Abstract
The utility model relates to a novel needle holder, in particular to a pair of micro needle holder scissors which belong to the technical field of medical appliances. The micro needle holder scissors consist of a needle holder, an elastic jointed body and a pair of micro scissors, wherein, the elastic jointed body is composed of two elastic pieces and a spring which is arranged between the two elastic pieces, the end part of a handle of the needle holder is connected with the end parts of the handles of the micro scissors by the elastic pieces, and the needle holder and the micro scissors are positioned at the two ends of the elastic jointed body. The utility model can reduce the unnecessary operations effectively during the operation, shorten the operation time and eliminate the inharmonic matching actions between the operators and the assistants, more particularly facilitate to finish the operation for the operators singly.
Description
One, technical field
This utility model relates to a kind of novel needle holder, and particularly a kind of micro-needle holder is cut, and belongs to technical field of medical instruments.
Two, background technology
Micro-needle holder, microscissors are eye microsurgery operating apparatuss commonly used, as publication number is the Chinese patent of CN2155835, the needle holder that angle is arranged between the axis of a kind of sharp mouth and Handheld Division is disclosed, this needle holder folder pin is stable, easy to operate, can shorten operating time, reduce labor intensity, improve the success rate of operation, but when using this needle holder and traditional like instrument, also need the assistant to hold microscissors and cooperate, therefore need constantly be used alternatingly above-mentioned two kinds of apparatuses, the waste operating time.
Three, summary of the invention
At the deficiencies in the prior art, the invention provides a kind of micro-needle holder cuts, purpose is that needle holder and microscissors are organically combined, outside the function that keeps original each apparatus, reduce the unnecessary operations in the operation, shorten operating time, eliminated between operator and the assistant and cooperates not tacit action, especially to operator finish separately perform the operation favourable.
A kind of micro-needle holder is cut, by needle holder, elasticity is conjuncted and microscissors is formed, described elasticity is conjuncted to be made of two shell fragments and spring, spring is arranged between two shell fragments, the handle end of needle holder is connected by shell fragment with the microscissors handle end, and needle holder and microscissors are positioned at the conjuncted two ends of elasticity.The conjuncted main effect of this elasticity provides elastic force, makes two pages of needle holder and microscissors to be in open configuration.
Described spring is fixed in the shell fragment middle part.
The maximum compression length of described spring is less than or equal to the spacing of needle holder and microscissors closure state handle.
Described needle holder point mouth axis and needle holder handle axis have 15 ° of-25 ° of angles.
Described microscissors point mouth axis and microscissors handle axis have 15 ° of-25 ° of angles.
When using this utility model, can freely select to use the position, reach the purpose of control needle holder and microscissors then by handle opening and closing degree by conjuncted control needle holder of compression elasticity and microscissors.
This utility model beneficial effect is as follows:
1, by combining needle holder and microscissors are organic, the person that makes the operation technique uses difunctional micro-needle holder to cut just can to finish over and needs above-mentioned two kinds of steps that apparatus just can be finished, eliminate the trouble of two kinds of apparatuses of continuous replacing, effectively shortened operating time.
2, operator can use needle holder and microscissors according to the needs of oneself, has overcome between operator and the assistant to cooperate the not tacit shortcoming that causes operating time to prolong.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model.
Wherein: 1, needle holder, 2, elasticity is conjuncted, 3, microscissors, 4, shell fragment, 5, spring, 6, needle holder point mouth, 7, microscissors point mouth, 8, the needle holder handle, 9, the microscissors handle.
Five, the specific embodiment
Below in conjunction with accompanying drawing, further set forth this utility model
Embodiment
A kind of difunctional micro-needle holder is cut, and is made up of needle holder 1, elasticity conjuncted 2 and microscissors 3, and described elasticity is conjuncted to be made of shell fragment 4 and spring 5, and spring 5 is arranged between the shell fragment 4, and needle holder handle 8 ends are connected with microscissors handle 9 ends by shell fragment 4.Described elasticity conjuncted 2 is made of two shell fragments 4 and a spring 5.Described spring 5 is fixed in shell fragment 4 middle parts, the minimum compressed length of described spring 5 is less than or equal to the spacing of needle holder 1 and microscissors 3 closure state handles, and described needle holder is cut sharp mouth 6 and microscissors point mouth 7 axis and needle holder handle 8 and microscissors handle 9 axis one 20 ° of angles.
This utility model protection domain is not limited only to the foregoing description, and as by to spring, shell fragment quantity, the simple change of spring, shell fragment connected mode all falls into protection domain of the present utility model.
