阅读说明：本技术 具有rfid应答器的牙科手持件或手术手持件 (Dental or surgical handpiece with RFID transponder ) 是由 J·索特 J·斯特姆普弗雷 于 2019-09-25 设计创作，主要内容包括：根据本发明,提供一种牙科手持件或外科手持件,它具有细长的握持套(110)、安置在握持套(110)前端且用于可分离地容纳牙科工具的机头部(50)、形成在机头部(50)中且用于可分离地保持工具的夹持机构(20),该夹持机构具有用于操作夹持机构(20)的按钮(10)。该手持件还具有设置用于识别手持件的RFID应答器(5)。在此,按钮(10)由隔热的不导电的塑料或陶瓷材料制成,在该塑料或陶瓷材料中形成安置RFID应答器(5)的盘状凹部。按钮(10)呈扁平圆形,因此RFID应答器(5)因其线圈也呈扁平圆形而可被很好整合加入。因为按钮(10)由不导电材料构成,故对于RFID应答器可获得很好的电环境条件。由于按钮(10)由隔热材料构成,故形成有利的绝热。(According to the invention, a dental or surgical handpiece is provided, having an elongated grip sleeve (110), a handpiece (50) arranged at the front end of the grip sleeve (110) for detachably receiving a dental tool, a gripping means (20) formed in the handpiece (50) for detachably holding the tool, the gripping means having a push button (10) for operating the gripping means (20). The handpiece also has an RFID transponder (5) arranged to identify the handpiece. The push button (10) is made of a thermally insulating, electrically non-conductive plastic or ceramic material, in which a disk-shaped recess is formed, in which the RFID transponder (5) is accommodated. The button (10) is flat and round, so that the RFID transponder (5) can be integrated very well because its coil is also flat and round. Since the push button (10) is made of a non-conductive material, good electrical environmental conditions are obtained for the RFID transponder. Since the push button (10) is made of a heat insulating material, favorable heat insulation is formed.)

1. A dental or surgical handpiece (100), the dental or surgical handpiece (100) having:

2. A dental or surgical handpiece according to claim 1, characterized in that the RFID transponder (5) placed in the recess (11) is encapsulated with a filler (15).

3. A dental or surgical handpiece according to claim 2, characterized in that the RFID transponder (5) is at a distance from the bottom surface (12) of the disc-shaped recess (11), wherein the area between the RFID transponder (5) and the bottom surface (12) is filled with a filler (15).

4. A dental or surgical handpiece according to claim 2 or 3, characterized in that a filler (15) filling the disc-shaped recess (11) and surrounding the RFID transponder (5) forms a raised area (16) with respect to the surrounding surface area (13) of the button (10), wherein the recess (11) and the raised area (16) preferably have an approximately circular outer contour.

5. A dental or surgical handpiece according to claim 4, characterized in that the maximum protruding dimension of the filling (15) with respect to the peripheral surface area (13) of the button (10) is less than 2mm, preferably 1 to 2 mm.

6. A dental or surgical handpiece according to claim 5, characterized in that the protruding filling (15) extends substantially continuously over the surrounding surface area (13) of the button (10).

7. Dental or surgical handpiece according to any of the previous claims, characterized in that the button (10) is arranged on the top side of the handpiece (50) opposite to the tool (120), wherein the disc-shaped recess (11) is preferably formed substantially centrally on the button (10).

8. A dental or surgical handpiece according to any one of the preceding claims, wherein the plastic is Polyetheretherketone (PEEK).

9. Dental or surgical handpiece according to any of the previous claims, characterized in that the filler (15) is of resin and/or silicone.

10. Dental or surgical handpiece according to any of the previous claims, characterized in that the grip sleeve (110) and the handpiece (50) are made of metal.

11. Dental or surgical handpiece according to any of the previous claims, characterized in that the grip sleeve (110) is constructed curvedly.
