Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a ceramic buckle bipolar manipulator for an electro-resectoscope. Background Art

[0002] The bipolar manipulator of the electrosurgical endoscope is used in minimally invasive surgeries such as urology and gynecology. It is powered by a high-frequency generator and is used for high-frequency electrocautery surgery to image the surgical field, perform cutting, and perform electrocoagulation operations such as prostate hyperplasia resection or intrauterine diseased tissue resection.

[0003] Because the positive and negative electrodes of the bipolar electrodes in existing resection endoscopes are less than 1.5 mm apart, and each electrode has less than 0.1 mm of insulation, the insulation is easily damaged by friction during surgery, which can easily cause the metal clips of the two electrodes to connect with the positive and negative circuits and leak electricity. This can easily cause the bipolar operator to short-circuit or burn the valve body, resulting in a malfunction and the inability to perform the surgery properly. Utility Model Content

[0004] In order to solve the problems existing in the prior art, the utility model provides a ceramic buckle bipolar operator for electrocautery endoscope. The ceramic buckle has good insulation performance. Even if the insulation layers of the positive and negative poles of the bipolar electrode are damaged by friction during the operation, it will not cause the positive and negative pole circuits of the bipolar electrocautery to be connected and leak, and the problem of burning the electrodes of the bipolar operator will not occur.

[0005] In order to achieve the above purpose, the technical solution of the utility model is:

[0006] A ceramic buckle bipolar operator for an electro-resection endoscope comprises a ceramic buckle in a convex shape, which is installed in a concave hollow position reserved in the middle of a locking plate support, and the ceramic buckle and the locking plate support form a locking bracket.

[0007] Next, place the locking bracket in the groove of the electrode valve, then place the front cover on the front of the locking bracket. Then, insert four screws through the two screw holes on each side of the front cover, and then into the two screw holes on each side of the electrode valve for locking installation. At this point, the locking bracket, electrode valve, and front cover form an integral component, the valve body. The bipolar hole slot in the center of the electrode valve, the ceramic buckle in the center of the locking plate, and the bipolar through-hole in the center of the front cover are all coaxial, equidistant, and equidistant, ensuring that the bipolar electrodes of the bipolar resection endoscope can pass through smoothly and in sequence, and that the positive and negative ends of the bipolar electrodes can be locked by the ceramic buckle.

[0008] The ceramic buckle of the utility model is made of high-temperature resistant ceramic insulating material.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] Compared with the metal buckle in the bipolar operator of the existing electrosurgical endoscope, the ceramic buckle of this device has good insulation performance, which avoids the leakage of electricity between the metal buckles of the two poles and the positive and negative pole circuits when the insulation layers of the positive and negative poles of the existing bipolar electrodes are damaged by friction, thereby avoiding the possibility of short circuit of the bipolar operator or burning of the valve body; at the same time, the ceramic buckle of this device also has the characteristics of super wear resistance and high strength, which extends its service life.

[0019] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further explained below with reference to the accompanying drawings.

[0020] Example 1

[0021] See also Figures 1-6A ceramic buckle bipolar manipulator for an electrosurgical endoscope includes a ceramic buckle (111) as a "convex" body, the ceramic buckle (111) is installed in a concave hollow position reserved in the middle of a locking plate support (112), and the ceramic buckle (111) and the locking plate support (112) constitute a locking bracket (110). The locking bracket (110) is placed in the groove of the electrode valve (120), and then the front cover (130) is placed at the front end of the locking bracket (110). Then, four screws (131) are respectively passed through two screw through holes (132) on both sides of the front cover (130), and then reach two screw hole slots (121) on both sides of the electrode valve for locking installation. At this time, the locking bracket (110), the electrode valve (120) and the front cover (130) constitute an integral component as a valve body (100). Among them, the bipolar hole groove (122) in the middle of the electrode valve (120), the ceramic buckle (111) in the middle of the locking plate support (112) and the bipolar through hole (133) in the middle of the front cover (130) are all coaxial, equidistant and can ensure that the bipolar electrodes (200) of the bipolar resection endoscope can pass through smoothly in sequence, and the positive and negative pole tails of the bipolar electrode (200) can be locked by the ceramic buckle (111).

[0024] During high-frequency electrocautery surgery, the ceramic buckle in the ceramic buckle bipolar manipulator for the resectoscope has good insulation performance. Even if the insulation layers of the positive and negative poles of the bipolar electrode are damaged by friction, the ceramic buckles of the two poles will not cause leakage of the positive and negative pole circuits, and the bipolar manipulator will not short-circuit or burn the valve body, thereby ensuring normal operation.
