It selects a good opportunity meeting.Compared to traditional open operation, laparoscopic surgery, which avoids long notch, facilitates the rehabilitation of patient.In addition, abdominal cavity
In videoendoscopic surgery, lens of laparoscope can provide openr, the clearer visual field for doctor, be conducive to doctor and more favorably accomplish
Operation reduces operation risk.Therefore, laparoscopic surgery is very universal at present as a kind of Minimally Invasive Surgery mode.
In laparoscopic surgery, since in-vivo tissue is easy to block lens of laparoscope, to influence the visual field, and then hand is influenced
Art, it is thus typically necessary to strutted the tissue for blocking lens of laparoscope using spreading mechanism in laparoscopic surgery, also,
It needs that film is delivered to intracavitary rear expansion using spreading mechanism, then by film adhered to the position for needing film.It is currently used for
In spreading mechanism in laparoscopic surgery often only there are two can open, collapses strut part, in this way, strut part opening when,
Group is woven in be softened on (left and right) direction up and down, and is not softened in the tissue controlled on (upper and lower) direction, therefore will be after
Continuous to block lens of laparoscope, the effect for strutting tissue is poor.In addition, intracavitary, film struts the strutting under effect of part at two
And be unfolded, but film is only by the power of both direction, therefore it is smaller to be unfolded rear film area, be difficult to be completely covered sometimes need it is thin
The position of film, the effect for strutting film are poor.
Summary of the invention
The invention is intended to provide a kind of laparoscopic surgery distraction instrument, to solve existing laparoscopic surgery support booting
The problem for strutting effect difference of structure.
In order to achieve the above object, base case of the invention are as follows: laparoscopic surgery distraction instrument, including operation bar,
First spring and second spring offer cavity in the operation bar, slide plate are slidably connected in cavity, is fixedly connected in cavity
There is fixed plate, slide plate is connect with fixed plate by the first spring；The slide plate is equipped with several strut far from the side of fixed plate
Group, each strutting group includes two mounting bases being oppositely arranged, and is hinged with strut in each mounting base, and two struts pass through the
The connection of two springs, slide plate are fixedly connected with connecting rod close to the side of fixed plate, and connecting rod runs through fixed plate, connecting rod far from slide plate one
End is fixedly connected with drawstring.
The working principle and beneficial effect of this base case is:
1, drawstring is pulled to apply pulling force to connecting rod, so that slide plate is slided to fixed plate direction, the support being hinged in mounting base
Bar is mobile to fixed plate direction, and under the limitation of operation boom end, strut is collapsed, and the increase of the sliding distance with slide plate,
Strut can be contracted to completely in the cavity of operation bar；And when discharging drawstring, slide plate is under the action of the first spring to far from solid
The direction of fixed board is slided, and strut is mobile to the direction far from fixed plate, and strut gradually struts under the action of second spring, is realized
Strut strutting and collapsing.Have in this base case it is several strut group, therefore, the quantity of strut is more and is even number, can
Intraluminal tissue is strutted from multiple directions, avoids tissue from blocking lens of laparoscope, and film can also be strutted from multiple directions, makes
It obtains film to be unfolded along multiple directions, the film size after expansion is larger, and the position for needing film can be completely covered, strut effect
It is good.
2, can be by controlling the moving distance of drawstring, thus the position of adjusting slider in this base case, and then it can
The distraction angle of strut is adjusted, struts area with what this controlled more struts.
3, in this base case, more collapse after strut can be completely into the cavity of operation bar, therefore, when storage
The space occupied is few, and storage is convenient.
Further, the operation bar is equipped with hand-held part far from one end of strut, is hinged with hand-held pole on hand-held part, holds
Torsional spring is fixedly connected in portion, the other end of torsional spring is fixedly connected on hand-held pole；Channel is offered inside the hand-held part, is led to
Road is connected to cavity, and the drawstring passes through channel far from one end of connecting rod and is fixedly connected with hand-held pole.
Drawstring is fixedly connected far from one end of connecting rod with hand-held pole, at this point, the original state of the first spring is compressive state,
Strut collapses in the cavity of operation bar.When strut being needed to strut, need to only it apply active force to hand-held pole, so that hand-held pole is to hand
The rotation of portion direction is held, drawstring reduces the pulling force moment that connecting rod applies, and slide plate is under the action of the first spring to far from fixed plate
Direction sliding, strut gradually stretches out cavity, and strut gradually struts under the action of second spring, and distraction angle is by holding
The angle that bar is rotated to hand-held part direction determines, i.e., is determined by user.When strut being needed to collapse, hand-held pole, hand-held pole are decontroled
It rotates and resets under the action of torsional spring, drawstring is pulled to reset, so that strut is collapsed into cavity, it is easy to operate.And this programme
In, since the normality of strut collapses in cavity, the occupied parking space of distraction instrument in this programme is small,
And storage can be stacked, is independent of each other.
Further, the slide plate and fixed plate form seal chamber in cavity, it is described strut group and further include two opposite set
The cylinder body set slidably connects piston in cylinder body, and cylinder body is divided into upper chamber and lower chambers by piston, and piston is fixedly connected with work
Stopper rod, piston rod are equipped with lantern ring far from one end of piston, and strut is located in lantern ring；The slide plate offers air flue, and air flue connects
Logical upper chamber and seal chamber.
Since upper chamber is connected to seal chamber, when slide plate is slided to fixed plate direction, the volume of seal chamber subtracts
Small, internal pressure increases, and gas enters in upper chamber through air flue, and the internal pressure of upper chamber increases, and piston is slided to lower chambers direction, fixed
The piston rod being connected on piston applies active force to strut by lantern ring, so that the opposite fortune of two struts generation that position is opposite
It is dynamic, in this way, not only increase the gathering degree of strut compared to base case, also reduce rubbing for strut and operation boom end
The time is wiped, to reduce the abrasion of the two.
Further, venthole is offered on the lower chambers side wall opposite with piston.
Since the inside of lower chambers communicates with the outside world, the resistance to sliding of piston is reduced.
Further, the mounting base is fixedly mounted on the centre of slide plate.
Mounting base is mounted on the centre of slide plate, compared to the edge or other portions that mounting base is mounted on slide plate
For position, mounting means as the former, under the identical distance of slide plate slides, the angle that strut is strutted or collapsed is bigger.
Further, the strut offers annular groove far from one end of mounting base.
When strutting film, annular groove is capable of fixing film, and film is avoided to take off before fitting in the intracavitary position for needing film
From strut, pad pasting is caused to fail.
