Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1-8, the present invention provides a technical solution: a lockable living body sampling forceps comprises a left connecting rod 1, one end of the left connecting rod 1 is fixedly connected with a left connecting part 2, one end of the left connecting part 2 far away from the left connecting rod 1 is fixedly connected with a right forceps head 3, the left connecting part 2 is movably connected with a right connecting part 6 through a connecting rod rivet 4, one end of the right connecting part 6 is fixedly connected with a right connecting rod 5, the other end of the right connecting part 6 is fixedly connected with a left forceps head 7, a movable groove 8 is formed in the left connecting part 2, the left connecting part 2 is movably sleeved with the right connecting part 6 through the movable groove 8, the right connecting part 6 is positioned in the left connecting part 2, the outer wall of the right connecting part 6 is contacted with the wall of the movable groove 8 of the left connecting part 2, the other end of the left connecting rod 1 is fixedly provided with two sleeve ring positions 10, the bottom of the right connecting rod is also fixedly provided with the sleeve position, the other end of the spring 9 is fixedly connected with one side of the bottom of the right connecting rod 5, the spring 9 is positioned above the lantern ring position 10, and the spring 9 is not contacted with the lantern ring position 10.
Specifically, as shown in fig. 7 and 8, a round bulge 13 is formed in the top of the occlusal surface of the right forceps head 3, a groove 11 is formed in the top of the occlusal surface of the left forceps head 7, the round bulge 13 and the groove 11 are matched with each other, in the sampling process, the occlusal position is more fixed, a sample cannot fall off easily, and the phenomenon that the secondary sampling causes low working efficiency is avoided.
Specifically, as shown in fig. 7, 8, the middle part of the occlusal surface of the right forceps head 3 has been seted up and has been well tooth 14, two sides tooth 12 has been seted up to the both sides of the occlusal surface of the left forceps head 7, during the interlock, well tooth 14 corresponds the occlusal surface that there is not the insection in the middle part of the left forceps head 7, two sides tooth 12 corresponds the occlusal surface that there is not the insection in the 3 both sides of the right forceps head, the insection that does not adopt mutual interlock is because the sample of sample all need keep sample itself the most primitive state, the insection of mutual interlock probably can make the sample take place slight change, so adopt an insection coplanar, not only have certain steadiness, and be difficult to damage sample itself.
Specifically, as shown in fig. 1, when the spring 9 is at the original position, no force is applied, and at this time, the right forceps head 3 and the left forceps head 7 are in the engaged state, the left forceps head 7 and the right forceps head 3 of the biopsy forceps are not opened by the non-artificial external force, so that the instrument itself is protected, and in the sampling process, because the left forceps head 7 and the right forceps head 3 are opened to apply tension to both ends of the spring 9, the spring 9 also applies tension to the left connecting rod 1 and the right connecting rod 5, so as to drive the left forceps head 7 and the right forceps head 3 to engage, thereby reducing the artificial force application.
Specifically, as shown in fig. 1 and 2, the left connecting rod 1 and the right connecting rod 5 are consistent in length, and the left connecting rod 1 and the right connecting rod 5 are consistent in thickness, so that the integral appearance is attractive, and the two ends are stressed in a balanced manner.
Specifically, as shown in fig. 4, 7 and 8, the front ends of the right forceps head 3 and the left forceps head 7 are curved, and the top ends of the right forceps head 3 and the left forceps head 7 are arc-shaped, so that the curved forceps heads are more suitable for multi-angle sampling, and the arc-shaped top ends are used for avoiding damage to other parts in the sampling process.
Specifically, as shown in fig. 1, the left binding clip 7 can rotate around the connecting rod rivet 4, the rotation angle is 0-120 degrees, the larger the opening angle of the left binding clip 7 and the right binding clip 3 is, the larger the range of a sample which can be sampled is, and multiple operations are avoided.
The working principle is as follows: when the device is used, fingers of a user are sleeved in the two sleeve ring positions 10, the force is applied and opened, the force is applied to the left connecting rod 1 and the right connecting rod 5, the left connecting rod 1 and the right connecting rod 5 drive the left tong head 7 and the right tong head 3 to open, a sample is clamped, the spring 9 applies force when the left tong head 7 and the right tong head 3 start to open, the force applied by the spring 9 is transmitted to the tong heads through the left connecting rod 1 and the right connecting rod 5 to drive the left tong head 7 and the right tong head 3 to be occluded, the sampling is completed, and when the biopsy forceps are not needed, the biopsy forceps enable the left tong head 7 and the right tong head 3 to be in a closed state all the time due to the elasticity.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
