Description

Anti-spill automatic purse

technical field

The utility model relates to a suturing device used in surgical operations, in particular to an overflow-proof automatic purse device, which belongs to the technical field of medical instruments.

Background technique

As far as the current surgical field is concerned, the purse-string stapler for surgery is a medical instrument commonly used when performing surgical operations on physiological tissues such as the intestinal tract. When suturing, purse string sutures are performed on the organ stump so that it can be firmly ligated after the central rod is placed. Existing automatic wallets are usually provided with a limiting device at one end of the upper and lower clamping seats, which are used to limit the opening degree of the upper and lower clamping seats and prevent the two from being separated. Moreover, the restricting device also has the function of preventing human tissue from overflowing.

However, in actual use, since the width of human tissue is not fixed, but relatively variable, the restricting device installed at one end of the upper and lower clamping seats cannot completely limit the overflow of these tissues, which will still cause human tissues to overflow the purse stapler. Therefore, often can influence the percussion of apparatus, cause part purse-string nail to form bad simultaneously, have brought many unfavorable factors to the normal implementation of operation.

Contents of the invention

The purpose of the utility model is to solve the above-mentioned problems existing in the prior art, and to provide an overflow-proof automatic purse.

The purpose of this utility model is achieved through the following technical solutions:

The anti-overflow automatic wallet includes a pair of upper and lower staple magazines and upper and lower clamping seats. The staple magazines are installed inside the clamping seats. The upper and lower clamping seats are provided with connecting rods for the clamping seats through injection molding. Shaped combination, so that the upper and lower clamping seats can be opened and closed, so that the suture surface is formed between the upper and lower nail bins. One end of the lower clamping seat is provided with a limit rod, wherein: the other end of the lower clamping seat relative to the limit rod is provided with an anti Overflow boss.

The above-mentioned anti-overflow automatic wallet, wherein: the position of the upper clamp seat relative to the anti-overflow boss is provided with a relief groove, and the width of the relief groove is equal to or greater than the width of the anti-overflow boss.

Further, the above-mentioned anti-overflow automatic wallet, wherein: the anti-overflow boss is rectangular or trapezoidal.

The outstanding substantive features and remarkable progress of the technical solution of the utility model are mainly reflected in: by adopting the anti-spill automatic purse device, the human tissue can be limited in the suturing surface formed by the staple magazine to prevent it from overflowing. This ensures that the surgical nails are well formed and the purse is completely formed, making full preparations for the next surgical operation and making the operation go smoothly.

Detailed ways

The anti-overflow automatic purse device shown in Figure 1 includes a pair of upper and lower staple bins 1 and upper and lower clip seats. The pins 5 are used to connect the rods 4 in a scissors-like manner, so that the upper and lower clip seats can be opened and closed, and a suture surface is formed between the upper and lower staple cartridges 1 . Simultaneously, similar to the traditional enterprise structure, a limiting rod 6 is provided at one end of the lower clamping seat 3 , and its special feature is that an anti-overflow boss 7 is provided at the other end of the lower clamping seat 3 relative to the limiting rod 6 . And, in order to better fit between the upper and lower clamp seats, the position of the upper clamp seat 2 relative to the anti-overflow boss 7 is provided with a relief groove 8, and the width of the relief groove 8 is equal to or greater than the anti-overflow boss. The width of overflow boss 7.

Furthermore, according to the needs of various operations, the anti-overflow boss 7 can be rectangular or trapezoidal, so as to limit the anti-overflow of tissues. Furthermore, the end of the clip seat connecting rod 4 can be equipped with a handle, so that the operator can more easily control the opening and closing of the clip seat connecting rod 4, and then realize the opening and closing state of the suturing surface formed by the staple cartridge 1. Relatively good control.

The specific operation process is as follows. The surgical nails and purse strings are placed in place during the surgical equipment stage. During the operation, the implementer first manipulates the handle to open the upper and lower clamping seats to a certain angle, and then places the broken end of the human tissue in the center on the suturing surface formed by the staple cartridge 1 . Due to the blocking of the anti-overflow boss 7, human tissue will not slip out from one end of the clamp seat, that is, no tissue will overflow to the outside of the suture surface formed between the upper and lower staple bins 1, which ensures that the tissues are well-organized during the closing process of the upper and lower clamp seats. a good shape. When the upper and lower clamping seats are completely closed, the anti-overflow boss 7 fits into the relief groove 8, which does not affect the final binding and sewing, and finally makes the purse perfectly formed.

From the above-mentioned implementation process, it can be clearly seen that by adopting the anti-overflow automatic purse device, human tissue can be confined in the suturing surface formed by the staple cartridge 1 to prevent it from overflowing. This ensures that the surgical nails are well formed and the purse bag is fully formed, making full preparations for the next surgical operation. The device has excellent application effects and is worthy of promotion and implementation in the same field to improve the existing operating environment.
