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 for laparoscopic surgery. The grasping forceps comprise an outer supporting sleeve and a middle supporting sleeve arranged in the outer supporting sleeve, a lower clamping plate is arranged at the top end of the outer supporting sleeve, the lower end of the outer supporting sleeve is in threaded connection with the middle supporting sleeve with an upper clamping plate, and the lower end of the middle supporting sleeve is in threaded connection with an inner supporting rod with a cutting blade; a leakage-proof device is further arranged on the periphery of the outer supporting sleeve. The outer supporting sleeve, the middle supporting sleeve and the inner supporting rod are matched with one another, and clamping and cutting are achieved; the storage groove is matched with the cutting blade, so that the cutting blade is prevented from accidentally injuring human tissues, and the safety of the device is improved; the leakage-proof sliding sleeve and the elastic sealing sleeve made of materials with large elasticity are adopted to block the opening, the elastic sealing sleeve possibly changes elastically along with the size of the opening within a certain range, the leakage-proof sliding sleeve can be prevented from making direct contact with the opening to cause abrasion, the sealing effect can be enhanced, internal liquid is prevented from flowing out, and meanwhile external bacteria are prevented from entering the opening.

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...
