Abstract
Description
Technical Field
[0001] The utility model relates to a medical automatic suturing device and a suturing thread. Background Art
[0002] At present, the most mainstream way to suture wounds after surgical operations is to use a needle holder to hold a curved needle with a thread on one end, pass it through the tissue to be sutured, and then tie a knot to complete the suture process. This requires a relatively open field of vision and sufficient operating space.
[0003] However, when suturing wounds in patients' mouths, conventional suturing methods often encounter obstacles due to the narrow oral space and the low level of cooperation of young patients.
[0004] A Chinese patent (application number: CN200910014754.1) attempts to solve a similar problem by designing a semi-automatic suturing device that can assist in the "suturing" process, while knotting requires the surgeon to operate. However, in reality, knotting requires a large operating space. Summary of the invention
[0005] The utility model provides a medical automatic suturing device, which is used to solve the problem of difficult suturing in an oral cavity with a small space, reduces the pain of the patient during the suturing process, and provides convenience for the doctor's operation.
[0006] The technical solution of the utility model to solve the above problems is: a medical automatic suturing device, which is special in that:
[0007] The invention comprises a vascular clamp body, wherein one end of the vascular clamp body is provided with a suture curved needle, and the other end of the vascular clamp body is provided with a retaining ring, the upper part of the retaining ring is provided with a retaining ring small hole, the lower part of the retaining ring is provided with a retaining ring large hole, the middle part of the vascular clamp end provided with the retaining ring is provided with a retaining ring, and the suture curved needle is provided with a groove on the side facing the retaining ring; when the vascular clamp body is tightened, the end of the suture curved needle passes through the retaining ring.
[0008] Furthermore, the surface of the retaining ring is provided with a granular raised structure, the retaining ring is made of hard latex, and the rest is made of metal. The hard latex with the granular raised structure can increase the friction between the retaining ring and the soft tissue and has a protective effect on the soft tissue.
[0009] Furthermore, the retaining ring is arranged outside the middle part of the vascular clamp end.
[0010] Furthermore, the root of the curved suture needle is fixed to the end of the vascular clamp, and the head of the curved suture needle is bent toward one side of the retaining ring.
[0011] In addition, the present invention also provides a suture thread used in conjunction with the above-mentioned medical automatic suture device, characterized in that:
[0012] The main body of the suture is an absorbable barbed suture, and the two ends of the suture are respectively a suture head and a retention tail, and the sizes of the suture head and the retention tail are larger than the size of the middle body of the suture.
[0013] Furthermore, the structure of the suture thread head is a spherical node.
[0014] Furthermore, the retaining tail is a Y-shaped structure.
[0015] Advantages of the utility model:
[0016] The medical automatic suturing device and suture thread of the utility model realize fully automatic suturing. The whole suturing process can be completed only by opening and closing the improved vascular clamp, thereby solving the problem of difficult suturing in the oral cavity with a small space, reducing the pain of the patient during the suturing process and providing convenience for the doctor's operation.

[0021] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is claimed, but merely represents the selected embodiments of the utility model.
[0022] Example 1
[0023] See also Figure 1 and Figure 2The utility model proposes a medical automatic suturing device, comprising a vascular clamp body 1, a suture curved needle 4 is provided at one vascular clamp end of the vascular clamp body 1, a retaining ring 5 is provided at the other vascular clamp end, a retaining ring small hole 6 is provided at the upper part of the retaining ring 5, a retaining ring large hole 7 is provided at the lower part of the retaining ring 5, a retaining ring 8 is provided at the middle part of the vascular clamp end where the retaining ring 5 is provided, the retaining ring 8 is used to fix the tail of the suture thread, and a groove is provided on the side of the suture curved needle 4 facing the retaining ring 5; when the vascular clamp body 1 is tightened, the end of the suture curved needle 4 passes through the retaining ring 5.
[0024] As a preferred embodiment of the utility model, except for the retaining ring 5 which is composed of hard latex with a granular protrusion structure on the surface, the rest of the device is made of metal. The granular hard latex on the surface can increase the friction between the retaining ring and the tissue and has a protective effect on the soft tissue.
[0025] As a preferred embodiment of the present invention, the retaining ring 8 is arranged outside the middle of the vascular clamp end, and when the vascular clamp body 1 is tightened, it will not interfere with the vascular clamp end on the other side of the vascular clamp body 1.
[0026] As a preferred embodiment of the utility model, the root of the suture needle 4 is fixed to the end of the vascular clamp, the head of the suture needle 4 is bent toward the side of the retaining ring 5, and the groove is arranged on the inner side of the head of the suture needle 4.
[0027] Example 2
[0028] See also Figure 3 The present invention also proposes a suture, which is used in conjunction with the above-mentioned medical automatic suture device. The main body of the suture is an absorbable barbed suture, which can only move in one direction after entering the tissue and cannot be retracted. The two ends of the suture are a suture head 9.1 and a retention tail 9.3, respectively. The suture head 9.1 and the retention tail 9.3 are made of soft latex and have a certain elasticity. The size of the suture head 9.1 and the retention tail 9.3 is larger than the size of the main body of the middle part of the suture, and the resistance of the retention tail 9.3 passing through the retention ring 8 is greater than the resistance of the suture head 9.1 leaving the small hole of the retention ring 5.
[0029] As a preferred embodiment of the present invention, the structure of the suture head 9.1 is a ball-shaped node; the retention tail 9.3 is a Y-shaped structure. Of course, the head and tail of the suture can be made into any shape as long as the specific retention conditions are met.
[0030] When the above-mentioned medical automatic suturing device and suture are used, the suture 9 is first passed through the retaining ring 8, the large hole 7 on the retaining ring and the small hole 6 on the retaining ring to fix it on the automatic suturing device. Specifically, the suture head 9.1 is embedded in the small hole 6 on the retaining ring, and the retaining tail 9.3 is clamped at the retaining ring 8 to obtain a section of taut suture. After the preparation work is done, the suture curved needle of the automatic suturing device is placed at the part to be sutured, the vascular clamp is tightened, the suture curved needle 4 passes through the tissue to be sutured and enters the retaining ring 5, the suture enters the groove on the suture curved needle 4, and then the vascular clamp is loosened. When the suture curved needle 4 leaves the retaining ring 5, the suture head 9.1 is first pulled out of the small hole 6, and the suture head 9.1 is clamped at one end of the groove. In the process of continuing to move away, the retaining tail 9.3 of the suture is also brought out of the retaining ring 8. Next, the suture body 9.2 follows the suture curved needle 4 through the tissue to be sutured, and after the retaining tail 9.3 is pulled to a position that fits the tissue surface, the excess suture on the suture curved needle 4 is cut off, and the suturing process is completed without tying a knot.
[0031] Since the suture 9 is made of absorbable material, when removing the suture, it is only necessary to remove the retaining tail 9.3 of the suture 9.
[0032] The above description is only an embodiment of the present invention, and is not intended to limit the protection scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly used in other related system fields, are also included in the protection scope of the present invention.
