Abstract
The utility model discloses cervical biopsy forceps, which comprise a fixed handle, a free handle, an upper forceps head, a traction bar and a hollow outer tube, the tail end of the outer tube is arranged on the fixed handle, the head end of the outer tube is fixedly provided with a lower forceps head, the fixed handle is hinged to the free handle, the traction bar penetrates and is inserted into the outer tube, and one end of the traction bar is movably connected to the free handle while the other end is hinged to the upper forceps head which is hinged onto the lower forceps head. By applying the cervical biopsy forceps, the gap in the surface of an instrument is reduced, the human tissue or mucus is prevented from entering the biopsy forceps, the failure probability of sampling is lowered, and the success rate of one-time operation is improved.
Description
Technical field
This utility model relates to a kind of cervical biopsy pincers, belongs to technical field of medical instruments.
Background technology
At present, cervical biopsy is to be applicable to be suspected to have cervical cancer or chronic specificity inflammation must be the patient who further clarifies a diagnosis as tuberculosis etc., and cervical biopsy pincers are so that its sampling amount is large, biopsy accuracy rate is high and patient is injured to little advantage and use in a large number in clinical.But existing product mostly is use repeatly, there is following technological deficiency: existing repeated product appearance exists gap, in operating process, tissue and human body mucus more easily enter its gap and can cause stuck biopsy forceps in use procedure, cause biopsy failure, increased patient's misery, in gap, mucus is cleaned difficulty, cleaning dirty in the clinical middle risk that has cross infection.
Summary of the invention
Technical problem to be solved in the utility model is the defect that overcomes prior art, a kind of cervical biopsy pincers are provided, and it has reduced the gap on apparatus surface, avoids tissue or mucus to enter biopsy forceps, reduced and sampled failed probability, improved the success rate of disposable operation.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of cervical biopsy pincers, the outer tube that comprises fixed handle, flexible handle, upper grip head and draw bar and hollow, the tail end of outer tube is arranged on fixed handle, and the head end of outer tube is fixed with lower pliers head, and fixed handle and flexible handle are hinged, described draw bar interts within the outer tube, and its one end is flexibly connected with flexible handle, its other end and upper grip head are hinged, and upper grip head is also hinged on lower pliers head.
Further for fixed handle can be automatically reset after closure at flexible handle, between fixed handle and flexible handle, be provided with the back-moving spring group that fixed handle and flexible handle are resetted, back-moving spring group comprises the first reed of being arranged on fixed handle and is arranged on the second reed on flexible handle, and the first reed overlaps mutually with the second reed.
The mode that further provides a kind of draw bar to be flexibly connected with flexible handle, on flexible handle, be fixed with holding piece, on described draw bar, be provided with two clamping nuts, and groove between formation activity between clamping nut, described holding piece is clamped on draw bar on the position between groove between activity.
Further, in order to reduce costs, flexible handle and/or fixed handle are made by macromolecular material.
Further, described macromolecular material is ABS plastic or PP material or PE material or PA material or PC material.
Further, outer tube is made by stainless steel material.
Adopted after technique scheme, this utility model utilizes closed fixed handle and flexible handle, drive draw bar travels forward, thereby cause upper grip head to incision until suit to cut wanted biopsy with lower pliers head, easy to operate accurate, improve the success rate of disposable operation, reduced patient's misery, improved work efficiency and success rate of operation; This utility model is by being used the outer tube structure of hollow, the namely outer tube-surface that stretches into partly of product does not have gap, its structure is simpler, stable, without tissue, mucus in repeated product, enter the possibility in appearance gap, greatly reduced and sampled failed possibility, and reduced the misery of patient in product use procedure.
Accompanying drawing explanation
Fig. 1 is the structural representation of cervical biopsy pincers of the present utility model.
The specific embodiment
For content of the present utility model is more easily expressly understood, according to specific embodiment also by reference to the accompanying drawings, this utility model is described in further detail below,
As shown in Figure 1, a kind of cervical biopsy pincers, it comprises the outer tube 4 of fixed handle 1, flexible handle 2, upper grip head 8 and draw bar 6 and hollow, the tail end of outer tube 4 is arranged on fixed handle 1, and the head end of outer tube 4 is fixed with lower pliers head 5, and fixed handle 1 is hinged with flexible handle 2, draw bar 6 interts in outer tube 4, and its one end is flexibly connected with flexible handle 2, its other end and upper grip head 8 are hinged, and upper grip head 8 is also hinged on lower pliers head 5.
For fixed handle 1 can be automatically reset after closure at flexible handle 2, as shown in Figure 1, between fixed handle 1 and flexible handle 2, be provided with the back-moving spring group that fixed handle 1 and flexible handle 2 are resetted, back-moving spring group comprises the first reed 3-1 of being arranged on fixed handle 1 and is arranged on the second reed 3-2 on flexible handle 2, and the first reed 3-1 overlaps mutually with the second reed 3-2.
On flexible handle 2, be fixed with holding piece, be provided with two clamping nuts on draw bar 6, and groove between formation activity between clamping nut, holding piece is clamped on draw bar 6 on the position between groove between activity.The mode that this structure provides a kind of draw bar to be flexibly connected with flexible handle, but the mode that draw bar is flexibly connected with flexible handle is not limited to this.
Operation principle of the present utility model is as follows:
This utility model utilizes closed fixed handle 1 and flexible handle 2, drive draw bar 6 to travel forward, thereby cause upper grip head 8 to incision until suit to cut wanted biopsy with lower pliers head 5, easy to operate accurate, improved the success rate of disposable operation, reduce patient's misery, improved work efficiency and success rate of operation; This utility model is by being used the outer tube structure of hollow, the part that stretches into of product does not namely have gap in outer tube 4 surfaces, its structure is simpler, stable, without tissue, mucus in repeated product, enter the possibility in appearance gap, greatly reduced and sampled failed possibility, and reduced the misery of patient in product use procedure.
Above-described specific embodiment; technical problem, technical scheme and beneficial effect that this utility model is solved further describe; institute is understood that; the foregoing is only specific embodiment of the utility model; be not limited to this utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
