Description

Technical Field

[0001] The utility model relates to the technical field of purse-string suturing of umbilical blood vessel catheters, in particular to a purse-string suturing device for umbilical blood vessel catheters. Background Art

[0002] Umbilical catheter puncture in newborns is a common procedure for critically ill newborns and premature infants after birth. It is used to monitor arterial blood gas, infuse rescue drugs, and perform repeated blood and fluid transfusions. After catheterization, the operator needs to use a suture needle to purse-string the umbilical catheter and the umbilical cord to fix them. However, in actual operation, manual suturing with sutures can easily cause loose purse-string sutures and loose sutures, which can lead to complications such as umbilical catheter dislocation and bleeding.

[0003] The purse-string suture device proposed in the Chinese utility model patent application number: CN201220725437.8 comprises: an upper and a lower clamp seat hinged to each other into a scissor shape, a nail magazine assembly is provided at the front end of the upper and lower clamp seats, the nail magazine assembly comprises a nail magazine and nails, a nail pusher and a purse string arranged therein, a wire pressing groove for accommodating the purse string is provided on the nail magazine, the wire pressing groove comprises a sliding portion, a closing portion and a fixing portion, the maximum width of the cross section of the fixing portion is greater than the diameter of the purse string, and the width of the cross section of the closing portion is less than the diameter of the purse string. The suture device is specially used for purse-string suture of adult umbilical vascular catheters, and is not suitable for umbilical vascular catheterization of neonates. At the same time, the lack of suture holes during use makes the suture accuracy relatively low; the suction tube of the suture device lacks an anti-slip cover during use, and is easy to fall off. Therefore, we make improvements on this and propose a purse-string suture device for umbilical vascular catheters. Utility Model Content

The triangular hole and the round hole help to improve the air permeability and accuracy, and reduce the operational error of the purse-string suturing of the umbilical vascular catheter. The suture device has a simple structure and is easy to operate, and medical staff can quickly master the method of use. It is made of medical silicone material, has good biocompatibility and corrosion resistance, and ensures the safety and reliability of the purse-string suturing process of the umbilical vascular catheter.

[0017] To make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be described clearly and completely in conjunction with the accompanying drawings. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments.

[0018] Therefore, the following detailed description of the embodiments of the utility model is not intended to limit the scope of the utility model for which protection is sought, but merely represents some embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. It should be noted that the embodiments of the utility model and the features and technical solutions in the embodiments can be combined with each other without conflict. It should be noted that similar numbers and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0019] Example 1: Please refer to Figure 1-Figure 4 A purse-string suture device for an umbilical vascular catheter includes a suture needle 1 and a suture sleeve 2. The suture needle 1 is connected to a suture thread 101. The suture thread 101 and the suture sleeve 2 are provided with a suture hole 201, and the interior of the suture sleeve 2 is provided with a sleeve hole 202. A triangular hole 203 is provided at the end of the suture sleeve 2, and four triangular holes 203 are provided and are symmetrically arranged. A circular hole 204 is provided at the center of the triangular hole 203. The pipeline 3 is made of transparent plastic material. A sleeve cover 5 is provided on the suture sleeve 2.

[0020] The suture sleeve 2 is made of medical silicone. The design of the umbilical vascular catheter purse-string suture device simplifies the umbilical vascular suture process, allowing medical staff to complete the suture task more quickly and accurately. The triangular hole 203 and the round hole 204 help to improve air permeability and accuracy, effectively reducing the umbilical vascular catheter purse-string suture time and error.

[0021] The suture sleeve 2 is made of medical silicone material, which has good biocompatibility and corrosion resistance, and can ensure the safety and reliability of the purse-string suture process of the umbilical blood vessel catheter. At the same time, the connection between the suture needle 1 and the suture 101 is firm, which effectively avoids the risk of the suture 101 falling off or breaking during the purse-string suture process of the umbilical blood vessel catheter. The purse-string suture device for the umbilical blood vessel catheter mainly uses the combination of the suture needle 1 and the suture 101 to close the umbilical blood vessel by purse-string suture. The circular hole 204 can be used to guide the suture needle 1 to pass through, and the triangular hole 203 can help improve the air permeability and accuracy.

[0022] During the storage process, the cover 5 on the suture sleeve 2 can protect the suture hole 201. Since the suture sleeve 2 is made of medical silica gel, it has certain elasticity and flexibility, so it can adapt to umbilical blood vessels of different sizes and shapes.

[0023] The working process of the utility model is as follows: first, ensure that the umbilical vascular catheter purse-string suture device and its accessory suture 101 are in a sterile state. Place the umbilical vascular catheter purse-string suture device on the umbilical vascular part to be sutured, ensure that the suture sleeve 2 covers the area to be sutured, and the triangular hole 203 can help improve air permeability and accuracy.

[0024] The umbilical blood vessel is inserted into the umbilical cord through the circular hole 204 of the suture sleeve 2, wherein the diameter of the circular hole 204 can be selected according to the diameter of different umbilical blood vessels. A suture 101 is inserted into the suture needle 1, which is arranged on the outside of the suture sleeve 2. The suture needle 1 is inserted into the suture hole 201 to perform purse-string suture on the umbilical blood vessel catheter.

[0025] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or replacement of the present invention; and all technical solutions and improvements that do not depart from the spirit and scope of the present invention are included in the scope of the claims of the present invention.
