Description

Technical Field

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

[0002] Gallstones, also known as cholelithiasis, refer to stone diseases that form in the biliary system, including the gallbladder or bile duct. Biliary tract infection is a common condition and can be divided into two types: cholecystitis and cholangitis, depending on the location of the disease. After the stones form in the gallbladder, they will irritate the gallbladder mucosa and may cause chronic gallbladder inflammation. When the stones are impacted in the gallbladder neck or cystic duct, they may also cause secondary infection, leading to acute gallbladder inflammation. Long-term irritation of the gallbladder mucosa by stones may also lead to gallbladder cancer. It has been reported that the incidence of gallbladder cancer can reach 1% to 2%.

[0003] When performing minimally invasive surgery for gallstones, three small incisions of 2 to 3 cm are usually made in the abdomen. The surgical tool then pre-cuts a small opening in the outer wall of the gallbladder, which can be covered with medical gauze to prevent bile from contaminating the abdominal cavity and to prevent saline flushing from flowing into the abdominal cavity during choledochoscopy and stone removal. However, if the gallstones in the patient's gallbladder are too large, when using a removal tool to remove the gallstones from the gallbladder, the incision on the outer wall of the gallbladder is smaller than the size of the gallstones, and the doctor usually needs to change the cutting tool and chop the gallstones into pieces before removing them, which increases the operation time. If the doctor attempts to directly remove the oversized gallstones in order to save time or due to a misjudgment, the incision on the outer wall of the gallbladder may be torn. This uneven torn incision not only causes secondary damage to the gallbladder, but also may affect the suturing of the incision, which is not conducive to the patient's postoperative recovery. Therefore, the present invention provides a gallstone surgery stone removal device to meet this demand. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a gallstone surgical stone removal device to solve the technical problem that for gallstones larger than the incision on the outer wall of the gallbladder, if no cutting tool is used, the doctor's operation time may be increased, or the incision on the outer wall of the gallbladder may be torn when trying to remove them directly, thereby causing secondary damage to the gallbladder, and the torn wound is not conducive to postoperative recovery.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] A gallstone surgical stone removal device comprises a minimally invasive channel, a puncture needle tube is inserted into the minimally invasive channel, a support tube is inserted into the puncture needle tube, one end of the support tube is fixedly connected to a handle, the other end of the support tube is fixedly connected to an expansion port, a fixing plate is fixedly connected to the outer wall of the support tube, three sliding blocks are fixedly connected to the inner wall of the expansion port, two support frames are fixedly connected to the top outer wall of the handle, and a through hole is opened on the handle; a clamping assembly, the clamping assembly is used to clamp gallstones in the patient's gallbladder, the clamping assembly is respectively connected to the handle; the cutting assembly is used to chop up larger gallstones in the patient's gallbladder, the cutting assembly is respectively connected to the expansion port and the handle.

[0007] Optionally, the clamping assembly includes a pressure handle screwed to one end of the two support frames, one end of the pressure handle is screwed to a linkage column, the other end of the pressure handle is fixedly connected to a first elastic plate, one end of the linkage column is screwed to a clamping tube, three avoidance grooves are opened on the outer wall of the clamping tube, and the other end of the clamping tube is fixedly connected to three clamping petals.

[0008] Optionally, a rubber pad is fixedly connected to the inner wall of the clamping flap, a segmented groove is provided on the rubber pad, a first sliding groove is provided on the outer wall of the clamping flap, and a second sliding groove is provided on the inner wall of the clamping flap.

[0009] Optionally, the cutting assembly includes a second elastic plate fixedly connected to the outer wall of the bottom of the handle, the other end of the second elastic plate is fixedly connected to a pressing plate, and one end of the pressing plate is fixedly connected to a sliding ring.

[0010] Optionally, support columns are symmetrically fixedly connected to both sides of the sliding ring, springs are sleeved on the support columns, the other end of the support columns is fixedly connected to a useful sliding plate, and one end of the sliding plate is fixedly connected to three traction ropes.

[0011] Optionally, one end of the traction rope is fixedly connected to a hook, the hook is hung with a semicircular buckle, the semicircular buckle is rotatably connected to a linkage handle, and the linkage handle is rotatably connected to a linkage plate.

[0012] Optionally, a C-shaped buckle is fixedly connected to the top outer wall of the linkage plate, a third elastic plate is fixedly connected to the bottom outer wall of the linkage plate, and one end of the linkage plate is rotatably connected to a control plate.

[0013] Optionally, a fixing ring is clamped on the C-shaped buckle, and three fixing columns are fixedly connected to the outer wall of the fixing ring.

[0014] Optionally, three clamping plates and a limit block are fixedly connected to an outer wall on one side of the control panel, a sliding column is fixedly connected to an outer wall on the other side of the control panel, and a sliding ball is fixedly connected to one end of the sliding column.

[0015] Optionally, a blade is clamped on the control board.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above scheme, by providing a cutting assembly, the doctor can cut up larger gallstones in the patient's gallbladder. For gallstones that are larger than the incision on the outer wall of the gallbladder, if a cutting tool is not used, the doctor's operation time may be increased, or the incision on the outer wall of the gallbladder may be torn when attempting to remove it directly, causing secondary damage to the gallbladder. The torn wound is also not conducive to postoperative recovery. In this case, the doctor can use the cutting assembly to cut the oversized gallstones during the clamping process, avoiding the need to switch from the clamping tool to the cutting tool, thereby shortening the operation time.

[0018] The clamping assembly allows doctors to remove gallstones from the patient's gallbladder. The rubber pad on the clamping assembly provides a stable grip for irregularly shaped gallstones. During the procedure, doctors can control the clamping assembly to clamp or release the gallstone simply by tightening or loosening their grip, making the operation simple and convenient. This design not only improves the doctor's comfort during surgery but also enhances the stability of the clamping assembly when handling gallstones of varying sizes and shapes.

[0019] By setting a spring, a support column, a pressing plate and a second elastic plate in the cutting assembly. When the doctor uses the clamping assembly to clamp the gallstones in the gallbladder, if he encounters some overly large and irregular gallstones, the doctor can operate by pressing the pressing plate. This action will drive the support column to pull the sliding plate and tighten the traction rope, thereby extending the blade to cut the gallstones. After the cutting is completed, the elastic action of the spring and the second elastic plate will reset the pressing plate. This structural design makes the operation of extending the blade out of the expansion port simpler and more convenient, and ensures that the extension distance of each blade is consistent, realizing the synchronous extension of the blade and improving the safety of the operation.

[0020] By arranging a linkage plate, a control plate, a third elastic plate, a sliding column, and a sliding ball within the cutting assembly, the doctor can control the extension of the blade by pressing the plate to facilitate the cutting of gallstones. After the cutting is completed, the elastic action of the third elastic plate automatically returns the blade to its original position. This retractable blade design ensures the safety of the device. At the same time, the sliding column and sliding ball slide on the first sliding groove, allowing the angle of blade extension to be adjusted as the angle of the clamping flap changes, thereby adapting to the cutting needs of gallstones of different sizes.

[0021] By arranging a clamping plate and a stop block in the cutting assembly, wherein the clamping plate and the stop block form an integrated structure with the control panel, this design allows the blade to be quickly clipped onto the control panel, making it easy to install and remove the blade.

The support tube 3 is a metal pipe in the shape of a hollow cylinder. The handle 4 is fixedly connected to one end of the support tube 3. The fixing plate 301 is fixedly connected to the outer wall of the support tube 3 near the handle 4. The fixing plate 301 is a metal circular plate with circular holes on both sides. The handle 4 is an elliptical cylinder made of plastic material. A through hole 401 is provided on the top outer wall of the end of the handle 4 close to the support tube 3. The through hole 401 is funnel-shaped. The other end of the support tube 3 is fixedly connected with an expansion port 302. The expansion port 302 is trumpet-shaped and is made of metal. The three sliding blocks are distributed in a circular array and fixedly connected to the inner wall of the expansion port 302. The sliding blocks are rectangular blocks made of metal.

[0041] like Figures 1 to 9As shown, the clamping assembly includes a pressing handle 5 screwed to one end of the two support frames 402, one end of the pressing handle 5 is screwed with a linkage column 501, the other end of the pressing handle 5 is fixedly connected to the first elastic plate 404, one end of the linkage column 501 is screwed with a clamping tube 502, three avoidance grooves 607 are provided on the outer wall of the clamping tube 502, the other end of the clamping tube 502 is fixedly connected with three clamping petals 503, the inner wall of the clamping petal 503 is fixedly connected with a rubber pad 505, the rubber pad 505 is provided with a segmented groove, the outer wall of the clamping petal 503 is provided with a first sliding groove 504, and the inner wall of the clamping petal 503 is provided with a second sliding groove 506.

[0042] Specifically, the pressing handle 5 is screwed to one end of the two support frames 402 by screws. The pressing handle 5 is a spoon-shaped metal plate. The linkage column 501 is screwed to one end of the pressing handle 5 by screws. The first elastic plate 404 is fixedly connected to the other end of the pressing handle 5. The linkage column 501 is a metal cylinder. The first elastic plate 404 is in a "C" shape and is made of plastic. The other end of the first elastic plate 404 is fixedly connected to the outer wall of one end of the handle 4. After pressing the pressing handle 5, the pressing handle 5 will be reset under the elastic action of the first elastic plate 404, and the clamping tube 502 is screwed to the other end of the linkage column 501 by screws.

[0043] The clamping tube 502 is divided into two parts. The clamping tube 502 extends into the interior of the support tube 3. One part is a metal cylinder and the other part is in the shape of a trumpet that expands outward. Three avoidance grooves 607 are distributed in a circular array on the outer wall of the end of the clamping tube 502 that is in the trumpet shape. The avoidance grooves 607 are in the shape of a straight slot as a whole. The three clamping petals 503 are distributed in a circular array and are fixedly connected to the end of the clamping tube 502 that is in the trumpet shape. The overall outline of the clamping petal 503 is fan-shaped and is divided into two parts. In the initial state, the part close to the clamping tube 502 expands outward and fits the inner wall of the expansion mouth 302, while the other part is parallel to the metal cylinder of the clamping tube 502, and both parts have a curved transition, which makes it convenient to clamp gallstones.

[0044] The rubber pad 505 is fixedly connected to the inner wall of the end of the clamping flap 503 away from the clamping tube 502. The rubber pad 505 is made of rubber, and a number of segmented grooves are provided on the outer wall of the rubber pad 505 away from the clamping flap 503. The setting of the segmented grooves can more firmly clamp gallstones of different sizes and shapes. The first sliding groove 504 and the second sliding groove 506 are respectively provided on the outer wall and the inner wall of the clamping flap 503. The first sliding groove 504 is in a quadrilateral shape, and its inner wall fits the outer wall contour of the sliding block. The second sliding groove 506 is circular, and the diameter of the circle is slightly larger than the diameter of the sliding ball 902, so that the sliding ball 902 can slide on the second sliding groove 506.

[0045] With the arrangement of the above structure, when the doctor uses the present device, he uses the puncture needle tube 2 to insert the support tube 3 into the patient's body, and uses the endoscope to extend into the patient's gallbladder to check the position of the gallstones. When the gallstones are small, the present device can be directly used to clamp the smaller gallstones out of the gallbladder and place them in the prepared specimen bag. When clamping, the doctor only needs to press the end of the pressure handle 5 close to the first elastic plate 404. Under the action of the lever principle, the other end of the pressure handle 5 will be lifted, driving the linkage column 501 to move in the direction of the lifting of the pressure handle 5. At the same time, the linkage column 501 will drive the clamping tube 502 to move in the same direction. At this time, the clamping flap 503 will slide on the inner wall of the expansion opening 302, and the sliding block fixedly connected to the inner wall of the expansion opening 302 will be on the outer wall of the clamping flap 503. The clamping flap 503 can be limited by sliding on the first sliding groove 504 opened on the upper surface to prevent the clamping flap 503 from shaking during the process of clamping gallstones, which affects the doctor's subsequent surgery. At this time, the segmented grooves on the rubber pad 505 can adapt to the different sizes and shapes of gallstones and can clamp the gallstones very stably. After each time the gallstones are taken out of the gallbladder, the pressing handle 5 is released and the pressing handle 5 is reset under the elastic action of the first elastic plate 404, which will drive the linkage column 501 and the clamping tube 502 to move in the direction of resetting the pressing handle 5, and the clamping flap 503 will be reset under the drive of the clamping tube 502 and the action of its own elasticity. The above structural setting can improve the comfort of doctors during surgery and improve the stability of clamping gallstones of different sizes and shapes.

The support column 602 is a metal cylinder, and the support column 602 passes through the circular hole opened on the fixed plate 301 mentioned above. The three traction ropes 605 are distributed in a circular array and fixedly connected to the outer wall of the sliding plate 604 away from the fixed plate 301. The traction rope 605 passes through the avoidance groove 607 mentioned above, and the hook 606 is fixedly connected to the other end of the traction rope 605.

[0048] Specifically, the hook 606 is hung on one side of the semicircular buckle 804, and the side of the semicircular buckle 804 away from the hook 606 is rotatably connected to one end of the linkage handle 803.

The clamping plate 904 is a plastic straight plate, and one end has a triangular protrusion. The clamping plate 904 cooperates with the limit block 903 to facilitate the clipping of the blade 905 to the control board 9. The middle parts of the above-mentioned pressing handle 5, pressing plate 6, first elastic plate 404, second elastic plate 403, third elastic plate 802 and linkage handle 803 are all provided with lightweight grooves. The setting of the lightweight groove can not only save production materials, but also reduce the weight of the device, thereby reducing the doctor's hand fatigue when holding the device for a long time during surgery.

[0050] By the arrangement of the above structure, when the doctor uses an endoscope to insert into the patient's gallbladder to check for gallstones, if the gallstones are found to be too large, the doctor can first use the clamping assembly to clamp the gallstones, and the rubber pad 505 can cooperate with the clamping flap 503 to firmly clamp the gallstones. At this time, the pressing plate 6 can be pressed with a finger, and the second elastic plate 403 will be deformed in the direction of its bending under the force, and then the pressing plate 6 drives the sliding ring 601 to move in the direction of the finger, and the support column 602 on the sliding ring 601 slides on the circular hole on the fixed plate 301 and drives the sliding plate 604 to move in the direction of displacement of the sliding plate 604. At this time, the sliding plate 604 will compress the spring 603, and the spring 603 will deform in the direction of its bending. At this time, the sliding plate 604 will tighten the three traction ropes 605 at the same time. During the tightening process of the traction rope 605, the linkage handle 803 is pulled to drive the linkage plate 8 to rotate on the fixed ring 7. During the rotation process, the linkage plate 8 will cause the control plate 5, and the supporting column 602 drives the sliding plate 604 to relax the traction rope 605, and the linkage plate 8 and the control plate 9 are reset under the elastic action of the third elastic plate 802, so that the blade 905 is retracted.

[0051] The working principle of the technical solution provided by the present invention is as follows:

[0052] When the doctor uses this device, first, the support tube 3 is placed into the patient's body using the puncture needle tube 2, and then inserted into the patient's gallbladder through an endoscope to check the position of the gallstones. For smaller gallstones, the doctor can directly use this device to clamp them out of the gallbladder and place them in a pre-prepared specimen bag. During the clamping process, the doctor only needs to press the pressure handle 5 near one end of the first elastic plate 404. Using the lever principle, the other end of the pressure handle 5 will lift, driving the linkage column 501 to move in the direction of lifting. At the same time, the linkage column 501 will also drive the clamping tube 502 to move in the same direction. At this time, the clamping flap 503 will slide on the inner wall of the expansion port 302, and the sliding block fixedly connected on the inner wall of the expansion port 302 will slide on the first sliding groove 504 on the outer wall of the clamping flap 503, limiting the clamping flap 503 to prevent it from shaking when clamping gallstones, thereby affecting the operation. The segmented groove on the rubber pad 505 can adapt to gallstones of different sizes and shapes, ensuring stable clamping. After each gallstone is removed, the pressure handle 5 is released and reset under the elastic action of the first elastic plate 404. The linkage column 501 and the clamping tube 502 also move in the direction of the pressure handle 5 reset. The clamping flap 503 is reset under the drive of the clamping tube 502 and the elastic action of the clamping flap 503. These structural designs improve the comfort of the operation and the stability of clamping different gallstones.

[0053] If the doctor finds that the gallstone is too large, he can first clamp it with a clamping assembly. The cooperation between the rubber pad 505 and the clamping flap 503 can firmly clamp the gallstone. At this time, the doctor can press the pressing plate 6, and the second elastic plate 403 will deform along its bending direction after being stressed, and the pressing plate 6 will drive the sliding ring 601 to move along the finger direction. The support column 602 on the sliding ring 601 slides on the circular hole on the fixed plate 301, driving the sliding plate 604 to move in the same direction and compress the spring 603. After the spring 603 is deformed, the sliding plate 604 tightens the three traction cables 605, and the traction cables 605 pull the linkage handle 803, causing the linkage plate 8 to rotate on the fixed ring 7. When the linkage plate 8 rotates, the control plate 9 is displaced, forcing the third elastic plate 802 to deform, and the control plate 9 drives the blade 905 clamped on its outer wall to move. The sliding ball 902 slides on the inner wall of the second sliding groove 506, rests on the inner wall of the clamping flap 503, and cooperates with the sliding column 901 to limit the control plate 9, ensuring that the blade 905 is consistent with the clamping flap 503 extension direction, and does not exceed the clamping flap 503 when stretched to the maximum extent, so that the gallstones of different sizes can be cut better, while preventing the blade 905 from accidentally injuring the inner wall of the gallbladder. After the cutting is completed, release your fingers, the pressing plate 6 will reset under the elastic action of the second elastic plate 403 and the spring 603, the support column 602 pushes the sliding plate 604 to relax the traction rope 605, the linkage plate 8 and the control plate 9 reset under the elastic action of the third elastic plate 802, thereby retracting the blade 905, and in the repeated extension and retraction of the blade 905, it is achieved that larger stones are cut, and after the cutting is completed, the gallstones can be taken out.
