Embodiment Construction

[0013] Embodiments of the present invention are described in detail below. On the basis of the technical solution of the present invention, the present embodiment provides detailed implementation and specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0014] Such as figure 1 As shown, this embodiment includes: a first tong arm 1, a second tong arm 2, a pin shaft 3 and a push-pull rod 4, wherein: the pin shaft 3 is connected to the push-pull rod 4, and the first tong arm 1 and the second tong arm 2 are connected to each other with bearing pin 3 activities respectively. When force acts on the push-pull rod 4, the push-pull rod 4 makes the two pliers arms open and close by the pin shaft 3.

[0015] Such as figure 2 and image 3 As shown, the end of the first pliers arm 1 is provided with a first chute 5, the end of the second pliers arm 2 is provided with a second chute 6, and the first chute 5 and the s...

Abstract

The invention provides a minimally invasive surgery (MIS) forceps head, and belongs to the technical field of MIS medical devices. The MIS forceps head comprises a first forceps arm, a second forceps arm, a pin shaft and a push-pull rod, wherein, the pin shaft is connected with the push-pull rod; a first chute is arranged on the tail end of the first forceps arm; a second chute is arranged on the tail end of the second forceps arm; and the first chute and the second chute are respectively connected with the pin shaft in a sheathed mode. By utilizing the MIS forceps head, a clamping force is in linear relationship with an operating force so that a surgeon can effectively control the clamping force.

Description

technical field [0001] The invention relates to a device in the technical field of minimally invasive medical surgical instruments, in particular to a minimally invasive surgical forceps head. Background technique [0002] Surgical forceps are a very common clinical surgical instrument. There is a linear relationship between the clamping force of the surgical forceps used in open surgery and the operating force, so it is easier for the operator to control the clamping force. However, there are defects in the design of the pincer head structure of the minimally invasive surgical forceps at present. That is, there is a non-linear relationship between the clamping force of the forceps head and the operating force, which makes it difficult for the operator to perceive and control the magnitude of the clamping force, which easily causes damage to the tissue and directly affects the success rate of the operation. In the rapidly developing minimally invasive surgery, this problem ...
