Description
Technical field
The utility model relates to a kind of three leaf of doublejointed pincers for small notch suture, belong to the field of medical instrument technology.
Background technique
With the continuous development of medical level, single-hole laparoscopic and single hole thoracoscopic operation due to notch compared with small, bleeding is few,
It is wider to restore fast clinically application range.Hysteroscope and other surgical instruments pass through small notch and enter chamber in the course of surgery
It is interior, it had not only needed not influence each other in parallel between each instrument but also each instrument is needed to work normally in the smallest angular range as far as possible, because
This, conventional surgical instrument is not able to satisfy the needs of single hole endoscope-assistant surgery, uses with more inconvenience.
Summary of the invention
Purpose of the utility model is to solve surgical instrument existing in small incision surgery problems inconvenient for use, mention
Supply a kind of structure simple, three leaf of the doublejointed pincers for small notch suture compact to design.
The utility model adopts the following technical solution: a kind of three leaf of doublejointed pincers for small notch suture, including jaw,
The junction of slide bar and handle, the jaw and slide bar is the first joint, and the junction of the handle and slide bar is second joint,
The jaw is bent upwards to form arc, and the jaw includes the first caliper, the second caliper and fixed caliper, and the handle includes
First, which refers to that circle, second refer to circle and fix, refers to circle, and the slide bar includes intermediate fixed link and is respectively arranged at fixed link upper end
With the upper slide bar and drop shot of lower end, the upper slide bar and drop shot can be slided along fixed link level respectively, the upper slide bar
Front end be connected with the first caliper, the rear end of the upper slide bar refers to that circle is connected with first, the front end of the drop shot and the
Two calipers are connected, and the rear end of the drop shot refers to that circle is connected with second, and the front end of the fixed link is connected with fixed caliper
It connects, the rear end of the fixed link refers to that circle is connected with fixation.
Further, the fixation refers to that the two sides of circle are respectively arranged with the first lock and the second lock.
Further, first caliper, the second caliper are 15-45 ° relative to the angle that fixed caliper opens.
Further, the bending angle of the jaw is 20-60 °.
Further, shaggy tooth is provided on the jaw.
The utility model structure is simple, compact to design, easy to use, is particularly suitable for the suture of small incision surgery, can
It clamps structural two operative sites simultaneously while being sutured, shorten operating time, reduce bleeding risk, arc vice jaw
Surgical field of view sufficiently exposure can be made not influence hysteroscope and the normal use of other surgical instruments, upper slide bar and drop shot band respectively
It moves corresponding caliper to open or be closed, the activity point of view for reducing instrument makes it that can smoothly complete suture within the scope of small notch
Operation.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the left view of the utility model.
Appended drawing reference: jaw 1, the second caliper 1-2, fixed caliper 1-3, slide bar 2, upper slide bar 2-1, is consolidated first caliper 1-1
Fixed pole 2-2, drop shot 2-3, the finger of handle 3, first enclose 3-1, the second finger circle 3-2, fixed refer to and enclose 3-3, the first joint 4, second pass
Section the 6, second lock 7 of the 5, first lock.
Specific embodiment
Below in conjunction with attached drawing, the utility model will be further described.
As Figure 1-Figure 2, a kind of three leaf of doublejointed pincers for small notch suture, including jaw 1, slide bar 2 and handle
3, the junction of jaw 1 and slide bar 2 is the first joint 4, and the junction of handle 3 and slide bar 2 is second joint 5, and jaw 1 is bent up
Curved camber, jaw 1 include the first caliper 1-1, the second caliper 1-2 and fixed caliper 1-3, and handle 3 includes that the first finger encloses 3-
1, second refers to that circle 3-2 and fixed refer to enclose 3-3, and slide bar 2 includes intermediate fixed link 2-2 and is respectively arranged on fixed link 2-2
The upper slide bar 2-1 and drop shot 2-3 at end and lower end, upper slide bar 2-1 and drop shot 2-3 can be sliding along fixed link 2-2 level respectively
Dynamic, the front end of upper slide bar 2-1 is connected with the first caliper 1-1, and the rear end of upper slide bar 2-1 refers to that circle 3-1 is connected with first, glides
The front end of bar 2-3 is connected with the second caliper 1-2, and the rear end of drop shot 2-3 refers to that circle 3-2 is connected with second, fixed link 2-2's
Front end is connected with fixed caliper 1-3, and the rear end of fixed link 2-2 refers to that circle 3-3 is connected with fixed, the fixed two sides for referring to circle 3-3
It is respectively arranged with the first lock 6 and the second lock 7, the first caliper 1-1, the second caliper 1-2 are opened relative to fixed caliper 1-3
Angle is 15-45 °, is provided with shaggy tooth on jaw 1, can increase friction in clamping process.
During single hole endoscope-assistant surgery, when needing to carry out tissue suture, by the jaw 1 of three leaf of doublejointed pincers and part
Slide bar 2 stretches in small notch.The first finger circle 3-1, the second finger circle 3-2 and fixed refer to, which are fixed, with finger respectively encloses 3-3, it is fixed
Refer to that circle 3-3 is motionless, opens first and refer to that circle 3-1 and second refers to circle 3-2, first refers to that circle 3-1 drives upper slide bar 2-1 sliding along fixed link
It is dynamic, to drive the first caliper 1-1 relative to the opening and closing of fixed caliper 1-3 progress certain angle, while second refers to circle
3-2 drives drop shot 2-3 to slide along fixed link 2-2, so that it is certain to drive the second caliper 1-2 to carry out relative to fixed caliper 1-3
The fixed of jaw 1 that the opening and closing of angle, the first lock 6 and the second lock 7 can be used in certain angle is kept, the first pincers
Body 1-1 and the second caliper 1-2 can be clamped simultaneously, therefore can carry out the suture of two operative segments simultaneously.Doublejointed
The design of slide bar significantly acts very much the clamping that jaw multi-angle can be realized so that being not necessarily to progress at handle, easy to use,
And do not influence the use of other instruments at small notch.
