[0036] This application embodiment also provides a medical device installation system, including a medical device installer and a medical device. The medical device installer is the medical device installer as described above. The medical device installer includes a main body and a connector. The main body and the connector are detachably connected. The connector is used to connect to the medical device. The main body is used to operate the medical device through the connector.

[0037] The main body includes a mounting hole extending along a first direction. One end of the mounting hole along the first direction has an opening for inserting the connector. At least one mounting groove is formed on the inner circumferential surface of the mounting hole. The mounting groove includes a first groove segment and a second groove segment that are interconnected. The first groove segment has a slot at one end near the opening. The first groove segment extends from the slot to the second groove segment. At least a portion of the second groove segment extends along the first direction.

[0038] The connector can move within the mounting hole along the first direction. The connector includes a connecting part and at least one first mounting part. The connecting part is used to connect to the medical device. The first mounting part can slide into the first slot and then into the second slot through the slot opening. The first mounting part can slide within the second slot along the first direction. The first mounting part can also slide from the second slot into the first slot and then slide out from the slot opening.

[0039] The main body also includes a limiting part located at one end of the second groove segment along the first direction, the limiting part being used to abut against the first mounting part to limit the sliding distance of the first mounting part within the second groove segment along the first direction.

[0040] The medical device installer provided in this application embodiment has a mounting hole extending along a first direction in its main body, with one end of the mounting hole having an opening for inserting a connector. At least one mounting groove is formed on the inner circumferential surface of the mounting hole, and the mounting groove includes at least a portion of a second groove segment extending along the first direction. Simultaneously, a connector for connecting a medical device can move within the mounting hole along the first direction, and a first mounting portion of the connector can slide within the second groove segment along the first direction.

[0041] After the connector is connected to the medical device and the main body operates the medical device to place it inside the human body through the connector, when the end of the main body away from the medical device is struck, the striking force will drive the main body to move relative to the connector in the first direction to the position where it abuts against the medical device, and transmit the striking force to the medical device to fix the medical device.

[0042] Since the connector can move relative to the main body along the first direction, it will not be subjected to impact force, which makes the connection between the connector and the medical device more stable and avoids the problem of deformation or damage to the connector at the connection point with the medical device due to impact force.

[0043] Based on this, the mounting groove further includes a first groove segment extending from the opening to the second groove segment, and the first mounting part of the connector can slide into the first groove segment through the groove and then into the second groove segment, and can slide along the first direction within the second groove segment. Simultaneously, the first mounting part of the connector can also slide from the second groove segment into the first groove segment and then slide out from the groove. Furthermore, the main body includes a limiting part located at one end of the second groove segment along the first direction, the limiting part abutting against the first mounting part to limit the sliding distance of the first mounting part along the first direction within the second groove segment, thereby preventing the first mounting part from dislodging from the second groove segment along the first direction.

[0044] Therefore, when the connector is installed from the opening into the mounting hole, the first mounting part can be slidably installed from the groove at one end of the first slot into the first slot, and then slide along the first slot into the second slot. This allows the connector to slide stably in the mounting hole along the first direction, and the limiting part abuts against the connecting part to prevent the connector from coming out of the mounting hole in the first direction, thus achieving a quick connection between the connector and the main body. When it is necessary to separate the connector from the main body, the first mounting part can be moved from the second slot to the first slot and then slid out from the groove of the first slot along the first direction, making the operation very convenient.

[0065] This application provides a medical device installer and a medical device installation system. These will be described in detail below.

[0066] First, this application provides a medical device installer.

[0067] Figure 1 This is a schematic diagram of the structure of the first embodiment of the medical device installer provided in this application. Figure 2 for Figure 1 A magnified view of point A in the middle. (See image below.) Figure 1 and Figure 2As shown, the medical device installer 1 includes a main body 10 and a connector 30. The main body 10 and the connector 30 are detachably connected. The connector 30 is used to connect to a medical device, and the main body 10 is used to operate the medical device (not shown in the figure) through the connector 30. Thus, the main body 10 and the connector 30 can be connected to each other, allowing the connector 30 to connect to the medical device. The main body 10 operates the medical device through the connector 30 to place the medical device on the human body or other locations. After use, the main body 10 and the connector 30 can be separated to facilitate sterilization of the medical device installer 1.

[0068] The medical device may include at least one of a mortising cup, a test cup, and an inner liner installer. The connecting part 33 can be used for threaded connection with the medical device to make the connection between the connecting part 33 and the medical device more convenient and stable.

[0069] Please refer to Figures 1 to 4 The main body 10 may include a mounting hole 111 extending along a first direction X, with one end of the mounting hole 111 having an opening 1111 for inserting a connector 30. The connector 30 is mounted in the mounting hole 111 and is movable within the mounting hole 111 along the first direction X, thereby making the connector 30 detachably connected to the main body 10 and movable relative to the main body 10 along the first direction X.

[0070] Therefore, after the connector 30 is connected to the medical device and the main body 10 operates the medical device to be placed in the human body through the connector 30, when the end of the main body 10 away from the medical device is struck, the striking force will drive the main body 10 to move relative to the connector 30 in the first direction X to the position where it abuts against the medical device, and transmit the striking force to the medical device so as to fix the medical device.

[0071] Since the connector 30 can move relative to the main body 10 along the first direction X, the connector 30 will not be subjected to impact force, which makes the connection between the connector 30 and the medical device more stable and avoids the problem of deformation or damage to the connector 30 at the connection with the medical device due to impact force.

[0072] In some embodiments, at least one mounting groove 112 may be provided on the inner peripheral surface 116 of the mounting hole 111. The connector 30 includes a connecting part 33 and at least one first mounting part 32. The connecting part 33 is used to connect a medical device. The first mounting part 32 can slide into the mounting groove 112 and slide along the first direction X within a preset area of ​​the mounting groove 112, thereby making the connection between the connector 30 and the body 10 more stable.

[0073] The mounting groove 112 may include a second groove segment 1121, at least a portion of which extends along a first direction X. The first mounting portion 32 may slide within the second groove segment 1121 along the first direction X, so that when the connector 30 is installed into the mounting hole 111, the connector 30 may slide relative to the body 10 along the first direction X.

[0074] Continue to refer to Figure 1 The main body 10 also includes a limiting portion 114 located at one end of the second groove segment 1121 along the first direction X. The limiting portion 114 is used to abut against the first mounting portion 32 to limit the sliding distance of the first mounting portion 32 within the second groove segment 1121 along the first direction X. Thus, the limiting portion 114 can prevent the first mounting portion 32 from sliding out of the second groove segment 1121 along the first direction X, thereby preventing the connector 30 from dislodging from the mounting hole 111 along the first direction X, making the connection between the connector 30 and the main body 10 more stable.

[0075] The limiting portion 114 can be part of the main body 10. Specifically, the second groove segment 1121 and the opening 1111 are spaced apart so that the limiting portion 114 is formed at one end of the second groove segment 1121 along the first direction X.

[0076] In some embodiments, the mounting groove 112 may include a first groove segment 1122 and a second groove segment 1121 that are interconnected. The first groove segment 1122 has a notch 1125 at one end near the opening 1111, and the first groove segment 1122 extends from the notch 1125 to the second groove segment 1121. The first mounting portion 32 of the connector 30 can slide into the first groove segment 1122 and then into the second groove segment 1121 through the notch 1125, and the first mounting portion 32 can also slide into the first groove segment 1122 from the second groove segment 1121 and then slide out from the notch 1125.

[0077] The medical device installer 1 provided in this application embodiment has a mounting hole 111 extending along a first direction X in the main body 10. One end of the mounting hole 111 along the first direction X has an opening 1111 for inserting a connector 30. At least one mounting groove 112 is formed on the inner peripheral surface 116 of the mounting hole 111, and the mounting groove 112 includes at least a portion of a second groove segment 1121 extending along the first direction X. At the same time, the connector 30 used to connect the medical device can move along the first direction X within the mounting hole 111, and the first mounting portion 32 of the connector 30 can slide along the first direction X within the second groove segment 1121.

[0078] After the connector 30 is connected to the medical device and the main body 10 operates the medical device to be placed in the human body through the connector 30, when the end of the main body 10 away from the medical device is struck, the striking force will drive the main body 10 to move relative to the connector 30 in the first direction X to the position where it abuts against the medical device, and transmit the striking force to the medical device so as to fix the medical device.

[0079] Since the connector 30 can move relative to the main body 10 along the first direction X, the connector 30 will not be subjected to impact force, which makes the connection between the connector 30 and the medical device more stable and avoids the problem of deformation or damage to the connector 30 at the connection with the medical device due to impact force.

[0080] Based on this, the mounting groove 112 further includes a first groove segment 1122 extending from the opening 1111's groove 1125 to the second groove segment 1121, and the first mounting portion 32 of the connector 30 can slide into the first groove segment 1122 through the groove 1125 and then into the second groove segment 1121, and can slide along the first direction X within the second groove segment 1121. Simultaneously, the first mounting portion 32 of the connector 30 can also slide from the second groove segment 1121 into the first groove segment 1122 and then slide out through the groove 1125. Furthermore, the main body 10 also includes a limiting portion 114 located at one end of the second groove segment 1121 along the first direction X. The limiting portion 114 abuts against the first mounting portion 32 to limit the sliding distance of the first mounting portion 32 along the first direction X within the second groove segment 1121, thereby preventing the first mounting portion 32 from dislodging from the second groove segment 1121 along the first direction X.

[0081] Therefore, when the connector 30 is installed from the opening 1111 into the mounting hole 111, the first mounting part 32 can be slidably installed from the slot 1125 at one end of the opening 1111 into the first slot 1122, and then slide along the first slot 1122 into the second slot 1121. This allows the connector 30 to slide stably along the first direction X within the mounting hole 111. Furthermore, the limiting part 114 abuts against the connecting part 33 to prevent the connector 30 from dislodging from the mounting hole 111 along the first direction X, thus achieving a quick connection between the connector 30 and the main body 10. When it is necessary to separate the connector 30 from the main body 10, the first mounting part 32 can be moved from the second slot 1121 to the first slot 1122 and then slide out from the slot 1125 of the first slot 1122 along the first direction X. The operation is very convenient.

[0082] In some embodiments, such as Figure 4As shown, the medical device installer 1 may further include an elastic member 40 connected to the main body 10. This elastic member 40 is connected to the connector 30 and is used to drive the connector 30 to move along the first direction X. Thus, the elastic member 40 can keep the connector 30 in the position where the first mounting portion 32 abuts against the limiting portion 114, which helps to maintain a stable relative position between the connector 30 and the main body 10. Furthermore, the elastic member 40 can also prevent the connector 30 from moving in the opposite direction X, thereby reducing the risk of the connector 30 dislodging from the mounting hole 111.

[0083] Specifically, the elastic element 40 is disposed within the mounting hole 111. The connector 30 is located on one side of the elastic element 40 along the first direction X. One end of the elastic element 40 along the first direction X abuts against the connector 30. The other end of the elastic element 40 along the opposite direction X abuts against the inner surface of the mounting hole 111. The elastic element 40 can be a spring, rubber, or other component capable of applying an elastic force to the connector 30, causing the connector 30 to move along the first direction X; no limitation is made here.

[0084] like Figure 3 As shown, the first slot segment 1122 may include a first sub-slot segment 1124 and a second sub-slot segment 1123 connected in sequence. The second sub-slot segment 1123 includes a first end 1126 and a second end 1127 opposite to each other. The first sub-slot segment 1124 extends from the slot opening 1125 to the first end 1126 of the second sub-slot segment 1123. The second end 1127 of the second sub-slot segment 1123 is connected to the second slot segment 1121, thereby allowing the first slot segment 1122 to extend from the slot opening 1125 to the second slot segment 1121 and to be connected to the second slot segment 1121.

[0085] The first sub-slot segment 1124 and the second sub-slot segment 1121 can be sequentially distributed along the circumference of the mounting hole 111 to reduce the risk that the first mounting part 32 will move from the second sub-slot segment 1121 to the first sub-slot segment 1122 after the connector 30 is pushed or impacted by an external force, and slide out from the slot 1125 of the first sub-slot segment 1122 along the first direction X, causing the connector 30 to come out of the mounting hole 111.

[0086] The first sub-slot segment 1124 and the second sub-slot segment 1121 can be approximately parallel or at a certain angle, as long as the first mounting part 32 can enter the first sub-slot segment 1124 through the slot 1125, slide through the second sub-slot segment 1123, and enter the second sub-slot segment 1121. Of course, the parallelism of the first sub-slot segment 1124 and the second sub-slot segment 1121 allows the first mounting part 32 to more easily slide into the first sub-slot segment 1122 from the slot 1125 at the opening 1111 end of the first sub-slot segment 1122, and then slide along the first sub-slot segment 1122 into the second sub-slot segment 1121. This also makes the processing of the first sub-slot segment 1124 more convenient.

[0087] In some embodiments, in the first direction X, the distance from the first end 1126 of the second sub-slot segment 1123 to the opening 1111 can be greater than or equal to the distance from the second end 1127 of the second sub-slot segment 1123 to the opening 1111, thereby reducing the risk that the first mounting portion 32 will move from the second slot segment 1121 to the first slot segment 1122 after the connector 30 is pushed or impacted by an external force, and slide out from the slot opening 1125 of the first slot segment 1122 along the first direction X, causing the connector 30 to come out of the mounting hole 111.

[0088] Understandably, since the distance from the first end 1126 of the second sub-slot 1123 along the first direction X to the opening 1111 is greater than or equal to the distance from the second end 1127 of the second sub-slot 1123 along the first direction X to the opening 1111, when the first mounting part 32 moves from the second sub-slot 1121 to the first sub-slot 1122 and slides out from the slot 1125 of the first sub-slot 1122 along the first direction X, the first mounting part 32 needs to move a certain distance in the second sub-slot 1123 in the opposite direction of the first direction X. In this way, the first mounting part 32 is less likely to slide from the second sub-slot 1123 to the first sub-slot 1124, which can reduce the risk of the first mounting part 32 entering the first sub-slot 1124 from the second sub-slot 1123 and sliding out from the slot 1125 of the first sub-slot 1122.

[0089] In some embodiments, in the first direction X, the maximum distance from the second sub-slot segment 1123 to the opening 1111 can be greater than the maximum distance from the second end 1127 to the opening 1111, thereby reducing the risk that after the connector 30 is pushed or impacted by an external force, the first mounting part 32 moves from the second slot segment 1121 to the first slot segment 1122 and slides out from the slot opening 1125 of the first slot segment 1122 along the first direction X, causing the connector 30 to come out of the mounting hole 111.

[0090] Understandably, since the maximum distance from the second sub-slot segment 1123 along the first direction X to the opening 1111 is greater than the distance from the second end 1127 of the second sub-slot segment 1123 along the first direction X to the opening 1111, when the first mounting part 32 moves from the second sub-slot segment 1121 to the first sub-slot segment 1122 and slides out from the slot opening 1125 of the first sub-slot segment 1122 along the first direction X, the first mounting part 32 needs to move a certain distance in the second sub-slot segment 1123 in the opposite direction of the first direction X. In this way, the first mounting part 32 is less likely to slide from the second sub-slot segment 1123 to the first sub-slot segment 1124, which can reduce the risk of the first mounting part 32 entering the first sub-slot segment 1124 from the second sub-slot segment 1123 and sliding out from the slot opening 1125 of the first sub-slot segment 1122.

[0091] In some embodiments, a plurality of mounting grooves 112 may be formed on the inner circumferential surface 116 of the mounting hole 111, and the plurality of mounting grooves 112 are distributed sequentially along the circumference of the mounting hole 111. Correspondingly, the connector 30 includes a plurality of first mounting portions 32, which are slidably mounted one-to-one in the plurality of mounting grooves 112. This makes the connection between the connector 30 and the body 10 more stable, and helps to further reduce the risk of the connector 30 coming out of the mounting hole 111.

[0092] In some embodiments, when the first mounting part 32 slides in the first groove segment 1122, the connector 30 can rotate within the mounting hole 111 about a rotation axis X1, which extends along a first direction X. It is understood that when the first mounting part 32 slides from the first groove segment 1122 to the second groove segment 1121, the first mounting part 32 will rotate a certain angle in the circumferential direction of the mounting hole 111. By allowing the connector 30 to rotate within the mounting hole 111 about the rotation axis X1, the first mounting part 32 can slide more smoothly from the first groove segment 1122 to the second groove segment 1121 during the process of installing the connector 30 into the mounting hole 111.

[0093] like Figure 4 As shown, the connector 30 includes a connecting rod 31, one end of which is connected to the connecting portion 33 along the first direction X. The connecting rod 31 is slidably mounted in the mounting hole 111 along the first direction X, so that the connector 30 is slidably mounted in the mounting hole 111 along the first direction X. At least one first mounting portion 32 may be provided on the outer peripheral surface of the connecting rod 31 so that the first mounting portion 32 can be inserted into the mounting groove 112.

[0094] Specifically, the radial cross-section of the connecting rod 31 can be circular, allowing it to rotate around the rotation axis X1 within the mounting hole 111. Correspondingly, the radial cross-section of the mounting hole 111 can also be circular, making the shape of the mounting hole 111 more compatible with that of the connecting rod 31, which helps improve the installation stability of the connecting rod 31.

[0095] The pin can be made to pass through the connecting rod 31 radially, and a portion of the pin can extend out of the outer peripheral surface of the connecting rod 31 to form a first mounting portion 32 protruding from the outer peripheral surface of the connecting rod 31. Alternatively, both ends of the pin can extend out of the outer peripheral surface of the connecting rod 31 to form the first mounting portion 32 on both radial sides of the connecting rod 31.

[0096] like Figures 1 to 4As shown, one end of the main body 10 is provided with a second mounting portion 11, which includes an outer peripheral surface 115 and an inner peripheral surface 116, with the inner peripheral surface 116 forming a mounting hole 111. In some embodiments, a mounting groove 112 can extend from the inner peripheral surface 116 of the second mounting portion 11 to the outer peripheral surface 115, that is, the mounting groove 112 passes through the inner wall of the mounting hole 111, thereby making the processing of the mounting groove 112 more convenient.

[0097] Specifically, the main body 10 is a rod-shaped structure extending along the first direction X. The second mounting portion 11 is located at one end of the main body 10 along the first direction X. The opening 1111 of the mounting hole 111 is located at one end of the second mounting portion 11 along the first direction X. The first groove segment 1122 and the second groove segment 1121 of the mounting groove 112 both extend from the inner peripheral surface 116 of the second mounting portion 11 to the outer peripheral surface 115, that is, the first groove segment 1122 and the second groove segment 1121 of the mounting groove 112 both penetrate the inner wall of the mounting hole 111 radially along the mounting hole 111.

[0098] In other embodiments, such as Figure 5 As shown, the bottom surface of the mounting groove 112 can also be spaced apart from the outer peripheral surface 115 of the second mounting portion 11. That is, the mounting groove 112 extends from the inner peripheral surface 116 of the second mounting portion 11 to the outer peripheral surface 115, but the mounting groove 112 does not extend to the outer peripheral surface 115 of the second mounting portion 11, and the mounting groove 112 does not penetrate the inner wall of the mounting hole 111. This helps to improve the structural strength of the second mounting portion 11. When the end of the main body 10 away from the medical device is struck, the striking force will drive the second mounting portion 11 of the main body 10 to move relative to the connector 30 in the first direction X to the position abutting against the medical device, and stably transmit the striking force to the medical device, so as to fix the medical device.

[0099] In other embodiments, such as Figure 6 As shown, a second mounting portion 11 is provided at one end of the main body 10. The second mounting portion 11 includes an outer peripheral surface 115 and an inner peripheral surface 116, which enclose a mounting hole 111. A mounting groove 112 extends from the inner peripheral surface 116 to the outer peripheral surface 115. A sheath 20 is fitted onto the outer peripheral surface 115 of the second mounting portion 11, covering at least a portion of the mounting groove 112. Thus, when the end of the main body 10 furthest from the medical device is struck, the sheath 20 can withstand a portion of the impact force and transmit it to the medical device, thereby reducing the impact force on the second mounting portion 11 and lowering the risk of deformation of the second mounting portion 11.

[0100] The sheath 20 and the second mounting part 11 can be connected together by means of snap-fit, welding, or pasting, and no restrictions are imposed here.

[0101] In some embodiments, a protrusion 113 may be provided on the outer peripheral surface 115 of the second mounting portion 11, and the sheath 20 is located on one side of the protrusion 113 along the first direction X, with the protrusion 113 abutting against the sheath 20 along the first direction X. Thus, when the end of the main body 10 away from the medical device is struck, the main body 10 can stably transmit a portion of the striking force to the sheath 20 through the protrusion 113.

[0102] like Figure 3 As shown, when the limiting part 114 abuts against the first mounting part 32, the length of the part of the connecting part 33 extending out of the mounting hole 111 in the first direction X is L1, and the length of the second groove segment 1121 in the first direction X is L2. In some embodiments, L1≤L2 can be made to reduce the risk that the connecting head 30 will come out of the mounting hole 111 after being pushed or hit by an external force.

[0103] It is understandable that when the connector 30 is pushed or hit by a human hand or other foreign object, the foreign object pushes the connector 30 to move in the opposite direction of the first direction X until the foreign object and the end face of the body 10 in the first direction X come into contact. The distance that the connector 30 moves in the opposite direction of the first direction X is L1. The body 10 will prevent the foreign object from continuing to move in the opposite direction of the first direction X.

[0104] Since the length L1 of the portion of the connecting part 33 extending out of the mounting hole 111 in the first direction X is less than or equal to the length L2 of the second groove segment 1121 in the first direction X, the first mounting part 32 is still inside the second groove segment 1121 and is not easy to slide from the second groove segment 1121 to the first groove segment 1122 and disengage from the groove opening 1125. Therefore, it is beneficial to reduce the risk of the connector 30 disengaging from the mounting hole 111.

[0105] In some embodiments, such as Figure 2 As shown, a disassembly groove 311 can be provided on the end face of the connecting part 33 along the first direction X. The disassembly groove 311 is used for inserting a disassembly tool and driving the connecting head 30 to move by the disassembly tool, so as to drive the first mounting part 32 to slide between the first groove segment 1122 and the second groove segment 1121.

[0106] Therefore, by inserting a disassembly tool into the disassembly groove 311 of the connecting part 33, a driving force can be easily applied to the connecting part 33, thereby driving the connector 30 to move. This allows the first mounting part 32 to slide from the groove 1125 at one end of the opening 1111 of the first groove segment 1122 into the first groove segment 1122, and then slide along the first groove segment 1122 into the second groove segment 1121, thus enabling the connector 30 to slide stably along the first direction X within the mounting hole 111. Alternatively, the first mounting part 32 can be moved from the second groove segment 1121 to the first groove segment 1122, and then slide out from the groove 1125 of the first groove segment 1122 along the first direction X, separating the connector 30 from the main body 10. The operation is very convenient.

[0107] The disassembly tool can be a screwdriver or other tool that can be inserted into the disassembly slot 311 and push the connecting part 33 to move in the opposite direction of the first direction X. There are no restrictions on this.

[0108] In some embodiments, such as Figures 7 to 9 As shown, the medical device installer 1 may further include an abutment 50 sleeved on the connecting portion 33, the abutment 50 being located on one side of the main body 10 along the first direction X. One end of the abutment 50 along the first direction X is used to abut against the medical device.

[0109] Therefore, when the end of the main body 10 furthest from the medical device is struck, the main body 10 can transmit the striking force to the abutment 50, and then to the medical device through the abutment 50. Furthermore, the abutment 50 limits the distance that an external object can push the connector 30 to move in the opposite direction of the first direction X, thus reducing the risk of the connector 30 dislodging from the mounting hole 111. In addition, when the abutment 50 is damaged, replacement is easier, reducing the operating cost of the medical device installer 1. Moreover, when the rigidity of the abutment 50 is lower than that of the main body 10, the abutment 50 can provide a certain degree of cushioning, reducing the risk of damage to the medical device under the impact force.

[0110] Finally, for different specifications of medical devices, the shape and size of the force-bearing surface used to withstand the impact force will vary. The medical device installer 1 includes an abutment member 50 that can be fitted onto the connecting part 33, with one end of the abutment member 50 along the first direction X used to abut against the medical device. When using the medical device installer 1, the abutment member 50 can be replaced with the corresponding abutment member 50 for different specifications of medical devices, so that the shape of the abutment member 50 is more compatible with the medical device, thereby more stably transmitting the impact force to the medical device.

[0111] In some embodiments, the abutment 50 may have a through hole 51 extending in the first direction X, through which the connector 30 passes, allowing the connector 30 to slide relative to the abutment 50 in the first direction X. Thus, when the body 10 transmits a striking force to the abutment 50, and ultimately to the medical device via the abutment 50, the connector 30 will not bear the striking force from the abutment 50, preventing deformation or damage to the connector 30 at the connection point with the medical device due to the impact of the striking force.

[0112] In other embodiments, such as Figure 12 As shown, the abutment 50 can also be threaded onto the connecting portion 33. This helps reduce the risk of the connector 30 coming out of the mounting hole 111. Moreover, when the connecting portion 33 is connected to the medical device, one end of the abutment 50 can abut against the medical device, and the other end of the abutment 50 can abut against the body 10. This allows the body 10 to transmit the impact force to the medical device through the abutment 50, which helps reduce the impact force borne by the connector 30 at the connection point with the medical device, thereby reducing the risk of deformation or damage to the connector 30 at the connection point with the medical device.

[0113] In some embodiments, the abutment 50 can be detachably connected to the main body 10. This makes it easier to replace the abutment 50. It also makes it easier to install and remove the connector 30.

[0114] The abutment 50 can be snapped into the main body 10 to make the connection and separation of the abutment 50 and the main body 10 more convenient.

[0115] In some embodiments, such as Figure 8 As shown, a first engaging portion 101 extends from one end of the main body 10 along the first direction X, and a second engaging portion 52 is provided on the side of the abutment 50 near the main body 10. The first engaging portion 101 and the second engaging portion 52 engage to detachably connect the abutment 50 to the main body 10. Thus, when the abutment 50 is fitted onto the connector 30, the second engaging portion 52 of the abutment 50 engages with the first engaging portion 101 of the main body 10, allowing the abutment 50 to be detachably connected to the main body 10, which is convenient to operate.

[0116] In this configuration, a first slot 102 may be provided in the first latching portion 101, and the second latching portion 52 may be at least partially inserted into the first slot 102 to ensure a stable latching connection between the first latching portion 101 and the second latching portion 52. Alternatively, a second slot 521 may be provided in the second latching portion 52, and the first latching portion 101 may be at least partially inserted into the second slot 521 to ensure a stable latching connection between the first latching portion 101 and the second latching portion 52.

[0117] It should be noted that a first card slot 102 can be formed in the first card receiving portion 101, while a second card slot 521 can be formed in the second card receiving portion 52. Alternatively, a first card slot 102 can be formed only in the first card receiving portion 101, or a second card slot 521 can be formed only in the second card receiving portion 52. Of course, the former can further improve the card-connection stability of the first card receiving portion 101 and the second card receiving portion 52.

[0118] Specifically, such as Figure 8 and Figure 9 As shown, the first latching portion 101 protrudes from one side of the second mounting portion 11 along the first direction X. The first latching portion 101 extends circumferentially along the mounting hole 111. The first groove segment 1122 penetrates the first latching portion 101 along the first direction X. The first slot 102 is formed on the outer peripheral surface of the first latching portion 101. The first slot 102 extends circumferentially along the first latching portion 101.

[0119] The second latching portion 52 protrudes from the abutment member 50 on the side opposite to the first direction X. The second latching portion 52 extends circumferentially along the through hole 51. The second latching groove 521 is formed on the side of the second latching portion 52 facing the through hole 51. The second latching groove 521 extends circumferentially along the through hole 51.

[0120] In some embodiments, such as Figure 10 and Figure 11 As shown, a first groove 103 may be provided in the first latching portion 101, and a second groove 522 may be provided in the second latching portion 52. The medical device installer 1 also includes a retaining member 60, a part of which is located in the first groove 103 and the other part of which is located in the second groove 522, so that the first latching portion 101 and the second latching portion 52 are stably latched together.

[0121] Specifically, the first latching portion 101 protrudes from one side of the second mounting portion 11 along the first direction X. The first latching portion 101 extends circumferentially along the mounting hole 111. The first groove segment 1122 penetrates the first latching portion 101 along the first direction X. The first groove 103 is formed on the outer peripheral surface of the first latching portion 101. The first groove 103 extends circumferentially along the first latching portion 101.

[0122] The second engaging portion 52 protrudes from the abutment member 50 on the side opposite to the first direction X. The second engaging portion 52 extends circumferentially along the through hole 51. The second groove 522 is formed on the side of the second engaging portion 52 facing the through hole 51. The second groove 522 extends circumferentially along the through hole 51.

[0123] The retaining member 60 can be a retaining spring extending circumferentially along the first retaining portion. The retaining member 60 is retained within the first groove 103 of the first retaining portion. A portion of the retaining member 60 protrudes from the outer peripheral surface of the first retaining portion. When the second retaining portion moves relative to the first retaining portion in the opposite direction X to the first retaining portion to the position where the second groove 522 corresponds to the first groove 103, the portion of the retaining member 60 protruding from the outer peripheral surface of the first retaining portion is inserted into the second groove 522.

[0124] This application also provides a medical device installation system, which includes a medical device installer.
