Abstract

The utility model discloses a kind of U-shaped folding broken screw tail end fracturer, including thick handle, thin handle, spring, bolt axle, the U-shaped head that fractures, first fracture head, second fracture head, neck, pressurization card article and screw tail end, spring is provided between thick handle and the upper end of thin handle, the lower end of thick handle and thin handle is provided with the U-shaped head that fractures, pressurization card article is provided with neck, the beneficial effect that the utility model is reached is：By installing little spring, pressurization card article is automatically springed open, the rear nut tail end can that fractures easily is deviate from automatically, is not in stuck phenomenon, so reaches time saving purpose, saves operating time；It is laborsaving, it is easy to operator to operate, improves surgical quality, improves operator and operate comfort；The utility model small volume, particularly distal end is enclosing square shape, occurs without soft tissue insertion, neck is more micro- than screw tail end greatly a bit, can be easily inserted screw tail end, it is not necessary to expose surgical field of view too much, reduce surgical exposure damage.

Description

A kind of U-shaped folding broken screw tail end fracturer

Technical field

A kind of U-shaped folding broken screw tail end fracturer is the utility model is related to, belongs to technical field of medical instruments.

Background technology

Vertebral fixity system has been widely used for the clinical treatment of spinal surgery at present.With its application increasingly Extensively, pedicle screw is broken into the problem of clinician will often face, and it can cause Unstable internal fixation, bone fusion rate drop It is low, pseudarthrosis formation the problems such as, currently there are fracturer, including simple neck shape：Need it is secondary taken out out of neck, Cause inconvenience waste operating time of performing the operation；Clamp shape：Handle is short, and arduously, head end is larger, is not easy to operate.Therefore, more particularly to one Kind U-shaped folding broken screw tail end fracturer, avoid screw from fractureing stuck phenomenon, facilitate operation to be easily inserted screw tail end, no Need to expose surgical field of view too much, reduce surgical exposure damage.

Utility model content

The utility model provides a kind of U-shaped folding broken screw tail end fracturer simple in construction, easy to use, effectively solves The problem of existing pedicle screw tail end fracturer inconvenience operation technique.

In order to solve the above-mentioned technical problem, the utility model provides following technical scheme：

A kind of U-shaped folding broken screw tail end fracturer of the utility model, including thick handle, thin handle, spring, bolt axle, U Type fracture head, first fracture head, second fracture head, neck, pressurization card article and screw tail end, the thick handle and thin handle it is upper The spring is provided between end, and one end of the spring is fixedly connected with the thick handle, the thick handle and the thin hand The lower end of handle is provided with the U-shaped head that fractures, and the U-shaped head that fractures fractures head including described first head and described second that fractures, and Described first head and described second that fractures fractures and is flexibly connected by the bolt axle between head, and described first fractures the outer of head Side is provided with the neck, and the middle part of the neck is provided with the pressurization card article.

As a kind of optimal technical scheme of the present utility model, the thick handle and the thin handle use long handle.

As a kind of optimal technical scheme of the present utility model, there is the spiral shell side of the pressurization card article by neck card Follow closely tail end.

As a kind of optimal technical scheme of the present utility model, the width of the neck is more than the diameter of screw tail end.

The beneficial effect that the utility model is reached is：The utility model automatically springs open pressurization card by installing little spring Bar, the rear nut tail end can that fractures easily are deviate from automatically, are not in stuck phenomenon, it is not necessary to which secondary clamp takes out, so Reach time saving purpose, save operating time；Thick handle and thin handle are designed using long handle, use more laborsaving, are easy to hand Patient operates, and improves surgical quality, improves operator and operates comfort.In addition, the utility model small volume, is particularly distally Enclosing square shape, soft tissue insertion is occurred without, neck is more micro- than screw tail end greatly a bit, can be easily inserted screw tail end, it is not necessary to Too many exposure surgical field of view, reduces surgical exposure damage.

Embodiment

In order that the purpose of this utility model, technical scheme and advantage are clearer, it is right with reference to the accompanying drawings and examples The utility model is described in further detail.

Embodiment of the present utility model：As shown in figures 1-4, U-shaped folding broken screw tail end fracturer of the present utility model, Including thick handle 1, thin handle 2, spring 3, bolt axle 4, it is U-shaped fracture first 5, first fracture first 6, second fracture first 7, neck 8, plus Card article 9 and screw tail end 10 are pressed, spring 3, and one end of spring 3 and thick handle are provided between thick handle 1 and the upper end of thin handle 2 1 is fixedly connected, the lower end of thick handle 1 and thin handle 2 be provided with it is U-shaped fracture first 5, U-shaped fracture first 5 fractures first 6 and the including first Eighty percent discount broken end 7, and first fractures and first 6 and second fracture and be flexibly connected by bolt axle 4 between first 7, and first fracture first 6 it is outer Side is provided with neck 8, and the middle part of neck 8 is provided with pressurization card article 9.

Thick handle 1 and thin handle 2 use long handle, are advantageous to laborsaving, are easy to operator to operate, raising surgical quality, carry High operator operates comfort.

There is screw tail end 10 side of pressurization card article 9 by the card of neck 8, avoids coming off for screw tail end 10.

The width of neck 8 is more than the diameter of screw tail end 10, can be easily inserted screw tail end 10, it is not necessary to exposes hand too much The art visual field, reduce surgical exposure damage.

Specifically, the utility model in use, designed using distal end neck 8, is just facilitated screw tail end 10 to insert, passed through Lever principle presses screw tail end 10 in one pressurization card article 9 of side central design of neck 10, in pressurization card article 9 distal end is convex to Side, will not voluntarily it be slid in screw tail end 10 after taking-up fractures.When hand unclamps, lead between the thick handle 1 of hand and thin handle 2 Spring 10 is crossed, automatically springs open pressurization distal end card article, the can of rear nut tail end 10 that fractures easily is deviate from automatically, is not in block Phenomenon, it is not necessary to which secondary clamp takes out, and so reaches time saving purpose, saves operating time.
