Abstract
Description
Technical Field
[0001] This utility model relates to the field of rinsing device technology, and in particular to a suction device that can be used for both rinsing and suction. Background Technology
[0002] In surgical procedures, suction tubes and irrigation tubes are commonly used to assist in aspirating irrigation fluid and rinsing away intraoperative or postoperative residues. Simultaneous operation of both tubes by medical staff is extremely inconvenient, especially during minimally invasive surgeries such as thoracic surgeries. The limited surgical incision restricts the simultaneous operation of suction and irrigation tubes, inevitably increasing surgical time. Furthermore, the need for medical staff to switch between suction and irrigation tubes as needed is highly inconvenient and requires prolonged periods of intense concentration, leading to fatigue and negatively impacting treatment. Therefore, a suction device that allows for easy switching between these functions is needed to improve surgical efficiency. Utility Model Content
[0003] The purpose of this invention is to solve the problem that switching between the suction tube and the irrigation tube affects the duration of surgical treatment in the prior art, and to propose a dual-purpose suction and irrigation device.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A suction device that can be used for both flushing and suction includes a mounting base. A suction channel and a flushing chamber are respectively formed on one side of the mounting base, with the suction channel located inside the flushing chamber. A suction tube is fixed to one end of the suction channel, and a flushing tube is sleeved around the outside of the suction tube. Both the suction tube and the flushing tube are arc-shaped. A pressure relief hole is formed on the top side of the suction tube. A push plate is tightly fitted to the outer side of the suction tube against the inner wall of the flushing tube. A pressure point block is formed on the top of the push plate, with an arc-shaped top surface. A contact hole communicating with the pressure relief hole is formed on the arc surface of the pressure point block. A protective cap is inserted into the inner wall of the suction tube opening.
[0006] Preferably, the side and port arc surfaces of the flushing pipe are respectively provided with side flushing holes and direct spray holes, and one end of the flushing pipe is inserted into one end of the flushing chamber.
[0007] Preferably, a mating groove is provided on the inner wall of one end of the flushing pipe, and the inner wall of the mating groove is fitted to the end of the suction pipe.
[0008] Preferably, a rectangular groove is provided on the side of the rinsing tube, and the top of the acupressure block is inserted into the inner wall of the rectangular groove.
[0009] Preferably, one end of the protective cap is fixed with a support arm, and one end of the support arm is fixed to the inner wall of the suction tube.
[0010] Preferably, an installation hole is provided on the other side of the assembly base, a water pressure plate is inserted into the inner wall of the installation hole, and two damping plates are fixed to the side of the water pressure plate, with one end of each damping plate inserted into the inner wall of the installation hole.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] 1. This utility model, through the combined setting of pressure relief hole and contact hole, allows medical staff to push the finger pressure block to connect or close the contact hole with the pressure relief hole, completing different combinations of suction and flushing work. This can reduce the time of surgical treatment and reduce the difficulty for medical staff to operate the device for flushing and suction of flushing fluid. In addition, the flushing fluid can be temporarily absorbed by pressing the contact hole, which effectively improves the practicality of the device in the surgical treatment process.
[0013] 2. This utility model features a curved suction tube and a flushing tube. The curved suction tube and flushing tube allow medical staff to easily change the orientation of the tube openings during minimally invasive surgery or routine surgery, thereby improving the flexibility of the device and making it easier for medical staff to flush away residues or aspirate flushing fluid.
[0014] 3. By setting a protective cap, this utility model can prevent the end of the pipe from directly contacting the surface of the organ, thus avoiding damage to the organ during the adsorption of the flushing fluid. In addition, the protective cap can increase the flow rate at the suction port and prevent solid residues from accumulating and clogging the port. Attached Figure Description

[0022] Example, refer to Figures 1 to 3 A suction device that can be used for both flushing and suction includes a mounting base 1. A mounting hole 16 is provided on the other side of the mounting base 1. A water pressure plate 17 is inserted into the inner wall of the mounting hole 16. Two damping plates 18 are fixed to the side of the water pressure plate 17. One end of each of the two damping plates 18 is inserted into the inner wall of the mounting hole 16.
[0023] The damping plate 18 is existing technology. Its purpose is to facilitate the change of the flow rate of the flushing fluid by moving the water pressure plate 17 to change the distance from the inlet of the flushing chamber 3 during use.
[0024] A suction channel 2 and a rinsing chamber 3 are respectively provided on one side of the assembly base 1. The suction channel 2 is located inside the rinsing chamber 3. A suction tube 4 is fixed at one end of the suction channel 2. A rinsing tube 5 is sleeved on the outside of the suction tube 4. The tube bodies of the suction tube 4 and the rinsing tube 5 are both arc-shaped. A side rinsing hole 11 and a direct spray hole 12 are respectively provided on the side and the arc surface of the port of the rinsing tube 5.
[0025] The suction tube 4 and the irrigation tube 5 are arranged in an arc shape. This is to make it easier for medical staff to change the orientation of the ports of the suction tube 4 and the irrigation tube 5 by rotating their wrists during use, so as to rinse areas that are difficult to rinse, such as the inside of the chest cavity.
[0026] One end of the flushing tube 5 is inserted into one end of the flushing chamber 3. A docking groove 13 is provided on the inner wall of one end of the flushing tube 5. The inner wall of the docking groove 13 is fitted to the end of the suction tube 4. A rectangular groove 14 is provided on the side of the flushing tube 5. The top of the acupressure block 8 is inserted into the inner wall of the rectangular groove 14. A pressure relief hole 6 is provided on the top side of the suction tube 4. A push plate 7 is tightly attached to the outer side of the suction tube 4 and the inner wall of the flushing tube 5. Acupressure block 8 is provided on the top of the push plate 7. The top of the acupressure block 8 is arc-shaped, and a contact hole 9 connecting the pressure relief hole 6 is provided on the arc surface of the acupressure block 8.
[0027] The purpose of the arc-shaped top of the acupressure block 8 is to facilitate placing the finger on the touch hole 9 during use. Firstly, the touch hole 9 increases the friction between the finger and the contact surface of the acupressure block 8. Secondly, it can be used when it is necessary to temporarily absorb or increase the speed of rinsing fluid absorption, thus improving the practicality and convenience of the device during use.
[0028] A protective cap 10 is inserted into the inner wall of the suction tube 4. A support arm 15 is fixed to one end of the protective cap 10, and one end of the support arm 15 is fixed to the inner wall of the suction tube 4.
[0029] The protective cap 10 is made of silicone. This serves two purposes: first, to reduce damage to organs when the device is inserted; and second, to increase the flow rate at the suction tube 4 during negative pressure suction, thus preventing solid residues from clogging the tube opening.
[0030] Before use, the suction channel 2 and the flushing chamber 3 are connected to the negative pressure pipe and the flushing liquid pipe, respectively. During use, the distance from the opening of the flushing chamber 3 is changed by pushing and pulling the water pressure plate 17, thereby changing the flow rate of the flushing liquid. The size of the overlap between the pressure relief hole 6 and the contact hole 9 is changed by pushing the finger pressure block 8, thereby changing the suction speed of the suction tube 4. When it is necessary to temporarily absorb the flushing liquid, the finger is pressed on the contact hole 9 to increase the negative pressure of the suction tube 4 and increase the speed of absorbing the flushing liquid. Releasing the finger will restore the original suction speed.
[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
