[0001] This utility model relates to the field of sealing silicone parts technology, and in particular to a sealing silicone part used in cannula puncture devices. Background Technology

[0002] A trocar is a medical consumable. Trocars can be used in various minimally invasive surgical procedures. They are used by specialists to puncture the abdominal cavity during laparoscopic surgery, deliver gas into the abdominal cavity, and establish a passage for endoscopes and surgical instruments to enter and exit the abdominal cavity from the outside. They are common medical devices in the medical field.

[0003] Traditional trocar insertion devices require the use of sealing silicone components to seal and fix the internal components. These sealing silicone components are generally of a fixed volume and size. However, when used with the device, which needs to rotate frequently, gaps will appear between the devices. Traditional sealing silicone components cannot compensate for these gaps, resulting in gaps in the device during operation. This affects the normal function of the device and may even cause secondary injuries to the user, which is extremely dangerous. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0022] like Figures 1 to 3 As shown, a sealing silicone component for use with a cannula includes an outer sealing gasket 1. Annular sealing sheets 3 are fixedly connected to the top and bottom of the inner side of the outer sealing gasket 1. Both annular sealing sheets 3 have annular corrugated structures. A surgical instrument sealing ring 4 is fixedly connected to the center of both annular sealing sheets 3. The surgical instrument sealing ring 4 has an annular hollow airbag structure. Several elastic tie posts 6 are fixedly connected to the outer side of the outer wall of the surgical instrument sealing ring 4. The ends of the elastic tie posts 6 away from the surgical instrument sealing ring 4 are fixedly connected to the inner side of the outer sealing gasket 1.

[0023] As an optional technical solution of this utility model, the feature is that: a sealing groove 2 is provided on the top surface and the middle of the top surface of the outer sealing gasket 1. The cross-section of the sealing groove 2 is a U-shaped structure with a larger top and a smaller bottom. The sealing groove 2 with a U-shaped structure allows the pressing structure of the cannula puncture device installation part to be pressed in, thereby improving the sealing effect of the connection.

[0024] As an optional technical solution of this utility model, the inner side of the surgical instrument sealing ring 4 is provided with an arc protrusion 5 protruding towards the center. The outer sealing gasket 1, the annular sealing sheet 3 and the surgical instrument sealing ring 4 are all made of medical silicone. Through the arc protrusion 5 of the surgical instrument sealing ring 4, it can be compressed according to the diameter of the surgical instrument, thereby adapting to the sealing of surgical instruments of different diameters. At the same time, it can hold the outer wall of the surgical instrument tightly. Through the friction of the holding, it can provide a certain support force for the surgical instrument.

[0025] As an optional technical solution of this utility model, a plurality of elastic tie posts 6 are arranged in a radial annular array around the center of the surgical instrument sealing ring 4. The vertical distribution range of the plurality of elastic tie posts 6 is adapted to the thickness of the outer sealing gasket 1 and the surgical instrument sealing ring 4, so that the elastic tie posts 6 provide uniform tension in all directions, so that the force is uniform when moving and flipping the surgical instrument, and the surgical instrument is easy to control.

[0026] As an optional technical solution of this utility model, the distance between the outer side of the surgical instrument sealing ring 4 and the inner side of the outer sealing gasket 1 is less than the extension range of the annular sealing sheet 3 and the elastic tie column 6, so that the extension and contraction of the annular sealing sheet 3 and the elastic tie column 6 can meet the need for the surgical instrument sealing ring 4 to move flexibly within the range of the inner side of the outer sealing gasket 1.

[0027] The sealing silicone component used with this cannula puncture device requires the following steps during use:

[0028] 1) First, install the outer sealing gasket 1 at the top of the cannula puncture device. The structure of the cannula puncture device compresses the outer sealing gasket 1 to achieve position fixation and structural sealing.

[0029] 2) Then the surgical instrument is inserted through the center of the inner side of the surgical instrument sealing ring 4 into the inner wall of the cannula trocar, and then into the patient's body;

[0030] 3) The surgical instrument sealing ring 4 tightly hugs the outer wall of the surgical instrument, forming a seal with the outer wall of the surgical instrument. At the same time, the surgical instrument sealing ring 4 and the outer sealing gasket 1 are connected by the elastic tie post 6 and the annular sealing piece 3, so that the surgical instrument sealing ring 4 can move, rotate and flip flexibly within the range of the inner wall of the outer sealing gasket 1, so as to facilitate the operation of the surgery.

[0031] 4) The arc-shaped protrusion 5 of the surgical instrument sealing ring 4 can be compressed according to the diameter of the surgical instrument, thereby adapting to the sealing of surgical instruments of different diameters. At the same time, it can hold the outer wall of the surgical instrument tightly. Through the friction of the tight grip, it can provide a certain support force for the surgical instrument, so that the surgical instrument has a certain positioning fulcrum during the operation, which is convenient for the doctor to operate and makes the operation more effortless. Moreover, the elastic tie column 6 pulls, so that there is a certain damping force when moving and flipping, which facilitates the control of the force during the operation.

[0032] In summary, the surgical instrument sealing ring 4 tightly grips the outer wall of the surgical instrument, forming a seal. Simultaneously, the surgical instrument sealing ring 4 is connected to the outer sealing gasket 1 via an elastic tie post 6 and an annular sealing sheet 3. This allows the surgical instrument sealing ring 4 to move, rotate, and flip flexibly within the inner wall of the outer sealing gasket 1, facilitating surgical operations. It also effectively seals gaps. The arc-shaped protrusion 5 of the surgical instrument sealing ring 4 can be compressed according to the diameter of the surgical instrument, adapting to sealing different diameter surgical instruments. Furthermore, the tight grip on the outer wall of the surgical instrument provides support through friction, giving the surgical instrument a fulcrum for positioning during surgery, facilitating the surgeon's operation and reducing effort. The elastic tie post 6 also provides damping force during movement and flipping, facilitating force control during operation.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
