[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0032] Referring to Figure 1 - Figure 2 , an embodiment provided by the present utility model: A novel electric cutting device for prostate enucleation includes a connecting rod 1. The left end of the connecting rod 1 is fixedly connected with the neck 3 of the electric cutting ring. The neck 3 of the electric cutting ring is thickened and reinforced to prevent the neck 3 of the electric cutting ring from being distorted and deformed due to excessive force during the peeling operation. The left end of the neck 3 of the electric cutting ring is fixedly connected with a ceramic plate 4. Through the ceramic plate 4, actions such as lifting and peeling and swinging in all directions can be performed during the prostate enucleation operation, and then cooperating with the electric cutting handle to perform a depth pushing action to achieve the purpose of peeling the prostate along the prostate capsule layer. The left end of the ceramic plate 4 is fixedly connected with an electric cutting head 5. The electric cutting head 5 is embedded in the ceramic plate 4 and is used for electric cutting of prostate tissue, electrocoagulation hemostasis, etc. The top of the connecting rod 1 is fixedly connected with a connecting pipe 6. By inserting the electric cutting mirror into the connecting pipe 6, the electric cutting mirror can be installed on the electric cutting device. The right bottom end of the connecting rod 1 is hinged with a folding rod 2. The folding rod 2 and the connecting rod 1 form the main body tail of the electric cutting device. A folding assembly 7 is arranged on the connecting rod 1. Through the folding assembly 7, it is convenient to fold or unfold the connecting rod 1 and the folding rod 2.
[0033] Referring to Figure 2and Figure 3 The folding assembly 7 includes a hinge rod 71. Through the movement effect of the hinge rod 71, the round block 72 is driven to move. The left end of the hinge rod 71 is hinged with the round block 72. Through the movement effect of the round block 72, the slider 73 is driven to slide horizontally. The left side of the round block 72 is fixedly connected with the slider 73. By limiting the slider 73, the folding rod 2 is kept fixed. A chute 76 is opened on the right side of the connecting rod 1. There are two groups of connecting pipes 6. The two groups of connecting pipes 6 are horizontally arranged in an array along the top of the connecting rod 1. By providing two groups of connecting pipes 6, the electric endoscope can be stably installed on the connecting rod 1.
[0034] Refer to Figure 2 and Figure 4 The right end of the hinge rod 71 is hinged with the left side of the folding rod 2. Through the rotation effect of the folding rod 2, the hinge rod 71 is driven to move. The slider 73 is slidably connected to the inner wall of the chute 76. The front inner wall of the slider 73 is elastically connected with a latch 75 through a spring 74. Through the elastic force of the spring 74, the latch 75 is always kept engaged with the card slot 77 without external force, so as to limit the slider 73. A card slot 77 is opened on the front of the connecting rod 1.
[0035] Refer to Figure 3 and Figure 4 The shape of the slider 73 is circular, and the diameter dimension of the slider 73 is larger than the diameter dimension of the round block 72. By setting the size of the slider 73 to be larger than the size of the round block 72, the slider 73 can only slide along the inner wall of the chute 76, avoiding the slider 73 from falling off. One end of the spring 74 is fixedly connected to the front inner wall of the slider 73, and the other end of the spring 74 is fixedly connected to the outer wall of the latch 75. Through the fixing effect of the spring 74, the latch 75 is kept fixed, preventing the latch 75 from falling off.
[0036] Refer to Figure 2 Figure 4 There are two groups of card slots 77. The two groups of card slots 77 are horizontally arranged in an array along the front of the connecting rod 1. By providing two groups of card slots 77, the two groups of card slots 77 can be engaged with the latch 75 at different positions, so as to limit the slider 73 at different positions. One end of the latch 75 is slidably connected to the front inner wall of the slider 73. Through the sliding effect of the latch 75, the latch 75 is engaged with or disengaged from the card slot 77. The outer wall of the latch 75 is engaged with the inner wall of the card slot 77. Through the engagement effect of the latch 75 and the card slot 77, the connecting rod 1 limits the slider 73.
[0037] Working principle: When medical staff needs to use the electrocision device to perform surgery on a patient, by pressing the clamping block 75 by the staff, the clamping effect between the clamping block 75 and the clamping groove 77 is released, and at the same time, the limiting effect on the sliding block 73 is released. Subsequently, the folding rod 2 is flipped to the right, so that the folding rod 2 and the connecting rod 1 are on the same horizontal line. During the rotation of the folding rod 2, the articulated rod 71 is driven to move. The round block 72 is driven by the articulated rod 71 to move to the left, so that the sliding block 73 slides to the left along the inner wall of the sliding groove 76, thereby driving the clamping block 75 to move to the left. Under the elastic force of the spring 74, the clamping block 75 is clamped with the clamping groove 77 near the left side on the connecting rod 1, and at the same time, the sliding block 73 is limited, so that the folding rod 2 is fixed and is on the same horizontal plane as the connecting rod 1.
[0038] Subsequently, the medical staff inserts and installs the electroscope into the two connecting pipes 6, and then inserts the electrocision knife head 5 into the surgical site of the patient to perform an enucleation operation. During the operation, the electrocision knife head 5 is used to electrosect the prostate tissue and electrocoagulate the bleeding. After electrosecting to the level of the prostate surgical capsule, the ceramic plate 4 is used to perform actions such as prying and swinging in all directions, and then cooperate with the electrocision handle to perform a depth pushing action to achieve the purpose of peeling the prostate along the prostate capsule level.
[0039] When the operation is completed and the electrocision device needs to be stored, by pressing the clamping block 75 by the staff, the fixing effect on the folding rod 2 is released, and the folding rod 2 is rotated downward to be folded with the connecting rod 1, so that the sliding block 73 slides to the right, thereby driving the clamping block 75 to be clamped with the clamping groove 77 near the right side on the connecting rod 1, and at the same time, the sliding block 73 is fixed, so that the folding rod 2 always maintains a folded state with the connecting rod 1, which is convenient for the staff to store.
[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
