In order to achieve the technical effect, the technical scheme adopted by the embodiment is as follows:

as shown in fig. 1, the inner wall of the front part of the holding tube 7 is provided with a plurality of second linear rails 44, the number of the second linear rails 44 is the same as that of the fire needle body 1, the second linear rails 44 are distributed along the length direction of the holding tube 7, and the plurality of second linear rails 44 are uniformly distributed along the circumferential direction of the front part of the holding tube 7 at intervals. Any one second linear rail 44 is provided with a needle base 2, the needle base 2 is clamped on the second linear rail 44 and can freely slide along the second linear rail 44, and the front end of the needle base 2 is connected with the fire needle body 1 in a one-to-one correspondence manner. The basal portion of the fire needle body 1 is detachably connected on the needle seat 2, and the tip of the fire needle body 1 can penetrate out of the holding tube 7 from a through hole arranged at the front end of the holding tube 7 in the sliding process along with the needle seat 2.

The inner wall position of the front part in the holding tube 7 is provided with the heating mechanisms 12 with the same number as the fire needle bodies 1, and the heating mechanisms 12 comprise heating elements and second starting switches 6. Wherein the heating element is a resistance wire or an open flame nozzle which is conventional in the prior art, the heating element is arranged at two sides of the second wire rail 44 to avoid interference with the sliding of the needle seat 2, and the second starting switch 6 is arranged at the rear end of the second wire rail 44 and is touched and started by the needle seat 2.

The driving mechanism is a short handle 11 connected with the needle base 2, the short handle 11 slides in a through strip-shaped hole 9 arranged on the tube wall of the holding tube 7, and a first thread rail 10 for the sliding fit of the short handle 11 is arranged in the strip-shaped hole 9. One end of the short handle 11, which is positioned outside the holding tube 7, forms a first operating part 8, so that a doctor can drive the fire needle body 1 to slide by pushing and pulling the first operating part 8. Because the strip-shaped hole 9 that runs through has communicated the pipe 7 inner chamber and the outside of gripping, in order to avoid gripping 7 in the pipe high temperature air hurt people, be equipped with the thermal-insulated ring 4 that refractory material made in the position that corresponds the heating element on the pipe 7 that grips in this embodiment, and set up strip-shaped hole 9 in the pipe 7 that grips the position that is close to the rear end to link to each other short handle 11 and needle file 2 through extension rod 5.

The implementation process of this embodiment is as follows:

as shown in fig. 1, after the upper fire needle body 1 is cooled, the first operating part 8 of the upper short handle 11 is pushed back first, the front part of the upper fire needle body 1 is moved to the upper heating element position by the upper needle base 2, and the needle base 2 touches the second start switch 6 after sliding along the first linear rail 10 to the right end of the first linear rail 10, so that the upper heating element starts to heat the upper fire needle body 1. Then the second operation part 23 of the lower short handle 11 is pushed forward, the front part of the lower fire needle body 1 extends out of the front end of the holding tube 7 by the lower needle base 2, and then the fire needle puncture treatment is carried out on the patient by the doctor. At the moment, the lower needle base 2 leaves the lower second starting switch 6, and the lower heating element stops heating, so that energy is saved.

In this embodiment, in order to prevent the fire needle body 1 from retracting due to the reverse action force of the skin of the patient during the puncture treatment, the bottom of the front end of the second linear rail 44 is provided with the positioning mechanism 3. The positioning mechanism 3 includes a blind hole opened at the bottom of the second wire rail 44 and a positioning ball 302 disposed in the blind hole by a positioning spring 301. The positioning spring 301 is in a compressed state, and a circular groove corresponding to the shape of the positioning ball 302 is formed on the side surface of the needle seat 2 facing the bottom of the second track 44. In the state shown in fig. 1, the positioning ball 302 located above is engaged with the circular groove on the upper needle base 2 under the pushing force of the positioning spring 301, so as to prevent the fire needle body 1 from moving back during the puncture treatment. Similarly, the bottom of the rear end of the second wire track 44 is also provided with a positioning mechanism 3, and the positioning mechanism 3 is used for fixing the position of the needle base 2 at the rear end of the second wire track 44, so that the needle base 2 can continuously act on the second starting switch 6, the corresponding heating element can continuously heat the corresponding fire needle body 1, and the second starting switch 6 can select a spring type press switch which is common in the conventional technology and has low cost.

Example 2

Similar to embodiment 1, a plurality of fire needle bodies 1 in this embodiment are respectively fixed to needle bases 2 slidably provided on the inner wall of a holding tube 7, and heating mechanisms 12 for heating the fire needle bodies 1 after they are slid into the holding tube 7 are respectively provided in the holding tube 7. Different from the embodiment 1, the present embodiment only has two fire needle bodies 1 for the alternate operation of the doctor, the circumferential direction of the holding tube 7 is closed, and the driving mechanism mainly comprises a needle feeding spring 15 for pushing the needle seat 2 forward to make the corresponding fire needle body 1 extend out from the holding tube 7 and a push handle 28 for pushing the needle seat 2 backward to make the corresponding fire needle body 1 move to the position of the heating mechanism 12. As shown in fig. 2, one end of the needle feeding spring 15 is connected to the needle holder 2, and the other end is fixed to the rear end of the second linear rail 44. The push handle 28 is rotatably arranged on a nut 27, the outer periphery of the nut 27 is rotatably provided with a rotating ring 13 through a bearing, the push handle 28 is L-shaped, the base part of the push handle is fixed on the rotating ring 13, and the end part of the push handle points to the rear end direction of the holding tube 7. The nut 27 is fitted on a lead screw 26 which is distributed along the length of the grip tube 7 and is driven to rotate by a motor 29. The motor 29 is rotatable in forward and reverse directions to drive the nut 27 and the push handle 28 thereon to reciprocate along the length direction of the grip pipe 7 through the cooperation of the lead screw 26 and the nut 27.

In addition, the driving mechanism in this embodiment further includes a rotating disk 17 concentrically distributed in the holding tube 7 and a switching mechanism for driving the rotating disk 17 to rotate. Two through holes are formed in the rotary table 17, the linkage rods 14 are slidably inserted into the through holes, and the left ends of the linkage rods 14 penetrate through the through holes and then are fixedly connected with the rotating ring 13, so that the rotating ring 13 and the push handle 28 on the rotating ring 17 can be synchronously driven to rotate when the rotary table rotates. The side of the rotary disk 17 corresponding to the rear end of the holding tube 7 (i.e. the right side of the rotary disk 17) forms a positioning surface for the needle holder 2 to contact and press the needle feeding spring 15. As shown in fig. 4, the turntable 17 is provided with an ejection window 16 through which the needle holder 2 is ejected from the positioning surface by the urging force of the needle feeding spring 15, and a storage window 25 through which the needle holder 2 enters the positioning surface by the urging force of the urging lever 28. The rotary table 17 can rotate to and fro under the action of the switching mechanism, so that the needle bases 2 corresponding to the two fire needle bodies 1 can respectively correspond to and coincide with the ejection windows 16 and the containing windows 25 on the rotary table 17. The receiving window 25 is overlapped with the projection of the push handle 28 in the length direction of the holding tube 7, and a one-way opening plate 24 for the needle holder 2 to pass through is arranged at the receiving window 25. As shown in fig. 8-10, the one-way opening plate 24 and the rotary plate 17 both have a certain thickness, and the right side of the one-way opening plate 24 is pinned with the right side of the rotary plate 17 by the connecting pin 32, so that the one-way opening plate 24 can only rotate towards the right side to open the accommodating window 25, but not rotate towards the left side, thereby achieving the effect of opening the accommodating window 25 in one direction of the one-way opening plate 24, and further achieving the effect that the one-way opening plate 24 blocks the needle seat 2 to press the needle feeding spring 15. The pin joint position of the one-way opening and closing plate 24 and the rotary disc 17 is also provided with a torsion spring 33, so that after the one-way opening and closing plate 24 is opened under the action of external force, the one-way opening and closing plate 24 can automatically enter the pipe wall state to seal the storage window 25 by potential energy generated by the torsion spring 33 in the state that the external force disappears.

The switching mechanism comprises first sleeves 19 of first drums 18 each distributed along the length of the grip tube 7. The first rotary drum 18 can only rotate in the holding tube 7 and can not move along the length direction of the holding tube 7; the first sleeve 19 can only move along the length direction of the holding tube 7 but can not rotate, and the above effect can be achieved through a conventional limiting mode. The left end of the first rotary drum 18 is concentrically fixed with the right side of the rotary table 17, the right end of the lead screw 26 is a polished rod, penetrates through a central hole formed in the rotary table 17, and then is matched with the inside of the left end of the first rotary drum 18 through a bearing (not shown in the figure), and the rotary table 17 and the push handle 28 are driven to synchronously rotate at equal angles by rotating the first rotary drum 18. The first sleeve 19 is sleeved between the holding pipe 7 and the first rotating cylinder 18, a plurality of sliding blocks 22 are arranged on the outer wall of the first sleeve 19 at intervals, sliding grooves 20 for the sliding of the sliding blocks 22 are correspondingly arranged on the inner wall of the holding pipe 7, and the first sleeve 19 can only slide along the length direction of the holding pipe 7 and cannot rotate under the driving of external force through the matching of the sliding blocks 22 and the sliding grooves 20. The inner wall of the first sleeve 19 is provided with first convex columns 21 distributed along the radial direction of the first sleeve, and the outer wall of the first rotary drum 18 is provided with a first stroke groove 31 for the first convex columns 21 to be inserted and matched in a sliding mode. As shown in fig. 3, the first travel grooves 31 are formed in a spiral shape substantially along the circumferential direction of the outer wall of the first drum 18. In the state shown in fig. 3, the first protruding pillar 21 is located at the right end of the first stroke slot 31, and at this time, after the first protruding pillar 21 slides leftward along the holding tube 7 along with the first sleeve 19, the first rotating cylinder 18 is driven by the first protruding pillar 21 to rotate clockwise, so that the first rotating cylinder 18 drives the rotating disc 17 and the pushing handle 28 to rotate. When the first protruding column 21 reaches the left end of the first stroke slot 31, the first sleeve 19 is moved rightwards in the opposite direction, that is, the first protruding column 21 drives the first rotary drum 18 to rotate in the counterclockwise direction. The first sleeve 19 is pushed and pulled in a reciprocating manner, so that the rotary disc 17 and the push handle 28 are driven to rotate in reverse repeatedly.

In fig. 3, two ends of the first stroke slot 31 are closed and respectively provided with a first start switch 30 for starting the rotation of the motor 29, and the first start switch 30 is triggered by the touch of the first convex column 21. The motor 29 is also provided with a time-delay reverse control circuit which comprises a conventional single chip microcomputer or a relay combination and is used for driving the push handle 28 on the nut 27 to move towards the rear end direction of the holding tube 7 and send the corresponding needle seat 2 to the positioning surface through the one-way opening-closing plate 24 and then move towards the front end direction of the holding tube 7 through the forward and reverse rotation of the output shaft of the motor 29 after the motor 29 is started.

The implementation process of this embodiment is as follows:

in the state shown in fig. 2, the upper fire needle body 1 is used for puncture needle application treatment, and the lower fire needle body 1 is located in the corresponding heating element and is continuously heated. After the upper fire needle body 1 is cooled, the first sleeve 19 is pushed rightwards to switch the operation of the fire needle body 1.

Firstly, after the first sleeve 19 moves to the right, the first cylinder 18 is driven to rotate 180 ° by the first convex column 21 and the first stroke groove 31, and the rotation of the first cylinder 18 drives the rotary table 17 and the push handle 28 to rotate 180 ° to the state shown in fig. 5. Wherein, the push handle 28 is positioned at the left side of the upper needle stand 2 after rotating 180 degrees; after the rotary disc 17 rotates 180 degrees, the ejecting window 16 and the receiving window 25 on the rotary disc 17 exchange positions with each other, namely the receiving window 25 is opposite to the upper needle base 2, and the ejecting window 16 is opposite to the lower needle base 2. The lower needle holder 2 is ejected from the ejection window 16 by the action of the lower needle feeding spring 15 in a compressed state, so that the lower fire needle body 1 extends out from the front end of the holding tube 7 to the state shown in fig. 6, and the puncture treatment is performed by the doctor. In order to avoid energy waste, the heating element corresponding to the ejected fire needle body 1 in this embodiment is also stopped from heating by the second start switch 6 corresponding to the needle base 2, and the structural principle is the same as that in embodiment 1, which is not shown in this embodiment and will not be described again. The needle seat 2 in the puncture treatment is still positioned by the positioning mechanism 3 similar to that in the embodiment 1, so that the skin of a patient is prevented from generating reaction force on the fire needle body 1 to retreat the fire needle body 1.

Then, after the first convex column 21 moves to the left end of the first stroke groove 31, the first start switch 30 at the corresponding position is triggered, the output shaft of the motor 29 rotates forward to push the nut 27 to move right, and the push handle 28 shown in fig. 6 moves right along with the nut 27 and pushes the upper needle base 2 to move right, and simultaneously compresses the upper needle feeding spring 15. After the upper needle base 2 contacts with the one-way opening plate 24 at the position of the receiving window 25 as shown in fig. 7 and 8, the needle base 2 is pushed by the push handle 28 to move rightward with the continuous forward rotation of the output shaft of the motor 29, and the one-way opening plate 24 rotates rightward with the connecting pin 32 as the center as shown in fig. 9, so that the receiving window 25 is opened to allow the needle base 2 to pass through, and at this time, the torsion spring 33 is forced to compress. After the needle base 2 is integrally moved to the right to be separated from the outer edge of the one-way opening and closing plate 24, as shown in fig. 10, the one-way opening and closing plate 24 rebounds to block the accommodating window 25 under the potential energy of the torsion spring 33. At this time, the output shaft of the motor 29 rotates reversely, the nut 27 drives the push handle 28 to move left, the upper needle base 2 loses the left thrust and is pushed against the right position of the one-way opening-closing plate 24 under the action of the right needle feeding spring 15, and the state shown in fig. 11 is achieved. The upper fire needle body 1 is heated by the corresponding heating element under the matching of the corresponding needle seat 2 and the second starting switch 6, and the push handle 28 moves to a position close to the front end of the holding pipe 7 under the continuous reverse rotation action of the output shaft of the motor 29 to prepare for the switching of the next fire needle body 1.

In the state of fig. 11, after the lower fire needle body 1 is cooled, the first sleeve 19 is pulled outwards to rotate the first rotary drum 18 reversely by 180 degrees again, the upper heated fire needle body 1 is ejected again to perform puncture treatment according to the above process, and the lower fire needle body 1 is pushed into the holding tube 7 to be heated. The process is repeated, and continuous puncture treatment is realized through different fire needle bodies 1.

In order to facilitate the doctor to control the left-right reciprocating movement of the first sleeve 19 with one hand in the embodiment, the other hand is completely released, and a second operating part 23 for the thumb to push the first sleeve 19 forward and backward along the holding tube 7 in a forward pressing or backward pushing manner is further arranged at the rear end position of the first sleeve 19. The second operation part 23 is vertically fixed at the rear end of the first sleeve 19, and when the doctor grasps the holding tube 7, the second operation part 23 is pressed left by the thumb to drive the first sleeve 19 to move left, and the second operation part 23 is pressed right by the thumb to drive the first sleeve 19 to move right.

Example 3

The structure and principle (needle feeding spring 15, rotary table 17-pop-up window 16, storage window 25, one-way opening plate 24, push handle 28-rotating ring 13-linkage rod 14, bearing-nut 27-lead screw 26-motor 29) for pushing fire needle body 1 out of holding tube 7 for puncture treatment and feeding fire needle body 1 into holding tube 7 for continuous heating in this embodiment are the same as those in embodiment 2, and the difference is that the number of fire needle bodies 1 in this embodiment is more than three (four in this embodiment), and the fire needle device is suitable for use in a low-temperature environment or under the condition that the cooling speed of relatively small fire needle bodies 1 is too high. The switching mechanism for driving the rotation of the rotary plate 17 and the push handle 28 is similar to that of embodiment 2, and has a second sleeve 36 similar to the first sleeve 19 of embodiment 2 as a switching member, except that in this embodiment, switching is performed by pressing the second sleeve 36 once, and the second sleeve 36 is rebounded to the initial state by the return spring 35 after being pressed, so as to prepare for the next switching by pressing the second sleeve 36, specifically:

as shown in fig. 12, the switching mechanism includes a second drum 34, the second sleeve 36, and a return spring 35, all of which are distributed along the longitudinal direction of the grip tube 7. The second drum 34 is fixed at the center of the turntable 17, and the second sleeve 36 is slidably fitted on the inner wall of the grip tube 7 in the longitudinal direction of the grip tube 7 (the same as in embodiment 2). The rear end of the second sleeve 36 is distributed outside the grip tube 7 and forms a third operation portion 38 for pressing operation. The left end of the return spring 35 is fixed with an annular spring seat fixed on the inner wall of the holding tube 7 through a support rod, and the right end is fixed with the left end of the second sleeve 36. After the second sleeve 36 is pressed by the third operating portion 38, the return spring 35 is compressed and pushes the second sleeve 36 to the initial state shown in fig. 12 after the external force of the third operating portion 38 disappears.

The inner side of the second sleeve 36 is provided with a second convex column 37, and the outer side of the second rotary drum 34 is provided with a stroke slot group for the second convex column 37 to be inserted and matched in a sliding way. The number of the stroke slot groups and the number of the fire needle bodies 1 are four, and each stroke slot group comprises a second stroke slot 42 and a third stroke slot 43. As shown in FIG. 13, the second grooves 42 are helically distributed along the outer wall of the second drum 34 and are open at both ends, and the third grooves 43 are distributed along the length of the second drum 34 and are open at both ends. The right open end of the travel groove set is located on the right end face of the second drum 34, and the left open end is located on the left end face of the boss shape on the second drum 34. The front ends of the second and third travel slots 42, 43 in the same row Cheng Caozu are adjacent to each other, as indicated by open ends b and c in fig. 13, and the rear ends of the third and second travel slots 43, 42 in adjacent sets of travel slots are adjacent to each other, as indicated by open ends d and e in fig. 13. In the embodiment, when the second cylinder 37 is located at the open end a in fig. 13, when the third operating portion 38 is pressed to move the second cylinder 37 to the left, that is, the second cylinder 34 is moved along the second stroke groove 42 shown by a-b and rotated in the direction of the needle by pushing the third operating portion 38, after the second cylinder 37 is disengaged from the open end b, the second cylinder 34 needs to be driven to continue the first auxiliary rotation with a small amplitude to make the second cylinder 37 correspond to the open end c, then the second cylinder 34 is moved to the right by the thrust of the return spring 35 to disengage the second cylinder 37 from the corresponding open end d, and then the second cylinder 34 needs to continue the second auxiliary rotation with a small amplitude to make the second cylinder 37 correspond to the open end e of the second stroke groove 42 in the next stroke groove, so as to reach the initial state again, and prepare for next pressing of the second sleeve 36 to switch the fire needle body 1. In order to realize the first auxiliary rotation and the second auxiliary rotation, the needle holder 2 and the dial 17 of the present embodiment have an auxiliary driving mechanism slightly different from that of embodiment 2:

as shown in fig. 14, the side of the needle holder 2 has an arc-shaped projection 39, and the arc-shaped projection 39 is used as an actuating member for the first auxiliary rotation and the second auxiliary rotation. The arc-shaped protrusion 39 has two arc-shaped or wedge-shaped surfaces, and the two arc-shaped or wedge-shaped surfaces are symmetrically distributed on the front and back sides of the needle base 2 along the sliding direction of the holding tube 7. The mating parts for the actuation of the arcuate projections 39 are located on the turntable 17 at the ejection window 16 and the receiving window 25 respectively. As shown in fig. 15, a visible first wedge surface 40 is provided on the turntable 17 toward the rear end of the holding tube 7 at a portion corresponding to the right side of the ejecting window 16, and a second wedge surface 41 is provided on the turntable 17 toward the front end of the holding tube 7 at a portion corresponding to the left side of the receiving window 25 (the structure may be the same as the first wedge surface 40, and is hidden due to the view angle). On the basis of the structure of the arc-shaped protrusion 39, the first wedge-shaped surface 40 and the second wedge-shaped surface 41 shown in fig. 14 and 15, as shown in fig. 16, when the rotating disc 17 is rotated to make the ejecting window 16 on the rotating disc correspond to the corresponding needle seat 2, and the front side of the arc-shaped protrusion 39 on the needle seat 2 is partially shielded from the first wedge-shaped surface 40, the needle feeding spring 15 still pushes the needle seat 2 to move forward, and the rotating disc 17 is driven to rotate by a certain angle through the cooperation of the front side of the arc-shaped protrusion 39 and the first wedge-shaped surface 40, and the rotating disc 17 drives the second sleeve 36 to rotate by the same angle to form the first auxiliary rotation. Similarly, as shown in fig. 17, when the rotating disc 17 rotates to make the receiving window 25 on it correspond to the needle holder 2, the main body of the needle holder 2 corresponds to the receiving window 25, and the arc-shaped projection 39 corresponds to the second wedge-shaped surface 41, as the needle holder 2 is continuously pushed back by the pushing handle 28, the rear side of the arc-shaped projection 39 cooperates with the second wedge-shaped surface 41 to push the rotating disc 17 to rotate by a certain angle, and the rotating disc 17 drives the second rotating drum 34 to rotate by the same angle to form the aforementioned second auxiliary rotation.

The implementation process of this embodiment is as follows:

in the state shown in fig. 12, the puncture treatment is performed by the uppermost one of the fire needle bodies 1. The fire needle body 1 and the fire needle are both positioned in the holding tube 7 and are respectively preheated by the corresponding heating mechanisms 12. After the uppermost fire needle body 1 is cooled, the doctor switches by pressing the third operating portion 38 leftward. At this time, also taking fig. 13 as an example, after the second sleeve 36 is pressed, the second stud 37 synchronously moves to the left and penetrates through a second stroke groove 42 in the direction a-b, and the second drum 34 rotates clockwise. The second rotary drum 34 rotates to drive the rotary table 17 and the push handle 28 to rotate, the needle seat 2 of the other fire needle body 1 is ejected out of the ejection window 16 on the rotary table 17 through the needle feeding spring 15, and the motor 29 is started to push the uppermost fire needle body 1 into the holding tube 7 through the push handle 28 for heating. The first auxiliary rotation is generated in the process of ejecting the needle seat 2 from the ejection window 16 on the rotary disc 17, so that the second convex column 37 corresponds to the end c of one third travel groove 43, and at the moment, after the pressing action of the third operating part 38 disappears, the second sleeve 36 penetrates through the third travel groove 43 in the c-d direction under the thrust action of the return spring 35 in a compressed state and is positioned on the right side of the right end surface of the second rotary drum 34; when the motor 29 is started to push the uppermost fire needle body 1 into the holding tube 7 through the push handle 28 for heating, the second auxiliary rotation is generated, so that the second convex column 37 corresponds to the open end e of the other second stroke groove 42, and when the fire needle body 1 is switched next time, the third operation part 38 can be directly pressed, that is, the second convex column 37 and the second stroke groove 42 are matched to drive the second rotary drum 34 to rotate again. The four fire needle bodies 1 extend out of the holding tube 7 one by one to realize continuous puncture treatment.
