Abstract
Description
Technical Field
[0001] This utility model relates to oral medical devices, and in particular to a posterior tooth scalpel handle. Background Technology
[0002] With the continuous development and progress of oral medicine, the improvement of materials science and manufacturing processes, and the in-depth understanding of oral anatomy and surgical needs, the requirements for the precision of surgical instruments are becoming increasingly higher. Ordinary surgical knife handles are gradually failing to meet the requirements. Currently, most surgical knife handles on the market are ordinary, and their blades are mostly straight. When performing surgery in the posterior tooth area, due to the relatively narrow space, limited field of vision, and complex anatomical structure of the posterior teeth, the operation is often inconvenient. Therefore, there is a need to develop a posterior tooth surgical knife handle. Utility Model Content
[0003] This utility model provides a posterior tooth scalpel handle, the purpose of which is to solve the problem that most existing posterior tooth scalpel handles have a straight head structure, making it difficult to operate on the wound during use.
[0004] To achieve the above objectives, embodiments of this utility model provide a posterior dental scalpel handle, comprising:
[0005] The handle includes a grip portion and a bent portion disposed at the end of the grip portion. A mounting portion is formed at the end of the bent portion away from the grip portion, and a snap-fit member for fixing the blade is disposed on the mounting portion.
[0006] Preferably, the mounting portion is located on a first plane, and the snap-fit member is used to mount the blade parallel to the first plane.
[0007] Preferably, the mounting part is provided with a slot for mounting a snap-fit component, and the snap-fit component is detachably mounted in the slot.
[0008] Preferably, the mounting part is provided with a slot for mounting a snap-fit component, and the snap-fit component is fixed in the slot and integrally formed with the mounting part.
[0009] Preferably, the snap-fit component is provided with a cutting groove arranged around a first axis, and the blade is snapped into the cutting groove, wherein the first axis is perpendicular to the first plane.
[0010] Preferably, the bending angle of the bent portion is greater than 90 degrees and less than 180 degrees.
[0011] Preferably, the gripping part and the bending part are detachably connected.
[0012] Preferably, the gripping part is fixedly connected to the bending part.
[0013] Preferably, the grip portion is provided with knurling.
[0014] Preferably, the diameter of the end of the gripping portion away from the bending portion gradually decreases.
[0015] The above-mentioned solution of this utility model has the following beneficial effects:
[0016] In this application, the holding part and the mounting part are set in a bent relationship by means of a bending part. When using this application, it can help doctors to perform operations such as cutting and separating tissues better, thereby improving the accuracy and safety of the operation. At the same time, the bending part can also serve as a fulcrum to provide stable support and a suitable angle for the blade, allowing doctors to control the direction and force of the blade more precisely.
[0017] Other features and advantages of this invention will be described in detail in the following detailed description section. Attached Figure Description

[0023] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.
[0024] like Figure 1-3 As shown, an embodiment of the present invention provides a posterior dental scalpel handle, including a handle, wherein the handle includes a gripping part 1 and a bending part 2, the bending part 2 is disposed on one end of the gripping part 1, and a mounting part 3 is formed on the end of the bending part 2 away from the gripping part 1, and a snap-fit member 4 is disposed on the mounting part 3 for fixing the blade.
[0025] In this application, the bending part 2 is used to adjust the positional relationship between the gripping part 1 and the mounting part 3, so that the mounting part 3 and the gripping part 1 are bent. The bending part 2 can serve as a fulcrum to provide stable support and a suitable angle for the blade. At the same time, under the bending action of the bending part 2, the doctor can operate in the narrow space of the oral cavity. Compared with the conventional straight-tipped scalpel handle, it can better help the doctor cut and separate tissues.
[0026] Furthermore, the mounting part 3, the bending part 2, and the holding part 1 are all located on the first plane. The snap-fit part 4 is used to fix the blade. After the blade is fixed on the snap-fit part 4, the blade is parallel to the first plane. A slot is provided on the mounting part 3 for mounting the snap-fit part 4.
[0027] In some embodiments, the snap-fit component 4 is detachably disposed within the slot, facilitating its removal and replacement. The snap-fit engagement between the snap-fit component 4 and the slot can employ existing technologies, such as ribs and grooves.
[0028] In some embodiments, the snap-fit 4 is integrally formed with the mounting part 3 to avoid infection caused by unsanitary corners.
[0029] Furthermore, a blade groove 41 for mounting the blade is provided on the snap-fit component 4, and the blade groove 41 is arranged around the first axis on the snap-fit component 4. The blade is snapped into the blade groove 41. The blade is detachably connected to the snap-fit component 4, facilitating blade replacement. The first axis is perpendicular to the first plane.
[0030] Preferably, the bending angle R of the aforementioned bending portion 2 is greater than 90 degrees and less than 180 degrees.
[0031] Preferably, the gripping part 1 and the bending part 2 are fixedly connected or integrally formed.
[0032] Preferably, the gripping part 1 and the bending part 2 are detachably connected, making it convenient to replace the bending part 2 with different bending angles, so that this application can be adapted to different surgical environments.
[0033] Preferably, the grip portion 1 is provided with knurling, which can increase the friction between the hand and the grip portion 1 and prevent slippage during use.
[0034] Preferably, the diameter of the end of the gripping part 1 away from the bending part 2 gradually decreases. The end of the gripping part 1 away from the bending part 2 can be used to pry open tissues, remove bone fragments, etc.
[0035] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
