Description

Technical Field

[0001] The invention relates to the medical field, and in particular to a U-shaped rapid soft tissue rupture suturing device. Background Art

[0002] Soft tissue rupture is a common surgical injury in clinical practice, especially in high-energy trauma or sports medicine. Fast and reliable suturing is crucial to restoring function and reducing adhesion and infection risks. Traditional suturing technology relies on manual operation and has defects such as low efficiency, large trauma and poor stability. Existing suturing instruments still have significant technical bottlenecks in structural design, material adaptation and ease of operation.

[0003] Deficiencies in the U-shaped suture staple design: Some instruments use U-shaped metal staples (such as patent CN202311042275.7), which are fixed by retracting the staple legs through the staple cartridge pusher seat. However, the retraction process of the staple legs relies on mechanical pushing, which may cause deformation or incomplete closure of the staple legs due to differences in tissue thickness, thus affecting the mechanical strength.

[0004] The contradiction between operational efficiency and minimally invasiveness: For example, although the motor-driven suturing device can achieve continuous suturing, it needs to integrate complex structures such as motors and gear sets. It is bulky and difficult to adapt to minimally invasive scenarios such as laparoscopy.

[0005] Material biocompatibility defects: Metal nails need to be removed a second time, while absorbable materials (such as magnesium alloys) have insufficient tensile strength and their degradation rate does not match the soft tissue healing cycle, which can easily lead to early failure or inflammatory response. Summary of the invention

[0006] The problem to be solved by the present invention is to provide a U-shaped rapid soft tissue rupture suture device for suturing soft tissue in view of the above-mentioned deficiencies in the prior art.

[0007] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a U-shaped rapid soft tissue rupture suture device, comprising a first suture support member and a second suture support member, the first suture support member and the second suture support member are respectively provided with corresponding first suture through holes and second suture through holes, the first suture through holes and the second suture through holes are spaced 3mm to 7mm apart, a suture threading is formed between the first suture through holes and the second suture through holes, the first suture support member and the second suture support member are respectively connected with a first bottom member and a second bottom member below, the first bottom member is provided with a horizontal screw, the second bottom member is provided with a sleeve, the screw extends into the sleeve and is screwed therewith, the first bottom member and the second bottom member are respectively provided with corresponding first slide grooves and second slide grooves, a slide rod is arranged between the first slide groove and the second slide groove.

[0008] Furthermore, the first suture support member and the second suture support member are horizontally connected to a first horizontal rod and a second horizontal rod respectively, a movable hinge is formed between the first horizontal rod and the second horizontal rod, and the first horizontal rod extends outwardly to a third horizontal rod.

[0009] Furthermore, a slider capable of sliding on a slide rail on the second horizontal rod is disposed on the first horizontal rod, the second horizontal rod comprises an upper rod and a lower rod corresponding to each other vertically, and the slider is respectively located on the slide rails of the upper rod and the lower rod.

[0010] Furthermore, the first suturing support member and the second suturing support member are symmetrical structures along the vertical direction, and the first suturing support member includes an upper support member and a lower support member, and the upper support member can rotate on the lower support member.

[0011] Compared with the prior art, the present invention has the following beneficial effects: the present invention adjusts the positions of the first suture through hole and the second suture through hole by making the first suture through hole correspond to the second suture through hole, and rotating the swing angles of the first suture support member and the second suture support member according to different patient conditions; and then locks them through the mutual cooperation of the screw rod and the sleeve.
