DETAILED DESCRIPTION OF THE INVENTION

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] Embodiment 1:

[0029] Please refer to Figure 1 - Figure 7 As shown in the figure, a living body sampling and submission device for oncology department includes:

[0030] An operation part for the user to operate and control the sampling and submission device, including an installation shell 1, a fixed handle 2 fixedly installed on the installation shell 1, and a movable handle 3 hinged on the installation shell 1. First elastic pieces 4 that abut against each other are fixedly connected to both the fixed handle 2 and the movable handle 3. A wire winding and unwinding assembly is connected to the end of the installation shell 1 where the movable handle 3 is located, and a first wire 17 is connected through the wire winding and unwinding assembly.

[0031] A telescopic guiding tube is arranged on the installation shell 1, including an outer tube 13 connected to the installation shell 1 and an inner tube 14 slidably connected to the end of the outer tube 13. A first pull rod 20 is slidably connected to the end of the inner tube 14, and the first pull rod 20 is fixedly connected to the first wire 17. A first pull piece 21 is fixedly connected to the end of the first pull rod 20, and a first insertion rod 22 is fixedly connected to the first pull piece 21.

[0032] A sampling part is arranged at the end of the inner tube 14 and is movably connected to the first insertion rod 22.

[0033] As can be seen from the above, by setting the operation part, the telescopic guiding tube and the sampling part, when the user needs to extend or shorten the length between the sampling part and the operation part, and thus adjust the position of the sampling part, the combined length of the inner tube 14 and the outer tube 13 can be slidably adjusted. At the same time, the length of the first wire 17 is adjusted through the wire winding and unwinding assembly, so that the first wire 17 is tightened to adapt to the adjusted combined length of the inner tube 14 and the outer tube 13. When the user needs to take a sample, the user can rotate the movable handle 3 to drive the wire winding and unwinding assembly and the first wire 17 to move. The first pull rod 20 is driven to move through the first wire 17, and then the sampling part is triggered to act through the first pull piece 21 and the first insertion rod 22, and relevant tumor tissue samples are collected through the sampling part.

[0034] Please refer to Figure 1 - Figure 4As shown in the figure, the wire winding and unwinding assembly includes a mounting bracket 5 fixedly installed on the moving handle 3, a short cylinder 6 fixedly installed on one side of the inner wall of the mounting bracket 5, and a wire cylinder 7 sleeved on the short cylinder 6. The first wire 17 is connected to the wire cylinder 7. A connecting bolt 11 is threadedly connected inside the short cylinder 6, and a pressing piece 12 fixedly connected to the connecting bolt 11 abuts against the outer wall of the mounting bracket 5; a toothed ring 8 is fixedly connected to the side wall of the wire cylinder 7, and a gear 9 meshing with the toothed ring 8 is rotatably connected to the side wall of the mounting bracket 5. The gear 9 is fixedly connected with a rotating rod 10 penetrating through the mounting bracket 5; an arc-shaped groove for the connecting bolt 11 and the rotating rod 10 to move is formed in the mounting shell 1.

[0035] As can be seen from the above, the wire cylinder 7 can rotate on the short cylinder 6. The rotating wire cylinder 7 can wind and unwind the first wire 17 wound thereon, thereby adjusting the acting length of the first wire 17. In order to make the first wire 17 taut, the user can rotate the rotating rod 10 and the gear 9 to drive the toothed ring 8 to rotate. The toothed ring 8 drives the wire cylinder 7 to rotate on the short cylinder 6, adjusting the acting length of the first wire 17 to make the first wire 17 taut. Since the first wire 17 needs to move together with the wire cylinder 7, the mounting bracket 5 and the moving handle 3, it is necessary to limit the rotation of the wire cylinder 7 on the short cylinder 6. At this time, the operator can rotate the connecting bolt 11. As the threaded engagement length between the connecting bolt 11 and the short cylinder 6 increases, the pressing piece 12 abuts against the outer wall of the mounting bracket 5, dragging the short cylinder 6 to slide on the connecting bolt 11, thereby making the two sides of the mounting bracket 5 approach. As the two walls of the mounting bracket 5 gradually tighten to clamp the wire cylinder 7, under the action of friction, the rotation of the wire cylinder 7 on the short cylinder 6 can be effectively restricted. When the user rotates the moving handle 3, the moving handle 3 drives the mounting bracket 5 and the wire cylinder 7 to move, thereby driving the first wire 17 to move.

[0036] Please refer to Figure 5 As shown in the figure, a plurality of abutting blocks 15 attached to the inner tube 14 are fixedly connected to the end of the outer tube 13 in an annular array. The outside of the abutting blocks 15 is provided with an arc-shaped protrusion, and a pressing cylinder 16 is threadedly connected to the outer tube 13. When the user adjusts the combined length of the inner tube 14 and the outer tube 13, the pressing cylinder 16 can be rotated to move the pressing cylinder 16 onto the abutting blocks 15. As the pressing cylinder 16 presses the abutting blocks 15 through the arc-shaped surface of the abutting blocks 15, the pressed abutting blocks 15 will closely fit on the inner tube 14, and the friction between the abutting blocks 15 and the inner tube 14 will limit the sliding of the inner tube 14 inside the outer tube 13, ensuring that the combined length of the inner tube 14 and the outer tube 13 remains unchanged.

[0037] Please refer to Figure 1 - Figure 6As shown, the sampling part includes a connector 18 sleeved on the end of the inner tube 14 and a threaded sleeve 19 rotatably connected to the inner tube 14. The threaded sleeve 19 is threadedly connected to the connector 18. Inside the connector 18, a first hinge rod 23 is hinged by a hinge shaft. A first chute 231 for the first plug rod 22 to be inserted and slide is provided on the first hinge rod 23. A first jaw 24 is fixedly connected to the end of the first hinge rod 23. A second elastic piece 232 is fixedly connected between the first hinge rods 23.

[0038] When the user rotates the moving handle 3 to drive the first wire 17 to move, the first wire 17 will drive the first pull rod 20, the first pull piece 21 and the first plug rod 22 to move. The moving first plug rod 22 will slide inside the first chute 231 and drive the first hinge rod 23 to rotate. The rotating first hinge rod 23 compresses the second elastic piece 232 to deform and makes the first jaw 24 bite. A tissue sample is obtained through the biting of the first jaw 24. When the user releases the moving handle 3, the deformed second elastic piece 232 resets and makes the first jaw 24 open again.

[0039] Embodiment 2:

[0040] Please refer to Figure 1 - Figure 7 As shown, a living body sampling and submission device for oncology department includes:

[0041] An operation part for the user to operate and control the sampling and submission device, including an installation shell 1, a fixed handle 2 fixedly installed on the installation shell 1, and a moving handle 3 hinged on the installation shell 1. First elastic pieces 4 that abut against each other are fixedly connected to both the fixed handle 2 and the moving handle 3. The moving handle 3 is connected with a wire winding and unwinding assembly at the end of the installation shell 1 and is connected with a first wire 17 through the wire winding and unwinding assembly;

[0042] A telescopic guiding tube is arranged on the installation shell 1, including an outer tube 13 connected to the installation shell 1 and an inner tube 14 slidably connected to the end of the outer tube 13. A first pull rod 20 is slidably connected to the end of the inner tube 14, and the first pull rod 20 is fixedly connected to the first wire 17. A first pull piece 21 is fixedly connected to the end of the first pull rod 20, and a first plug rod 22 is fixedly connected to the first pull piece 21;

[0043] A sampling part is arranged at the end of the inner tube 14 and is movably connected to the first plug rod 22.

[0044] As can be seen from the above, by providing an operating part, a telescopic guiding tube, and a sampling part, when the user needs to extend or shorten the length between the sampling part and the operating part, and thus adjust the position of the sampling part, the combined length of the inner tube 14 and the outer tube 13 can be adjusted by sliding, and at the same time, the length of the first pulling wire 17 is adjusted by the wire winding and unwinding assembly, so that the first pulling wire 17 is tightened to adapt to the adjusted combined length of the inner tube 14 and the outer tube 13. When the user needs to take a sample, the moving handle 3 can be rotated to drive the wire winding and unwinding assembly and the first pulling wire 17 to move. The first pulling wire 17 drives the first pull rod 20 to move, and then the sampling part is triggered to act through the first pulling piece 21 and the first inserting rod 22, and relevant tumor tissue samples are collected by the sampling part.

[0045] Please refer to Figure 1 - Figure 4 As shown, the wire winding and unwinding assembly includes a mounting bracket 5 fixedly installed on the moving handle 3, a short cylinder 6 fixedly installed on one side of the inner wall of the mounting bracket 5, and a wire cylinder 7 sleeved on the short cylinder 6. The first pulling wire 17 is connected to the wire cylinder 7. A connecting bolt 11 is threadedly connected inside the short cylinder 6, and a tightening piece 12 that abuts against the outer wall of the mounting bracket 5 is fixedly connected to the connecting bolt 11. A toothed ring 8 is fixedly connected to the side wall of the wire cylinder 7, a gear 9 that meshes with the toothed ring 8 is rotatably connected to the side wall of the mounting bracket 5, and the gear 9 is fixedly connected to a rotating rod 10 that penetrates through the mounting bracket 5. An arc-shaped groove for the connecting bolt 11 and the rotating rod 10 to move is formed in the mounting shell 1.

[0046] As can be seen from the above, the wire cylinder 7 can rotate on the short cylinder 6, and the rotating wire cylinder 7 can wind and unwind the first pulling wire 17 wound thereon, thereby adjusting the effective length of the first pulling wire 17. To make the first pulling wire 17 taut, the user can rotate the rotating rod 10 and the gear 9 to drive the toothed ring 8 to rotate. The toothed ring 8 drives the wire cylinder 7 to rotate on the short cylinder 6 to adjust the effective length of the first pulling wire 17 to make the first pulling wire 17 taut. Since the first pulling wire 17 needs to move together with the wire cylinder 7, the mounting bracket 5, and the moving handle 3, the rotation of the wire cylinder 7 on the short cylinder 6 needs to be restricted. At this time, the operator can rotate the connecting bolt 11. As the threaded engagement length between the connecting bolt 11 and the short cylinder 6 increases, the tightening piece 12 abuts against the outer wall of the mounting bracket 5, dragging the short cylinder 6 to slide on the connecting bolt 11, thereby bringing the two sides of the mounting bracket 5 closer. As the two walls of the mounting bracket 5 gradually tighten to clamp the wire cylinder 7, the rotation of the wire cylinder 7 on the short cylinder 6 can be effectively restricted under the action of friction. When the user rotates the moving handle 3, the moving handle 3 drives the mounting bracket 5 and the wire cylinder 7 to move, thereby driving the first pulling wire 17 to move.

[0047] Please refer to Figure 5As shown, a plurality of abutting blocks 15 attached to the inner tube 14 are fixedly connected to the end of the outer tube 13 in an annular array. The outside of the abutting blocks 15 is provided with an arc-shaped protrusion, and an abutting cylinder 16 is threadedly connected to the outer tube 13. After the user adjusts the combined length of the inner tube 14 and the outer tube 13, the abutting cylinder 16 can be rotated so that the abutting cylinder 16 moves onto the abutting blocks 15. As the abutting cylinder 16 presses the abutting blocks 15 through the arc-shaped surface of the abutting blocks 15, the pressed abutting blocks 15 will closely fit on the inner tube 14, and the frictional force between the abutting blocks 15 and the inner tube 14 will limit the sliding of the inner tube 14 inside the outer tube 13, ensuring that the combined length of the inner tube 14 and the outer tube 13 remains unchanged.

[0048] Please refer to Figure 1 - Figure 7 As shown, the sampling part includes a connection head 18 sleeved on the end of the inner tube 14 and a threaded sleeve 19 rotatably connected to the inner tube 14. The threaded sleeve 19 is threadedly connected to the connection head 18. A wire tube 25 is fixedly connected to the end of the connection head 18. A second pull rod 251 is slidably connected to the end of the connection head 18, and a jack for inserting the first insertion rod 22 is provided on the second pull rod 251. A second pull wire 252 located in the wire tube 25 is fixedly connected to the end of the second pull rod 251. A head 26 is fixedly connected to the end of the wire tube 25. A third pull rod 27 connected to the second pull wire 252 is slidably connected inside the head 26. A second pull piece 28 is fixedly connected to the end of the third pull rod 27. A second insertion rod 29 is connected to the second pull piece 28. A second hinge rod 30 is hinged in the head 26 through a hinge shaft. A second sliding groove 31 for slidably inserting the second insertion rod 29 is provided on the second hinge rod 30. A second clamping jaw 32 and a third elastic piece 33 are fixedly connected to the second hinge rod 30.

[0049] As can be seen from the above, when the user rotates the moving handle 3 to displace the first pull wire 17, the first pull wire 17 will drive the first pull rod 20, the first pull piece 21 and the first insertion rod 22 to move. The first insertion rod 22 drives the second pull rod 251 and the second pull wire 252 to move. As the second pull wire 252 moves inside the wire tube 25, the second pull wire 252 will drive the third pull rod 27, the second pull piece 28 and the second insertion rod 29 to move. The moving second insertion rod 29 slides inside the second sliding groove 31 and forces the second hinge rod 30 to rotate and compress the third elastic piece 33, and at the same time makes the second clamping jaw 32 rotate and bite to obtain tissue samples through the rotation and biting of the second clamping jaw 32. When the first pull wire 17 and the second pull wire 252 become loose, the compressed third elastic piece 33 resets to drive the second hinge rod 30 and the second clamping jaw 32 to open again.

[0050] The inner wall of the wire tube 25 fits against the second pulling wire 252, which means that there is a very small gap between the inner wall of the wire tube 25 and the second pulling wire 252. The second pulling wire 252 can slide inside the wire tube 25, and at the same time, it can also prevent the second pulling wire 252 from folding and bending inside the wire tube 25 and losing its function.

[0051] Compared with the sampling part of the first embodiment, the sampling part of the second embodiment is more flexible and can perform sampling inside the bending space. The user can assemble two sampling parts at the end of the inner tube 13 for use according to needs.
