Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a thoracic puncture guiding and positioning device for respiratory medicine. Background Art

[0002] Thoracentesis is a common diagnostic and treatment method in respiratory medicine. For example, pleural effusion is extracted for testing to identify the cause, or decompression treatment is performed for diseases such as pneumothorax. However, traditional thoracentesis has many shortcomings in positioning.

[0003] Traditional thoracentesis mainly relies on the doctor's experience and physical examination to determine the puncture point, such as determining the solid sound boundary through percussion and auscultating changes in breath sounds, but these methods are highly subjective and have limited accuracy. During the puncture process, it is difficult for doctors to accurately grasp the depth, angle and direction of the needle, which can easily lead to puncture failure, such as mistakenly puncturing blood vessels, nerves or other important tissues, causing complications such as bleeding, aggravated pneumothorax, and nerve damage. In addition, for some obese patients, patients with abnormal chest structure, or patients with a small amount of pleural effusion and uneven distribution, accurate positioning is even more difficult and may require multiple puncture attempts, which not only increases the patient's pain, but also prolongs the operation time and increases the risk of infection.

[0004] With the continuous development of medical technology, auxiliary positioning methods and equipment have emerged. It is possible to know the puncture point, puncture depth and puncture angle in the early stage of puncture, accurately locate the puncture point, and ensure that the puncture needle penetrates at a fixed angle and a fixed depth at the puncture point. This has become a major requirement for the positioning device. The existing positioning device is mainly for vertical puncture. Through preliminary preparation, only the distance between the chest cavity and the skin surface can be known. The depth of puncture needle penetration can reflect the puncture position, but when puncturing at a certain puncture angle, the penetration depth must be appropriately increased according to the puncture angle to reach the preset position, which increases the workload. At the same time, because the puncture needle is relatively slender and comes in many sizes, it is difficult to make a protective device for the puncture needle. When performing the needle, the needle must still rely on the hand of the needle performer at the puncture point as an aid to support the needle to enter the human body smoothly, which is complicated to operate. Summary of the invention

[0005] The present invention is intended to provide a thoracic puncture guiding and positioning device for respiratory medicine, so as to solve the problems of inaccurate positioning, complicated operation and uncontrollable puncture depth when there is an angle in the existing thoracic puncture.

DETAILED DESCRIPTION

[0022] The present invention is further described in detail below with reference to the accompanying drawings and embodiments:

[0023] Embodiment 1:

[0024] like Figure 1-5 A thoracic puncture guiding and positioning device for respiratory department shown in the figure comprises a positioning mechanism and a supporting mechanism, wherein the positioning mechanism comprises a positioning block 1, a channel tube 2 is arranged at the front end of the positioning block 1, a rotating device 3 is connected to the side wall of the bottom end of the channel tube 2, the rotating device 3 can control the rotation of the channel tube 2, the rotating device 3 comprises a rotating wheel 18, a rotating rod 19 is fixedly connected to the bottom end of the rotating wheel 18, a gear 1 20 is fixedly connected to the side wall of the rotating rod, the gear 1 20 is meshed with a gear 2 21, the gear 2 21 is fixedly connected to a rotating rod 2 22, the rotating rod 2 22 is fixedly connected to the channel tube 2, the gear 1 20 has less teeth than the gear 2 21, and one circle rotation of the rotating wheel 18 will cause the channel tube 2 to rotate a smaller angle, which is directly related to the gear ratio of the two gears. The rotating wheel 18 is marked with scales corresponding to the rotation angle of the channel tube 2, so that the operator can accurately control the rotation angle of the channel tube 2, and then accurately control the insertion angle of the puncture needle, thereby improving the accuracy and safety of the puncture.

[0025] The top of the positioning block 1 is fixedly connected with a depth control device 4 and a plurality of support columns 5, and the tops of the plurality of support columns 5 are fixedly connected with a fixing plate 6, and the top of the fixing plate 6 is connected to a supporting mechanism, and the supporting mechanism includes a fixing device 7 and a connecting column 8, and the fixing device 7 can be clamped on a bed board or directly stand on the ground, and the fixing device 7 includes a base plate, and the bottom end of the base plate is fixedly connected with an anti-sliding block 12 or a pulley block. During the operation, the patient usually needs to lie flat on the bed for frontal puncture, or lie on the table for back puncture. The device can be placed directly in a fixed position to meet most surgical needs. When puncture is required at different positions, the device can be easily moved by a pulley block to adapt to dynamic changes during the operation and ensure the flexibility and convenience of the operation.

[0026] A support rod 9 is arranged at the top of the fixing device 7, and a rotating block 10 is rotatably connected to the top of the support rod 9, and a sliding rod 11 is fixedly connected to the side wall of the rotating block 10, and a sliding block 12 is arranged on the outer sleeve of the sliding block 11, and a threaded hole is opened on the side wall of the sliding block 12, and a threaded pin is threadedly connected to the threaded hole, and a telescopic rod 13 is fixedly connected to the bottom end of the sliding block 12, and a rotating ball 14 and a rotating ball 2 15 are respectively fixedly connected to the two ends of the connecting column 8, and a rotating ball 14 and a rotating ball 2 15 are respectively sleeved with a rotating ball shell 16 and a rotating ball shell 2 17 on the outside of the rotating ball 14 and the rotating ball 2 15, and the rotating ball shell 16 and the rotating ball shell 2 17 are respectively fixedly connected to the fixing plate 6 and the telescopic rod 13. By operating the telescopic rod 13 and rotating the two rotating balls, the position of the device can be quickly adjusted to accurately align with the preset puncture point, thereby saving precious positioning time and improving the efficiency of the operation. This design enables the device to be flexibly adjusted to the required puncture position, ensuring the accuracy and convenience of the operation.

[0027] The depth control device 4 includes a column 23 and a marking block 24. A chute 25 is provided at the front end of the column 23. The marking block 24 and the chute 25 are slidably connected. A compression spring 1 26 is provided between the top of the marking block 24 and the top of the chute 25. A telescopic rod 27 is fixedly connected to the front end of the marking block 24. A spring clip 28 is fixedly connected to the free end of the telescopic rod 27. The telescopic rod 27 is a spring telescopic rod. There is a scale on the column 23. After the marking block 24 is pulled to the depth required for puncture, the spring clip 28 is pulled to make the telescopic rod 27 extend and retract, so that the spring clip 28 clamps the needle tube. When the marking block 24 reaches the bottom of the chute 25, the depth required for puncture is reached. During operation, the user can pull the marking block 24 to the required puncture depth, and then pull the spring clip 28 to make the telescopic rod extend and retract, thereby clamping the needle tube to ensure accurate control of the puncture depth. When the marking block 24 moves to the bottom of the chute 25, it means that the predetermined puncture depth has been reached. This design makes depth control both intuitive and accurate, allowing medical staff to quickly set and adjust the puncture depth, thereby improving the accuracy and safety of the operation.

[0028] Several ball groups are longitudinally arranged inside the channel tube 2, and the ball groups include four metal balls 29 abutting against each other. The channel tube 2 is provided with movable grooves 30 at positions corresponding to the metal balls 29, and a compression spring 31 is arranged between the metal balls 29 and the bottom ends of the movable grooves 30. When the puncture needle is inserted into the channel tube 2, it will pass through the gap formed by the metal balls 29. These metal balls 29 apply uniform pressure around the puncture needle, which helps to keep the puncture needle in shape during the process of piercing human tissue and prevent bending or deformation due to uneven force. In addition, the gap between the metal balls 29 can be adaptively adjusted according to the diameter of the puncture needle to ensure that the puncture needle can pass through the channel tube 2 smoothly, while reducing damage to the needle body and improving the accuracy and safety of the puncture. This design enables the device to adapt to puncture needles of different specifications, increasing its flexibility and wide application.

[0029] The bottom end of the positioning block 1 is equipped with a cushion pad, which is designed to adapt to the skin contours of different parts of different patients' bodies, ensuring additional comfort for patients during the puncture process. In addition, the presence of the cushion pad also helps to reduce the discomfort or pressure points that may occur during the puncture process, further improving the patient's experience.

[0030] In order to ensure the stability of the device during operation, locking mechanisms are provided between the rotating wheel 18, the telescopic rod 13, the rotating ball 14 and the rotating ball shell 16, and the rotating ball 2 15 and the rotating ball shell 2 17. These locking mechanisms may have high impedance characteristics, which can ensure that the various components of the device remain in a fixed position without movement or offset without human intervention. This design not only improves the safety during the operation, but also ensures the accuracy and reliability of the puncture operation. Through these locking devices, medical staff can operate with confidence during the operation without worrying about potential risks or errors caused by the movement of the device.

[0031] Embodiment 2:

[0032] The fixing device 7 includes a splint, and an efficient locking mechanism is installed at the bottom end of the splint, which can firmly lock the splint in the corresponding position of the bed, ensuring the stability and safety of the device when performing the frontal puncture operation. This design takes into account the space utilization and the convenience of operation, so that when the patient lies flat on the bed, the device can be compactly placed, thereby reducing the occupation of the surrounding space and providing a more spacious operating area for medical staff. Such a layout not only improves the efficiency of the operation, but also allows medical staff to be more flexible and convenient when performing the puncture operation.

[0033] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical solutions or characteristics in the solution is not described in detail here. For those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
