DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be apparently and completely described in connection with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor fall within the protection scope of the utility model.

[0022] As introduced in the background art, the deficiencies existing in the prior art, in order to solve the above technical problems, the present application provides a radiofrequency endoscope electrode coagulation cutter.

[0023] Please refer to Figures 1-5 Radiofrequency endoscope electrode coagulation cutter, including coagulation cutter main part 1 and the electrode coagulation cutting head 102 of the movable installation in the one side of coagulation cutter main part 1, the inside of the one side of coagulation cutter main part 1 has installation groove 101, the other side of electrode coagulation cutting head 102 is fixedly installed with the installation rod 103 located in the inside of installation groove 101, the top and bottom of installation groove 101 inner wall are provided with first sliding slot 104, the inside of first sliding slot 104 is slidably installed with the sliding bar 105 fixed to installation rod 103, and the other end of sliding bar 105 is provided with an opening, the outside of coagulation cutter main part 1 is sleeved with limit swivel ring 106, and the front end and the rear end of limit swivel ring 106 inner wall are provided with second sliding slot 107.

[0024] Through the above structural arrangement, when the electrode coagulation cutter of the radio frequency cavity mirror needs to replace the electrode coagulation cutting head 102 of different sizes to perform cutting hemostasis operation, first rotate the limiting rotating ring 106 to make the second sliding groove 107 in the vertical state, then install the mounting rod 103 on the other side of the electrode coagulation cutting head 102 of the specified size in the inside of the mounting groove 101, at this time, the sliding bar 105 slides into the inside of the first sliding groove 104, when the sliding bar 105 passes through the second sliding groove 107 to make the opening between the sliding bars 105 in the inside of the second sliding groove 107, then rotate the limiting rotating ring 106 to make the second sliding groove 107 in the horizontal state, thereby limiting and fixing the mounting rod 103, so that the electrode coagulation cutting head 102 is fixedly installed at one end of the coagulation cutter main body 1 to perform cutting hemostasis operation, which avoids that when the cutting wound is large and the caliber of the electrode coagulation cutting head 102 is small, the heat loss caused by the blood flow during the cutting process may cause the decline of the coagulation effect, which affects the hemostasis effect and cutting efficiency of the operation, thereby causing the situation that the cutting wound cannot be hemostasis in time and increases the difficulty of the operation.

[0025] Further, the inside of the mounting groove 101 is fixedly installed with an electrode block 108, and the electrode block 108 is electrically connected with the other end of the mounting rod 103. When the mounting rod 103 is installed in the inside of the mounting groove 101, the electrode sheet at the other end of the mounting rod 103 contacts with the electrode block 108, thereby electrifying the electrode coagulation cutting head 102, which facilitates the control of the electrode coagulation cutting head 102 to perform electric heating cutting hemostasis operation.

[0026] Further, the top of the coagulation cutter main body 1 is fixedly installed with a temperature display screen 109, and the temperature display screen 109 is electrically connected with the electrode coagulation cutting head 102 through a temperature sensor. When the electrode coagulation cutting head 102 is electrically heated to perform cutting hemostasis operation, the temperature of the electrode coagulation cutting head 102 is sensed through the temperature sensor (the model of the temperature sensor is NTC first sliding groove 104-F-3950, which is electrically connected with the temperature display screen 109, which is prior art in the field and will not be described here), and then displayed through the temperature display screen 109, which facilitates the control of the temperature of the electrode coagulation cutting head 102, and avoids that the temperature is too high or too low to affect the operation of the operation;

[0027] Further, the outer side of the electrode coagulation cutting head 102 is sleeved with the protective sleeve 2, the top and the bottom of one side of the coagulation cutter body 1 are provided with the first limiting groove 201, the first limiting groove 201 is movably provided with the limiting barb 202 fixed to the other side of the protective sleeve 2, the first limiting groove 201 is in through connection with the top and the bottom of the coagulation cutter body 1, and the other end of the limiting barb 202 is provided with an inclined surface. By sliding the limiting barb 202 into the first limiting groove 201, the protective sleeve 2 is sleeved with the electrode coagulation cutting head 102 for protection, so that the electrode coagulation cutting head 102 is prevented from falling on the ground or being damaged due to collision when not in use, and the limiting barb 202 is automatically slid into the first limiting groove 201 for limiting when sliding into the first limiting groove 201, so that the operation of the staff is facilitated, the limiting barb 202 is pressed inwards through the through hole in the top and the bottom of the coagulation cutter body 1, so that the limiting barb 202 is slid out of the 214, and the protective sleeve 2 is removed.

[0028] Further, the inside of one side of the coagulation cutter body 1 is provided with the cavity 3 located at the other side of the limiting rotating ring 106, the other side of the limiting rotating ring 106 is provided with the second limiting groove 301, the inside of the cavity 3 is movably provided with the limiting block 302 extending into the second limiting groove 301, and the inside of the cavity 3 is fixedly provided with the spring 303 fixedly connected with the limiting block 302. When the staff rotates the limiting rotating ring 106 to make the second sliding groove 107 in a horizontal state, the limiting block 302 is slid into the second limiting groove 301 for limiting under the elastic force of the spring 303, so that the limiting rotating ring 106 more stably limits and fixes the mounting rod 103, and one side of the limiting block 302 is a circular arc surface, so that the limiting rotating ring 106 can be automatically slid into or out of the second limiting groove 301 when rotating under external force.

[0029] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
