Description

Technical Field

[0001] The invention relates to the field of surgical operations, in particular to a clinical stone removal device for hepatobiliary surgery. Background Art

[0002] The reason for hepatobiliary surgery to remove stones is that bile duct stones may cause obstruction of bile flow, causing symptoms such as pain, jaundice, fever, and in severe cases, complications such as bile duct infection and pancreatitis, and even endanger life. Surgery to remove stones can restore the patency of the bile duct, eliminate symptoms, prevent complications, protect liver function, and improve the patient's quality of life. Therefore, for patients with bile duct stones, timely surgical stone removal is a necessary treatment measure.

[0003] The existing hepatobiliary stone removal devices mainly rely on two methods: mechanical clamping and negative pressure suction. During the operation, the mechanical clamping method is likely to cause physical damage to the bile duct wall and its surrounding tissues due to direct contact and clamping of the stones. As for the negative pressure suction method, since the stones are irregular in shape and size, and may be accompanied by impurities such as bile and blood, these substances are likely to accumulate in the pipe during the negative pressure suction process, causing blockage. Therefore, whether it is mechanical clamping or negative pressure suction, it is necessary to strictly control the force and negative pressure during the operation to reduce potential damage to the bile duct and its surrounding tissues. For this reason, we propose a hepatobiliary surgical clinical stone removal device. Summary of the invention

[0038] Compared with the prior art, the present invention has the following beneficial effects:

[0039] 1. By setting a collecting head, aligning the collecting head with the broken gravel, and then starting the first air pump, the first air pump evacuates the first collecting circle, the second collecting circle and the third collecting circle through the first air pipe, and the first collecting circle, the second collecting circle and the third collecting circle are contracted and folded under the support of two circle bodies and one telescopic circle and the auxiliary action of multiple first folding rods and second folding rods, and the third collecting circle is closed by the contraction of the telescopic circle. The entire first collecting circle, the second collecting circle and the third collecting circle are in a swirling state, and the gravel can be moved into the collecting head by suction, and then moved into the tube body by contraction action and the guidance of multiple guide rods. Since the first collecting circle, the second collecting circle and the third collecting circle are all made of medical rubber material and the gravel is collected by contraction and swirling, it will not cause soft tissue contusion in the body.

[0040] 2. By setting up the collecting head, start multiple electric push rods. The electric push rods at the corresponding parts remain stationary as needed, while the electric push rods at the other parts push the two rings and the telescopic ring to move accordingly. Since the electric push rods at the corresponding parts remain stationary, the entire first collecting ring, the second collecting ring and the third collecting ring will bend and shift to one side during the process of being evacuated. At this time, the gravel in the corner can be collected.

[0041] 3. By setting up a pushing component, the crushed stone is moved into the receiving head through suction, and then moved into the tube body through the contraction action and the guidance of multiple guide rods. At the same time, two driving parts are started to drive the two sets of moving rods to move back and forth alternately. When the two sets of moving rods move back and forth, they will synchronously drive the two sets of gears to mesh with the toothed plates, and then drive the two sets of pushing plates to rotate accordingly. At this time, since the surfaces of the two sets of pushing plates are set as arc-shaped transitions, the width of one end is greater than the other end, so when the two sets of pushing plates are driven to rotate back and forth, they will push the crushed stone to move in turn. Since the two sets of pushing plates move alternately, the crushed stone can be steadily and alternately pushed out of the tube body, which is not easy to cause blockage.

[0042] 4. By setting up a pushing component, when a group of pushing plates are driven to reciprocate and rotate at the same time, they will rotate at the same angle on both sides. However, due to the shape of the pushing plate, the width of one end is greater than that of the other end, and the angle at which the pushing plate is rotated is actually greater on one side than on the other side. Therefore, when the gravel is pushed, it will be pushed to the end of the tube body. Similarly, the air bag of the pushing plate is inflated so that the width ratio of the pushing plate is in the opposite state. At this time, the medicine is put into the end of the tube body, and the medicine is pushed to the front end of the tube body, and the medicine can be sent into the bile duct in the reverse direction.

[0043] 5. By setting a driving member and starting the motor, the motor drives the rotating wheel to rotate, which in turn drives the first connecting rod to rotate, and then drives the second connecting rod to perform linear reciprocating motion under the limit of the limit plate, that is, the pushing component can be driven to reciprocate. In addition, the hydraulic rod is started, and the hydraulic rod drives the connecting end of the first connecting rod to translate in the limit frame, so as to control the driving stroke of the driving member. During the pushing process of the crushed stone, it is squeezed alternately by the pushing plates on both sides, and the crushed stone will be further crushed. By changing the stroke of the driving member, the reciprocating distance of the moving rod is changed, so as to adjust the rotation angle of the pushing plate, so as to achieve the purpose of adjusting the size of the crushed stone.

[0052] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] See also Figure 1-7 In an embodiment of the present invention, a clinical stone removal device for hepatobiliary surgery includes a tube body 1, a receiving head 3 and a pushing assembly 4. One end of the tube body 1 is fixedly connected to a box body 2, and the other end of the tube body 1 is opened; a storage box 5 is slidably connected in the box body 2, and the storage box 5 is connected to the box body 2. The gravel is pushed out of the tube body 1 and then stored in the storage box 5. It should be noted that the storage box 5 can slide out of the box body 2 to facilitate the placement of medicines. After the box body 2 and the storage box 5 are combined, they are in a sealed state to ensure the pressure balance in the tube body 1; the device can be moved by the receiving head 3 to collect the gravel, and then the gravel is alternately pushed out of the tube body 1 through the pushing assembly 4.

[0054] Embodiment 1

[0055] like Figure 1 and Figure 3 As shown, in this embodiment, the receiving head 3 includes: a first receiving circle 31, a third receiving circle 32, a first folding rod 33, a second folding rod 34, an electric push rod 35 and a guide rod 36. One side of the first receiving circle 31 is fixedly connected to the second receiving circle 311, and the first receiving circle 31 and the second receiving circle 311 are both provided with a circle body 312; the third receiving circle 32 is fixedly connected to one side of the third receiving circle 32, and a telescopic circle 321 is provided in the third receiving circle 32. It should be noted that a damping mechanism is provided in the telescopic circle 321 to avoid repeated vibration. This is a prior art and will not be described in detail.

[0056] Multiple first folding rods 33 are rotatably connected between the first receiving circle 31 and the second receiving circle 311; multiple second folding rods 34 are rotatably connected between the second receiving circle 311 and the third receiving circle 32; multiple electric push rods 35 are fixedly connected to one end of the tube body 1, and the driving ends of multiple electric push rods 35 are rotatably connected to one side of the telescopic circle 321; multiple guide rods 36 are fixedly connected to the inner side of the third receiving circle 32, and the inner ends of multiple guide rods 36 extend into the tube body 1. When the receiving head 3 is retracted as a whole, the multiple guide rods 36 will be synchronously driven to move into the tube body 1, so that the gravel can be synchronously driven into the tube body 1.

[0057] Specifically, the collecting head 3 is aimed at the broken gravel, and then the first air pump 38 is started. The first air pump 38 evacuates the first collecting circle 31, the second collecting circle 311 and the third collecting circle 32 through the first air pipe 37. The first collecting circle 31, the second collecting circle 311 and the third collecting circle 32 are contracted and folded under the support of the two circle bodies 312 and the one telescopic circle 321 and the auxiliary action of the first folding rods 33 and the second folding rods 34. The third collecting circle 32 is closed by the contraction of the telescopic circle 321. The entire first collecting circle 31, the second collecting circle 311 and the third collecting circle 32 are in a twitching state, and the gravel can be moved into the collecting head 3 by suction, and then moved into the tube body 1 by the contraction action and the guidance of the multiple guide rods 36. It should be noted that the twitching refers to the wave-like contraction movement, which is similar to the contraction movement of the mouth muscles.

[0058] In this embodiment, a plurality of electric push rods 35 are started. As needed, the electric push rods 35 at corresponding positions remain stationary, while the electric push rods 35 at other positions push the two ring bodies 312 and the telescopic ring 321 to perform corresponding telescopic movements. Since the electric push rods 35 at corresponding positions remain stationary, the entire first collecting ring 31, the second collecting ring 311 and the third collecting ring 32 will bend and shift to one side during the process of being evacuated. At this time, the gravel in the corner can be collected.

[0059] like Figure 1 and Figure 3 As shown, further, the first collecting circle 31, the second collecting circle 311 and the third collecting circle 32 are connected, and a first air pipe 37 is fixedly connected to the tube body 1. One end of the first air pipe 37 extends into the first collecting circle 31, and the other end thereof passes through the tube body 1 and is fixedly connected to a first air pump 38. The first air pump 38 is fixedly connected to the outside of the box body 2. Since the first collecting circle 31, the second collecting circle 311 and the third collecting circle 32 are connected, the air suction will drive the collecting head 3 to shrink as a whole.

[0060] Furthermore, the first collecting ring 31, the second collecting ring 311 and the third collecting ring 32 are all made of rubber material. The first collecting ring 31 and the second collecting ring 311 have the same size, and the third collecting ring 32 is smaller than the first collecting ring 31 and the second collecting ring 311. One side of the third collecting ring 32 is closed and is made of medical rubber material that does not react with body fluids and drugs. Since one side of the third collecting ring 32 is closed, it can be further closed by the telescopic ring 321, so that the gravel can be easily put into the collecting head 3.

[0061] Embodiment 2

[0062] On the basis of the first embodiment, in order to push the gravel, a pushing component 4 is provided.

[0063] like Figure 1-7 As shown, in this embodiment, the pushing assembly 4 includes: a pad 41, a moving rod 42, a rotating shaft 43, a tooth plate 44, a pushing plate 45, a connecting pipe 46, a connecting rod 47 and a driving member 48. The two pads 41 are fixedly connected in the tube body 1, and the two pads 41 are arranged opposite to each other; the two moving rods 42 are slidably connected to the pads 41; the multiple rotating shafts 43 are rotatably connected between the two moving rods 42, and the multiple rotating shafts 43 are fixedly sleeved with two gears 431; the two tooth plates 44 are fixedly connected to the pad 41, and the two tooth plates 44 are respectively meshed with the multiple gears 431; the multiple pushing plates 45 are fixedly sleeved on the outside of the rotating shaft 43. , every two gears 431 are respectively arranged on both sides of a plurality of pushing plates 45, and an airbag 451 is fixedly connected to the pushing plate 45; a plurality of connecting tubes 46 are fixedly connected to the airbag 451, and the plurality of connecting tubes 46 are connected to each other, one end of the last connecting tube 46 is fixedly connected to a second air pipe 461, and a second air pump 462 is fixedly connected to the outer side of the box body 2, and the second air pipe 461 is connected to the second air pump 462; a connecting rod 47 is fixedly connected to the ends of the two moving rods 42; a driving member 48 is fixedly arranged in the box body 2, and a driving end of the driving member 48 is fixedly connected to the connecting rod 47, and the driving member 48 drives the moving rod 42 to perform reciprocating linear movement.

[0064] During specific implementation, the crushed stones are moved into the receiving head 3 by suction, and then moved into the tube body 1 by the contraction action and the guidance of the multiple guide rods 36. At the same time, the two driving members 48 are started to drive the two groups of moving rods 42 to move back and forth alternately. When the two groups of moving rods 42 move back and forth, they will synchronously drive the two groups of gears 431 to mesh with the toothed plates 44, and then drive the two groups of pushing plates 45 to rotate accordingly. At this time, since the surfaces of the two groups of pushing plates 45 are set as arc-shaped transitions, and the width of one end is greater than the other end, the two groups of pushing plates 45 will push the crushed stones to move in turn when they are driven to rotate back and forth. Since the two groups of pushing plates 45 move alternately, the crushed stones can be pushed out of the tube body 1 alternately.

[0065] It should be noted that when a set of pushing plates 45 are driven to reciprocate and rotate at the same time, they will rotate at the same angle on both sides. However, due to the shape of the pushing plate 45, the width of one end is greater than the other end, and the angle of rotation of the pushing plate 45 is actually greater than that of the other side. Therefore, when the gravel is pushed, it will be pushed to the end of the tube body 1. Similarly, the air bag 451 of the pushing plate 45 is inflated, so that the width ratio of the pushing plate 45 is in the opposite state. At this time, the medicine is put into the end of the tube body 1, and the medicine is pushed to the front end of the tube body 1, and the medicine can be sent into the bile duct in the reverse direction. In this embodiment, Figure 6 This is a schematic diagram of pushing gravel by the pushing component 4. Figure 7 It is a schematic diagram of the pushing component 4 pushing medicine.

[0066] In the present invention, in order to facilitate the operator to control the present invention, a driving member 48 is provided.

[0067] like Figure 5 As shown, the driving member 48 includes: a motor 481, a limit frame 482, a hydraulic rod 483, and a limit plate 485. The motor 481 is fixedly connected to the inner side of the box body 2, and the driving end of the motor 481 is fixedly connected to the rotating wheel 4811; the limit frame 482 is fixedly connected to the rotating wheel 4811, and a first connecting rod 4821 is limited and slidable in the limit frame 482; the hydraulic rod 483 is fixedly connected to one end of the limit frame 482, and the driving end of the hydraulic rod 483 extends into the limit frame 482 and is fixedly connected to the rotating end of the first connecting rod 4821; the second connecting rod 484, the second connecting rod 484 is rotatably connected to one end of the first connecting rod 4821, and one end of the second connecting rod 484 is fixedly connected to the connecting rod 47; the limit plate 485 is fixedly connected to the inner side of the box body 2, and the second connecting rod 484 is slidably connected to the limit In the positioning plate 485, the motor 481 is started, and the motor 481 drives the rotating wheel 4811 to rotate, thereby driving the first connecting rod 4821 to rotate, and then driving the second connecting rod 484 to perform linear reciprocating motion under the limit of the limiting plate 485, that is, it can drive the pushing component 4 to reciprocate. In addition, the hydraulic rod 483 is started, and the hydraulic rod 483 drives the connecting end of the first connecting rod 4821 to translate in the limiting frame 482, so as to control the driving stroke of the driving member 48. In the process of pushing the crushed stone, it is alternately squeezed by the pushing plates 45 on both sides, and the crushed stone will be further crushed. By changing the stroke of the driving member 48, the reciprocating distance of the moving rod 42 is changed, so as to adjust the rotation angle of the pushing plate 45, so as to achieve the purpose of adjusting the size of the crushed stone.

[0068] The present invention also provides an operating method for a clinical stone removal device for hepatobiliary surgery, specifically, a rubber sleeve is covered on the outside of the pushing component 4 in the tube body 1. Since the rubber sleeve has great toughness and fits with the pushing plate 45 of the pushing component 4, the rubber sleeve is simultaneously telescoped and folded during the pushing process of the pushing plate 45. This can prevent gravel from entering the gap of the pushing component 4 and causing jamming. In addition, each mechanism in the pushing component 4 has been treated with rust and corrosion prevention.

[0069] Working principle: first, put the tube body 1 into the bile duct of the liver and gallbladder, and then implement stone removal, specifically: first, aim the collection head 3 at the broken stones, and then start the first air pump 38, the first air pump 38 pumps air to the first collection circle 31, the second collection circle 311 and the third collection circle 32 through the first air pipe 37, the first collection circle 31, the second collection circle 311 and the third collection circle 32 are supported by two circle bodies 312 and a telescopic circle 321 and assisted by multiple first folding rods 33 and second folding rods 34, and the third collection circle 32 is closed by the contraction of the telescopic circle 321, and the entire first collection circle 31, the second collection circle 311 and the third collection circle 32 are in a hesitant state, which can remove the broken stones. The stones are moved into the receiving head 3 by suction, and then moved into the tube body 1 by the contraction action and the guidance of multiple guide rods 36. At the same time, the two driving members 48 are started to drive the two groups of moving rods 42 to move back and forth alternately. When the two groups of moving rods 42 move back and forth, they will synchronously drive the two groups of gears 431 to mesh with the toothed plate 44, and then drive the two groups of pushing plates 45 to rotate accordingly. At this time, since the surfaces of the two groups of pushing plates 45 are arranged in an arc-shaped transition, and the width of one end is greater than the other end, the two groups of pushing plates 45 will push the gravel to move in turn when they are driven to rotate back and forth. Since the two groups of pushing plates 45 move alternately, the gravel can be pushed out of the tube body 1 alternately, and then fall into the storage box 5, and cleaned after it is full.
