[0002] The single-hole multi-channel puncture devices currently available on the market, the single hole refers to the incision protection cover part on the lower side. During surgery, only one incision is needed, and then the incision protection cover covers the wound, while the multi-channel refers to the channel above the connection cover. The multi-channel part can generally be divided into three types: 5mm, 10mm, and 12mm. Different types of channels will be used in conjunction with different surgical situations.

[0003] Document CN215306527U discloses a single-hole multi-channel puncture device, wherein the single-hole multi-channel puncture device comprises: an incision protection sleeve; a connection cover connected to the incision protection sleeve, and the connection cover is provided with a plurality of through holes; a plurality of channel pieces, and at least two channel pieces have different channel opening sizes; and a plurality of plugging pieces; any of the through holes can be adapted to be connected to a channel piece, or can be blocked by a plugging piece. The technical solution of the utility model allows doctors to assemble or replace channel pieces with different channel opening sizes on site.

[0004] When the single-hole multi-channel puncture device in the prior art is in use, the through holes are usually fixedly mounted on the connecting cover, and a plurality of through holes are usually provided. In actual use, only a portion of the through holes are used, and the other unused through holes are sealed and blocked using a blocking structure. However, since the through holes are usually fixed on the connecting cover and the overall volume of the puncture device is not large, the spacing between the through holes is small, which affects the normal use of medical staff. At the same time, the non-detachable manner of the through holes also increases the use cost of the single-hole multi-channel puncture device and reduces the use adaptability of the single-hole multi-channel puncture device.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. When medical personnel need to install a through hole, they can align the L-shaped block and the L-shaped block and insert them into the first pressing groove and the second pressing groove respectively, and then rotate the through hole clockwise so that the L-shaped block and the L-shaped block slide along the bottom surfaces of the first oblique bottom protrusion and the second oblique bottom protrusion respectively. Under the inclined bottom surface setting of the first oblique bottom protrusion and the second oblique bottom protrusion, the through hole can be driven to be pressed on the top surface of the connecting cover through the first pressing groove and the second pressing groove until the triangular clamping groove moves to the position of the trapezoidal clamping block, and the through hole can be clamped and fixed on the connecting cover under the clamping action between the trapezoidal clamping block and the triangular clamping groove.

One action completes multiple effects, realizes the detachable through hole, and also improves the installation convenience of the through hole.

[0020] 2. When the through hole needs to be disassembled, the L-shaped block can be lifted by the concave and convex friction surface to separate the trapezoidal block from the triangular slot, and then the through hole can be removed from the connection cover by rotating the through hole counterclockwise. The disassembly and assembly is convenient and quick, and the user experience is good.

[0021] 3. When the through hole is not installed on the connecting cover, the main body of the blocking plate will seal the lower opening of the hole. When the medical staff aligns the L-shaped block and the L-shaped block and inserts them into the first clamping groove and the second clamping groove respectively, the lower end of the L-shaped block will be inserted between the raised plates at the same time. When the medical staff rotates the through hole clockwise, the L-shaped block will drive the T-shaped plate to slide along the T-shaped groove as a whole through the raised plate. Under the meshing action between the gear and the tooth block, the T-shaped plate will drive the gear to rotate, and the gear will connect the shaft and The outer wall protrusion drives the sealing plate body to rotate as a whole, thereby losing the sealing effect on the hole and realizing the connection between the through hole and the connecting cover. Similarly, when the through hole is rotated counterclockwise and removed from the connecting cover, the sealing plate body is driven to seal the hole. The structure is cleverly set. When rotating the through hole, medical staff can achieve multiple effects at the same time. While ensuring that the through hole is automatically sealed when the through hole is not installed, it also realizes the automatic opening of the hole when the through hole is installed, ensuring the sealing of the hole when it is not connected, which is convenient for use.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] In order to solve the technical problem of how to realize the disassembly and assembly of the through hole 4 on the connection cover 1 according to different usage conditions, such as Figure 1-Figure 5 , Fig.11 and Fig.12 As shown, the following preferred technical solutions are provided:

[0037] A single-hole multi-channel puncture device comprises a connecting cover 1 connected to an incision protection sleeve 3 at the bottom of the connecting cover 1, and sealable pipes 2 are respectively installed on the outer walls at both ends of the outer periphery of the connecting cover 1, and a plurality of through holes 4 are evenly distributed on the top surface of the connecting cover 1, and a plurality of card blocks 5 are evenly distributed and plugged and installed on the top surface of the connecting cover 1, and the card blocks 5 are respectively correspondingly arranged at the outer ends of the through holes 4, and the plugging components 6 are respectively installed on the top surface of the inner cavity of the connecting cover 1, and the plugging components 6 are respectively correspondingly arranged below the through holes 4.

[0039] A chamber 11 is provided in the inner cavity of the connecting cover 1, and a plurality of holes 12 are evenly distributed on the top surface of the connecting cover 1, and the through holes 4 are respectively installed at the upper end openings of the holes 12, and a plurality of first pressing grooves 13 and second pressing grooves 16 are provided on the top surface of the connecting cover 1, and the first pressing grooves 13 and the second pressing grooves 16 are respectively correspondingly arranged at the two ends of the upper end opening of the holes 12, a plurality of square sliding holes 14 are provided on the top surface of the connecting cover 1, and the square sliding holes 14 are respectively arranged at the outer end of one side of the first pressing groove 13, and the square sliding holes 14 are connected with the first pressing groove 13, a plurality of circular sliding grooves 15 are also provided on the top surface of the connecting cover 1, and the square sliding holes 14 are respectively arranged at the outer ends of the square sliding holes 14, a plurality of inner fan-shaped grooves 17 are provided in the inner cavity of the connecting cover 1, and the inner fan-shaped grooves 17 are respectively connected at the lower ends of the second pressing grooves 16, and the upper ends of the first pressing grooves 13 A first oblique bottom protrusion 131 is provided at the outer end of one side, and a second oblique bottom protrusion 161 is provided at the outer end of the other side of the upper end of the second clamping groove 16. Through the setting of the first oblique bottom protrusion 131 and the second oblique bottom protrusion 161, the top openings of the first clamping groove 13 and the second clamping groove 16 are both L-shaped, and a T-shaped slide groove 171 is provided on the bottom surface of the inner end of the inner cavity of the inner fan-shaped groove 17, and a connecting groove 172 is provided on the inner wall of the middle part of the inner end of the inner cavity of the inner fan-shaped groove 17, and a T-shaped rotating groove 173 is provided at the middle part of the top surface of the connecting rotating groove 172. Through the inclined setting of the bottom surfaces of the first oblique bottom protrusion 131 and the second oblique bottom protrusion 161, when the L-shaped block 42 and the L-shaped block 43 are respectively rotated into the first clamping groove 13 and the second clamping groove 16, the through-hole pipe body 41 can be pressed on the top surface of the connecting cover 1, thereby ensuring the sealing effect between the through-hole pipe body 41 and the connecting cover 1.

[0040] The through hole 4 includes a through hole tube body 41 and a clamping L-shaped block 42 fixedly installed at the outer end of the bottom periphery of the through hole tube body 41, and a triangular clamping groove 44 is provided on the top surface of the clamping L-shaped block 42, and an L-shaped block 43 is fixedly installed at the inner end of the bottom periphery of the through hole 4.

[0041] The card block 5 includes an L-shaped block 51 and a trapezoidal card block 52 fixedly installed on the bottom surface of the lower end of the L-shaped block 51, and a telescopic slide column 53 is fixedly installed on the middle bottom surface of the L-shaped block 51, and the telescopic slide column 53 is elastically slidably inserted in the circular slide groove 15 through a return spring 54. By setting the return spring 54, the automatic card connection effect and automatic return effect of the card block 5 can be achieved, and the trapezoidal card block 52 is slidably set in the square slide hole 14, and the lower end of the trapezoidal card block 52 is protruding from the lower end opening of the square slide hole 14. Concave and convex friction surfaces 511 are respectively provided on the outer walls on both sides of the L-shaped block 51, which are used to facilitate medical personnel to lift the L-shaped block 51 upwards and achieve an anti-slip effect.

[0042] Specifically, when the medical staff needs to install the through hole 4, the clamping L-shaped block 42 and the L-shaped block 43 can be aligned and inserted into the first clamping groove 13 and the second clamping groove 16 respectively, and then the through hole 4 can be rotated clockwise, so that the clamping L-shaped block 42 and the L-shaped block 43 slide along the bottom surface of the first inclined bottom protrusion 131 and the second inclined bottom protrusion 161 respectively. Under the inclined bottom surface setting of the first inclined bottom protrusion 131 and the second inclined bottom protrusion 161, the through hole 4 can be driven by the first clamping groove 13 and the second clamping groove 16. The hole 4 is pressed against the top surface of the connecting cover 1 until the triangular slot 44 moves to the position of the trapezoidal block 52, and the through hole 4 can be clamped and fixed on the connecting cover 1 under the clamping action between the trapezoidal block 52 and the triangular slot 44. The structure is cleverly arranged. When the medical staff rotates the through hole 4, the through hole 4 can be sealed and pressed against the connecting cover 1 and the through hole 4 can be clamped and fixed on the connecting cover 1 at the same time. One action can achieve multiple effects, and the through hole 4 can be disassembled while improving the installation convenience of the through hole 4.

[0043] Furthermore, when the through hole 4 needs to be removed, the L-shaped block 51 can be lifted up through the concave-convex friction surface 511 to separate the trapezoidal block 52 from the triangular slot 44, and then the through hole 4 is rotated counterclockwise to remove the through hole 4 from the connecting cover 1. The disassembly and assembly is convenient and quick, and the user experience is good.

[0044] In order to solve the technical problem of how to automatically open the hole 12 when installing the through hole 4, and automatically close the hole 12 after removing the through hole 4, so as to prevent leakage when the hole 12 is not connected, as shown in FIG. Figure 1-Figure 12 As shown, the following preferred technical solutions are provided:

[0045] The plugging assembly 6 includes a plurality of drive plates 61 and a plurality of plugging circular plates 62 movably mounted on the top surface of the inner cavity of the chamber 11, and the plugging circular plates 62 are respectively sealed and correspondingly arranged at the lower end openings of the holes 12, and the drive plates 61 are respectively slidably arranged on the bottom surface of the inner cavity of the inner fan-shaped groove 17, and the drive plate 61 includes a T-shaped plate 611 and a plurality of tooth blocks 612 uniformly fixedly mounted on the outer wall of the inner end of the T-shaped plate 611, and a T-shaped slider 614 is fixedly mounted on the bottom surface of the T-shaped plate 611, and the T-shaped slider 614 is slidably arranged in the T-shaped slide groove 171, and raised plates 613 are respectively fixedly mounted on both sides of the outer end of the top surface of the T-shaped plate 611, and the overall height of the L-shaped block 43 is set to be greater than the depth of the second clamping groove 16, thereby ensuring that when the L-shaped block 43 is inserted into the second clamping groove 16, the L The lower end of the L-shaped block 43 will be inserted between the raised plates 613 at the same time. At the same time, when the L-shaped block 43 is directly inserted into the second clamping groove 16, the top surface of the lower end of the L-shaped block 43 is set 1-2mm lower than the bottom surface of the second inclined bottom protrusion 161. The setting relationship between the clamping L-shaped block 42 and the first clamping groove 13 is the same as above. The blocking circular plate 62 includes a blocking plate main body 621 and an outer wall protrusion 622 fixedly installed on the outer peripheral outer wall of the blocking plate main body 621, and a connecting shaft 623 is fixedly installed on the top surface of the outer wall protrusion 622, and a gear 624 is fixedly installed on the upper end of the connecting shaft 623, and a T-shaped rotating block 625 is fixedly installed at the middle of the top surface of the gear 624, and the T-shaped rotating block 625 is movably installed in the T-shaped rotating groove 173, and the gear 624 is meshingly connected with the tooth block 612.

[0046] Specifically, when the through hole 4 is not installed on the connecting cover 1, the blocking plate body 621 will seal and block the lower end opening of the hole 12. When the medical staff aligns and inserts the L-shaped block 42 and the L-shaped block 43 into the first clamping groove 13 and the second clamping groove 16 respectively, the lower end of the L-shaped block 43 will be inserted between the raised plates 613 at the same time. When the medical staff rotates the through hole 4 clockwise, the L-shaped block 43 will drive the T-shaped plate 611 to slide along the T-shaped slide groove 171 as a whole through the raised plate 613. Under the meshing action between the gear 624 and the tooth block 612, the T-shaped plate 611 will drive the gear 624 to rotate, and the gear 62 4 will drive the blocking plate body 621 to rotate as a whole through the connecting shaft 623 and the outer wall protrusion 622, thereby losing the blocking effect on the hole 12, and realizing the connection between the through hole 4 and the connecting cover 1. Similarly, when the through hole 4 is removed from the connecting cover 1 by rotating counterclockwise, the blocking plate body 621 is driven to block the hole 12. The structure is cleverly set. When the medical staff rotates the through hole 4, multiple effects can be achieved at the same time. While ensuring that the hole 12 is automatically blocked when the through hole 4 is not installed, the hole 12 is automatically opened when the through hole 4 is installed, ensuring the sealing of the hole 12 when it is not connected, which is convenient for use.
