Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically, to a thyroid gland stripping device. Background Technology

[0002] The thyroid dissection device is a medical instrument used in thyroid surgery to dissect thyroid tissue from the larynx. During the surgery, thyroid surgery requires the coordinated use of multiple medical instruments, such as separators, dissecters, and specialized retractors. These instruments are independent and too scattered. When a particular instrument is needed, it must be searched for in the tray, which is inconvenient for doctors to concentrate on the surgery and may affect the efficiency of the operation. This application proposes a device that can integrate multiple independent instruments for thyroid surgery into one, so that a particular instrument can be used directly when needed, thereby reducing the inconvenience of using independent instruments and the problem of frequent changes. Summary of the Invention

[0003] The present invention aims to solve the technical problems described above in the prior art.

[0004] The objectives and effects of this invention are achieved by the following specific technical means:

A piston is slidably mounted inside the receiving cavity. A detachable instrument component is mounted on the bottom of the piston. A connecting rod is integrally connected to the end away from the instrument components. The free end of the connecting rod extends to the outside of the receiving cavity and is connected to a C-shaped block with the opening of the C-shaped block facing outward. A compression spring is fitted on the outside of the connecting rod in the receiving cavity. An upper limit hole is provided on the outside of the head corresponding to the upper end of the piston, and a lower limit hole is provided on the outside of the head corresponding to the lower end of the piston. An inwardly recessed groove is provided on the outside of the piston corresponding to the upper limit hole. A spring is connected in the groove, and a limiting steel ball is connected to the free end of the spring. The limiting steel ball is pushed by the tension of the spring, causing the free end of the limiting steel ball to insert into the upper limit hole. When the piston moves to the bottom of the receiving cavity, the limiting steel ball is inserted into the lower limit hole.

[0006] Preferably, the instrument component of the receiving cavity is one of a separator, a peeler, or a special pull hook, and the instrument component is fixedly connected to the piston by a thread.

[0007] Preferably, an indicator mark is provided on the outer side of the turntable and an indicator mark is also provided on the outer side of the head. When the indicator mark on the turntable coincides with the indicator mark on the head, the second through hole at the bottom of the turntable corresponds to the first through hole at the bottom of the storage cavity on the corresponding side.

[0008] Preferably, the head is made of a transparent material.

[0009] Preferably, the rotating shaft has a water chamber, an air chamber, and a drain chamber arranged sequentially from top to bottom inside. Except for the receiving chamber corresponding to the second through hole, the water chamber has a second water inlet corresponding to the other receiving chambers. The receiving chamber has a first water inlet corresponding to the second water inlet. Except for the receiving chamber corresponding to the second through hole, the second water inlet on the outside of the water chamber and the first water inlet on the inside of the receiving chamber are connected in a one-to-one correspondence. A water inlet pipe is vertically inserted into the top of the knob. The end of the water inlet pipe is connected to the water chamber. The end of the water inlet pipe located outside the knob is connected to the water guiding device through a telescopic flexible hose.

[0010] Preferably, in addition to the storage cavity corresponding to the second through hole, the outer side of the drain cavity is provided with a second drain outlet corresponding to the other storage cavities. The storage cavity is provided with a first drain outlet corresponding to the second drain outlet. Except for the storage cavity corresponding to the second through hole, the second drain outlet on the outer side of the drain cavity is connected to the first drain outlet on the inner side of the storage cavity. A drain pipe is vertically inserted into the center of the top of the knob. The end of the drain pipe is connected to the drain cavity. The end of the drain pipe located outside the knob is connected to a sealed wastewater storage container through a telescopic flexible hose. A negative pressure pump is installed outside the wastewater storage container. The negative pressure pump can discharge the air from the storage container.

[0011] Preferably, in addition to the receiving cavity corresponding to the second through hole, the outer side of the air chamber is provided with an air inlet 2 corresponding to the other receiving cavities. The receiving cavity is provided with an air inlet 1 corresponding to the second air inlet. Except for the receiving cavity corresponding to the second through hole, the second air inlet on the outer side of the air chamber is connected to the air inlet 1 on the inner side of the receiving cavity. An air inlet pipe is vertically inserted into the top of the knob. The end of the air inlet pipe is connected to the air chamber. The end of the air inlet pipe located outside the knob is connected to the aeration device through a telescopic hose.

[0012] Preferably, except for through hole two, the inner end face of the turntable is connected to the other corresponding storage cavities with rubber rings.

[0013] Preferably, there is a gap between the drain pipe and the rotating shaft. The gap is sealed and not connected to the water chamber, air chamber, and drain chamber. The drain pipe is a rubber tube. A strip-shaped fixing strip is connected circumferentially along the outside of the drain pipe at the gap. The fixing strip is made of rigid material. T-shaped feet are connected to the upper and lower ends of the outer side of the fixing strip. The inner wall of the gap has a groove corresponding to the T-shaped feet. The T-shaped feet are inserted into the groove. At the same time, a spring is connected between the T-shaped feet and the inside of the groove.

[0014] Preferably, the diameter of the free end of the handle increases gradually from the inside to the outside.

[0015] Beneficial effects:

[0016] 1. This thyroid dissection device has a storage cavity that houses various instrument components. All instrument components can be easily extended from the head for use. This design reduces the need for medical staff to search for instrument components and reduces the need to handle instrument components without their hands, thus reducing errors and improving surgical efficiency.

[0017] 2. This thyroid gland removal device is equipped with a drain pipe, a water inlet pipe, and an air inlet pipe. The water guiding device introduces clean water, cleaning solution, disinfectant, or other liquids into the water chamber through the water inlet pipe. The water then enters the receiving chamber through inlet two and inlet one, cleaning the instrument parts after use. Simultaneously, the aeration device is activated, inflating the air chamber through the air inlet pipe. This air is then introduced into the receiving chamber containing the cleaning solution, achieving aeration within the receiving chamber and effectively washing away any dirt adhering to the instrument parts. The negative pressure pump is activated, expelling air from the receiving container and creating negative pressure inside, thus eliminating wastewater. The wastewater enters the drainage chamber through drain outlet 1 and drain outlet 2, and then flows through the drain pipe to the collection container. A drain valve should be installed on the outside of the collection container. When the collection container is two-thirds full, the recycled clean wastewater can be discharged for treatment. When the drain pipe is blocked by impurities, the negative pressure pump can be turned off and the aeration equipment can be started to aerate the collection chamber, thereby introducing air into the drain pipe, causing the drain pipe to expand. At the same time, the impurities are carried out by the air into the collection container. When the drain pipe expands, the fixing bar pushes the T-shaped foot to move into the groove 2 and squeezes the spring. When the aeration equipment stops, the negative pressure pump can be restarted to continue working and discharge the clean wastewater. Attached image description:

Detailed Implementation

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] Reference Figure 1-7 A thyroid gland stripping device includes a head 1 with multiple sets of receiving cavities 101 inside. One end of the head 1 is integrally connected to a handle 2. The head 1 and the handle 2 are coaxially connected. The free end of the handle 2 has a gradually increasing diameter from the inside to the outside, so that the free end of the handle 2 is frustum-shaped, which is convenient for medical staff to hold.

[0028] A rotating shaft 3 is mounted at the center of the handle 2 via a bearing. The lower end of the rotating shaft 3 extends vertically through to the outside of the free end of the head 1 and is connected to a turntable 5. The upper end of the rotating shaft 3 extends through to the outside of the free end of the handle 2 and is connected to a knob 4. The knob 4 can drive the rotating shaft 3 to rotate, and at the same time drive the turntable 5 to rotate synchronously.

[0029] The head 1 is cylindrical in shape. The storage cavity 101 is located inside the head 1 and distributed around the circumference of the rotating shaft 3. The end of the storage cavity 101 near the turntable 5 is provided with a through hole 104. The end face of the turntable 5 is provided with a through hole 501 of the same size corresponding to one of the through holes 104. The inner end face of the turntable 5 is tightly fitted with the free end of the head 1. A piston 6 is slidably arranged inside the storage cavity 101. A detachable instrument component 7 is installed at the bottom of the piston 6.

[0030] Instrument component 7 is a medical device such as a separator, peeler, or special pull hook. The connection between instrument component 7 and piston 6 can be by thread or by insertion and limiting fixation. The principle of insertion and limiting fixation is the same as the steel ball limiting principle of umbrella handle, which facilitates the installation and disassembly of instrument component 7, makes it easy to replace and maintain, and allows different instrument components 7 to be used in combination.

[0031] The piston 6 is integrally connected to a connecting rod 8 at the end away from the instrument component 7. The free end of the connecting rod 8 extends through to the outside of the storage cavity 101 and is connected to a C-shaped block 801. The opening of the C-shaped block 801 faces outward. A compression spring 9 is sleeved on the outside of the connecting rod 8 in the storage cavity 101. The instrument component 7 in the storage cavity 101, which is connected to the corresponding through hole 104 and through hole 2 501, can be pushed by the tension of the compression spring 9 to move the piston 6 downward synchronously. This allows the instrument component 7 to extend out from the openings of through hole 104 and through hole 2 501. The other through holes 104 at the bottom of the storage cavity 101 are closed by the turntable 5.

[0032] The outer side of the head 1 is provided with an upper limit hole 102 corresponding to the upper end of the piston 6, and the outer side of the head 1 is provided with a lower limit hole 103 corresponding to the lower end of the piston 6. The outer side of the piston 6 is provided with an inwardly recessed groove 601 corresponding to the upper limit hole 102. A spring is connected in the groove 601. The free end of the spring is connected to a limiting steel ball 10. The limiting steel ball 10 is pushed by the tension of the spring, so that the free end of the limiting steel ball 10 is inserted into the upper limit hole 102, so that the piston 6 is not pushed downward by the force of the compression spring 9. At this time, the compression spring 9 is in a compressed state.

[0033] When the limiting steel ball 10 is pressed and retracted into the groove 601, the reaction force of the compression spring 9 can push the piston 6 downward. When the piston 6 moves to the lowest end of the storage cavity 101, the limiting steel ball 10 corresponds to the lower limiting hole 103. At this time, the limiting steel ball 10 is pushed to the outside of the groove 601 by the reaction force of the spring, so that the free end of the limiting steel ball 10 is inserted into the lower limiting hole 103, thus limiting the piston 6. In this way, when the instrument part 7 is being operated, the piston 6 will not be forced to move upward. If it is necessary to put the instrument part 7 into the storage cavity 101, the limiting steel ball 10 needs to be pressed, and then the connecting rod 8 is pulled upward by holding the C-block 801 with the index finger until the limiting steel ball 10 is inserted into the upper limiting hole 102. Then the C-block 801 can be released, and the instrument part 7 is put into the storage cavity 101.

[0034] It is important to understand that there are indicator marks on the outside of the turntable 5 and on the outside of the head 1. When the indicator marks on the turntable 5 and the head 1 coincide, it means that the through hole 501 at the bottom of the turntable 5 corresponds to the through hole 104 at the bottom of the corresponding storage cavity 101. A detachable indicator mark is provided on the outside of the head 1 corresponding to the storage cavity 101. The indicator mark indicates the name of the instrument component 7 installed inside the storage cavity 101. Of course, the head 1 can be made of a transparent material, such as transparent plastic, so that medical staff can directly observe the instrument component 7 inside the storage cavity 101.

[0035] In this application, multiple receiving cavities 101 are provided, and different instrument components 7 for thyroid dissection surgery are installed in each independent receiving cavity 101. When the corresponding instrument component 7 is needed, the knob 4 is first used to rotate the turntable 5 so that the second through hole 501 is aligned with the first through hole 104 at the bottom of the corresponding receiving cavity 101. Then, the limiting steel ball 10 is pressed to disengage from the upper limiting hole 102, and the piston 6 is pushed downward by the force of the compression spring 9. The piston 6 then drives the instrument component 7 to extend from the openings of the first through hole 104 and the second through hole 501. At this time, the limiting steel ball 10 enters the lower limiting hole 103 to limit the piston 6. By holding the handle 2, the instrument component 7 extending from the head 1 can be operated. When it is necessary to replace the instrument component 7, press the limiting steel ball 10, and pull the connecting rod 8 through the C-block 801, so that the piston 6 pulls the instrument component 7 into the storage cavity 101. Finally, the limiting steel ball 10 enters the upper limit hole 102 to limit the piston 6. Then, rotate the knob 4 to rotate the second through hole 502 on the bottom end face of the turntable 5 to the bottom of the instrument component 7 to be used, so that the second through hole 502 is vertically aligned with the first through hole 104 at the bottom of the corresponding storage cavity 101. Then repeat the above operation of removing the instrument component 7 to replace different instrument components 7. This design reduces the need for medical staff to search for the instrument component 7 and reduces the need to remove the instrument component 7 from their hands, thus reducing errors and improving surgical efficiency.

[0036] In this embodiment, the rotating shaft 3 is provided with a water cavity 25, an air cavity 26, and a drain cavity 27 from top to bottom inside. Except for the receiving cavity 101 corresponding to the second through hole 501, the outer side of the water cavity 25 is provided with a second water inlet 18 corresponding to the other receiving cavities 101. The receiving cavity 101 is provided with a first water inlet 11 corresponding to the second water inlet 18. It can be understood that, except for the receiving cavity 101 corresponding to the second through hole 501, the second water inlet 18 on the outer side of the water cavity 25 and the first water inlet on the inner side of the receiving cavity 101... 11 are connected in a one-to-one correspondence. A water inlet pipe 302 is vertically inserted into the top of the knob 4. The end of the water inlet pipe 302 is connected to the water chamber 25. The end of the water inlet pipe 302 located outside the knob 4 is connected to the water guiding device 16 through a telescopic hose. The water guiding device 16 can guide cleaning water or liquids such as cleaning solution and disinfectant into the water chamber 25 through the water inlet pipe 302. The liquid enters the storage chamber 101 through the connected water inlet 2 18 and water inlet 11, so that the instrument parts 7 that have just been used can be cleaned.

[0037] In this embodiment, except for the receiving cavity 101 corresponding to the second through hole 501, the outer side of the drainage cavity 27 is provided with a second drain outlet 20 corresponding to the other receiving cavities 101. Each receiving cavity 101 is provided with a first drain outlet 13 corresponding to the second drain outlet 20. It can be understood that, except for the receiving cavity 101 corresponding to the second through hole 501, the second drain outlet 20 on the outer side of the drainage cavity 27 and the first drain outlet 13 on the inner side of the receiving cavity 101 are connected in a one-to-one correspondence. A drain pipe 301 is vertically inserted into the top center of the knob 4. The end of the drain pipe 301 is connected to the drainage cavity 27. The drain pipe 301 is positioned... A sealed wastewater collection container 14 is connected to one end of the knob 4 via a telescopic hose. A negative pressure pump 15 is installed on the outside of the wastewater collection container 14. The negative pressure pump 15 can expel the air from the collection container 14, thereby creating a negative pressure inside the collection container 14. Wastewater enters the drain chamber 27 through drain outlet 13 and drain outlet 20, and then the clean wastewater is discharged to the collection container 14 through the drain pipe 301. A drain valve should be installed on the outside of the collection container 14. When the wastewater in the collection container 14 is two-thirds full, the recovered clean wastewater can be discharged for treatment.

[0038] In this embodiment, except for the storage cavity 101 corresponding to the second through hole 501, the outer side of the air cavity 26 is provided with an air inlet 19 corresponding to the other storage cavities 101. The storage cavity 101 is provided with an air inlet 12 corresponding to the second air inlet 19. It can be understood that, except for the storage cavity 101 corresponding to the second through hole 501, the second air inlet 19 on the outer side of the air cavity 26 is connected to the air inlet 12 on the inner side of the storage cavity 101. An air inlet pipe 303 is vertically inserted into the top of the knob 4. The end of the air inlet pipe 303 is connected to the air cavity 26. The end of the air inlet pipe 303 located outside the knob 4 is connected to an aeration device 17 through a telescopic hose. The aeration device 17 can inflate the air cavity 26 through the air inlet pipe 303, and then introduce the gas into the storage cavity 101 containing cleaning liquid, so as to achieve the effect of aeration in the storage cavity 101, so that the stains on the instrument parts 7 can be washed clean.

[0039] In this embodiment, except for the second through hole 501, the inner end face of the turntable 5 is connected to the other corresponding storage cavities 101 with rubber rings 502. The rubber rings 502 can prevent cleaning liquid from seeping out from the connection gap between the turntable 5 and the head 1, thus achieving a sealing effect.

[0040] In this embodiment, a gap 21 is left between the drain pipe 301 and the rotating shaft 3. The gap 21 is sealed and non-conductive with the water chamber 25, the air chamber 26, and the drain chamber 27. The drain pipe 301 is a rubber tube. A strip-shaped fixing strip 22 is connected circumferentially along the outside of the drain pipe 301 at the gap 21. The fixing strip 22 is made of a rigid material, which can be metal or plastic. T-shaped feet 23 are connected to the upper and lower ends of the outer side of the fixing strip 22. A second groove 24 is provided on the inner wall of the gap 21 corresponding to the T-shaped foot 23. The T-shaped foot 23 is inserted into the second groove 24. At the same time, a spring is connected between the T-shaped foot 23 and the inside of the second groove 24, and the T-shaped foot 23 cannot be moved out of the second groove 24. The spring pushes the T-shaped foot 23 outward. At this time, through The fixing strip 22 and the T-shaped foot 23 provide support, keeping the hollow drain pipe 301 in a circular state. When the negative pressure pump 15 is started, the drain pipe 301 will not flatten due to the support of the fixing strip 22 and the T-shaped foot 23. When the drain pipe 301 is blocked by impurities, the negative pressure pump 15 can be turned off, and the aeration device 17 can be started to aerate the collection chamber 101, thereby introducing air into the drain pipe 301, causing the drain pipe 301 to expand. At the same time, the impurities are carried out by the air into the collection container 14. When the drain pipe 301 expands, the fixing strip 22 pushes the T-shaped foot 23 to move into the groove 24 and squeeze the spring. When the aeration device 17 stops, the negative pressure pump 15 can be started again to continue working and drain the cleaning liquid wastewater.

[0041] Working principle:

[0042] In use, first, rotate the turntable 5 by turning the knob 4, so that the second through hole 501 at the bottom of the turntable 5 rotates to the first through hole 104 at the bottom of the instrument part 7 to be used, so that the second through hole 501 and the first through hole 104 are directly connected. Then, press the limiting steel ball 10 to disengage it from the upper limit hole 102. The piston 6 is pushed downward by the thrust of the compression spring 9. Then, the piston 6 drives the instrument part 7 to extend out from the opening of the first through hole 104 and the second through hole 501. At this time, the limiting steel ball 10 enters the lower limit hole 103 to limit the piston 6. By holding the handle 2, the instrument part 7 extending from the head 1 can be operated. When the instrument part 7 needs to be replaced, press the limiting steel ball 10. The steel ball 10 is positioned so that the connecting rod 8 is pulled by the C-shaped block 801, which causes the piston 6 to pull the instrument component 7 into the storage cavity 101. Finally, the limiting steel ball 10 enters the upper limit hole 102 to limit the piston 6. Then, the knob 4 is rotated to rotate the second through hole 502 on the bottom end face of the turntable 5 to the bottom of the instrument component 7 to be used, so that the second through hole 502 is vertically aligned with the first through hole 104 on the bottom of the corresponding storage cavity 101. Then, the above operation of removing the instrument component 7 is repeated to replace different instrument components 7. This design reduces the need for medical staff to search for the instrument component 7 and reduces the need to remove the instrument component 7 from their hands, thus reducing errors and improving surgical efficiency.

[0043] After instrument component 7 is used and re-enters the storage chamber 101, if the other sets of instrument components 7 have also been used, the water guiding device 16 can be activated. The water guiding device 16 can introduce cleaning water, cleaning solution, disinfectant, or other liquids into the water chamber 25 through the water inlet pipe 302, and into the storage chamber 101 through the connected water inlet 2 18 and water inlet 11, so that the instrument component 7 that has just been used can be cleaned. At the same time, the aeration device 17 can be activated, which can inflate the air chamber 26 through the air inlet pipe 303, and then introduce the gas into the storage chamber 101 containing cleaning solution, so as to achieve the effect of aeration in the storage chamber 101, so that the stains on the instrument component 7 can be washed away. The negative pressure pump 15 is activated, which can expel the air from the storage container 14, thereby making the inside of the storage container 14 clean. A negative pressure is created, and wastewater enters the drainage chamber 27 through drain outlet 13 and drain outlet 20. Then, the clean wastewater is discharged to the collection container 14 through the drain pipe 301. A drain valve should be installed on the outside of the collection container 14. When the wastewater in the collection container 14 is two-thirds full, the recycled clean wastewater can be discharged for treatment. When the inside of the drain pipe 301 is blocked by impurities, the negative pressure pump 15 can be turned off and the aeration device 17 can be started to aerate the collection chamber 101, thereby introducing air into the drain pipe 301, causing the drain pipe 301 to expand. At the same time, the impurities are carried out by the air into the collection container 14. When the drain pipe 301 expands, the fixing bar 22 pushes the T-shaped foot 23 to move into the groove 24 and squeezes the spring. When the aeration device 17 stops, the negative pressure pump 15 can be started again to continue working and discharge the clean wastewater.
