Detailed Description

The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.

Example (b): a laparoscope puncture outfit with a noise reduction structure;

referring to fig. 1, including a puncture (at a in fig. 2) and a sheath 2;

a sleeve 1 is fixedly arranged on the sheath tube 2, and a first sealing ring 3 and a second sealing ring 6 are arranged in the sleeve 1;

both sides of the bottom of the first sealing ring 3 are provided with inclined parts, and the inclined parts on both sides are intersected at the bottom of the sealing ring 3, as shown in fig. 1, the inclined parts are favorable for increasing the radial holding force of the sealing ring, and when a surgical instrument penetrating through the sealing ring rotates, the surgical instrument can be tightly held by the sealing ring, so that the sealing effect is achieved.

Referring to fig. 1, the top of each of the first seal ring 3 and the second seal ring 6 is provided with a downward-turned outer edge. The outer edge of the first sealing ring 3 is sleeved on the upper edge of the sleeve 1.

Referring to fig. 1-3, a positioning member 4 is pressed above the first sealing ring 3, and the positioning member 4 is fixed on a bolt post 11 extending from the inner wall of the casing 1 by using a bolt when being installed.

A positioning ring 5 is sleeved on the positioning piece 4; referring to fig. 1, a stopper 5 is fixedly installed on the inner side wall of the positioning ring 5, and a concave-shaped limiting groove is formed on the stopper 5;

the outer side wall of the positioning piece 4 is also provided with a limiting part 41; when the positioning ring 5 is sleeved on the positioning piece 4, the bottom surface of the positioning ring 5 is contacted with the upper end surface of the positioning piece 4; in addition, the bottom surface and the side surface of the stopper portion 41 are attached to the inner groove surface 5 of the stopper groove, thereby performing a stopper function.

In addition, both sides of the stopper 5 are of a spring-leaf structure, as can be seen in fig. 4.

The outer edge of the second sealing ring 6 is sleeved on the upper edge of the positioning member 4, as shown in fig. 2 and 3. The upper edge of the second seal ring 6 is provided with an extension end (at B in fig. 3).

The cover sleeve 7 is covered above the second sealing ring 6, an inner groove is arranged on the inner bottom surface of the cover sleeve 7, when the cover sleeve is installed, the extending end is contained in the inner groove, and the cover sleeve and the inner groove are tightly connected.

In addition, a gap 71 is arranged on the outer side wall of the cover sleeve 7; when mounted, the extension of the positioning ring 5 is received in the gap 71.

When the sheath pipe sealing device works, firstly, two layers of sealing rings are arranged from the aspect of sealing performance, the sealing rings are arranged on the structure of the sheath pipe 2 in a sleeved mode, and when the sheath pipe sealing device works from the aspect of figure 2, the sealing rings are not in contact with the inner wall of the sheath pipe 2, and the influence of the external structure on the sealing rings is small. The two layers of sealing rings can independently generate sealing function, so the sealing effect is more stable and durable.

From the viewpoint of structural stability, first, the first seal ring 3 is pressed and fixed by the positioning member 4; the first sealing ring 3 is certainly closely attached to the upper positioning piece 4 of the first sealing ring and is also buckled with the lower sleeve 1 of the first sealing ring, in addition, the sleeve 1 is fixedly connected with the positioning piece 4 through bolts, and the surgical equipment tightly held by the first sealing ring 3 cannot be impacted to make a sound even when moving back and forth;

furthermore, three mutually buckled structures, namely a positioning ring 5, a cover sleeve 7 and a positioning piece 4, are arranged in the installation of the second sealing ring 6; from top to bottom, the cover sleeve 7 is buckled above the second sealing ring 6 and is tightly connected with the second sealing ring 6 under the action of the pre-tightening force of the extension end of the second sealing ring; on the basis, the cover sleeve 7 is buckled with the positioning ring 5, and the combination of the arranged gap and the extending part can prevent the cover sleeve 7 from rotating in use, so that the second sealing ring 6 generates torsion; on the basis of sleeving between the positioning ring 5 and the positioning piece 4, a limiting structure (namely a limiting groove and a limiting part 41) is additionally arranged; it is worth mentioning here that the deformable structure arranged in the limiting groove can effectively prevent the limiting groove from being worn to generate a gap in use, and then the collision sound is generated in use.

The mounting structure of the second sealing ring is compact, and the first sealing ring shares a part of acting force in use, so that the structure of the second sealing ring is more stable, the sealing effect is better, and impact sound cannot be generated.
