Abstract
The invention discloses a kind of bull drag hook throid retractors, belong to thyroid gland area of medical devices, solve existing drag hook and use human body more, the bad problem of using effect, pass through and multiple drag hooks realizations opened on arms and opening arm are arranged.
Description
Technical field
The present invention relates to thyroid gland medical instruments fields.
Background technique
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 of the mankind is similar to butterfly, like shield first, therefore is named with this.Thyroid gland control uses energy
The speed of amount, adjusts body to other hormonal sensibility at manufacture protein.
And throid retractor is also known as goitre retractor, and operating field necessary instrument is appeared when being thyroid surgery,
The goitre retractor in operation is usually single head construction, i.e. only one retractor head, medical care when operation at present
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 is needed multiple personnel to come while being operated, occupied space,
Do not utilize the progress of operation.
Application No. is 2013104979416, the Chinese invention patent of entitled Double-head thyroid drag hook discloses a kind of double
Head goitre retractor, including handle, connecting rod and retractor head, the retractor head of the patent disclosure two heads first are usually to be distributed
, multiple retractor heads need preferably expose surgical field of view, and distance and position angle towards multiple directions drawing during surgery
Deng can not all adjust, using effect is limited.
Summary of the invention
It is an object of the invention to: in view of the above problems, a kind of bull drag hook throid retractor is provided, wrapped
It includes:
Arm is opened, the opening arm quantity is two, and opening arm is arc, and each opening arm is equipped with drag hook, is opened
Arm includes the arm body connected with drag hook and the connecting rod hinged with adjusting rod, and connecting rod and arm body are hinged；
Drag hook, the drag hook include the first drag hook bar, the second drag hook bar, and the end of the first drag hook bar is equipped with hook
Portion and the connecting pin of the second drag hook bar are equipped with the recess portion being axially distributed, and the second drag hook bar is equipped with and the protrusion of recesses fit, protrusion
It is equipped with spring a, spring a is connected with protrusion and recess portion bottom respectively, and when protrusion is stuck in recess portion, spring a is equipped with one in advance
Tension is carried, the second drag hook bar, which passes through, opens arm, and the two sides that the second drag hook bar opens arm, which are equipped with, to be covered in the second drag hook bar
On spring b and nut, by the detent block detent that is located on the second drag hook bar, spring b is located at detent block and opens arm spring b
Between, nut and the second drag hook bar are threadedly coupled；
Outer tube, the outer tube include outer tube head, bar portion and nut portions, and bar portion is opened between outer tube head and nut portions
Open arms is hinged on outer tube head, and nut portions inner wall is equipped with screw thread；
Adjusting rod, adjusting rod includes the first adjusting rod, the second adjusting rod for connecting with the first adjusting rod, the second adjusting rod phase
Radial to can be rotated to the first adjusting rod axial restraint, the second adjusting rod is equipped with screw thread and is threadedly coupled with nut portions.
It is hinged and different with traditional mode on the outer arm disclosed by the invention for opening arm and adjusting rod and outer tube,
Two drag hooks are set to and are opened on arm, adjusting rod, which is moved forward and backward to adjust, opens the angle that arm opens, and then adjusts and draw
The lead of hook, a hand can adjust 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 cooperate 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
Whole, the present invention is equipped with spring b and is limited by way of nut, when in use, is fixed drag hook with hand, is adjusted
Nut is saved until length is applicable in.But had a problem that with nut adjustment, be exactly end hook portion tractive force be difficult by
The tactile of manpower senses, so drag hook is equipped with two sections by the present invention, and by a spring connection, two sections can be by recessed
Portion and protrusion are blocked, and when blocking, spring, which is located at, pulls open state, (are less than spring when the power for drawing tissue is lesser
Preload force), two sections of drag hook do not have to separation, and drag hook is in the state of rigidity, (are greater than when the power for drawing tissue is larger
Spring preload power), two sections of drag hook have it is certain move to axial, drag hook is in a kind of state of elasticity, can reduce
Hook portion draws the transition of tissue, injures tissue.
As an improvement, the end of second adjusting rod is equipped with the handler of the second adjusting rod of rotation, 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 use of the first adjusting rod can lead to the two diameter using existing
To rotation, the connection type of axial restraint is such as connected in such a way that ball connects, and the second adjusting rod is equipped with spherojoint, Huo Zhe
Two adjusting rods are stuck in the first adjusting rod for cylindrical body, and can preferably be rotated in such a way that ball connects, use when
It waits, the tractive force of tissue is generally possible to guarantee that the second adjusting rod is rotated relative to the first adjusting rod.
As an improvement, the area of the section circle of outer tube head is greater than the area of bar portion section circle, outer tube head inner wall is equipped with and is used for
The movable chamber of connecting rod opens arm and is hinged on the outer layer arm of outer tube head, and the area for reducing bar portion can preferably save sky
Between, middle external tube head, bar portion and nut portions can also use the side of integrated molding by the way of being fixedly connected
Formula, wherein adjusting rod passes through bar portion and nut portions, and end is located in the chamber of outer tube head, and carries out hingedly with connecting rod.
Second drag hook bar and opening arm need fixed radial direction when in use, can be fixed using manpower, can also
To improve fixation to structure, in a preferred embodiment, the outside of the second drag hook bar, which is equipped with, to be axially distributed
Raised line, the inner wall for opening arm is equipped with and the groove of recessed bar cooperation, the cooperation of raised line and groove so that the second drag hook bar and
Open arms is axially moveable, radially fixed.And rotating nut is only needed in this way, the length of drag hook can be adjusted automatically
Section.
In the present invention, longer opening arm can be set, and 1 or multiple drawings can be set on each opening arm
Hook, such as 2 or 3, adjust 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 better co-ordination, the drag hook having in existing exerts oneself
Greatly, some is firmly small, and opening is caused to be easily deformed.
