YY/T 1472.1-2016 Thoracic minimally invasive instruments - Part 1: Dual pivot surgical clamps
1 Scope
This part of YY/T 1472 specifies the classification, requirements, test methods, inspection rules, marking and instructions for use, packaging, transportation and storage requirements for dual pivot surgical clamps.
This part is applicable to dual pivot surgical clamps (hereinafter referred to as clamps) for mini-thoractomy:
——Minimally invasive tissue clamp, for clamping tissues and organs, such as lung lobes and lymph nodes;
——Minimally invasive separation ligation clamp, for separating target organs, such as blood vessels and tissues;
——Minimally invasive vascular clamp, for clamping and blocking blood vessels;
——Minimally invasive needle clamp, for clamping a suture needle.

3 Product classification
3.1 Structural type
3.1.1 Clamps include minimally invasive tissue clamp, minimally invasive separation ligation clamp, minimally invasive vascular clamp and minimally invasive needle clamp (hereinafter referred to as tissue clamp, separation ligation clamp, vascular clamp and needle clamp).
3.1.2 A clamp is mainly composed of clamp head, sliding rod, fixed rod, handle, box joint shaft for handle joint and box joint shaft for clamp head joint. The handles are classified into two types: ring handles (with or without locking teeth) and spring handles (with locking teeth), as shown in Figure 1. The clamp heads may be made to be straight, curved or 90° curved, as shown in Figure 2. The working face of a clamp may be made to be toothless, toothed or with reticulated teeth, as shown in Table 1.
The clamp structure may also be designed and determined by the manufacturer itself.
