Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a dual-function oral surgical instrument adapted for posterior tooth region surgery. Background Technology

[0002] During oral surgery, different surgical instruments are needed to perform different procedures. For example, cutting instruments are needed to cut tissue, and dissecting instruments are needed to dissect tissue.

[0003] Single-function surgical instruments lead to frequent instrument changes during surgery, prolonging the operation time. In addition, most surgical instruments have straight handles or a single curved structure, which cannot effectively avoid obstruction from adjacent teeth, causing obstruction of the surgical field and reducing the accuracy of operation during use. Utility Model Content

[0004] The purpose of this invention is to at least solve the problems of reducing surgical time and improving operational precision. This purpose is achieved through the following technical solution:

[0005] This utility model proposes a dual-function oral surgical instrument adapted for posterior tooth region surgery, the dual-function oral surgical instrument comprising:

[0006] An operating handle having a first end and a second end that are arranged in opposite directions;

[0007] An operating lever is provided, with one operating lever connected to each of the first and second ends. The operating lever comprises a first segment, a second segment, and a third segment connected in sequence. The first segment, the second segment, and the third segment are coplanar. The first segment is connected to the operating handle and is coaxially arranged. The second segment and the first segment are arranged at a first included angle, b1, where 110°≤b1≤150°. The second segment and the third segment are arranged at a second included angle, b2, where 70°≤b2≤100°.

[0008] A first working head is connected to the operating lever at the first end, and the first working head has the function of cutting and peeling tissue.

[0009] The second working head is connected to the operating lever at the second end, and the second working head has the function of cutting and peeling tissue.

[0010] According to this utility model, a dual-function oral surgical instrument adapted for posterior tooth surgery has a first working head and a second working head with different functions connected to the first and second ends of the operating handle, respectively. During surgery, this dual-function oral surgical instrument can not only cut tissue but also dissect tissue, thereby increasing the functionality of oral surgery, reducing the need for frequent changes of surgical instruments during the procedure, and effectively shortening the operation time.

[0011] Furthermore, by setting the operating lever into three connected segments (first, second, and third) and adjusting the angle between adjacent segments, the operating lever achieves a bent structure. This bent structure avoids obstruction from adjacent teeth, resulting in a wider field of vision during surgery. The bent structure of the operating lever also conforms to the contours of the teeth in the patient's mouth, facilitating control of the working end's position during surgery, thereby improving accuracy and safety.

[0050] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0051] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0052] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0053] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented as "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0054] like Figures 1 to 3 As shown, according to an embodiment of the present invention, a dual-function oral surgical instrument 100 adapted for posterior tooth region surgery is proposed. The dual-function oral surgical instrument 100 includes an operating handle 10, an operating rod 20, a first working head 30, and a second working head 40.

[0055] Specifically, the operating handle 10 is a rod-shaped structure with a first end and a second end arranged in opposite directions. Each of the first and second ends is connected to an operating rod 20. The operating rod 20 is a bent rod-shaped structure and includes a first segment 21, a second segment 22, and a third segment 23 connected in sequence. The first segment 21, the second segment 22, and the third segment 23 are coplanar. The first segment 21 is connected to the operating handle 10 and is coaxially arranged. The second segment 22 is set at a first included angle b1 with the first segment 21. The first included angle b1 is b1, 110°≤b1≤150°. The second segment 22 is set at a second included angle b2 with the third segment 23. The second included angle b2 is b2, 70°≤b2≤100°. The first working head 30 is connected to the operating rod 20 at the first end and has the function of cutting and peeling tissue. The second working head 40 is connected to the operating rod 20 at the second end and has the function of cutting and peeling tissue.

[0056] According to the present invention, a dual-function oral surgical instrument 100 has a first working head 30 and a second working head 40 with different functions connected to the first and second ends of the operating handle 10, respectively. During surgery, this dual-function oral surgical instrument 100 can not only cut tissue but also dissect tissue, thereby increasing the functionality of oral surgery, reducing the need for frequent changes of surgical instruments during the procedure, and effectively shortening the operation time.

[0057] Furthermore, by configuring the operating lever 20 into connected segments 21, 22, and 23, and adjusting the angle between adjacent segments, the operating lever 20 achieves a bent structure. The first working head 30 and the second working head 40 are respectively connected to the first and second ends via an operating lever 20. In use, the end of the operating lever 20 with the working head is inserted into the patient's oral cavity. The bent structure avoids obstruction from adjacent teeth, providing a wider field of vision during surgery. The bent structure of the operating lever 20 conforms to the contours of the teeth in the patient's oral cavity, facilitating control of the working head position during surgery, thereby improving accuracy and safety.

[0058] It should be understood that the first segment 21 and the third segment 23 are respectively connected to opposite ends of the second segment 22. Along the radial direction of the second segment 22, the first segment 21 and the third segment 23 are located on opposite sides of the second segment 22, that is, the first segment 21 and the third segment 23 extend and are respectively arranged on opposite sides of the radial direction of the second segment 22. In this way, the operating lever 20 can be positioned... The structure is designed so that the operating lever 20 can avoid obstruction from adjacent teeth during use, thus improving the positional accuracy of the working head.

[0059] Furthermore, the length of the second segment 22 is greater than the length of the first segment 21 and the length of the third segment 23, respectively, while the lengths of the first segment 21 and the third segment 23 are approximately equal. The first working head 30 is fixed to the end of the third segment 23 of an operating lever 20 that faces away from the second segment 22. This allows the third segment 23 to carry the first working head 30, avoiding the position of adjacent teeth, thus ensuring the first working head 30 has sufficient travel to reach the affected area (e.g., the posterior teeth region inside the mouth). The second working head 40 is fixed to the end of the third segment 23 of another operating lever 20 that faces away from the second segment 22. This allows the third segment 23 to carry the second working head 40, avoiding the position of adjacent teeth, thus ensuring the second working head 40 has sufficient travel to reach the affected area (e.g., the posterior teeth region inside the mouth).

[0060] It should be noted that the first segment 21 and the second segment 22 are set at a first included angle b1, with a setting of 110°≤b1≤150°. This setting allows the end of the second segment 22 connected to the first segment 21 to be raised upwards, so that the end of the third segment 23 connected to the second segment 22 is raised upwards simultaneously. This facilitates the end of the third segment 23 facing away from the second segment 22, allowing the working head to avoid obstruction from teeth such as anterior teeth, thus enabling the working head to enter the required position (e.g., the posterior tooth region in the oral cavity). The specific value of b1 can be 110°, 115°, 120°, 125°, 130°, 135°, 140°, 145°, or 150°.

[0061] The first segment 21 and the second segment 22 are connected by a first arc, which makes the connection between the first segment 21 and the second segment 22 smooth, reduces the risk of scratches to the patient during use, and improves safety. The radius r1 of the first arc can be 8mm, 8.5mm, 9mm, 9.5mm, or 10mm.

[0062] In addition, the first segment 21 and the second segment 22 can be an integral structure, or they can be connected and fixed by welding or other methods.

[0063] The third segment 23 and the second segment 22 are positioned at a second included angle b2, with a setting of 70°≤b2≤100°. This setting allows the end of the third segment 23 facing away from the second segment 22 to tilt downwards, enabling the working head to reach the required position during the procedure (e.g., the posterior tooth region within the oral cavity) after avoiding adjacent teeth. The specific value of b2 can be 70°, 75°, 80°, 85°, 90°, 95°, or 100°.

[0064] The second segment 22 and the third segment 23 are connected by a second circular arc, which makes the connection between the second segment 22 and the third segment 23 smooth, reduces the risk of scratches to the patient during use, and improves safety. The radius r2 of the second circular arc can be 6mm, 6.5mm, 7mm, 7.5mm, or 8mm.

[0065] In addition, the third segment 23 and the second segment 22 can be an integral structure, or they can be connected and fixed by welding or other methods.

[0066] Furthermore, the operating lever 20 can be a metal component or a non-metallic component. In this application, the operating lever 20 is a metal component, for example, a titanium alloy component. This improves the structural strength of the operating lever 20 and reduces the possibility of deformation.

[0067] In this application, the length of the operating handle 10 is 120 mm and the diameter is 12 mm, which improves the operator's grip comfort during use and further improves the accuracy during operation.

[0068] In some embodiments of this utility model, the cross-section of the first segment 21 is progressively decreasing along the direction from the operating handle 10 to the second segment 22, so that the outer peripheral surface of the first segment 21 is a chamfered surface.

[0069] Specifically, by setting a chamfered surface to accommodate the pen-holding method used by the operator, the operator's grip comfort during use is further improved, and the position of the working head is effectively controlled, thereby improving the positional accuracy of the working head.

[0070] In some embodiments of this utility model, the first working head 30 is a first spoon shape, which has the function of peeling off tissue. The opening of the first spoon shape includes a first cutting edge 31, which is used to cut tissue.

[0071] Specifically, by setting the first working head 30 into a first spoon shape, the opening position of the first spoon shape can be used to form a first cutting edge 31, so as to realize the function of cutting tissue.

[0072] In addition, by setting the first spoon-shaped opening as the first cutting edge 31, the position of the first cutting edge 31 can be increased, thereby increasing the coverage of the first working head 30 and further improving the convenience for the operator during use.

[0073] In addition, the other positions of the first spoon-shaped part, except for the first cutting edge 31, can achieve the function of dissecting tissue during the operation.

[0074] It should be noted that the first working head 30 can be a metal part or a non-metal part (such as a carbon fiber part).

[0075] For example, the first working head 30 is made of titanium alloy, which can improve the strength and wear resistance of the first working head 30, thereby increasing the service life of the first working head 30.

[0076] In addition, the first working head 30 and the operating lever 20 can be an integral structure or a separate structure. For example, the first working head 30 and the operating lever 20 can be separate structures, with a detachable connection between them (such as a threaded connection). By replacing the first working head 30 with a different structure, the first working head 30 can have different functions, further improving the convenience for the operator during use.

[0077] In some embodiments of this utility model, the thickness of the cutting edge 31 is in the range of 0.2 mm to 0.3 mm.

[0078] Specifically, the first working head 30 is set in the shape of a first spoon, and the opening of the first spoon shape is set as a cutting edge 31. By setting the thickness of the cutting edge 31 in the range of 0.2mm to 0.3mm, the sharpness of the cutting edge 31 is improved, thereby improving the convenience of the cutting process.

[0079] It should be noted that the thickness of the cutting edge 31 can be 0.2mm, 0.22mm, 0.24mm, 0.26mm, 0.28mm, or 0.3mm.

[0080] In addition, when the first working head 30 is a metal part, the cutting edge 31 is formed by laser precision grinding.

[0081] In some embodiments of this utility model, the length of the first spoon shape is in the range of 4.8mm to 5.2mm. Specifically, the length of the first spoon shape is greater than its width. By setting the length of the first working head 30, the coverage area of ​​the first working head 30 is increased, thereby improving the convenience for the operator during use.

[0082] It should be noted that the length of the first spoon shape can be 4.8mm, 4.9mm, 5mm, 5.1mm, or 5.2mm.

[0083] In some embodiments of this utility model, the width of the first spoon-shaped part is in the range of 4.3mm to 4.7mm. Specifically, by setting the width of the first working head 30, which is the first spoon-shaped part, the size of the first working head 30 can be made small, reducing the possibility of interference between the first working head 30 and the teeth during the operation, thereby improving the convenience of the surgical operation and enabling the smooth implementation of the surgical operation.

[0084] It should be noted that the width of the first spoon shape can be 4.3mm, 4.4mm, 4.5mm, 4.6mm, or 4.7mm.

[0085] In some embodiments of this utility model, the depth of the first spoon shape is in the range of 1 mm to 4 mm.

[0086] Specifically, by setting the depth of the first spoon shape, the first working head 30 can have a certain capacity to accommodate, reducing the need for cutting tissues.

[0087] It should be noted that the depth of the first spoon shape can be 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, or 4mm.

[0088] In some embodiments of this invention, the surface of the first spoon-shaped part is provided with a first coating, which includes a titanium nitride coating. By providing the first coating layer, the wear resistance of the first working head 30 is improved, thereby extending the service life of the first working head 30.

[0089] In some embodiments of this utility model, a first reinforcing rib 50 is provided between the first working head 30 and the third section 23, and the thickness of the first reinforcing rib 50 is in the range of 1.2mm to 1.8mm.

[0090] Specifically, the first reinforcing rib 50 is connected to the third segment 23 and the first working head 30 respectively. By setting the first reinforcing rib 50, the connection strength between the first working head 30 and the third segment 23 is improved, the deformation problem during use is reduced, and the accuracy of intraoperative operation is improved.

[0091] It should be noted that the thickness of the first reinforcing rib 50 can be 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, or 1.8mm.

[0092] In some embodiments of this utility model, the second working head 40 is a second spoon shape, which has the function of peeling off tissue. The opening of the second spoon shape includes a second cutting edge, which is used to cut tissue.

[0093] Specifically, by setting the second working head 40 into a second spoon shape, the opening position of the second spoon shape can be used to form a second cutting edge 41, so as to realize the function of cutting tissue.

[0094] In addition, by setting the second spoon-shaped opening as the second cutting edge 41, the position of the second cutting edge 41 can be increased, thereby increasing the coverage of the second working head 40 and further improving the convenience for the operator during use.

[0095] In addition, the second spoon-shaped part, except for the second blade 41, can perform tissue dissection during the operation.

[0096] It should be noted that the second working head 40 can be a metal part or a non-metal part (such as a carbon fiber part).

[0097] For example, the second working head 40 is made of titanium alloy, which can improve the strength and wear resistance of the second working head 40, thereby increasing its service life.

[0098] In addition, the second working head 40 and the operating lever 20 can be an integral structure or a separate structure. For example, the second working head 40 and the operating lever 20 can be separate structures, with a detachable connection between them (such as a threaded connection). By replacing the second working head 40 with a different structure, the second working head 40 can have different functions, further improving the convenience for the operator during use.

[0099] In addition, the opening direction of the second spoon shape is set opposite to that of the first spoon shape, which improves the convenience of use.

[0100] In some embodiments of this invention, the width of the second spoon-shaped part is in the range of 4.3mm to 4.7mm. Specifically, by setting the width of the second working head 40, which is shaped like a second spoon, the second working head 40 can be made compact, reducing the possibility of interference between the second working head 40 and the teeth during the operation, thereby improving the convenience of the surgical operation and enabling the smooth implementation of the surgical operation.

[0101] It should be noted that the width of the second spoon shape can be 4.3mm, 4.4mm, 4.5mm, 4.6mm, or 4.7mm.

[0102] In some embodiments of this invention, the depth of the second spoon shape is in the range of 1 mm to 4 mm.

[0103] Specifically, by setting the depth of the second spoon shape, the second working head 40 can have a certain capacity to accommodate materials, reducing the need for cutting tissues.

[0104] It should be noted that the depth of the second spoon shape can be 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, or 4mm.

[0106] Specifically, the second reinforcing rib 60 is connected to the third segment 23 and the second working head 40 respectively. By setting the second reinforcing rib 60, the connection strength between the second working head 40 and the third segment 23 is improved, the deformation problem during use is reduced, and the accuracy of intraoperative operation is improved.

[0107] It should be noted that the thickness of the second reinforcing rib 60 can be 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, or 1.8mm.

[0108] In some embodiments of this invention, the surface of the second spoon-shaped part is provided with a second coating, which includes a titanium nitride coating. By providing the second layer, the wear resistance of the second working head 40 is improved, thereby extending the service life of the second working head 40.

[0109] In some embodiments of this utility model, at least a portion of the outer peripheral surface of the operating handle 10 is provided with an anti-slip structure 11.

[0110] Specifically, by setting an anti-slip structure 11, the operator's grip during use is improved, the risk of the operating handle 10 slipping is reduced, and the safety during use is further improved.

[0111] It should be noted that the anti-slip structure 11 can be a silicone sleeve fitted on the operating handle 10, or it can be an anti-slip structure 11 (such as a textured structure or groove) set on the outer peripheral surface of the operating handle 10.

[0112] In some embodiments of this utility model, the anti-slip structure 11 is a plurality of annular grooves formed on the outer peripheral surface of the operating handle 10, and the plurality of annular grooves are spaced apart along the circumference of the operating handle 10.

[0113] Specifically, the anti-slip structure 11 is configured as multiple annular grooves formed on the operating handle 10. This structure is simple and can improve the anti-slip effect.

[0114] It should be noted that the operating handle 10 can be a metal part or a non-metal part. For example, if the operating handle 10 is a metal part, multiple annular grooves can be formed on the outer peripheral surface of the operating handle 10 by laser etching.

[0115] In addition, multiple grooves are equally spaced along the circumferential direction of the operating lever 20.

[0116] In addition, the annular groove is manufactured using CNC machining.

[0117] In some embodiments of this invention, the depth of the annular groove is in the range of 0.4 mm to 0.6 mm.

[0118] Specifically, by setting the depth of the annular groove within the range of 0.4mm to 0.6mm, the annular groove can have sufficient depth, thereby achieving a better anti-slip effect.

[0119] It should be noted that the specific depth of the annular groove can be 0.4mm, 0.45mm, 0.5mm, 0.55mm, or 0.6mm.

[0120] In some embodiments of this utility model, the interval between two adjacent annular grooves is in the range of 1.5mm to 2.5mm.

[0121] Specifically, by setting the interval between two adjacent annular grooves within the range of 1.5mm to 2.5mm, multiple annular grooves can be set within a suitable interval range, thereby achieving a better anti-slip effect.
