Detailed Description

For a better understanding and explanation of the present invention, reference will now be made in detail to the present invention as illustrated in the accompanying drawings. The present invention is not limited to these specific embodiments only. Rather, modifications and equivalents of the invention are intended to be included within the scope of the claims.

It should be noted that numerous specific details are set forth in the following detailed description. It will be understood by those skilled in the art that the present invention may be practiced without these specific details. In the following detailed description of various embodiments, structures and components well known in the art are not described in detail in order to not unnecessarily obscure the present invention.

Referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment of a high-frequency electric and ultrasonic dual-output multipurpose shears according to the present invention, which includes a clamping nozzle 32, a tool bar 33, an outer sleeve 1, a trigger 9 and a handle housing 37, wherein:

the mouthpiece 32 is rotatably connected to the outer sleeve 1 relative to the arbor 33, for example the mouthpiece 32 is connected to the outer sleeve 1 by a pin about which the mouthpiece 32 can rotate, it is clear that after a certain angle of rotation of the mouthpiece 32 towards the arbor 33 the distance between the mouthpiece 32 and the arbor 33 becomes smaller, which is sufficient to more firmly grip the body tissue when the distance between the mouthpiece 32 and the arbor 33 is sufficiently small.

The outer sleeve 1 is sleeved outside the cutter bar 33, the front end of the cutter bar 33 extends to the outside of the outer sleeve 1, the front end of the cutter bar 33, namely one end of the cutter bar 33 close to the clamping nozzle 32, is a part of the cutter bar 33 directly contacted with human tissues in an operation treatment scene, and ultrasonic energy transmitted through the cutter bar 33 is output at the front end of the cutter bar 33. Accordingly, the rear end of the shaft 33 extends inside the outer sleeve 1 toward the handle housing 37 (not shown in fig. 1), i.e., the end of the shaft 33 remote from the clamping jaw 32, and generally the rear end of the shaft 33 extends into the handle housing 37 and is connected to an ultrasonic transducer arranged in the handle housing 37. The cutter bar 33 is insulated from the outer sleeve 1, and the method for fixing the cutter bar 33 can use a glue-coated pin 15 shown in figure 2.

The trigger 9 is disposed on the handle housing 37, and the rotation of the trigger 9 can drive the clamping nozzle 32 to rotate relative to the cutter bar 33, specifically, an important function of the handle housing 37 is to provide for an operator using the high-frequency electric and ultrasonic dual-output multipurpose shears to perform a holding operation, and the rotation of the trigger 9 is usually achieved by the operator applying an external force to the trigger 9.

The nipple 32 is connected to the high-potential end of the high-frequency current circuit through the outer sleeve 1, and the cutter bar 33 is connected to the low-potential end of the high-frequency current circuit. When the trigger 9 is not rotated, the clamping nozzle 32 and the cutter bar 33 are kept in a separated state, and because the cutter bar 33 is insulated from the outer sleeve 1, the high-frequency current cannot flow from the clamping nozzle 32 to the cutter bar 33, and the high-frequency current loop is in an open state; in the operation treatment scene, when the clamping nozzle 32 rotates towards the cutter bar 33 and the distance between the clamping nozzle 32 and the cutter bar 33 is small enough, the human tissue is clamped by the scissors-shaped structure formed by the clamping nozzle 32 and the cutter bar 33, the clamping nozzle 32 and the cutter bar 33 are electrically conducted through the human tissue, and the high-frequency current in the clamping nozzle 32 connected with the high-potential end of the high-frequency current loop flows to the cutter bar 33 connected with the low-potential end of the high-frequency current loop.

Preferably, the outer sleeve 1 is screwed and fixed relative to an ultrasonic transducer (not shown in fig. 1) inserted into the handle housing 37 by a screwing structure 34 provided on the handle housing 37, so that the knife bar 33 is fixed relative to the ultrasonic transducer.

In order to more clearly illustrate the internal structure of the high-frequency electric and ultrasonic dual-output multi-purpose scissors provided by the present invention, please refer to fig. 1 and fig. 2, fig. 2 is an exploded view of an embodiment of the high-frequency electric and ultrasonic dual-output multi-purpose scissors according to the present invention, and the exploded view sequentially combines various components to form the structure of the high-frequency electric and ultrasonic dual-output multi-purpose scissors shown in fig. 1. To further explain in detail fig. 2, in order to facilitate assembly and disassembly for maintenance, the handle housing 37 is designed to be composed of the left housing 2 and the right housing 3, and the left housing 2 and the right housing 3 are combined to form an internal cavity for accommodating components that must be enclosed in the handle housing 37. Firstly, a section of the outer sleeve 1 inserted into the screwing structure 34 is designed to be radially outward extended, so that the rear section of the outer sleeve 1 has a larger diameter than the front section thereof, and the screwing structure 34 limits the rear section of the outer sleeve 1, so that the outer sleeve 1 and the handle housing 37 are relatively fixed. Typically, the screwing structure 34 includes a thumb wheel 4, a torsion spring 23, a first ratchet assembly 5 and a second ratchet assembly 6 which are sleeved outside the outer sleeve 1 along the axial direction of the outer sleeve 1 and are combined together, the torsion spring 23 provides a feedback force when the thumb wheel 4 is dialed, the thumb wheel 4 is fixedly connected with the first ratchet assembly 5, the first ratchet assembly 5 is meshed with the second ratchet assembly 6, and after the thumb wheel 4 is dialed, the thumb wheel 4 is tightly attached to and presses the rear section of the outer sleeve 1, so that the outer sleeve 1 is limited and fixed, since the outer sleeve 1 is connected and fixed with the cutter bar 33, the cutter bar 33 is also limited and fixed, and the first ratchet assembly 5 and the second ratchet assembly 6 mainly prevent the limiting state of the cutter bar 33 from being easily released.

Further, in order to allow the high-frequency current to flow smoothly to the outer sleeve 1, it is necessary to establish a conductive path to the outer sleeve 1 for the high-frequency current. Referring to fig. 1 to 3, fig. 3 is a schematic view of an internal conductive structure of the high-frequency electric and ultrasonic dual-output multipurpose scissors shown in fig. 2, as shown in fig. 2, a conductive ring 26 sleeved on the second ratchet assembly 6 is penetrated by a screw 27, and since the outer sleeve 1 is located inside the second ratchet assembly 6, the screw 27 can contact the outer sleeve 1, so that the conductive ring 26 is electrically connected to the outer sleeve 1 through the screw 27.

Due to the conductive ring 26, no matter the knife bar 33 is subjected to unidirectional ultrasonic vibration or composite ultrasonic vibration, the conductive pin 13 can continuously keep good contact with the conductive ring 26, and the conductive pin 13 and the wire ring 26 are kept in an electrically conductive state, so that the outer sleeve 1 can maintain a good high-frequency current conductive state, and cannot be easily disconnected due to the fact that the conductive device is separated from contact.

As shown in fig. 3, the front conductive pin 13 is electrically conducted with the rear conductive pin 31 through a wire 30, more specifically, the wire 30 connects the front hub 28 and the rear hub 29, the rear conductive pin 31 is disposed on the rear hub 29, and the rear hub 29 is fixed relative to the right housing 3. Meanwhile, the rear conductive needle 31 is electrically conducted with the high-potential end of the high-frequency circuit, high-frequency current is transmitted to the rear needle base 29 from the rear conductive needle 31, transmitted to the front needle base 28 and the front conductive needle 13 through the rear needle base 29, transmitted to the outer sleeve 1 through the conductive ring 26 in contact with the front conductive needle 13 through the screw 27, further transmitted to the clamping nozzle 32 through the outer sleeve 1, and when the clamping nozzle 32 and the cutter bar 33 are in contact with human tissues together, transmitted to the cutter bar 33 through the human tissues, flowed to the ultrasonic transducer through the cutter bar 33, and finally output from the negative electrode of the ultrasonic transducer to a host device generating the high-frequency current, so that the closed high-frequency circuit is completed.

In order to control when the ultrasonic energy for cutting or coagulation outputted on the knife handle 33 is outputted, the rear end of the knife rod 33 is connected to one or more manual control button circuits, and the manual control button circuits are triggered by buttons arranged on the handle housing 37 to generate a manual control signal, as shown in fig. 2, the buttons are, for example, a button group 11 shown in fig. 2, the button group 11 may include a cutting button 35 and a coagulation button 36 shown in fig. 1, and the corresponding manual control button circuit generates a corresponding manual control signal through the buttons in the button group 11, and the manual control signal is used for controlling a host computer for generating ultrasonic energy to generate corresponding ultrasonic energy. Referring to fig. 1 and 2, the manual control key circuit corresponding to the cutting key 35 and the coagulation key 26 respectively is formed by combining a flexible circuit board 25, a conductive ring mounting seat 14a, a manual control signal outer ring 17a and a manual control signal inner ring 18a, the manual control signal outer ring 17a and the manual control signal inner ring 18a are mounted on the conductive ring mounting seat 14a, and the flexible circuit board 25 is electrically connected with the manual control signal outer ring 17a and the manual control signal inner ring 18a respectively to form manual control signal conductive loops for cutting and coagulation respectively.

Referring to fig. 6 and fig. 1 to 5, fig. 6 is a schematic view of an insulating structure of a knife bar and an outer sleeve portion in each embodiment shown in fig. 1 to 5, wherein the high-frequency electric and ultrasonic dual-output multipurpose scissors shown in fig. 6 further includes an inner sleeve 38, and the inner sleeve 38 is sleeved outside the knife bar 33 and extends inside the outer sleeve 1. The front end of the inner sleeve 38 is connected with the clamping nozzle 32, the rear end of the inner sleeve 38 is connected with the trigger 9 through a transmission structure, and the rotation of the trigger 9 can drive the inner sleeve 38 to move axially through the transmission structure so as to drive the clamping nozzle 32 to rotate relative to the cutter bar 33; knife bar 33 is insulated from inner sleeve 38.

The trigger 9 is connected to the slide 10 via a connecting rod 12, and the slide 10 is provided with a clamping end which is cooperatively connected to the slide connecting member 7, for example, a clamp-type clamping arm shown in fig. 2 or 4 and provided on the slide 10, and the clamp-type clamping arm is combined with the slide connecting member 7, so that the slide connecting member 7 can be moved synchronously by the movement of the slide 10. The wave spring 24 is disposed between the front retainer 16 and the rear retainer 8, and applies an elastic force to the slider connector 7 through the front retainer 16. When the trigger 9 is pressed down, the trigger 9 drives the slider 10 to move through the connecting rod, further the slider 10 drives the slider connecting piece 7 to move synchronously, the moved slider connecting piece 7 is connected with the rear end of the inner sleeve 38, on one hand, the inner sleeve 38 is driven to move axially, the clamping nozzle 32 rotates towards the cutter bar 33, on the other hand, the front check ring 16 extrudes the wave spring 24, and the wave spring 24 deforms. When the trigger 9 is released, the wave spring 24 tends to deform from the squeezed state to the relaxed state, so that the rear end of the inner sleeve 38 moves toward the nozzle 32, and the nozzle 32 further rotates to return to the state of forming an angle with the knife bar 33.
