Description

Technical Field

[0001] The invention relates to the technical field of traction forceps, in particular to a digestive endoscope-assisted traction forceps. Background Art

[0002] Endoscopic mucosal dissection is a conventional technique for treating early gastrointestinal cancer and submucosal tumors of the gastrointestinal tract. This technique requires a special electric knife to perform submucosal dissection on the lesions in the gastrointestinal tract. Because the biopsy channel of the therapeutic endoscope can only pass through one or two treatment instruments and lacks related auxiliary equipment, the treatment of gastrointestinal lesions in certain special parts is difficult, risky, and time-consuming, so traction forceps are needed for auxiliary operations.

[0003] Therefore, the traction forceps is an auxiliary device for endoscopic mucosal dissection and is widely used in endoscopic mucosal dissection. For example, the invention patent with the authorization publication number CN113925570B discloses an auxiliary traction forceps for digestive endoscopy. The traction forceps is provided with a clamping forceps, a connecting spring, a clamping frame, a clamping ball and a clamping knife. When clamping the diseased tissue, the clamping forceps are controlled to close by a No. 1 adjustment control component. During the closing process of the clamping forceps, the notched sheet on the clamping frame contacts the diseased tissue. The notched sheet increases the friction resistance of the diseased tissue during the clamping process, and the diseased tissue is squeezed with the clamping frame. The connecting spring is compressed. As the clamping proceeds, If the hardness of the diseased tissue is relatively large, the connection spring and the clamping frame can complete the clamping of the diseased tissue. If the hardness of the diseased tissue is relatively small, after the clamping frame is squeezed to a certain extent, the clamping knife cuts into the diseased tissue. During the continuous clamping, the clamping ball squeezes the diseased tissue, thereby limiting the clamping knife to prevent the clamping knife from cutting too deeply into the diseased tissue and causing damage and falling off. The clamping frame, the clamping knife and the clamping ball are distributed in a stepped manner from high to low to complete the triple clamping of the diseased tissue. However, the above method has the following defects in actual use:

[0004] 1. The triple clamping and lesion tissue clamping contact is adopted, so that in the process of clamping soft lesion tissue, the pre-contact between the limit frame, the clamping knife and the lesion tissue is easy to cause the lesion tissue to be over-extruded, cut and broken, resulting in the scattering of the lesion tissue;

[0005] 2. At the same time, it adopts a four-claw clamping method, and the clamping point is on the side of the clamp body. The clamping method is single, which is very inconvenient when clamping broken, scattered and tiny diseased tissues.

[0063] Combine the following Figures 1 to 13 The invention discloses a digestive endoscope-assisted traction forceps.

[0064] Embodiment 1:

[0065] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, in one embodiment, a digestive endoscope-assisted traction forceps includes a forceps body 100, a mounting box 300 and a clamping mechanism 400; wherein:

[0066] A clamp head 200 is installed at the bottom of the clamp body 100, and the number of the clamp body 100 and the number of the clamp head 200 are both two;

[0067] The mounting box 300 is disposed at the inner end of the pliers head 200 and is located at the opposite sides of the two pliers heads 200 , and an adjusting member 600 is also disposed on the mounting box 300 ;

[0068] The clamping mechanism 400 is disposed on the installation box 300 and is located at opposite sides of the two installation boxes 300 for clamping the diseased tissue.

[0069] It should be noted that, in the embodiment, the above-mentioned clamp body 100, clamp head 200, mounting box 300 and clamping mechanism 400 are arranged to form a traction clamp body structure capable of clamping and removing diseased tissue, so as to pull and remove the diseased tissue. Specifically, when in use, the distance between the two clamp bodies 100 is adjusted, and the two clamping mechanisms 400 are used to clamp the diseased tissue.

[0070] In a preferred embodiment, Figure 1 , Fig. 9 and Fig.11 As shown, a support rod 110 is provided on the top of the two pliers bodies 100, a handle 111 is installed at one end of the support rod 110, and a drive box 112 is provided at the other end of the support rod 110, and two miniature electric push rods 113 for driving the corresponding pliers bodies 100 are installed in the drive box 112.

[0071] It should be noted that, when in use, medical staff can control the entire traction forceps by holding the handle 111 and the support rod 110, and use the corresponding micro electric push rod 113 in the drive box 112 to control the forceps body 100, thereby completing the tissue clamping and separation operations.

[0072] It should be noted that the micro electric push rod 113 driving the pliers 100 is one driving method. The pliers 100 can also be driven by a metal rope traction method or a traditional built-in rod transmission method. The specific driving method can be adjusted according to usage requirements.

[0073] Embodiment 2:

[0074] Based on the digestive endoscopy-assisted traction forceps described in Example 1 above, Figure 2 , Figure 3 Figure 4 , Figure 5 and Figure 6 As shown, the clamping mechanism 400 includes an arc-shaped rubber plate 410 and an adjustment belt 420 installed inside the arc-shaped rubber plate 410; wherein:

[0075] Both ends of the arc-shaped rubber plate 410 are arranged at angles, and both ends of the arc-shaped rubber plate 410 are provided with hinge seats slidably connected to the installation box 300;

[0076] The two ends of the adjusting belt 420 are butt-jointed to form a U-shaped and closed conveyor belt structure, and a mesh cloth 421, an airbag cushion 422 and a convex dot cloth 423 are pasted on the outer surface of the adjusting belt 420, and a feedback mechanism 500 is also provided on the side of the arc-shaped rubber plate 410 close to the installation box 300.

[0077] It should be noted that the hinge seat is hingedly mounted at both ends of the arc-shaped rubber plate 410 and is engaged in a slot on the installation box 300 and can slide along the slot when in use.

[0078] In a preferred embodiment, Figure 3 , Figure 4 and Figure 5 As shown, the clamping mechanism 400 also includes a receiving groove 430 arranged at the lower end of the arc-shaped rubber plate 410, the receiving groove 430 is opened to the inside of the arc-shaped rubber plate 410, and a guide portion 411 and a corner portion 412 are integrally formed on one side of the receiving groove 430 of the arc-shaped rubber plate 410, respectively, the guide portion 411 and the corner portion 412 are both located on the outside of the receiving groove 430, and a medical silicone pad is also arranged at the bottom of the arc-shaped rubber plate 410.

[0079] It should be noted that, in the present embodiment, there are two clamping modes or clamping states for the diseased tissue: (1) In the first clamping mode, before clamping, the medical staff observes the size of the diseased tissue to be removed through a digestive endoscope, and then judges the hardness of the diseased tissue according to its position in the human body and its size. Subsequently, after analyzing and judging the above situation, the corresponding clamping surface on the adjustment belt 420 is selected; for example, the convex dot cloth 423 is used to clamp high-hardness diseased tissue, and the clamping is completed by the hard resistance between the convex dots; the mesh cloth 421 is used to clamp diseased tissue with a certain hardness and a shape that is easy to detach, and the friction between the meshes is used to complete stable clamping; the airbag bag 520 is used to wrap and clamp low-hardness diseased tissue. During the relative movement of the two clamp heads 200, the clamping surface corresponding to the adjustment belt 420 can be used to clamp the diseased tissue. (2) The second clamping method: if the observed lesion tissue is too small or there is accidentally scattered lesion tissue, the arc-shaped rubber plate 410 can be driven along its corner to change its clamping direction angle (adjust the arc-shaped rubber plate 410 so that it is closer to a plane to increase the contact area), so that the guide part 411 protrudes, and then the guide part 411 is placed outside the lesion tissue. At this time, the medical silicone pad is in contact with the internal tissue of the human body. During the relative movement of the two forceps heads 200, the guide part 411 is used to scoop up the lesion tissue and place it in the receiving groove 430. With the relative squeezing of the two arc-shaped rubber plates 410, the corner part 412 can be deformed to cover the receiving groove 430, thereby reducing the accidental falling of the lesion tissue inside when the forceps body 100 is taken out, thereby taking out the lesion tissue that is too small or has accidentally scattered lesions.

[0080] During the deformation and clamping process of the arc-shaped rubber plate 410 , medical staff can obtain force feedback during the clamping process based on the feedback mechanism 500 , thereby reducing the occurrence of detachment, breakage and scattering of diseased tissues due to improper clamping.

[0081] At the same time, during the clamping process, the angle of the mounting box 300 can be adjusted using the adjusting piece 600 according to the location of the diseased tissue, thereby changing the angle of the arc-shaped rubber plate 410 so that the guide portion 411 and the adjusting belt 420 can be in a relatively suitable position with the diseased tissue, facilitating the rapid auxiliary clamping operation. Compared with the traditional four-claw traction forceps, the orientation angle thereof is adjustable, the application range is wider, and the use is more convenient.

[0082] In a preferred embodiment, Figure 7 and Figure 8 As shown, two rubber rollers 424 are disposed inside the adjusting belt 420 , one end of the rubber roller 424 is connected to a driving motor, and the rubber roller 424 is rotatably connected to the inside of the arc-shaped rubber plate 410 .

[0083] It should be noted that the elastic deformation ability of the rubber roller 424 itself can ensure that after the arc-shaped rubber plate 410 is compressed and deformed, it can still provide good support and transmission effect for the adjustment belt 420, thereby ensuring normal adjustment operation of different clamping surfaces on the adjustment belt 420.

[0084] In a preferred embodiment, Figure 5 and Fig.12 As shown, the installation box 300 is slidably connected with a resistance rod 310 extending to the outside thereof, and one end of the resistance rod 310 is provided with a ball that contacts the inner side of the arc-shaped rubber plate 410 .

[0085] It should be noted that, by adopting the setting of the resistance rod 310, after it pushes the arc-shaped rubber plate 410 to move, the adjustment belt 420 on the arc-shaped rubber plate 410 can be tilted. At this time, the guide part 411 is more prominent than the adjustment belt 420, and its bottom is in a horizontal state. At this time, medical staff can use the relative movement of the two guide parts 411 to shovel accidentally scattered and tiny diseased tissues into the corresponding receiving groove 430.

[0086] In a preferred embodiment, Figure 2 and Figure 3 As shown, a circular groove 413 is formed on one side of the arc-shaped rubber plate 410 .

[0087] It should be noted that, during the process of the arc-shaped rubber plate 410 clamping the diseased tissue, when it is deformed under pressure, the gas in part of the circular groove 413 will be squeezed out. Subsequently, after being in the diseased tissue and the corresponding circular groove 413, since the arc-shaped rubber plate 410 has the ability to reset and deform, there is a slight negative pressure in the corresponding circular groove 413, thereby assisting in the adsorption of the diseased tissue and reducing its accidental scattering.

[0088] Embodiment 3:

[0089] Based on the digestive endoscope auxiliary traction forceps described in the above embodiment, Figure 3 , Figure 4 , Figure 5 , Fig.10 and Fig.11 As shown, the feedback mechanism 500 includes an air guide tube 510, an air bag package 520 and a connecting tube 530; wherein:

[0090] The air bag package 520 is sleeved on the outside of the handle 111, and the air bag package 520 is connected with the connecting tube 530 through the air guide tube 510;

[0091] The interior of the connecting tube 530 is slidably connected with a piston plate 540 , and a transmission rod 550 is installed on the outer side of the piston plate 540 . One end of the transmission rod 550 is installed to the inner side of the arc-shaped rubber plate 410 .

[0092] It should be noted that, in the present embodiment, during the process of the arc-shaped rubber plate 410 clamping the diseased tissue, its deformation will push the transmission rod 550 to move, so that it drives the piston plate 540 to introduce the gas in the connecting tube 530 into the air bag bag 520 along the air guide tube 510. Since the medical staff holds the handle 111 during the operation, the air bag bag 520 is in the palm of the medical staff's hand at this time, so the squeezing force on the diseased tissue at this time can be judged according to the expansion degree of the air bag bag 520 in the palm of the medical staff's hand, and the deformation of the arc-shaped rubber plate 410 can be observed, so that the force sense in the whole clamping process can be judged more clearly, so that in the process of clamping the diseased tissue, the phenomenon of diseased tissue being broken and scattered, and accidental detachment due to improper operation is reduced, thereby ensuring the smoothness of clamping during the operation, reducing the frequency of insertion and removal of the traction forceps after an accident, and ensuring the success rate of removing the diseased tissue during use.

[0093] In a preferred embodiment, Figure 5 As shown, two cross bars are installed on the outer side of the connecting pipe 530 , and one end of the cross bar penetrates into the interior of the arc-shaped rubber plate 410 .

[0094] It should be noted that a movable cross bar is used to support the connecting pipe 530 , and the connecting pipe 530 can slide adaptively during the movement of the arc-shaped rubber plate 410 .

[0095] Embodiment 4:

[0096] Based on the digestive endoscope auxiliary traction forceps described in the above embodiment, Figure 6 , Fig.12 and Fig.13 As shown, the adjusting member 600 includes a ratchet 610, a connecting shaft 620 and a pawl 630. The ratchet 610 is installed to the outside of the connecting shaft 620. One end of the connecting shaft 620 passes through the pliers head 200 and is fixedly connected to the outside of the mounting box 300. The pawl 630 is arranged on the outside of the ratchet 610 and is used to limit it. A reset spring is arranged on the outside of the pawl 630.

[0097] It should be noted that the connecting shaft 620 is used to connect with the installation box 300. When medical staff need to adjust the clamping angle, the ratchet 610 can be driven to rotate through the connecting shaft 620 to complete the angle adjustment of the arc rubber plate 410 on the installation box 300, and the ratchet 610 is limited by the reset spring and the pawl 630, which can effectively ensure the stability after adjustment.

[0098] Embodiment 5:

[0099] Based on the digestive endoscope auxiliary traction forceps described in the above embodiment, Figure 2 , Figure 3 , Figure 4 , Figure 5 , Fig.10 and Fig.11 As shown, a steel wire rope 700 is wound around the outer side of the connecting shaft 620 and the rubber roller 424, and a steel wire rope 700 is also installed at one end of the abutment rod 310. A slider 710 that is slidably connected to the outer side of the support rod 110 and docked with the steel wire rope 700 is provided. There are three sliders 710.

[0100] It should be noted that the corresponding steel wire rope 700 is used to control the connecting shaft 620, the rubber roller 424 and the support rod 110. During the operation, the medical staff can move the corresponding slider 710 to complete the clamping angle adjustment of the arc rubber plate 410, the adjustment and replacement of the clamping surface on different adjustment belts 420, and the clamping method adjustment of the arc rubber plate 410 using the clamping surface or the guide part 411; the corresponding steel wire rope 700 passes through the corresponding components on the traction clamp in turn and is finally placed in the support rod 110.

[0101] like Figure 1-Figure 13 As shown, the working principle and working process of the digestive endoscope-assisted traction forceps described in Examples 1 to 5 include:

[0102] When the clamp head 200 and the clamp body 100 on the traction clamp are placed in the human body to clamp the diseased tissue, the installation box 300 is used to support the arc-shaped rubber plate 410. Before clamping, the medical staff can observe the size of the diseased tissue to be removed, and then judge the hardness according to its position in the human body. Then, after analyzing and judging the above situation, the corresponding clamping surface on the adjustment belt 420 is selected to complete the clamping operation on the diseased tissue. If the observed diseased tissue is too small or there is accidentally scattered diseased tissue, the arc-shaped rubber plate 410 can be driven along its corner to change the clamping direction angle, so that the guide part 411 protrudes, and then the guide part 411 is placed On the outside of the diseased tissue, during the relative movement of the two clamp heads 200, the guide portion 411 is used to scoop up the diseased tissue and place it in the receiving groove 430. As the two arc-shaped rubber plates 410 are relatively squeezed, the angle portion 412 can be deformed to shield the receiving groove 430, thereby reducing the accidental drop of the diseased tissue inside when the clamp body 100 is taken out. The corresponding steel wire rope 700 is used to control the connecting shaft 620, the rubber roller 424 and the support rod 110. During the operation, the medical staff can move the corresponding slider 710 to complete the adjustment of the clamping angle of the arc-shaped rubber plate 410 and the adjustment of the clamping surface on the different adjustment belts 420. The clamping mode of the curved rubber plate 410 is changed to be clamped by the clamping surface or the guide part 411. During the deformation and clamping process of the curved rubber plate 410, the deformation will push the transmission rod 550 to move, so that it drives the piston plate 540 to guide the gas in the connecting tube 530 into the air bag bag 520 along the air guide tube 510. Since the medical staff holds the handle 111 during the operation, the air bag bag 520 is in the palm of the medical staff at this time, so the squeezing force on the diseased tissue at this time can be judged according to the expansion degree of the air bag bag 520 in the palm, and the deformation of the curved rubber plate 410 can be observed to judge the force sense in the whole clamping process. The segmentation is clearer, thereby reducing the occurrence of broken and scattered diseased tissues and accidental detachment due to improper operation during the clamping of the diseased tissue, thereby ensuring the smoothness of the clamping during the operation and reducing the frequency of inserting and removing the traction forceps after an accident. During the clamping process, the angle of the mounting box 300 can be adjusted by rotating the connecting shaft 620 according to the position of the diseased tissue, thereby changing the angle of the arc-shaped rubber plate 410, so that the guide part 411 and the adjustment belt 420 can be in a relatively suitable position with the diseased tissue, which is convenient for the rapid auxiliary clamping operation. Compared with the traditional four-claw traction forceps, the direction angle is adjustable and the scope of use is wider.
