Abstract

The utility model relates to a surgical instrument, in particular to a pair of chest-penetrating artery blocking forceps. The pair of chest-penetrating artery blocking forceps comprise a large fixed body and a large movable body, wherein the large fixed body is connected with a fixed forceps head; the large movable body is connected with a movable forceps head; the other ends of the large fixed body and the large movable body are respectively connected with finger ring type shanks; the chest-penetrating artery blocking forceps are characterized in that the large fixed body and the large movable body are bent by 20 degrees towards the same direction; the fixed forceps head and the movable forceps head are bent by 20 degrees again along the large fixed body and the large movable body; matched lock buckles are respectively arranged on the inner sides of the two finger ring type shanks; DeBakey teeth are respectively arranged on the inner sides of the fixed forceps head and the movable forceps head. By the use of the chest-penetrating artery blocking forceps, interference to operation in a surgical region can be avoided; the chest-penetrating artery blocking forceps are convenient to open and close, and free motion getting into and getting out of an operating hole is facilitated; influence caused by the thickness of the chest wall and the depth of a thoracic cavity are eliminated; injuries to surrounding tissues by the forceps are avoided, and the chest-penetrating artery blocking forceps adapt to the operating habit of a doctor and conform to the principle of the human engineering; sliding of blood vessels can be prevented favorably, and the clamping force is more flexibly adjusted.

Description

A kind of through thoracic aorta blocking-up pincers

(1) technical field

This utility model relates to a kind of operating theater instruments, particularly a kind of through thoracic aorta blocking-up pincers.

(2) background technology

At present, cardiac surgery operation dams to aorta enforcement blocking-up after mostly need setting up extracorporeal circulation, and the existing blocking-up that adopt clamp and are mostly simple joint blocking-up pincers more.But in Cardiac Surgery Minimally Invasive Surgery, operative space is narrow and small, common aortic occlusion clamp occupies surgical field of view, disturbs operation technique, is difficult for opening through breast operation, cannot meet the operation requirements of Cardiac Surgery Minimally Invasive Surgery.

(3) summary of the invention

This utility model is in order to make up the defect of prior art, provide one to meet ascending aorta blocking-up demand in Cardiac Surgery Minimally Invasive Surgery, the visual field of being convenient to perform the operation exposes and is easy and simple to handle, shorten as much as possible incision length, reduce operation wound, improve the safety of instrumentation and clamping through thoracic aorta blocking-up of efficiency.

This utility model is achieved by the following technical solution:

A kind of through thoracic aorta blocking-up pincers, comprise fixing bodice and movable bodice, fixing bodice is connected and fixed binding clip, movable bodice connection activity binding clip, described fixing bodice and the movable bodice other end are connected with respectively and refer to ring type handle, it is characterized in that, bending in the same way 15～25 ° of described fixing bodice and movable bodice, described fixed pliers head and movable binding clip are along bending 15～25 ° again, the direction of fixing bodice and movable bodice bending.

The angle of bend of described fixing bodice, movable bodice, movable binding clip and fixed pliers head is all 20 °.

Described two refer to that ring type handle inner side is respectively equipped with the snap close matching.

Described fixed pliers head and movable binding clip inner side are respectively equipped with De Bakey tooth.

The fixed pliers head at described fixing bodice and its two ends and refer to the movable bodice at ring type handle, movable bodice and its two ends and refer to that ring type handle passes through respectively pin hinged.

The beneficial effects of the utility model are:

Puncture and insert through intercostal space through thoracic aorta blocking-up pincers, avoid interference the operation in art district.Doublejointed design makes the convenient activity that opens and closes, passes in and out in handle hole freely of blocking-up pincers, is not subject to the impact of thoracic wall thickness, the thoracic cavity depth, avoids Crushing injury surrounding tissue.The camber design of caliper can just be blocked pliers grip and be attached at thoracic wall, meets the principle of doctor's operating habit and ergonomics.The tooth portion structure of binding clip is conducive to the slip of anti-hemostatic tube, and latch structure makes the adjustment of clamp power more flexible.Thereby, have good value for applications in Cardiac Surgery Minimally Invasive Surgery field.

(4) accompanying drawing explanation

Below in conjunction with accompanying drawing, this utility model is further described.

Fig. 1 is main TV structure schematic diagram of the present utility model;

Fig. 2 is the plan structure schematic diagram of this utility model open configuration.

In figure, 1 fixing bodice, 2 movable bodices, 3 fixed pliers heads, 4 movable binding clips, 5 finger ring type handles, 6 snap closes, 7 De Bakey teeth, 8 anti-slip veins, 9 pins.

(5) specific embodiment

Accompanying drawing is specific embodiment of the utility model.As Fig. 1, shown in Fig. 2, this kind is through thoracic aorta blocking-up pincers, comprise cross one another standing part and movable part, standing part comprises the fixed pliers head 3 that fixing bodice 1 is connected by pin 9 with its two ends and refers to ring type handle 5, movable part comprises the movable binding clip 4 that movable bodice 2 is connected by pin 9 with its two ends and refers to ring type handle 5, in the time referring to that ring type handle separates 5 for two, fixed pliers head 3 is motionless, only have movable binding clip 4 opened with certain angle, two inner sides that refer to ring type handle 5 are respectively equipped with the snap close 6 matching, it is a protruding block extending to the inside from referring to ring type handle 5, in the time referring to that ring type handle 5 closes for two, two snap close 6 staggered contacts up and down, there is anti-slip veins 8 two relative one sides of snap close 6, fixed pliers head 3 and movable binding clip 4 inner sides are respectively equipped with De Bakey tooth 7, can slide by anti-hemostatic tube like this, be conducive to fixed pliers head 3 and movable binding clip 4 is clamped blood vessel, bending 15～25 ° in the same way of fixing bodice 1 and movable bodices 2, preferably 20 °, that is to say that the angle that fixing bodice 1 and movable bodice 2 are bent to form is 160 °, fixed pliers head 3 and movable binding clip 4 are along bending 15～25 ° again, the direction of fixing bodice 1 and 2 bendings of movable bodice, also preferably 20 °, the angle that is to say fixing bodice 1 and fixed pliers head 3 is 160 degree, the angle of movable bodice 2 and movable binding clip 4 is also 160 °.Fixed pliers head 3 and movable binding clip 4 front ends can also be arranged to bending.

Except technical characterictic described in description, all the other technical characterictics are those skilled in the art's known technology.
