Clamp capable of being opened, closed and locked through guide block and intestinal canal implanting instrument

Abstract

A clamp capable of being opened, closed and locked through a guide block comprises a sleeve, an axial protection pipe, a control line, a control mechanism and at least two clamping legs, the guide block slides along guide faces in a far-and-near mode to control opening, closing and rotation of the clamping legs, and the operation process has good controllability. The clamping surfaces are used for locking the locking structure formed by the guide blocks, so that the clamp can be firmly fixed on the corrugated and zigzag intestinal wall, and the locking structure is positioned in the sleeve, so that the clamp is not easy to fall off due to intestinal tract movement or friction of excrement; according to the improved intestinal tract implanted tube instrument based on the clamp, direct fixation or pre-fixation of the intestinal tract implanted tube can be achieved by opening, closing and locking the clamp, the difficulty of adjusting an endoscope and the intestinal tract implanted tube when the endoscope is taken out for the first time can be effectively reduced, and the step of fixing a fixing wire ring by applying a titanium clamp through the endoscope can be omitted or reduced.

Description

technical field [0001] The invention relates to a medical device for endoscope application, in particular to a clamp which is opened and closed through a guide block and an intestinal tube planting device with the clamping device. Background technique [0002] Endoscopic titanium clips (referred to as titanium clips) are a type of medical device that achieves suture and hemostasis of tissues, especially the digestive tract. In clinical practice, it is not only used for tissue suture and hemostasis, but also used for internal fixation of medical equipment, such as the current endoscopic intestinal tube implantation (Transendoscopic Enteral Tubing, TET), using endoscope-guided titanium clips, through titanium Clamping and fixing the fixed wire ring and tissue of the TET tube, and realizing the whole colon drug delivery through intestinal tube implantation, colonic fecal bacteria transplantation and other treatments have been widely used and replaced the traditional rectal drug...

AI Technical Summary

Problems solved by technology

[0008] Since the locking structures of these two types of clips are exposed, the purpose is to achieve relatively good tissue suturing and hemostasis effects, and to achieve self-detachment after tissue healing; however, when completing endoscopic intestinal tube implantation, Since the TET tube needs to be kept in the intestinal tract for several weeks to several months, and the exposed locking structure of these two types of titanium clips is easily separated by the peristalsis of the intestinal tract or the friction of the feces in the intestinal tract, so the indwelling time in the intestinal tract is relatively short; and In the event that the titanium clip falls off and the TET tube cannot be indwelled, the colonic route of endoscopic intestinal tube implantation again requires the patient to fast again, insert an endoscope, and perform new TET tube implantation and fixation. Bring discomfort to the patient, and is not conducive to the recovery of the patient's condition
