Description

Technical Field

[0001] The utility model belongs to the technical field of dental instruments, and particularly relates to a surgical knife handle assembly for dental use. Background Art

[0002] As the most commonly used surgical tool, a scalpel consists of two parts: a blade and a handle. Existing blades and handles of different shapes and models often have problems of slipping and other discomforts during operations such as cutting, severing, and trimming in the pen-holding style, because the movement and force are mainly on the fingers. Content of the Utility Model

[0003] To solve the above problems, the utility model provides a surgical knife handle assembly for dental use.

[0004] The utility model is realized as follows: a surgical knife handle assembly for dental use includes a blade and a handle. An ergonomic holding point is provided at the front end of the handle close to the blade, and circular protrusions are provided on both sides of the middle part. An oval holding point is provided opposite to the circular protrusions. A spoon head is provided at one end of the handle far from the blade, and the outer edge of the handle is set in the shape of a curve that fits the hand.

[0005] When using the blade to complete the carving and processing of the wax pattern in the oral cavity, during operation, the operator holds the handle. The outer edge of the handle is set in the shape of a curve that fits the hand, which is convenient for holding. Circular protrusions and oval holding points are provided at the middle position as the force application points for the fingers, and the holding is comfortable, which is convenient for applying force during carving and processing. The spoon head provided at the rear end can repair the denture during denture processing and make a small adjustment to the installation position of the denture.

[0006] A fixing head is provided at the front end of the handle. A clamping platform is provided on the fixing head. A jack is provided along the edge of the handle close to the fixing head. The blade is provided with a plug. A clamping groove is provided at the middle position of the blade. The plug is matched with the jack, and the clamping platform is matched with the clamping groove.

[0007] The handle and the blade are designed in a split type. When in use, the plug on the blade is inserted into the jack on the handle, and the clamping platform on the handle is matched with the clamping groove on the blade, so that the blade and the handle are firmly connected together and are also convenient to separate.

[0008] The clamping platform and the clamping groove are in interference fit, and the thickness dimension of the plug is smaller than the depth dimension of the jack, ensuring the firm connection between the blade and the handle.

[0009] The clamping platform and the clamping groove are slender strips, and the aspect ratio is greater than 3, effectively preventing the blade from shaking left and right when cooperating with the handle.

[0010] The described blade is made of stainless steel, and the handle is made of titanium alloy metal. The stainless steel blade is strong and durable, and the titanium alloy metal handle is convenient for processing.

[0011] The described handle is produced by 3D printing technology and can be processed into any shape according to the design.

[0012] The structure of the utility model is reasonably designed. During operation, the operator holds the handle. The outer edge of the handle is set in the shape of a hand-fitting curve, which is convenient for holding. A circular protrusion and a concave holding point are set at the middle position as the force application points for the fingers, providing a comfortable grip. During engraving processing, it is convenient to apply force. The spoon head set at the rear end can repair dentures during denture processing and make small adjustments to the denture installation position, making it easy to use and improving the comfort and operability of the dental scalpel during use.

[0018] In order to more clearly understand the technical solution of the utility model, the utility model will be further described below with reference to the drawings.

[0019] Such as Figures 1-4A surgical knife handle assembly for dental use as shown, comprising a blade 1 and a handle 2. An ergonomic gripping point is provided at the front end of the handle 2 close to the blade 1, and circular protrusions 5 are provided on both sides of the middle section. An arcuate gripping point 4 is provided opposite the circular protrusions 5. A spoon head 3 is provided at one end of the handle 2 away from the blade 1, and the outer edge of the handle 2 is shaped as a hand-fitting curve. A fixing head 7 is provided at the front end of the handle 2, and a clamping platform 8 is provided on the fixing head 7. A jack 9 is provided on the handle 3 closely along the edge of the fixing head 7. A plug 10 is provided on the blade 1, and a clamping groove 11 is provided at the middle position of the blade. The plug 10 is matched with the jack 9, and the clamping platform 8 is matched with the clamping groove 11. The clamping groove 11 is a through hole, and the height of the clamping platform 8 is greater than the thickness of the blade 1. The handle 2 and the blade 1 are of a split design. When in use, the plug 10 on the blade 1 is inserted into the jack 9 on the handle 2, and the clamping platform 8 on the handle 2 is matched with the clamping groove 11 on the blade 1, so that the blade and the handle are firmly connected together and are convenient to separate. The clamping platform 8 and the clamping groove 11 are in interference fit. The thickness dimension of the plug 10 is smaller than the depth dimension of the jack 9, and the overall shape of the plug is smaller than the overall shape of the jack. The clamping platform 8 and the clamping groove 11 are slender strips with an aspect ratio greater than 3, which can effectively prevent the blade 1 from swaying left and right when being matched with the handle 2. The blade 1 is made of stainless steel, and the handle 2 is made of titanium alloy metal. The handle 2 is produced by 3D printing technology.

[0020] The structure of the utility model is reasonably designed, easy to use, and improves the comfortable gripping feeling and operability when using a dental scalpel.

[0021] The above is only the preferred embodiment of the utility model. Therefore, all equivalent changes or modifications made according to the structure, features and principles described in the scope of the utility model patent application are included in the scope of the utility model patent application.
