Minimally invasive surgical suture end locking device, method and operating gun body

Abstract

The present invention relates to the technical field of medical devices, in particular to a minimally invasive surgical suture end locking device, comprising: a hook assembly, a clamping structure, a power rod and an outer catheter; the hook assembly includes a flexible material The ring structure and the force application end; the clamping structure squeezes the locking nail; the power rod squeezes the clamping structure through linear motion; the outer conduit is provided with a through hole, and the through hole is set on the side of the contact position between the clamping structure and the power rod. Allows for partial suture exit through the penetrating area. The present invention provides a device that can directly tighten and lock the suture at the proximal end of the position where the suture is led out from the human body tissue. It is easier to control the suture tightness of the suture to the tissue, avoiding the control difficulty caused by the excessive length of the suture thread and its own elasticity. The present invention also claims to protect the use method and the operating gun body of the minimally invasive surgical suture end locking device.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a minimally invasive surgery suture end locking device, method and operating gun body. Background technique [0002] In the current minimally invasive surgery and interventional surgery, it is necessary to cut a certain wound on the patient's body so that instruments such as endoscopes or interventional catheters can be inserted into the human body, and the tissue suture and the end of the suture line are completed in the patient's body. fixed. [0003] Among the fixation methods for the ends of the sutures, it is more conventional to perform multi-channel knotting and locking, that is, to perform multi-channel locking by twisting and knotting the ends of the sutures in the patient's body through related instruments, so as to avoid subsequent loose. However, after the operation is completed, due to the movement of the relevant tissues of the human body during life activ...

Problems solved by technology

[0005] When using the existing locking device to tighten the suture to ensure the effectiveness of the suture, it needs to be realized by a structure that can be used to tighten the suture outside the human body. In this way, the thread of the suture is longer, making the suture The distance the thread is stretched is relatively large, so it is difficult to control the tension of the suture thread actually required after suturing
