Description

Technical Field

[0001] The invention belongs to the technical field of medical instruments, and in particular relates to an endoscopic hemostasis device for thoracic surgery. Background Art

[0002] In the field of thoracic surgery, hemostasis is a key step to ensure the success of the operation and the safety of the patient. With the continuous advancement of medical technology, endoscopic technology is increasingly used in thoracic surgery, which allows the operation to be performed with smaller incisions and reduces trauma to the patient's body. The corresponding endoscopic hemostasis devices are also constantly developing, but there are still many problems that need to be solved.

[0003] Existing hemostatic devices have obvious limitations in practical applications. Most hemostatic devices are originally designed for hole-shaped bleeding points, and achieve hemostasis through mechanical clamping. However, in the complex environment of thoracic surgery, the shape of bleeding points is not a single hole. For example, in lung surgery, due to the removal of diseased tissues, separation of blood vessels and other operations, long strips of bleeding points often appear. In this case, existing hemostatic devices are powerless, and often require multiple hemostatic devices to cooperate to complete the hemostatic operation. This not only increases the complexity of the surgical operation, but also occupies more surgical space due to the use of multiple devices, making the surgical operation more difficult.

[0004] In addition, when multiple bleeding points appear during surgery, the existing hemostatic devices need to clamp and stop bleeding at each bleeding point one by one, which means that more hemostatic devices are needed, and multiple medical staff are required to operate simultaneously during the operation. This multi-person operation method not only increases the difficulty of collaboration between medical staff, but also leads to excessive concentration of medical staff in the operating area. At the same time, too many people and instruments concentrated in a limited operating area will seriously affect the surgical field of view, further increase the difficulty of surgical operations, prolong the operation time, and reduce surgical efficiency.

[0005] Based on the above problems, this application document proposes an endoscopic hemostasis device for thoracic surgery to improve the above problems. Summary of the invention

[0041] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0042] Please see attached Figure 1 to Figure 2 , Fig.10 As shown, this embodiment provides an endoscopic hemostasis device for thoracic surgery, including an overall component 10, the overall component 10 includes a grip component 11, and one side of the grip component 11 is movably sleeved with an outer tube component 12;

[0043] The hemostatic component 20 is assembled at the end of the gripping component 11 inside the outer tube component 12. The hemostatic component 20 includes a clamping component 21 arranged in the inner cavity of the gripping component 11. The end of the clamping component 21 away from the gripping component 11 is equipped with a bifurcated component 22. The end of the bifurcated component 22 facing the gripping component 11 is fixedly connected with a regulating component 23. The regulating component 23 is connected to the side of the gripping component 11 away from the outer tube component 12.

[0044] Among them, the regulating component 23 can drive the clamping component 21 to operate and drive the fork component 22 to cyclically switch among the following three forms: a merged form, a Y-shaped form, and a T-shaped form. When the fork component 22 is in the merged form, the fork component 22 can clamp and stop bleeding at a single hole-shaped bleeding point; when the fork component 22 is in the Y-shaped form, the fork component 22 can clamp and stop bleeding at multiple hole-shaped bleeding points; when the fork component 22 is in the T-shaped form, the fork component 22 can clamp and stop bleeding at long strip-shaped bleeding points.

[0045] In this embodiment, during the treatment process, after the outer tube component 12 is inserted into the patient's body, the location, number and shape of the bleeding point are checked, and then the outer tube component 12 is moved toward the direction of the holding component 11, and the clamping component 21 is extended and automatically opened, and then the regulating component 23 is moved, and the opening angle and shape of the fork component 22 are adjusted according to the shape and number of the wound, and the fork component 22 is adjusted to any one of the Y-shape and T-shape, and then the clamping component 21 is driven to clamp the wound to stop bleeding.

[0046] Secondly, please refer again to Figures 1 to 4 The holding assembly 11 includes a handle 111, a guide wire tube 112 is fixedly connected to the middle of the handle 111 near one end of the outer tube assembly 12, and a control button 113 is fixedly connected to the top of the handle 111;

[0047] The outer tube assembly 12 includes a sliding tube 121 movably sleeved on the outer ring of the guide wire tube 112, a pull handle 122 is fixedly connected to the bottom of one end of the sliding tube 121 close to the grip 111, a limiting tube 123 is fixedly connected to the bottom surface of the grip 111, the pull handle 122 is slidably connected to the inner cavity of the limiting tube 123, two groups of positioning grooves 124 are opened on the bottom surface of the pull handle 122, a positioning block 125 is slidably connected to the inner cavity of the limiting tube 123, a spring 126 is installed between the positioning block 125 and the limiting tube 123, and the positioning block 125 and the positioning groove 124 are fixedly connected to the bottom surface of the pull handle 122. 4, a pull rod 127 is fixed at the bottom of the positioning block 125 and located at the inner circle of the spring 126, and the lower end of the pull rod 127 passes through the limiting tube 123, and a camera 128 is fixedly installed in the inner cavity of the end of the sliding tube 121 away from the grip 111, wherein, when the upper end of the positioning block 125 is clamped in the positioning groove 124, the positioning block 125 can limit the sliding tube 121 and the handle 122; when the positioning block 125 and the positioning groove 124 are separated from each other, the positioning block 125 releases the limit on the sliding tube 121 and the handle 122;

[0048] The control button 113 and the camera 128 are electrically connected via a wire, and the control button 113 can control the opening and closing of the camera 128. Specifically, opening or closing the camera 128 via the control button 113 is an existing mature application, and its specific working principle will not be further elaborated here.

[0049] It should be noted that two groups of positioning grooves 124 are provided, distributed on the bottom surface of the pull handle 122, and the spacing between the two groups of positioning grooves 124 is the same as the spacing between the slide tube 121 and the handle 111, in order to achieve the fixing of the slide tube 121 by using the cooperation between the positioning block 125 and the positioning groove 124;

[0050] A disc having a diameter greater than that of the pull rod 127 is provided at the bottom of the pull rod 127 , so as to limit the range of movement of the pull rod 127 .

[0051] In this embodiment, after the guide wire tube 112 and the sliding tube 121 are inserted into the patient's body, the size and position of the wound are checked through the camera 128, and then the pull rod 127 is pulled down to disengage the positioning block 125 from the positioning groove 124, and then the pull handle 122 is pulled to drive the sliding tube 121 to move, so that the clamping assembly 21 extends from the inside of the sliding tube 121 for subsequent clamping and adjustment. At this time, the top of the positioning block 125 is aligned with another set of positioning grooves 124, and the pull rod 127 is released to allow the spring 126 to rebound, and the positioning block 125 is pushed to be inserted into the other set of positioning grooves 124 for fixation. The positioning block 125 forms a limit on the sliding tube 121 and the pull handle 122 to prevent the sliding tube 121 from moving relative to the clamping assembly 21.

[0052] Next, please refer to Figures 5 to 7The clamping assembly 21 includes a splint 211 hinged at the upper and lower ends of the inner cavity of the guide wire tube 112, and the ends of the two splints 211 close to each other are fixedly connected with a guide wire 212, and the ends of the two groups of guide wires 212 close to the handle 111 are fixedly connected with a merging wire 213, and the end of the merging wire 213 close to the handle 111 is fixedly connected with a wrench 214, and the merging wire 213 runs through the guide wire tube 112 and the handle 111, and the wrench 214 is hinged at the middle part of the handle 111, and the upper and lower ends of the inner cavity of the sliding tube 121 are provided with a sliding groove 215, and the inner cavity of the sliding groove 215 is slidably connected with a slider 216, and the ends of the two sliders 216 close to each other are fixedly connected with an elastic rope 217, and the two elastic ropes 217 are matched with the two splints 211 one by one, and the matched elastic ropes 217 and the splints 211 are fixedly connected.

[0053] Here, in the initial state, the reset elastic member is in a compressed state, and the elastic rope 217 is in a stretched state. Pressing the wrench 214 can drive the guide wire 212 and the merging wire 213 to move toward the direction close to the handle 111. At this time, the wrench 214 further compresses the reset elastic member, and the splint 211 further stretches the elastic rope 217, thereby driving the two splints 211 to rotate toward each other. Through the cooperation of the two splints 211, the bleeding point can be clamped. After the pressure on the wrench 214 is released, the splint 211, the guide wire 212 and the merging wire 213 can be driven to reset synchronously through the cooperation of the reset elastic member and the elastic rope 217.

[0054] It should be noted that both ends of the slider 216 are provided with limit rods, and the slide groove 215 is a T-shaped groove. The limit rods at both ends of the slider 216 are slidably connected in the slide groove 215 to limit the range of movement of the slider 216 and prevent the slider 216 from escaping from the slide groove 215.

[0055] In this embodiment, when the sliding tube 121 slides and extends the splint 211, the sliding tube 121 will drive the slider 216 to move together through the movement of the slide groove 215, until the slider 216 moves to the end point of the slide groove 215 and the elastic rope 217 is tightened. At this time, the tightened elastic rope 217 will pull the splint 211 to rotate, so that the splint 211 will automatically become open when it is exposed. When clamping is needed to stop bleeding, it is only necessary to rotate the wrench 214 to move the merging wire 213, pull the guide wire 212 to move, and make the two splints 211 approach each other for clamping.

[0056] Next, please refer to Figures 7 to 11The fork assembly 22 includes four rotating bars 221, and the four rotating bars 221 are respectively rotatably connected to one end of the two splints 211 away from the handle 111, and the four rotating bars 221 are adapted in pairs, and the two adapted rotating bars 221 are rotatably connected to the same splint 211, and the ends of the two adapted rotating bars 221 away from each other are fixed with a second guide wire 222, and the end of the second guide wire 222 away from the rotating bar 221 is located inside the splint 211, and the second guide wire 222 and the splint 211 are slidably connected in a clearance fit manner, and the insides of the two splints 211 are slidably connected with a second merging wire 223, and the second guide wire 222 and the second merging wire 223 located inside the same splint 211 are fixedly connected, and the end of the second merging wire 223 away from the rotating bar 221 passes through the inside of the guide wire tube 112 and is connected to the regulating assembly 23;

[0057] It should be noted that when the angle between the two matching rotating bars 221 is 0°, the fork assembly 22 is in a merged state; when the angle between the two matching rotating bars 221 is greater than 0° and less than 180°, the fork assembly 22 is in a Y-shaped state; when the angle between the two matching rotating bars 221 is 180°, the fork assembly 22 is in a T-shaped state. In the initial state, the fork assembly 22 is in a merged state, that is, the angle between the two matching rotating bars 221 is 0°, wherein, Figure 5 , Figure 7 as well as Fig.10 The rotating bar 221 shown in the figure is in different states, which is only for describing the state diagrams of the combined state and the T-shaped state, and does not constitute a specific limitation.

[0058] The regulating component 23 includes a hollow tube 231, a slide plate 232 and a driving sleeve 233. The hollow tube 231 is fixed to one end of the handle 111 away from the wire guide tube 112. A plurality of guide grooves are provided on the outer side of the hollow tube 231. The slide plate 232 is slidably connected to the inside of the hollow tube 231, and the slide plate 232 is fixedly connected to the merging wire 223. A plurality of guide bosses are provided on the outer side of the slide plate 232, and the plurality of guide bosses all penetrate the hollow tube 231 and extend to the outer side of the hollow tube 231. The driving sleeve 233 is threadedly connected to the outer side of the hollow tube 231, and the driving sleeve 233 and the slide plate 232 are rotatably connected.

[0059] Furthermore, a plurality of guide grooves are provided on the outer side of the hollow tube 231, and a plurality of guide bosses are matched with the plurality of guide grooves one by one, and the hollow tube 231 and the slide plate 232 are connected in a sliding manner through the cooperation of the guide grooves and the guide bosses; an annular groove is provided inside the drive sleeve 233, and the annular groove and the guide bosses are matched with each other, and the slide plate 232 and the drive sleeve 233 are connected in a rotating manner through the cooperation of the guide bosses and the annular grooves.

[0060] It should be noted that the outer side of the hollow tube 231 is provided with a chamfered surface, and a plurality of scale grooves 234 are evenly arranged on the chamfered surface, and the scale grooves 234 are matched with the driving sleeve 233. In the present embodiment, the plurality of scale grooves 234 are used to indicate the angle between the two matched rotating bars 221, and the scale groove 234 closest to the handle 111 is recorded as the first shape line, and the scale groove 234 farthest from the handle 111 is recorded as the third shape line. When one end of the driving sleeve 233 close to the handle 111 is matched with the first shape line, the fork assembly 22 is in a merged shape, and when one end of the driving sleeve 233 close to the handle 111 is matched with the third shape line, the fork assembly 22 is in a T-shape.

[0061] There are two groups of merging wires 223, which are respectively arranged in the inner cavities of the upper and lower groups of clamping plates 211;

[0062] The clamping plate 211 and the rotating bar 221 are made of the same material, and the clamping plate 211 and the rotating bar 221 are at the same height.

[0063] It should be noted that when the rotating bar 221 is arranged in a T-shape, its width is greater than the diameter of the slide tube 121. Therefore, when the rotating bar 221 and the clamping plate 211 are retracted into the inner cavity of the slide tube 121, the sliding tube 121 can be pushed to assist the rotating bar 221 to merge.

[0064] The outer ring of the driving sleeve 233 is provided with an anti-slip strip to facilitate the rotation of the driving sleeve 233 .

[0065] In this embodiment, before clamping and hemostasis, it is selected whether to adjust the rotating bar 221 according to the shape and number of the vascular wounds. For conventional wounds, it is not necessary to adjust the rotating bar 221, and the clamping process of the clamping plate 211 can be directly used for clamping and hemostasis. If there are a large number of wounds, it is only necessary to rotate the driving sleeve 233 to drive the slide plate 232 to move, pull the merging wire 223 to move, so that the guide wire 222 pulls the two groups of rotating bars 221 away from each other, so that the two groups of rotating bars 221 and the clamping plate 211 form a Y shape, and the distance moved by the merging wire 223 is checked through the scale groove 234, and then the rotation distance of the two groups of rotating bars 221 is known, so as to facilitate the control of the spacing between the two groups of rotating bars 221, so as to cope with the clamping and hemostasis operations of multiple groups of wounds at different positions. If the wound is long, it is only necessary to drive the slide plate 232 to move to the end point of the hollow tube 231 to fully tighten the second merging wire 223, thereby fully rotating and opening the two sets of rotating bars 221 to form a T shape with the clamping plate 211, thereby clamping the long blood vessel wound to stop bleeding.

[0066] The working principle of the present invention is as follows: after the guide wire tube 112 and the slide tube 121 are inserted into the patient's body, the size and position of the wound are checked through the camera 128, and then the pull rod 127 is pulled down to disengage the positioning block 125 from the positioning groove 124, and then the pull handle 122 is pulled to drive the slide tube 121 to move and extend the splint 211. At this time, the slide tube 121 will drive the slider 216 to move together through the movement of the slide groove 215, until the slider 216 moves to the end point of the slide groove 215, and the elastic rope 217 is tightened. At this time, the tightened elastic rope 217 will pull the splint 211 to rotate, so that the splint 211 automatically becomes an open state when it is exposed. Then, according to the shape and number of the vascular wound, it is selected whether to adjust the rotating bar 221. For a single-point bleeding hole, there is no need to adjust the rotating bar 221, and the clamping process of the splint 211 can be directly used to clamp and stop bleeding. If it is a multi-point bleeding hole, it is only necessary to rotate the driving sleeve 233 to drive the slide plate 232 to move, pull the second merging wire 223 to move, so that the second guide wire 222 pulls the two groups of rotating bars 221 away from each other, so that the two groups of rotating bars 221 and the clamping plate 211 form a Y shape, and check the distance moved by the second merging wire 223 through the scale groove 234, and then know the rotation angle of the two groups of rotating bars 221, so as to facilitate the control of the spacing between the two groups of rotating bars 221, so as to cope with the clamping and hemostasis of multiple groups of wounds at different positions. If it is a long strip bleeding hole, it is only necessary to drive the slide plate 232 to move to the end point of the hollow tube 231, so that the second merging wire 223 is fully tightened, and then the two groups of rotating bars 221 are fully rotated and opened, so that they form a T shape with the clamping plate 211, and then the long strip vascular wound can be clamped for hemostasis. After the adjustment is completed, it is only necessary to rotate the wrench 214 to move the merging wire 213, pull the guide wire 212 to move, and make the upper and lower groups of clamps 211 and the rotating bar 221 approach each other, so as to clamp and stop bleeding.
