Surgical puncture device

Abstract

The invention relates to the field of surgical medical technology, and discloses a surgical puncture device, comprising an injection mechanism, an infection prevention mechanism and a storage mechanism. The injection mechanism can prevent the injection direction of the needle from being changed, thereby avoiding damage to surrounding tissues, reducing the occurrence of infection and other complications, and improving the anesthesia effect. The infection prevention mechanism can effectively isolate the skin wound from bacteria, and detect the bleeding of the wound in real time. When the wound is infected and pus or other liquids flow out, it can be detected and a prompt can be given to remind the patient to prevent further deterioration of the disease. The storage mechanism can allow the patient with a retention tube on the back to control the wound in real time, so that effective treatment can be made in time when there is a problem with the wound. At the same time, when resting, it can avoid liquid reflux due to the small height difference between the storage bag and the chest cavity, reduce the infection probability, and can control the negative pressure of the storage bag and detect the storage situation in real time.

Description

Technical Field

[0001] The invention relates to the technical field of surgical medicine, in particular to a surgical puncture device. Background Art

[0002] Thoracentesis is a common medical procedure used to diagnose and treat abnormal accumulation of fluid in the chest cavity (pleural effusion). The procedure involves inserting a special needle into the chest and into the pleural cavity to extract fluid, thereby relieving pressure on the lungs and helping the patient improve their breathing function. Although thoracentesis is a relatively safe procedure, like all medical procedures, it also has certain risks and complications, such as infection, bleeding or lung damage.

[0003] In the actual operation, the patient usually sits on a chair with his back to the doctor, and the doctor manually anesthetizes the puncture site. During the operation in this way, the patient is in a movable state. When performing surgery on younger people or those with poor mental quality, the operation may fail due to the patient's movement, and in severe cases, it may lead to wound infection.

[0004] At the same time, during the anesthesia process for the patient, the syringe needs to be pulled out repeatedly, and the inside of the syringe needs to be observed to determine whether the blood vessel is punctured. However, the pulling of the needle by hand may cause the direction of the needle to change, which is not convenient for the subsequent implantation of the retention tube. The swinging of the needle may damage the surrounding tissues, including nerves, blood vessels and muscles, which may cause pain, bleeding, infection and other complications. The swinging of the needle may also affect the distribution of anesthetics in the local area, resulting in poor anesthetic effect, which may require additional anesthetics or re-injection.

[0005] In addition, when resting, the patient can only lie on his side due to the retention tube inside, but lying on his side may cause changes in chest pressure, resulting in discomfort or bleeding. However, lying flat can reduce chest pressure, which helps the healing of the puncture site and the patency of the retention tube. For this reason, we propose a surgical puncture device.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a surgical puncture device.

[0037] In a typical implementation of the present application, Figure 1-9 As shown, a surgical puncture device comprises:

[0038] The fixing mechanism 1 is used to improve the patient's treatment comfort and reduce the patient's treatment anxiety. The fixing mechanism 1 includes a comfort strap 6 worn on the patient. A treatment hole 7 is opened on the outside of the comfort strap 6. A fixing plate 8 is bonded to the inside of the treatment hole 7. The comfort strap 6 is similar in shape to a chest strap, which can visually reduce the medical environment and effectively reduce the patient's treatment anxiety. At the same time, the comfort strap 6 can also improve the comfort of the patient with the retention tube 29.

[0039] The injection mechanism 3 is used to perform anesthesia injection on the patient, and to detect the injection position quickly and smoothly during the anesthesia injection process to avoid anesthetic injection into the blood vessel, causing discomfort to the patient. The injection mechanism 3 includes an injection needle 10 installed on one side of the fixing plate 8, one side of the fixing plate 8 is fixedly connected to a support frame 9, the top of the support frame 9 is slidably connected to a syringe fixing frame 18, and the tube body of the injection needle 10 is slidably installed inside the syringe fixing frame 18. The injection mechanism 3 also includes a moving plate 13 slidably connected inside the support frame 9, the bottom of the syringe fixing frame 18 is fixedly connected to the top of the moving plate 13, both sides of the inner wall of the support frame 9 are provided with hidden grooves 11, both sides of the moving plate 13 are slidably connected to the inside of the corresponding hidden grooves 11, the inside of the moving plate 13 is slidably connected to a sliding plate 20, the top of the sliding plate 20 is fixedly connected to a piston fixing frame 19, and the piston of the injection needle 10 is slidably installed inside the piston fixing frame 19;

[0040] A moving motor 15 is fixedly installed inside the support frame 9, and the output end of the moving motor 15 extends to the top of the support frame 9. A moving drum 16 is fixedly connected to the output end of the support frame 9. A moving rope 17 is wound around the outside of the moving drum 16. One end of the moving rope 17 is fixedly connected to one side of the moving plate 13. One side of the inner wall of the two hidden grooves 11 is fixedly connected to a moving spring 14. One end of the two moving springs 14 is fixedly connected to one side of the moving plate 13. One side of the inner wall of the two hidden grooves 11 is provided with a moving tooth groove 12. The inside of the moving plate 13 is provided with a There are two driving grooves 21, and the insides of the two driving grooves 21 are rotatably connected with incomplete gears 23, and the two incomplete gears 23 are respectively meshed with the moving tooth grooves 12 close to the side of the piston fixing frame 19, and sliding tooth grooves 25 are opened on both sides of the sliding plate 20. The two incomplete gears 23 are respectively meshed with the sliding tooth grooves 25 close to the side of the sliding plate 20. One side of the sliding plate 20 is fixedly connected with two return tension springs 26, and one end of the two return tension springs 26 is fixedly connected with a damping plate 27, and the damping plate 27 is connected to the inside of the support frame 9 for damping sliding;

[0041] Through the above structure, anesthesia injection can be performed on the patient. Specifically, after the injection position is determined, the comfort band 6 is worn on the outside of the patient, and the treatment hole 7 is aligned with the injection position. After the comfort band 6 is worn, the injection needle 10 is placed on the top of the injection mechanism 3, the barrel of the injection needle 10 is inserted into the outside of the syringe fixing frame 18, and the piston of the injection needle 10 is inserted into the inside of the piston fixing frame 19. After the injection needle 10 is installed, the moving motor 15 is started, and the output end of the moving motor 15 rotates to drive the moving reel 16 to rotate, and the moving reel 16 rotates to move part of the The rope 17 is wound on the outside of the moving drum 16. In the process of the moving rope 17 being wound on the moving drum 16, the moving rope 17 gradually drives the moving plate 13 to move toward the injection position. The movement of the moving plate 13 drives the injection needle 10 to move toward the injection position, and the needle tip of the injection needle 10 is inserted into the skin. At the same time, the moving plate 13 slides inside the support frame 9 to drive the incomplete gear 23 to rotate. The rotation of the incomplete gear 23 drives the sliding plate 20 to slide inside the moving plate 13. The sliding of the sliding plate 20 drives the piston of the injection needle 10 to move, and the anesthetic inside the injection needle 10 is smoothly injected into the skin.

[0042] When the injection needle 10 slowly penetrates the skin, since the damping plate 27 is a damping connection inside the support frame 9, the movement of the sliding plate 20 will first stretch the return spring 26. When the tension of the return spring 26 is greater than the damping force of the damping plate 27 inside the support frame 9, the damping plate 27 slides inside the support frame 9. When the two incomplete gears 23 rotate to bring the missing teeth close to the sliding plate 20, the two incomplete gears 23 separate from the sliding plate 20, and the damping plate 27 stops sliding inside the support frame 9. The return spring 26 retracts, and the retraction of the return spring 26 drives the sliding plate 20 to move. The movement of the sliding plate 20 drives the piston fixing frame 19 to move. The movement of the piston fixing frame 19 drives the piston of the injection needle 10 to move in the opposite direction, so that the withdrawal action is completed, and it can be known whether the blood vessel is punctured.

[0043] Two driven grooves 22 are provided inside the movable plate 13, and driven gears 24 are rotatably connected inside the two driven grooves 22. The two driven gears 24 are respectively meshed with the movable tooth grooves 12 near the piston fixing frame 19, and the two driven gears 24 are respectively meshed with the adjacent incomplete gears 23. The movable plate 13 is rotatably connected inside with two power transmission shafts, and the two power transmission shafts are respectively meshed with the adjacent incomplete gears 23 and the driven gear 24.

[0044] Through the above structure, the sustainability of injection and withdrawal can be achieved. Specifically, during the movement of the injection needle 10, when the missing tooth part of the incomplete gear 23 is close to the moving tooth groove 12, the incomplete gear 23 is separated from the moving tooth groove 12, so that the sliding plate 20 cannot slide inside the moving plate 13. At this time, since the driven gear 24 is meshed with the moving tooth groove 12 and the power transmission shaft at the same time, the driven gear 24 rotates to drive the power transmission shaft to rotate, and the power transmission shaft rotates to drive the incomplete gear 23 to rotate, so that the incomplete gear 23 is meshed with the moving tooth groove 12 again, thereby driving the sliding plate 20 to slide inside the moving plate 13 again to inject the drug.

[0045] Furthermore, in the above scheme, since the injection mechanism 3 is fixed to the outside of the comfort strap 6, even if the patient is young or has poor mental quality and moves around, the injection position of the injection needle 10 will not be shifted, and the injection direction of the needle will be prevented from changing, thereby avoiding damage to surrounding tissues, reducing the occurrence of infection and other complications, and improving the anesthesia effect.

[0046] The anti-infection mechanism 4 is used for postoperative virus isolation and real-time detection of the wound. The anti-infection mechanism 4 includes a bacteria-isolating sheet 45 bonded to the inside of the treatment hole 7; the anti-infection mechanism 4 also includes a water immersion sensor 46 fixedly connected to the inside of the bacteria-isolating sheet 45, one side of the bacteria-isolating sheet 45 is fixedly connected to an anti-bacterial film 47, a detection end of the water immersion sensor 46 is fixedly connected to the inside of the anti-bacterial film 47, one side of the anti-bacterial film 47 is bonded to a bandage, and one side of the bacteria-isolating sheet 45 is fixedly installed with a first speaker 2, and the first speaker 2 is electrically connected to the water immersion sensor 46;

[0047] Through the above structure, effective antibacterial isolation can be carried out at the skin wound, and the bleeding situation of the wound can be detected in real time. Specifically, when the patient moves drastically or is carelessly bumped, it is easy to cause the wound to tear. If not handled in time, the chance of wound infection will increase. When the wound bleeds, the blood will soak the bandage. During the gradual soaking process, the detection end of the water immersion sensor 46 comes into contact with the blood. At this time, the first speaker 2 starts to emit a sound to remind the patient and medical staff that the wound is bleeding. It is worth mentioning that if the wound is infected and pus or other liquids flow out, it can be detected and a prompt can be given to prevent further deterioration of the condition.

[0048] The storage mechanism 5 is used to store the effusion and detect the storage status in real time. The storage mechanism 5 includes a storage shell 30 fixedly installed on the outside of the comfort bandage 6. The storage mechanism 5 also includes a retention tube 29 for drainage of pleural effusion. A color detection instrument 44 is fixedly installed on the outside of the comfort bandage 6. An electric hose clamp 43 is fixedly installed on the outside of the comfort bandage 6. The output end of the electric hose clamp 43 contacts the outside of the retention tube 29. The retention tube 29 is fixed on one side of the comfort bandage 6. A protective strip 28 is bonded to one side of the comfort bandage 6. The retention tube 29 is fixed by the opposite side of the comfort bandage 6 and the protective strip 28.

[0049] Through the above structure, effective antibacterial isolation can be performed at the skin wound, and the bleeding situation of the wound can be detected in real time. Specifically, when the patient moves drastically or bumps into something carelessly, it is easy for the output end of the retention tube 29 to slip out of the chest cavity, causing blood to flow out through the retention tube 29. When the blood flows out through the retention tube 29, it is detected by the color detection instrument 44, and the electric hose clamp 43 is started to clamp the retention tube 29 to avoid blood loss and liquid reflux to prevent infection.

[0050] The interior of the storage shell 30 is slidably connected to a negative pressure plate 32, and a driving motor 33 is fixedly installed on the bottom of the storage shell 30. The output end of the driving motor 33 is fixedly connected to a driving shaft 34, and a driving reel 35 is fixedly sleeved on the outside of the driving shaft 34. A driving rope 36 is wound around the outside of the driving reel 35, and one end of the driving rope 36 is fixedly connected to one side of the negative pressure plate 32. The interior of the storage shell 30 is divided into two chambers by the negative pressure plate 32. A storage bag 31 is placed in the left chamber of the storage shell 30, and the output end of the retention tube 29 is connected to the storage bag 31. An air pressure sensor 41 is fixedly connected to the top of the left chamber of the storage shell 30.

[0051] Through the above structure, the internal pressure difference of the storage bag 31 can be controlled to avoid secondary infection caused by liquid reflux, and at the same time, real-time feedback can be given to the situation of the storage bag 31. Specifically, the storage bag 31 is in an airless state before use. When resting, the patient can only lie on his side due to the retention tube 29 left inside. However, lying on his side may cause changes in chest pressure, resulting in discomfort or bleeding. However, lying flat can reduce chest pressure, which is conducive to the healing of the puncture site and the patency of the retention tube 29. However, when lying flat, the height difference between the storage bag 31 and the chest is small. , it is easy for liquid to reflux. At this time, the air pressure condition of the left chamber is detected in real time through the air pressure sensor 41. When it is detected that the air pressure in the left chamber is gradually increasing, the drive motor 33 is started at this time, and the output end of the drive motor 33 rotates to drive the drive shaft 34 to rotate. The rotation of the drive shaft 34 drives the drive reel 35 to rotate. The rotation of the drive reel 35 drives the drive rope 36 to be wound around the outside of the drive reel 35, and the negative pressure plate 32 is pulled to the side away from the storage bag 31, so that the air pressure in the left chamber is gradually reduced, thereby ensuring that the retention tube 29 is always in a drainage state.

[0052] A stopper tube 37 is fixedly connected to the top of the right chamber of the storage shell 30, one end of the stopper tube 37 extends to the outside of the storage shell 30, and the end of the stopper tube 37 extending to the outside of the storage shell 30 is connected to a stopper air ring 39, the inside of the stopper air ring 39 contacts the outside of the retention tube 29, and the other end of the stopper tube 37 is connected to a stopper air bag 38, which is fixedly connected to one side of the inner wall of the right chamber of the storage shell 30, and a stopper block 40 is fixedly connected to the left side of the negative pressure plate 32, and the stopper block 40 is adapted to the stopper air bag 38, and a second speaker 42 is fixedly installed on one side of the inner wall of the right chamber of the storage shell 30;

[0053] Through the above structure, the patient can be reminded when the storage bag 31 is full, and the flow of the retention tube 29 can be closed to prevent backflow. Specifically, when the storage bag 31 is full, the air pressure sensor 41 detects that the air pressure in the left chamber has increased, and starts the drive motor 33, driving the stop block 40 to gradually approach the stop air bag 38 and squeeze the stop air bag 38. The stop air bag 38 compresses the gas into the inside of the stop air ring 39 through the stop tube 37. At this time, the stop air ring 39 expands and presses the retention tube 29, so that the output end of the retention tube 29 is not connected to the input end, thereby preventing backflow. At the same time, after the drive motor 33 is started, the air pressure sensor 41 still detects that the air pressure in the left chamber is low. At this time, the second speaker 42 makes a sound to remind the patient.

[0054] It is worth mentioning that when the retention tube 29 is in a flow state, the air pressure in the left chamber of the storage shell 30 is always in a changing state. When the air pressure sensor 41 detects that the air pressure is in the current state for a long time, the retention tube 29 may be blocked. At this time, the second speaker 42 makes a sound to remind the patient.

[0055] The working principle of the present invention is as follows: after the injection position is determined, the comfort band 6 is worn on the outside of the patient, and the treatment hole 7 is aligned with the injection position, the injection needle 10 is placed on the top of the injection mechanism 3, the barrel of the injection needle 10 is inserted into the outside of the syringe fixing frame 18, and the piston of the injection needle 10 is inserted into the inside of the piston fixing frame 19, and the moving motor 15 is started, and the output end of the moving motor 15 rotates to drive the moving reel 16 to rotate, and the moving reel 16 rotates to roll part of the moving rope 17 on the outside of the moving reel 16, and in the process of the moving rope 17 being rolled on the moving reel 16, the moving rope 17 gradually drives the moving plate 13 to move toward the injection position, and the moving plate 13 moves to drive the injection needle 10 to move toward the injection position, and the needle head of the injection needle 10 is inserted into the skin, and at the same time, the moving plate 13 slides inside the support frame 9 to drive the incomplete gear 23 to rotate, and the incomplete gear 23 rotates to drive the sliding plate 20 to slide inside the moving plate 13, and the sliding of the sliding plate 20 drives the piston of the injection needle 10 to move, and the anesthetic inside the injection needle 10 is smoothly injected into the skin;

[0056] When the injection needle 10 slowly penetrates the skin, since the damping plate 27 is connected to the damping inside the support frame 9, the movement of the sliding plate 20 will first stretch the return tension spring 26. When the tension of the return tension spring 26 is greater than the damping force of the damping plate 27 inside the support frame 9, the damping plate 27 slides inside the support frame 9. When the two incomplete gears 23 rotate to bring the missing teeth closer to the sliding plate 20, the two incomplete gears 23 separate from the sliding plate 20, and the damping plate 27 stops sliding inside the support frame 9. The return tension spring 26 retracts, and the retraction of the return tension spring 26 drives the sliding plate 20 to move. The movement of the sliding plate 20 drives the piston fixing frame 19 to move. The movement of the piston fixing frame 19 drives the piston of the injection needle 10 to move in the opposite direction, so that the withdrawal action is completed, and it can be known whether the blood vessel is punctured.

[0057] After the operation is completed and the retention tube 29 is left, the patient's large-scale movement or careless bumping can easily cause the wound to tear. If not handled in time, the chance of wound infection will increase. When the wound bleeds, the blood soaks the bandage. During the gradual soaking process, the detection end of the water immersion sensor 46 contacts the blood. At this time, the first speaker 2 starts to emit a sound to remind the patient and medical staff that the wound is bleeding. It is worth mentioning that if the wound is infected and pus or other liquids flow out, it can be detected and a prompt can be given to prevent further deterioration of the condition.

[0058] When the patient moves greatly or bumps into something carelessly, causing the output end of the retention tube 29 to slip out of the chest cavity, blood flows out through the retention tube 29, and the blood is detected by the color detection instrument 44, and the electric hose clamp 43 is activated to clamp the retention tube 29 to prevent blood loss and liquid reflux, thereby preventing infection;

[0059] The supine posture can reduce the pressure on the chest, which is helpful for the healing of the puncture site and the patency of the retention tube 29. However, when lying flat, the height difference between the storage bag 31 and the chest cavity is small, which makes it easy for liquid to flow back. At this time, the air pressure condition of the left chamber is detected in real time by the air pressure sensor 41. When it is detected that the air pressure in the left chamber is gradually increasing, the drive motor 33 is started at this time, and the output end of the drive motor 33 rotates to drive the drive shaft 34 to rotate, and the drive shaft 34 rotates to drive the drive reel 35 to rotate, and the drive reel 35 rotates to drive the drive rope 36 wound around the outside of the drive reel 35, pulling the negative pressure plate 32 to the side away from the storage bag 31, so that the air pressure in the left chamber is gradually reduced, thereby ensuring that the retention tube 29 is always in a drainage state;

[0060] When the storage bag 31 is full, the air pressure sensor 41 detects that the air pressure in the left chamber has increased, and starts the drive motor 33, driving the stop block 40 to gradually approach the stop air bag 38 and squeeze the stop air bag 38. The stop air bag 38 compresses the gas into the interior of the stop air ring 39 through the stop tube 37. At this time, the stop air ring 39 expands and presses the retention tube 29, so that the output end of the retention tube 29 is not connected to the input end, thereby preventing backflow. At the same time, after starting the drive motor 33, the air pressure sensor 41 still detects that the air pressure in the left chamber is low. At this time, the second speaker 42 makes a sound to remind the patient.

[0061] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
