Description

A non-pneumatic transoral endoscopic thyroid aspiration device Technical Field

[0001] This invention relates to the field of surgical instrument technology, and more specifically, to a non-inflatable transoral endoscopic thyroid puncture device. Background Technology

[0002] Transoral endoscopic thyroidectomy is a minimally invasive procedure. The procedure involves inserting a puncture device between the skin and muscles of the patient's neck through the mouth. The puncture device keeps the skin and muscles separated, and the doctor can observe the specific condition of the patient's thyroid gland through a monitor, thus enabling the surgical removal. Technical issues

[0003] However, the smoke generated during the operation can affect the observation of the oral endoscope, and the existing thyroid surgery puncture instrument cannot expel the gas in the surgical cavity during the operation, which reduces the surgical efficiency of medical staff and the effectiveness of the device. Technical solutions

[0004] This invention provides a non-inflatable transoral endoscopic thyroid aspiration device to solve the problem that existing thyroid aspiration devices cannot expel gas from the surgical cavity during surgery, thereby reducing the surgical efficiency of medical staff and the effectiveness of the device.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A non-inflatable transoral endoscopic thyroidectomy puncture device includes a puncture needle and an aspiration assembly. The aspiration assembly includes an inner cylinder disposed within the puncture needle. The outer side of the inner cylinder is connected to the inner wall of the puncture needle via multiple retaining blocks. The bottom end of the inner wall of the puncture needle is provided with an L-shaped block that slides vertically. A dovetail groove is formed on the L-shaped block, and a dovetail block is slidably engaged with the L-shaped block through the dovetail groove. A connecting block is provided at the top of the dovetail block. The tops of all the connecting blocks are connected to a vertical plate, and the tops of all the vertical plates are connected to a connecting plate. The vertical plates are connected by a retaining plate.

[0007] Preferably, a sliding button is provided on the outer side of the connecting block, and multiple guide grooves are provided on the inner wall of the puncture needle. The sliding button is slidably engaged in the guide grooves, and the inner and outer sides of the L-shaped block and the connecting block are respectively attached to the inner cylinder and the side wall of the puncture needle.

[0008] Preferably, the connecting plate has multiple ventilation slots, and the top of the inner wall of the puncture needle is provided with multiple blocks, the top of the blocks contacting the bottom of the ventilation slots.

[0009] Preferably, the puncture needle is provided with an outer cylinder, and a connecting ring is sleeved on the outer side of the puncture needle. The top end of the connecting ring is connected to the connecting plate by a spring, and a pair of pull plates are symmetrically arranged on the outer side of the connecting plate.

[0010] Preferably, a pair of sliding rods are connected to the bottom end of the connecting ring, two pairs of retaining plates are provided between the outer cylinder and the puncture needle, the sliding rods are slidably engaged in the pair of retaining plates, and a limit block is provided at the bottom end of the sliding rods. Beneficial effects

[0011] The principle and beneficial effects of this technical solution:

[0012] (1) The suction assembly provided in this invention can extract the gas in the surgical space at one end of the puncture needle, thereby helping medical staff to vent the surgical cavity. When using the suction assembly, rotate the connecting plate so that the multiple vertical plates connected to the bottom of the connecting plate rotate together. Since there is a connecting block at the bottom of the vertical plate, the connecting block is connected to the L-shaped block through the dovetail block. When the sliding button on the outside of the connecting block slides along the guide groove to the point where the connecting block and the L-shaped block jointly block the gap between the puncture needle and the inner cylinder, the stop block opened on the connecting plate is also misaligned with the stop block set at the top of the inner wall of the puncture needle. At this time, pull up the moving plate, and the L-shaped block and the connecting block will move up along the guide groove under the drive of the vertical plate. At this time, the gas in the surgical cavity, along with smoke, can be sucked into the gap between the puncture needle and the inner cylinder. Then, twist the connecting plate in the opposite direction so that the connecting block slides along the dovetail groove on the L-shaped block. At this time, the smoke stored in the cavity will drift from the gap between the L-shaped blocks into the upper part of the gap between the puncture needle and the inner cylinder, and finally be discharged from the surgical cavity, thereby avoiding affecting the line of sight of the oral endoscope.

[0013] (2) In this invention, the spring set by the connecting ring can help the user to quickly exhaust gas. When the connecting plate is rotated to the point where the sliding button at its bottom end is aligned with the groove of the vertical part of the guide groove, the spring will push the connecting plate a certain distance under the action of elasticity. At this time, a slight rotation of the connecting plate can complete one exhaust. When a large amount of exhaust is required, the user can continue to pull the connecting plate up by pulling the plate after the connecting plate is pushed up a certain distance by the spring, thereby increasing the amount of gas sucked up to improve the exhaust efficiency. At this time, the connecting ring will also move up a certain distance in sync. The movement stability of the connecting plate is maintained by the cooperation of the locking plate and the sliding rod. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments: Example:

[0023] As shown in Figures 1 to 7, the present invention provides a non-inflatable transoral endoscopic thyroid puncture device, including a puncture needle 5 and an air suction assembly. The air suction assembly includes an inner cylinder 8 disposed inside the puncture needle 5. The outer side of the inner cylinder 8 is connected to the inner wall of the puncture needle 5 through multiple retaining blocks 21. The bottom end of the inner wall of the puncture needle 5 is provided with an L-shaped block 19 that slides vertically. A dovetail groove 20 is provided on the L-shaped block 19. A dovetail block 17 is slidably engaged with the L-shaped block 19 through the dovetail groove 20. A connecting block 15 is provided at the top of the dovetail block 17. The tops of all connecting blocks 15 are connected to vertical plates 14. The tops of all vertical plates 14 are connected to a connecting plate 4. The vertical plates 14 are connected to each other by retaining plates 6.

[0024] As shown in Figures 2 to 4 and Figure 7, a sliding button 16 is provided on the outer side of the connecting block 15, and multiple guide grooves 18 are provided on the inner wall of the puncture needle 5. The sliding button 16 is slidably locked in the guide groove 18, and the inner and outer sides of the L-shaped block 19 and the connecting block 15 are respectively attached to the inner cylinder 8 and the side wall of the puncture needle 5.

[0025] As shown in Figures 1 to 3, the connecting plate 4 has multiple ventilation slots 1, and the top of the inner wall of the puncture needle 5 is provided with multiple blocks 7, the top of the blocks 7 contacting the bottom of the ventilation slots 1.

[0026] As shown in Figures 1 to 3, an outer cylinder 3 is provided on the outside of the puncture needle 5, and a connecting ring 11 is sleeved on the outside of the puncture needle 5. The top of the connecting ring 11 is connected to the connecting plate 4 through a spring 10. A pair of pull plates 2 are symmetrically arranged on the outside of the connecting plate 4.

[0027] As shown in Figures 1 to 4, a pair of sliding rods 12 are connected to the bottom end of the connecting ring 11. Two pairs of retaining plates 9 are provided between the outer cylinder 3 and the puncture needle 5. The sliding rod 12 is slidably secured in the pair of retaining plates 9. A limit block 13 is provided at the bottom end of the sliding rod 12.

[0028] The spring 10, which is connected to the connecting ring 11, helps the user to quickly vent gas. When the connecting plate 4 is rotated until the sliding button 16 at its bottom is aligned with the groove of the vertical part of the guide groove 18, the spring 10 will push the connecting plate 4 up a certain distance under the action of elasticity. At this time, a slight rotation of the connecting plate 4 can complete one venting operation. When a large amount of venting is required, the user can continue to pull the connecting plate 4 up by the pull plate 2 after the connecting plate 4 is pushed up a certain distance by the spring 10, thereby increasing the amount of gas sucked up to improve the venting efficiency. At this time, the connecting ring 11 will also move up a certain distance simultaneously. The movement stability of the connecting plate 4 is maintained by the cooperation of the locking plate 9 and the sliding rod 12.

[0029] The specific usage and function of this embodiment are as follows:

[0030] The air extraction component in this invention can extract gas from the surgical space at one end of the puncture needle 5, thereby helping medical staff to vent the surgical cavity. When using the air extraction component, rotating the connecting plate 4 causes the multiple vertical plates 14 connected to the bottom of the connecting plate 4 to rotate together. Since the bottom of the vertical plate 14 is provided with a connecting block 15, the connecting block 15 is connected to the L-shaped block 19 through the dovetail block 17. When the sliding button 16 on the outside of the connecting block 15 slides along the guide groove 18 until the connecting block 15 and the L-shaped block 19 together block the gap between the puncture needle 5 and the inner cylinder 8, the stop block 7 on the connecting plate 4 will then... It is also misaligned with the stop block 7 set at the top of the inner wall of the puncture needle 5. At this time, when the moving plate is pulled up, the L-shaped block 19 and the connecting block 15 will move up along the guide groove 18 under the drive of the vertical plate 14. At this time, the gas in the surgical cavity, along with smoke, can be drawn into the gap between the puncture needle 5 and the inner cylinder 8. Then, the connecting plate 4 is twisted in the opposite direction, so that the connecting block 15 slides along the dovetail groove 20 on the L-shaped block 19. At this time, the smoke stored in the cavity will drift from the gap between the L-shaped blocks 19 into the upper end of the gap between the puncture needle 5 and the inner cylinder 8, and finally be discharged from the surgical cavity, thereby avoiding affecting the view of the oral endoscope.
