Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a clinical stone removal device for hepatobiliary surgery. Background Art

[0002] Hepatobiliary surgery mainly studies major diseases that seriously threaten the health of Chinese people, such as hepatocellular carcinoma, hepatobiliary stones, post-hepatitis cirrhosis and acute liver failure caused by severe hepatitis. Hepatobiliary stones are relatively common diseases in hepatobiliary surgery and are mostly treated by surgical operations. During the surgical stone removal process, lithotripsy forceps are usually required to remove the stones from the patient's body.

[0003] When using lithotripsy to remove stones, only one stone can be clamped at a time. After the stone is removed from the patient's body, if there are still stones in the patient's body, the lithotripsy needs to be extended into the patient's body to continue to remove the stones one by one. This may result in a low efficiency in removing the stones, and when the lithotripsy repeatedly enters and exits the patient's body, it may also cause secondary damage to the patient's wound. For this reason, we propose a clinical lithotripsy device for hepatobiliary surgery. Summary of the invention

When in use, the medical staff holds the first handle 11 and the second handle 12, and moves the lower side of the second handle 12 close to the first handle 11, so that the pillar 22 on the upper side of the second handle 12 pulls the pull rod 23 to move close to the second handle 12, so that the movable seat 24 moves in the direction close to the first handle 11, and the two clamping members 27 are moved close to each other through the first connecting rod 25 and the second connecting rod 26, so as to clamp the stone through the two clamping members 27.

[0038] A cylindrical member 28 is slidably provided on the outer side of the clamp rod 21, and a limiting groove 29 is symmetrically provided on the outer side of the clamp rod 21. The cylindrical member 28 slides along the limiting groove 29, and an anti-slip pad can be fixed on the inner side of the cylindrical member 28. The cylindrical member 28 will not move without being pushed by external artificial force. A ring block 210 is threadedly provided on one side of the cylindrical member 28, and two protrusions are provided on one side of the cylindrical member 28. The ring block 210 is threadedly provided between the two protrusions on one side of the cylindrical member 28 to limit the position of the ring block 210.

[0039] A fourth connecting rod 214 is rotatably provided on the inner side of the inner support member 213 and is rotatably provided with the cylinder member 28. An L-shaped block 215 is fixedly provided on the inner side of one end of the inner support member 213. A rotating block 216 is rotatably provided on one side of the L-shaped block 215. A first protective cloth 219 is fixedly provided on the outer side of the plurality of inner support members 213. Both sides of the first protective cloth 219 are respectively fixedly provided with the annular member 211 and the plurality of L-shaped blocks 215. That is, the first protective cloth 219 is wrapped around the plurality of inner support members 213 and the outer side of the L-shaped block 215. The fixing of one side of the first protective cloth 219 with the annular member 211 can make the first protective cloth 219 between the inner support member 213 and the annular member 211 The position of the rotating block 216 is sealed to prevent the leakage of stones. A second protective cloth 220 is fixedly arranged on the outer side of the plurality of rotating blocks 216. The first protective cloth 219 and the second protective cloth 220 can be made of transparent material, so that medical staff can observe the collection of stones in the first protective cloth 219 and the second protective cloth 220, and can reduce the obstruction of vision that may be caused when clamping stones. The first protective cloth 219 and the second protective cloth 220 both have good elasticity and ductility to ensure the telescopic and expansion capabilities of the first protective cloth 219 and the second protective cloth 220. Initially, the first protective cloth 219 and the second protective cloth 220 are in a folded and contracted state;

[0040] Both sides of the rotating block 216 are fixed with connecting shafts 217 rotatably arranged with the L-shaped block 215, and the L-shaped block 215 is provided with a mounting cavity at the connecting shaft 217. Both sides of the rotating block 216 and the L-shaped block 215 are provided with torsion springs 218, which are sleeved on the outside of the connecting shaft 217. The torsion springs 218 and the connecting shaft 217 are located in the mounting cavity of the L-shaped block 215. Initially, under the elastic force of the torsion springs 218, one side of the rotating block 216 abuts against the outside of the clamp rod 21. Thus, the first protective cloth 219 and the second protective cloth 220 can form a closed space.

[0041] A sleeve member 221 is slidably provided on one side of the clamp rod 21 close to the first handle 11, and a guide groove 222 is symmetrically provided on the outer side of the clamp rod 21. The sleeve member 221 slides along the guide groove 222, and an anti-skid pad can be fixed on the inner side of the sleeve member 221. When not pushed by an external artificial force, the sleeve member 221 will not move. A connecting ring 223 is movably sleeved on the outer side of the sleeve member 221. Both ends of the sleeve member 221 are provided with protrusions. The connecting ring 223 is located between the protrusions at both ends of the sleeve member 221 to limit the moving range of the connecting ring 223. Support rods 224 are symmetrically fixed between the connecting ring 223 and the annular block 210. A pull rope 225 that movably passes through the inner support member 213 is fixed on one side of the plurality of rotating blocks 216. The pull rope 225 passes through the inside of the inner support member 213 and is fixed to the sleeve member 221.

[0042] After the stone is clamped by the two clamping members 27, the medical staff can rotate the connecting ring 223 and rotate the annular block 210 through the support rod 224, so that the annular block 210 can drive the annular member 211 to move close to the clamping member 27, and the annular block 210 can be moved to the raised position of the barrel member 28 close to the clamping member 27. The inner support member 213 can be expanded outward through the third connecting rod 212 and the fourth connecting rod 214, so that the first protective cloth 219 can be expanded outward, and then the sleeve member 221 can be moved away from the clamping member 27, and the pull rope 225 can be used to pull the sleeve member 221 away from the clamping member 27. , pull one end of the rotating block 216 to rotate toward the inner support member 213, and rotate it until it abuts against the inner side of the inner support member 213, so that when the stone is subsequently clamped and collected, it can prevent the stone collected on the inner side of the inner support member 213, the L-shaped block 215 and the first protective cloth 219 from leaking out from between the rotating block 216 and the inner support member 213 when the cylinder member 28 and the inner support member 213 move toward the clamping member 27, and it can also prevent the rotating block 216 from touching the clamping member 27 and the stone during the movement toward the clamping member 27, which may cause the stone to loosen after clamping. The sleeve member 221 makes the pull rope 225 pull the rotating block 216 to rotate until it contacts the inner support member 213, so that the connecting ring 223 contacts the protrusion of the sleeve member 221 close to the clamping member 27, and then pushes the connecting ring 223 to move close to the clamping member 27, thereby driving the sleeve member 221, the support rod 224, the annular block 210 and the cylinder member 28 to move close to the clamping member 27, and after the movement, the stone clamped by the clamping member 27 is located on the inner side of the first protective cloth 219, and the rotating block 216 is located on the side of the stone away from the first handle 11, and then close to the clamping member 27. The sleeve member 221 is moved to make the pull rope 225 in a relaxed state. Under the elastic force of the torsion spring 218, the multiple rotating blocks 216 are rotated away from the inner support member 213. The multiple rotating blocks 216 and the second protective cloth 220 can shield the side of the stone away from the first handle 11. Then, the first handle 11 and the second handle 12 are used to release the clamping of the two clamping members 27 on the stone, so that the stone falls into the first protective cloth 219. The shielding effect of the multiple rotating blocks 216 and the second protective cloth 220 can prevent the stone from leaking out from the side away from the first handle 11.

[0043] Then, the sleeve member 221 is moved away from the clamping member 27, and the rotating block 216 is pulled by the pull rope 225 to rotate until it abuts against the inner side of the inner support member 213, which can prevent the collected stones from leaking out during the reverse movement and reset, and can make the connecting ring 223 abut against the protrusion of the sleeve member 221 close to the clamping member 27. Then, the sleeve member 221 is pulled away from the clamping member 27, and the connecting ring 223, the support rod 224 and the cylinder member 28 are connected by the thread of the annular block 210 and the cylinder member 28, so that the connecting ring 223, the support rod 224 and the cylinder member 28 can be moved in the opposite direction and reset. After the movement and reset, the annular block 210 is rotated in the opposite direction so that the annular member 211 is in the cylinder The two protrusions of the body 28 are reversely moved and reset, so that the inner support member 213 is contracted inward to prevent the inner support member 213 and the first protective cloth 219 from expanding and blocking the stone when clamping, and then the sleeve member 221 is moved towards the clamping member 27, so that the protrusion of the sleeve member 221 away from the clamping member 27 is in contact with the connecting ring 223, and under the elastic force of the torsion spring 218, the rotating block 216 is pressed against the outer side of the clamp rod 21, and combined with the second protective cloth 220, the clamped stone can be collected and prevented from leaking. Similarly, the stone can continue to be clamped and collected in this way;

[0044] After the collected stones are taken out together, the clamp rod 21 can be inverted, that is, the clamping member 27 is located on the upper side, so that the collected stones are moved to the side of the first protective cloth 219 close to the annular block 210, and then the sleeve member 221 is moved away from the clamping member 27. By pulling the rope 225, the rotating block 216 is rotated until it is against the inner side of the inner support member 213, and then the clamp rod 21 is inverted back so that the clamping member 27 is located on the lower side, and the connecting ring 223 can be pushed to move the barrel member 28 close to the clamping member 27, so that the stones fall out of the first protective cloth 219 from between the multiple rotating blocks 216 under the action of gravity, so as to clean out the collected stones.

[0045] Embodiment 3

[0046] The stone crushing assembly 3 includes a connecting sleeve 31 fixed to the clamp rod 21, a mounting block 32 is slidably arranged inside the connecting sleeve 31, a slide groove 33 is symmetrically arranged inside the connecting sleeve 31, the mounting block 32 slides along the slide groove 33 to guide the movement of the mounting block 32, a stone crushing electrode 34 is fixed on one side of the mounting block 32, a first spring 35 is fixed between the mounting block 32 and the connecting sleeve 31, and a stopper 36 is fixed on the outer side of the stone crushing electrode 34;

[0047] A push rod 37 is slidably provided on one side of the cylinder member 28 close to the stopper 36, a sliding cavity is provided on the cylinder member 28 at the push rod 37, the push rod 37 slides along the sliding cavity of the cylinder member 28, a second spring 38 fixed to the cylinder member 28 is fixed on the side of the push rod 37 away from the stopper 36, the elastic strength of the second spring 38 is greater than the elastic strength of the first spring 35, and a button 39 electrically connected to the lithotripsy electrode 34 is installed on the side of the clamp rod 21 close to the pillar 22;

[0048] In the process of moving the barrel 28 close to the clamping member 27 so that the clamped stone is located in the first protective cloth 219, the push rod 37 can be made to collide with the stopper 36, and the push rod 37 can push the stopper 36 to move close to the stone clamped by the clamping member 27, so that the lithotripsy electrode 34 moves to the stone position, and the first spring 35 is stretched. For larger stones, after the lithotripsy electrode 34 moves to collide with the stone, the continued movement of the barrel 28 will not cause the push rod 37 to push the stopper 36 to move, so that the push rod 37 slides into the sliding cavity of the barrel 28, and the second spring 38 is compressed, so that for stones of different sizes, the lithotripsy electrode 34 can be moved to the stone position by the movement of the barrel 28. After the rotary block 216 moves to the side of the stone away from the first handle 11 and the rotating block 216 and the second protective cloth 220 form a shield for the side of the stone away from the first handle 11, the button 39 can be pressed to crush the larger stones through the lithotripsy electrode 34 to facilitate the collection of the stones in the first protective cloth 219. The shielding effect of the rotary block 216, the second protective cloth 220 and the first protective cloth 219 on the stones can prevent the stones from splashing outward when the lithotripsy electrode 34 crushes the stones, which is not conducive to the clamping and collection of the stones. When the cylinder part 28 moves back away from the clamping part 27 to reset, the lithotripsy electrode 34 and the push rod 37 can be reset under the elastic force of the first spring 35 and the second spring 38.

[0049] An L-shaped rod 310 is fixedly provided on one side of the pull rod 23 near the button 39, and a through groove 312 is penetrated through the clamp rod 21 at the L-shaped rod 310, and the L-shaped rod 310 slides along the through groove 312. A limiting hole 311 adapted to the L-shaped rod 310 is provided on the button 39, and the limiting hole 311 is provided through the button 39. When the first handle 11 and the second handle 12 are held by hand and the stone is clamped by the clamp 27, for larger stones, the rotation amplitude of the clamp 27 when clamping the stone will be smaller, so that the distance that the pull rod 23 moves close to the second handle 12 is smaller, so that after the L-shaped rod 310 moves close to the button 39, the L-shaped rod 310 is away from the pull rod 2 One end of the L-shaped rod 310 will not be inserted into the limiting hole 311 so as not to hinder the pressing of the button 39, so that larger stones can be crushed by the lithotripsy electrode 34. On the contrary, for smaller stones, the rotation amplitude of the clamping member 27 when clamping the stone will be larger, so that the pull rod 23 moves closer to the second handle 12 for a larger distance, so that one end of the L-shaped rod 310 moves closer to the button 39 and then inserts into the limiting hole 311, thereby hindering the pressing of the button 39, so that smaller stones will not be crushed, and further crushing of smaller stones will be prevented, and smaller stones will be crushed smaller, which may cause leakage of the collected stones, which is not conducive to the clamping and collection of the stones.
