Description

Visible endoscope biopsy forceps

technical field

The utility model belongs to the technical field of medical products, in particular to a visible endoscope biopsy forceps.

Background technique

Endoscopic examination, treatment or surgery is one of the most commonly used clinical methods, and various biopsy materials through endoscopes are indispensable methods for diagnosing related diseases.

However, when the internal diameter of the organ is too small, or when there is a stenosis in the middle, ordinary conventional endoscopes cannot enter, let alone obtain diseased tissue.

If there is a thinner endoscope so that inspectors can see the lesions in the inside or further away, and can clamp the lesions under direct vision, it is very important to solve the clinical diagnosis or treatment.

If the above technology can be realized, it will undoubtedly improve the efficiency of diagnosis and treatment for patients with small incisions or small inner diameters, or lesions located in the distal end, or in the peripheral parts of the organs. Therefore, the research and development of this product has important clinical significance and social significance. value.

In order to achieve the above purpose, the technical solution adopted in the utility model is: comprising a biopsy forceps insertion part, the front end of the biopsy forceps insertion part is provided with a clamp and an objective lens, and the rear end of the biopsy forceps insertion part is provided with a biopsy forceps capable of manipulating the clamps In the operation part, the objective lens is connected to an external monitor, and the clamp and the objective lens can be inserted through the insertion part of the biopsy forceps into a lesion with a small incision, a narrow inner diameter, located at the far end or at the periphery of the organ.

The insertion part of the biopsy forceps is a hollow structure, and an optical fiber is arranged in the hollow structure, and the objective lens is connected to an external display through the optical fiber.

The outer diameter of the insertion part of the biopsy forceps is less than 2mm.

The rear end of the insertion part of the biopsy forceps is provided with a video transmission interface, and the optical fiber is connected to an external display through the video transmission interface.

The operating part of the biopsy forceps includes a clamping part and a finger ring.

The video transmission interface is located at the front of the clamping part and the ring.

Compared with the prior art, the utility model sets the insertion part of the biopsy forceps, and uses the insertion part of the biopsy forceps to extend into the incision with a small, narrow inner diameter, and is located at the far end or at the peripheral part of the organ, and the front end of the insertion part of the biopsy forceps is set Send the biopsy forceps into the lesion with the objective lens, use the operating part of the biopsy forceps to control the clamp, use the objective lens to connect to an external monitor, and can clearly observe the lesion position, which is convenient for the clamp to grasp the lesion tissue for diagnosis and treatment. The utility model aims at the problem that when the inner diameter of the organ is too small, or when there is narrowness in the middle, ordinary conventional endoscopes cannot enter, and the diseased tissue cannot be obtained. , or when it is located at the peripheral parts of the organs, the utility model can be used to complete the above inspection and treatment work, which is very beneficial to improving the efficiency of diagnosis and treatment and improving the level of medical technology. The research and development of the utility model has important social value and considerable economic benefits. benefit.

Further, the insertion part of the biopsy forceps is a hollow structure, and an optical fiber is arranged in the hollow structure, and the objective lens is connected to an external display through the optical fiber, so that the optical fiber is hidden inside the insertion part of the biopsy forceps, which improves the integrity of the entire device, is easy to operate, and transmits The image is beneficial for the operator to diagnose and treat the patient.

Furthermore, the outer diameter of the insertion part of the biopsy forceps is less than 2 mm, which belongs to the ultra-thin form, which is the thinnest at present, and can better adapt to small incisions, narrow and small inner diameters, or lesions located in the distal end, or located in the peripheral parts of the organs. The situation, to ensure the smooth progress of diagnosis and treatment.

Furthermore, the external monitor is connected through the video transmission interface to ensure that the images collected by the objective lens can be accurately displayed on the external monitor, providing accurate basis for operating biopsy forceps and diagnosis.

Furthermore, the video transmission interface is located at the front end of the clamping part and the finger ring, which does not affect the operator's operation of the biopsy forceps and improves the practicability of the whole device.

The insertion part of the biopsy forceps can be directly inserted into the stenosis of the inner lumen of the organ, or it can be inserted through the biopsy hole of the conventional endoscope, and the biopsy hole of the conventional endoscope is used as the reference point, which makes the operation of the utility model more accurate and improves the overall device reliability.

Detailed ways

Below in conjunction with embodiment the utility model is further described.

Referring to Fig. 1, the utility model comprises biopsy forceps insertion part 1, and the outer diameter of biopsy forceps insertion part 1 is less than 2mm, and biopsy forceps insertion part 1 is hollow structure, is provided with optical fiber 4 in the hollow structure, and the front end of biopsy forceps insertion part 1 A clamp 2 and an objective lens 3 are provided, and the rear end of the biopsy forceps insertion part 1 is provided with a biopsy forceps operating part 5 capable of manipulating the clamps 2 and a video transmission interface 6. The biopsy forceps operating part 5 includes a clamping part and a ring, and video transmission The interface 6 is located at the front end of the clamping part and the ring, the objective lens 3 is connected to an external display through an optical fiber 4, and the optical fiber 4 is connected to an external display through a video transmission interface 6. The clamp 2 and the objective lens 3 can extend into the incision through the biopsy forceps insertion part 1 Lesions that are small, narrow in diameter, located distally, or located at the periphery of the organ. The biopsy forceps insertion part 1 extends from the narrow part 8 of the internal lumen of the organ when working, or extends from the narrow part of the internal lumen 8 of the organ through the biopsy hole of a conventional endoscope.
