Abstract

The utility model relates to hard foreign body forceps, which are mainly used for clamping foreign bodies at a lesion excision position in a human body and comprise forceps clips, a forceps clip seat, a fixed handle, a movable handle, a forceps rod, a pull rod, a connecting sleeve, a connecting base, a spring and connecting sheets, wherein the fixed handle is connected with the movable handle; the connecting base is fixed on the fixed handle; the connecting sleeve is fixed on the connecting base; the forceps rod is fixed on the connecting sleeve; the pull rod is sleeved in the spring after passing through the forceps rod, the connecting sleeve and the connecting base sequentially and then is inserted in the movable handle; the spring is positioned between the connecting base and the movable handle; the two forceps clips are arranged on the forceps clip seat; the forceps clip seat is fixed on the forceps rod; the head parts of the forceps clips are provided with clamping teeth; the tail ends of the two forceps clips are respectively connected with one ends of the two connecting sheets; and the other ends of the two connecting sheets are fixed on the pull rod. The hard foreign body forceps have the advantages of reasonable structure design, small volume of the forceps rod, smooth entrance and exit in small organic tissues of the human body, convenient use, flexible movement and good clamping effect.

Description

Rigid foreign body forceps

Technical field

This utility model relates to a kind of rigid foreign body forceps, and it mainly is that foreign body to people's internal lesions excision position carries out gripping, belongs to the medical device technology mechanical field.

Background technology

In tiny organ-tissue in human body (as urethra, bladder, nasal cavity, the ear etc.) operation process, because intracorporeal organ is little, lesion resection is littler, and the foreign body at lesion resection position needs special-purpose foreign body gripping apparatus to take out in human body.When prior art is carried out gripping to the foreign body at the tiny organ-tissue lesion resection of human body position, there is not special-purpose gripping apparatus, can only carry out gripping with general tiny type section pincers, its defective is: operation is used and is not matched, be not the specialty the gripping instrumentation not smoothly, and the 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 foreign body forceps that can be effectively the foreign body at people's internal lesions excision position be carried out gripping.

This utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of rigid foreign body 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 and brace; Described fixed handle and flexible handle are interconnection, and 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 and fixing; Pull bar is inserted in spring after passing claw beam, adapter sleeve and Connection Block successively, penetrates in the flexible handle, and fixes with fixed screw; 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 latch, and two latches match each other; 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 1.6 millimeters.

This utility model compared with prior art has following positive effect: reasonable in design, and the claw beam volume is little, and is smooth in the tiny organ-tissue turnover of human body; Easy to use, flexibly movable, gripping is effective.

Description of drawings

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

Fig. 2 is the structural representation of latch 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 fixed screws, 12 screws; 13 fixed handles, 14 flexible handles, 15 brace steady pins, 16 link pins, 17 latches.

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 and brace 3.Wherein fixed handle 13 is connected by screw 12 with flexible handle 14, and 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, penetrates again in the flexible handle 14, and fixing with fixed screw 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 17, two latches of latch 17 clamp and matches each other; 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 1.6 millimeters, and when the foreign body to people's internal lesions excision position carried out gripping, claw beam 5 was smooth in the tiny organ-tissue 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, the foreign body at 1 pair of lesion resection position of two clamps carries out gripping.Under the visual field of endoscope, 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.
