[0082] The mounting base 10 is adapted to be fixed to the side of the operating table.

[0083] The vertical support arm 20 is vertically disposed on the upper surface of the fixed base 10.

[0084] The sliding seat 21 is located on the inner side of the vertical support arm 20 and can be slidably adjusted along the height direction of the vertical support arm 20. The sliding seat 21 is provided with an insertion hole 211.

[0085] One end of the transverse support arm 30 is integrally formed with a downwardly extending rotating arm 31, which is inserted into the insertion hole 211 and can rotate around the axis of the insertion hole 211. The other end extends away from the vertical support arm 20. Preferably, a fixing screw for fixing the rotating arm 31 is provided on the side of the sliding seat 21.

[0086] One end of the guide member 40 is connected to the other end of the transverse support arm 30 and can be rotated and adjusted along the axis of the transverse support arm 30. A guide hole 44 is provided on the upper surface of the other end of the guide member 40 to facilitate the insertion of the tire reduction puncture needle. Advantageously, an annular spotlight can also be provided on the bottom surface of the guide member 40. The annular spotlight surrounds the guide hole 44 and emits an annular light ring to locate the puncture position.

[0087] Based on the above, by the sliding seat 21 on the vertical support arm 20 for height direction sliding adjustment, and the horizontal support arm 30 through the rotating arm 31 for rotating adjustment in the jack 211, the doctor can easily adjust the height and angle of the support according to the operation requirement, to ensure that the fetal reduction puncture needle can accurately reach the target position. This design greatly improves the flexibility of the operation and the adaptability to different operation conditions. The design of the guide 40 enables the fetal reduction puncture needle to be stably guided along its axis, reducing errors during the operation process and improving the accuracy and safety of the puncture. The setting of the guide hole 44 provides a clear channel for the puncture needle, which helps the doctor to maintain stable operation during the operation process, thereby improving the success rate of the operation. The entire support adopts a stable structure design, the fixing seat 10 can be fixed firmly on the side of the operating bed, and the vertical support arm 20 and the horizontal support arm 30 both have sufficient strength and stability, which can withstand various forces and moments during the operation process, to ensure the safe operation of the operation process. This fetal reduction needle puncture guide support provides an efficient, safe and reliable auxiliary tool for fetal reduction surgery through its flexible operability, accurate guidance, stable structure design and easy operation and maintenance, which helps to improve the success rate of the operation and the safety of the patient.

[0088] Preferably, in an embodiment of the utility model, the guide 40 includes a main body 41, a connecting part 42 and two guide parts 43.

[0089] The connecting part 42 is arranged on one side of the main body 41, the other end of the horizontal support arm 30 is provided with a connecting hole 32, one end of the connecting part 42 is arranged in the connecting hole 32 and can rotate along the axis of the connecting hole 32 and move adjustment along the depth direction of the connecting hole 32.

[0090] The two guide parts 43 are arranged on the other side of the main body 41 in an up-down opposite manner, and the guide hole 44 is arranged on each of the two guide parts 43.

[0091] In this way, the connecting part 42 can rotate along the axis in the connecting hole 32, and this adjustment function enables the guide 40 to be more accurately positioned to adapt to the requirements of different operation positions and angles. The doctor can fine-tune the position and angle of the guide 40 according to the actual situation of the operation, thereby further improving the accuracy and safety of the operation.

[0092] And the other side of the main body 41 is provided with two guide parts 43 in an up-down opposite manner, and the guide hole 44 is arranged on each of the two guide parts 43. This design not only provides more selection paths for the fetal reduction puncture needle, but also enhances the stability of the guide. When the puncture needle punctures through one of the guide holes 44, the other guide hole 44 can serve as an auxiliary support to reduce the shaking and deviation during the puncture process, ensuring the smooth progress of the puncture.

[0093] As preferred, in another embodiment of the utility model, one side of two the guide portion 43 can set fixed screw still, fixed screw end portion can extend to the guide hole 44 in, to the puncture needle that wears in the guide hole 44 is fixed, in order to facilitate the injection of subsequent medicine.

[0094] Preferred, in an embodiment of the utility model, the outer surface of the connecting portion 42 is equipped with first protruding portion 421, the first protruding portion 421 extends along the circumference of the connecting portion 42, the outer surface of the first protruding portion 421 is equipped with a plurality of locking portions 422 along its circumference;

[0095] The inner wall of the connecting hole 32 is equipped with second protruding portion 321, the second protruding portion 321 extends along the circumference of the connecting hole 32, the inner surface of the second protruding portion 321 is equipped with a plurality of locking grooves 322 along its circumference, the first protruding portion 421 is inserted into the second protruding portion 321, and one end of each of the first locking portions 422 is inserted into the locking groove 322 opposite to each other;

[0096] Among them, the length of the locking groove 322 is less than the length of the locking portion 422.

[0097] It can be understood that, since the connecting portion 42 can not only rotate along the axis in the connecting hole 32, but also move and adjust along the depth direction of the connecting hole 32, and the length of the locking groove 322 is less than the length of the locking portion 422, when the connecting portion 42 moves outward, the locking portion 422 will move out of the locking groove 322, at this time, the connecting portion 42 can be rotated.

[0098] In this way, through the cooperation of the first protruding portion 421 and the second protruding portion 321, and the insertion of the locking portion 422 and the locking groove 322, a stable connection and locking mechanism is formed. This design not only ensures the stability of the connecting portion 42 in the connecting hole 32, but also prevents the accidental loosening or rotation of the connecting portion 42 during the operation, thereby ensuring the smooth progress of the operation. Because the guide 40 has high adjustment accuracy and flexibility, and the stability of the double guide hole 44 design, the support can be applied to more types of fetal reduction surgery.

[0100] Therefore, the third protruding portion 323 provides an additional limiting point for the first protruding portion 421. When the first protruding portion 421 is inserted into the connecting hole 32 and rotated to the locking position, the third protruding portion 323 can prevent the first protruding portion 421 from accidentally coming out of the connecting hole 32. This design not only enhances the stability of the connection, but also improves the reliability of the entire bracket structure.

[0101] Preferably, in an embodiment of the utility model, the connecting portion 42 surface is equipped with reset spring 45, reset spring 45 is located between the first protrusion and the third protrusion.

[0102] Therefore, when the connecting portion 42 moves outward, the locking portion 422 moves out of the locking groove 322 to adjust the rotation of the connecting portion 42. At this time, the reset spring 45 is in a compressed state. When the adjustment is completed, the tension on the connecting portion 42 is released. At this time, the elastic force of the reset spring 45 can drive the connecting portion 42 to reset, so that the locking portion 422 reenters the locking groove 322, thereby completing the automatic locking of the connecting portion 42. The adjustment method is simple and convenient, saving time and effort.

[0103] Preferably, in an embodiment of the utility model, the upper surface of the connecting portion 42 is provided with an indicator line 423, and the outer surface of the other end of the transverse support arm 30 is provided with a plurality of scale lines 33.

[0104] Therefore, the presence of the scale line 33 provides a visual reference for the doctor, allowing the doctor to more accurately control the rotation angle of the connecting portion 42. During the operation, the doctor can determine the current position and target position of the connecting portion 42 by reading the scale line 33 as needed, thereby achieving more accurate adjustment. The design of the degree line simplifies the operation process. The doctor does not need to rely on additional measuring tools or equipment to determine the rotation angle of the connecting portion 42, but can directly complete the adjustment by reading the scale line 33. This not only saves operation time, but also improves the efficiency and accuracy of the operation.

[0105] Preferably, in an embodiment of the utility model, the transverse support arm 30 includes a sleeve portion 34, a telescopic portion 35, and a first locking screw 36.
