Description
Technical field
This utility model relates to a kind of type self-destroyed cervix uteri biopsy forceps, just relates to specifically after an a kind of patient uses to reuse cervix uteri biopsy forceps again, belongs to medical supplies utensil technical field.
Background technology
Now widely used cervix uteri biopsy forceps mostly is stainless steel structure, after use, through sterilization, can be used again, if but sterilization is incomplete, easily to patient, bring cross infection, if virus morphs, may there is problem that cannot thorough disinfection in existing sterilization method.On the other hand, along with social development, people more and more pay attention to invention and the use of disposable medical instrument, also have some disposable cervix uteri biopsy forcepss on market, but due to complex process, production cost is high, and can not be widely used, although also there is portioned product cheap, but can not well accomplish disposable use, in some low developed areas, often again reused, to patient, bring more safety problems.For this reason, the inventor has invented type self-destroyed cervix uteri biopsy forceps, to make up market deficiency.
Utility model content
The purpose of this utility model be to provide a kind of novel structure use reliable, for reusable type self-destroyed cervix uteri biopsy forceps again after a patient.
The purpose of this utility model is to realize like this, it is mainly by connecting rod (1), caliper (6), upper jaw (7), lower jaw (8), spring (9), spanner (10) forms, wherein: spanner (10) links mutually with caliper (6), between spanner (10) and caliper (6), be connected to spring (9), 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), ratchet bar (61) clamping on the upper ratchet (31) of ratchet (3) and caliper (6), ratchet bar (51) clamping on lower ratchet (32) and 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.
This utility model compared with prior art, safe and reliable, easy to use, and production cost is low, is applicable to producing in enormous quantities.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is jaw open mode structural representation of the present utility model.
Fig. 3 is the local structure for amplifying schematic diagram of this utility model.
Fig. 4 is that this utility model is used to complete rear local structure for amplifying schematic diagram.
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.
The specific embodiment
Below in conjunction with drawings and Examples, this utility model is further illustrated:
Referring to accompanying drawing, this utility model it mainly by connecting rod 1, caliper 6, upper jaw 7, lower jaw 8, spring 9, spanner 10 forms, wherein: spanner 10 links mutually with caliper 6, between spanner 10 and caliper 6, be connected to spring 9, caliper 6 left ends are 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 on caliper 62 is blocked, limited block 4 is located between motion block 5 and caliper 6, and be connected with ratchet 3, the upper ratchet 31 of ratchet 3 and ratchet bar 61 clampings on caliper (6), 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 three points of live body sampling, 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, now the upper ratchet 31 of ratchet 3 and lower ratchet 32 all in not with the interlocking pattern of ratchet bar 61 and ratchet bar 51; Arrive after sampling point, hold with a firm grip spanner 10 and caliper 6, under the effect of stop nut 11, shift fork 2 drivening rods 1 move right, and upper jaw 7 slowly opens, and now, motion block 5 moves right, the lower ratchet 32 of ratchet 3 and first interlock of ratchet bar 51; Unclamp spanner 10 and caliper 6, under the effect of spring 9, shift fork 2 drivening rods 1 are to left movement, upper jaw 7 and lower jaw 8 interlocks, complete sampling for the first time, now due to ratchet 32 first tooth interlock with ratchet bar 51, thereby drive limited block 4 to left movement, when upper jaw 7 and lower jaw 8 interlock, the upper ratchet 31 of ratchet 3 and the lucky interlock of first tooth of ratchet bar 61, after having sampled for the first time, the upper ratchet 3 of ratchet 3 and lower ratchet 32 are all in first tooth interlocking pattern with ratchet bar 61 and ratchet bar 51.
While again sampling, repeat above-mentioned action, the upper ratchet of ratchet 3 31 and lower ratchet 32 successively with 4 tooth interlocks successively of ratchet bar 61 and ratchet bar 51; When the present invention completes after use, limited block 4 slides into Far Left, the upper ratchet 31 of ratchet 3 and lower ratchet 32 respectively with the 4th tooth interlock of ratchet bar 61 and ratchet bar 51, caliper confined planes 62 butts on the confined planes 41 of limited block 4 and caliper 6 now, under effect at this aspect two, type self-destroyed cervix uteri biopsy forceps, in stuck state, cannot be used by secondary.
