Abstract
The invention discloses self-destruction cervical biopsy forceps which mainly comprise a connecting rod (1), a forceps body (6), a spring (9) and a lever (10). The lever (10) is hinged to the forceps body (6), the spring (9) is arranged between the lever (10) and the forceps body (6) in a connected manner, a lower jaw (8) is arranged at the left end of the forceps body (6), the connecting rod (1) is arranged on the forceps body (6), an upper jaw (7) is hinged to the left end of the connecting rod (1) and is hinged onto the lower jaw (8), a movable block (5) is fixedly connected to the right end of the connecting rod (1), a shifting fork (2) on the forceps body (6) can be clamped via limiting nuts (11), a limiting stopper (4) is arranged between the movable block (5) and the forceps body (6) and is fixedly connected with a ratchet (3), upper ratchets (31) and lower ratchets (32) of the ratchet (3) are respectively clamped with ratchet bars (61) and ratchet bars (51), and tooth positions of the ratchet bars (51) are symmetric with tooth positions of the ratchet bars (61). Compared with the prior art, the self-destruction cervical biopsy forceps have the advantages of safety, reliability and convenience in use and suitability for mass production.
Description
Technical field
The present invention relates to a kind of type self-destroyed cervix uteri biopsy forceps, just relate to specifically can not reuse cervix uteri biopsy forceps again after an a kind of patient uses, belong to medical supplies fixture technology field.
Background technology
Now widely used cervix uteri biopsy forceps mostly is stainless steel structure, can be used again through sterilization after using, but if sterilization not exclusively, easily brings cross infection to patient, if virus morphs, existing sterilization method may occur cannot the problem of thorough disinfection.On the other hand, along with social development, people more and more pay attention to invention and the use of disposable medical instrument, market also have some disposable cervix uteri biopsy forcepss, but due to complex process, production cost is high, and can not be widely used, although also there is portioned product cheap, but well can not accomplish single use, in some low developed areas, often again reused, brought more safety problems to patient.For this reason, the present inventor has invented type self-destroyed cervix uteri biopsy forceps, to make up market deficiency.
Summary of the invention
The object of this invention is to provide a kind of novel structure uses reliable, for can not reusable type self-destroyed cervix uteri biopsy forceps again after a patient.
The object of the present invention is achieved like this, it is primarily of connecting rod (1), caliper (6), upper jaw (7), lower jaw (8), spring (9), spanner (10) forms, wherein: spanner (10) links mutually with caliper (6), spring (9) is connected between spanner (10) and caliper (6), caliper (6) left end is provided with lower jaw (8), caliper (6) is provided with connecting rod (1), connecting rod (1) left end is hinged with upper jaw (7), and be hinged on lower jaw (8), right-hand member is connected with motion block (5), and by stop nut (11), the shift fork (2) on caliper (6) is blocked, limited block (4) is located between motion block (5) and caliper (6), and be connected with ratchet (3), upper ratchet (31) and ratchet bar (61) clamping on caliper (6) of ratchet (3), lower ratchet (32) and ratchet bar (51) clamping on motion block (5), ratchet bar (51) is symmetrical with the tooth position of ratchet bar (61).
The number of teeth of ratchet bar (51) and ratchet bar (61) is 1-20.
The present invention is compared with prior art, safe and reliable, easy to use, and production cost is low, is applicable to producing in enormous quantities.

In figure: 1, connecting rod, 2, shift fork, 3, ratchet, 31, upper ratchet, 32, lower ratchet, 4, limited block, 41, confined planes, 5, motion block, 51, ratchet bar, 6, caliper, 61, ratchet bar, 62, caliper confined planes, 7, upper jaw, 8, lower jaw, 9, spring, 10, spanner, 11, stop nut.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described:
See accompanying drawing, the present invention it primarily of connecting rod 1, caliper 6, upper jaw 7, lower jaw 8, spring 9, spanner 10 forms, wherein: spanner 10 links with caliper 6 phase, spring 9 is connected between spanner 10 and caliper 6, caliper 6 left end is provided with lower jaw 8, caliper 6 is provided with connecting rod 1, connecting rod 1 left end is hinged with upper jaw 7, and be hinged on lower jaw 8, right-hand member is connected with motion block 5, and by stop nut 11, the shift fork 2 on caliper 6 is blocked, limited block 4 is located between motion block 5 and caliper 6, and be connected with ratchet 3, upper ratchet 31 and ratchet bar 61 clamping on caliper (6) of ratchet 3, lower ratchet 32 is connected with the ratchet bar 51 on motion block 5, ratchet bar 51 is symmetrical with the tooth position of ratchet bar 61, considering that general patient once checks needs live body to sample three points, therefore the number of teeth of ratchet bar 51 and ratchet bar 61 is set to 4.
Before not using, upper jaw 7 and lower jaw 8 are in interlocking pattern, and limited block 4 is in low order end, and now the upper ratchet 31 of ratchet 3 and lower ratchet 32 are all in the interlocking pattern not with ratchet bar 61 and ratchet bar 51; After arriving sampling point, hold with a firm grip spanner 10 and caliper 6, under the effect of stop nut 11, shift fork 2 drivening rod 1 moves right, and upper jaw 7 slowly opens, and now, motion block 5 moves right, and the lower ratchet 32 of ratchet 3 is engaged with first of ratchet bar 51; Unclamp spanner 10 and caliper 6, under the effect of spring 9, shift fork 2 drivening rod 1 is to left movement, upper jaw 7 is engaged with lower jaw 8, complete first time sampling, now because ratchet 32 is engaged with first tooth of ratchet bar 51, thus drive limited block 4 to left movement, when upper jaw 7 is engaged with lower jaw 8, the upper ratchet 31 of ratchet 3 is engaged just with first tooth of ratchet bar 61, after first time has sampled, upper ratchet 3 and the lower ratchet 32 of ratchet 3 are all in first tooth interlocking pattern with ratchet bar 61 and ratchet bar 51.
When again sampling, repeat above-mentioned action, the upper ratchet 31 of ratchet 3 is engaged with 4 teeth of ratchet bar 61 and ratchet bar 51 successively successively with lower ratchet 32; After the present invention completes use, limited block 4 slides into Far Left, the upper ratchet 31 of ratchet 3 and lower ratchet 32 are engaged with the 4th tooth of ratchet bar 61 and ratchet bar 51 respectively, now the confined planes 41 of limited block 4 abuts with the caliper confined planes 62 on caliper 6, under the effect of these two aspects, type self-destroyed cervix uteri biopsy forceps is in stuck state, cannot be used by secondary.
