Description

Technical Field

[0001] The utility model belongs to the technical field of medical instruments, and in particular relates to a locking living body sampling forceps. Background Art

[0002] Sampling forceps are used for tissue sampling. Sampling forceps, biopsy forceps, biopsy puncture forceps, abdominal biopsy forceps, etc. usually have two types: composed of two pieces connected in the middle, with the head as the forceps beak; or composed of a head, a rod and a handle, with the head as a pair of blades with forceps beaks, generally made of stainless steel.

[0003] At present, most of the surgical biopsy forceps available on the market do not have a locking structure. When using such surgical biopsy forceps, medical staff need to exert force for a long time to keep the biopsy forceps stable. However, the hands will become stiff after exerting force for a long time, which is not only harmful to the medical staff themselves, but also affects work efficiency once the sample falls out.

[0026] The utility model provides a lockable living body sampling forceps for further explanation.

[0027] A lockable living body sampling forceps comprises a first clamp body 1, a connecting rivet 3 is movably provided near one end of the top of the first clamp body 1, the first clamp body 1 is rotatably connected to the second clamp body 2 through the connecting rivet 3, the bottoms of the first clamp body 1 and the second clamp body 2 are both fixedly connected to finger rings 4, the inner sides of the tops of the first clamp body 1 and the second clamp body 2 are both fixedly connected to protrusions 5, the inner sides of the tops of the first clamp body 1 and the second clamp body 2 are also provided with grooves 6, and locking components are provided at the bottoms of the first clamp body 1 and the second clamp body 2.

[0028] The locking assembly includes a rack 7, a through groove 8, a reset chamber 9, a sliding shaft 10, a clamping plate 11, a limit plate 12, a spring 13 and a pulling rod 14. The rack 7 is fixedly connected to the inner side of the bottom of the first pliers body 1, a through groove 8 is provided on the inner side of the bottom of the second pliers body 2, and the reset chamber 9 is also fixedly connected to the inner side of the bottom of the second pliers body 2. The sliding shaft 10 is slidably connected inside the reset chamber 9, the clamping plate 11 is fixedly connected to the top of the sliding shaft 10, the limit plate 12 is fixedly connected to the middle position of the sliding shaft 10, a spring 13 is mounted on the outside of the sliding shaft 10 and located between the limit plate 12 and the bottom wall of the reset chamber 9, and a pulling rod 14 is fixedly connected to the bottom of the sliding shaft 10.

[0029] The first pliers body 1 and the second pliers body 2 have the same length.

[0030] The protrusion 5 and the groove 6 on the top of the first pliers body 1 match with those on the top of the second pliers body 2 .

[0031] The rack 7 is arc-shaped, and the tooth groove at the bottom of the rack 7 is a right-angle groove.

[0032] The rack 7 matches the clamping plate 11 .

[0033] The clamping plate 11 and the rack 7 can be plugged together to keep the living body sampling forceps in a clamped state, thereby avoiding long-term exertion of force by medical staff and improving the stability and efficiency of the operation.

[0034] Working principle: When in use, the medical staff puts their fingers into the two finger rings 4, opens the first clamp body 1 and the second clamp body 2, and then uses the top of the first clamp body 1 and the second clamp body 2 to clamp the sample. Through the action of the spring 13, the sliding shaft 10 always maintains an upward force, so that the clamp plate 11 is always in contact with the rack 7. Because the tooth groove at the bottom of the rack 7 is a right-angle groove, there is no obstruction between the first clamp body 1 and the second clamp body 2 when closing, and when opening, the rack 7 limits the clamp plate 11, thereby locking the living body sampling forceps body.

[0035] It should be noted that the standard parts used in this application document can all be purchased from the market, and the specific connection methods of each part are connected by conventional means such as mature bolts, rivets, welding, etc. in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, and no specific description is given here.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
