Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically a miniature irrigation suction device. Background Technology

[0002] Irrigation and suction devices are indispensable medical equipment in minimally invasive surgery. They are mainly used for cleaning the surgical area and clarifying the surgical field. Fluid is delivered to the surgical area through tubing to flush away blood, tissue debris, and other contaminants, keeping the surgical area clean; and waste fluid and excess material in the surgical area are promptly suctioned out through tubing to prevent contamination and interference, ensuring the smooth progress of the surgery.

[0003] Existing irrigation and aspiration devices have a large diameter. For minimally invasive and simple surgeries, or for less difficult small sampling surgeries or pediatric surgeries, if a trocar larger than 5mm is used to establish a surgical channel, the resulting wound will be large and the postoperative recovery will be slow. If a trocar larger than 5mm is not used, the existing irrigation and aspiration devices are difficult to use. Utility Model Content

[0004] The purpose of this invention is to provide a miniature irrigation and suction device, which has a simple structure, is easy to use, does not require the use of a puncture instrument to establish a surgical channel, and produces a small wound, which is conducive to postoperative recovery.

[0005] The objective of this utility model is achieved through the following technical solution: A miniature flushing and suction device includes a handle, a flushing tube, and a suction tube. The handle has a cavity, and both the flushing tube and the suction tube are connected to the cavity. A flushing switch for controlling the on / off state is installed at the connection between the flushing tube and the cavity, and a suction switch for controlling the on / off state is installed at the connection between the suction tube and the cavity. The front end of the grip is connected in sequence to a tube connector and an outer sheath tube; The outer sheath includes a tube body and a connector fixedly sleeved on the outer wall of the rear end of the tube body. The connector is fixed to the front end of the tube joint.

[0006] Compared with the prior art, the advantages of this utility model are: 1. By setting up an outer sheath and connector, the outer sheath can be directly punctured into the patient's body without relying on a puncture instrument larger than 5mm to establish a surgical channel, thus reducing the wound and improving the speed of postoperative recovery; and in conjunction with the irrigation tubing, irrigation switch, suction tubing and suction switch, effective cleaning of the surgical area and drainage of waste fluid can be achieved.

Detailed Implementation

[0009] The present invention will now be described in detail with reference to the accompanying drawings and embodiments: like Figure 1-3 The image shown is a schematic diagram of an embodiment of a miniature flushing aspirator provided by this utility model: A miniature flushing and suction device includes a handle 510, a flushing tube 520, and a suction tube 530. The handle 510 has a cavity, and both the flushing tube 520 and the suction tube 530 are connected to the cavity. A flushing switch 540 for controlling the on / off state is installed at the connection between the flushing tube 520 and the cavity, and a suction switch 550 for controlling the on / off state is installed at the connection between the suction tube and the cavity. The front end of the grip 510 is sequentially connected to a tube connector 560 and an outer sheath tube 100; The outer sheath tube 100 includes a tube body 101 and a connector 102 fixedly sleeved on the outer wall of the rear end of the tube body 101. The connector 102 is fixed to the front end of the tube joint 560.

[0010] It should be noted that the multi-purpose non-destructive tissue suction cup device disclosed in patent publication number CN220530142U includes a handle 510, a rinsing tube 520, a suction tube 530, a rinsing switch 540, and a suction switch 550. The handle 510, the rinsing tube 520, the suction tube 530, the rinsing switch 540, and the suction switch 550 are all prior art, so they will not be described in detail here.

[0011] The inner wall of the pipe fitting 560 is provided with an internal thread, and the outer wall of the front end of the handle 510 is provided with an external thread that mates with the internal thread. The pipe fitting 560 is threadedly locked to the front end of the handle 510. The inner wall of the pipe joint 560 is also provided with an installation step 561, which is located on the front side of the internal thread. The front end of the handle 510 abuts against the installation step 561.

[0012] A sealing ring 570 is provided between the front end of the grip 510 and the mounting step 561.

[0013] The pipe fitting 560 is funnel-shaped with a front port diameter smaller than the rear port diameter.

[0014] The rear end of the flushing pipeline 520 is connected to a puncture head 521, which is used to puncture the sealing of the flushing fluid container, such as a saline bag or a saline medicine bottle; the flushing pipeline 520 is also equipped with a flow stop clamp 522, which is used to temporarily control the flow of flushing fluid during the flushing process.

[0015] The rear end of the suction pipe 530 is provided with a suction connector 531, which is used to connect to an external negative pressure device.

[0016] The front end of the pipe fitting 560 is fixed with a nut 200, and the rear end of the connector 102 is provided with an external thread. The connector 102 is threadedly connected to the nut 200 through the external thread.

[0017] The tube body 101 is made of metal, and the connector 102 is made of plastic. The connector 102 is connected to the rear end of the tube body 101 by injection molding.

[0018] The outer diameter of the tube 101 is 1.5mm to 2.5mm, preferably 1.6mm, 1.8mm, 2.0mm, 2.2mm, or 2.4mm.

[0019] The general method of using this utility model is as follows: Before the operation, the puncture head 521 of the irrigation tubing 520 is inserted into the irrigation fluid container, such as a saline bag or saline bag bottle, and the suction connector 531 of the suction tubing 530 is connected to an external negative pressure device. The surgeon holds the handle 510 and inserts the outer sheath 100 into the patient's body through the puncture site. This eliminates the need for a trocar to create a surgical channel, thus reducing the size of the incision. Subsequently, the surgeon operates the irrigation switch 540 or the suction switch 550 as needed to deliver irrigation fluid to the surgical area for rinsing, or to suction out waste fluid and excess material from the surgical area.

[0020] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
