Description

Technical Field

[0001] The utility model relates to the technical field of oral medical equipment, in particular to a device for extracting the transverse root of a horizontally impacted tooth. Background Art

[0002] With the evolution of human beings, the degeneration of the jaw bone is inconsistent with the width of the jaw bone required for the actual number of teeth, resulting in the bone volume being relatively smaller than the tooth volume, and the jaw bone lacking sufficient space to accommodate all permanent teeth. The third molars that erupt last are most likely to be partially or completely unable to erupt due to insufficient eruption space, which is called impacted teeth. Mesial or horizontal impacted teeth in the mandible are more common in clinical practice. Currently, the extraction methods mostly use surgical cutting handsets and drills to remove part of the buccal and distal alveolar bone, transversely section the crown, and separate the roots to remove resistance. First, the crown is removed, and then a minimally invasive dental elevator is used to loosen the root from the buccal side. When the root is long and adjacent to important surrounding anatomical structures, such as the inferior alveolar nerve and its branches, the root may be damaged during the root extraction process, or complications such as the root entering the parapharyngeal space from the lingual side may occur.

[0003] According to literature, 90% of inferior alveolar nerve injuries are caused by extraction of impacted mandibular third molars, with an incidence of 0.5% to 5.3%. Specific reasons include the close anatomical proximity of the mandibular third molar to the mandibular canal, as well as the extraction method and technique. The incidence of inferior alveolar nerve injury is higher when the root apex is close to the mandibular canal, trauma is severe, the tooth is separated too deeply with a dental drill, or deep root extraction is performed. Inferior alveolar nerve injury can cause incomplete numbness of the lower lip and chin, or may be accompanied by abnormal sensations such as burning and tingling.

[0004] For example, Chinese patent CN203591337U discloses a minimally invasive impacted tooth extractor, which includes a handle, a rod, and a head. The extractor is S-shaped; the head is spoon-shaped, and the end of the head is pointed. Although it can clamp and extract the teeth, it still has the defect of easily damaging oral tissue.

[0005] Existing technologies and tools have many drawbacks when dealing with these types of teeth:

[0006] 1. The confined space within the oral cavity makes operation difficult. Existing tooth extraction tools often fail to function effectively within the confined space of the oral cavity. This limitation makes the tool manipulation less flexible during the operation, increasing the operation time and complexity.

[0007] 2. When extracting horizontally impacted teeth, existing manual and mechanical tools make it difficult to precisely control the force applied, which can easily cause root fractures or damage surrounding teeth and bone tissue. Furthermore, improper extraction force control can cause impaction with oral soft and hard tissues, increasing the risk of postoperative complications.

[0008] 3. During tooth extraction, improper tool handling can easily cause bruises and trauma to the hard palate, gums, and other areas. This bruise not only causes severe pain but also increases the risk of postoperative infection. If an infection develops, it not only prolongs recovery time but can also lead to more serious oral problems.

[0009] The present utility model is designed to solve the common problems in this field, such as bumps on oral soft and hard tissues, traction injuries at the corners of the mouth, the inability to promptly extract blood and saliva from the wound, which affects the operating field of view, low efficiency of exudate suction, and poor patient comfort.

The limiting seat is arranged on the upper end surface of the suction groove, and the upper end surface of the limiting seat is provided with an active cavity and a removal cavity. The layout directions of the removal cavity and the active cavity are perpendicular, and the two side walls of the removal cavity are provided with a removal groove. The active cavity is used to place the toggle block and the magnetic movable part, and the two side walls of the active cavity are provided with a movable groove. The toggle block includes a main body and a toggle part. The main body of the toggle block is arranged in the movable groove and is slidably connected to the movable groove. The toggle part extends from the limiting groove to form a toggle part. The magnetic movable part is hidden in the active cavity and moves along the extension direction of the active cavity under the toggle of the main body of the toggle block.

[0015] Furthermore, the plucking member includes a plucking forceps, a placement seat, and a support rod, the placement seat is provided with a placement cavity for placing the plucking forceps, the support rod is hinged to one end surface of the placement seat to form a hinge portion, and a through hole is provided on the rod body of the support rod away from the hinge portion;

[0016] Wherein, one end of the support rod away from the hinge part is inserted into the extraction cavity, and the magnetic movable part is moved into the through hole by the toggle block, and the support rod is limited on the extraction slot.

[0017] Furthermore, the movable groove is arranged at the head end of the plucking through groove, and the layout direction of the movable groove is perpendicular to the layout direction of the plucking through groove.

[0018] Furthermore, the shifting portion protrudes from the upper end surface of the limiting seat to form a protrusion for the operator to operate.

[0019] Furthermore, the limiting holes are arranged in a direction parallel to the direction in which the operator pulls out the needle;

[0020] The extraction direction is 30 to 45 degrees to the transverse root of the patient's mandibular horizontal impacted third molar.

[0021] Furthermore, the magnetic movable part is adapted to the through hole.

[0022] Furthermore, the device for extracting the transverse root of a horizontally impacted tooth also includes a suction component, which is arranged on the suction groove body and extracts blood, cooling water, and saliva around the root of the second molar.

[0023] Furthermore, the suction member includes a suction pipe, a suction channel, a connecting nozzle, a suction pump, and an exudate tank. The suction channel is built into the body of the suction tank, and one end of the suction channel is arranged on a side close to the surgical area. The other end of the suction pipe is connected to the connecting nozzle to form a suction portion. One end of the suction pipe is detachably connected to the suction portion, and the other end of the suction pipe is connected to the suction pump. The exudate tank is used to store exudate, cooling water, and saliva.

[0024] The extraction pump uses negative pressure suction to extract the exudate, cooling water, and saliva around the root of the second molar into the exudate tank.

[0025] Furthermore, the inflatable parts on both sides of the suction groove are inflated synchronously to attach the suction groove to the second molar to form a suction platform.

[0026] The beneficial effects of the utility model are as follows:

[0027] 1. Through the mutual cooperation between the suction member, the extraction member, and the limiting member, the extraction forceps form a stable limiting effect, which can provide a buffering and limiting effect during the operator's force application, preventing the main body of the extraction forceps from damaging the oral tissue, ensuring the safety and comfort of horizontal impacted tooth extraction, effectively avoiding damage caused by the extraction process, and ensuring that the entire device has the advantages of simple operation during the tooth extraction process, good patient comfort, and strong protection of oral tissue;

[0028] 2. The suction member provided in the suction groove is used to extract the exudate in the oral cavity, thus overcoming the existing problem that medical staff need to manually operate multiple instruments, and still need multiple people to cooperate in suctioning the exudate, which requires tacit cooperation;

[0029] 3. The device of the present invention overcomes the defect of the existing technology that requires the cooperation of multiple people. The exudate in the oral cavity can be extracted by simply triggering the suction button of the suction pump with the foot. This does not affect the manual operation of medical staff and improves the convenience and efficiency of the tooth extraction process.

[0030] 4. Through the negative pressure suction of the extraction pump, cross infection of the oral cavity and the surgical area is prevented, which effectively improves the safety, convenience and work efficiency of oral exudate extraction, and ensures that the entire device has the advantages of strong exudate extraction ability, good oral comfort for patients, high ease of operation and low labor intensity for medical staff.

[0049] The following combination Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 and Figure 12 The present invention is further described in the following embodiments. This embodiment provides a device for extracting the transverse root of a horizontally impacted tooth 6. The device comprises a suction member, an extraction member, and a limiting member. The suction member is detachably fastened to the second molar 7 to form a limiting portion. The limiting member limits the position of the extraction member, and the extraction member extracts the separated tooth root.

[0050] The suction member includes a suction groove 1, an inflation pipe 19, an inflation pump 25, and a support airbag 24. One end of the inflation pipe 19 is connected to the support airbag 24, and the other end of the inflation pipe 19 is connected to the inflation pump 25 to form an inflation portion. The suction groove 1 is buckled and covered on the second molar 7, and the inflation portion is provided on both sides of the suction groove 1, and the suction groove 1 is attached to the second molar 7.

[0051] The limiting member is arranged on the upper end surface of the suction groove 1 and is detachably connected to the removing member.

[0052] Furthermore, there is an anti-slip protrusion 23 on the contact end surface between the support airbag 24 and the second molar 7, and when the air pump 25 inflates the support airbag 24, the support airbag 24 expands and the anti-slip protrusion 23 contacts the second molar 7 to limit the suction groove 1 on the second molar, thereby forming a suction platform in the oral cavity.

[0053] When the air pump 25 is triggered, the air pump 25 inflates the support airbag 24, causing the support airbag 24 to bulge out and limit the suction groove 1 on the second molar 7, thereby forming a stable suction platform;

[0054] Furthermore, the inflatable parts on both sides of the suction groove 1 are inflated synchronously to attach the suction groove 1 to the second molar 7 to form a suction platform.

[0055] The control end of the air pump 25 is arranged on the outer wall of the suction tank 1 and forms a connection end 11 for connecting an external control device;

[0056] The suction member includes a controller 15 and a connecting line 10, one end of the connecting line 10 is connected to the controller 15 for control, and the other end of the connecting line 10 is connected to a connecting end 11 provided on the suction groove 1 (such as Figure 2 As shown, the connecting line 10 and the connecting end 11 are in a state ready for plug-in connection), thereby realizing the control of the air pump 25.

[0057] The controller 15 and the connecting line 10 are disposable and are used by one person only to prevent cross infection between different patients.

[0058] At the same time, through the mutual cooperation of the limiting component and the suction component, the exudate in the oral cavity can be extracted during the extraction process, and the separated tooth roots are clamped by the extraction component, thereby limiting the range of movement of the extraction forceps and reducing the impact on oral tissue during the extraction process.

[0059] Furthermore, the limiting component includes a limiting seat, an active cavity 21, a magnetic active part 20, a toggle block, and a removal cavity 26. The limiting seat is arranged on the upper end surface of the suction groove 1, and the upper end surface of the limiting seat is provided with an active cavity 21 and a removal cavity 26. The layout directions of the removal cavity 26 and the active cavity 21 are perpendicular, and the two side walls of the removal cavity 26 are provided with removal grooves 34. The active cavity 21 is used for placing the toggle block 16 and the magnetic active part 20, and the two side walls of the active cavity 21 are provided with active grooves 32. The toggle block 16 includes a main body and a toggle part 33. The main body of the toggle block 16 is arranged in the active groove 32 and is slidably connected to the active groove. The toggle part 33 extends from the limiting groove to form a toggle part 33. The magnetic active part 20 is hidden in the active cavity 21 and moves along the extension direction of the active cavity 21 under the toggle of the main body of the toggle block 16.

[0060] Furthermore, the plucking member includes a plucking forceps 3, a placement seat 2, and a support rod 4. The placement seat 2 is provided with a placement cavity 27 for placing the plucking forceps 3. The support rod 4 is hinged to one end surface of the placement seat 2 to form a hinge portion 5. The support rod 4 is provided with a through hole 18 on the rod body away from the hinge portion 5.

[0061] The end of the support rod 4 away from the hinge portion 5 is inserted into the extraction cavity, and the magnetic movable part 20 is moved into the through hole 18 by the toggle block 16, and the support rod 4 is limited on the extraction slot.

[0062] Furthermore, the movable groove 32 is provided at the head end of the plucking through groove 34 , and the layout direction of the movable groove 32 is perpendicular to the layout direction of the plucking through groove 34 .

[0063] The toggle portion 33 protrudes from the upper end surface of the limit seat to form a protrusion for the operator to operate.

[0064] The layout direction of the plucking slot 34 is parallel to the plucking direction of the operator;

[0065] The extraction direction is 30 to 45 degrees to the transverse root of the patient's mandibular horizontal impacted third molar.

[0066] In addition, if Figure 7As shown, the movable groove 32 is arranged on one side of the head end of the extraction slot 34, and when the operator toggles the toggle portion 33, the magnetic movable member 20 enters the through hole 18 to limit the movement of the support rod 4. At this time, the operator operates the extraction forceps 3 to clamp the separated tooth root and extract the tooth root skewly upward, so that the placement seat 2, the support rod 4 and the extraction forceps 3 are moved along the end direction of the extraction slot 34, thereby removing the separated tooth root from the surgical area. This time, the placement seat 2, the support rod 4 and the extraction forceps 3 are moved from the end direction of the extraction slot 34 to the head end direction, and the limiting state of the magnetic toggle member is released by the toggle portion 33, so that the support rod 4 can be removed from the extraction cavity 26, thereby realizing the separation and removal of the tooth root;

[0067] Furthermore, the magnetic movable member 20 is adapted to the through hole 18 so that the magnetic movable member 20 can be inserted into the through hole 18 and limit the support rod 4 so that the support rod 4 can be locked on the suction groove 1 to form a stable suction platform;

[0068] Furthermore, the axial diameter of the movable cavity 21 and the axial diameter of the limiting hole 17 are perpendicular to each other, so that the support rod 4 can be limited by the magnetic movable part 20 .

[0069] At the same time, in this embodiment, the placement seat 2 is made of silicone rubber, which has a certain degree of elasticity and hardness. The placement seat 2 is nested in the outer periphery of the extraction forceps 3 to form a structure that limits the extraction forceps, so that the operator can have a buffering and limiting effect during the force application process, preventing the main body of the extraction forceps from causing damage to the tissue in the oral cavity, thereby ensuring the safety and comfort of the extraction of horizontal impacted teeth.

[0070] At the same time, the extraction forceps 3 are placed in the placement cavity 27 and can just clamp the separated horizontal transverse teeth;

[0071] Through the mutual cooperation between the suction component, the extraction component and the limiting component, the extraction forceps 3 forms a stable limiting effect, so that the operator can have a buffering and limiting effect during the force application, preventing the main body of the extraction forceps 3 from causing damage to the tissue in the oral cavity, ensuring the safety and comfort of the extraction of the horizontal impacted tooth 6, and ensuring that the entire device has the advantages of simple operation during the tooth extraction process, good patient comfort, and strong protection of the oral cavity tissue.

[0072] In other embodiments, Figure 10 and Figure 11As shown, the through hole 18 on the support rod 4 can also be set as a passage groove 28, and the passage groove 28 is adapted to the shaft diameter of the magnetic movable member 20. The length of the passage groove 28 is set according to the maximum limit of the mouth opening that different patients can open;

[0073] Among them, the extraction forceps 3 is limited by the placement seat 2, so that after the extraction forceps 3 clamps the tooth root, the range of movement of the extraction forceps 3 is limited, the protection ability of the patient's oral tissue is improved, and the operator is prevented from causing damage to the oral tissue during the process of holding the extraction forceps 3 and applying force to the greatest extent.

[0074] The extraction forceps 3 include a working end 29 and a handheld end 30. The handheld end 30 is for the operator to hold. The working end 29 is used to clamp the horizontal impacted tooth 6 after cutting or punching. One end of the working end 29 is connected to one end of the handheld end 30, and the other end of the working end 29 deviates from the side of the handheld end 30 to extend to form a curved portion. The working end 29 is cylindrical when closed. The working end 29 includes a first circular portion and a second circular portion. The end surfaces facing each other are narrow and long clamping beaks 31 perpendicular to the axis. The clamping beaks 31 are threaded. The depth of the first circular portion and the second circular portion from the curved portion to the port is 1 cm, and the outer diameters of the first circular portion and the second circular portion are 2 mm.

[0075] During use, two circular grooves are first milled longitudinally in the buccal and lingual directions approximately 3 mm from the front end of the transverse section of the tooth root using a surgical high-speed turbine handpiece and a drill. The grooves are 2 / 3 of the root thickness, the distance between the two grooves is approximately 1 / 2 of the buccal and lingual diameter of the root, and each groove is approximately 3 mm wide. The beak of the working end 29 is then inserted into the groove and clamped, and force is applied mesially to the transverse root of the mandibular horizontally impacted third molar, thereby dislocating the root without applying force to the lingual or radicular sides. This reduces the risk of compressing the inferior alveolar nerve and lingual bone plate, or of the root slipping into the parapharyngeal space.

[0076] After the horizontally impacted tooth 6 is separated from the alveolar socket, the tooth root is removed from the oral surgical area;

[0077] Furthermore, the device for extracting the transverse root of the horizontally impacted tooth 6 also includes a suction component, which is arranged on the main body of the suction groove 1 and extracts the blood, cooling water, and saliva around the root of the second molar 7.

[0078] Furthermore, the suction component includes a suction pipe 9, a suction channel 8, a connecting nozzle 22, a suction pump 12, and an exudate tank 13. The suction channel 8 is built into the body of the suction tank 1, and one end of the suction channel 8 is arranged on the side close to the surgical area. The other end of the suction pipe 9 is connected to the connecting nozzle 22 to form a suction part. One end of the suction pipe 9 is detachably connected to the suction part. The other end of the suction pipe 9 is connected to the suction pump 12 (hidden in the exudate tank 13). Figure 2 The exudate tank 13 is connected to the effusion tank 13 for storing exudate, cooling water, and saliva;

[0079] The extraction pump 12 extracts the exudate, cooling water, and saliva around the root of the second molar 7 into the exudate tank 13 by means of negative pressure suction.

[0080] like Figure 3 As shown, the extraction channel 8 ( Figure 3 As shown by the middle dotted line (the dotted line indicates the layout orientation of the extraction pipe 9), a suction trough 1 body is pre-installed, and the saliva and other exudates near the suction trough 1 are extracted through the external extraction part to expose the surgical area formed by the horizontal impacted tooth 6, ensuring that the operator can clearly understand the state of the tooth root, thereby improving the efficiency and reliability of the entire root extraction;

[0081] When one end of the extraction pipe 9 is connected to the extraction part, an exudate flow channel can be formed, so that under the negative pressure suction of the extraction pump 12, the exudate, cooling water (residual or retained during the root cutting process), and saliva in the patient's mouth are extracted and stored in the exudate tank 13;

[0082] In this embodiment, the suction pipe further includes a withdrawal button 14, which is electrically connected to the withdrawal pump 12. When the medical staff triggers the withdrawal button 14, the withdrawal pump 12 withdraws the exudate from the patient's oral cavity through the exudate flow channel under the action of negative pressure suction and stores the exudate in the exudate tank 13.

[0083] The removal button 14 can be arranged on the outer wall of the exudate tank 13 or at a position that can be touched by the feet of the medical staff, so that the medical staff can easily operate it by foot, thereby improving the convenience and reliability of the operation.

[0084] In this embodiment, the exudate in the oral cavity is extracted by a suction member provided in the suction groove 1, thereby overcoming the defects of the existing medical staff requiring manual operation of multiple instruments, still requiring multiple people to cooperate in suctioning the exudate, and requiring tacit cooperation;

[0085] At the same time, by adopting the device of the utility model, the defect of the prior art that multiple people are required to cooperate in operation is solved. The exudate in the oral cavity can be extracted by simply triggering the extraction button 14 of the suction pump by foot, which does not affect the manual operation of medical staff and improves the convenience and efficiency of the tooth extraction process.

[0086] At the same time, the negative pressure suction of the extraction pump 12 is used to prevent the risk of cross infection in the oral cavity and the surgical area, effectively improving the efficiency and convenience of extracting exudate from the oral cavity, ensuring that the entire device has the advantages of strong exudate extraction ability, good oral comfort for patients, high ease of operation, and low labor intensity for medical staff.

[0087] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
