Description

Technical Field

[0001] The present invention relates to the technical field of thyroid surgery irrigation devices, and particularly to a thyroid surgery irrigation device. Background Technique

[0002] During thyroid surgery, the bleeding from the wound surface and the debris generated by tissue cutting will quickly obscure the surgical field of view, affecting the surgeon's observation and operation of the anatomical structure. As an irrigation device, during use, by spraying normal saline or other suitable irrigation fluids, the blood can be diluted and washed away in a timely manner, and at the same time, the remaining tissue fragments can be removed. During the use of the irrigation device, a liquid suction head is used to absorb and collect the irrigated fluid and tissue fragments in a timely manner to avoid the impact of the irrigated fluid and tissue fragments after irrigation on the surgery.

[0003] During the irrigation process of the irrigation device, the use angle of the irrigation head on the irrigation device cannot be flexibly adjusted according to the irrigation pressure. For example, during the initial low-pressure irrigation, the irrigation head is kept relatively perpendicular to the position being irrigated during the surgery, and gently sprayed in a direction perpendicular to the surgical wound surface to avoid generating a lateral impact force on the fragile thyroid tissue or neurovascular vessels, reducing the risk of tissue damage. When the irrigation pressure increases, since the irrigation liquid exits perpendicular to the surgical wound surface and under the action of high pressure, the irrigation liquid will splash onto the surgical field or the endoscope lens, blurring the line of sight, and vertical high-pressure irrigation (pressure > 1 MPa) is likely to cause perforation of the thin-walled tissue due to the concentrated impact force. For this reason, we propose a thyroid surgery irrigation device. Summary of the Invention

[0035] It should be noted here that: a delivery pump for auxiliary delivery and a suction pump for suction are respectively arranged on the liquid extraction head 103 and the delivery pipe 104. As conventional technical components for transporting liquids, the working principles and operation methods of the delivery pump and the suction pump are regarded as existing technologies in this application and will not be elaborated here;

[0036] It is worth noting here that: the rubber diaphragm 106 is used for the partition seal between the inside and the outside of the operation box 101. The rubber diaphragm 106 is made of a flexible material, specifically silicone rubber. Through its own flexible effect, the rubber diaphragm 106 ensures sealing without affecting the movement of the flushing head 102 and the liquid extraction head 103.

[0037] It further includes:

[0038] A pressure regulating component, which is arranged on the rinsing head 102 for regulating the rinsing pressure;

[0039] A rotating component, which is arranged on the operation box 101 for rotating and adjusting the rinsing angle of the rinsing head 102 during the rinsing pressure regulation process;

[0040] A connecting component, which is arranged on the operation box 101 for assisting the rotatable connection of the liquid extraction head 103;

[0041] And, a swinging component which is arranged on the operation box 101 for assisting the swinging of the liquid extraction head 103 during use. A transmission component for driving the swinging component and a control component for controlling the swinging amplitude are arranged inside the operation box 101. A linkage component for assisting the linkage is arranged between the control component and the rotating component;

[0042] It should be noted here that: when the thyroid surgery rinsing device is in use, through the mutual cooperation of the pressure regulating component, the rotating component, the connecting component and the control component, the rinsing use angle between the rinsing head 102 and the rinsing position can be independently controlled according to the rinsing pressure. While avoiding the splashing of the rinsing liquid affecting the surgical vision during high-pressure and vertical rinsing, through the adjustment of the angle after pressurization, the impact force is decomposed into vertical and horizontal components, and the vertical impact force is reduced to avoid directly piercing the tissue. And during the rinsing process, through the swinging of the liquid extraction head 103 and the adaptive adjustment of the swinging amplitude according to the rinsing pressure, the recovery effect of the rinsing liquid and tissue fragments left after rinsing is ensured.

[0043] Preferably, the pressure regulating component includes a partition plate 201 fixed inside the rinsing head 102. A spherical groove 202 is rotatably connected to the partition plate 201. A sphere 203 which is arranged in a mutually matching manner is rotatably connected inside the spherical groove 202.

A driving component for driving the sphere 203 is arranged between the rinsing head 102 and the operation box 101; The driving component includes a driving shaft 301 rotatably connected to the rinsing head 102. One end of the driving shaft 301 is fixed to the sphere 203. The other end of the driving shaft 301 is located inside the operation box 101 and is fixed with a driving gear 302. An arc-shaped rack 303 is fixed inside the operation box 101. The driving gear 302 and the arc-shaped rack 303 are arranged in a mutually meshing manner;

[0044] It should be noted here that: the first motor 502 drives the rotating shaft 501 and the flushing head 102 at one end of the rotating shaft 501 to rotate. During the rotation of the flushing head 102, the drive shaft 301 is driven to rotate. During the movement of the drive shaft 301, through the meshing transmission between the drive gear 302 and the arc-shaped rack 303, the drive shaft 301 and the sphere 203 at one end of the drive shaft 301 are rotated. Through the rotation of the sphere 203, the through hole 204 rotates towards the inner side of the spherical groove 202, so that the through hole 204 and the spherical groove 202 are arranged in an interleaved manner, reducing the flow cross-sectional area of the flushing liquid on the flushing head 102. Under the action of the same conveying flow rate, the effect of flushing pressure increase is achieved.

[0045] Preferably, the rotating assembly includes a rotating shaft 501 rotatably connected inside the operation box 101. One end of the rotating shaft 501 is fixed to the outside of the flushing head 102. A first motor 502 for driving the rotating shaft 501 is installed on the outside of the operation box 101.

[0046] It should be noted here that: through the driving action of the first motor 502 and the connection action of the rotating shaft 501, the flushing head 102 is rotated.

[0047] Preferably, the connecting assembly includes two connecting shafts 601 fixed to the outside of the liquid extraction head 103, and the two connecting shafts 601 are arranged symmetrically. One of the connecting shafts 601 is rotatably connected to the inside of the operation box 101, and a connecting rod 602 is fixed to one end of the other connecting shaft 601.

[0048] It should be noted here that: through the connecting shaft 601, it is convenient to assist in the rotatable connection of the liquid extraction head 103. Through the connecting rod 602, it is convenient to drive the rotation of the liquid extraction head 103.

[0049] Preferably, the swinging assembly includes a sliding groove 701 formed on the connecting rod 602, and a sliding pin 702 is slidably connected to the sliding groove 701; the transmission assembly includes a mounting frame 801 arranged inside the operation box 101. A transmission plate 802 is arranged on the mounting frame 801. One end of the sliding pin 702 is rotatably connected to the transmission plate 802. A reciprocating lead screw 803 is rotatably connected to the mounting frame 801. A threaded sleeve 804 is fixed to the transmission plate 802, and the threaded sleeve 804 is meshed with the reciprocating lead screw 803. Two guide rods 805 are slidably connected to the transmission plate 802. The guide rods 805 are fixed inside the mounting frame 801, and the two guide rods 805 are symmetrically arranged on both sides of the reciprocating lead screw 803. A second motor 806 for driving the reciprocating lead screw 803 is installed on one side of the mounting frame 801.

[0050] It should be noted here that: the second motor 806 on the mounting frame 801 drives the reciprocating lead screw 803 to rotate. During the rotation of the reciprocating lead screw 803, through the meshing transmission between the reciprocating lead screw 803 and the threaded sleeve 804 and the guiding action of the sliding of the guide rod 805, the transmission plate 802 makes a horizontal reciprocating motion inside the mounting frame 801. During the motion of the transmission plate 802, the sliding pin 702 is driven to make a synchronous horizontal reciprocating motion. During the horizontal reciprocating motion of the sliding pin 702, through the interaction between the sliding pin 702 and the chute 701 on the connecting rod 602, the connecting rod 602 and the connecting shaft 601 on the connecting rod 602 are driven to make a reciprocating rotation.

[0051] Preferably, the control component includes a threaded tube 901 rotatably connected inside the operation box 101. A threaded rod 902 is threadedly engaged with the threaded tube 901. One end of the threaded rod 902 is fixed to the upper end of the mounting frame 801. Two sets of sleeves 903 are fixed inside the operation box 101. The two sets of sleeves 903 are symmetrically arranged on both sides of the threaded tube 901. A sliding rod 904 is slidably connected to the sleeve 903. One end of the sliding rod 904 is fixed to the upper end of the mounting frame 801;

[0052] It should be noted here that: through the linkage component, the threaded tube 901 is rotated. During the rotation of the threaded tube 901, through the meshing transmission between the threaded tube 901 and the threaded rod 902 and the sliding guiding action of the sleeve 903 and the sliding rod 904, the stressed mounting frame 801 makes a lifting motion. Through the lifting of the mounting frame 801 and the horizontal reciprocating motion of the transmission plate 802 and the sliding pin 702, the connecting rod 602, the connecting shaft 601 and the liquid extraction head 103 are stressed to swing by different amplitudes.

[0053] Preferably, the linkage component includes linkage gears 1001 respectively fixed on the threaded tube 901 and the rotating shaft 501. The two sets of linkage gears 1001 are connected and driven by a toothed belt 1002;

[0054] It should be noted here that: during the rotation of the rotating shaft 501, through the connection and driving action between the toothed belt 1002 and the two sets of linkage gears 1001, the threaded tube 901 on the control component is driven to rotate.

[0055] In this solution: a thyroid surgery irrigation device includes the following steps:

[0056] When the thyroid surgery irrigation device is in use, through driving, the irrigation fluid is transported through the delivery pipe 104 and the irrigation head 102 towards the position to be irrigated during the surgery, assisting the irrigation operation during the surgery. During the irrigation process, through the pumping action, the irrigated irrigation fluid and tissue fragments are sucked onto the liquid extraction head 103 and transported out through the return pipe 105, avoiding the impact of the irrigated irrigation fluid and tissue fragments on the surgery. And during the process of sucking the irrigation fluid and tissue fragments, the second motor 806 on the mounting frame 801 drives the reciprocating lead screw 803 to rotate. During the rotation of the reciprocating lead screw 803, through the meshing transmission between the reciprocating lead screw 803 and the threaded sleeve 804 and the guiding effect of the sliding of the guide rod 805, the transmission plate 802 makes a horizontal reciprocating motion inside the mounting frame 801. During the movement of the transmission plate 802, the sliding pin 702 is driven to make a synchronous horizontal reciprocating motion. During the process of the sliding pin 702 making a horizontal reciprocating motion, through the interaction between the sliding pin 702 and the chute 701 on the connecting rod 602, the connecting rod 602 and the connecting shaft 601 on the connecting rod 602 are driven to make a reciprocating rotation (see Figure 9 for the state). Through the reciprocating rotation of the connecting shaft 601, the liquid extraction head 103 is driven to make a reciprocating swing (see Figure 11 for the state). Through the reciprocating motion of the liquid extraction head 103 and the suction effect of the liquid extraction head 103, the recovery effect of the irrigation fluid and tissue fragments left after irrigation is ensured;

[0057] During the initial irrigation and liquid extraction process, the through hole 204 on the sphere 203 is completely communicated with the inside of the irrigation head 102 (see Figure 5In this state, the flow cross-sectional area of the flushing liquid is relatively large, so that the flushing pressure can be set relatively low. At this time, the use angle of the flushing head 102 is kept relatively perpendicular to the flushing position during the operation. The perpendicular angle makes the water flow direction consistent with the normal direction of the tissue surface, and the impact force is concentrated directly below the flushing point. Moreover, due to the low pressure, the impact force is controlled within a very small range, avoiding the pushing or tearing damage to the fragile tissues around the thyroid gland (such as the recurrent laryngeal nerve and parathyroid gland). When flushing needs to be carried out in a high-pressure manner, the first motor 502 drives the rotating shaft 501 and the flushing head 102 at one end of the rotating shaft 501 to rotate. During the rotation of the flushing head 102, the driving shaft 301 is driven to rotate. During the movement of the driving shaft 301, through the meshing transmission between the driving gear 302 and the arc-shaped rack 303, the driving shaft 301 and the sphere 203 at one end of the driving shaft 301 are rotated. Through the rotation of the sphere 203, the through hole 204 rotates towards the inner side of the spherical groove 202, so that the through hole 204 and the spherical groove 202 are arranged in an interleaved manner, reducing the flow cross-sectional area of the flushing liquid on the flushing head 102. Under the action of the same conveying flow rate, the effect of flushing pressure increase is achieved. During the pressure increase process, by rotating the flushing head 102, the use angle of the flushing head 102 after pressure increase is adjusted. Through the angle adjustment, it is avoided that the flushing liquid splashes and affects the surgical vision during high-pressure and perpendicular flushing. Moreover, through the angle adjustment after pressure increase, the impact force is decomposed into vertical and horizontal components. The vertical impact force is reduced, avoiding directly piercing the tissue. At the same time, the horizontal component pushes the waste liquid towards the liquid suction port, improving the suction efficiency of the liquid suction head 103. In addition, the inclined flushing makes the water flow "slide" along the surface of the wound, covering the lateral and deep concave areas that are difficult to reach in the vertical direction. Especially during the adhesion release in the second operation, it can effectively flush the blood oozing and tissue fragments in the scar gap;

[0058] During the rotation of the rotating shaft 501, through the connection and transmission between the toothed belt 1002 and the two groups of linkage gears 1001, the threaded tube 901 on the control component is driven to rotate. During the rotation of the threaded tube 901, through transmission, the mounting frame 801 moves downward. During the downward movement of the mounting frame 801, in cooperation with the lateral reciprocating drive of the transmission plate 802 and the sliding pin 702, the connecting rod 602, the connecting shaft 601 and the liquid suction head 103 are forced to swing more greatly (see Figure 10 the state). Through the greater swing of the liquid suction head 103, after the pressurized flushing, the liquid suction head 103 can effectively suck and recover the locally splashed flushing liquid, ensuring the recovery effect of the flushing liquid left after flushing.
