Problems solved by technology

[0003] The grasping forceps of laparoscopic surgery are relatively commonly used tools in the process of laparoscopic surgery. In the existing technology, most of the grasping forceps of laparoscopic surgery adopt two sets of hinged connecting rods. The opening and closing of the rod realizes the clamping of the grasping forceps, which is inconvenient to adjust and inflexible to use, which makes the operation process inconvenient

Embodiment 1

[0025] see Figure 1~4 , in an embodiment of the present invention, a grasper for laparoscopic surgery, comprising an outer support sleeve 3 and a middle support sleeve 2 disposed inside the outer support sleeve 3, a lower clamping plate 12 is provided at the top of the outer support sleeve 3 And the inner wall of its lower end is provided with threads, the upper end of the middle support sleeve 2 protrudes from the outer support sleeve 3 and is provided with an upper clamping plate 13 that cooperates with the lower clamping plate 12, and the outer periphery of the lower end of the middle support sleeve 2 is rotated. There is a first threaded sleeve 4 that is threadedly matched with the lower end of the outer support sleeve 3, and the first threaded sleeve 4 is rotated to drive the middle support sleeve 2 to slide upward, so that the upper clamping plate 13 is separated from the lower clamping plate 12, which is convenient for grasping the human body Tissue; the inner wall of ...

Embodiment 2

[0033] see Figure 1~2 , in the embodiment of the present invention, a grasper for laparoscopic surgery, in order to enhance the sealing effect of the device, on the basis of embodiment 1, an elastic sealing sleeve 10 is also provided on the periphery of the leak-proof sliding sleeve 11, The elastic sealing sleeve 10 is made of a material with relatively high elasticity, which may change elastically with the size of the opening within a certain range, which can avoid direct contact between the leak-proof sliding sleeve 11 and the opening, causing wear and tear, and can also enhance the sealing effect.

[0034] The working principle of the present invention is:

[0035] When working, hold the first handle 9 and the second handle 7, place one end of the device on the site to be operated, and use the leak-proof sliding sleeve 11 that is sleeved with an elastic sealing sleeve 10 to block the opening to prevent the internal liquid from flowing out and prevent external leakage. Bac...

Abstract

The invention discloses grasping forceps used for laparoscopic surgery. The pic surgery comprise an outer supporting sleeve and a middle supp comprise an outer supporting sleeve and a middle supporting sleeve arranged in the outer supporting sleeve; the top end of the outer supporting sleeve is provided with lower clamping plates and the lower end of the outer supporting sleeve is in threaded connection with the middle supporting sleeve with upper clamping plates; the lower end of the middle supporting sleeve is in threaded connection with an inner supporting rod with a cutting blade; the periphery of the outer supporting sleeve is further provided with a leakage-proof device. According to the grasping forceps, with the cooperation of the outer supporting sleeve, the middle supporting sleeve and the inner supporting rod, clamping and cutting are realized; with the cooperation of a storage groove and the cutting blade, the cutting blade is prevented from injuring human tissues by accident, and the safety of the grasping forceps is improved; a leakage-proof sliding sleeve and an elastic sealing sleeve made of a material with relatively high elasticity are employed to block an opening, and the elastic sealing sleeve may elastically change along with the size of the opening within a certain range, so that not only can the situation that abrasion is caused by direct contact betweenthe leakage-proof sliding sleeve and the opening be avoided, but also the sealing effect can be enhanced, thereby preventing outflowing of internal liquid from, and meanwhile, avoiding entering of external bacteria.

Description

technical field [0001] The invention relates to the technical field of surgical instruments, in particular to a grasper for laparoscopic surgery. Background technique [0002] Laparoscopic surgery is a newly developed minimally invasive method, which has the characteristics of small wound, low damage and fast recovery time. With the rapid development of industrial manufacturing technology, the integration of related disciplines has laid a solid foundation for the development of new technologies and methods. Based on the foundation, coupled with the increasingly skilled operation of doctors, many open operations in the past have now been replaced by endovascular surgery, greatly increasing the chances of surgical options. [0003] The grasping forceps of laparoscopic surgery are relatively commonly used tools in the process of laparoscopic surgery. In the existing technology, most of the grasping forceps of laparoscopic surgery adopt two sets of hinged connecting rods. The o...
