Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of electrocoagulation hemostatic knives, and particularly relates to an anti-misoperation electrocoagulation hemostatic knife. Background Art
[0002] Conventional hemostatic electrocoagulation on the market all adopts push-button power supply for operation, which has potential safety hazards. When doctors hold it, they are very likely to accidentally press it, resulting in the head being powered on for operation, and there is a risk of accidentally injuring doctors or patients. Content of the Utility Model
[0003] The purpose of the utility model is to solve the defect of accidentally injuring doctors or patients in the prior art when using push-button power supply, and to propose an anti-misoperation electrocoagulation hemostatic knife. This anti-misoperation electrocoagulation hemostatic knife can avoid accidental injuries caused by misoperation and improve the safety of use.
[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0004]
[0005] Design an anti-misoperation electrocoagulation hemostatic knife, including a knife body handle. A fixed column is provided at the front end of the knife body handle. A positive conductive column and a negative conductive column are fixedly penetrated in the fixed column. A hemostatic knife body is fixedly connected to the same side of the positive conductive column and the negative conductive column. A battery is provided inside the knife body handle. Positive connection conductive sheets and negative connection seats are respectively provided at both ends of the battery. The end of the negative conductive column away from the hemostatic knife body is connected to the negative connection seat, and the end of the positive conductive column away from the hemostatic knife body is suspended inside the knife body handle; a chute is provided at the front end outside the knife body handle. A push slider is slidably connected in the chute. A sliding conductive sheet is connected to the bottom of the push slider. The sliding conductive sheet is slidably connected to the positive connection conductive sheet; a first conductive contact is provided at one end of the sliding conductive sheet located at the bottom of the push slider; a first indicator light is provided outside the knife body handle and at the front end of the chute. The positive and negative terminal posts of the first indicator light are respectively connected to the positive conductive column and the negative conductive column.
[0006] Further, a cover is provided at the end of the knife body handle away from the fixed column.
[0005]
[0007] Further, a limiting groove is provided inside the knife body handle and behind the chute. The sliding conductive sheet is slidably connected in the limiting groove, so that during the sliding process of the sliding conductive sheet, it always remains in contact with the positive connection conductive sheet.
[0008] Further, the first conductive contact is of a long sheet structure. When the push slider is pushed forward, the first conductive contact contacts the positive conductive column to form a circuit. When the push slider is pushed backward, the first conductive contact separates from the positive conductive column to form an open circuit.
[0006]
[0009] Furthermore, the first conductive contact piece is of a short piece structure. When the pushing slider is pushed forward, the first conductive contact piece is located above the positive conductive column. When the pushing slider is pressed, the first conductive contact piece comes into contact with the positive conductive column to form a circuit. When the pushing slider is released or pushed backward, the first conductive contact piece is separated from the positive conductive column to form an open circuit.
[0010] Furthermore, it further includes a second indicator light. The second indicator light is arranged behind the first indicator light. The negative terminal of the second indicator light is connected to the negative conductive column, and the positive wire column is in a suspended state. A second conductive contact piece is provided at the front end of the bottom of the sliding conductive piece where the pushing slider is located. When the pushing slider is pushed forward, the second conductive contact piece comes into contact with the positive wire column to form a circuit and light up the second indicator light. When the pushing slider is pressed, the second conductive contact piece is separated from the positive wire column to form an open circuit and the second indicator light goes out.
[0011] Compared with the prior art, the beneficial effects of using an anti-misoperation electrocoagulation hemostat proposed by the present utility model are as follows: The present utility model can avoid accidental injuries caused by misoperations and improve the safety of use.
[0012] (1) The present utility model changes the pressing type of the control switch to a forward-pushing type, which can effectively avoid accidental injuries to doctors or patients caused by accidental pressing and improve the safety of use.
[0013] (2) By adding an indicator light in the present utility model, when the electrocoagulation hemostat is in a working state, the indicator light at the head will light up, which plays a very good warning role and a prompting role for the user. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Now, in combination with the accompanying drawings of the specification, the structural features of the present utility model will be described in detail.
[0026] Embodiment 1
[0027] See Figures 1 - 3, An anti-misoperation electric coagulation hemostatic knife, comprising a knife body handle 1. A fixed column 2 is provided at the front end of the knife body handle 1. A positive conductive column 3 and a negative conductive column 4 are fixedly penetrated in the fixed column 2. The positive conductive column 3 and the negative conductive column 4 are of an integral structure with the fixed column 2, improving the stability of the positive conductive column 3 and the negative conductive column 4. A hemostatic knife body 5 is fixedly connected to the same side of the positive conductive column 3 and the negative conductive column 4. A battery 8 is provided inside the knife body handle 1, and the battery 8 is detachable and replaceable. In order to facilitate the replacement of the battery 8, a cover 11 is provided at the rear end of the knife body handle 1 for sealing the battery 8. Positive connection conductive sheets 81 and negative connection seats 82 are respectively provided at both ends of the battery 8. One end of the negative conductive column 4 far from the hemostatic knife body 5 is connected to the negative connection seat 82, and one end of the positive conductive column 3 far from the hemostatic knife body 5 is suspended inside the knife body handle 1.
[0028] A chute 12 is provided at the front end outside the knife body handle 1. A push slider 6 is slidably connected in the chute 12. A sliding conductive sheet 9 is connected to the bottom of the push slider 6. The sliding conductive sheet 9 is slidably connected to the positive connection conductive sheet 81. The sliding conductive sheet 9 can slide and adjust on the positive connection conductive sheet 81, and at the same time does not affect the electrical conduction between the two. In order to ensure good contact between the sliding conductive sheet 9 and the positive connection conductive sheet 81, a limiting groove 13 is provided inside the knife body handle 1 and behind the chute 12. The sliding conductive sheet 9 is slidably connected in the limiting groove 13, so that during the sliding process of the sliding conductive sheet 9, it always remains in contact with the positive connection conductive sheet 81. One end of the sliding conductive sheet 9 at the bottom of the push slider 6 is provided with a first conductive contact piece 91. Specifically, the first conductive contact piece 91 is of a long sheet structure. When the push slider 6 is pushed forward, the first conductive contact piece 91 contacts the positive conductive column 3 to form a circuit. At this time, the hemostatic knife body 5 is energized to work. When the push slider 6 is pushed backward, the first conductive contact piece 91 is separated from the positive conductive column 3 to form an open circuit, and the hemostatic knife body 5 is powered off and does not work.
[0029] A first indicator light 71 is provided outside the knife body handle 1 and at the front end of the chute 12. The first indicator light 71 can emit green light, yellow light or red light after being lit, having a good reminder effect. The positive and negative terminal posts of the first indicator light 71 are respectively connected to the positive conductive column 3 and the negative conductive column 4. When the push slider 6 is pushed forward and the first conductive contact piece 91 contacts the positive conductive column 3 to form a circuit, at this time the first indicator light 71 is energized and lit.
[0030] The anti-misoperation electric coagulation hemostatic knife of the present utility model adopts a forward-push type of work. On the one hand, it can effectively avoid accidental injuries to doctors or patients caused by accidental pressing, improving the safety of use. On the other hand, during the use process, by adding the first indicator light 71, when the hemostatic electric coagulation knife is in the working state, the indicator light at the head will light up, playing a very good warning role for the user and serving as a reminder.
[0031] Specifically, when in use, push the push slider 6 forward to make the first conductive contact piece 91 contact with the positive conductive column 3, forming a circuit. At this time, the first indicator light 71 is lit, and the hemostatic knife body 5 is powered on for operation. Push the push slider 6 backward to separate the first conductive contact piece 91 from the positive conductive column 3, forming an open circuit. The first indicator light 71 goes out, and the hemostatic knife body 5 is powered off.
[0032] Embodiment 2
[0033] Refer to Figures 4 - 6 , as another preferred embodiment of the present invention, different from Embodiment 1, the first conductive contact piece 91 is of a short film structure. When the push slider 6 is pushed forward, the first conductive contact piece 91 is located above the positive conductive column 3. Press the push slider 6, and the first conductive contact piece 91 contacts the positive conductive column 3, forming a circuit. When the push slider 6 is released or pushed backward, the first conductive contact piece 91 is separated from the positive conductive column 3, forming an open circuit. It further includes a second indicator light 72, which is arranged behind the first indicator light 71. The negative terminal of the second indicator light 72 is connected to the negative conductive column 4, and the positive wire column 73 is in a suspended state. A second conductive contact piece 92 is provided at the front end of the bottom of the push slider 6. When the push slider 6 is pushed forward, the second conductive contact piece 92 contacts the positive wire column 73, forming a circuit and lighting the second indicator light 72. Press the push slider 6, and the second conductive contact piece 92 is separated from the positive wire column 73, forming an open circuit, and the second indicator light 72 goes out. Specifically, when in use, push the push slider 6 forward so that the first conductive contact piece 91 is located above the positive conductive column 3 and does not contact the positive conductive column 3. At this time, the second conductive contact piece 92 contacts the positive wire column 73, lighting the second indicator light 72 to remind the user that the electrocoagulation hemostatic knife is in a pre-use state at this time. Then press down the push slider 6 to separate the second conductive contact piece 92 from the positive wire column 73, and the second indicator light 72 goes out. Make the first conductive contact piece 91 contact the positive conductive column 3, forming a circuit. At this time, the first indicator light 71 is lit, and the hemostatic knife body 5 is powered on for operation. When the push slider 6 is released, the electrocoagulation hemostatic knife is in a pre-use state again, or when the push slider 6 is pushed backward, the first conductive contact piece 91 is separated from the positive conductive column 3, forming an open circuit, and the hemostatic knife body 5 is powered off. Through the two-sided warning, the use safety of the electrocoagulation hemostatic knife can be further improved.
