Description

Technical Field

[0001] The utility model relates to a ceramic seat, in particular to a positionable ceramic seat used in ablation surgery. Background Art

[0002] The surgical electrode is an application part of a high-frequency electrosurgical minimally invasive surgical treatment device. It is an instrument that outputs energy to perform various treatments, including ablation, hemostasis, coagulation, vaporization, cutting and other surgical functions, and can perform surgical treatments on various parts and tissues, especially in ablation surgery; the current plasma surgical electrodes can perform basic surgical treatments. With the further development of minimally invasive surgery, the requirements for plasma surgical electrodes are also constantly increasing. Therefore, the development of new plasma surgical electrodes is a need of surgical clinical practice and an inevitable development trend; among them, the plasma blade used in low-temperature plasma ablation has integrated cutting, hemostasis, water intake and suction functions, which greatly saves the time occupied by frequent replacement of surgical instruments. The plasma blade relies on the stability of the plasma generated at one end of the blade emitter during the cutting process. This factor mainly depends on the uniform distribution of physiological saline at the blade.

[0003] The water outlets in existing products are all designed with single-side points. By opening several water outlets on one side, saline solution spreads from the single-side water outlet to the blade. However, this method still makes it difficult to keep the saline solution evenly wrapped around the electrode blade. At the same time, it is dependent on the speed at which the saline solution enters the body, which causes inconvenience to the operator and has great limitations in use. Utility Model Content

[0004] The main purpose of the present disclosure is to provide a positionable ceramic seat for use in ablation surgery, so as to effectively solve the problems raised by the inventor in the above background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the present utility model is as follows:

[0006] A positionable ceramic seat used in ablation surgery includes a ceramic seat body and a circular slice. A first electrode hole is provided at the center of the ceramic seat body. A plurality of liquid suction holes distributed in a circular array are provided in the ceramic seat body, and the first electrode hole is located in the middle of each liquid suction hole. An embedding opening is provided at the top of the ceramic seat body, and the circular slice is installed in the embedding opening. A second electrode hole is provided at the center of the circular slice, and a plurality of liquid outlet holes distributed in a circular array are provided on the circular slice. The first electrode hole and the second electrode hole are coaxially arranged, and each of the liquid suction holes is aligned with each liquid outlet hole.

[0007] Preferably, the side wall of the embedding is provided with a plurality of notched grooves distributed in a circular array, the bottom of each notched groove is fixedly connected to a reset spring, and the other end of the reset spring is fixedly connected to a water channel head, the water channel head is slidably connected to the top of the circular slice, and the bottom of the circular slice is tightly against the inner bottom wall of the embedding.

[0008] Preferably, the size of the water channel head is larger than the size of the liquid outlet hole, and the size of the liquid outlet hole is the same as the size of the liquid suction hole.

[0009] Preferably, a plurality of transparent holes distributed in a circular array are opened on the outer side of the ceramic seat body, and each transparent hole leads to each notch groove respectively. A propulsion rotating rod is movably passed through the transparent hole, one end of the propulsion rotating rod passes through the reset spring and is rotatably connected to the water channel head, and the other end of the propulsion rotating rod is fixedly connected to the operating block.

[0010] Preferably, L-shaped limiting frames distributed in a ring array are fixedly connected to the outer side of the ceramic seat body, and the curved ends of the L-shaped limiting frames extend downward.

[0011] Preferably, a positioning tube seat is fixedly connected to the bottom of the ceramic seat body, and the first electrode hole and the plurality of liquid suction holes all pass through the positioning tube seat.

[0012] In view of this, compared with the prior art, the beneficial effects of the present invention are:

[0013] (1) In the present application, the positioning tube seat at the lower end of the ceramic seat body is used to position and install the ceramic seat. The first electrode hole passing through it is used for the layout of the electrode. The liquid suction hole is connected to the liquid outlet hole to form a liquid injection channel to assist in the completion of the ablation operation and enable the liquid to flow more evenly to the blade.

[0014] (2) In the present application, the number of openings of the liquid outlets can be opened according to demand. When the number of openings of the liquid outlets is increased, the operating block is rotated so that the L-shaped limiting frame releases the limit on the operating block. Under the elastic force of the reset spring, the push rod drives the water channel head to move toward the notch groove, and then the water channel head releases the blockage of the liquid outlets. Similarly, when the number of openings of the liquid outlets is reduced, the operating block is pressed so that the push rod drives the water channel head to move above the liquid outlets, and then the operating block is rotated so that the L-shaped limiting frame blocks the operating block, and the reset spring is stretched, which greatly reduces the limitations of the use of the ceramic seat in ablation surgery.

[0025] Specifically, the side wall of the embedding is provided with a number of notched grooves 5 distributed in a circular array, the bottom of each notched groove 5 is fixedly connected to a reset spring 6, and the other end of the reset spring 6 is fixedly connected to a water channel head 4, the water channel head 4 is slidably connected to the top of the circular slice 3, and the bottom of the circular slice 3 is close to the inner bottom wall of the embedding, the size of the water channel head 4 is larger than the size of the liquid outlet 302, and the size of the liquid outlet 302 is the same as the size of the liquid suction hole 102.

[0026] Specifically, the outer side of the ceramic seat body 1 is provided with a number of transparent holes 103 distributed in a circular array, and each transparent hole 103 leads to each notch groove 5 respectively. A propulsion rotating rod 7 is movably passed through the transparent hole 103. One end of the propulsion rotating rod 7 passes through the reset spring 6 and is rotatably connected to the waterway head 4, and the other end of the propulsion rotating rod 7 is fixedly connected to the operating block 8. The outer side of the ceramic seat body 1 is fixedly connected to an L-shaped limiting frame 9 distributed in a circular array, and the curved end of the L-shaped limiting frame 9 extends downward.

[0027] Specifically, the bottom of the ceramic seat body 1 is fixedly connected to a positioning tube seat 2 , the first electrode hole 101 and the plurality of liquid suction holes 102 all pass through the positioning tube seat 2 , and the positioning tube seat 2 is used to install the ceramic seat.
