Embodiment Construction

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] combine figure 1 with figure 2 As shown, a step-by-step feed mechanism applied to continuous clamping pliers, including a pincer head 1 and a pincer head push rod 2 connected to the pincer head 1, moving the pincer head push rod 2 can drive the pincer head 1 is opened or clamped, the pincer head push rod 2 and the pincer head 1 can be connected by the common connection method of the clamp applicator in the prior art, so as to realize the opening and closing action of the control pincer head 1. The end of the pliers head push rod 2 away from the pliers head 1 is connected with a propulsion structure 3, and a first feed mechanism 5 and a second feed mechanism 6 are also provided between the drive handle 4 and the propulsion structure 3. The drive handle 4 The first feeding mechanism 5 pushes the propelling structure 3 into the...

Abstract

The invention belongs to the technical field of medical devices, and in particular relates to a step-by-step feeding mechanism applied to continuous clip applicators. The present invention aims at the problem that the tissue clip in the prior art will have a large automatic bounce action when it is pushed out of the clip applier, which brings inconvenience to the medical staff during the operation, and provides a clip applicator for continuous hair clipping. The step-by-step feeding mechanism of the pliers includes the pliers head and the pliers head push rod connected to the pliers head. The end of the pliers head push rod far away from the pliers head is connected with a propulsion structure, and a first The feed mechanism and the second feed mechanism, the drive handle pushes the propulsion structure into the first feed space through the first feed mechanism, and the drive handle pushes the propulsion structure into the second feed space through the second feed mechanism. The present invention can reduce the amplitude of the automatic spring-open action of the tissue clip, and then use the second feeding mechanism to slowly clamp until it is completely closed, so it is more suitable for the tissue clip that will automatically spring open when ejected.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a step-by-step feeding mechanism applied to continuous clip applicators. Background technique [0002] A clip applier is a surgical instrument used to clamp tissue clips during surgery. Usually, the tissue clips can be made of metal materials, such as titanium clips, or other materials, such as plastic clips. When the tissue clip is being clamped, it is necessary to push the tissue clip out of the clip applier first, and then use the pliers head to close the tissue clip to achieve clamping. However, some tissue clips, such as plastic tissue clips, will have a large automatic springing action when they are pushed out to the position of the clamp applicator, which brings inconvenience to the medical staff during the operation. [0003] For example, a Chinese utility model patent discloses a clamp applicator [application number: 202022036634.6]. The body is mo...
