Abstract

The present invention discloses a lateral sampling biopsy device for an endoscope, belonging to the technical field of medical devices. The key points of its technical solution include a forceps head seat. A mounting column is fixedly connected to the rear of the upper end surface of the forceps head seat. A connecting column is fixedly connected to the upper end surface of the mounting column. The bottoms of the left forceps head and the right forceps head are connected to a cable through a cable buckle. Thus, by pulling the left and right cables, the left forceps head and the right forceps head can be opened and closed, capable of clamping tissues near the forceps head. At the same time, in a narrow lumen, such as the bile duct, through the blind sampling method, effective tissues can be effectively clamped for pathological diagnosis. The left forceps head and the right forceps head open and close from the side, thus facilitating the clamping of lateral tissues and making it more convenient to use, solving the problem that all the endoscope sampling devices currently used clinically are designed for front-end sampling and are unable to sample lateral tissues, making them very inconvenient to use.

Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to a lateral sampling biopsy device for an endoscope. Background Art

[0002] An endoscope is a detection instrument integrating traditional optics, ergonomics, precision machinery, modern electronics, mathematics, software, etc. It has an image sensor, an optical lens, a light source for illumination, a mechanical device, etc., and it can enter the stomach through the oral cavity or enter the body through other natural orifices. With the endoscope, lesions that cannot be shown by X-rays can be seen, so it is very useful for doctors. For example, with the help of an endoscope, a doctor can observe ulcers or tumors in the stomach and thus formulate the best treatment plan.

[0003] Providing pathological tissues for further examination is an important function of endoscope technology. Currently, all the endoscope sampling devices used clinically are designed for front-end sampling and cannot sample lateral tissues, which is very inconvenient to use. Summary of the Invention

[0004] In view of the above problems, the present invention proposes a lateral sampling biopsy device for an endoscope to solve the above problems.

[0005] The present invention is implemented as follows. A lateral sampling biopsy device for an endoscope includes:

[0006] A clamp head seat, an installation column is fixedly connected to the rear of the upper end surface of the clamp head seat, and a connection column is fixedly connected to the upper end surface of the installation column;

[0007] A left clamp head and a right clamp head, both the left clamp head and the right clamp head are movably connected to the outer wall of the connection column through hinge seats.

[0008] To facilitate the insertion and installation of a cable, as a preferred embodiment of the lateral sampling biopsy device for an endoscope of the present invention, a spring tube is fixedly connected to the lower end surface of the clamp head seat, a cable passage is penetrated and opened in front of the upper end surface of the clamp head seat, and the cable passage is communicated with the inside of the spring tube.

[0009] To facilitate controlling the opening and closing of the left clamp head and the right clamp head through a cable, as a preferred embodiment of the lateral sampling biopsy device for an endoscope of the present invention, two cables are movably connected to the inside of the cable passage, the bottoms of both the two cables extend into the inside of the spring tube, cable buckles are fixedly connected to the bottoms of both the left clamp head and the right clamp head, and the upper ends of the two cables are respectively inserted into the inside of the two cable buckles.

[0010] To facilitate clamping tissues from the side, as a preferred embodiment of the lateral sampling biopsy device for an endoscope of the present invention, the left clamp head and the right clamp head have the same structure and are both in an elliptical hemispherical shape.

[0011] In order to facilitate the opening and closing of the clamping head by rotating the cable, as an optimal choice of the lateral sampling biopsy device for endoscopes in the present invention, the upper half of the cable has a smoothly transitioned bent structure.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] The bottoms of the left clamping head and the right clamping head are connected to the cable through cable buckles. Thus, by pulling the left and right cables, the left clamping head and the right clamping head can be opened and closed, capable of clamping the tissues near the clamping head. At the same time, in a narrow lumen, such as in the bile duct, through the blind sampling method, effective tissues can be effectively clamped for pathological diagnosis. The left clamping head and the right clamping head open and close from the side, thus facilitating the clamping of the lateral tissues and being more convenient to use. Description of the Drawings

[0022] A left jaw head 4 and a right jaw head 5, both the left jaw head 4 and the right jaw head 5 are movably connected to the outer wall of the connecting post 3 through hinge seats 6.

[0023] In this embodiment: The jaw head base 1 facilitates the connection of the mounting post 2 and the spring tube 7 at the bottom. A connecting post 3 is fixedly connected to the upper end surface of the mounting post 2. Both the left jaw head 4 and the right jaw head 5 are movably connected to the outer wall of the connecting post 3 through hinge seats 6, so that the left jaw head 4 and the right jaw head 5 can be flexibly opened and closed in the lateral direction.

[0024] As a technical optimization scheme of the present invention, a spring tube 7 is fixedly connected to the lower end surface of the jaw head base 1, and a cable hole 8 is penetrated and opened in front of the upper end surface of the jaw head base 1, and the cable hole 8 communicates with the inside of the spring tube 7.

[0025] In this embodiment: The cable hole 8 communicates with the inside of the spring tube 7, which facilitates the two cables 9 to pass through the cable hole 8 and enter the inside of the spring tube 7, and facilitates controlling the opening and closing of the jaw heads by the cables 9 from the bottom.

[0026] As a technical optimization scheme of the present invention, two cables 9 are movably connected to the inside of the cable hole 8, the bottoms of the two cables 9 both extend to the inside of the spring tube 7, and cable buckles 10 are fixedly connected to the bottoms of the left jaw head 4 and the right jaw head 5, and the upper ends of the two cables 9 are respectively inserted into the inside of the two cable buckles 10.

[0027] In this embodiment: The left jaw head 4 and the right jaw head 5 are connected to the cables 9 through the cable buckles 10 at the bottom, so that the left jaw head 4 and the right jaw head 5 can be opened and closed by pulling the left and right cables 9, and can clamp the tissue near the jaw heads. At the same time, in a narrow lumen, such as in the bile duct, through the blind extraction method, effective tissue can be effectively clamped for pathological diagnosis. The left jaw head 4 and the right jaw head 5 open and close from the side, so as to facilitate clamping the lateral tissue and is more convenient to use.

[0030] As a technical optimization scheme of the present invention, the upper half of the cable 9 is a bent structure with a smooth transition.

[0031] In this embodiment: The upper half of the cable 9 is a bent structure with a smooth transition, so that when the cable 9 is rotated, the opening and closing of the left jaw head 4 and the right jaw head 5 can be controlled, and the control is convenient.

[0032] Working principle and usage process of the present invention: The bottoms of the left jaw 4 and the right jaw 5 are connected to the cable 9 through the cable buckle 10. Thus, by pulling the left and right cables 9, the left jaw 4 and the right jaw 5 can be opened and closed, capable of clamping the tissue near the jaws. At the same time, in a narrow lumen, such as the bile duct, through the blind extraction method, effective tissue can be effectively clamped for pathological diagnosis. The left jaw 4 and the right jaw 5 open and close from the side, thus facilitating the clamping of the lateral tissue and making the use more convenient.
