished, the spline nut 6 is turned backwards by hand to enable the tail end of the flushing and sucking device to be restored to a straight state, and the flushing and sucking device can be drawn out from the affected part.

The craniocerebral operation instrument has the advantages that the craniocerebral operation instrument has a relatively complex structure in the craniocerebral operation, usually, the lateral cavity affected points are difficult to clean, and the conventional flushing instrument enters a narrow cavity and then can flush the affected point positions in the right front direction, but because some affected points can appear on the side face, the conventional flushing instrument cannot effectively clean the affected points because the conventional flushing instrument cannot be bent, and the optimal design scheme can realize the all-dimensional cleaning of the affected points by artificially adjusting the bent angle of the tail end of the flushing and sucking device.

All the technical features of the above embodiments can be arbitrarily combined (as long as there is no contradiction between the combinations of the technical features), and for brevity of description, all the possible combinations of the technical features in the above embodiments are not described; these examples, which are not explicitly described, should be considered to be within the scope of the present description.

The present invention has been described in considerable detail with reference to certain embodiments and examples thereof. It should be noted that, without departing from the inventive concept, it is obvious that several variations and modifications can be made to the specific embodiments, which fall within the scope of protection of the present application. Therefore, the protection scope of the present patent application shall be subject to the appended claims.
