Description

Technical Field

[0001] This invention relates to the field of medical equipment technology, specifically to a dynamic monitoring and heating system for water-medium endoscope water filter circulation. Background Technology

[0002] Currently, the rapidly expanding field of spinal endoscopic surgery uses water as a medium. This requires sterile saline or lactated Ringer's solution to create an optimal environment for the surgical area. Maintaining pressure and flow rate helps control local bleeding and ensures a clear field of vision. Compared to open surgery, spinal endoscopic surgery offers better protection of normal tissue structures, causes less overall disruption to the body, and allows for faster recovery. However, due to the more sophisticated tools used, the surgical efficiency is slightly lower than open surgery, resulting in a large volume of irrigation fluid consumption per procedure. This leads to a substantial consumption of saline solution. The saline solution after irrigation is managed as medical waste, which is charged by weight at 75 yuan / kg, or 75,000 yuan / ton. Given the large volume and quantity of irrigation waste, the resource consumption is significant. Therefore, a filtration system can be used to filter the saline solution for recycling, thereby reducing consumption and pollution, improving utilization, and lowering costs. This would be of great significance in reducing medical insurance expenditures and alleviating the burden on patients. Summary of the Invention

[0003] The purpose of this invention is to provide a dynamic monitoring and heating system for water filtration circulation in an aqueous endoscope to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A dynamic monitoring and heating system for water-based endoscope water filtration circulation includes a patient sterile area liquid barrier and collection bag, a peristaltic pump, a filtration system, and a saline bag connected in sequence. The delivery pipe connecting the peristaltic pump and the filtration system is heated by a temperature control box.

[0006] The patient sterile area liquid barrier and collection bag includes a liquid-fillable U-shaped dam-type barrier with a sterile film. Physiological saline is injected into the bag under pressure to deform it into a U-shape that surrounds the surgical area.

[0007] The filtration system includes a filter cartridge, one end of which is connected to the temperature-controlled heating pipeline via a delivery pipe, and the other end is provided with a detachable connector. A detachable filter screen is also provided inside the filter cartridge.

[0008] As a further aspect of the present invention: the filter cartridge is provided with a disassembly assembly that enables the connector to be sealed and connected to the filter cartridge. The disassembly assembly includes a locking structure and a docking structure. The docking structure is provided on the connector and the filter cartridge, and includes protrusions fixedly provided on the inner wall of the connector. At least two sets of protrusions are equidistantly provided along the circumferential direction of the connector. Each set of protrusions cooperates with an interlocking groove opened along the circumferential direction of the outer wall of the filter cartridge.

[0009] As a further embodiment of the present invention: the fitting groove includes a mating groove, an inclined groove and a locking groove, the inclined groove connects the mating groove and the locking groove, and the end of the mating groove away from the inclined groove is connected to the end face of the filter cylinder.

[0010] As a further embodiment of the present invention: the locking structure includes a lead screw rotatably mounted on the filter cylinder, a threaded sleeve threadedly connected to the lead screw, at least three sets of fixed sleeves along the circumferential direction of the threaded sleeve, the fixed sleeves being slidably connected to a guide rod fixedly disposed inside the filter cylinder, and a lifting component being fixedly disposed on the threaded sleeve.

[0011] As a further embodiment of the present invention: the lifting component includes a connecting rod fixedly connected to the threaded sleeve, and at least two sets of the connecting rod are equidistantly arranged along the circumferential direction of the threaded sleeve, and an abutment ring is fixedly provided at the end of the connecting rod away from the threaded sleeve.

[0012] As a further embodiment of the present invention: a support assembly is provided on the guide rod, the support assembly includes a deflection plate rotatably mounted on the guide rod, at least two sets of the deflection plate are provided along the axial direction of the guide rod, each set of the deflection plate is connected to a spring piece provided on the guide rod, and the two sets of the deflection plates are connected by a hinge rod.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] By setting up a patient sterile area liquid barrier and collection bag, peristaltic pump, filtration system and saline bag connected in sequence, the saline can be reused, reducing resource consumption;

[0015] By setting up a disassembly component and utilizing the cooperation between the docking structure and the locking structure, the connector and the filter cartridge can be quickly disassembled, so as to remove or replace the filter screen inside the filter cartridge and ensure the filtration effect of the filtration system.

[0016] Meanwhile, by utilizing the support components set on the guide rod, the deflection plate can be driven to rotate toward the connector as the abutment ring moves toward the connector. When the abutment ring abuts with the connector, the deflection plate is perpendicular to the guide rod, aligning the axis of the filter screen with the axis of the filter cylinder, preventing the filter screen from shifting and ensuring the filtration effect.

When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0028] Please see Figures 1-8 In this embodiment of the invention, a water-medium endoscope water filtration circulation dynamic monitoring and heating system includes a patient sterile area liquid barrier and collection bag, a peristaltic pump 102, a filtration system 104, and a saline bag 105 connected in sequence. The delivery pipe 4 connecting the peristaltic pump 102 and the filtration system 104 is heated by a temperature control box 103.

[0029] The patient sterile area liquid barrier and collection bag includes a liquid-fillable U-shaped dam-type barrier with a sterile film. Physiological saline is injected into the bag under pressure to deform it into a U-shape surrounding the surgical area 101.

[0030] The filtration system 104 includes a filter cylinder 1, one end of which is connected to the temperature-controlled heating pipeline via a delivery pipe 4, and the other end is provided with a detachable connector 2. A detachable filter screen 6 is provided inside the filter cylinder 1.

[0031] For details, please refer to Figure 1 , Figure 2 , Figure 3 The aforementioned connector 2 is connected to an outlet pipe 5, which is connected to a saline bag 105. The outlet pipe 5 can deliver filtered saline to the saline bag 105 for use in the U-shaped surrounding surgical area 101, thereby enabling the reuse of saline and reducing resource consumption.

[0032] The filter cartridge 1 is provided with a disassembly assembly that enables the connector 2 to be sealed and connected to the filter cartridge 1. The disassembly assembly includes a locking structure and a docking structure. The docking structure is provided on the connector 2 and the filter cartridge 1, and includes protrusions 12 fixedly provided on the inner wall of the connector 2. At least two sets of protrusions 12 are equidistantly provided along the circumferential direction of the connector 2. Each set of protrusions 12 cooperates with a fitting groove opened along the circumferential direction of the outer wall of the filter cartridge 1.

[0033] The fitting groove includes a docking groove 15, an inclined groove 16, and a locking groove 14. The inclined groove 16 connects the docking groove 15 and the locking groove 14, and the end of the docking groove 15 away from the inclined groove 16 is connected to the end face of the filter cylinder 1.

[0034] For details, please refer to Figure 2 , Figure 3 The aforementioned connector 2 is provided with an annular sealing ring 13, and the end of the mating groove 15 that communicates with the end face of the filter cylinder 1 is provided with an inclined guide surface. In use, by holding the connector 2 and the filter cylinder 1, the protrusion 12 can be quickly connected to the mating groove 15 under the action of the inclined guide surface. Then, push the connector 2 toward the filter cylinder 1, and the protrusion 12 moves along the mating groove 15 to the inclined groove 16. At this time, the end face of the filter cylinder 1 abuts against the sealing ring 13. Then continue to rotate the connector 2, and the protrusion 12 will move into the locking groove 14 under the guidance of the inclined groove 16, and squeeze the sealing ring 13 to deform it. At this time, the deformed sealing ring 13 will cause the protrusion 12 to be locked in the locking groove 14, so that the connector 2 is connected to the filter cylinder 1.

[0035] For further details, please refer to Figure 3 , Figure 5 , Figure 7 , Figure 8 The locking structure includes a lead screw 8 rotatably mounted on the filter cylinder 1, a threaded sleeve 9 threadedly connected to the lead screw 8, at least three sets of fixed sleeves 20 along the circumferential direction of the threaded sleeve 9, the fixed sleeves 20 being slidably connected to the guide rod 10 fixedly disposed in the filter cylinder 1, and a lifting component being fixedly disposed on the threaded sleeve 9.

[0036] For details, please refer to Figure 2 , Figure 3 , Figure 5 , Figure 7 , Figure 8A knob 3 is fixedly installed at one end of the lead screw 8 that protrudes from the filter cylinder 1. By rotating the knob 3, the threaded sleeve 9 can be driven to move along the axial direction of the lead screw 8. At the same time, under the cooperation of the fixed sleeve 20 and the guide rod 10, the threaded sleeve 9 driven by the lead screw 8 can only move up and down along the axial direction of the lead screw 8, thereby driving the lifting component connected to the lead screw 8 to move away from or closer to the knob 3.

[0037] The lifting component includes a connecting rod 11 fixedly connected to the threaded sleeve 9. At least two sets of the connecting rod 11 are equidistantly arranged along the circumferential direction of the threaded sleeve 9. An abutment ring 17 is fixedly provided at the end of the connecting rod 11 away from the threaded sleeve 9.

[0038] For details, please refer to Figure 3 , Figure 5 , Figure 7 In the initial state, the threaded sleeve 9 is close to the knob 3. As can be seen from the above, the stability of the connection between the connector 2 and the filter cylinder 1 is not enough, and it is easy to fall off. Therefore, the docking structure is used to connect the connector 2 and the filter cylinder 1. After the connector 2 and the filter cylinder 1 are connected, the knob 3 is turned to control the threaded sleeve 9 to move toward the connector 2 until the abutment ring 17 abuts with the connector 2. At this time, the squeezing force generated by the abutment ring 17 on the connector 2 can make the protrusion 12 lock in the locking groove 14, realizing the sealed connection between the connector 2 and the filter cylinder 1, and allowing normal operation. When it is necessary to clean or replace the filter screen 6 in the filter cylinder 1, the knob 3 is reversed to drive the threaded sleeve 9 toward the knob 3, so that the abutment ring 17 is separated from the connector 2. Then, the connector 2 is pulled outward by hand, which can realize the quick separation of the connector 2 and the filter cylinder 1, so as to carry out the cleaning work inside the filter cylinder 1.

[0039] In this embodiment of the invention, by setting up a disassembly component, the quick disassembly between the connector 2 and the filter cartridge 1 can be achieved by utilizing the cooperation between the docking structure and the locking structure, so as to facilitate the disassembly or replacement of the filter screen 6 inside the filter cartridge 1 and ensure the filtration effect of the filtration system 104.

[0040] For further details, please refer to [link / reference]. Figure 3 , Figure 5 , Figure 6 The guide rod 10 is provided with a support assembly, which includes a deflection plate 18 rotatably mounted on the guide rod 10. At least two sets of deflection plates 18 are provided along the axial direction of the guide rod 10. Each set of deflection plates 18 is connected to a spring piece 19 provided on the guide rod 10. The two sets of deflection plates 18 are connected by a hinge rod 7.

[0041] For details, please refer to Figure 6Under the connection of the fixed-length hinge rod 7, the two adjacent sets of deflection plates 18 and the hinge rod 7 form a parallelogram structure. In the initial state, that is, before the connector 2 is connected to the filter cylinder 1, the deflection plates 18 will deflect towards the knob 3 under the action of the spring piece 19. After the filter screen 6 in the filter cylinder 1 is replaced, the axis of the replaced filter screen may not be aligned with the axis of the filter cylinder 1. At this time, the offset filter screen 6 will reduce the contact area between the filtered saline entering from the delivery pipe 4 and the filter screen 6, thus reducing the filtration effect. Therefore, after the filter screen 6 is placed in the filter cylinder 1 and the connector 2 is connected to the filter cylinder 1, the screw 8 is rotated, and the descending threaded sleeve 9 moves axially along the guide rod 10. As the direction descends, the fixed sleeve 20 sliding on the guide rod 10 will contact the deflection plate 18 and push the deflection plate 18 towards the connector 2 until the abutment ring 17 abuts against the connector 2. Then, the fixed sleeve 20 pushes the deflection plate 18 perpendicular to the guide rod 10. Under the connection of the hinge rod 7, all the deflection plates 18 rotatably mounted on the guide rod 10 will move simultaneously, making the axis of the filter screen 6 coincide with the axis of the filter cylinder 1, so that the filter screen 6 will not be misaligned, ensuring the filtration effect. When the connector 2 is disassembled, the deflection plate 18 separated from the fixed sleeve 20 will return to its initial position under the action of the spring piece 19, so that the filter screen 6 can be replaced.

[0042] In this embodiment of the invention, by setting a support component, during the movement of the abutment ring 17 toward the connector 2, the deflection plate 18 is driven to rotate toward the connector 2. When the abutment ring 17 abuts against the connector 2, the deflection plate 18 is just perpendicular to the guide rod 10, so that the axis of the filter screen 6 coincides with the axis of the filter cylinder 1, so that the filter screen 6 will not be offset, thus ensuring the filtration effect.

[0043] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0044] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
