Description

Technical Field

[0001] This utility model relates to the field of physiotherapy equipment technology, specifically to a laparoscopic irrigation and suction head. Background Technology

[0002] Laparoscopic irrigators are commonly used medical devices in laparoscopic surgery. Their main function is to irrigate the abdominal cavity during surgery to remove blood, bile, necrotic tissue, and other foreign bodies, maintaining a clear surgical field and thus facilitating the smooth progress of the operation. The irrigator head is the main component that delivers the irrigating fluid into the abdominal cavity and suctions blood, bile, and other foreign bodies outwards. However, most existing laparoscopic irrigator heads are tubular. When suctioning foreign bodies after irrigation, the soft tissue in the abdominal cavity is drawn in by the suction force, clogging the slots on the irrigator head and hindering the suction process. Although some laparoscopic irrigator heads on the market can expand during use to block soft tissue and prevent blockage, these heads lack a locking mechanism. During use, the expanded portion at the end requires continuous force from the medical staff to maintain its expansion, which is not only cumbersome but also causes hand fatigue for the medical staff and can negatively impact the stability of the patient's surgery. Utility Model Content

[0003] In view of the problems existing in the prior art, this utility model discloses a laparoscopic irrigation and suction head. The technical solution adopted is as follows: it includes a flow tube, a sleeve is slidably sleeved on the outside of the flow tube, one end of the flow tube is connected to one end of a three-way valve, a plurality of liquid inlet and outlet holes are opened on the side of the other end of the flow tube, a plurality of liquid inlet and outlet grooves are opened on the end face of the other end of the flow tube, the side wall of the groove on the side of one end of the flow tube and the side wall of the groove on the side of one end of the sleeve are rotatably connected to the side walls of both ends of the elastic expansion wires, a plurality of elastic expansion wires are provided, the plurality of elastic expansion wires are evenly distributed along the side walls of the flow tube and the sleeve, and a locking mechanism for locking the sleeve is installed on the flow tube and the sleeve.

[0004] As a preferred embodiment of this invention, the three-way valve is provided with an irrigation fluid inlet and an abdominal fluid outlet.

[0005] As a preferred embodiment of this utility model, the locking mechanism includes a spring, a support plate, a locking block, a locking groove, a guide groove, and a locking pin. Two support plates are provided, and the two support plates are fixedly installed on the side of the sleeve. The middle of the opposite side of the two support plates is rotatably connected to the side of the middle of the locking block. One side of the locking block is fixedly connected to one end of the spring, and the other end of the spring is fixedly connected to the side of the sleeve. The bottom of the locking pin is installed on the side of the middle of the flow tube. A guide groove is provided on the sleeve, and the locking pin is located in the guide groove. A locking groove that cooperates with the locking pin is provided on the side of the other end of the locking block.

[0007] As a preferred embodiment of this utility model, the other end of the locking block is provided with an inclined surface that cooperates with the locking pin.

[0008] The beneficial effects of this utility model are as follows: By pushing the sleeve to move, the sleeve causes the elastic expansion wire to deform, arching outward to form a cage-like structure, which blocks soft tissue and prevents the soft tissue from being sucked into the flow tube and blocking the liquid inlet / outlet hole and liquid inlet / outlet groove, thus ensuring a smooth suction process. As the sleeve moves, the locking pin on the flow tube contacts the inclined surface on the locking block, causing the locking pin to push the locking block to rotate, allowing one end of the locking block to move to the outside of the locking pin. Through the elasticity of the spring, the locking groove on the locking block locks onto the locking pin, thereby locking the sleeve. During the suction process, the elastic expansion wire can maintain its expanded state without continuous force, making it convenient to use, reducing the fatigue of medical staff, and facilitating use during surgery.

[0015] Example 1

[0016] like Figures 1 to 5 As shown, this utility model discloses a laparoscopic irrigation and suction head. The technical solution includes a flow tube 1, with a sleeve 2 slidably sleeved on the outside of the flow tube 1. One end of the flow tube 1 is connected to one end of a three-way valve 7. The three-way valve 7 is provided with an irrigation fluid inlet 8 and a peritoneal fluid outlet 9. Several liquid inlet and outlet holes 4 are opened on the side of the other end of the flow tube 1, and several liquid inlet and outlet grooves 5 are opened on the end face of the other end of the flow tube 1. The side wall of the groove on one end of the flow tube 1 and the side wall of the groove on one end of the sleeve 2 are rotatably connected to the sides of both ends of an elastic expansion wire 3. 3. Several elastic expansion wires 3 are evenly distributed along the sides of the flow tube 1 and the sleeve 2. A locking mechanism 6 for locking the sleeve 2 is installed on the flow tube 1 and the sleeve 2. The locking mechanism 6 includes a spring 61, a support plate 62, a locking block 63, a locking groove 64, a guide groove 65, and a locking pin 66. Two support plates 62 are provided, and the two support plates 62 are fixedly installed on the side of the sleeve 2. The middle part of the opposite side of the two support plates 62 is rotatably connected to the side of the middle part of the locking block 63. The side of one end of the locking block 63 is fixedly connected to one end of the spring 61, and the other end of the spring 61 is connected to the side of the sleeve 2. The sleeve 2 is fixedly connected to the side, and the locking pin 66 is installed on the side of the middle part of the flow tube 1. The sleeve 2 is provided with a guide groove 65, and the locking pin 66 is located in the guide groove 65. The other end of the locking block 63 is provided with a locking groove 64 that cooperates with the locking pin 66. The side of one end of the locking block 63 is provided with anti-slip texture 10, and the other end of the locking block 63 is provided with a bevel that cooperates with the locking pin 66. By pushing the sleeve 2 to move, the sleeve 2 pushes the elastic expansion wire 3 to deform, causing it to arch outward to form a cage-like structure, which blocks the soft tissue and prevents the soft tissue from being attracted by the flow tube 1 and blocking the flow of liquid. The orifice 4 and the liquid inlet / outlet groove 5 ensure smooth suction. As the cannula 2 moves, the locking pin 66 on the flow tube 1 contacts the inclined surface on the locking block 63, causing the locking pin 66 to push the locking block 63 to rotate. This allows one end of the locking block 63 to move to the outside of the locking pin 66. Through the elasticity of the spring 61, the locking groove 64 on the locking block 63 locks onto the locking pin 66, thus locking the cannula 2. During suction, the elastic expansion wire 3 can maintain its expanded state without constant force, making it convenient to use, reducing the fatigue of medical staff, and facilitating use during surgery.

[0017] The working principle of this invention is as follows: Connect the irrigation fluid inlet of the three-way valve 7 to the laparoscopic irrigation device, insert one end of the flow tube 1 into the abdominal cavity, and push the sleeve 2 to move towards the liquid inlet / outlet port 4. This causes the sleeve 2 to deform the elastic expansion wire 3, bending and expanding it outward to form a cage-like structure that blocks soft tissue. During the movement of the sleeve 2, the inclined surface on the locking block 63 contacts the locking pin 66. As the sleeve 2 moves, the locking pin 66 pushes the locking block 63 to rotate, causing one end of the locking block 63 to lift up and the other end to compress the spring 61. As the sleeve 2 moves, when the locking groove 64 aligns with the locking pin 66, the elasticity of the spring 61 pushes the locking block 63 to reverse, causing one end of the locking block 63 to lock onto the locking pin 66, thereby locking the sleeve 2. This allows the elastic dilatation wire 3 to maintain its cage-like structure and block soft tissue. At this time, turning the knob on the three-way valve 7 connects the flushing fluid inlet 8 to the flow tube 1, allowing the flushing fluid to flow from the inlet 8 and the three-way valve 7 into the flow tube 1. The fluid then flows into the abdominal cavity through the liquid inlet / outlet hole 4 and the liquid inlet / outlet groove 5 on the flow tube 1, flushing the abdominal cavity. After flushing, turning the knob on the three-way valve 7 connects the abdominal fluid outlet 9 to the flow tube 1, allowing the abdominal fluid to re-enter the flow tube 1 through the liquid inlet / outlet hole 4 and the liquid inlet / outlet groove 5, and then exit through the abdominal fluid outlet 9 on the three-way valve 7. After the abdominal fluid is discharged, pressing the locking block 63 near the spring 61 lifts the other end of the locking block 63. At this time, the spring dilatation wire 3, due to its restoring elasticity, exerts a thrust on the sleeve 2, causing the suction device to return to its original position. Figure 1 Once the condition is reached, the suction device can be removed from the abdominal cavity.
