[0002] The electrocoagulation cutter generates heat energy through high-frequency current to achieve the purposes of cutting and hemostasis. It can quickly and effectively cut tissues during surgery, and at the same time reduce the risk of postoperative bleeding through the coagulation and hemostasis functions. According to different surgical needs, electrocoagulation cutters can be divided into different types, and a disposable electrocoagulation cutter with convenient operation is an important part among them;

[0003] For this reason, the patent with the publication number CN217118575U discloses a disposable multi-functional electrocoagulation cutter, which includes a grip structure. A lower fixed seat structure is installed on the grip structure, an upper fixed seat structure is installed at the upper end of the lower fixed seat structure, two connecting arm structures are symmetrically installed at the lower end of the upper fixed seat structure, and a clamping spring is arranged inside each of the two connecting arm structures. The disposable multi-functional electrocoagulation cutter described in the utility model belongs to the field of medical equipment. By setting the lower fixed seat structure and the upper fixed seat structure and making them cooperate with each other, it is convenient to fix the disposable multi-functional electrocoagulation cutter on the operator's finger, thereby avoiding the probability of the disposable multi-functional electrocoagulation cutter accidentally falling from the operator's hand during use; by setting the clamping spring, the lower fixed seat structure and the upper fixed seat structure can be made to approach each other, so that the lower fixed seat structure and the upper fixed seat structure can be firmly fixed on the operator's finger;

[0004] The above-mentioned disposable multi-functional electrocoagulation cutter can be conveniently fixed on the operator's finger during use, thereby avoiding the probability of the disposable multi-functional electrocoagulation cutter accidentally falling from the operator's hand during use. However, when in use, it needs to be connected to a wire, but it is inconvenient to prevent the wire from falling off, resulting in the wire being prone to looseness and poor contact, making its applicability low during use. Content of the Utility Model

[0005] The purpose of the utility model is to provide a disposable electrocoagulation cutter with convenient operation to solve the defect that the wire of the existing disposable electrocoagulation cutter with convenient operation is inconvenient to prevent from falling off.

[0015] Preferably, the inner side wall of the first fixing disk is fixedly connected to the outer side wall of the handle, and the clamping block and the first fixing disk form a clamping structure through the clamping groove. Thus, the second fixing disk and the first fixing disk are fixed to each other, strengthening the connection between the wire and the handle and preventing loosening at the connection between the wire and the handle during operation.

[0016] Preferably, one end of the clamping block extends to the outside of the first fixing disk and is fixedly connected to one side of the second fixing disk, and an anti-slip layer is provided on the outside of the second fixing disk. By providing the anti-slip layer on the outside of the second fixing disk, it is convenient to pull the second fixing disk to separate it from the first fixing disk.

[0017] An easy-to-operate disposable electrocoagulation cutter provided by the present utility model has the following advantages:

[0018] By providing a fixing structure, the wire is moved to one end of the handle. The wire drives the second fixing disk to move to one side of the first fixing disk. One end of the wire is moved into the handle. Under the action of the reserved groove, the second fixing disk drives the clamping block to move into the clamping groove, so that the second fixing disk and the first fixing disk are fixed to each other, strengthening the connection between the wire and the handle and preventing loosening at the connection between the wire and the handle during operation. By providing the anti-slip layer on the outside of the second fixing disk, it is convenient to pull the second fixing disk to separate it from the first fixing disk, realizing the function of the device being easy to prevent detachment, thereby improving the applicability of the easy-to-operate disposable electrocoagulation cutter during use;

[0019] By providing an anti-slip structure, the rubber sleeve is sleeved on the outside of the handle, making the rubber ring move into the limiting groove to prevent the rubber sleeve from shifting on the outside of the handle. At the same time, it can be taken off and reused. Under the action of the rubber sleeve, the contact area between the palm and the handle is increased. Under the action of the protective convex block, the friction between the palm and the rubber sleeve is increased to prevent the handle from slipping out of the hand. By providing an anti-adhesion coating on the outside of the cutting blade head, tissue adhesion during the operation can be effectively reduced, realizing the function of the device being easy to hold, thereby improving the convenience of the easy-to-operate disposable electrocoagulation cutter during use.
