Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a progressive puncture device for abdominal surgery. Background Art

[0002] In gastrointestinal surgery abdominal operations, the puncture operation is a crucial step, the purpose of which is to establish a surgical channel for subsequent operations. However, there are many drawbacks in the one-time puncture method adopted by traditional puncture devices.

[0003] In terms of puncture accuracy, when encountering patients with a relatively thick abdominal wall, it is very difficult to ensure accurate puncture to the target position with a one-time puncture. To achieve the goal, doctors may choose oblique puncture to form a subcutaneous tunnel. However, this method not only increases the complexity of puncture, but also may significantly increase the damage to the puncture point due to repeated punctures. For patients, this will undoubtedly increase their pain during the operation, and the postoperative recovery time will also be correspondingly prolonged.

[0004] In terms of the flexibility of surgical operation, the complex surgical environment poses higher requirements for the puncture device. Traditional one-time puncture is difficult to meet the need for multiple adjustments. In actual operation, it is difficult to accurately control the stability of the force when doctors puncture. Once the force is excessive when breaking through the abdominal wall, there will be a situation of sudden void, which will not only cause unnecessary damage to the surrounding tissues, but also greatly reduce the flexibility of surgical operation, making doctors have limited coping means in the face of complex situations.

[0005] In addition, traditional puncture devices have obvious deficiencies in protecting the surrounding tissues. During the puncture process, due to the lack of effective protection measures, the surrounding tissues are easily damaged, thus triggering a series of unnecessary complications, which pose potential risks to the postoperative recovery and physical health of patients.

[0006] In summary, the problems of traditional abdominal surgery puncture devices in terms of accuracy, flexibility, and protection of surrounding tissues seriously affect the quality of the operation and the prognosis of patients. Therefore, it is urgent to develop a more advanced and effective puncture device. Summary of the Invention

[0007] To overcome the existing problems, an embodiment of the present application provides a progressive puncture device for abdominal surgery. A threaded seat is designed on the upper surface of the fixator. The inside of the threaded seat is connected to the puncture assembly in a screwed manner. At the axis of the fixator where the threaded seat is located, a through hole is provided specifically for the smooth penetration of the puncture assembly. This threaded connection method enables the puncture assembly to drive itself to advance in a spiral manner through the interaction with the threaded seat when rotating. This progressive puncture method greatly reduces the degree of damage to the puncture point compared with traditional one-time puncture. Due to the reduction of puncture point damage, the postoperative recovery time of the patient is effectively shortened, reducing the pain and recovery cost of the patient.

[0008] The technical solution adopted by the embodiment of the present application to solve its technical problems is: A progressive puncture device for abdominal surgery, including a fixator. A puncture assembly penetrates through the inside of the fixator. The height of the puncture assembly is greater than the height of the fixator. A threaded seat is provided on the upper surface of the fixator. The threaded seat is a cylindrical structure. The threaded seat is a through-type structure. Internal threads are machined inside the threaded seat. The threaded seat and the fixator are of a fixed structure. The threaded seat is a cylindrical structure, and standard internal threads are machined inside it to adapt to the threads of the puncture assembly, ensuring the stability and accuracy of the puncture assembly when rotating forward. At the axis of the fixator, a through hole is opened. The diameter of the through hole is slightly larger than the outer diameter of the puncture assembly to ensure that the puncture assembly can pass through smoothly, and at the same time, a certain coaxiality can be ensured to keep the puncture needle perpendicular to the abdominal wall at all times; Among them, the puncture assembly is threadedly connected to the threaded seat. A bottom plate is provided at the bottom end of the fixator. The bottom plate is fixed on the surface of the abdominal wall. One end of the puncture assembly is passed through the fixator and screwed to the threaded seat. The puncture assembly is rotated. The puncture assembly advances progressively in a spiral manner inside the threaded seat to achieve puncture of the abdominal wall. The puncture needle end of the puncture assembly is passed through the through hole of the fixator and screwed to the threaded seat. The doctor holds and presses the pressing plate and rotates the pressing plate clockwise to drive the puncture needle to advance progressively in a spiral manner inside the threaded seat to achieve puncture of the abdominal wall.

[0009] Preferably, the puncture assembly includes a puncture needle connected to the threaded seat. The top end of the puncture needle is provided with a connection seat. The connection seat is of a hollow structure. A connecting pipe is provided on the side wall of the connection seat. One end of the connecting pipe is connected to an external pipeline. The intersection of the connecting pipe and the connection seat is a through structure. The top end of the connection seat is provided with a pressing plate. The pressing plate is connected to one end of the puncture needle. It adopts an ergonomic design, which is convenient for doctors to hold and operate. The surface of the pressing plate is provided with anti-slip textures to increase the friction force of the doctor during the operation and ensure the stability of the operation. The puncture assembly is mainly composed of a puncture needle and a pressing plate. The puncture needle is made of high-strength and corrosion-resistant medical stainless steel. Its needle tip has been specially polished, with good sharpness and toughness, which can not only ensure smooth penetration of the abdominal wall, but also avoid bending or breaking during the puncture process. The rod part of the puncture needle is processed with an external thread matching the internal thread of the threaded seat, and the length is designed according to different surgical requirements.

[0010] Preferably, the fixator is of a frustum structure. A through hole is opened inside the fixator. The size of the through hole is larger than the size of the puncture needle. The fixator and the bottom plate are of a concentric structure. A circular hole is opened at the axis of the bottom plate. The fixator is made of a medical-grade plastic material with certain toughness and strength. And the lower surface of the fixator is provided with a bottom plate to ensure that it can be stably fixed on the surface of the abdominal wall during the operation, and at the same time will not cause additional harm to the patient's abdominal wall. Its shape is designed as a disc shape, and the diameter of the disc can be optimized according to the common sizes of the human abdominal wall to ensure sufficient contact area and stability.

[0011] The advantages of the embodiments of the present application are: 1. The upper surface wall of the fixator is designed with a threaded seat. The inside of the threaded seat is connected to the puncture assembly by a screwing method. At the axis of the threaded seat where the fixator is located, a through hole is provided specifically for the puncture assembly to pass through smoothly.

This progressive puncture method greatly reduces the degree of damage to the puncture point compared with the traditional one-time puncture. Due to the reduction of the puncture point damage, the postoperative recovery time of the patient is effectively shortened, reducing the pain and recovery cost of the patient.

[0012] 2. The device is provided with a fixator, which can be firmly fixed on the surface of the abdominal wall. Its key role is to ensure that the puncture needle is perpendicular to the abdominal wall during puncture, which provides a basis for stable and accurate puncture. Through vertical puncture, it is possible to better protect the surrounding tissues and reduce the risk of complications caused by improper puncture angles, significantly improving the safety and success rate of the operation.

[0017] Embodiments of the present application provide a progressive puncture device for abdominal surgery to solve the problems in the prior art. A threaded seat is designed on the upper surface of the fixator. The internal part of the threaded seat is connected to the puncture assembly by a screwing connection. At the axis of the fixator where the threaded seat is located, a through hole is provided, which is specifically used for the puncture assembly to pass through smoothly. This threaded connection method enables the puncture assembly to drive itself to advance in a spiral manner through the interaction with the threaded seat when rotating. This progressive puncture method greatly reduces the degree of damage to the puncture point compared with traditional one-time puncture. Due to the reduction of puncture point damage, the postoperative recovery time of the patient is effectively shortened, reducing the pain and recovery cost of the patient. The device is provided with a fixator that can be firmly fixed on the abdominal wall surface. Its key role is to ensure that the puncture needle is perpendicular to the abdominal wall during puncture, which provides a basis for stable and accurate puncture. Through vertical puncture, the surrounding tissues can be better protected, and the risk of complications caused by improper puncture angle can be reduced, significantly improving the safety and success rate of the surgery.

[0018] The technical solutions in the embodiments of the present application are to solve the above problems, and the general idea is as follows: Embodiment 1 This embodiment gives the specific structure of a progressive puncture device for abdominal surgery, as Figures 1-6 shown, including a fixator 1. A puncture assembly 3 passes through the inside of the fixator 1. The height of the puncture assembly 3 is greater than the height of the fixator 1. A threaded seat 2 is provided on the upper surface of the fixator 1. The threaded seat 2 is a cylindrical structure. The threaded seat 2 is a through-type structure. Internal threads are machined inside the threaded seat 2. The threaded seat 2 and the fixator 1 are of a fixed structure. The threaded seat 2 is a cylindrical structure, and standard internal threads are machined inside it to fit the threads of the puncture assembly 3 to ensure the stability and accuracy of the puncture assembly 3 when rotating forward. At the axis of the fixator 1, a through hole 5 is opened. The diameter of the through hole 5 is slightly larger than the outer diameter of the puncture assembly 3 to ensure that the puncture assembly 3 can pass through smoothly, and at the same time, a certain coaxiality can be ensured so that the puncture needle 34 always remains perpendicular to the abdominal wall. Among them, the puncture assembly 3 is threadedly connected to the threaded seat 2. A bottom plate 4 is provided at the bottom end of the fixator 1. The bottom plate 4 is fixed on the abdominal wall surface. One end of the puncture assembly 3 passes through the fixator 1 and is screwed to the threaded seat 2. By rotating the puncture assembly 3, the puncture assembly 3 advances progressively in a spiral manner inside the threaded seat 2 to achieve puncture of the abdominal wall. One end of the puncture needle 34 of the puncture assembly 3 passes through the through hole 5 of the fixator 1 and is screwed to the threaded seat 2. The doctor holds the pressing plate 31 and rotates the pressing plate 31 clockwise to drive the puncture needle 34 to advance progressively in a spiral manner inside the threaded seat 2 to achieve puncture of the abdominal wall.

[0019] The puncture assembly 3 includes a puncture needle 34 connected to the threaded seat 2. A connection seat 32 is provided at the top end of the puncture needle 34. The connection seat 32 is of a hollow structure. A connecting pipe 33 is provided on the side wall of the connection seat 32. One end of the connecting pipe 33 is connected to an external pipeline. The intersection of the connecting pipe 33 and the connection seat 32 is a through structure. A pressing plate 31 is provided at the top end of the connection seat 32. The pressing plate 31 is connected to one end of the puncture needle 34 and is designed in line with ergonomics, facilitating the doctor's holding and operation. The surface of the pressing plate 31 is provided with anti-slip textures to increase the friction force during the doctor's operation and ensure the stability of the operation. The puncture assembly 3 is mainly composed of the puncture needle 34 and the pressing plate 31. The puncture needle 34 is made of high-strength and corrosion-resistant medical stainless steel. Its needle tip has been specially polished, having good sharpness and toughness, which can not only ensure smooth penetration of the abdominal wall but also avoid bending or breaking during the puncture process. The rod part of the puncture needle 34 is processed with an external thread matching the internal thread of the threaded seat 2, and its length is designed according to different surgical requirements.

[0020] The fixator 1 is of a frustum structure. A through hole 5 is opened inside the fixator 1. The size of the through hole 5 is larger than the size of the puncture needle 34. The fixator 1 and the bottom plate 4 are of the same concentric structure. A circular hole is opened at the axis center of the bottom plate 4. The fixator 1 is made of medical-grade plastic with a certain toughness and strength. And a bottom plate 4 is provided on the lower surface of the fixator 1 to ensure that it can be stably fixed on the surface of the abdominal wall during the operation without causing additional harm to the patient's abdominal wall. Its shape is designed as a disc, and the diameter of the disc can be optimized according to the common sizes of the human abdominal wall to ensure sufficient contact area and stability.

[0021] By adopting the above technical solutions: In a gastrointestinal surgical abdominal operation for gastric ulcer perforation, the surgeon selected this progressive puncture device.

[0022] The patient was overweight and had a thick abdominal wall. At the beginning of the operation, the nurse first took out the fixator 1 from the sterile package. The fixator 1 is made of medical-grade plastic and is in the shape of a disc. It is fixed at the predetermined puncture position on the patient's abdominal wall through the bottom plate 4 on the lower surface to ensure that the fixator 1 is closely attached to the abdominal wall and in a vertical state.

[0023] One end of the puncture needle 34 of the puncture assembly 3 was passed through the through hole 5 of the fixator 1 and screwed onto the threaded seat 2. The doctor held the pressing plate 31 by hand and rotated the pressing plate 31 clockwise, driving the puncture needle 34 to gradually advance in a spiral manner within the threaded seat 2 to achieve puncture of the abdominal wall.

[0024] As the puncture needle 34 advanced gradually in a spiral manner, the doctor could clearly feel the smoothness of the puncture process. Since the puncture needle 34 always remained perpendicular to the abdominal wall, it avoided the subcutaneous tunnel problem that might be brought about by oblique puncture and ensured the accuracy of the puncture.

[0025] Finally, the puncture was successfully completed with minimal damage to the puncture site. After the operation, the patient had less pain and the recovery speed was significantly accelerated. Compared with the patients using traditional puncture devices, the hospital stay was shortened.

[0026] During the actual surgical operation, first, the fixator 1 is fixed on the predetermined puncture position of the patient's abdominal wall through the bottom plate 4 on the lower surface to ensure that the fixator 1 is closely attached to the abdominal wall. Then, one end of the puncture needle 34 of the puncture assembly 3 passes through the through hole 5 of the fixator 1 and is screwed to the threaded seat 2. The doctor holds the pressing plate 31 by hand and rotates the pressing plate 31 clockwise to drive the puncture needle 34 to gradually advance in a spiral manner within the threaded seat 2 to achieve puncture of the abdominal wall. During the puncture process, the doctor can adjust the puncture speed and depth and finely adjust the puncture angle through the pressing plate 31 according to the actual situation of the operation to ensure the accuracy and safety of the puncture.

[0027] Finally, it should be noted that: Obviously, the above embodiments are merely examples for clearly illustrating the present invention and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
