Description

Technical Field

[0001] The utility model relates to the field of electrocoagulation forceps, in particular to a bipolar electrocoagulation forceps for surgical wound hemostasis. Background Art

[0002] Minimally invasive surgery is the development direction of current surgical operations. Minimally invasive surgery often requires electrocoagulation hemostasis treatment for small blood vessels and small wounds. Nowadays, in bipolar electrocoagulation hemostasis, two electrodes are respectively installed on two blades of a pair of forceps, and the space between the two blades of the forceps is insulated. During application, the current only passes through the tissue between the two forceps tips. Compared with the previous monopolar electrocoagulation hemostasis, the ineffective electrode in contact with the patient's buttocks is eliminated, and the required electric quantity is greatly reduced.

[0003] According to the disclosed patent CN215130015U, for a bipolar electrocoagulation forceps for surgical wound hemostasis, when the driving member is pushed forward or backward, the driving member drives the intermediate layer tube to perform a piston movement, and the bifurcated electrode forceps at the tail end of the electrode inner tube are pressed by the intermediate layer tube to be combined or released.

[0004] In the process of implementing the present utility model, the inventor found that at least the following problems in the prior art have not been solved. When using the electrocoagulation forceps for surgical wound hemostasis, it is necessary for the staff to push the driving member to make the bifurcated electrode forceps combined for surgical wound hemostasis. However, during the use process, it is necessary for the staff to continuously push the driving member to ensure that the bifurcated electrode forceps are continuously combined for surgical wound hemostasis. Therefore, a new technical solution needs to be designed to solve this problem. Content of the Utility Model

[0005] The purpose of the present utility model is to overcome the deficiencies of the prior art, adapt to the actual needs, and provide a bipolar electrocoagulation forceps for surgical wound hemostasis, so as to solve the technical problem that the current bipolar electrocoagulation forceps need to be continuously pressed by the staff to perform surgical wound hemostasis.

[0006] To achieve the purpose of the present utility model, the technical solution adopted by the present utility model is as follows: Design a bipolar electrocoagulation forceps for surgical wound hemostasis, including forceps bodies. The number of the forceps bodies is two groups, and the two groups of forceps bodies are symmetrically arranged. One end of the forceps body handle is provided with an electrode wire, and a forceps head is detachably installed at the end of the forceps body far from the handle. It also includes a connecting block; an adjusting mechanism: used for the combination of the forceps heads at one end of the two groups of forceps bodies. The adjusting mechanism includes a first adjusting rod, a second adjusting rod and a spring. Rotating grooves are symmetrically opened on the front and back sides of the connecting block. The bent part of the forceps body close to the handle penetrates and is fixedly installed with a connecting rod. Both ends of the connecting rod are rotationally connected to the inner walls of the top and bottom of the rotating groove. The first adjusting rod is fixedly connected to the handle of the upper forceps body, the second adjusting rod is fixedly connected to the handle of the lower forceps body, a limiting groove is opened inside the second adjusting rod, the first adjusting rod is slidably connected with the limiting groove, and the spring is placed inside the limiting groove.

[0007] Preferably, an installation groove is opened at the end of the forceps body far from the handle. One end of the forceps head is fixedly connected with a conductive joint, and the conductive joint is threadedly connected with the installation groove.

[0008] Preferably, a conductive rod is arranged inside the forceps body. One end of the conductive joint is movably connected with one end of the conductive rod placed inside the installation groove, and the other end of the conductive rod is fixedly connected with the electrode wire.

[0009] Preferably, a limiting block is slidably connected inside the limiting groove, and one end of the first adjusting rod placed inside the limiting groove is fixedly connected with the limiting block.

[0010] Preferably, both ends of the spring are fixedly connected with the bottom side of the limiting block and the inner wall of the bottom end of the limiting groove respectively, and the spring is matched with the size of the limiting groove.

[0011] Preferably, the first adjusting rod and the second adjusting rod are matched in size, and the first adjusting rod and the second adjusting rod are arc-shaped.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. The forceps body of the present utility model is rotationally connected with the rotating groove opened on the outside of the connecting block through the connecting rod, and the first adjusting rod is slidably connected with the limiting groove inside the second adjusting rod. When the handle is no longer pressed, the elastic force of the spring inside the limiting groove can push the handles of the two groups of forceps bodies to move in the opposite direction and open. At the same time, the forceps heads at one end of the forceps bodies move relatively and automatically clamp small blood vessels or small wounds, thus solving the problem that the existing bipolar electrocoagulation forceps need the staff to continuously press the forceps body to make the forceps heads of the electrocoagulation forceps clamp small blood vessels or small wounds for surgical wound hemostasis, and reducing the labor intensity of medical staff.
