Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and more specifically, the utility model relates to a bipolar electrocoagulator with a replaceable forceps tip. Background Art

[0002] It is known that bipolar electrocoagulation is the basis of microsurgery, which can accurately burn small blood vessels and minimize the damage to adjacent tissues. It is one of the most important surgical instruments in neurosurgery and is used in almost every craniocerebral or spinal cord surgery. Among them, there are many models and types of bipolar electrocoagulation forceps available in clinical practice, all of which are integrated straight forceps tip bipolar electrocoagulation. Neurosurgical operations require delicate microsurgical operations, comfortable hand feeling, and involve different operating depths, different operating angles, and different operating precisions. Currently, a straight forceps tip bipolar electrocoagulation cannot fully meet the needs of a complex neurosurgical operation. Therefore, when performing surgery on special parts, in order to meet the surgical needs, the surgeon will use a needle holder to bend the forceps tip of the bipolar electrocoagulation forceps into the desired angle.

[0003] However, in actual use, if the forceps tip of the bipolar electrocoagulation forceps is bent, on the one hand, it is very difficult to make the angles of the two forceps tips the same, and then the forceps tips are misaligned during operation, resulting in poor coagulation effect and affecting the use. On the other hand, the forceps tip is easily broken and cannot be used, and the entire bipolar electrocoagulation forceps needs to be replaced, increasing the cost. Therefore, a bipolar electrocoagulator with a replaceable forceps tip is proposed as a further improvement to play a more comprehensive "grasping, separating, and coagulating" role in neurosurgical operations. Summary of the Utility Model

[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides a bipolar electrocoagulator with a replaceable forceps tip to solve the problems raised in the above background art.

[0005] To achieve the above object, the utility model provides the following technical solution: A bipolar electrocoagulator with a replaceable forceps tip, the bipolar electrocoagulator comprising: a double-lobe forceps body handle and forceps tips of various models;

[0006] The forceps tip comprises: a connecting rod and a forceps tip, one end of the connecting rod is fixedly connected to the forceps tip;

[0007] The end of the connecting rod away from the forceps tip is inserted into the end of the double-lobe forceps body handle, and the surface of the connecting rod inserted into the double-lobe forceps body handle contacts the inner wall of the double-lobe forceps body handle; the end of the double-lobe forceps body handle away from the forceps tip is fixedly connected to an electrode wire;

[0008] The surface of the connecting rod near the forceps tip, the outer surface of the double-lobe forceps body handle, and the outer surface of the electrode wire are all wrapped with an insulating layer;

[0009] The materials of the double-lobe forceps body handle, the connecting rod, and the forceps tip are all set as metal conductive materials.

[0010] Further, the minimum diameter of the forceps tip is less than 1 mm; the length of the forceps tip is set within the range of 5 - 10 mm.
