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 the ultrasonic hybrid energy platform, when the jaw and the cutter head are closed, if the precision of the surgical instrument is insufficient, vibration when the cutter head outputs ultrasonic energy is overlapped, so that the cutter head can be in direct contact with the jaw electrode, and the risk of short circuit exists.
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, a jaw, and a tissue pad. The distal end of the outer sleeve is provided with a tongue-shaped part, and the tongue-shaped part is provided with a 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 with the inner sleeve and the outer sleeve through the through holes and the fixing holes, the jaw is in an opened or closed state under the condition that the inner sleeve moves, a slide way is arranged on the jaw, a tissue pad is arranged in the slide way, a groove is arranged on a clamping surface of the tissue pad and used for accommodating the cutter head and limiting the movement of the cutter head in the radial direction under the state that the jaw is closed.
According to the technical scheme of the embodiment of the disclosure, the tissue pad with the groove plays a role in blocking the movement of the cutter head in the radial direction, so that the risk of short circuit caused by contact between the cutter head and the jaw electrode is at least partially reduced, and the safety of the super-electric hybrid surgical operation is improved.
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, according to an embodiment of the present disclosure, jaws 124 are provided with a slide, and tissue pad 10 may be slid into the slide of jaws 124 and then secured. For example, jaws 124 can also be fitted with stops 1242. When the tissue pad 10 is installed, after the tissue pad 10 slides into the slideway of the jaw 124, the stop block 1242 is fixed at the entrance of the slideway to prevent the tissue pad 10 from sliding out, thereby playing a fixing role.
According to an embodiment of the present disclosure, the front section of jaw 124 is flanked by jaw electrodes 1243. 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, tissue pad 10 may be polytetrafluoroethylene. The friction coefficient of the material is small, so that the influence on the ultrasonic power output of the cutter head 1211 is small, and the cutter head is wear-resistant.
According to embodiments of the present disclosure, the stop 1242 may be a polyetheretherketone glass fiber reinforcement material, wherein the weight ratio of glass fibers is 20-40%. The polyetheretherketone glass fiber reinforced material is an insulating material, and can prevent the cutter head 1211 and the jaw electrode 1243 from being short-circuited by a stopper, compared with the polyetheretherketone carbon fiber reinforced material. Compared with polytetrafluoroethylene, the polyether-ether-ketone glass fiber reinforced material with the weight ratio of 20-40% of glass fiber has smaller friction coefficient, and plays a role in supporting the cutter head after the tissue pad is worn, so that the cutter head is prevented from being in contact with the tail end of the jaw to cause short circuit.
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 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, jaw 124 is secured to securing aperture 1231 by securing member 1246 (e.g., a claw) such that jaw 124 is rotatably coupled to inner sleeve 123. Surgical instrument 100 can further include a pin that passes through throughbore 1222 and second throughbore 1245 to rotatably couple jaw 124 with 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 in an opened or closed state to perform a surgical operation.
Fig. 6 schematically illustrates a schematic view of a jaw of an embodiment of the present disclosure.
As shown in fig. 6, the jaw 124 includes a jaw electrode 1243, a slideway 1244, and a stop mount 1245. Tissue pad 10 may be mounted to slide 1244, and then stop 1242 mounted at 1245 to prevent tissue pad 10 from sliding out.
Fig. 7 schematically illustrates a schematic view of a tissue pad of an embodiment of the present disclosure, and fig. 8 schematically illustrates a cross-sectional schematic view of a tissue pad of an embodiment of the present disclosure.
As shown in fig. 7 and 8, the clamping surface of tissue pad 10 is provided with grooves 11 for receiving knife head 1211 and limiting movement of knife head 1211 in a radial direction in the closed state of jaws 124. By means of the tissue pad with grooves, the movement of the cutting head in the radial direction is blocked, so that the risk of short-circuiting due to contact between the cutting head and the jaw electrodes is at least partially reduced, and the safety of the superelectric hybrid surgical operation is improved.
According to an embodiment of the present disclosure, the minimum wall thickness from the surface of the recess 11 to the left and right end surfaces of the tissue pad 10, i.e. the minimum thickness of the rim 13 of the tissue pad, is 0.2mm-0.3mm, preferably 0.20-0.25mm. The thickness can ensure that short circuit does not occur under the condition of not clamping tissues, and can ensure that discharge can be performed under the condition of clamping the tissues, thereby realizing the function of the electric knife.
According to an embodiment of the present disclosure, the maximum depth of the groove 11 is 0.3mm-0.6mm, for example 0.5mm. Therefore, the cutter head can be effectively prevented from sliding out from the side surface to contact the jaw electrode, and the safety is further improved.
In the embodiment of the present disclosure, as shown in fig. 8, the included angle α between the groove sidewall edge tangent and the groove bottom tangent may be greater than 80 degrees, for example, α may be a right angle. Therefore, the blocking effect of the side wall of the groove on the cutter head is enhanced, the cutter head is difficult to contact the jaw electrode due to radial vibration, and short circuit is avoided.
