[0002] Clinical grippers for digestive endoscopy are key tools used in digestive endoscopy procedures, primarily for grasping, securing, or removing tissues, lesions, or foreign bodies within the digestive tract.

[0003] In clinical practice, endoscopic examinations often require medical staff to hold the endoscope by hand, especially in the application of digestive endoscopy. Because medical staff hold the endoscope for a long time, they are prone to fatigue, which affects the field of vision of the endoscope. The existing digestive endoscope holder has a simple structure. Once the endoscope is fixed, it is not easy to change its position. It is impossible to adjust the position and angle of the endoscope in actual use, which is not flexible enough and has poor practicality.

[0004] Therefore, we propose a clinical gripper for digestive endoscopy that is easy to adjust in angle to solve the problems mentioned above. Summary of the Invention

[0026] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1: Please refer to Figure 1 - Figure 7As shown, a clinical gripper for digestive endoscopy with adjustable angle includes a base 1. A support column 4 is movably connected to the upper end of the base 1 via a connecting rod 3. A horizontal adjustment mechanism 2 is installed inside the base 1. The horizontal adjustment mechanism 2 includes a movable rod 201, which is movably installed inside the support column 4. A trapezoidal block 202 is hinged to the lower end of the movable rod 201. A locking block 203 is provided at each of the four corners of the upper surface of the trapezoidal block 202. Wedge blocks 204 abut against the left and right sides of the lower end of the trapezoidal block 202. A compression spring 208 is provided on the side of each wedge block 204 away from the trapezoidal block 202. A [missing information - likely a device or mechanism] is provided at the front end of each wedge block 204. L-shaped limiting toothed plates 205, with gears 206 meshing between the two L-shaped limiting toothed plates 205. The gears 206 are located on the circumferential surface of the front end of the connecting rod 3. When the two L-shaped limiting toothed plates 205 mesh with the left and right sides of the gears 206 respectively, the gears 206 can be locked, preventing the gears 206 from rotating. Consequently, the connecting rod 3 cannot rotate, thus limiting and fixing the support column 4 and preventing the support column 4 from rotating during use and affecting the performance. A horizontal moving plate 207 is slidably installed inside the base 1. The lower end of the trapezoidal block 202, the wedge block 204, and the rear end of the L-shaped limiting toothed plates 205 are all located inside the horizontal moving plate 207.

[0028] The base 1 has, from top to bottom, a movable through slot 12, a second horizontal movable slot 11, and a first horizontal movable slot 10. A horizontal movable plate 207 is located inside the first horizontal movable slot 10, and the upper end of the trapezoidal block 202 is located inside the second horizontal movable slot 11. The hinge pin connecting the movable rod 201 and the trapezoidal block 202 is located inside the movable through slot 12. The arrangement of the movable through slot 12, the second horizontal movable slot 11, and the first horizontal movable slot 10 allows the horizontal movable plate 207 to move horizontally left and right within the first horizontal movable slot 10, the trapezoidal block 202 to move horizontally left and right within the second horizontal movable slot 11, and the hinge pin to move horizontally left and right within the movable through slot 12, thereby allowing the support column 4 to move horizontally. The horizontal movement allows for adjustment of the horizontal position of the support column 4, improving its practicality. The upper ends of the front and rear sides of the horizontal movement groove 11 are provided with slots 13, and several slots 13 are arranged in a horizontal array. All slots 13 are located inside the base 1. Four locking blocks 203 are respectively inserted into the four left-side slots 13. The slots 13 allow the wedge block 204 to reset via the spring force of the compression spring 208 after the support column 4 has moved, thus pushing the trapezoidal block 202 back to its initial position. This allows the locking blocks 203 on the upper surface of the trapezoidal block 202 to be inserted into the corresponding slots 13, limiting and fixing the trapezoidal block 202 and the horizontal movement plate 207, thereby limiting and fixing the horizontal direction of the support column 4.

[0029] An annular mounting block 209 is provided on the circumferential surface of the upper end of the movable rod 201, and a lifting spring 210 is provided on the lower surface of the annular mounting block 209. Both the annular mounting block 209 and the lifting spring 210 are movably mounted inside the support column 4. The lifting spring 210 is designed so that when the movable rod 201 is pressed down to adjust the support column 4, and the movable rod 201 is released, the lifting spring 210 can push the annular mounting block 209 and the movable rod 201 upward to reset them, so that the upper surface of the trapezoidal block 202... The locking block 203 has a better locking effect, which further improves the limiting effect of the horizontal moving plate 207. The support column 4 has a lifting groove 14 in the middle, and a pressing protrusion 211 is slidably installed inside the lifting groove 14. The rear end of the pressing protrusion 211 is fixedly connected to the front of the upper end of the movable rod 201. The setting of the lifting groove 14 provides the pressing protrusion 211 with a space for movement, so that the pressing protrusion 211 can move vertically inside the lifting groove 14, which makes it easier for medical staff to press the movable rod 201 downward through the pressing protrusion 211.

[0030] Example 2: Please refer to the following: Figure 1 , Figure 5 - Figure 7 As shown, a horizontal plate 5 is rotatably connected to the right side of the upper end of the support column 4 via a rotating support rod 18. A rotating plate 6 is rotatably connected to the inside of the right end of the horizontal plate 5 via a rotating support rod 18. A limit mechanism 7 is provided at the front end of each of the two rotating support rods 18. The limit mechanism 7 includes a fixed sleeve block 701. The two fixed sleeve blocks 701 are fixedly connected to the front of the support column 4 and the front of the horizontal plate 5, respectively. A pull rod 702 is movably installed inside the front end of the fixed sleeve block 701. A connecting block 703 is provided at the rear end of the pull rod 702. A compression spring 704 is sleeved on the circumferential surface of the connecting block 703. A cross-shaped insert block 705 is provided at the rear end of the connecting block 703.

[0031] The rotating support rod 18 has a cross-shaped slot at its front end that matches the cross-shaped insert 705. When medical staff need to rotate the horizontal plate 5 or the rotating plate 6, they need to first move the cross-shaped insert 705 out of the cross-shaped slot using the pull rod 702. At this time, the rotating support rod 18 loses its limiting and fixing effect, and then the horizontal plate 5 can be rotated vertically. When in use, the horizontal plate 5 can be rotated to a horizontal position. When not in use, the horizontal plate 5 can be rotated to a vertical position and fitted with the support column 4 for storage, reducing the space occupied. Similarly, when in use, the rotating plate 6 can be rotated out of the horizontal plate 5 and rotated to a vertical position for use. When not in use, the rotating plate 6 can be screwed into the horizontal plate 5 and folded for storage, reducing the space occupied by the equipment.

[0032] The rotating plate 6 is internally equipped with a lifting mechanism 8, which includes a rotating rod 801. The rotating rod 801 is rotatably mounted inside the upper end of the rotating plate 6. A conical transmission wheel 802 is provided at the right end of the rotating rod 801. A conical driven wheel 803 is meshed with the lower end of the conical transmission wheel 802. A threaded rod 804 is provided at the lower end of the conical driven wheel 803. A lifting sleeve 805 is threadedly connected to the circumferential surface of the lower end of the threaded rod 804.

[0033] The rotating plate 6 has a lifting limit groove 16 inside, and there are two lifting limit grooves 16 symmetrically arranged on the left and right sides. The lower end of each of the two lifting limit grooves 16 is slidably installed with a limit block 806. The two limit blocks 806 are respectively set on the left and right sides of the upper end of the lifting sleeve plate 805. The setting of the lifting limit groove 16 provides the limit block 806 with a space for movement, so that the limit block 806 can move vertically smoothly inside the lifting limit groove 16. The setting of the limit block 806 can limit the lifting sleeve plate 805, so that when the threaded rod 804 rotates, the lifting sleeve plate 805 can move vertically upward smoothly, thereby driving the clamped equipment to move vertically upward, avoiding the equipment being too low and affecting the operation of medical staff.

[0034] Example 3: Please refer to the following: Figure 6 , Figure 7As shown, a clamping and rotating mechanism 9 is provided at the lower end of the lifting sleeve 805. The clamping and rotating mechanism 9 includes a mounting base 901. A movable sleeve block 902 and a lifting spring 903 are provided on the upper surface of the mounting base 901. A gear tooth 905 is provided on the inner circumferential wall of the upper end of the movable sleeve block 902, and a gear tooth 904 is provided on the circumferential surface of the lower end of the lifting sleeve 805. The gear tooth 904 meshes with the gear tooth 905. When the gear tooth 904 and the gear tooth 905 are meshed, they can lock each other, preventing the mounting base 901 and the movable sleeve block 902 from rotating laterally. When the mounting base 901 drives the movable sleeve block 902 to move vertically upward, the gear tooth 904 and the gear tooth 905 are no longer meshed. At this time, the mounting base 901 and the movable sleeve block 902 can be rotated laterally. The device can rotate laterally, thereby adjusting the lateral angle of the clamping device. The inner top wall of the movable sleeve block 902 abuts against the gear tooth 904, and the upper end of the lifting spring 903 abuts against the gear tooth 904. The mounting base 901 is rotatably mounted with threaded rod 2 906 and threaded rod 3 907, and the rear end of threaded rod 2 906 is fixedly connected to the front end of threaded rod 3 907. The circumferential surfaces of threaded rod 2 906 and threaded rod 3 907 are threadedly connected with moving blocks 908. The right ends of the two moving blocks 908 are provided with clamping plates 909. The threads on the surfaces of threaded rod 2 906 and threaded rod 3 907 are in opposite directions, so that when threaded rod 2 906 and threaded rod 3 907 rotate, the two moving blocks 908 and the two clamping plates 909 can move closer to each other to clamp and fix the device or move away from each other to lose the clamping and fixing effect on the device.

[0035] The bottom of the horizontal plate 5 is provided with a storage groove 15, and the length of the storage groove 15 matches the overall length of the lifting mechanism 8 and the clamping rotation mechanism 9. The upper right side of the support column 4 is provided with a placement groove 17, and the placement groove 17 matches the two clamping plates 909. The storage groove 15 and the placement groove 17 are designed so that when the rotating plate 6 is not in use, the rotating plate 6 can be screwed into the storage groove 15. Then the horizontal plate 5 is rotated and folded so that the horizontal plate 5 and the support column 4 are in contact and parallel. At this time, the clamping plate 909 is located inside the placement groove 17, realizing the storage and protection effect of the clamping plate 909.

[0036] In use, the observation device of the clinical gripper for digestive endoscopy is placed between two clamping plates 909. By rotating threaded rods 906 and 907, the two clamping plates 909 are brought closer together to clamp and fix the device. When the device is too low, rotating rod 801 is rotated, which drives the conical transmission wheel 802 to rotate. The rotation of the conical transmission wheel 802 drives the conical driven wheel 803 and threaded rod 804 to rotate, causing the lifting sleeve 805 to move vertically upward. This, in turn, drives the mounting base 901 and the device to move vertically upward, thereby adjusting the device to a suitable height for medical staff to view without affecting subsequent operations.

[0037] When the position of medical staff changes, making it difficult to observe the equipment, the mounting base 901 is pushed upward, which causes the movable sleeve 902 and the first gear 904 to move upward, so that the first gear 904 does not mesh with the second gear 905. At this time, the mounting base 901 can be rotated laterally, and then the equipment can be rotated laterally to an angle that is easy to view, making it convenient for medical staff to view and operate.

[0038] If the device needs to be adjusted laterally, first press the movable rod 201 downward by pressing the protrusion 211, so that the movable rod 201 drives the trapezoidal block 202 to move downward, pushing the two wedge blocks 204 and the two L-shaped limiting tooth plates 205 to both sides, so that the two L-shaped limiting tooth plates 205 lose the limiting effect with the gear 206. At the same time, the locking block 203 at the upper end of the trapezoidal block 202 also moves out of the slot 13. At this time, the support column 4 can be moved horizontally to the right, so that the device held by the clamping plate 909 can be closer to the medical staff, avoiding the device being too far away and affecting the viewing effect.

[0039] When not in use, first restore the mounting base 901 and support column 4 to their initial use state. Then, pull the right-side lever 702 forward, causing the right-side cross-shaped insert 705 to move out of the right-side rotating support rod 18. At this point, the rotating plate 6 can be screwed into the horizontal plate 5 for storage. Then, pull the left-side lever 702 forward, causing the left-side rotating support rod 18 to lose its limiting and fixing effect. At this point, the horizontal plate 5 can be rotated and folded to fit against the support column 4. Finally, press the movable rod 201 by pressing the protrusion 211, causing the L-shaped limiting tooth plate 205 to lose its limiting effect on the gear 206. Then, rotate the support column 4 to rotate it to the upper end of the base 1, completing the storage and folding of the support column 4, thereby reducing the overall space occupied by this device.

These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification.
