In this embodiment, the second transmission portion and the limit slider may be connected by a bolt. However, the present embodiment should not be limited thereto. Those skilled in the art can flexibly select the materials according to the needs.
It should be noted that, in order to facilitate the reciprocating motion of the limiting slider around the limiting hole, in this embodiment, the limiting hole may be a bar-shaped limiting hole, and of course, the limiting hole may also be a limiting hole with another shape, which should not be limited by this embodiment, and will not be described in detail herein.
In order to enable the head rotatable biopsy forceps to accurately detect the size of the detected tissue, a user can directly read the size of the detected tissue through the sliding distance of the limiting sliding block in the limiting hole, in the embodiment, scale marks can be arranged on two sides of the limiting hole, and a preset proportional relation is formed between the opening and closing angle of the forceps head and the scale range pointed by the limiting sliding block on the limiting hole.
For example, in this embodiment, the range of the scale indicated by the sliding of the limiting slider in the limiting hole may have a preset proportional relationship with the opening/closing angle range of the pliers head being 0 ° to 120 °, where the preset proportional relationship may be: 5:1. it should be noted that the scale marks arranged on both sides of the limiting hole should be corresponding to the size of the tissue to be measured, and may be appropriately larger than the size of the tissue to be measured. However, the present embodiment should not be limited to this, and the range of the scale indicated by the sliding of the limiting slider in the limiting hole may also be a preset proportional relationship with the opening and closing angle range of the clamp head being 30 ° to 160 °, where the preset proportional relationship may be: 6:1. the implementation should not be limited by the angle range and the preset proportional relationship, and a person skilled in the art can flexibly select the range of the opening and closing angle of the clamp head and the preset proportional relationship according to the requirement.
Through the above, it is not difficult to find that, a person skilled in the art can flexibly set a proportional relationship between a range of the scale indicated by the sliding of the limiting slider in the limiting hole and an opening and closing angle range of the clamp head according to needs, and this embodiment is not described in detail herein.
In addition, the first transmission part and the second transmission part are important parts of the head rotatable biopsy forceps in the whole detection process, so that the first transmission part and the second transmission part are particularly easy to wear in the use process, the service life is relatively short, and in order to prolong the service lives of the first transmission part and the second transmission part, in the embodiment, the first transmission part and the second transmission part can be steel ropes. However, the present embodiment should not be limited to this, and the first transmission portion and the second transmission portion may be made of other materials. The material of the first transmission part and the second transmission part can be flexibly selected by a person skilled in the art.
In order to satisfy the ergonomic design and facilitate the holding of the user, in the present embodiment, the holding portion may be in a cylindrical shape, but the present embodiment should not be limited thereto, and the holding portion may be in other shapes, which are not described herein.
It should be noted that, in the present embodiment, the first movable portion may be a worm wheel, and the second movable portion may be a worm engaged with the first movable portion, but the present embodiment should not be limited thereto.
In the in-process of the rotatable biopsy forceps with the head in actual use, on one hand, the head swing is realized through rotating the first control part, so that the sampling is more convenient, the problem of dead zone of the sampling is solved, and on the other hand, the opening and closing of the forceps head are realized through the second control part, so that the tissue to be measured can be accurately clamped.
It will be understood by those of ordinary skill in the art that the foregoing embodiments are specific examples of carrying out the application and that various changes in form and details may be made therein without departing from the spirit and scope of the application.
