The actions of the three elastic arms are synchronous, namely the three elastic arms are unfolded or closed at the same time, and when the three elastic arms are closed at the same time, a containing space for containing a cutter is formed. Of course, the receiving space may be completely closed or partially closed, but at least the cutting position of the knife, i.e. the knife edge, may be spaced from the intestinal esophageal wall by the resilient arm when the knife edge is in the receiving space. In this embodiment, a completely closed manner is preferable. The outer surface of the tip of the resilient arm has a certain roughness to allow the tip of the resilient arm to stably abut against the wall of the intestinal esophageal when the resilient arm is deployed. When the elastic arms are unfolded, certain gaps exist between the adjacent elastic arms so as to allow an operator to clamp at least part of the object to be detected through the gaps.
The compression spring 32 is sleeved on the outer side wall of the traction piece 33, one end of the compression spring 32 is contacted with one end surface of the annular step groove 11 close to the handle component, and the other end of the compression spring 32 is contacted with the other side surface of the annular sheet; the other side surface of the circular ring piece is provided with a hook part 34, and the other end of the compression spring is connected with the hook part on the other side surface of the circular ring piece. The number of the hook parts is at least three, and the hook parts are distributed on the circumferential direction of the ring pieces at equal intervals. The opening of the hook part is arranged towards the center of the circular ring piece.
Through set up hook portion and compression spring other end at ring piece another side and be connected, realize the fixed connection of the two, under the circumstances of guaranteeing structural stability, reduced the assembly degree of difficulty. The number of the hook parts is at least three, so that the connection strength can be ensured; the equal interval distribution can ensure the stress balance in the circumference of the ring piece, so that the compression spring and the hook part are not easy to damage. Through the structural design, the compression spring can be effectively prevented from escaping.
The other end of the traction piece 33 is fixedly connected with the handle component.
Through the structure design, compression spring's elasticity direction is limited in between the terminal surface that ring piece another side and cyclic annular step groove are close to handle component, because draw a one end and be connected with the ring piece, the other end is connected with handle component, when operating handle component (pulling to the handle direction) promptly, draw a can drive the ring piece and remove towards handle direction, compression spring compressed this moment, and the elastic arm receives inside the accomodating of inside wall influence, the common cladding of a plurality of elastic arm cutter, the elastic arm is the petal leaf form, and a plurality of elastic arm laminating each other form airtight cavity (certainly also can not be totally airtight, decide depending on the circumstances) when closed, and the elastic arm at this moment also has the restoring force of expansion, and when releasing handle component promptly, the ring piece resumes to the original position under compression spring's elasticity effect, and the elastic arm outwards expands and forms open type cavity. This structure is when aiming at examining the thing, operating handle component for examine the thing by the cladding in the airtight cavity that forms, at this moment, the drive cutter carries out crushing operation to examining the thing, can follow the biopsy hole after smashing and take out. It should be noted that, in the crushing process, the elastic arm forms a protective cover for the cutter, so as to avoid damage to the inner wall of the detection channel, and as the formed closed cavity is formed, the crushed fine particles cannot fall out, so that the cleaning and diagnosis of the detection channel are facilitated. Through the structural design, when the elastic arm rotates on the circular ring piece, the corresponding restoring force is generated due to the existence of the torsion spring, so that the elastic arm is accommodated when being matched with pulling, and the elastic arm is unfolded when being loosened.
