Description

Technical Field

[0002] Modern medicine increasingly advocates and attaches importance to the concepts of "minimally non-invasive" and "humanistic care". Endoscopic surgery can achieve the same surgical effect as traditional surgical methods. Due to its advantages such as small incision, reduced postoperative pain, fast recovery, and shortened hospital stay, it has become the mainstream surgical procedure in the field of surgery. Taking gynecological surgery as an example, it accounts for more than 60% of all surgeries. Endoscopic surgery is a highly instrument-dependent procedure, in which the application of energy instruments such as monopolar and bipolar energy instruments is indispensable in surgical cutting, hemostasis and other operations. How to better protect the health of medical staff during surgery is also receiving more and more attention.

[0003] At present, most energy devices use heat energy or high-speed low-frequency vibration mechanical energy to denature proteins, and a large amount of smoke will be generated in the process. If the smoke cannot be effectively and promptly eliminated, the operation area will be blurred, obstructing the surgical field of view and affecting the safety of surgical operations; the operation needs to be suspended after the smoke dissipates and the surgical field of view is clear, affecting the continuity of the operation and increasing the time cost of the operation; these fumes will also have potential harm to the health of patients undergoing surgery, doctors and nurses participating in the operation. In addition, when doctors use endoscopes to achieve remote visualization operations in the patient's body cavity, the endoscope lens is usually contaminated by peritoneum or other body fluids, blood, aerosol fat, tissue particles, smoke, debris or condensation, which will affect the doctor's field of view observed through the external monitor / screen.

[0066] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0067] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "setting" or "connection" should be understood in a broad sense. For example, the term "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0068] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the said features.

[0069] In the present invention, unless otherwise stated, the directional words used, such as "inside" and "outside", are defined as the inside and outside of the corresponding parts. In addition, the terms "proximal" and "distal" refer to the distance between the clinician and the various structures on the surgical instrument when the clinician manipulates the surgical instrument. "Proximal" and "proximal end" refer to the part close to the clinician, and "distal" and "distal end" refer to the part away from the clinician; for example, the sleeve joint 2 is located on the proximal side of the puncture sleeve 1, and "axial" is defined by the arrangement direction of the puncture device provided by the present invention. Specifically, in the drawings provided by the present invention, "axial" is the length extension direction of the puncture sleeve 1. The directional words used are based on the orientation or positional relationship shown in the drawings, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention; the directional terms of the present invention should be understood in conjunction with the actual installation state.

[0070] The multifunctional puncture device provided by the present invention is shown in FIG. Figures 1 to 13 , comprising a puncture cannula 1 with openings at both ends, a cannula joint 2 connected to the puncture cannula 1 and a puncture needle 3, a drainage channel 17, an infusion channel 15 and a gas supply channel 16 are formed in the puncture cannula 1, a puncture needle channel 21 connected to the drainage channel 17 is provided on the cannula joint 2, and the puncture needle 3 is detachably plugged into the puncture needle channel 21 and the drainage channel 17, an end of the puncture cannula 1 away from the cannula joint 2 is provided with a smoke exhaust structure connected to the drainage channel 17, a liquid spray hole 13 connected to the infusion channel 15 and an air jet hole 14 connected to the gas supply channel 16, and a smoke exhaust control component 22 connected to the puncture needle channel 21, a liquid spray control component 23 connected to the infusion channel 15 and an air jet control component 24 connected to the gas supply channel 16 are provided on the cannula joint 2.

[0071] According to the present invention, the puncture needle 3 and the sleeve joint 2 are configured to be detachably connected, and the drainage channel 17 and the puncture needle channel 21 are configured to be suitable for the insertion of the energy device 5 commonly used in minimally invasive surgery, so that after the puncture device completes the puncture, the puncture needle 3 can be pulled out and the energy device 5 can be inserted, and the energy device 5 can be extended from the distal end of the puncture sleeve 1 for surgical operation; the end of the puncture needle 3 away from the sleeve joint 2 can extend out of the port of the puncture sleeve 1 to perform the puncture operation. However, the present invention does not exclude the puncture needle 3 and the sleeve joint 2 being configured to be fixedly connected, a channel for inserting the energy device 5 is provided inside the puncture needle 3, or a channel for inserting the energy device 5 is provided on the sleeve joint 2 in parallel with the puncture needle channel 21.

[0072] The multifunctional puncture device provided by the above basic embodiment of the present invention can remove the puncture needle 3 and replace it with the energy device 5 after the puncture device completes the puncture, so as to perform minimally invasive surgery; when smoke is generated during the operation of the energy device 5, the smoke exhaust structure of the puncture cannula 1 is close to the distal end port of the puncture cannula 1, and the smoke is timely absorbed and transmitted to the smoke exhaust control part on the cannula joint 2 through the exhaust channel 17 and the puncture needle channel 21, and then discharged through the smoke exhaust control part, so as to maintain the clarity of the operation area of ​​the energy device 5 and ensure the safety of the surgical operation; and the energy device 5 When the endoscope lens used in conjunction is contaminated, cleaning liquid is input through the liquid spray control part on the sleeve joint 2, transmitted to the liquid spray hole 13 of the puncture sleeve 1 through the liquid infusion channel 15, and then the lens is sprayed with liquid through the liquid spray hole 13 for cleaning in time, and gas is input through the jet control part on the sleeve joint 2, transmitted to the jet hole 14 of the puncture sleeve 1 through the gas transmission channel 16, and then the lens is sprayed and purged through the jet hole 14, so that the endoscope lens can be cleaned while the operation is in progress, thereby ensuring the field of view of the operation, allowing the operation to be carried out continuously, and saving operation time.

[0073] As a preferred embodiment of the smoke exhaust structure in the present invention, see Figures 3 to 7 The smoke exhaust structure includes a first smoke exhaust port 11, which is located at the end of the puncture sleeve 1 away from the sleeve joint 2 and is connected to the exhaust channel 17. The first smoke exhaust port 11 is set at the distal end of the puncture sleeve 1, close to the smoke source, so that the smoke generated by the energy device 5 can be absorbed and discharged at the moment of generation. The first smoke exhaust port 11 can be Figure 3 The notch shown in the figure is formed by the distal end port of the puncture sleeve 1 being recessed toward the proximal side, or it can be other structures, such as Figure 7 The circular or rectangular holes shown. Figure 5 and Figure 6 , the end of the puncture sleeve 1 away from the sleeve joint 2 is set as an outer cone structure, the inner contour of the outer cone structure is a conical surface 18 with a cross-sectional circumference gradually increasing from the distal side to the proximal side, and its distal port is provided with a chamfer 19. At this time, the outer contour of the outer cone structure gradually increases from the distal side to the proximal side, which can reduce the obstruction of the head of the puncture needle 3 or the energy device 5, facilitate endoscopic observation, and make the insertion of the puncture device smoother. The inner contour of the outer cone structure forms a conical surface 18 with a cross-sectional circumference gradually increasing from the distal side to the proximal side, thereby facilitating the smooth insertion of the puncture needle 3 or the energy device 5; the distal port of the outer cone structure is provided with a chamfer 19, which can facilitate the smooth withdrawal of the puncture needle 3 or the energy device 5.

[0074] Preferably, the smoke exhaust structure further includes a second smoke exhaust port 12, which is located on the side wall of the end of the puncture sleeve 1 away from the sleeve joint 2 and is connected to the exhaust channel 17. The first smoke exhaust port 11 and the second smoke exhaust port 12 cooperate to increase the smoke exhaust area and improve the smoke exhaust rate. The second smoke exhaust port 12 can be set as a hole structure, such as a circular hole, a rectangular hole, etc., preferably a plurality of smoke exhaust holes arranged in sequence along the length direction of the puncture sleeve 1.

[0075] As a preferred embodiment of the puncture needle 3, see Fig.13 The distal end of the puncture needle 3 is provided with a special-shaped structure 31 capable of filling the first smoke exhaust port 11. The puncture needle 3 is inserted into the puncture needle channel 21 and the exhaust channel 17, and the special-shaped structure 31 at the distal end of the puncture needle 3 can be inserted into the first smoke exhaust port 11, so that the distal end of the puncture device forms a smooth structure, which helps to reduce the resistance during puncture.

[0076] In order to better cooperate with the smoke exhaust structure, in the present invention, see Figure 2 The smoke exhaust control part 22 includes a smoke exhaust connector 221 connected to the side wall of the sleeve connector 2 and a smoke exhaust switch 222. The smoke exhaust connector 221 is provided with a smoke exhaust external interface 223. The smoke exhaust switch 222 can control the connection or disconnection between the smoke exhaust connector 221 and the puncture needle channel 21. The smoke exhaust control part 22 generally needs to be connected to the smoke exhaust device through a hose using the smoke exhaust external interface 223 to generate corresponding suction or negative pressure, absorb smoke from the first smoke exhaust port 11 and the second smoke exhaust port 12, and input it into the smoke exhaust device for processing; when the smoke exhaust function is not needed, the smoke exhaust switch 222 can be used to disconnect the smoke exhaust connector 221 from the puncture needle channel 21. When the smoke exhaust function is needed, the smoke exhaust switch 222 can be used to connect the smoke exhaust connector 221 to the puncture needle channel 21. For example, the smoke exhaust switch 222 can be a knob switch located on the smoke exhaust connector 221 for easy operation.

[0077] According to the present invention, see Fig.10 The inner diameter d of the smoke exhaust connector 221 is greater than 4.5 mm. Setting the inner diameter d of the smoke exhaust connector 221 to be larger than the conventional connector inner diameter of the puncture device in the prior art can improve the efficiency of exhausting smoke from the exhaust channel 17 and the smoke exhaust connector 221.

[0078] According to the present invention, the aperture of the liquid spray hole 13 is smaller than the aperture of the second smoke exhaust port 12, and the cleaning liquid input by the liquid spray control unit 23 is generally physiological saline, and the temperature is generally 37-39° C. The aperture of the air jet hole 14 is also smaller than the aperture of the second smoke exhaust port 12, and the apertures of the air jet hole 14 and the liquid spray hole 13 can be the same or different; the gas input by the air jet control unit 24 is generally carbon dioxide.

[0079] In order to better flush the endoscope lens, the liquid spray hole 13 can be designed as an inclined through hole, that is, there is an acute angle between the axis of the liquid spray hole 13 and the axis of the puncture sleeve 1. For example, the liquid spray hole 13 is designed to be inclined toward the proximal side, so that the liquid spray hole 13 sprays physiological saline from the distal side to the proximal side. Alternatively, the liquid spray hole 13 can also be designed to be inclined in other directions. Similarly, the air jet hole 14 can also be designed as an inclined through hole to facilitate the inclined injection of carbon dioxide gas from the distal side to the proximal side. Since the liquid spray hole 13 and / or the air jet hole 14 are designed to be inclined toward the proximal side, the endoscope lens can be better cleaned in actual operation. The through hole can be single or multiple. When there are multiple through holes, they can be arranged in any manner, such as a plum blossom arrangement. See. Fig.17 The spray angles of the through holes can be the same or different. Preferably, the spray angles of the through holes are different, so that the coverage of the cleaning area is larger. The double-dotted line indicates the direction of the through hole tilt angle. Of course, the liquid spray hole 13 and the air jet hole 14 can also be designed without tilting.

[0080] More preferably, see Fig.18 The side wall of the puncture sleeve 1 is provided with a flow guiding structure 10 located between the liquid spray hole 13 and the air jet hole 14. The flow guiding structure 10 may be a flow guiding groove and / or a flow guiding ridge. The flow guiding ridge is a protruding structure for guiding. After the liquid is sprayed from the liquid spray hole 13, residual liquid may appear on the air jet hole 14, so that when the air jet hole 14 sprays, the residual liquid is sprayed to the lens surface by the gas; when the flow guiding structure 10 is a flow guiding groove, the residual liquid can be guided to flow away from the air jet hole 14. When the flow guiding structure 10 is a flow guiding ridge, the liquid can be further blocked from flowing to the air jet hole 14.

[0081] In order to better cooperate with the spray hole 13, in the present invention, see Figure 2 The liquid spray control part 23 includes a liquid spray connector 231 connected to the side wall of the sleeve connector 2 and a liquid spray switch 232. The liquid spray connector 231 is provided with a liquid spray external interface 233. The liquid spray switch 232 can control the liquid spray connector 231 to be connected or disconnected with the liquid infusion channel 15. The liquid spray control part 23 generally needs to be connected to the cleaning liquid supply device through a hose using the liquid spray external interface 233 so that the cleaning liquid can be input and sprayed from the liquid spray hole 13; when the liquid spray function is not needed, the liquid spray switch 232 can be used to disconnect the liquid spray connector 231 from the liquid infusion channel 15. When the liquid spray function is needed, the liquid spray switch 232 can be used to connect the liquid spray connector 231 with the liquid infusion channel 15. By way of example, the liquid spray switch 232 can be a knob switch located on the liquid spray connector 231 for easy operation.

[0082] In order to better cooperate with the jet hole 14, in the present invention, see Figure 2The jet control part 24 includes a jet connector 241 connected to the side wall of the sleeve connector 2 and a jet switch 242. The jet connector 241 is provided with a jet external interface 243. The jet switch 242 can control the jet connector 241 to be connected or disconnected with the gas transmission channel 16. The jet control part 24 generally needs to be connected to the gas supply device through a hose using the jet external interface 243 so that gas can be input and ejected from the jet hole 14; when the jet function is not needed, the jet switch 242 can be used to disconnect the liquid injection connector 231 from the gas transmission channel 16. When the jet function is needed, the jet switch 242 is used to connect the jet connector 241 to the gas transmission channel 16. By way of example, the jet switch 242 can be a knob switch located on the jet connector 241 for easy operation.

[0083] In the present invention, the gas supply channel 16, the infusion channel 15 and the drainage channel 17 are independent channels. The infusion channel 15 and the gas supply channel 16 can be set as straight channels along the axial direction of the puncture cannula 1, or can be set as curved channels, for example, arranged in the form of a spiral line on the inner wall of the puncture cannula 1.

[0084] As a preferred embodiment of the puncture cannula 1 of the present invention, a partition is provided in the puncture cannula 1, and the partition is connected to the inner wall of the puncture cannula 1 to form a drainage channel 17, an infusion channel 15 and a gas delivery channel 16. The partition can be Figure 8 The structure shown in the figure makes the infusion channel 15 adjacent to the gas delivery channel 16. The structure can also be deformed to a certain extent. For example, the horizontal straight plate above the separator can be a curved plate, and the vertical plate below the separator can be a curved plate; or the separator can also divide the space inside the puncture cannula 1 into Fig. 9 The structure shown enables the infusion channel 15 and the gas channel 16 to be arranged separately; alternatively, other structures can also be arranged in the puncture cannula 1 to separate the space in the puncture cannula 1 into the drainage channel 17, the infusion channel 15 and the gas channel 16. In order to avoid mutual interference between the infusion channel 15, the gas channel 16 and the drainage channel 17, the distal ends of the infusion channel 15 and the gas channel 16 are closed. In addition, the infusion channel 15 and the gas channel 16 can also be designed in other ways, for example, the thickness of the tube wall of the puncture cannula 1 is relatively large, so that the infusion channel 15 and the gas channel 16 are arranged in the tube wall of the puncture cannula 1.

[0085] In the present invention, a liquid spray mark for indicating the position of the liquid spray hole 13 and an air jet mark for indicating the position of the air jet hole 14 are provided on the puncture cannula 1, which facilitates medical personnel to quickly find the positions of the liquid spray hole 13 and the air jet hole 14 during minimally invasive surgery and clean the lens of the endoscope. A scale mark can also be provided on the outer surface of the puncture cannula 1 near the cannula joint 2 to facilitate prompting the surgeon of the insertion depth of the puncture cannula 1.

[0086] As a preferred embodiment of the sleeve joint 2 in the present invention, a sealing assembly 4 connected to the sleeve joint 2 is provided at one end of the sleeve joint 2 away from the puncture sleeve 1, and the puncture needle 3 can pass through the sealing assembly 4 and enter the puncture needle channel 21 to improve the sealing performance inside the puncture device.

[0087] Among them, see Figure 2 The sealing assembly 4 includes two sealing pads and a sealing end cover 44 connected in sequence, and the two sealing pads and the sealing end cover 44 are respectively provided with a hollow structure suitable for the puncture needle 3 to pass through.

[0088] According to the present invention, the sealing assembly 4 further includes a gasket 42 located between the two sealing pads, and the two sealing pads and the gasket 42 can be independently provided or formed into an integral structure. Preferably, the two sealing pads and the gasket 42 are an integrally formed part.

[0089] In the present invention, one of the two sealing pads is set as a first sealing pad 41, and the other is set as a second sealing pad 43.
