Description

Technical Field

[0001] The utility model relates to the technical field related to medical devices, in particular to an aspirator structure for single-port thoracoscopic surgery. Background Art

[0002] Single-port thoracoscopic surgery requires fewer incisions. The entire operation only requires a small incision of 3-4 cm. The surgical instruments need to be inserted into the chest cavity through this small incision. This reduces the number of instruments entering the chest cavity through the single-port thoracoscopic surgery, makes the incision smaller, reduces trauma, reduces hospitalization time, relieves patients' pain, and speeds up postoperative recovery.

[0003] During single-port thoracoscopic surgery, an aspirator is required to absorb the accumulated fluid. At the same time, in order to improve the suction effect, the aspirator head will be rotated 360° during the operation so that the accumulated fluid near the surgical site can be completely sucked out.

[0004] Chinese patent authorization announcement number: CN220025725U, authorization announcement date 2023-11-17, discloses a suction catheter, including a suction head and a catheter body for communicating with a negative pressure device, wherein: the suction head is fixed to the end of the catheter body, and a drainage cavity is provided in the suction head, and the drainage cavity is connected to the inner cavity of the catheter body; the outer diameter of the end of the suction head connected to the catheter body is greater than the outer diameter of the catheter body, and the outer diameter of the suction head gradually decreases in the direction away from the catheter body, and the end of the suction head away from the catheter body and the side wall of the suction head are provided with holes, and the holes are all connected to the drainage cavity. The disadvantage of the above patent is that when the suction catheter is rotated, the hose connected to the negative pressure device at its tail will bend, causing the hose to be blocked, affecting its suction effect.

[0005] In summary, there is a need for a suction device structure for single-port thoracoscopic surgery that can avoid blockage. Utility Model Content

[0006] The utility model aims to overcome the deficiency in the prior art that when the suction catheter is rotated, the hose connected to the negative pressure device at its tail end may be bent, resulting in clogging of the hose and affecting its suction effect. The utility model provides an aspirator structure for single-port thoracoscopic surgery that can avoid clogging.
