[0101] As described in the background section, lesions are typically located using the positioning function of an endoscope. Biopsy forceps are then inserted through the endoscope's channel to reach the lesion tissue, which is then grasped. During this grasping process, the operator's experience and feel are generally relied upon, which requires a high level of skill. Furthermore, it is difficult to guarantee that the operator can grasp the tissue well every time, especially in complex or confined locations such as the gastrointestinal tract or urinary tract, where the positioning of the endoscopic positioning device is even more difficult. Slight carelessness can lead to positioning deviations, resulting in inaccurate grasping of the biopsy forceps. The operator may need to adjust the position of the biopsy forceps multiple times, making the lesion tissue grasping process complex and time-consuming.

[0102] To address the aforementioned technical problems, this application proposes a biopsy forceps, comprising a handle, a slider, a push rod, an outer tube, and a forceps head. A first channel is formed within the handle, extending axially through it. A sliding hole is formed on the side of the handle, communicating with the first channel. The slider is inserted into the sliding hole and slidably connected to the handle. The push rod is inserted into the first channel, one end of which is fixedly connected to the slider, and the other end of which is outside the first channel. The outer tube is fitted onto the push rod and fixedly connected to the handle. The forceps head includes a first forceps body and a second forceps body. The first and second forceps bodies are rotatably connected to the outer tube and slidably connected to the push rod. When the slider slides along the sliding hole, it drives the first and second forceps bodies to rotate relative to the outer tube via the push rod, causing them to open or close. This allows the forceps head to grasp lesion tissue, with a simple grasping action, achieving efficient grasping, and is easy to operate with low technical requirements for the operator. A third channel is formed on the push rod, which runs through the push rod axially. One end of the third channel is connected to the first channel, and the other end of the third channel is located at the forceps head. This allows positioning and display structures such as confocal microscope probes and ultrasound probes to pass through the first and third channels to reach the forceps head, enabling more precise positioning of lesions. The position and gripping angle of the forceps head can be adjusted according to the positioning and display results, achieving precise gripping, high gripping efficiency, and good gripping effect.

[0103] To make the objectives, implementation methods and advantages of this application clearer, the exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this application.

Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0106] References 1 and 2 Figure 2 This application provides a biopsy forceps 1. The biopsy forceps 1 can be inserted into the lesion area inside the human body through the endoscopic channel of an endoscope, and then the lesion tissue can be grasped.

[0107] The biopsy forceps 1 includes a handle 11. The handle 11 includes a first end 1111. The handle 11 includes a second end 1112. The first end 1111 and the second end 1112 are arranged opposite to each other in the axial direction of the handle.

[0108] A first channel 112 is formed within the handle 11. The first channel 112 extends through the handle axially. The first channel 112 is used for a positioning and display structure, such as a probe, to pass through. The positioning and display structure can be a confocal microscopy probe. The positioning and display structure can be an ultrasonic probe. The positioning and display structure can also be other structures. The handle can be made of materials such as plastic, and the handle can be injection molded.

[0109] A sliding hole 1131 is formed on the handle 11. The sliding hole 1131 is located on the side of the handle. The sliding hole communicates with the first channel. The sliding hole 1131 can be an elongated hole. The sliding hole can extend along the axial direction of the handle.

[0110] The biopsy forceps 1 includes a slider 12. The slider 12 is inserted into a sliding hole. The slider is slidably connected to the handle.

[0111] refer to Figure 3 and Figure 4 The biopsy forceps 1 includes a push rod 13. The push rod 13 is inserted into the first channel 112. One end of the push rod 13 is fixedly connected to the slider, and the other end of the push rod is located outside the first channel.

[0112] The push rod 13 includes a first end 1311 and a second end 1312. The first and second ends of the push rod are positioned opposite each other in the axial direction of the push rod. The first end of the push rod is fixedly connected to the slider. The second end of the push rod is located outside the first channel.

[0113] refer to Figure 9 and Figure 10 The biopsy forceps 1 includes an outer tube 14. The outer tube 14 is fitted onto the push rod. The outer tube is fixedly connected to the handle.

[0114] The outer tube 14 includes a first end 1411. The outer tube also includes a second end 1412. The first end and the second end of the outer tube are arranged opposite each other in the axial direction of the outer tube.

[0115] A second channel 142 is formed inside the outer tube 14. The second channel 142 extends through the outer tube axially. The outer tube 14 is sleeved on the push rod through the second channel. The first end of the outer tube is fixedly connected to the handle.

[0116] The biopsy forceps 1 includes a forceps head 15. The forceps head 15 is located at the second end of the push rod. The forceps head is located at the second end of the outer tube.

[0117] The pliers head 15 is connected to the outer tube. The pliers head is also connected to the push rod. When the slider slides along the sliding hole, the slider drives the pliers head to open or close via the push rod.

[0118] The pliers head 15 includes a first pliers body 151. The pliers head 15 includes a second pliers body 152. The first pliers body is rotatably connected to the outer tube. The second pliers body is rotatably connected to the outer tube. The first pliers body is slidably connected to the push rod. The second pliers body is slidably connected to the push rod.

[0119] When the slider slides along the sliding hole, the slider drives the first clamp and the second clamp to rotate relative to the outer tube through the push rod, so that the first clamp and the second clamp open or close.

[0120] When the first and second clamps are open, the clamp head is in the open state and can grasp human tissue; when the first and second clamps are closed, the clamp head is in the closed state.

[0121] By designing the biopsy forceps to include a handle, a slider, a push rod, an outer tube, and a forceps head, with the forceps head comprising a first forceps body and a second forceps body, the forceps head allows the first and second forceps bodies to rotate relative to the outer tube when the slider slides along the sliding hole. This causes the first and second forceps bodies to open or close, allowing the operator to open or close the first and second forceps bodies by sliding the slider. This enables the forceps head to grasp lesion tissue, resulting in a simple and efficient grasping action that is easy to operate and requires minimal operator skill.

[0122] A third channel is formed on the push rod, and the third channel passes through the push rod axially. One end of the third channel is connected to the first channel, and the other end of the third channel is located at the clamp head.

[0123] It enables positioning and display structures such as confocal microscope probes and ultrasound probes to pass through the first and third channels to reach the forceps head. It allows observation of human tissue through the positioning and display structure, precise positioning of lesion areas, and adjustment of the forceps head position and gripping angle based on the positioning and display results, achieving precise gripping, high gripping efficiency, and good gripping effect.

[0124] In some embodiments, a sliding hole extends through the handle. Both ends of the sliding hole are located on the side surface of the handle.

[0125] refer to Figure 2 and Figure 3 Slider 12 includes a first slider 121. Slider 12 includes a second slider 122. The first slider 121 includes a first insert block 1211. The second slider 122 includes a second insert block 1221.

[0126] The first insert is inserted into the sliding hole from one end, and the second insert is inserted into the sliding hole from the other end. The first slider and the second slider are fixedly connected.

[0127] refer to Figure 5 and Figure 6The first slider 121 includes a first slider body 1212. A first receiving groove 12121 is formed on the first slider body 1212. The first receiving groove has an open end near the first end of the handle. The first receiving groove also has an open end near the second end of the handle.

[0128] The first receiving groove 12121 has a first groove side surface 121211 located on the side of the first receiving groove. A first insert block is located on the first groove side surface. A handle is inserted into the first receiving groove.

[0129] The second slider 122 includes a second slider body 1222. A second receiving groove 12221 is formed on the second slider body 1222. The second receiving groove has an open end near the first end of the handle. The second receiving groove also has an open end near the second end of the handle.

[0130] The second receiving groove 12221 has a second groove side surface 122211 located on the side of the second receiving groove. A second insert block is located on the second groove side surface. A handle is inserted into the second receiving groove.

[0131] The slider is configured to include a first slider and a second slider. The first slider includes a first receiving groove and a first insert, and the second slider includes a second receiving groove and a second insert. This configuration enables the slider to slide on the handle and prevents the slider from detaching from the handle, resulting in a stable structure.

[0132] In some embodiments, the first insertion block 1211 and the second insertion block 1221 are disposed opposite to each other. The first insertion block has a first slot 12111 at its side end near the second insertion block. The first slot has an opening at its end near the second end of the handle. The second insertion block has a second slot 12211 at its side end near the first insertion block. The second slot has an opening at its end near the second end of the handle.

[0133] The push rod is disposed within the first slot and the second slot. The first slot and the second slot constrain the push rod onto the slider, and restrict the push rod from rotating relative to the slider.

[0134] When the handle is rotated, the handle drives the push rod to rotate synchronously with the handle via a sliding block. Specifically, when the handle is rotated, the handle drives the push rod to rotate synchronously with the handle via the first and second slots. This allows the position of the forceps head to be adjusted by rotating the handle, which changes the gripping position of the first and second forceps bodies. By finding a more suitable gripping position for the lesion area, the gripping effect and the effectiveness of the gripped tissue can be improved.

[0135] In some embodiments, reference Figure 8 The push rod 13 includes a push rod body 132. The push rod body 132 has a certain degree of flexibility and can be bent. The push rod body 132 can be a 304 stainless steel solution-treated tube, that is, the push rod body 132 can be a 304 solution-treated stainless steel tube. The push rod body 132 can also be a rod made of other materials.
