Description

Soft biopsy forceps

Technical field

This utility model relates to a kind of soft biopsy forceps, and it is mainly used in the human body chemical examination of cutting into slices of the focus of bladder and urethra, belongs to the medical device technology mechanical field.

Background technology

In human body in bladder and the urethra therapeutic process, the internal lesions treatment that can undergo surgery after chemical examination is made a definite diagnosis of must cutting into slices in bladder and the urethra section chemical examination, under cystoscopic effect, needs special-purpose section to chemically examine the apparatus forceps class in the human body.Prior art is to the section chemical examination of human bladder and urethra lesions position, do not have special-purpose section apparatus forceps class, substitute with general tiny type section pincers class, its defective is that the operation application is inconvenient, the effect of influence operation and prolongation operating time do not satisfy ideal surgical effect.

The utility model content

Technical problem to be solved in the utility model is to overcome existing above-mentioned deficiency in the prior art, and a kind of reasonable in design is provided, the soft biopsy forceps that can cut into slices and chemically examine the focus of bladder in the human body and urethra effectively.

This utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of soft biopsy forceps, comprise fixed handle, flexible handle, claw beam, pull bar and clamp, fixed handle is connected by screw with flexible handle, it is characterized in that: it also comprises Connection Block, adapter sleeve, claw beam protective sleeve, draw-bar seat, clamp seat and brace; Described Connection Block is fixed on the fixed handle, and adapter sleeve is fixed on the Connection Block, and claw beam is fixed on the adapter sleeve, and the claw beam protective sleeve is inserted in claw beam; Two clamps are fixed on the clamp seat, and clamp seat and claw beam are fixed; Two clamps all have a bowl type groove, and bowl type groove coincide mutually and is ellipse; The tail end of two clamps is connected with two braces respectively, and the other end of two braces is connected with pull bar; Pull bar penetrates claw beam, passes adapter sleeve and Connection Block; Flexible handle has pull rod slot, and pull bar is provided with draw-bar seat, and draw-bar seat snaps in the pull rod slot; Be with spring on the pull bar, spring is between Connection Block and flexible handle.

This utility model compared with prior art, have following positive effect: reasonable in design, can be effectively to the chemical examination of cutting into slices of the focus of bladder in the human body and urethra, and be difficult for hurting other organs, alleviate patient's misery, well reached the effect of operation.
