Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work all belong to the protection scope of the present invention.

As shown in fig. 1, the utility model discloses an ultrasonic forceps with antiskid function, it includes cutter arbor 1, antiskid cover 2, annular piece 3, annular dog 4, shell 5, tweezers piece 6, spring 7, transducer 8, slipmat 9, bolt 10 and nut 20.

The cutter bar 1 is used for receiving the energy of ultrasonic waves and cutting. The cutter bar 1 is similar to the ultrasonic cutting knife in shape, the cutter bar is continuously thinned from a cylindrical shape, and a blade shape is formed at an operating end.

The anti-slip sleeve 2 is used for improving the friction force when the tweezers are held by fingers. Specifically, the antiskid sleeve 2 is sleeved outside the cutter bar 1.

The ring blocks 3 are used for fixing the anti-slip cover 2 and facilitating the replacement of the anti-slip cover 2. Specifically, the annular block 3 is fixed outside the cutter bar 1, the anti-slip sleeve 2 is provided with a groove matched with the annular block 3, and the annular block 3 is positioned in the groove, so that the anti-slip sleeve 2 is fixed outside the cutter bar 1. The annular block 3 is used for fixing the anti-slip sleeve 2, and meanwhile, the anti-slip sleeve 2 can be pulled out of the cutter bar 1 by the fixing mode, so that the anti-slip sleeve 2 is convenient to replace.

More specifically, the anti-slip sleeve 2 is made of rubber and is convenient to pull out from the cutter bar 1.

The annular stop block 4 is used for enabling the anti-skid sleeve 2 to be sleeved quickly. Specifically, the annular stop block 4 is sleeved outside the cutter bar 1 and fixed with the cutter bar 1, and one side of the annular stop block 4 is abutted to the anti-slip sleeve 2. So, the antiskid cover 2 directly overlaps and locates in the cutter arbor 1 and inconsistent with annular dog 4, can confirm that the installation of antiskid cover 2 finishes.

The housing 5 serves to protect the tool holder 1 and the transducer 8. In particular, the annular stop 4 is fixed to the casing 5.

The forceps sheet 6 is used for matching with the cutter bar to tweeze out the cut tissue. Specifically, one end of the forceps sheet 6 is hinged with the shell 5.

The spring 7 is used for supporting the forceps sheet and the cutter bar. Specifically, two ends of the spring 7 are respectively fixed on the forceps sheet 6 and the shell 5, the forceps sheet 6 and the cutter bar 1 are opened to form a certain angle when the spring 7 is in a naturally sprung state, and the other end of the forceps sheet 6 and the cutter bar 1 are closed together when the spring 7 is in a compressed state.

The transducer (8) is used for converting electric energy into ultrasonic energy and transmitting the ultrasonic energy to the cutter bar. Specifically, the transducer 8 is located in the housing 5 and fixed to the housing 5, one end of the transducer 8 is fixed to the cutter bar 1, and the other end of the transducer is connected to the host through the conductive ring and the line.

The anti-slip pad 9 is used for improving the friction force when the fingers hold the tweezers. Specifically, the anti-slip pad 9 is fixed on the outer side wall of the tweezers sheet 6, and the anti-slip pad 9 is made of rubber.

The bolt 10 and the nut 20 are used for fixing the anti-slip pad 9 on the outer side wall of the tweezers sheet 6. Specifically, a through hole 61 is formed in the forceps piece 6, an opening 91 is correspondingly formed in the non-slip mat 9, and the bolt 10 penetrates through the through hole 61 and the opening 91 and is in threaded connection with the nut 20, so that the non-slip mat 9 is fixed on the outer side wall of the forceps piece 6.

Due to the large volume of the bolt 10 and the nut 20, the operation end of the forceps sheet 6 and the cutter bar 1 cannot be closed together. Therefore, more specifically, the forceps sheet 6 is bent, and the operating end of the forceps sheet 6 is bent downward to be close to the cutter bar 1, so that the operating end of the forceps sheet 6 can be closed with the cutter bar 1.

More specifically, a row of through holes 61 are formed in the forceps sheet 6 at equal intervals along the length direction. Therefore, after the bolt 10 and the nut 20 are disassembled, the anti-slip pad 9 can move at the tweezers sheet 6, and after the position is confirmed, the bolt 10 is inserted into the corresponding through hole 61 and the corresponding hole 91 for fixing, so that the anti-slip requirements of different users are met.

More specifically, two openings 91 are formed in the two ends of the anti-slip pad 9 corresponding to the size of the through hole 61, the distance between each two openings 91 and the distance between each two adjacent through holes 61 are the same, the number of the bolts 10 and the number of the nuts 20 are two, and the two bolts 10 respectively penetrate through the two openings 91 and the corresponding through holes 61 and are in threaded connection with the nuts 20, so that the anti-slip pad 9 is fixed on the outer side wall of the tweezers sheet 6. So that the anti-slip pad 9 can be firmly fixed on the outer side wall of the forceps sheet 6.

More specifically, the position, between the two bolts 10, of the outer surface of the anti-slip pad 9 away from the forceps piece 6 is serrated, and the outer surface of the anti-slip sleeve 2 is serrated. Therefore, the friction force of the fingers holding the tweezers is larger. Meanwhile, as the bolt 10 and the nut 20 are arranged on the anti-slip pad 9, the anti-slip pad 9 corresponding to the bolt 10 and the nut 20 is arranged in a zigzag manner, which affects the effect of fixing the anti-slip pad 9 on the outer side wall of the tweezers sheet 6, so that the anti-slip pad 9 is shaken, and only the position, between the two bolts 10, of the outer surface, far away from the tweezers sheet 6, of the anti-slip pad 9 is in a zigzag manner.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
