Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
It referring to Fig.1, is a kind of cervical biopsy forceps with retaining mechanism disclosed by the utility model, sample pickup tongs is whole
Body is in gun shaped structure, including the upper push-rod 1 made of steel material, lower push-rod 2, front hand grip 3, back handle 4, upper grip head 5, lower pincers
First 6.Upper push-rod 1 is slidably arranged on lower push-rod 2, and 2 end of lower push-rod is fixedly connected with back handle 4, upper push-rod 1 and lower push-rod
2 end is respectively hinged in front hand grip 3；2 front end of lower push-rod is fixedly connected with lower pliers head 6, the front end of upper push-rod 1 and lower push-rod 2
It is respectively hinged on upper grip head 5, elastic element 7 is equipped between front hand grip 3 and back handle 4.
Referring to Fig. 2, elastic element 7 includes the first elastic slice 71 and the second elastic slice being arranged between front hand grip 3 and back handle 4
72, the bottom end of the first elastic slice 71 and the second elastic slice 72 is fixed with front hand grip 3 and 4 inside bolt of back handle respectively, the first elastic slice 71
It is mutually clamped with the top of the second elastic slice 72.
Referring to Figures 1 and 2, back handle 4 is provided with the locking for limiting the folding of upper grip head 5 far from one end of lower pliers head 6
Mechanism 8.Retaining mechanism 8 includes the locking plate 81 being rotatablely connected with back handle 4, and 81 circumferential surface of locking plate is provided with the first non-slip texture
811.The limiting slot 84 being fitted into for locking plate 81 is provided on back handle 4, limiting slot 84 is set as shallow slot mouth, 81 bottom of locking plate
It is overlapped on shallow slot mouth.The middle part of locking plate 81 is rotatablely connected by the shaft 1 and back handle 4 of bolt arrangement, shaft 1
The lateral wall for being axially perpendicular to back handle 4.The radius of locking plate 81 is greater than the spacing of shaft 1 and 1 bottom wall of upper push-rod, lock
One end of tight disk 81 towards upper push-rod 1 is provided with the smooth evacuation slope surface 83 slid for upper push-rod 1, avoids the inclined surface of slope surface 83
It is parallel with the glide direction of upper push-rod 1.When avoiding slope surface 83 and upper push-rod 1 and not contacting, locking plate 81 is towards back handle 4
One end is abutted with upper push-rod 1, and upper grip head 5 is mutually twisted with lower pliers head 6；When avoiding slope surface 83 upward, upper push-rod 1 can be along evacuation
Slope surface 83 does horizontal displacement, realizes that the folding of upper grip head 5 and lower pliers head 6 samples.
Referring to Fig.1, the side that front hand grip 3 and back handle 4 mutually deviate from is respectively arranged with the first hand-held positioning region 31 and
Two hand-held positioning regions 41.First hand-held positioning region 31 includes being arranged in the first of 3 upside of front hand grip to abut column 311 and setting
Curved bend trisection 312 in 3 downside of front hand grip.Second hand-held positioning region 41 includes being arranged in the second of 4 upside of back handle to abut
Column 411 and the second non-slip texture 412 being arranged on back handle 4.It is singlehanded in cervical biopsy forceps sampling process
It is held in the first hand-held positioning region 31 and the second hand-held positioning region 41, so that entire sampling process is solid and reliable, reduces sampling
Slipping phenomenon when operation between sample pickup tongs and hand is easy to sample pickup tongs flexible operating, to reduce pain of the patient in sampling process
It is bitter.
The implementation principle of the present embodiment are as follows: upper push-rod 1, lower push-rod 2 made of steel material, front hand grip 3, back handle 4, on
Binding clip 5, lower pliers head 6 have the advantages that high temperature resistant, easily sterilize, is reusable, reduce resource waste.
When carrying out cervical biopsy, by evacuation 83 turn of slope surface to 81 roof of locking plate.Front hand grip 3 is held with after
Handle 4 presses front and back handle 4 to direction clamping close to each other, and upper push-rod 1 drives upper grip head 5 to downwardly turn over and clamps in realization
First 5 and lower pliers head 6 occlusion sampling.After the completion of sampling, the gripping active force to front and back handle 4 is unclamped, in 71 He of the first elastic slice
Under the elastic-restoring force effect of second elastic slice 72, front hand grip 3 is kept away from the state of back handle 4, and upper grip head 5 is in separate at this time
Cervix living body sample in lower pliers head 6 is taken out, completes entire sampling operation by the open state of lower pliers head 6.
Sample pickup tongs when not used, by after disinfection sample pickup tongs place sterile sealed bag.It at this time can be real by retaining mechanism 8
Existing upper grip head 5 is loaded with the closure that lower pliers head 6 is laminated, to protect upper grip head 5 and lower pliers head 6 injury-free.First one hand is held
It holds and presses front and back handle 4, be engaged so that upper grip head 5 is downwardly turned over lower pliers head 6, at this time the one end of upper push-rod 1 far from upper grip head 5
It is flushed with 2 end of lower push-rod, then turn locking plate 81, so that evacuation slope surface 83 avoids the sliding trajectory of upper push-rod 1, realization pair
The abutting of upper push-rod 1 acts on, so that the closed state of upper grip head 5 Yu lower pliers head 6 is kept, to protect upper grip head 5 and lower pliers head
6, and reduce upper grip head 5 and lower pliers head 6 and cause the possibility accidentally injured to medical worker.
The embodiment of present embodiment is the preferred embodiment of the utility model, and not limitation is originally practical new according to this
The protection scope of type, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by practical
Within novel protection scope.
