Abstract
Description
Technical Field
[0001] This invention relates to the field of medical device technology, and in particular to a laparoscopic gallbladder removal device and its usage method. Background Technology
[0002] Cholecystectomy is a surgical procedure to remove the gallbladder (a pear-shaped organ located in the upper right abdomen, directly below the liver). The gallbladder collects and stores bile, a digestive fluid produced in the liver.
[0003] Currently, after gallbladder removal in the abdominal cavity, a pathology bag is usually inserted through the TOCAR port. After the gallbladder is placed in the pathology bag, it is pulled up to the TOCAR port. The gallbladder is generally about 3*2*6cm in size, while the TOCAR port is relatively small (about 1-1.2cm). If the gallbladder removal goes smoothly, it takes 5-10 minutes, but if it does not go smoothly, it can often take 20-30 minutes. The reason for this is that the TOCAR port in laparoscopy is relatively small (about 1-1.2cm), and most doctors are unwilling to lengthen the TOCAR port diameter, as lengthening the incision does not achieve the desired minimally invasive and aesthetic effect. Summary of the Invention
[0004] To address the aforementioned problems, this invention provides a laparoscopic gallbladder removal device and its usage method.
[0005] In a first aspect, the present invention provides a laparoscopic gallbladder removal device, which adopts the following technical solution: A laparoscopic gallbladder removal device includes a first sleeve, a sampling mechanism, and a clamping mechanism. The sampling mechanism includes a second sleeve, a connecting rod, and clamping plates. The second sleeve is slidably connected to the first sleeve, and the clamping plates are rotatably connected to one end of the first sleeve. Multiple clamping plates are provided, and clamping cavities are formed between the multiple clamping plates. One end of the connecting rod is rotatably connected to the clamping plates, and the other end of the connecting rod is rotatably connected to the second sleeve. The clamping mechanism is slidably connected to the second sleeve for clamping the gallbladder.
[0006] By adopting the above technical solution, when removing the gallbladder, this instrument is inserted into the patient's body. After the instrument is inserted, the second sleeve is pushed to move, which drives the connecting rod to rotate. The connecting rod pushes the clamping plate to rotate, causing the clamping plate to open. Then, the clamping mechanism grasps the cut gallbladder and brings it into the clamping cavity. Pulling the second sleeve causes the clamping plate to close through the connecting rod, enclosing the gallbladder in the clamping cavity. Then, pulling the first sleeve removes the gallbladder from the body. Since the gallbladder is clamped and pulled into the clamping cavity formed by multiple clamping plates after removal, and is brought out of the body by the clamping plates, the step of placing the gallbladder in the pathology bag is omitted, thereby reducing the gallbladder removal time and eliminating the need to enlarge the surgical incision, thus improving the minimally invasive and aesthetic effect.
[0007] Optionally, one end of the first sleeve has a first groove, one end of the second sleeve has a first sliding groove, a first ring is fitted on the first sleeve and the first ring is located in the first groove, a first hole is formed on the clamping piece and the first ring passes through the first hole, the clamping piece is rotatably connected to the first ring, a second ring is slidably connected to the second sleeve and the second ring is slidably connected to the second sleeve through the first sliding groove, one end of the connecting rod is rotatably connected to the clamping piece and the other end of the connecting rod is rotatably connected to the second ring.
[0008] By adopting the above technical solution, when the gallbladder is clamped, the second sleeve is pushed. At this time, the second sleeve drives the clamping mechanism to move towards the open end of the clamping piece. When the end of the first groove moves to the second ring, the second sleeve is pushed further. Since the second sleeve has the first groove, the second sleeve pushes the second ring to move downward. The second ring pushes the connecting rod to rotate, causing the connecting rod to push the clamping piece open. This causes multiple clamping pieces to rotate and open around the first ring. At this time, the clamping mechanism extends out of the clamping cavity to clamp the gallbladder. After the clamping mechanism clamps the gallbladder, the second sleeve is pulled to move the clamping mechanism away from the open end of the clamping piece. When the front end of the first groove moves to the second ring, the second sleeve is pulled further, causing the second sleeve to pull the second ring to move upward. The second ring pulls the connecting rod to rotate, causing the connecting rod to tighten the clamping piece. At this time, the gallbladder is in the clamping cavity formed by multiple clamping pieces. Finally, the instrument is removed from the patient's body.
[0009] Optionally, the sampling mechanism further includes rubber pads, which are disposed on the clamping plates. Multiple rubber pads are provided, and guide grooves are formed on the rubber pads. Each rubber pad corresponds to one clamping plate.
[0010] By adopting the above technical solution, when the clamping mechanism clamps the gallbladder and retracts into the clamping cavity, the clamping plates retract, and since each clamping plate is equipped with a rubber gasket and each rubber gasket has a guide groove, the side of the clamping plate without a rubber gasket is engaged with the rubber gasket with the guide groove on another clamping plate, thereby improving the sealing of the clamping cavity.
[0011] Optionally, the sampling mechanism further includes a first guide sleeve, wherein multiple first guide sleeves are provided, the outer peripheral surface of the first guide sleeve is disposed on the inner peripheral surface of the first sleeve, the first guide sleeve is coaxially disposed with the first sleeve, and the second sleeve is slidably connected in the first guide sleeve.
[0012] By adopting the above technical solution, the setting of the first guide sleeve makes the sliding direction of the second sleeve more accurate when the second sleeve slides in the first sleeve, thereby improving the accuracy of the position when the second sleeve drives the clamping mechanism to extend.
[0013] Optionally, the clamping mechanism includes a first jaw, a second jaw, a pressure rod, a first connecting rod, and a second connecting rod. The pressure rod is slidably connected in the second sleeve. The first jaw and the second jaw are hinged together and rotatably connected to the second sleeve. One end of the first connecting rod is hinged to the first jaw, and the other end of the first connecting rod is hinged to the pressure rod. One end of the second connecting rod is hinged to the second jaw, and the other end of the second connecting rod is hinged to the pressure rod.
[0014] By adopting the above technical solution, when the gallbladder is clamped, the second ring pushes the connecting rod to rotate, causing the connecting rod to push open the clamping plates. This causes multiple clamping plates to rotate and open around the first ring, and the clamping mechanism extends out of the clamping cavity. At this time, the pressure rod is pushed, which pushes the first and second connecting rods, increasing the distance between the ends of the first and second connecting rods away from the pressure rod. This causes the first and second jaws to open. When one end of the first and second jaws reaches the gallbladder position, the second sleeve is gripped, and the pressure rod is pulled, causing the first and second jaws to clamp the gallbladder. After clamping the gallbladder, the pressure rod and the second sleeve are pulled until the gallbladder enters the clamping cavity. Before removing the gallbladder from the body, because the first and second jaws move in the clamping cavity before clamping the gallbladder, they only extend after the clamping plates open, thus reducing harm to the patient.
[0015] Optionally, the clamping mechanism further includes a second guide sleeve, wherein multiple second guide sleeves are provided, the outer peripheral surface of the second guide sleeve is disposed on the inner peripheral surface of the second sleeve, the second guide sleeve is coaxially disposed with the second sleeve, and the pressure rod is slidably connected in the second guide sleeve.
[0016] By adopting the above technical solution, the setting of the second guide sleeve makes the sliding direction of the pressure rod more accurate when it slides in the first sleeve, thereby improving the positional accuracy of the pressure rod when it drives the first and second clamps to extend.
[0017] Optionally, the first sleeve is provided with a first handle at the end away from the clamping piece, the second sleeve is provided with a second handle at the end away from the first clamping jaw, and the pressure rod is provided with a third handle at the end away from the first connecting rod.
[0018] By adopting the above technical solution, the first handle, the second handle, and the second handle configuration make the sliding of the first sleeve or the second sleeve or the pressure rod easier to operate, thereby improving the efficiency of gallbladder removal.
[0019] Secondly, the present invention provides a method for using a laparoscopic gallbladder removal device, comprising the following steps: Step 1: Lift the second and third handles upwards to form a closed clamping cavity with the clamping plates, so that the first and second jaws approach the first sleeve and move closer to each other; Step 2: Insert the instrument into the patient's body, push the third handle to extend the second sleeve, open the clamping plate, and move the first and second jaws away from the first sleeve. Continue to push the third handle to move the first and second jaws away from each other. Step 3: After the first and second clamps contact the gallbladder, grip the second handle and pull the third handle to clamp the gallbladder with the first and second clamps. Then pull the second and third handles to allow the gallbladder to enter the clamping cavity formed by the multiple clamping plates. Step 4: After the multiple clamping plates close, remove the instrument and take the gallbladder out of the body.
[0020] In summary, the present invention has at least one of the following beneficial technical effects: 1. After the gallbladder is removed, it is clamped and pulled into the clamping cavity formed by multiple clamping plates by the clamping mechanism. The gallbladder is then brought out of the body by the clamping plates, thus eliminating the step of putting the gallbladder into the pathology bag, thereby reducing the gallbladder removal time and eliminating the need to enlarge the surgical incision, thus improving the minimally invasive and aesthetic effect.
[0021] 2. Since each clamping piece is equipped with a rubber gasket, and each rubber gasket has a guide groove, the side of the clamping piece without a rubber gasket can be engaged with the rubber gasket of another clamping piece that has a guide groove, thereby improving the sealing of the clamping cavity.
[0022] 3. Before removing the gallbladder from the body, the first and second clamps move within the clamping cavity before the gallbladder is removed. The first and second clamps only extend after the clamping plates open, thus reducing harm to the patient. Attached Figure Description

Detailed Implementation
[0025] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6 The present invention will be described in further detail below.
[0026] This invention discloses a laparoscopic gallbladder removal device and its method of use. (Refer to...) Figures 1-6 A laparoscopic gallbladder removal device includes a first sleeve 100, a sampling mechanism 200, and a clamping mechanism 300. The clamping mechanism 300 is slidably connected to the first sleeve 100 and is used to clamp the gallbladder. The sampling mechanism 200 is disposed on the first sleeve 100 and is used to remove the gallbladder from the patient's body.
[0027] Reference Figures 1-6The sampling mechanism 200 includes a second sleeve 210, a connecting rod 220, a rubber pad 230, a first guide sleeve 240, and a clamping plate 250. The second sleeve 210 is slidably connected to the first sleeve 100. The clamping plate 250 is rotatably connected to one end of the first sleeve 100. Six clamping plates 250 are provided, forming a clamping cavity between them. One end of the first sleeve 100 has a first slot 110, and one end of the second sleeve 210 has a first sliding groove 211. A first ring 400 is fitted on the first sleeve 100 and is located in the first slot 110. The clamping plate 250 has a first hole 251 through which the first ring 400 passes. The clamping plate 250 is rotatably connected to the first ring 400. A second ring 500 is slidably connected to the second sleeve 210. The second ring 500 is slidably connected to the second sleeve 210 through a first sliding groove 211. One end of the connecting rod 220 is rotatably connected to the clamping piece 250, and the other end of the connecting rod 220 is rotatably connected to the second ring 500. Six rubber pads 230 are bonded to the clamping piece 250. Each rubber pad 230 has a guide groove 231. Each rubber pad 230 corresponds to one clamping piece 250. Two first guide sleeves 240 are provided. The outer circumferential surface of the first guide sleeve 240 is fixedly connected to the inner circumferential surface of the first sleeve 100. The first guide sleeve 240 and the first sleeve 100 are coaxially arranged. The second sleeve 210 is slidably connected in the first guide sleeve 240.
[0028] During gallbladder removal, this instrument is inserted into the patient's body. After insertion, the second sleeve 210 is pushed, causing the clamping mechanism 300 to move towards the open end of the clamping piece 250. When the end of the first groove 211 reaches the second ring 500, the second sleeve 210 is pushed further, causing the ungrooved portion of the second sleeve 210 to move the second ring 500. Because the second sleeve 210 has the first groove 211, it pushes the second ring 500 downwards. The second ring 500 then rotates the connecting rod 220, causing it to push the clamping piece 250 open. This allows the clamping piece 250 to rotate and open around the first ring 400. When the outer circumferential surface of the clamping piece 250 contacts the bottom end of the first sleeve 100, the clamping mechanism 300 extends from the clamping cavity to clamp the gallbladder. 50 stops rotating; after the clamping mechanism 300 clamps the gallbladder, it pulls the second sleeve 210 to move the clamping mechanism 300 away from the opening end of the clamping piece 250. When the front end of the first slide groove 211 moves to the second ring 500, it continues to pull the second sleeve 210, causing the second sleeve 210 to pull the second ring 500 upward. The second ring 500 pulls the connecting rod 220 to rotate, causing the connecting rod 220 to tighten the clamping piece 250. At this time, the gallbladder is in the clamping cavity formed by multiple clamping pieces 250. Finally, the instrument is removed from the patient's body. Since the gallbladder is clamped by the clamping mechanism 300 and pulled into the clamping cavity formed by multiple clamping pieces 250 after removal, the gallbladder is brought out of the body by the clamping piece 250, thus eliminating the step of putting the gallbladder into the pathology bag, thereby reducing the gallbladder removal time and eliminating the need to enlarge the surgical incision, thus improving the minimally invasive and aesthetic effect. When the clamping mechanism 300 clamps the gallbladder and retracts into the clamping cavity, the clamping plates 250 retract. Since each clamping plate 250 is provided with a rubber gasket 230 and each rubber gasket 230 is provided with a guide groove 231, the side of the clamping plate 250 without a rubber gasket 230 is engaged with the rubber gasket 230 of another clamping plate 250 with a guide groove 231, thereby improving the sealing of the clamping cavity. The first guide sleeve 240 makes the sliding direction of the second sleeve 210 more accurate when it slides in the first sleeve 100, thereby improving the accuracy of the position when the second sleeve 210 drives the clamping mechanism 300 to extend.
[0029] Reference Figure 3 and Figure 4The clamping mechanism 300 includes a first gripper 310, a second gripper 320, a pressure rod 330, a first connecting rod 340, a second guide sleeve 360, and a second connecting rod 350. The pressure rod 330 is slidably connected in the second sleeve 210. The first gripper 310 and the second gripper 320 are hinged together, and both the first gripper 310 and the second gripper 320 are rotatably connected to the second sleeve 210. One end of the first connecting rod 340 is hinged to the first gripper 310. One end of the rod 340 is hinged to the pressure rod 330; one end of the second connecting rod 350 is hinged to the second clamp 320; the other end of the second connecting rod 350 is hinged to the pressure rod 330; two second guide sleeves 360 are provided; the outer circumferential surface of the second guide sleeve 360 is disposed on the inner circumferential surface of the second sleeve 210; the second guide sleeve 360 and the second sleeve 210 are coaxially arranged; the pressure rod 330 is slidably connected in the second guide sleeve 360.
[0030] When the gallbladder is grasped, the second ring 500 pushes the connecting rod 220 to rotate, causing the connecting rod 220 to push open the clamping piece 250. This causes multiple clamping pieces 250 to rotate and open around the first ring 400, and the clamping mechanism 300 extends out of the clamping cavity. At this time, the pressure rod 330 is pushed, which pushes the first connecting rod 340 and the second connecting rod 350, increasing the distance between the ends of the first connecting rod 340 and the second connecting rod 350 away from the pressure rod 330. This causes the first jaw 310 and the second jaw 320 to open. When the first jaw 310... When the first jaw 310 and the second jaw 320 reach the gallbladder position, grip the second sleeve 210 and pull the pressure rod 330 so that the first jaw 310 and the second jaw 320 can clamp the gallbladder. After clamping the gallbladder, pull the pressure rod 330 and the second sleeve 210 until the gallbladder enters the clamping cavity and is removed from the body. The second guide sleeve 360 makes the sliding direction of the pressure rod 330 more accurate when it slides in the first sleeve 100, thereby improving the positional accuracy of the pressure rod 330 when it drives the first jaw 310 and the second jaw 320 to extend.
[0031] Reference Figure 1 The first sleeve 100 is provided with a first handle 600 at the end away from the clamping piece 250, the second sleeve 210 is provided with a second handle 700 at the end away from the first clamping claw 310, and the pressure rod 330 is provided with a third handle 800 at the end away from the first connecting rod 340. The arrangement of the first handle 600, the second handle 700 and the pressure rod 330 makes it easier to slide the first sleeve 100 or the second sleeve 210 or the pressure rod 330, thereby improving the efficiency of gallbladder removal.
[0032] A method for using a laparoscopic gallbladder removal device includes the following steps: Step 1: Lift the second handle 700 and the third handle 800 upwards so that the clamping plate 250 forms a closed clamping cavity, and the first jaw 310 and the second jaw 320 approach the first sleeve 100 and move closer to each other; Step 2: Insert the instrument into the patient's body, push the third handle 800 to extend the second sleeve 210, open the clamping plate 250, and move the first clamp 310 and the second clamp 320 away from the first sleeve 100. Continue to push the third handle 800 to move the first clamp 310 and the second clamp 320 away from each other. Step 3: After the first clamp 310 and the second clamp 320 contact the gallbladder, grip the second handle 700 and pull the third handle 800 so that the first clamp 310 and the second clamp 320 clamp the gallbladder. Then pull the second handle 700 and the third handle 800 so that the gallbladder enters the clamping cavity formed by the multiple clamping plates 250. Step 4: After the multiple clamping plates 250 close, remove the instrument and take the gallbladder out of the body.
[0033] The implementation principle of the laparoscopic gallbladder removal device and its usage method in this invention is as follows: During gallbladder removal, this instrument is inserted into the patient's body. After insertion, the second sleeve 210 is pushed, causing the clamping mechanism 300 to move towards the opening end of the clamping piece 250. When the end of the first groove 211 reaches the second ring 500, the second sleeve 210 is pushed further. Due to the first groove 211 on the second sleeve 210, the second sleeve 210 pushes the second ring 500 downwards. The second ring 500 then pushes the connecting rod 220 to rotate, causing the connecting rod 220 to push the clamping piece 250 open. This causes the clamping piece 250 to rotate and open around the first ring 400. At this point, the pressure rod 330 is pushed, causing the pressure rod 330 to push the first connecting rod 340 and the second connecting rod 350 away from the pressure rod. The distance between the ends of the levers 330 increases, causing the first gripper 310 and the second gripper 320 to open. When one end of the first gripper 310 and the second gripper 320 reaches the gallbladder position, the second sleeve 210 is gripped, and the pressure lever 330 is pulled, causing the first gripper 310 and the second gripper 320 to clamp the gallbladder. After clamping the gallbladder, the pressure lever 330 and the second sleeve 210 are pulled to move away from the opening end of the clamping piece 250. When the front end of the first groove 211 moves to the second ring 500, the second sleeve 210 is pulled, causing the second sleeve 210 to pull the second ring 500 upward. The second ring 500 pulls the connecting rod 220 to rotate, causing the connecting rod 220 to tighten the clamping piece 250. At this time, the gallbladder is in the clamping cavity formed by the multiple clamping pieces 250. Finally, the instrument is removed from the patient's body.
[0034] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
