Description

Surgical instrument and superelectric hybrid energy platform

Technical Field

The specification relates to the technical field of medical instruments, and in particular relates to a surgical instrument and an superelectric hybrid energy platform.

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.

In order to obtain better operation effect when the ultrasonic electric knife is applied, an ultrasonic electric hybrid energy platform can be built. In the platform, including instruments for performing surgical operations, energy transmission lines, transducers involving energy conversion, electrical connection means, and energy source devices, etc., special designs are required to ensure safety and stability when the system is in operation.

In superelectric hybrid energy platforms, a stop is typically pressed in posteriorly in order to secure the tissue pad on the jaws. For stability after installation, the stop needs to be sized larger than the jaws. However, since the stopper has limited elasticity, the pressing process is very difficult and the installation difficulty is high.

Detailed Description

Hereinafter, exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily implement them. In addition, for the sake of clarity, portions irrelevant to description of the exemplary embodiments are omitted in the drawings.

In this disclosure, it should be understood that terms such as "comprises" or "comprising," etc., are intended to indicate the presence of features, numbers, steps, acts, components, portions, or combinations thereof disclosed in this specification, and are not intended to exclude the possibility that one or more other features, numbers, steps, acts, components, portions, or combinations thereof are present or added.

In addition, it should be noted that, without conflict, the embodiments of the present disclosure and features of the embodiments may be combined with each other. The present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

In the context of surgical applications of superelectric hybrid energy, the tips and jaws of surgical instruments are intended to employ the superelectric hybrid energy to perform a surgical procedure. In some cases, two poles of high-frequency current are formed after tissue is clamped between the cutter head and the jaw, so that the function of the electric knife is realized. In other scenarios, the tool tip performs only a single ultrasonic blade function. In addition, it is sometimes desirable to use both the electric and ultrasonic blade functions and to distribute energy between them to better accommodate a variety of complex surgical scenarios.

In superelectric hybrid energy platforms, a stop is typically pressed in posteriorly in order to secure the tissue pad on the jaws. For stability after installation, the stop needs to be sized larger than the jaws. However, since the stopper has limited elasticity, the pressing process is very difficult and the installation difficulty is high.

Embodiments of the present disclosure provide a surgical instrument suitable for use with a super-electric hybrid energy platform, including a hand-held housing, an outer cannula, an inner cannula, a waveguide rod, and a jaw. The distal end of the outer sleeve is provided with a tongue-shaped part, and the tongue-shaped part is provided with a first through hole. The inner sleeve is arranged inside the outer sleeve, and a fixing hole is formed in the far end of the inner sleeve. The waveguide rod is arranged inside the inner sleeve, and the distal end of the waveguide rod is a tool bit. The jaw is connected to the inner sleeve and the outer sleeve through the first through hole and the fixing hole, the jaw is in an open or closed state under the condition that the inner sleeve moves, the jaw comprises a limiting protrusion, and the limiting protrusion is in contact with the tongue-shaped part to generate a limiting effect on the rotation of the jaw under the condition that the jaw is in a closed state.

According to the technical scheme of the embodiment of the disclosure, the plug-in check block comprising the male head and the female head is adopted, and the size of the plug-in check block can be designed to be closer to the check block mounting position of the jaw, so that the mounting difficulty is reduced, and the assembly cost is also reduced.

The following describes in detail the technical solutions provided by the embodiments of the present disclosure with reference to the accompanying drawings.

It should be noted that, in the various embodiments described below, the "proximal" ends of the outer cannula, inner cannula, waveguide rod, jaw, or tissue pad all refer 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.

Fig. 1 schematically illustrates a schematic diagram of a superelectric hybrid energy platform to which embodiments of the present disclosure are applied.

As shown in FIG. 1, the superelectric hybrid energy platform includes a surgical instrument 100, a transducer 200, and a host 300. Wherein the transducer 200 is mounted to the surgical instrument 100 and connected to the host 300 by a cable. The host 300 includes an ultrasonic signal generating device and a high frequency electrical signal generating device for providing ultrasonic energy and high frequency electrical energy to the surgical instrument 100 via the transducer 200.

Fig. 2 schematically illustrates a schematic view of a surgical instrument 100 of an embodiment of the present disclosure, and fig. 3 schematically illustrates a partial schematic view of a distal region of the surgical instrument 100 of an embodiment of the present disclosure.

As shown in fig. 2 and 3, the surgical instrument 100 adapted for use with a super-electric hybrid energy platform includes a hand-held housing 110 and an operating portion. The manipulation portion may include an outer sleeve 122, an inner sleeve 123, a waveguide rod, a jaw 124, and the like. The inner sleeve 123 is disposed inside the outer sleeve 122 and outside the waveguide rod. The distal end of the waveguide rod is a blade 1211, which can output ultrasonic energy, and in cooperation with the jaws 124, can also perform tissue clamping actions.

According to an embodiment of the present disclosure, the proximal end of the waveguide rod is connected within the hand-held housing 110 to one electrode of the high frequency current line in the connected transducer 200. For example, the waveguide rod may be screw mounted with the conductive rod of the connected transducer 200. The distal end of the outer sleeve 122 is connected to the jaw 124, and an electrode is provided on the outside of the proximal end, which is connected to the other electrode of the high frequency current line of the connected transducer 200. The waveguide rod and the outer sleeve 122 are both conductors and insulated from each other so that two electrodes of high frequency current can be formed at the bit 1211 and the jaw 124. In addition, waveguide rod 121 may also obtain ultrasonic vibrations from the attached transducer 200, so that a superhybrid surgical procedure may be performed at blade 1211 and jaw 124, which may be advantageous for better surgical results.

As shown in fig. 3, the front section of jaw 124 is flanked by jaw electrodes 1243 in accordance with an embodiment of the present disclosure. When the jaws are closed, knife 1211 and jaw 124 grip tissue, and a discharge is created between knife 1211 and jaw electrode 1243 to perform a surgical procedure.

According to embodiments of the present disclosure, jaws 124 are provided with a slide, and tissue pad 1241 can be slid into the slide of jaws 124 and then secured. For example, jaws 124 may also be fitted with a splice stop 10. When the tissue pad 1241 is installed, after sliding into the slideway of the jaw 124, the insertion stop block 10 is fixed at the entrance of the slideway, so as to prevent the tissue pad 1241 from sliding out, and play a role in fixation. The shape of the plugging stop block can be matched with the shape of the jaw.

As shown in fig. 2, surgical instrument 100 may further include a knob 125, according to embodiments of the present disclosure. The knob 125 is fixed to the outside of the outer sleeve 122, disposed at the proximal end of the outer sleeve 122. The knob 125 may extend at least partially into the hand-held housing 110 and be rotatably coupled to the hand-held housing 110. The knob 125, when rotated, can rotate the outer sleeve 122, thereby adjusting the direction of the jaws 124.

Fig. 4 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 disclosure, and fig. 5 is a schematic view after the jaws 124 are installed on the basis of fig. 4.

As shown in fig. 4 and 5, the distal end of the inner sleeve 123 may be provided with a fixing hole 1231. The distal end of the outer sleeve 122 has a tongue 1221, the tongue 1221 is provided with a first through hole 1222, and the jaw 124 is connected to the inner sleeve 123 and the outer sleeve 122 through the first 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 jaws 124 are secured to the securing holes 1231 by securing members (e.g., hooks) such that the jaws 124 are rotatably coupled to the inner sleeve 123. Surgical instrument 100 can further include a pin that passes through first throughbore 1222 and a second throughbore in jaw 124 to rotatably couple jaw 124 to outer sleeve 122. Thus, when the inner sleeve 123 moves forward and backward, the jaws 124 rotate with respect to the inner sleeve 123 and the outer sleeve 122 to be opened or closed, thereby performing a surgical operation.

Fig. 6 schematically illustrates a schematic view of a jaw of an embodiment of the present disclosure, and fig. 7 schematically illustrates an installation schematic view of a splice block of an embodiment of the present disclosure.

As shown in fig. 6 and 7, the jaw 124 includes a jaw electrode 1243, a slideway 1244, a mounting hole 1245, a second through hole 1246 and a fixture 1247. The mounting holes 1245 are located at one end of the slide 1244, specifically at the entrance of the slide. Tissue pad 1241 may be mounted to slide 1244 and then plug-in stop 10 mounted at mounting hole 1245 to secure tissue pad 1241 against falling out.

As shown in fig. 7, the insertion stopper 10 includes a female head 11 and a male head 12. The male head 12 is inserted and fixed with the female head 11 through the mounting hole 1245 to achieve fixation. For example, as shown in fig. 7, female 11 may be on the same side of jaw 124 as tissue pad 1241 and male 12 may be on the other side of jaw 124. The plug-in check block comprising the male head and the female head is adopted, the size of the plug-in check block can be designed to be closer to the check block mounting position of the jaw, the mounting difficulty is reduced, and the assembly cost is also reduced.
