Referring to fig. 1, the right forceps piece 2 includes a hand-held portion 21 and a crane beak portion 22; the handheld part 21 is fixedly connected to the fixed seat 1 and extends out of the rear part of the fixed seat 1, and the part of the handheld part 21 extending out of the rear part of the fixed seat 1 is an electric connection part 23; the outer side surface of the handheld part 21 is provided with corrugated bulges so as to increase the hand feeling of holding. The crane beak part 22 is a slender metal sheet and is connected with the front part of the hand-held part 21, and the foremost end of the crane beak part 22 is a forceps tip part 24 for directly carrying out operation on human tissues; the forceps tip 24 may be straight, as shown in fig. 5, curved, as shown in fig. 6, or otherwise shaped to accommodate the needs of various surgical procedures.
The position of the left forceps piece 3 is opposite to that of the right forceps piece 2, and the shape of the left forceps piece 3 is symmetrically the same as that of the right forceps piece 2. Referring to fig. 2, the left forceps sheet 3 also includes a holding portion 31, a crane beak portion 32, a forceps tip portion 34 and an electrical connection portion 33.
The electric connection part 23 of the right forceps sheet 2 and the electric connection part 33 of the left forceps sheet 3 are conductive parts and are respectively connected with a socket and then connected into the high-frequency electrotome.
The middle support 4 is a cylinder with a circular arc-shaped head, is made of metal, and is fixedly connected (for example, welded) to the middle of the crane beak 22 of the right forceps piece 2 facing the inner side surface of the left forceps piece 3 to become a second supporting point of the special bipolar electrocoagulation forceps for transnasal saucer surgery except the fixed seat 1. The middle support 4 can also be fixedly connected with the middle part of the crane beak 32 of the left forceps piece 3 towards the inner side surface of the right forceps piece 2.
Referring to fig. 2, normally, the middle support 4 is not in contact with the left forceps piece 3, and the forceps tip 24 of the right forceps piece 2 is in an open state of being out of contact with the forceps tip 34 of the left forceps piece 3. When the hand-holding portion 21 and the hand-holding portion 32 are normally pinched, the right forceps piece 2 and the left forceps piece 3 are closed, the forceps tip portion 24 and the forceps tip portion 34 at the front end are closed, please refer to fig. 3, and at this time, the middle support 4 and the left forceps piece 3 are still in a non-contact state. Continue to hold between fingers and hold together handheld portion 21 and handheld portion 32, the right forceps piece 2 continues to be close to with left forceps piece 3, until middle pillar 4 with the contact of left forceps piece 3, later the tweezers point portion 24 and the tweezers point portion 34 of right forceps piece 2 and the 3 front ends of left forceps piece use this middle pillar 4 as the fulcrum, carry out the secondary once more and open to form a littleer electric coagulation forceps in bipolar electric coagulation forceps front portion, reduced and operated required space, satisfied the demand of intranasal dish operation, made things convenient for the operation.
The utility model requires special attention to the electrical insulation performance because of the personal safety of the operating doctor, the nurse and the patient.
The fixed seat 1 is insulated, and the distance between the right forceps piece 2 and the left forceps piece 3 meets the requirement of electrical distance; on the right and left forceps pieces 2 and 3, surfaces other than the electrical connection portions 23 and 33 and the forceps tip portions 24 and 34 are coated with an insulating coating 5, see fig. 5 and 6.
