Description
Technical Field
The invention relates to a medical article, in particular to a doctor biological clip continuous-sending clip applying technology, and specifically relates to a semi-automatic clip sending mechanism for a medical continuous-sending clip applying machine.
Background
In endoscopic surgery, blood vessels need to be clamped to prevent bleeding when organs and tissues are severed. At present, two kinds of clip appliers are mainly adopted to solve the problem of blood vessel clipping. One is a reusable medical biological clip single-hair clip applier, which can effectively solve the problem of blood vessel ligation in endoscopic surgery, but a doctor needs to take out the clip applier from the human body after clamping each biological clip, and then the clip applier is handed to a nurse, the nurse puts a new hemostatic clip into the jaw mouth of the forceps head, and then the nurse hands the doctor to implement secondary clipping, and the operation is repeated in this way, and two persons are needed to operate each time the clipping is completed, so that a long time is spent; and the clip applier repeatedly goes in and out of the human body, so that the risk of infection and bleeding is increased.
The other is a medical titanium clip repeating clip applier which can realize continuous firing, but is a disposable medical instrument which increases the operation cost. Meanwhile, the titanium clip for ligation has no elasticity, is easy to conduct electricity, cannot be absorbed by a human body, and affects the MRI image examination after the operation.
Chinese patent 201510009673.8, "automatic repeating plastic vascular forceps and clip cartridge", is a novel clip applier invented for overcoming the drawbacks of the above two clip appliers, which can perform the clip appliers continuously, and the hemostatic clip used belongs to a biological clip, but the design thereof has certain disadvantages:
firstly, the biological clips are easy to fall off or deviate when being continuously filled. The patent is designed in such a way that a hemostatic clamp in a hemostatic clamp box is abutted against a spring mechanism set by a clamp applying clamp, the spring mechanism stores energy before the hemostatic clamp is not triggered, after a trigger mechanism is started, the spring mechanism enters an energy release stage, and the hemostatic clamp enters a clamp applying platform (a filling clamp) at the forefront end of the clamp applying clamp under the pushing of the spring mechanism. After the vessel is clamped, the second hemostatic clamp automatically enters the clamping platform under the action of the spring mechanism. The disadvantages of this design are: the hemostatic clamp enters the clamping platform automatically under the action of energy released by the spring mechanism, and the energy release stage of the spring mechanism does not have a corresponding control mechanism in the clamping clamp. Therefore, when the previous hemostatic clamp is used, the latter hemostatic clamp is automatically ejected to enter the clamping platform, that is, the latter hemostatic clamp may collide with the previous hemostatic clamp to cause dislocation, thereby affecting the reliability or stability of the operation.
Secondly, the front end of the clip applier designed in the patent is provided with a fixed clip applier platform which is fixed in the clip applier process, and ligation of the vascular clip can be implemented only by a turnover mechanism, so that the clip applier acts in a single linkage manner, and the risk of insufficient clipping force is possible when clipping and closing the hemostatic clip.
To 201510009673.8, chinese patent 2016104370454, "a semi-automatic medical continuous-delivery clip applier with a clip magazine" provides a better solution, but in the actual use process, because the clip mouth is longer, the original state of the next clip is affected only by the fact that the next clip is delivered to the closing part, the first clip cannot be pushed in place and cannot be closed, and the destruction of the subsequent clip for pushing is affected, which may cause the 2016104370454 patent to lack practical value, and has great operation difficulty and low success rate. In addition, in the actual use process, as the section structure of the guide groove of the clamp mouth part for the blood vessel clamp to pass through and guide is a square structure, the blood vessel clamp can leave the guide groove due to uneven stress in the moving process, and the normal conveying of the blood vessel clamp is influenced. These are all in need of improvement.
