Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of medical devices, and particularly relates to an endoscopic hemostasis device for thoracic surgery. BACKGROUND

[0002] In the field of thoracic surgery, hemostasis operation is a key link to ensure the success of the operation and the safety of the patient. With the continuous progress of medical technology, endoscopic technology is increasingly widely used in thoracic surgery, which enables the operation to be performed under a smaller incision, reducing the trauma to the patient's body. The endoscopic hemostasis device is also constantly developing, but there are still many problems to be solved.

[0003] The existing hemostasis device has obvious limitations in actual application. Most of the hemostasis devices are designed for hole-shaped bleeding points and achieve hemostasis through mechanical clamping. However, in the complex environment of thoracic surgery, the shape of the bleeding point is not single hole. For example, in lung surgery, due to the removal of diseased tissue, separation of blood vessels and other operations, long strip-shaped bleeding points often occur. In this case, the existing hemostasis device is not up to the task and often needs multiple hemostasis devices to cooperate to complete the hemostasis operation, which not only increases the complexity of the operation, but also occupies more operation space due to the use of multiple devices, making the operation more difficult.

[0004] In addition, when multiple bleeding points occur during the operation, the existing hemostasis device needs to clamp each bleeding point one by one, which means that more hemostasis devices are needed, and multiple medical staff need to operate simultaneously during the operation. This way of multi-person gathering operation not only increases the cooperation difficulty between medical staff, but also causes the medical staff in the operation area to gather too much. At the same time, too many personnel and equipment concentrated in the limited operation area will also seriously affect the operation field of vision, further increasing the difficulty of the operation, prolonging the operation time and reducing the operation efficiency.

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

[0047] The outer tube assembly 12 comprises a sliding tube 121 sleeved movably outside the guide wire tube 112, a pull handle 122 fixedly connected to the bottom of one end of the sliding tube 121 close to the handle 111, a limiting tube 123 fixedly connected to the bottom surface of the handle 111, the pull handle 122 being slidingly connected in the inner cavity of the limiting tube 123, two groups of positioning grooves 124 being formed in the bottom surface of the pull handle 122, a positioning block 125 being slidingly connected in the inner cavity of the limiting tube 123, a spring 126 being assembled between the positioning block 125 and the limiting tube 123, the positioning block 125 being matched with the positioning grooves 124, a pull rod 127 being fixedly connected to the bottom of the positioning block 125 and located in the inner circle of the spring 126, the lower end of the pull rod 127 penetrating through the limiting tube 123, and a camera 128 being fixedly installed in the inner cavity of the end of the sliding tube 121 away from the handle 111, wherein when the upper end of the positioning block 125 is clamped in the positioning grooves 124, the positioning block 125 can limit the sliding tube 121 and the pull handle 122; when the positioning block 125 and the positioning grooves 124 are disengaged from each other, the positioning block 125 releases the limitation on the sliding tube 121 and the pull handle 122.

[0048] The control knob 113 and the camera 128 are electrically connected through wires, and the control knob 113 can control the opening and closing of the camera 128. Specifically, the opening and closing of the camera 128 through the control knob 113 is a mature application, and its specific working principle will not be described further here.

[0049] It should be noted that the positioning grooves 124 are provided in two groups and 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 sliding tube 121 and the handle 111, so as to realize the fixation of the sliding tube 121 by matching the positioning block 125 with the positioning grooves 124.

[0050] The bottom of the pull rod 127 is provided with a disc with a diameter larger than that of the pull rod 127, so as to limit the movement range 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 observed through the camera 128, then the pull rod 127 is pulled down to make the positioning block 125 disengage from the positioning grooves 124, and then the pull handle 122 is pulled to drive the sliding tube 121 to move, so that the clamping assembly 21 is extended from the inner part of the sliding tube 121 for subsequent clamping and adjustment. At this time, the top of the positioning block 125 is aligned with the other group of positioning grooves 124, the pull rod 127 is released to make the spring 126 rebound to push the positioning block 125 to insert into the other group of positioning grooves 124 for fixation. The positioning block 125 limits the sliding tube 121 and the pull handle 122, so as to avoid the movement of the sliding tube 121 relative to the clamping assembly 21.

[0052] Secondly, please refer to Figures 5 to 7The clamping assembly 21 comprises two clamping plates 211 hingedly connected to the upper end and the lower end of the guide wire tube 112, and each of the two clamping plates 211 is fixedly connected with a guide wire I 212 at the end close to the other, and the two groups of guide wire I 212 are fixedly connected with a combined wire I 213 at the end close to the handle 111, and the combined wire I 213 is fixedly connected with a wrench 214 at the end close to the handle 111, and the combined wire I 213 penetrates through the inside of the guide wire tube 112 and the handle 111, and the wrench 214 is hingedly connected to the middle part of the handle 111, and the upper end and the lower end of the inner cavity of the sliding tube 121 are both provided with a sliding groove 215, and the inner cavity of the sliding groove 215 is slidably connected with a sliding block 216, and the end of each of the two sliding blocks 216 close to the other is fixedly connected with an elastic cord 217, and the two elastic cords 217 and the two clamping plates 211 are matched one by one, and the matched elastic cord 217 and the clamping plate 211 are fixedly connected.

[0053] Here, in the initial state, the reset elastic member is in a compressed state, and the elastic cord 217 is in a stretched state, and pressing the wrench 214 can drive the guide wire I 212 and the combined wire I 213 to move towards the handle 111, at this time, the wrench 214 further compresses the reset elastic member, and the clamping plate 211 further stretches the elastic cord 217, thereby driving the two clamping plates 211 to rotate towards each other, and through the cooperation of the two clamping plates 211, the bleeding point can be clamped, and after the pressing of the wrench 214 is released, through the cooperation of the reset elastic member and the elastic cord 217, the clamping plate 211, the guide wire I 212 and the combined wire I 213 can be driven to reset synchronously.

[0054] It should be noted that the two ends of the sliding block 216 are provided with a limiting rod, and the sliding groove 215 is a T-shaped groove, and the limiting rods at the two ends of the sliding block 216 are slidably connected in the sliding groove 215, which is designed to limit the movement range of the sliding block 216 and prevent the sliding block 216 from disengaging from the sliding groove 215.

[0055] In this embodiment, when the sliding tube 121 slides and the clamping plate 211 is stretched out, the sliding tube 121 will move the sliding block 216 through the sliding groove 215 until the sliding block 216 moves to the end point of the sliding groove 215, and the elastic cord 217 is taut, at this time, the taut elastic cord 217 will pull the clamping plate 211 to rotate, so that the clamping plate 211 automatically becomes open when it is exposed, and when hemostasis is needed, only the combined wire I 213 is moved by rotating the wrench 214 to pull the guide wire I 212 to move, so that the two clamping plates 211 are close to each other, and clamping can be performed.

[0056] Secondly, please refer again to Figures 7 to 11The bifurcated assembly 22 comprises four rotating bars 221, the four rotating bars 221 are rotationally connected to the ends of the two clamping plates 211 away from the handle 111 respectively, the two rotating bars 221 adapted to each other are rotationally connected to the same clamping plate 211, the ends of the two rotating bars 221 adapted to each other away from each other are fixedly connected with guide wires two 222, the ends of the guide wires two 222 away from the rotating bars 221 are located inside the clamping plates 211, and the guide wires two 222 and the clamping plates 211 are slidingly connected in a clearance fit manner, the inside of the two clamping plates 211 is slidingly connected with the combined wires two 223, and the guide wires two 222 and the combined wires two 223 fixedly connected between the inside of the same clamping plate 211, and the end of the combined wires two 223 away from the rotating bar 221 penetrates the inside of the guide wire tube 112 and is connected with the control assembly 23;

[0057] It should be noted that when the included angle between the two rotating bars 221 adapted to each other is 0°, the bifurcated assembly 22 is in a combined state; when the included angle between the two rotating bars 221 adapted to each other is greater than 0° and less than 180°, the bifurcated assembly 22 is in a Y-shaped state; when the included angle between the two rotating bars 221 adapted to each other is 180°, the bifurcated assembly 22 is in a T-shaped state, and in the initial state, the bifurcated assembly 22 is in a combined state, that is, the included angle between the two rotating bars 221 adapted to each other is 0°, wherein, Figure 5 、 Figure 7 and Figure 10 The rotating bars 221 shown in the above are in different states, which are only for expressing the state diagrams of the combined state and the T-shaped state, and do not constitute specific limitation.

[0058] The control assembly 23 comprises a hollow tube 231, a sliding plate 232 and a driving sleeve 233, the hollow tube 231 is fixed to the end of the handle 111 away from the guide wire tube 112, a plurality of guide grooves are formed on the outer side of the hollow tube 231, the sliding plate 232 is slidingly connected to the inside of the hollow tube 231, and the sliding plate 232 and the combined wires two 223 are fixedly connected, a plurality of guide bosses are arranged on the outer side of the sliding plate 232, and the plurality of guide bosses penetrate the hollow tube 231 and extend to the outside of the hollow tube 231, and the driving sleeve 233 is threadedly connected to the outer side of the hollow tube 231, and the driving sleeve 233 and the sliding plate 232 are rotationally connected;

[0059] Further, a plurality of guide grooves are formed on the outer side of the hollow tube 231, the plurality of guide bosses and the plurality of guide grooves are adapted to each other, and the hollow tube 231 and the sliding plate 232 are slidingly connected through the cooperation of the guide grooves and the guide bosses; the inside of the driving sleeve 233 is provided with an annular recess, and the annular recess is adapted to the guide boss, and the sliding plate 232 and the driving sleeve 233 are rotationally connected through the cooperation of the guide boss and the annular recess.

[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 uniformly arranged on the chamfered surface, and the scale grooves 234 are matched with the driving sleeve 233. In this embodiment, the plurality of scale grooves 234 are used to indicate the included angle between the two matched rotating bars 221. The scale groove 234 closest to the handle 111 is recorded as the first mode line, and the scale groove 234 farthest from the handle 111 is recorded as the third mode line. When the end of the driving sleeve 233 close to the handle 111 is matched with the first mode line, the bifurcated assembly 22 is in the merged mode. When the end of the driving sleeve 233 close to the handle 111 is matched with the third mode line, the bifurcated assembly 22 is in the T-shaped mode.

[0061] The two groups of merged wires two 223 are arranged in the inner cavities of the upper and lower clamping plates 211.

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

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

[0064] The outer circle of the driving sleeve 233 is provided with an anti-skid strip, which is designed to facilitate the rotation of the driving sleeve 233.

[0065] In this embodiment, before clamping and hemostasis is performed, whether to control the rotating bar 221 is selected according to the shape and number of the blood vessel wounds. For conventional wounds, the rotating bar 221 does not need to be adjusted, and the clamping process of the clamping plate 211 can be directly used for clamping and hemostasis. If the number of wounds is large, the sliding plate 232 is only needed to be moved by rotating the driving sleeve 233, the merged wire two 223 is pulled to move, the guide wire two 222 is pulled to move to make the two groups of rotating bars 221 move away from each other, the two groups of rotating bars 221 form a Y-shaped mode with the clamping plate 211, and the distance moved by the merged wire two 223 is checked through the scale groove 234, so as to know the rotating distance of the two groups of rotating bars 221, and the distance between the two groups of rotating bars 221 is controlled, so as to deal with the clamping and hemostasis operation of multiple wounds at different positions. If the wound is long strip-shaped, the sliding plate 232 is only needed to be moved to the end point of the hollow tube 231, so that the merged wire two 223 is completely pulled tight, and then the two groups of rotating bars 221 are completely rotated and opened, so that they form a T-shaped mode with the clamping plate 211, and then the long strip-shaped blood vessel wound can be clamped for hemostasis.

[0066] The working principle of the present application is as follows: 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 observed through the camera 128, then the pull rod 127 is pulled down to make the positioning block 125 disengage from the positioning groove 124, and then the pull handle 122 is pulled to drive the sliding tube 121 to move and extend the clamping plate 211. At this time, the sliding tube 121 will move through the sliding groove 215, driving the sliding block 216 to move together until the sliding block 216 moves to the end point of the sliding groove 215, and the elastic rope 217 is taut, at which time the taut elastic rope 217 will pull the clamping plate 211 to rotate, so that the clamping plate 211 is automatically in an open state when it is exposed. Then, according to the shape and number of the blood vessel wound, it is determined whether to adjust the rotating bar 221, and for single-point bleeding, the rotating bar 221 does not need to be adjusted, and the clamping and hemostasis process using the clamping plate 211 can be directly performed. If it is a multi-point bleeding, only the driving sleeve 233 is rotated to drive the sliding plate 232 to move, the combined wire two 223 is pulled to move, the guide wire two 222 is pulled to move, the two groups of rotating bars 221 are pulled away from each other, the two groups of rotating bars 221 form a Y shape with the clamping plate 211, and the distance moved by the combined wire two 223 is observed through the scale groove 234, so as to know the angle of rotation of the two groups of rotating bars 221, so as to control the distance between the two groups of rotating bars 221, thereby coping with the clamping and hemostasis operation of multiple wounds at different positions. If it is a long strip-shaped bleeding, only the sliding plate 232 is driven to move to the end point of the hollow tube 231, so that the combined wire two 223 is completely taut, and then the two groups of rotating bars 221 are completely rotated and opened, so that they form a T shape with the clamping plate 211, and then the long strip-shaped blood vessel wound can be clamped and hemostasis. After the adjustment is completed, the combined wire one 213 is rotated to move, the guide wire one 212 is pulled to move, and the upper and lower two groups of clamping plates 211 and rotating bars 221 are moved close to each other, so that the clamping and hemostasis can be performed.
