TECHNICAL FIELD
[0001] The utility model relates to medical surgical instrument technical field, especially a uterine cavity flusher with knot pushing function. BACKGROUND
[0002] In gynecological hysteroscopic surgery, such as Mirena ring suture fixation, it is often necessary to target the suture site for scraping and suction to remove tissue debris or blood clots and maintain a clear surgical field. However, in this process, the scraping and suction operation itself can easily agitate the wound, causing blood clots or endometrial tissue to obstruct the surgical field and affect the accuracy of the suturing operation.
[0003] Currently, the uterine cavity flusher used in clinical practice has relatively simple functions, with the main functions being flushing (injecting liquid to expand the uterine cavity and clean the wound) and suction (sucking out liquid and suspended matter). When the operation reaches the key step of suturing and knotting, the doctor needs to remove the flusher from the instrument channel and replace it with a dedicated knot pusher to enter the uterine cavity to complete the pushing and tightening of the knot. This process has the following shortcomings: first, the replacement of the instrument prolongs the operation time; second, when the instrument is replaced, the wound may bleed again, forming new blood clots and causing blurred vision, thereby affecting the efficiency of the operation.
[0004] Therefore, there is a need in clinical practice for a uterine cavity surgical instrument that integrates flushing, suction, and knot pushing functions to quickly complete the suturing operation without replacing the instrument, thereby effectively shortening the operation time and significantly improving the convenience of the operation. SUMMARY
[0005] The purpose of the present utility model is to provide a uterine cavity flusher with knot pushing function, which achieves the effect of knot pushing and flushing using only one instrument.
[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a uterine cavity flusher with knot pushing function, comprising a flusher main body and a pipe joint assembly, the front end of the flusher main body is provided with a suction pipe, the suction pipe is in communication with the flusher main body through the pipe joint assembly, one end of the suction pipe away from the pipe joint assembly is provided with a knot pushing pipe, the pipe wall of the suction pipe is provided with a suction port located at the rear side of the knot pushing pipe, the end of the knot pushing pipe is provided with a knot pushing through-hole, and the hole diameter of the knot pushing through-hole is set to decrease from the front end to the rear end.
[0007] The utility model discloses the following advantages after adopting the above technical scheme: a push knot pipe is additionally arranged at the end of the suction pipe far from the pipe joint assembly, so that the suction pipe has three functions of flushing, suction and knot pushing. The operator can complete three operations on one instrument during the operation, which significantly shortens the operation time, reduces the number of instruments entering and exiting the uterine cavity, and improves the continuity and convenience of the operation. In addition, the wall of the suction pipe is provided with a suction port located at the rear side of the push knot pipe. The suction port can suck the blood and impurities in the uterine cavity during the suction process. The suction port can also be used for line delivery, which facilitates the pulling of the suture line delivered through the push knot hole during the operation. The flexibility of the operation is improved. As the knot moves from the front end to the rear end of the push knot hole, the hole diameter gradually decreases. The reduction of the hole diameter makes the contact between the knot and the hole wall of the push knot hole gradually tight, so that the knot can be compressed and made more compact.
[0008] Further, the inner diameter of the suction pipe is larger than the inner diameter of the push knot pipe.
[0009] With the foregoing technical scheme, the larger inner diameter of the suction pipe can make more flushing liquid enter the uterine cavity through the suction pipe in unit time, which can quickly cover the uterine cavity and effectively flush the secretions and residual tissues in the uterine cavity, avoiding interference with the surgical field and enabling the doctor to perform accurate operations. During the suction operation, the larger inner diameter of the suction pipe can quickly suck out the blood clots and impurities in the uterine cavity, avoiding blockage caused by the accumulation of blood clots in the suction pipe and ensuring the stability of the suction process.
[0010] Further, the push knot pipe and the suction pipe are integrally formed.
[0011] With the foregoing technical scheme, the integral forming of the push knot pipe and the suction pipe eliminates the connection gap between the push knot pipe and the suction pipe and the problem of loose connection between the two, so that they can withstand greater external force, enhancing the structural stability of the uterine cavity flusher and avoiding the problem of loose connection between the components. Moreover, it also avoids bacterial attachment to the connection position of the two, reducing the risk of infection. Furthermore, the integral forming eliminates the connection gap between the push knot pipe and the suction pipe, so that there is no problem of liquid leakage (if liquid leakage occurs during the suction of the suspension liquid in the uterine cavity, it will cause secondary pollution in the uterine cavity) during the uterine cavity flushing process.
[0012] Further, the wall of the suction pipe located at the edge of the suction port is arc-shaped.
[0013] The edge of the suction port is rounded and smooth, the contact with the uterine cavity wall is more gentle during movement, the possibility of scratching the tissue is greatly reduced, the risk of complications such as postoperative bleeding and infection is reduced, and the rounded transition of the edge of the suction port can make the movement of the suction tube in the uterine cavity more smooth, and reduce the resistance during operation.
[0014] Further, the end edge of the push knot tube is rounded and transitioned.
[0015] The edge of the push knot tube is rounded and smooth, the contact with the uterine cavity wall is more gentle during movement, the possibility of scratching the tissue is greatly reduced, the risk of complications such as postoperative bleeding and infection is reduced, and the rounded transition of the edge of the suction port can make the movement of the suction tube in the uterine cavity more smooth, and reduce the resistance during operation.
[0016] Further, the first water pipe joint and the second water pipe joint are further included, the flusher body includes a shell, the shell is provided with a communication port in communication with the pipe joint assembly, a water inlet in communication with the first water pipe joint, and a water outlet in communication with the second water pipe joint, a three-way valve is installed in the shell, and the three-way valve is configured to have a first working state, a second working state and a third working state. In the first working state, the three-way valve communicates the communication port and the water inlet; in the second working state, the three-way valve communicates the communication port and the water outlet; and in the third working state, the three-way valve blocks the communication port, the water inlet and the water outlet from each other.
[0017] The foregoing technical solutions are adopted, in the first working state, the external water source enters the shell through the first water pipe joint, flows to the pipe joint assembly through the communication port, and then realizes the water injection flushing operation in the uterine cavity, thereby ensuring the clear inspection view; when in the second working state, the three-way valve communicates the communication port and the water outlet, and the secretions, blood clots and the like flushed in the uterine cavity are sucked out through the pipe joint assembly, the communication port and the second water pipe joint. The water outlet can ensure the cleanliness of the environment in the uterine cavity; and in the third working state, the communication port, the water inlet and the water outlet are blocked from each other, so that the water flow channel can be cut off when the flushing operation is not needed, thereby avoiding the accidental flow of the water source to interfere with the operation.
[0018] Further, the flusher body further includes a handle for switching the working state of the three-way valve, and the handle partially extends outside the shell.
[0019] The foregoing technical solutions are adopted, and the handle improves the convenience of use for the operator.
[0020] Further, the first water pipe joint and the second water pipe joint are welded to the shell.
[0021] Adopting the preceding technical scheme, the welding greatly reduces the possibility of liquid leakage, thereby ensuring the sealing of the first water pipe joint, the second water pipe joint and the shell, and reducing the occurrence of water leakage. In addition, the welding mode can make the connection of the first water pipe joint, the second water pipe joint and the shell more stable, and can withstand external forces such as water flow impact, equipment movement, etc., and is not easy to loosen or fall off, thereby ensuring the reliability of use.
[0022] Further, the first sealing ring is installed between the pipe joint assembly and the flusher body, and the second sealing ring is installed between the suction pipe and the pipe joint assembly.
[0023] Adopting the preceding technical scheme, the first sealing ring and the second sealing ring are both elastic, can form a close fit on the contact surface, and fill the manufacturing tolerance, thereby preventing liquid leakage and ensuring the reliability of use and the sealing between the pipe joint assembly, the flusher body and the suction pipe.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

It should be understood that in the utility model, "including" and "having" and any variation thereof are intended to cover non-exclusive inclusion. It should be understood that in the utility model, "multiple" refers to two or more than two. And / or is only a description of the association relationship between the associated objects, which means that there are three kinds of relationships, for example, X and / or Y can represent: three cases of X alone, X and Y exist at the same time, and Y alone. The character " / " generally represents that the front and rear associated objects are in an "or" relationship. "Including X, Y and Z", "including X, Y, Z" means that X, Y and Z are all included, "including X, Y or Z" means that one of X, Y and Z is included, and "including X, Y and / or Z" means that any one or any two or three of X, Y and Z is included.
[0032] The technical scheme of the utility model will be described in detail below with specific examples. The following specific examples can be combined or replaced according to actual conditions, and the same or similar concepts or processes may not be described in some examples.
[0033] As shown in Figure 1 and Figure 2 The utility model provides a kind of uterine cavity flusher with push knot function, including flusher main body 100 and pipe joint assembly 200, flusher main body 100 front end is equipped with suction tube 300, suction tube 300 is communicated with flusher main body 100 by pipe joint assembly 200, suction tube 300 is equipped with push knot pipe 310 in the end away from pipe joint assembly 200, the pipe wall of suction tube 300 is equipped with suction port 320 located in the rear side of push knot pipe 310, the end of push knot pipe 310 is equipped with push knot through hole 311.
[0034] It can be understood that push knot pipe 310 is additionally provided at the end of suction tube 300 away from pipe joint assembly 200, so that it has three functions of flushing, suction and push knot. The operator does not need to switch between different instruments during operation, and can complete three operations on one instrument, significantly shortening the operation time, reducing the number of instruments entering and exiting the uterine cavity, and improving the continuity and convenience of operation. In addition, the pipe wall of suction tube 300 is equipped with suction port 320 located in the rear side of push knot pipe 310, which can suck out the blood and impurities in the uterine cavity during suction; When flushing, the flushing liquid can be injected into the uterine cavity, and at the same time, suction port 320 can also be used for line delivery, which facilitates the pulling of the suture line transmitted from push knot through hole 311 during operation. Improve the flexibility of operation.
[0035] Specifically, as shown in Figure 4 To make the knot tighter, the hole diameter of the knot pushing through hole 311 is set to decrease from the front end to the rear end, so that the knot pushing through hole 311 forms a shape similar to a tapered hole. In this way, as the knot moves in the knot pushing through hole 311 from the front end to the rear end, the hole diameter gradually decreases, and the decrease in the hole diameter makes the contact between the knot and the hole wall of the knot pushing through hole 311 gradually tight, so that the knot can be compressed.
[0036] Further, the inner diameter R1 of the suction tube 300 is greater than the inner diameter R2 of the knot pushing tube 310, and the larger inner diameter of the suction tube 300 can make more flushing liquid pass through the suction tube 300 into the uterine cavity per unit time, which can quickly cover the uterine cavity and effectively flush the secretions and residual tissues in the uterine cavity, avoid interfering with the surgical field, and enable the doctor to perform accurate operations; during the suction operation, the larger inner diameter of the suction tube 300 can quickly suck out the blood clots and impurities in the uterine cavity, avoid the accumulation of blood clots in the suction tube 300 causing blockage, and ensure the stability of the suction process.
[0037] As a preferred, the inner diameter R2 of the knot pushing tube 310 is set to be the same as the rear end diameter R3 of the knot pushing through hole 311. Since there may be a certain visual blind area inside the knot pushing tube 310 during the operation, setting the inner diameter of the knot pushing tube 310 to be the same as the rear end diameter of the knot pushing through hole 311 can make the operation more smooth during the knot pushing process, and eliminates the process of trying to find the knot pushing through hole 311 in the knot pushing tube 310.
[0038] More preferably, the knot pushing tube 310 and the suction tube 300 are integrally formed. The integral forming of the knot pushing tube 310 and the suction tube 300 eliminates the connection gap between the knot pushing tube 310 and the suction tube 300 and the problem of loose connection between the two, so that it can withstand greater external force and enhance the structural stability of the uterine cavity flusher, avoiding the problem of loose connection between the parts. Moreover, it also avoids the attachment of bacteria to the connection position of the two, reducing the risk of infection. Furthermore, the integral forming eliminates the connection gap between the knot pushing tube 310 and the suction tube 300, so that there is no problem of liquid leakage (if there is liquid leakage when the suspension liquid in the uterine cavity is sucked, it will cause secondary pollution in the uterine cavity) during the uterine cavity flushing process.
[0039] In addition, in order to reduce the risk of tissue scratching, the edge of the suction tube 300 and the end edge arc transition of the knot pushing tube 310 are rounded, which not only makes the contact with the uterine cavity wall during movement more gentle and reduces the risk of postoperative bleeding, infection and other complications, but also makes the movement of the suction tube 300 in the uterine cavity more smooth and reduces the resistance during operation.
[0040] To be specific, as shown in Figure 1 ,Figure 3 and Figure 5 As shown in the figure, the uterine cavity flusher further comprises a first water pipe joint 110 and a second water pipe joint 120, the flusher body 100 comprises a shell 130 and a handle 140 partially extending outside the shell 130, the shell 130 is provided with a communication port 131 communicating with the pipe joint assembly 200, a water inlet port 132 communicating with the first water pipe joint 110, and a water outlet port 133 communicating with the second water pipe joint 120, and a three-way valve 150 is installed in the shell 130, the three-way valve 150 is configured to have a first working state, a second working state and a third working state, and the handle 140 is used to switch the working state of the three-way valve 150, and the handle 140 improves the convenience of the operator.
[0041] In another embodiment, the working state of the three-way valve 150 can be switched by using a motor-driven mode, specifically, a small motor is installed in the shell 130 and connected with the three-way valve 150 through a gear transmission device. When it is needed to change the working state of the three-way valve 150, the motor is driven by sending a corresponding instruction to the motor through the control circuit. In order to facilitate the operator to send the instruction, a button can be arranged outside the shell 130. The operator presses different buttons, and the control circuit receives the signal and drives the motor to operate, which in turn drives the gear transmission device to work, and then the three-way valve 150 is switched to different working states.
[0042] In the first working state, the three-way valve 150 communicates the communication port 131 and the water inlet port 132; in the second working state, the three-way valve 150 communicates the communication port 131 and the water outlet port 133; and in the third working state, the three-way valve 150 isolates the communication port 131, the water inlet port 132 and the water outlet port 133 from each other.
[0043] Specifically, in the first working state, the external water source enters the shell 130 through the first water pipe joint 110, flows to the pipe joint assembly 200 through the communication port 131, and then realizes the water flushing operation into the uterine cavity to ensure the clear inspection view; when in the second working state, the three-way valve 150 communicates the communication port 131 and the water outlet port 133, and the secretions, blood clots and the like flushed in the uterine cavity are sucked out through the pipe joint assembly 200, the communication port 131 and the second water pipe joint 120. The environment in the uterine cavity can be ensured to be clean; and in the third working state, the communication port 131, the water inlet port 132 and the water outlet port 133 are isolated from each other, and when the flushing operation is not needed, the water flow channel can be cut off to avoid the accidental flow of the water source to interfere with the operation.
[0044] In this embodiment, as Figure 1As shown, as preferred, the pipe joint assembly 200 is communicated with the inside of the shell 130 through the communication port 131, the first water pipe joint 110 is communicated with the inside of the shell 130 through the water inlet port 132, the communication port 131 is arranged opposite to the water inlet port 132, when the three-way valve 150 is in the first working state, the communication port 131 and the water inlet port 132 are communicated by the three-way valve 150, so that the water in the first water pipe joint 110 is injected into the pipe joint assembly 200, and then into the suction pipe 300, so as to flush the uterine cavity; the second water pipe joint 120 is communicated with the inside of the shell 130 through the water outlet port 133, the axis a of the water outlet port 133 is arranged perpendicular to the axis of the communication port 131, when the three-way valve 150 is in the second working state, the communication port 131 and the water outlet port 133 are communicated by the three-way valve 150, so that the blood clots and impurities in the uterine cavity are sucked into the pipe joint 220 through the suction pipe 300, and then are discharged from the water outlet port 133 by the three-way valve 150, so as to achieve the purpose of cleaning the uterine cavity.
[0045] It is worth mentioning that, as shown in the above, Figure 1 as preferred, when the three-way valve 150 is in the third working state, the axis b of the horizontal pipe 151 of the three-way valve 150 is arranged at an angle of 45° with the axis a of the water outlet port 133 in the shell 130, when the operator drives the handle 140 to move forward, the three-way valve 150 is in the second working state; when the operator drives the handle 140 to move backward, the three-way valve 150 is in the first working state.
[0046] It should be noted that, in another embodiment, the arrangement angle between the communication port 131, the water inlet port 132 and the water outlet port 133 and the three-way valve 150 is not limited to the angle arranged in the above embodiment, and can be adjusted according to actual needs, so as to optimize the flow direction and speed of the fluid in the flusher, so as to better meet the special needs of various surgical operations, and ensure the efficiency and accuracy of the flushing process.
[0047] It should be explained that the inner wall profile of the shell 130 is circular, for example, in the first working state of the three-way valve 150, when the driving handle 140 is moved to switch the three-way valve 150 to the first working state, the horizontal pipe 151 of the three-way valve 150 communicates the communication port 131 and the water inlet port 132, at this time, the other pipe port of the three-way valve 150 is tightly fitted with the circular inner wall of the shell 130, effectively plugging the pipe port, avoiding liquid leakage, and ensuring sealing.
[0048] In addition, in order to ensure the sealed connection between them, in the embodiment, the first water pipe joint 110, the second water pipe joint 120 and the shell 130 are welded. The welding greatly reduces the possibility of liquid leakage, thereby ensuring the sealing of the first water pipe joint 110, the second water pipe joint 120 and the shell 130, and reducing the occurrence of water leakage. In addition, the welding can make the connection of the first water pipe joint 110, the second water pipe joint 120 and the shell 130 more stable, can withstand external forces such as water flow impact, equipment movement, etc., is not easy to loosen or fall off, and ensures the reliability of use.
[0049] Further, as shown in Figure 1 The first sealing ring 160 and the second sealing ring 170 are both elastic, can form a close fit on the contact surface, fill the manufacturing tolerance, thereby preventing liquid leakage, ensuring the reliability during use, and ensuring the sealing between the pipe joint assembly 200, the flusher body 100 and the suction pipe 300.
[0050] In detail, the pipe joint assembly 200 is composed of a pipe joint nut 210 and a pipe joint 220, the pipe joint nut 210 and the pipe joint 220 are connected through a third sealing ring 230, the suction pipe 300 is inserted into the pipe joint 220, and the pipe joint nut 210 is inserted into the flusher body 100.
