Abstract
Description
Technical Field
[0001] This utility model relates to the field of laparoscopic minimally invasive suction device technology, specifically a laparoscopic minimally invasive suction device. Background Technology
[0002] As is well known, minimally invasive surgery, represented by laparoscopic techniques, has become an important direction in medical development, and most abdominal organ surgeries can now be performed laparoscopically. During surgery, due to the cutting and separation of tissues, fat liquefaction and damage to small blood vessels occur, inevitably requiring the use of a suction device to remove surgical oozing and fluid. In laparoscopic surgery, the suction device is one of the most important instruments. The suction device is mainly used to remove bleeding, exudate, pus, and contents from thoracic organs during surgery, making the surgical field clear and reducing the chance of contamination. Currently, the suction devices used in laparoscopic surgery are long tubular types.
[0003] Existing laparoscopic minimally invasive suction devices are not convenient for positioning long suction rods when suctioning patients. Furthermore, the small incisions can cause hand fatigue for surgeons during prolonged use, complicating the procedure. Therefore, we propose a laparoscopic minimally invasive suction device to solve these problems. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-3This utility model discloses a laparoscopic minimally invasive aspirator, comprising a laparoscopic aspirator 1, a circular groove block 2 in the middle of the laparoscopic aspirator 1, and an arc-shaped positioning ring 3 in the middle of the circular groove block 2. The arc-shaped positioning ring 3 cooperates with the circular groove block 2 in a sliding fit, allowing the circular groove block 2 to slide along the arc-shaped positioning ring 3. A fixing bolt is provided at the left end of the arc-shaped positioning ring 3, and a telescopic rod 4 is provided at the bottom end of the arc-shaped positioning ring 3. The telescopic rod 4 is marked with a telescopic length to facilitate the viewing of the telescopic length. A bed board clamping plate 5 is provided at the bottom end of the telescopic rod 4. The bottom of the plate 5 is provided with a threaded fixing clamp 6, which cooperates with the bed plate clamping plate 5. The threaded fixing clamp 6 and the bed plate clamping plate 5 are connected by a thread, so that the threaded fixing clamp can be adjusted along the bed plate clamping plate 5. The edges of the laparoscopic aspirator 1, the circular groove block 2, the arc positioning ring 3, the telescopic rod 4, the bed plate clamping plate 5 and the threaded fixing clamp 6 are all rounded, so that the laparoscopic minimally invasive aspirator will not scratch the user when using it. When the laparoscopic minimally invasive aspirator is used to aspirate the patient, it is easy to position the long suction rod. During long-term use, if the surgeon's hand becomes tired, he can loosen the laparoscopic aspirator 1 without affecting the micro-incision.
[0022] In summary, when using this laparoscopic minimally invasive aspirator, the aspirator 1 is first fixed inside the minimally invasive incision. The aspirator 1 is then clamped onto the bed board using the bed board clamping plate 5 and the threaded fixing clamp 6. The aspirator can then be extended or retracted to a suitable height using the telescopic rod 4. After fixing, the angle of the aspirator 1 can be finely adjusted using the clamping arc positioning ring 3 and the circular groove block 2. It can also be secured with fixing bolts. This laparoscopic minimally invasive aspirator facilitates the positioning of the long suction rod when aspirating the patient. During prolonged use, if the surgeon experiences hand fatigue, the aspirator 1 can be released without affecting the minimally invasive incision. Therefore, this laparoscopic minimally invasive aspirator offers better performance.

The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.
