Description

Technical Field

[0001] The invention relates to the field of medical electrosurgery, in particular to a pair of labor-saving anti-dislocation electrocoagulation forceps. Background Art

[0002] The structure of ordinary bipolar coagulation forceps used in electrosurgery mostly adopts a structure in which two tweezers are fixed to the tail joint. Its structure is simple, but there are two defects. First, after a long period of pinching during the operation, the doctor is very likely to feel fatigued because the torque of the pinching force is shorter than the clamping force torque at the front end of the tweezers tip, so a greater force is required to ensure the clamping effect; second, the structural stability of these two tweezers is poor, and it is easy to cause the tweezers tip to be misaligned. Although there are coagulation forceps with positioning columns on the market, the positioning columns are mostly located at the rear end and cannot fully guarantee the fit of the front end tweezers tip. In particular, when the front end of the tweezers body is disturbed by external force, it is still easy to cause misalignment. Summary of the Invention

[0003] The invention aims to provide an anti-dislocation electrocoagulation forceps with labor-saving kneading, which can improve the kneading effect and stability of the entire electrocoagulation forceps.

[0004] The technical solution adopted by the present invention to solve its technical problems is to propose a pair of anti-dislocation electric coagulation tweezers that saves effort in pinching, including: a front tweezers blade, a tweezers handle movably connected to one end of the front tweezers blade, a tweezers blade, and a tail connecting head. The tweezers blade and the tweezers handle are both fixedly connected to the tail connecting head. The front tweezers blade is movably connected to the tweezers blade through a rotating shaft that passes through the front tweezers blade and the tweezers blade, so that the front tweezers blade can rotate relative to the tweezers blade with the rotating shaft as the base point.

[0005] Furthermore, the tail connector is not fixed with the tweezers blades, but is fixed with a connecting portion at one end of the tweezers handle.

[0006] Furthermore, a movable channel is provided in the tweezers handle, and connecting rods are extended on both sides of the end of the front tweezers away from the rotating shaft. The ends of the two connecting rods away from the rotating shaft are connected by a connecting shaft, and the front tweezers, connecting rods and connecting shafts enclose a movable space. The connecting shaft passes through the movable channel and can reciprocate in the movable channel.

[0007] Furthermore, the tweezers handle is provided with anti-slip grooves.

[0008] Furthermore, the rotating shaft includes a shaft body and fixed heads fixed to both ends of the shaft body.

[0009] Furthermore, an insulating plate is provided between the front tweezers and the tweezers, and the insulating plate is penetrated by the rotating shaft.

[0010] Furthermore, the front tweezers, the tweezers, and the insulating plate are all provided with through holes of the same size for the rotation shaft to pass through.

[0011] Furthermore, the tweezers handle and the tweezers blades are both provided with a snap-on component at one end close to the tail connector.

[0012] Furthermore, the width of the end of the clip away from the tail connector is smaller than the width of the tweezers, and the width of the end of the clip close to the tail connector is equal to the width of the tweezers.

[0013] The beneficial effects of the present invention are: 1. It has a labor-saving structure. Compared with ordinary electrocoagulation forceps on the market, the torque of its pinching force is longer, so it is more labor-saving. When the same clamping force is applied to the tissue, the pinching force required is smaller, which helps to relieve the doctor's fatigue during surgery. 2. Through the setting of the front tweezers and the tweezers handle, the device structure conforms to ergonomic design and is more suitable for pinching operations. 3. The movable connection between the front tweezers and the tweezers makes it more stable than ordinary electrocoagulation forceps on the market. Even if the pinching force during pinching deviates from the direction of the tweezers body, the front tweezers tip will not be misplaced, thereby ensuring the accuracy of the surgical operation.

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. It should be noted that, in the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other in any way.

[0022] Example 1

[0023] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 The present invention provides an anti-dislocation electric coagulation tweezers with labor-saving kneading, comprising: a front tweezers blade 1, a tweezers handle 2 movably connected to one end of the front tweezers blade 1, a tweezers blade 3, and a tail connector 4. The tweezers blade 3 and the tweezers handle 2 are both fixedly connected to the tail connector 4. The front tweezers blade 1 is movably connected to the tweezers blade 3 through a rotating shaft 5 that passes through the front tweezers blade 1 and the tweezers blade 3, so that the front tweezers blade 1 can rotate relative to the tweezers blade 3 with the rotating shaft 5 as a base point.

[0024] The non-stick material of the tweezers tip at the front end of the front tweezers 1 and tweezers 3 can be selected from silver-based alloys, copper-based alloys, gold-based alloys, etc. The device is composed of a labor-saving structure consisting of the front tweezers 1, the tweezers handle 2, and the tweezers 3. Compared with ordinary electrocoagulation tweezers on the market, the torque of its pinching force is longer, so it is more labor-saving. When applying the same clamping force to the tissue, the pinching force required is smaller, which helps to relieve the doctor's fatigue during surgery. The specific principle is as follows Figure 4 、 5 As shown, Figure 5 This is a schematic diagram of the force structure of ordinary electrocoagulation forceps on the market. When using ordinary electrocoagulation forceps, medical staff generally use their thumbs to apply force to the middle part of the forceps blade 3 near the tip of the forceps. Since the support axis is at the tail connector 4, the torque corresponding to the force applied by the thumb is smaller than the torque corresponding to the clamping force formed at the tip of the forceps. Therefore, the clamping force applied by the tip of the forceps on the tissue is smaller than the pinching force applied by the thumb, resulting in the need to apply a greater force at the thumb to achieve the clamping force expected by the medical staff. This is also the reason why it is more laborious. When medical staff perform surgery for a long time, the more laborious process will cause stiffness and soreness in the hand muscles, affecting the effect of the later stage of the surgery. The force applied by this device is as follows: Figure 4As shown, through the structural setting of the present device, the fulcrum is changed from the tail connector 4 to the rotating shaft 5, and the position where the thumb of the medical staff applies force is the end of the forceps handle 2 away from the tail connector 4, which makes the torque corresponding to the pinching force applied by the thumb greater than the torque corresponding to the clamping force formed by the tip of the forceps, so the clamping force applied to the tissue will be greater than the pinching force of the thumb, that is, it allows medical staff to apply force and perform surgery more easily. Through the above comparison, it is easy to find that when the tip of the forceps applies the same clamping force, the pinching force required by this device is much smaller than that of ordinary electrocoagulation forceps. At the same time, since the rotating shaft 5 is set close to the tip of the forceps, it has better stability than ordinary electrocoagulation forceps on the market. Even if the pinching force during pinching deviates from the direction of the forceps body, the front end tip of the forceps will not be misplaced, thus ensuring the accuracy of the surgical operation.

[0025] It should also be noted that when holding a conventional electrocoagulation forceps, in addition to pressing one of the forceps blades 3 with the thumb, the side joint of the index finger also needs to apply force to the other forceps blade 3 to maintain the stability of the electrocoagulation forceps. However, the present device can be used just like holding a TV remote control: the palm of the hand supports the forceps blade 3, and the thumb presses the front end of the forceps handle 2. It is not necessary to concentrate force on a single point on the palm supporting the forceps blade 3 to maintain the electrocoagulation forceps in a better way, which is more ergonomic.

[0026] Example 2

[0027] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5. The present invention provides an anti-dislocation electric coagulation tweezers with labor-saving kneading, comprising: a front tweezers blade 1, a tweezers handle 2 movably connected to one end of the front tweezers blade 1, a tweezers blade 3, and a tail connector 4. The tweezers blade 3 and the tweezers handle 2 are both fixedly connected to the tail connector 4. The front tweezers blade 1 is movably connected to the tweezers blade 3 via a rotating shaft 5 that passes through the front tweezers blade 1 and the tweezers blade 3, so that the front tweezers blade 1 can rotate relative to the tweezers blade 3 with the rotating shaft 5 as the base point. The tail connector 4 is fixedly provided with a connecting portion 8 at one end where the tweezers blade 3 is not fixed to the tweezers handle 2. A movable channel 6 is provided in the tweezers handle 2, and connecting rods are extended on both sides of the end of the front tweezers blade 1 away from the rotating shaft 5. The two connecting rods are connected by a connecting shaft 7 at one end away from the rotating shaft 5, and the front tweezers blade 1, the connecting rod, and the connecting shaft 7 enclose a movable space. The connecting shaft 7 passes through the movable channel 6 and the connecting shaft 7 can reciprocate in the movable channel 6. Anti-slip grooves 9 are provided on the tweezers handle 2. The rotating shaft 5 includes an axis body 13 and fixed heads 12 fixed to both ends of the axis body 13. An insulating plate 11 is also provided between the front tweezers 1 and the tweezers 3, and the insulating plate 11 is penetrated by the rotating shaft 5. The front tweezers 1, the tweezers 3 and the insulating plate 11 are all provided with through holes 14 of the same size for allowing the rotating shaft 5 to pass through. The tweezers handle 2 and the tweezers 3 are both provided with a clip 10 at one end close to the tail connector 4. The width of the end of the clip 10 away from the tail connector 4 is smaller than the width of the tweezers 3, and the width of the end of the clip 10 close to the tail connector 4 is equal to the width of the tweezers 3.

[0028] Among them, the connecting portion 8 can be used to connect objects such as power cords. When the medical staff presses the tweezers handle 2, the tweezers handle 2 will drive the connecting shaft 7 to move back and forth in the movable channel 6, thereby driving the application of a downward force to the front tweezers 1, causing the front tweezers 1 to rotate relative to the rotating shaft 5, thereby realizing the clamping process of the electrocoagulation tweezers. The provision of the anti-slip grooves 9 increases the friction of the tweezers handle 2 at the anti-slip grooves 9, ensuring that the medical staff will not slip between their fingers and the electrocoagulation tweezers during surgery. The insulating plate 11 ensures the insulation between the front tweezers 1 and the tweezers 3, so that when the electrocoagulation tweezers are powered on, there will be no mutual conduction between the front tweezers 1 and the tweezers 3, which will affect the conductive effect of the electrocoagulation tweezers. The clip 10 is used to ensure that it can be firmly fixed in the tail connector 4, so that the tweezers 3 and the tweezers handle 2 are not easy to fall off from the tail connector 4, and have a longer service life.
