[0002] As we all know, during general surgery, the surgical wound needs to be flushed to remove blood, tissue fragments and other impurities to ensure the cleanliness and visibility of the surgical area. Sterile liquids such as saline or alcohol solution are usually used for flushing to keep the surgical wound moist and clean.

[0003] After searching, a Chinese patent disclosed a general surgery flushing device, and its application publication number is CN117815479B. This patent has the function of accurately adjusting the flushing water flow according to the needs of the operation to meet the flushing needs under different surgical conditions, thereby improving the efficiency and accuracy of surgical flushing, facilitating the smooth progress of surgical operations, and reducing the occurrence of surgical complications.

[0004] In general surgery, effective flushing and waste fluid suction are crucial to the smooth progress of the operation. Existing surgical flushing devices have many shortcomings in terms of flushing head angle adjustment and waste fluid suction.

The position of the flushing and suction mechanism can be fine-tuned by stretching the elastic rope, which further improves the adjustment accuracy and flexibility of the flushing structure, allowing doctors to make fine adjustments according to surgical needs.

[0012] The present invention is further configured as follows: a stud is welded on one side of the moving rod, and the other side of the stud extends to the outside of the fixing tube, a fixing sleeve is threadedly connected to the surface of the stud, and the fixing sleeve is in close contact with the inner wall of the fixing tube on one side thereof.

[0013] By adopting the above technical solution, the fixing ability of the fine-tuning mechanism is enhanced through the threaded connection of the stud and the fixing sleeve, ensuring that the moving rod will not be displaced by external force during the flushing and suction operations, ensuring the stability and reliability of the fine-tuning effect, and improving the stability of the device during the operation.

[0014] The present invention is further configured as follows: the side of the fixed block away from the flexible flushing pipe is bolted with two mounting plates, and a pressure rod is rotatably arranged between the opposite sides of the two mounting plates, and the other end of the pressure rod is rotatably connected to the extrusion plate.

[0015] By adopting the above technical solution, the diameters of the flexible irrigation tube and the flexible suction tube can be adjusted through the design of the fixed block, the pressure rod and the extrusion plate, so that the doctor can control the flow rate of the irrigation fluid according to the needs of the operation.

[0016] The present invention is further configured as follows: the pushing assembly includes a mounting block, the mounting block is bolted between one side close to two mounting plates, the mounting block is slidably arranged on the surface of the guide rod, and the front and rear sides of the mounting block away from the mounting plate are bolted with telescopic rods, the right side of the guide rod is bolted with a positioning plate, and the telescopic rod is bolted to the side close to the positioning plate, a push plate is sleeved on the right side of the guide rod surface, and the front and rear sides of the push plate away from the positioning plate are bolted with connecting rods, the other end of the connecting rod is sleeved on the surface of the telescopic rod, and the push plate contacts the side close to the adjustment assembly.

[0017] By adopting the above technical solution, by setting up a pushing component, the push plate can be pushed to move by the telescopic rod, so that the mounting block pushes the fixed block and other structures on the right side to move on the surface of the guide rod, thereby making the fixed block and other structures on the right side move to the left side, so that the flexible flushing tube and the flexible suction tube can change the tube diameter, so that it gradually deforms from a round shape to a flat shape, which can not only adjust the flow rate, but also change the range of flushing and suction, and the synchronous movement of the connecting rod and the push plate can simultaneously push the movement of the adjustment component, so that the adjustment component can follow the deformation of the flexible flushing tube and the flexible suction tube and synchronously adjust the flow rate of waste liquid suction.

[0021] By adopting the above technical solution, by setting up a flushing liquid supply and waste liquid collection structure, according to the surgical requirements, the required flushing liquid is selected and the usage flow rate is adjusted by controlling the solenoid valve. Different flushing liquids are gathered in the manifold and enter the mixing mechanism for mixing. The mixed flushing liquid passes through the connecting pipe and enters the flushing structure for flushing operation under the action of the liquid pump, while the waste liquid enters the waste liquid collection box through the flexible suction tube.

[0023] By adopting the above technical solution, a mixing mechanism is set up. When the flushing liquid flows through the mixing mechanism, the electric heating wire heats the flushing liquid to ensure that the temperature of the flushing liquid is appropriate and reduce stimulation to the tissue. At the same time, when the flushing liquid flows in the main pipe, it is diverted and mixed by the diverter plate. After spiral flow, the flushing liquid is heated while different components are fully mixed, ensuring that the flushing liquid reaches the ideal temperature and component uniformity, providing a more suitable flushing liquid for surgery.

[0024] The present invention is further configured as follows: the waste liquid collection box and the top of the liquid pump are respectively connected with a collection pipe and a supply pipe, and the collection pipe and the supply pipe are respectively connected with the flexible suction tube and the flushing cavity.

[0032] Among them, the fine-tuning mechanism 37 includes a ring 371, which is sleeved on the surface of the bottom connecting tube 35, and the top of the ring 371 is annularly bolted with several fixed tubes 372, and a moving rod 373 is slidably arranged inside the fixed tube 372, and a moving block 374 is bolted on the top of the moving rod 373, and an elastic rope 375 is arranged on the inner wall of the moving block 374, and the elastic rope 375 is located inside the bottom connecting tube 35, and the other end of the elastic rope 375 extends to the inside of the flushing and suction mechanism 36 and is connected thereto.

[0035] Among them, the pushing component 366 includes a mounting block 366a, which is bolted between the sides close to the two mounting plates 10, and the mounting block 366a is slidably set on the surface of the guide rod 365, and the front and rear sides of the mounting block 366a away from the mounting plate 10 are bolted with telescopic rods 366b, the right side of the guide rod 365 is bolted with a positioning plate 366c, and the side of the telescopic rod 366b close to the positioning plate 366c is bolted to it, the right side of the surface of the guide rod 365 is sleeved with a push plate 366d, and the front and rear sides of the push plate 366d away from the positioning plate 366c are bolted with a connecting rod 366e, the other end of the connecting rod 366e is sleeved on the surface of the telescopic rod 366b, and the side of the push plate 366d close to the adjustment component 367 is connected to it. Contact, by setting up a pushing component 366, the push plate 366d can be pushed to move by the telescopic rod 366b, so that the mounting block 366a pushes the fixed block 363 and other structures on the right to move on the surface of the guide rod 365, thereby making the fixed block 363 and other structures on the right move to the left, so that the flexible flushing tube 361 and the flexible suction tube 362 can change the tube diameter, so that it gradually deforms from a round shape to a flat shape, which can not only adjust the flow rate, but also change the range of flushing and suction, and through the synchronous movement of the connecting rod 366e and the push plate 366d, it can simultaneously push the adjustment component 367 to move, so that the adjustment component 367 can follow the deformation of the flexible flushing tube 361 and the flexible suction tube 362 and synchronously adjust the flow rate of waste liquid suction.

[0036] The adjusting assembly 367 includes two end covers 367a, and a storage capsule 367b is arranged between the surfaces of the two end covers 367a, and the storage capsule 367b is connected to the guide rod 365. A return spring 367c is arranged in an annular shape between the opposite sides of the two end covers 367a, and the side of the end cover 367a close to the push plate 366d is connected to it.

By setting the adjusting assembly 367, when the push plate 366d pushes the right end cover 367a to move, it will synchronously squeeze the storage capsule 367b and make The return spring 367c contracts, and due to the deformation of the storage bladder 367b, the gas stored inside it can enter the guide rod 365 and be synchronously transmitted to the regulating tube 367d, thereby expanding the expansion bladder 367e, and the expansion size of the expansion bladder 367e is proportional to the degree of deformation of the flexible flushing tube 361 and the flexible suction tube 362. Therefore, through the expansion and contraction of the bladder 367e, the flow rate of waste liquid suction can be synchronously adjusted following the deformation of the flexible flushing tube 361 and the flexible suction tube 362 to avoid excessive suction. When the push plate 366d releases the squeeze on the end cover 367a, the return spring 367c restores the storage bladder 367b to its original state.

[0037] Working principle of this embodiment: when it is necessary to adjust the flushing angle of the flushing structure 3, the output shaft 6 can be driven by the external driving motor to drive the driving gear 5 to rotate, and the driven gear 4 can be meshed with the driving gear 5 to drive the top connecting tube 35 to rotate, so that the ball socket 32 ​​rotates in the protective tube 31. When the ball socket 32 ​​rotates, the movable block 39 can be driven to move along the spiral track 38 through the arc rod 310. With the gradual movement of the movable block 39 and the gradual expansion of the outer diameter of the spiral track 38, the arc rod 310 and the fixed ring 311 can drive the ball head 33 to change a certain angle in the ball socket 32, so as to achieve flushing and The purpose of preliminary adjustment of the angle of the suction mechanism 36 is that when it is necessary to fine-tune the angle of the flushing and suction mechanism 36, the corresponding moving rod 373 can slide in the fixed cylinder 372, and push the moving block 374 to move along the surface of the bottom connecting tube 35, and simultaneously stretch the elastic rope 375. The position of the flushing and suction mechanism 36 can be fine-tuned by stretching the elastic rope 375; the flushing liquid after the preliminary adjustment and fine-tuning of the angle enters the flushing structure 3 through the holding tube 14, and reaches the flushing and suction mechanism 36 along the flexible tube 34, the connecting tube 35 and the flexible flushing tube 361. During the flushing process, the flushing liquid flows from the flexible flushing tube 361 and the flexible suction tube 361. The opening between the tubes 362 sprays out to flush the surgical site, and the flexible suction tube 362 absorbs the waste liquid after flushing; during the flushing process, the telescopic rod 366b can push the push plate 366d to move, so that the mounting block 366a pushes the fixed block 363 and other structures on the right side to move on the surface of the guide rod 365, so that the fixed block 363 and other structures on the right side move to the left, so that the flexible flushing tube 361 and the flexible suction tube 362 can change the tube diameter, so that it gradually deforms from a round shape to a flat shape, which can not only adjust the flow rate, but also change the scope of flushing and suction, and the synchronous movement of the connecting rod 366e and the push plate 366d can It simultaneously pushes the right end cover 367a to move, and synchronously squeezes the storage bladder 367b and contracts the return spring 367c. The deformation of the storage bladder 367b allows the gas stored inside to enter the guide rod 365 and be synchronously transmitted to the regulating tube 367d, thereby expanding the expansion bladder 367e, and the expansion size of the expansion bladder 367e is proportional to the degree of deformation of the flexible flushing tube 361 and the flexible suction tube 362. Therefore, through the expansion and contraction of the bladder 367e, the flow rate of waste liquid suction can be synchronously adjusted following the deformation of the flexible flushing tube 361 and the flexible suction tube 362 to avoid excessive suction.

Reference Figure 7-8A general surgical flushing device also includes a flushing liquid supply and waste liquid collection structure 2, wherein the flushing liquid supply and waste liquid collection structure 2 includes a liquid storage unit 21, the liquid storage unit 21 is arranged at the rear side of the main body shell 1, and a plurality of solenoid valves 22 are arranged on the front side of the liquid storage unit 21, a manifold 23 is connected between the front sides of the plurality of solenoid valves 22, and a mixing mechanism 24 is connected to the front side of the manifold 23, a connecting pipe 25 is connected to the front side of the mixing mechanism 24, and a liquid pump 26 is connected to the front side of the connecting pipe 25, and a waste liquid collection box 27 is bolted to the bottom of the liquid pump 26, and the waste liquid collection box 27 The front side is connected with a negative pressure pump 28. By setting a flushing liquid supply and a waste liquid collection structure 2, the required flushing liquid is selected and the usage flow rate is adjusted by controlling the solenoid valve 22 according to the surgical requirements. Different flushing liquids are collected in the manifold 23 and enter the mixing mechanism 24 for mixing. The mixed flushing liquid passes through the connecting pipe 25 and enters the flushing structure 3 for flushing operation under the action of the liquid pump 26. The waste liquid enters the waste liquid collection box 27 through the flexible suction tube 362. The negative pressure pump 28 provides power for the collection of waste liquid, ensures the effective collection of waste liquid, and makes the entire flushing and waste liquid collection process more systematic and efficient.

[0039] The mixing mechanism 24 includes a fixed tube 241, which is connected to the manifold 23 and the connecting tube 25 respectively. A main tube 242 is arranged inside the fixed tube 241. A cavity is formed between the main tube 242 and the fixed tube 241, and a heating wire 243 is spirally arranged inside the cavity. Fixed plates 244 are arranged on the front and rear sides of the inner wall of the main tube 242. A fixed rod 245 is bolted between the opposite sides of the two fixed plates 244. A plurality of diverter plates 246 arranged at different angles are sleeved on the surface of the fixed rod 245. By setting the mixing mechanism 24, when the flushing liquid flows through the mixing mechanism 24, the heating wire 243 heats the flushing liquid to ensure that the temperature of the flushing liquid is appropriate and reduce stimulation to the tissue. At the same time, when the flushing liquid flows in the main tube 242, it is diverted and mixed by the diverter plate 246. After spiral flow, different components of the flushing liquid are fully mixed while being heated, ensuring that the flushing liquid reaches an ideal temperature and component uniformity, thereby providing a more suitable flushing liquid for surgery.

[0040] Among them, the top of the waste liquid collection box 27 and the liquid pump 26 are respectively connected with a collection pipe 12 and a supply pipe 13, and the collection pipe 12 and the supply pipe 13 are respectively connected with the flexible suction tube 362 and the flushing cavity. By setting the collection pipe 12 and the supply pipe 13, the effect of transporting flushing liquid and collecting waste liquid is achieved.

[0041] Working principle of this embodiment: before the operation begins, different types of flushing liquids are stored in the liquid storage unit 21 inside the main body shell 1. The liquid storage unit 21 can accommodate a variety of flushing liquids to meet the needs of different surgical situations. According to the specific needs of the operation, the corresponding flushing liquid is selected by controlling the multiple solenoid valves 22 in the flushing liquid supply and waste liquid collection structure 2. Different flushing liquids flow out of the liquid storage unit 21, gather in the manifold 23, and then enter the mixing mechanism 24. In the mixing mechanism 24, the flushing liquid enters the main pipe 242. The spiral device 241 in the cavity between the main pipe 242 and the fixed pipe 241 is used to control the flushing liquid supply and waste liquid collection structure 2. The heating wire 243 is arranged to heat the flushing liquid to a suitable temperature to reduce stimulation to the tissue. At the same time, the diverter plates 246 arranged at different angles divert and mix the flushing liquid. During the spiral flow, the different components of the flushing liquid are fully mixed to ensure that the temperature and component uniformity of the flushing liquid reach an ideal state. The flushing liquid that has been heated and mixed and optimized passes through the connecting pipe 25 and, under the action of the liquid pump 26, flows toward the holding tube 14, ready to enter the flushing structure 3 for flushing operation, and the waste liquid can enter the waste liquid collection box 27 through the flexible suction tube 362 through the negative pressure pump 28.
