Description

Technical Field

[0001] The utility model belongs to the field of medical auxiliary instruments, and in particular relates to a breast abscess puncture and drainage device. Background Art

[0002] Breast abscess is when the infection source invades the breast tissue through the nipple, causing infection in the breast duct, forming a suppurative tissue infection area, which is breast abscess. At present, the treatment of breast abscess mostly adopts incision and drainage, which is traumatic, slow to recover, and painful for patients.

[0003] Compared with traditional open surgery, puncture and drainage is a minimally invasive surgery that is less invasive to the body, which means less damage to breast tissue and faster healing time. Breast abscess puncture and drainage surgery has a small incision and relatively fast recovery after surgery, so patients can return to normal life and work in a shorter time. And by precisely controlling puncture and drainage, pus can be removed more effectively, reducing the risk of abscess recurrence.

[0004] Existing breast puncture and drainage devices still have some shortcomings: the puncture needle and drainage tube are used separately. The puncture needle is first inserted into the abscess site, then the opening is expanded with a skin dilator, and finally the drainage tube is inserted. This leads to repeated puncture processes, making the entire drainage process longer and increasing the risk of tissue damage. Secondly, for the fixation of the drainage tube, traditionally, the drainage tube is usually fixed by suturing it to the breast skin. This method is cumbersome to operate and causes additional pain to the patient. In addition, some existing fixation devices are cumbersome to operate and have poor fixation effects.

[0005] Therefore, the utility model provides a breast abscess puncture and drainage device. Utility Model Content

[0007] In order to achieve the above technical effects, the utility model is implemented through the following technical solutions: a breast abscess puncture and drainage device, including a puncture needle, a drainage mechanism and a fixing mechanism.

[0008] Furthermore, the drainage mechanism includes a drainage tube rotatably sleeved on the surface of the puncture needle and a drainage joint rotatably connected to the tail end of the drainage tube; the fixing mechanism includes a fixing ring sleeved on the drainage tube, a rotating ring spirally connected to the fixing ring, a fixing block slidably installed around the inside of the fixing ring, a limiting rod arranged on the fixing block, and a limiting groove arranged around the upper surface of the rotating ring; and an adhesive is provided at the bottom of the fixing ring.

[0009] Furthermore, the front end of the drainage tube is a conical structure; and the limiting groove 35 is an arc-shaped groove.

[0010] Furthermore, the drainage joint includes a drainage main pipe rotatably connected to the tail end of the drainage pipe, a cover rotatably connected to the port of the drainage main pipe, and a drainage side pipe arranged on the side of the drainage main pipe. The drainage main pipe and the drainage side pipe are only provided with a throttle valve.

[0011] Furthermore, the fixing ring is provided with sliding grooves around its interior, and a fixing block is slidably installed in the sliding grooves; the limiting rod on the fixing block is slidably connected with the limiting through groove, and a limiting blocking piece is provided on the limiting rod.

The limiting rod 34 on the fixing block 33 is slidably connected with the limiting through groove 35, and the limiting rod 34 is provided with a limiting stopper 341.

[0032] The adhesive member 4 is slidably sleeved on the drainage tube 21 , and the adhesive member 4 is made of transparent material.

[0033] Example 2

[0034] In the utility model, the specific operation steps are as follows:

[0035] The patient lies flat after receiving local anesthesia, and an ultrasonic detector is used to locate the swollen part of the breast. The puncture needle 1 is inserted into the swollen part of the patient's breast together with the drainage tube 21. After accurate positioning, the drainage joint 22 is rotated and removed from the drainage tube 21 to expose one end of the puncture needle. Then the puncture needle 1 is rotated and taken out of the drainage tube 21. The drainage joint 22 is immediately rotated and installed back on the drainage tube 21. At this time, the throttle valves on the drainage main tube 221 and the drainage side tube 223 are both in the closed state. The drainage tube 21 is externally connected to a drainage collection device (such as a drainage bag or a drainage ball). The throttle valve of the drainage main tube 221 is opened to achieve drainage of pus.

[0036] The drainage tube 21 is fixed to the breast using a fixing mechanism 3. The fixing mechanism 3 comprises a fixing ring 31 sleeved on the drainage tube 21, a rotating ring 32 spirally connected to the fixing ring 31, and a fixing block 33 slidably mounted around the inside of the fixing ring 31. An adhesive member 4 is provided at the bottom of the fixing ring 31 for fixing the device on the breast.

[0037] Working principle of the fixing mechanism: The upper surface of the rotating ring 32 is provided with limiting grooves 35 (arc-shaped grooves) around the periphery, which are slidably connected with the limiting rod 34 on the fixed block 33. When the rotating ring 32 is rotated to open, the limiting groove 35 drives the limiting rod 34 to slide along the track, so that the fixed block 33 slides linearly along the inside of the slide groove 311 of the fixed ring 31, thereby loosening the clamping of the drainage tube 21. Move the fixing device to the breast jack, and stick the adhesive 4 on the breast to achieve preliminary fixation. Rotate the rotating ring 32 in the opposite direction, so that the limiting rod 34 slides back along the track of the limiting groove 35, and the fixed block 33 slides along the outside of the slide groove of the fixed ring, thereby clamping the drainage tube 21.

[0038] After the drainage is completed, antibiotics or saline with antibiotics are injected through the drainage side tube 223 according to the patient's condition. At this time, the throttle valve of the drainage side tube 223 is opened, and the throttle valve of the drainage main tube 221 is closed. After the disinfection is completed, the throttle valve is adjusted again to discharge the disinfectant.

[0039] The utility model combines the puncture needle with the drainage tube to simplify the puncture process, reduce the risk of tissue damage and infection, and adopts a fixing mechanism that is simple and convenient to operate to clamp or loosen the drainage tube, thereby improving the convenience, flexibility and efficiency of the operation.
