Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a peristaltic pump pulsed water supply device for an ultrasonic bone cutter machine. Background Art

[0002] A dental bone cutter machine generally refers to an ultrasonic bone cutter, which is a medical device that uses the principle of high-intensity focused ultrasound for bone surgery. Ultrasonic bone cutters are widely used in dental surgeries, including but not limited to dental implant surgeries, tooth extractions, periodontal disease treatments, root canal treatments, etc. Its advantage lies in being able to precisely cut bone tissue while reducing damage to surrounding soft tissues, improving the safety and precision of surgeries. Generally, an ultrasonic bone cutter machine consists of a main unit, a handpiece, a working tip (tool bit), a flushing tube, and a foot pedal, and it is a Class III medical device.

[0003] During surgery, the temperature of the tool bit of the ultrasonic bone cutter is maintained below 38°C, generally achieved by synchronously spraying water. Meanwhile, if necessary, cleaning water is also sprayed out from the flushing tube to flush the oral cavity, timely removing the sticky water, blood water, or tooth tissues in the oral cavity. Currently, the water supply for ultrasonic bone cutter machines is divided into two categories: tap water and sterile water. Among them, for sterile water, due to the need for a closed water supply pipeline, a peristaltic pump is required to supply water by rolling extrusion.

[0004] The advantage of a peristaltic pump is that it can be well isolated from the pipeline without contaminating the pipeline. However, in terms of precise water supply, especially for low-flow water supply, the peristaltic pump often has a low rotational speed and the output water becomes discontinuous, which has a great impact on the cooling performance of the working tip (tool bit) and cannot meet the clinical requirements. Summary of the Utility Model

[0005] In order to overcome at least one of the above-mentioned defects of the prior art, the utility model provides a peristaltic pump pulsed water supply device for an ultrasonic bone cutter machine. By adding a buffer mechanism at the rear of the peristaltic pump, the water flow transported by the peristaltic pump is buffered and temporarily stored, and then continuously transported to the water-using position.

[0006] The technical solution adopted by the utility model to solve its problems is as follows:

[0007] A peristaltic pump pulsed water supply device for an ultrasonic bone cutter machine includes a first water supply pipeline and a peristaltic pump. The first water supply pipeline includes an input end and an output end. The peristaltic pump is installed on the first water supply pipeline and transports water flow from the input end to the output end. A buffer mechanism is also provided on the first water supply pipeline. The buffer mechanism receives and temporarily stores the water flow transported by the peristaltic pump from the input end, and the water flow is continuously transported to the output end after passing through the buffer mechanism.

[0008] Further: The buffer mechanism includes a receiving cavity which communicates with the first water supply pipe. The water flow at the input end is transported by the peristaltic pump to the receiving cavity, and after being temporarily stored in the receiving cavity, it is continuously transported to the output end.

[0009] Further: The buffer mechanism includes a buffer bag which forms the receiving cavity and communicates with the first water supply pipe.

[0010] Further: The buffer bag and the first water supply pipe are integrally formed.

[0011] Further: Along the radial direction of the first water supply pipe, the inner diameter of the receiving cavity is larger than that of the first water supply pipe.

[0012] Further: The capacity of the receiving cavity is 1 - 10 ml.

[0013] Further, the peristaltic pump pulse water supply device of the ultrasonic osteotome machine further includes a first water stop valve which is arranged on the first water supply pipe and behind the buffer mechanism.

[0014] Further, the peristaltic pump pulse water supply device of the ultrasonic osteotome machine further includes a second water supply pipe which is connected to the water outlet of the peristaltic pump and arranged side by side with the buffer mechanism; a second water stop valve is also arranged on the second water supply pipe.

[0015] Further: A control mechanism is connected to the peristaltic pump. According to the flow rate at the input end, when the water supply of the peristaltic pump ends, the control mechanism controls the peristaltic pump to reverse or directly stop.

[0016] Further: The control mechanism includes a PLC controller and a flow sensor. The PLC controller controls the peristaltic pump to reverse according to the flow rate at the input end sensed by the flow sensor and greater than the set value, so as to eliminate the water flow remaining in the buffer mechanism.

[0017] In summary, the peristaltic pump pulse water supply device of the ultrasonic osteotome machine provided by the present utility model has the following technical effects:

[0018] 1. A buffer mechanism is arranged behind the peristaltic pump on the first water supply pipe. The buffer mechanism receives the water flow transported by the peristaltic pump from the input end, and the water flow is continuously transported to the output end after passing through the buffer mechanism, realizing that the first water supply pipe can also achieve continuous water supply during low-flow water supply, meeting the water use requirements of the water use position.

[0019] 2. A first water stop valve is installed on the first water supply pipe and behind the peristaltic pump. In the case of large water supply flow, when the water use stops, the first water stop valve is timely closed to avoid water cut-off delay.

[0020] 3. Connect a second water supply pipe connected to the buffer mechanism to the peristaltic pump. Use the first water supply pipe for water supply. In the case of large-flow water supply, use the second water supply pipe for water supply. In the case of small-flow water supply, the problem of discontinuous small-flow water supply is well solved, and at the same time, the problem of water shut-off delay that occurs during large-flow water supply is solved.

[0021] 4. A control mechanism is connected to the peristaltic pump. According to the flow rate at the input end, when the water supply of the peristaltic pump ends, the control mechanism controls the peristaltic pump to reverse or directly stop. At this time, there is no need to set up a second water supply pipe, and a first water stop valve can also not be set on the first water supply pipe, making the structure of the water supply device simpler. At the same time, the problem of discontinuous small-flow water supply is solved, and the problem of instantaneous burst water impact that occurs when starting water supply again after large-flow water supply is also solved.

[0030] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0031] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model in this article are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

[0033] As Figure 1 shown, it is a schematic structural diagram of an embodiment of a water supply device for an ultrasonic bone scalpel machine in the prior art, mainly including a first water supply pipe 1 and a peristaltic pump 2 installed on the first water supply pipe. The peristaltic pump conveys the water flow in the first water supply pipe 1, and the water flow flows from the input end 11 to the output end 12, and the output end 12 is located at the water usage position. During the conveying process, the peristaltic pump does not directly contact the water flow, and the water flow is sealed in the first water supply pipe, meeting the water usage hygiene standard.

[0034] In the water supply device for an ultrasonic bone scalpel machine in the prior art, due to the working principle and working state of the peristaltic pump, the water flow conveyed in the first water supply pipe 1 is pulsed and cannot be continuously output. Especially when the water flow at the input end is small or the required water flow for water usage is small, a continuous water flow cannot be obtained at the output end, affecting the cooling effect of the tip of the bone scalpel or the flushing effect in the oral cavity and unable to meet the treatment requirements.

[0035] To solve the above problems, a pulsed water supply device for the peristaltic pump 2 of an ultrasonic bone scalpel machine of the technical solution of the present utility model is proposed.

[0036] A pulsed water supply device for the peristaltic pump 2 of an ultrasonic bone scalpel machine includes a first water supply pipe 1 and a peristaltic pump 2. The first water supply pipe 1 includes an input end and an output end. The peristaltic pump 2 is installed on the first water supply pipe 1 and conveys the water flow from the input end to the output end. A buffer mechanism 3 is additionally provided on the first water supply pipe 1. The buffer mechanism 3 receives and temporarily stores the water flow conveyed by the peristaltic pump 2 from the input end 11, and the water flow is continuously conveyed to the output end 12 after passing through the buffer mechanism 3.

[0037] Based on the above technical solution, the buffer mechanism is used to buffer and temporarily store the water flow conveyed by the peristaltic pump, and then the water temporarily stored in the buffer mechanism is conveyed to the output end, so that a continuous water flow is obtained at the water-using position, meeting the requirements of oral treatment water, especially for the continuous cooling effect on the tip of the osteotome machine.

[0038] Based on the above technical solution, as Figure 2 shown, it is a schematic structural diagram of Embodiment 1 of the pulsed water supply device of the peristaltic pump 2 of the ultrasonic osteotome machine. When the water supply device of this embodiment works, first start the peristaltic pump. The peristaltic pump conveys the water flow in the first water supply pipeline. When the water flow reaches the position of the buffer mechanism 3, the buffer mechanism temporarily stores the water flow, and then it flows to the output end. Especially when the water supply flow is small, the water flow conveyed by the peristaltic pump enters the buffer mechanism, is buffered, received and temporarily stored by the buffer mechanism. When the water pressure or water flow in the buffer mechanism is sufficient, it is then conveyed to the output end. The water flow is temporarily stored in the buffer mechanism. At this time, the continuous water flow section starts from the position of the buffer mechanism and is continuously conveyed to the output end. That is, in this solution, by adding a buffer mechanism, the pulsed water supply device of the peristaltic pump 2 of the ultrasonic osteotome machine can supply water continuously to the water-using position.

[0039] Based on the above technical solution, the buffer mechanism 3 includes a receiving cavity. The receiving cavity is communicated with the first water supply pipeline 1. The water flow at the input end is conveyed by the peristaltic pump 2 into the receiving cavity, and after being temporarily stored in the receiving cavity, it is continuously conveyed to the output end. The receiving cavity is communicated with the first water supply pipeline, and is used to receive the water flow conveyed by the peristaltic pump, so that the water flow is temporarily stored in the receiving cavity. After the water flow rate or water pressure in the receiving cavity reaches a certain value, the water flow in the receiving cavity will be continuously conveyed to the output end.

[0040] To simplify the structure of the buffer mechanism, the buffer mechanism 3 includes a buffer bag. The buffer bag forms the receiving cavity, and the buffer bag is communicated with the first water supply pipeline 1. The buffer mechanism 3 only has a buffer bag, with a simple structure and low cost.

[0041] To further simplify the structure of the buffer mechanism, the buffer bag and the first water supply pipeline 1 are integrally formed. Generally, the first water supply pipeline is formed of rubber or latex or silica gel or plastic. By integrally forming the buffer bag and the first water supply pipeline, the forming process is simple, the manufacturing cost is low, and it is convenient for the reliable connection between the buffer bag and the first water supply pipeline.

[0042] In order to achieve the functions of buffering and water storage and at the same time simplify the structure of the receiving cavity, the receiving cavity is generally designed as a cylindrical cavity, and along the radial direction of the first water supply pipeline 1, the inner diameter of the receiving cavity is larger than the inner diameter of the first water supply pipeline 1, which can retain more water flow, provide greater water pressure, and realize the continuous conveyance of the water flow.

[0043] In this technical solution, in order to obtain a sufficient large water pressure, the capacity of the receiving cavity is 1 - 10 ml.

[0044] Based on the above technical solution, a buffer mechanism is added to the first water supply pipe for receiving and temporarily storing the water flow conveyed by the peristaltic pump 2 from the input end 11. After passing through the buffer mechanism 3, the water flow is continuously conveyed to the output end 12. Especially when the water flow in the first water supply pipe is small, a water flow with a certain flow rate can be obtained at the output end. However, if the water flow conveyed in the first water supply pipe is large, at this time, more water will remain in the buffer mechanism. When the peristaltic pump is turned off, there will still be more water remaining in the buffer mechanism. At this time, the water in the buffer mechanism will continue to be quickly conveyed to the output end, that is, there will be a problem of water cut-off delay at the output end.

[0045] To solve the problem of water cut-off delay at the output end in the case of large-flow water supply, in this solution, based on Embodiment 1, a first water stop valve 4 is added, as Figure 3 shown in Embodiment 2. The first water stop valve 4 is arranged on the first water supply pipe 1 and is located behind the buffer mechanism 3. After setting the first water stop valve 4, when the peristaltic pump is turned off and stops conveying, the first water stop valve 4 is closed at the same time, so that the water remaining in the buffer mechanism will not continue to be conveyed to the conveying end, solving the problem of water cut-off delay at the output end in the case of large-flow water supply.

[0046] Based on the above technical solution, the first water stop valve 4 can be an electromagnetic valve, which is controlled to open and close through an electric signal, and the control is simple and convenient. Of course, the first water stop valve 4 can also be a manual valve, which is closed manually.

[0047] In the above solution, adding the first water stop valve 4 behind the buffer mechanism well solves the problem of water cut-off delay at the output end when supplying water with a large flow rate. However, when the handpiece of the ultrasonic bone knife machine is started again, the peristaltic pump and the first water stop valve 4 are started synchronously. At this time, a large amount of water remaining in the buffer mechanism will be immediately conveyed to the conveying end. At the moment when the first water stop valve 4 is opened, the water in the buffer mechanism is immediately conveyed to the conveying end, and the water in the buffer mechanism bursts instantaneously and forms a high-pressure water flow, which impacts the oral cavity. On the one hand, it may cause discomfort to the patient or affect the doctor's treatment operation. Especially when a smaller water flow is required at this time, this solution cannot fully meet or meet all the water use requirements.

[0048] To solve the above situation where a large amount of water remains in the buffer mechanism after the peristaltic pump is turned off when supplying water with a large flow rate, the solutions of Embodiment 3, Embodiment 4, and Embodiment 5 are proposed below.

[0049] As Figure 4 , which is a schematic structural diagram of Embodiment 3, an ultrasonic bone knife machine peristaltic pump 2 pulse water supply device. Based on Embodiment 2, a second water supply pipe 5 is added. The second water supply pipe 5 is connected to the water outlet of the peristaltic pump 2 and is arranged parallel to the buffer mechanism 3. A second water stop valve 6 is also arranged on the second water supply pipe 5.

[0050] Based on the solution of Embodiment 3 above, when supplying water at low flow rate, water is supplied through the first water supply pipe and the buffer mechanism. When supplying water at high flow rate, water is supplied through the second water supply pipe. When the first water supply pipe supplies water, the first water stop valve opens, and at the same time, the second water stop valve closes. When the second water supply pipe supplies water, the second water stop valve opens, and at the same time, the first water stop valve closes.

[0051] Based on the solution of Embodiment 3 above, when the first water supply pipe supplies water at low flow rate, the low-flow pulsed water conveyed by the peristaltic pump enters the buffer mechanism and is temporarily stored by the buffer mechanism, and then the buffer mechanism continuously conveys it to the output end. When the first water supply pipe stops supplying water, the peristaltic pump closes. At this time, because the water supply flow rate is small, there is less water stored in the buffer mechanism. When the second water supply pipe supplies water at high flow rate, the high-flow pulsed water conveyed by the peristaltic pump directly enters the second water supply pipe for water supply. Because the conveyed water flow rate is large, even if the water conveyed by the peristaltic pump is pulsed, continuous water output will occur at the output end. At this time, when the second water supply pipe stops supplying water, the peristaltic pump closes, and there is basically no water left in the second water supply pipe. At this time, because the first water stop valve is closed, when the second water supply pipe supplies water, less water enters the buffer mechanism. Therefore, there is no problem that a large amount of water remains in the buffer mechanism when the second water supply pipe supplies water, and it also solves the situation that a shock water flow bursts out in the buffer mechanism when small-flow water supply is carried out again after large-flow water supply.

[0052] Based on Embodiment 3 above, in order to prevent water from entering and remaining in the buffer mechanism when supplying water at high flow rate, a three-way valve can be used to connect at the connection between the second water supply pipe and the first water supply pipe or at the connection between the second water supply pipe and the water outlet of the peristaltic pump, ensuring that the water output by the peristaltic pump only enters the buffer mechanism or only enters the second water supply pipe. This can further ensure the problem that water enters the buffer mechanism for temporary storage when supplying water at high flow rate, and avoid the situation that a shock water flow bursts out in the buffer mechanism when small-flow water supply is carried out again after large-flow water supply.

[0053] As Figure 5 shown in [figure number], it is a schematic structural diagram of Embodiment 4. The peristaltic pump 2 of the ultrasonic bone scalpel machine is a pulsed water supply device, and a control mechanism is added on the basis of Embodiment 2. The control mechanism is connected to the peristaltic pump 2. According to the flow rate of the input end, when the water supply of the peristaltic pump 2 ends, the control mechanism controls the peristaltic pump 2 to reverse or directly stop.

[0054] Based on the above-mentioned Embodiment 4, the control mechanism controls the forward rotation, reverse rotation or stop of the peristaltic pump. During normal water supply, the peristaltic pump rotates forward to deliver water flow to the output end. When the water supply ends, the control mechanism controls the peristaltic pump 2 to reverse or directly stop. If it was just a low-flow water supply, at the end of the water supply, the control mechanism controls the peristaltic pump 2 to directly stop. If it was just a high-flow water supply, the control mechanism controls the peristaltic pump 2 to reverse. When stopping the water supply in the case of high-flow water supply, when the peristaltic pump stops supplying water, the first water stop valve closes, and there will be more water flow retained in the buffer mechanism. At this time, the peristaltic pump reverses, and the more water flow in the buffer mechanism is conveyed in the reverse direction to the input end, thus realizing the pressure relief of the water flow in the buffer mechanism. After the peristaltic pump reverses, the water flow in the buffer mechanism is pressure-relieved. When starting the peristaltic pump to supply water again, even if a low-flow water supply is required at this time, there will be no sudden large-flow water impact problem at the output end.

[0055] Based on the above-mentioned Embodiment 4, the control mechanism includes a PLC controller and a flow sensor 7. The PLC controller controls the peristaltic pump 2 to reverse according to the flow rate at the input end sensed by the flow sensor 7 that is greater than the set value, so as to eliminate the water flow retained in the buffer mechanism 3. The so-called "set value" is the value specified to distinguish low-flow water flow and high-flow water flow, and the "set value" is input into the PLC controller in advance. The PLC controller compares the real-time value of the water flow rate at the input end sensed by the flow sensor with the set value. If the real-time value is greater than the set value, at the end of the water supply, it controls the peristaltic pump to reverse. If the real-time value is not greater than the set value, at the end of the water supply, it controls the peristaltic pump to directly stop.

[0056] Because the capacity of the accommodation cavity in the buffer mechanism is limited, the reverse rotation time of the peristaltic pump is very short, generally within a few seconds or more than ten seconds.

[0057] The flow sensor 7 can adopt a commonly used flow sensor in the prior art, such as an ultrasonic flow sensor, an electromagnetic flow sensor, etc.

[0058] Such as Figure 6 , which is a schematic structural diagram of Embodiment 5, a pulsed water supply device for the peristaltic pump 2 of an ultrasonic bone scalpel machine. A control mechanism is added on the basis of Embodiment 1, that is, the first water stop valve is cancelled on the basis of Embodiment 4. In the case of low-flow water supply, at the end of the water supply, the control mechanism controls the peristaltic pump 2 to directly stop. At this time, very little liquid remains in the buffer mechanism. When the peristaltic pump stops supplying water, there is basically no water flow out at the output end immediately, that is, there is basically no delay in water cut-off at the input end at this time. In the case of high-flow water supply, when the peristaltic pump stops supplying water, the control mechanism controls the peristaltic pump 2 to reverse to relieve the pressure of the more water flow in the buffer mechanism. At this time, there is basically no water flow retained in the buffer mechanism, and the first water stop valve at the rear of the buffer mechanism can be removed at this time.

[0059] The technical means disclosed by the solution of the present utility model are not limited to those disclosed in the above embodiments, but also include technical solutions formed by any combination of the above technical features. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications are also regarded as the protection scope of the present utility model.
