Description

Technical Field

[0001] The utility model relates to the field of digestive endoscopes, in particular to a digestive endoscope biopsy forceps with a spraying function. Background Art

[0002] Digestive endoscopes are a group of devices that directly obtain images through the digestive tract or obtain ultrasound or X-ray images of the digestive tract and digestive organs through devices equipped with ultrasound and X-rays to diagnose and treat digestive system diseases. According to the attributes of the endoscopes used for examination, they can be divided into esophagoscopes, gastroscopes, duodenoscopes, colonoscopes, enteroscopes, endoscopic ultrasounds, capsule endoscopes, choledochoscopes (including mother-daughter endoscopes), pancreatic duct endoscopes, laparoscopes, and laser confocal endoscopes, etc.

[0003] For example, a digestive endoscope biopsy forceps with a spraying function with the publication number of CN220385109U proposed in the prior art. When spraying a dye on a lesion, it opens the clamping edge. During the opening process of the clamping edge, the spraying tube can be pushed forward to approach the lesion, and then it is stained. There is no need to spray separately through a spraying tube, which is more time-saving and labor-saving. When the clamping edge clamps the lesion, the spraying tube will be driven to contract backward during the closing process of the clamping edge, preventing the spraying tube from blocking in the front and hindering the clamping, and it is more flexible and convenient to use.

[0004] However, when sampling through the biopsy forceps, one end of the spraying tube will contact the lesion, causing the lesion to enter the inside of the spraying tube, which easily leads to the residue of the lesion inside the spraying tube, resulting in inconvenience for later cleaning and affecting subsequent use.

[0005] Therefore, it is necessary to provide a digestive endoscope biopsy forceps with a spraying function to solve the above technical problems. Summary of the Utility Model

[0006] The utility model provides a digestive endoscope biopsy forceps with a spraying function, which solves the problem that the lesion enters the inside of the spraying tube and easily remains inside the spraying tube.

Specific embodiments

[0026] The present utility model will be further described below with reference to the accompanying drawings and embodiments.

[0027] First embodiment

[0028] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , wherein Figure 1 Schematic structural diagram of the first embodiment of a digestive endoscope biopsy forceps with a spraying function provided by the present utility model; Figure 2 is Figure 1 Schematic structural diagram of the rotating frame shown in the figure; Figure 3 is Figure 1 Enlarged schematic diagram of part A shown in the figure; Figure 4 is Figure 2 Enlarged schematic diagram of part B shown in the figure. A digestive endoscope biopsy forceps with a spraying function includes:

[0029] Linkage tube 1, one end of the linkage tube 1 is provided with an operating handle 2, and one side of the linkage tube 1 is provided with a delivery tube 3;

[0030] Forceps head 4, the forceps head 4 is arranged at one end of the linkage tube 1, two moving grooves 41 are formed inside the forceps head 4, two moving blocks 42 are slidably connected inside the two moving grooves 41, one ends of the two moving blocks 42 are both provided with return springs 43, and one ends of the two moving blocks 42 are fixedly connected with moving rods 44;

[0031] Rotating frame 5, the rotating frame 5 is arranged inside the moving block 42, a nozzle 51 is arranged inside the rotating frame 5, one end of the nozzle 51 is fixedly connected with a telescopic tube 52, a telescopic sleeve 53 is sleeved on the surface of the telescopic tube 52, and a limiting ring 54 is fixedly connected inside the telescopic sleeve 53.

[0032] The two reset springs 43 are respectively arranged at one end of the two moving blocks 42 and are respectively arranged inside the two moving grooves 41.

[0033] The telescopic sleeve 53 is fixedly installed inside the linkage pipe 1, and the telescopic pipe 52 is slidably connected inside the telescopic sleeve 53.

[0034] Both ends of the rotating frame 5 are respectively rotatably connected inside the two moving blocks 42, and a limiting ring 54 is also fixedly connected inside the rotating frame 5.

[0035] One end of the moving rod 44 is fixedly connected to one end of the moving block 42, and is used to push the two moving blocks 42 to move to one side after the clamping head 4 moves to one side and contacts an object.

[0036] The rotating frame 5 is composed of two rotating rods and a rotating plate. One ends of the two rotating rods are both rotatably connected inside the rotating plate, and the other ends are respectively rotatably connected inside the two moving blocks 42. The nozzle 51 is fixedly installed inside the rotating plate.

[0037] Limiting rings 54 are fixedly connected inside both the rotating plate and the telescopic sleeve 53. The limiting rings 54 are magnets, and after the two limiting rings 54 adsorb each other, the rotating plate is limited.

[0038] The working principle of a digestive endoscope biopsy forceps with a spraying function provided by the present utility model is as follows:

[0039] During use, when the clamping head 4 rotates and opens to one side, it drives the rotating frame 5 to rotate and open to one side, causing the nozzle 51 to move to one side and driving the telescopic pipe 52 to move to one side inside the telescopic sleeve 53. After the limiting ring 54 inside the rotating frame 5 is separated from the limiting ring inside the telescopic sleeve 53, the two reset springs 43 push the two moving blocks 42 to move to one side respectively inside the two moving grooves 41 to a suitable position.

[0040] When sampling is required, when the clamping head 4 moves to one side, it pushes the moving rod 44 to move to one side, thereby driving the two moving blocks 42 to move to one side respectively inside the two moving grooves 41. At the same time, the two reset springs 43 are compressed, so that the rotating frame 5 rotates to one side and moves to one side, causing the nozzle 51 to move away from the surface of the diseased body.

[0041] When the clamping head 4 rotates and closes to one side, the rotating frame 5 rotates to one side. Thus, after the clamping head 4 is closed, the limiting ring 54 inside the rotating frame 5 and the limiting ring 54 inside the telescopic pipe 52 adsorb each other, and the rotating frame 5 is limited.

[0042] Compared with the related art, a digestive endoscope biopsy forceps with a spraying function provided by the present utility model has the following beneficial effects:

[0043] The present utility model provides a digestive endoscope biopsy forceps with a spraying function. When the biopsy forceps need to take a sample, when the forceps head 4 moves to one side, two moving rods 44 will move to one side, causing the rotating frame 5 to move to one side, so that the nozzle 51 moves away from the surface of the diseased body, thereby preventing the diseased body from entering the inside of the nozzle 51 and preventing the diseased body from remaining in the inside of the nozzle 51, which is convenient for subsequent cleaning and the like.
