Description

Technical Field

[0001] The invention belongs to the technical field of retractors, in particular to a laparoscopic liver lobe lifting device. Background Art

[0002] The liver lobe lifting device is a medical device specifically used to lift the liver lobe during laparoscopic surgery. By lifting the liver lobe, it provides surgeons with a clearer surgical field of view, allowing them to more accurately locate and operate the surgical site.

[0003] In the prior art, the liver lobe lifting device is first connected to the laparoscopic system, and then under the monitoring of the laparoscope, the needle tube part of the device is inserted into the abdominal cavity and close to the liver lobe that needs to be pulled. When the needle tube reaches the target position, the doctor will operate the push rod to open the spring grasping forceps head and grasp the liver lobe. After grasping the liver lobe, the doctor releases the push rod. At this time, the elastic reset device will keep the forceps head at a certain pulling force, thereby grasping the liver lobe. Then, the lifting direction of the liver lobe is controlled by controlling the direction of the device, thereby exposing a clearer surgical field.

[0004] The above scheme still has some shortcomings in actual use. After the spring grasper grasps the liver lobe, the doctor will release the push rod and use the elastic reset device to make the spring grasper lift the liver lobe. At this time, the spring grasper completely grasps the liver lobe. Since the tissue in the human body is relatively fragile and in order to expose the required surgical field of view, after the spring grasper grasps the liver lobe, it is necessary to control the position of the spring grasper so that the liver lobe no longer blocks the surgical field of view. This process may cause damage to the liver lobe. Therefore, in actual use, the doctor will release the push rod to a certain distance so that the spring grasper will not completely grasp the liver lobe. At the same time, the doctor will wear gloves on his hands during the operation. Long-term surgery and control of the push rod may cause the doctor's hands in the gloves to sweat, reduce the friction between the hands and the gloves, and cause the doctor's hands to slide between the gloves when controlling the lifting device, so that the device fails to move to the required position.

[0005] To this end, the present invention provides a laparoscopic liver lobe lifting device. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve the technical problem is as follows: the laparoscopic liver lobe lifting device described in the present invention comprises a syringe, one end of the syringe is fixedly connected to a bottom baffle, a guide groove 1 is symmetrically provided inside the syringe, a push rod is slidably connected inside the syringe, one end of the syringe is fixedly connected to a needle, one end of the push rod is fixedly connected to a spring gripper, and a return spring is fixedly connected between the bottom baffle and the push rod;

[0008] The syringe is provided with an anti-slip component, which includes symmetrically arranged half-ring sleeves, each of which is fixedly provided with a ring. During surgery, two fingers are passed through the corresponding rings and then the operation is performed to prevent the friction between the hands and the gloves from being reduced due to sweating during the operation, resulting in the device failing to move to the desired position when operating the device.

[0009] Preferably, one end of the push rod slides in one of the two guide grooves, the spring gripper penetrates the bottom baffle, and the spring gripper slides in the needle.

[0010] Preferably, the anti-slip component further comprises a sliding groove, which is provided on the surface of the syringe, and the two half-ring sleeves both slide in the sliding groove.

[0011] Preferably, each half-ring sleeve is provided with a snap-fit ​​groove, and each sleeve ring is fixedly arranged in the snap-fit ​​groove.

[0012] Preferably, each collar is provided with a displacement groove 1 at the bottom, each collar is provided with a displacement groove 2 in the middle, and two guide grooves 2 are provided between each displacement groove 1 and displacement groove 2.

[0013] Preferably, the two guide grooves 2 are both connected to the displacement groove 1 and the displacement groove 2, and the two guide grooves 2 are staggered and symmetrically arranged.

[0014] Preferably, a clamping block is symmetrically and slidably connected inside the displacement groove 1, a compression spring 1 is fixedly connected between the two clamping blocks, a gear is rotatably connected inside the displacement groove 2, a displacement rack rod 1 is slidably connected on one side inside the displacement groove 2, and a displacement rack rod 2 is slidably connected on the other side inside the displacement groove 2.

[0016] Preferably, the semi-ring sleeve is provided with a quick installation and disassembly component, and the quick installation and disassembly component includes two self-locking grooves 1, which are opened at both ends of a semi-ring sleeve, and the top of each self-locking groove 1 is symmetrically fixedly connected with a blocking block, and the two ends of the other semi-ring sleeve are fixedly connected with a spring tongue, and the top of each spring tongue is fixedly connected with a press buckle.

[0017] Preferably, the shape of the self-locking groove 1 matches the shape of the spring tongue.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The present invention allows the doctor to pass the index finger and the middle finger of the left hand through two rings respectively, and control the spring grasping forceps to clamp the liver lobe by pressing the push rod with the thumb. Compared with the existing device, the ring can prevent the doctor's hand from gradually sliding on the syringe when the push rod is continuously controlled during a long operation, resulting in different degrees of tightness of the spring grasping forceps clamping the liver lobe, which may cause damage to the liver lobe. It plays an anti-slip role and improves the stability of using this device to clamp the liver lobe; at the same time, when the opening of the spring grasping forceps is not parallel to the liver lobe to be clamped, because the semi-ring sleeve slides on the sliding groove, the syringe can be rotated for adjustment at this time, thereby ensuring the flexibility of the device; in addition, the ring can be disassembled and assembled, which is further convenient for disinfection before and after use.

[0020] 2. The present invention fixes the two semi-ring sleeves by sliding the spring tongue into the self-locking groove 1 and then being limited by the self-locking groove 1 and the blocking block, thereby forming a circular ring, which slides on the surface of the syringe. By pressing the push buckle, the spring tongue slides out of the self-locking groove 1, and the two semi-ring sleeves are disassembled, so that when cleaning and disinfecting, the contact area for cleaning and disinfection is increased, so that it can be better cleaned and disinfected. At the same time, through quick installation and disassembly, the device can be better stored and parts replaced. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] Embodiment 1

[0035] like Figures 1 to 8 As shown, a laparoscopic liver lobe lifting device according to an embodiment of the present invention comprises a syringe 1, one end of the syringe 1 is fixedly connected to a bottom baffle 11, a guide groove 12 is symmetrically provided inside the syringe 1, a push rod 13 is slidably connected inside the syringe 1, a needle 14 is fixedly connected to one end of the syringe 1, a spring gripper 15 is fixedly connected to one end of the push rod 13, a return spring 16 is fixedly connected between the bottom baffle 11 and the push rod 13, one end of the push rod 13 slides in two guide grooves 12, the spring gripper 15 penetrates the bottom baffle 11, and the spring gripper 15 slides in the needle 14;

[0036] The syringe 1 is provided with an anti-slip component, which includes symmetrically arranged half-ring sleeves 22, each of which is fixedly provided with a ring 24. During surgery, two fingers are passed through the corresponding rings 24 and then the operation is performed to prevent the friction between the hands and the gloves from being reduced due to sweating during the operation, resulting in the device failing to move to the desired position when operating the device.

[0037] Specifically, the above scheme still has some shortcomings during actual use. After the spring grasper 15 grasps the liver lobe, the doctor will release the push rod 13 and use the reset spring 16 to make the spring grasper 15 lift the liver lobe. At this time, the spring grasper 15 completely grasps the liver lobe. Since the tissue in the human body is relatively fragile and in order to expose the required surgical field of view, after the spring grasper 15 grasps the liver lobe, it is necessary to control the position of the spring grasper 15 so that the liver lobe no longer blocks the surgical field of view. This process may cause damage to the liver lobe. Therefore, during actual use, the doctor will release the push rod 13 to a certain distance so that the spring grasper 15 will not completely grasp the liver lobe. At the same time, the doctor will wear gloves on his hands during the operation. Long-term surgery and control of the push rod 13 may cause the doctor's hands in the gloves to sweat, reduce the friction between the hands and the gloves, and cause the doctor's hands to slide between the gloves when controlling the lifting device, so that the device fails to move to the required position.

[0038] Therefore, the present invention solves this problem by setting a corresponding structure. Before the operation, the liver lobe lifting device is first connected to the laparoscope system, and then the doctor passes the index finger and middle finger of the left hand through the two rings 24 respectively, and makes the thumb contact one end of the push rod 13, and then performs the operation. Under the monitoring of the laparoscope, the needle 14 is inserted into the abdominal cavity and close to the liver lobe that needs to be pulled. When the needle 14 reaches the target position, the doctor will operate the push rod 13 to make the spring grasper 15 slide out of the needle 14. When the spring grasper 15 slides out of the needle 14, it will open, and then the spring grasper 15 will contact the liver lobe. Then, the doctor releases the push rod 13 to a certain distance, and under the elastic reset action of the reset spring 16, the spring grasper 15 is partially retracted into the needle 14 and clamps the liver lobe. Then, the lifting direction of the liver lobe is controlled by the direction of the control device, thereby exposing a clearer surgical field.

[0039] Embodiment 2

[0040] like Figures 2 to 8 As shown, compared with Example 1, another implementation of the present invention is:

[0041] like Figures 2 to 5 As shown, the anti-slip assembly of this embodiment also includes a sliding groove 21, which is provided on the surface of the syringe 1, and two semi-ring sleeves 22 slide in the sliding groove 21, each semi-ring sleeve 22 is provided with a clamping groove 23, each collar 24 is fixedly arranged in the clamping groove 23, each collar 24 is provided with a displacement groove 1 25 at the bottom, each collar 24 is provided with a displacement groove 2 26 in the middle, and two guide grooves 214 are provided between each displacement groove 1 25 and the displacement groove 2 26, and the two guide grooves 214 are connected to the displacement groove 1 25 and the displacement groove 2 26, and the two guide grooves 214 are staggered and symmetrically arranged;

[0042] A clamping block 27 is symmetrically slidably connected in the displacement groove 1 25, a compression spring 1 28 is fixedly connected between the two clamping blocks 27, a gear 211 is rotatably connected inside the displacement groove 26, a displacement rack rod 1 29 is slidably connected to one side of the displacement groove 26, and a displacement rack rod 210 is slidably connected to the other side of the displacement groove 26;

[0043] The displacement rack rod 1 29 and the displacement rack rod 210 are staggered, and a guide rod 1 212 is fixedly connected between the displacement rack rod 1 29 and a clamping block 27 below it. The guide rod 1 212 slides in a guide groove 214, and a guide rod 213 is fixedly connected between the displacement rack rod 210 and another clamping block 27 below it. The guide rod 213 slides in another guide groove 214.

[0044] Specifically, the shape of the clamping groove 23 matches the shape of the bottom of the collar 24, the shape of the clamping block 27 is convex, and its wider part slides in the displacement groove 1 25, the clamping groove 23 is a cylindrical groove, and the inner wall of the bottom is provided with two symmetrical grooves, and the shape of the grooves matches one end of the narrower part of the clamping block 27, and the gear 211 is meshed with the displacement rack rod 1 29 and the displacement rack rod 2 210 on both sides thereof;

[0045] Initially, the compression spring 1 28 is not deformed, one end of the wider portion of the clamping block 27 abuts against the inner wall of one side of the displacement groove 1 25 , the narrower portion of the clamping block 27 is located outside the bottom surface of the collar 24 , and one end of the displacement rack rod 210 is located outside the displacement groove 26 ;

[0046] Before the operation, the device is first disinfected and then assembled. During this process, the displacement rack rod 210 is first pressed to make the displacement rack rod 210 completely slide into the displacement groove 26. The movement of the displacement rack rod 210 drives the displacement rack rod 1 29 to move synchronously through the gear 211, thereby moving the two clamping blocks 27 toward the middle of the collar 24 and elastically compressing the compression spring 1 28, so that the clamping block 27 is completely in the displacement groove 1 25.

[0047] At this time, the bottom of the collar 24 is placed into the clamping groove 23, and then the displacement rack rod 210 is no longer pressed. Since the shape of the clamping groove 23 matches the shape of the bottom of the collar 24, the compression spring 1 28 remains in an elastically compressed state, and the displacement rack rod 210 continues to be completely retracted in the displacement groove 26;

[0048] Then, the collar 24 is rotated. During this process, when the displacement groove 1 25 corresponds to the groove on the bottom inner wall of the clamping groove 23, the clamping block 27 is reset under the elastic compression of the compression spring 1 28, so that one end of the clamping block 27 slides to the groove on the bottom inner wall of the clamping groove 23, so that the collar 24 is clamped and then fixed on the semi-ring sleeve 22. At this time, the displacement rack rod 210 is reset;

[0049] Then, the two half ring sleeves 22 are placed on the sliding groove 21 and the two half ring sleeves 22 are fixed to each other, thereby completing the assembly;

[0050] When using this device, the doctor passes the index finger and middle finger of the left hand through the two rings 24 respectively, and controls the spring grasper 15 to clamp the liver lobe by pressing the push rod 13 with the thumb. Compared with the existing device, the ring 24 can prevent the doctor's hand from gradually sliding on the syringe 1 when the push rod 13 is continuously controlled during a long operation, resulting in different degrees of tightness of the spring grasper 15 clamping the liver lobe, which may cause damage to the liver lobe. It plays an anti-slip role and improves the stability of clamping the liver lobe using this device; at the same time, when the opening of the spring grasper 15 is not parallel to the liver lobe to be clamped, because the semi-ring sleeve 22 slides on the sliding groove 21, the syringe 1 can be rotated for adjustment, thereby ensuring the flexibility of the device; in addition, the ring 24 can be disassembled and assembled, which further facilitates disinfection before and after use.

[0051] like Figures 6 to 8 As shown, in this embodiment, a quick installation and disassembly component is provided on the semi-ring sleeve 22, and the quick installation and disassembly component includes two self-locking grooves 31. The two self-locking grooves 31 are opened at both ends of a semi-ring sleeve 22, and the top of each self-locking groove 31 is symmetrically fixedly connected with a blocking block 32, and the two ends of the other semi-ring sleeve 22 are fixedly connected with a spring tongue 33, and the top of each spring tongue 33 is fixedly connected with a press buckle 34, and the shape of the self-locking groove 31 matches the shape of the spring tongue 33.

[0052] Specifically, in the process that the two ends of the two semi-ring sleeves 22 conflict with each other, one end of the spring tongue 33 first slides into the self-locking groove 1 31, and the top surface of the spring tongue 33 conflicts with the bottom of the blocking block 32. As the spring tongue 33 continues to slide, the top of the spring tongue 33 elastically deforms under the limiting action of the self-locking groove 1 31 and the blocking block 32, so that the top of the spring tongue 33 is compressed in the direction close to the bottom of the spring tongue 33 until the top of the spring tongue 33 slides over the blocking block 32. At this time, the top of the spring tongue 33 elastically resets, so that the top of the spring tongue 33 conflicts with one end of the blocking block 32. At this time, the pressing buckle 34 fits with the top of the self-locking groove 1 31, thereby completing the fixation between the two semi-ring sleeves 22;

[0053] After the operation is completed, the device needs to be disinfected and cleaned. At this time, by pressing the two push buckles 34, the top of the spring tongue 33 is elastically compressed toward the bottom of the spring tongue 33, and then the push buckle 34 is moved outward to make the spring tongue 33 slide out of the self-locking groove 31, thereby completing the disassembly of the two half-ring sleeves 22.

[0054] The present invention completes the fixation of the two semi-ring sleeves 22 by sliding the spring tongue 33 into the self-locking groove 31 and being limited by the self-locking groove 31 and the blocking block 32, thereby forming a circular ring, which slides on the surface of the syringe 1. By pressing the pressing buckle 34, the spring tongue 33 slides out of the self-locking groove 31, and the disassembly of the two semi-ring sleeves 22 is completed, so that when cleaning and disinfecting, the contact area for cleaning and disinfection is increased, so that it can be better cleaned and disinfected. At the same time, through rapid installation and disassembly, the device can be better stored and parts replaced.

[0055] Working principle:

[0056] Before the operation, the device is first disinfected and then assembled. During this process, the displacement rack rod 210 is first pressed to make the displacement rack rod 210 completely slide into the displacement groove 26. The movement of the displacement rack rod 210 drives the displacement rack rod 1 29 to move synchronously through the gear 211, thereby making the two clamping blocks 27 move toward the middle of the collar 24 and elastically compress the compression spring 1 28, so that the clamping block 27 is completely in the displacement groove 1 25.

[0057] At this time, the bottom of the collar 24 is placed into the clamping groove 23, and then the displacement rack rod 210 is no longer pressed. Since the shape of the clamping groove 23 matches the shape of the bottom of the collar 24, the compression spring 1 28 remains in an elastically compressed state, and the displacement rack rod 210 continues to be completely retracted in the displacement groove 26;

[0058] Then, the collar 24 is rotated. During this process, when the displacement groove 1 25 corresponds to the groove on the bottom inner wall of the clamping groove 23, the clamping block 27 is reset under the elastic compression of the compression spring 1 28, so that one end of the clamping block 27 slides to the groove on the bottom inner wall of the clamping groove 23, so that the collar 24 is clamped and then fixed on the semi-ring sleeve 22. At this time, the displacement rack rod 210 is reset;

[0059] The two ends of the two half-ring sleeves 22 are then brought into contact with each other. During this process, one end of the spring tongue 33 first slides into the self-locking groove 1 31, and the top surface of the spring tongue 33 conflicts with the bottom of the blocking block 32. As the spring tongue 33 continues to slide, the top of the spring tongue 33 elastically deforms under the limiting action of the self-locking groove 1 31 and the blocking block 32, so that the top of the spring tongue 33 is compressed in the direction close to the bottom of the spring tongue 33 until the top of the spring tongue 33 slides over the blocking block 32. At this time, the top of the spring tongue 33 elastically resets, so that the top of the spring tongue 33 conflicts with one end of the blocking block 32. At this time, the pressing buckle 34 fits with the top of the self-locking groove 1 31, thereby completing the fixation between the two half-ring sleeves 22, and then completing the assembly of the device;

[0060] Then, the liver lobe lifting device is connected to the laparoscope system, and then the doctor passes the index finger and middle finger of the left hand through the two rings 24 respectively, and controls the spring grasping forceps 15 to clamp the liver lobe by pressing the push rod 13 with the thumb, and then performs the operation. Under the monitoring of the laparoscope, the needle 14 is inserted into the abdominal cavity and close to the liver lobe that needs to be pulled. When the needle 14 reaches the target position, the doctor will operate the push rod 13 to make the spring grasping forceps 15 slide out of the needle 14. When the spring grasping forceps 15 slide out of the needle 14, it will open, and then the spring grasping forceps 15 will contact the liver lobe. Then, the doctor releases the push rod 13 to a certain distance, and under the elastic reset action of the reset spring 16, the spring grasping forceps 15 partially shrinks into the needle 14 and clamps the liver lobe. Then, the lifting direction of the liver lobe is controlled by the direction of the control device, thereby exposing a clearer surgical field.

[0061] After the operation, the device needs to be disinfected and cleaned. At this time, the two push buckles 34 are pressed to elastically compress the top of the spring tongue 33 toward the bottom of the spring tongue 33, and then the push buckle 34 is moved outward to make the spring tongue 33 slide out of the self-locking groove 31, thereby completing the disassembly of the two half-ring sleeves 22. Through the above operation, the ring 24 is disassembled for easy storage and disinfection.

[0062] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
