Detailed description of the invention
The first embodiment of the present invention as shown in Figure 1-2 discloses a kind of threaded sleeve, consistent with prior art, and it comprises: housing 1 and be arranged in described housing 1, the inner chamber that plays Minimally Invasive Surgery operating theater instruments channeling.In order to increase the frictional force of sleeve pipe and tissue to ensure that sleeve pipe can not come off in operation process, the present embodiment is provided with 2 groups of symmetrical ratchet groups protruding from described outer surface on the outer surface of described housing 1, often organize ratchet group to be made up of the ratchet 2 that at least 2 are arranged along described housing 1 axis direction, described ratchet is all intermittently distributed in the outer surface of described housing, is discontinuity zone 3 between 2 ratchets 2 on described adjacent same circumferential cross section.Described discontinuity zone 3 is the outer surface of described housing 1.
In this example, the corresponding ratchet 2 of described 2 groups of ratchet groups is positioned on the same circumferential cross section of described housing 1, the axis co-axial of 2 namely corresponding ratchets 2.Described ratchet 2 comprises advance face 4 and retrogressing face 5, so advance face 4 and housing outer surface are that acute angle is arranged, described retrogressing face 5 and housing outer surface at right angles or obtuse angle arrange, both can having ensured that sleeve pipe inserted tissue smoothly when performing the operation, this sleeve pipe also can be made can not to skid off outside tissue in operation process.
In this example, because 2 groups of ratchet groups are symmetrical, therefore relatively between discontinuity zone 3 be approximately a rectangle.The second embodiment shown in Fig. 3-4, the difference of itself and the first embodiment is: the same circumferential cross section of described housing 1 is provided with at least 2 ratchets 2, and the interlaced arrangement of ratchet 2 on adjacent cross section, be similar to " wall brick " arrangement.And same, the outer surface of the described housing 1 between 2 ratchets 2 is discontinuity zone 3.
