[0002] Currently, puncture suture devices are medical devices mainly used to quickly and accurately close puncture sites during surgery, reducing bleeding, lowering the risk of infection, and promoting patient recovery. Chinese patent CN219147798U specifically discloses an inflatable puncture suture device with an anti-leakage structure. This patent achieves stable sealing and airtightness of the puncture site through an integrated inflatable airbag and a medical-grade silicone cannula, effectively preventing the suture device from falling off and air leakage during surgery. However, the integrated inflatable airbags are all fixed together, making it difficult to clean the multiple integrated components during postoperative cleaning, resulting in poor practicality.

[0003] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0004] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a puncture and suturing device with a balloon, which achieves the effects of convenient cleaning and disinfection and good sealing.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a puncture and suturing device with a balloon, comprising a rod, a balloon and a connecting tube, one end of the connecting tube being fixedly connected to an installation head, the balloon being fitted with the connecting head, and the installation head having two symmetrically arranged installation holes.

[0006] A rotating ring is rotatably mounted on the connector head. A connecting rod is mounted on one side of the rotating ring. A slider is fixedly connected to one end of the connecting rod. A locking block is slidably mounted on the slider. Two protrusions are provided on the inner wall of the rotating ring. A straight rod is slidably mounted on the protrusions. An arc-shaped plate is fixedly connected to one end of the straight rod. An installation block is provided on the inner wall of the arc-shaped plate.

[0007] Furthermore, the mounting head has a groove, and a sealing ring is provided inside the groove.

[0008] Furthermore, a flow tube is fixedly connected to the outer circumferential surface of the rod, an indicator airbag is installed on the flow tube, the indicator airbag is fixedly connected to the corresponding end of the connecting tube, and a medical one-way valve is installed on the flow tube.

[0009] Furthermore, the connector head has an annular groove corresponding to the rotating ring, an arc groove corresponding to the slider, two locking holes on the inner wall of the arc groove, and an orientation hole corresponding to the straight rod and connected to the annular groove.

[0010] Furthermore, the slider has a slot, and part of the card block is slidably connected inside the slot. A return spring is fixedly connected between the card block and the inner wall of the slot, and the card block has an arc surface.

[0011] Furthermore, the outer surface of the rod body begins to have straight grooves corresponding to the connecting pipe.

[0012] The beneficial effects of this application are: the quick snap-fit ​​of the mounting head and the connector by the mounting block makes the installation and fixation of the connecting tube and the balloon more convenient during installation and disassembly for subsequent cleaning, thereby improving the practicality of the device and making subsequent cleaning and disinfection work more convenient. At the same time, the sealing ring makes the connection between the connector and the mounting head more airtight, preventing air leakage, ensuring that the balloon is more stable in the inflated state, and ensuring that the puncture suture device is more secure.

[0020] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0021] like Figure 1-5 As shown, this application provides a puncture and suturing device with a balloon, including a rod body 1, a balloon 2, and a connecting tube 4. One end of the connecting tube 4 is fixedly connected to an installation head 7. A connecting head 5 is installed on the balloon 2. The installation head 7 has two symmetrically arranged installation holes 8. A rotating ring 6 is rotatably installed on the connecting head 5. A connecting rod 10 is installed on one side of the rotating ring 6. One end of the connecting rod 10 is fixedly connected to a slider 11. A locking block 12 is slidably mounted on the slider 11. Two protrusions 13 are provided on the inner wall of the rotating ring 6. A straight rod 14 is slidably mounted on the protrusions 13. One end of the straight rod 14 is fixedly connected to an arc-shaped plate 15. An installation block 16 is provided on the inner wall of the arc-shaped plate 15.

[0022] like Figure 1-3 As shown, there is a groove on the mounting head 7, and a sealing ring 9 is installed inside the groove.

[0023] like Figure 1 As shown, a flow tube is fixedly connected to the outer circumferential surface of the rod 1, an indicator airbag 3 is installed on the flow tube, the indicator airbag 3 is fixedly connected to the corresponding end of the connecting tube 4, and a medical one-way valve is installed on the flow tube.

[0024] like Figure 1-5 As shown, the connector 5 has an annular groove corresponding to the rotating ring 6, and an arc groove corresponding to the slider 11. There are two locking holes on the inner wall of the arc groove, and the connector 5 has an orientation hole corresponding to the straight rod 14 and connected to the annular groove.

[0025] like Figure 1-5 As shown, the slider 11 has a slot, and part of the block 12 is slidably connected inside the slot. A return spring 17 is fixedly connected between the block 12 and the inner wall of the slot. The block 12 has an arc surface.

[0026] like Figure 1-5 As shown, straight grooves corresponding to connecting pipe 4 begin to appear on the outer surface of rod 1.

[0027] The working principle of this utility model is as follows: When needed, the mounting head 7 on the connecting tube 4 is inserted into the connecting head 5 on the balloon 2. Then, the rotating ring 6 is rotated. The rotating ring 6 drives the slider 11 to move through the connecting rod 10. The curved surface of the locking block 12 on the slider 11 is subjected to a large force, causing the curved surface to be squeezed into the slot. The rotation of the rotating ring 6 drives the protruding block 13 to move. The protruding block 13 drives the straight rod 14 to move. The straight rod 14 is restricted by the directional hole and drives the arc plate 15 to move. The two arc plates 15 are squeezed inward, so that the mounting block 16 is placed inside the mounting hole 8, thereby realizing the installation and fixation of the connecting tube 4 and the balloon 2. The connecting tube 4 is placed inside the straight groove, and the balloon 2 is installed for use.

[0028] Furthermore, the sealing ring 9 on the mounting head 7 is tightly attached to the inner wall of the connector head 5 to achieve a seal between the connecting tube 4 and the balloon 2, thus preventing air leakage;

[0029] Specifically, balloon 2 is in a deflated state. During surgery, after entering the patient's abdominal cavity along with rod 1, an external air source connected to a medical one-way valve inflates the indicator balloon 3 and balloon 2. By observing the indicator balloon 3, it is confirmed that balloon 2 is inflated to a circular expansion state. The inflated balloon seals the abdominal cavity, performing the function of preventing the puncture suture from falling off inside the abdominal cavity. At this time, the suturing surgery is performed. After the surgery, the operator connects a syringe-shaped air aspiration device to the valve port of the medical one-way valve. By pulling the syringe, the suction force generated breaks the component inside the medical one-way valve that prevents gas backflow, thereby drawing out the gas from balloon 2, causing balloon 2 to return to a deflated state and detach from the body along with rod 1. The entire surgical process is completed. Then, the rotating ring 6 is reversed, and the above steps are repeated to disassemble balloon 2, which can then be easily cleaned and disinfected.

[0030] The remaining structure of the puncture suture device can be achieved using existing technology, and will not be described in detail in this embodiment.

[0031] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
