Technical Field

[0001] The utility model belongs to the field of medical technology, and specifically relates to a disposable stable gastrointestinal living tissue sampling forceps. Background Technique

[0002] Gastrointestinal living tissue sampling forceps are mainly used to take small pieces of tissue from suspected lesion sites for pathological analysis. This tool can accurately locate the target position and gently grab a small tissue sample, which helps to diagnose inflammation, ulcers or other abnormalities in the digestive tract.

[0003] The disposable living tissue sampling forceps enter the human body through the monitoring function of the endoscopic forceps. Align the forceps head with the lesion site, then open the forceps mouth and push the handle slider to close the sampled tissue. Then close the forceps mouth and pull the handle slider to pull the outer tube backward, and finally take out the sampling forceps.

[0004] Currently, in the prior art, when the sampling forceps take samples from the lesion site, due to the relatively smooth surface of the pull ring and the fact that doctors usually wear gloves, it may lead to the problem of slipping during the process of doctors pulling the pull ring, increasing the difficulty of the operation. Therefore, a disposable stable gastrointestinal living tissue sampling forceps is proposed to solve the above problems. Content of the Utility Model

[0005] In order to make up for the deficiencies of the prior art and solve at least one technical problem proposed in the background technique, the utility model proposes a disposable stable gastrointestinal living tissue sampling forceps.

When the pull ring 22 is pulled upward, it drives the pull rod 23 to slide upward, causing the pull rod 23 to pull the guide block 25 to slide upward. When the guide block 25 moves upward, it drives the clamping sampling forceps rod 26 to rotate, so that the other end of the clamping sampling forceps rod 26 rotates through the hinge shaft 28 for clamping, to quickly clamp and sample the in-vivo tissue.

[0025] Further, as shown in Figure 3 , the guiding unit includes a guiding plate 24; the inner side wall of the living body sampling forceps housing 1 is fixedly connected with the guiding plate 24, and the guiding block 25 is slidably connected to the inner side wall of the guiding plate 24; the top of the guiding block 25 is fixedly connected with a spring 29, and the other end of the spring 29 is fixedly connected to the inner side wall of the guiding plate 24; during operation, when the guiding block 25 slides upward, it is guided by the guiding plate 24 to improve the clamping stability of the clamping sampling forceps rod 26, and then the spring 29 is compressed to generate elastic force during sliding, which is convenient for releasing the living body by loosening the pull ring 22 at the end of the living body sampling, so that the spring 29 pushes the guiding block 25 to slide downward for resetting.

[0026] Further, as shown in Figure 4 , an air cushion 55 is fixedly connected to the surface of the protective pad 51; an airbag 53 is fixedly connected to the inner side wall of the pull ring 22; the end of the airbag 53 is fixedly connected with an air pipe 54, and the other end of the air pipe 54 is fixedly connected to the end of the air cushion 55; during operation, when the protective pad 51 is squeezed and moves towards the end, the air inside is squeezed through the airbag 53 and flows into the air cushion 55 through the air pipe 54, and then the air cushion 55 expands and fits on the surface of the finger for protection, so as to reduce the problem of finger strain during the pulling process.

[0027] Further, as shown in Figures 1-2 , a diversion pipe 33 is fixedly connected to the bottom of the medicine adding pipe 31; a medicine spraying head 34 is fixedly connected to the end of the diversion pipe 33; a sealing plate 32 is slidably connected to the inner side wall of the medicine adding pipe 31 and is located at the end of the pull rod 23; during operation, when the pull ring 22 drives the pull rod 23 to slide upward, after the clamping sampling forceps rod 26 clamps the living body, the sealing plate 32 is driven to slide upward to open the diversion pipe 33, so that the liquid medicine inside the medicine adding pipe 31 flows through the diversion pipe 33 into the medicine spraying head 34, and then is sprayed onto the wound through the medicine spraying head 34 for medicine application.

[0028] Further, as shown in Figures 1-2 , a lighting device 4 is fixedly connected to the end of the living body sampling forceps housing 1; during operation, by installing the lighting device 4 at the end of the living body sampling forceps housing 1, it can provide illumination, which is convenient for medical staff to clamp the living body.

[0029] Further, as shown in Figure 4 , a friction pad is fixedly connected to the surface of the air cushion 55; the end of the protective pad 51 is semi-circular and symmetrically arranged; during operation, by installing the friction pad at the end of the air cushion 55, the friction between the air cushion 55 and the finger is increased, and the problem of subsequent slippage is reduced.

[0030] Working principle: When medical staff take samples through the outer shell 1 of the in-vivo sampling forceps, they insert their fingers into the inside of the pull ring 22. During the insertion process, the surface of the protective pad 51 is squeezed, causing the protective pad 51 to slide to both sides and squeeze the elastic piece 52 to generate elastic force, so that the protective pad 51 closely fits on the surface of the finger for clamping and fixing, and plays a protective effect. When the pull ring 22 is pulled upward, it drives the pull rod 23 to slide upward, causing the pull rod 23 to pull the guide block 25 to slide upward. When the guide block 25 moves upward, it drives the clamping sampling forceps rod 26 to rotate, so that the other end of the clamping sampling forceps rod 26 rotates through the hinge shaft 28 for clamping, to quickly clamp and sample the in-vivo; when the guide block 25 slides upward, it is guided by the guide plate 24 to improve the clamping stability of the clamping sampling forceps rod 26, and then squeezes the spring 29 to generate elastic force when sliding. After the in-vivo sampling is completed, by releasing the pull ring 22, the spring 29 pushes the guide block 25 to slide downward for resetting to release the in-vivo; when the protective pad 51 is squeezed and moves toward the end, the gas inside is squeezed through the airbag 53 and flows through the trachea 54 into the inside of the air cushion 55, and then the air cushion 55 expands and fits on the surface of the finger for protection, to reduce the problem of scratching of the finger during the pulling process; when the pull ring 22 drives the pull rod 23 to slide upward, after the clamping sampling forceps rod 26 clamps the in-vivo, it drives the sealing plate 32 to slide upward to open the diversion tube 33, so that the liquid medicine in the medicine adding tube 31 flows through the diversion tube 33 into the inside of the spraying head 34, and then is sprayed onto the wound through the spraying head 34 for medicine application; by installing a lighting device 4 at the end of the in-vivo sampling forceps outer shell 1, it plays an illuminating effect, facilitating the medical staff to clamp the in-vivo; by installing a friction pad at the end of the air cushion 55, it improves the friction between the air cushion 55 and the finger, reducing the subsequent problem of slipping.
