DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0023] As introduced in the background, in order to solve the above technical problems, the present application provides a radio frequency endoscope electrode blood vessel forceps.

[0024] Please refer to Figures 1-5 , the radio frequency endoscope electrode blood vessel forceps comprises a first blood vessel handle 1 and a second blood vessel handle 101 rotatably installed at the top of the first blood vessel handle 1. The inside of one end of the first blood vessel handle 1 and the second blood vessel handle 101 is provided with a contraction cavity 102. The side of the first blood vessel handle 1 and the second blood vessel handle 101 away from each other is uniformly provided with a limiting hole 103. The inside of the contraction cavity 102 movably installs a telescopic rod 104. The other end of the telescopic rod 104 is provided with a cavity 105. The inside of the cavity 105 movably installs a limiting block 106 extending into the limiting hole 103. The outside of the limiting block 106 is an inclined surface. The inside of the cavity 105 fixedly installs a spring 107 fixedly connected with the limiting block 106.

[0025] Through the above structure, the radio frequency endoscope electrode blood vessel forceps is pulled outwardly to move the telescopic rod 104. Since one end of the limiting block 106 is an inclined surface, one end of the limiting block 106 is automatically moved into the limiting hole 103 on one side. The telescopic rod 104 is limited and fixed by the elastic force of the spring 107, so that the distance between the electrode blood vessel forceps head 110 and the rotating shaft joint is extended to a proper length. At this time, if the inner layer of the skin is needed to be cut, the rotating shaft joint will not extend into the skin layer, so as to avoid the blood caused by the error of the rotating shaft clamped to the tissue and skin layer during clamping, thereby increasing the difficulty of the operation. If the outer layer of the tissue is needed to be cut, the telescopic rod 104 is contracted into the contraction cavity 102, so as to make the electrode blood vessel forceps head 110 more convenient to force and cut the outer tissue mucosa.

[0026] Further, the inner side of the contraction cavity 102 is provided with a sliding groove 108, and a sliding block 109 fixedly connected with the telescopic rod 104 is slidably installed in the sliding groove 108. When the telescopic rod 104 slides in the contraction cavity 102, the sliding block 109 slides in the sliding groove 108, so that the telescopic rod 104 is prevented from sliding out of the contraction cavity 102, and the telescopic movement of the telescopic rod 104 is more stable.

[0027] Further, one end of the telescopic rod 104 is fixedly provided with an electrode blood vessel clamp head 110, and the inner side of the electrode blood vessel clamp head 110 is uniformly provided with a tooth groove 111. The electrode blood vessel clamp head 110 is inserted into the skin layer for operation, and the tooth groove 111 increases the friction with the tissue, so that the electrode blood vessel clamp head 110 is easier to operate when clamping.

[0028] Further, the other end of the first blood vessel clamp handle 1 and the second blood vessel clamp handle 101 is fixedly provided with a ring 2, the other side of the rear end ring 2 is fixedly provided with a finger rod 201, and the inner side of the other side of the first blood vessel clamp handle 1 and the second blood vessel clamp handle 101 is fixedly provided with a stabilizing block 4. The first blood vessel clamp handle 1 and the second blood vessel clamp handle 101 are held by the ring 2 for operation, and then the ring finger or the little finger is in contact with the finger rod 201 to provide a force, so that the medical staff can operate more conveniently. When the first blood vessel clamp handle 1 and the second blood vessel clamp handle 101 are closed, the two stabilizing blocks 4 are in contact with each other, so that the first blood vessel clamp handle 1 and the second blood vessel clamp handle 101 are prevented from shaking when being rotated and closed, thereby affecting the operation of the medical staff;

[0029] Further, the other side of the top of the second blood vessel clamp handle 101 is rotatably provided with a positioning plate 3, the other side of the front end of the positioning plate 3 is provided with a positioning groove 301, and the other side of the top of the first blood vessel clamp handle 1 is fixedly provided with a fixed rod 302 extending into the positioning groove 301. When the blood vessel clamp is not used, the first blood vessel clamp handle 1 and the second blood vessel clamp handle 101 are rotated and closed, and then the positioning plate 3 is rotated to make the fixed rod 302 slide into the inside of the positioning groove 301 for limiting and fixing, so that the first blood vessel clamp handle 1 and the second blood vessel clamp handle 101 are fixedly closed, the blood vessel clamp is convenient to carry, and the first blood vessel clamp handle 1 and the second blood vessel clamp handle 101 are prevented from being automatically opened during carrying, so as to avoid damage;

[0030] Further, the top of the second blood vessel clamp handle 101 is fixedly provided with a first magnetic block 303, and one side of the bottom of the positioning plate 3 is fixedly provided with a second magnetic block 304 matched with the first magnetic block 303. When the medical staff uses the blood vessel clamp, the positioning plate 3 is turned to one side of the second blood vessel clamp handle 101, and at this time, the positioning plate 3 is fixed on the top of the second blood vessel clamp handle 101 due to the magnetic attraction between the first magnetic block 303 and the second magnetic block 304, so that the shaking of the positioning plate 3 during use does not affect the operation of the medical staff;

[0031] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
