Description

Technical Field

[0001] The utility model belongs to the technical field of multi-angle installation puncture devices, and particularly relates to a puncture device that can be installed and used at multiple angles. Background Art

[0002] A puncture device is a medical device designed to penetrate the skin or other body tissues for diagnostic or therapeutic purposes. It usually consists of a sharp needle-like structure and is sometimes used in combination with catheters, cannulas, or other medical devices to facilitate the extraction of body fluids (such as blood samples), the injection of drugs, the placement of drainage tubes, the performance of biopsies, or the creation of access to specific areas within the body (such as blood vessels, organs, or body cavities). There are various types of puncture devices, which may have different lengths, diameters, tip designs, and structures for auxiliary fixation or guidance according to different medical needs to ensure the performance, safety, and efficiency of the operation. In modern medicine, puncture operations are widely used in a variety of clinical scenarios, including intravenous puncture, lumbar puncture, thoracic puncture, central venous catheterization, etc.

[0003] Existing puncture devices require a fixing device. The problem with the above technology is that in modern medical practice, although the puncture device is an important tool in the field of minimally invasive surgery, its application during long and complex surgical procedures still faces a challenge: that is, the slight shaking phenomenon of the puncture device during continuous operation. This unexpected movement may not only affect the progress of the surgery, increase the risk of tissue damage, but also interfere with the operator's feel and fine control of the instrument, thus affecting the overall efficiency and safety of the surgery. Many current puncture device designs on the market often focus on the convenience of puncture and the establishment of the channel, but fail to fully consider how to effectively stabilize the puncture device throughout the surgery, especially during long and difficult surgical procedures, to prevent slight displacements caused by natural respiratory movements of the human body, vibrations during surgical operations, or the weight of the instrument itself. This oversight is undoubtedly a pity for the pursuit of extremely precise medical treatment. Summary of the Utility Model

[0004] Aiming at the problems existing in the prior art, the utility model provides a puncture device that can be installed and used at multiple angles and can overcome or at least partially solve the above problems.

[0005] The utility model is realized as follows: A puncture device that can be installed and used at multiple angles includes a mounting plate, a belt, a puncture device, and a box body. The upper end of the mounting plate is fixedly connected to the lower surface of the box body. The surface of the puncture device is slidably connected to the surface of the box body. Both ends of the belt are slidably connected to the upper surface of the mounting plate through chutes. A clamping device is arranged inside the box body, and an auxiliary mechanism is arranged at the upper end of the clamping device;

[0006] The clamping device is used to fix the puncture device;

[0007] The auxiliary mechanism is used to enhance the fixing effect of the puncture device.

[0008] In order to improve the usability and durability of the equipment, preferably, the clamping device includes a sliding groove, a movable block, a support rod, an elastic block and a clamping block, and the upper end of the box body is provided with two sliding grooves, the two sliding groove surfaces are slidably connected to the two movable block surfaces, the lower end of the movable block is slidably connected to the rear end surface of the clamping block, the rear ends of the two sides of the clamping block are fixedly connected to the surface of the elastic block, and the rear end of the movable block is slidably connected to the front end surface of the support rod. The puncturer can be adjusted to the most suitable angle for installation according to the specific needs of the box body surface, which meets the needs of diversified operation scenarios and improves the flexibility and practicality of the equipment. The limiting plate configured under the box body not only limits the movement range of the puncturer, but also guides it to go deep along a predetermined path to ensure the puncture process Precise positioning reduces operational errors and potential risks. The interactive design of the puncture device and the movable block, especially the linkage mechanism between the upper end of the movable block and the movable block, and the ramp structure at the lower end, work together on the clamping block to achieve intelligent clamping and dynamic adjustment of the puncture device. The thrust generated by the slope contact drives the clamping block to move smoothly along the support rod, and the friction pad set at the front end of the clamping block ensures the firmness and stability of the puncture device when fixed, prevents any unnecessary movement, and improves the reliability of the operation and the safety of the patient. After the puncture operation is completed, the integrated application of the elastic block demonstrates its function of returning to its original position, so that the clamping block can automatically rebound to its initial position after the puncture device is pulled out, without the need for manual intervention, simplifying the operating process, improving work efficiency, and maintaining the durability of the device.

[0009] In order to improve the accuracy of the device, preferably, the auxiliary mechanism includes a top block, a card block and a fixed groove, the lower surface of the puncture device is provided with a fixed groove, the surface of the fixed groove is in contact with the surface of the card block, the surface of one end of the card block is rotatably connected to the upper end of the movable block through a pin, and the rear end of the card block is in contact with the surface of the top block. As the puncture device gradually penetrates deeper, the card block is pushed up by the top block. This process not only prepares for the subsequent fixing operation, but also when the front end of the card block is finally accurately docked with the preset fixed groove on the surface of the puncture device, the puncture device is firmly locked, and through mutual engagement, it is ensured. It ensures the absolute stability of the puncture device during use, effectively prevents any slight displacement, and ensures the accuracy of the puncture path. It not only ensures the safety of the puncture operation, but also greatly improves the operational safety. The locking mechanism is simple and effective, which reduces the operating burden of medical staff and reduces the risk of accidental injury caused by movement of the puncture device, reflecting the high attention to patient safety. In the long-term use and maintenance needs, components such as the card block, top block and fixing groove are easy to inspect and clean, ensuring the sanitary conditions and long-term stable performance of the device, which is conducive to reducing medical costs and improving the overall utilization efficiency of medical resources.

[0010] To improve the stability of the device operation, preferably, the lower surface of the elastic block is fixedly connected to the inner surface of the box body, the upper surface of the support rod is fixedly connected to the lower inner surface of the movable block, the front surface of the clamping block contacts the surface of the puncture device. The tight fixed connection between the lower surface of the elastic block and the inner surface of the box body not only provides a basis for the entire puncture device fixing structure, but also utilizes the restoring force of the elastic block itself to ensure the automatic reset ability of the puncture device in the non-working state, increasing the durability and usability of the system. The fixed connection between the upper end of the support rod and the lower inner surface of the movable block constructs a stable guiding axis, enabling the movable block and its related moving components to smoothly operate on a predetermined trajectory, which is crucial for controlling the penetration path and depth of the puncture device, improving the accuracy and safety of the puncture operation. The design where the front surface of the clamping block directly contacts the surface of the puncture device, through a friction pad or other forms of contact surfaces, realizes the direct and effective fixation of the puncture device, ensuring that the puncture device remains stable during the puncture process. Even when a certain pressure is applied or during the operation process, it can maintain the puncture path unchanged, prevent deviation, thereby minimizing the operation risk to the greatest extent and protecting the patient's safety.

[0011] To simplify the operation process, preferably, the lower end of the top block is fixedly connected to the upper surface of the box body, and the lower end of the clamping block is slidably connected to the inner surface of the box body. By fixing the lower end of the top block to the upper surface of the box body, it ensures the firm immobility of the top block during the puncture device operation, providing a solid foundation for the guiding and fixing mechanism of the puncture device. This fixing method effectively avoids the displacement of the top block caused by external forces during the puncture operation, thereby improving the stability and durability of the entire system. The top block, as a key component interacting with the movable components during the penetration of the puncture device, the fixity of its position is crucial for guiding the puncture device to move along the expected path. Fixed to the upper end of the box body means that it can accurately participate in the propulsion control of the puncture device, helping the clamping block or related movable components to smoothly move on a predetermined trajectory, ensuring the puncture path. The design of the fixed connection simplifies the preparation work before the installation and operation of the puncture device. The user does not need to worry about the position adjustment of the top block, directly ensuring the consistency and reliability of each operation, improving the work efficiency, reducing the possibility of human errors, and being beneficial to the long-term use and maintenance of the equipment. It reduces the risk of equipment damage caused by component loosening or misalignment, extends the service life of the equipment, and reduces the maintenance cost.

[0012] To improve the positioning function, preferably, a limiting plate is provided on the lower surface inside the box body. The surface of the limiting plate is fixedly connected to the surface of the box body. Its design of being fixed to the box body surface plays a role in guiding the puncture device to move along the correct path. During the puncture process, the limiting plate acts like a guiding track, ensuring that the puncture device descends stably along the predetermined trajectory, improving the accuracy and repeatability of the puncture. By fixedly connecting the limiting plate to the box body surface, the structural stability of the entire device is enhanced, and it can effectively withstand the lateral force or longitudinal pressure that may be generated during the puncture process, avoiding operation errors caused by component movement, providing a solid support platform for the puncture operation. The fixed connection method simplifies the equipment assembly process, reduces the risk of component loosening, and is also convenient for daily inspection and maintenance. Once fixed in place, the position of the limiting plate is not easily changed, and it can still maintain the accuracy and reliability of its function after long-term use.

[0013] To improve the operating flexibility, preferably, the surface of the limiting plate is slidably connected to the surface of the puncture device. The lower surface of the puncture device contacts the upper surface of the box body, and the lower end of the puncture device contacts the upper end of the movable block. The surface of the limiting plate and the surface of the puncture device are connected in a sliding manner, allowing the puncture device to freely slide within a limited range, so as to adapt to different puncture depth requirements. The sliding connection ensures that during the puncture process, the puncture device can smoothly adjust its position and is restricted by the limiting plate to avoid over-puncturing, which not only ensures the operating flexibility. The design that the lower surface of the puncture device directly contacts the upper surface of the box body provides a stable support base point for the puncture device, ensuring the smoothness and reliability of the initial stage of the puncture action. This direct contact helps to disperse the force generated during the puncture, reduce vibration, and improve the operating stability.

The limit plate configured under the box body not only limits the moving range of the puncture device, but also guides it to penetrate along a predetermined path, ensuring the accurate positioning during the puncture process, reducing operation errors and potential risks.

The thrust generated by the slope contact drives the clamping block to move smoothly along the support rod, and the friction pad provided at the front end of the clamping block ensures the firmness and stability of the puncture device during fixation, preventing any unnecessary movement, improving the reliability of the operation and the safety of the patient.

When the front end of the clamping block finally accurately docks with the preset fixing groove on the surface of the puncture device, firm locking of the puncture device is achieved. Through mutual engagement, the absolute stability of the puncture device during use is ensured, effectively preventing any slight displacement and ensuring the accuracy of the puncture path. This not only ensures the effectiveness of the puncture operation, but also greatly improves the operation safety. The locking mechanism is simple and effective, reducing the operation burden of medical staff and the risk of accidental injury caused by the movement of the puncture device, reflecting the high attention to patient safety.

[0022] The structure of the present utility model will be described in detail below with reference to the accompanying drawings.

[0023] As Figures 1 to 4As shown in the figure, the puncture device provided by the embodiment of the present utility model that can be installed and used at multiple angles includes a mounting plate 4, a belt 5, a puncture device 6, and a box body 7. The upper end of the mounting plate 4 is fixedly connected to the lower surface of the box body 7. The surface of the puncture device 6 is slidably connected to the surface of the box body 7. Both ends of the belt 5 are slidably connected to the upper surface of the mounting plate 4 through sliding grooves. A clamping device 1 is arranged inside the box body 7, and an auxiliary mechanism 2 is arranged above the clamping device 1. The clamping device 1 is used to fix the puncture device 6, and the auxiliary mechanism 2 is used to enhance the fixing effect of the puncture device 6. The clamping device 1 includes a sliding groove 101, a movable block 102, a support rod 103, an elastic block 104, and a clamping block 105. Two sliding grooves 101 are opened at the upper end of the box body 7, and the surfaces of the two sliding grooves 101 are slidably connected to the surfaces of the two movable blocks 102. The lower end of the movable block 102 is slidably connected to the rear surface of the clamping block 105. Both sides of the rear end of the clamping block 105 are fixedly connected to the surface of the elastic block 104. The rear end of the movable block 102 is slidably connected to the front surface of the support rod 103. The puncture device 6 can be adjusted to the most suitable angle for installation according to the specific requirements on the surface of the box body 7, meeting the needs of diverse operation scenarios, and improving the flexibility and practicality of the device. The limiting plate 3 configured below the box body 7 not only limits the movement range of the puncture device 6 but also guides it to penetrate along a predetermined path, ensuring the precise positioning during the puncture process, reducing operation errors and potential risks. The interaction design between the puncture device 6 and the movable block 102, especially the linkage mechanism between the upper end of the movable block 102 and the movable block 102, and the slope structure at the lower end, jointly act on the clamping block 105 to achieve intelligent clamping and dynamic adjustment of the puncture device 6. The thrust generated by the slope contact drives the clamping block 105 to move smoothly along the support rod 103, and the friction pad provided at the front end of the clamping block 105 ensures the firmness and stability of the puncture device 6 during fixation, preventing any unnecessary movement, improving the reliability of the operation and the safety of the patient. After the puncture operation is completed, the integrated application of the elastic block 104 demonstrates its function of returning to the original position, enabling the clamping block 105 to automatically rebound to the initial position after the puncture device 6 is withdrawn without manual intervention, simplifying the operation process, improving work efficiency, and maintaining the durability of the device. The auxiliary mechanism 2 includes a top block 201, a clamping block 202, and a fixing groove 203. A fixing groove 203 is opened on the lower side surface of the puncture device 6, and the surface of the fixing groove 203 is in contact with the surface of the clamping block 202. One end surface of the clamping block 202 is rotatably connected to the upper end of the movable block 102 through a pin shaft, and the rear end of the clamping block 202 is in contact with the surface of the top block 201. As the puncture device 6 gradually penetrates, the clamping block 202 is pushed up by the top block 201. This process not only makes full preparations for the subsequent fixing operation. When the front end of the clamping block 202 is finally accurately docked with the preset fixing groove 203 on the surface of the puncture device 6, firm locking of the puncture device 6 is achieved. Through mutual engagement, the absolute stability of the puncture device 6 during use is ensured, effectively preventing any tiny displacement and ensuring the accuracy of the puncture path. It not only ensures the performance of the puncture operation but also greatly improves the operation safety.The locking mechanism is simple and effective, reducing the operation burden of medical staff and the risk of accidental injury caused by the movement of the trocar 6, reflecting a high degree of attention to patient safety. In terms of long-term use and maintenance requirements, components such as the clamping block 202, the top block 201, and the fixing groove 203 are easy to inspect and clean, ensuring the hygienic conditions and long-term stable performance of the device, which is conducive to reducing medical costs and improving the utilization efficiency of overall medical resources. The lower surface of the elastic block 104 is fixedly connected to the inner surface of the box body 7. The upper surface of the support rod 103 is fixedly connected to the lower inner surface of the movable block 102. The front surface of the clamping block 105 is in contact with the surface of the trocar 6. The lower surface of the elastic block 104 is tightly and fixedly connected to the inner surface of the box body 7, which not only provides a basis for the entire trocar 6 fixing structure but also utilizes the restoring force of the elastic block 104 itself to ensure the automatic reset ability of the trocar 6 in the non-working state, increasing the durability and usability of the system. The fixed connection between the upper end of the support rod 103 and the lower inner surface of the movable block 102 constructs a stable guiding axis, enabling the movable block 102 and its related moving components to move smoothly along a predetermined trajectory, which is crucial for controlling the insertion path and depth of the trocar 6, improving the accuracy and safety of the puncture operation. The design that the front surface of the clamping block 105 is directly in contact with the surface of the trocar 6 realizes the direct and effective fixation of the trocar 6 through a friction pad or other forms of contact surfaces, ensuring the stable immobility of the trocar 6 during the puncture process. Even under a certain pressure or during the operation, it can maintain the unchanged puncture path, prevent deviation, thereby minimizing the operation risk and protecting patient safety. The lower end of the top block 201 is fixedly connected to the upper surface of the box body 7, and the lower end of the clamping block 105 is slidably connected to the inner surface of the box body 7. By fixing the lower end of the top block 201 to the upper surface of the box body 7, it ensures the stable immobility of the top block 201 during the operation of the trocar 6, providing a solid foundation for the guiding and fixing mechanism of the trocar 6. This fixing method effectively avoids the displacement of the top block 201 caused by external forces during the puncture operation, thereby improving the stability and durability of the entire system. The top block 201, as a key component interacting with the moving parts during the insertion of the trocar 6, the fixity of its position is crucial for guiding the trocar 6 to move along the expected path. Fixed to the upper end of the box body 7 means that it can accurately participate in the advancement control of the trocar 6, helping the clamping block 202 or related moving components to move smoothly along a predetermined trajectory, ensuring the puncture path. The fixed connection design simplifies the preparation work before the installation and operation of the trocar 6. Users do not need to worry about the position adjustment of the top block 201, directly ensuring the consistency and reliability of each operation, improving work efficiency, reducing the possibility of human errors, and being beneficial to the long-term use and maintenance of the equipment. It reduces the risk of equipment damage caused by component loosening or misalignment, extends the service life of the equipment, and reduces the maintenance cost. A limiting plate 3 is arranged on the lower inner surface of the box body 7, and the surface of the limiting plate 3 is fixedly connected to the surface of the box body 7.Its design fixed on the surface of the box body 7 plays a role in guiding the puncture device 6 to move forward along the correct path. During the puncture process, the limiting plate 3 is like a guiding track, ensuring that the puncture device 6 steadily descends along the predetermined trajectory, improving the accuracy and repeatability of the puncture. By fixedly connecting the limiting plate 3 to the surface of the box body 7, the structural stability of the entire device is enhanced, and it can effectively withstand the lateral force or longitudinal pressure that may be generated during the puncture process, avoiding operation errors caused by component movement, and providing a solid support platform for the puncture operation. The way of fixed connection simplifies the assembly process of the device, reduces the risk of component loosening, and is also convenient for daily inspection and maintenance. Once fixed in place, the position of the limiting plate 3 is not easily changed, and it can still maintain the accuracy and reliability of its function after long-term use. The surface of the limiting plate 3 is slidably connected to the surface of the puncture device 6. The lower surface of the puncture device 6 contacts the upper surface of the box body 7, and the lower end of the puncture device 6 contacts the upper end of the movable block 102. The surface of the limiting plate 3 is slidably connected to the surface of the puncture device 6, allowing the puncture device 6 to freely slide within a limited range, so as to adapt to different puncture depth requirements. The sliding connection ensures that during the puncture process, the puncture device 6 can smoothly adjust its position and is restricted by the limiting plate 3 to avoid over-puncturing, which not only ensures the flexibility of the operation. The design that the lower surface of the puncture device 6 directly contacts the upper surface of the box body 7 provides a stable support base point for the puncture device 6, ensuring that the initial stage of the puncture action is stable and reliable. This direct contact helps to disperse the force generated during the puncture, reduce vibration, and improve the stability of the operation.,

[0024] The working principle of the present utility model:

[0025] During use, when selecting the specific installation position of the mounting plate 4, the specific puncture site needs to be considered. The fixing method between the waistband 5 and the adhesive tape can be selected for installation. When the installation of the box body 7 is completed, the puncture device 6 can be installed and guided to an appropriate position through the through hole opened at the upper end of the box body 7. During the process of gradually pushing the puncture device 6 deeper into the surface of the box body 7, the limiting plate 3 arranged under the box body 7 will guide the moving path of the puncture device 6. Then, the puncture device 6 will first contact the upper end of the movable block 102 arranged on the surface of the box body 7 and push the movable block 102 to move along the direction of the support rod 103. A slope is provided at the lower end of the movable block 102, and this slope will contact the slope at the rear end of the clamping block 105 and generate a driving force. At this time, the two clamping blocks 105 will simultaneously move towards the lower end of the puncture device 6, and the puncture device 6 will be fixed by the friction pads at the front ends of the clamping blocks 105 to ensure that it will not move during use. During the continuous downward movement of the puncture device 6, the clamping block 202 at the upper end of the movable block 102 will contact the top block 201 arranged at the rear end of the movable block 102 and lift the front end of the clamping block 202. This process will continue until the front end of the clamping block 202 contacts the fixing groove 203 opened on the surface of the puncture device 6 to further fix the puncture device 6, which can prevent unnecessary movement of the puncture device 6 during use and ensure the stability and accuracy of the puncture work. Once the puncture device 6 is fixed, the puncture work can begin. This process requires the operator to carry out according to specific operation specifications and steps to ensure the smooth progress of the puncture work. After the puncture operation is completed and the puncture device 6 is withdrawn, the clamping block 105 returns to its original position under the action of the elastic block 104 and waits for the next operation.
