Endoscope clamping type arc-shaped needle puncture device

Abstract

The utility model provides an endoscope clamping type arc-shaped needle puncture device, which is characterized in that a clamping control piece controls a matching space of a locking piece to be tightened, so that the locking piece is fixedly connected with an arc-shaped suture needle; the rotating control piece controls the connecting piece to rotate relative to the mounting frame from the initial position, and the connecting piece drives the arc-shaped suture needle to rotate relative to the shell so that the arc-shaped suture needle can penetrate through the mucosal tissue of the human body. After the connecting piece moves to the final position, reverse operation is carried out to enable the connecting piece to return to the initial position, and the operation is repeated for multiple times so that the arc-shaped suture needle can repeatedly rotate by 360 degrees to suture the mucosal tissue of the human body; due to the fact that the locking piece can be fixed to any position of the arc-shaped suture needle, the arc-shaped suture needle can be driven to rotate by any angle, the precision requirement for matching between the locking piece and the arc-shaped suture needle is lowered, and when the arc-shaped suture needle punctures a hard human mucosa tissue and is blocked or the rotating stroke is not enough, the arc-shaped suture needle can be driven to rotate by any angle. The locking piece can timely adjust the fixed position point so as to provide enough puncture force and rotation stroke for the arc-shaped suture needle.

The following discussion provides multiple embodiments of this utility model. Although each embodiment represents a single combination of the applications, different embodiments of this utility model can be substituted or combined; therefore, this utility model can also be considered to include all possible combinations of the same and / or different embodiments described. Thus, if one embodiment includes A, B, and C, and another embodiment includes a combination of B and D, then this utility model should also be considered to include embodiments containing one or more other all other possible combinations of A, B, C, and D, even if such embodiments are not explicitly described in the following text. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0051] like Figures 1 to 19 As shown, the endoscopic clamping arc needle puncture device provided by this utility model includes: a housing 10, an arc suture needle 20, a mounting bracket 30, a connector 40, a locking component 50, a clamping control component 60, and a rotation control component 70.

[0052] The housing 10 includes a suture groove 11 and an arc-shaped suture hole 12, the suture groove 11 being configured to accommodate human mucosal tissue.

[0053] The arc-shaped suture needle 20 is rotatably disposed within the arc-shaped suture hole 12.

[0054] Mounting bracket 30 is fixed inside housing 10.

[0055] One end of the connector 40 is rotatably connected to the mounting bracket 30.

[0056] The locking member 50 is connected to the other end of the connecting member 40. The locking member 50 is provided with a mating space, which mates with the arc-shaped suture needle 20.

[0057] The clamping control 60 is connected to the locking member 50, and the clamping control 60 is configured to control the tightening of the mating space of the locking member 50 so as to fix the locking member 50 to the arc-shaped suture needle 20.

[0058] The rotation control element 70 is connected to the connector 40 and is configured to control the rotation of the connector 40 relative to the mounting bracket 30. Specifically, the rotation control element 70 can be a flexible shaft. On the one hand, the flexible shaft can be bent and twisted to adapt to different working conditions during the movement of the connector 40. On the other hand, the flexible shaft is usually made of high-strength materials and has wear-resistant, corrosion-resistant, and fatigue-resistant properties, thereby improving the service life and reliability of the flexible shaft. Furthermore, the installation of the flexible shaft is relatively simple and does not require complex mechanical structures or fixing devices. The operator can rotate the flexible shaft directly by hand or drive it to rotate via an external motor.

[0059] The endoscope clamping type arc-shaped needle puncture device provided by the utility model, the operator controls the cooperation space of the locking piece 50 to be tightened through the clamping control piece 60, so that the locking piece 50 is fixedly connected with the arc-shaped suture needle 20, then the operator controls the connecting piece 40 to rotate relative to the mounting frame 30 through the rotating control piece 70, the connecting piece 40 drives the arc-shaped suture needle 20 to rotate relative to the shell 10 along the first direction, so that the arc-shaped suture needle 20 rotates relative to the shell 10, so that the arc-shaped suture needle 20 penetrates the human mucosa tissue. When the connecting piece 40 moves to the terminal position, the operator controls the cooperation space of the locking piece 50 to be widened through the clamping control piece 60, so that the locking piece 50 is separated from the arc-shaped suture needle 20, the operator controls the connecting piece 40 to rotate relative to the mounting frame 30 through the rotating control piece 70, the connecting piece 40 rotates relative to the shell 10 along the second direction, so that the connecting piece 40 returns to the initial position, and the above operation is repeated at least once, so that the arc-shaped suture needle 20 rotates one circle relative to the shell 10, so that the arc-shaped suture needle 20 penetrates the human mucosa tissue, and the above operation is repeated, so that the arc-shaped suture needle 20 rotates multiple circles relative to the shell 10, so that the arc-shaped suture needle 20 is sutured to the human mucosa tissue, and in the above process, since the locking piece can be fixed at any position of the arc-shaped suture needle, the locking piece can drive the arc-shaped suture needle to rotate by any angle, and the locking piece drives the arc-shaped suture needle to rotate at least twice, so that the arc-shaped suture needle rotates by 360 degrees. The above structure is reasonable in design, compact in structure and convenient to use, the cooperation between the connecting piece 40, the locking piece 50, the clamping control piece 60 and the rotating control piece 70 drives the arc-shaped suture needle 20 to repeatedly rotate by 360 degrees relative to the shell 10, so that the human mucosa tissue is sutured, and the operation efficiency is improved.

[0060] In addition, since the locking piece 50 can be fixed at any position of the arc-shaped suture needle 20, the arc-shaped suture needle 20 can be driven to rotate by any angle, the precision requirement of cooperation between the locking piece 50 and the arc-shaped suture needle 20 is greatly reduced, the situation that the locking piece 50 and the arc-shaped suture needle 20 are not matched in precision and the device fails is avoided, when the arc-shaped suture needle 20 is blocked by the hard human mucosa tissue or the rotation stroke is not enough, the locking piece 50 can timely adjust the fixed position point to provide sufficient puncture strength and rotation stroke of the arc-shaped suture needle 20, so that the human mucosa tissue is sutured, and the operation efficiency is improved.

[0061] As shown in Figure 2 , Figure 3 , Figure 8 and Figure 9 indicate that, in an embodiment of the utility model, the shell 10 comprises a base shell 13 and a base 14.

[0062] The locking member 50 and the mounting frame 30 are arranged in the base shell 13, the base 14 is connected with the base shell 13, and the suture groove 11 is arranged on the base 14.

[0063] The base 14 is provided with a first arc-shaped groove 141.

[0064] As shown in Figure 7 and Figure 8 , the mounting frame 30 is arranged with an avoiding hole 36 and a second arc-shaped groove 34, and the mounting frame 30 is arranged on the base 14, and the second arc-shaped groove 34 and the first arc-shaped groove 141 form the arc-shaped suture hole 12.

[0065] The avoiding hole 36 is arranged along the circumference of the arc-shaped suture hole 12, and in the direction of the rotation axis of the arc-shaped suture needle 20, the avoiding hole 36 penetrates through the mounting frame 30, and the locking member 50 extends into the arc-shaped suture hole 12 through the avoiding hole 36. The avoiding hole 36 provides a space for the locking member 50 to be opened and clamped in the arc-shaped suture needle 20.

[0066] In the assembly process of the product, the arc-shaped suture needle 20 can be first installed into the first arc-shaped groove 141, and then the mounting frame 30 is fixed on the base 14, and the second arc-shaped groove 34 corresponds to the first arc-shaped groove 141 to form the arc-shaped suture hole 12. The above structure facilitates the disassembly and assembly of the arc-shaped suture needle 20, thereby facilitating the replacement and assembly of the arc-shaped suture needle 20.

[0067] As shown in Figures 5 to 7 , in an embodiment of the utility model, the mounting frame 30 is provided with a groove plate 35, in the direction of the rotation axis of the arc-shaped suture needle 20, the groove plate 35 extends away from the mounting frame 30, the groove wall of the second arc-shaped groove 34 is connected with one side of the groove plate 35, and the groove plate 35 and the groove wall of the suture groove 11 enclose the opening 15 of the arc-shaped suture hole 12.

[0068] The opening 15 formed by the groove plate 35 and the groove wall of the suture groove 11 is open, the edge of which is shallow in the depth of the arc-shaped needle hole and faces the mucous membrane tissue of the human body, so that when the arc-shaped suture needle 20 rotates in the arc-shaped needle hole, the suture connected with the arc-shaped suture needle 20 smoothly comes out of the arc-shaped needle hole, thereby reducing the probability of the suture winding in the arc-shaped needle hole, improving the use comfort and reliability of the product, and ensuring the smooth suture of the suture device to the mucous membrane tissue of the human body.

[0069] As shown in Figure 3 , in an embodiment of the utility model, the clamping control member 60 includes a control cord 61 and an outer tube 62.

[0070] One end of the outer tube 62 is fixedly connected with the connecting member 40, and the other end of the outer tube 62 extends out of the shell 10.

[0071] One end of the control cord 61 is inserted into the outer tube 62 and connected with the locking member 50, and the other end of the control cord 61 extends out of the outer tube 62.

[0072] As shown in the drawings, Figures 10 to 12 In one embodiment of the present application, the mounting frame 30 comprises a fixed part 31 and a mounting part 32.

[0073] The fixed part 31 is connected with the shell 10.

[0074] The connecting member 40 is mounted on the mounting part 32, and the mounting part 32 is provided with a relief space 33 which is in communication with the suture groove 11.

[0075] The provision of the relief space 33 reduces the interference between the mounting frame 30 and the human mucosal tissue, i.e. the human mucosal tissue can enter the relief space 33, so that the suture groove 11 can accommodate more human mucosal tissue, and thus the arc-shaped suture needle 20 can effectively suture the human mucosal tissue, ensuring the suture effect on the human mucosal tissue.

[0076] The following will specifically describe several embodiments of the endoscope clamping type arc-shaped needle puncture device.

[0077] Embodiment one

[0078] As shown in the drawings, Figure 2 and Figure 3 The endoscope clamping type arc-shaped needle puncture device provided by the present application comprises a shell 10, an arc-shaped suture needle 20, a mounting frame 30, a connecting member 40, a locking member 50, a clamping control member 60 and a rotating control member 70.

[0079] The locking member 50 comprises a first clamping arm 51 and a second clamping arm 52.

[0080] A matching space is provided between the first clamping arm 51 and the second clamping arm 52, and the clamping control member 60 is configured to control the relative movement of the first clamping arm 51 and the second clamping arm 52 to tighten the matching space, so as to clamp the arc-shaped suture needle 20.

[0081] The first clamping arm 51 and the second clamping arm 52 are rotatably connected with the connecting member 40 through a connecting shaft 53, and the clamping control member 60 is connected with the first clamping arm 51 and the second clamping arm 52 respectively.

[0082] The clamping control member 60 controls the movement of the first clamping arm 51 and the second clamping arm 52 relative to the connecting member 40 respectively, so that the matching space between the first clamping arm 51 and the second clamping arm 52 is tightened to clamp the arc-shaped suture needle 20.

[0083] The operation process of the endoscope clamping type arc-shaped needle puncture device is as follows:

[0084] The operator controls the movement of the first clamping arm 51 and the second clamping arm 52 relative to the connector 40 through the clamping control 60, so that the first clamping arm 51 and the second clamping arm 52 clamp the arc-shaped suture needle 20. Then, the operator controls the connector 40 to rotate relative to the mounting bracket 30 through the rotation control 70. The connector 40 drives the arc-shaped suture needle 20 to rotate relative to the housing 10 in the first direction, so that the arc-shaped suture needle 20 rotates relative to the housing 10, so that the arc-shaped suture needle 20 passes through the human mucosal tissue. After the connector 40 moves to the end position, the operator controls the first clamping arm 51 and the second clamping arm 52 to move relative to the connector 40 through the clamping control 60, so that the first clamping arm 51 and the second clamping arm 52 are separated from the arc-shaped suture needle 20. The operator controls the connector 40 to rotate relative to the mounting bracket 30 through the rotation control 70. The connector 40 rotates relative to the housing 10 in the second direction, so that the connector 40 returns to the initial position. The above operation is repeated at least once, so that the arc-shaped suture needle 20 rotates one revolution relative to the housing 10 (that is, the arc-shaped suture needle 20 rotates 360° relative to the housing 10), so that the arc-shaped suture needle 20 passes through the human mucosal tissue. This process is repeated so that the arc-shaped suture needle 20 rotates one revolution relative to the housing 10 multiple times to complete the suturing of the human mucosal tissue. It should be noted that the locking member 50 drives the arc-shaped suture needle 20 to rotate multiple times relative to the housing 10, ultimately achieving a 360° rotation of the arc-shaped suture needle 20. The angle of rotation of the arc-shaped suture needle 20 each time is related to the position of the arc-shaped suture needle 20 held by the first clamping arm 51 and the second clamping arm 52.

[0085] The locking component 50 has a simple and compact structure, does not involve complex micro-precision parts, and has fewer structural components. On the one hand, it reduces the complexity of the design, thereby reducing the manufacturing process and reducing the interfaces and fits between parts, thus simplifying the structure of the entire system.

[0086] Furthermore, the aforementioned locking member 50 is a double-arm clamp. On one hand, the first clamping arm 51 and the second clamping arm 52 can move simultaneously and clamp the arc-shaped suture needle 20, reducing the individual movement distance of the first clamping arm 51 and the vibration generated during the movement process, thereby ensuring stable clamping of the arc-shaped suture needle 20 by the locking member 50. On the other hand, the simultaneous clamping of the arc-shaped suture needle 20 by the first clamping arm 51 and the second clamping arm 52 ensures that the arc-shaped suture needle 20 is subjected to uniform force, reducing the risk of deformation of the arc-shaped suture needle 20.

[0087] like Figure 8 and Figure 9 As shown, in one embodiment of the present invention, the arc-shaped suture hole 12 includes a guide portion 121 and a clearance portion 122.

[0088] The position of the avoidance part 122 corresponds to the position of the locking part 50.

[0089] The length of the guiding portion 121 is greater than that of the avoiding portion 122 in the circumferential direction of the arc-shaped suture hole 12, and the two ends of the guiding portion 121 are respectively staggered with the two ends of the avoiding portion 122.

[0090] The guiding portion 121 is used for accommodating the arc-shaped suture needle 20, and the avoiding portion 122 is used for accommodating part of the locking piece 50.

[0091] As shown in the drawings, in an embodiment of the present application, the depth of the avoiding portion 122 is greater than that of the guiding portion 121 in the direction of the rotation axis of the arc-shaped suture needle 20. Figure 9 The above structure increases the length of the second clamping arm 52 extending into the avoiding portion 122, thereby increasing the contact area of the avoiding portion 122 with the arc-shaped suture needle 20, increasing the contact area of the arc-shaped suture needle 20 with the second clamping arm 52, and further ensuring the effective clamping of the arc-shaped suture needle 20 by the locking piece 50, so as to effectively suture the mucous membrane tissue of the human body by the arc-shaped suture needle 20.

[0092] Embodiment two

[0093] As shown in the drawings, embodiment two and embodiment one have basically the same structure principle, and the difference between embodiment two and embodiment one is that the first clamping arm 51 is fixedly connected with the connecting piece 40, and the connecting piece 40 is provided with a guiding structure 41 extending along the length direction of the connecting piece 40.

[0094] Figure 13 and Figure 14 The second clamping arm 52 comprises a clamping portion 521 and a cooperating structure 522, and the cooperating structure 522 cooperates with the guiding structure 41.

[0095] The locking piece 50 further comprises a movement control piece 54.

[0096] One end of the movement control piece 54 is connected with the second clamping arm 52, and the other end of the movement control piece 54 is connected with a clamping control piece 60.

[0097] The clamping control piece 60 controls the movement of the movement control piece 54, so that the movement control piece 54 drives the second clamping arm 52 to move to tighten the cooperation space between the first clamping arm 51 and the clamping portion 521, so as to clamp the arc-shaped suture needle 20.

[0098] Specifically, the movement control piece 54 is an adapter frame 541.

[0099] ​The adapter frame 541 is arranged on the first clamping arm 51 and can rotate relative to the first clamping arm 51.

[0100] One end of the adapter frame 541 is connected with the second clamping arm 52, and the other end of the adapter frame 541 is connected with the clamping control member 60.

[0101] The clamping control member 60 controls the adapter frame 541 to rotate relative to the first clamping arm 51, so that the adapter frame 541 drives the second clamping arm 52 to move, so as to tighten the cooperation space between the first clamping arm 51 and the clamping part 521, so as to clamp the arc-shaped suture needle 20.

[0102] The operation process of the endoscopic clamping arc-shaped needle puncture device is as follows:

[0103] The operator controls the adapter frame 541 to rotate relative to the first clamping arm 51 through the clamping control member 60, so that the adapter frame 541 drives the second clamping arm 52 to move relative to the connecting member 40, so that the first clamping arm 51 and the second clamping arm 52 clamp the arc-shaped suture needle 20, then the operator controls the connecting member 40 to rotate relative to the mounting frame 30 through the rotating control member 70, so that the connecting member 40 drives the arc-shaped suture needle 20 to rotate relative to the shell 10 in the first direction, so that the arc-shaped suture needle 20 rotates relative to the shell, so that the arc-shaped suture needle 20 penetrates the human mucosa tissue. After the connecting member 40 moves to the terminal position, the operator controls the adapter frame 541 to rotate relative to the first clamping arm 51 through the clamping control member 60, so that the adapter frame 541 drives the second clamping arm 52 to move relative to the connecting member 40, so that the first clamping arm 51 and the second clamping arm 52 are separated from the arc-shaped suture needle 20, and the operator controls the connecting member 40 to rotate relative to the mounting frame 30 through the rotating control member 70, so that the connecting member 40 rotates relative to the shell 10 in the second direction, so that the connecting member 40 returns to the initial position. Repeat the above operation at least once, so that the arc-shaped suture needle 20 rotates relative to the shell 10 for one revolution (i.e. the arc-shaped suture needle 20 rotates 360° relative to the shell 10), so that the arc-shaped suture needle 20 penetrates the human mucosa tissue, and the like, so that the arc-shaped suture needle 20 rotates relative to the shell 10 for multiple revolutions, so as to complete the suture of the human mucosa tissue.

[0104] The adapter frame 541 is equivalent to a lever, by adjusting the connection position of the adapter frame 541 and the first clamping arm 51, adjusting the relationship between the power arm and the resistance arm, so that a smaller force is applied to the clamping control member 60, which can become a larger force through the transmission of the adapter frame 541 and act on the second clamping arm 52, so that the second clamping arm 52 and the first clamping arm 51 can have a larger clamping force, so as to ensure that the locking member 50 effectively clamps the arc-shaped suture needle 20, so as to effectively suture the arc-shaped suture needle 20 to the human mucosa tissue, and ensure the suture effect of the human mucosa tissue.

[0105] As Figure 14As shown, in one embodiment of the present invention, the locking member 50 further includes a reset member 55.

[0106] The reset member 55 is disposed between the clamping arm and the connecting member 40, or between the first clamping arm 51 and the second clamping arm 52, or between the clamping arm and the housing 10.

[0107] The reset member 55 is configured to store force when the mating space between the first clamping arm 51 and the second clamping arm 52 is tightened.

[0108] The clamping arms include a first clamping arm 51 and a second clamping arm 52.

[0109] After the clamping control member 60 removes the force applied to the locking member 50, the reset member 55 can ensure that the state of the locking member 50 can accurately return to the initial state, which improves the reliability and stability of the system and avoids the locking member 50 failing to reset, which would prevent it from repeatedly clamping the arc-shaped suture needle 20. In other words, it ensures that the locking member 50 can repeatedly clamp the arc-shaped suture needle 20 so that the arc-shaped suture needle 20 can effectively suture the human mucosal tissue, thereby ensuring the suturing effect of the human mucosal tissue.

[0110] Example 3

[0111] like Figure 15 and Figure 16 As shown, the structural principle of Embodiment 3 is basically the same as that of Embodiment 1. The difference between Embodiment 2 and Embodiment 1 is that the guide structure 41 is a guide hole and the mating structure 522 is a guide rod, which is inserted into the guide hole.

[0112] The connector 40 is provided with a first control hole 42 that passes through it, and the guide rod is provided with a second control hole 524 that passes through it. The first control hole 42 and the second control hole 524 are connected.

[0113] The moving control component 54 is a control block 542. The control block 542 includes a connecting end and a free end that are arranged opposite to each other. The connecting end of the control block 542 passes through the first control hole 42 and the second control hole 524 and is connected to the clamping control component 60.

[0114] The control block 542 is provided with a guide slope, and the cross-sectional area of ​​the control block 542 gradually increases in the direction from the connecting end to the free end.

[0115] The operation procedure of the endoscopic clamp-type arc needle puncture device is as follows:

[0116] The operator controls the control block 542 to move within the first control hole 42 and the second control hole 524 by using the clamping control component 60, so that the overlapping area between the first control hole 42 and the second control hole 524 gradually increases, thereby causing the second clamping arm 52 to move relative to the connector 40, so that the first clamping arm 51 and the second clamping arm 52 clamp the arc-shaped suture needle 20. Then, the operator controls the connector 40 to rotate relative to the mounting bracket 30 by using the rotation control component 70. The connector 40 drives the arc-shaped suture needle 20 to rotate relative to the housing 10 in the first direction, so that the arc-shaped suture needle 20 passes through the human mucosal tissue. After the connector 40 moves to the end position, the operator controls the control block 542 to move within the first control hole 42 and the second control hole 524 through the clamping control 60. During this process, the overlapping area between the first control hole 42 and the second control hole 524 gradually decreases, causing the second clamping arm 52 to move relative to the connector 40, so that the first clamping arm 51 and the second clamping arm 52 separate from the arc-shaped suture needle 20. The operator controls the connector 40 to rotate relative to the mounting bracket 30 through the rotation control 70. The connector 40 rotates relative to the housing 10 in the second direction, so that the connector 40 returns to the initial position. The above operation is repeated at least once, so that the arc-shaped suture needle 20 rotates one revolution relative to the housing 10 (that is, the arc-shaped suture needle 20 rotates 360° relative to the housing 10), so that the arc-shaped suture needle 20 passes through the human mucosal tissue. This process is repeated so that the arc-shaped suture needle 20 rotates one revolution relative to the housing 10 multiple times to complete the suturing of the human mucosal tissue.

[0117] The locking element 50 has a simple and compact structure. On the one hand, the guide block can provide precise guidance and positioning functions, ensuring that the guide block accurately controls the movement of the second clamping arm 52, so as to ensure the effective clamping of the arc-shaped suture needle 20 by the locking element 50.

[0118] Example 4

[0119] like Figure 17 and Figure 18 As shown, the structural principle of Embodiment 4 is basically the same as that of Embodiment 1. The difference between Embodiment 2 and Embodiment 1 is that the first clamping arm 51 is fixedly connected to the connecting member 40.

[0120] The second clamping arm 52 includes a clamping part 521 and a connecting part 523. One end of the connecting part 523 is connected to the clamping part 521, and the other end of the connecting part 523 is connected to the clamping control member 60. The connecting part 523 and the connecting member 40 are rotatably connected.

[0121] The clamping control member 60 controls the connecting part 523 to rotate relative to the connecting member 40, so that the connecting part 523 drives the clamping part 521 to move, thereby tightening the mating space between the first clamping arm 51 and the clamping part 521 to clamp the arc-shaped suture needle 20.

[0122] The operation process of the endoscope clamping type arc-shaped needle puncture device is as follows:

[0123] The operator controls the second clamping arm 52 to move relative to the connecting piece 40 through the clamping control piece 60, so that the first clamping arm 51 and the second clamping arm 52 clamp the arc-shaped suture needle 20, and then the operator controls the connecting piece 40 to rotate relative to the mounting frame 30 through the rotation control piece 70, the connecting piece 40 drives the arc-shaped suture needle 20 to rotate relative to the shell 10 in the first direction, so that the arc-shaped suture needle 20 rotates relative to the shell 10, and the arc-shaped suture needle 20 penetrates the mucosal tissue of the human body. When the connecting piece 40 moves to the end position, the operator controls the second clamping arm 52 to move relative to the connecting piece 40 through the clamping control piece 60, so that the first clamping arm 51 and the second clamping arm 52 are separated from the arc-shaped suture needle 20, and the operator controls the connecting piece 40 to rotate relative to the mounting frame 30 through the rotation control piece 70, so that the connecting piece 40 rotates relative to the shell 10 in the second direction, so that the connecting piece 40 returns to the initial position, and the above operation is repeated at least once, so that the arc-shaped suture needle 20 rotates relative to the shell 10 by 360 degrees (that is, the arc-shaped suture needle 20 rotates relative to the shell 10 by 360 degrees), so that the arc-shaped suture needle 20 penetrates the mucosal tissue of the human body, and the like, so that the arc-shaped suture needle 20 rotates relative to the shell 10 by 360 degrees many times, so as to complete the suture of the mucosal tissue of the human body.

[0124] The above-mentioned locking piece 50 is a single clamping arm clamp. On the one hand, since only the second clamping arm 52 moves, the clamping of the arc-shaped suture needle 20 by the locking piece 50 is relatively simple and fast. On the other hand, since only the second clamping arm 52 moves, the space required by the second clamping arm 52 is relatively small, so that the volume of the endoscope clamping type arc-shaped needle puncture device can be relatively small, thereby making the endoscope clamping type arc-shaped needle puncture device suitable for a limited space working environment, and increasing the use range of the product.

[0125] Example five

[0126] As shown in Figure 19 The endoscope clamping type arc-shaped needle puncture device provided by the utility model includes a shell 10, an arc-shaped suture needle 20, a mounting frame 30, a connecting piece 40, a locking piece 50, a clamping control piece 60 and a rotation control piece 70.

[0127] The locking piece 50 is a fixed sleeve ring 56, the fixed sleeve ring 56 surrounds a matching space, and the fixed sleeve ring 56 is sleeved on the arc-shaped suture needle 20.

[0128] The clamping control piece 60 controls the fixed sleeve ring 56 to become smaller so that the matching space is tightened, so that the locking piece 50 is fixedly connected with the arc-shaped suture needle 20.

[0129] The operator controls the fixed sleeve ring 56 to be smaller through the clamping control member 60, the fixed sleeve ring 56 is fastened on the arc-shaped suture needle 20, then the operator controls the connecting member 40 to rotate relative to the mounting frame 30 through the rotating control member 70, the connecting member 40 drives the arc-shaped suture needle 20 to rotate relative to the shell 10 in the first direction, so that the arc-shaped suture needle 20 rotates relative to the shell 10, so that the arc-shaped suture needle 20 penetrates the human mucosal tissue. When the connecting member 40 moves to the terminal position, the operator controls the fixed sleeve ring 56 to be larger through the clamping control member 60, so that the fixed sleeve ring 56 is separated from the arc-shaped suture needle 20, the operator controls the connecting member 40 to rotate relative to the mounting frame 30 through the rotating control member 70, the connecting member 40 rotates relative to the shell 10 in the second direction, so that the connecting member 40 returns to the initial position, and the above operation is repeated at least once, so that the arc-shaped suture needle 20 rotates relative to the shell 10 by one revolution (that is, the arc-shaped suture needle 20 rotates 360 degrees relative to the shell 10), so that the arc-shaped suture needle 20 penetrates the human mucosal tissue, and the like, so that the arc-shaped suture needle 20 rotates relative to the shell 10 by one revolution for many times, so as to complete the suture of the human mucosal tissue.

[0130] The locking member 50 is simple in structural design, does not involve complex micro-precision parts, reduces the complexity of design, thereby reducing the manufacturing process, reducing the interface and cooperation between parts, and simplifying the structure of the whole system.
