Description

Technical Field

[0001] This utility model belongs to the field of puncture device technology, and in particular relates to a laparoscopic puncture device. Background Technology

[0002] A laparoscopic trocar is a medical device mainly used during laparoscopic examinations and surgeries to puncture the abdominal wall tissue and establish a working channel for abdominal surgery. This trocar usually contains several trocars of different sizes to meet the needs of different laparoscopic surgeries for multiple trocars of different sizes. At the same time, it can also ensure that endoscopic instruments of different sizes can enter the abdomen and be operated through the working channel established by the trocar, thus facilitating the surgeon's use.

[0003] The following problems exist with the laparoscopic trocars currently available on the market:

[0004] 1. Traditional laparoscopic trocars are usually used with endoscopic instruments of different sizes. However, when the trocar remains the same but the size of the endoscopic instrument changes, the endoscopic instrument cannot be well matched with the inner diameter of the trocar. This causes the endoscopic instrument to shake to varying degrees inside the trocar during the operation, requiring the surgeon to maintain a high degree of stability. The trocar cannot fix the endoscopic instrument, resulting in poor stability during use.

[0005] 2. Most laparoscopic trocars are fixed directly to the patient's abdomen during use, with the trocar inserted into the puncture site. This single-fixation method cannot ensure the stability of the trocar during long-term use. If the surgeon's operation is too large, the trocar is prone to displacement or being pulled out, making it inconvenient to use. Utility Model Content

[0026] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a laparoscopic trocar.

[0027] like Figures 1-5 As shown, a laparoscopic trocar of this utility model includes a trocar cannula 1 and a trocar cone 2. The trocar cone 2 is located inside the trocar cannula 1. A channel platform 12 is installed at the bottom of the trocar cannula 1. A rubber wheel 18 is located at the bottom of the channel platform 12. A support plate 14 is fixedly connected to the bottom of the channel platform 12. A right-angle plate 21 is fixedly connected to the back of the support plate 14. A rotating shaft frame 17 is connected to the side of the rubber wheel 18 via a rotating shaft. A movable rod 16 is located on the back of the rotating shaft frame 17. The movable rod 16 passes through the support plate 14 and the right-angle plate 21. A fixing plate 19 is fixedly connected to the outside of the movable rod 16. Due to the structure of the fixing plate 19, it is fixed to the outside of the movable rod 16 and is used to apply pressure to a spring 20, allowing the rubber wheel 18 to engage well with the spring 20. In use, a spring 20 is sleeved on the outside of the movable rod 16. One end of the spring 20 is fixedly connected to a fixing plate 19, and the other end of the spring 20 is fixedly connected to a right-angle plate 21. By adding four sets of rubber wheels 18 to the top of the channel platform 12, and the tail end of the rubber wheels 18 is supported by the spring 20, when the surgeon uses the trocar, when different sizes of endoscopic instruments are inserted into the trocar cannula 1, the four sets of rubber wheels 18 will hold the endoscopic instruments. Under the elastic force of the spring 20, different sizes of endoscopic instruments will be held by the rubber wheels 18. When the endoscopic instruments are pulled back and forth, the rubber wheels 18 will rotate due to friction, thus achieving the effect of not affecting the use of the endoscopic instruments.
