Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a warm water flushing system for acoustic neuroma. Background Art

[0002] Acoustic neuroma refers to a tumor that originates from the acoustic nerve sheath. The exact name is acoustic neuroma. It is one of the common intracranial tumors, accounting for 7% to 12% of intracranial tumors and 80% to 95% of cerebellopontine angle tumors. It is more common in adults, with a high incidence age of 30 to 50 years old. It is less common in those under 20 years old. Single acoustic neuroma in children is very rare. There is no obvious gender difference in acoustic neuroma. The incidence of left and right is similar, and bilaterality is occasionally seen.

[0003] Surgery is the most common treatment method. Radiotherapy is also one of the methods for treating acoustic neuroma. It can be performed alone or as an adjuvant treatment for surgery, mainly as an adjuvant treatment after surgery. Flushing and suction are required during the operation to keep the nerves full. Flushing can remove cell debris, surface microorganisms, residual local drugs and dressings on the surgical wound, thereby keeping the surgical wound clean. This cleaning effect helps doctors observe the surgical situation, reduce the occurrence of complications, help reduce the risk of infection, and promote wound healing.

[0004] However, existing flushing devices used during surgery generally have the following two problems: (1) The water pressure of flushing is difficult to control flexibly. If the pressure is too high or too low, the water flow rate will be too much or too little, making it difficult to control accurately; (2) The shape of the water flow is difficult to control. Splashing and streamline cannot be accurately controlled.

[0005] The invention patent with publication number CN 114098849 B discloses a surgical intraoperative flushing device, including a water reservoir, a delivery pipeline, a flushing gun body, a flushing gun head and a flushing controller. It is an integrated structure that can form a rich control process to adapt to the flow and water pressure in the flushing scene, does not occupy the surgical field of view, and can adapt to flushing applications in different scenarios. However, when in use, the flushing device relies on the flushing controller to control the water pressure and water flow rate. It is necessary to operate the flushing controller separately when flushing the handheld flushing wall, which increases the complexity of the operation; in addition, after the water supply is stopped, the remaining water in the entire flushing device pipeline will be delayed in flowing out, resulting in a large loss of water flow and internal drugs. Summary of the invention

[0006] In view of the above-mentioned problems, the present invention aims to provide a warm water flushing system for acoustic neuroma, which can adjust the water pressure and water flow pattern through the flushing system itself to prevent splashing; and can control the water flow to stop flowing immediately after the flushing operation is completed, thereby saving the loss of water flow and the medicine therein.

[0007] In order to achieve the above object, the technical solution adopted by the present invention is as follows: A warm water flushing system for acoustic neuroma includes a flushing pipe, the front end of which is connected to a first control component for adjusting water pressure and flow, the front end of the first control component is connected to a pressure-stabilizing pipe, and the front end of the pressure-stabilizing pipe is connected to a second control component for adjusting the water flow pattern.

[0008] Furthermore, the first control component includes a regulating valve for controlling the flow of water, and the front end of the regulating valve is provided with a connecting pipe that is interconnected, and the connecting pipe is sequentially provided with a first one-way diaphragm, a hemispherical pressure regulating disk, an elastic column and a base, the first one-way diaphragm and the base are both connected to the connecting pipe, and the two ends of the elastic column are respectively connected to the hemispherical pressure regulating disk and the base.

[0009] Furthermore, the hemispherical pressure regulating disc is a hollow hemispherical structure, and its outer diameter is smaller than the inner diameter of the connecting pipe.

[0010] Furthermore, a gap is provided between the base and the inner wall of the connecting pipe.

[0011] Furthermore, the regulating valve includes a valve seat, a water flow channel is axially provided on the valve seat, a valve stem is radially slidably provided on the valve seat, a connecting hole matching the water flow channel is provided on the valve stem, and a return spring is provided between the valve stem and the outer wall of the valve seat.

[0012] Furthermore, the second control component includes a water outlet pipe, in which a second one-way membrane flap and a fixed confluence seat are sequentially connected from back to front, and the front end of the fixed confluence seat is connected to a shape regulator via an elastic connecting rod.

[0013] Furthermore, the interior of the fixed busbar is a hollow structure, and a plurality of intersecting support rods are provided on the inner side wall of the fixed busbar, and the rear end of the elastic connecting rod is connected to the intersection of the plurality of support rods.

[0014] Furthermore, the shape regulator is in the shape of a water drop, with a pointed cone at the front end and a plurality of guide grooves provided on the middle side wall.

[0015] Furthermore, a hand-held handle is sleeved on the outside of the flushing pipe, and the hand-held handle is located on the rear side of the first control component.

[0016] The beneficial effects of the present invention are as follows: compared with the prior art, the present invention has the following improvements: 1. In the present invention, the first control component is provided with a first one-way diaphragm, a hemispherical pressure regulating disk and an elastic column. Water will flow out only when the water pressure is large enough to open the first one-way diaphragm; when the water impacts the hemispherical pressure regulating disk, the elastic column will be compressed, thereby consuming the impact potential energy of the water flow, adjusting the impact force of the water flow by itself, and thus enhancing the stability of the water flow pressure. At the same time, the water impacts the concave spherical surface of the hemispherical pressure regulating disk, and then flows back to the gap between the hemispherical pressure regulating disk and the connecting pipe, which can also achieve buffering and regulation of the water flow pressure, realize the regulation and control of the water pressure, and avoid excessive water pressure from damaging the patient's internal tissues and wound surface, affecting the surgical operation.

[0017] 2. In the present invention, a shape regulator is provided in the second control component. The shape regulator is in the shape of a water drop, with a pointed cone at the front end, a guide groove in the middle, and a rear end fixedly connected to an elastic connecting rod. After the water flow passes through the fixed confluence seat for integration, the water flow sprays out from the middle hole to the rear end face of the shape regulator, along the arc surface and the guide groove, converges to the front end conical surface, and flows out in a streamlined manner along the direction of the cone tip, thereby rectifying the flow into a streamlined column shape to prevent splashing. In addition, the elastic connecting rod is made of a flexible material and can be slightly deformed, so that the outlet end pipe can adapt to the position adjustment of the shape regulator whether it is in a vertical state or an inclined state, ensuring that the water flow is streamlined and does not splash in a flower-like manner.

[0018] 3. In the present invention, both the first control component and the second control component are provided with one-way valves, and the opening of the one-way valves is automatically controlled according to the water pressure. Therefore, after the water supply is stopped, when the water pressure in the pressure-stabilizing pipe in the middle is lower than that of the second one-way valve, the second one-way valve cannot be opened, and the flushing operation can be stopped. Compared with the existing flushing device which delays the outflow of all water in the pipeline after the water supply is stopped, the present invention can avoid the waste of water flow and medicine therein to the greatest extent.

DETAILED DESCRIPTION

[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0032] See attached Figure 1-11 A warm water flushing system for acoustic neuroma shown in the figure includes a flushing pipe 1, a hand-held handle 2 is provided on the outer front end of the flushing pipe 1, and the front end of the flushing pipe 1 is connected to a first control component for adjusting water pressure and flow, the front end of the first control component is connected to a pressure-stabilizing pipe 3, and the front end of the pressure-stabilizing pipe 3 is connected to a second control component for adjusting the water flow shape.

[0033] Specifically, the first control component includes a valve seat 4, on which a water flow channel 401 is axially provided, the front end of the water flow channel 401 is connected to the pressure-stabilizing pipe 3, and the rear end of the water flow channel 401 is connected to the flushing pipe 1. A valve stem 5 is radially provided on the valve seat 4, the valve stem 5 is slidably connected to the valve seat 4, the valve stem 5 can move up and down along the radial direction of the valve seat 4, and a return spring 6 is provided between the valve stem 5 and the outer side wall of the valve seat 4, a connecting hole 501 matching the water flow channel 401 is provided on the valve stem 5, and a clearance groove 402 for the movement of the valve stem 5 is provided in the valve seat 4. In order to prevent the valve stem 5 from rotating during the up and down movement, a convex ridge is radially provided in the valve seat 4, and a groove matching the convex ridge is provided on the valve stem 5. Through the mutual cooperation of the convex ridge and the groove, the sliding connection between the valve stem 5 and the valve seat 4 can be achieved, and the rotation of the valve stem 5 during the up and down movement can be prevented. It should be noted that the valve stem 5 and the valve seat 4 are tightly fitted, and the resistance generated between the two is sufficient to prevent the valve stem 5 from separating from the valve seat 4 by itself, but the two can be separated under the action of external force. When the valve stem 5 moves to the bottom of the valve seat 4, the connecting hole 501 is completely connected with the water flow channel 401, and the flushing water can enter the pressure-stabilizing pipeline 3 through the flushing pipe 1, the water flow channel 401 and the connecting hole 501, and finally flow out through the second control component. When the valve stem 5 moves to the top, the water flow channel 401 and the connecting hole 501 are staggered, and the valve stem 5 seals the water flow channel 401, and water cannot enter the pressure-stabilizing pipeline 3 through the water flow channel 401. The water output can be adjusted by adjusting the size of the connection between the water channel 401 and the connecting hole 501. In the present invention, the valve stem 5 and the valve seat 4 form a regulating valve structure, and the mutual cooperation between the two can be achieved using the existing pressure-controlled valve technology.

[0034] The first control component also includes a connecting pipe 7 arranged at the front end of the valve seat 4. The connecting pipe 7 is integrally formed with the valve seat 4, and the connecting pipe 7 is connected to the water flow channel 401. The front end of the connecting pipe 7 is connected to the pressure-stabilizing pipe 3. The connecting pipe 7 is provided with a first one-way diaphragm 8, a hemispherical pressure regulating disk 9, an elastic column 10 and a base 11 in sequence. The outer periphery of the first one-way diaphragm 8 is fixedly connected to the inner wall of the connecting pipe 7, and the interior is a multi-valve diaphragm. When the water pressure is small, the diaphragm is closed. When the water pressure exceeds its natural elastic closing value, the channel is opened, so that the water flow passes through the middle pore first, which can play a certain confluence role and make the water flow only pass in one direction. The base 11 is fixedly mounted on the inner side wall of the front end of the connecting tube 7, and a gap is provided between the base 11 and the inner side wall of the connecting tube 7 so that water can pass through. The elastic column 10 is connected to the rear end surface of the base 11, and the hemispherical pressure regulating disk 9 is fixedly provided at the rear end of the elastic column 10. The hemispherical pressure regulating disk 9 is a hollow hemispherical structure, and the outer diameter is smaller than the inner diameter of the connecting tube 7. The elastic column 10 is made of elastic material. When the water flow impacts the hemispherical pressure regulating disk 9, the elastic column 10 will be compressed, thereby consuming the impact potential energy of the water flow, adjusting the impact force of the water flow by itself, and then enhancing the stability of the water flow pressure. After the flushing water passes through the flushing pipe 1 and the valve seat 4 and enters the connecting pipe 7, the first one-way diaphragm flap 8 is first opened by the potential energy of its own water flow, and preferentially flows out from the middle pore of the first one-way diaphragm flap 8, and then directly impacts the concave spherical surface of the hemispherical pressure regulating disk 9, and then flows back to flow out from the gap between the hemispherical pressure regulating disk 9 and the connecting pipe 7, and finally flows into the pressure-stabilizing pipe 3 through the gap between the base 11 and the connecting pipe 7, thereby realizing the regulation and control of the water pressure and flow.

[0035] In some specific embodiments, the second control component includes a water outlet pipe 12, the rear end of which is connected to the front end of the pressure-stabilizing pipe 3, and the water outlet pipe 12 is provided with a second one-way membrane flap 13, a fixed confluence seat 14, an elastic connecting rod 15 and a shape regulator 16 in sequence. The front end of the water outlet pipe 12 is a conical water outlet, which is conducive to the confluence and outflow of water. The second one-way membrane flap 13 has the same structure as the first one-way membrane flap 8, and its outer periphery is fixedly connected to the inner wall of the water outlet pipe 12. The fixed confluence seat 14 is a conical structure with a small front and a large rear, and is also fixedly connected to the inner wall of the water outlet pipe 12, and the interior of the fixed confluence seat 14 is a hollow structure. A plurality of support rods 1401 are provided on the inner wall of the fixed confluence seat 14, and the plurality of support rods 1401 are connected together at the center of the fixed confluence seat 14, and the rear end of the elastic connecting rod 15 is connected to the intersection of the plurality of support rods 1401, and the front end of the elastic connecting rod 15 is connected to the shape regulator 16, and the elastic connecting rod 15 is made of a certain flexible and elastic material. Under the action of gravity, the front end of the shape regulator 16 can move slightly toward the direction close to the pipe wall of the water outlet pipe 12, and jointly with the pipe wall of the water outlet pipe 12 to enhance the water flow rectification effect, and the length and flexibility of the elastic connecting rod 15 can be changed as needed according to the offset angle and distance of the shape regulator 16, so as to adjust the specifications for the best rectification effect. The shape regulator 16 is in the shape of a water drop, with a pointed cone at the front end, a plurality of guide grooves 1601 on the middle side wall, and a rear end fixedly connected to the elastic connecting rod 15. After the water flow is integrated through the fixed confluence seat 14, the water flow is ejected from between the plurality of support rods 1401 in the middle of the fixed confluence seat 14, flows to the rear end surface of the shape regulator 16, and converges to the front conical surface along the arc surface and the guide grooves 1601, and flows out in a streamlined manner along the direction of the cone tip, thereby rectifying the flow into a streamlined column shape and preventing splashing. It should be noted here that when the outlet pipe 12 is in a vertical state, under the action of gravity, the shape regulator 16 and the elastic connecting rod 15 both remain in a vertical state, and the water flow flows out in a streamlined manner from the front end conical tip direction of the shape regulator 16 through the middle of the outlet pipe 12. When the outlet pipe 12 is in an inclined state, the elastic connecting rod 15 is bent under the gravity of the shape regulator 16, so that the shape regulator 16 contacts the inner wall of the outlet pipe 12. After passing through the front end taper of the shape regulator 16, the water flows out in a streamlined manner along the side wall of the outlet pipe 12.

[0036] Since the front end and the rear end of the pressure-stabilizing pipe 3 are respectively provided with a second one-way diaphragm flap 13 and a first one-way diaphragm flap 8, water of a certain pressure will be retained in the pressure-stabilizing pipe 3. As the valve stem 5 presses the water inlet, the water pressure in the pressure-stabilizing pipe 3 gradually increases. When the water pressure in the pressure-stabilizing pipe 3 is large enough to open the second one-way diaphragm flap 13, the water can enter the second control component and eventually flow out. When the water supply is stopped, the water pressure in the pressure-stabilizing pipe 3 will gradually decrease, so that the second one-way diaphragm flap 13 will gradually close and stop the water from flowing out. In this way, the start and stop control of the water flow can be carried out quickly and accurately, avoiding the situation in which the water flow in the pipe behind the valve will be delayed in flowing out when the valve is directly controlled, and the loss of water flow and internal drugs is also saved.

[0037] The acoustic neuroma warm water flushing system of the present invention is used for flushing operations during acoustic neuroma surgery. When it is necessary to flush the tissue wound in the surgical field during the operation, the front end of the water outlet pipe 12 is aligned with the wound or tissue that needs to be flushed, the handheld handle 2 is held, the water source is connected, and the valve stem 5 is pressed downward to connect the water flow channel 401 with the connecting hole 501. The flushing water enters the connecting pipe 7 through the flushing pipe 1, the water flow channel 401 and the connecting hole 501, and the first one-way membrane flap 8 is opened by the potential energy of its own water flow, and flows out from the middle pore of the first one-way membrane flap 8 first, and then directly impacts the concave spherical surface of the hemispherical pressure regulating disk 9, and then flows back to the gap between the hemispherical pressure regulating disk 9 and the connecting pipe 7, and finally flows into the pressure-stabilizing pipe 3 through the gap between the base 11 and the connecting pipe 7, so as to realize the regulation and control of water pressure and flow.

[0038] After the water flowing out of the connecting pipe 7 enters the pressure-stabilizing pipe 3, when the water pressure in the pressure-stabilizing pipe 3 is large enough to open the second one-way membrane flap 13, the water flows out from the middle pore of the second one-way membrane flap 13 first, and after being integrated by the fixed confluence seat 14, the water flows out from between the multiple support rods 1401 in the middle of the fixed confluence seat 14, flows to the rear end face of the morphology regulator 16, and converges to the front end conical surface along the arc surface and the guide groove 1601, and flows out in a streamlined manner along the direction of the cone tip, thereby rectifying the water into a streamlined column shape and preventing splashing, thereby achieving control of the water flow shape.

[0039] After the water supply is stopped, the water pressure in the pressure-stabilizing pipe 3 will gradually decrease, so that the second one-way membrane flap 13 will gradually close and stop the water outflow, so that the start and stop of the water flow can be quickly and accurately controlled, avoiding the situation where the water flow in the pipe behind the valve will be delayed in flowing out when the valve is directly controlled, and also saving water flow and internal drug loss.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
