Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical instruments, in particular to an operating instrument. Background Art
[0002] During endoscopic surgery, some operating instruments are often used to complete a certain operation, such as using a stone removal basket to remove stones from the body, using biopsy forceps to remove tissue samples from the lesion, and using a sealing basket to block the cavity.
[0003] It can be seen that the above operations require these instruments to directly enter the natural cavity of the human body. Repeatedly used instruments often cause cross infection due to incomplete disinfection, so this type of surgery often uses disposable operating instruments, but in some cases these disposable operating instruments have the problem of being repeatedly used and cannot effectively avoid cross infection. Summary of the invention
[0004] The purpose of the present invention is to design an operating instrument to solve the problem of cross infection caused by the instrument.
[0005] The present invention is achieved through the following technical solutions:
[0006] The present application provides an operating instrument, comprising a fixed part, a movable part, an instrument part, a container and a puncture part; the fixed part is provided with a guide channel extending from the proximal end to the distal end; the movable part can reciprocate between a first position and a second position along the guide channel relative to the fixed part; the proximal end of the instrument part is fixedly connected to the movable part; glue liquid is stored in the container, and the container is arranged on the moving path of the movable part; the puncture part is connected to the movable part and protrudes from the distal end surface of the movable part toward the container; wherein, when the movable part moves to the first position, the puncture part can puncture the container; the glue liquid can flow out from the punctured part on the container into the guide channel.
[0007] When the above-mentioned setting structure is adopted, a container that can be pierced by a piercing member is arranged on the moving path of the moving member that drives the instrument member to move. The piercing member is arranged at the distal end of the moving member so that the piercing member has the ability to pierce the container during operation. In this way, when the moving member moves to the first position, the moving member pierces the container through the piercing member, so that the glue in the container can flow into the guide channel through the piercing part. After a period of time, the glue in the guide channel solidifies to form an obstacle that hinders the movement of the moving member or a glue structure that connects the inner side wall of the guide channel with the moving member, so that the operating instrument cannot be used normally. This measure limits the normal use time of the operating instrument, avoids repeated use of the operating instrument, and can better avoid the problem of cross infection caused by repeated use.
[0008] To further implement the present invention in a better manner, the following configuration is particularly adopted: the guide channel is configured as a hole, and the moving member is plug-fitted and slidably matched with the guide channel.
[0009] In order to further better realize the present invention, the following configuration is particularly adopted: a first guide groove is provided on the peripheral wall of the moving member, and a distal end of the first guide groove is provided as an opening formed on the distal end surface of the moving member.
[0010] When the above-mentioned setting structure is adopted, the distal end of the first guide groove arranged on the peripheral wall of the moving part forms an opening on the distal end surface of the moving part, so that part of the glue flowing into the guide channel can be transferred to the position between the outer periphery of the moving part and the inner side wall of the guide channel through the first guide groove, so that the glue can form a bonding structure between the outer periphery of the moving part and the inner side wall of the guide channel after solidification, so as to more reliably fix the moving part and the fixed part.
[0011] In order to better realize the present invention, the following setting structure is particularly adopted: a second guide groove is provided on the peripheral wall of the movable member, both ends of the second guide groove are located between the proximal end and the distal end of the movable member, and at least one end of the second guide groove is laterally connected to the first guide groove.
[0012] When the above-mentioned setting structure is adopted, both ends of the second guide groove arranged on the peripheral wall of the moving part are located between the proximal end and the distal end of the moving part, and are laterally connected to the first guide groove through at least one end, so that the second guide groove can be used as a branch to transfer the glue entering the first guide groove more evenly to the position between the outer periphery of the moving part and the inner wall of the guide channel, and a bonding structure can be formed on a wider surface, making the bonding fixation of the moving part and the fixed part more reliable.
[0013] In order to further better realize the present invention, the following setting structure is particularly adopted: the movable part includes a push rod and an operating handle connected to the proximal end of the push rod, and the push rod is slidably matched with the guide channel; the peripheral wall of the fixed part is provided with a window extending along the extension direction of the guide channel, and the operating handle extends from the window to the outside of the fixed part.
[0014] To further implement the present invention, the following structure is particularly adopted: a fixed finger ring for placing the thumb is provided at the proximal end of the fixing member, and movable finger rings for placing the index finger and the middle finger are provided on opposite sides of the portion of the operating handle located outside the fixing member.
[0015] In order to further better realize the present invention, the following setting structure is particularly adopted: it also includes a protective tube whose distal end is fixed to the fixing part, the instrument part is inserted into the protective tube, the distal end of the protective tube is fixed and sealed to the fixing part, and the proximal end is closer to the proximal end of the fixing part than the proximal end of the container.
[0016] When the above-mentioned structure is adopted, the distal end of the protective tube is sealed with the fixing member, and the proximal end extends beyond the container, which can better prevent the glue entering the guide channel from adhering to the instrument part.
[0017] In order to further implement the present invention in a better manner, the following configuration is particularly adopted: the distal end surface of the moving member is provided with an exhaust passage extending toward the proximal end.
[0018] When the above-mentioned structure is adopted, the exhaust channel is arranged on the distal surface of the moving part, which can smoothly exhaust air when the moving part moves toward the distal end or smoothly replenish air when the moving part moves backward toward the proximal end, ensuring that the moving part can move smoothly.
[0019] In order to further implement the present invention in a better manner, the following configuration is particularly adopted: the puncture member is configured as a needle tube with an obliquely cut head.
[0020] When the above-mentioned structure is adopted, the piercing member is a hollow needle tube, and the oblique cutting of its head will form an oblique cut extending along the axial direction. When the piercing member pierces the container, the glue can be discharged more smoothly through the oblique cut in a process.
[0021] To further better implement the present invention, the following configuration is particularly adopted: when the moving member moves to the first position, the moving member compresses the container along the extending direction of the guide channel.
[0022] In order to further better realize the present invention, the following setting structure is particularly adopted: it also includes a catheter, the catheter is fixed to the fixing part, and the instrument part is inserted into the catheter, wherein when the movable part is located in the second position, the distal end of the instrument part is located in the catheter, and when the movable part is located in the first position, the distal end of the instrument part is located outside the catheter.
[0023] In order to better implement the present invention, the following configuration is particularly adopted: the container is configured as an annular capsule arranged around the instrument.
[0024] In order to further implement the present invention, the following configuration structure is particularly adopted: the moving member is connected to a plurality of puncture members, and all the puncture members are sequentially arranged around the instrument member.
[0025] In order to further better realize the present invention, the following setting structure is particularly adopted: it also includes a mounting frame, the mounting frame includes a cylindrical portion and a flange portion arranged at the distal end of the cylindrical portion, the cylindrical portion is passed through the center hole of the container and supports the inner circumferential wall of the container, and the flange portion supports the distal end surface of the container.
[0026] When the above-mentioned setting structure is adopted, the mounting frame supports the inner peripheral wall of the container through the cylindrical body, which can maintain the peripheral shape of the container and effectively prevent the inward contraction of the container from affecting the movement of the instrument.
[0027] The present invention has the following advantages and beneficial effects:
[0028] In the present invention, a container that can be punctured by a puncture member is arranged on the moving path of the moving member that drives the instrument member to move, and the puncture member is arranged at the distal end of the moving member so that the puncture member has the ability to puncture the container during operation. In this way, when the moving member moves to the first position, the moving member punctures the container through the puncture member, so that the glue in the container can flow into the guide channel through the puncture site. After a period of time, the glue in the guide channel solidifies to form an obstacle that hinders the movement of the moving member or a glue structure that connects the inner side wall of the guide channel with the moving member, so that the operating instrument cannot be used normally. This measure limits the normal use time of the operating instrument, avoids repeated use of the operating instrument, and can better avoid the problem of cross infection caused by repeated use.

[0059] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.
[0060] The operating device of the present application has measures to limit the normal use time to avoid the possibility of repeated use, which can better avoid the problem of cross infection caused by repeated use, such as Figure 1 - Fig.10 As shown, it is particularly configured as follows:
[0061] The operating instrument basically comprises a fixing part 10 , a moving part 20 , an instrument part 30 , a container 40 and a puncture part 50 .
[0062] The fixing member 10 serves as a supporting member of the entire operating device and provides a mounting base for other members, and other members, such as the moving member 20, the device member 30, and the container 40, are mounted directly or indirectly on the fixing member 10. When in use, the fixing member 10 is generally held in the hand, and some operations are performed by operating the moving member 20 to move relative to the fixing member 10.
[0063] The fixing member 10 is provided with a guide channel 131 extending from the proximal end to the distal end.
[0064] The movable member 20 is movably connected to the fixed member 10, and there is a guiding property between the movable member 20 and the fixed member 10, so that the movable member 20 can reciprocate between the first position and the second position along the guide channel 131 relative to the fixed member 10. Exemplarily, the fixed member 10 is provided with a component or structure with guiding ability such as a track or a groove arranged along the guide channel 131, and the movable member 20 is connected with the component or structure with guiding ability through itself or a slider arranged thereon, so that the movable member 20 can move along the guide channel 131. Exemplarily, part of the structure of the movable member 20 is located outside the fixed member 10 or exposed in the open structure of the fixed member 10, so that a person can apply a thrust to these parts of the movable member 20 along the extension direction of the guide channel 131 toward the far end or the proximal end, so that the movable member 20 can move between the first position and the second position.
[0065] The instrument part 30 is a slender part, and the proximal end of the instrument part 30 is fixedly connected to the moving part 20, and moves with the movement of the moving part 20. According to the needs of the operation, the instrument part 30 can be a stone removal basket or a blocking basket, a biopsy forceps, etc.
[0066] The container 40 has a closed space inside, in which glue is stored. The glue has a certain fluidity, so that it can seep out from the damaged part of the container 40 and remain in the guide channel 131 and at least partially adhere to the surface of the object including the inner side wall of the guide channel 131. The glue will solidify after being exposed to the environment for a period of time and adhere to the attached object. The container 40 is arranged on the moving path of the moving member 20, that is, at a position between the first position and the second position. When the moving member 20 moves to the first position, the container 40 will be pierced by the piercing member 50. Exemplarily, the container 40 can be made of elastic rubber or iron sheet.
[0067] The piercing member 50 is connected to the moving member 20, and its distal end is set as a sharp portion for piercing the container 40. The distal end of the piercing member 50 protrudes from the distal end surface of the moving member 20 toward the container 40, so that the moving member 20 can pierce the container 40 forward during the movement from the second position to the first position.
[0068] When the moving member 20 moves to the first position, the piercing member 50 can pierce the container 40, leaving a pierced portion on the container 40. The glue can flow out from the pierced portion on the container 40 into the guide channel 131.
[0069] Figure 2 and Figure 3 In the embodiment, the moving member 20 is between the first position and the second position, and the piercing member 50 has not pierced a position of the container 40. Figure 2 and Figure 3The position of continues to move distally relative to the fixing member 10 and eventually reaches the first position.
[0070] In this embodiment, a container 40 that can be punctured by a puncture member 50 is arranged on the moving path of the moving member 20 that drives the instrument member 30 to move. The puncture member 50 is arranged at the distal end of the moving member 20 so that the puncture member 50 has the ability to puncture the container 40 during operation. In this way, when the moving member 20 moves to the first position, the moving member 20 punctures the container 40 through the puncture member 50, so that the glue in the container 40 can flow into the guide channel 131 through the puncture site. After a period of time, the glue in the guide channel 131 solidifies to form an obstacle that hinders the movement of the moving member 20 or a glue structure that connects the inner wall of the guide channel 131 with the moving member 20, so that the operating instrument cannot be used normally. This measure limits the normal use time of the operating instrument, avoids repeated use of the operating instrument, and can better avoid the problem of cross infection caused by repeated use.
[0071] Exemplarily, glues with different curing times can be selected according to the type of surgical instrument. Specifically, for some surgical instruments used in shorter operations, glues with shorter curing times can be selected. For some surgical instruments used in longer operations, glues with longer curing times can be selected. Exemplarily, the curing time of the glue stored in the container 40 can be half an hour, 1 hour, 2 hours, etc. It should be noted that the curing time of the glue in the prior art can be controlled by adjusting the components of the glue. Among them, the curing time refers to the interval between the moment when the glue seeps out of the container 40 and the moment when the glue solidifies to the point where it can hinder the movement of the moving part 20 so that the operating instrument cannot be used normally.
[0072] According to some optional embodiments, a guide channel 131 is provided inside the fixing member 10, and the guide channel 131 is set as a hole. The contour of the moving member 20 is adapted to the contour of the guide channel 131, and is inserted into the guide channel 131, and slides through its own peripheral wall and the inner side wall of the guide channel 131. The moving member 20 is guided and matched with the guide channel 131 by plugging itself with the shaft hole, and its structure is relatively simple, and the movement of the moving member 20 is relatively stable.
[0073] According to some optional embodiments, Figure 4 and Figure 5As shown, the peripheral wall of the moving part 20 is provided with a first guide groove 2111, the first guide groove 2111 has a certain length in the extension direction of the guide channel 131, and the distal end of the first guide groove 2111 is set to an opening, and the opening is formed on the distal end surface of the moving part 20, so that part of the glue flowing into the guide channel 131 can be transferred to the position between the outer periphery of the moving part 20 and the inner side wall of the guide channel 131 through the first guide groove 2111. After solidification, the glue entering the first guide groove 2111 can form a bonding structure between the outer periphery of the moving part 20 and the inner side wall of the guide channel 131, and the two are bonded to each other in the lateral direction, which can more reliably fix the moving part 20 and the fixed part 10, and effectively reduce the possibility of being reused.
[0074] The number of the first guide groove 2111 can be one or multiple mutually disconnected grooves. Figure 5 In the case of multiple channels, all the first guide grooves 2111 are arranged in sequence and equidistantly along the axial direction of the moving member 20, so that the glue can be evenly transferred between the outer periphery of the moving member 20 and the inner wall of the guide channel 131.
[0075] Preferably, Figure 5 As shown, the peripheral wall of the moving member 20 is further provided with a second guide groove 2112, and both ends of the second guide groove 2112 are located between the proximal end and the distal end of the moving member 20. At least one end of the second guide groove 2112 is laterally connected to the first guide groove 2111 to more evenly transfer the glue entering the first guide groove 2111 to a position between the outer periphery of the moving member 20 and the inner side wall of the guide channel 131.
[0076] Exemplarily, the second guide groove 2112 is configured as Figure 5 The circumferentially extending groove shown in the figure can also be set as a groove extending spirally along the peripheral wall of the movable member 20. Of course, when multiple second guide grooves 2112 are provided, they can also include both circumferentially extending grooves and spirally extending grooves.
[0077] Exemplarily, the end of the second guide groove 2112 may be laterally connected to the middle section of the first guide groove 2111 , or may be laterally connected to the proximal end of the first guide groove 2111 . Figure 5 In the illustrated situation, ends of some second guide grooves 2112 are laterally connected to the middle section of the first guide groove 2111 , and ends of other second guide grooves 2112 are laterally connected to the proximal end of the first guide groove 2111 .
[0078] In some embodiments, both ends of the second guide groove 2112 are laterally connected to the first guide groove 2111. When the first guide groove 2111 is one channel, both ends of the second guide groove 2112 are connected to the first guide groove 2111 from both sides of the first guide groove 2111, and when the first guide groove 2111 is multiple channels, both ends of the second guide groove 2112 are laterally connected to different first guide grooves 2111.
[0079] In some embodiments, such as Figure 5 As shown, the peripheral wall of the moving member 20 is provided with a plurality of first guide grooves 2111 arranged in sequence and at equal intervals along the circumferential direction, and is also provided with a plurality of second guide grooves 2112, all of which are arranged in a row in the circumferential direction and in the axial direction, and the ends of some second guide grooves 2112 are laterally connected to the middle section of the first guide groove 2111, and the ends of some second guide grooves 2112 are laterally connected to the proximal end of the first guide groove 2111. The ends of the second guide grooves 2112 located at the same axial position are circumferentially connected to each other through the first guide groove 2111.
[0080] When the first guide groove 2111 and the second guide groove 2112 are simultaneously provided on the peripheral wall of the movable part 20, the second guide groove 2112 acts as a branch to transfer the glue entering the first guide groove 2111 more evenly to the position between the outer periphery of the movable part 20 and the inner wall of the guide channel 131, so that a bonding structure can be formed on a wider surface, making the bonding fixation of the movable part 20 and the fixed part 10 more reliable.
[0081] According to some optional embodiments, Figure 4 As shown, the moving member 20 includes a push rod 21 and an operating handle 22 connected to the proximal end of the push rod 21 , and the push rod 21 is inserted into the axial hole of the guide channel 131 to achieve sliding fit.
[0082] In some embodiments, Figure 1 and Figure 2 As shown, a window 111 exposing the side of the guide channel 131 is formed on the peripheral wall of the fixing member 10 . The window 111 extends along the extending direction of the guide channel 131 , and a portion of the operating handle 22 extends from the window 111 to the outside of the fixing member 10 .
[0083] Preferably, the portion of the operating handle 22 located outside the fixing member 10 is formed with a casing surrounding the fixing member 10, and movable finger rings 221 for placing the index finger and the middle finger are respectively arranged on opposite sides of the casing. The movable finger ring 221 can be a closed ring or a Figure 4 The open ring structure shown in .
[0084] Preferably, a fixing finger ring 112 for inserting a thumb is provided at the proximal end of the fixing member 10 , so that a person can conveniently operate the fixing member 10 and the moving member 20 with one hand.
[0085] In other embodiments, the operating handle 22 extends proximally along the axial direction of the push rod 21 through the guide channel 131 to the outside of the fixing member 10, similar to the structure of the syringe and the push rod piston of a common medical syringe.
[0086] According to some optional embodiments, Figure 2 and Figure 3 As shown, a protective tube 80 is fixed in the fixing member 10, the distal end of the protective tube 80 is fixed to the fixing member 10, and the instrument member 30 is inserted into the protective tube 80. The distal end of the protective tube 80 is fixed and sealed to the fixing member 10 so that the glue cannot enter the protective tube 80 from the distal end of the protective tube 80, and the proximal end of the protective tube 80 is closer to the proximal end of the fixing member 10 than the proximal end of the container 40, so as to better prevent the glue entering the guide channel 131 from entering the protective tube 80 from the proximal end of the protective tube 80 and adhering to the instrument member 30.
[0087] Exemplarily, the protection tube 80 can be a hose or a hard tube.
[0088] In some embodiments, the proximal end of the protection tube 80 extends along the extension direction of the guide channel 131 to a through hole opened in the center of the push rod 21 of the moving member 20 .
[0089] According to some optional embodiments, Figure 3 As shown, the movable member 20 is provided with an exhaust passage 213, the distal opening of the exhaust passage 213 is formed on the distal surface of the movable member 20, and the exhaust passage 213 extends toward the proximal end, and the space in front of the distal surface of the movable member 20 where the guide channel 131 is located is communicated with the environment. The movable member 20 can be exhausted smoothly when advancing toward the distal end, and can be replenished smoothly when retreating toward the proximal end, to ensure that the movable member 20 can move smoothly.
[0090] According to some optional embodiments, Figure 7 As shown, the piercing member 50 is configured as a needle tube, and its head is obliquely cut to form an oblique cut 51 extending along the axial direction, so that when the piercing member 50 pierces the container 40, the glue can be smoothly discharged through the portion of the oblique cut that has not been inserted into the container 40 in a process.
[0091] According to some optional embodiments, Figure 1 - Figure 3As shown, the distal end of the fixing member 10 is fixedly connected to the proximal end of a flexible catheter 60, and the instrument member 30 is inserted into the catheter 60. When the instrument member 30 is not in use, the distal end of the instrument member 30 is completely located in the catheter 60. The instrument member 30 can extend or retract into the catheter 60 as the moving member 20 moves. When the instrument member 30 is needed to complete the relevant surgical operation, the moving member 20 is required to push the instrument member 30 out of the catheter 60. When the moving member 20 is in the second position, the distal end of the instrument member 30 is located in the catheter 60, and when the moving member 20 is in the first position, the distal end of the instrument member 30 is located outside the catheter 60. Figure 1 and Figure 2 As shown, the moving member 20 is located between the second position and the first position, and the distal end of the instrument member 30 now extends out of the catheter 60 .
[0092] According to some optional embodiments, Figure 3 - Figure 6 As shown, the container 40 is configured as an annular capsule, which is disposed around the instrument 30 to provide a larger glue storage capacity when space is limited. The container 40 can be a closed annular capsule to provide a complete annular cavity to store the glue, or it can be a closed annular capsule to provide a complete annular cavity to store the glue. Figure 6 The open annular capsule shown in FIG.
[0093] In some embodiments where a protective tube 80 is provided, Figure 3 As shown, the container 40 is surrounded by a protective tube 80 .
[0094] According to some optional embodiments, a plurality of puncture members 50 are connected to the moving member 20 so as to create a plurality of puncture sites on the container 40 so that the glue can flow out smoothly.
[0095] In some embodiments where the container 40 is configured as an annular capsule, all the piercing members 50 are sequentially arranged around the instrument member 30 .
[0096] Preferably, Figure 3 - Figure 6 As shown, the container 40 is supported by the mounting frame 70 to maintain its shape. The mounting frame 70 is a flange-type part, including a barrel portion 71 and a flange portion 72 disposed at the distal end of the barrel portion 71. The barrel portion 71 is inserted into the middle hole of the annular container 40 and supports the inner peripheral wall of the container 40 through the outer peripheral wall, and the proximal end surface of the flange portion 72 supports the distal end surface of the container 40. The mounting frame 70 maintains the shape of the circumference of the container 40 through the barrel portion 71 and the flange portion 72, which can well prevent the inward contraction of the container 40 from affecting the movement of the instrument 30.
[0097] According to some optional embodiments, the distal end of the container 40 abuts against the fixing member 10 in the extension direction of the guide channel 131, so that the container 40 is positioned at a certain position on the moving path of the moving member 20. When the container 40 is at this position and the moving member 20 moves to the first position, the moving member 20 compresses the container 40 along the extension direction of the guide channel 131, so that the container 40 is flattened to a certain extent, so that the glue in the container 40 can be squeezed out more before the moving member 20 moves to the first position.
[0098] According to some optional embodiments, Figure 2 and Figure 3 As shown, the fixing member 10 includes a cylinder 11, an end cap 12 and an inner sleeve 13. The inner sleeve 13 is inserted into the cylinder 11, and the end cap 12 is screwed and fixed to the distal end of the cylinder 11, and the inner sleeve 13 is pressed and fixed at the distal end of the cylinder 11. A stepped through hole is provided in the inner sleeve 13, and the stepped through hole provides a guide channel 131. The container 40 is stopped on the step surface of the stepped through hole. The moving member 20 is movably inserted in the inner sleeve 13 and slidably cooperates with the guide channel 131. The proximal end of the instrument member 30 passes through the end cap 12 and the inner sleeve 13 in sequence and is fixedly connected to the moving member 20.
[0099] In some embodiments, such as Figure 2 As shown, a window 111 exposing the side of the guide channel 131 is formed on the peripheral wall of the cylinder 11 , and the window 111 extends along the extending direction of the guide channel 131 .
[0100] In some embodiments, the fixing finger ring 112 is disposed at the distal end of the barrel 11 .
[0101] According to some optional embodiments, Figure 2 - Figure 5 As shown, the moving member 20 includes a push rod 21 and an operating handle 22 detachably mounted on the proximal end of the push rod 21. The piercing member 50 is fixedly connected to the distal end of the push rod 21.
[0102] In some embodiments, the push rod 21 is movably inserted into the guide channel 131 inside the inner sleeve 13. Part of the operating handle 22 passes through the window 111 provided in the cylinder body 11.
[0103] In some embodiments, the outer peripheral wall at the distal end of the push rod 21 is provided with the first guide groove 2111 alone or with the first guide groove 2111 and the second guide groove 2112 at the same time.
[0104] Preferably, Figure 5 - Figure 8As shown, the push rod 21 includes a detachable rod body 211 and an end cap 212. The outer peripheral wall of the push rod 21 is provided with a first guide groove 2111 alone or with both the first guide groove 2111 and the second guide groove 2112. A center hole 2113 is provided at the center of the push rod 21. The end cap 212 is screwed into the center hole 2113 of the rod body 211, and the distal end surface of the end cap 212 is flush with the distal end surface of the rod body 211. The piercing member 50 is inserted through the end cap 212 and fixed.
[0105] like Figure 3 As shown, the middle of the central hole 2113 has a tapered section that gradually shrinks from the distal end to the proximal end, so that the diameter of the section of the central hole 2113 located in front of the tapered section is larger than the diameter of the section located behind the tapered section. The protective tube 80 is inserted into the central hole 2113, and the distal end of the protective tube 80 is inserted into a section of the central hole 2113 with a smaller diameter.
[0106] In some embodiments, the protection tube 80 passes through a through hole provided at the center of the end cover 212 and contacts the hole wall to achieve dynamic sealing.
[0107] According to some optional embodiments, Figure 3 As shown, the push rod 21 is provided with an exhaust passage 213. The distal end opening of the exhaust passage 213 is located on the distal end surface of the push rod 21, and the exhaust passage 213 extends along the push rod 21 from the distal end surface to the proximal end surface and penetrates the push rod 21.
[0108] In some embodiments, the exhaust passage 213 provided on the push rod 21 of the moving member 20 is composed of a center hole 2113 provided on the rod body 211 and a vent hole 2121 provided in the end cap 212. The center hole 2113 penetrates the rod body 211, and the distal end of the center hole 2113 is screwed to the end cap 212 through an internal thread. The vent hole 2121 penetrates the end cap 212 from the distal end surface to the proximal end surface, the proximal end opening of the vent hole 2121 is communicated with the center hole 2113, and the distal end opening of the vent hole 2121 is formed on the distal end surface of the end cap 212 as the distal end opening of the exhaust passage 213.
[0109] In addition to the case where only one vent hole 2121 is provided on the end cover 212, a plurality of vent holes 2121 may also be provided. Figure 7-10 As shown, the plurality of vent holes 2121 on the end cover 212 are arranged in sequence along the axial direction of the end cover 212 .
[0110] In this embodiment, the distal opening of the exhaust channel 213 is formed on the distal surface of the moving member 20, and the exhaust channel 213 extends toward the proximal end, connecting the space of the guide channel 131 located in front of the distal surface of the moving member 20 with the environment. The moving member 20 can smoothly exhaust gas when moving forward toward the distal end, and can smoothly replenish gas when moving backward toward the proximal end, so as to ensure that the moving member 20 can move smoothly.
