[0002] At present, in many thoracic, abdominal and pelvic surgeries, including laparoscopic surgery and open surgery, it is necessary to aspirate the body fluids, blood, or flushing fluids in the cavity. The traditional suction device is usually a straight cylinder with a side suction hole on one side of the cylinder. Each time suction is performed, the liquid can be sucked into the cylinder, but at the same time, the intestinal tract, greater omentum and other tissues will also be sucked. On the one hand, this will damage the human tissue, and on the other hand, it will block the side hole, resulting in the inability to smoothly aspirate the liquid, affecting the progress of the operation.

[0024] The laparoscopic surgery suction device provided by the utility model is explained and illustrated in detail below in conjunction with the drawings in the specification.

[0025] The laparoscopic surgical suction device provided by the utility model can be connected to the suction device and the flusher at the same time, and the operation of flushing or suctioning the surgical site cavity can be performed by switching the control valve, so that the suction device has more functions and the number of instruments during the operation can be reduced. In addition, through the setting of the protective component, the suction section can be protected to prevent the intestinal tract, greater omentum and other tissues from being adsorbed onto the suction section to block the side holes when the liquid is adsorbed, thereby ensuring that the suction operation can be carried out normally and also avoiding damage to the tissues in the cavity. The following is a detailed introduction of the utility model in conjunction with specific embodiments:

[0026] like Figure 1 , Figure 2 As shown, in one embodiment, the utility model provides a laparoscopic surgical suction device, including a suction tube 1, a suction section 2 is provided at the first end of the suction tube 1, a plurality of side holes 21 are formed on the side wall of the suction section 2, and the side holes 21 are connected to the interior of the suction tube 1.

[0027] The laparoscopic surgical suction device further includes a joint assembly 3, which includes a first joint 31, a second joint 32 and a third joint 33. The first joint 31 is used to connect to the suction device, the second joint 32 is used to connect to the flusher, and the third joint 33 is used to connect to the suction tube 1. Thus, the suction tube 1 can be used for suction and flushing operations.

[0028] The connector assembly 3 also includes a control valve, which is used to control one of the first connector 31 or the second connector 32 to be connected to the third connector 33. When aspiration operation is performed, the first connector 31 is connected to the third connector 33, and when flushing operation is performed, the second connector 32 is connected to the third connector 33. Both flushing and aspiration are performed through the suction tube 1, but the two operation steps are performed independently.

[0029] The laparoscopic surgical suction device also includes a protective component, which includes a sleeve 4 that is slidably mounted on the suction tube 1. The first end of the sleeve 4 is connected to a plurality of support rods 5, and the support rods 5 are elastic rods. Optionally, the support rods 5 are made of an elastic metal material, such as 301 steel or 304 steel. The first end of the support rod 5 is connected to the first end of the sleeve 4, and the second end of the support rod 5 is connected to the free end of the suction section 2. The plurality of support rods 5 are evenly distributed along the circumference of the suction section 2. Optionally, four, five, six or more support rods 5 can be provided. The sleeve 4 has a first working position and a second working position by sliding. In the first working position, as Figure 1 As shown, the sleeve 4 is away from the suction section 2, and the support rod 5 is in a straight state, preferably being able to fit on the suction section 2; in the second working position, as shown Figure 2 As shown, the sleeve 4 is close to the attraction section 2, and the support rod 5 is in a bent state, forming an outwardly convex protective structure radially outward of the attraction section 2, which can prevent the intestinal tract, greater omentum and other tissues from approaching the attraction section 2 and blocking the side hole 21 of the attraction section 2.

[0030] In one embodiment, Figure 1 As shown, the control valve includes a first valve 61 disposed on the first connector 31, and a second valve 62 disposed on the second connector 32, wherein one of the first valve 61 and the second valve 62 is closed and the other is opened, and the first valve 61 and the second valve 62 are independently disposed and independently controlled. In another embodiment, as Figure 2 As shown, the control valve is a three-way valve 6, and the three connectors of the three-way valve 6 are respectively connected to the first connector 31, the second connector 32 and the third connector 33. The three-way valve 6 controls one of the first connector 31 and the second connector 32 to communicate with the third connector 33. The control valve can adopt any method that can realize the control of the first connector 31 and the second connector 32 to independently communicate with the third connector 33, and the specific structure of the control valve is not limited here.

[0031] In one embodiment, a guide block is formed on the outer wall of the suction tube 1, and a guide groove is formed on the inner wall of the sleeve 4. The guide groove extends along the length direction of the sleeve 4, and the guide block is slidably embedded in the guide groove. The guide block and the guide hole are slidably matched to guide and limit the sliding of the sleeve 4, thereby preventing the sleeve 4 from rotating relative to the suction tube 1. Optionally, the guide block and the guide groove can be provided in one or more groups.

[0032] Optionally, a fixing clip 41 is provided at the second end of the sleeve 4, and the fixing clip 41 can be clamped on the outer wall of the suction tube 1. The fixing clip 41 is made of elastic material, and its clamping end is pressed on the outer wall of the suction tube 1 under the action of elastic force. When the sleeve 4 slides to the first working position or the second working position, the fixing clip 41 is pressed on the outer wall of the suction tube 1 to provide a certain resistance, so that the sleeve 4 remains in the first working position or the second working position.

[0033] Furthermore, a card slot is provided on the outer wall of the suction tube 1. When the sleeve 4 is in the second working position, the clamping end of the fixed clip 41 slides into the card slot, which can more effectively fix the sleeve 4 in the second working position, so that the suction or flushing operation can be carried out smoothly. Optionally, two card slots can be provided, so that when the sleeve 4 is in the first working position, the clamping end of the fixed clip 41 can also slide into one of the card slots. In this embodiment, the side wall of the card slot is arc-shaped, and the clamping end of the fixed clip is bent into an arc shape, so that the clamping end can easily slide into or out of the card slot.

[0034] The laparoscopic surgical suction device provided by the utility model is in the first working position before use. When in use, the suction section 2 is inserted into the cavity of the surgical site, and then the suction tube 1 is pulled or the sleeve 4 is pushed to slide the sleeve 4 to the second working position, and the support rod 5 plays a protective role for the suction section 2. Then, the first connector 31 is connected to the suction device, and the second connector 32 is connected to the flusher, and then the conduction relationship between the first connector 31, the second connector 32 and the third connector 33 is controlled by the control valve assembly, so as to perform flushing or liquid suction operations.
