Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a puncture device which is easy to disinfect. Background Art

[0002] With the development of medical technology, minimally invasive surgery has been praised for its advantages such as reduced trauma, less bleeding and faster recovery. The trocar serves as a portal to enter the body cavity, allowing doctors to complete surgical operations through tiny incisions, greatly reducing the trauma and risks caused by traditional open surgery.

[0003] A trocar is a surgical instrument that pierces the abdominal wall and provides a channel for other surgical instruments to enter the body cavity. It is a minimally invasive surgical instrument. The trocar is superior to traditional laparoscopic surgery in terms of minimally invasive concept and clinical effect. It is more in line with the minimally invasive concept and utilizes the natural scars remaining in the human body to reduce intraoperative incisions, alleviate postoperative pain, and minimize trauma. It is used in clinical medical operations in the Department of Cardiology to provide a drainage environment for fluids in the body cavity.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Embodiment 1

[0027] like Figure 1-7 As shown, the utility model proposes a puncture device that is easy to disinfect, including a needle cap 1, a connector 2, a puncture catheter 5 and a puncture needle 6, the needle cap 1 is detachably connected to the puncture needle 6, the connector 2 is detachably connected to the puncture catheter 5, the needle cap 1 is detachably connected to the connector 2, a sealing ring 14 is fixedly connected to the inner side of the connector 2, a first disassembly assembly for quick disassembly of the needle cap 1 is arranged on the inner side of the connector 2, the first disassembly assembly includes a first connecting rod 9 and a buckle 10, a second disassembly assembly for quick disassembly of the puncture catheter 5 is arranged on the inner side of the connector 2, the second disassembly assembly includes a catheter clamp 15 and an elastic rod 19, an air blocking valve 7 is fixedly connected to the outside of the air blocking valve 5, a valve 8 is rotatably connected to the outside of the air blocking valve 7, the valve core 16 is movably connected to the inside of the air blocking valve 7, the outside of the valve core 16 is fixedly connected to the valve 8, a groove 12 is provided inside the needle cap 1, and a first threaded rod 13 is fixedly connected to one end of the puncture needle 6 close to the needle cap 1;

[0028] The bottom of the needle cap 1 is fixedly connected with a second connecting rod 11, the inner side of the connector 2 is movably connected with the second connecting rod 11, and the second connecting rod 11 is fixedly connected with the buckle 10;

[0029] The inner side of the connector 2 is movably connected with a disassembly button 3, the outside of the disassembly button 3 is fixedly connected with a return spring 24, the end of the return spring 24 away from the disassembly button 3 is fixedly connected to a limit plate 23, the limit plate 23 is fixedly connected to the inner side of the connector 2, the disassembly button 3 is fixedly connected to the first connecting rod 9, the first connecting rod 9 is movably connected to the limit plate 23, and the first connecting rod 9 is movably connected to the inner side of the connector 2.

[0030] In this embodiment, when the medical staff needs to disinfect and disassemble the puncture device, they only need to press the disassembly button 3, and the disassembly button 3 will drive the first connecting rod 9 to move laterally to squeeze the buckle 10, and the second connecting rod 11 will be bent by squeezing the buckle 10. When the first connecting rod 9 squeezes the buckle 10 out of the inner side of the connector 2, it continues to squeeze, and the second connecting rod 11 moves upward through the slope of the buckle 10, which will quickly separate the needle cap 1 from the connector 2. At the same time, the reset spring 24 will drive the disassembly button 3 to rebound, keeping the first connecting rod 9 in its original position without affecting the subsequent installation. The interior of the groove 12 is provided with a thread, and the air blocking valve 7 is rotated. By driving the first threaded rod 13 to rotate in the groove 12, the needle cap 1 and the air blocking valve 7 can be separated. By depressing the quick-release hoop 17, the connecting block 20 is driven to rotate, thereby driving the connecting column 18 to rotate, releasing the tension on the elastic rod 19, so that the clamping block 25 is no longer tight, so that the puncture catheter 5 can be quickly detached from the catheter clamp 15. By turning the knob 21, the second threaded rod 22 is driven to rotate in the positioning ring 4, so that the positioning ring 4 can be moved to any position of the puncture catheter 5, and the positioning ring 4 can also be detached from the puncture catheter 5. The operation is simple, and medical staff can disinfect the puncture device without complicated operations.

[0031] Embodiment 2

[0033] In this embodiment, when it is necessary to inject or discharge gas, it is only necessary to rotate the valve 8. The rotation of the valve 8 drives the valve core 16 to rotate. When the hole of the valve core 16 is aligned with the air blocking valve 7, the gas can be injected or discharged to maintain the pressure balance in the surgical area and keep the field of vision clear. In an emergency, the valve 8 can be rotated so that the hole of the valve core 16 is no longer aligned with the air blocking valve 7, thereby quickly closing the gas channel to prevent accidents.
