Description

A kind of surgical tweezers for suturing

technical field

The invention relates to a surgical forceps used for suturing, and belongs to the technical field of medical appliances.

Background technique

In the current medical field, when performing anastomosis of bile ducts, intestinal tracts, ureters, blood vessels and other hollow organs, especially continuous sutures (accounting for about 90% of anastomosis), the bile duct space will become smaller and smaller as the suture operation progresses. The tight space makes getting those last few stitches rather difficult. Surgeons currently use two methods to solve this problem: the first method is to expand the space, which is to use surgical tools to open the part of the bile duct that has not been sutured, so as to obtain a larger operation space, but this method The method may cause damage to the tissues on both sides of the bile duct and cause adverse consequences to the patient's body; the second method is blind stitching, which is mainly based on the surgeon's experience in judging the position and angle of the needle. Suturing, this method is affected by many factors such as the experience of the surgeon, the actual physical condition of the patient, the environment of the operating site, etc. Once the suturing is performed improperly, it will be sutured to the wall opposite the bile duct, narrowing the lumen, and it will be later. Cause various complications, very unfavorable to patient's health.

Contents of the invention

Aiming at the above-mentioned problems in the prior art, the present invention provides a surgical forceps for suturing, which avoids suturing to the opposite wall of the bile duct without enlarging the patient's bile duct space.

In order to achieve the above object, the technical solution adopted in the present invention is: a surgical forceps for suturing, consisting of a first forceps arm and a second forceps arm, the first forceps arm and the second forceps arm are connected together by the proximal end; The first tweezers arm and the second tweezers arm have a first precision pliers and a second precision pliers at the far end respectively, and the precision pliers are arc-shaped; the inner corresponding positions of the first precision pliers and the second precision pliers are respectively provided with one or more A semicircular notch, the notch extends from the upper surface to the lower surface, the first precision pliers and the second precision pliers are provided with chamfers at the junction of the upper surface and the inner side, the chamfers of the first precision pliers and the second precision pliers Open symmetrically.

Further, two notches are respectively opened on the first precision forceps and the second precision forceps, and the two notches are arranged along the direction from the proximal end to the distal end.

Further, the outer surfaces of the first tweezers arms and the second tweezers arms have corrugated non-slip parts.

Further, the chamfers of the first precision pliers and the second precision pliers extend from the distal end to the notch.

The beneficial effect of the present invention is: hold the first tweezers arm and the second tweezers arm, the holding force will make the insides of the first precision forceps and the second precision forceps contact and stick together, then put the precision forceps into the bile duct, put After completion, use the needle holder to hold the suture needle and insert the needle, and sew the bile duct on one side first. Since the precise forceps are first placed in the bile duct to act as a lining, the needle tip of the suture needle will not be sewed to the opposite wall of the bile duct. The first precision forceps and the second precision forceps are provided with chamfers at the junction of the upper surface and the inside, and the insides of the first precision forceps and the second precision forceps are put into the bile duct when they are in contact with each other, so the needle tip of the suture needle will come from Move along the curved outline of the precision forceps in the V-shaped or U-shaped groove. After suturing one side of the bile duct, rotate the invention 180 degrees, put the precision forceps into the other side of the bile duct, and then insert the suture needle Pass through the through hole and the wall of the bile duct on the other side in turn. Since the suture needle is in the through hole and the precise forceps act as a lining in the bile duct, the tube opposite to the bile duct will not be sewed when suturing the other side of the bile duct On the wall, after the suture needle passes through the wall of the bile duct on the other side, the needle holder keeps the state of holding the needle, clamps the suture needle with the precise forceps of the present invention, and then loosens the needle holder, and uses the needle holder to pass through the other side of the bile duct wall. The suture needle on one side of the bile duct wall is pulled out from the bile duct wall. After the bile duct on both sides is sutured, loosen the first forceps arm and the second forceps arm so that there is a gap larger than the suture needle between the two, and then take it out In the present invention, the single cycle process of suturing the bile duct is thus completed, and the above steps are repeated until the bile duct is completely sutured, and the bile duct can be sutured conveniently by using the present invention, even if the bile duct at the end of the suturing space is small, there is no need to expand the bile duct space, which is beneficial to doctors The requirements for factors such as experience and operating site environment are low, the suture effect is good, and the side effects on patients are small.

detailed description

The present invention will be further described below in conjunction with accompanying drawing.

As shown in Fig. 1 and Fig. 2, the surgical tweezers used for suturing are composed of a first tweezer arm 12 and a second tweezer arm 14, and the first tweezer arm 12 and the second tweezer arm 14 are connected together by a proximal end 16 The first tweezers arm 12 and the second tweezers arm 14 have a first precise pliers 20 and a second precise pliers 22 at the far end 18 respectively, and the precise pliers are arc-shaped; the inside of the first precise pliers 20 and the second precise pliers 22 28 corresponding positions are provided with one or more semicircular notches 32 respectively, and the notches 32 extend from the upper surface 24 to the lower surface 26. A chamfer 34 is provided, and the chamfers 34 of the first precision pliers 20 and the second precision pliers 22 are symmetrically opened. As shown in Figure 3, after the first precision pliers 20 and the second precision pliers 22 are fitted together, the two semicircular The notch 32 forms a through hole 38, and the two chamfers 34 form a V-shaped or U-shaped groove.

How to use: Take the end-to-end anastomosis of the bile duct as an example, hold the first tweezers arm 12 and the second tweezers arm 14, the holding force will make the inner side 28 of the first precision forceps 20 and the second precision forceps 22 contact and fit together, and then press Put the precision forceps into the bile duct. After putting it in place, use the needle holder to hold the suture needle and insert the needle. First, sew the bile duct on one side. Since the precision forceps are placed in the bile duct first to act as a shield, the needle tip of the suture needle will not Sewn to the tube wall opposite to the bile duct, the first precision clamp 20 and the second precision clamp 22 are provided with a chamfer 34 at the junction of the upper surface 24 and the inner side 28, and the inner side 28 of the first precision clamp 20 and the second precision clamp 22 It is put into the bile duct only when they are in contact with each other, so the needle tip of the suture needle will move from the V-shaped or U-shaped groove along the arc contour of the precision forceps. Put the precision forceps into the bile duct on the other side, and then pass the suture needle through the through hole 38 and the bile duct wall on the other side in sequence, because the suture needle is in the through hole 38 and the precision forceps play the role of a lining in the bile duct Therefore, when the other side of the bile duct is sutured, it will not be sewed to the opposite wall of the bile duct. After the suture needle passes through the other side of the bile duct wall, the needle holder maintains the state of holding the needle, and is clamped by the precise forceps of the present invention Hold the suture needle, then loosen the needle holder, pull out the suture needle that penetrates the bile duct wall on the other side from the bile duct wall with the needle holder, after the bile duct on both sides is sutured, slightly loosen the first tweezers arm 12 and The second tweezers arm 14 leaves a gap greater than the sewing needle between the two, and then takes out the present invention, thus completing the single cycle process of bile duct suture, repeating the above steps until the bile duct is fully sutured, using the present invention can be convenient Suture the bile duct, even if the final suture space is small, there is no need to expand the bile duct space, and the requirements for factors such as doctor experience and operating site environment are low, the suture effect is good, and the side effects on patients are small.

The inner sides 28 of the first precision pliers 20 and the second precision pliers 22 are respectively provided with two semicircular gaps 32 along the proximal end 16 to the corresponding position of the distal end 18 direction, because the semicircular gap 32 is along the proximal end 16 direction. The direction of the distal end 18 is arranged, so the distances between the two semicircular openings 32 and the distal end 18 are different. In the actual operation, the diameters of different hollow organs are different, and the diameters of the same hollow organs of different people are also different. Therefore, the inner side 28 of the first precision forceps 20 and the second precision forceps 22 are respectively provided with two semicircular gaps 32 along the corresponding positions from the proximal end 16 to the distal end 18, which can be more practical in actual surgery, and can be used according to the hollow organ. The size of the diameter, flexibly select the through hole 38 that the suture needle needs to penetrate and is made up of the semicircular gap 32.

The outer surfaces of the first tweezers arm 12 and the second tweezers arm 14 have corrugated anti-slip parts, which can be held more stably during use, prevent slipping, and avoid affecting the operation.

In order to make the suturing needle move more conveniently in the V-shaped or U-shaped groove, the chamfer 34 of the first precision pliers 20 and the second precision pliers 22 extends from the distal end 18 to the gap 32, even if the chamfer 34 does not extend to the gap The position of 32 also does not affect the use of the present invention.
