Background

Ultrasonic blades used in surgery are ultrasonic-based surgical instruments that convert ultrasonic signals into mechanical vibrations via an ultrasonic transducer, commonly used for cutting tissue. High frequency scalpels (scalpels for short) are also a common surgical instrument commonly used for sealing blood vessels and require high frequency electrical energy to drive. The ultrasonic electrotome (for short, the ultrasonic electrotome) has the advantages of the ultrasonic electrotome and the electrotome, and is beneficial to improving the operation effect.

The ultrasonic energy conversion device suitable for the super-electric hybrid energy platform is also called an ultrasonic transducer (hereinafter referred to as a transducer for short), not only converts ultrasonic energy (such as ultrasonic current with the frequency of 55 kHz) for driving the ultrasonic knife function into mechanical vibration and then transmits the mechanical vibration to a tool bit at the front end of the surgical instrument, but also transmits high-frequency energy (such as high-frequency current with the frequency of 470 kHz) to a jaw at the front end of the surgical instrument according to requirements as an electric channel between the surgical instrument and energy source equipment, and transmits some signals generated by the instrument end for control or detection back to other functions such as the equipment end.

When it is necessary to perform a surgical operation using super-electric hybrid energy, it is necessary to transmit a high-frequency current to the distal end of the operation section, and the transmission path of the energy needs to be specially designed to be realized. Therefore, the design of the structure is one of important links for realizing the operation of surgical super-electric hybrid energy.

As shown in fig. 2, the surgical instrument 100 adapted for use with a super-electric hybrid energy platform includes a hand-held housing 110, an electrically conductive slip ring 20, and an operating portion 120.

It should be noted that, in the various embodiments described below, the "proximal end" of the operating portion, the outer sleeve, the inner sleeve, or the waveguide rod refers to the side of the components that is adjacent to the hand-held housing; "distal" refers to the side of the components that is remote from the hand-held housing.

According to the embodiment of the utility model, an electrode ring 111 and a first limiting groove 112 are arranged inside the handheld housing 110. The conductive slip ring 20 is mounted in the first limiting groove 112 and electrically connected to the electrode ring 111, for example, via a flat cable 113 shown in fig. 2.

As shown in fig. 2, an electrode ring 111 may be provided inside the hand-held housing 110 near the transducer for connection with one electrode of a high frequency current line in the connected transducer 200.

The operation part 120 includes a waveguide rod 121 and an outer sleeve 122 sleeved outside the waveguide rod 121. The distal end of the waveguide rod 121 is a blade 1211 and the proximal end is within the hand held housing 110, connected to the other electrode of the high frequency current line in the attached transducer 200. For example, the waveguide rod 121 may be screw mounted with the conductive rod of the connected transducer. The distal end of the outer sleeve 122 is connected with the jaw 124, and the elastic thimble 10 is arranged outside the proximal end, and the elastic thimble 10 is contacted with the inner wall of the conductive slip ring 20. The waveguide rod 121 and the outer sleeve 122 are both conductors and insulated from each other so that two electrodes for high frequency current can be formed at the tool bit and the jaw 124.

According to the embodiment of the utility model, the distance between the elastic thimble and the proximal end of the outer sleeve is 0-10 mm, and the outer sleeve needs to extend into the handheld shell, so that the elastic thimble is closer to the proximal end of the outer sleeve, the occupation of the internal space of the handheld shell can be reduced, and the design of other circuits, supporting structures and other contents in the handheld shell is more convenient; or the volume of the hand-held housing may be saved.

According to an embodiment of the present utility model, the elastic ejector pin 10 may be a spring ejector pin. The spring thimble is also called a probe, is a contact medium for electric test and is a high-end precise electronic hardware component. The surface of the spring thimble is usually plated with gold to improve the corrosion resistance, mechanical property, electrical property and the like. The spring thimble has the advantages of small size, high precision and light weight, and is widely applied to the fields of aviation, aerospace, military communication, military electronics, automobiles, vehicle navigation, medical equipment, wireless equipment, data communication equipment and the like.

According to an embodiment of the utility model, the transducer 200 may include a piezoelectric assembly, a first electrode, and a second electrode. In the state in which the transducer 200 is mounted, the surgical instrument 100 is in communication with the waveguide 121 via the electrode ring 111 and secured, for example by screwing, to the first electrode of the transducer 200. The second electrode of the transducer 200 is in communication with the jaw 124 via the electrode ring 111, the conductive slip ring 20, the outer sleeve 122, the first and second electrodes being configured to transmit high frequency electrical signals.

The surgical instrument 100 having the above-described structure, when connected to the transducer 200, transmits a high-frequency current to the jaw 124 and the cutter head via the outer sleeve 122 and the waveguide rod 121, and at the same time the waveguide rod 121 can also obtain ultrasonic vibrations from the connected transducer 200, so that a super-electric hybrid surgical operation can be performed at the execution end, which is advantageous for obtaining a better surgical effect.

Fig. 3 and 4 schematically illustrate enlarged partial views of a surgical instrument 100 with an electrically conductive slip ring and a hidden electrically conductive slip ring, respectively, according to an embodiment of the present utility model.

As shown in fig. 3 and 4, the proximal end of the operation portion 120 protrudes into the interior of the hand-held housing 110. The operation portion 120 is provided with an elastic thimble 10, and specifically, the elastic thimble 10 is disposed on a proximal end surface of the outer sleeve 122. The conductive slip ring 20 is disposed outside the elastic thimble 10 and is mounted in the first limiting groove 112. The top end of the elastic thimble 10 contacts the inner wall of the conductive slip ring 20.

According to an embodiment of the present utility model, the surgical instrument 100 further includes a knob 125 secured to the exterior of the outer cannula 122, disposed at the proximal end of the outer cannula 122. The knob 125 may extend at least partially into the hand-held housing 110 and be rotatably coupled thereto. The knob 125, when rotated, can rotate the outer sleeve, thereby adjusting the orientation of the jaws 124. As shown in fig. 4, the knob 124 is provided with a receiving groove at an end near the hand-held housing 110 for receiving the elastic thimble 10.

The surgical instrument 100 may also include an inner cannula 123 disposed within the outer cannula 122, in accordance with an embodiment of the present utility model.

Fig. 5 schematically illustrates a schematic view of the distal ends of the outer sleeve 122 and the inner sleeve 123 of an embodiment of the present utility model, and fig. 6 is a schematic view after the jaws 124 are mounted on the basis of fig. 5.

As shown in fig. 5 and 6, the distal end of the inner sleeve 123 may be provided with a fixation hole 1231. The distal end of the outer sleeve 122 has a tongue 1221, the tongue 1221 has a through hole 1222, and the jaw 124 is connected to the inner sleeve 123 and the outer sleeve 122 through the through hole 1222 and the fixing hole 1231, and when the inner sleeve 123 moves, the jaw 124 is opened or closed.

For example, the jaw 124 may have a catch for mating with the securing aperture 1231, the jaw 124 being rotatably connected with the inner sleeve 123. Jaw 124 also has a through hole, and a pin may be inserted through outer sleeve 122 and the through hole in jaw 124 to rotatably connect jaw 124 to outer sleeve 122. Thus, with the inner cannula 123 moved back and forth, the jaws 124 rotate relative to the inner cannula 123 and outer cannula 122 to effect a surgical action.

Fig. 7 schematically illustrates a front view of the elastic ejector pin 10 according to an embodiment of the present utility model.

As shown in fig. 7, the elastic ejector pin 10 includes a fixed portion 12 and a telescopic portion 11, and the height of the fixed portion 12 is larger than the height of the telescopic portion 11 so as to be able to enter into the inner space of the fixed portion 12 as much as possible when the telescopic portion 11 is compressed, thereby increasing the amount of telescopic motion. The amount of telescoping is 80% -95% of the height of the telescoping portion 11. For example, the height of the telescopic portion 11 may be 0.95mm, and the telescopic amount may be 0.90mm, in which case the telescopic amount is 94.7% of the height of the telescopic portion. In the limited space of the precision instrument, it is advantageous to increase the amount of telescoping as much as possible.

According to an embodiment of the present utility model, the bottom surface of the fixing portion 12 has a diameter of 1mm to 3mm, for example, 2mm. The elastic ejector pin 10 may be fixed to the proximal surface of the outer sleeve 122 by arc welding, for example. Because the surface of the outer sleeve 122 is a curved surface, the elastic thimble with smaller bottom area is selected to be fixed more easily.

According to an embodiment of the utility model, the height of the fixing portion 12 is 2mm-3mm, for example 2.5mm. The telescopic part 11 is made of brass with gold plated surface, has the height of 0.8mm-1.2mm, such as 1mm, and the diameter of 0.8mm-1.2mm, such as 0.95mm, and the top end is a hemispherical surface.

Fig. 8 schematically illustrates the outer sleeve 122, the inner sleeve 123 and the proximal end of the waveguide rod 121 according to an embodiment of the present utility model, fig. 9 is a schematic view after the knob 125 and the conductive slip ring 20 are mounted on the basis of fig. 8, and fig. 10 is a schematic view of the assembly shown in fig. 9 viewed from the axial direction.

As shown in fig. 8-10, the waveguide rod 121, the inner sleeve 123 and the outer sleeve 122 are respectively arranged from inside to outside, and the elastic thimble 10 is arranged on the surface of the outer sleeve 122. The number of elastic pins 10 may be one or more, and in the embodiment illustrated in fig. 8-10, two elastic pins 10 are provided at opposite positions of the outer sleeve 122.

As shown in fig. 9 and 10, the knob 125 is fixed to the outside of the outer sleeve 122. The knob 125 may be held stationary with respect to the outer sleeve 122 and the inner sleeve 123 by a pin to prevent relative rotation therebetween. The conductive slip ring 20 is disposed outside the elastic thimble 10, and the inner diameter thereof is designed such that the elastic thimble 10 cannot be fully unfolded, so that a stable connection between the conductive slip ring 20 and the elastic thimble can be maintained even if the conductive slip ring 20 rotates in the first limiting groove 112.

According to the embodiment of the utility model, the inner surface of the conductive slip ring 20 is provided with a limiting structure for preventing the elastic thimble 10 from sliding out of the conductive slip ring 20 from the side surface, so that the stability of connection is further ensured. For example, the radius may vary continuously or stepwise across the width of the inner wall of the conductive slip ring 20 such that the radius of at least one edge is smaller than the radius of the middle portion to prevent the resilient spike from sliding off the conductive slip ring from that edge. In some embodiments, the radius of both edges may be smaller than the radius of the intermediate region, i.e. the second limiting groove is formed in the intermediate region. In other embodiments, the radius of one edge is smaller than the radius of the other edge, and the radius of the middle region may be continuously variable, or a stepped configuration may be formed so that the elastomeric thimble does not slip out of one side of the conductive slip ring.

The surgical instrument 100 may also include a third electrode and a signal circuit board in accordance with an embodiment of the present utility model.

Fig. 11 schematically illustrates a schematic view of the interior of a hand held housing 110 in accordance with another embodiment of the present utility model.

As shown in fig. 11, the third electrode 114 may be a ring-shaped contact electrode. The third electrode 114 may be fixed in the same electrode disk as the electrode ring 111 to form a concentric electrode ring. The electrode disk is shaped and positioned to mate with the attached transducer 200. The third electrode 114 may be used in connection with a fourth electrode of the transducer 200 to implement a signal current line. A through hole is provided in the center of the electrode disk to facilitate passage of the conductive rod of the transducer 200 therethrough for connection with the proximal end of the waveguide rod 121. The conductive slip ring 20 is at the front of the hand-held housing 111 so that the outer sleeve 122 connects the high frequency current line through the conductive slip ring 20.

The signal circuit board 115 is disposed inside the handheld housing 110. The two electrodes of the signal circuit board 115 are respectively connected with the electrode ring 111 and the third electrode 114, and are used for generating signals, and are communicated with the host 300 through a loop formed by the third electrode 114 and the electrode ring 111, so that the functions of controlling, optimizing the surgical process and the like are realized, and the improvement of the surgical effect is facilitated.

Thereby, the ultrasonic vibration generated by the transducer 200 is transmitted to the waveguide rod 121. One electrode of the high frequency current line is transferred to the outer sleeve 122, and from there to the jaw 124, through the electrode ring 111 and the conductive slip ring 20. The other electrode of the high-frequency current line is directly transferred to the bit 1211 via the waveguide rod 121. One electrode of the signal current line is connected to a signal current plate 115 via an electrode loop 111 of the surgical instrument 100. The other electrode of the signal current line is connected to a signal circuit board 115 via a third electrode 114 of the surgical instrument 100.

According to an embodiment of the utility model, the signal circuit board 115 may be a passive circuit board, the required supply current of which is obtained from the connected transducer 200 via the electrode ring 111 and the third electrode 114. Unlike the three-electrode structure of the switch circuit board in the existing surgical instrument, the signal circuit board in the embodiment of the utility model can obtain the power supply current only by connecting two electrodes and simultaneously realize the function of signal transmission.

With the above-described structure, the electrode ring 111 is connected not only to one electrode of the high-frequency current line in the transducer 200 but also to one electrode of the signal current line. The high-frequency current line and the signal current line share the electrode connection mode, so that one electrode in the handle can be reduced, the structure of the handle is simplified, and the risk caused by poor contact of the electrodes is also reduced. Because the high-frequency current is usually a differential signal with high voltage (220V for example), the signal current is usually a level signal with low voltage (12V for example), the electrodes are shared during the current transmission of two different signals, the crosstalk generated between the two signals is controlled within an acceptable range, and the safety and the stability of the system are ensured.

Surgical instruments according to embodiments of the present utility model may also include an input assembly. The input assembly is disposed on the hand held housing 110. The signal circuit board 115 may be located, for example, inside the hand held housing 110 near the input assembly. The signal circuit board 115 is capable of receiving input commands from an input assembly to generate a first signal that is transmitted to the device side via the connected transducer 200.

The input assembly may be a push key and/or a slide key in contact with the signal circuit board 115. For example, the input assembly may include two finger buttons for an operator to press with his fingers while holding, and a sliding key for gear selection. In order to adapt to the operation habit of an operator, the sliding key switches can be two groups and are respectively arranged at two sides of the handle. The input component may also be a touch screen, in electrical communication with the signal circuit board 115. The input assembly may also be a wireless remote control, which is in wireless communication with the signal circuit board 115. The instructions input by the input component can be set according to requirements, for example, two finger keys can be used for selecting energy gears, and a sliding key can be used for selecting more refined energy modes, for example, one energy mode is used for outputting ultrasound and then outputting electricity, and the other energy mode is used for outputting super-electricity and then outputting electricity.

According to an embodiment of the present utility model, the signal circuit board 115 may also generate the second signal based on detecting the operation state of the operation portion. For example, by detecting the impedance value of the cutter head and the jaw 124 after closing, it is determined whether abnormal wear occurs at the jaw 124, so as to send out corresponding prompt information.

In accordance with an embodiment of the present utility model, the surgical instrument 100 may further include an output assembly disposed on the hand-held housing 110, and the signal circuit board 115 may transmit a second signal to the output assembly. For example, the output component may be an LED indicator, and the second signal indicates to the operator whether the operating state of the operating portion is normal by lighting the indicator of different colors, so that the operator can conveniently detect the fault. The output assembly can also be an audio indicating component which prompts the operator through different warning sounds, or an indicating component which combines audio with a lamp. On the other hand, the second signal generated by the detection of the signal circuit board 115 may also be transmitted to the device side, and may be processed by the device side to prompt the operator, or used for other purposes with improved performance, which the present utility model is not limited to.
