Description

Technical field:

[0001] The utility model relates to the field of surgical instruments, in particular to a surgical device used in conjunction with an endoscope mucosal suction sleeve. Background technology:

[0002] At present, endoscopes are medical instruments used to examine human organs and perform surgery on diseased tissues. During endoscopic examinations and surgeries, a transparent mucosal suction sleeve is placed on the top of the endoscope, and then a snare is passed through the endoscope's own channel. The snare is used to extend the transparent mucosal suction sleeve to cut the diseased tissue in the diseased area, and then the cut diseased tissue is sucked into the nearby transparent mucosal suction sleeve through the endoscope's adsorption capacity to complete the surgery.

[0003] In actual applications, it was found that some diseased tissues are too large and have different shapes, while the commonly used transparent mucosal suction cuff is an integrated cylindrical shape with a single structure. Therefore, the interior and shape of the transparent mucosal suction cuff need to match it to accommodate the diseased tissue; secondly, the snare passing through the endoscope channel must extend out of the mouth of the transparent mucosal suction cuff. Due to the narrow space of the mouth, the "loop" at the end of the snare is too small, and it is not suitable for diseased tissues that are too large. The "loop" of the snare is also called a ring.

[0004] In view of the above findings, the surgical method was changed and the "loop" of the snare was put on the outer wall of the transparent mucosal suction cuff to avoid the problem of the "loop" of the snare being too small. The "loop" of the snare was then removed from the transparent mucosal suction cuff during the operation. However, there is still a lack of corresponding technology for medical instruments suitable for improved surgery. Utility model content:

[0050] The middle section of the push rod 4 passes through the sleeve 5 on the other side of the endoscope, and the front section of the push rod 4 movably hooks the ring of the snare 2. The push rod 4 follows the endoscope into the patient's body and can move in the corresponding sleeve 5, and then operate the push rod 4 to remove the ring of the endoscope from the outside of the transparent mucosal suction sleeve 1.

[0051] The sleeve 5 is formed by combining two sleeve components 5.1. Figure 4 As shown, in order to prevent the middle end of the push rod 4 and the ring of the snare 2 from being unable to penetrate into the sleeve 5 from any end of the sleeve 5, the sleeve 5 is designed to be matched with two sleeve components 5.1 to reduce interference and improve ease of use. The adjacent side walls of the two sleeve components 5.1 are respectively provided with mutually matching protrusions 8 and grooves 9. When the two sleeve components 5.1 are matched, they can be positioned by splicing the protrusions 8 and grooves 9 between each other to avoid misalignment.

[0052] Two parallel cuts are made along the two ends of the adhesive tape 6 toward the center, and the two ends of the adhesive tape 6 are divided into three parts, and any part of the two ends of the adhesive tape 6 is adhered to the external hanger 3, such as Figure 3 As shown, when the sleeve 5 is composed of two sleeve components 5.1, the two sleeve components 5.1 are firstly wrapped and bonded together by any part of the two ends of the tape 6, and then the remaining parts of the two ends of the tape 6 are bonded and fixed to the endoscope.

[0053] The card slot 7 is also provided with an inner concave hole 10, and the front section of the push rod device 4 is movably embedded in the inner concave hole 10, so as to avoid the front section of the push rod device 4 from bulging outward as much as possible, thereby reducing the degree of scratch damage to the patient during the process of entering the patient's body.

[0054] The push rod device 4 includes a shaft 11 and a pliers head 12 integrally formed at the end of the shaft 11; the pliers head 12 is annular and has an opening; the shaft 11 is the middle section of the push rod device 4, the pliers head 12 is the front section of the push rod device 4, and the pliers head 12 is put on the ring of the snare 2 by using the opening; the push rod device 4 can be made of polyethylene material and is soft.

[0055] The transparent mucosal suction sleeve 1 is in the shape of a trumpet with a wide top and a narrow bottom, or in the shape of a lantern with narrow ends and a wide middle, such as Figure 1 , 3 , 5, 10 show a trumpet-shaped transparent mucosal suction sleeve 1, wherein Fig.10 Medium transparent mucosal suction sleeve 1 Figure 1 , 3 , 5. The diameter of the transparent mucosal suction sleeve 1 is wide, such as Figures 11 to 15 Shown is a lantern-shaped transparent mucosal suction sleeve 1, Fig.12 Medium transparent mucosal suction sleeve 1 Fig.11 The diameter of the transparent mucosal suction sleeve 1 is narrow. Fig.13 Medium transparent mucosa suction sleeve 1 side wall ratio Fig.11 The side wall of the transparent mucosal suction sleeve 1 converges, Fig.14 The transparent mucosa suction sleeve 1 has a ratio of the upper and lower ends Fig.11 The upper and lower ends of the transparent mucosal suction sleeve 1 are longer in the axial direction. Fig.15 Middle transparent mucosa suction sleeve 1 upper end ratio Fig.11 The upper end of the transparent mucosal suction sleeve 1 is inclined, and one side wall is also convergent, and various shapes such as trumpet-shaped and lantern-shaped are designed to divide the volume to meet the use requirements.

[0056] Working principle:

[0057] The novel technology of the present invention uses adhesive tape 6 to stick the sleeve 5 to the endoscope, so that the external hanger 3 is fixed on the endoscope, and the push rod device 4 moves on the sleeve 5 of the external hanger 3 through the rod body 11, so that the push rod device 4 is attached to the side of the endoscope, so that the clamp head 12 of the external hanger 3 can follow the endoscope into the patient's body, and the push and pull actions of the clamp head 12 can be used to remove the ring of the snare 2 from the transparent mucosa during surgery. During surgery, when the ring of the snare 2 has been wrapped around the diseased tissue, the push rod device 4 needs to be removed, and the opening of the clamp head 12 can be used to detach from the ring of the snare 2, or the electric heating resection method of the snare 2 can be used to cut off the clamp head 12 and detach it, so as to meet the operation of the surgery. At the same time, the push rod device 4 has a simple structure and can be made into a disposable product to reduce costs.

[0058] Embodiment 2:

[0059] like Figure 5-Figure 9 As shown, a surgical device used in conjunction with an endoscopic mucosal suction sleeve, the push rod device 4 includes an operating component 13, a connecting tube 14, and a hook wire component 15;

[0060] The ends of the operating assembly 13, the connecting pipe 14 and the hook wire assembly 15 are connected in sequence;

[0061] The operating assembly 13 includes a cylindrical fixing assembly 16, a pull rod 17, and a tension spring 18. One end of the pull rod 17 is slidably inserted into one end of the cylindrical fixing assembly 16 and fixed to one end of the tension spring 18. The tension spring 18 is placed in the cylindrical fixing assembly 16, and the other end is fixed to the inner wall of the cylindrical fixing assembly 16. Pulling the pull rod 17 outward from the cylindrical fixing assembly 16 can drive the tension spring 18 to extend, and retracting the tension spring 18 can drive the pull rod 17 to reset.

[0062] The cylindrical fixing assembly 16 is composed of a cylinder 19 and a hand-held handle sleeve 20 integrally fixed on both sides of the cylinder 19;

[0063] A support rod 21 is fixed at the end of the pull rod 17, and a slide groove 22 is provided on the side wall of the cylinder 19 corresponding to the support rod 21. The two ends of the support rod 21 are slidably placed in the slide groove 22. The movement of the pull rod 17 drives the support rod 21 to slide in the slide groove 22, which has the effect of stabilizing the movement, and the length of the slide groove 22 limits the travel of the pull rod 17.

[0064] The hook wire assembly 15 includes a base 23, a semi-circular fixing member 24, and a semi-circular movable member 25. The semi-circular fixing member 24 and the semi-circular movable member 25 are matched to form a whole circle. The end of the semi-circular fixing member 24 is fixed to one end of the base 23. A cavity 26 is provided in the base 23. The cavity 26 is connected to both ends of the base 23. The end of the semi-circular movable member 25 slides into the cavity 26. The semi-circular movable member 25 moves in the cavity 26 of the base 23 and can be temporarily separated from the semi-circular fixing member 24, so that a gap appears in the whole circle formed by the matching of the semi-circular fixing member 24 and the semi-circular movable member 25.

[0065] The hook wire assembly 15 further includes a spring 27, which is placed in the cavity 26, with one end of the spring 27 abutting against the end of the base 23, and the other end of the spring 27 abutting against the end of the semi-annular movable member 25. The spring 27 applies force to the semi-annular movable member 25, and pushes the semi-annular movable member 25 to align with the semi-annular fixed member 24.

[0066] A traction line 28 passes through the connecting pipe 14. One end of the traction line 28 is fixed to the pull rod 17, and the other end is fixed to the end of the semi-annular movable part 25. Pulling the pull rod 17 drives the semi-annular movable part 25 to move through the traction line 28, and controls the semi-annular fixed part 24 and the semi-annular movable part 25 to form a gap in the whole circle, so as to realize the opening of the semi-annular movable part 25.

[0067] The connecting pipe 14 is the middle section of the push rod device 4 , and the hook wire assembly 15 is the front section of the push rod device 4 .

[0068] Working principle:

[0069] like Figure 5-7 As shown, the cylindrical fixing component 16 is held in the hand, wherein the index finger and the middle finger are inserted into the hand-held handle sleeve 20, and the thumb can be inserted into the ring sleeve at the end of the pull rod 17. The pull rod 17 is pulled toward the outside of the cylinder 19 of the cylindrical fixing component 16 by the thumb, and the traction line 28 drives the semi-annular movable part 25 to move, and the semi-annular movable part 25 of the hook line component 15 opens, and the force of the thumb is released, and the tension spring 18 drives the pull rod 17 to return to its original position, and the spring 27 pushes the semi-annular movable part 25 to return to its original position.

[0070] First, the semi-circular movable part 25 is opened and then closed, and the full circle formed by the semi-circular fixed part 24 and the semi-circular movable part 25 is hooked on the ring of the snare 2, and the connecting tube 14 and the hook wire assembly 15 follow the soft endoscope into the lesion area. When removing the ring, the connecting tube 14 and the hook wire assembly 15 are pushed by the operating assembly 13, so that the semi-circular fixed part 24 and the semi-circular movable part 25 remove the ring, and then the semi-circular movable part 25 is opened, and the hook wire assembly 15 is separated from the ring by the gap; or it can be used with the snare 2, and then separated after the ring is hooked on the lesion tissue. The connecting tube 14 can be made of polyethylene material, which is soft.

[0071] The novel device comprises structures such as an operating component 13, a connecting tube 14, and a hook wire component 15. By holding the operating component 13, the hook wire component 15 can be opened and closed to realize the removal and disengagement control of the end ring of the snare 2. The connecting tube 14 is made of medical plastic, which has a certain hardness and can maintain toughness. Compared with the hard straight tube of the existing medical forceps, it can be used to bend with the soft endoscope and can be reused.

[0072] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
