[0002] An endoscope is a testing instrument that integrates traditional optics, ergonomics, precision mechanics, modern electronics, mathematics, and software.

[0003] Endoscopic puncture processing instruments are designed to provide a stable moving channel for the use of endoscopes, ensuring the accuracy of endoscopic operations. However, existing puncture processing instruments can only perform unidirectional support operations and cannot position and clamp the endoscope connecting tube. This requires medical staff to hold the instrument continuously, which can easily cause operational fatigue. Furthermore, they cannot position the connecting tube in emergency situations, affecting the ease of use.

[0004] Therefore, we provide an endoscopic puncture treatment device. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned technical problems by providing an endoscope puncture treatment device that achieves an automatic clamping effect.

[0006] In view of this, the present invention provides an endoscopic puncture treatment device, including a support body and a support ring installed on the upper half of the outer side of the support body. The support ring is in communication with the interior of the support body. A plurality of guide grooves are formed in the middle of the inner wall of the support ring. The guide grooves extend to the interior of the side of the support ring. A clamping block is slidably disposed inside the guide groove. A guide cylinder is installed on the outer surface of the clamping block. A guide rod is slidably disposed inside the guide cylinder. The support cylinder is inserted into the side of the guide rod away from the guide cylinder. A positioning head for limiting and guiding is provided on the outer side of the guide rod. A telescopic spring is disposed inside the support cylinder. A connecting rod is installed at the end of the telescopic spring away from the guide rod. The connecting rod extends out of the outer side of the support cylinder. A rotating auxiliary rod is rotatably disposed above the connecting rod. A sliding plate is rotatably disposed at one end of the rotating auxiliary rod. A pressing ring is disposed on the outer side of the sliding plate.

[0007] Preferably, the inner wall of the guide cylinder is provided with guide rails evenly distributed, and a number of guide rails are simultaneously slidably connected to guide heads, which are installed at one end of the guide rod.

[0008] Preferably, a positioning auxiliary block is provided inside the support ring, and the positioning auxiliary block is locked to the positioning head. A support groove for sliding guidance of the positioning head is provided on the guide rod. The positioning head extends into the support groove. A return spring is installed on the lower surface of the positioning head. The return spring is installed inside the support groove. The lower half of the positioning head is larger than the junction of the positioning head and the support groove.

[0009] Preferably, the telescopic spring is provided with limit plates at both ends, and the guide rod is fixedly connected to one of the limit plates, and the connecting rod is inserted into the other limit plate and extends to the middle of the telescopic spring, and the inner end surface of the connecting rod is fixedly connected to the limit plate near the guide rod.

[0010] Preferably, the connecting rod and the rotating auxiliary rod are rotatably connected to a rotating connecting block at their adjacent ends, and the connecting rod extends outward from the outside of the support ring.

[0011] Preferably, a plurality of support frames are installed on the outer surface of the support ring, the sliding plate is slidably disposed inside the support frames, and the sliding plate is connected to the pressing ring through a surface connecting block.

[0012] Preferably, a plurality of guide frames are installed on the outer surface of the support ring, and the pressing ring is slidably disposed inside the guide frames.

[0013] Compared with the prior art, this utility model provides a puncture treatment tool for endoscopes, which has the following beneficial effects:

[0014] 1. In this utility model, when the device is in use, the pressing ring needs to be pulled first to compress the telescopic spring. At this time, the clamping block is in the extended state, and the endoscope is inserted at the same time.

[0015] 2. In this utility model, when it is necessary to urgently position and clamp the connecting tube on the endoscope, the medical staff releases the limit on the pressing ring. Under the elastic automatic reset of the telescopic spring, the clamping block can automatically and quickly clamp, thereby improving the efficiency of emergency restriction of the endoscope while ensuring the operator's attention.

[0016] 3. With the support of the guide rail itself, this utility model allows for a buffering distance between the clamping block and the guide rod when the clamping block moves, preventing the clamping block from clamping the central connecting pipe too tightly, thereby improving the safety of the device during automatic clamping.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] Example 1: An endoscopic puncture treatment device, such as Figure 1 - Figure 6As shown, the support includes a support body 1 and a support ring 2 installed on the upper part of the outer side of the support body 1. The support ring 2 is connected to the inside of the support body 1. Several guide grooves 3 are opened in the middle of the inner wall of the support ring 2. The guide grooves 3 extend to the inside of the side of the support ring 2. A clamping block 4 is slidably arranged inside the guide groove 3. A guide cylinder 5 is installed on the outer surface of the clamping block 4. A guide rod 8 is slidably arranged inside the guide cylinder 5. A support cylinder 9 is inserted into the side of the guide rod 8 away from the guide cylinder 5. A positioning head 18 for limiting and guiding is provided on the outside of the guide rod 8. A telescopic spring 10 is provided inside the support cylinder 9. A connecting rod 11 is installed on the end of the telescopic spring 10 away from the guide rod 8. The connecting rod 11 extends out of the outside of the support cylinder 9. A rotating auxiliary rod 13 is rotatably arranged above the connecting rod 11. A sliding plate 14 is rotatably arranged on one end of the rotating auxiliary rod 13. A pressing ring 16 is arranged on the outside of the sliding plate 14.

[0028] When using the device, first, press the outer pressing ring 16 to move the multiple sliding plates 14 on the periphery downwards simultaneously, causing the rotating auxiliary rod 13 to move gradually from the inclined upward direction to the horizontal direction, so that the connecting rod 11 is gradually straightened, and the telescopic spring 10 is stretched inside the support cylinder 9, causing the guide rod 8 to move into the support cylinder 9. Based on the pulling effect of the guide rod 8 on the guide cylinder 5, the guide cylinder 5 and the clamping block 4 are stretched simultaneously, causing the clamping block 4 to move outwards from the guide groove 3, expanding the distance between the multiple clamping blocks 4, so that the endoscope can move into it, and when necessary... In emergency positioning, the limiting of the pressing ring 16 is directly released. Under the rebound action of the telescopic spring 10 itself, the guide rod 8 and the connecting rod 11 move in the opposite direction inside the support cylinder 9, so that the clamping block 4 moves automatically towards the center of the device, achieving the effect of automatically clamping the connecting tube in the middle. By connecting the pressing ring 16 to multiple sliding plates 14 at the same time, the pressing ring 16 can receive the elastic force of multiple telescopic springs 10 simultaneously under the transmission of the connecting rod 11 and the rotating auxiliary rod 13, ensuring the stability and efficiency of the automatic clamping of the middle clamping block 4.

[0029] like Figure 1 - Figure 6 As shown, guide rails 6 are evenly distributed on the inner wall of the guide cylinder 5, and guide heads 7 are slidably connected inside several guide rails 6. The guide heads 7 are installed at one end of the guide rod 8.

[0030] With the mutual guidance and limiting of the guide rail 6 and the guide head 7, the guide rod 8 improves the direction and accuracy of its movement when it drives the guide cylinder 5. At the same time, with the support of the specifications of the guide rail 6 itself, the clamping block 4 and the guide rod 8 can be buffered for a distance when the clamping block 4 is moving, preventing the clamping block 4 from clamping the middle connecting pipe too tightly, thereby improving the safety of the device during automatic clamping.

[0031] like Figure 1 - Figure 6As shown, a positioning auxiliary block 20 is provided inside the support ring 2. The positioning auxiliary block 20 is locked and connected to the positioning head 18. A support groove for sliding guidance of the positioning head 18 is provided on the guide rod 8. The positioning head 18 extends into the support groove. A return spring 19 is installed on the lower surface of the positioning head 18. The return spring 19 is installed inside the support groove, and the lower half of the positioning head 18 is larger than the junction of the positioning head 18 and the support groove.

[0032] When the guide rod 8 moves automatically, the arc surface of one side of the positioning head 18 contacts the adjacent arc surface of the positioning auxiliary block 20. Based on the fixed position of the positioning auxiliary block 20 and the elastic action of the return spring 19, the positioning head 18 is pressed and moves down automatically. Then, under the guide limit of the support groove, the movement distance of the positioning head 18 is limited. After the positioning head 18 moves out of the range of the positioning auxiliary block 20, it automatically rebounds under the elasticity of the return spring 19. When the guide rod 8 moves in the opposite direction again, it is limited by the resistance of the inclined surface of the positioning head 18 and the inclined surface of the positioning auxiliary block 20, which forms a limiting effect on the positioning head 18 and the positioning auxiliary block 20, fixing the position of the guide rod 8. Only when it is forcibly pulled by an external force will the positioning head 18 retract and spring up again.

[0033] Example 2: An endoscopic puncture treatment device, such as Figure 1 - Figure 6 As shown, the telescopic spring 10 has limit plates at both ends, and the guide rod 8 is fixedly connected to one of the limit plates. The connecting rod 11 is inserted into the other limit plate and extends to the middle of the telescopic spring 10. The inner end surface of the connecting rod 11 is fixedly connected to the limit plate on the side near the guide rod 8.

[0034] First, the limiting plate on the side closer to the guide rod 8 is set to slide inside the support cylinder 9, and the limiting plate on the side farther from the guide rod 8 is set to be fixed inside the support cylinder 9. When the connecting rod 11 is pulled, it will slide inside the fixed limiting plate, causing the telescopic spring 10, the sliding limiting plate, and the guide rod 8 to slide inside the support cylinder 9, causing the telescopic spring 10 to contract and compress. When the tension on the connecting rod 11 is released, under the elastic action of the telescopic spring 10 itself, the connecting rod 11 and the guide rod 8 will move in the opposite direction, thereby achieving the effect of automatic movement and limiting of the middle fastening component.

[0035] like Figure 1 - Figure 6 As shown, the connecting rod 11 and the rotating auxiliary rod 13 are rotatably connected to a rotating connecting block 12 at their adjacent ends, and the connecting rod 11 extends out of the outer side of the support ring 2.

[0036] Several support frames 15 are installed on the outer surface of the support ring 2. The sliding plate 14 is slidably disposed inside the support frame 15. The sliding plate 14 is connected to the pressing ring 16 through the surface connecting block.

[0037] Several guide frames 17 are installed on the outer surface of the support ring 2, and the pressing ring 16 is slidably disposed inside the guide frame 17.

[0038] Under the guidance and support of the guide frame 17, the moving direction and distance of the pressing ring 16 are limited. With multiple connecting blocks connecting the sliding plate 14 and the pressing ring 16 at the same time, it is ensured that when the pressing ring 16 moves, it can drive multiple sliding plates 14 to slide simultaneously inside the corresponding support frame 15, and simultaneously expand and pull multiple rotating auxiliary rods 13 on the outside, thereby improving the effect of simultaneous movement of the lower rotating connecting block 12.

[0039] Working principle: When the device is not in use, the central clamping block 4 is clamped due to the extension of the telescopic spring 10. When the device is in use, the pressing ring 16 needs to be pulled first to compress the telescopic spring 10. At this time, the clamping block 4 is in an expanded state, and the endoscope is inserted. When it is necessary to urgently position and clamp the connecting tube on the endoscope, the medical staff releases the limit on the pressing ring 16. Under the elastic automatic reset of the telescopic spring 10, the clamping block 4 can automatically and quickly clamp, thereby improving the efficiency of emergency restraint of the endoscope while ensuring the operator's attention.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
