Description

Technical Field

[0001] This invention relates to the field of surgical instrument technology, specifically to a rotating microsurgical suction catheter and its performance testing method. Background Technology

[0002] Suction catheters are core auxiliary instruments in dental clinical treatments, such as tooth extraction, periodontal treatment, and fillings, which are performed under microsurgery. They are mainly used to suction blood, saliva, tissue debris, and secretions generated in the surgical area of ​​the oral cavity in real time. Their core function is to maintain a clear view of the surgical area, prevent blood and saliva from obscuring the surgical site, reduce contamination of the surgical area, provide stable suction support for the dentist's precise operation, and ensure the smooth progress of the surgery.

[0003] In actual operation, the catheter tip is generally a fixed integrated structure without rotational adjustment. The angle is fixed and the adjustment flexibility is poor. It is impossible to flexibly adjust the suction angle according to the location of the surgical area (such as the interproximal space of teeth, periodontal pockets, wisdom tooth blind pockets and other small and hidden areas), resulting in obvious suction dead zones and difficulty in completely suctioning blood and saliva from the surgical area. On the other hand, the suction channel of existing suction catheters is mostly a single aperture structure, and the smoothness of the channel wall is insufficient. During the suction process, tissue debris, blood clots and other debris in the surgical area are easy to adhere to the inner wall of the channel or block the suction port at the tip of the catheter. The unblocking operation is cumbersome and time-consuming, which not only seriously affects the efficiency of the surgical operation, but may also cause the suction function to fail due to blockage, which will lead to blurred vision and contamination of the surgical area and increase the surgical safety risks. Therefore, a rotating microsurgical treatment suction catheter and performance testing method are proposed to solve the above problems. Summary of the Invention

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a rotating microsurgical suction catheter and its performance testing method. It boasts advantages such as flexible catheter tip rotation, adaptability to narrow and concealed dental surgical areas, and elimination of suction blind spots. This solves the problems of commonly used fixed, integrated catheter tips lacking rotatable adjustment capabilities, having fixed angles with poor adjustment flexibility, and being unable to flexibly adjust the suction angle according to the location of the surgical area (such as interproximal spaces, periodontal pockets, and wisdom tooth blind pockets), resulting in significant suction blind spots and difficulty in thoroughly suctioning blood and saliva from the surgical area. Furthermore, existing suction catheters often have a single-aperture suction channel with insufficient smoothness of the inner wall. During suction, tissue debris, blood clots, and other impurities in the surgical area easily adhere to the inner wall of the channel or block the suction port at the catheter tip. Unblocking these obstructions is cumbersome and time-consuming, severely impacting surgical efficiency and potentially causing suction failure due to blockage, leading to blurred or contaminated surgical views and increased surgical safety risks.

[0005] (II) Technical Solution The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A rotating microsurgical treatment suction catheter includes a tube body, one end of which is detachably connected to a replaceable suction head communicating with the tube body, the replaceable suction head being rotatable and foldable, a clamping tube fixedly connected to the outside of the tube body, a clamping assembly for positioning and assembling the replaceable suction head fixedly connected to the outside of the clamping tube, a dredging assembly fixedly connected to the outside of the tube body, and a negative pressure tube connected to the end of the tube body away from the replaceable suction head; The replaceable suction head includes a connecting tube, rubber balls, an adsorption tube, adsorption holes, and a connecting sleeve. The connecting sleeve is rotatably fitted into the inner side of the tube body and is sealed and connected to the tube body. There are multiple rubber balls, and adjacent rubber balls are connected to each other through the connecting tube. The rubber ball closest to the tube body is connected to the connecting sleeve, the rubber ball closest to the tube body is connected to the connecting sleeve, and the rubber ball furthest from the tube body is connected to the adsorption tube. Multiple evenly distributed adsorption holes are opened on the outer side of the adsorption tube. The negative pressure tube, tube body, connecting sleeve, rubber ball, connecting tube, adsorption tube and adsorption hole are connected in sequence to form a continuous negative pressure guiding channel.

[0006] The beneficial effects of this invention are: 1) This rotating microsurgical treatment suction catheter and performance testing method have the advantages of flexible catheter tip rotation, adaptability to narrow and hidden dental surgical areas, and elimination of suction dead angles.

[0007] 2) This rotating microsurgical treatment suction catheter and performance testing method have the advantages of excellent anti-blockage effect of suction channel, rapid unblocking, and avoiding blockage affecting surgical efficiency.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, an anti-slip sleeve is fixedly fitted on the outer side of the middle end of the tube body, and the outer side of the anti-slip sleeve is provided with anti-slip texture. An indicator light is fixedly connected to the outer side of the tube body.

[0010] Furthermore, the snap-fit ​​assembly includes a side end limiting component, a snap-fit ​​plate, a snap-fit ​​rod, and a rubber pad. The side end limiting component is fixedly connected to the outside of the tube body. The inside of the snap-fit ​​plate is slidably connected to the outside of the side end limiting component. The snap-fit ​​rod is fixedly connected to the bottom end of the snap-fit ​​plate and extends through the connecting sleeve to the inside of the snap-fit ​​tube. The rubber pad is fixedly wrapped around the outside of the snap-fit ​​rod.

[0011] Furthermore, the side-end limiting assembly includes a side-end limiting box and a limiting rod. The side-end limiting box is fixedly connected to the outside of the clamping tube, and the limiting rod is fixedly connected to the inside of the side-end limiting box, with its outside slidably connected to the inside of the clamping plate. A pull handle is fixedly connected to the top of the clamping plate.

[0012] Furthermore, the unblocking component includes an unblocking pipe, a pulse pipe, and a negative pressure sensor. One end of the unblocking pipe is connected to the pipe body, and the other end of the unblocking pipe is connected to the pulse pipe. The negative pressure sensor is fixedly connected to the inside of the pipe body.

[0013] Furthermore, the negative pressure sensor is electrically connected to the indicator light, and a one-way valve is fixedly connected to the inner side of the unblocking pipe. The one-way valve is directed to flow from the pulse tube to the unblocking pipe.

[0014] Furthermore, the inner side of the negative pressure guiding channel is coated with a superhydrophobic coating.

[0015] A performance testing method for a rotating microsurgical suction catheter includes the following steps: S1: Position and fix the tube body of the rotating microsurgical treatment suction catheter to the test fixture to keep the tube body in a stable position; S2: Apply a force to the replaceable suction head at the front end of the tube body, causing the replaceable suction head to twist relative to the tube body at a set angle; S3: Continuously observe the structural deformation state of the replaceable suction head within a set time period to complete the structural stability test of the replaceable suction head after rotation; S4: Use a sealing component to seal the suction hole of the suction tube on the replaceable suction head to simulate the blockage of the negative pressure guide channel during microsurgery. S5: Open the negative pressure tube to establish a negative pressure adsorption state. The negative pressure sensor inside the tube collects the negative pressure abnormal signal under the blockage state and controls the indicator light to emit a red warning signal. S6: Upon receiving a red warning signal, close the negative pressure pipe to stop the negative pressure supply, and simultaneously activate the pulse pipe of the unblocking component to output pulse unblocking medium; S7: The pulse unblocking medium flows unidirectionally into the negative pressure guide channel inside the unblocking pipe to unblock the blockage location with pulses, testing the negative pressure rapid unblocking effect of the unblocking component.

[0016] Furthermore, in step S7, the pulse unblocking medium flows into the negative pressure guiding channel through the one-way valve inside the unblocking pipe. After unblocking is completed, the negative pressure recovery value is detected by the negative pressure sensor, and the unblocking effect of the unblocking component is determined based on the negative pressure recovery value.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1, by Figure 1-5 A rotating microsurgical suction catheter is provided. The invention includes a tube body 1, one end of which is detachably connected to a replaceable suction head 2 that communicates with the tube body 1. The replaceable suction head 2 is rotatable and foldable. A retaining tube 3 is fixedly connected to the outside of the tube body 1. A retaining assembly 4 for positioning and assembling the replaceable suction head 2 is fixedly connected to the outside of the retaining tube 3. A drainage assembly 5 is fixedly connected to the outside of the tube body 1. A negative pressure tube 6 is connected to the end of the tube body 1 away from the replaceable suction head 2. The replaceable suction head 2 includes a connecting tube 21, a rubber ball 22, an adsorption tube 23, an adsorption hole 24, and a connecting sleeve 25. The connecting sleeve 25 is rotatably fitted into the inner side of the tube body 1 and is sealed and connected to the tube body 1. There are multiple rubber balls 22. Adjacent rubber balls 22 are connected to each other through the connecting tube 21. The rubber ball 22 closest to the end of the tube body 1 is connected to the connecting sleeve 25. The rubber ball 22 furthest from the tube body 1 is connected to the adsorption tube 23. Multiple evenly distributed adsorption holes 24 are opened on the outer side of the adsorption tube 23. The negative pressure tube 6, tube body 1, connecting sleeve 25, rubber ball 22, connecting tube 21, adsorption tube 23 and adsorption hole 24 are connected in sequence to form a continuous negative pressure guiding channel.

[0021] This application realizes the detachable and rotatable foldable design of the replaceable suction head 2 of the suction catheter. The snap-fit ​​component 4 ensures the stable assembly and positioning of the replaceable suction head 2 and the tube body 1. The unblocking component 5 ensures the unobstructed negative pressure guide channel. The negative pressure tube 6, together with the tube body 1, connecting sleeve 25, rubber ball 22, connecting tube 21, suction tube 23 and suction hole 24, forms a continuous negative pressure guide channel that can stably realize microsurgical suction operation.

[0022] In this embodiment, an anti-slip sleeve 7 with anti-slip texture can be fixedly fitted on the outer side of the middle end of the tube body 1, and an indicator light 8 can be fixedly installed on the outer side of the tube body 1. The indicator light 8 can emit corresponding prompt signals according to the operating status of the equipment, which can intuitively reflect the operating status of the equipment and facilitate the control of microsurgical operations.

[0023] In this embodiment, the snap-fit ​​assembly 4 includes a side-end limiting assembly 41, a snap-fit ​​plate 42, a snap-fit ​​rod 43, and a rubber pad 44. The side-end limiting assembly 41 is fixed to the outside of the tube body 1 to form a limiting base. The snap-fit ​​plate 42 slides along the outside of the side-end limiting assembly 41. The snap-fit ​​rod 43 slides with the snap-fit ​​plate 42 and extends through the connecting sleeve 25 into the inside of the snap-fit ​​tube 3 to achieve snap-fit ​​positioning of the connecting sleeve 25. The rubber pad 44 wrapped around the outside of the snap-fit ​​rod 43 improves the sealing and stability of the snap-fit ​​part.

[0024] The side-end limiting assembly 41 includes a side-end limiting box 401 and a limiting rod 402. The side-end limiting box 401 is fixed on the outside of the locking tube 3. The limiting rod 402 on the inside provides a sliding guide for the locking plate 42. The pull handle at the top of the locking plate 42 can drive the locking plate 42 to slide along the limiting rod 402, thereby driving the locking rod 43 to complete the locking or unlocking action.

[0025] The snap-fit ​​assembly 4, through the snap-fit ​​rod 43 and the snap-fit ​​tube 3, enables the quick positioning and assembly of the connecting sleeve 25 of the replaceable suction head 2. The rubber pad 44 ensures the sealing and stability of the snap-fit ​​part, improves the reliability of the connection between the replaceable suction head 2 and the tube body 1, and facilitates the disassembly and replacement of the replaceable suction head 2.

[0026] In this embodiment, the unblocking component 5 includes an unblocking pipe 51, a pulse pipe 52, and a negative pressure sensor 53. The two ends of the unblocking pipe 51 are connected to the pipe body 1 and the pulse pipe 52, respectively. The negative pressure sensor 53 inside the pipe body 1 detects the negative pressure state in the negative pressure guide channel in real time. The pulse pipe 52 can deliver unblocking medium into the pipe body 1 through the unblocking pipe 51 to achieve unblocking of the channel. At the same time, the negative pressure sensor 53 transmits the detected negative pressure signal to the indicator light 8. When the negative pressure is abnormal, the indicator light 8 is controlled to issue a warning. The one-way valve 9 in the unblocking pipe 51 only allows the medium in the pulse pipe 52 to flow to the unblocking pipe 51, preventing the medium in the channel from flowing back.

[0027] The unblocking component 5 monitors the negative pressure status inside the tube body 1 through the negative pressure sensor 53, and works with the unblocking tube 51 and the pulse tube 52 to unblock the negative pressure guiding channel, so as to avoid the channel blockage affecting the use of surgery.

[0028] In this embodiment, a superhydrophobic coating is applied to the inner wall of the negative pressure guiding channel formed by the negative pressure tube 6, tube body 1, connecting sleeve 25, rubber ball 22, connecting tube 21, adsorption tube 23 and adsorption hole 24 to reduce the adhesion of substances.

[0029] Example 2, by Figure 6 A performance testing method for a rotating microsurgical suction catheter is provided, comprising the following steps: S1: Position and fix the tube body 1 of the rotating microsurgical treatment suction catheter to the test fixture to keep the tube body 1 in a stable position. S2: Apply force to the replaceable suction head 2 at the front end of the tube body 1, so that the replaceable suction head 2 completes a twisting action at a set angle relative to the tube body 1. S3: Continuously observe the structural deformation state of the replaceable nozzle 2 within the set time period to complete the structural stability test of the replaceable nozzle 2 after rotation. S4: The suction hole 24 of the suction tube 23 on the replaceable suction head 2 is sealed with a sealing component to simulate the blockage of the negative pressure guide channel during microsurgery. S5: Open the negative pressure tube 6 to establish a negative pressure adsorption state. The negative pressure sensor 53 inside the tube body 1 collects the negative pressure abnormal signal under the blockage state and controls the indicator light 8 to emit a red warning signal. S6: Upon receiving a red warning signal, close the negative pressure pipe 6 to stop the negative pressure supply, and simultaneously activate the pulse pipe 52 of the unblocking component 5 to output pulse unblocking medium; S7: The pulse unblocking medium flows unidirectionally into the negative pressure guide channel inside the pipe body 1 through the unblocking pipe 51 to unblock the blockage location with pulse, and tests the negative pressure rapid unblocking effect of the unblocking component 5.

[0030] This testing method can simulate microsurgical conditions and sequentially test the rotational stability of the replaceable suction tip 2 and the unblocking effect of the unblocking component 5, comprehensively verifying the performance of the suction catheter body 1, the replaceable suction tip 2 and the supporting components.

[0031] In this embodiment, in step S7, the pulse unblocking medium flows into the negative pressure guiding channel through the one-way valve 9 inside the unblocking pipe 51. After unblocking is completed, the negative pressure recovery value is detected by the negative pressure sensor 53, and the unblocking effect of the unblocking component 5 is determined based on the negative pressure recovery value.
