Description

Soft biopsy forceps

Technical field

This utility model relates to a kind of soft biopsy forceps, and it mainly is to the chemical examination of cutting into slices of the intravital lesions position of people, belongs to the medical device technology mechanical field.

Background technology

In people's interior therapeutic process, the chemical examination of must cutting into slices of intravital lesions position, treatment can undergo surgery after making a definite diagnosis.Particularly the tiny organ-tissue of human body (as urethra, bladder, nasal cavity, ear etc.) needs special-purpose section chemical examination apparatus.When prior art is cut into slices chemical examination to the lesions position of the tiny organ-tissue of human body, do not have special-purpose section chemical examination apparatus, can only cut into slices with general tiny type pincers class.Its defective is: operation is used inconvenient, and organ is too small to be difficult to the gripping section, and prolongs operating time, does 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 intravital lesions position of people 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 and flexible handle, it is characterized in that: it also comprises clamp, clamp seat, claw beam, pull bar, claw beam protective sleeve, adapter sleeve, Connection Block, spring, draw-bar seat and brace; Described fixed handle and flexible handle are interconnection; Have pull rod slot on the flexible handle, draw-bar seat is inserted in the pull rod slot; 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; Pull bar is inserted in spring after passing claw beam, adapter sleeve and Connection Block successively, fixes with draw-bar seat again; Spring is between Connection Block and flexible handle; Two clamps are installed on the clamp seat, and the clamp seat is fixed on the claw beam; The head of clamp has a bowl type groove; The tail end of two clamps links to each other with an end of two braces respectively; The other end of two braces is fixed on the pull bar.

The diameter of claw beam described in the utility model is less than 3 millimeters, and its material is a spring material.

This utility model compared with prior art has following positive effect: reasonable in design, claw beam are soft, can be arbitrarily crooked according to the location of the tiny organ-tissue of human body; Easy to use, flexibly movable, good operation effect.

Description of drawings

Fig. 1 is this utility model structural representation front view.

Fig. 2 is the structural representation of a-quadrant among Fig. 1.

Among the figure: 1 clamp, 2 clamp steady pins, 3 braces, 4 clamp seats, 5 claw beams, 6 pull bars; 7 claw beam protective sleeves, 8 adapter sleeves, 9 Connection Blocks, 10 springs, 11 draw-bar seats, 12 screws; 13 fixed handles, 14 flexible handles, 15 brace steady pins, 16 link pins, 17 bowls of type grooves, 18 pull rod slot.

The specific embodiment

Referring to Fig. 1-2, present embodiment mainly is made up of clamp 1, clamp seat 4, fixed handle 13, flexible handle 14, claw beam 5, pull bar 6, claw beam protective sleeve 7, adapter sleeve 8, Connection Block 9, spring 10, draw-bar seat 11 and brace 3.Wherein fixed handle 13 is connected by screw 12 with flexible handle 14; Have pull rod slot 18 on the flexible handle 14, draw-bar seat 11 is inserted in the pull rod slot 18; Connection Block 9 is by being welded on the fixed handle 13, and adapter sleeve 8 is fixed by welding on the Connection Block 9, and claw beam 5 is fixed by welding on the adapter sleeve 8, and claw beam protective sleeve 7 is inserted in claw beam 5 and fixing.Pull bar 6 is inserted in 10 springs after passing claw beam 5, adapter sleeve 8 and Connection Block 9 successively, and fixing with draw-bar seat 11 again, pull bar 6 is an one with draw-bar seat 11; Spring 10 is between Connection Block 9 and flexible handle 13; Be connected by clamp steady pin 2 between two clamps 1 and the clamp seat 4, clamp seat 4 is fixed by welding on the claw beam 5; The head of clamp 1 has when bowl 17, two bowl types of type groove groove 17 clamps and matches each other, and ovalize; The tail end of two clamps 1 links to each other with an end of two braces 3 respectively by brace steady pin 15; The other end of two braces 3 is fixed on the pull bar 6 by link pin 16.

In the present embodiment, the diameter of claw beam 5 is below 3 millimeters and have elasticity, can be arbitrarily crooked according to the location of the tiny organ-tissue of human body, tiny organ-tissue is cut into slices and is chemically examined in the operation in human body, claw beam 5 is smooth in the tiny organ-tissue bend turnover of human body, can never arbitrarily injure the tiny organ-tissue of human body.

During use, by control fixed handle 13 and flexible handle 14, under the effect of

spring

10,1 pair of organella tissue of two clamps is cut into slices and is chemically examined operation.Under the visual field of endoscope, clamp 1 clamps the lesions position sampling of cutting into slices, and can undergo surgery easily.

The material of present embodiment can be used the disinfectant solution irrigation and disinfection for being metal material, also can use high-temperature sterilization.

In addition, need to prove, specific embodiment described in this description, as long as the undeclared concrete shape and size of its part, then this part can be Any shape and the size that adapts with its structure; Simultaneously, the part title of getting also can be different.Allly conceive equivalence or the simple change that described structure, feature and principle are done, be included in the protection domain of this utility model patent according to this utility model patent.
