Abstract
The invention provides a string suture machine, which comprises an upper clamping seat and a lower clamping seat, wherein the upper clamping seat and the lower clamping seat are mutually hinged into a shear shape, the front ends of the upper clamping seat and the lower clamping seat are respectively provided with a nail bin assembly, the back ends of the upper clamping seat and the lower clamping seat are provided with a safety rod, one end of the safety rod is pivoted on the upper clamping seat, the two side surfaces of the other end of the safety rod are convexly provided with two opposite convex strips along an axis of the safety rod, the two convex strips and the top ends of the end of the safety rod form an U-shaped groove, the distance between the two convex strips is equal to the thickness of the lower clamping seat, and at least one part of lower clamping seat is clamped in the U-shaped groove. The string suture machine has the beneficial effect that under the usual condition, the lower clamping seat is clamped in the U-shaped groove, so the upper clamping seat and the lower clamping seat cannot transversely swing, the staggering is further avoided, and the false triggering of the string suture machine is also avoided.
Description
Technical field
The present invention relates to a kind of surgical operation purse-string suture device, belong to medical instruments field.
Background technology
Purse-string device for surgical department is a kind of medical apparatus and instruments that often uses when the physiological tissues such as intestinal are carried out surgical operation, and the quality of this instrument performance directly affects the operation process, plays very important effect for surgical effect.In prior art, all to do purse string suture at the organ stump when using Binding Instrument to carry out suture operation, so that then firmly ligation after inserting center-pole could implement the bookbinding operation.The method of implementing the purse string suture operation has two kinds: a kind of is manual suture, and not only operation is very wasted time and energy, and inserting needle has and deeply have shallowly, and needle gage is also inconsistent; Another kind is to use the purse string suture pincers, passes together the organized jaw of folder with the pin band wire and carries out purse string suture, and shortcoming is to pass with pin an aperture of jaw, inconvenient operation.
The automatic purse-string suture device that arises at the historic moment, the problems referred to above have been solved largely, Chinese patent ZL200510123051.4 has put down in writing a kind of automatic purse-string suture device, as shown in Figure 1, it is comprised of with nail bin groupware 3 upper holder 1, lower holder 2, two holders intersect and pass through pivot structure 5 composition scissor-shaped structures, and nail, pushing slice of nail and purse wire are arranged in nail bin groupware 3.After clamping two of up and down holder 1,2, the nail in nail bin is just pulled the trigger out, purse wire is fixed on organizes outer wall, then just can tighten up purse wire and prick pocket.
In order to prevent upper holder 1, lower holder 2 maloperation in transportation or other situations, generally can shown on the handle end pivot of holder 1 bumper bar 4 is set, the end face of this bumper bar 4 withstands lower holder 2, go up like this holder 1, lower holder 2 in the situation that unnecessary just can not be mutually closed.But because bumper bar 4 is distant from pivot structure 5, so in reality, bumper bar 4 can produce certain twisting.Ultimate attainment situation as shown in Figure 2, the end face of described bumper bar 4 breaks away from lower holder 2 fully, only the side of bumper bar 4 is resisted against on lower holder 2.In this situation, the clamping that two holders 1 in up and down, 2 can be random or unclamp in case up and down holder 1,2 clamps, can cause the nail bin groupware mistakenly hit to be sent out.
The present invention quotes the content that this patent is put down in writing as prior art.
Summary of the invention
The object of the invention is to solve above-mentioned technical problem, a kind of purse-string suture device simple and reliable for structure is provided.
Purpose of the present invention is achieved through the following technical solutions:
A kind of purse-string suture device, comprise: be hinged into scissors-like upper and lower holder, the front end of described upper and lower holder is provided with nail bin groupware, the rear end is provided with bumper bar, one end pivoting of described bumper bar is located on holder, convex with two relative raised lines along its axis on the two sides of the other end of described bumper bar, the end face of described two raised lines and this end forms U-lag, distance between described two raised lines equals the thickness of lower holder, uses so that at least part of lower holder is stuck in described U-lag.
Beneficial effect of the present invention is mainly reflected in: generally, lower holder is stuck in U-lag, makes the up and down holder can not left and right twisting, and then avoids the generation that misplaces, also sends out with regard to the mistakenly hit of having avoided purse-string suture device.
Description of drawings
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Fig. 1: the schematic perspective view of prior art purse-string suture device.
Fig. 2: prior art purse-string suture device mistakenly hit is sent out the schematic diagram under state.
Fig. 3: the schematic diagram of the bumper bar of purse-string suture device of the present invention.
Fig. 4: the partial schematic diagram of purse-string suture device of the present invention.
The specific embodiment
the present invention has disclosed a kind of purse-string suture device, in conjunction with Fig. 3 and shown in Figure 4, the same with prior art, comprise equally hinged upper of similar shears, lower two handles holders 1, 2, on described, lower holder 1, 2 front end is provided with nail bin groupware 3, the rear end is provided with bumper bar 4, one end of described bumper bar 4 is located on upper holder 1 by hinge portion 43 pivots, convex with two relative raised lines 42 along its axis on the two sides of the other end of described bumper bar, described two raised lines 42 form U-lag with the end face 41 of this end, distance between described two raised lines 42 equals the thickness of lower holder 2, with so that at least part of lower holder 2 be stuck in described U-lag.Upper and lower holder 1,2 can not be twisted the left and right, and then avoid the generations of upper and lower holder 1,2 dislocation, also send out with regard to the mistakenly hit of having avoided purse-string suture device.
The present invention is simple in structure, is fit to promote.
All employings are equal to replacement or equivalent transformation and all technical schemes of forming, within all dropping on the scope of protection of present invention.
