When the rotating portion is rotated to the pressing block 312 to press the handle insertion portion to be non-rotatable, the fixing sleeve is considered to be completely fixed with the handle insertion portion.

In other preferred embodiments, as shown in fig. 5 and 6, the rotary self-locking type fixing sleeve 320 includes a second fixing sleeve body 323 and a locking ring 322 disposed on an outer ring of the second fixing sleeve; the connecting part between the second fixing sleeve body 323 and the endoscope handle part is a plurality of fastening pieces 321 cut along the length direction of the second fixing sleeve body 323, gaps are reserved between adjacent fastening pieces 321, threads are arranged on the outer ring of each fastening piece 321, the locking ring 322 is rotated to enable the fastening pieces 321 to be close to each other or far away from each other, the inner diameter of the connecting part is reduced or enlarged, and the fixing and loosening of the fixing sleeve 300 and the endoscope handle part inserted into the fixing sleeve 300 are realized.

By providing a plurality of fastening tabs 321 cut along the length of the second fixing sleeve body 323, a gap is provided between adjacent fastening tabs 321, and by tightening or expanding the gap, the diameter of the orifice of the fixing sleeve 300 can be reduced or increased. When the handle insertion portion is inserted into the second fixing sleeve 323, fixing the handle insertion portion into the second fixing sleeve 323 and releasing the fixing are achieved by tightening or expanding the gap of the adjacent fastening pieces 321.

The preferred fastening and loosening means is by means of a locking ring 322 provided on the outer circumference of the second fastening sleeve body 323, said locking ring 322 being provided at the location of the fastening tab 321. The outer wall of the fastening piece 321 is provided with a thread, and correspondingly, the inner wall of the locking ring 322 is provided with a corresponding thread, and the gap between the fixing pieces can be tightened by rotating the locking ring 322 towards the handle portion of the endoscope, so that the second fixing sleeve 323 and the handle insertion portion can be fixed. Likewise, rotating the locking ring 322 in the opposite direction to the handle portion of the endoscope may enlarge the gap between the fixing plates to loosen the second fixing sleeve 323 for fixation, so that the handle insertion portion is removed.

Preferably, the fixing sleeve 300 is made of hard plastic, and in other preferred embodiments, the inner layer of the fixing sleeve 300 is made of soft silica gel, so as to increase the anti-skid property.

Preferably, the compression block 312 is made of soft plastic to prevent the handle from being crushed.

As shown in fig. 7 and 8, in a preferred embodiment, a detachable tubular lock 400 is further disposed at the connection end of the sleeve body 100 and the puncture outfit 200, and the inner diameter of the lock 400 is smaller than the inner diameter of the sleeve; the sleeve provided with the lock head 400 is inserted into the puncture outfit 200 to complete the connection.

The locking head 400 is detachably disposed on the port of the sleeve body 100, preferably by using a threaded connection. The top of the locking head 400 is approximately conical, i.e., the diameter of the top is slightly smaller than the diameter of the bottom, to facilitate insertion of the locking head 400 into the sheath 200.

The lock head 400 is used for restraining an insertion portion of the endoscope and preventing the endoscope from shaking in the sleeve. Thus, the sleeve of the present invention can be adapted to a multi-sized endoscope insertion portion by changing the size of the locking head 400. The tapered end with the proper opening size is selected according to the diameter of the endoscope insertion tube.

In a preferred embodiment, the lock head is made of transparent PC, PETG or transparent or semitransparent plastic with higher hardness. And according to the size of the insertion tube, interchangeable locking heads with different diameters (different colors can be used).

Also included in the preferred thoracoscopic sleeve is a segmented thoracoscopic sleeve, the rigid sleeve body 100 having a soft sleeve body 500 attached to the end remote from the penetrator.

That is, the thoracoscopic cannula of the present invention has a rigid transparent plastic tube 100 at the anterior section (proximal to the penetrator) and a flexible transparent plastic tube 500 at the posterior section (proximal to the stationary sleeve), which is more convenient for the physician to bend the endoscope insertion tube during operation than a rigid cannula as a whole. The whole body is hard and difficult to bend, and the operation is inconvenient.

For the above technical solution, the two ends of the hard cannula main body 100 are the puncture outfit 200 and the connecting ring 600, the two ends of the soft cannula main body 500 are the connecting ring 600 and the fixing sleeve 300, and the technical solution of using the thoracoscopic cannula of the hard cannula main body can be directly applied to the segmented thoracoscopic cannula.

In the thoracoscopic cannula using the hard cannula body, although fatigue of searching for a position and adjusting a position during operation using a soft endoscope insertion tube for a long time is improved, the hard cannula body allows a user to perform the same operation for a long time.

Therefore, the invention also provides another preferable technical scheme, namely, the thoracoscope sleeve is divided into a hard section and a soft section, the hard section is used for fixing the direction of the endoscope insertion part, the soft section is used for adjusting the position of the connected handle, so that a user can adjust the handle to be comfortable, or the position of the handle can be changed according to the use habit.

The soft section of the sleeve of the invention can enable a user to move the endoscope according to the requirement, thereby preventing fatigue caused by the same action for a long time. The hard segment plays a role in stabilizing, and is easier to point to a precise position along with the movement of a user.

In a preferred chest embodiment, the rigid sleeve body is combined with the soft sleeve body by a connecting ring to form a sleeve body.
