Description

Technical Field

[0001] The present invention relates to the technical field of puncture positioning, and particularly to an adjustable anesthesia-assisted positioning puncture device for ultrasonic anesthesia. Background Technique

[0002] Puncture, a commonly used surgical term in medicine, is a diagnostic and treatment technique that inserts a puncture needle into a body cavity to extract secretions for laboratory tests, inject gas or contrast agents into the body cavity for contrast examinations, or inject drugs into the body cavity. The purpose of puncture is to draw blood for laboratory tests, transfuse blood, infuse fluids, and insert a catheter for angiography, etc.

[0003] In the existing puncture techniques, generally, corresponding operations are completed through the long-term clinical experience of doctors. However, during manual puncture, due to inevitable unexpected situations during the operation, or the doctor being overly tired and having blurred vision, or the doctor having a shaky hand, these situations may all lead to inaccurate positioning in the early stage, thus affecting the subsequent puncture effect.

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Embodiment 1. Please refer to Figures 1 - 3, an adjustable anesthesia-assisted positioning and puncture device for ultrasonic anesthesia, comprising a first cannula 1, a second cannula 2, a positioning assembly 3 and a moving assembly 4. A fixed connection is formed between the top of the first cannula 1 and the second cannula 2. A first accommodation cavity 102 and a second accommodation cavity 103 are respectively formed inside the first cannula 1, and the first accommodation cavity 102 and the second accommodation cavity 103 are communicated with each other. A first extrusion rod 101 is movably arranged inside the first accommodation cavity 102. The first extrusion rod 101 is used to extrude the positioning assembly 3, so as to drive the positioning assembly 3 to perform corresponding positioning on the human skin. The positioning assembly 3 is arranged at the front end of the first cannula 1;

[0037] A puncture needle 203 is movably arranged inside the second cannula 2. A moving assembly 4 is arranged inside the second accommodation cavity 103. The moving assembly 4 is used to drive the first extrusion rod 101 and the puncture needle 203 to perform corresponding movements, so as to complete the positioning and puncture of the human skin.

[0038] A semi-circular through groove 120 is further formed on the surface of the first extrusion rod 101 close to the positioning assembly 3. A sector plate 119 is rotatably arranged inside the semi-circular through groove 120. The positioning assembly 3 is composed of a movable rod 301, an extrusion strip 302 and a moving slide rod 304. Two movable rods 301 are provided. One end of each movable rod 301 is movably connected to the first cannula 1, and the other end of each movable rod 301 is fixedly connected to the corresponding extrusion strip 302.

[0039] The moving slide rod 304 is slidably arranged inside a third moving chute 303 through a third moving slider 306 arranged at the bottom. The third moving chute 303 is formed on the corresponding movable rod 301. The surface of the first extrusion rod 101 close to the positioning assembly 3 is also in contact with the moving slide rod 304. A sixth spring 305 is further arranged between the moving slide rod 304 and the first cannula 1.

[0040] In this embodiment: when the user needs to perform assisted anesthesia, the user only needs to place the present invention on the skin surface of the patient to be anesthetized. Since the positioning assembly 3 is arranged at the front end of the first cannula 1, after the present invention is placed on the skin surface of the patient, the extrusion strip 302 in the positioning assembly 3 will first come into contact with the patient's skin. It should be noted that the two movable rods 301 provided with the extrusion strip 302 are not only movably arranged on the first cannula 1, but also the two movable rods 301 are arranged in a V shape. And this setting is to, when the user performs puncture subsequently, extrude the moving slide rod 304 through the first extrusion rod 101, so that when the moving slide rod 304 can drive the extrusion strip 302 to move closer to the center position, so that the extrusion strip 302 can complete the positioning effect on the skin to be punctured, so as to avoid the situation that the puncture position deviates due to improper operation during subsequent puncture, so that it is necessary to perform puncture again;

[0041] It should be noted that the moving slide bar 304 is slidably arranged inside the third moving chute 303 through the third moving slider 306 provided at the bottom, and the third moving chute 303 is opened on the corresponding movable rod 301. Therefore, when the moving slide bar 304 moves under the extrusion of the first extrusion rod 101, the two movable rods 301 arranged in a V shape will move closer to the center position of the first extrusion rod 101 to complete the positioning effect on the patient's skin. At the same time, since a sixth spring 305 is also provided between the moving slide bar 304 and the first sleeve 1, when the extrusion of the first extrusion rod 101 on the moving slide bar 304 is released, the moving slide bar 304 will quickly reset through the restoring elastic force of the sixth spring 305 to release the positioning effect on the patient's skin.

[0042] Embodiment 2 is an improvement made on the basis of Embodiment 1. According to Figure 2 and Figures 4 - 10 As shown, the moving assembly 4 is composed of a moving rack 401, a flipping bar 403 and an extrusion plate 406. The moving rack 401 is fixedly connected to the surface of the second link 105 away from the first link 104. There are two flipping bars 403, and the two flipping bars 403 are symmetrically arranged with the moving rack 401 as the center. One end of each flipping bar 403 is movably connected to the corresponding fixing plate 402, and the fixing plates 402 are respectively fixedly arranged on the first extrusion rod 101.

[0043] A moving gear 408, a second extrusion rod 404 and a socket rod 405 are respectively arranged between the two flipping bars 403. The moving gear 408 is movably arranged on the fixing plate 402 through a fixedly connected shaft rod, and the shaft rod fixedly connected to the moving gear 408 is fixedly connected to the two flipping bars 403. The second extrusion rod 404 and the socket rod 405 are both fixedly arranged between the two flipping bars 403, and the extrusion plate 406 is sleeved on the socket rod 405 through the connecting through groove 407 opened.

[0044] The top of the extrusion plate 406 is also fixedly connected to one end of the fourth link 205. The other end of the fourth link 205 is slidably arranged inside the second moving chute 211 through the first moving slider 210. The second moving chute 211 is opened on the inner wall of the third sleeve 202, and a fifth spring 212 is arranged inside each second moving chute 211.

[0045] The third sleeve 202 is slidably arranged inside the first moving chute 204 through the second moving slider 213 provided on the surface. The first moving chute 204 is opened on the corresponding connecting sleeve plate 201. There are two connecting sleeve plates 201, and the two connecting sleeve plates 201 are fixedly arranged on the top surface of the second sleeve 2.

[0046] Inside the second sleeve 2, a puncture needle 203, a third limiting plate 207, and a fifth connecting rod 208 are respectively arranged. The third limiting plate 207 is fixedly arranged inside the second sleeve 2. A fourth spring 209 is also arranged between the third limiting plate 207 and the puncture needle 203. One end of the fifth connecting rod 208 is fixedly connected to the puncture needle 203.

[0047] Inside the first extrusion rod 101, a first limiting plate 106, a connecting circular plate 109, a first connecting block 112, and a second limiting plate 115 are respectively arranged. The connecting circular plate 109 is movably arranged on the side close to the positioning assembly 3. A sector plate 119 is fixedly arranged on one side surface of the connecting circular plate 109. A third connecting rod 110 is fixedly arranged on the other side surface of the connecting circular plate 109. The other end of the third connecting rod 110 is movably arranged inside the third accommodating cavity 113. The third accommodating cavity 113 is opened inside the first connecting block 112. The first connecting block 112 is movably arranged on the side of the connecting circular plate 109 away from the positioning assembly 3. A spiral groove 114 is also opened inside the third accommodating cavity 113. A second spring 111 is also arranged between the connecting circular plate 109 and the first connecting block 112.

[0048] The first limiting plate 106 is fixedly arranged inside the first extrusion rod 101. A first spring 107 is also arranged between the first limiting plate 106 and the first connecting rod 104. Both ends of the first connecting rod 104 are fixedly connected to the first connecting block 112 and the second connecting rod 105 respectively. The second limiting plates 115 are symmetrically arranged inside the first extrusion rod 101. A third spring 116 is arranged between each second limiting plate 115 and the inner wall of the first extrusion rod 101. A limiting rod 118 is also arranged at one end of the second limiting plate 115 close to the inner wall of the first extrusion rod 101. The limiting rod 118 penetrates through the first extrusion rod 101.

[0049] In this embodiment: Since a moving assembly 4 is arranged inside the first accommodating cavity 102, and a fixed connection is formed between the extrusion plate 406 in the moving assembly 4 and the fourth connecting rod 205 movably arranged inside the third sleeve 202. The third sleeve 202 is not only slidably arranged inside the first moving chute 204 opened inside the connecting sleeve plate 201 through the second moving slider 213, but also fixedly connected to the output end of an external cylinder. Therefore, when the user starts the corresponding external cylinder, at this time, the third sleeve 202 will slide inside the first moving chute 204 to drive the extrusion plate 406 to move synchronously.

[0050] When the pressing plate 406 moves, since the pressing plate 406 is sleeved inside the socket rod 405 through the connecting through slot 407, and the socket rod 405 and the second pressing rod 404 are fixedly arranged between the two flipping bars 403, when the pressing plate 406 moves, the front end of the pressing plate 406 will press the second pressing rod 404, thereby driving the corresponding movement of the flipping bar 403. The flipping bar 403 is movably connected to the fixing plate 402, and the fixing plate 402 is fixedly arranged on the first pressing rod 101. Therefore, when the flipping bar 403 moves, the first pressing rod 101 will also move synchronously. After the first pressing rod 101 moves, the first pressing rod 101 can complete the pressing effect on the moving slide rod 304, so that the positioning component 3 can complete the corresponding positioning effect;

[0051] Meanwhile, since a sector plate 119 is also arranged at one end of the first pressing rod 101 close to the positioning component 3, and the sector plate 119 is rotatably arranged inside the semi-circular through slot 120, and the sector plate 119 is fixedly connected to the connecting circular plate 109 movably arranged inside the first accommodation cavity 102. Therefore, when the first pressing rod 101 presses the moving slide rod 304, the sector plate 119 will also move closer to the patient's skin. When the sector plate 119 contacts the patient's skin, at this time, the sector plate 119 will retract into the first accommodation cavity 102 under the contact action of the patient's skin, so as to drive the connecting circular plate 109 to move away from the positioning component 3 inside the first accommodation cavity 102. Through this contact and retraction setting, the user can also judge the specific puncture time according to the actual situation of the user. Because when the sector plate 119 retracts, the moving component 4 will stop pressing the first pressing rod 101, and then press the puncture needle 203 arranged inside the second sleeve 2, so that the puncture needle 203 extends out of the second sleeve 2, thereby completing the corresponding puncture effect. And this way of positioning first and then puncturing also ensures that the puncture can be carried out more effectively, so as to complete the corresponding puncture effect in a more stable puncture state;

[0052] It should be noted that when the connecting circular plate 109 moves synchronously under the retraction action of the sector plate 119, on the one hand, the other surface of the connecting circular plate 109 is movably arranged inside the third accommodation cavity 113 through the third connecting rod 110. The third accommodation cavity 113 is opened inside the first connecting block 112, and the third connecting rod 110 arranged inside the third accommodation cavity 113 is also slidably arranged on the spiral groove 114 opened inside the third accommodation cavity 113 through the connecting slider;

[0053] Therefore, after the connecting circular plate 109 is moved, the connecting circular plate 109 will rotate accordingly under the rotational action between the connecting slider and the spiral groove 114, thereby driving the sector plate 119 to rotate correspondingly inside the corresponding semi-circular through groove 120. When the sector plate 119 rotates, since a cleaning plate is also provided on the sector plate 119 and a cotton cloth for disinfecting such as adhering iodine is sleeved on the cleaning plate, when the sector plate 119 rotates, the cleaning plate will rotate synchronously under the rotational action of the sector plate 119, so that the sector plate 119 can disinfect the skin to be punctured accordingly, so that the subsequent puncture can be carried out more effectively;

[0054] On the other hand, due to the relatively high frictional force between the first connecting block 112 and the first receiving cavity 102, the first connecting block 112 will not move inside the first receiving cavity 102 before the third connecting rod 110 finishes rotating. After the third connecting rod 110 finishes rotating, the third connecting rod 110 will squeeze the first connecting block 112, thereby driving the first connecting block 112 to move away from the positioning assembly 3;

[0055] After the first connecting block 112 moves, since the first connecting block 112 is also fixedly connected to the second connecting rod 105 through the first connecting rod 104, and a first spring 107 is provided between the first connecting rod 104 and the first limiting plate 106, when the first connecting rod 104 moves synchronously under the movement of the first connecting block 112, at this time the first spring 107 will be squeezed. The setting of the first spring 107 can not only ensure that the first connecting rod 104, the first connecting block 112 and the connecting circular plate 109 can all be in a fixed state inside the first receiving cavity 102 by the elastic force of the first spring 107 in the initial position, so that the sector plate 119 can extend out of the first sleeve 1 to complete the corresponding contact positioning effect, but also after the subsequent puncture is completed, the sector plate 119, the first connecting block 112 and the connecting circular plate 109 can all be quickly reset by the reset elastic force of the first spring 107;

[0056] At the same time, since the other end of the second connecting rod 105 is fixedly connected to the moving rack 401, and the moving rack 401 is also meshed with the moving gear 408 fixedly arranged on the flipping bar 403 through a shaft rod, when the second connecting rod 105 moves, the moving rack 401 will drive the moving gear 408 to rotate, thereby driving the flipping bar 403 to rotate correspondingly;

[0057] When the flipping bar 403 rotates, since the movement of the pressing plate 406 will not stop due to the rotation of the flipping bar 403, the pressing plate 406 will, under the action of the rotation of the flipping bar 403, change from the running state on the same horizontal line as the moving gear 408 to the running state parallel to the moving gear 408. This setting is for two purposes. On the one hand, it is to stop the pressing and moving of the first pressing rod 101, so that the positioning component 3 can complete the corresponding positioning. On the other hand, when the pressing plate 406 is in a state parallel to the first pressing rod 101, the pressing plate 406 can also complete the pressing of the puncture needle 203 inside the second sleeve 2 without stopping, so as to complete the corresponding puncture;

[0058] It should be noted that since second limiting plates 115 are symmetrically arranged inside the first pressing rod 101, limiting rods 118 are arranged on each second limiting plate 115, and the limiting rods 118 all penetrate the first pressing rod 101. And the limiting rods 118 are arranged inside the limiting grooves 117 in the initial state, and the limiting grooves 117 are opened on the inner wall of the first accommodating cavity 102. A plurality of limiting grooves 117 are opened and are adjacent to each other, and an arc surface is arranged between adjacent limiting grooves 117. Through this setting, when the first pressing rod 101 moves, the limiting rods 118 will slide from the inner wall of one limiting groove 117 into another limiting groove 117, and the arrangement of the arc surface will not affect the sliding of the limiting rods 118, avoiding the situation of jamming and immobility. At the same time, a third spring 116 is arranged between the second limiting plate 115 and the inner wall of the first pressing rod 101, and the arrangement of the third spring 116 is also to enable the limiting rods 118 to slide smoothly through the elastic force of the third spring 116 after the limiting rods 118 move;

[0059] When the first pressing rod 101 no longer receives the extrusion of the pressing plate 406 and stops moving, the limiting rods 118 will also be stuck inside the corresponding limiting grooves 117, so that the first pressing rod 101 can maintain a stable state, so as to prevent the first pressing rod 101 from retracting after no longer receiving the extrusion of the pressing plate 406, thus affecting the positioning effect of the positioning component 3;

[0060] It should be noted that since the fourth link 205 fixedly connected to the extrusion plate 406 is slidably disposed inside the second moving chute 211 formed inside the third sleeve 202 through the corresponding first moving slider 210, when the extrusion plate 406 changes from the operating state on the same horizontal line as the moving gear 408 to the operating state parallel to the moving gear 408, the upward sliding of the first moving slider 210 can also make the transformation of the extrusion plate 406 proceed more smoothly. Moreover, a fifth spring 212 is also disposed inside the second moving chute 211. Therefore, when the subsequent extrusion plate 406 is reset and changes from the parallel state with the first extrusion rod 101 to the horizontal state again, it can be quickly achieved by the elastic force of the fifth spring 212;

[0061] Through the above settings, not only can this solution first perform positioning and then puncture under the action of the moving component 4 so that the puncture effect is more stable and effective, but also when the moving component 4 is reset, the puncture needle 203 can be reset first, and then the positioning component 3 can be reset, so that this solution can be carried out more safely, avoiding the positioning component 3 becoming loose during the reset process of the puncture needle 203, thereby causing unnecessary damage to the patient by the puncture needle 203.

[0062] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0063] The above are only the preferred embodiments of the present invention.
