[0039] See also Figure 1-Figure 3 An auxiliary fixing mechanism for a puncture needle is provided in one embodiment of the present application. The auxiliary fixing mechanism for a puncture needle includes an adapter 100. The adapter 100 includes a first clamping portion 110 and a second clamping portion 120 that are rotatably connected. The first clamping portion 110 and the second clamping portion 120 are respectively provided with clamping grooves 130. The two clamping grooves 130 are used to clamp the puncture needle 12. A locking structure 140 is provided on one of the first clamping portion 110 and the second clamping portion 120, and a matching structure 150 that matches the locking structure 140 is provided on the other.

[0040] In this embodiment, when the first clamping portion 110 or the second clamping portion 120 rotates away from each other, the adapter 100 is opened. Figure 2At this time, any position on the puncture needle 12 can be embedded in any clamping groove 130; when the first clamping portion 110 or the second clamping portion 120 rotates toward the side close to each other, so that the two clamping grooves 130 are closed, the locking structure 140 is matched with the matching structure 150, and the adapter 100 is closed. Figure 3 The puncture needle 12 is fastened between the two clamping grooves 130. That is, when in use, the puncture needle 12 can be directly clamped between the two clamping grooves 130 by rotating the first clamping part 110 or the second clamping part 120, which is convenient and fast to install. When disassembling, the first clamping part 110 and the second clamping part 120 can be rotated in the opposite direction, which is also convenient to disassemble.

[0041] The first clamping portion 110 and the second clamping portion 120 are rotatably connected via a rotating shaft.

[0042] In some embodiments, the first clamping portion 110 and the second clamping portion 120 respectively include a deformation portion 111 capable of elastic deformation, and the clamping groove 130 is opened on the deformation portion 111. Along the length direction of the puncture needle 12, the diameter of at least part of the clamping groove 130 is smaller than the diameter of the puncture needle 12.

[0043] The deformable portion 111 can be elastically deformed, such as soft rubber. Along the length direction of the puncture needle 12, the diameter of at least part of the clamping groove 130 is smaller than the diameter of the puncture needle 12. That is, when the clamping groove 130 clamps the puncture needle 12, since the side wall material of the clamping groove 130 is relatively soft and deformable, the puncture needle 12 can be pressed into the clamping groove 130 whose diameter is smaller than the puncture needle 12, thereby clamping the puncture needle 12 through the clamping groove 130.

[0044] Of course, the deformation portion 111 may also be deformed by an elastic member. For example, the clamping groove 130 is located between two elastic members, and the puncture needle 12 can be clamped by the two elastic members.

[0045] Furthermore, the adapter has an upper end surface 170 and a lower end surface 180, and the diameter of the clamping groove 130 gradually decreases along the direction from the upper end surface 170 to the lower end surface 180, and the minimum diameter of the clamping groove 130 is smaller than the diameter of the puncture needle 12. The direction from the root to the tip of the puncture needle 12 is consistent with the direction from the upper end surface to the lower end surface, and the user can change the use direction of the adapter according to needs during use.

[0046] In this embodiment, the clamping groove 130 is a V-shaped structure, which is used to locate the center of the puncture needle 12. Along the direction from the upper end surface 170 to the lower end surface 180, the diameter of the clamping groove 130 gradually decreases, and the end with a larger diameter of the clamping groove 130 facilitates the insertion of the puncture needle 12, and the end with a smaller diameter is used to clamp and fix the puncture needle 12.

[0047] In addition, the diameter of the clamping groove 130 gradually decreases, which is also convenient for adapting to puncture needles 12 of different diameters, further improving the applicability of the adapter 100.

[0048] In some embodiments, a limiting structure 160 is disposed between the upper end surface 170 and the lower end surface 180, and the limiting structure 160 is used to cooperate with the matching structure 13 of the puncture device. Figure 2 Two protrusions arranged at intervals along the length direction of the puncture needle 12 are respectively arranged outside the first clamping part 110 and outside the second clamping part 120, and a groove is formed between the two protrusions, which is a limiting structure 160. A matching structure 13 is arranged on the puncture frame 11 of the puncture device, and the matching structure 13 is clamped between adjacent limiting structures 160 to clamp the adapter 100. The protrusion on the first clamping part 110 extends outwardly along the radial direction of the first clamping part 110, and the protrusion on the second clamping part 120 extends outwardly along the radial direction of the second clamping part 120.

[0049] Of course, the limiting structure can also be a protrusion arranged on the first clamping part and the second clamping part, and a groove is arranged on the matching structure. The limiting structure cooperates with the matching structure and can be clamped by the matching structure.

[0050] Specifically, the upper end surface 170 and / or the lower end surface 180 are provided with marks, and the marks are used to indicate the insertion direction of the puncture needle 12. For example, upward words, English letters or upward arrows are marked on the upper end surface 170.

[0051] In some embodiments, the first clamping portion 110 and the second clamping portion 120 respectively include a fixing portion 112, the hardness of the fixing portion 112 is greater than that of the deformation portion 111, the fixing portion 112 is semi-surrounded by the deformation portion 111, and the fixing portion 112 of the first clamping portion 110 is rotatably connected to the fixing portion 112 of the second clamping portion 120.

[0052] The fixing part 112 has a greater hardness than the deformation part 111 , for example, the fixing part 112 may be made of hard rubber, metal, or ceramic. The fixing part 112 is used to drive the deformation part 111 to rotate so that the clamping grooves 130 on the two deformation parts 111 clamp the puncture needle 12 .

[0053] Specifically, after the locking structure 140 and the matching structure 150 lock the adapter 100 in a closed state, the deformable portion 111 contacts the puncture needle 12, and the squeezing force of the fixing portion 112 on the deformable portion 111 generates friction between the adapter and the puncture needle, thereby clamping the puncture needle.

[0054] In some embodiments, the first clamping portion 110 has a first clamping plane 113, the second clamping portion 120 has a second clamping plane 121, the locking structure 140 is a lock buckle arranged on one of the fixing portions 112, and the matching structure 150 is a lock groove arranged on the other fixing portion 112. When the first clamping plane 113 is in contact with the second clamping plane 121, the lock buckle is used to buckle into the lock groove.

[0055] In this embodiment, when the first clamping portion 110 or the second clamping portion 120 rotates toward the side close to each other so that the first clamping plane 113 and the second clamping plane 121 are in contact with each other, the notch of one of the two clamping grooves 130 is connected with the notch of the other clamping groove 130. At this time, the two clamping grooves 130 form a closed hole for clamping the puncture needle 12. For example, the clamping groove 130 is a semicircular structure. When the first clamping plane 113 and the second clamping plane 121 are in contact with each other, the two semicircular clamping grooves 130 form a circular hole, and the puncture needle 12 is clamped in the circular hole.

[0056] When the first clamping plane 113 and the second clamping plane 121 are in contact with each other, the lock buckle is used to buckle into the lock groove, thereby directly locking the first clamping portion 110 and the second clamping portion 120. The lock buckle can be various elastic lock buckles in the prior art, which will not be described in detail here.

[0057] In some embodiments, at least one fixing portion 112 is provided with a groove 1121. Two fixing portions 112 are provided with grooves 1121, and the grooves 1121 are used to reduce the rigidity of the fixing portion 112, so that when the lock buckle is buckled into the lock slot, the fixing portion 112 is more easily deformed, so that the lock buckle can be quickly buckled into the lock slot.

[0058] In some embodiments, the puncture needle auxiliary fixing mechanism includes a needle guide 200, which includes a body 210 and a fastener 220 connected to the body 210. A guide hole 211 is opened in the body 210, and the fastener 220 is used to limit the free movement of the needle guide 200 on the puncture needle 12.

[0059] In this embodiment, combined with Figure 4-Figure 8 After the adapter 100 is fixed to the root of the puncture needle 12, the puncture needle 12 is passed through the guide hole 211 in the center of the needle guide 200 and the fastener 220 in sequence, and the body 210 is suspended on the tip of the puncture needle 12 through the fastener 220. After the needle guide 200 is connected to the puncture frame 11 of the puncture device, the puncture frame 11 can guide and position the tip of the puncture needle 12 through the needle guide 200.

[0060] Specifically, the needle guide 200 includes a first limiting ring 240 and a second limiting ring 250, which are respectively arranged outside the body 210, and the first limiting ring 240 and the second limiting ring 250 are arranged at intervals along the axial direction. In actual use, the matching structure 13 of the puncture device is used to clamp between the first limiting ring 240 and the second limiting ring 250 to fix the needle guide 200 on the puncture device. The first limiting ring 240 and / or the second limiting ring 250 are manufactured separately, and after manufacturing, they are sleeved outside the body 210, or are directly formed integrally with the body 210.

[0061] In some embodiments, in combination Figure 4 and Figure 5 The fastener 220 is a rubber sleeve 221 , which is wrapped around one end of the body 210 along the guide hole 211 to block one end of the guide hole 211 .

[0062] In this embodiment, the rubber sleeve 221 can be a soft rubber sleeve that facilitates the puncture of the puncture needle 12. The rubber sleeve 221 and the needle guide 200 are two parts. After cleaning, the rubber sleeve 221 is sleeved on the outside of one end of the body 210. After the adapter 100 and the root of the puncture needle 12 are fixed, the puncture needle 12 is passed through the guide hole 211 in the center of the needle guide 200, and the puncture needle 12 pierces the rubber sleeve 221 and is exposed. Since the rubber sleeve 221 itself is elastic, after the puncture needle 12 pierces the rubber sleeve 221, it is kept together with the puncture needle 12 under the elastic binding force of the rubber sleeve 221, and will not fall under the action of gravity, thereby avoiding the ground contamination of the needle guide 200.

[0063] In some other embodiments, in combination Figure 6 and Figure 7 The fastener 220 is an elastic body 222, which is arranged outside one end of the body 210 along the guide hole 211. A through hole 2221 connected to the guide hole 211 is opened in the elastic body 222, and the diameter of the through hole 2221 is smaller than the diameter of the puncture needle 12.

[0064] In this embodiment, the main body 210 and the elastic body 222 are formed into a part by injection molding. A through hole 2221 is provided in the center of the elastic body 222. The size of the through hole 2221 is smaller than the outer diameter of the puncture needle 12. The size of the through hole 2221 can be set according to different models of the puncture needle 12. After the adapter 100 is fixed to the root of the puncture needle 12, the puncture needle 12 is passed through the guide hole 211 in the center of the needle guide 200 and the through hole 2221 in the center of the elastic body 222 in sequence and then exposed. Since the elastic body 222 itself is elastic, after the puncture needle 12 passes through the elastic body 222, it is kept together with the puncture needle 12 under the elastic binding force of the elastic body 222, and will not fall under the action of gravity, thereby avoiding the ground contamination of the needle guide 200.

[0065] Furthermore, in order to increase the elastic binding force of the elastic body 222 on the puncture needle 12, the height of the elastic body 222 may be increased so as to increase the contact area between the elastic body 222 and the puncture needle 12 and increase the friction between the two.

[0066] The elastomer may be made of at least one of silicone, TPE, TPU and rubber.

[0067] In some other embodiments, combined with Figure 8 The fastener 220 is a telescopic member 223 , one end of the telescopic member 223 is connected to the adapter 100 , and the other end is connected to the needle guide 200 .

[0068] In this embodiment, the telescopic member 223 can be a telescopic rod, an elastic rope, or an elastic band. For example, the telescopic member 223 is an elastic rope. The adapter 100 and the needle guide 200 are connected by an elastic rope, and the elastic rope can be extended or retracted. When in use, the adapter 100 is first fixed to the root of the puncture needle 12. At this time, the needle guide 200 and the adapter 100 are connected by an elastic rope, and the needle guide 200 will not fall. After the adapter 100 is installed, the needle guide 200 is pulled hard along the direction of the puncture needle 12. Under the action of the force, the elastic rope will stretch. At this time, the puncture needle 12 is aligned with the guide hole 211 in the middle of the needle guide 200, and the puncture needle 12 is inserted into the guide hole 211. The needle guide 200 is released, and the elastic rope retracts. Under the tension of the rope, the needle guide 200 and the puncture needle 12 are installed together. After installation, the needle guide 200 is connected to the adapter 100 under the action of the rope, and will not fall due to gravity.

[0069] The adapter 100 and the needle guide 200 are both disposable sterile instruments, and are used together with the puncture needle 12 of the corresponding model during surgery.

[0070] Combined, 1 and Fig. 9 An embodiment of the present application further provides a puncture device, which includes a puncture frame 11, one end of a puncture needle 12 is fixed to the puncture frame 11 through an adapter 100, and the other end of the puncture needle 12 is fixed to the puncture frame 11 through a needle guide 200.

[0071] The root of the puncture needle 12 can be fixed on the puncture frame 11 through the adapter 100 , and the needle portion of the puncture needle 12 can be fixed on the puncture frame 11 through the needle guide 200 .

[0072] In this embodiment, the puncture frame 11 has two matching structures 13, which are detachably connected to the adapter 100 and the needle guide 200, respectively, and are used to fix the adapter 100 and the needle guide 200, respectively. The fixing method of the matching structure 13 includes but is not limited to buckle fixing, clamping fixing, and screw fixing. For example, Fig. 9In the embodiment, the matching structure 13 includes two arc-shaped clamping structures, and the adapter 100 is clamped between the limiting structures 160 by the two arc-shaped structures.

[0073] When in use, the auxiliary fixing mechanism for the puncture needle is first fixed to the puncture needle 12, and then connected to the adapter 100 and the needle guide 200 respectively through the two matching structures 13, so as to fix the root and the tip of the puncture needle 12 respectively, thereby achieving the fixing and guiding effect on the puncture needle 12. After the puncture operation is completed, the auxiliary fixing mechanism for the puncture needle is removed.

[0074] In some embodiments, a manual control is provided on the puncture device, and the manual control is triggered to manually clamp or release the auxiliary fixing mechanism of the puncture needle. The manual control can be used to release the puncture needle in an emergency when the power is off.

[0075] In some embodiments, an instrument confirmation control 14 is provided on the puncture device. When the instrument confirmation control is triggered, the puncture device drives the puncture needle 12 to puncture.

[0076] The manual control and the instrument confirmation control 14 can be any one of a button or a knob.

[0077] An embodiment of the present application further provides a puncture surgical robot, which includes a robotic arm and a puncture device, wherein the puncture device is disposed on the robotic arm.

[0078] In actual use, when the puncture needle is installed on the puncture rack 11 through the puncture needle auxiliary fixing mechanism, the instrument confirmation control can be triggered.
