Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example (b):

referring to fig. 1 and 2, the utility model discloses an endoscope biopsy forceps with protection architecture, including the sampling forceps body 1, the sampling forceps body 1 includes binding clip 2 and core 3, and the axle center direction runs through there is cable 33 in the core 3. The tong head 2 comprises two shearing knives which are hinged and a connecting rod which is hinged with the two shearing knives, and one end of the connecting rod, which is far away from the shearing knives, is connected with a stay cable 33. The other end of the cable 33 is connected with a pad 34, the pad 34 is located at one end of the core body 3 far away from the clamp head 2, and the periphery of the pad 34 is abutted against the inner wall of the core body 3. The end face of the cushion block 34 far away from the stay 33 is connected with a pull rod 35, the other end of the pull rod 35 is connected with a secondary snap ring 36, and one end of the core body 3 close to the pull rod 35 is provided with a supporting plate 37. The supporting plate 37 is supported by one hand of an operator, and the secondary retaining ring 36 is pulled by the other hand of the operator, so that the purpose of pulling the pull rope 33 is achieved, the effect of closing the forceps head 2 is achieved, and the forceps head 2 can sample lesion tissues. In the operation process, the periphery of the cushion block 34 is tightly combined with the core body 3, and the friction force between the periphery and the inner wall of the core body 3 reduces the situation that the cushion block 34 moves without external force.

Referring to fig. 1 and 2, core 3 overcoat is equipped with protective sheath 4, is provided with two grooves 32 that slide on the core 3, and the inner wall that protective sheath 4 and core 3 cup jointed is provided with two and is located sliding block 43, and when core 3 runs through in protective sheath 4, two grooves 32 that slide are in sliding block 43 respectively for core 3 forms the sliding connection relation with grooves 32 that slide. The protection head 41 is arranged at one end, close to the forceps head 2, of the protection sleeve 4, the mounting end 42 is arranged at one end, far away from the forceps head 2, of the protection sleeve 4, the protection head 41 is made of soft materials, in the embodiment, the protection head 41 is made of medical plastics, and a chamfer is arranged at the end, far away from the mounting end 42, of the protection head 41. The protection head 41 made of soft material has certain deformation capacity, so that the sliding block 43 can be installed in the sliding groove 32, the forceps head 2 is in an original state and is positioned in the protection head 41 in the process of extending the sampling forceps body 1 into the pathological change position, and the condition that the part of the forceps head 2 extends into the process to cause damage to human tissues is reduced. When the forceps head 2 extends into the focus position, the protective sleeve 4 is moved through external force, so that the forceps head 2 extends out of the protective head 41, the secondary retaining ring 36 is pulled through external force, the forceps head 2 is closed through the pull rope 33, and the purpose of sampling tissues at the focus position is achieved.

Referring to fig. 1 and 2, the mounting end 42 is connected with a sliding ring 5, the sliding ring 5 comprises a first-stage body 52 and a second-stage body 53 which are detachably connected, the first-stage body 52 and the second-stage body 53 are semi-cylindrical, a clamping block 54 and a clamping groove 55 are respectively arranged on the first-stage body 52 and the second-stage body 53, and when the clamping block 54 is clamped with the clamping groove 55, the first-stage body 52 and the second-stage body 53 are connected to form the overall cylindrical sliding ring 5. In this embodiment, the mounting end 42 is in threaded connection with the sliding ring 5, and when the primary body 52 is connected with the secondary body 53, the mounting end 42 is connected with the sliding ring 5, so that the primary body 52 and the secondary body 53 can be further locked, and the situation that the primary body 52 is separated from the secondary body 53 due to external force is reduced. The relative inner wall of the first-level body 52 and the second-level body 53 is provided with a groove, when the first-level body 52 and the second-level body 53 are connected, the two grooves are spliced to form a limiting groove 51, and the length of the groove opening is the length of the limiting groove 51. The core body 3 is provided with a snap ring 31, the snap ring 31 is positioned in the limiting groove 51, the circumferential wall of the snap ring 31 is provided with a rubber ring (not shown in the figure), the rubber ring is abutted against the limiting groove 51, and the thickness of the snap ring 31 is smaller than the length of the limiting groove 51. In this embodiment, the sum of the thickness of the snap ring 31 and the length of the binding clip 2 is equal to the length of the limiting groove 51, the slip ring 5 is moved by external force, the slip ring 5 drives the protective sleeve 4 to move, and when the slip ring 5 is moved, the snap ring 31 can stretch the binding clip 2 connected with the core body 3 out of the protective sleeve 4 when moving in the limiting groove 51. The first-stage body 52 and the second-stage body 53 are respectively provided with a first-stage retaining ring 56, so that the hand of an operator can move the sliding ring 5 by virtue of force.

The implementation principle of the above embodiment is as follows: when the endoscope living body sampling forceps are operated, the sampling forceps body 1 is stretched into the body of a patient, and the stretching is stopped when the sampling forceps body reaches the focus position. The first-stage snap ring 56 is held by two fingers of one hand, and the core body 3 is fixed by the other hand. By applying an external force to the first-stage retaining ring 56 toward the second-stage retaining ring 36 to move the slip ring 5, the slip ring 5 drives the protective sleeve 4 to move toward the second-stage retaining ring 36, and the tong head 2 extends out of the protective head 41. The position of the forceps head 2 is adjusted, so that two shearing knives of the forceps head 2 are aligned to the pathological tissue, one hand is used for holding the core body 3, the other hand is used for buckling the second-stage buckle 36, the core body 3 is kept still, the second-stage buckle 36 is pulled, the pull cable 33 is pulled, the forceps head 2 is closed through the pull cable 33, and the pathological tissue is taken down. The sampling forceps body 1 is held by hand, and the sampling forceps body 1 is moved out of the patient body for a part of distance. Remove the sliding ring 5 again, stretch into protection head 41 with binding clip 2 again in, reduce and move out sampling forceps body 1 in-process, the operator hand loosens, and the condition that pathological change tissue was lost, simultaneously, reduces sampling forceps body 1 and retrieves the in-process, and binding clip 2 stabs the condition that patient's tissue.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
