Description

Surgical Purse Stapler

technical field

The utility model relates to a suturing device used in surgical operations, in particular to a purse suturing device for surgery, which belongs to the technical field of medical instruments.

Background technique

Surgical purse-string suturing device is a medical device often used in surgical operations on intestinal and other physiological tissues. The performance of the instrument directly affects the operation process and plays a very important role in the operation effect. In the prior art, when using a stapler for suturing, purse-string sutures must be performed on the stump of the organ, so that it can be firmly ligated after the central rod is inserted, and then the stapler can be implemented. There are two methods for performing purse-string suture surgery: one is manual suture, which is not only time-consuming and labor-intensive, but also the depth of the needle is different, and the stitch distance is inconsistent; the other is to use purse-string suture forceps to thread the needle with thread Purse string suture is carried out by clipping organized jaws, but the disadvantage is that a needle needs to pass through a small hole in the jaws, which is inconvenient to operate. The application of the automatic purse device solves the above problems, but in the process of use, it is found that the connection between the connecting rod and the clip seat of the existing automatic purse device is in the shape of a "D", and the doctor puts it in the clip seat. After the tissue, observe whether the tissue is properly placed, the line of sight is blocked by the connecting rod of the clip seat, and the connecting rod of the clip seat needs to be swung left and right to observe both sides of the clip seat, which is not conducive to the smooth implementation of the operation.

Contents of the invention

The object of the present invention is to provide a purse-string stapler for surgery in order to solve the above-mentioned problems in the prior art.

The purpose of the present invention is achieved through the following technical solutions:

Surgical purse string stapler, including pairs of upper and lower staple cartridges, upper and lower clamp seats, clamp seat connecting rods and handles. One body, wherein: the connecting rods of the clamping seats are respectively connected to the side ends of the upper and lower clamping seats, that is, the connecting rods of the clamping seats and the connecting rods of the clamping seats are arranged in an "L" shape, and the angle between the clamping seats and the connecting rods of the clamping seats is 90 degrees to 135 degrees. between degrees.

In the purse-string stapler for surgery, at least one hook is provided on each of the paired two clamp seat connecting rods, and the hooks are matched with each other.

Further, the above-mentioned purse-string stapler for surgery, wherein: the two clip holder connecting rods, at least one of the clip holder connecting rods is provided with a safety bar.

Further, in the purse-string stapler for surgery, wherein: the side ends of the two clamp seats are provided with limiting devices.

Still further, in the above purse string stapler for surgery, wherein: the limiting device is a limiting rod arranged at one end of the connecting rod close to the clamp seat.

The outstanding substantive features and remarkable progress of the technical solution of the present invention are mainly reflected in:

Because the clip seat and the clip seat connecting rod of the purse string suture device for surgery are arranged in an "L" shape, the doctor who performs the operation can observe the clip seat intuitively. That is to say, the doctor can directly observe the placement of the tissue on the clip holder directly from the side of the clip holder connecting rod, and the line of sight is not blocked by the clip holder connecting rod. Whether the left and right sides are clamped properly reduces the difficulty for doctors to perform surgery, is easier to use, and has better results, and has a good prospect for popularization and application.

Detailed ways

The purse string stapler for surgery as shown in Figure 1 includes a pair of upper and lower staple bins, upper and lower clip seats 1, clip seat connecting rods 2 and handles 3, the upper and lower staple bins are respectively placed in the corresponding upper and lower clip seats 1, and the clip The base 1, the connecting rod 2 of the clamping base and the handle 3 are injection molded into one body, wherein: the connecting rods of the clamping base are respectively connected to the side ends of the upper and lower clamping bases, that is, the clamping base and the connecting rods of the clamping base are arranged in an "L" shape, and the clamping base and the clamping base are arranged in an "L" shape. The included angle between the seat connecting rods is between 90 degrees and 135 degrees. In order to keep the connecting rods 2 of the clamping seats in a relatively fixed state after clamping the human tissue, at least one hook 4a, 4b is respectively provided on the two connecting rods 2 of the clamping seats, between the hooks 4a, 4b paired with each other. At the same time, at least one clamp seat connecting rod 2 is provided with a safety lever 5 . The side ends of the two clip seats 1 are provided with limit rods as a stop device, which can ensure that the maximum opening state of the upper and lower clip seats 1 is constrained, and avoid false collisions to surrounding tissues.

The specific usage method and effect of the purse-string suturing device for surgery are as follows: firstly, the upper and lower clip seats 1 are superimposed, and the two are connected together by pins. Then safety bar 5 is installed on one side of clamp seat connecting rod 2 and it is opened, then upper and lower clamp base 1 is connected with stop bar. Then the purse nail, the pusher piece and the purse string are loaded into the staple cartridge, and then the staple cartridge is put into the holder 1 to complete the preoperative use preparation of the surgical automatic purse stapler. After entering the operation implementation stage, the doctor opens the purse device through the handle 3, that is, the upper and lower clamping seats 1 are opened. Then let the tissue enter between the two clip seats from the open side and place it centrally on the lower clip seat 1, while releasing the safety lever 5, hold the handle 3 tightly until the hooks 4a, 4b are hooked together, so that the upper and lower clip seats 1 Close it completely, and finally open the handle 3 while opening the hooks 4a, 4b, move out the automatic purse string stapler, tighten the purse string, and complete the purse string suture at the tissue end.

By using the present invention, during operation, since the clip seat 1 and the clip seat connecting rod 2 of the surgical purse-string stapler are arranged in an "L" shape, the doctor performing the operation can observe the clip seat 1 very intuitively. That is to say, the doctor can directly observe the placement of the tissue on the clamp base 1 directly from the side of the clamp base connecting rod 2, and the line of sight will not be blocked by the clamp base connecting rod 2, and there is no need to swing the clamp base connecting rod left and right 2 to observe whether the left and right sides of the clip holder 1 have clamped the tissue well, which reduces the difficulty of the doctor's operation, is easier to use, and has a better effect, and has a good prospect for popularization and application.
