Detailed Description
The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in fig. 1 to 4: the embodiment discloses a driving electric coagulation forceps of many connecting rods, including casing 1, tweezers handle 2, body 3 and tweezers body 4, on the basis of above-mentioned prior art, this embodiment still including set up in casing 1, and be used for tweezers body 4 to open or the drive connecting rod assembly 5 of centre gripping, tweezers body 4 includes first fixed block 41 and connects in first fixed block 41, and has the tweezers point 42 of opening the elastic force, the scalable connection casing 1 of body 3 one end, the other end cup joints in tweezers point 42, first fixed block 41 connects connecting rod assembly 5 through the stainless steel pipe 8 of wearing in body 3.
The connecting rod assembly 5 of this embodiment includes a first hinge block 51, a second hinge block 54, a first two connecting rods 52, a second two connecting rods 53 and a spring 6 for driving the first hinge block 51 to slide to the second hinge block 54, the first hinge block 51 and the second hinge block 54 are respectively connected to the tube body 3 and the stainless steel tube 8, one end of the first two connecting rods 52 is hinged to the first hinge block 51, the other end of the first two connecting rods 52 is hinged to one end of the second two connecting rods 53, and the other end of the second two connecting rods 53 is hinged to the second hinge block 54. That is to say: the two first connecting rods 52 and the two second connecting rods 53 are sequentially hinged end to form a parallelogram four-bar linkage, the first hinge blocks 51 and the second hinge blocks 54 are respectively arranged at a group of opposite corners of the parallelogram, and in some embodiments, in order to reduce the size of the connecting rod assembly 5, the two second connecting rods 53 are preferably arranged in a crossed manner, so that the angle between the two second connecting rods 53 is increased, and the distance between the first hinge blocks 51 and the second hinge blocks 54 can be accurately controlled.
In order to press the connecting rod assembly 5 conveniently, the dual-purpose tweezers further comprise tweezers handles 2 hinged to two sides of the shell 1 respectively, a tweezers handle connecting hole 11 matched with the second connecting rod 53 in position is formed in the side of the shell 1, a tweezers handle protrusion 22 is formed in the side of the tweezers handle 2, when the connecting rod assembly 5 is driven, the tweezers handle protrusion 22 penetrates through the tweezers handle connecting hole 11 to be connected with the second connecting rod 53, the tweezers handle 2 is connected to the side of the shell 1 through a tweezers handle elastic arm 21, and a flanging 531 matched with the tweezers handle protrusion 22 is further formed in the second connecting rod 53. Under the natural state, the forceps handle elastic arm 21 is bounced, so that the forceps handle bulge 22 is not contacted with the flanging 531, the distance between the first hinge block 51 and the second hinge block 54 is in the minimum state under the action of the spring 6, and the clamp 42 is in the open state. Wherein, the spring 6 is preferably sleeved on the tube 3, and two ends of the spring are respectively connected with the first hinge block 51 and the housing 1.
In order to reduce the volume of the housing 1, increase the compactness between the link assembly 5 and the tube 3, and enable the link assembly 5 to drive the forceps body 4 better, the tube 3 of the present embodiment passes through the first hinge block 51 and the second hinge block 54, the first hinge block 51 is slidably connected to the inside of the housing 1, and the second hinge block 54 is fixedly connected to the housing 1. When the link assembly 5 is actuated, the first hinge block 51 slides in the housing 1, and since the first hinge block 51 is connected to the tube 3, the tube 3 also slides relative to the housing 1 when the link assembly 5 is actuated.
Because the connecting rod assembly 5 only drives the tube body 3 to slide axially, the needle tube 8 penetrates through the tube body 3, and meanwhile, the needle tube 8 pulls the second fixing block 81, the axial position of the needle tube 8 needs to be fixed, in the embodiment, the stainless steel tube 8 is fixed through the regulator 7, the regulator 7 is fixed to the housing 1, the end part of the regulator is connected with the second hinge block 54, the regulator 7 is provided with a clamping groove 71, the needle tube 8 is connected with the clamping groove 71, the stainless steel tube 8 is clamped through the clamping groove 71, and the stainless steel tube 8 is connected with the clamping groove 71 through the second fixing block 81 and the second fixing block 82. The second fixing block 81 and the two passages 82 are fixed to the stainless steel pipe 8 and fitted to both sides of the engagement groove 71 in the actuator 7, so that the needle pipe 8 does not axially move relative to the actuator 7.
Because in the use, need to carry on the circular telegram to the tweezers body 4, and the tweezers body 4 opens and presss from both sides tightly and is directly driven through the inside extrusion of body 3 tip, therefore body 3 needs to reach insulating effect, body 3 of this embodiment includes inner tube 31 and cup joints the outer tube 32 in inner tube 31 outside, and inner tube 31 is the metal tube, wherein the supporting role, and outer tube 32 is the insulating tube, and tweezers body 4 is connected in the tip of outer tube 32, and inner tube 31 and tweezers body 4 contactless, and inner tube 31 is equipped with the wire that is used for connecting the power.
For convenience of operation, the housing 1 is further provided with a housing cover 12, and the housing cover 12 is further provided with a finger ring 13.
In use, in a natural state, the spring 6 drives the distance between the first hinge block 51 and the second hinge block 54 to be in a minimum state, and the clamp 42 is in an open state in a self elastic state. When the forceps handle 2 is pressed, the forceps handle bulge 22 penetrates through the forceps handle connecting hole 11 to press the second connecting rod 53, the first hinge block 51 slides in the shell 1, and the needle tube 8 moves axially relative to the tube body 3. The needle tube 8 pulls the second fixed block 81, the forceps tip 42 is pulled to move toward the inside of the tube body 3, and the end of the tube body 3 continuously presses the forceps tip 42, so that the forceps tip 42 is clamped. When the forceps handle 2 is released, the forceps tip 42 is released.
The first link 52 and the second link 53 of the present embodiment are rigid structures, and do not bend during operation, and compared to the spring plate in the prior art, the present embodiment drives the forceps tips 42 to clamp and open through the link assembly 5. Compared with the coupling spring piece driving in the prior art, the connecting rod assembly 5 of the present embodiment has better working stability, and at the same time, the clamping control of the forceps tips 42 is easier to achieve precise control. Because the connecting rod assembly 5 is symmetrically distributed on two sides of the pipe body 3 by taking the pipe body 3 as a neutral center, the driving force for the pipe body 3 and the stainless steel pipe 8 can be ensured to be more centered, and no extra radial deviation can be generated in the working process.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
