The stapler is fixed on both sides of the wound for suturing. This technical solution is simple to operate, shortens the operation time, and the tissue suturing is firm and reliable. However, in the application There are still some defects in the process that need to be improved.

Before suturing with the stapler, the doctor clamps the wound with surgical forceps to make it anastomose with one hand, and fixes the stapler on both sides of the wound with adhesive strips with the other hand. However, the state of the wound is often linear, and the surgical forceps can only clamp If you hold one end, the other end of the wound may not be in a state of matching with each other. In this state, it is extremely inconvenient to correct the bonding position of the adhesive strip or adjust the degree of matching of the two sides of the wound.

In addition, during the wound suturing process, the needles are in a waiting state, and the needles currently used on the market are small and sharp, and there is a risk of the needles falling or being injected into the operation area during the operation, which has a certain impact on the safety of patients. threat.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

As shown in Figures 1 to 5, the utility model provides a surgical stapler, comprising a suturing component 1 and a fixing component 2, the suturing component 1 is installed on the upper end of the fixing component 2, and the inner side of the fixing component 2 is provided with a movement groove 21 for suturing The member 1 slides along the linear direction where the movement groove 21 is located at the upper end of the fixed member through the movement groove 21;

The suturing component 1 includes a staple cartridge 11 that moves linearly in the movement groove 21. One end of the staple cartridge 11 is movably connected with a firing assembly 12 for driving the needles in the staple cartridge 11 to be ejected. The nail groove 13, the nail outlet groove 13 is provided with a closing plate 14 connected with the firing assembly 12;

The bottom of the fixing member 2 is movable to be provided with a set of fixing seats 22 which are respectively adsorbed on both sides of the place to be sutured. The fixing seats 22 are connected to each other through a width adjustment assembly 23. relative distance between them.

In the application of the utility model, the fixing member 2 is fixed on both sides to be sutured by the fixing seat 22, and the relative distance between the reorganized fixing seat 22 is changed by adjusting the width adjustment assembly 23, and then the anastomotic openings on both sides of the wound adsorbed by the fixing seat 22 are opposite to each other. The distance is changed, and the two sides of the wound are matched in a better state by adjusting the width adjustment component 23 and the state of the wound, and after the muscle or organ epidermis on both sides of the wound is subjected to the opposing clamping force of the fixing seats 22 on both sides, the wound not only corresponds to Anastomosis, or the wound is in a tight and raised state, so that the force of the needle will be applied during the subsequent suturing process.

During this fixation process, the width adjustment assembly 23 can be adjusted by bolt helical or hinged, which can be selected according to the wound condition. When suturing an organ wound, the hinged point is rotated to change the closeness of the wound. When the trauma wound is sutured, the bolt rotation can be adjusted better than the force adjustment compared with the hinge adjustment.

When the utility model is suturing a wound, the firing assembly 12 is used to shoot the needles in the staple cartridge 11, and the firing assembly 12 is driven to fire and keep the staple cartridge 11 from one end of the wound to the other end along the movement groove 21. A linear mechanical suture completes the wound closure. The nail needles fired by the firing assembly 12 are shot out through the nail outlet groove 13, and nailed into both sides of the wound to tightly bite the wound. At the same time, one end of the nail outlet groove 13 is provided with a closing plate 14. The closing plate 14 closes the nail outlet groove 13 in a static state so that the needles in the warehouse body 111 cannot be ejected. 12 keeps moving at the same frequency, and then ensures that only when the firing assembly 12 is driven, the closing plate 14 moves so that the nail groove 13 is no longer kept closed, which increases the safety of the utility model and avoids the possibility that the nail needle enters the wound during the operation. risk.

In order to ensure that the staple cartridge 11 slides in the movement groove 13 along the linear direction where the movement groove 13 is located, the staple cartridge 11 includes a cartridge body 111, and sliders 112 are arranged on both sides of the cartridge body 111. The block 112 is a slide rail 113 whose shape and size coincide with each other, and the staple cartridge 11 is slidably connected to the slide rail 113 through the slide block 112 to perform sliding movement relative to the movement groove 13 .

On this basis, the relative displacement of the fixing base 22 relative to the fixing member 2 can also be slidably displaced by referring to the sliding connection between the sliding block 112 and the sliding rail 113 .

The closing plate 14 is movably fitted at the bottom of the cartridge body 111, and the closing plate 14 is provided with a hole with the same specification as the outlet of the nail outlet groove 13, and the closing plate 14 moves back and forth along the straight line where the staple cartridge 11 is located. When the firing assembly 12 is driven, the closing plate 14 is simultaneously driven to perform a linear sliding motion along the straight line where the staple cartridge 11 is located and the straight line where the moving groove 21 is located, and the exit of the nail outlet slot 13 gradually changes from intersecting with the hole on the closing plate 14 to coincide state.

One end of the closure plate 14 is movably connected to the firing assembly 12 through a fixedly connected traction assembly 15 , and the other end of the closure plate 14 is provided with an elastic assembly 16 . The traction assembly 15 is a non-elastic traction rope, one end is fixedly connected to one end of the closing plate 14, the other end is fixedly connected to a fastener and the fastener is movably attached to one side of the firing assembly 12, and the non-elastic traction rope runs through the fixed pulley structure. The elastic assembly 16 is an elastic spring, the elastic upper limit of which is greater than the motion potential energy of the firing assembly 12, and the elastic spring is a reset spring that gives a force in the opposite direction to the closing plate 14 in the direction of movement, for resetting the closing plate 14.

In order to ensure that the firing assembly 12 pulls the closing plate 14 to open and close the nail outlet slot 13 , the firing assembly 12 fires the needles at a distance equal to the distance that the closing plate 14 moves along the movement slot 21 .

To further ensure the adsorption effect of the fixing seat 22 on both sides of the wound, an adhesive layer is provided at the bottom of the fixing seat 22 .

The above embodiments are only exemplary embodiments of the present application, and are not intended to limit the present application, and the protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent replacements to the present application within the spirit and protection scope of the present application, and such modifications or equivalent replacements shall also be deemed to fall within the protection scope of the present application.
