[0002] Lung puncture is a common medical procedure widely used in the diagnosis and treatment of lung diseases. Usually, lung puncture is used to obtain lung tissue or fluid samples for pathological examination or bacterial culture. In addition, lung puncture is also often used for therapeutic purposes, such as draining pleural effusion or pneumothorax.

[0003] Existing puncture fixing frames are usually only used to fix puncture needles and ultrasonic probes. When draining effusion through lung puncture technology, the puncture needle first pierces the patient's skin tissue, and then the drainage tube is inserted into the chest cavity through the inner cavity of the puncture needle to ensure that the end of the drainage tube reaches the effusion area. The angle of the puncture needle needs to avoid important anatomical structures, such as blood vessels, nerves and lung tissues, to reduce the risk of accidental injury. Existing puncture fixing frames are difficult to adapt to the multi-angle insertion requirements of the puncture needle, and during the drainage process, it is difficult to fix the position of the drainage tube, which may cause the drainage tube to shift, thereby affecting the drainage effect.

DETAILED DESCRIPTION

[0017] 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.

[0018] See also Figures 1 to 9 The present invention provides a technical solution: a lung puncture fixing frame, comprising a base plate 1 for supporting a puncture needle 2 and a drainage tube, wherein the base plate 1 is provided with a positioning structure for limiting the relative position between the base plate 1 and the patient and limiting the direction of the puncture needle 2; The positioning structure includes a horizontal sliding seat 3 arranged on a base plate 1, a horizontal sliding groove for the horizontal sliding seat 3 to slide horizontally is provided on the base plate 1, a four-claw frame 5 is fixedly connected to the horizontal sliding seat 3, a positioning assembly for fixing the puncture needle 2 is provided on the four-claw frame 5, and an axial swing assembly for adjusting the direction of the positioning assembly is also provided on the four-claw frame 5; A group of hollow cylinders 29 are fixedly connected to the horizontal sides of the base plate 1, respectively. The hollow cylinders 29 are provided with cylindrical suction nozzles 30 that contact the patient's skin tissue, and the hollow cylinders 29 are provided with a circular cavity for the cylindrical suction nozzles 30 to be slidably connected. The base plate 1 is provided with a pressure suction component that drives the cylindrical suction nozzles 30 to be negatively pressured and adsorbed onto the patient's skin tissue; The base plate 1 includes a plurality of groups of integrally formed side ears 101 , and the side ears 101 are provided with positioning components to prevent the drainage tube from falling off.

[0019] like Figure 1 , Figure 2 and Figure 5As shown, when performing lung puncture drainage on a patient, the base plate 1 is placed on the patient's back. After the puncture position is determined, the base plate 1 is adsorbed and fixed on the patient's back skin tissue through the pressure-suction component. At the same time, before the puncture operation, the puncture needle 2 is fixed by the positioning component, and after the position of the base plate 1 is determined, the horizontal position of the positioning component and the puncture needle 2 thereon is changed by sliding the horizontal sliding seat 3 so that it roughly corresponds to the puncture position.

[0020] At the same time, the orientation of the positioning assembly and the puncture needle 2 thereon is adjusted through the axial swing assembly to drive the puncture needle 2 to be oriented to the set angle and puncture position. The axial swing assembly allows medical staff to flexibly adjust the direction and angle of the puncture needle 2 according to medical needs to ensure that the puncture needle 2 can accurately enter the target position and avoid accidental injury to other tissues.

[0021] Furthermore, after the puncture needle 2 reaches the set depth, the drainage tube is inserted into the patient's body through the inner cavity of the puncture needle 2, and it is ensured that the end of the drainage tube reaches the fluid accumulation area. After confirming that the drainage tube is in the correct position, the puncture needle 2 is carefully pulled out of the patient's body while keeping the drainage tube in the patient's body. At this time, the drainage tube is clamped and fixed by the positioning component to ensure that it will not move or fall off during the drainage process.

[0022] Among them, the existing method of fixing the drainage tube is usually a threading fixation method, which requires threading at the patient's puncture site and winding the wire on the drainage tube to ensure that the drainage tube will not shift or fall off. This article uses a positioning component to replace the threading fixation method, simplify the operation process, and use the pressure-suction component to adsorb and fix the substrate 1 on the patient's back skin tissue. At the same time, the positioning component is used to fix the drainage tube to the substrate 1, thereby preventing the drainage tube from falling off due to the patient's movement, thereby ensuring that the drainage tube can drain the accumulated fluid more effectively and allow the accumulated fluid to be discharged from the body smoothly.

[0023] In order to ensure the horizontal position of the transverse sliding seat 3 and the components thereon, a plurality of transverse locking bolts 4 are threadedly connected to the transverse sliding seat 3, and the lower surface of the transverse locking bolts 4 is in pressure contact with the base plate 1, pushing the transverse sliding seat 3 to drive the puncture needle 2 supported by the positioning assembly thereon to move horizontally, and making the puncture needle 2 correspond to the set puncture position, and then by rotating the transverse locking bolt 4, the bottom of the transverse locking bolt 4 is driven to be in pressure contact with the base plate 1, and the contact surface between the base plate 1 and the transverse locking bolt 4 is frictionally treated, so that the friction force between the transverse locking bolt 4 and the base plate 1 is used to ensure the stability of the puncture needle 2 during the puncture process.

[0024] In one of the more preferred embodiments, the shaft swing assembly comprises a middle sphere 6 arranged on a four-claw frame 5, an inner arc seat 7 and an outer arc seat 10 are arranged on the middle sphere 6, the inner arc seat 7 is fixedly rotated on the four-claw frame 5, and a longitudinal shaft groove 8 for sliding connection of the inner arc seat 7 and a transverse shaft groove 9 for sliding connection of the outer arc seat 10 are respectively opened on the middle sphere 6; A turning column 13 is fixedly connected to a side of the outer arc seat 10 away from the middle sphere 6, and the four-claw frame 5 is provided with longitudinal arc plates 11 and transverse arc plates 12 which are staggered and have different distances from the center of the middle sphere 6. Both ends of the longitudinal arc plates 11 and the transverse arc plates 12 are fixedly rotated on the four-claw frame 5, and the longitudinal arc plates 11 and the transverse arc plates 12 are provided with arc grooves for the turning column 13 to slide through.

[0025] A set of worm wheels 15 are coaxially fixed to the ends of the longitudinal arc plate 11 and the transverse arc plate 12 , respectively. The two sets of worm wheels 15 are respectively meshed and connected with a set of worms 14 , and both ends of the worms 14 are fixedly rotated on the four-claw frame 5 .

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, by rotating the worm 14 at the corresponding position, the worm wheel 15 meshing with it is driven to rotate, thereby driving the longitudinal arc plate 11 or the transverse arc plate 12 coaxial with the worm wheel 15 to rotate, wherein the longitudinal arc plate 11 rotates in the horizontal direction, and the transverse arc plate 12 rotates in the vertical direction. When the longitudinal arc plate 11 rotates horizontally, it can push the turning column 13 passing through it, and drive the outer arc seat 10 and the locking assembly to deflect horizontally synchronously through the turning column 13, so as to change the horizontal deflection of the puncture needle 2 restricted on the locking assembly.

[0027] At the same time, when the longitudinal arc plate 11 rotates horizontally, it cannot swing horizontally due to the limitation of the middle sphere 6. Therefore, when the longitudinal arc plate 11 rotates, it can drive the outer arc seat 10 to slide on the transverse axial groove 9 through the turning column 13, thereby changing the horizontal orientation of the outer arc seat 10.

[0028] Moreover, when the transverse arc plate 12 swings in the vertical direction, since the outer arc seat 10 cannot swing relative to the middle sphere 6 in the vertical direction due to the restriction of the middle sphere 6, the middle sphere 6 can be driven to swing synchronously in the vertical direction through the outer arc seat 10. At this time, the inner arc seat 7 slides relative to the middle sphere 6 through the longitudinal axial groove 8, thereby adapting to the change of the pitch angle of the middle sphere 6 and the outer arc seat 10, and changing the pitch angle of the positioning assembly and the puncture needle 2 thereon through the change of the pitch angle of the outer arc seat 10.

[0029] It should be noted that by driving the worm 14 at the corresponding position to rotate, the horizontal direction and pitch angle of the puncture needle 2 can be changed, and by adjusting the horizontal relative position of the horizontal sliding seat 3 and the base plate 1, the direction of the puncture needle 2 can be dynamically adjusted when the puncture needle 2 is supported, thereby meeting the medical needs of different insertion angles.

[0030] Based on the embodiment of the shaft swing assembly, the positioning assembly includes a positioning strip 16 fixedly connected to the crook 13, a movable strip 17 is provided on the positioning strip 16, and a groove body 1 is provided on the positioning strip 16 for the movable strip 17 to be slidably connected, and the positioning strip 16 and the movable strip 17 jointly fix the puncture needle 2; The positioning strip plate 16 is threadedly connected with an internal pressure bolt 18 , and one end of the internal pressure bolt 18 is axially rotated on the movable strip plate 17 toward the movable strip plate 17 .

[0031] like Figure 1 and Figure 4 As shown, when fixing the puncture needle 2, the puncture needle 2 is placed between the circular grooves between the positioning strip 16 and the movable strip 17, and the internal pressure bolt 18 is screwed to drive the movable strip 17 to slide on the positioning strip 16 under the push of the internal pressure bolt 18, and the circular grooves on both are in contact with the surface of the puncture needle 2, thereby completing the positioning of the puncture needle 2, and subsequently the horizontal orientation and pitch angle of the positioning strip 16 are changed through the shaft swing assembly through the crank post 13 to ensure that the puncture needle 2 reaches the set puncture angle.

[0032] It should be noted that the circular grooves of the positioning strip 16 and the movable strip 17 are smoothed during actual use, so as to ensure that the puncture needle 2 can move axially in the circular grooves of the two to ensure the smooth progress of the puncture process. At the same time, after the movable strip 17 and the positioning strip 16 have completed the fixation of the puncture needle 2, in the subsequent puncture process, the movable strip 17 can be driven slightly away from the positioning strip 16 by screwing the internal pressure bolt 18, thereby avoiding excessive puncture resistance and ensuring the smooth progress of the puncture process.

[0033] Based on the embodiment of the positioning assembly, the pressure-suction assembly includes a return air cylinder 28 fixedly connected to the base plate 1, the inner wall of the return air cylinder 28 is in sliding contact with a piston plate 27, a T-shaped rod 25 is fixedly connected to the piston plate 27, and the T-shaped rod 25 reciprocates in the horizontal direction, and the return air cylinder 28 includes an integrally formed air inlet end and an air outlet end; A connecting hose 31 is fixedly passed through the cylindrical suction nozzle 30 , and one end of the connecting hose 31 away from the cylindrical suction nozzle 30 passes through the hollow cylinder 29 and is fixedly passed through the air inlet end. A limiting bolt is threadedly connected to the hollow cylinder 29 , and the limiting bolt is in pressure contact with the cylindrical suction nozzle 30 .

[0034] like Figure 1 , Figure 2 and Fig. 9 As shown, when the T-shaped rod 25 reciprocates in the horizontal direction, it can drive the piston plate 27 fixedly connected thereto to slide reciprocatingly in the return air cylinder 28, thereby realizing the reciprocating suction and discharge process of the gas in the return air cylinder 28, wherein the air inlet end of the return air cylinder 28 is fixedly connected to the cylindrical suction nozzle 30 through the connecting hose 31, so that when the piston plate 27 reciprocates horizontally, the gas in the two groups of cylindrical suction nozzles 30 can be repeatedly extracted, so that negative pressure is formed in the enclosed space composed of the cylindrical suction nozzles 30 and the patient's skin tissue, so as to ensure the stability of the substrate 1 and the components thereon through the adsorption of the two groups of cylindrical suction nozzles 30.

[0035] It should be noted that, in actual use, the contact area between the cylindrical suction nozzle 30 and the skin surface can be increased by increasing the diameter of the cylindrical suction nozzle 30, or the number of the cylindrical suction nozzles 30 can be increased to improve the stability of the substrate 1, and when there is a height difference in the skin tissue corresponding to the multiple groups of cylindrical suction nozzles 30, the cylindrical suction nozzle 30 can be extended or retracted into the hollow tube 29 by loosening the limit bolt to ensure that the multiple groups of cylindrical suction nozzles 30 can be in contact with the patient's skin surface, and then the limit bolt can be rotated to drive the limit bolt to squeeze and resist the cylindrical suction nozzle 30, thereby determining the relative position of the cylindrical suction nozzle 30 and the hollow tube 29.

[0036] At the same time, a group of one-way valves are respectively provided on the air inlet end and the air outlet end integrally formed on the air return cylinder 28, and the valve openings of the two groups of one-way valves are in opposite directions, so that the gas at the cylindrical suction nozzle 30 enters the air return cylinder 28 through the connecting hose 31 and is discharged to the external natural air through the air outlet end. When it is necessary to separate the cylindrical suction nozzle 30 from the patient, the air plug provided on the cylindrical suction nozzle 30 can be pulled out to drive the external air into the cylindrical suction nozzle 30, thereby achieving the purpose of separating the cylindrical suction nozzle 30 from the patient.

[0037] Based on the embodiment of the pressure-absorption assembly, the positioning assembly includes a resistance disk 32 that rotates freely in the horizontal direction, the resistance disk 32 rotates on the side ear portion 101 with a fixed axis, and two groups of notched clamps 35 that move synchronously toward or away from each other in the horizontal direction are provided above the resistance disk 32, and the two groups of notched clamps 35 jointly clamp and fix the drainage tube; The side ear portion 101 is provided with a second groove body for the notch clamping block 35 to be slidably connected, and the notch clamping block 35 is fixedly connected to the limit pin 33 at one end facing the blocking plate 32, and the blocking plate 32 is provided with a flower-shaped groove 34 for the limit pin 33 to be slidably connected.

[0038] The side ear portion 101 is provided with a center disk 19 driven by a motor and freely rotating in the horizontal direction. The center disk 19 rotates on the side ear portion 101 with a fixed axis. The outer circumference of the center disk 19 rotates with a fixed axis to form multiple groups of outer ratchets 20, and the inner circumference of the center disk 19 rotates with a fixed axis to form multiple groups of inner ratchets 21. The side ear portion 101 has an outer ratchet 22 and an inner ratchet 23 which are coaxially arranged with the center disk 19 and are rotatable on a fixed axis. The outer ratchet 22 is meshedly connected with the inner pawl 21, and the outer pawl 20 is meshedly connected with the inner ratchet 23. The inner ratchet 23 is fixedly connected with a co-ordination pin 24 at one end facing the T-shaped rod 25. The T-shaped rod 25 is provided with a co-ordination groove 26 for the sliding connection of the co-ordination pin 24. The outer ratchet 22 is transmission-connected with the blocking disk 32.

[0039] Figure 2 , Figure 6 , Figure 7 and Figure 8 As shown, when the center disk 19 rotates forward, the multiple groups of inner ratchet pawls 21 arranged thereon do not engage with the outer ratchet disk 22, but the multiple groups of outer ratchet pawls 20 arranged on its outer circumference can drive the inner ratchet disk 23 to rotate synchronously in the horizontal direction, wherein the isochronous pins 24 fixedly arranged on the inner ratchet disk 23 are slidably connected to the T-shaped rod 25 through the isochronous grooves 26, and then when the inner ratchet disk 23 rotates horizontally, the isochronous pins 24 can drive the T-shaped rod 25 to slide reciprocatingly in the horizontal direction to drive the pressure-suction assembly to operate.

[0040] In actual use, the center disk 19 can be driven to rotate by a motor fixed on the base plate 1, so that the motor and the center disk 19 are connected in transmission, or the center disk 19 can be rotated horizontally by manual means. At the same time, when the center disk 19 rotates in the opposite direction, it drives the outer ratchet disk 22 to rotate through multiple groups of inner ratchets 21, and in this process, the inner ratchet disk 23 does not rotate synchronously with it. When the outer ratchet disk 22 rotates, it can drive the blocking disk 32 connected in transmission with it to rotate synchronously, thereby driving the positioning assembly to operate. It should be noted that both the blocking disk 32 and the outer ratchet disk 22 rotate horizontally, and in actual use, pulleys can be set on both of them, and the synchronous rotation of the two can be achieved through the transmission between the belts, or the purpose of synchronous rotation of the two can be achieved through the meshing process between adjacent gears.

[0041] At the same time, when the resistance disk 32 rotates with the outer ratchet disk 22, the relative position between the limit pin 33 and the flower-shaped groove 34 can be changed. At the same time, since the notch clamp 35 is slidably set on the side ear 101 through the second groove body, the horizontal spacing between the two groups of notch clamps 35 is changed with the rotation of the resistance disk 32. When clamping and fixing the drainage tube, the relative surfaces of the two groups of notch clamps 35 are driven to press against the drainage tube, and the relative surfaces of the two groups of notch clamps 35 are arc-shaped structures, thereby increasing the contact surface with the drainage tube, thereby achieving the purpose of fixing the drainage tube to prevent the drainage tube from moving or falling off, thereby ensuring that the drainage tube can drain the accumulated fluid more effectively and allow the accumulated fluid to be discharged from the body smoothly.

[0042] 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.
