Abstract
The invention discloses a kind of bull drag hook throid retractor, belong to thyroid gland area of medical devices, solve the problem of existing drag hook is more using human body, and using effect is bad, by setting the drag hook on multiple opening arms and opening arm and then realization.
Description
Technical field
The present invention relates to thyroid gland medical instruments field.
Background technology
Thyroid gland is the very important body of gland of vertebrate, belongs to endocrine organ.In mammal, it is located at neck first
Below shape cartilage, tracheae both sides.The thyroid gland likeness in form butterfly of the mankind, just as shield first, therefore is named with this.Thyroid gland control uses energy
The speed of amount, protein, regulation body are manufactured to other hormonal sensitiveness.
Appear the necessary apparatus of operating field and throid retractor is also known as goitre retractor, when being thyroid surgery,
The goitre retractor in operation is typically that single head constructs at present, i.e. an only retractor head, medical care when operation
Personnel hold tissue, fixed surgical field of view position by drag hook, but in an operation, field of excursion to need multiple
Retractor head is held, and such sometimes one personnel both hands will be held, or needs multiple personnel to operate simultaneously, space-consuming,
Do not utilize the progress of operation.
Application No. 2013104979416, the Chinese invention patent of entitled Double-head thyroid drag hook disclose a kind of pair
Head goitre retractor, including handle, connecting rod and retractor head, two heads first of retractor head disclosed in the patent are usually to be distributed
, multiple retractor heads, which need to draw towards multiple directions, in operation could preferably expose surgical field of view, and distance and position angle
Deng can not all adjust, using effect is limited.
The content of the invention
It is an object of the invention to：For above-mentioned problem, there is provided a kind of bull drag hook throid retractor, bag
Include：
Arm is opened, described opening arm quantity is two, and opening arm is arc, and each arm that opens is provided with drag hook, opens arm bag
The arm body connected with drag hook and the connecting rod being hinged with adjusting rod are included, connecting rod and arm body are hinged；
Drag hook, described drag hook include the first drag hook bar, the second drag hook bar, and the end of the first described drag hook bar is provided with hook portion,
The recess being axially distributed is provided with the connection end of the second drag hook bar, the second drag hook bar is provided with and the convex portion of recesses fit, on convex portion
Provided with spring a, spring a connects with convex portion and recess bottom respectively, and when convex portion is stuck in recess, spring a is provided with one and preloaded
Tension force, through arm is opened, the both sides of the second drag hook bar opening arm are provided with to be enclosed on the second drag hook bar the second described drag hook bar
Spring b and nut, spring b by the screens block screens that is located on the second drag hook bar, spring b be located at screens block and open arm it
Between, nut and the threaded connection of the second drag hook bar；
Outer tube, described outer tube include outer tube head, bar portion and nut portions, and bar portion opens arm between outer tube head and nut portions
It is hinged on outer tube head, nut portions inwall is provided with screw thread；
Adjusting rod, adjusting rod include the first adjusting rod, the second adjusting rod for being connected with the first adjusting rod, and the second adjusting rod is with respect to the
One adjusting rod axial restraint, radially rotatable, the second adjusting rod is provided with screw thread and is threadedly coupled with nut portions.
It is hinged on opening arm and the outer arm of adjusting rod and outer tube disclosed by the invention, and it is different with traditional mode,
Two drag hooks are arranged at and opened on arm, adjusting rod moves forward and backward can regulation and opens the angle that arm opens, and then adjusts and draw
The lead of hook, a hand can adjusts two drag hooks drawn to different directions when in use, if opening arm
Direction cannot adjust, when in use due to needing the direction drawn and drag hook direction not consistent, therefore apply limited.
In order to coordinate this angle to be capable of the direction of freely regulated arm, the length of drag hook axially is also required to adjust when in use
It is whole, of the invention by way of nut and spacing provided with spring b progress, when in use, drag hook is fixed with hand, adjusted
Nut is saved until length is applicable.But have a problem that the tractive force for being exactly end hook portion is difficult quilt with nut regulation
The tactile of human hand senses, so drag hook is provided with two sections by the present invention, and is connected by a spring, two sections can be by recessed
Portion and convex portion are blocked, and when blocking, spring, which is located at, pulls open state, when the power for drawing tissue is less（Less than spring
Preload force）, two sections of drag hook are in rigid state without separation, drag hook, when the power for drawing tissue is larger（It is more than
Spring preload power）, two sections of drag hook have it is certain move to axial, drag hook is in a kind of elastic state, can reduce
Transition traction of the hook portion to tissue, injures tissue.
As an improvement, the end of the second described adjusting rod is provided with the handler for rotating the second adjusting rod, setting for disease is rotated
Meter can preferably rotate the second adjusting rod, and then adjust and open the angle that arm opens.
In specific scheme, the second adjusting rod and the first adjusting rod use can cause both footpaths using existing
To rotation, the connected mode of axial restraint, such as connected by the way of ball connects, the second adjusting rod is provided with spherojoint, Huo Zhe
Two adjusting rods are stuck in the first adjusting rod for cylinder, and can preferably be rotated by the way of ball connects, use when
Wait, the tractive force of tissue is generally possible to ensure that the second adjusting rod rotates relative to the first adjusting rod.
As an improvement, the area of the section circle of outer tube head is more than the area of bar portion section circle, outer tube head inwall, which is provided with, to be used for
The chamber of connecting rod activity, open arm and be hinged on the outer layer arm of outer tube head, sky can preferably be saved by reducing the area of bar portion
Between, its middle external tube head, bar portion and nut portions by the way of being fixedly connected, can also use the side of integrated molding
Formula, wherein adjusting rod pass through bar portion and nut portions, and end is located in the chamber of outer tube head, and is hinged with connecting rod.
Second drag hook bar and opening arm need fixed radial direction when in use, can be fixed using human hand, also may be used
To be improved fixation to structure, in a preferred embodiment, the outside of the second drag hook bar, which is provided with, to be axially distributed
Raised line, the inwall for opening arm is provided with and groove that recessed bar coordinates, the cooperation of raised line and groove cause the second drag hook bar and
Open arms is axially moveable, radially fixed.And rotating nut is only needed in this way, the length can of drag hook is adjusted automatically
Section.
In the present invention, longer opening arm can be set, and 1 or multiple drawings each can be set on opening arm
Hook, such as 2 or 3, are adjusted according to the direction of opening when in use, open the angle of arm, secondly adjust the length of drag hook
Degree, can greatly save manpower, and between multiple drag hooks also can more preferable co-ordination, the drag hook having in existing exerts oneself
Greatly, some is firmly small, causes opening to be easily deformed.
