Description

Technical Field

[0001] This utility model relates to the field of breast and thyroid surgery technology, specifically a pipe connection mechanism suitable for breast and thyroid surgical infusion ports. Background Technology

[0002] In the treatment of the breast and thyroid cartilage, such as intravenous infusion or chemotherapy, to reduce adverse effects on blood vessels, subsequent injections can be performed through the implantation of an infusion port, thereby reducing the damage caused to the patient by the injection.

[0003] The prior art (Chinese patent application number 202410530501.4, published on June 14, 2024) discloses a tubing connection mechanism suitable for breast and thyroid surgical infusion ports, including an infusion port body; an interface disposed on one side of the infusion port body; a catheter disposed at the outer end of the interface and communicating with the interface; and an anti-dislodgement fixing component disposed on the outside of the connection between the interface and the catheter. The present invention fixes the anti-dislodgement sleeve to the connecting tube body by inserting the catheter into the connecting tube body, so that the front end of the catheter reaches between the anti-dislodgement cavity and the annular cone, and then inserting the anti-dislodgement sleeve, so that the return spring falls into the anti-dislodgement cavity. Under the elastic action, the return spring returns to its original position, fixing the limiting hook and the limiting block, thereby fixing the anti-dislodgement sleeve to the connecting tube body. In addition, the first fixing ring abuts against the bottom end of the annular cone, clamping the catheter wall, so that the catheter is fixed and prevented from dislodging.

[0004] Although current infusion ports can fix the pipeline with a limiting structure after connection, the pipeline is still prone to slippage when the clamping force is small. When the limiting clamping force is too large, the pipeline is easily squeezed and deformed, causing the pipeline to be blocked, thus affecting the smooth passage of liquid and hindering the use of the equipment. Utility Model Content

[0005] The purpose of this invention is to provide a pipe connection mechanism suitable for breast and thyroid surgical infusion ports, in order to solve the problems mentioned in the background art. Although the infusion port can fix the pipe through the limiting structure after being connected to the pipe, the pipe is still prone to slippage when the clamping force is small, and the pipe is easily squeezed and deformed when the limiting clamping force is too large, resulting in the pipe being closed.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tubing connection mechanism suitable for breast and thyroid surgical infusion ports, comprising a base, a connector, and a connecting conduit. The connector is fixed to the side of the base, and a connecting conduit is connected to the outer side of the connector. A connector is fixed to the outer end of the connector. The connecting conduit is inserted into the connector and connected to the connector. A support ring is provided inside the connector, and a support mechanism is fixed in the middle of the support ring.

An annular elastic sealing ring is provided on the outer side of the support ring. The elastic sealing ring is fixedly connected to the connector, and a cavity is provided on the outer side of the elastic sealing ring. An increase in air pressure in the cavity pushes the elastic sealing ring to expand and seal and fix the connecting conduit. A sealing control mechanism is provided on the right side of the cavity.

[0007] To further optimize this technical solution, the horizontal center line of the support ring and the horizontal center line of the connector are set to coincide with each other, and the outer diameter of the support ring and the inner diameter of the connecting conduit are equal.

[0011] To further optimize this technical solution, a guide cover is fixed to the right side of the support ring, and the right side of the guide cover has an inclined structure design, and an opening is provided on the surface of the guide cover.

[0012] To further optimize this technical solution, the sealing control mechanism includes a replenishment chamber, a piston, and a pushing mechanism;

[0013] The supplementary cavity is located on the right side of the cavity, and the interior of the supplementary cavity and the interior of the cavity are interconnected.

[0014] The piston is positioned inside the replenishment chamber and between the replenishment chamber to form a horizontal sliding structure;

[0015] The pushing mechanism, located on the right side of the piston, controls the movement of the piston.

[0019] To further optimize this technical solution, the right end of the control rod is fixed with an enlarged end, and the inside of the connecting cover is provided with an annular sliding groove. The enlarged end is located inside the sliding groove and forms a sliding connection with the sliding groove.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] (1) The connection between the connecting conduit and the interface is achieved by inserting the connecting conduit into the connector. The connecting conduit can be pulled out from the connector afterward, making replacement and disassembly convenient. A support ring is provided in the connector to provide inner support for the connecting conduit and prevent it from being squeezed and deformed.

[0022] (2) The inclined guide cover can guide the connecting tube to be inserted into the outside of the support ring, thus supporting the connecting tube and sealing and fixing it with the elastic sealing ring.

[0023] (3) The deformation of the elastic sealing ring can be controlled by the change of air pressure in the cavity, thereby controlling the connection between the elastic sealing ring and the connecting tube, which facilitates the subsequent insertion and removal of the connecting tube, and also improves the installation sealing of the connecting tube.

[0024] (4) The gas in the cavity can be compressed by the movement of the piston, thereby adjusting the gas pressure in the cavity. The movement of the piston can be controlled by the rotation of the connecting cover, making the operation convenient and quick. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1-6 The present invention provides the following technical solution: a pipe connection mechanism suitable for breast and thyroid surgical infusion ports, including a base 1, a docking port 2 and a connecting conduit 4, wherein the docking port 2 is fixed to the side of the base 1 and the connecting conduit 4 is connected to the outside of the docking port 2.

[0034] Example 1: This example provides the following technical solution, which discloses that a connector 3 is fixed to the outer end of the interface 2, and a connecting conduit 4 is inserted into the interior of the connector 3 to connect to the interface 2. A support ring 5 is provided inside the connector 3, and a support mechanism is fixed in the middle of the support ring 5. The support mechanism is connected to the connector 3 and provides inner support for the connecting conduit 4 through the support ring 5. An annular elastic sealing ring 10 is provided on the outer side of the support ring 5. The elastic sealing ring 10 is fixedly connected to the connector 3, and a cavity 11 is provided on the outer side of the elastic sealing ring 10. The increased air pressure in the cavity 11 pushes the elastic sealing ring 10 to expand and seal and fix the connecting conduit 4. A sealing control mechanism is provided on the right side of the cavity 11.

[0035] The connecting conduit 4 can be connected to the interface 2 by inserting it into the connector 3. After the connecting conduit 4 is inserted into the connector 3, the support ring 5 will move to the inside of the connecting conduit 4 to provide support for the connecting conduit 4 and prevent the connecting conduit 4 from being deformed by pressure. Then, by controlling the air pressure of the cavity 11, the elastic sealing ring 10 expands and presses the connecting conduit 4 tightly against the surface of the support ring 5 to achieve sealing and fixing of the connecting conduit 4.

[0036] Example 2: Based on Example 1, the horizontal center line of the support ring 5 and the horizontal center line of the connector 3 are arranged to coincide with each other, and the outer diameter of the support ring 5 and the inner diameter of the connecting conduit 4 are equal. The support mechanism includes a fixing plate 8 and a support frame 9. The fixing plate 8 is fixed to the inner side of the support ring 5, and the support frame 9 is fixed to the left side of the fixing plate 8. The fixing plate 8 and the connector 3 are fixedly connected. A guide cover 6 is fixed to the right side of the support ring 5. The right side of the guide cover 6 is designed with an inclined structure, and an opening 7 is opened on the surface of the guide cover 6.

[0037] When the connecting conduit 4 is inserted into the connector 3, the connecting conduit 4 is first inserted to the outside of the guide cover 6, and moves along the guide cover 6 to the outside of the support ring 5, so that the support ring 5 can move accurately into the inside of the connecting conduit 4.

[0038] Example 3: Based on Example 1, a sealing control mechanism is disclosed, including a replenishing cavity 12, a piston 13, and a pushing mechanism. The replenishing cavity 12 is located on the right side of the cavity 11, and the interior of the replenishing cavity 12 and the interior of the cavity 11 are interconnected. The piston 13 is located inside the replenishing cavity 12 and forms a horizontal sliding structure between the replenishing cavity 12 and the cavity 11. The pushing mechanism is located on the right side of the piston 13 to control the movement of the piston 13. The pushing mechanism includes a control rod 14 and a connecting cover 15. The control rod 14 is fixed on the right side of the piston 13. The connecting cover 15 is located on the right side of the control rod 14, and a sliding connection is formed between the control rod 14 and the connecting cover 15. The connecting cover 15 is located on the outside of the connecting member 3 and forms a threaded connection between the connecting member 3 and the connecting member 3. An enlarged end 1401 is fixed at the right end of the control rod 14. An annular groove 16 is opened inside the connecting cover 15. The enlarged end 1401 is located inside the groove 16 and forms a sliding connection between the groove 16 and the connecting member 16.

[0039] After the connecting conduit 4 is inserted into the outside of the support ring 5, the connecting cover 15 can be rotated. The connecting cover 15 moves through the threaded connection with the connecting piece 3, which drives the control rod 14 to move. The control rod 14 drives the piston 13 to move, causing the piston 13 to squeeze the filling chamber 12. The air pressure in the cavity 11 increases, and the volume of the elastic sealing ring 10 expands, sealing and fixing the connecting conduit 4. When the connecting conduit 4 needs to be removed later, the connecting cover 15 can be rotated in the opposite direction.

[0040] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0041] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
