[0041] In order to facilitate understanding of the purpose, technical solutions and effects of the present invention, the present invention will now be further described in detail in conjunction with embodiments.

[0042] like Figure 1 and Figure 2 As shown, an anti-drop-off sleeve assembly of a shoulder arthroscopy of the present invention comprises: a sheath tube component 10, which has a cavity 11 for accommodating a scope sheath component 30 and an anti-drop-off component 20; the anti-drop-off component 20, which is arranged in the cavity 11 and the barbs 24 thereon are pressed against the inner wall of the sheath tube component 10; the scope sheath component 30, which comprises a handle 31 and a sheath body 32, and the sheath body 32 is inserted into the hollow cavity of the anti-drop-off component 20 for penetrating into a preset position of the shoulder joint.

[0043] The anti-drop-off sleeve assembly of a shoulder arthroscopy of the present invention, when in use:

[0044] When performing minimally invasive shoulder surgery, the medical staff first uses the scope sheath to perforate the surgical site on the shoulder joint, then pulls out the scope sheath and screws the sheath tube 13 into the perforation for preliminary fixation; then the medical staff holds the handle 26 of the anti-dropping piece 20 and lifts the anti-dropping piece 20 upward with force, that is, the barbs 24 on the anti-dropping piece 20 will pierce the easy-to-perforate hole 12 on the sheath tube 13 and enter the side wall of the perforation at the surgical site of the human body, thereby achieving the purpose of further fixation; then, a negative pressure device is connected to the negative pressure interface 14 on the sheath tube 13 to drain and discharge waste debris, impurities and blood so that the shoulder arthroscopy can penetrate into the joint cavity through the sheath tube 13 to observe the pathological conditions in the joint cavity;

[0045] The present invention provides an anti-drop-off sleeve assembly for shoulder arthroscopy, in which the anti-drop-off component 20 is designed on the basis of the original existing design. After the anti-drop-off component 20 is inserted into the surgical puncture, the medical staff can operate it by pulling it upward with force to achieve the purpose of fixing the barbs 24. When the sheath 13 needs to be removed after the operation, the medical staff can press the anti-drop-off component 20 downward with force to retract the barbs 24 into the inner wall of the sheath 13, which will not affect the normal removal of the sheath 13.

[0046] It should be noted that the anti-drop-off sleeve assembly of the shoulder arthroscopy of the present invention has a length of 55-90 mm and a diameter range of 5.5-8.5 mm; it should be noted that the anti-drop-off parts 20 of different types of sheath tubes 13 are of different models, and the principle is that they can be used in conjunction with each other; in order to ensure the normal work of the barb 24, the length range of the barb 24 can be 2-4 mm.

[0047] like Figure 1 As shown, an anti-drop-off sleeve assembly for shoulder arthroscopy of the present invention, the anti-drop-off component 20 includes a hollow ring sleeve 21 clamped on the top end of the sheath tube component 10, and a plurality of barbs 22 arranged below the hollow ring sleeve 21; the barbs 22 are at least two groups, which include a vertical rod 23 and a plurality of barbs 24 arranged on the vertical rod 23; the pointed end 25 at the top end of the barb 24 is arranged corresponding to the easy-to-pierce hole 12 correspondingly arranged on the sheath tube component 10.

[0048] The present invention provides an anti-drop-out sleeve assembly for a shoulder arthroscopy, wherein the anti-drop-out component 20, wherein the hollow ring sleeve 21 and the barbed component 22 are both placed in the cavity 11 of the sheath tube 13; at the same time, it should be noted that the hollow ring sleeve 21 is connected to the head end 16 of the sheath tube 13 by means of a snap connection.

[0049] The barbs are multiple groups. When there are two groups, they are respectively arranged on the left wall and the right wall corresponding to the sheath tube 13, and the spike ends 25 of the barbs are arranged corresponding to the easy-to-pierce holes 12 correspondingly arranged on the sheath tube 10. It should be particularly noted that when the barbs 24 are not lifted upward with a large force, they are still a distance away from the easy-to-pierce holes 12 on the sheath tube 13, and when they are lifted, a large force must be used to achieve the purpose of puncturing the easy-to-pierce holes 12;

[0050] like Figure 1 As shown, in an anti-drop-off sleeve assembly for shoulder arthroscopy of the present invention, the number of barbs 24 on each vertical rod 23 is 3-5, and the barbs 24 on each vertical rod 23 are evenly distributed; the angle between the pointed end 25 of the barb 24 and the surface of the vertical rod 23 where it is located is 20-30°.

[0051] In the anti-drop-off sleeve assembly of a shoulder arthroscopy of the present invention, each vertical rod 23 is provided with 3-5 barbs 24, and the positions and quantities of the barbs 24 are arranged corresponding to the easy-to-penetrate holes 12 on the sheath 13, so as to ensure that the two can be used in conjunction with each other.

[0052] like Figure 3 and Figure 4 As shown, an anti-falling sleeve assembly for a shoulder arthroscopy of the present invention, the left and right side walls of the top of the hollow ring sleeve 21 are provided with a straight handle 26; the handle 26 is vertically connected to the hollow ring sleeve 21; the hollow ring sleeve 21 is embedded in the head end of the top of the sheath tube 10, and the two are connected by a snap-fitting manner; a plurality of grooves 27 are provided on the side wall of the hollow ring sleeve 21, and a convex strip 17 corresponding to the groove 27 is provided on the inner wall of the head end 16.

[0053] It should be noted that a plurality of ridges 17 are provided on the inner wall of the head end 16 of the sheath tube 10, which can be arranged corresponding to the grooves 27 on the side wall of the hollow ring sleeve 21; and it should be noted that the height of the head end 16 is about 5 mm, and the height of the hollow ring sleeve 21 is slightly higher than the head end 16, so that the handle 26 is arranged on the outer side of the top end of the head end, which is convenient for hand-held control.

[0054] like Figure 1 , Figure 3 and Figure 4 As shown, in the anti-drop-off sleeve assembly of a shoulder arthroscopy of the present invention, the easy-to-pierce hole 12 is a thin sheet; the thin sheet and the sheath tube 10 are both made of medical plastics; the diameter of the easy-to-pierce hole 12 is 1 mm.

[0055] The present invention provides an anti-drop-out sleeve assembly for a shoulder arthroscopy. In order to ensure that the anti-drop-out component 20 does not pass through the sheath 13 without reason during transportation or operation, the ring body is embedded in the top end of the sheath component 10, and the two are connected by a snap-fitting manner to ensure that the anti-drop-out component 20 does not fall out easily.

[0056] At the same time, the texture of the thin sheet here is relatively thin, and compared with the wall of the sheath tube 13 next to it, its wall thickness is relatively thin, so it is easy for the barb 24 to pass through.

[0057] like Figure 1 As shown, a shoulder arthroscopy anti-falling sleeve assembly of the present invention, the sheath tube 10 includes a hollow sheath tube 13 and a negative pressure interface 14 arranged near the top of the sheath tube 13 and an annular head end 16 arranged at the top of the sheath tube, the negative pressure interface 14 is used to connect a negative pressure suction device; the outer wall of the sheath tube 13 is provided with an external thread 15.

[0058] like Figure 2 As shown, an anti-drop-off sleeve assembly of a shoulder arthroscopy of the present invention, the scope sheath 30 includes a handle 31 and a sheath body 32, the handle 31 is a rounded rectangular shape, and an anti-slip stripe 33 is provided on its outer wall; the top end of the sheath body 32 is integrally connected to the handle 31, and the bottom end thereof is a spike portion 34.

[0059] The structures of the sheath tube component 10 and the scope sheath component 30 are similar to the structure of the current sheath tube 13 component, so they are not described in detail.

[0060] The present invention is further described above in conjunction with the embodiments, but the present invention is not limited to the above-mentioned implementation modes, and various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
