Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to an integrated negative pressure gripping suction device. Background Technology
[0002] Robot-assisted laparoscopic surgery is a minimally invasive procedure often used to treat various lesions within the abdominal cavity. During laparoscopy, staff use auxiliary tools to remove tissues from the body to achieve the surgical goal.
[0003] Regarding the aforementioned technologies, the inventors believe that the following defects exist: When encountering large tissues such as fat or blood clots during surgery, the laparoscopic technology in the prior art has limited removal effectiveness, is difficult to remove, and requires frequent replacement of other auxiliary tools, thus increasing the limitations of the device. Utility Model Content
[0004] To solve the above problems, this utility model provides an integrated negative pressure gripping suction device.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an integrated negative pressure gripping suction device, including an internally hollow mounting rod, one end of which is rotatably provided with two clamps, a handheld part is installed at the end of the mounting rod away from the clamps, a negative pressure connection port is provided at the end of the handheld part away from the mounting rod, the negative pressure connection port, the handheld part and the mounting rod are interconnected, a baffle plate is installed inside the handheld part, and a control component for controlling the opening and closing of the clamps is provided on the handheld part.
[0006] By adopting the above technical solution, when medical staff perform surgery, they insert clamps into the body by holding the handle. During this process, they can rotate the clamps to grasp objects. When blood clots or fat are found inside the body, the medical staff activates the control component to rotate the clamps, thereby breaking them up. Subsequently, the medical staff connects to a negative pressure tube through the negative pressure connection port to suction out the broken blood clots and fat. This process reduces the difficulty of the medical staff's work. In addition, medical staff can complete many tasks with this device without frequently changing tools during the operation, thus reducing the limitations of the device.
[0007] Furthermore, a first sliding groove is provided through the handgrip. The control assembly includes two fixed rods respectively fixed in the two clamps, two rotating rods respectively rotatably mounted on the outer walls of the two fixed rods, a first sliding rod slidably mounted in the first sliding groove, a rotating shaft rotatably mounted on the end of the two rotating rods away from the fixed rods, a first roller fixed on the inner wall of the handgrip, and a first traction rope fixed on the side wall of the first sliding rod. The other end of the first traction rope passes around the first roller and is fixed to the rotating shaft. The clamps are rotatably connected to the mounting rod.
[0008] By adopting the above technical solution, when medical staff need to rotate the clamp, they press down on the first sliding rod, causing it to slide downwards. This moves the first traction rope downwards under the action of the first sliding rod, which in turn drives the first roller to rotate. This causes the other end of the first traction rope to move closer to the first roller, which in turn moves the rotating shaft closer to the first roller under the action of the first traction rope. This causes the rotating rod to rotate under the action of the rotating shaft, thus clamping the clamp. In this process, the difficulty for medical staff to rotate the clamp is reduced, thereby reducing the workload of medical staff.
[0009] Furthermore, each of the two clamps has a receiving groove on its inner wall, and a magnetic piece is installed in each of the two receiving grooves. The two magnetic pieces repel each other.
[0010] By adopting the above technical solution, when medical staff slide the first slide bar upward, the clamps rotate in a direction away from each other under the action of the two magnetic plates, thereby opening the clamps. During this process, the control components are reset under the action of the clamps, so that medical staff can reuse the main body of the device, thereby improving the practicality of the device.
[0011] Furthermore, a second sliding groove is provided through the handle, and a rotating groove is provided on the inner wall of the handle. A second sliding rod is slidably arranged in the second sliding groove, and a rotating rod is rotatably arranged in the rotating groove. The rotating rod is fixed to the blocking plate. A second roller is fixedly arranged on the inner wall of the handle, and a second traction rope is fixedly arranged on the side wall of the second sliding rod. The other end of the second traction rope passes around the second roller and is fixed to the blocking plate.
[0012] By adopting the above technical solution, when medical staff need to clean up broken blood clots and fat, they need to slide the second slide bar downwards, which in turn causes the second traction rope to move downwards under the action of the second slide bar. This causes the second traction rope to drive the second roller to rotate, which in turn causes the baffle plate to rotate under the action of the second traction rope. This causes the rotating rod to rotate with the baffle plate. During this process, the baffle plate stops obstructing the internal space of the handpiece, allowing the broken blood clots and fat to be sucked out of the body by negative pressure. This process reduces the difficulty for medical staff to frequently connect negative pressure pipes, thereby reducing the workload of medical staff.
[0013] Furthermore, a reset groove is provided on the inner wall of the rotating groove, and a torsion spring is fixedly provided on the inner wall of the reset groove. The other end of the torsion spring is fixedly provided on the side wall of the rotating rod away from the blocking plate.
[0014] By adopting the above technical solution, when medical staff slide the second slide bar upward, the rotating rod rotates in the opposite direction under the action of the torsion spring, which in turn causes the blocking plate to rotate in the opposite direction under the action of the rotating rod, thereby resetting the group of blocking plates and causing the blocking plate to block the space inside the handpiece again, thus reducing the probability of medical staff working under negative pressure continuously during the operation.
[0015] Furthermore, a water inlet is provided through the side wall of the handheld part.
[0016] By adopting the above technical solution, the water inlet reduces the difficulty for medical staff to clean the inside of the device, thereby reducing the difficulty of their work.
[0017] Furthermore, a valve is installed inside the water inlet.
[0018] By adopting the above technical solution, the valve reduces the difficulty for medical staff to open and close the water inlet, thereby reducing the workload of medical staff.
[0019] In summary, this utility model has the following beneficial effects:
[0020] 1. In this application, when medical personnel perform surgery, they insert clamps into the body by holding the handle. During this process, they can rotate the clamps to grasp objects. If blood clots or fat are found inside the body, the medical personnel activate the control component to control the clamp rotation, thereby breaking up the blood clots and fat. Subsequently, the medical personnel connect a negative pressure tube through the negative pressure connection port to suction out the broken blood clots and fat. This process reduces the difficulty of the medical personnel's work. Furthermore, medical personnel can complete many tasks using this device without frequently changing tools during the procedure, thus reducing the limitations of the device.
[0021] 2. In this application, when medical staff need to rotate the clamp, they press down on the first sliding rod, causing it to slide downwards. This causes the first traction rope to move downwards under the action of the first sliding rod, which in turn drives the first roller to rotate. This causes the other end of the first traction rope to move closer to the first roller, which in turn causes the rotating shaft to move closer to the first roller under the action of the first traction rope. This causes the rotating rod to rotate under the action of the rotating shaft, thereby clamping the clamp. In this process, the difficulty for medical staff to rotate the clamp is reduced, thus reducing the workload of medical staff.
[0022] 3. In this application, when medical staff slide the first slide bar upward, the clamps rotate in a direction away from each other under the action of the two magnetic plates, thereby opening the clamps. During this process, the control component is reset under the action of the clamps, so that medical staff can reuse the main body of the device, thereby improving the practicality of the device.

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0030] like Figure 1-5 As shown in the illustration, this application discloses an integrated negative pressure gripping suction device, including a mounting rod 1, clamps 11, a handheld part 12, a negative pressure connection port 13, a baffle plate 14, a control component 3, a magnet 4, a second sliding rod 5, a rotating rod 51, a second roller 52, a second traction rope 53, and a torsion spring 6. The mounting rod 1 is a hollow, round rod-shaped structure with a horizontal axis. Two clamps 11 are rotatably mounted on one end of the rotating rod 32. The handheld part 12 is hollow and mounted on the end of the mounting rod 1 away from the clamps 11. The negative pressure connection port 13 is located on the end of the handheld part 12 away from the mounting rod 1, and the negative pressure connection port 13, the handheld part 12, and the mounting rod 1 are interconnected. The baffle plate is a round plate-shaped structure with its axis coinciding with the axis of the mounting rod 1, and is mounted inside the handheld part 12.
[0031] During surgery, medical staff insert clamps 11 into the body using the handle 12. During this process, they can rotate the clamps 11 to grasp objects. If blood clots or fat are found inside the body, the medical staff activates the control component 3 to control the rotation of the clamps 11, thereby breaking them up. Subsequently, the medical staff connects to a negative pressure tube through the negative pressure connection port 13 to suction out the broken blood clots and fat, reducing the difficulty of the medical staff's work. Furthermore, this device allows medical staff to perform many tasks without frequently changing tools during surgery, thus reducing the device's limitations.
[0032] A first sliding groove 2 is provided through the handle 12. A control component 3 is disposed on the handle 12 and is used to control the opening and closing of the clamps 11. The control component 3 includes a fixed rod 31, a rotating rod 32, a first sliding rod 33, a rotating shaft 34, a first roller 35, and a first traction rope 36. The fixed rod 31 is a round rod structure with a horizontal axis. Two fixed rods 31 are provided and fixedly disposed in the two clamps 11 respectively. Two rotating rods 32 are provided and rotatably disposed on the outer wall of the two fixed rods 31 respectively. The first sliding rod 33 is a rectangular rod structure and slides within the first sliding groove 2. The rotating shaft 34 is a round rod structure with a horizontal axis and is rotatably disposed at the end of the two rotating rods 32 away from the fixed rod 31. The first roller 35 is fixedly mounted on the inner wall of the hand-held part 12. One end of the first traction rope 36 is fixedly mounted on the side wall of the first slide bar 33. The other end of the first traction rope 36 passes around the first roller 35 and is fixed to the rotating shaft 34. The clamp 11 is rotatably connected to the mounting rod 1.
[0033] When medical staff need to rotate clamp 11, they press down on the first sliding rod 33, causing it to slide downwards. This moves the first traction rope 36 downwards, which in turn drives the first roller 35 to rotate. The other end of the first traction rope 36 moves closer to the first roller 35, causing the rotating shaft 34 to move closer to the first roller 35. This causes the rotating rod 32 to rotate under the action of the rotating shaft 34, thus clamping clamp 11. This process reduces the difficulty for medical staff to rotate clamp 11, thereby reducing the workload of their work.
[0034] The inner walls of the two clamps 11 are provided with receiving grooves 21. Two magnet pieces 4 are provided and installed in the two receiving grooves 21 respectively, and the two magnet pieces 4 repel each other.
[0035] When medical staff slide the first slide bar 33 upwards, the clamp 11 rotates away from each other under the action of the two magnets 4, thereby opening the clamp 11. During this process, the control component 3 is reset under the action of the clamp 11, so that medical staff can reuse the main body of the device, thereby improving the practicality of the device.
[0036] A second sliding groove 22 is formed through the handle part 12, and a rotating groove 23 is formed on the inner wall of the handle part 12. The second sliding rod 5 is a rectangular rod structure and is slidably disposed in the second sliding groove 22. The rotating rod 51 is a round rod structure with its axis horizontal. The rotating rod 51 is rotatably disposed in the rotating groove and is fixed to the blocking plate 14. The second roller 52 is fixedly disposed on the inner wall of the handle part 12. One end of the second traction rope 53 is fixedly disposed on the side wall of the second sliding rod 5, and the other end of the second traction rope 53 passes around the second roller 52 and is fixed to the blocking plate 14.
[0037] When medical staff need to clean up broken blood clots and fat, they need to slide the second slide bar 5 downwards, which causes the second traction rope 53 to move downwards under the action of the second slide bar 5. This causes the second traction rope 53 to drive the second roller 52 to rotate, which in turn causes the baffle plate 14 to rotate under the action of the second traction rope 53. This causes the rotating rod 51 to rotate with the baffle plate 14. During this process, the baffle plate 14 stops obstructing the internal space of the handheld part 12, allowing the broken blood clots and fat to be sucked out of the body by negative pressure. This process reduces the difficulty for medical staff to frequently connect negative pressure pipes, thereby reducing the workload of medical staff.
[0038] A reset groove 24 is provided on the inner wall of the rotating groove 23. One end of the torsion spring 6 is fixedly set on the inner wall of the reset groove 24, and the other end of the torsion spring 6 is fixedly set on the side wall of the rotating rod 51 away from the blocking plate 14.
[0039] When medical staff slide the second slide bar 5 upwards, the rotating bar 51 rotates in the opposite direction under the action of the torsion spring 6, which in turn causes the blocking plate 14 to rotate in the opposite direction under the action of the rotating bar 51, thereby resetting the baffle and causing the blocking plate 14 to block the space inside the hand-held part 12 again, thus reducing the probability of medical staff working under negative pressure continuously during the operation.
[0040] To reduce the difficulty of the work for staff, a water inlet 7 is provided through the side wall of the handheld part 12. The water inlet 7 reduces the difficulty for medical staff to clean the inside of the main body of the device, thereby reducing the difficulty of the work for medical staff.
[0041] To reduce the workload for staff, a valve 8 is installed inside the water inlet 7. Valve 8 reduces the difficulty for medical staff to open and close the water inlet 7, thereby reducing the workload for medical staff.
[0042] The working principle of the integrated negative pressure gripping suction device in this embodiment is as follows: When medical staff perform surgery, they insert the clamps 11 into the body by holding the handle 12. During this process, the medical staff can rotate the clamps 11 to grasp the contents. If blood clots or fat are found inside the body, the medical staff activates the control component 3 to control the clamps 11 to rotate, thereby breaking up the blood clots and fat. Subsequently, the medical staff connects to the negative pressure tube through the negative pressure connection port 13 to suction out the broken blood clots and fat. This process reduces the difficulty of the medical staff's work. In addition, medical staff can complete many tasks with this device without frequently changing tools during the work process, thus reducing the limitations of the device.
[0043] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
