Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, in particular to compression-type gastrointestinal internal tissue removal forceps. Background Art

[0002] Endoscopic surgery and biopsy are widely used for gastrointestinal examination and treatment, particularly for sampling suspected tumors or large lesions. However, existing biopsy forceps are primarily designed for removing smaller tissue samples and are limited in effectiveness for removing larger lesions, such as large masses or tumors. Large lesions are difficult to remove through the esophagus or throat with conventional biopsy forceps, and forcible pulling can easily cause tissue fragmentation.

[0015] (3) Beneficial effects Compared with the prior art, the present invention provides a compression-type gastrointestinal tissue removal forceps, which has the following beneficial effects: 1. This compression-type gastrointestinal internal tissue removal forceps pushes the push ring to slide to the left, and the sliding column pulls the wire rope to the left, thereby driving the connecting shaft to move to the right. The forceps arm and the chuck both rotate around the left end of the forceps arm, and the two chucks approach each other to clamp the diseased tissue. Then, the rotating handle is rotated while pushing the push ring to the left, thereby driving the wire rope to twist and move to the left. The chuck clamps the diseased tissue and rotates and moves to the right. The accommodating groove can accommodate the diseased tissue, and the serrated groove increases the friction between the chuck and the diseased tissue. The cutting blade can cut the diseased tissue, making it easier to cut and separate larger diseased tissues. 2. The compression-type gastrointestinal internal tissue removal forceps rotates and moves to the right through the threaded rod, driving the sliding frame to move to the left, and driving the sealing tube to move to the left through the sliding shaft, thereby causing the right end of the tubular titanium alloy mesh to move to the left. However, the covering tube rotates and moves to the left along with the threaded rod, thereby causing the left end of the tubular titanium alloy mesh to twist and extend into the interior of the tubular titanium alloy mesh. While the tubular titanium alloy mesh covers the lesion tissue, its own twisting compresses the lesion tissue and squeezes out the moisture and air in the lesion tissue, thereby achieving the purpose of covering and compressing the lesion tissue and removing the lesion tissue with good integrity.

[0020] See also Figure 3 An annular groove 101 is provided on the inner wall of the left end of the holding handle 100, and a connecting ring 201 is fixedly installed on the right end of the rotating handle 200. The cross section of the connecting ring 201 is L-shaped, and the connecting ring 201 is rotatably connected in the annular groove 101. A finger ring 202 is fixedly installed on the left end of the rotating handle 200, and a linear groove 203 is provided on the circumferential surface of the rotating handle 200.

[0021] See also Figure 4 The rotation inhibition member 300 includes a horizontal handle 301 fixedly mounted on the circumferential surface of the left end of the gripping handle 100. A sliding hole 302 is provided at one end of the horizontal handle 301 close to the gripping handle 100. The sliding hole 302 is connected to the annular groove 101. A sliding groove 1 303 is provided inside the horizontal handle 301. The sliding groove 1 303 is connected to the sliding hole 302. A sliding groove 2 304 is provided on the circumferential surface of the horizontal handle 301. The sliding groove 2 304 is connected to the middle part of the sliding groove 1 303.

[0022] A sliding frame 305 is slidably connected within the first slide 303. A fixed post 306 is fixedly mounted between the top and bottom walls of the sliding frame 305. A pressure post 307 is fixedly mounted at the rear end of the sliding frame 305. A spring 1 308 is fixedly mounted at the rear end of the pressure post 307. A friction post 309 is fixedly mounted at the end of the spring 1 308 away from the pressure post 307. The pressure post 307 and spring 1 308 are slidably connected within the sliding hole 302. An adjustment frame 310 is slidably connected within the second slide 304. A guide slot 311 is defined within the adjustment frame 310. The middle portion of the guide slot 311 is inclined, and both ends of the guide slot 311 are arranged along the length of the adjustment frame 310. The fixed post 306 is slidably connected within the guide slot 311.

[0023] By pushing the adjustment frame 310 leftward or rightward, the adjustment frame 310 squeezes the fixed column 306 through the middle of the guide slot 311, thereby driving the sliding frame 305 to slide along the slide slot 1 303, thereby driving the pressure column 307 to move forward and backward, adjusting the compression distance of the spring 1 308. The elasticity of the spring 1 308 also adjusts the squeezing force of the friction column 309 on the connecting ring 201, thereby controlling the friction force when the rotating handle 200 rotates. This can increase the friction force of the rotating handle 200 and inhibit its rotation.

[0024] See also Figure 3 and Figure 5-Figure 6The wire assembly 500 includes a slide post 501 that is slidably connected to the rotating handle 200. A boss 502 is fixedly mounted on the circumference of the slide post 501. The boss 502 is slidably connected to the linear groove 203. A push ring 503 is sleeved on the outer side of the rotating handle 200. The boss 502 is fixedly mounted on the inner wall of the push ring 503. A wire rope 504 is fixedly mounted on the right side of the slide post 501. By pushing the push ring 503 to slide on the rotating handle 200, the connection function of the boss 502 drives the slide post 501 to slide within the rotating handle 200, and in turn drives the wire rope 504 to slide within the endoscope tube 400. When the rotating handle 200 rotates, the push ring 503, the boss 502, and the slide post 501 rotate synchronously, causing the wire rope 504 to twist. The steel wire rope 504 passes through the gripping handle 100 , the endoscope tube 400 and the clamp frame 600 , and a convex strip 505 is fixedly mounted on the circumferential surface of the tail end of the steel wire rope 504 .

[0025] See also Figure 5 A threaded groove is formed on the inner wall of the rear end of the endoscope tube 400. The clamp frame 600 includes a threaded rod 601 that is threadedly connected to the inner wall of the rear end of the endoscope tube 400. A mounting groove 602 is formed on the circumferential surface of the rear end of the threaded rod 601. A threading hole 603 is formed in the center of the threaded rod 601. The threading hole 603 is connected to the center of the mounting groove 602. An embedding groove 604 is formed on the inner wall of the threaded rod 601 located in the threading hole 603. Two slots 605 are formed on the side walls of the threaded rod 601 located in the mounting groove 602. The wire rope 504 passes through the threading hole 603, and the protrusion 505 is slidably connected to the embedding groove 604. Therefore, when the wire rope 504 is twisted, the protrusion 505 drives the threaded rod 601 to rotate. The threaded rod 601 is threadedly connected to the endoscope tube 400 through the threaded rod 601, driving the threaded rod 601 to rotate and move relative to the endoscope tube 400.

[0026] See also Figure 5-Figure 6The clamping pliers 700 include two clamp arms 701. The left ends of the two clamp arms 701 are hinged together and rotatably connected to the inner wall of the mounting slot 602. A clamp head 702 is fixedly mounted on the left end of each clamp arm 701. Each clamp head 702 has a receiving slot 703 on its opposite side. The edges of the receiving slot 703 are provided with a serrated groove 704. The left end of the clamp head 702 is provided with a cutting edge 705. The rear ends of the two clamp arms 701 are hinged to a connecting plate 706. The rear ends of the two connecting plates 706 are hinged together via a connecting shaft 707. Arched plates 708 are inserted into the two slots 605. A spring 709 is fixedly mounted between the end of the arched plate 708 and the inner wall of the slot 605. The left end of the arched plate 708 is abutted against the connecting shaft 707. The tail end of the wire rope 504 is fixedly mounted on the central circumferential surface of the connecting shaft 707. By pulling the wire rope 504, the connecting shaft 707 moves rightward, thereby causing the clamp arm 701 and the clamp head 702 to rotate around the left end of the clamp arm 701. The two clamp heads 702 move closer together to clamp the lesion tissue. The receiving groove 703 is used to accommodate the lesion tissue. The serrated groove 704 increases the friction between the clamp head 702 and the lesion tissue. The cutting edge 705 can cut the lesion tissue.

[0027] See also Figure 7-Figure 8 A avoidance groove 401 is provided on the circumferential surface of the tail end of the endoscope tube 400, and two slide rails 402 are fixedly installed on the inner wall of the tail end of the endoscope tube 400. The avoidance groove 401 and the slide rail 402 are both located on the right side of the thread groove. The right end of the slide rail 402 is flush with the right end of the avoidance groove 401, and the left end of the slide rail 402 extends to the left side of the avoidance groove 401.

[0028] See also Figure 8-Figure 9 The transmission assembly 800 includes an outer collar 801 fixedly mounted on the right end of the threaded rod 601. An inner collar 802 is rotatably connected to the outer collar 801. A square sleeve 803 is fixedly mounted on the right end of the inner collar 802. Slide bars 804 are fixedly mounted on the top and bottom of the square sleeve 803. The slide bars 804 are slidably connected to the slide rail 402. The slide bars 804 have a T-shaped cross-section and are compatible with the slide rail 402. The slide bars 804 cooperate with the slide rail 402 to guide the square sleeve 803. As the threaded rod 601 rotates and moves relative to the endoscope tube 400, the connection between the outer collar 801 and the inner collar 802 drives the square sleeve 803 to move along the length of the slide rail 402.

[0029] Rack plates 1 805 are fixedly mounted on both the front and rear sides of the square sleeve 803. Gears 806 are meshed on the opposite sides of the right ends of the two rack plates 1 805. Gears 806 are rotatably connected to the inner wall of the endoscope tube 400. Each gear 806 is meshed with a rack plate 2 807 on the side facing away from the square sleeve 803. Sliders 808 are fixedly mounted on the right ends of the two rack plates 2 807. Sliders 808 are slidably connected within the endoscope tube 400. Sliders 808 have notches at the top and bottom, through which they are slidably connected to the outside of the slide rail 402. A sliding shaft 809 is fixedly mounted on the circumference of the sliders 808. Sliders 809 are slidably connected within the avoidance groove 401. Therefore, when the square sleeve 803 moves rightward, the transmission action of rack plate 1 805, gears 806, and rack plate 2 807 drives the sliders 808 to move leftward.

[0030] See also Figure 10-11 The covering assembly 900 includes a sealing tube 901 and a covering tube 902. The sealing tube 901 is mounted on the outside of the rear end of the endoscope tube 400. The length of the sealing tube 901 is greater than twice the length of the avoidance groove 401. The covering tube 902 is fixed to the outside of the rear end of the threaded rod 601 with screws. A tubular titanium alloy mesh 903 is fixed to the outside of the left end of the sealing tube 901. The tubular titanium alloy mesh 903 is provided with multiple annular inner recesses 904 in the middle. The left end of the tubular titanium alloy mesh 903 is folded and fixed to the outer wall of the covering tube 902. The covering tube 902 is mounted on the outside of the clamp arm 701 and the connecting plate 706 to prevent the connection between the clamp arm 701 and the connecting plate 706 from getting stuck on the tubular titanium alloy mesh 903.

[0031] During use, first, the adjustment frame 310 is pushed to slide in the second slide groove 304. The middle portion of the guide groove 311 presses the fixed column 306, driving the sliding frame 305 to slide toward the slide hole 302. The pressure column 307 presses the spring 1 308, increasing the friction force of the friction column 309 on the connecting ring 201, thereby preventing the rotating handle 200 from rotating relative to the holding handle 100. Then, the push ring 503 is pushed to slide to the left, and the sliding column 501 pulls the wire rope 504 to the left, thereby driving the connecting shaft 707 to move to the right. The clamp arm 701 and the clamp head 702 both rotate around the left end of the clamp arm 701, and the two clamp heads 702 approach each other to clamp the diseased tissue. Then push the adjustment frame 310 to slide in the opposite direction to reduce the friction between the friction column 309 and the connecting ring 201, and then rotate the rotating handle 200 while pushing the pushing ring 503 to the left, thereby driving the wire rope 504 to move leftward while twisting. Because the ridge 505 is provided on the tail end of the wire rope 504, the threaded rod 601 is driven to move relative to the endoscope tube 400, so that the threaded rod 601 rotates and moves to the right, and the chuck 702 rotates and moves along with the threaded rod 601, so that the chuck 702 clamps the diseased tissue and moves to the right while rotating. Through the connection between the outer ring 801 and the inner ring 802, the square sleeve 803 is driven to move to the right, and the transmission action of the rack plate 1 805, the gear 806 and the rack plate 2 807 is coordinated to drive the sliding frame 808 to move to the left, and the sealing tube 901 is driven to move to the left through the sliding shaft 809, so that the right end of the tubular titanium alloy mesh 903 moves to the left. However, the covering tube 902 rotates and moves to the left following the threaded rod 601, so that the left end of the tubular titanium alloy mesh 903 twists and extends into the interior of the tubular titanium alloy mesh 903. Therefore, while the tubular titanium alloy mesh 903 covers the lesion tissue, its own twisting compresses the lesion tissue, squeezing out the moisture and air in the lesion tissue.
