Description

Technical Field

[0001] The utility model relates to the technical field of trocar cleaning, in particular to a laparoscopic trocar cleaning device. Background Art

[0002] During laparoscopic surgery, multiple 5-12mm holes are made in the abdominal / chest wall. A trocar, or poke card, is placed through these holes. One end of the trocar is inserted into the skin, while the other end is exposed on the skin surface. Surgical instruments and the lens of the laparoscope pass in and out of the abdominal / thoracic cavity through the trocar to perform various operations. After use, blood will accumulate in the internal channel (lumen) of the trocar. If it is not cleaned, it will become dirty and accumulate blood. The lens of the laparoscope / thoracoscope will be hit by the blood when passing through, causing the lens to blur and affecting the surgical operation.

[0003] Currently, the most common method for cleaning trocars is to use curved surgical forceps to hold a gauze strip and insert it into the lumen of the trocar for wiping. However, due to the inherent structural problems of curved surgical forceps, wiping with the gauze strip is difficult to operate and difficult to reach the inner wall of the lumen at the distal end of the trocar (the end of the trocar located inside the patient), making it difficult to clean the lumen at the distal end of the trocar. Furthermore, this cleaning method can occasionally damage the sealing valve on the outside or inside of the trocar or push the sealing valve along the trocar into the patient's abdominal or thoracic cavity, posing a safety hazard.

[0004] Chinese patent "CN219253535U" discloses a card puncture cleaning device, comprising a card puncture core and a cleaning brush. The card puncture core comprises a cap and a core rod. The upper end of the core rod is a round rod fixedly connected to the cap, while the middle and lower ends of the core rod are cross-shaped rods. The cleaning brush is cylindrical, with a cross-shaped groove axially defined within the brush that mates with the cross-shaped rod. The brush slides over the middle and lower ends of the core rod, and the outer wall of the brush slides over the inner wall of the card puncture. The cleaning brush comprises four connecting ribbons and four cleaning brush strips, which are sequentially connected to form a cylindrical body with a cross-shaped cavity axially defined that mates with the cross-shaped rod. By attaching the cleaning brush to the middle and lower portion of the core rod of the puncture device, this patent facilitates cleaning of the inner wall of the puncture device. This addresses the problem with prior art surgical curved forceps, which, due to their inherent structural limitations, make cleaning the distal lumen of the puncture device difficult and can compromise the seal of the card puncture device. However, the main function of the puncture device is puncture. It is very troublesome to put on the cleaning brush after puncture and then disassemble the puncture device. It may affect the puncture function of the puncture device during abdominal surgery. Utility Model Content

[0020] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0021] Example 1

[0022] refer to Figure 1-2 A laparoscopic trocar cleaning device includes a cap 1 and a shaft 2. The cap 1 is connected to the shaft 2 via a connecting structure. The cap 1 facilitates the insertion and removal of the shaft 2 from the trocar. The shaft 2 is made of a water-absorbing material. Furthermore, the shaft 2 is made of a sponge, cotton strips, or other water-absorbing material, capable of absorbing blood and water within the trocar. The outer wall of the shaft 2 conforms to the inner wall of the trocar. Furthermore, the outer diameter of the shaft 2 is slightly larger than the inner diameter of the trocar. Due to its material, the shaft 2 is deformable and can pass through the trocar to clean the inner wall of the trocar, preventing the laparoscope lens from being contaminated. The connecting structure includes a first connecting column 3 installed on the cap head 1 and a second connecting column 4 connected to one end of the rod body 2. The cap head 1 and the first connecting column 3 can be integrally formed. The first connecting column 3 is provided with an internal threaded hole, and the second connecting column 4 is provided with an external thread. The first connecting column 3 is threadedly connected to the external thread of the second connecting column 4 through the internal threaded hole; or the first connecting column 3 is provided with an external thread, and the second connecting column 4 is provided with an internal threaded hole, and the first connecting column 3 is threadedly connected to the internal threaded hole of the second connecting column 4 through the external thread; or the first connecting column 3 and the second connecting column 4 are connected by a snap buckle; the cap head 1 is connected to the second connecting column 4 of the rod body 2 through the first connecting column 3, so that the rod body 2 can be disassembled and replaced. Both ends of the rod body 2 are equipped with fixing covers 5. The two fixing covers 5 can fix the two ends of the rod 6 body 2. The second connecting column 4 is installed on the fixing covers 5. Due to the deformable material of the rod body 2, the outer diameter of the fixing cover 5 can be smaller than the outer diameter of the rod body 2. The fixing cover 5 has a better effect of fixing the two ends of the rod 6 body 2. At the same time, it can prevent the fixing cover 5 from damaging the sealing valve outside or inside the puncture device or pushing the sealing valve along the puncture device into the patient's abdominal cavity / thoracic cavity; at the same time, by setting up the rod body 2 separately, it is possible to clean the lumen at the distal end of the puncture device without being put on the puncture device core and will not affect the puncture function of the puncture device core.

[0023] Example 2

[0024] refer to Figure 3-4 A laparoscopic trocar cleaning device includes a cap 1 and a shaft 2. The cap 1 is connected to the shaft 2 via a connecting structure. The cap 1 facilitates the insertion and removal of the shaft 2 from the trocar. The shaft 2 is made of a water-absorbing material. Furthermore, the shaft 2 is made of a sponge, cotton strips, or other water-absorbing material, capable of absorbing blood and water within the trocar. The outer wall of the shaft 2 conforms to the inner wall of the trocar. Furthermore, the outer diameter of the shaft 2 is slightly larger than the inner diameter of the trocar. Due to its material, the shaft 2 is deformable and can pass through the trocar to clean the inner wall of the trocar, preventing the laparoscope lens from being contaminated.

[0025] The connection structure includes a fixing rod 6, which is connected to the cap 1. The cap 1 and fixing rod 6 can be integrally formed. The fixing rod 6 can pass through the rod body 2 and connect to the rod body 2. Specifically, the rod body 2 can be attached to the fixing rod 6 using Velcro or glue, or it can be fixed to the fixing rod 6 using a snap fastener. Other fixing methods that can achieve the fixing rod 6 and the rod body 2 are also acceptable. A fixing seat 7 is mounted on the fixing rod 6 and connected to the rod body 2. Due to the deformable material of the rod body 2, the outer diameter of the fixing seat 7 can be smaller than that of the rod body 2, thereby effectively securing the rod body 2 with the fixing cap 5. Furthermore, by providing the rod body 2 separately, the distal lumen of the puncture device can be cleaned without being placed on the puncture device core, without affecting the puncture function of the puncture device core. The working principle of the present utility model is that after the puncture device core is punctured and the puncture device is removed, the rod body 2 is inserted into the puncture device to absorb blood and liquid in the puncture device and clean the inner wall of the puncture device.
