[0099] Figure 1 An exploded view of a multi-channel poke card according to an embodiment of the present disclosure is schematically shown.

[0100] like Figure 1 As shown, a multi-channel poking card for a single-port surgical robot includes:

[0101] The card cover 100 is provided with a plurality of sockets in equal parts, and the sockets are configured to be inserted into medical devices;

[0102] A bottom tube 200 , which is adapted to detachably support the card cover 100 ;

[0103] The first opening and closing bracket 300 is overlapped on the inner wall of the bottom tube 200

[0104] A plurality of spring-type opening and closing pieces 310 are mounted on the first opening and closing bracket 300, with one spring-type opening and closing piece 310 corresponding to one socket. The spring-type opening and closing piece 310 includes:

[0105] A T-shaped rod 311 passes through the first opening and closing bracket 300 and the side wall of the bottom tube 200;

[0106] A pressure spring 312 is sleeved on the T-shaped rod 311 outside the bottom tube 200;

[0107] The arc-shaped opening and closing piece 313 is disposed inside the first opening and closing bracket 300 and is rotatably connected to the T-shaped rod 311 via a connecting shaft;

[0108] When the T-shaped rod 311 is pressed or released, the relative position between the arc-shaped opening and closing piece 313 and the socket is changed by the deformation of the pressure spring 312 .

[0109] According to an embodiment of the present disclosure, when installing the multi-channel puncture card, the first opening and closing bracket 300 equipped with multiple spring-type opening and closing pieces 310 is overlapped on the inner wall of the bottom tube 200, and the card cover 100 is detachably installed on the bottom tube 200.

[0110] According to an embodiment of the present disclosure, when starting an operation, an assistant (nurse or other non-surgeon) presses the T-shaped rod 311 to compress the pressure spring 312. At this time, the arc-shaped opening and closing piece 313 is separated from the bottom of the socket. The surgeon can insert the medical device into the socket corresponding to the T-shaped rod 311 and pass it through the bottom tube 200, thereby performing surgical operations on the patient.

[0111] According to the embodiments of the present disclosure, when a medical device needs to be removed from the punch card after surgery, due to the irregularities of the medical device inserted into the human body, such as the inconsistency of the lateral dimensions of multiple parts, if the spring-type opening and closing piece 310 of the present disclosure is not used and a conventional torsion spring-type opening and closing piece is used, a portion of the medical device may become stuck on the conventional torsion spring-type opening and closing piece when the medical device is removed, making it impossible to remove it smoothly. However, by using the spring-type opening and closing piece 310 of the present disclosure, the T-shaped rod 311 can be pressed continuously, so that the arc-shaped opening and closing piece 313 is always disengaged from the bottom of the socket, thereby smoothly removing the medical device inserted into the human body from the punch card.

[0112] According to the embodiments of the present disclosure, during surgery, the relative position of the arcuate opening and closing piece 313 and the socket can be changed by controlling the position of the T-shaped rod 311, thereby facilitating the insertion and removal of medical devices. This avoids the problem of interference between the medical device and the arcuate opening and closing piece 313 due to irregularities in the insertion of the medical device into the human body, preventing smooth removal from the puncture card, thereby improving the convenience and safety of the operation during surgery. At the same time, the detachable connection between the card cover 100, the bottom tube 200, and the first opening and closing bracket 300 facilitates the separation of the card cover 100 from the bottom tube 200 via the spring-loaded latch mechanism 210 after the surgery is completed, thereby facilitating the cleaning, disinfection, or replacement of the interior of the bottom tube 200 and its internal components, improving the cleaning efficiency of the multi-channel puncture card and reducing the surgical cost of replacing the entire multi-channel puncture card.

[0113] Figure 2 The schematic diagram of the structure of the spring-type opening and closing piece 310 according to an embodiment of the present disclosure is shown schematically.

[0114] According to the embodiments of the present disclosure, Figure 2 As shown, the arc-shaped opening and closing piece 313 includes:

[0115] An arc-shaped connecting rod 3131, one end of which is rotatably connected to the T-shaped rod 311 via a connecting shaft. One end of the T-shaped rod 311 located inside the first opening and closing bracket 300 is provided with a strip groove extending in the radial direction. The strip groove is rotatably connected to the arc-shaped connecting rod 3131 via the connecting shaft.

[0116] The opening and closing shaft 3132 passes through the arc-shaped connecting rod 3131 and is installed on the inner wall of the first opening and closing bracket 300 through a mounting seat;

[0117] The opening and closing piece 3133 is connected to the other end of the arc-shaped connecting rod 3131 at a preset angle. When the pressure spring 312 is not deformed, the opening and closing piece 3133 is located directly below the socket. When the pressure spring 312 is deformed, the opening and closing piece 3133 deviates from the position directly below the socket.

[0118] Among them, a through hole for inserting the T-shaped rod 311 is provided on the bottom tube 200, and a sliding groove is provided on the inner wall of the through hole. A sliding block that cooperates with the sliding groove is provided on the T-shaped rod 311. After pressing the T-shaped rod 311, the sliding block is disengaged from the sliding groove by rotating the T-shaped rod 311 to fix the position of the T-shaped rod 311.

[0119] According to an embodiment of the present disclosure, when the T-shaped rod 311 is pressed, the pressure spring 312 is compressed. At this time, the length of the T-shaped rod 311 inserted into the bottom tube 200 changes. Since the connecting shaft can slide in the strip groove, the angle of the arc-shaped connecting rod 3131 changes with the opening and closing rotating shaft 3132 as the center of the circle. As the length of the T-shaped rod 311 inserted into the bottom tube 200 gradually increases, the opening and closing piece 3133 connected to the arc-shaped connecting rod 3131 deviates from the bottom of the socket. At this time, the medical device can be inserted into the human body or the medical device can be removed from the puncture card.

[0120] According to an embodiment of the present disclosure, in order to avoid surgical risks caused by long-term human pressure on the T-shaped rod 311, for example, when the assistant loses strength while the operation is still in progress, if the assistant releases the T-shaped rod 311 at this time, the opening and closing piece 3133 may restrict the normal operation of the medical device, thereby causing surgical risks, the present disclosure limits the position of the T-shaped rod 311 through a sliding groove and a sliding block.

[0121] According to the embodiment of the present disclosure, the assistant presses the T-shaped rod 311, so that the sliding block slides toward the inside of the bottom tube 200 under the guidance of the sliding groove until the T-shaped rod 311 reaches the maximum stroke, and the sliding block disengages from the sliding groove. At this time, the T-shaped rod 311 can be rotated a smaller angle, so that the position of the sliding block does not correspond to the sliding groove. At this time, when the pressure spring 312 releases its elastic potential energy, the sliding block is squeezed against the inner wall of the bottom tube 200, thereby completing the position limit of the T-shaped rod 311. At this time, the medical device can be inserted or removed.

[0122] According to an embodiment of the present disclosure, the spring-loaded opening and closing piece 310 further includes an elastic sealing gasket 314, which is mounted on the T-shaped rod 311 between the pressure spring 312 and the outer wall of the first opening and closing bracket 300. The elastic sealing gasket 314 is used to ensure airtightness to prevent excessive gas from entering the human body.

[0123] Figure 3 The figure schematically shows a structure diagram of a multi-channel card separation state according to another embodiment of the present disclosure.

[0124] According to the embodiments of the present disclosure, Figure 3 As shown, a plurality of first supporting plates 110 are spaced apart at the edge of the card cover 100 , wherein the first supporting plates 110 are provided with first positioning holes 111 ;

[0125] The bottom pipe 200 further includes:

[0126] A plurality of spring latch mechanisms 210 are mounted on the outer wall of the bottom tube 200 . The spring latch mechanisms 210 are configured to cooperate with the first positioning holes 111 to fix the card cover 100 on the bottom tube 200 .

[0127] According to the embodiment of the present disclosure, the card cover 100 is connected to the bottom tube 200 by a spring-type latch mechanism 210. After the operation is completed, the card cover 100 can be separated from the bottom tube 200 by the spring-type latch mechanism 210, thereby facilitating the cleaning, disinfection or replacement of parts of the bottom tube 200 and the card cover 100, thereby improving the cleaning efficiency of the multi-channel puncture card and reducing the surgical cost of replacing the entire multi-channel puncture card. Figure 3 As shown, the bottom tube 200 further includes:

[0128] The pipe 220 is connected to the side of the bottom pipe 200 away from the card cover 100. The interior of the pipe 220 is divided into multiple fan-shaped sub-pipes 220 by a bifurcated bracket. Each sub-pipe 220 corresponds to a spring-loaded opening and closing piece 310. The pipe 220 is integrally formed with the main body 201 and is suitable for insertion into the human body.

[0129] The bottom pipe 200 includes:

[0130] A main body 201, wherein a receiving space is formed in the main body 201, and the receiving space is suitable for inserting a medical device;

[0131] The annular second support plate 202 is installed on the outer edge of one side of the main body 201 close to the card cover 100. The second support plate 202 is provided with a second positioning hole 203 that cooperates with the first positioning hole 111. The second positioning hole 203 is suitable for the spring-type latch mechanism 210 to be connected to the first positioning hole 111 through the second positioning hole 203.

[0132] According to an embodiment of the present disclosure, in order to facilitate the direct application of medical devices to the surgical site during surgery, a pipe 220 can be provided in the bottom tube 200. The pipe 220 can be inserted into a human body part and located as close to the surgical site as possible, so that after the medical device enters the bottom tube 200 through the card cover 100, the medical device enters the surgical site of the human body along the pipe 220 to perform surgery on the human body.

[0133] According to an embodiment of the present disclosure, when installing the multi-channel puncture card, the card cover 100 is placed on the bottom tube 200, and the first positioning hole 111 and the second positioning hole 203 are connected using the spring-type latch mechanism 210 to fix the card cover 100 on the bottom tube 200.

[0134] According to an embodiment of the present disclosure, after the operation is completed, the second positioning hole 203 and the first positioning hole 111 can be disengaged through the spring-loaded latch mechanism 210 to separate the card cover 100 from the bottom tube 200, thereby facilitating the cleaning of the multi-channel puncture card and the replacement of damaged parts.

[0135] like Figure 3As shown, the spring latch mechanism 210 includes a mounting frame 211 , a fixing screw 212 , a compression spring 213 and a positioning pin 214 .

[0136] The mounting frame 211 is mounted on the outer wall of the main body 201, wherein the mounting frame 211 is provided with a mounting groove, and the top and bottom surfaces of the mounting groove are provided with through holes;

[0137] A fixing screw 212 is installed at the bottom of the mounting slot;

[0138] A compression spring 213, one end of which is sleeved on the fixing screw 212;

[0139] The positioning pin 214 is installed in the mounting groove and one end of the positioning pin 214 can slide in the through hole on the top surface of the mounting groove, so that the positioning pin 214 can be connected to the first positioning hole 111 through the second positioning hole 203. A baffle is provided on the positioning pin 214 in the mounting groove, and the positioning pin 214 between the baffle and the compression spring 213 is inserted into the compression spring 213.

[0140] According to an embodiment of the present disclosure, the mounting frame 211 may be T-shaped, and both sides of the mounting frame 211 may be fixed to the outer wall of the base tube 200 by bolts. Fixing screws 212 are secured to the bottom of the mounting slot through through-holes in the bottom surface of the mounting slot. A compression spring 213 is sleeved at one end over the fixing screws 212 and at the other end over a positioning pin 214. One end of the positioning pin 214 extends through a through-hole in the top surface of the mounting slot.
