Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to a high-stability pneumoperitoneum machine for abdominal surgery. Background Art

[0002] During minimally invasive surgery, since the human organs or other tissues are squeezed together, there is not enough space for observation and surgery. At this time, a pneumoperitoneum machine is needed to provide air pressure to expand the inner cavity in order to provide appropriate surgical space and surgical field of view. Unstable air pressure will cause soft tissue to shift with the change of air pressure, affecting the doctor's judgment of the precise location of the surgical site. Excessive air pressure can have serious effects on some patients.

[0003] The existing conventional insufflator has large fluctuations in air pressure during use, which can easily cause damage to the patient's internal body when the staff performs surgery on the patient, and the air pressure during carbon dioxide delivery cannot be adjusted during use. At the same time, the staff will debug the insufflator according to the usage during surgery. There are many bacteria on the surface of the insufflator. After the staff has debugged the insufflator, it will come into contact with the patient's body, causing bacteria to be contaminated on the patient's body, which can easily cause wound infection in the patient. The surface of the insufflator cannot be wiped and disinfected during use. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a high-stability pneumoperitoneum machine for abdominal surgery.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] Preferably, the protective mechanism includes a movable plate, which is slidably installed in the installation hole. A brush is installed on the side of the movable plate close to the pneumoperitoneum machine body. A placement hole is opened through one end of the movable plate, and a partition is installed on the inner wall of the placement hole.

[0008] Preferably, shielding cloth is installed on both sides of the partition, the end of the shielding cloth away from the partition passes through the placement hole and is installed with a card strip, one side of the card strip is installed inside the placement hole, and the inner wall of the two installation holes close to the protective plate is provided with a card slot matching the card strip.

[0009] Preferably, the fixing mechanism includes a connecting plate, which is slidably installed in the connecting hole, one end of the connecting plate is installed on the side of the protective plate, and the other end of the connecting plate is installed with a limit block, which is located inside the pneumoperitoneum machine body.

[0010] Preferably, a groove is provided on the top of the connecting plate, a rubber bag is installed on the inner bottom of the groove, a connecting head is installed on one end of the connecting plate close to the limit block, and a connecting block is installed on the top of the connecting plate close to the protective plate. Both the connecting head and the connecting block are connected to the interior of the rubber bag.

[0011] Preferably, the connecting block is located between the pneumoperitoneum machine body and the protective plate, and a protective groove is provided at an inner top of the connecting hole close to one end of the protective plate, and the connecting block is located in the protective groove.

[0012] Preferably, the limiting mechanism includes a lifting plate, a rotating groove is provided on the top of the protective plate, and the rotating groove is connected to the installation groove, and sliding grooves are provided on the inner walls on both sides of the installation groove in the length direction, and a slider is slidably installed in the sliding groove.

[0013] Preferably, fixing rods are installed on the top ends of both sides of the lifting plate, and the ends of the two fixing rods away from the lifting plate are rotatably installed on the opposite surfaces of the two sliding blocks.

[0014] Preferably, the bottom end of the lifting plate passes through the mounting groove and is installed with a clamping plate, and the top of the clamping plate is located on both sides of the lifting plate and is provided with through holes in the length direction.

[0015] Preferably, sliding grooves are provided on the inner walls on both sides of the mounting hole in the length direction, and the two ends of the movable plate are slidably mounted in the two sliding grooves respectively.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The rubber bag in the present invention can slow down the flow rate of the delivered carbon dioxide to prevent the carbon dioxide from flowing too fast and causing harm to the patient's body. When the air pressure inside the rubber bag is relatively high, the top of the rubber bag abuts against the inner top of the connecting hole, and the two ends of the top of the rubber bag are respectively located inside and outside the insufflator body. When in use, the friction between the rubber bag and the inner wall of the connecting hole can better fix the position of the connecting plate, and when in use, the rubber bag can better fix the position of the protective plate and the insufflator body. At the same time, the rubber bag and the clamping plate cooperate with each other to limit the up and down positions and left and right positions of the protective plate, the insufflator body and the connecting plate, so that the insufflator body is more stable when in use.

[0018] 2. The staff can hold the movable plate and use the brush on the movable plate to wipe the surface of the insufflator body to prevent dust from appearing on the surface of the insufflator body. After wiping the surface of the insufflator body, the staff can apply disinfectant on the brush and use the brush to wipe and disinfect the control panel of the insufflator body to prevent the staff's hands from coming into contact with the control panel of the insufflator body when the staff needs to debug the insufflator body during surgery, causing dust and bacteria on the surface of the insufflator body to be contaminated on the staff's hands, resulting in bacteria coming into contact with the patient's body when the staff performs surgery on the patient. This can provide better protection for the patient during use.

[0019] 3. The card strip drives the shielding cloth out of the placement hole, and the two card strips are respectively inserted into the two card slots. The shielding cloth can cover and protect the control panel of the insufflator body, preventing external dust from falling on the control panel when the insufflator body is stored, and can better protect the control panel of the insufflator body. When the shielding cloth is protecting the control panel of the insufflator body, because the brush abuts against the control panel of the insufflator body, the brush can fix the position of the movable plate and prevent the movable plate from sliding in the installation hole.

[0020] 4. The clamping plate can clamp and fix the insufflator body when in use, making the insufflator body more stable when in use, and will not shake or move. When in use, the staff can wrap the delivery tube through the through hole and install it on the clamping plate to prevent the delivery tube from contacting the ground. At the same time, when in use, the staff can hook the end of the delivery tube away from the insufflator body into the through hole. The through hole can store the air outlet end of the delivery tube for a short time, making it convenient for the staff to take the delivery tube for use. The two clamping plates can be moved to the top of the insufflator body, and the through holes on the two clamping plates are connected to each other. The staff can lift the insufflator body through the clamping plate and the through hole, which is more convenient when the insufflator body needs to be moved. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] 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. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] Reference Figure 1-7A high-stability pneumoperitoneum machine for abdominal surgery includes a pneumoperitoneum machine body 1, with protective plates 2 installed at both ends of the pneumoperitoneum machine body 1, a mounting groove 19 is provided on the side of the protective plate 2 away from the pneumoperitoneum machine body 1, and a limiting mechanism is installed inside the mounting groove 19, and a limiting plate 3 and a mounting plate 4 are respectively installed at both ends of the side of the protective plate 2 close to the pneumoperitoneum machine body 1, and the limiting plate 3 and the mounting plate 4 are respectively installed on both sides of the pneumoperitoneum machine body 1, and a mounting hole 5 is provided at the end of the side of the mounting plate 4 away from the protective plate 2, and a protective mechanism is installed in one of the mounting holes 5, and connecting holes 26 are provided at both ends of the pneumoperitoneum machine body 1, and a fixing mechanism is installed in the connecting hole 26.

[0031] As a technical optimization solution of the present invention, the protective mechanism includes a movable plate 6, which is slidably installed in the installation hole 5. A brush 9 is installed on the side of the movable plate 6 close to the pneumoperitoneum machine body 1. A placement hole 11 is opened through one end of the movable plate 6, and a partition 12 is installed on the inner wall of the placement hole 11. When in use, the staff can wipe the control panel and surface of the pneumoperitoneum machine body 1 through the movable plate 6 and the brush 9 thereon. At the same time, when wiping the pneumoperitoneum machine body 1, the staff can apply disinfectant on the brush 9. When the staff needs to debug the pneumoperitoneum machine body 1 during surgery, it can prevent bacteria and dust on the surface of the pneumoperitoneum machine body 1 from getting on the hands of the staff, and can better protect the patient when the staff performs surgery on the patient.

[0032] As a technical optimization solution of the present invention, shielding cloths 13 are installed on both sides of the partition 12. The end of the shielding cloth 13 away from the partition 12 passes through the placement hole 11 and is installed with a clamping strip 10. One side of the clamping strip 10 is installed inside the placement hole 11. The two mounting holes 5 are close to the inner wall of the protective plate 2 on one side and are provided with a clamping slot 8 matching the clamping strip 10. After the use of the pneumoperitoneum machine body 1 is completed, the staff can move the movable plate 6 so that the brush 9 on the movable plate 6 can disinfect and wipe the control panel of the pneumoperitoneum machine body 1 again. At the same time, after the surface of the pneumoperitoneum machine body 1 is disinfected and wiped, the staff can use the shielding cloth 13 to cover and protect the control panel of the pneumoperitoneum machine body 1 to prevent external dust from falling on the surface of the pneumoperitoneum machine body 1 when the pneumoperitoneum machine body 1 is stored.

[0033] As a technical optimization solution of the present invention, the fixing mechanism includes a connecting plate 14, which is slidably installed in the connecting hole 26, one end of the connecting plate 14 is installed on the side of the protective plate 2, and the other end of the connecting plate 14 is installed with a limiting block 15, which is located inside the pneumoperitoneum machine body 1. When in use, the connecting plate 14 can better support the positions of the protective plate 2, the limiting plate 3 and the mounting plate 4. At the same time, the connecting plate 14 can guide the movement of the protective plate 2, and the limiting block 15 can limit the moving distance of the protective plate 2.

[0034] As a technical optimization solution of the present invention, a groove 16 is provided at the top of the connecting plate 14, and a rubber bag 17 is installed at the inner bottom of the groove 16. A connecting head 29 is installed at the end of the connecting plate 14 close to the limit block 15, and a connecting block 28 is installed at the end of the top of the connecting plate 14 close to the protective plate 2. The connecting head 29 and the connecting block 28 are both connected to the interior of the rubber bag 17. When in use, the rubber bag 17 can store the gas delivered by the pneumoperitoneum machine body 1 for a short time. After the gas enters the rubber bag 17, the rubber bag 17 can slow down the speed of the gas.

[0035] As a technical optimization solution of the present invention, the connecting block 28 is located between the pneumoperitoneum machine body 1 and the protective plate 2, and a protective groove 27 is opened at the inner top of the connecting hole 26 near one end of the protective plate 2. The connecting block 28 is located in the protective groove 27. After the pneumoperitoneum machine body 1 is used, the connecting block 28 can be moved into the protective groove 27. The protective groove 27 can better protect the connecting block 28 and prevent external dust from falling into the connecting block 28.

[0036] As a technical optimization solution of the present invention, the limiting mechanism includes a lifting plate 22, a rotating groove 18 is opened on the top of the protective plate 2, and the rotating groove 18 is connected to the installation groove 19. The inner walls on both sides of the installation groove 19 are provided with sliding grooves 20 in the length direction, and a slider 21 is slidably installed in the sliding groove 20. When in use, the lifting plate 22 can rotate in the rotating groove 18, so that the position of the lifting plate 22 can be adjusted according to the usage conditions during use.

[0037] As a technical optimization solution of the present invention, fixed rods 25 are installed on the top of both sides of the lifting plate 22. The two fixed rods 25 are rotatably installed on the opposite surfaces of the two sliders 21 at one end away from the lifting plate 22. When in use, the lifting plate 22 can be rotated in the rotation groove 18 through the fixed rods 25. At the same time, when in use, the lifting plate 22 slides up and down in the installation groove 19 through the slider 21. The height position of the lifting plate 22 can be adjusted according to the usage situation during use.

[0038] As a technical optimization solution of the present invention, the bottom end of the lifting plate 22 passes through the installation groove 19 and is installed with a clamping plate 23. The top of the clamping plate 23 is located on both sides of the lifting plate 22 and is provided with through holes 24 in the length direction. When in use, the staff can wrap the carbon dioxide delivery tube around the through hole 24, and the end of the delivery tube away from the pneumoperitoneum machine body 1 can also be hooked in the through hole 24. When in use, the delivery tube can be stored for a short time, making it more convenient for the staff to take the delivery tube.

[0039] As a technical optimization solution of the present invention, sliding grooves 7 are provided on the inner walls of both sides of the mounting hole 5 in the longitudinal direction, and the two ends of the movable plate 6 are respectively slidably mounted in the two sliding grooves 7. When in use, the movable plate 6 can be moved within the mounting hole 5 through the sliding grooves 7, making it convenient for staff to wipe and disinfect the surface of the pneumoperitoneum machine body 1 during use.

[0040] When the present invention is in use, the staff connects the connector 29 to the carbon dioxide outlet pipe inside the insufflator body 1, places the insufflator body 1 on a designated placement rack, and pulls the protective plates 2 at both ends of the insufflator body 1 toward the end away from the insufflator body 1, so that the lifting plates 22 on the two protective plates 2 are respectively located on both sides of the placement rack, and the clamping plates 23 are located at the bottom of the placement rack. The staff pushes the protective plates 2 so that the sides of the protective plates 2 abut against the two sides of the placement rack, and adjusts the height of the lifting plates 22 through the slider 21 so that the top of the clamping plate 23 abuts against the bottom of the placement rack. The clamping plate 23 and the insufflator body 1 can then clamp the placement rack and fix the position of the insufflator body 1, making the insufflator body 1 more stable when in use and preventing it from falling or shaking.

[0041] The staff connects one end of the carbon dioxide delivery tube used by the outside world to the connecting block 28. The carbon dioxide delivered from the inside of the insufflator body 1 enters the rubber bag 17 through the outlet pipe. The rubber bag 17 can slow down the flow rate of the delivered carbon dioxide to prevent the carbon dioxide from flowing too fast and causing harm to the patient's body. When carbon dioxide enters the rubber bag 17, the rubber bag 17 will expand, causing the top of the rubber bag 17 to abut against the inner top of the connecting hole 26, and the two ends of the top of the rubber bag 17 are respectively located inside and outside the insufflator body 1. When in use, the friction between the rubber bag 17 and the inner wall of the connecting hole 26 can better fix the position of the connecting plate 14. When the position of the connecting plate 14 is fixed, the position of the protective plate 2 will also be fixed to prevent the protective plate 2 from driving the connecting plate 14 and the lifting plate 22 to move during use. When in use, the rubber bag 17 can better fix the position of the protective plate 2 and the insufflator body 1. At the same time, the rubber bag 17 and the clamping plate 23 cooperate with each other to limit the up and down positions and left and right positions of the protective plate 2, the insufflator body 1 and the connecting plate 14, so that the insufflator body 1 is more stable when in use.

[0042] During use, a control valve is installed at one end of the delivery tube near the connecting block 28 to control the amount of carbon dioxide entering the delivery tube from the rubber bladder 17. When the amount of carbon dioxide inside the rubber bladder 17 is too high, the air pressure inside the rubber bladder 17 will become too high. At this time, the two ends of the rubber bladder 17 located inside and outside the insufflator body 1 will expand, increasing the space inside the rubber bladder 17 and reducing the air pressure inside the rubber bladder 17. The degree of expansion of the rubber bladder 17 allows people outside to understand the air pressure inside the rubber bladder 17 and control the amount of carbon dioxide delivered through the control panel of the insufflator body 1.

[0043] During use, the staff can push the movable plate 6 to move the movable plate 6 out of the mounting hole 5. The staff can hold the movable plate 6 and wipe the surface of the pneumoperitoneum machine body 1 with the brush 9 on the movable plate 6 to prevent dust from appearing on the surface of the pneumoperitoneum machine body 1. After wiping the surface of the pneumoperitoneum machine body 1, the staff can apply disinfectant on the brush 9 and wipe and disinfect the control panel of the pneumoperitoneum machine body 1 with the brush 9 to prevent the staff's hands from coming into contact with the control panel of the pneumoperitoneum machine body 1 when the staff needs to debug the pneumoperitoneum machine body 1 during surgery, causing dust and bacteria on the surface of the pneumoperitoneum machine body 1 to be contaminated on the staff's hands, and bacteria to come into contact with the patient's body when the staff performs surgery on the patient, so the patient can be better protected during use. When the control panel of the pneumoperitoneum machine body 1 is disinfected, the staff installs the movable plate 6 inside the mounting hole 5. When the staff needs to debug the pneumoperitoneum machine body 1 during the operation, the staff can push the movable plate 6 to make the movable plate 6 slide in the mounting hole 5. At the same time, the movable plate 6 drives the brush 9 thereon to disinfect the control panel of the pneumoperitoneum machine body 1. When the staff needs to debug the pneumoperitoneum machine body 1, the control panel can be disinfected multiple times at any time through the movable plate 6 and the brush 9.

[0044] During use, the staff can wind the delivery tube through the through hole 24 and install it on the clamping plate 23. When the staff needs to use the delivery tube, they can pick up the wound delivery tube according to the usage situation, so as to prevent the delivery tube from being too long during use and causing the delivery tube to come into contact with the ground, resulting in bacteria on the ground being contaminated on the delivery tube. When the staff uses the delivery tube, the bacteria on the delivery tube will come into contact with the patient through the staff's hands. At the same time, when in use, the staff can hook the end of the delivery tube away from the pneumoperitoneum machine body 1 into the through hole 24. The through hole 24 can store the air outlet end of the delivery tube for a short time, making it convenient for the staff to take the delivery tube for use.

[0045] When the insufflator body 1 is used, the staff disconnects the delivery tube from the connecting block 28 and pushes the protective plate 2 to move the protective plate 2 and the connecting plate 14 toward the insufflator body 1 until the connecting block 28 is located in the protective groove 27. When in use, the protective groove 27 can limit the moving distance of the protective plate 2. At the same time, the protective groove 27 can better protect the connecting block 28 to prevent external dust from falling into the inside of the connecting block 28 when the insufflator body 1 is stored.

[0046] The staff pulls the clip 10 on one side of the movable plate 6, which drives the shielding cloth 13 to move out of the placement hole 11, and inserts the two clips 10 into the two slots 8 respectively. The shielding cloth 13 can shield and protect the control panel of the insufflator body 1, and can prevent external dust from falling on the control panel when the insufflator body 1 is stored, and can better protect the control panel of the insufflator body 1. When the shielding cloth 13 protects the control panel of the insufflator body 1, because the brush 9 is in contact with the control panel of the insufflator body 1, the brush 9 can fix the position of the movable plate 6 and prevent the movable plate 6 from sliding in the mounting hole 5.

[0047] The staff pushes the lifting plate 22 so that the lifting plate 22 moves toward the rotating groove 18 through the slider 21. When the slider 21 is located on the side of the rotating groove 18, the staff rotates the lifting plate 22 so that the two lifting plates 22 are located on the top of the insufflator body 1, and the two clamping plates 23 abut against each other, and the through holes 24 on the two clamping plates 23 are connected to each other. The staff can insert their palms into the through holes 24 on the two clamping plates 23, and then lift the insufflator body 1 through the clamping plates 23 and the protective plate 2. When lifting the insufflator body 1, the two connecting plates 14 can better support the protective plate 2 and the lifting plate 22 through the connection with the connecting holes 26, so that the insufflator body 1 is more stable when lifted, and the staff can carry and store the insufflator body 1, which is more convenient to use.

[0048] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
