本发明的工作原理：医生的食指和拇指分别插入第一手扣15和第二手扣7，食指和拇指捏合，带动第一钳杆1和第二钳杆4通过铰接轴6与铰接块14的铰接配合转动张开，即夹合钳头和副钳机构张开，将夹合钳头和副钳机构伸入需要夹持的患处，然后食指和拇指捏合张开，则夹合钳头和副钳机构闭合，对患处进行夹持；The working principle of the present invention: the doctor's index finger and thumb are inserted into the first hand buckle 15 and the second hand buckle 7 respectively, the index finger and thumb are pinched, and the first forceps rod 1 and the second forceps rod 4 are driven through the hinge shaft 6 and the hinge block 14. The hinge cooperates to rotate and expand, that is, the clamping forceps head and the auxiliary forceps mechanism are opened, and the clamping forceps head and the auxiliary forceps mechanism are extended into the affected area to be clamped, and then the forefinger and thumb are pinched and opened, then the clamping forceps head and the auxiliary forceps mechanism are opened. The auxiliary forceps mechanism is closed to clamp the affected area;
当患处的形状不规则时，将连接螺杆5向螺孔16外旋出，连接螺杆5拉动旋转头8向着第一手扣15的方向拉动，即铰接板11拉动第一连杆9和第二连杆10，第二连杆10带动第一连接板19转动，即带动第一连接板19的转轴孔一围绕转轴18转动，即第一钳头2张开，第一连杆9带动第二连接板22转动，即带动第二连接板22的转轴孔二围绕转轴18转动，即第二钳头3张开，将第一钳头2和第二钳头3以及夹合钳头放置在不规则的患处，将连接螺杆5向螺孔16内旋入，第一钳头2和第二钳头3闭合夹住不规则患处，夹住后停止拧动，即自锁，然后食指和拇指捏合张开，则夹合钳头和第一钳头2以及第二钳头3配合闭合，对不规则患处进行夹持；夹持完成后，反向连接螺杆5向螺孔16外旋出，第一钳头2和第二钳头3张开，食指和拇指捏合，松开患处。When the shape of the affected area is irregular, the connecting screw 5 is unscrewed to the outside of the screw hole 16, and the connecting screw 5 pulls the rotating head 8 towards the direction of the first hand buckle 15, that is, the hinge plate 11 pulls the first link 9 and the second The connecting rod 10 and the second connecting rod 10 drive the first connecting plate 19 to rotate, that is, drive the shaft hole of the first connecting plate 19 to rotate around the rotating shaft 18, that is, the first clamp head 2 is opened, and the first connecting rod 9 drives the second connecting rod 19. The connecting plate 22 rotates, that is, the rotating shaft hole 2 of the second connecting plate 22 is driven to rotate around the rotating shaft 18, that is, the second clamp head 3 is opened, and the first clamp head 2, the second clamp head 3 and the clamping clamp head are placed in different positions. For a regular affected area, screw the connecting screw 5 into the screw hole 16, the first forceps head 2 and the second forceps head 3 are closed to clamp the irregular affected area. Open, the clamping jaws and the first jaws 2 and the second jaws 3 cooperate and close to clamp the irregular affected part; The first forceps head 2 and the second forceps head 3 are opened, and the index finger and thumb are pinched to loosen the affected area.
综上，本发明提供了一种医疗手术钳，采用夹合钳头和副钳机构配合，可夹持夹紧患处，同时副钳机构采用第一钳头2和第二钳头3配合，提供与夹合钳头和副钳机构的夹持方向相垂直的夹持，可更好的夹持夹紧不规则的患处，避免造成二次损伤；通过连接螺杆5与螺孔16的配合，调节第一钳头2和第二钳头3的张开角度，适用范围广，且夹紧后即自锁，避免松动，本发明结构简单，生产制造简单。To sum up, the present invention provides a medical surgical forceps, which adopts the cooperation of the clamping forceps head and the auxiliary forceps mechanism, which can clamp and clamp the affected area, and meanwhile, the auxiliary forceps mechanism adopts the cooperation of the first forceps head 2 and the second forceps head 3 to provide The clamping perpendicular to the clamping direction of the clamping head and the vice clamping mechanism can better clamp and clamp the irregular affected area and avoid secondary damage; The opening angles of the first clamp head 2 and the second clamp head 3 have a wide range of applications, and they are self-locking after being clamped to avoid loosening. The present invention has a simple structure and is simple to manufacture.
