Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and specifically to a cardiovascular intubation nursing gripper. Background Art

[0002] During the process of performing heart or blood vessel surgery on a patient, it is generally necessary to use a gripper to intubate the cardiovascular system to meet the requirements of surgeries such as heart surgery and ensure the normal progress of the surgery.

[0003] However, the existing cardiovascular intubation nursing grippers still have the following problems:

[0004] In a new type of cardiovascular intubation gripper with the publication number CN211301676U, "including a first clamping rod and a second clamping rod that cross each other... the sliding column and the arc-shaped clamping block are driven by the push of the fastening threaded rod to fix and stabilize the intubation, facilitating the clamping work of intubations with different diameters". When using this gripper, it is necessary to rotate the fastening threaded rod on each of the two clamping arcs to drive the arc-shaped clamping block to move, so as to make it fit against the side of the intubation to achieve the clamping work of intubations with different diameters. However, in the actual operation process of this gripper, it is relatively inconvenient to use, the adjustment steps are relatively cumbersome, and generally, the gripper is manually clamped by medical staff. After long-term operation, the hand is prone to shaking and other situations, resulting in fluctuations in the clamping force, which will cause the intubation to fall off, and further affect the normal progress of the cardiovascular intubation operation.

[0005] Therefore, we propose a cardiovascular intubation nursing gripper to solve the problems raised above. Summary of the Invention

[0006] The purpose of the present invention is to provide a cardiovascular intubation nursing gripper to solve the problems in the above background art that the existing cardiovascular intubation nursing grippers on the current market are relatively inconvenient to operate when clamping intubations with different diameters, and are easily affected by the state of medical staff, resulting in the situation of falling off, which affects the normal progress of the intubation operation.

[0007] To achieve the above purpose, the present invention provides the following technical solution: A cardiovascular intubation nursing gripper, including a first clamping rod and a second clamping rod, the middle parts of the first clamping rod and the second clamping rod are connected by a movable shaft, and through holes into which fingers can extend are opened at the right ends of both the first clamping rod and the second clamping rod;

[0008] Two clamping arcs, which are respectively installed at the left ends of the first clamping rod and the second clamping rod, and the two clamping arcs are arranged to form a ring and can be sleeved outside the cardiovascular intubation;

[0009] It further includes:

[0010] A fixed seat is fixedly installed at the upper end of the first clamping rod. A threaded rod is installed on the right side of the fixed seat by means of a bearing, and a rotating block is connected to the right end of the threaded rod. Medical staff can drive the threaded rod to rotate through the rotating block;

[0011] The first driving rod and the second driving rod are respectively disposed in the first clamping rod and the second clamping rod in a fitting manner, and the first driving rod and the second driving rod are connected by a connecting component;

[0012] Two communicating plates are respectively fixedly installed in the first clamping rod and the second clamping rod;

[0013] Two cross bars are respectively engaged and slidably disposed in the first clamping rod and the second clamping rod, and positioning plates and piston plates are respectively installed at the left and right ends of the cross bars.

[0014] Preferably, the first driving rod is threadedly sleeved on the outside of the threaded rod, and the length of the transverse cross-section of the first driving rod is smaller than the length of the transverse cross-section of the second driving rod. When the rotating block drives the threaded rod to rotate, the first driving rod can be driven to move, and the connecting block installed on the second driving rod can be moved to the outside of the first driving rod, so as to realize the rotation between the first clamping rod and the second clamping rod, so as to place the cannula between the two clamping arcs.

[0015] Preferably, the connecting component is composed of a fixing plate, an H-shaped plate, a linkage block and an anti-detachment block. The fixing plate is located outside the second driving rod, and an H-shaped plate is installed on the front side of the fixing plate. Four linkage blocks are installed on the side of the H-shaped plate. The two upper linkage blocks are respectively disposed in the inner sides of the two sides of the first driving rod in a fitting manner, and the two lower linkage blocks are respectively disposed in the inner sides of the two sides of the second driving rod in a fitting manner, so that the first driving rod and the second driving rod can be connected under the action of the four linkage blocks, that is, the fixing effect between the first clamping rod and the second clamping rod is realized, so as to prevent the first clamping rod and the second clamping rod from rotating relative to each other under the influence of external force, and ensure the smooth progress of cannulation.

[0016] Preferably, two anti-detachment blocks with a trapezoidal cross-section are engaged and slidably disposed at the upper end of the second driving rod, and the two anti-detachment blocks are respectively installed at the lower parts of the two lower linkage blocks, so that under the action of the anti-detachment blocks, while the connecting component can slide on the second driving rod, the situation of falling off and being lost can be avoided.

[0017] Preferably, the left and right ends of the cross bar are connected to the positioning plate and the piston plate by a movable axis and a fixed connection respectively, and the positioning plate is arranged in an arc-shaped structure, and a silicone pad is installed on the right side of the positioning plate, so that the cross bar, the positioning plate and the piston plate can move synchronously, and the positioning plate can fix the cannula while reducing damage to the cannula during the movement.

[0018] Preferably, the piston plate is fitted to the inner wall of the cavity, and the cavities are respectively opened inside the first clamping rod and the second clamping rod, so that when the piston plate moves inside the cavity, air pressure can be formed on one side of the cavity.

[0019] Preferably, the side of the cavity and the suction cup are connected to each other through a hose, and the suction cup is installed on the inner left part of the clamping arc, so that when negative pressure is formed on one side of the cavity, the suction cup can fit tightly to the side of the cannula, thereby improving the clamping stability.

[0020] Preferably, a pressure spring is sleeved on the right side of the cross bar, and the right end of the pressure spring is fixed to the left side of the piston plate, and the left ends of the upper and lower pressure springs are respectively fixed inside the first clamping rod and the second clamping rod, so that after the cross bar is not affected by external force, it can be moved in the opposite direction and reset under the action of the pressure spring so that it can be used again.

[0021] Preferably, the connecting plate is located inside the through slot, and the through slot is opened through the inside of the cross bar, and the upper and lower cross bars are respectively connected to the first drive rod and the second drive rod through the connecting plate with a pull rope, so that when the first drive rod and the second drive rod are moved, the pull rope can be used to drive the corresponding cross bars to perform displacement activities.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: the cardiovascular cannula nursing clamp is provided with a connecting assembly and a positioning plate, so that after the first driving rod and the second driving rod are synchronously displaced through the connecting assembly, they can respectively drive the corresponding positioning plates to fix the cannula, and the suction cup improves the fixing effect. At the same time, under the action of the connecting assembly, the first clamping rod and the second clamping rod are prevented from rotating relative to each other due to external force, thereby preventing the cannula from falling due to hand tremors of medical staff. The specific effects are as follows:

[0023] 1. A positioning plate and a suction cup are provided. After the cannula is placed between the two clamping arcs, the first driving rod and the second driving rod can achieve synchronous left - right displacement under the action of the connecting component and the threaded rod. When moving synchronously to the right, the two positioning plates can be driven by the pull ropes to move towards the side of the cannula respectively, realizing the limiting effect on the cannula, and driving the piston plate to move leftward inside the cavity, causing a negative pressure to form inside the cavity. Since the cavity and the suction cup are interconnected, the suction cup can closely adhere to the outside of the cannula, improving the clamping stability of the cannula.

[0024] 2. An H - shaped plate and a linkage block are provided, enabling the connecting component to move inside the second driving rod, causing the two linkage blocks installed above the H - shaped plate to extend into the first driving rod. Since the first driving rod and the second driving rod are respectively installed inside the first clamping rod and the second clamping rod, the first clamping rod and the second clamping rod cannot rotate relative to each other under the action of external forces, thus avoiding the situation where the cannula falls out of the first driving rod and the second driving rod when the medical staff shakes due to long - term holding.

[0025] 3. An anti - detachment block and a fixing plate are provided. With the trapezoid - cross - section anti - detachment block, the connecting component can be movably arranged inside the upper end of the second driving rod, preventing the loss of the connecting component. At the same time, under the action of the fixing plate, it is convenient to pull the connecting component to move on the second driving rod, improving the convenience.

[0035] Please refer to Figures 1-7 , the present invention provides a technical solution: a cardiovascular intubation nursing clamp, including a first clamping rod 1 and a second clamping rod 2.

The fixed plate 801 is located outside the second driving rod 9, and an H-shaped plate 802 is installed on the front side of the fixed plate 801, and four linking blocks 803 are installed on the side of the H-shaped plate 802. The two linking blocks 803 located above are attached to the inside of both sides of the first driving rod 7, and the two linking blocks 803 located below are attached to the inside of both sides of the second driving rod 9; combined with Figures 1-4As shown, the medical staff first inserts their fingers into the through holes opened at the right ends of the first clamping rod 1 and the second clamping rod 2 respectively, driving the first clamping rod 1 and the second clamping rod 2 to rotate relative to each other, and then places the cannula between the two clamping arcs 3, and then pushes the connecting component 8 on the second driving rod 9 to cause the connecting component 8 to extend into the interior of the first driving rod 7, thereby realizing the connection between the first driving rod 7 and the second driving rod 9, that is, realizing the connection between the first clamping rod 1 and the second clamping rod 2, thereby preventing the first clamping rod 1 and the second clamping rod 2 from rotating again due to external force, thereby preventing the medical staff from If the hand tremors of the personnel cause the cannula to fall, the rotating block 6 is then rotated on the fixing seat 4, driving the connected threaded rod 5 to rotate synchronously. When the threaded rod 5 rotates, the first driving rod 7 sleeved on the outside of the threaded rod 5 can move to the right under the action of the first clamping rod 1, and the connecting assembly 8 is used to drive the second driving rod 9 to move synchronously; the upper end of the second driving rod 9 is engaged and slidably provided with two anti-falling blocks 804 with a trapezoidal cross-section, and the two anti-falling blocks 804 are respectively installed at the lower parts of the two linkage blocks 803 located below; combined with Figures 2-4 As shown, under the action of the anti-drop block 804, the connection assembly 8 can be prevented from falling or being lost on the second driving rod 9, thereby extending the service life;

[0036] The two cross bars 11 are respectively engaged and slidably arranged inside the first clamping rod 1 and the second clamping rod 2, and the left and right ends of the cross bar 11 are respectively installed with a positioning plate 12 and a piston plate 13; the left and right ends of the cross bar 11 are respectively connected to the positioning plate 12 and the piston plate 13 with a movable shaft, and the positioning plate 12 is an arc structure, and a silicone pad is installed on the right side of the positioning plate 12; a pressure spring 16 is sleeved on the right side of the cross bar 11, and the right end of the pressure spring 16 is fixed to the left side of the piston plate 13, and the left ends of the upper and lower pressure springs 16 are respectively fixed to the inside of the first clamping rod 1 and the second clamping rod 2; the connecting plate 17 is located inside the through groove 18, and the through groove 18 is opened inside the cross bar 11, and the upper and lower cross bars 11 are respectively connected to the first driving rod 7 and the second driving rod 9 by the connecting plate 17. A pull rope 19 is connected; the two connecting plates 17 are respectively fixedly installed inside the first clamping rod 1 and the second clamping rod 2; combined Figures 1-2 and Figures 5-7 As shown, after the first drive rod 7 and the second drive rod 9 are moved, the corresponding cross rod 11 can be driven to move by the pull rope 19, that is, the positioning plate 12 and the piston plate 13 can be driven to move synchronously. When the positioning plate 12 moves, the cannula can be fixed and limited. When the first drive rod 7 and the second drive rod 9 are moved in the opposite direction, the cross rod 11 can be reset by the pressure spring 16 to be used again.

[0037] The piston plate 13 fits against the inner wall of the cavity 14, and the cavity 14 is respectively formed inside the first clamping rod 1 and the second clamping rod 2; the side of the cavity 14 is interconnected with the suction cup 10 through a hose 15, and the suction cup 10 is installed on the inner left part of the clamping arc 3; combined with Figure 1 and Figures 5-6 as shown, when the piston plate 13 moves inside the cavity 14, it can cause the cavity 14 to form a negative pressure. Since the cavity 14 is interconnected with the suction cup 10, the suction cup 10 can closely fit against the outside of the cannula, thereby enhancing the fixing effect and ensuring the smooth progress of cardiovascular cannulation.

[0038] Working principle: When using this cardiovascular cannula nursing clamp, combined with Figures 1-7 as shown, medical staff first insert their fingers into the through holes formed at the right ends of the first clamping rod 1 and the second clamping rod 2 respectively, drive the first clamping rod 1 and the second clamping rod 2 to rotate relatively, then place the cannula between the two clamping arcs 3, rotate the first clamping rod 1 and the second clamping rod 2 in the reverse direction, then push the connecting component 8 into the inside of the first driving rod 7, and then rotate the rotating block 6. The connecting component 8 is used to drive the first driving rod 7 and the second driving rod 9 to move synchronously, so that the positioning plate 12 can achieve the limiting and fixing effect on the cannula, and the fixing effect is enhanced by using the suction cup 10. And under the action of the connecting component 8, the first clamping rod 1 and the second clamping rod 2 can be prevented from rotating under external force, thereby avoiding the situation that the cannula drops due to the shaking of the medical staff's hands and ensuring the smooth progress of cardiovascular cannulation.
