Description

Technical Field

[0001] This application relates to the technical field of medical devices, and specifically, to a suture staple device for an endoscope with controllable depth. Background Art

[0002] With the development of medical science and technology, minimally invasive surgery with the aid of an endoscope has gradually become the mainstream for gastrointestinal diseases. As an inspection instrument, the endoscope itself cannot perform surgical functions. Usually, the operator needs to use a minimally invasive medical device to pass through the forceps channel hole of the endoscope, so as to reach the target lesion position following the endoscope's lens. Then, the operator uses the minimally invasive medical device to perform corresponding surgical operations on the target lesion position.

[0003] The suture staple device for an endoscope is a common minimally invasive medical device, which generally includes: a handle, a handle cap, a cable, an elastic tube, and a suture staple assembly. The handle cap is rotatably connected to the handle. The elastic tube is connected to the handle cap. The cable is located inside the elastic tube. The free end of the cable is provided with the suture staple assembly. By controlling the rotation of the cable, the suture staple assembly can be driven to rotate, so as to screw the spring section of the suture staple assembly into the human body component. In the prior art, the cable is usually driven to rotate by sliding a slip ring on the handle. During the process of the operator pushing the slip ring, it is difficult to determine the depth of the suture staple assembly implanted into the tissue, resulting in the normal human tissue being pricked and bleeding, which is not conducive to accurate and effective surgical operations, and there is a probability of medical accidents, and the user experience is poor.

[0044] See Figures 1 to 5As shown in the figure, an endoscope stapling device with controllable depth provided by an embodiment of the present application includes: a handle 1, a handle cap 7, an elastic tube 2, a cable 4, and a slip ring 5. The handle cap 7 is rotatably connected to one end of the handle 1. A rotary drive assembly 73 is provided on the handle cap 7. The rotary drive assembly 73 is in transmission connection with the handle 1. The rotary drive assembly 73 includes an indicating block 732. One end of the elastic tube 2 is connected to the handle 1. The cable 4 is slidably disposed within the elastic tube 2. One end of the cable 4 is connected to a stapling component 300. The slip ring 5 is slidably disposed on the handle 1. The slip ring 5 is in transmission connection with the other end of the cable 4. The handle 1 and the slip ring 5 can rotate synchronously. In a state where the handle 1 and the slip ring 5 rotate around the handle cap 7, the slip ring 5 can drive the stapling component 300 to rotate through the cable 4, so that the stapling component 300 can be screwed into human tissue. The handle 1 can drive the indicating block 732 of the rotary drive assembly 73 to move along the length direction of the handle 1. The more turns the handle 1 rotates, the longer the moving distance of the indicating block 732. The moving distance of the indicating block 732 represents the depth of implantation of the stapling component 300 into the tissue. It is convenient for the surgeon to master the depth of implantation of the stapling component 300 into human tissue and assist the surgeon to complete the operation accurately and efficiently.

[0045] In some possible implementation schemes, as shown in Figure 2 the figure, the handle cap 7 has a cap cavity 75 and a guiding groove 74 communicating with the cap cavity 75. The rotary drive assembly 73 includes a rotary linkage 731. The rotary linkage 731 is rotatably disposed in the cap cavity 75. The rotary linkage 731 has an external thread. The indicating block 732 is slidably disposed in the guiding groove 74, and the indicating block 732 is threadedly connected to the rotary linkage 731. One end of the handle 1 extends into the cap cavity 75 and is in transmission cooperation with the rotary linkage 731. The handle 1 and the rotary linkage 731 can rotate synchronously. In an embodiment of the present application, the rotary drive assembly 73 adopts a nut-screw matching structure. By driving the rotary linkage 731 to rotate through the handle 1, the indicating block 732 can be translated along the length direction of the rotary linkage 731.

[0046] As shown in Figure 2 and Figure 3As shown, the inner wall of the handle cap 7 is provided with guide ribs 70 which extend along the circumferential direction of the handle cap 7. One end of the handle 1 is provided with an annular groove 122 which extends along the circumferential direction of the handle 1. In the state where the handle cap 7 is sleeved on the handle 1, the guide ribs 70 are embedded in the annular groove 122. The guide ribs 70 are not a closed ring. Multiple guide ribs 70 can be provided on the inner wall of the handle cap 7, and the guide ribs 70 are sequentially arranged along the circumferential direction of the handle cap 7. There is a disconnection area between adjacent guide ribs 70, which is beneficial to inserting and installing the end of the handle 1 into the handle cap. The handle cap 7 is made of plastic and has a certain deformation ability. Since the guide ribs 70 are not a closed ring, under sufficient external force, the end of the handle 1 can be inserted into the inside of the handle cap 7 by slight deformation, so that the guide ribs 70 are snapped into the annular groove 122.

[0047] In some possible implementation schemes, the handle cap 7 has a support groove 76 which communicates with the cap cavity 75. The support groove 76 is located on the side of the cap cavity 75 away from the handle 1. The rotary linkage member 731 includes a screw portion 7311 and a rotary shaft 7312 and a linkage shaft 7313 respectively arranged at both ends of the screw. The screw portion 7311 is located in the cap cavity 75. The indicating block 732 is threadedly connected to the screw. The rotary shaft 7312 is connected to the support groove 76. The linkage shaft 7313 is in transmission cooperation with the handle 1, so that both ends of the rotary shaft 7312 can be effectively supported.

[0048] In some possible implementation schemes, a limit slot 121 is provided at the end of the handle 1. The linkage shaft 7313 is inserted into the limit slot 121, and the linkage shaft 7313 rotates synchronously with the handle 1. The limit slot 121 is not a circular hole, and the cross section of the linkage shaft 7313 is not circular either. In the state where the linkage shaft 7313 is inserted into the limit slot 121, the linkage shaft 7313 cannot rotate relative to the handle 1, but rotates synchronously with the handle 1.

[0049] In some possible implementation schemes, the handle 1 is provided with an outward expanding inclined surface at the mouth end of the limit slot 121 and / or the linkage shaft 7313 is provided with a narrowing inclined surface at the end away from the rotary shaft 7312, so that the linkage shaft 7313 can be smoothly inserted into the limit slot 121 of the handle 1.

[0050] In some possible implementation schemes, refer to Figure 2 and Figure 4As shown, the indicating block 732 has a main body section 7321 and an indicating section 7322. The thickness of the main body section 7321 is greater than that of the indicating section 7322. A through threaded groove 7323 is provided on the thickness end surface of the main body section 7321. The main body section 7321 is located within the cap cavity 75 and is threadedly connected to the rotary linkage 731 through the threaded groove 7323. One end of the indicating section 7322 is connected to the main body section 7321, and the other end of the indicating section 7322 extends to the guiding groove 74.

[0051] The main body section 7321 is large in volume, facilitating the setting of the threaded groove 7323. The indicating section 7322 can be of a gradually narrowing structure, which can reduce the volume, avoid frictional interference with the guiding groove 74, and can move smoothly along the guiding groove 74.

[0052] In some possible implementation manners, the cap cavity 75 has two opposite limiting inner walls. The two limiting inner walls limit the two sides of the main body section 7321 in the thickness direction, restricting the main body section 7321 from rotating around the rotary linkage 731, such that the main body section 7321 can only move under the drive of the screw part 7311 and will not rotate along with the screw part 7311.

[0053] In some possible implementation manners, a scale marking part (not shown) is provided on the handle cap 7. The scale marking part is arranged along the length direction of the guiding groove 74. The setting of the scale marking part can facilitate the operator to quickly know the implantation depth of the staple assembly 300 and assist the operator in performing accurate and efficient surgical operations.

[0054] In some possible implementation manners, the depth - controllable endoscopic staple device includes a cable 4 and a slip ring 5. The slip ring 5 is slidably arranged on the handle 1. The rotary linkage 731 has a through groove. The cable 4 is arranged through the through groove, and the cable 4 is connected to the slip ring 5. During the process of the slip ring 5 sliding along the handle 1, the cable 4 can slide along the through groove of the rotary linkage 731. During the process of the handle 1 and the slip ring 5 rotating synchronously, the handle 1 drives the rotary linkage 731 to rotate, and the slip ring 5 will drive the cable 4 to rotate synchronously with the handle.
