Description

Technical Field

[0001] The utility model relates to the technical field of surgical auxiliary instruments, in particular to a surgical auxiliary device. Background Art

[0002] During hysteroscopic surgery, normal saline solution is usually needed to perform uterine distension. One operation generally requires 2 to 3 bags of 3000 ml of normal saline solution, and sometimes even as many as 8 bags. This involves the operation of replacing the normal saline bag. During the operation, most of the doctors and nurses' attention is focused on the surgical operation, and they will not always observe the remaining normal saline solution. This will result in the situation where the normal saline solution drips out but no one notices. During the uterine distension process, a uterine distension pump is used to ensure the continuous flow of normal saline solution, which will cause gas to enter the human body. In severe cases, air embolism will occur, affecting the patient's life safety.

[0003] When medical staff find that the saline bag needs to be replaced in time, in order to prevent bubbles from entering the human body, the ongoing operation needs to be stopped immediately. Then, the operation can be continued after the nurse replaces the saline bag and completes the exhaust operation. The saline bag needs to be replaced many times in one operation, and the operation needs to be stopped for each replacement. This will undoubtedly affect the doctor's surgical process and the treatment of the patient. It will also prolong the operation time and increase the fatigue of many medical staff.

The left and right ends of the conversion box 9 are respectively fixedly connected to the needle through the liquid inlet pipe 11, and the lower end of the conversion box 9 is fixed with a liquid outlet pipe 12.

[0019] In order to enable the extension rod 5 to move up and down, the extension rod 5 is slidably connected to the slider 4 on the front side, and the upper end of the extension rod 5 is fixedly connected to the slider 4 on the front side via a compression spring. The rear end of the extension rod 5 is fixed with an inclined plate 13 which is lower on the left and higher on the right and can be inserted into the slider 4 on the front side, and the front end of the slider 4 on the rear side is fixed with a fixed rod 14 which can contact the inclined plate 13.

[0020] In order to enable the rocker arm 6 to swing left and right, a rotating column in the front-to-back axis is fixed to the lower end of the rocker arm 6, and the rotating column is rotatably connected to the main body box 1. A fixed column 15 located directly below the rotating column and in the front-to-back axis is fixed in the main body box 1. An auxiliary rod in the front-to-back axis is fixed to the front end of the rocker arm 6, and the auxiliary rod is fixedly connected to the fixed column 15 via a spring. Two left-to-right opposite and front-to-back axial stop columns 16 are fixed in the main body box 1. The rocker arm 6 is located between the two stop columns 16 and can contact the stop columns 16.

[0021] In order to make the support plate 8 rotatable, a front-to-back axial rotation shaft is fixed in the middle of the support plate 8 . The rotation shaft is located between the two slide bars 7 and is rotatably connected to the main box 1 .

[0022] In order to make the conversion box 9 detachable and connected to the main box 1, the front end of the main box 1 is provided with a storage groove coaxial with the rotating shaft, and the conversion box 9 can be inserted into the storage groove. The front end of the main box 1 is provided with multiple makeshift grooves connected to the storage groove, and the liquid inlet pipe 11 and the liquid outlet pipe 12 can be inserted into the makeshift groove. A plurality of elastic strips 17 evenly distributed along the circumferential direction are fixed in the storage groove.

[0023] In order to make the baffle 10 detachable and connected to the support plate 8, a connecting disk 18 is coaxially fixed to the front end of the rotating shaft. The front end of the connecting disk 18 is inserted into the storage slot and is provided with an oblique slot. The rear end of the conversion box 9 is coaxially connected to a connecting column 19. The front end of the connecting column 19 is fixedly connected to the middle part of the baffle 10. The baffle 10 contacts the inner surface of the conversion box 9. The rear end of the connecting column 19 passes through the conversion box 9 and is fixed with a connecting rod 20 that can be inserted into the oblique slot.

[0024] In order to prevent the excessive weight of the physiological saline bag from damaging the tension spring, the left and right sides of the upper end of the hook 2 are fixedly connected to the main box 1 via protective belts 21 respectively.

[0025] In order to promptly remind medical staff to replace the used physiological saline bag, infusion alarms 22 are fixed to the left and right ends of the main box 1 respectively, and the liquid inlet tube 11 can be inserted into the infusion alarm 22.

[0026] In order to prevent gas from entering the human body, a liquid storage bag 23 is fixed to the lower end of the liquid outlet tube 12, and a connector 24 is fixed to the lower end of the liquid storage bag 23.

[0027] In order to facilitate fixing the position of the main box 1, arc-shaped blocks 25 are fixed on the upper and lower sides of the rear end of the main box 1 respectively, and a front-to-rear axial positioning groove is provided at the left end of the arc-shaped block 25. An arc-shaped pressing block 26 is provided behind the arc-shaped block 25, and a positioning column that can be inserted into the positioning groove is fixed at the left end of the pressing block 26. The right end of the pressing block 26 is rotatably connected to a screw, and the screw is threadedly connected to the right end of the arc block 25.

[0028] When the utility model is in use, the initial state is that the positioning column is not inserted into the positioning groove, the conversion box 9 is not connected to the main box 1, the lower end of the inclined plate 13 is in contact with the fixed rod 14, the extension rod 5 is located above the swing rod 6, the swing rod 6 is in contact with the left side blocking column 16 and is in an inclined shape with the left side higher and the right side lower, the support plate 8 is in an inclined shape with the left side lower and the right side higher, the inclined groove is in an inclined shape with the left side lower and the right side higher, and the protective belt 21 is in a relaxed state;

[0029] When it is needed, the arc block 25 is brought into contact with the vertical rod portion of the infusion stand, the positioning column of the pressing block 26 is inserted into the positioning groove, and the screw is rotated. The pressing block 26 is connected to the arc block 25 and squeezes the infusion stand, thereby fixing the main box 1 on the infusion stand. After both pressing blocks 26 squeeze the infusion stand, the main box 1 is firmly fixed on the infusion stand.

[0030] Take out a new sterile conversion box 9 and insert the connecting rod 20 into the chute. If the direction of the connecting rod 20 is different from that of the chute, manually rotate the connecting rod 20 so that the connecting rod 20 becomes an inclined shape with the left side lower and the right side higher, and then insert it into the chute. At this time, the baffle 10 is in an inclined shape with the left side higher and the right side lower. The left inlet pipe 11 is connected to the outlet pipe 12 through the conversion box 9. The right inlet pipe 11 is not connected to the outlet pipe 12 and the left inlet pipe 11 under the cover of the baffle 10. Connect the connector 24 to the uterine expansion tube and insert the two inlet pipes 11 into the infusion alarm 22 on the corresponding side.

[0031] After the cam 14 is in the process of being lifted up, the cam 14 is in the process of being lifted up, and the cam 14 is in the process of being lifted up, and the cam 14 is in the process of being lifted up, and the cam 14 is in the process of being lifted up, and the cam 14 is in the process of being lifted up, and the cam 14 is in the process of being lifted up.

[0032] Due to the presence of the protective belts 21, after the hook 2 moves downward a certain distance, the two protective belts 21 are tightened, and the hook 2 stops moving downward. Since the weight of a 3000 ml saline bag is much greater than the weight of an empty saline bag, if one wants to rely on a tension spring to determine the liquid content in the saline bag, the smaller the tension of the tension spring, the more accurate the result. By setting the protective belts 21, the protective belts 21 are used to support the weight of the saline bag, thereby preventing damage to the tension spring and ensuring the accuracy of measuring the liquid content in the saline bag.

[0033] The needle is inserted into the corresponding saline bag, and the liquid in the saline bag flows into the liquid storage bag 23 and is stored in the liquid storage bag 23, so that the upper half of the liquid storage bag 23 contains gas and the lower half contains more liquid. The liquid then enters the human body through the connector 24 and the uterine expansion tube, ensuring the normal progress of the operation;

[0034] When the liquid content in the saline bag is so low that its weight is less than the tension of the tension spring, as the liquid continues to decrease, the left pull rope 3 pulls the saline bag upward under the action of the tension spring, and the protective belt 21 becomes relaxed. The front slider 4 simultaneously drives the extension rod 5 to move rightward. After moving a certain distance to the right, the extension rod 5 contacts the swing rod 6. Since the lower end of the extension rod 5 is not in contact with the swing rod 6 at this time, the extension rod 5 does not move upward but pushes the swing rod 6 to swing to the right. The rotating shaft and the main box 1 are tightly connected in rotation. Therefore, even if the swing rod 6 no longer presses the left slide bar 7, the support plate 8 will not swing.

[0035] When the bottle is in the liquid-carrying bag, the left end of the bottle is in the liquid-carrying bag, and the bottle is in the liquid-carrying bag, and the bottle is in the liquid-carrying bag, and the bottle is in the liquid-carrying bag, and the bottle is in the liquid-carrying bag, and the bottle is in the liquid-carrying bag, and the bottle is in the liquid-carrying bag, and the bottle is in the liquid-carrying bag, and the bottle is in the liquid-carrying bag, and the bottle is in the liquid-carrying bag, and the bottle is in the liquid-carrying bag, and the bottle is in the liquid-carrying bag, and the bottle is in the liquid-carrying bag, and the bottle is in the liquid-carrying bag, and the bottle is in the liquid-carrying bag, and the bottle is in the liquid-carrying bag, and the bottle is in the liquid-carrying bag, and the bottle is in the liquid-carrying bag, and the bottle is in the liquid-carrying bag, and the bottle is in the liquid-carrying bag, and the bottle is in the liquid-carrying bag, and the bottle is in the liquid-carrying bag, and the bottle is in the liquid-carrying bag, and the bottle is in the liquid-carrying bag, and the bottle is in the liquid-carrying bag, and the bottle is in the liquid-carrying bag

[0036] After the right side physiological saline bag starts to supply liquid, the bubbles in the liquid inlet pipe 11 enter the liquid storage bag 23 through the conversion box 9 and the liquid outlet pipe 12. Since the upper part of the liquid storage bag 23 is air and the lower part is liquid, the bubbles will remain in the upper part after entering the liquid storage bag 23, and will not enter the liquid in the lower side, thereby ensuring that the liquid entering the patient's body is still pure liquid without bubbles, and there is no need to stop the operation to perform the exhaust operation, which ensures the smoothness of the operation. At this time, the new physiological saline bag has started to supply liquid, and the medical staff has enough time to perform the liquid change operation. The alarm of the infusion alarm 22 will also remind the medical staff. At this time, the medical staff takes out the new physiological saline bag, hangs it on the hook 2 on the left, and connects it to the needle on the left, and removes the used physiological saline bag. At this time, the extension rod 5 moves to the extreme position on the left again, and the protective belt 21 is in a taut stretched state again.

[0037] When the liquid on the right side is used up, the infusion alarm 22 on the right side sounds an alarm, and the slider 4 on the rear side pushes the swing rod 6 from the inclined shape with the left side lower and the right side higher to the inclined shape with the left side higher and the right side lower. The support plate 8 swings again under the push of the swing rod 6 and the slider 7, so that the liquid inlet pipe 11 on the left is connected with the liquid outlet pipe 12, and the liquid inlet pipe 11 on the right is disconnected from the liquid outlet pipe 12. This alternating reciprocating process realizes uninterrupted liquid replacement operation.

[0038] After the operation is over, there is nothing hanging on the two hooks 2. At this time, the two sliders 4 move relative to each other under the action of the tension spring, and the rocker arm 6 swings. After the two sliders 4 move relative to each other for a certain distance, the fixed rod 14 contacts the inclined plate 13 and pushes the extension rod 5 upward under the action of the inclined surface of the inclined plate 13, so that the extension rod 5 is located above the rocker arm 6, and the extension rod 5 no longer affects the rocker arm 6. At this time, the rocker arm 6 is pushed by the slider 4 on the rear side to become an inclined shape with the left higher and the right lower. The conversion box 9 is moved forward to move the connecting rod 20 out of the inclined slot. The conversion box 9, the liquid inlet pipe 11, the liquid outlet pipe 12, the needle, the liquid storage bag 23, and the connector 24 can be discarded. A new sterile one can be used next time it is needed, thereby ensuring the sterile operation of the operation.

[0039] In the present invention, a sealing ring is provided between the connecting column 19 and the conversion box 9 to increase the sealing performance, prevent liquid leakage, and ensure a sterile environment for the liquid.

[0040] The utility model has the advantages of simple structure, convenient operation, novel concept and strong practicality. By arranging structures such as a pull rope, a slider, a tension spring and a hook, the weight of the physiological saline bag is used to judge the content of the liquid, so that the physiological saline bag is automatically replaced when the liquid is used up, and a situation in which an empty bag cannot be replaced in time is prevented. The physiological saline bag is supported by the provision of a protective belt, and the tension spring is protected, thereby improving the accuracy of the result. The medical staff is reminded by the infusion alarm, so that the medical staff has sufficient time to replace the liquid. In addition, the gas in the liquid inlet tube is stored by the provision of the liquid storage bag, so that the gas cannot enter the human body, and there is no need to stop the operation to perform the exhaust operation, so that the operation can be smoothly completed without stopping the operation in the middle due to liquid replacement, thereby improving the work efficiency of the medical staff and reducing the discomfort of the patient.
