Therefore, those of ordinary skill in the art should realize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present invention. Likewise, for clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.
参考图1、图2、图3、图4以及图5所示，本发明的具有手位的穿刺针，包括：外针组件2，外针组件2包括外针座21以及位于外针座21一端的外针22，外针座21的外壁上凸出设置有用于辅助穿刺操作的手位211。该穿刺针在使用时，手术人员通过手位211，能够将所述穿刺针稳固持住，而且操作方便，在推送该穿刺针时持住手位211，能够更好的推压施力，更加安全的进行穿刺，且在准备穿刺手术前，由于手位211的阻挡，穿刺针可以稳固地放置在手术台上，不会轻易滚落。With reference to Figure 1, Figure 2, Figure 3, Figure 4 and Figure 5, the puncture needle with hand position of the present invention includes: an outer needle assembly 2 including an outer needle seat 21 and an outer needle seat 21 At one end of the outer needle 22, a hand position 211 for assisting the puncture operation is protrudingly provided on the outer wall of the outer needle seat 21. When the puncture needle is in use, the operator can firmly hold the puncture needle through the hand position 211, and the operation is convenient. When the puncture needle is pushed, the hand position 211 can be held, which can better push and apply force, and is safer Before the puncture operation is prepared, the puncture needle can be firmly placed on the operating table and will not roll off easily due to the blocking of the hand position 211.
手位211以外针座21的轴线为中心对称设置，手位211可以为两个，沿外针座21的径向相对设置，该穿刺针在使用时，手术人员通过两个手位211，能够将所述穿刺针稳固持住，而且操作方便，手位211也可以为一个整体的圆饼结构，在推送该穿刺针时，能够更好的推压施力，更加安全的进行穿刺，且在准备穿刺手术前，由于手位211以外针座21的轴线为中心对称设置，因此可以稳固地放置在手术台上，不会轻易滚落。The axis of the outer needle holder 21 of the hand position 211 is arranged symmetrically. Two hand positions 211 can be arranged opposite to each other in the radial direction of the outer needle holder 21. When the puncture needle is in use, the operator can pass through the two hand positions 211. The puncture needle is held firmly and is easy to operate. The hand position 211 can also be an integral round cake structure. When the puncture needle is pushed, the puncture needle can be pushed better and the puncture can be performed more safely. Before preparing for the puncture operation, since the axis of the needle holder 21 outside the hand position 211 is symmetrically arranged at the center, it can be firmly placed on the operating table and will not easily roll off.
手位211为板状结构，且手位211与外针座21相互垂直，采用这样的设置，有利于手术人员握紧该穿刺针，避免手术人员在手术过程中滑落，而且手位211还可以根据实际需要或者手术人员的习惯制作为长方形板状、多边形板状等形状。The hand position 211 has a plate-shaped structure, and the hand position 211 and the outer needle seat 21 are perpendicular to each other. This arrangement helps the operator to hold the puncture needle tightly, avoiding the operator from slipping off during the operation, and the hand position 211 can also According to actual needs or the habit of the operator, it is made into a rectangular plate shape or a polygonal plate shape.
所述外针座为中空结构，该中空结构与所述外针的中空结构相贯通。The outer needle seat is a hollow structure, and the hollow structure is intersected with the hollow structure of the outer needle.
外针座21为中空结构，该中空结构与外针22的中空结构相贯通。外针22与外针座21的连接处设置有浮标3，且外针22贯穿浮标3，然后与外针座21连接。The outer needle seat 21 has a hollow structure, and the hollow structure is intersected with the hollow structure of the outer needle 22. A buoy 3 is provided at the connection between the outer needle 22 and the outer needle base 21, and the outer needle 22 penetrates the buoy 3 and then connects with the outer needle base 21.
外针22远离外针座21的一端得外壁上设置有刻线221，刻线221为螺旋线，且螺旋线交叉设置；刻线221还可以为平行设置的圆环线；当穿刺针在进行穿刺手术时，手术人员在手位的辅助下，持紧手位211并且用力将该穿刺针刺入人体，当穿刺针进入人体病灶附近时，探头转换器发出超声波，并照射在外针22的表面，尤其在螺旋线内，经过一定角度的反射使超声波信号可以更多的反射到探头转换器上，使超声影像设备显示的影像非常清晰，能够实时地监控到外针22到达的位置，此时可以进行甲状腺的取样、内针取出后的药物注射或者体液的引流抽吸等(注射或抽吸时无需再借助手位)；外针22远离外针座21的一端为针状结构的外针出口23，且螺旋线靠近外针出口23。采用这样的设置，由于超声波信号在螺旋线附近反射到探头转化器上的信号较多，这样外针出口23的穿刺情况就能够实时、清晰的显示在超声影像设备上，方便医护人员的判断以及下一步操作。The end of the outer needle 22 away from the outer needle seat 21 is provided with a score line 221 on the outer wall. The score line 221 is a spiral line, and the spiral lines are arranged crosswise; the score line 221 may also be a circular line arranged in parallel; when the puncture needle is in progress During the puncture operation, with the assistance of the hand position, the operator holds the hand position 211 firmly and pierces the puncture needle into the human body with force. When the puncture needle enters the human body near the lesion, the transducer of the probe emits ultrasonic waves and irradiates the surface of the outer needle 22 , Especially in the spiral line, after a certain angle of reflection, the ultrasonic signal can be more reflected to the probe converter, so that the image displayed by the ultrasonic imaging device is very clear, and the position of the outer needle 22 can be monitored in real time. It can be used for thyroid sampling, drug injection after the inner needle is taken out, or body fluid drainage and suction (no need to use the hand position when injecting or aspirating); the end of the outer needle 22 away from the outer needle seat 21 is an outer needle with a needle-like structure Exit 23, and the spiral is close to the outer needle exit 23. With this setting, because the ultrasonic signal reflects more signals on the probe converter near the spiral line, the puncture situation of the outer needle exit 23 can be displayed on the ultrasonic imaging equipment in real time and clearly, which is convenient for medical staff to judge and Next step.
外针组件2内套设有内针组件1；内针组件1包括内针座11以及位于内针座11一端的内针12；内针12远离内针座11的一端为内针出口13，且内针出口13为与外针出口23相同的针状结构，采用这样的设置方便医护人员进行穿刺或者注射。The outer needle assembly 2 is sheathed with an inner needle assembly 1; the inner needle assembly 1 includes an inner needle seat 11 and an inner needle 12 located at one end of the inner needle seat 11; the end of the inner needle 12 away from the inner needle seat 11 is an inner needle outlet 13, and In addition, the inner needle outlet 13 has the same needle-like structure as the outer needle outlet 23, and this arrangement is convenient for medical personnel to perform puncture or injection.
内针座11包括第二手持部以及位于第二手持部的一端的第二连接部111，第二连接部111内设置有内针12，内针12贯穿外针座21以及外针22，且内针座11与外针座21通过第二连接部111扣合在一起。The inner needle holder 11 includes a second holding part and a second connecting part 111 located at one end of the second holding part. An inner needle 12 is provided in the second connecting part 111, and the inner needle 12 penetrates the outer needle holder 21 and the outer needle 22. , And the inner needle holder 11 and the outer needle holder 21 are buckled together through the second connecting portion 111.
内针12的长度不小于外针22的长度，采用这样的设置有利于手术人员进行穿刺或者注射。The length of the inner needle 12 is not less than the length of the outer needle 22, and the adoption of such an arrangement is advantageous for the operator to perform puncture or injection.
具有手位的穿刺针，还包括保护套4，保护套4套设于外针22上，且与浮标3扣合在一起，保护套4可以用来保护该穿刺针，以免在不使用时，该穿刺针被污染。The puncture needle with hand position also includes a protective sleeve 4, which is sleeved on the outer needle 22 and is buckled together with the buoy 3. The protective sleeve 4 can be used to protect the puncture needle so as not to The puncture needle is contaminated.
本发明的具有手位的穿刺针，在使用时，首先取下保护套4，在超声影像设备的辅助下，一只手握住外针座21与内针座11连接处，手 指头往前施力推压手位211，使穿刺针刺入所需的位置后，另一只手捏住第二手持部拔出内针组件1，从而进行药物注射或者体液的引流步骤，因此具有易拿，易放，抓握方便，放置稳固等优点。另外当穿刺针进入人体病灶附近时，探头转换器发出超声波，并照射在外针22的表面，超声波在螺旋线内，经过一定角度的反射使超声波信号可以更多的反射到探头转换器上，使超声影像设备显示的影像非常清晰，能够实时地监控到外针22到达的位置，在穿刺针进入监控后，运动的实时性强，便于手术人员及时作出最佳的决策，大大提供了手术人员的方便性及手术的准确性，提高了手术的效率。The puncture needle with hand position of the present invention, when in use, first remove the protective cover 4, with the assistance of ultrasound imaging equipment, hold the connection between the outer needle holder 21 and the inner needle holder 11 with one hand, and move your fingers forward Push the hand position 211 with force to pierce the puncture needle into the desired position, and then pinch the second hand part with the other hand to pull out the inner needle assembly 1 to perform the drug injection or body fluid drainage step. It has the advantages of holding, easy to put, easy to grasp, stable and so on. In addition, when the puncture needle enters the vicinity of the human lesion, the transducer of the probe emits ultrasonic waves and irradiates the surface of the outer needle 22. The ultrasonic waves are reflected at a certain angle in the spiral line so that the ultrasonic signal can be more reflected to the transducer of the probe. The image displayed by the ultrasound imaging equipment is very clear, and it can monitor the position of the outer needle 22 in real time. After the puncture needle enters the monitoring, the movement is real-time, which is convenient for the surgeon to make the best decision in time, and greatly provides the surgeon with Convenience and accuracy of surgery improve the efficiency of surgery.
