Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a puncture positioning device for interventional surgery. Background Technology

[0002] With the rapid development of medical technology, interventional surgery, as a minimally invasive treatment method, has been widely used in clinical medicine due to its advantages such as minimal trauma, rapid recovery, and significant efficacy. Interventional surgery typically involves diagnosing and treating lesions within the body through the skin, blood vessels, or other natural cavities using instruments such as catheters and guidewires. To ensure the accuracy and safety of the procedure, puncture localization technology has become a crucial aspect of interventional surgery.

[0003] However, traditional puncture localization mainly relies on the doctor's experience and feel, using surface landmarks, imaging data, and the tactile sensation of surgical instruments to determine the puncture point and path. This method is highly subjective and uncertain. During puncture, the doctor needs to support the puncture needle assembly with both hands, making it susceptible to various factors such as the doctor's experience, individual patient differences, and the surgical environment, which can cause shaking, leading to puncture errors and surgical risks, and causing considerable trouble for interventional procedures. Therefore, the applicant proposes a puncture localization device for interventional surgery to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a puncture positioning device for interventional surgery, which aims to improve the problems of traditional puncture positioning methods, which have great subjectivity and uncertainty, and are easily affected by various factors such as doctor's experience, individual patient differences and surgical environment, resulting in shaking, thus causing puncture errors and surgical risks.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A puncture positioning device for interventional surgery, comprising:

[0007] A positioning mechanism and an operating mechanism assembled at the front end of the positioning mechanism;

[0008] The positioning mechanism includes an arc-shaped positioning frame, a positioning sleeve is slidably installed on the periphery of the arc-shaped positioning frame, and symmetrically distributed suction cups are hinged to the bottom of the arc-shaped positioning frame.

[0009] The operating mechanism includes a fixed box fixedly installed at the front end of the positioning sleeve. A threaded seat is slidably installed inside the fixed box. A clamping ring is hinged to the front end of the threaded seat. The clamping ring is located at the front end of the fixed box. A puncture needle is clamped and fixed between the clamping rings. Operating arms are connected to both sides of the clamping rings.

[0010] Preferably, the top surface of the arc-shaped positioning frame is engraved with scale lines, and the top of the positioning sleeve is provided with positioning holes corresponding to the scale lines.

[0011] Preferably, a fixing bolt is threaded onto the rear end of the positioning sleeve, and the threaded end of the fixing bolt penetrates the positioning sleeve and abuts against the rear end surface of the arc-shaped positioning frame.

[0012] Preferably, a threaded rod that passes through the threaded seat is rotatably mounted inside the fixing box, and a turntable extending out of the fixing box is fixedly mounted on the top of the threaded rod.

[0013] Preferably, the threaded seat and the clamping ring are hinged together by a hinge seat, and the front end of the fixing box is provided with a sliding opening for the hinge seat to move.

[0014] Preferably, the inner wall of the clamping ring is covered with an anti-slip pad, which is made of rubber material.

[0015] Preferably, a pressing seat is fixedly installed at the rear end of the operating arm, and a thrust spring is fixedly connected between the operating arms.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] (1) The present invention is equipped with a positioning mechanism and an operating mechanism that work together to attach the arc-shaped positioning frame to the appropriate position on the patient's body according to the puncture position. The arc shape of the arc-shaped positioning frame makes it easy to accurately position the puncture needle to the appropriate puncture angle. The operating mechanism can easily drive the puncture needle to perform slow puncture, and can control the puncture speed more accurately. It can perform single-hand puncture operation without the need to support the puncture needle. It is less likely to shake during puncture, reducing the error during puncture and bringing more convenience to interventional surgery.

[0018] (2) By providing a clamping ring, this utility model can use the pressing seat to make the operating arm drive the clamping ring to open and close, which can quickly fix the puncture needle and facilitate the replacement of the puncture needle. Attached Figure Description

[0029] Example 1:

[0030] Please see Figure 1 , Figure 2, Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a puncture positioning device for interventional surgery includes:

[0031] Positioning mechanism 1 and operating mechanism 2 assembled at the front end of positioning mechanism 1;

[0032] The positioning mechanism 1 includes an arc-shaped positioning frame 11, a positioning sleeve 12 is slidably installed on the periphery of the arc-shaped positioning frame 11, and suction cups 16 arranged symmetrically are hinged to the bottom of the arc-shaped positioning frame 11.

[0033] The operating mechanism 2 includes a fixed box 21 fixedly installed at the front end of the positioning sleeve 12. A threaded seat 28 is slidably installed inside the fixed box 21. A clamping ring 22 is hinged to the front end of the threaded seat 28. The clamping ring 22 is located at the front end of the fixed box 21. A puncture needle 3 is clamped and fixed between the clamping rings 22. Operating arms 23 are connected to both sides of the clamping rings 22.

[0034] As can be seen from the above, during use, depending on the puncture location, the suction cup 16 can be used to easily attach the arc-shaped positioning frame 11 to the appropriate position on the patient's body. By pressing the operating arm 23 to close it, the clamping ring 22 can be easily opened, allowing the puncture needle 3 to be easily placed between the clamping rings 22. The clamping ring 22 can quickly clamp and fix the puncture needle 3. By driving the positioning sleeve 12 to slide along the arc-shaped positioning frame 11, the entire operating mechanism 2 can be easily rotated, allowing the puncture needle 3 to be easily adjusted to the appropriate puncture angle. By fixing the positioning sleeve 12 in the appropriate position, the puncture needle 3 can be easily positioned to the required puncture angle.

[0035] By driving the threaded seat 28 to slide up and down along the inside of the fixed box 21, the clamping ring 22 can be easily moved up and down, which can easily drive the puncture needle 3 to the puncture site on the patient. It can support the puncture needle 3 during puncture, and can be performed with one hand without the need to support the puncture needle 3 with the hand. It is less likely to shake during puncture, which brings more convenience to interventional surgery.

[0036] Depend on Figure 3 It can be seen that the top surface of the arc-shaped positioning frame 11 is engraved with scale lines 15, and the top of the positioning sleeve 12 is provided with positioning holes 14 corresponding to the scale lines 15.

[0037] As can be seen from the above, when the positioning sleeve 12 slides along the arc-shaped positioning frame 11, the positioning sleeve 12 can be slid to the designated position with relatively high accuracy by observing the value on the scale line 15 corresponding to the positioning hole 14, which facilitates the positioning operation of the puncture angle.

[0038] For details, please refer toFigure 3 As shown, a fixing bolt 13 is threadedly installed at the rear end of the positioning sleeve 12, and the threaded end of the fixing bolt 13 penetrates the positioning sleeve 12 and abuts against the rear end surface of the arc-shaped positioning frame 11.

[0039] As can be seen from the above, by rotating the fixing bolt 13, the positioning sleeve 12 can be easily moved to a suitable position and fixed, thus preventing the positioning sleeve 12 from accidentally sliding.

[0040] For details, please refer to Figure 5 As shown, a threaded rod 27 that passes through a threaded seat 28 is rotatably mounted inside the fixed box 21, and a turntable 29 that extends out of the fixed box 21 is fixedly mounted on the top of the threaded rod 27.

[0041] As can be seen from the above, the rotation of the threaded rod 27 can be easily operated by using the turntable 29. The threaded rod 27 and the threaded seat 28 are connected by a thread. The rotation of the threaded rod 27 can drive the threaded seat 28 to move up and down, which can conveniently and accurately control the puncture speed and facilitate the slow puncture operation of the puncture needle 3.

[0042] Example 2:

[0043] refer to Figure 5 and Figure 6 As shown, the threaded seat 28 and the clamping ring 22 are hinged together by a hinge seat 211, and the front end of the fixed box 21 has a sliding opening 210 for the hinge seat 211 to move.

[0044] As can be seen from the above, the hinge seat 211 allows the clamping ring 22 to open and close, which facilitates the clamping operation of the puncture needle 3. The sliding mouth 210 allows the threaded seat 28 to move up and down, which can drive the hinge seat 211 to slide up and down along the sliding mouth 210, thus preventing the hinge seat 211 from shaking.

[0045] refer to Figure 5 and Figure 6 As shown, an anti-slip pad 26 is attached to the inner wall of the clamping ring 22. The anti-slip pad 26 is made of rubber material.

[0046] As can be seen from the above, when the puncture needle 3 is clamped by the clamping ring 22, the anti-slip pad 26 can be used to increase the friction between the clamping ring 22 and the puncture needle 3, making it less likely for the puncture needle 3 to slip or fall off, thus improving the stability of the puncture.

[0047] refer to Figure 4 As shown, a pressing seat 24 is fixedly installed at the rear end of the operating arm 23, and a thrust spring 25 is fixedly connected between the operating arms 23.

[0048] As can be seen from the above, by pressing the pressing seat 24 with a finger, the clamping ring 22 can be opened by the operating arm 23. When the pressing seat 24 is released, the clamping ring 22 can be closed by the pushing force applied to the operating arm 23 by the thrust spring 25, which can conveniently and quickly clamp and fix the puncture needle 3.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
