DETAILED DESCRIPTION
[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.
[0027] Example 1
[0028] The present invention provides a digestive tract tumor biopsy sampler, such as Figures 1 to 6 As shown, it includes: an operating handle 1, a coil spring rod 2 is fixedly installed at the bottom end of the operating handle 1, a metal sleeve 3 is fixedly installed at the bottom end of the coil spring rod 2, a moving ring 4 is slidably connected to the outside of the operating handle 1, a quantitative adjustment component 5 is fixedly installed at the bottom end of the moving ring 4, the quantitative adjustment component 5 includes a support member 53 slidably connected to the bottom end of the moving ring 4, a positioning rod 54 is fixedly installed at the middle of the bottom end of the moving ring 4, a connecting rod 55 is fixedly installed at the bottom end of the positioning rod 54, an arc plate 56 is fixedly installed on the outside of the connecting rod 55, and a curved hook 57 is fitted and connected to one end surface of the arc plate 56.
[0029] like Figure 3 and Figure 4 As shown, one side of the top end of the support member 53 is rotatably connected to a threaded rod 51 through a bearing, and a limiting column 52 is embedded and installed at a position of the top end of the support member 53 away from the outer side of the threaded rod 51. The limiting column 52 is slidably connected to the inside of the moving ring 4, and the threaded rod 51 is connected to the inside of the moving ring 4 through a thread, and is used to adjust the position of the support member 53, thereby changing the difficulty of adjusting the position of the support member 53, thereby adjusting the distance between the support member 53 and the bottom end of the moving ring 4, and fixing the adjusted distance.
[0030] like Figure 3 and Figure 4 As shown, a spring rod 58 is fixedly installed in the middle of the inner wall of the hook 57, and the bottom end of the spring rod 58 is fixedly connected to the bottom end of the inner wall of the metal sleeve 3, which can facilitate driving the hook 57 to reset and change the difficulty of resetting the hook 57.
[0031] like Figure 3 and Figure 4 As shown, the connecting rod 55 passes through the hook 57, and a fitting groove is provided on one end face of the hook 57. One end of the arc plate 56 fits with the inner wall of the fitting groove, which facilitates the movement between the arc plate 56 and the hook 57, changes the difficulty of movement between the arc plate 56 and the hook 57, and can limit the arc plate 56, changing the difficulty of limiting the arc plate 56.
[0032] like Figure 5 and Figure 6 As shown, a limit assembly 6 is fixedly installed inside the moving ring 4, and the limit assembly 6 includes a gear 64 rotatably connected to the inside of the moving ring 4, a sawtooth bar 68 is meshingly connected to the outer side of the gear 64, and the sawtooth bar 68 is fixedly installed on the inner wall of the operating handle 1, and a triangle bar 63 is slidably connected to the outer side of the sawtooth bar 68 near the center point of the moving ring 4, which can facilitate the fixing of the gear 64, thereby fixing the moving ring 4, and changing the difficulty of fixing the moving ring 4.
[0033] like Figure 5 and Figure 6 As shown, both end faces of the triangular bar 63 are provided with rounded corners, an extrusion rod 61 is welded to one end face of the triangular bar 63, the extrusion rod 61 is slidably connected to the inside of the movable ring 4, and a spring column 62 is clamped and installed at one end of the extrusion rod 61, which is convenient for driving the movement of the extrusion rod 61, changing the difficulty of moving the extrusion rod 61, and facilitating the resetting of the extrusion rod 61, changing the difficulty of resetting the extrusion rod 61, and further facilitating the limiting of the gear 64.
[0034] like Figure 5 and Figure 6 As shown, one end of the spring column 62 is clamped and installed inside the moving ring 4. A square hole is opened inside the moving ring 4 corresponding to one end of the extrusion rod 61, which is used to limit the extrusion rod 61, thereby changing the difficulty of limiting the extrusion rod 61 and preventing the extrusion rod 61 from deviating when moving.
[0035] like Figure 5 and Figure 6As shown, a plurality of guide grooves 65 are provided on one end face of the gear 64, an airbag 66 is equidistantly embedded inside the gear 64, a rubber pad 67 is bonded to one end of the airbag 66, an air intake pipe 69 is clamped and installed on one end of the airbag 66, one end of the air intake pipe 69 passes through the gear 64 and is located inside the guide groove 65, so as to facilitate inflating the inside of the airbag 66, so that the airbag 66 expands slightly. When the airbag 66 expands slightly, the rubber pad 67 is driven to approach the moving ring 4, thereby increasing the squeezing force of the rubber pad 67 on the moving ring 4, and then increasing the friction between the rubber pad 67 and the moving ring 4, thereby reducing the rotation speed of the gear 64.
[0036] Working principle: During the actual use of the device, the user rotates the threaded rod 51, and the threaded rod 51 drives the support member 53 to move at the bottom end of the moving ring 4 when rotating, so as to adjust the downward movable spacing of the moving ring 4 on the outer side of the operating handle 1, and then adjust the moving spacing of the arc plate 56, so as to adjust the spacing between the arc plate 56 and one end surface of the hook 57, and then adjust the number of living body samples taken inside the hook 57, which helps to ensure the representativeness of the sample, improve the effectiveness and accuracy of the experiment, and can adapt to various application needs, whether it is micro or large-scale sampling, it can be flexibly responded to, and adjusting the spacing can better protect the sample structure, reduce damage, and further improve the sample quality, and at the same time help to achieve standardized operation and reduce the impact of personal operation differences;
[0037] Then the staff holds the moving ring 4. At this time, when holding, since the staff holds the squeezing rod 61, the squeezing rod 61 squeezes the spring column 62 when holding, so that the spring column 62 is compressed. When the spring column 62 is compressed, it drives the triangular bar 63 to move outside the gear 64, so that the dead gear 64 is unlocked, thereby achieving the purpose of unlocking the moving ring 4, so that the moving ring 4 can be displaced on the operating handle 1, preventing the problem of the moving ring 4 being displaced due to the staff accidentally touching the moving ring 4, thereby making the moving ring 4 more stable during the placement process, and further improving the safety of the sampler during operation;
[0038] At this time, when the moving ring 4 moves, the connecting rod 55 is driven to move by holding the positioning rod 54, and when the connecting rod 55 moves, the arc plate 56 is driven to enter the predetermined position. Then the staff holds the operating handle 1, and puts the spiral spring rod 2 and the metal sleeve 3 into the patient's digestive tract, and then pulls the moving ring 4 to rise. At this time, when the moving ring 4 rises, the arc plate 56 is driven to move, and negative pressure is generated when the arc plate 56 moves, so that the active substance is sucked into the hook 57, and when the moving ring 4 moves, the gear 64 is driven to rotate. When the gear 64 rotates, the external gas enters the air inlet pipe 69 along the guide groove 65 through the guide groove 64, and the gas expands the airbag 66. The expanded airbag 66 adjusts the extrusion force between the rubber pad 67 and the moving ring 4, thereby changing the moving speed of the moving ring 4, further reducing the suction force of the arc plate 56 on the living body, thereby preventing the problem of discomfort to the patient caused by the large suction force, and further improving the comfort of the patient during the living body sampling process;
[0039] Finally, when the arc plate 56 moves to fit the hook 57, the arc plate 56 continues to move, and the arc plate 56 drives the hook 57 to move. When the hook 57 moves, the living body enters the fitting groove of the hook 57. With the positioning of the arc plate 56, the sampling amount of the living body is increased, and the sampling amount can be effectively quantified, changing the difficulty of quantification.
[0040] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
