end of the operating wire 10 extends out of the channel and is positioned on the rear sleeve 9.22, In this embodiment, as shown in fig. 3, the connection point of the operation wire 10 and the rear sleeve 9.22 is said to be located at a different position on the circumference of the cylinder than the distal outlet of the passage, and in colloquial terms, the operation wire 10 is said to extend obliquely to the connection point of the rear sleeve 9.22 after extending from the distal outlet of the passage, and this is arranged so that when the operation wire 10 is pulled, it gives not only an axial component force to the rear sleeve 9.22 to pull the deflection post 9 for deflection, but also a radial component force to the rear sleeve 9.22 to pull it to rotate relative to the inner cylinder 9.1, so that when the operation wire 10 pulls the rear sleeve 9.22, the rear sleeve 9.22 rotates, Meanwhile, because the axial guiding structure, such as the sliding guiding structure of the protrusions and the grooves arranged on the inner wall of the front sleeve 9.21 and the outer wall of the inner column 9.1, is arranged between the front sleeve 9.21 and the inner column 9.1, the sliding axial guiding structure is not described in detail in the prior art, the axial guiding structure is used for guiding the front sleeve 9.21 to move in the axial direction, the rear sleeve 9.22 and the front sleeve 9.21 are all wavy cylinders, the rear sleeve 9.22 rotates to drive the front sleeve 9.21 to reciprocate in the axial direction instead of synchronously rotating, in the reciprocating movement stroke of the front sleeve 9.21, the front sleeve 9.21 has a butt joint position and a jacking position, In the abutting position, the wave crest of the front sleeve 9.21 abuts against the wave crest of the rear sleeve 9.22, the wave trough of the front sleeve 9.21 abuts against the wave trough of the rear sleeve 9.22, the abutting surfaces of the wave crest and the wave trough of the front sleeve 9.21 abut against each other as shown in fig. 3, in the jacking position, the wave trough of the front sleeve 9.21 abuts against the wave crest of the rear sleeve 9.22, the wave crest of the front sleeve 9.21 and the wave trough of the rear sleeve 9.22 are in opposite positions, only the abutting positions contact with each other, and the rest has a larger space, namely as shown in fig. 4, when the front sleeve 9.21 is in the jacking position from the abutting position, The front sleeve 9.21 is moved forward distally relative to the rear sleeve 9.22, so that the front sleeve 9.21 achieves a light collecting effect on the first lighting device 4.3, i.e. a concentrated light source on the first lighting device 4.3, an elastic return structure such as a second torsion spring is arranged between the rear sleeve 9.22 and the inner cylinder 9.1, the second torsion spring is used for returning the outer sleeve 9.2 from the jacking position to the abutting position, an elastic member can be arranged correspondingly for returning the front sleeve 9.21, when the rear sleeve 9.22 rotates to a position where the operation wire 10 is axially consistent with the channel, the rear sleeve 9.22 stops rotating and the front sleeve 9.21 is at the jacking position, the operation wire 10 is then pulled further, since the rear sleeve 9.22 cannot continue to rotate, the deflection column 9 is forced to deflect, obviously, in order to deflect the deflection column 9 after the rear sleeve 9.22 rotates, the elastic force of the second torsion spring is configured to be smaller than that of the first torsion spring, and simultaneously, since the elastic force of the first torsion spring is larger than that of the second torsion spring, the rear sleeve 9.22 firstly generates deflection reset when elastically resetting and then generates rotation reset, the purpose of setting the deflection column 9 is that the range is wider when the naked eye can observe obvious bright spots on the outer side, the front sleeve 9.21 moves forward to concentrate the light source of the first lighting device 4.3 while the deflection column 9 deflects, The position of the first lighting device 4.3 can be more accurately and intuitively understood.
It will be appreciated by those skilled in the art that the above-described configurations on the first light emitting device 4.3 may all be identically configured to the second light emitting device, differing only in the access passage at the time of surgery, the remainder being identical.
