[0002] With the continuous development of medical technology, medical means are also constantly being upgraded. Laparoscopy is one of the medical means. Similar to electronic gastroscopy, laparoscope is a medical device with a miniature camera. Laparoscopic surgery is a surgery performed using a laparoscope and related instruments. During laparoscopic surgery, a small hole is opened in the patient's abdomen, and the laparoscope and related surgical instruments are passed through the small hole into the abdominal cavity to perform the surgery. Compared with ordinary open surgery, laparoscopic surgery has the advantages of quick recovery, short hospitalization time, good abdominal cosmetic effect, and less pelvic adhesion. Therefore, it has been widely used. During the operation, some tissues or foreign bodies need to be removed. After the resection is completed, the foreign bodies in the abdominal cavity are removed by a retriever.

[0003] In the prior art, the existing retriever can only remove one foreign body at a time during surgery. After clamping the foreign body, the retriever needs to be taken out, the foreign body needs to be placed, and then the retriever needs to be inserted into the patient's body to retrieve the foreign body again. Multiple removals and insertions greatly reduce the efficiency of the surgery and may cause secondary injuries to the patient, reducing the safety of the surgery. Summary of the invention

After the foreign matter falls into the storage tank, the third gear and the third rack are set, and during the reset process of the slide, the third gear and the third rack are meshed, so that the paddle pushes the foreign matter to the rear of the storage tank, leaving the front position free, thereby preventing the foreign matter from accumulating in the front, thereby ensuring that the subsequent foreign matter can fall into the storage tank more smoothly, and at the same time greatly improving the storage effect of the storage tank, and ensuring that more foreign matter can be stored; 5. Through the setting of the rubber bag, during the process of clamping foreign objects, the rubber bag can be deformed according to the shape of the foreign object, so that the rubber bag can fit the foreign object more fully, thereby producing a better clamping effect, ensuring a better clamping effect for foreign objects of different shapes, preventing the clamped object from slipping, and ensuring stable clamping; 6. Medical sodium hyaluronate gel acts as the pressure liquid in the clamp. Even if there is an internal leakage, the medical sodium hyaluronate gel will not affect the patient's body, avoiding foreign objects in the retriever after leakage that may cause discomfort to the patient, further improving the surgical safety of the retriever.

DETAILED DESCRIPTION

[0018] Reference Figure 1-9 , a quick abdominal foreign body extractor, comprising a hollow handle 1, the handle 1 is penetrated and fixedly connected with a fixed cylinder 2, the cross section of the fixed cylinder 2 is, the fixed cylinder 2 is penetrated and slidably connected with a sliding cylinder 3, and a clamping mechanism is arranged in the sliding cylinder 3; The clamping mechanism includes two sliding plates 4, which are slidably connected in the sliding cylinder 3, and two first racks 6 are fixedly connected to the side walls of the sliding plate 4. The sliding cylinder 3 is rotatably connected to a rotating shaft 7 through a bearing, and the rotating shaft 7 is fixedly connected to two second gears 9. The rotating shaft 7 is rotatably connected to a first gear 8 through a bearing, and a damping washer is arranged between the first gear 8 and the rotating shaft 7. The arrangement of the damping washer makes the rotation between the first gear 8 and the rotating shaft 7 have a certain friction resistance, and the first gear 8 can drive the rotating shaft 7 to rotate through the friction resistance. When the rotating shaft 7 cannot rotate, the first gear 8 can overcome the friction force and rotate relative to the rotating shaft 7. The rack 6 is meshed with the first gear 8, and the upper surface of the slide cylinder 3 is fixedly connected to a limit block 10, and the limit block 10 is a hollow structure. The rotating shaft 7 and the limit block 10 are rotatably connected through a bearing and extend into the interior thereof. A first spring 11 is fixedly connected between the rotating shaft 7 and the inner bottom wall of the limit block 10. The first spring 11 is a torsion spring, so that the rotating shaft 7 can be reversed under its elastic force. The side wall of the sliding plate 4 away from the first rack 6 is fixedly connected with a clamping block 5, and a limit groove 47 is provided on the inner top wall of the fixed cylinder 2. The limit block 10 is slidably connected to the fixed cylinder 2 through the limit groove 47, and a second spring 12 is fixedly connected between the limit block 10 and the inner side wall of the limit groove 47.The clamping mechanism also includes a functional block 13, which is slidably connected inside the slide 3. A sliding groove 18 is provided on the side wall of the functional block 13 close to the first gear 8. The functional block 13 is slidably connected to the second rack 19 through the sliding groove 18. A liquid groove 16 is provided on the inner side wall of the sliding groove 18. A piston 17 is sealed and slidably connected in the liquid groove 16. A connecting rod 20 is fixedly connected between the piston 17 and the second rack 19. A groove 21 is provided on the side wall of the functional block 13 away from the first gear 8. A driving block 23 is sealed and slidably connected in the groove 21. A through hole 22 is provided in the functional block 13. The through hole 22 connects the liquid groove 16 with the groove 21. Both the liquid groove 16 and the groove 21 are filled with pressure liquid. The groove 21 The two opposite inner side walls are fixedly connected with the second block 24, and the fourth spring 25 is fixedly connected between the driving block 23 and the second block 24. The two opposite inner side walls of the slide 3 are fixedly connected with the first block 14, and the third spring 15 is fixedly connected between the functional block 13 and the first block 14. When the wire rope 26 is wound, the driving block 23 is pulled first, and the movement of the driving block 23 draws the hydraulic oil in the liquid tank 16 into the groove 21 through the through hole 22, so that the piston 17 slides, and the piston 17 drives the second rack 19 to move through the connecting rod 20, so that the second rack 19 is meshed with the first gear 8, and then the wire rope 26 continues to pull the driving block 23, and at this time the driving block 23 will drive the functional block 13 to slide, and the functional block 13 will be driven to rotate. The sliding of the energy block 13 will cause the second rack 19 to move, driving the first gear 8 meshing with it to rotate. The rotation of the first gear 8 will drive the rotating shaft 7 to rotate through the friction force, thereby causing the two second gears 9 to rotate. The rotation of the second gear 9, through the meshing with the two sets of first racks 6, causes the two sliding plates 4 to move toward each other, and then causes the two clamping blocks 5 to move toward each other to clamp the foreign matter. Then the functional block 13 drives the slide 3 to move into the fixed cylinder 2. When the foreign matter enters the fixed cylinder 2 and moves to the top of the storage groove 27, the second spring 12 is compressed to the limit state, so that the slide 3 cannot continue to move at this time. At this time, the second rack 19 is still in meshing with the first gear 8. The second rack 19 The movement will drive the first gear 8 to rotate, so that the first gear 8 overcomes the friction between it and the rotating shaft 7 and rotates relative to the rotating shaft 7 until the second rack 19 disengages from the first gear 8. After the first gear 8 disengages from the second rack 19, the elastic force accumulated in the first spring 11 is released, causing the rotating shaft 7 to rotate in the opposite direction. The reverse rotation of the rotating shaft 7 will engage with the first rack 6, causing the two sliding plates 4 to move in opposite directions, thereby causing the two clamping blocks 5 to move in opposite directions to release the clamped foreign objects. At this time, the foreign objects will fall down for storage, so that the retriever can enter the patient's abdominal cavity once to complete multiple retrieval operations. There is no need to take out and insert the retriever into the patient's body multiple times, which greatly improves the surgical efficiency.

[0019] It is worth mentioning that multiple retrieval operations can be completed with one entry into the abdomen, without the need to take out the retriever and insert it again multiple times, thus avoiding secondary harm to the patient caused by the removal and insertion operations and greatly improving the safety of the operation.

[0020] An operating mechanism is provided in the handle 1, and the operating mechanism includes a driven shaft 34, which is rotatably connected to the inner wall of the handle 1 through a bearing, and the driven shaft 34 is fixedly connected to a rope drum 36 and two fourth gears 35, and the rope drum 36 is fixedly connected to the wire rope 26, and the wire rope 26 is fixedly connected to the side wall of the driving block 23 at one end away from the rope drum 36, and the inner wall of the handle 1 is rotatably connected to a driving shaft 37 through a bearing, and the driving shaft 37 is fixedly connected to a fifth gear 38, and the fifth gear 38 is meshed with the corresponding fourth gear 35, and the side wall of the handle 1 is slidably connected to two trigger rods 3 9. One end of the two trigger rods 39 located inside the handle 1 is fixedly connected to the fourth rack 40, and the fourth rack 40 is meshed with the corresponding fifth gear 38. One end of the two trigger rods 39 located outside the handle 1 is commonly fixedly connected to a pressing block 41. It only needs to operate the pressing block 41 to make the trigger rod 39 drive the fourth rack 40 to move, so as to complete the clamping, movement, contact clamping and resetting of the foreign body, so that the medical staff only needs to operate the pressing block 41, without having to be distracted to perform other operations, and can focus more on the status of the patient's abdominal cavity, while greatly improving the automation degree of the retriever.

[0021] A storage mechanism is provided in the fixed cylinder 2, and the storage mechanism includes a storage slot 27, and the storage slot 27 is opened in the fixed cylinder 2. The fixed cylinder 2 is rotatably connected to a slot cover 28 through a hinge, and the slot cover 28 ensures that the storage slot 27 is blocked, and it is provided with a lock buckle (not shown in the figure) to ensure that the slot cover 28 will not be opened during use. A sliding rod 30 is slidably connected to the fixed cylinder 2, one end of the sliding rod 30 extends through the storage slot 27 and is fixedly connected to a paddle 29, and the other end extends to the outside of the storage slot 27, one end of the sliding rod 30 located outside the storage slot 27 and the lower surface of the sliding cylinder 3 are fixedly connected to a third rack 33, and a fixed rod 31 is fixedly connected to the inner side wall of the fixed cylinder 2, and the fixed rod 31 is rotatably connected to a third gear 32 through a bearing, and the two third racks 33 are meshed with the third gear 32, and the two third racks 33 are symmetrically arranged about the third gear 32 (such as Figure 4When the foreign object falls into the storage groove 27 and the slide cylinder 3 is reset, the third gear 32 is engaged with the third rack 33, and the paddle plate 29 moves in the direction close to the third gear 32, pushing the foreign object that has just fallen into the storage groove 27 to the rear part of the storage groove 27. When the foreign object falls into the storage groove 27, it is automatically pushed to the rear part of the storage groove 27 to avoid the accumulation of foreign objects in the front part of the storage groove 27, thereby ensuring that subsequent foreign objects can fall into the storage groove 27 more smoothly, and at the same time greatly improve the storage effect of the storage groove 27, and can ensure that more foreign objects are stored.

[0022] The clamp block 5 is a hollow structure. The side walls of the two clamp blocks 5 on the opposite sides are fixedly connected with rubber sacs 42. A fixed tube 43 is passed through the clamp block 5 and fixedly connected. The fixed tube 43 connects the rubber sac 42 with the inside of the clamp block 5. Two pressure plates 44 are sealed and slidably connected inside the clamp block 5. A hole (not shown in the figure) is opened on the side wall of the clamp block 5, so that the space inside the clamp block 5 outside the two pressure plates 44 is connected with the outside world, thereby ensuring that the sealed and slidable pressure plates 44 can slide freely. A plurality of fifth springs 45 are fixedly connected between the pressure plates 44 and the inner side walls of the clamp block 5. The rubber sac 42 and the clamp block 5 are filled with pressure liquid. When the two clamp blocks 5 move toward each other, they move simultaneously to The foreign object approaches and makes the rubber bag 42 contact with the foreign object. As the clamping block 5 moves, the rubber bag 42 gradually contacts with the foreign object and changes its shape along with the shape of the foreign object. The change in shape makes the internal pressure liquid enter the clamping block 5 through the fixed tube 43, thereby making the pressure plate 44 slide and compressing the fifth spring 45 until the pressure plate 44 moves to the limit position and cannot move. At this time, the rubber bag 42 clamps the foreign object. At the same time, the rubber bag 42 changes its own shape according to the shape of the clamped foreign object to ensure full fit with the foreign object, so that the retriever can clamp foreign objects of different shapes well and prevent the clamped foreign objects from falling off again.

[0023] A limiting rod 46 is fixedly connected between the two opposite inner walls of the slide cylinder 3, and the sliding plate 4 is slidably connected to the limiting rod 46. The setting of the limiting rod 46 can play a certain limiting role in the movement of the sliding plate 4, so that the two sliding plates 4 can move stably along the limiting rod 46, thereby avoiding deflection during the movement.

[0024] The pressure liquid filled in the liquid tank 16 and the groove 21 is hydraulic oil. The pressure liquid filled in the rubber bag 42 and the clamping block 5 is medical sodium hyaluronate gel, which is a colorless and transparent gel solution composed of high-purity sodium hyaluronate and physiological buffer balance salt. It is sealed in the rubber bag 42 and the clamping block 5 to ensure a sterile environment. Therefore, even if it leaks, it will not affect the human body, thereby avoiding foreign matter in the retriever after leakage, causing discomfort to the patient, and further improving the surgical safety of the retriever.

[0025] The cross section of the sliding plate 4 is a concave shape with the opening facing one side (such as Fig. 9 As shown), the second rack 19 can pass through the sliding plate 4, ensuring that the second rack 19 will not interfere with the movement of the sliding plate 4, and the lengths of the two sliding plates 4 are inconsistent. The inconsistent lengths ensure that the two groups of first racks 6 are symmetrical about the second gear 9, thereby ensuring that the rotation of the second gear 9 can make the two sliding plates 4 move in opposite directions.

[0026] The pressing block 41 is made of rubber and has anti-skid patterns carved on its outer wall, so that slipping can be avoided when the pressing block 41 is operated, thereby ensuring the stability of the operation of the retriever.

[0027] In the present invention, the retriever is inserted into the abdominal cavity, and the foreign body is searched for through the laparoscope. After the foreign body is found, the retriever is operated so that the foreign body is located between the two clamping blocks 5, and then the pressing block 41 is operated to make the trigger rod 39 drive the fourth rack 40 to move, and the movement of the fourth rack 40 drives the fifth gear 38 to rotate, and the fifth gear 38 drives the fourth gear 35 meshing therewith to rotate, so that the fourth gear 35 drives the rope drum 36 to rotate through the driven shaft 34, and the rope drum 36 can reel up the wire rope 26.

[0028] When the wire rope 26 is wound, the driving block 23 is pulled first. The movement of the driving block 23 draws the hydraulic oil in the liquid tank 16 into the groove 21 through the through hole 22, so that the piston 17 slides. The piston 17 drives the second rack 19 to move through the connecting rod 20, so that the second rack 19 meshes with the first gear 8, and then the wire rope 26 continues to pull the driving block 23. At this time, the driving block 23 will drive the functional block 13 to slide. The sliding of the functional block 13 will move the second rack 19, driving the first gear 8 meshing with it to rotate. The rotation of the first gear 8 will drive the rotating shaft 7 to rotate through the friction force, so that the two second gears 9 rotate. The rotation of the second gear 9, through the meshing with the two groups of first racks 6, makes the two sliding plates 4 move toward each other, and then makes the two clamping blocks 5 move toward each other.

[0029] When the two clamping blocks 5 move toward each other, they simultaneously approach the foreign object and make the rubber bag 42 contact with the foreign object. As the clamping blocks 5 move, the rubber bag 42 gradually contacts with the foreign object and changes its shape along with the shape of the foreign object. The change in shape makes the internal pressure liquid enter the clamping block 5 through the fixed tube 43, thereby making the pressure plate 44 slide and compressing the fifth spring 45 until the pressure plate 44 moves to the limit position and cannot move anymore. At this time, the rubber bag 42 clamps the foreign object and the clamping block 5 cannot move anymore.

[0030] At this time, the functional block 13 continues to move, while the clamping block 5 cannot continue to move, so that the sliding plate 4 cannot move, that is, the first rack 6 cannot continue to move, and the first rack 6 is engaged with the second gear 9. At this time, the second gear 9 cannot rotate, and the rotating shaft 7 cannot rotate. At this time, the second rack 19 is still moving with the functional block 13. At this time, through the engagement of the second rack 19 with the first gear 8, the first gear 8 will drive the entire slide cylinder 3 to slide and slide into the inside of the fixed cylinder 2, bringing the clamped foreign matter into the fixed cylinder 2, and compressing the second spring 12 at the same time. At the same time, through the engagement of the third rack 33 with the third gear 32, the paddle plate 29 moves in the direction away from the third gear 32.

[0031] When the foreign object enters the fixed cylinder 2 and moves to the top of the storage groove 27, the second spring 12 is compressed to the limit state, so that the slide cylinder 3 cannot continue to move at this time, and the second rack 19 and the first gear 8 are still in meshing state. The movement of the second rack 19 will drive the first gear 8 to rotate, so that the first gear 8 overcomes the friction between the second rack 19 and the rotating shaft 7 and rotates relative to the rotating shaft 7 until the second rack 19 is disengaged from the first gear 8. After the first gear 8 is disengaged from the second rack 19, the elastic force accumulated in the first spring 11 is released, so that the rotating shaft 7 rotates in the opposite direction. The reverse rotation of the rotating shaft 7 will mesh with the first rack 6, so that the two sliding plates 4 move in opposite directions, thereby making the two clamping blocks 5 move in opposite directions to loosen the clamped foreign object. At this time, the foreign object will fall into the storage groove 27. While releasing the clamping of the foreign object, under the elastic force of the fifth spring 45, the pressure plate 44 is reset, and the pressure liquid is pumped back into the rubber bag 42, so that the rubber bag 42 returns to its original state.

[0032] After the foreign object is sent into the fixed cylinder 2, the pressing block 41 is released, and the driving block 23 is reset under the elastic force of the fourth spring 25. At the same time, the functional block 13 is reset under the elastic force of the third spring 15. Under the elastic force of the second spring 12, the slide cylinder 3 slides back and resets, and the reset of the driving block 23 will pump the hydraulic oil back into the liquid tank 16 through the through hole 22, so that the piston 17 drives the second rack 19 to slide, so that when the functional block 13 is reset, the second rack 19 will not mesh with the first gear 8, and at the same time as the slide cylinder 3 is reset, the third gear 32 is meshed with the third rack 33, and the paddle 29 moves in the direction of approaching the third gear 32, pushing the foreign object that has just fallen into the storage groove 27 to the rear of the storage groove 27.

[0033] At this time, continue to look for the next foreign object. After finding it, make sure that the foreign object is located between the two clamping blocks 5, and continue to clamp and store the foreign objects according to the above operations. When all foreign objects are clamped and stored, take out the retriever, open the slot cover 28, take out the foreign objects stored inside, and disinfect the entire retriever.
