[0002] This application claims the benefit of priority to U.S. Provisional Patent Application No. 63 / 065,958, filed on August 14, 2020, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure generally relates to medical devices that can be used to break up obstacles such as physiological stones or "pebbles" using lithotripsy.

[0004] More specifically, this disclosure relates to systems, apparatus, and methods for capturing stone fragments from a lithotripsy system. Background Technology

[0005] Medical endoscopes were first developed in the early 1800s and have been used to examine the inside of the body. A typical endoscope consists of a distal end with an optical or electronic imaging system and a proximal end with controls for manipulating tools and devices used to view the images, with a solid or tubular elongated shaft connecting the ends. Some endoscopes allow physicians to pass instruments or treatments along one or more hollow working channels, for example, to remove tissue or retrieve objects.

[0006] Over the past few decades, significant advancements have been made in the field of endoscopy, particularly in the fragmentation of physiological stones in the bile ducts, urethra, kidneys, and gallbladder. Physiological stones in these areas can obstruct ducts and cause significant pain for patients. Therefore, these stones are often fragmented for surgical removal or biotransmission. Various techniques and procedures have been developed to fragment stones, including ultrasonic lithotripsy, pneumatic lithotripsy, electro-hydraulic lithotripsy (EHL), and laser lithotripsy, which utilizes green light, YAG, or holmium lasers to break down the stones. Summary of the Invention

[0007] The inventors have recognized that, among other things, a problem to be solved in lithotripsy is the removal of stone fragments / clumps from the patient during or after the procedure. Typically, stone fragments are removed from the patient via suction applied to the distal end of a lithotripsy device. Suction pulls the stone fragments proximally through the suction tube and usually deposits the fragments, along with other fluids from the patient such as biofluids and irrigation fluids, into a waste container. Thus, stone fragments often comprise a portion of a mixture of materials located in a single container, making the removal of stone fragments difficult. It may be desirable to obtain stone fragments so that analysis can be performed. For example, a physician could observe the stone fragments to prescribe a diet to prevent future stone formation, or the stone fragments could be sent to a laboratory for detailed compositional analysis.

[0008] This subject matter provides a solution to this and other problems by offering a stone fragment capture system that collects stone fragments separately from other collected materials, such as waste fluid. The stone fragment capture system disclosed herein can retrieve stone fragments from a stream of material removed from a patient via aspiration. The stone fragments can be retained in a container that can hold fragments pre-separated from the waste fluid for later retrieval and analysis. In an example, the stone fragments can be stored in a sealed container for transport to a laboratory without user intervention or repackaging.

[0009] The inventors have recognized that, among other things, a problem to be addressed in lithotripsy is the possibility of the lithotripsy device becoming clogged with stones or stone fragments. If this occurs, it may lead to surgical interruption, requiring the device to be disassembled to clear the blockage. For example, the system may be shut down, and the device may be disconnected, disassembled, cleaned, and reassembled, resulting in increased frustration and surgical length, as well as associated costs associated with prolonged surgical time.

[0010] This topic offers a solution to this and other problems by incorporating a vacuum port into an accessory for a lithotripsy apparatus. This vacuum port allows for the removal of blockages within the lithotripsy apparatus without disassembling the apparatus or shutting down the system. The vacuum port provides a sealable access port to the lithotripsy apparatus, allowing the insertion of instruments to clear the blockage without interrupting the lithotripsy system, thereby reducing downtime and frustration associated with disassembly and reassembly. In this example, the vacuum port accessory can be integrated into a stone fragment capture system.

[0011] In an example, a lithotripsy device may include: a handheld component; a lithotripsy probe extending from the handheld component; an energy source coupled to the handheld component and configured to deliver energy to a distal end of the lithotripsy probe; a suction passage extending from the distal end of the probe and through the handheld component; and a capture device coupled to the handheld component, the capture device including a container and a capture element, the container including a storage space within the container, an inlet port configured to be coupled to the handheld component at the suction passage, and an outlet port, the capture element being coupled to the container and configured to facilitate the capture of stone fragments within the storage space.

[0012] In another example, a method for obtaining stone fragments via lithotripsy may include: breaking the stone using a lithotripsy device; drawing a vacuum through the lithotripsy device to pull the stone fragments and waste liquid through the lithotripsy device; drawing the vacuum through a stone trapping device connected to the lithotripsy device; depositing the stone fragments within the stone trapping device using a trapping element; and continuing to draw a vacuum to deposit the waste liquid in a waste container.

[0013] In other examples, a capture device for collecting fragments generated during lithotripsy may include: a container including a wall defining a storage space within the container, an inlet port coupled to the wall and configured to be coupled to a handpiece at a suction passage, and an outlet port coupled to the wall; a capture element coupled to the container and configured to facilitate capturing stone fragments within the storage space; and a connector for connecting the container to a handpiece of the lithotripsy device.

[0033] This disclosure provides examples of apparatus, systems, and methods that can help solve problems associated with breaking up stones and collecting stone fragments during lithotripsy procedures. In particular, this disclosure provides examples of apparatus, systems, and methods that can be used to obtain stone fragments through a collection process for later analysis. Typically, collecting stone fragments for later analysis can be challenging because they are collected simultaneously with other surgical fluids, thus requiring subsequent processing such as separation and repackaging. The benefits of the methods described herein include, among others, the separate capture of stones from the waste fluid in a container, thereby reducing post-processing procedures and time. The stone fragments can thus be pre-separated from the waste fluid and stored in a container that can be used to store or transport the stone fragments. Furthermore, the stone fragment capture apparatus described herein may include a vacuum port that allows access to clear the lithotripsy apparatus without disassembling it.

[0034] Figure 1 An isometric view of an example lithotripsy system 100 is illustrated, which includes a lithotripter 102 having a housing 104, such as a handle. The lithotripter 102 may include a delivery member 106 capable of being delivered to the treatment site through the working channel WC of an endoscope E. The endoscope E may also include a light source LS and a camera C.

[0035] The delivery member 106 may include a flexible or rigid elongated shaft 108 having a tubular structure. Suitable materials for the delivery member include, but are not limited to, polytetrafluoroethylene (“PTFE”), polyethylene (“PE”), and polyamide. The elongated shaft 108 may include an outer surface 110 and at least one lumen 112 extending through the elongated shaft 108, the lumen being adapted for the passage of components and materials in communication with the end effector described herein.

[0036] The delivery member 106 may include, at its distal end, an end effector, such as probe 114, capable of delivery to the treatment site. Probe 114 may be configured to deliver energy to fragment moving stones, such as those located in the bile duct, urethra, kidney, or gallbladder. Probe 114 of the lithotripter 102 may be introduced into the patient through the working channel WC of an endoscope E or similar instrument, driven by the delivery member 106. Probe 114 may be flexible or rigid.

[0037] The stone crusher 102 can be connected to a signal generator 116. The signal generator 116 may include a power supply 118 or be connectable to an external power source. The signal generator 116 may also include an input device 120 for receiving instructions from an operator, and may include a controller 122 with processing circuitry for determining actions based on operator input and for sending control signals via an output device 124 to communicate with the stone crusher 102. The signal generator 116 can generate and send signals to a probe 114 of the stone crusher 102 to cause the probe 114 to emit acoustic energy. The acoustic energy may include sound waves, ultrasonic waves, or shock waves, or any combination thereof. The acoustic energy can be delivered to the stones S to damage, break, and thereby split the stones S. Examples herein are described with reference to a combination of ultrasonic and shock wave applications, but any suitable acoustic energy or combination thereof may be provided for splitting stones. The terms “acoustic” and “ultrasonic” are used interchangeably herein and may include any suitable acoustic energy for breaking stones.

[0038] The features of probe 114 can provide improved fragmentation of the stone S. For example, probe 114 may include a drill 126 (which does not necessarily include a rotary drill bit), such as an ultrasonic drill that emits acoustic energy in the longitudinal direction A1 to drill a hole in the stone. Probe 114 may also include one or more transverse emitters 128, such as transverse ultrasonic transducers, to deliver acoustic energy within the hole, thereby fragmenting the stone from the inside out.

[0039] Drill 126 can be coupled to elongated shaft 108 and can be located at the distal tip of probe 114. Drill 126 may include at least a portion extending distal to the elongated shaft 108. Figure 1 In the example, drill 126 can be configured to emit ultrasonic energy in the longitudinal direction A1. Drill 126 can cause mechanical alteration or damage to the stone S by generating pulsating shock waves that move approximately along the longitudinal direction A1. Drill 126 can be configured to drill holes, such as into recesses in the stone S or through passages P in the stone S. Figure 1 An example is shown, including drill 126 which has already drilled through the stone S to make way for passage P.

[0040] Drill 126 may be an ultrasonic transmitter that receives ultrasonic energy from a remotely positioned ultrasonic transducer 136. For clarity in comparison to other transmitters and transducers in this disclosure, this ultrasonic transducer will be referred to as drill transducer 136. Drill transducer 136 may be located within a housing 104 of, for example, a lithotripter 102. Drill transducer 136 may transmit ultrasonic energy distally out of housing 104 in a generally longitudinal direction A1. Ultrasonic energy may be transmitted from drill transducer 136 to drill 126 via ultrasonic transmission member 138. Ultrasonic transmission member 138 may be coupled to drill transducer 136 at a proximal end and to drill 126 at a distal end. Ultrasonic transmission member 138 may be formed of any material capable of transmitting ultrasonic energy from drill transducer 136 to drill 126, including but not limited to metals, metal alloys, shape memory alloys, polymers, ceramics, fibers, crystals, or composites thereof.

[0041] Drill transducer 136 can be electrically connected to signal generator 116, for example, via connector 140, to receive signals for operating drill 126. Drill transducer 136 can be actuated, for example, by an operator pressing a foot pedal 132 electrically connected to signal generator 116, or by a drill actuator 134 connected to housing 104 electrically connected to signal generator 116. Alternatively or additionally, drill transducer 136 can be operated by an operator based on actions determined by input device 120 and / or controller 122. Any other suitable actuator for controlling the initiation of drill 126 can be provided.

[0042] Although Drill 126 is described as an ultrasonic drill, in some examples, other types of drills may be provided, including but not limited to motor-operated rotary drills. Like... Figure 1 Similar to the drill transducer in the example, the motor can be positioned remotely from the probe 114, such as within the housing 104, and the motor can be coupled to the drill 126 via a rotary transmission member. In other words, regarding... Figure 1 In a variation of the example, a rotary motor may be provided instead of the drill transducer 136, and a rotary transmission member may be provided instead of the ultrasonic transmission member 138.

[0043] In addition to using an ultrasonic transmitter for drilling, probe 114 may include at least one radial or transverse ultrasonic transmitter 128 configured to direct ultrasonic energy outward in the radial or transverse direction A2 and away from the longitudinal direction A1, for example, toward the inner surface (pathway P) of the stone S. Figure 1 In one example, at least one transverse ultrasound transmitter 128 includes a plurality of transverse ultrasound transmitters 128 or an array of transverse ultrasound transmitters 128.

[0044] Each of the transverse ultrasound transmitters 128 can direct ultrasound energy in the transverse direction A2, wherein each of the transverse ultrasound transmitters 128 is positioned along a different longitudinal position on the probe 114. In some examples, the transverse ultrasound transmitters 128 can be spaced apart along the longitudinal direction A1. The transverse ultrasound transmitters 128 can extend transversely or radially around the probe 114. In some examples, the transverse ultrasound transmitters 128 can extend around the entire 360-degree circumference of the probe 114, or when the probe has a non-circular cross-section in a direction transverse or perpendicular to the longitudinal direction A1, the transverse ultrasound transmitters 128 can extend around the periphery of the probe 114. In other examples, the transverse ultrasound transmitters 128 can only partially surround the probe 114.

[0045] A transverse ultrasonic transmitter 128 can be located near the end of the drill 126. The advantage of this arrangement is that the transverse ultrasonic transmitter 128 can follow the drill 126, allowing it to advance through the passage P after the drill 126 has prepared a path P within the stone S. When the transverse ultrasonic transmitter 128 is activated, for example by a transverse transmitter actuator 142 electrically connected to it via an electrical element 144 such as a wire, the transverse ultrasonic transmitter 128 can be configured to emit ultrasonic energy into the passage P and into the interior of the stone S, causing the stone S to split from within.

[0046] Similar to the drill transducer 136, the transverse ultrasonic transmitter 128 may include an ultrasonic transducer or other acoustic transducer. An electro-acoustic transducer is a component that can convert an electrical signal into a variant of a physical quantity such as sound waves or pressure. An ultrasonic transducer may include a linear piezoelectric stack having a piezoelectric element located between two metal plates. In other examples, a magnetically confined stack may be used. Such a piezoelectric element can convert electrical energy (e.g., electric current) into mechanical energy (e.g., sound waves, acoustic waves, ultrasonic waves, shock waves). The piezoelectric element may include a crystal, such as quartz, with physical properties that cause the crystal to undergo mechanical stress when subjected to an electric field that causes the crystal to change size or shape. The piezoelectric element alternately expands and contracts in response to an alternating electric field, which may be provided, for example, by a signal generator 116. This expansion and contraction can generate sound waves that can be delivered to a stone S to cause the stone S to split.

[0047] To help position the stone S relatively stationary relative to the working channel WC of the endoscope E and relatively stationary relative to the probe 114 during drilling (except for the longitudinal movement of the probe through the stone A1), suction can be applied through the working channel WC, as indicated by suction arrow 130. Suction 130 can "capture" the stone S by pulling it toward the working channel WC and thus toward the drill 126 used for drilling the probe 114. As the stone S breaks, fragments of the stone can be suctioned into the working channel WC.

[0048] Some lithotripsy systems described herein may include a fluid input device 166 for receiving fluid from a fluid reservoir FS and delivering the fluid to the treatment site. For example, irrigation or flushing fluid may be transferred via an endoscope E or an elongated shaft 108. Typical stone fragment recovery systems involve simply collecting a mixture of solids and fluids obtained from the patient during the procedure. For example, aspiration 130 may be applied at the distal end of the endoscope E or elongated shaft 108, and a vacuum may be created through the endoscope E or elongated shaft 108 to deposit materials such as stone fragments and waste fluid into a waste container. In the example, tubing 150 may be connected to housing 104 to fluidly connect the lumen extending through the working channel WC of the endoscope E to a collection container 152. Tube 150 may also be connected to a suction device 154 or a pump to create a vacuum through the working channel WC, indicated by suction arrow 130.

[0049] Figure 2 This is a perspective view of a lithotripsy system 200 including a handheld probe 202 configured to deliver high-frequency ultrasonic energy to break up stones. In this example, the lithotripsy system 200 may include an oscillating lithotripter as described in US Patent No. 9,974,552 entitled "Oscillating Lithotripter" by St. George et al., assigned to Gyrus ACMI, Inc., the entire contents of which are incorporated herein by reference.

[0050] The handheld probe 202 may include a handheld component or handle 204 and a shaft 206. The handheld probe 202 may be connected to the generator 208, for example, via a cable 210. The collection tube 212 may be connected to a storage container, such as a fluid storage tank FS. Figure 1 This is for collecting fluids and other biological materials collected via shaft 206. Shaft 206 may extend from proximal end 214 to distal end 216 and may include an internal lumen (e.g., Figure 17 (The lumen 532). The handle 204 may also include buttons 218A and 218B for controlling the activation of energy and a knob 220 for controlling the suction level.

[0051] Handle 204 may include any means suitable for facilitating the manipulation and operation of shaft 206. Handle 204 may be located at the proximal end 214 of shaft 206 or at another suitable location along shaft 206. In examples, handle 204 may include a gun grip, a knob, a handlebar grip, etc. In addition to or in place of buttons 218A and 218B and knob 220, handle 204 may include one or more of buttons, triggers, levers, knobs, control panels, etc., for controlling energy activation, suction, flushing, etc.

[0052] In various examples, the distal end 216 of shaft 206 or another suitable location along shaft 16 may include a surgical device that may include components or means for interacting with a patient, such as those configured to cut and cauterize tissue and / or produce the patient's desired tissue effect. In examples, surgical tools may include forceps, cutting tools, ablation electrodes, cryogenic needles or applicators, ultrasonic probe tips, and combinations thereof. Thus, the handheld probe 202 may be equipped with linkages such as mechanical linkages for actuating forceps or cutting tools, electrical linkages for activating ablation electrodes, acoustic linkages; fluid conduits (e.g., for delivery of cryogenic argon), and combinations thereof. In examples, the surgical device may be included on a device used in conjunction with the handheld probe 202. In other examples, the handheld probe 202 may include devices for observing the patient, such as or combined with an optical device including an endoscope (e.g., endoscope E above) and a fiberscope.

[0053] Generator 208 may include an energy source for the handheld probe 202. For example, generator 208 may be configured to provide electrical power for performing ablation and cauterization functions and / or ultrasonic energy for providing cutting, coagulation, fragmentation, or other types of surgical functions. In this example, generator 208 may provide ultrasonic energy, while intermittent ballistic shock wave energy may be provided via an oscillating free block within handle 204.

[0054] Shaft 206 may include an elongated member configured to deliver energy for breaking up stones into the patient's body. Shaft 206 may be rigid and formed of a metallic or plastic material. In an example, shaft 206 may be sized for use in conjunction with an endoscope to perform lithotripsy. Thus, shaft 206 can be inserted into an incision in the patient's epidermis, through the patient's body cavity, and into an organ. Therefore, it is desirable that the diameter or cross-sectional shape of shaft 206 be as small as possible to facilitate minimally invasive surgery. However, shaft 206 may also incorporate a lumen (e.g., Figure 17The lumen 532 is designed to allow for the removal of fragments of the stone generated by the fragmentation energy, for example, via suction. Thus, the dimensions of the shaft 206 and the lumen extending through it must be balanced to allow for minimally invasive procedures and adequate removal of stone fragments. For example, a lumen that is too small will increase the time required to break the stone into appropriately small pieces.

[0055] Figure 1 Stonecrushing Technique 100 and Figure 2 The lithotripsy system 200 is an example of a lithotripsy system that can be used with the stone fragment capture device, system, and method described herein. For example, a stone fragment capture device can be connected to housing 104 and tube 150 to collect stone fragments obtained by lithotripter 102 and facilitate the clearing of any blockages that may form in lithotripter 102. Similarly, the stone fragment capture device of this disclosure can be connected to handle 204 and tube 212. Although this application is described with reference to a lithotripsy system for obtaining stones, other types of surgical and endoscopic devices can also be used with the stone fragment capture system and method disclosed herein. For example, any surgical device that can be configured for insertion into a patient involving the aspiration of biological material and waste fluid can benefit from this disclosure, such as forceps intended for removing endometrial tissue from the uterus. Examples of surgical devices that can be used with this disclosure may utilize various energy sources such as laser energy, ultrasonic energy, etc., to break, fragment, and / or pulverize particles such as pebbles and other solid or rigid bodies, and may remove these particles after they have been broken, for example by using a vacuum to pull solids, liquids, and mixtures into a designated collection receiving portion.

[0056] Figure 3 It is used with Figure 2 A schematic cross-sectional view of a stone fragment capture system 250 used in conjunction with a stone crushing system 252. The stone crushing system 252 can be used with... Figure 1 The lithotripsy system 100 that can deliver fragmentation energy radially along the probe 114 and Figure 2 This can be used in conjunction with a stone fragmentation system 200 that delivers fragmentation energy longitudinally along axis 206. The stone fragment capture system 250 may include a valve 254 and a filter 256, which may be coupled to a container 258. The container 258 may include a housing 260, a cover 262, an inlet port 264, an outlet port 266, and a baffle 267.

[0057] The stone fragmentation system 252 may include any of the lithotripsy systems described herein or another surgical system configured to generate suction therethrough. The stone fragmentation system 252 may include a handle 268 and a stem 270. In an example, the handle 268 may include a design similar to... Figure 2The knob 220 and knob 272 control the function of the stone crushing system 252, such as the suction level. The passage 274 may be configured to extend from the handle 268, such as from a shaft or probe extending distally from the handle 268, and extend through the knob 272 and the stem 270 located at the proximal end.

[0058] Container 258 can be coupled to handle 268 and tube 276. Housing 260 can be positioned such that inlet port 264 is coupled to stem 270. Stem 270 may include barbs 278 configured to facilitate attachment of container 258 to handle 268. For example, barbs 278 may be resilient edges extending around stem 270, having a diameter slightly larger than the inner diameter of stem inlet port 264. Inlet port 264 may include a cylindrical tube extending from base plate 280 of housing 260. The tube forming inlet port 264 may taper to slow the movement of debris 284 into container 258. Base plate 280 may include an annular disc connecting inlet port 264 to housing 260. Similarly, outlet port 266 may include a cylindrical tube extending from cap 262. Cap 262 may include end plate 282, which may include an annular disc connecting outlet port 266 to cap 262. The cap 262 can be attached to the housing 260 by any suitable means, such as a threaded connection or a snap-fit ​​connection. In the example, the tube 276 can be integrated with the outlet port 266, as shown. In other examples, the tube 276 can be attached to the outlet port 266 via a barbed connector similar to a barb 278. Although the illustrated example shows the container 258 directly attached to the stem 270 of the handle 268, the container 258 can, for example, be additionally attached to the handle 268 via a tube of a length that can surround the stem 270 and be inserted into the inlet port 264.

[0059] Container 258 can be positioned between handle 268 and tube 276 to capture stone fragments 284 exiting passage 274. Inlet port 264 can be configured to align with outlet port 266 along axis A3. However, in other examples, outlet port 266 can be offset relative to axis A3, as shown below. Figure 15 and Figure 16As discussed, stone fragments 284 can flow from handle 268 to stem 270 through passage 274. Stone fragments 284 can be dispersed into the interior of container 258, for example, by using a capturing element comprising one or more tubes having an inlet port 264, a baffle 267, and a filter 256. For example, stone fragments 284 can fall to base plate 280 by gravity. In an example, housing 260 can extend beyond tip 286 of inlet port 264 to provide a gap for stone fragments 284 to enter container 258. In an example, end plate 282 can be positioned at a distance from tip 286 to allow momentum dissipation of stone fragments 284. Furthermore, baffle 267 can be positioned opposite tip 286 to deflect fragments 284 into housing 260. Baffle 267 may include a body of various shapes extending radially inward from the wall of housing 260 or axially outward from inlet port 264 to prevent outlet port 266 from directly impacting fragment 284. Baffle 267 may reduce the momentum of fragment 284 to facilitate the removal of fragment 284 from the suction path, such as the path of flowing liquid, between inlet port 264 and outlet port 266.

[0060] Filter 256 can be positioned within container 258 to prevent stone fragments 284 from escaping from container 258. In the illustrated example, filter 256 is positioned within outlet port 266. However, filter 256 can be positioned anywhere within container 258 to prevent material from freely entering outlet port 266. In the example, filter 256 can be mounted to cap 262 to allow access to stone fragments 284 within container 258 when cap 262 is removed. However, filter 256 can be configured to be removed from housing 260 independently of cap 262. Filter 256 can be sized to allow liquids and small pieces of tissue or stone fragments and other debris to pass through container 258, but this prevents large pieces of material from being retained within container 258. The trapping element described herein, filter 256 described herein, and other filter or orifice elements (e.g., Figure 8A and Figure 8B The flow restrictor valve (360) can be sized to retain material blocks or stone fragments suitable for further analysis, such as visual observation for color and texture analysis.

[0061] Valve 254 may be positioned near the tip 286 of stem 270 and may be used to intermittently close stem 270 to prevent stone fragments 284 from leaving container 258. For example, valve 254 may close to prevent stone fragments 284 from leaving container 258 at inlet port 264 when container 258 is removed from inlet port 264 and tube 276 is removed from cap 262. Valve 254 may include any suitable means for allowing flow into housing 260 when container 258 is attached to stem 270 and for preventing stone fragments from leaving housing 260 when container 258 is separated from handle 268. Valve 254 may be configured to be mechanically opened by engagement with stem 270 or by being pulled through container 258 by vacuum. See reference Figure 4A and Figure 4B The valve 254 discussed may include a bias stop.

[0062] Figure 4A It is used with Figure 3 A side perspective view of a first example of a valve 254 used with a stone fragment capture system 250. In the illustrated example, valve 254 may include a stop 290, a resilient element 292, a stop 294, supports 296A to 296H, and a support ring 298. Figure 4B The section cut at section 4B-4B is used to show the support struts 296A to 296H. Figure 4A A cross-sectional view of valve 254. Simultaneously, regarding... Figure 4A and Figure 4BThe following discussion is provided. Supports 296A to 296H may be connected at a first end to a ring 298 and at a second end to a stop 294. The support ring 298 may be positioned around the stem portion 270 such that the stop 294 is positioned opposite the opening of the inlet port 264 connected to the passage 274. The support ring 298 may be fastened to the inlet port 264 using any suitable means such as adhesive, fasteners, or threads. Supports 296A to 296H may be used to guide the stop 290 to engage with and away from the tip 286. The stop 290 may include a circular or rectangular shape, or any suitable shape for closing the inlet port 264. The stop 290 may include a hole or notch for sliding along the supports 296A to 296H, or the stop 290 may simply be guided between the supports 296A to 296H. When the stone crushing system 252 is not in operation, the elastic element 292 can be pushed against the stop 294 to push the stop 290 against the inlet port 264. This prevents or inhibits material from leaving and entering the container 258. When the stone crushing system 252 is in operation, a vacuum can be drawn from the pipe 276 to push the stop 290 away from the tip 286. This allows stone fragments 284 to flow out from the inlet port 264 and flow between the supports 296A and 296H into the container 258.

[0063] Figure 5 This is a schematic cross-sectional view of a stone fragment capture system 300 for use with a stone crushing system 252. The stone fragment capture system 300 may include a valve 304 and a filter 306, which may be coupled to a container 308. The container 308 may include a housing 310, a cover 312, an inlet 314, and an outlet 316.

[0064] The stone fragment capture system 300 can be used in conjunction with the stone fragmentation system described herein, such as with the stone fragmentation system 252 and other lithotripsy systems or another surgical system configured to generate suction through it. For example, inlet 314 can be connected to stem 270, such that passage 274 can be connected to the interior of housing 310.

[0065] Container 308 can be connected to handle 268 ( Figure 3 ) and pipe 276 ( Figure 3The housing 310 can be positioned such that the inlet 314 is coupled to the stem 270. The inlet 314 may include a cylindrical opening extending through a base plate 330 of the housing 310. The inlet 314 may include an elastic material having an opening slightly smaller than the diameter of the stem 270, allowing for a tight seal between the inlet and the stem 270. The base plate 330 may include an annular disc or polygonal plate connecting the inlet 314 to the housing 310. Similarly, the outlet 316 may include a cylindrical tube extending from the cap 312. The cap 312 may include an end plate 332, which may include an annular disc connecting the outlet 316 to the cap 312. The cap 312 may be coupled to the housing 310 by any suitable means, such as a threaded connection or a snap-fit ​​connection. In one example, the tube 276 may be integral with the outlet 316. In other examples, the tube 276 ( Figure 3 It can be accessed via something similar to barb 278 ( Figure 3 The container 308 is connected to the outlet 316 via a barbed connector. Although the illustrated example shows the container 308 directly connected to the stem 270 of the handle 268, the container 308 may also be connected to the handle 268 via a tube of a certain length, which may be connected around the stem 270 and inserted into the inlet 314.

[0066] Container 308 can be positioned between handle 268 and tube 276 to capture stone fragments 334 exiting passage 274. Inlet 314 can be configured to align with outlet 316 along axis A4. However, in other examples, outlet 316 can be offset relative to axis A4, as shown below. Figure 15 and Figure 16 As discussed, gravel fragments 334 can flow from handle 268 to stem 270 through passage 274. Gravel fragments 334 can be dispersed into the interior of container 308. For example, gravel fragments 334 can fall to base plate 330 by gravity. In an example, shell 310 can extend beyond tip 336 of stem 270 to provide a gap for gravel fragments 334 to enter container 308. In an example, end plate 332 can be positioned at a distance from tip 336 to allow momentum dissipation of gravel fragments 334. Container 308 can be configured as referenced. Figure 3 The described capturing elements include, for example, an elongated tube extending from inlet 314 and a baffle similar to baffle 267.

[0067] Valve 304 may be positioned near the tip 336 of stem 270 and may be used to intermittently close stem 270 to prevent stone fragments 334 from leaving container 308. Valve 304 may include any suitable means for allowing flow into housing 310 when container 308 is attached to stem 270 and for preventing stone fragments from leaving housing 310 when container 308 is separated from handle 268. In the illustrated embodiment, valve 304 may include a baffle valve having a stop 338, a resilient element 340, and a sidewall 342. Sidewall 342 may include a cylindrical body or a tube having another cross-sectional shape for surrounding stem 270. Stop 338 may be pivotally coupled to sidewall 342 at coupling 344, which may include a pinned coupling. Thus, the stop 338 can rotate about the engagement member 344 between the engagement sidewall 342 and the central axis positioned generally parallel to the stem portion 270. The resilient element 340 can bias the stop 338 into a closed position engaged with the sidewall 342. The resilient element 340 may include a spring, such as a disc spring that can simultaneously actuate against both the sidewall 342 and the stop 338. The valve 304 can be configured to open when material flows through the container 308, for example, when a vacuum is drawn from the outlet 316.

[0068] For reference Figures 6A to 7C In more detail, filter 306 may be positioned within container 308 to prevent gravel fragments 334 from exiting container 308. Filter 306 may include a flow-limiting valve that can be adjusted to change the size of the gravel fragments 334 that may allow flow through the gravel fragment capture system 300. For example, filter 306 may include opposing mesh layers 346A and 346B, the relative positions of which can be changed to adjust the radial gap size between the mesh elements.

[0069] Figure 6A and Figure 6B This is a schematic perspective view of filter 306, which includes components suitable for use with... Figure 5The flow-limiting valve is used in conjunction with the stone fragment capture system 500 and other systems described herein. The filter 306 may include opposing mesh layers 346A and 346B. The mesh elements in each of layers 346A and 346B may be oriented parallel to each other. For example, layer 346A may include mesh strands 348A to 348D, and layer 346B may include strands 350A to 350D. Layers 346A and 346B are described as each having four parallel mesh strands, but layers 346A and 346B may include any suitable number of strands to filter or inhibit the flow of biological material. Strands 348A to 348D may be mounted to frame 352, and strands 350A to 350D may be mounted to frame 354. Frames 352 and 354 may be connected by a support post 356, allowing frames 352 and 354 to rotate relative to each other. One of frames 352 and 354 may be coupled to a handle 358. like Figure 6A As shown, strands 348A to 348D and strands 350A to 350D are parallel to each other in a horizontal position (relative to each other). Figure 6A (orientation). Figure 6B In the middle, frame 352 rotates counterclockwise relative to frame 354 via handle 358, so that strands 350A to 350D are in a vertical position perpendicular to strands 348A to 348D (relative to...). Figure 6B (orientation).

[0070] Figures 7A to 7C Schematic top views of the mesh layers 346A and 346B, including filter 306, during alignment—lateral alignment and vertical alignment. Thus, the radial spacing between the strands (e.g., relative to the central axis of frame 354) arranges strands 348A to 348D and strands 350A to 350D in large, medium, and small spacing configurations.

[0071] exist Figure 7A In the middle, strands 348A to 348D and strands 350A to 350D are parallel to each other in the vertical position (relative to each other). Figure 7A (orientation). Thus, the interval S1 measured radially relative to the center of frame 354 is the maximum value of the interval. Figure 7B In the middle, the strands 3450A to 350D are relative to Figure 7A Rotate clockwise by approximately 45 degrees. This results in the interval S2, measured radially relative to the center of frame 354, being smaller than S1.

[0072] exist Figure 7C In the middle, the strands 3450A to 350D are relative to Figure 7A Rotate clockwise by approximately ninety degrees. Thus, the radial interval S3 measured relative to the center of frame 354 is smaller than S2 and is the minimum value of the interval.

[0073] Mesh layers 346A and 346B can be manually adjusted by the user of the stone fragment capture system 500 to control the size of the stone fragments desired to be captured by container 308. For example, mesh layers 346A and 346B can be adjusted to... Figure 7A The location is chosen to collect large fragments, which can be useful, for example, when only a small number of fragments are expected for laboratory analysis. However, the mesh layers 346A and 346B can be adjusted to... Figure 7C The location is chosen to collect only small fragments, which can be useful, for example, when a large number of fragments are expected to be used for visual inspection.

[0074] Figure 8A and Figure 8B It is applicable to and Figure 5 A schematic top view of a flow restrictor valve 360 ​​used in conjunction with a stone fragment capture system 300. The flow restrictor valve 360 ​​may include an iris valve having slit plates 362A to 362G. Figure 8A The gap filler plates 362A to 362G in a closed configuration are shown, and Figure 8B The sump pieces 362A to 362G are shown in an open configuration. The sump pieces 362A to 362G can be constrained by a frame 364. A control lever 366 can be connected to the frame 364 to move the sump pieces 362A to 362G between an open position and a closed position. Figure 8A As shown, the septum slabs 362A to 362G can be positioned to make the orifice 368 smaller. Therefore, the flow restrictor 360 can be configured to minimize the amount of biomaterial passing through the container 308, thereby reducing the size of the stone fragments retained in the container 308. Figure 8B As shown, the septum slabs 362A to 362G can be positioned to make the orifice 368 larger. Therefore, the flow restrictor 360 can be configured to maximize the amount of biomaterial passing through the container 308, thereby increasing the size of the stone fragments retained in the container 308. Therefore, Figure 5 The operator of the stone fragment capture system 500 can, for example, adjust the flow restrictor valve 360 ​​to the desired size of stone fragments to be retained by the container 308. The filler plates 362A to 362G can be configured to operate as understood by those skilled in the art, for example by being pinned to and connected to an outer diameter actuation mechanism near the outer diameter end of the frame 36, which causes each of the filler plates 362A to 362G to rotate simultaneously at the pinned connection. In the example, the flow restrictor valve 360 ​​can be constructed similarly to an iris shutter used in a camera, enlarged in size and robustness for use as a flow control orifice in a pressurized environment.

[0075] Figure 9This is a schematic cross-sectional view of a stone fragment capture system 400 for use with stone crushing system 252 and other systems described herein. The stone fragment capture system 400 may include a frame 402 and a cylinder 403. The frame 402 may include stems 404A and 404B, barbs 406A and 406B, a first valve 408A, and a second valve 408B. The cylinder 403 may include a housing 410 and a filter 412.

[0076] The stone fragment capture system 400 can be connected to tubes 414A and 414B. Stem 404A can be configured to align with stem 404B along axis A5. However, in other examples, stem 404B can be offset relative to axis A5, as shown below. Figure 15 and Figure 16 The tube 414A can be connected to a shredding tool, such as handle 252. The tube 414B can be connected to a waste collection container and a vacuum generator, such as a pump.

[0077] The stone fragment capture system 300 can be used in conjunction with stone fragmentation systems described herein, such as stone fragmentation system 252, and other lithotripsy systems. For example, inlet 314 can be connected to stem 270, allowing passageway 274 to connect to the interior of housing 310.

[0078] The stone fragment capture system 300 can be configured such that a rack 402 can remain connected to pipes 414A and 414B, and one or more cylinders 403 can be sequentially connected to the rack 402. Furthermore, each cylinder 403 may include a self-sealing system, such that upon removal from the rack 402, each cylinder 403 is ready to be transported or conveyed to a different location for storage and analysis. For example, valves 408A and 408B can be configured to open and close during insertion and removal of cylinders 403 from the rack 402, as described in reference. Figures 11 to 14 The subject of discussion.

[0079] The frame 402 and cylinder 403 can be configured for use with different systems or to collect gravel fragments of different sizes. For example, the frame 402 may include stems 404A and 404B of different sizes, such that tubes 414A and 414B of different sizes can be connected to stems 404A and 404B. Furthermore, the cylinder 403 can be configured with filters 412 of different grades. Filters 412 may additionally include... Figure 5 Filter 306 or Figure 8A and Figure 8B The flow-limiting valve 360. In this way, the stone fragment capture system 300 can be configured to allow stone fragments of different sizes to pass through the stone fragment capture system.

[0080] In the example, valves 408A and 408B may be attached to cylinder 403 and may be configured to open by engaging actuators attached to cylinder 402 when cylinder 403 is inserted into frame 402.

[0081] In the example, valves 408A and 408B can be attached to frame 402 and can be configured to open by engaging actuators attached to frame 402 when cylinder 403 is inserted into frame 402, such as... Figure 12 As shown in the image.

[0082] Figure 10 yes Figure 9 A schematic cross-sectional view of a frame 402, wherein cylinder 403 is removed. The frame 402 may be configured as a body to readily receive cylinder 403, allowing flow through cylinder 403 when it is seated within the frame 402, and allowing flow around the space for cylinder 403 when cylinder 403 is removed from the frame 402. The frame 402 may include a housing 432 having a socket 432, an internal passage 434, and valves 408A and 408B. Cylinder 403 may include actuators 436A and 436B. In an example, the frame 402 may include a semi-cylindrical member.

[0083] When the cylinder 403 is not located in the socket 432, valves 408A and 408B can be configured to guide flow from the stem 404A, through valve 408A, through the internal passage 435, through valve 408B, and into the stem 404B. When the cylinder 403 is located in the socket 432, valves 408A and 408B can be configured to guide flow from the stem 404A, through valve 408A, through the cylinder 403, through valve 408B, and into the stem 404B.

[0084] Figure 11 This is a schematic cross-sectional view of a valve 408B in a frame 402 configured to interact with an actuator 436B of a cylinder 403. The valve 408B may include a flap 438 and a hinge 440. Figures 12 to 14 As shown, flap 438 can be biased toward housing 432. Cylinder 403 can be fitted into socket 432 of frame 402 such that actuator 436b abuts against valve 408B. Actuator 436B can overcome the bias applied to flap 438 by the biasing device. Therefore, flow can be allowed from inside cylinder 403 through valve 408B. When flap 438 is closed, fluid can flow freely from internal passage 435 to stem 404B. When flap 438 is open, flap 438 can close internal passage 435, allowing fluid to flow freely from cylinder 403 to stem 404B.

[0085] Figure 12 , Figure 13 and Figure 14 Including applicable as Figure 11 A schematic diagram of the spring valve 440, pressure valve 442, and motor valve 444 used in valve 408B.

[0086] like Figure 12 As shown, the spring valve 440 may include a flap 438 connected at the hinge 440 to the housing 432, wherein the flap 438 is biased by a spring 446. The spring 446 may be configured to push the flap 438 against the frame 402 to block flow through the cylinder 403 and allow flow through the internal passage 435. An actuator 436B may be configured to engage the flap 438 to push the flap 438 away from the frame 402.

[0087] like Figure 13 As shown, pressure valve 442 may include rod 448A, damper 450, and rod 448B. Rod 448A may be attached to flap 438 at hinge 452A, and rod 448B may be attached to housing 432 at hinge 452B. Damper 450 may be configured to push flap 438 against frame 402 to prevent flow through cylinder 403 and allow flow through internal passage 435. Actuator 436B may be configured to engage flap 438 to push flap 438 away from frame 402.

[0088] like Figure 14 As shown, the motorized valve 444 may include a motor 454, which may be connected to the flap 438 via a linkage 456. In other examples, the motor 454 may serve as a hinge 440 and may be directly coupled to the flap 438. The motor 454 may be configured to push the flap 438 against the frame 402 to block flow through the cylinder 403 and allow flow through the internal passage 435. The actuator 436B may be configured to engage the flap 438 to push the flap 438 away from the frame 402.

[0089] Figure 15 This is a schematic cross-sectional view of a stone fragment capture system 500 for use with stone crushing system 252 and other systems described herein. Stone crushing system 252 may include any of the lithotripsy systems described herein and may include a handle 204 and a shaft 206. Stone fragment capture system 500 may include a stone capture device 502 having a vacuum port 504. Stone capture device 502 may include a housing 506 including an upper component 508A, a lower component 508B, and a connector 510. Figure 16 yes Figure 15 A schematic top view of the stone-catching device 502, showing the position of the pipe connector 512 relative to the connector 510. Meanwhile, for... Figure 15 and Figure 16Let's have a discussion.

[0090] The stone fragment capture system 500 may include a system for capturing stone fragments that simultaneously allows access to the interior of the handle 204 and the shaft 206 via a vacuum port 504. The vacuum port 504 may include a sealable port that can be opened to allow insertion of the instrument into the handle 204 via the stone fragment capture device 502. In one example, the sealable port may include a threaded port with a cap. In other examples, the sealable port may include a self-sealing entry point, such as an iris point entry system, which includes a plurality of deflectable tabs that can abut or overlap each other in a non-deflected state to seal the entry point, but the tabs can bend or deflect away from each other to allow access into the entry point.

[0091] Vacuum port 504 and connector 510 can be aligned along axis A6 of handheld probe 202, along which shaft 206 and handle 204 extend. Thus, in the event of obstruction within handle 204 or shaft 206, such as by embedded stone fragments, the probe can be inserted into vacuum port 504 towards the distal tip 216 of shaft 206. Figure 17 Insert to push or otherwise remove stones or other obstacles.

[0092] The stone-catching device 500 can be used with Figure 3 Container 258 Figure 5 This is similar to container 308 or any other stone-catching system described or anticipated herein. However, as Figure 16 As shown, the tube connector 512 can be positioned off-axis A6 along axis A7 to allow the vacuum port 504 to be axially aligned with the connector 510. The vacuum port 504 can be coupled to the connector 510 by offsetting the outlet port 266 and outlet 316 relative to the inlet port 264 and inlet 314, respectively. Figure 3 Container 258 and Figure 5 In container 308. For example, refer to Figure 3 The outlet port 266 can be offset on the end plate 282 relative to axis A3, closer to the sidewall of the cover 262, to allow the inlet port, such as the vacuum port 504, to be positioned aligned with the inlet port 264. In this case, the valve 254 can be omitted or can be configured as a two-way valve to allow flow in both directions when activated (e.g., opened by vacuum suction to allow outflow, or opened by probe push to allow clearing of blockages). Similarly, Figure 10 The rack 402 can be modified accordingly to include a vacuum port.

[0093] The upper component 508A and the lower component 508B can be releasably connected to each other to allow access to any stone fragments trapped therein. For example, the upper component 508A and the lower component 508B can be threaded together or connected via a snap-fit ​​feature. Furthermore, a sealing member, such as an O-ring seal, can be provided between the upper component 508A and the lower component 508B.

[0094] Figure 17 yes Figure 2 A schematic cross-sectional view of the distal end 216 of the shaft 206 shows a flow restrictor 530 located in the lumen 532, configured to dimensionally limit the entry of stones into the shaft 206. The flow restrictor 530 may include a narrowing portion of the lumen 532 by means of annular or ring-shaped features. The flow restrictor 530 may define the maximum stone size that can be allowed to pass through the shaft 206, which may be smaller than the stone size that passes through the narrowest passage between the shaft 206 and the handle 204, thereby reducing the chance of blockage in the handheld probe 202. In the example, the inner diameter of the flow restrictor 530 may be larger than the largest size stone fragment expected to be collected in the stone fragment capturing device of this disclosure.

[0095] Figure 18 This is a wireframe diagram illustrating a method 600 for obtaining stone fragments via lithotripsy using the apparatus and stone fragment capture system of this disclosure. Method 600 illustrates various exemplary steps in the stone fragment recovery process. Other steps as described herein may be included, and some steps may be omitted. Furthermore, the illustrated steps may be performed in a different order.

[0096] In step 602, a surgical device, such as one of the lithotripsy devices disclosed herein, such as lithotripter 102 and handheld probe 202, can be used to break up stones in the patient's body.

[0097] In step 604, for example, by drawing out a vacuum through the medical device used in step 602, a valve of the stone fragment capture device, such as an inlet valve (e.g., valve 254, valve 304), is opened.

[0098] In step 606, the stone fragments pulled by the vacuum drawn out by the stone fragment capture device can impact the capture elements inside the stone fragment capture device, such as a tapered tube (e.g., inlet port 264), a filter (e.g., filter 256, filter 306), a valve (e.g., valve 254, valve 304), an orifice (e.g., flow restrictor valve 360), or a baffle (e.g., baffle 267).

[0099] In step 608, the stone fragments can be transferred from the main stream of fluid by the stone fragment capture device to be deposited in the container of the stone fragment capture device (e.g., container 258, container 308).

[0100] In step 610, the blockage may be cleared, for example, by extending a probe through a vacuum port (e.g., vacuum port 504) into the stone fragment capture device, through the stone fragment capture device, and into the axis of the surgical device to clear the blockage, if any.

[0101] In step 612, the biological material flowing through the stone fragment capture device impacts the filters (e.g., filters 256, filters 306) within the stone fragment capture device, thereby allowing only liquids and sufficiently small solids to pass through the filters.

[0102] In step 614, the filtration capacity of the filter can be adjusted (e.g., by rotating handle 358 or handle 366) to control the size of the debris retained in the stone fragment capture device.

[0103] In step 616, a valve of the stone fragment capture device, such as an outlet valve (e.g., flow restrictor valve 360, valve 408B), may be closed to retain the stone fragments deposited in the stone fragment capture device.

[0104] In step 618, the cylinder (e.g., cylinder 403) holding the stone fragments can be removed from the frame (e.g., frame 402) that holds the stone fragments.

[0105] In step 620, the cylinder or other container holding the stone fragments can be opened (e.g., by removing cap 262 or cap 312 or separating parts 508A and 508B) to make the stone fragments accessible, for example, for analysis.
